Description

A product oil pipeline leakage control device

technical field

The utility model relates to a pipeline leakage control device for controlling after leakage of a product oil pipeline. It relates to the technical field of piping systems.

Background technique

Leakage control is an important means to prevent accidents from expanding and reduce accident losses. Once a product oil pipeline leaks, even if it is necessary to stop the transmission and close the line shutoff valves upstream and downstream of the leak point, since the oil pipeline is not on the same level, as long as the leak point is not at the highest point of the cut off pipeline section, there will be an elevation If there is a difference, the leak point will spray oil outward due to the static pressure of the pressure difference. When the static pressure reaches a certain level, it will break through the soil layer and spray into the air, which is often the case. The result is not only waste, but also pollute the environment, the consequences are extremely serious. And once this happens, according to the current technology, not only will the emergency repair personnel not be able to get close to the injection site, but also because of the high injection pressure, it is impossible to cover the drainage cover with manual force, let alone block it, so they have to let the oil Repair after spraying. As the pressure on long-distance pipelines continues to increase and enterprises and society attach importance to environmental protection, there are still many areas to be improved in terms of emergency repair equipment configuration and construction technology after pipeline leakage, especially for high pressure, environmental risks, and poor social support. For refined oil pipelines, it is particularly important to select appropriate construction equipment and scientific construction techniques. In fact, although none of us would like to see oil product pipelines leaking, it is often unavoidable. This presents us with a technical issue of emergency repair after a leak occurs.

The actions of the arm 2, the large boom 3 and the oil spill recovery device 1 are controlled; the signal sent by the monitoring system 5 is transmitted to the remote control system 11 through the cable carried by the cable retracting and releasing system 10. The monitoring system 5 realizes the environmental monitoring of the road and the surroundings of the leakage point and the monitoring of the injection situation of the leakage point through the remote control system 11, and guides the remote control operation.

Wherein said crawler belt traveling system 4 (see Fig. 4, Fig. 5) is made up of vehicle frame (chassis part), rubber track 20, carrier sprocket device 17, roller device 18, tensioning device 16, driving wheel device 19 and walking Composed of motors, a driving wheel device 19 is installed on both sides of the rectangular parallelepiped frame, and two rubber crawlers 20 each bypass the driving wheel device 19 and form a closed-loop belt through the roller device 18, the tensioning device 16, and the supporting sprocket device 17. .

Described supporting platform system 9 (seeing Fig. 2, Fig. 3) is made up of car body platform, counterweight, and counterweight is reset at the rear portion of car body platform.

Described obstacle removal support system 8 (see Fig. 6) is made up of fender bracket 22, obstacle removal support oil cylinder 23, oil cylinder fender 21, and two fender brackets 22 and oil cylinder fender 21 are fixedly connected into "∏ In the middle of the oil cylinder fender 21, a barrier-removing support cylinder 23 is installed, and the oil cylinder fender 21 is a shovel-shaped bulldozer. hinge connection.

The oil leakage recovery device 1 (see FIG. 9 ) includes an oil collection pipe bracket part 24, an oil collection pipe 25, an oil collection cover 35, a protective claw 36, a needle-like peak 37, an oil collection pipe 39 and a connection reinforcement part 38, which is tapered The thin end of the straight cylindrical oil collection cover 35 is connected to the oil collection pipe 39, and the oil collection pipe 39 is connected to the oil collection pipe 25 fixed by the oil collection pipe bracket part 24, and a plurality of protective claws 36 are installed at intervals around the thick mouth, and the protective claws 36 are densely distributed The needle-shaped spikes 37 and the outer periphery of the oil collection cover 35 are fixedly connected with a connection strengthening part 38 .

The oil spill recovery device 1 is a key part of the whole device, and its structure should consider both the oil collection efficiency and the strength and explosion-proof performance. The oil collection efficiency refers to making full use of the injection energy of the oil to collect as much oil as possible from the injection; for the oil that cannot be collected, the degree of atomization should be reduced as much as possible. When the oil leakage recovery device 1 is working, it is the closest part of the device to the sprayed oil stream. The static electricity carried by the high-speed sprayed oil is most likely to discharge the oil collector. The design of the oil spill recovery device 1 should avoid the A spark discharge is generated. At the same time, when the oil spill recovery device 1 approaches the injection port, it is very likely to collide with hard objects on the ground, so when selecting materials, soft metal materials that can avoid collision sparks should be selected.

