[0002] Underwater sonar imaging technology is an important means and tool for humankind to understand, develop, utilize, and protect the ocean. This technology has been widely applied in fields such as underwater target reconnaissance, seabed resource exploration, and underwater environmental monitoring. Underwater sonar imaging is mainly achieved through the reception and transmission of underwater sound waves. However, existing sound wave transceivers, when used at depths exceeding 3000 meters, will deform under water pressure, leading to equipment malfunction, and in severe cases, deformation of the casing and damage to internal components. Summary of the Invention

[0003] The purpose of this invention is to provide a method for protecting deep-sea acoustic signal transceivers through hydraulic pressure compensation, thereby solving the problems of deformation and damage to internal components in existing acoustic signal transceivers under high-pressure deep-sea environments.

[0004] The technical solution of the present invention is: a method for oil pressure compensation in a deep-sea acoustic signal transceiver, the method comprising:

[0005] S1. Assemble the deep-sea acoustic signal transceiver on the descent mechanism. The hydraulic compensator injects a preset amount of silicone oil into the sealed housing through the oil injection valve. After the injection is completed, start the descent mechanism to make the deep-sea acoustic signal transceiver sink in the water.

[0006] S2. In water, the hydraulic compensator calculates the volume of silicone oil inside the sealed housing based on an integrated adaptive hydraulic compensation algorithm based on PID control, and drives the oil injection valve to inject and discharge silicone oil into the sealed housing to maintain the pressure balance inside and outside the deep-sea acoustic signal transceiver.

[0007] Step S2 includes:

[0009] S22. Calculate the compensation increment u(t) using a PID controller:

[0010] u(t) = K p*e(t)+K i *∫e(τ)dτ+K d *de(t) / dt;

[0011] Where K p K is the proportionality coefficient. i K is the integral coefficient; d The differential coefficient is β; the relationship between this increment u(t) and the change in silicone oil volume ΔV is: ΔV=u(t)*β, where β is the silicone oil compressibility coefficient;

[0012] S23. Based on ΔV, control the volume of silicone oil injected into the sealed housing by the oil injection valve to maintain the pressure P inside the chamber. int Approaching P ext +k offset .

[0013] In any of the above technical solutions, further, while compensating for oil pressure in the water, the deep-sea acoustic signal transceiver uses the transmitting module to control the transmitting transducer to transmit acoustic pulses to the outside world. The receiving processor listens for the echo through the receiving transducer and converts it into an electrical signal. The electrical signal is transmitted to the receiving module for preliminary processing and amplification. The processed data is transmitted to the processing module in the transmitting processing chamber via the receiving watertight connector, the watertight cable connector assembly, and the transmitting watertight connector. The processing module analyzes the data and uses the acoustic positioning principle to detect, identify, and locate underwater targets.

[0014] In any of the above technical solutions, the process of receiving the transducer's echo and converting it into an electrical signal further includes:

[0015] When an external sound wave signal encounters an obstacle and is reflected, it generates an echo that propagates to a receiving transducer. The receiving transducer transmits the vibration generated by the echo to its internal elements, which then convert it into an electrical signal using the piezoelectric effect.

[0016] In any of the above technical solutions, if the pressure error e(t) calculated in step S21 is greater than a preset threshold, an alarm is triggered and the rate of silicone oil throughput is increased in step S23.

[0017] A corresponding apparatus is also provided that uses the oil pressure compensation method for a deep-sea acoustic signal transceiver device according to any of the above technical solutions. The apparatus includes: a receiver processor, a transmitter processing compartment, and a watertight cable connector assembly.

[0019] The receiving and processing unit includes a sealed housing and a hydraulic compensator. The hydraulic compensator is connected to the inside of the sealed housing through an oil injection valve connected between the hydraulic compensator and the sealed housing. A bidirectional oil injection pump is provided inside the hydraulic compensator next to the interface of the oil injection valve. The hydraulic compensator adjusts the pressure balance inside and outside the sealed housing by feeding and discharging silicone oil.

[0020] In any of the above technical solutions, the receiving processor further includes a receiving transducer and a receiving module;

[0021] The sealed housing is a rectangular shell without covers on the left and right sides. The inside of the sealed housing is equipped with a receiving module. The two uncovered sides of the sealed housing are respectively equipped with a receiving transducer and a transparent panel. The receiving transducer, the transparent panel and the sealed housing form a sealed rectangular shell. A cylindrical hydraulic compensator is installed on the top of the other side of the sealed housing.

