Underwater platform cable throwing device with buoy

Abstract

The invention relates to an underwater platform cable throwing device with a buoy. When the cable throwing device is in a non-triggered state, a bottom plate is attracted by an electromagnet assembly,and a cable and a buoy assembly are located in a cable storage cavity; when the buoy assembly needs to be taken back on a platform or released at the indication position, the electromagnet assembly instantly loses the restraint on the bottom plate, at the moment, a spring pushes a top plate to move in the axial direction of the cable storage cavity under the effect of resilience, and the cable and the buoy assembly are thrown out of the cable storage cavity. The buoy assembly and the cable are gradually spread in air and fall and float on water after being thrown out of the cable storage cavity, and a GPS and a beacon module in the buoy assembly send a position indication signal to a mother ship. By means of the cable throwing device, the problems of taking back, safety guaranteeing and positioning of various underwater platforms can be solved.

Description

technical field [0001] The invention relates to a cable throwing device, in particular to a cable throwing device for an underwater platform with a buoy, and belongs to the field of electromagnetic technology. Background technique [0002] With the breakthrough of various underwater platform technologies at home and abroad, all kinds of modern platforms are used in rivers, lakes, seas and water fields. With the influence of factors such as weather and hydrological characteristics, problems such as recovery of underwater platforms, safety assurance, positioning search and rescue have become prominent, and have once become worldwide difficulties. Technological breakthroughs are urgently needed to solve the above problems. The main problems of existing underwater platform cable throwing devices are: (1) when the underwater platform is inconvenient to float up, it cannot send position information to the mother ship; When unable to float successfully, the mother ship cannot conf...

AI Technical Summary

Problems solved by technology

The main problems of existing underwater platform cable throwing devices are: (1) when the underwater platform is inconvenient to float up, it cannot send position information to the mother ship; When it cannot be successfully floated, the mother ship cannot confirm its position, and rescue is difficult; (3) It is inconvenient to recover after the underwater platform floats to the water surface

Due to the complex structure, the trigger and release units are all disposable and need to be refilled and replaced, and there are certain shortcomings in operation, such as high cost and difficult maintenance.

And there is no related device that can meet various water depths and hydrological characteristics at the same time, and no equipment that meets the needs of underwater platforms for recovery, safety assurance, and positioning has not yet been found.