The multiple needle-shaped peaks 37 can disperse the energy of the electrostatic discharge, so that the form of the discharge can be controlled within the range of the form of the corona discharge.

The cable take-up and pay-off system 10 (see FIGS. 1 and 2 ) includes a cable reel and an explosion-proof motor 12 for driving the cable reel.

Although the power of the leakage control device can have several forms of fuel engine, AC motor and DC motor, although the fuel engine is more suitable for walking equipment, it is difficult to solve the explosion-proof performance; The capacity and installation space are limited. Comprehensive comparison, it is appropriate to choose explosion-proof AC motor as the power of the device. Explosion-proof AC motors rely on power cables to transmit energy, and the retraction and retraction of the power cables has become a bottleneck problem in the remote control walking distance of the device.

The retracting and unwinding of the cable can be realized by the cable reel. Generally, there are two options for placing the cable reel: one is to place it near the generator car; the other is to place it on the running gear. The advantage of option one is that the weight and overall size of the traveling device are reduced, and the cable reel may not have explosion-proof performance. But there are two unavoidable shortcomings: ① With the movement of the walking device, the cable is dragged on the ground from beginning to end, and the cable is severely worn; ② The cable is always in a state of tension. Inflection point, when the inflection point is increased, the pulling force of the cable and the friction between the cable and the inflection point will be greatly increased, increasing the possibility of cable damage. Therefore, the present invention selects option two. Select the explosion-proof cable reel driven by the explosion-proof motor 12 for use, and install it on the traveling gear. Automatically pays off the line when the device moves forward, and automatically takes up the line when the device moves backward. Of course, the speed of the take-up and pay-off line will match the walking speed of the device.

The hydraulic system 6 (see FIG. 10 ) includes two hydraulic pumps, two hydraulic motors, a large boom hydraulic cylinder part 34, a small boom hydraulic cylinder part 30, an oil receiver hydraulic cylinder 33, an obstacle removal support cylinder 23, and a left and right walking System and a number of electromagnetic reversing valves, one-way throttle valves, hydraulic control reversing valves, oil suction check valves, overflow valves, three-position four-way reversing valves, large boom hydraulic cylinder parts 34, and small boom hydraulic cylinders Component 30, oil collector hydraulic cylinder 33, and obstacle-clearing support cylinder 23 are each controlled by a three-position four-way reversing valve; Two traveling hydraulic motors with identical performance parameters, one pump supplies oil to one hydraulic motor independently.

For the convenience of turning, a parallel throttle valve and a two-position two-way electromagnetic reversing valve are respectively set up in the circuit.

1). Walk in a straight line

The synchronization of the hydraulic system 6, especially the synchronization of the small flow hydraulic system 6, is relatively difficult to realize with a hydraulic pump for oil supply. Considering that the device needs to turn due to road reasons during the walking process, a double hydraulic pump oil supply circuit is designed, and a double hydraulic gear pump with identical performance parameters and two walking hydraulic motors with identical performance parameters are selected. One gear pump is used independently. It supplies oil to a hydraulic motor, and at the same time, a parallel circuit of a throttle valve and a two-position two-way electromagnetic reversing valve is designed in the circuit. When the device is running normally, the electromagnets DT11 and DT12 of the two-position two-way electromagnetic reversing valve are not energized, and all the hydraulic oil pumped out by the hydraulic pump is directly supplied to the hydraulic motor. The two motors rotate at the same speed, and the device moves along a straight line.

2).Turning while walking

When the device needs to turn left, the electromagnet DT11 of the two-position two-way electromagnetic reversing valve in the oil supply circuit of the left motor is energized, and the non-resistance oil supply circuit is disconnected, and the hydraulic oil can only flow through the throttle valve to enter the motor without hydraulic resistance. Increase, a part of the hydraulic oil flows back to the oil tank through the electromagnetic unloading overflow valve at the outlet of the hydraulic pump. The rotation speed of the left motor is reduced, and the right motor moves at the original speed, so that the device turns left.

