Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an underwater wave transmitter, and more particularly to an underwater wave transmitter that equalizes the pressure inside the wave transmitter with respect to the water depth pressure.

[Background of the idea]

Conventional underwater transmitters use solenoid valves, position detection sensors, and bellows to control the gas that equalizes the water depth pressure and the pressure inside the transmitter, so when the solenoid valves open and close, shocking pressure waves are generated and There were drawbacks such as the solenoid valve opening and closing noise.

Another drawback was that gas was released into the water during pressure adjustment.

[Purpose of the invention] The purpose of the invention is to make it possible to supply a pressure equal to water pressure without releasing gas into the water when adjusting the internal pressure of an underwater transmitter.

[Summary of the idea]

In order to achieve the above-mentioned object, the present invention uses a regulator, and also uses the regulator when the water pressure decreases in order to prevent gas from being released into the water.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3. The structure of this underwater transmitter consists of an underwater transmitter 1, a pressure regulator 2, a pressure reduction regulator 3, a high pressure tank 4, and an exhaust tank 5.

In operation of this underwater transmitter, when the outside water pressure increases, the valve of the pressurizing regulator 2 opens to reduce the pressure of the gas in the high-pressure tank 4 to a pressure equal to the water pressure, and supplies it to the underwater transmitter 1. When the pressure inside the underwater transmitter 1 becomes equal to the water pressure, the valve closes. When the outside water pressure decreases, the valve of the pressure reducing regulator 3 opens, and the gas is released into the exhaust tank 5 while maintaining a pressure difference so that the pressure of the gas in the underwater transmitter 1 becomes equal to the water pressure. When the pressure inside the underwater transmitter 1 becomes equal to the water pressure, the valve of the pressure reducing regulator 3 is closed.

FIG. 2 shows the structure of the pressure regulator 2.
This regulator is designed so that the casing 21 is closed by external water pressure.
A diving exhalation regulator in which a piston 22 moves against a main spring 23 has the same structure. This regulator, whose structure is shown in FIG. 3, is a newly devised regulator. The operation of the pressure reducing regulator will be explained below.

When the external water pressure applied to the casing 31 decreases,
A piston 32 within the casing presses down the main spring 23. This operation opens a gas passage leading from the primary side input P connected to the wave transmitter to the secondary side output S connected to the exhaust tank. When the pressure on the primary side and the external water pressure are equal, the piston is raised by the force of the main spring, and the passage is closed, and the passage for fluid pressure from the wave transmitter side to the exhaust tank is blocked.

[Effect of idea]

According to the present invention, the underwater transmitter can be constructed with less than half the number of parts and weigh less than half that of conventional underwater transmitters.
