Description

Technical Field

[0001] The present invention relates to the field of underwater detection technology, and in particular to a shock absorbing mechanism, a sonar, and a sonar shock absorbing method. Background Art

[0002] In the prior art, sonars are typically screwed directly onto a submersible or vessel. For example, the unmanned submersible disclosed in Chinese Invention Patent Application Publication No. CN116859396A and the frame-mounted manta ray-like submersible disclosed in Chinese Utility Model Patent Application Grant No. CN216684808U both employ this technology. However, the drawback of screwing a sonar directly onto a submersible or vessel is that, when the submersible or vessel is struck or impacted, the vibration is transmitted to the sonar almost intactly, making it susceptible to vibration and reducing its detection accuracy. Summary of the Invention

[0008] As a further improvement to the technical solution of the present invention, the top clamping plate has a top through-hole, which is connected to the clamping cavity of the shock-absorbing platform, wherein the launch cabin of the sonar body extends to the outside of the shock-absorbing platform through the top through-hole of the top clamping plate.

[0009] As a further improvement to the technical solution of the present invention, the shock absorbing unit includes a bottom rubber pad and a top rubber pad, the bottom rubber pad is stacked on the bottom clamping plate and located in the clamping cavity of the shock absorbing platform, and the top rubber pad is stacked on the top clamping plate and located in the clamping cavity of the shock absorbing platform.

[0011] According to another aspect of the present invention, the present invention further provides a sonar vibration reduction method, wherein the vibration reduction method comprises the following steps: The high-frequency portion of the vibration generated when the mounting bracket is hit or impacted and transmitted toward the bottom plate of the mounting bracket is weakened by the rubber shock absorber; In the longitudinal direction, the low-frequency portion of the vibration transmitted toward the vibration-damping platform is weakened by a wire rope vibration damper provided between the bottom of the vibration-damping platform and the bottom plate of the mounting bracket; In the horizontal direction, the low-frequency part of the vibration transmitted toward the shock-absorbing platform is weakened by the wire rope shock absorber arranged between the side of the shock-absorbing platform and the support arm of the mounting bracket, thereby reducing the impact of the vibration on the sonar body installed on the shock-absorbing platform.

[0012] As a further improvement to the technical solution of the present invention, the shock absorption method further comprises the steps of: The high-frequency portion of the vibration transmitted toward the sonar body is weakened by the bottom rubber pad and the top rubber pad located between the sonar body and the shock-absorbing platform.

[0013] As a further improvement to the technical solution of the present invention, the two wire rope shock absorbers are symmetrically arranged between the bottom of the shock absorbing platform and the base plate of the mounting bracket, and the wire rope shock absorber arranged between one side of the shock absorbing platform and one of the support arms is symmetrical with the wire rope shock absorber arranged between the other side of the shock absorbing platform and the other support arm.

[0034] Reference is made to the accompanying drawings of the present invention. Figures 1 to 15 A sonar according to a preferred embodiment of the present invention will be disclosed and explained in the following description, wherein the sonar includes a shock absorbing mechanism 10 and a sonar body 20 installed on the shock absorbing mechanism 10. The shock absorbing mechanism 10 can be installed on a submersible or a hull. When the submersible or the hull is hit or impacted and vibrates, the shock absorbing mechanism 10 is used to reduce the impact of the vibration on the sonar body 20, thereby ensuring the detection accuracy of the sonar body 20.

[0035] It can be understood that the sonar body 20 includes a transmitting cabin 21 and a receiving cabin 22 installed with each other, the transmitting cabin 21 includes a transmitting transducer for generating and transmitting sound signals, and the receiving cabin 22 includes a receiving transducer for receiving the reflected sound signals and processing them, so that the sonar body 20 can realize the detection of the underwater environment.

[0036] Unlike the prior art, in order to reduce the impact of the vibration of the submersible or the hull on the detection accuracy of the sonar body 20, the present invention does not directly install the sonar body 20 on the submersible or the hull, but installs the sonar body 20 on the shock absorbing mechanism 10, and the shock absorbing mechanism 10 is installed on the submersible or the hull, so that when the submersible or the hull is hit or impacted and vibrates, the shock absorbing mechanism 10 can greatly reduce the impact of the vibration on the sonar body 20.

