Background Art

A photovoltaic power station refers to a power generation system that utilizes solar energy and is composed of photovoltaic panels, inverters and other electronic components. The current generated by the photovoltaic panels when receiving light needs to be transmitted through cables. Therefore, in the construction of a photovoltaic power station, a cable laying device is indispensable. For this purpose, a cable laying device based on direct buried cables is proposed.

The Chinese invention application patent with publication number CN116914632A discloses an auxiliary device for direct buried laying of power cables, including a first crossbeam, at least two slides are arranged on the first crossbeam, a rotating frame is arranged above the slide, and a guide wheel assembly for supporting the cable is detachably arranged between the slide and the rotating frame, the guide wheel assembly includes a rotating shaft, a support wheel is fixedly connected to the rotating shaft, and a channel for diverting fine sand is arranged below the guide wheel member and inside the slide.

In this technical solution, although fine sand can be filled after the cables are laid, the laying requirements of direct buried cables require not only the laying of fine sand but also the use of concrete slabs (or bricks) to cover the cables after filling with fine sand to ensure the protection of the cables.

DETAILED DESCRIPTION

The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

In conjunction with FIGS. 1 to 9 , an embodiment of the present invention provides a cable laying device for a photovoltaic power station, including:

A first connecting seat 101 and a second connecting seat 102, wherein brake wheels 103 are disposed at four corners of the bottom of the first connecting seat 101 and the second connecting seat 102, and the first connecting seat 101 is a frame-type structure;

Two power assemblies, the two power assemblies are arranged on both sides of the second connecting seat 102, and the two power assemblies are fixed to the first connecting seat 101, and the power assemblies adjust the distance between the first connecting seat 101 and the second connecting seat 102;

A wire-laying assembly, a sand-filling assembly and a laying assembly, wherein the wire-laying assembly is arranged on the top of the second connection seat 102, the sand-filling assembly and the laying assembly are arranged on the top of the first connection seat 101, the sand-filling assembly is used to fill fine sand into the cable trench, the laying assembly is used to lay a concrete slab in the cable trench, and the sand-filling assembly is arranged between the wire-laying assembly and the laying assembly;

Two mounting blocks 401, the two mounting blocks 401 are respectively fixed to the first connecting seat 101 and the second connecting seat 102, and the two mounting blocks 401 are both provided with lifting components;

A laying component, which is connected to the two lifting components and is used for laying cables;

The single chip microcomputer is electrically connected to the sand filling assembly, the two power assemblies and each brake wheel 103 through a signal line.

By controlling the state of the brake wheel 103, the first connection seat 101 and the second connection seat 102 can be moved, or the first connection seat 101 and the second connection seat 102 can be in a fixed state. When the first connection seat 101 is in a fixed state and the second connection seat 102 can be moved, the second connection seat 102 can be moved forward by the operation of the power assembly, that is, the first connection seat 101 and the second connection seat 102 are separated. Conversely, the state of the brake wheel 103 on the first connection seat 101 and the second connection seat 102 is changed. When the first connection seat 101 is movable and the second connection seat 102 is in a fixed state, during the operation of the power assembly, the first connection seat 101 moves and moves closer to the second connection seat 102.

By controlling the length of the concrete slab and the stroke of the power assembly, the first connecting seat 101 moves a distance of the length of the concrete slab each time, so that when laying the concrete slab, there is no need to position the concrete slab, and the concrete slab can be laid in a state of being connected end to end, so as to quickly complete the covering work of the concrete slab;

It is worth noting that the braking effect of the brake wheel 103 comes from the hydraulic disc brake, so the brake wheel 103 is a prior art. In addition, the line connection and control logic between the microcontroller and the power parts of the hydraulic disc brake are also prior art, so this application will not go into details.

Furthermore, the power assembly includes:

A first fixing block 201 and a second fixing block 203, wherein the first fixing block 201 is fixed on a side wall of the first connecting seat 101, and the second fixing block 203 is fixed on a side wall of the second connecting seat 102;

Further, the laying components include:

Two electric slides 601, both of which are fixed on the top of the first connecting seat 101, the same conveying seat 602 is fixed on the moving ends of the two electric slides 601, the conveying seat 602 is used to place the concrete slab, and a plurality of balls 603 are rotatably arranged on the top of the conveying seat 602, and both of the two electric slides 601 are electrically connected to the single-chip microcomputer;

Four positioning units, which are arranged at four sides of the top of the conveying seat 602;

A support frame 701, the support frame 701 is fixed on the top of the first connecting seat 101;

A second hydraulic push rod 704, which is fixed on the top of the support frame 701, and a mounting seat 705 is provided at the output end of the second hydraulic push rod 704, and the second hydraulic push rod 704 is electrically connected to the single chip microcomputer;

Two vacuum suction cups 706, both of which are fixed at the bottom of the mounting seat 705;

The switch of the second hydraulic push rod 704 is turned on. When the second hydraulic push rod 704 is working, it drives the mounting seat 705 and the vacuum suction cup 706 on the mounting seat 705 to descend. When the vacuum suction cup 706 contacts the concrete slab, the switch of the vacuum pump is turned on. When the vacuum pump is working, the vacuum suction cup 706 is in a vacuum state through the three-way hose 703 to achieve the fixing of the concrete slab. Then, the second hydraulic push rod 704, the mounting seat 705 and the vacuum suction cup 706 can be used to achieve the descent of the concrete slab and place the concrete slab in the cable trench.

