Description

Technical Field

[0001] The present invention belongs to the field of underwater instrument and equipment, and particularly relates to a system for balancing the air pressure in the air chamber of an underwater sound generator. Background Art

[0002] Existing sound generators vibrate to produce sound by pushing a template back and forth. The imbalance between the external water pressure and the internal air pressure of the template makes it difficult to push the template, resulting in unsatisfactory sound production efficiency or even inability to work properly. At present, there is a device that connects a balance airbag to the sound generator to make the air pressure in the air chamber of the sound generator adapt to the pressure corresponding to different water depths. However, due to the limitations of the airbag volume in the structural layout and the safety problems caused by excessive initial inflation pressure, this device cannot enable the sound generator to work normally in a large-depth environment. To improve the working ability of the sound generator, it is necessary to invent a method for balancing the air pressure in the air chamber of the sound generator that can adapt to water depths of up to 100 meters. Summary of the Invention

[0003] To solve the problem that the existing sound generator cannot work normally at a water depth of up to 100 meters, the present invention provides a system for balancing the air pressure in the air chamber of an underwater sound generator, which can extend the normal working depth of the existing sound generator from the ten-meter level to the hundred-meter level, and has the effects of a wide depth adjustment range, sensitive control of the air pressure value in the underwater working state, and strong adaptability to external water pressure fluctuations.

[0004] A system for balancing the air pressure in the air chamber of an underwater sound generator includes a deck control device, a composite function tow cable, and an underwater device. Among them, the deck control device includes a console and a gas cylinder with an electrically controlled air valve. The composite function tow cable contains an air pipe and a cable connecting the deck control device and the underwater device. The underwater device includes a depth sensor, a pressure sensor installed on the underwater generator, and a balance airbag with an airbag air valve.

[0005] The console is electrically connected to the electrically controlled air valve of the gas cylinder and is connected to the tow cable connector of the underwater sound generator through the cable part in the composite function tow cable, and then connected to the controller of the airbag air valve inside the underwater generator and the data receiving devices of the depth sensor and the pressure sensor. The air path of the electrically controlled air valve of the gas cylinder is connected to the airbag air valve, the pressure sensor, the air chamber of the underwater sound generator, and the balance airbag inside the underwater sound generator through the air pipe part in the composite function tow cable to form a complete air path.

[0006] After the underwater sound generator dives underwater, the console controls the electrically controlled air valve to connect it to the air pipe in the composite function tow cable, and then continuously receives the signals of the depth sensor and the pressure sensor. The console makes a decision based on the values of these two signals to determine whether to control the airbag air valve inside the underwater sound generator to open and inflate.

[0007] Further, during the underwater diving process of the underwater sound generator, the console controls the electric control valve of the gas cylinder to open and connect it to the air pipe in the composite function tow cable. At the same time, it continuously receives the water pressure measurement value and air pressure measurement value sent by the depth sensor and air pressure sensor via the cable in the composite function tow cable, and judges whether the air pressure measurement value is 0.05 MPa higher than the water pressure measurement value. If so, the airbag valve is closed; if not, the airbag valve is opened. Until the depth of the underwater sound generator is 10 m higher than the target water depth, the console closes the airbag valve, and the balance airbag continues to dive to the target water depth under the current air pressure. Finally, the underwater sound generator enters the stable operation stage.

[0008] Further, when the underwater sound generator is in the stable operation stage, the airbag valve is in the closed state at this time, and the balance airbag is in a state of being compressible and expandable, and can deform with the fluctuation of the external water pressure, so as to adaptively adjust the air pressure balance of the air chamber of the underwater sound generator.

[0009] Further, after the task is completed, the underwater sound generator enters the floating recovery stage. At this time, the console controls the electric control valve of the gas cylinder to close, and opens the interface between the air pipe in the composite function tow cable and the outside atmosphere. At the same time, the console continuously receives the water pressure measurement value and air pressure measurement value sent by the depth sensor and air pressure sensor via the cable in the composite function tow cable, and judges whether the air pressure measurement value is 0.05 MPa higher than the water pressure measurement value. If so, the airbag valve is opened to deflate the balance airbag; if not, the airbag valve is closed until the pressure in the underwater sound generator is completely emptied after surfacing.

[0010] Further, the depth sensor and the air pressure sensor first receive and process the signals through the original instrument cabin of the underwater sound generator, and then send the processed water pressure measurement value and air pressure measurement value to the console through the cable in the composite function tow cable.

[0011] Beneficial effects:

[0012] 1. The present invention provides a system for balancing the air pressure in the air chamber of an underwater sound generator, which includes a deck control device, a composite function tow cable, and an underwater device. Among them, the deck control device includes a console and a gas cylinder, the composite function tow cable contains an air pipe and a cable, and the underwater device includes a depth sensor, an air pressure sensor, and a balance airbag; after the underwater sound generator dives underwater, the electric control valve is controlled by the console to connect it to the air pipe in the composite function tow cable, and then the signals of the depth sensor and the air pressure sensor are continuously received. The console makes a decision based on the numerical values of these two signals to judge whether to control the airbag valve in the underwater sound generator to open and inflate; compared with the existing technology, the air chamber air pressure balance system proposed by the present invention can expand the normal working depth of the existing sound generator from the ten-meter level to the hundred-meter level, and has the effects of a wide depth adjustment range, sensitive control of the air pressure value in the underwater working state, and strong adaptability to external water pressure fluctuations.