[0037] Specifically, the shock absorbing mechanism 10 includes an assembly bracket 11 , a shock absorbing platform 12 , a mounting bracket 13 and a shock absorbing unit 14 .

[0038] In a specific example of the sonar of the present invention, the assembly bracket 11 includes an assembly plate 111, and the assembly plate 111 can be directly or indirectly mounted on a submersible or a hull. For example, in a specific example of the sonar of the present invention, the assembly plate 111 can be mounted on a submersible or a hull via at least one screw 100.

[0039] The mounting bracket 13 includes a base plate 131 and two arms 132. The bottom of one arm 132 is set at one end of the base plate 131, so that the arm 132 extends upward from the end of the base plate 131. The bottom of the other arm 132 is set at the other end of the base plate 131, so that the arm 132 extends upward from the end of the base plate 131. In this way, the mounting bracket 13 forms a suspension cavity 133 between the base plate 131 and the two arms 132.

[0040] In one specific example of the sonar of the present invention, the base plate 131 and the two support arms 132 of the mounting bracket 13 are integrally formed. The base plate 131 is formed by bending a metal or alloy plate along a predetermined position, with the center portion of the plate forming the base plate 131. The two support arms 132 are formed at opposite ends of the plate, respectively, so that the two support arms 132 can extend upward from opposite ends of the base plate 131, forming the suspension cavity 133 between the base plate 131 and the two support arms 132. In another specific example of the sonar of the present invention, the bottoms of the two support arms 132 can be welded to opposite ends of the base plate 131, or the bottoms of the two support arms 132 can be screwed to opposite ends of the base plate 131 using the screws 100, so that the two support arms 132 can extend upward from opposite ends of the base plate 131, forming the suspension cavity 133 between the base plate 131 and the two support arms 132.

[0041] The shock absorbing unit 14 includes at least one rubber shock absorber 141 and multiple wire rope shock absorbers 142. The bottom plate 131 of the mounting bracket 13 is mounted on the assembly plate 111 of the assembly bracket 11 through at least one rubber shock absorber 141. The bottom of the shock absorbing platform 12 is mounted on the bottom plate 131 of the mounting bracket 13 through at least one wire rope shock absorber 142. One side of the shock absorbing platform 12 is mounted on one of the support arms 132 of the mounting bracket 13 through one of the wire rope shock absorbers 142. The other side of the shock absorbing platform 12 is mounted on the other support arm 132 of the mounting bracket 13 through one of the wire rope shock absorbers 142. In this way, the shock absorbing platform 12 is suspended in the suspension cavity 133 of the mounting bracket 13 by these wire rope shock absorbers 142. The sonar body 20 is installed on the shock absorbing platform 12 . Subsequently, the specific method of installing the sonar body 20 on the shock absorbing platform 12 will be disclosed in detail.

[0042] Since the assembly plate 111 of the assembly bracket 11 is mounted on the submersible or the hull by the screw 100 , when the submersible or the hull is hit or impacted and vibrates, the vibration is directly transmitted to the assembly bracket 11 , causing the assembly bracket 11 to vibrate. By arranging the rubber shock absorber 141 between the assembly plate 111 of the assembly bracket 11 and the bottom plate 131 of the mounting bracket 13, the rubber shock absorber 141 can weaken the high-frequency part of the vibration. By arranging at least one wire rope shock absorber 142 on the bottom plate 131 of the mounting bracket 13 and the bottom of the shock absorbing platform 12, the wire rope shock absorber 142 can weaken the low-frequency part of the vibration in the longitudinal direction. By arranging one wire rope shock absorber 142 on the support arm 132 of the mounting bracket 13 and the side of the shock absorbing platform 12, the wire rope shock absorber 142 can weaken the low-frequency part of the vibration in the horizontal direction. Therefore, the rubber shock absorber 141 and the wire rope shock absorber 142 can weaken the vibration to reduce the impact of the vibration on the sonar body 20 mounted on the shock absorbing platform 12, thereby ensuring the detection accuracy of the sonar body 20.

