An underwater power booster and exhaust device with waterproof backflow function

Abstract

An underwater power pressurization exhaust device with a water backflow resistant function comprises a carrying unit casing and a power system arranged in the carrying unit casing. An air feeding tube communicated with the atmosphere and an air exhaust tube are arranged on the power system, and an exhaust port is formed in the front end of the air exhaust tube. An air compressor for pressurizing exhausted gas is arranged in the carrying unit casing, and a pressurizing tube outlet of the air compressor is formed in the exhaust port. A check valve is arranged in the position in front of the pressurizing tube outlet in the air exhaust tube, and a water-proof valve is arranged between the check valve and the pressurizing tube outlet. A piston cylinder is arranged on one side of the water-proof valve, a piston connected with the water-proof valve is arranged in the piston cylinder, and the pressurizing tube is communicated with the piston cylinder. By means of the device, high-pressure air generated by the air compressor can be used for pushing the piston to move downwards vertically, and accordingly, the water-proof valve is opened and closed, and the power system exhausts waste gas. When the air compressor stops operating, the piston moves upwards vertically under the action of seawater pressure, buoyancy and a spring to enable the water-proof valve to be closed, and accordingly, outside seawater cannot flow into the air exhaust tube.

Description

technical field [0001] The invention relates to an exhaust device of an underwater vehicle, in particular to an underwater power booster exhaust device with the function of waterproofing and backwashing. Background technique [0002] The ocean area accounts for about 70% of the earth's surface area, and its water volume accounts for about 97% of the total water volume on the earth. It is rich in resources and has important strategic value. Faced with the three major problems of the world's rapidly expanding population, the depletion of land resources, and the deteriorating environment, human beings pin their hopes for future development on the underdeveloped ocean. All countries in the world regard the development of the ocean, the development of marine economy and marine industry as an important strategic measure for national development, and call the 21st century the new century of marine resource development. The marine engineering equipment industry is the material and ...

AI Technical Summary

Problems solved by technology

The problem is that the exhaust of the one-way exhaust valve is driven by the exhaust gas of the exhaust pipe, and the waterproof backflow function is not strong. Therefore, there is an urgent need for an exhaust that can simultaneously solve the problem of underwater exhaust back pressure and realize the function of seawater backflow. Way
