Description

Technical Field

[0001] This utility model relates to the field of underwater acoustic signal detection technology, specifically a cylindrical hydrophone with a shunt structure. Background Technology

[0002] With the continuous development of underwater target stealth technology, vector hydrophones have become the main receivers in low-frequency and even very low-frequency underwater target detection technology, and are widely used in the field of underwater acoustic engineering. As a new type of underwater acoustic transducer, the vector hydrophone can provide underwater sound field particle velocity information and has excellent low-frequency cosine directivity, enabling it to achieve high gain with small apertures.

[0003] According to the description in the patent website of a vector hydrophone (authorization announcement number: CN 113155263 A), "This invention discloses a vector hydrophone, belonging to the field of underwater acoustic signal detection technology. The hydrophone includes a composite acoustic sensor and a sound-transparent sealed cavity for suspending the composite acoustic sensor. The sound-transparent sealed cavity is filled with a sound-transparent liquid medium; the density of the sound-transparent liquid medium is between 0.9 g / cm3 and 1.2 g / cm3. This invention can improve the stability and environmental adaptability of the vector hydrophone, which is beneficial to the accuracy of underwater signal detection."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this utility model achieves rigid fixation to the external platform via screws. The cable outlet leads the cable from the composite acoustic sensor to the outside of the hydrophone. After oil filling, the oil filling hole and vent hole are sealed with watertight screws to prevent liquid leakage. In actual use, because the connecting cable of this device is exposed to the outside, problems such as pulling and slipping between the connecting wires and sealing issues can easily occur. At the same time, because this device needs to be submerged underwater and the outer shell model is fixed, the water entry resistance can easily increase. Therefore, it is necessary to improve the device by creating a cylindrical hydrophone with a flow splitting structure to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a cylindrical hydrophone with a flow splitting structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical hydrophone with a diversion structure, comprising a mounting plate, a connecting rope fixedly connected to the top of the mounting plate, a mounting cylinder provided at the bottom of the mounting plate, a locking bolt provided between the mounting plate and the mounting cylinder, a buffer pad fixedly connected inside the mounting cylinder, a protective limiting mechanism provided at the bottom of the mounting plate, and an auxiliary diversion mechanism provided outside the mounting cylinder;

[0037] Example 2:

[0038] Based on Embodiment 1, the fixed outer casing model in the prior art easily leads to increased water resistance. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problem. Please refer to Embodiment 2.

After installation, the external connection transmission harness and the connecting wire 515 are plugged in. After plugging in, the operator rotates the bidirectional threaded rod 525. The rotation of the bidirectional threaded rod 525, in conjunction with the limiting rod 526, causes the movable plate 522 to move, which, in conjunction with the connecting frame 523, causes the sealing gasket 524 to move, thereby satisfying the positioning and sealing between the connecting wire 515 and the external connection transmission harness. The operator then pulls the second sliding plate 64. The movement of the second sliding plate 64, in conjunction with the second spring 65, causes the locking block 6 to... The movement of the 6th movement achieves the limiting between the locking block 66 and the fixing block 62. After inserting the flow guide 61 into the installation cylinder 3, the second slide plate 64 is released, completing the installation and disassembly process of the flow guide 61. After installation, the external deployment and retraction device is connected to the connecting rope 2. After connection, the device is dropped into the water. When the device touches the water surface, it vibrates, causing the composite acoustic sensor 514 to move. Through the movement of the composite acoustic sensor 514, in conjunction with the connecting plate 513, the slider 512 slides inside the connecting box 511. In conjunction with the connecting rod 5110, the first slide plate 519 slides outside the slide rod 516. In conjunction with the first spring 517, the damping rod 518 and the buffer pad 4, the vibration reduction process of the composite acoustic sensor 514 is achieved.