[0043] Preferably, in the attached Figures 1 to 15In the specific example of the sonar shown, the base plate 131 of the mounting bracket 13 is mounted to the assembly plate 111 of the assembly bracket 11 via three spaced-apart rubber dampers 141. Thus, the three rubber dampers 141 can stably suspend the mounting bracket 13 from the assembly plate 111 of the assembly bracket 11. More preferably, the line connecting the center of gravity of the triangle formed by the three rubber dampers 141 and the center of gravity of the assembly of the sonar body 20, the damping platform 12, the mounting bracket 13, and the wire rope dampers 142 is perpendicular to the horizontal plane.

[0044] Preferably, refer to the attached Figure 1 、 Figure 10 and Figure 12 The mounting bracket 13 can be fixedly mounted on the assembly bracket 11 through the screw 100 to prevent the mounting bracket 13 from moving horizontally relative to the assembly bracket 11.

[0045] Specifically, the mounting bracket 13 includes a mounting boss 134 having a first threaded hole 1341. The mounting boss 134 is protruding from the upper portion of the base plate 131. The assembly bracket 11 includes a baffle 112. The bottom of the baffle 112 is mounted on the assembly plate 111. For example, the bottom of the baffle 112 and the assembly plate 111 can be welded or screwed together, or the baffle 112 and the assembly plate 111 can be integrally formed by bending a metal plate or alloy plate along a predetermined position. The baffle 112 has a first screw hole 1121. After the base plate 131 of the mounting bracket 13 is mounted on the assembly plate 111 of the assembly bracket 11 through the three rubber shock absorbers 141, the baffle 112 is located on the outside of the base plate 131 of the mounting bracket 13 and the mounting boss 134, and the position of the first threaded hole 1341 of the mounting boss 134 corresponds to the position of the first screw hole 1121 of the baffle 112. The threaded end of one of the screw rods 100 extends to the first threaded hole 1341 of the mounting boss 134 after passing through the first screw hole 1121 of the baffle 112, and the threaded end of the screw rod 100 is screwed to the mounting boss 134. In this way, the mounting bracket 13 is fixedly mounted on the assembly bracket 11 through the screw rod 100, preventing the mounting bracket 13 from moving horizontally relative to the assembly bracket 11.

[0046] Reference Attachment Figure 5 、 Figure 8 、 Figure 10 and Figure 11The rubber shock absorber 141 includes a bottom shock absorbing portion 1411 and a top shock absorbing portion 1412, wherein the bottom shock absorbing portion 1411 includes a bottom shock absorbing tube 14111 and a bottom insert portion 14112 extending upward from the bottom shock absorbing tube 14111, and the top shock absorbing portion 1412 includes a top shock absorbing tube 14121 and a top insert portion 14122 extending downward from the top shock absorbing tube 14121, wherein the assembly plate 111 of the assembly bracket 11 has at least one second screw hole 1111, and the mounting bracket 13 The bottom plate 131 has at least one second threaded hole 1311, wherein the outer diameter of the bottom shock absorbing tube 14111 of the bottom shock absorbing portion 1411 is larger than the inner diameter of the second screw hole 1111 of the assembly plate 111, and the outer diameter of the bottom inserting portion 14112 is consistent with the inner diameter of the second screw hole 1111 of the assembly plate 111. The bottom shock absorbing tube 14111 is stacked on the bottom of the assembly plate 111, and the bottom inserting portion 14112 is inserted into the second screw hole 1111 of the assembly plate 111. , the outer diameter of the top shock absorbing tube 14121 of the top shock absorbing portion 1412 is larger than the inner diameter of the second screw hole 1111 of the assembly plate 111, the outer diameter of the top insertion portion 14122 is consistent with the inner diameter of the second screw hole 1111 of the assembly plate 111, the top shock absorbing tube 14121 is stacked on the top of the assembly plate 111, the top insertion portion 14122 is inserted into the second screw hole 1111 of the assembly plate 111, and the bottom plate 131 is set on the top shock absorbing portion 1 Above the top shock-absorbing cylinder 14121 of 412, the threaded end of one of the screw rods 100 extends to the second threaded hole 1311 of the bottom shock-absorbing part 1411 and the top shock-absorbing cylinder 14121 of the top shock-absorbing part 1412 respectively, and the threaded end of the screw rod 100 is screwed to the bottom plate 131, so that the bottom plate 131 of the mounting bracket 13 is mounted on the assembly plate 111 of the assembly bracket 11 through the rubber shock absorber 141.

