Safety valve type underwater fixed-depth releasing device

Abstract

The invention aims to provide a safety valve type underwater fixed-depth releasing device, which comprises a filter, a safety valve and a releasing mechanism, wherein the filter is fixed at the water inlet of the safety valve; the water outlet of the safety valve is connected with the releasing mechanism; a tacking bolt is pressed against a bearing bar; the bearing bar is used for bearing pressure load on both sides; an adjusting screw cap can be moved up and down on the outer surface of a lower valve body through a screw thread, and the pressure of the safety valve can be adjusted by adjusting a pressure regulating spring; the adjusting screw cap is connected with the lower valve body through a screw thread, the adjusting screw cap and the lower valve body are sealed through a sealing ring, and a locking nut can be used for preventing the adjusting screw cap from rotating freely; an upper valve body is connected with a valve body interface through a taper thread and is wound with a thread seal tape for sealing; the valve body interface is sealed with an upper cover through a sealing ring, and an interface pressure plate is used for compressing the valve body interface onto the upper cover through a bolt; the sealing cover is used for performing end face static seal between the sealing ring and the upper cover, and limiting a steel ball from rolling outwards. The safety valve type underwater fixed-depth releasing device is high in loading bearing capacity, light in weight, small in size and easy to install.

Description

technical field [0001] The invention relates to an underwater robot, specifically an underwater release robot. Background technique [0002] With the rapid development of the modern world economy, energy consumption is also accelerating, and land resources are gradually becoming insufficient. More and more countries are focusing their development on the vast ocean. As the main force of deep sea development, the development of underwater robot technology is getting more and more attention. The operating environment of underwater robots is very harsh, especially for those deep-sea operating robots, they often face various dangers, such as being entangled in submarine cables, fishing nets, etc., colliding with submarine objects and other unpredictable external risk factors Risk factors caused by self-problems such as power or electrical system failure, water leakage in some pressure-resistant cabins, etc. If these risk factors cannot be dealt with and controlled effectively i...
