Description

Technical Field

[0001] The present invention belongs to the technical field of vibration reduction and noise reduction, and in particular relates to a vibration reduction and noise reduction structure for a deepwater transducer array and an installation method thereof. Background Art

[0002] With the development of modern communication technology, humanity's exploration of the deep sea continues to deepen. Deepwater hydroacoustic technology, which promotes the advancement of deep-sea scientific research, has been vigorously developed. Deepwater vibration and noise reduction technology is a very important technical support. Both the military and civilian commercial fields have put forward higher requirements for deepwater vibration and noise reduction technology.

[0003] Transducer arrays are primarily used on underwater vehicles and other equipment, both stationary and in motion. With the continued expansion of underwater transducers into the deep sea, traditional transducer array vibration and noise reduction structures are no longer able to simultaneously meet the deep-water requirements and vibration and noise reduction requirements of underwater vehicles. Currently, existing transducer array vibration and noise reduction structures in China are insufficient for deepwater use. Most existing structures utilize rigid connections, lacking vibration and noise reduction capabilities. This significantly impacts the acoustic performance of the transducer array and reduces its effectiveness. Traditional vibration and noise reduction structures are either unable to withstand high pressures or lose their vibration and noise reduction capabilities under high pressures. Common transducer array vibration and noise reduction structures often utilize elastic connections with springs or damping materials. These two connection methods can significantly deform under high pressures, turning the elastic connection into a rigid connection and losing their vibration and noise reduction capabilities. Furthermore, these connection methods can suffer structural damage under high pressures, making them unable to withstand high pressures and, more importantly, unable to achieve vibration and noise reduction. Summary of the Invention

[0004] In response to the above problems, the purpose of the present invention is to provide a shock-absorbing and noise-reducing structure and installation method for a deep-water transducer array. It adopts a multi-layer petal-tooth buckle structure, which not only plays a role in shock absorption and noise reduction, but also has a certain pressure-resistant function. A pressure plate is provided in the shell, which is suitable for deep-water work, and has simple processing and low cost.

[0005] The technical solution of the present invention is: a shock-absorbing and noise-reducing structure for a deep-water transducer array, comprising a shell, a bracket and a transducer mounted on the bracket; the shell is hollow inside, and the inner surface is provided with a pressure plate mounting groove and a multi-petal tooth mounting groove in sequence, a pressure plate is provided in the pressure plate mounting groove, and the pressure plate is fixedly connected to the shell; the bracket is provided with a multi-petal tooth on the outside, and the multi-petal tooth cooperates with the multi-petal tooth mounting groove, a plurality of stepped hole sealing cavities are provided in the middle of the right end of the bracket, the transducer is fixedly mounted in the stepped hole sealing cavity, and the bracket and the outer side of the right end of the shell are provided with sound-transmitting rubber.

[0006] The space between the multi-petal buckle and the multi-petal buckle installation groove is filled with damping and shock-absorbing material.

[0007] The multi-petal buckle tooth installation groove is a four-petal buckle tooth installation groove, and the multi-petal buckle tooth is a four-petal buckle tooth.

[0008] The thickness of the multi-petal buckle is 5 mm, and the thickness of the damping and shock-absorbing rubber material is 5 mm.

DETAILED DESCRIPTION

[0027] Example 1

[0028] In order to overcome the problem that the existing transducer array spring or damping material elastic connection shock absorption and noise reduction structure will undergo large deformation under high pressure, causing the elastic connection to become a rigid connection and lose the shock absorption and noise reduction function, the present invention provides a Figure 1 The shock-absorbing and noise-reducing structure for a deepwater transducer array shown in the figure adopts a multi-layer petal-tooth buckle structure, which not only plays the role of shock-absorbing and noise-reducing, but also has a certain pressure-resistant function. A pressure plate is provided in the shell, which is suitable for deepwater work and has simple processing and low cost.

[0029] like Figure 1 As shown, a vibration reduction and noise reduction structure for a deep-water transducer array includes a housing 1, a bracket 3, and a transducer 6 mounted on the bracket 3; wherein:

[0030] The shell 1 is hollow inside, and the inner surface is provided with a pressure plate mounting groove 10 and a multi-petal buckle mounting groove 11 in sequence. A pressure plate 7 is provided in the pressure plate mounting groove 10, and the pressure plate 7 is fixedly connected to the shell 1;

[0031] The outside of the bracket 3 is provided with a multi-petal buckle 12, and the multi-petal buckle 12 cooperates with the multi-petal buckle mounting groove 11. The middle part of the right end of the bracket 3 is provided with a plurality of stepped hole sealing cavities 13, and the transducer 6 is fixedly installed in the stepped hole sealing cavity 13. The right end of the bracket 3 and the outer side of the right end of the shell 1 are provided with sound-transmitting rubber 4.