[0047] Reference Attachment Figure 11 and Figure 12The bottom shock absorbing part 1411 isolates the screw 100 and the assembly plate 111 of the assembly bracket 11, and the top shock absorbing part 1412 isolates the bottom plate 131 of the mounting bracket 13 and the assembly plate 111, as well as isolates the screw 100 and the assembly plate 111. The edge of the assembly plate 111 for forming the second screw hole 1111 is clamped between the bottom shock absorbing cylinder 14111 of the bottom shock absorbing part 1411 and the top shock absorbing cylinder 14121 of the top shock absorbing part 1412. In this way, the rubber shock absorber 141 can effectively weaken the high-frequency part of the vibration, and reduce the influence of the high-frequency part of the vibration on the mounting bracket 13 and the shock absorbing platform 12 mounted on the mounting bracket 13.

[0048] It can be understood that three of the screws 100 are used to mount the bottom plate 131 of the mounting bracket 13 on the assembly plate 111 of the assembly bracket 11, and one of the screws 100 is used to mount the mounting boss 134 of the mounting bracket 13 on the baffle 112 of the assembly bracket 11. Since the mounting boss 134 of the mounting bracket 13 and the bottom plate 131 are fixed, and the baffle 112 of the assembly bracket 11 and the assembly plate 111 are fixed, the mounting bracket 13 and the assembly bracket 11 are also fixed. Fixed, at the same time, since the bottom shock absorbing part 1411 isolates the screw 100 and the assembly plate 111 of the assembly bracket 11, the top shock absorbing part 1412 isolates the bottom plate 131 of the mounting bracket 13 and the assembly plate 111 of the assembly bracket 11, and isolates the screw 100 and the assembly plate 111, the rubber shock absorber 141 can effectively weaken the high-frequency part of the vibration, and reduce the influence of the high-frequency part of the vibration on the mounting bracket 13 and the shock absorbing platform 12 installed on the mounting bracket 13.

[0049] Preferably, continue to refer to the attached Figure 4 、 Figure 5 、 Figure 8 、 Figure 10 and Figure 11The rubber shock absorber 141 further includes a metal connecting piece 1413 and a metal gasket 1414. The connecting piece 1413 includes a connecting tube 14131 and a connecting ring 14132 extending outward from the bottom of the connecting tube 14131, that is, the outer diameter of the connecting ring 14132 is larger than the outer diameter of the connecting tube 14131, and the metal gasket 1414 has a gasket through-hole 14141. The inner diameter of the metal gasket 1414 is smaller than or equal to the inner diameter of the connecting tube 14131, wherein the top of the connecting tube 14131 is abutted against and stacked on the top shock absorber tube 1412 after passing through the bottom shock absorber tube 14111 and the top shock absorber tube 14121. 1, the metal gasket 1414 of the bottom shock absorbing part 14111, the connecting ring 14132 is stacked on the bottom shock absorbing tube 14111, and the threaded end of the screw rod 100 extends to the second threaded hole 1311 of the bottom plate 131 of the mounting bracket 13 after passing through the connecting tube 14131 and is screwed to the bottom plate 131. In this way, in the process of screwing the threaded end of the screw rod 100 to the bottom plate 131 of the mounting bracket 13, the connecting piece 1413 and the metal gasket 1414 can prevent the bottom shock absorbing part 1411 and the top shock absorbing part 1412 from being excessively compressed and causing fracture, thereby ensuring that the bottom shock absorbing part 1411 and the top shock absorbing part 1412 have good shock absorbing effect.

