Underwater secondary high-pressure bubble source based on push rod piston

Abstract

The invention provides an underwater secondary high-pressure bubble source based on a push rod piston and relates to the field of an underwater bubble source. The underwater secondary high-pressure bubble source based on the push rod piston mainly comprises a unidirectional sealing device, an air cylinder outer wall and the push rod piston. The bubble source realizes reliable sealing during secondary pressurizing by utilizing the designed unidirectional sealing device; and the unidirectional sealing device is connected with a gas source and a pressure storage cavity. Secondary pressurizing isformed through a speed-reducing motor and a spiral push rod, the piston is pushed through a driving motor and air in the pressure storage cavity is compressed. The whole bubble source adopts motive seal at the position of the piston and consists of two annular sealing rings; and an electromagnetic valve controls the bubble source to trigger and repeat.

Description

technical field [0001] The invention relates to an underwater secondary high-pressure air bubble source based on a push rod piston, belonging to the field of underwater air bubble sources. Background technique [0002] The high-pressure bubble source is a green and environment-friendly underwater bubble source, which can be used in ocean exploration, ice breaking and replacing traditional explosion sources. Therefore, it is of great practical significance to study a high-pressure bubble generator that can be used underwater. At present, the existing bubble sources all produce high-pressure annular bubbles or single-sided bubbles through the cooperation of the structure and the trigger device. There are great technical defects in the technology. The pipeline needs to withstand ultra-high pressure, and it is difficult to ensure that each position is well sealed. Moreover, the high-pressure seal has high cost and poor reliability, and at the same time, the complex structure wil...

Problems solved by technology

At present, the existing bubble sources all produce high-pressure annular bubbles or single-sided bubbles through the cooperation of the structure and the trigger device. There are great technical defects in the technology. The pipeline needs to withstand ultra-high pressure, and it is difficult to ensure that each position is well sealed. Moreover, high-pressure seals are costly and have poor reliability. At the same time, the complex structure will produce many unpredictable factors that will cause damage to the bubble generating device or interfere with the use environment.