[0023] The bladder layer covers the outer surface of the receiving transducer and wraps the edges. The bladder layer does not cover the inner side of the receiving transducer connecting the sealing housing. A ring of protrusions is provided at a specific position on the bladder layer. The protrusions fit into the grooves on the matching sealing housing to achieve the sealing between the receiving transducer and the sealing housing.

[0024] The array plate is set inside the skin layer, and the inner wall of the skin layer has a concave-convex structure that matches the array plate, which interlocks to prevent the array plate from being misaligned within the skin layer.

[0025] Several arrays are installed on array carriers, which are located on one side of the array board. The array carriers are electrically connected to the receiving module via ribbon cables.

The watertight launch connector, launch transducer, launch module and processing module are electrically connected to each other via ribbon cables.

[0028] In any of the above technical solutions, furthermore, clamp grooves are provided on the inner sides of both bottom surfaces of the cabin, and the cylindrical outer shell of the cabin is installed and sealed by clamp tensioning through the clamp grooves.

[0029] The beneficial effects of this invention are:

[0030] The technical solution in this invention can be applied at depths exceeding 6000m, protecting internal components from damage. By adjusting the pressure balance inside and outside the chamber through a hydraulic compensator, silicone oil is injected into the chamber when it is at the surface. After submersion, the volume of silicone oil changes with the water pressure, thus compensating for the underwater pressure. This improves upon the difficulty of using sonar transceivers in deep-sea environments and solves some problems with existing devices. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0039] In the following description, many specific details are set forth in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0040] like Figure 1 As shown, this embodiment provides an oil pressure compensation method for a deep-sea acoustic signal transceiver, the method comprising:

[0041] S1. Assemble the deep-sea acoustic signal transceiver on the descent mechanism. The hydraulic compensator injects a preset amount of silicone oil into the sealed housing through the oil injection valve. After the injection is completed, start the descent mechanism to make the deep-sea acoustic signal transceiver sink in the water.

[0042] S2. In water, the hydraulic compensator calculates the volume of silicone oil inside the sealed housing based on an integrated adaptive hydraulic compensation algorithm based on PID control, and drives the oil injection valve to inject and discharge silicone oil into the sealed housing to maintain the pressure balance inside and outside the deep-sea acoustic signal transceiver.

[0043] Step S2 includes:

[0044] S21. The external water pressure P is collected in real time by a pressure sensor at time intervals of Δt. ext and cabin pressure P int Calculate the current pressure error e(t) = P ext -P int +k offset , where k offset This is the preset safety offset.

[0045] S22. Calculate the compensation increment u(t) using a PID controller:

[0046] u(t) = K p *e(t)+K i *∫e(τ)dτ+K d *de(t) / dt;

[0047] Where K p K is the proportionality coefficient. i K is the integral coefficient; d The differential coefficient is β. The relationship between the increment u(t) and the volume change ΔV of the silicone oil is: ΔV=u(t)*β, where β is the compressibility coefficient of the silicone oil.

[0048] S23. Based on ΔV, control the volume of silicone oil injected into the sealed housing by the oil injection valve to maintain the pressure P inside the chamber. int Approaching P ext +k offset .

[0049] In addition, if the pressure error e(t) calculated in step S21 is greater than a preset threshold, an alarm is triggered and the rate of silicone oil throughput is increased in step S23.

[0050] like Figure 2 As shown, the corresponding device using the above-described hydraulic compensation method for a deep-sea acoustic signal transceiver includes: a receiver processor 1, a transmitter processing compartment 2, and a watertight cable connector assembly 3.

[0051] The receiver processor 1 is equipped with a receiver watertight connector 121, and the transmitter processing compartment 2 is equipped with a transmitter watertight connector 22. The watertight cable connector assembly 3 connects the receiver processor 1 and the transmitter processing compartment 2 through the receiver watertight connector 121 and the transmitter watertight connector 22.

[0052] The transmitting and processing chamber 2 emits sound wave pulses to the outside world. When the sound wave pulses encounter a target in the water, they generate an echo signal. The receiving and processing unit 1 listens to the echo signal and transmits it to the transmitting and processing chamber 2. The transmitting and processing chamber 2 analyzes the echo signal and uses the principle of sound wave positioning to detect, identify and locate the target in the water. The watertight cable connector 3 completes the transmission of the sound wave signal between the receiving and processing unit 1 and the transmitting and processing chamber 2.