In the above process, the conveying seat 602 is driven to move by the operation of the electric slide 601 to complete the conveying of the concrete slab. In addition, when laying the concrete slab, the conveying seat 602 is driven away from the first connecting seat 101 by the electric slide 601, thereby avoiding the conveying seat 602 from obstructing the laying of the concrete slab.

Furthermore, the positioning unit includes:

Support plate 604, support plate 604 is fixed on the conveying seat 602;

The second electric push rod 605 is arranged on the side wall of the support plate 604 through the second electric push rod 605, and a push plate 606 is fixed to the telescopic end of the second electric push rod 605. The second electric push rod 605 is electrically connected to the single chip microcomputer.

Turn on the switches of the two second electric push rods 605 in the longitudinal direction of the conveying seat 602, and make the two second electric push rods 605 extend to the same length. In this process, the concrete slab can be moved more easily on the conveying seat 602 through the rolling of the ball 603. The concrete slab is pushed by the second electric push rods 605 and the push plate 606 to preliminarily adjust the position of the concrete slab on the conveying seat 602. Similarly, when the switches of the two horizontal support plates 604 on the conveying seat 602 are turned on, the position adjustment of the concrete slab on the conveying seat 602 is completed, so that the concrete slab is in the center of the conveying seat 602.

Further, the pay-off assembly includes:

Two pay-off frames 301, both of which are fixed on the top of the second connecting seat 102, and both of which have round holes on their side walls, into which the same support shaft 302 is inserted;

Furthermore, the support assembly includes:

The connecting block 310 is disposed on the end of the rod body 305 , and the connecting block 310 and the guide frame 303 are rotatably connected.

Lift the cable drum and move it between the two pay-off frames 301, insert the support shaft 302 into the round hole on one of the pay-off frames 301, pass through the cable drum and then pass through the round hole on the other pay-off frame 301, and rotate the support shaft 302 and the pay-off frame 301 to make the cable drum rotate, thereby releasing the cable;

When the cable drum is stuck during the process of releasing the cable, the force generated by the traction of the cable acts on the rotating shaft 306 through the first pulley 308 and the mounting frame 307, thereby causing the guide frame 303 to rotate. Since the first spring 309 can be compressed, the rod body 305 can be pressed into the cylinder body 304, thereby preventing the cable from being damaged due to excessive tension during the laying process.

Further, the sand filling assembly comprises:

A sand storage box 501 is fixed on the top of the first connecting seat 101, and a cover 502 is hinged on the top of the sand storage box 501;

The second spring 408 has one end fixed to the piston 407 and the other end fixed to the inner wall of the sleeve 402 .

Furthermore, it also includes:

The connecting hose 404 has two ends that pass through the top inner walls of the two sleeves 402 respectively.

Turn on the switch of the air pump and close the switch of the solenoid valve 409 at the same time. When the air pump is working, gas is injected into the sleeve 402 near the first connecting seat 101 through the air supply pipe 410, pushing the piston 407 in the sleeve 402 to descend, thereby causing the corresponding sleeve rod 403 to descend, and through the connecting hose 404, the sleeve rod 403 near the second connecting seat 102 also descends.

Further, the laying assembly includes:

A connecting frame 405, the connecting frame 405 is fixed to the bottom of the sleeve rod 403 near the second connecting seat 102, and a plurality of evenly distributed second pulleys 406 are rotatably arranged on the side wall of the connecting frame 405, and the plurality of second pulleys 406 correspond to the plurality of first pulleys 308 one by one;

The connecting plate 412 is fixed to the bottom of the sleeve rod 403 near the first connecting seat 101. A plurality of rubber blocks 413 are arranged at the bottom of the connecting plate 412. The bottom end height of the rubber block 413 is lower than the bottom end of the connecting frame 405. The plurality of rubber blocks 413 correspond to the plurality of second pulleys 406 one by one. A semicircular notch is provided at the bottom of each rubber block 413.