[0050] That is to say, the connecting member 1413 and the metal gasket 1414 cooperate with each other, which can not only prevent the bottom shock absorbing part 1411 and the top shock absorbing part 1412 from being over-compressed, but also control the compression amount of the bottom shock absorbing part 1411 and the top shock absorbing part 1412, ensuring that the bottom shock absorbing part 1411 and the top shock absorbing part 1412 have good shock absorbing effect.

[0051] Preferably, in the attached Figures 1 to 15In this specific example of the sonar shown, the bottom of the shock absorbing platform 12 is mounted on the bottom plate 131 of the mounting bracket 13 through two steel wire rope shock absorbers 142, and the positions of the two steel wire rope shock absorbers 142 are symmetrical to each other. The center of gravity of the triangle formed by the three rubber shock absorbers 141 and the center of gravity of the assembly of the sonar body 20, the shock absorbing platform 12, the mounting bracket 13 and these steel wire rope shock absorbers 142 intersect with the symmetry axis of the two steel wire rope shock absorbers 142. One side of the shock absorbing platform 12 is mounted on one of the support arms 132 of the mounting bracket 13 through one of the steel wire rope shock absorbers 142, and the other side of the shock absorbing platform 12 is mounted on the other support arm 132 of the mounting bracket 13 through one of the steel wire rope shock absorbers 142, and is used to connect the shock absorbing platform 12 to the bottom plate 131 of the mounting bracket 13. The position of the wire rope shock absorber 142 on one side of the shock absorbing platform 12 and one of the support arms 132 is symmetrical to the position of the wire rope shock absorber 142 used to connect the other side of the shock absorbing platform 12 and the other support arm 132. The line connecting the center of gravity of the triangle formed by the three rubber shock absorbers 141 and the center of gravity of the assembly of the sonar body 20, the shock absorbing platform 12, the mounting bracket 13 and these wire rope shock absorbers 142 intersects with the symmetry axis of the two wire rope shock absorbers 142. In this way, these wire rope shock absorbers 142 cooperate with each other to suspend the shock absorbing platform 12 in the suspension cavity 133 of the mounting bracket 13, and to weaken the low-frequency part of the vibration, so as to reduce the influence of the vibration on the sonar body 20 mounted on the shock absorbing platform 12, thereby ensuring the detection accuracy of the sonar body 20.

[0052] The structure of the wire rope shock absorber 142 is as follows Figure 15As shown, the wire rope shock absorber 142 includes a first extension arm 1421, a second extension arm 1422 and a wire rope spiral 1423, the first extension arm 1421 has a row of first arm body through-holes 14211, the second extension arm 1422 has a row of second arm body through-holes 14221, the first extension arm 1421 and the second extension arm 1422 are symmetrically and spaced apart from each other, the positions of each first arm body through-hole 14211 of the first extension arm 1421 and the positions of each second arm body through-hole 14221 of the second extension arm 1422 correspond one to one, the wire rope spiral 1423 alternately passes through each first arm body through-hole 14211 of the first extension arm 1421 and the second arm body through-hole 14221 of the second extension arm 1422 in sequence, so that the first extension arm 1421 and the second extension arm 1422 are connected by the wire rope spiral 1423. Since the wire rope spiral 1423 extends spirally between the first extension arm 1421 and the second extension arm 1422, the wire rope spiral 1423 is elastic. After the first extension arm 1421 and the second extension arm 1422 are pressed and moved closer to each other, the wire rope spiral 1423 is deformed and accumulates elastic potential energy. After the pressure applied to the first extension arm 1421 and the second extension arm 1422 is removed, the wire rope spiral 1423 returns to its original state and resets the first extension arm 1421 and the second extension arm 1422.

[0053] The first extension arms 1421 of the two wire rope shock absorbers 142 can be fixedly mounted on the bottom plate 131 of the mounting bracket 13 via the screw rod 100, and the second extension arms 1422 can be fixedly mounted on the bottom of the shock absorbing platform 12 via the screw rod 100. In this way, the bottom of the shock absorbing platform 12 is mounted on the bottom plate 131 via the wire rope shock absorbers 142.