After the underwater sound generator dives underwater, the air valve of the high-pressure gas cylinder is controlled by a console to connect it to the air pipe in the towing cable, and then the signals of the depth sensor and the air pressure sensor are continuously received. The console makes a decision based on the values of these two signals, judges and controls the opening of the high-pressure air valve in the sound generator to inflate, which can improve the working ability of the underwater sound generator in a deep-depth environment, solve the functional deficiency that the original sound generator can only emit sound normally at a water depth of about ten meters, and expand its working range to a water depth of about one hundred meters.

During the stable operation stage of the underwater sound generator, the balance airbag is in a state of being compressible and expandable, and can deform with the fluctuation of the external water pressure, so as to adaptively adjust the air pressure balance in the sound generator air chamber and ensure the stable operation and sound emission of the underwater sound generator.

[0015] 4. The present invention provides a system for balancing the air pressure in the air chamber of an underwater sound generator. During the floating and recovery stage of the underwater sound generator, as the underwater generator floats, it is necessary to release gas appropriately at the same time to prevent damage caused by excessive pressure difference inside and outside the underwater sound generator.

[0019] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0020] As Figure 1As shown in the figure, a system for balancing the air pressure in the air chamber of an underwater sound generator includes a deck control device, a composite function tow cable, and an underwater device. Among them, the deck control device includes a console and a gas cylinder with an electronically controlled air valve. The composite function tow cable contains an air pipe and a cable connecting the deck control device and the underwater device. The underwater device includes a depth sensor, a pressure sensor, a balance airbag with an airbag air valve, a tow cable joint, an air pipe, a sound generator air chamber, etc. installed on the underwater generator. When in use, first arrange the deck control device. The console cable connects the electronically controlled air valve of the high-pressure gas cylinder and the cable joint in the composite function tow cable. The gas path of the high-pressure gas cylinder is connected to the air pipe joint in the composite function tow cable. The outside of the underwater sound generator is connected to the cable part in the composite function tow cable through the tow cable joint, and the depth sensor and the balance airbag are installed. Inside, it is connected to the sound generator air chamber, the high-pressure airbag air valve, the pressure sensor, and the balance airbag through the air pipe. Among them, the depth sensor and the pressure sensor first receive and process the signals through the original instrument cabin of the underwater sound generator, and then send the processed water pressure measurement value and air pressure measurement value to the console through the cable in the composite function tow cable.

[0021] Specifically, as Figure 2 shown in the figure, the console cable connects the electronically controlled air valve of the gas cylinder and connects to the tow cable joint of the underwater sound generator through the cable part in the composite function tow cable, and then connects to the control device of the airbag air valve inside the underwater generator and the data receiving devices of the depth sensor and the pressure sensor. The gas path of the electronically controlled air valve of the gas cylinder is connected to the airbag air valve, the pressure sensor, the sound generator air chamber, and the balance airbag inside the underwater sound generator through the air pipe part in the composite function tow cable to form a complete gas path. After confirmation, the next step can be entered, and the sound generator enters the water.

[0022] After the underwater sound generator enters the water and dives, the electronically controlled air valve is controlled by the console to connect to the air pipe in the composite function tow cable, and then continuously receives the signals of the depth sensor and the pressure sensor. The console makes a decision based on the values of these two signals to determine whether to control the airbag air valve inside the underwater sound generator to open and inflate.

[0023] Specifically, as Figure 3 shown in the figure, during the process of the underwater sound generator entering the water and diving, the console controls the electronically controlled air valve of the gas cylinder to open and connect to the air pipe in the composite function tow cable. At the same time, it continuously receives the water pressure measurement value and the air pressure measurement value sent by the depth sensor and the pressure sensor through the cable in the composite function tow cable, and judges whether the air pressure measurement value is 0.05 MPa higher than the water pressure measurement value. If it is, the airbag air valve is closed. If it is not, the airbag air valve is opened to ensure that the balance airbag maintains the maximum expansion state until the depth of the underwater sound generator is 10 m higher than the target water depth. Then the console closes the airbag air valve, and the balance airbag continues to dive to the target water depth under the current air pressure. Finally, the underwater sound generator enters the stable operation stage.

[0024] When the underwater sound generator is in the stable operation stage, the airbag air valve is in the closed state at this time, and the balance airbag is in a state of being compressible and expandable, and can deform with the fluctuation of the external water pressure, so as to adaptively adjust the air pressure balance in the air chamber of the underwater sound generator and ensure its stable operation and sound generation.

[0025] After the task is completed, the underwater sound generator enters the floating recovery stage. As the underwater generator floats, it is necessary to release gas appropriately at the same time to prevent the pressure difference between the inside and outside of the underwater sound generator from being too large; at this time, the console controls the electric control air valve of the gas cylinder to close, and opens the interface between the air pipe in the composite function tow cable and the outside atmosphere. At the same time, the console continuously receives the water pressure measurement value and air pressure measurement value sent by the depth sensor and air pressure sensor via the cable in the composite function tow cable, and judges whether the air pressure measurement value is 0.05 MPa higher than the water pressure measurement value. If so, the airbag air valve is opened to release gas from the balance airbag. If not, the airbag air valve is closed until the pressure inside the underwater sound generator is completely emptied after surfacing.

[0026] Thus, the present invention realizes the air pressure balance in the air chamber of the underwater sound generator during the working state and can work and generate sound normally at a depth of hundreds of meters underwater.

[0027] Of course, the present invention may also have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can certainly make various corresponding changes and deformations according to the present invention, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present invention.