When the device needs to turn right, the electromagnet DT12 of the two-position two-way electromagnetic reversing valve of the right motor oil supply circuit is energized, and the non-resistance oil supply circuit is disconnected, and the hydraulic oil can only flow through the throttle valve connected in parallel with this solenoid valve Enter the motor, and realize the right turn of the device by decelerating the right drive motor.

The turning radius can be adjusted by adjusting the opening of the left and right throttle valves. The smaller the opening of the throttle valve, the smaller the turning radius.

3). Turn around the track

When the device needs to make a sharp turn due to road reasons or in the process of finding the pipe during the walking process, it can be realized by the three-position four-way electromagnetic reversing valve on the left and right.

For example: when it is necessary for the device to turn around the left track, the hydraulic valve electromagnets DT13 and DT14 are powered off, and the left motor stops rotating; the electromagnet DT15 or DT16 is powered on, and when the electromagnet DT15 is powered on, the right motor rotates forward, and the device goes around the left track Turn forward counterclockwise; when the electromagnet DT16 is energized, the right motor reverses, and the device turns clockwise around the left track.

4). Turn around the center of the device

When the device is close to the leaking oil injection port and the azimuth angle of the device needs to be adjusted on the spot, sometimes it needs to be rotated on the spot around the center of the device. The three-position four-way electromagnetic reversing valves on the left and right can cooperate with each other, so that one path advances and the other path retreats to realize local rotation. For example, when the hydraulic valve electromagnet DT13 is energized, the left motor rotates forward; when the hydraulic valve electromagnet DT16 is energized, the right motor reverses; the leakage control device rotates clockwise around the center. When the hydraulic valve electromagnet DT14 is energized, the left motor reverses; when the hydraulic valve electromagnet DT15 is energized, the right motor rotates forward; the leakage control device rotates counterclockwise around the center.

In order to control the speed of uphill and downhill and avoid the phenomenon of cavitation caused by the low oil inlet pressure of the motor when the device stalls, an oil suction check valve for oil replenishment is installed at the oil inlet and outlet of the motor to replenish oil when the motor is overspeed. The device has the requirement of going up and down during the walking process. When the device goes downhill, it may cause a stall due to the action of gravity. Therefore, a stall control is designed in the hydraulic system 6 . This function is accomplished by a parallel one-way throttle valve and a hydraulic control reversing valve connected to the oil inlet and outlet of the traveling motor. The oil enters the motor through the one-way valve, and at the same time, the pressure is switched back to the hydraulically controlled two-position two-way reversing valve in the oil circuit, and the return oil flowing out of the motor returns to the fuel tank through the reversing valve without resistance. When the device stalls downhill, because the motor speed is too fast, the oil supply flow of the hydraulic pump cannot meet the flow demand of the motor, so that the oil inlet pressure is too low, and the spring force of the reversing valve cuts off the oil return circuit. The oil returned from the motor can only be returned to the oil tank through the throttle valve, which increases the hydraulic resistance of the oil return, reduces the flow rate, reduces the speed of the device, and finally achieves the purpose of speed limit. The limited speed is also adjusted by adjusting the opening of the throttle valve.

In order to avoid the air suction caused by the low oil inlet pressure of the motor when the device stalls, resulting in cavitation and damage to the hydraulic motor, an oil suction check valve for oil replenishment is designed at the oil inlet and outlet of the motor in the system. Perform refueling.

In order to make full use of the power of the system, the high-low speed automatic switching function is set. Two motors are set in the low-speed high-torque motor, and the series-parallel conversion of the two motors is realized by controlling the oil. When the two motors are connected in series, the motor is in a high-speed low-torque running state; when the two motors are connected in parallel, the motor is in a low-speed high-torque running state. When the device is walking on flat ground or downhill, the driving power required by the device is small, and the output pressure of the hydraulic system is required to be low. By controlling the oil circuit to connect the two motors in series, the device can achieve high-speed walking; when the device is going uphill, due to the increase in resistance. Increased hydraulic system pressure. Use this pressure to switch the reversing valve of the traveling hydraulic motor to make the device realize low-speed walking.