The threaded ends of the two screws 100 respectively pass through the pair of third screw holes 1312 of the base plate 131 and extend to the two third threaded holes 14212 of the first extension arm 1421 of the wire rope shock absorber 142 and are screwed with the first extension arm 1421, so that the first extension arm 1421 of the wire rope shock absorber 142 is fixedly mounted on the base plate 131 through the screw 100. The opposite ends of the second extension arm 1422 of the wire rope shock absorber 142 respectively have a fourth screw hole 14222, and the bottom of the shock absorber platform 12 has two pairs of fourth threaded holes 1201. The positions of the two fourth screw holes 14222 of the second extension arm 1422 of a wire rope shock absorber 142 correspond one to one with the positions of a pair of fourth threaded holes 1201 of the shock absorber platform 12. The threaded ends of the two screws 100 extend to the two fourth threaded holes 1201 of the shock absorber platform 12 after passing through the two fourth screw holes 14222 of the second extension arm 1422 of the wire rope shock absorber 142 respectively and are screwed to the shock absorber platform 12, so that the second extension arm 1422 of the wire rope shock absorber 142 is fixedly mounted on the shock absorber platform 12 through the screw 100.

[0054] The first extension arm 1421 of one of the wire rope shock absorbers 142 can be fixedly mounted on one of the support arms 132 of the mounting bracket 13 through the screw 100, and the second extension arm 1422 can be fixedly mounted on one side of the shock absorbing platform 12 through the screw 100. The first extension arm 1421 of another of the wire rope shock absorbers 142 can be fixedly mounted on the other support arm 132 of the mounting bracket 13 through the screw 100, and the second extension arm 1422 can be fixedly mounted on the other side of the shock absorbing platform 12 through the screw 100. In this way, the opposite sides of the shock absorbing platform 12 are respectively mounted on each of the support arms 132 of the mounting bracket 13 through a wire rope shock absorber 142. Specifically, the support arm 132 of the mounting bracket 13 has a pair of fifth screw holes 1321, and the side of the shock absorbing platform 12 has a pair of fifth threaded holes 1202, wherein the positions of the two third threaded holes 14212 of the first extension arm 1421 of the wire rope shock absorber 142 correspond to the positions of the pair of fifth screw holes 1321 of the support arm 132, and the threaded ends of the two screws 100 extend to the two third threaded holes 14212 of the first extension arm 1421 of the wire rope shock absorber 142 after respectively passing through the two fifth screw holes 1321 of the support arm 132 of the mounting bracket 13 and are screwed to the first extension arm 1421, so that the first extension arm of the wire rope shock absorber 142 1421 is fixedly mounted on the support arm 132 of the mounting bracket 13 through the screw 100, wherein the positions of the two fourth screw holes 14222 of the second extension arm 1422 of the wire rope shock absorber 142 correspond one to one with the positions of the two fifth threaded holes 1202 of the shock absorber platform 12, and the threaded ends of the two screws 100 extend to the two fifth threaded holes 1202 of the shock absorber platform 12 after respectively passing through the two fourth screw holes 14222 of the second extension arm 1422 of the wire rope shock absorber 142 and are screwed to the shock absorber platform 12, so that the second extension arm 1422 of the wire rope shock absorber 142 is fixedly mounted on the side of the shock absorber platform 12 through the screw 100.

[0055] Through the above structure, these wire rope shock absorbers 142 cooperate with each other to suspend the shock absorbing platform 12 in the suspension cavity 133 of the mounting bracket 13, and are used to weaken the low-frequency part of the vibration to reduce the impact of the vibration on the sonar body 20 installed on the shock absorbing platform 12, thereby ensuring the detection accuracy of the sonar body 20.

[0056] Preferably, the first extension arm 1421 and the second extension arm 1422 of the two wire rope shock absorbers 142 arranged between the bottom of the shock absorbing platform 12 and the base plate 131 of the mounting bracket 13 extend in a front-to-back direction, and the first extension arm 1421 and the second extension arm 1422 of the two wire rope shock absorbers 142 arranged between the opposite sides of the shock absorbing platform 12 and each support arm 132 of the mounting bracket 13 extend in an up-down direction.

