Description

Oil and air bag combined floating platform

【Technical field】

The utility model relates to an underwater floating lifting device, in particular to an oil-air bag combined floating platform.

【Background technique】

At present, domestic and foreign submersible buoy systems (underwater platform systems) generally work in water by using mooring anchors to tie the submersible buoy (also known as the main buoy) to a certain depth in the water, and then mooring the surface buoy to the bottom of the water. The submersible floats on the water surface for a long time; in this way, an underwater communication link and a submersible system are formed, and the underwater environmental information collected by the submersible is transmitted to the outside world through this communication link. However, this working method has its limitations. It can only carry out environmental monitoring at fixed-point locations, and the monitoring range is very limited. Moreover, buoys floating on the water surface for a long time are easily damaged due to sea wind waves, tides, long-term sunlight exposure, different seasons and the influence of day and night temperature changes, and human factors. Usually, considerable manpower and ships are required to monitor or Inspection and maintenance costs are considerable.

【Content of invention】

The purpose of this utility model is to solve the problems existing in the above-mentioned submersible buoy system, and propose an oil-air bag combined floating platform device, which integrates the independent functions of the submersible buoy and the water surface buoy, and can be controlled according to the control instructions (the shore station passes Satellite control) automatically floats and lifts within the range from a certain depth underwater to the water surface, and transmits various marine environmental information monitored in this sea area to the outside world through the lifting function of the device.

The purpose of this utility model is achieved in this way: an oil-air bag combined floating platform is composed of a platform body 1, a buoyancy adjustment device and a control system 2, a hydraulic system 3, an air pressure system 4 and a control system 2 are installed in the platform body, and the platform The upper part of the body is equipped with a buoyancy adjustment device, the buoyancy adjustment device includes an annular oil bag 5 and an air bag 6 combination bag, the oil bag 5 is installed in the air bag 6, the oil bag is connected with the hydraulic system 3 through the oil pipe 7, and the air bag 6 is connected with the air pressure system through the air pipe 8 4 connection, the upper end of the platform body is provided with a connection interface that matches the installation size of the transceiver device.

In the above oil-air bag combined floating platform, a shield 9 is installed on the periphery of the oil bag and air bag combination bag, and the outer diameter of the shield 9 is consistent with the outer diameter of the platform.

Due to the adoption of the above structure, the oil bag or air bag is opened according to different water depths, and the buoyancy of the system is adjusted by controlling the filling and discharging of the oil bag and air bag, so that the platform floats or rises and falls according to the control command, so the utility model has the advantages of not needing personnel to guard , good concealment, strong maneuverability, etc., and because it floats underwater for a long time (only emerges from the water to transmit information within the set time), it avoids the buoys being easily damaged by various natural and human factors in the past.

【Specific implementation method】

An oil-air bag combined floating platform, consisting of a platform body 1, a buoyancy adjustment device and a control system 2, the platform body is an upright platform with small negative buoyancy (provided by a counterweight), a hydraulic system 3, a pneumatic system 4 and a control system 2 Installed in the platform body, a buoyancy adjustment device is installed on the upper part of the platform body. The buoyancy adjustment device includes an annular oil bag 5 and an air bag 6 combination bag. The air pipe 8 is connected to the air pressure system 4. The hydraulic system includes a fuel tank, a DC motor oil pump group, an oil circuit electromagnetic reversing valve, an overflow valve, a fuel tank pressure balance valve and related oil circuits. The air pressure system includes an air tank, a DC motor air pump group, and a gas An electromagnetic reversing valve, an overflow valve and related air circuits, and a connection interface matching the installation size of the transceiver device is provided on the upper end of the platform body, and various types of transceiver devices 10 can be connected externally. When the oil bag and the combined bag of the air bag are inflated, the maximum is no more than the column diameter of the platform. For protecting the combined bag, a shield 9 is installed on the periphery of the combined bag, and the outer diameter of the shield is consistent with the outer diameter of the platform.

When in use, first place the device into the water. The device sinks continuously by its own small negative buoyancy, and the deepest can be controlled at a water depth of 200m. The system automatically adjusts to zero buoyancy through the oil-air bag buoyancy adjustment device, and floats in the water.

When the control system gives the floating command according to the set control program, start the DC motor oil pump group of the hydraulic system (the motor is rotating forward at this time), and open the electromagnetic reversing oil valve at the same time to continuously inject the hydraulic oil from the oil tank into the oil bag. Make the oil sac gradually expand. Due to the additional volume generated by the expansion of the oil bag, the floating platform device continues to float up. When the additional volume reaches the set value, the control system gives a control command, the DC motor oil pump unit stops, the electromagnetic reversing oil valve is closed, and the expansion volume of the oil bag is reduced. locking. When the floating platform device floats to a water depth of about 50m from the water surface, the control system gives a control command to open the electromagnetic reversing air valve, and the high-pressure gas in the air tank is injected into the air bag, and the air bag expands rapidly, so that the floating platform device quickly floats to the water surface. The transceiver cabin is exposed above the water surface, and at this moment, information can be transmitted and received to the outside world.

When the sinking command is given, start the DC motor oil pump group of the hydraulic system (the motor is reversed at this time), and at the same time open the electromagnetic reversing oil valve to continuously pump the hydraulic oil in the oil bag into the oil tank, so that the volume of the oil bag gradually increases. zoom out. At the same time, start the DC motor air pump group to pump the gas in the air bag into the air box. At this time, the floating platform device continues to sink until the set water depth. The system automatically adjusts to zero buoyancy through the oil-air bag buoyancy adjustment device, and closes the motor and all valves to lock the volume of the oil-air bag so that the floating platform device floats in the water. The monitoring equipment monitors the marine environment and collects and reserves information, while waiting for the next lifting and lowering cycle.