In order to maintain the balance of the device, a climbing angle limiting circuit is designed in the system, and a relief valve is connected to the oil inlet of the motor as an overload valve. When the climbing angle of the device was too large, the pressure of the hydraulic system 6 was too high to make the oil flow away from the overload valve, and the device stopped moving, limiting the climbing angle of the device.

In view of the uncertain environmental conditions at the leakage port of the product oil pipeline, the oil collection angle of the oil receiver needs to be adjustable, and the stability of the device should be kept when the oil receiver goes down to collect oil. A three-position four-way reversing valve is set in the circuits of cylinder, small boom hydraulic cylinder, oil collection cover hydraulic cylinder, and rear support hydraulic cylinder to control the expansion and contraction of the oil cylinder, and a one-way throttle valve and overflow valve are connected to the oil inlet and outlet of the oil cylinder. flow valve.

In order to make the device work at night, an explosion-proof projection lamp 29 can be installed on the device.

The camera part 27 and the combustible gas detector are respectively connected to the cables retracted by the cable reel; the explosion-proof projection lamp 29 is directly connected to the power supply on the device.

1) The drive motor of the hydraulic pump uses a non-contact solid-state relay as the control element, which can avoid sparks generated due to the opening and closing of the contacts, which will become the source of ignition and detonation of the device. However, such a high-power solid-state relay requires forced ventilation to dissipate heat, and the use of a fan introduces another source of detonation. Considering comprehensively, the explosion-proof control box is adopted, and high-quality traditional motor control components are selected to control the start and stop of the motor;

Device explosion-proof

Explosion protection is the key to the device. According to the information checked, the explosion-proof performance of the device must be considered in the following aspects:

(1) Electrical control

The electrical control system is the weak link in the explosion-proof of the whole vehicle and the main source of electric sparks. Therefore, the electrical control system is the key to the explosion-proof performance of the equipment. In addition to the selection of explosion-proof motors and explosion-proof solenoid valves, in the design of electrical control systems, in accordance with relevant national standards, explosion-proof control components and explosion-proof control boxes that meet safety regulations must be selected.

The electrical control system is divided into a strong current control system and a weak current control system. The strong current control system mainly includes the start/stop control of the explosion-proof motor in the hydraulic system, the reversing control of the explosion-proof solenoid valve, the switch of the explosion-proof floodlight 29, etc.; the weak current control system mainly includes Including transmission and reception of remote control signals, various detection signals, transmission of video signals, etc.

1). Strong current control system

The strong current control system mainly pays attention to the following points:

① The start/stop of the main power motor and the cable reel, because the operating power is relatively large, the non-contact solid-state relay is selected, and the heat dissipation problem is not easy to solve. Therefore, it is necessary to select a flameproof control box that meets the use conditions and solve it through the control box Explosion-proof issues;

②The reversing electromagnet of the solenoid valve and the power of the floodlight are relatively small, and are controlled and protected by selecting non-contact semiconductor components-solid-state relays;

③The cable adopts armored cable to prevent the cable from rubbing against road stones or other sundries to damage the cable protective skin during the running of the device, so that the exposed wire will short-circuit and generate electric sparks.

2). Weak current control system

The weak current system mainly pays attention to the following aspects:

① The parameters are selected from intrinsically safe electrical control circuits, which can meet the explosion-proof requirements;

② Reasonable selection of electrical components, the current, voltage or power shall not be greater than 2/3 of its rated value, and shall not be greater than its rated value under fault conditions;

③Strictly follow the requirements of GB3836.4 "(Electrical Equipment for Explosive Gas Atmospheres Part Four: Intrinsically Safe Type "i"" for PCB design and circuit encapsulation, so that the creepage distance, electrical clearance and insulation parameters of the circuit And so on to meet the requirements of the national standard GB3836.

3). Explosion-proof communication system

The receiving antenna of the wireless communication module will generate radio frequency sparks. Choose a wireless transmitting and receiving module with a long transmission distance, and seal the communication module and antenna with non-metallic materials to prevent the generation of radio frequency sparks.