[0057] Reference Attachment Figure 1 、 Figure 4 and Figure 5 The shock absorbing platform 12 has a clamping cavity 121, an escape opening 122, and a cable channel 123. The escape opening 122 and the cable channel 123 are respectively connected to the clamping cavity 121. At least a portion of the sonar body 20 is clamped in the clamping cavity 121 of the shock absorbing platform 12. The escape opening 122 of the shock absorbing platform 12 corresponds to the receiving transducer of the receiving compartment 22 of the sonar body 20. The cable of the sonar body 20 extends outward through the cable channel 123 of the shock absorbing platform 12. In this way, the sonar body 20 can be securely mounted on the shock absorbing platform 12.

[0058] Specifically, the shock absorbing platform 12 includes a bottom clamping plate 124 and a top clamping plate 125. The bottom clamping plate 124 and the top clamping plate 125 are mounted on each other to form the clamping cavity 121, the avoidance opening 122, and the cable channel 123 of the shock absorbing platform 12 between the bottom clamping plate 124 and the top clamping plate 125. The sonar body 20 is clamped in the clamping cavity 121 of the shock absorbing platform 12 by the bottom clamping plate 124 and the top clamping plate 125 to install the sonar body 20 on the shock absorbing platform 12. Optionally, in other examples of the sonar of the present invention, the avoidance opening 122 and the cable channel 123 of the shock absorbing platform 12 can be formed in the bottom clamping plate 124, or the avoidance opening 122 and the cable channel 123 of the shock absorbing platform 12 can be formed in the bottom clamping plate 124, or one of the avoidance opening 122 and the cable channel 123 of the shock absorbing platform 12 is formed in the bottom clamping plate 124, and the other is formed in the top clamping plate 125 or between the bottom clamping plate 124 and the top clamping plate 125.

[0059] More specifically, please refer to the attached Figures 1 to 5The bottom clamping plate 124 includes a bottom plate body 1241 and two bottom retaining walls 1242, and the bottom clamping plate 124 has a bottom notch 1243. The two bottom retaining walls 1242 extend upward from the rear side of the bottom plate body 1241 in a mutually spaced manner. The bottom notch 1243 is formed between the two bottom retaining walls 1242. For example, the two bottom retaining walls 1242 can respectively extend upward from the rear side of the bottom plate body 1241 as a whole. Correspondingly, the top clamping plate 125 includes a top plate body 1251 and two top retaining walls 1252, and the top clamping plate 125 has a top notch 1253, and the two top retaining walls 1252 extend downward from the rear side of the top plate body 1251 in a mutually spaced manner, and the top notch 1253 is formed between the two top retaining walls 1252. For example, the two top retaining walls 1252 can respectively extend downward from the rear side of the top plate body 1251 as a whole. The two bottom retaining walls 1242 and the two top retaining walls 1252 are installed to each other in a face-to-face manner between the bottom plate 1241 and the top plate 1251 to realize the installation of the bottom clamping plate 124 and the top clamping plate 125, wherein the position of the bottom notch 1243 of the bottom clamping plate 124 corresponds to the position of the top notch 1253 of the top clamping plate 125 to form the cable channel 123 of the shock absorbing platform 12, and the shock absorbing platform 12 forms the clamping cavity 121 between the bottom plate 1241 of the bottom clamping plate 124 and the top plate 1251 of the top clamping plate 125, and forms the avoidance opening 122 on the front side of the bottom plate 1241 and the front side of the top plate 1251.

