A gas-fired underwater attitude change floating device with anti-surge disturbance

Abstract

The invention discloses a gas-consuming underwater posture changing upward-floating device resisting surges. When the device needs to float upwards to the water surface for work, a relay controls an electricity supply pipeline to electrify a fuel gas agent pillar inside an air cylinder gas generator, the fuel gas agent pillar is combusted to generate high-pressure gas, the high-pressure gas entersthe bottom of a multi-stage pneumatic cylinder, the multi-stage telescopic pneumatic cylinder is pushed to quickly stretch to drive a balance weight to be away from a carrier, and the position of thecenter of gravity of the carrier is changed; after a preset time is delayed, the relay controls a gasbag gas generator to be electrified, a fuel gas agent pillar inside the generator is combusted togenerate high-pressure slow-release gas, a compressed buoyancy gasbag is inflated to be quickly expanded, the wetted area of the carrier is increased, and extra buoyancy is generated to change the position of the buoyant center. Under the joint effect of gravity and buoyancy, the carrier rotates under the change of torque of itself, and the posture of the carrier is changed into the vertical state, so that the carrier quickly floats upwards to the sea level. By means of the gas-consuming underwater posture changing upward-floating device resisting the surges, the carriers can carry different water surfaces, and the gas-consuming underwater posture changing upward-floating device has the advantages of being simple in structure, convenient to control, reliable in work, small in size, wide inadaptive surface, convenient to use and the like.

Description

technical field [0001] The invention relates to an underwater floating device, in particular to a gas-fired underwater posture-changing floating device resistant to surge disturbance. Background technique [0002] Surface detection devices, especially the miniaturized buoys used for relay communication and detection in the ocean environment, need to have the function of adjusting the center of gravity of the structure when they work normally under the condition of surge disturbance. Adjust the overall center of gravity position of the mechanism through the counterweight structure to ensure that the detector is always in the "upright" state relative to the water surface. The impact of surge disturbance on the performance of the detection device can be improved, and the overall stability and adaptability of the detection device can be improved. [0003] At present, the main method adopted for marine product equipment is to set the structural counterweight in the lower part of...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the water surface detection device (buoy) does not have the ability to adjust the center of gravity in a wide range, it is difficult to maintain the basic "upright" state under the disturbance of the sea surface surge, and it cannot be carried by underwater vehicles for release, concealment Poor performance and high cost