(2) Electrostatic discharge control

Since the generation of static electricity is unavoidable, it is inevitable that discharge and discharge will occur during the leakage control process. We can only work hard to control the amount of charge and the form of discharge, and control the static electricity within the range that does not cause harm.

1). Control the amount of oil collected so that the flow rate and flow rate of the collected oil meet the national regulations. The rest of the oil that cannot be recovered will flow to the ground after being reflected by the oil collector, so as to avoid the atomization of the oil to the greatest extent;

2). Reasonably design the structure of the oil collector of the leakage control device, so that the electrostatic discharge is controlled into a corona discharge; the corona discharge is continuous, and the discharge energy is relatively small, so that the oil-gas mixture will not be ignited; the specific method is to collect the oil A number of sharp peaks are made on the device, so as to achieve the purpose of controlling the discharge form;

3). The leakage control device is fully grounded, so that the electrostatic charge can be released quickly, so that the charge does not accumulate excessively; the whole device cannot be made into an insulator, and there are always conductors exposed to the oil-gas mixture; isolated and ungrounded conductors are the main cause of spark discharge The reason is to try to avoid the device as an isolated conductor and to make the leakage control device adequately grounded.

The device uses rubber crawlers, which are insulated from the ground, and the grounding of the device can only be achieved by cables. Choose 3*16+2*10 armored cables, and reserve one as a grounding cable to achieve reliable grounding of the device.

(3) mechanical system

So far, my country has not formulated explosion-proof standards for non-electrical equipment. At present, only the European non-electrical equipment explosion-proof standard EN13463 can be referred to. According to this standard, the factors for detonation and ignition of the device designed in this example are as follows: ① electrostatic discharge; ② damage to bearings or other metal parts; ③ hot surface.

1). Electrostatic discharge

Regarding the problem of electrostatic discharge, a more detailed description has been made earlier, and some necessary measures have been taken.

2). Bearings or other metal parts are damaged

Damaged bearings or other metal parts can generate sparks. Therefore, when choosing a bearing, it is necessary to fully consider the life and load capacity of the bearing, and consider a sufficient safety factor, so that the bearing capacity of the bearing far exceeds the actual load level, and the possibility of bearing damage is eliminated.

3).Hot surface

Hot surfaces are a factor in detonation ignition, and in the designed setup, the use of high-speed rotating pairs is avoided, thereby avoiding the creation of hot surfaces.

The leakage control device proposed by the utility model can realize oil leakage control under relatively high leakage pressure and improve the recovery rate of oil leakage. Since the operator performs remote control operations on the equipment at a certain distance from the leakage point, the safety of the emergency repair personnel is increased and the labor intensity is reduced.

The utility model solves the current problem of lack of appropriate control means after the high-pressure liquid leaks. The device proposed by the invention can greatly reduce the secondary disasters caused by the leak and recover the leaked fluid. At the same time, the utility model can also be used for leakage control of other types of pipelines and tanks.

1) According to the above parameters of the hydraulic motor, the working pressure of the hydraulic system is determined to be 20MPa, and the maximum pressure is 25Mpa;

2) The diameter of the indexing circle of the track drive wheel is 330mm, the walking speed is 2.4km/h, and the speed of the drive wheel is 38.6r/min;

Because the running speed of the leakage control device is not the main contradiction, the main thing is to control the power of the whole machine not to be too large, and to reduce the difficulty of power distribution as much as possible. Therefore, the maximum reduction ratio is selected as 53.7, the purpose is to obtain the maximum torque and the minimum speed.

The motor speed before deceleration is 2073r/min;

3) The flow rate of the oil supply pump is Q＝43.5 l/min. According to this parameter, select the hydraulic pump;

4) Hydraulic pump selection

According to the system operating conditions and parameter requirements, compare the performance characteristics of the hydraulic pump to determine the model of the hydraulic pump. Considering that the operating environment of the oil leakage control device is relatively harsh, the environmental pollution is relatively serious, the anti-pollution ability of the vane pump and the plunger pump are relatively weak, and high filtration accuracy is required, and finally it is decided to choose a high-pressure gear pump as the power component of the hydraulic system.