[0053] like Figure 3 and Figure 4 As shown, the receiver processor 1 includes a receiver transducer 11, a sealed housing 12, a receiver module 13, and a hydraulic compensator 14. The sealed housing 12 is a rectangular shell without covers on the left and right sides. The receiver module 13 is installed inside the sealed housing 12. The receiver transducer 11 and the transparent panel are respectively installed on the two uncovered sides of the sealed housing 12. The receiver transducer 11, the transparent panel, and the sealed housing 12 form a sealed rectangular shell. A cylindrical hydraulic compensator 14 is installed on the top of the other side of the sealed housing 12. The hydraulic compensator 14 is connected to the inside of the sealed housing 12 through an oil injection valve 122 connected between the hydraulic compensator 14 and the sealed housing 12. A bidirectional oil injection pump is provided inside the hydraulic compensator 14 next to the interface of the oil injection valve 122.

[0054] The sealing housing 12 is pressure-resistant by being filled with oil, and the pressure balance inside and outside the sealing housing 12 is adjusted by the oil pressure compensator 14. When in water, silicone oil is injected into the sealing housing 12 through the oil injection valve. After entering the water, the volume of silicone oil in the sealing housing 12 changes with the water pressure, and the oil pressure compensates for the water pressure underwater.

[0055] The receiving transducer 11 includes a sheath layer 111, an array plate 112, an array element 113, and an array element carrier 114.

[0056] The bladder layer 111 covers the outer surface of the receiving transducer 11 and wraps around its edges. The bladder layer 111 does not cover the inner side of the receiving transducer 11 and the sealing housing 12. A ring of protrusions is provided at a specific position on the bladder layer 111. The protrusions fit into the grooves on the matching sealing housing 12 to achieve the sealing of the receiving transducer 11 and the sealing housing 12.

[0057] Since the inner surface of the receiving transducer 11 is not wrapped by the sheath layer 111, after the hydraulic compensator 14 injects oil into the inside of the sealing housing 12, the inside of the receiving transducer 11 is also filled with oil.

[0058] The array plate 112 is disposed inside the skin layer 111. The inner wall of the skin layer 111 is provided with concave and convex structures that match the array plate 112, which fit together to prevent the array plate 112 from being misaligned within the skin layer 111.

[0059] A number of array elements 113 are mounted on an array element carrier 114, which is located on one side of an array plate 112. The array element carrier 114 is electrically connected to the receiving module 13 via a ribbon cable.

[0060] External acoustic signals act on the bladder layer 111 through the water medium, causing vibration; the vibration is transmitted to the inductor 113, which converts it into an electrical signal using the piezoelectric effect; these signals are sent to the receiving module 13 through the inductor carrier 114 and the ribbon cable for amplification, filtering and digital processing.

[0061] like Figure 5 As shown ( Figure 5 The cylindrical outer shell of the cabin is omitted, but the two bottom surfaces of the cabin are retained. The launch processing cabin 2 includes a cabin body 21, a launch watertight connector 22, a launch transducer 23, a launch module 24, and a processing module 25. The cabin body 21 is a cylindrical outer shell, and the launch module 24 and the processing module 25 are installed inside. The launch transducer 23 is installed on the outside of the side of the cabin body 21. The launch watertight connector 22 is located at the bottom of the cabin body 21. The launch watertight connector 22, the launch transducer 23, the launch module 24, and the processing module 25 are electrically connected to each other through ribbon cables.

[0062] The inner sides of the two bottom surfaces 211 of the cabin 21 are provided with clamp grooves 2111. The cylindrical outer shell of the cabin is installed and sealed by clamping the clamp grooves 2111.

[0063] The transmitting transducer 23 is made by potting and is not filled with oil; the structural components of the cabin 21 are made of titanium alloy TC4, which meets the requirements for corrosion resistance.

[0064] In the water, the transmitting module controls the transmitting transducer to emit sound wave pulses to the outside world. When the sound wave pulses encounter a target in the water, they are reflected, generating an echo signal. The receiving processor listens to the echo through the receiving transducer and converts it into an electrical signal. The electrical signal is transmitted to the receiving module for preliminary processing and amplification. The processed data is transmitted to the processing module in the transmitting processing compartment via the receiving watertight connector, the watertight cable connector assembly, and the transmitting watertight connector. The processing module analyzes the data and uses the principle of acoustic positioning to detect, identify, and locate targets in the water.

[0065] When an external sound wave signal encounters an obstacle and is reflected, it generates an echo that propagates to a receiving transducer. The receiving transducer transmits the vibration generated by the echo to its internal elements, which then convert it into an electrical signal using the piezoelectric effect.

[0072] u(t) = K p *e(t)+K i *∫e(τ)dτ+K d *de(t) / dt;

[0073] Where K p K is the proportionality coefficient. i K is the integral coefficient; dThe differential coefficient is β. The relationship between the increment u(t) and the volume change ΔV of the silicone oil is: ΔV=u(t)*β, where β is the compressibility coefficient of the silicone oil.
