Description

Technical Field

[0001] The utility model relates to the technical field of underwater acoustic acquisition, and particularly relates to an underwater acoustic acquisition device. Background Technique

[0002] An underwater acoustic acquisition device usually consists of a hydrophone, a signal conditioning circuit, and a data storage and transmission module. The hydrophone is responsible for converting the underwater sound pressure signal into an electrical signal. The signal conditioning circuit processes the electrical signal, such as amplification and filtering, to improve the quality and usability of the signal. The data storage and transmission module stores the processed signal or transmits it in real time to other devices for further analysis.

[0003] In the prior art, some underwater acoustic acquisition devices can be used for underwater target detection. For example, by collecting the underwater acoustic signals reflected by underwater targets, the positioning, tracking, and identification of underwater targets can be achieved; by collecting underwater communication signals, the transmission and exchange of underwater information can be realized. However, in the specific use process, when collecting underwater acoustic signals, the unfixed underwater acoustic sensor is easily affected by factors such as water flow, water waves, and the movement of the device itself, resulting in shaking. This causes the intensity and frequency of the received underwater acoustic signals to change continuously, making the signals unstable and difficult to accurately analyze and process. Therefore, in view of the above problems, an underwater acoustic acquisition device is proposed. Content of the Utility Model

[0032] Refer to Figures 1 to 3, An underwater acoustic acquisition device, including a waterproof housing 1.

The first fixing block 3 is in the shape of a cube and is made of hard engineering plastic, with high strength and stability. Both the front and rear sides of the outside of the first fixing block 3 are fixedly connected with connecting plates 4. The connecting plates 4 are also made of strong metal materials and have been specially treated on the surface, with good corrosion resistance. The outside of the connecting plate 4 is fixedly connected with a fixing frame 5. The fixing frame 5 is in a U shape and is made of high-strength steel, with strong rigidity, which can provide stable support for the internal connecting shaft 6;

[0033] The inside of the fixing frame 5 is rotatably connected with a connecting shaft 6. The outside of the connecting shaft 6 is rotatably connected with a first rotating plate 7. The first rotating plate 7 is made of lightweight aluminum alloy, with good strength and light weight, which is convenient for flexible rotation on the connecting shaft 6. The inside of the fixing frame 5 is fixedly connected with an elastic force component for providing a reaction force. The elastic force component includes a telescopic rod 8. The telescopic rod 8 is made of stainless steel material, with good elasticity and wear resistance, which can provide a stable reaction force during the stretching and compressing processes. A spring 9 is sleeved on the outside of the telescopic rod 8. The spring 9 is made of high-elasticity steel and can produce elastic deformation when subjected to an external force, providing a return force for the first rotating plate 7. The outside of the telescopic rod 8 is fixedly connected to the inside of the fixing frame 5. The outside of the first rotating plate 7 is fixedly connected with a clamping rod 10. The clamping rod 10 is made of stainless steel material, with high strength and corrosion resistance, which can be firmly fixed on the first rotating plate 7. The inside of the first fixing block 3 is fixedly connected with an underwater acoustic sensor 13. The underwater acoustic sensor 13 is cylindrical and is composed of precision electronic components, which can sensitively receive sound signals in water and convert them into electrical signals for transmission to subsequent processing devices;

[0034] Refer to Figures 3 to 5, on the left side of the outside of the connecting plate 2, a plurality of support rods 11 are fixedly connected. The support rods 11 are cylindrical and made of high-strength steel, with good support performance, and can provide stable support for subsequent components. On the adjacent side of the two support rods 11, a baffle 12 is fixedly connected. The baffle 12 is rectangular and made of corrosion-resistant plastic material, and can effectively block the collision of external objects against the underwater acoustic sensor 13. On the outside of the baffle 12, a first fixing plate 14 is fixedly connected. The first fixing plate 14 is a rectangular metal plate, with a hard material, high strength and stability, and can provide a firm installation foundation for components such as the arc-shaped frame 15. On the outside of the first fixing plate 14, an arc-shaped frame 15 is fixedly connected. The arc-shaped frame 15 is made of aluminum alloy material with good flexibility and has a beautiful arc shape, and can provide a certain protective effect for the internal components. Inside the first fixing plate 14, a fixed shaft 16 is fixedly connected. On the outside of the fixed shaft 16, a plurality of second rotating plates 17 are rotatably connected. The fixed shaft 16 is made of high-quality alloy steel, with a smooth surface, and can provide stable rotational support for the second rotating plates 17;

[0035] On the outside of the first fixing plate 14, a plurality of fixing rods 18 are fixedly connected. The fixing rods 18 are cylindrical and made of high-strength steel, and can provide stable connection and support for other components. On the right side of the outside of the waterproof housing 1, a second fixing plate 19 is fixedly connected. The second fixing plate 19 is made of strong metal material and has good connection stability. On the outside of the second fixing plate 19, a second fixing block 20 is fixedly connected. On the outside of the second fixing block 20, a lifting ring 21 is fixedly connected. The lifting ring 21 is made of stainless steel material, with good strength and corrosion resistance, and is convenient for users to carry and operate the underwater acoustic acquisition device. The outside of the clamping rod 10 is engaged with the outside of the underwater acoustic sensor 13. The clamping rod 10 is slender and cylindrical, made of stainless steel material, with high strength and corrosion resistance, and can be firmly engaged on the underwater acoustic sensor 13 to ensure the installation stability of the underwater acoustic sensor 13. The outside of the underwater acoustic sensor 13 is in contact with the outside of the baffle 12. When the device is subjected to external force, the underwater acoustic sensor 13 can remain stable under the support of the baffle 12. One end of the spring 9 is fixedly connected to the outside of the first rotating plate 7, and the other end of the spring 9 is fixedly connected to the inside of the fixing bracket 5.

[0036] Working principle: First, the device is placed in water, and the hydroacoustic sensor 13 begins to receive sound wave signals in the water. Since the sensor 13 is fixed inside the waterproof housing 1, the external baffle 12 can effectively prevent external objects from colliding with the sensor, thereby ensuring the stability of signal reception. When the hydroacoustic sensor 13 receives the sound wave signal, the signal is converted into an electrical signal and transmitted to subsequent processing equipment through the connected circuit. At the same time, the rotating plate 7 can rotate flexibly under the action of the connecting shaft 6, and cooperates with the telescopic rod 8 and spring 9 of the elastic component to provide the rotating plate 7 with the necessary reaction force, ensuring that it can quickly rebound to the initial position when subjected to force, so that the clamping rod 10 can fix the hydroacoustic sensor 13, and then it will not fall off during use;

[0037] By putting the device into water, the force of falling causes the rotating plate 2 17 to open, and then the interior of the baffle 12 can be filled with water. When the collection is completed, the lifting ring 21 is pulled, and the pulling force causes the rotating plate 2 17 to close, and then the water quality can be extracted while collecting the water sound.

[0038] During operation, the fixing block 3 and the fixing frame 5 provide stable support for the connecting shaft 6, ensuring the flexibility and stability of the rotating plate 7. The design of the overall device enables it to effectively capture the underwater acoustic signal in an underwater environment and reliably transmit it to the processing system, thereby achieving efficient underwater acoustic collection. The design of the lifting ring 21 makes it easy for users to carry and operate the device when needed, improving the convenience and practicality of the device.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