When one of the sleeve rods 403 descends, it drives the connecting plate 412 to descend, so that the rubber block 413 on the connecting plate 412 contacts the cable, and the cable is fixed in the cable trench by the squeezing of the rubber block 413. When one of the sleeve rods 403 descends, it drives the connecting frame 405 to descend. Since the bottom end height of the rubber block 413 is lower than the bottom end of the connecting frame 405, after the rubber block 413 fixes the cable to the bottom of the cable trench, the connecting frame 405 and the second pulley 406 on the connecting frame 405 do not contact the fine sand at the bottom of the cable trench, so that the fine sand filled at the bottom of the cable trench will not be damaged during the movement of the second pulley 406. In addition, since the second pulley 406 is in the cable trench, the cable can be directly laid at the bottom of the cable trench during the cable laying process. Therefore, after the second pulley 406 rises, the cable is still in a stationary state, avoiding the change of the cable position caused by the cable falling, and thus facilitating the subsequent rubber block 413 to fix the cable again.

The specific working method is: after the cable trench is excavated, fine sand is spread on the bottom of the trench, then the length of the concrete slab is measured, the length value of the concrete slab is recorded, and the data is input into the single chip computer, and finally according to the diameter of the cable to be laid, a suitable rubber block 413 is selected, that is, the diameter of the semicircular notch of the rubber block 413 should be the same as the diameter of the cable, so that when the cable is in the semicircular notch of the rubber block 413, the cable is in close contact with the rubber block 413 and the cable is squeezed on the fine sand at the bottom of the cable trench, and then the device can be used to lay the cable;

When in use, first lift the cable drum, then move the cable drum to between the two pay-off frames 301, insert the support shaft 302 into the round hole on one of the pay-off frames 301, pass through the cable drum and then pass through the round hole on the other pay-off frame 301, then install shaft retaining rings at both ends of the support shaft 302 to prevent the support shaft 302 from falling off the pay-off frame 301, then fix the support shaft 302 and the cable drum, and then ensure that the support shaft 302 can rotate in the round hole on the pay-off frame 301, so that the cable drum can rotate, so that the cable drum can release the cable, open the cover 502, and fill the sand storage box 501 with dry fine sand;

Then, the cable end on the cable drum is pulled out, and the cable is passed through the surfaces of the first pulley 308 and the second pulley 406 in sequence, and finally the cable end is placed under the rubber block 413. Since the first pulley 308, the second pulley 406 and the rubber block 413 are equidistantly distributed and correspond one to one, the cable can be laid in the cable trench at a suitable spacing. At this time, the single-chip microcomputer works, the single-chip microcomputer turns on the switch of the air pump, and turns off the switch of the solenoid valve 409. When the air pump works, gas is injected into the sleeve 402 near the first connecting seat 101 through the air supply pipe 410, pushing the piston 407 in the sleeve 402 to descend, and then the connecting plate 412 is descended through the corresponding sleeve rod 403, so that the rubber block 413 on the connecting plate 412 contacts the cable, and the rubber block 413 squeezes the cable, so that the cable The cable is fixed in the cable trench. During this process, the second spring 408 is compressed, and the two sleeves 402 are connected through the connecting hose 404. Then, under the action of the corresponding piston 407, the sleeve rod 403 close to the second connecting seat 102 is also lowered, and the connecting frame 405 on the sleeve rod 403 is lowered accordingly. Since the bottom end height of the rubber block 413 is lower than the bottom end of the connecting frame 405, when the rubber block 413 fixes the cable at the bottom of the cable trench, the connecting frame 405 and the second pulley 406 on the connecting frame 405 are not in contact with the fine sand at the bottom of the cable trench. After the cable is fixed, the single-chip microcomputer records the value of the air pressure sensor. In the subsequent working process, when the cable is fixed, the single-chip microcomputer controls the air pump to work so that the air pressure in the sleeve 402 reaches this value, which can be regarded as the completion of the cable fixing.

The single chip controls the brake wheel 103 on the first connecting seat 101 to lock, and enables the brake wheel 103 on the second connecting seat 102 to rotate normally, and then turns on the switch of the first hydraulic push rod 202. Subsequently, the single chip adjusts the stroke of the first hydraulic push rod 202 according to the length of the concrete slab. When the first hydraulic push rod 202 is working, the first connecting seat 101 and the second connecting seat 102 are moved away from each other through the first fixed block 201 and the second fixed block 203. Since the brake wheel 103 on the first connecting seat 101 is locked, the first connecting seat 101 is fixed, and the second connecting seat 102 moves forward, and the moving distance is the length of the concrete slab.

During the movement of the second connection seat 102, since the end of the cable is fixed in the cable trench by the rubber block 413, the cable drum is rotated by pulling the cable, that is, the cable drum releases the cable. In this process, the second pulley 406 is used to limit the position of the cable in the cable trench during the laying process, and the cable is close to the fine sand at the bottom of the cable trench.