Among the actuators of this device, the walking motor requires the most power. Therefore, according to the parameters of the traveling motor and the actual situation of the total power of the device that this example can withstand, it is decided to choose the CBQL- F520/F520 double gear pump.

Double gear pump parameters:

Engineering displacement: 20/20mL/r;

Rated pressure: 20.0/20.0MPa;

Maximum pressure: 25.0/25.0MPa;

Speed range: 400-3000r/min;

Calculate the power according to the speed of 1500r/min and the pressure of 20.0MPa

N=20KW

(2). Motor selection

According to the parameters of the hydraulic pump, choose the ABB explosion-proof motor.

The main parameters:

Rated speed: 1500r/min;

Rated power: 22KW

Rated voltage: 380V

(3). Reverse checking and determining the walking speed of the device

1) walking speed

Single pump flow: 30L/min

There are two independent motors inside the special travel motor for hydraulic excavators. The realization of the high and low speeds of the hydraulic motor is realized by the series and parallel connection of the two internal independent motors. When two motors are connected in series, the relationship between high output speed and small torque is 2 times and 1/2 of each other, and the output power remains unchanged. The maximum stroke volume given by the hydraulic travel motor is the single-rotation displacement when two motors are connected in parallel.

The actual low speed speed of the motor: 1429r/min

Motor actual high speed speed: 2858r/min

Calculated according to the maximum reduction ratio of 53.7, the actual output speed of the deceleration motor after deceleration:

Low speed speed: 26.6r/min

High speed speed: 53.2r/min

Device walking speed:

Low speed: 1.656km/h

High speed: 3.312km/h

Average speed: 2.484km/h

The rotational speed meets the requirements of the initial design value of 2.4km/h in this example.

2) climbing ability

坡可以驱动的装置总重量climb

The total weight of the device that Poe can drive

Actual output power of a single hydraulic motor: 11192N m/s

Dual motor climbing drive power: 22.384kw

Total weight of the driven unit: 11.947 tons

Considering the total efficiency of the hydraulic system 6 and the mechanical system at 65%, the total weight of the driven unit is: 7.766 tons

In the case of explosion-proof environment, the allowable power of the motor should not exceed 70% of the power of the motor, which is limited by controlling the working pressure of the hydraulic system. The total weight of the device that can actually be driven is: 5.44 tons

的坡。When the total weight of the device does not exceed 5.44 tons, the device can climb

the slope.

The whole device includes two traveling hydraulic motors and four hydraulic cylinders. The hydraulic cylinder drives the large and small arms to swing to complete the up and down movement of the oil collector, and the hydraulic cylinder extends to realize the supporting function of the supporting parts. Two separately controlled walking hydraulic motors complete the forward, backward, turning and other work of the device.

Among the multiple actions of the device, climbing and walking consumes the most power. Therefore, the maximum power of the whole machine is calculated according to the situation of climbing and walking to determine the selection of hydraulic components.

5. Find the tube and locate it (remote control system 11, monitoring system 5)

(1). Mechanical and hydraulic

Due to the damage of the refined oil delivery pipeline, gasoline and kerosene are sprayed at high speed, creating a flammable and explosive environment around the fuel injection port. It is necessary for maintenance and emergency repair operators to remotely control the device to control and recover the sprayed oil. In view of factors such as cable retraction and transportation, the remote control distance of this device is 300 meters.

Due to the uncertain environmental conditions at the oil pipeline leakage outlet, including the angle of fuel injection, the ground conditions around the injection outlet, etc. Therefore, the oil collection angle of the oil leakage recovery device 1 is required to be adjustable. In order to meet the angle adjustment requirements of the oil spill recovery device 1, the device is designed with three rotating pairs of the large boom 3, the small boom 2, and the oil collector. The large boom 3 and the small boom 2 rotate in coordination with each other to adjust The front and rear positions of the oil spill recovery device 1 move the oil collector to the oil injection port; the orientation and angle of the oil spill recovery device 1 can be adjusted by rotating the rotating pair of the oil receiver, so that the axis of the oil spill recovery device 1 is in line with the injection port. The direction of oil flow is nearly the same. When the oil leakage recovery device 1 goes down to collect oil, the sprayed oil flow will generate an upward jet force on the oil leakage recovery device 1, which tends to turn the device backwards. In order to stabilize the device, the obstacle removal support system 8 is designed. These four components rely on the three-position four-way reversing valve to control the expansion and contraction of the oil cylinder, so as to realize the upward and downward movement or rotation of the oil collector. A one-way throttle valve and an overflow valve are connected at the oil inlet and outlet of the oil cylinder. The one-way throttle valve is used to limit the downward speed of each component, so that the downward movement of the components will not be too fast, so as to ensure the stability and safety of the device. The overflow valve connected to the oil port is used as an overload valve. When the injection force is too large, it limits the continuous movement of the moving parts that drive the oil receiver to avoid damage to the device.