[0032] The present invention utilizes the multi-petal clasp 12, which mates with the multi-petal clasp mounting groove 11, to create a multi-layered clasp connection between the housing 1 and the bracket 3. When pressure increases, the bracket 3 slightly shifts rearward, while maintaining an elastic connection that does not compromise the vibration and noise reduction effects. When pressure increases again, the bracket 3 shifts rearward until it contacts the pressure plate 7, which now bears the pressure. This invention not only addresses the pressure-bearing issue but also achieves vibration and noise reduction.

[0033] Preferably, based on Example 1, in this embodiment, the space between the multi-petal clasp 12 and the multi-petal clasp mounting groove 11 is filled with a damping and shock-absorbing material 2. The multi-petal clasp mounting groove 11 is a four-petal clasp mounting groove, and the multi-petal clasp 12 is a four-petal clasp. The multi-petal clasp 12 has a thickness of 5 mm, and the damping and shock-absorbing rubber material 2 has a thickness of 5 mm. The pressure plate 7 is fixedly connected to the housing 1 using screws 9.

[0034] In actual use, the use of shock-absorbing and damping material 2 between the housing 1 and the bracket 3 effectively reduces vibration and noise, minimizing the impact of noise on the array transducer 6. The inner wall of the housing 1 utilizes a four-petal toothed buckle structure, connected to the bracket 3 via damping and damping rubber. The toothed buckle is 5mm thick, and the damping and damping rubber layer is 5mm thick. When subjected to pressure, the bracket 3 moves backward. The front end of the toothed buckle is subjected to tension from the damping and damping rubber, while the rear end is subjected to resistance from the damping and damping rubber. This not only reduces vibration and noise, but also provides a certain degree of pressure resistance.

[0035] Preferably, based on Example 1, in this embodiment, the right end of the bracket 3 is flush with the right end of the shell 1, and the left end of the bracket 3 is provided with a pressure block 14, and the pressure block 14 is parallel to the pressure plate 7; a shock-absorbing damping pad 8 is provided between the bracket 3 and the pressure block 14.

[0036] In actual use, when encountering greater pressure, the bracket 3 moves backward and contacts the shock-absorbing damping pad 8 on the pressure-bearing plate 7. At this time, the pressure-bearing plate 7 not only bears the pressure, but also plays the role of shock absorption and noise reduction.

[0037] Preferably, based on Example 1, in this embodiment, the distance between the pressure plate 7 and the pressure block 14 is preset to 1 mm.

[0038] In actual use, the shock-absorbing and damping pad 8 is assembled on the pressure plate 7 and fastened to the housing 1, leaving a 1mm gap between the shock-absorbing and damping pad 8 and the rear end surface of the bracket 3. The pressure plate 7 and the shock-absorbing and damping pad 8 only bear the pressure when subjected to greater pressure.

[0039] Preferably, based on Example 1, in this embodiment, a shock-absorbing pad 5 is provided in the stepped hole sealing cavity 13 .

[0040] In actual use, the shock-absorbing pad 5 can effectively reduce the vibration noise between the transducer 6 and the stepped hole sealing cavity 13 .

[0042] Based on Example 2, a method for installing a vibration-damping and noise-reducing structure for a deepwater transducer array is provided, and the specific steps are as follows:

[0043] S1: Clean and wash all structural parts of the vibration reduction and noise reduction structure for the deep-water transducer array, and sandblast the surfaces of the shell 1, bracket 3 and the damping and vibration reduction material 2;

[0044] S2: Clean and wash the sandblasted structural parts and apply adhesion promoter to the sandblasted surface;

[0045] S3: Screw the bracket 3 into the housing 1 so that the multi-petal buckle 12 of the bracket 3 engages with the multi-petal buckle mounting groove 11 of the housing 1. At the same time, insert the tool to ensure that the multi-petal buckle 12 of the bracket 3 and the multi-petal buckle mounting groove 11 of the housing are evenly spaced.

[0046] S4: Filling the gap between the housing 1 and the bracket 3 with the vulcanized damping material 2;

[0047] S5: Install the shock-absorbing damping pad 8 on the pressure plate 7;

[0048] S6: Install the pressure plate 7 on the housing 1 and fasten it with screws 9;

[0049] S7: Assemble the shock-absorbing pad 5 and the transducer 6 on the bracket 3;

[0050] S8: Install the sound-transmitting rubber 4 on the outer surface of the housing 1 and the bracket 3 on one side where the transducer 6 is installed.

[0051] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