The first spring 309 cooperates with the rod 305 and the connecting block 310 to support the guide frame 303. Therefore, the cable can be tensioned during the process of releasing the cable, which prevents the cable from being too loose after laying. When the cable drum is stuck during the process of releasing the cable, the force generated by the cable being pulled acts on the rotating shaft 306 through the first pulley 308 and the mounting frame 307, thereby causing the guide frame 303 to rotate. Since the first spring 309 can be compressed, the rod 305 can be pressed into the cylinder 304, which prevents the cable from being damaged due to excessive tension during the laying process.

After the cable is laid, the single chip microcomputer turns on the switch of the solenoid valve 409, so that the gas in the sleeve 402 can be output through the solenoid valve 409, and then the piston 407 is reset under the action of the second spring 408, so that the rubber block 413 rises, and then the single chip microcomputer locks the brake wheel 103 on the second connecting seat 102, and releases the locking state of the brake wheel 103 on the first connecting seat 101, and then turns on the switch of the first hydraulic push rod 202, so that the first hydraulic push rod 202 shrinks. In this process, since the second connecting seat 102 is locked by the corresponding brake wheel 103, the first connecting seat 101 is gradually Gradually approaching the second connection seat 102, since the distance between the second connection seat 102 and the first connection seat 101 is the length of a concrete slab, the distance moved by the first connection seat 101 is also the length of a concrete slab. During the movement of the first connection seat 101, the single chip microcomputer turns on the switch of the first electric push rod 503. When the first electric push rod 503 is working, it drives the sealing plate 505 away from the output hole 506 through the transmission plate 504, so that the fine sand in the sand storage box 501 can be output from the output hole 506. Therefore, with the movement of the first connection seat 101, the fine sand can be covered on the laid cable;

After the first connecting seat 101 stops moving, that is, the first hydraulic push rod 202 stops working, the single chip microcomputer turns on the switch of the first electric push rod 503 again, so as to reset the sealing plate 505 through the transmission plate 504, thereby stopping the output of fine sand. Subsequently, the staff controls the single chip microcomputer to execute the concrete slab laying program. When the concrete slab laying work starts, the single chip microcomputer first turns on the switch of the electric slide 601. When the electric slide 601 works, it drives the conveying seat 602 to move, so that the conveying seat 602 is away from the first connecting seat 101, and then the concrete slab is placed on the top of the conveying seat 602 by using the lifting equipment. Then the single chip microcomputer turns on the switches of the two second electric push rods 605 on the longitudinal direction of the conveying seat 602, and makes these two second electric push rods 605 move. The electric push rods 605 extend to the same length. In this process, the concrete slab can be easily moved on the conveying seat 602 by the rolling of the ball 603. The concrete slab is pushed by the second electric push rod 605 and the push plate 606 to preliminarily adjust the position of the concrete slab on the conveying seat 602. Similarly, when the single-chip microcomputer turns on the switches of the two horizontal support plates 604 on the conveying seat 602, the position adjustment of the concrete slab on the conveying seat 602 is completed. Since the above four second electric push rods 605 are symmetrical in pairs, the push plate 606 on the second electric push rod 605 can prevent the concrete slab from deviating on the conveying seat 602, so that the concrete slab can be located at the center of the conveying seat 602 after the position is adjusted.

Then the single chip microcomputer controls the electric slide 601 to move the conveying seat 602 to the position directly below the second hydraulic push rod 704. Then the single chip microcomputer controls the second hydraulic push rod 704 to work. When the second hydraulic push rod 704 works, it drives the mounting seat 705 and the vacuum suction cup 706 on the mounting seat 705 to descend. When the vacuum suction cup 706 and the concrete slab collide, the single chip microcomputer turns on the switch of the vacuum pump. When the vacuum pump works, the vacuum suction cup 706 is in a vacuum state through the three-way hose 703 to achieve the fixing of the concrete slab. Then the single chip microcomputer uses the electric slide 601 to move the conveying seat 602 away from the first connecting rod 704. The first connecting seat 101 is connected to the second hydraulic push rod 704, the mounting seat 705 and the vacuum suction cup 706, and the concrete slab is lowered, and the concrete slab is placed in the cable trench, thereby realizing the laying, sand filling and covering of the cables. Since the moving distance of the first connecting seat 101 is the length of the concrete slab, and since the positions of the second hydraulic push rod 704 and the first connecting seat 101 are always kept relatively fixed, the second electric push rod 605 and the push plate 606 are used to position the concrete slab, so that each time the concrete slab is covered, there is no need to position the concrete slab, and the concrete slab can be covered in the cable trench in turn;

Repeat the above operations to complete the direct burial of the cable. Finally, backfill the soil into the cable trench and tamp it to complete all the cable laying work.