(2).Remote control monitoring system

In order to be able to see the road conditions clearly when the leakage control device is walking, so as to be able to correctly choose the walking route; , injection direction, road or ground conditions near the injection port, etc.), 4 camera parts 27 are set, wherein: 1 camera part 27 is installed and fixed on the large boom 3, and is mainly responsible for observing the situation of the injection port; 2 cameras Components 27 are installed and fixed on both sides of the device respectively, and are used to observe the road conditions, so that the operator can choose the best walking route; a camera component 27 is installed on the top of the device, and the direction is backward, and it is used to observe the road conditions when reversing.

In this example, the BSJ-2A explosion-proof intrinsically safe color camera produced by Fuxin Double Star Electronics Co., Ltd. is selected, and the explosion-proof grade is exd II BT6.

In order to make the device work at night, an explosion-proof projection lamp 29 is installed on the device. The explosion-proof floodlights produced by Hangzhou Xianghua Explosion-proof Electric Appliance Co., Ltd., BSD4 series square explosion-proof floodlights are selected. It has high-pressure mercury lamps, high-pressure sodium lamps and metal halide lamps. Among them, metal halide lamps have the strongest ability to penetrate fog. Therefore, In this example, the metal halide lamp is selected as the lighting fixture, and the light projection range is .

1) The output power of the drive motor of the hydraulic pump is 22KW, and the non-contact solid state relay is selected as the control element, which can avoid sparks caused by the opening and closing of the contacts, which will become the source of ignition and detonation of the device. However, such a high-power solid-state relay requires forced ventilation to dissipate heat, and the use of a fan introduces another source of detonation. After comprehensive consideration, it was decided to choose an explosion-proof control box and high-quality traditional motor control components to control the start and stop of the motor. After investigation, Nanyang Explosion-Proof Electric Research Institute has strong technical force and considerable authority in electrical explosion-proof technology. It was decided to choose the BXK54 series explosion-proof electrical control box produced by Nanyang Explosion-Proof Electric Research Institute.

The finished product After being received by the wireless receiving device on the oil pipeline leakage control device, the single-chip microcomputer performs decoding processing and controls it. These electrical components require low driving power and are controlled by a single-chip microcomputer. The signal output by the single-chip microcomputer can directly control the solid-state relay without amplification. Therefore, the solid-state relay is most suitable for this occasion. The selected solid-state relays have a current of 5A and below without cooling.

3) An industrial control computer with anti-shock function is installed in the computer cabinet, which is used to encode the instructions issued by the operator through the buttons and transmit them to the wireless transmission module; receive the video signal of the remote control camera, and control the channel of the camera to switch.

9. Device explosion-proof

Explosion protection is the key to the device. According to the information checked, the explosion-proof performance of the device has been considered in the following aspects:

(1) Electrical control

The electrical control system is the weak link in the explosion-proof of the whole vehicle and the main source of electric sparks. Therefore, the design of the electrical control system is the key to the explosion-proof performance of the equipment. In addition to selecting explosion-proof motors and explosion-proof solenoid valves, in the design of electrical control systems, according to relevant national standards, select explosion-proof control components and explosion-proof control boxes that meet safety regulations.

The electrical control system is divided into a strong current control system and a weak current control system. The strong current control system mainly includes the start/stop control of the explosion-proof motor of the hydraulic system, the reversing control of the explosion-proof solenoid valve, the switch of the explosion-proof floodlight, etc.; the weak current control system mainly includes Transmission and reception of remote control signals, various detection signals, transmission of video signals, etc.

1). Strong current control system

The design of the strong current control system mainly considers the following points:

① The start/stop of the main power motor and the cable reel, because the operating power is relatively large, the solid state relay without electric shock is selected, and the heat dissipation problem is not easy to solve. Therefore, the explosion-proof control box that meets the use conditions is selected to solve the explosion-proof problem through the control box ;

②The reversing electromagnet of the solenoid valve and the power of the floodlight are relatively small, and are controlled and protected by selecting non-contact semiconductor components-solid-state relays;

③The cable adopts armored cable to prevent the cable from rubbing against road stones or other sundries to damage the cable protective skin during the running of the device, so that the exposed wire will short-circuit and generate electric sparks.

2). Weak current control system

The weak current system design considers the following aspects:

① The parameters are selected from intrinsically safe electrical control circuits, which can meet the explosion-proof requirements;

② Reasonable selection of electrical components, the current, voltage or power shall not be greater than 2/3 of its rated value, and shall not be greater than its rated value under fault conditions;

③Strictly follow the requirements of GB3836.4 "Electrical Equipment for Explosive Gas Atmospheres Part IV: Intrinsically Safe Type "i"" to design the PCB board and seal the circuit, so that the creepage distance, electrical clearance, insulation parameters, etc. of the circuit Meet the requirements of the national standard GB3836.

3). Explosion-proof communication system

The receiving antenna of the wireless communication module will generate radio frequency sparks. Choose a wireless transmitting and receiving module with a long transmission distance, and seal the communication module and antenna with non-metallic materials to prevent the generation of radio frequency sparks.

(2) Electrostatic discharge control

Since the generation of static electricity is unavoidable, it is inevitable that discharge and discharge will occur during the leakage control process. We can only work hard to control the amount of charge and the form of discharge, and control the static electricity within the range that does not cause harm.

1). Control the amount of oil collected so that the flow rate and flow rate of the collected oil meet the national regulations. The rest of the oil that cannot be recovered will flow to the ground after being reflected by the oil collector, so as to avoid the atomization of the oil to the greatest extent;

2). Reasonably design the structure of the oil collector of the leakage control device, so that the electrostatic discharge is controlled into a corona discharge; the corona discharge is continuous, and the discharge energy is relatively small, so that the oil-gas mixture will not be ignited; the specific method is to collect the oil A number of sharp peaks are made on the device, so as to achieve the purpose of controlling the discharge form;

3). The leakage control device is fully grounded, so that the electrostatic charge can be released quickly, so that the charge does not accumulate excessively; the whole device cannot be made into an insulator, and there are always conductors exposed to the oil-gas mixture; isolated and ungrounded conductors are the main cause of spark discharge The reason is to try to avoid the device as an isolated conductor and to make the leakage control device adequately grounded.

The device uses rubber crawlers, which are insulated from the ground, and the grounding of the device can only be achieved by cables. Choose 3*16+2*10 armored cables, and reserve one as a grounding cable to achieve reliable grounding of the device.

(3) mechanical system

So far, my country has not formulated explosion-proof standards for non-electrical equipment. At present, only the European non-electrical equipment explosion-proof standard EN13463 can be referred to. According to this standard, the factors for detonation and ignition of the device designed in this example are as follows: ① electrostatic discharge; ② damage to bearings or other metal parts; ③ hot surface.

1). Electrostatic discharge

Regarding the problem of electrostatic discharge, a more detailed description has been made earlier, and some necessary measures have been taken.

2). Bearings or other metal parts are damaged

Damaged bearings or other metal parts can generate sparks. Therefore, when choosing a bearing, it is necessary to fully consider the life and load capacity of the bearing, and consider a sufficient safety factor, so that the bearing capacity of the bearing far exceeds the actual load level, and the possibility of bearing damage is eliminated.

3).Hot surface

Hot surfaces are a factor in detonation ignition, and in the designed setup, the use of high-speed rotating pairs is avoided, thereby avoiding the creation of hot surfaces. After checking, the rotating pair in the device makes the temperature increase of the device insignificant when it is working.