[0060] Reference Attachment Figure 8 and Figure 9The two bottom retaining walls 1242 of the bottom retaining plate 124 and the two top retaining walls 1252 of the top retaining plate 125 can be installed by the screw 100, so that the bottom retaining plate 124 and the top retaining plate 125 are reliably installed. Specifically, the bottom holding wall 1242 of the bottom clamping plate 124 has at least one sixth screw hole 12421, and the top holding wall 1252 of the top clamping plate 125 has at least one sixth threaded hole 12521. The position of the sixth threaded hole 12521 of the top holding wall 1252 corresponds to the position of the sixth screw hole 12421 of the bottom holding wall 1242. The threaded end of the screw 100 extends to the sixth threaded hole 12521 of the top holding wall 1252 after passing through the sixth screw hole 12421 of the bottom holding wall 1242 and is screwed to the top holding wall 1252, so that the bottom holding wall 1242 and the top holding wall 1252 are installed by the screw 100.

[0061] Preferably, the two bottom retaining walls 1242 of the bottom clamping plate 124 are respectively arranged at the two corners of the bottom plate body 1241, and the two top retaining walls 1252 of the top clamping plate 125 are respectively arranged at the two corners of the top plate body 1251, so that when the sonar body 20 is clamped in the clamping cavity 121 by the bottom clamping plate 124 and the top clamping plate 125, the two bottom retaining walls 1242 of the bottom clamping plate 124 and the two top retaining walls 1252 of the top clamping plate 125 cooperate with each other to prevent the sonar body 20 from moving laterally, so as to ensure the reliability of the sonar.

[0062] Preferably, refer to the attached Figure 5 The top clamping plate 125 has a top through-hole 1254, which is connected to the clamping cavity 121 of the shock absorbing platform 12. The transmitting cabin 21 of the sonar body 20 can extend to the outside of the shock absorbing platform 12 through the top through-hole 1254 of the top clamping plate 125. In this way, the sonar can avoid the shock absorbing mechanism 10 blocking the sound signal emitted by the transmitting cabin 21 of the sonar body 20.

[0063] Continue to refer to the attached Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 、 Figure 10 and Figure 13The shock absorbing unit 14 further includes a bottom rubber pad 143 and a top rubber pad 144. The bottom rubber pad 143 is stacked on the bottom clamping plate 124 and is located in the clamping cavity 121 of the shock absorbing platform 12. The top rubber pad 144 is stacked on the top clamping plate 125 and is located in the clamping cavity 121 of the shock absorbing platform 12. When clamped in the clamping cavity 121 of the shock-absorbing platform 12, the sonar body 20 and the bottom clamping plate 124 compress the bottom rubber pad 143, i.e., the bottom rubber pad 143 isolates the sonar body 20 from the bottom clamping plate 124. Meanwhile, the sonar body 20 and the top clamping plate 125 compress the top rubber pad 144, i.e., the top rubber pad 144 isolates the sonar body 20 from the top clamping plate 125. In this manner, the high-frequency portion of vibration can be further attenuated by the bottom rubber pad 143 and the top rubber pad 144, thereby reducing the impact of vibration on the sonar body 20 mounted on the shock-absorbing platform 12, thereby ensuring the detection accuracy of the sonar body 20.

[0064] Preferably, refer to the attached Figure 6 、 Figure 8 、 Figure 10 and Figure 13 The top rubber pad 144 has a pad boss 1441 and a rubber pad through-hole 1442. The pad boss 1441 protrudes into the top through-hole 1254 of the top clamping plate 125. The top of the launch module 21 of the sonar body 20 passes through the rubber pad through-hole 1442 of the top rubber pad 144. In this way, the top rubber pad 144 can completely isolate the sonar body 20 from the top clamping plate 125. Preferably, the outer diameter of the pad boss 1441 of the top rubber pad 144 is consistent with the inner diameter of the top through-hole 1254 of the top clamping plate 125.

[0065] Preferably, refer to the attached Figure 4 and Figure 5The bottom plate 1241 of the bottom clamping plate 124 has two seventh threaded holes 12411, the front side of the top plate 1251 of the top clamping plate 125 has two seventh screw holes 12511, and the sonar body 20 has two body through-holes 23. When the bottom clamping plate 124 and the top clamping plate 125 clamp the sonar body 20 in the clamping cavity 121 of the shock absorbing platform 12, the positions of the two seventh threaded holes 12411 of the bottom plate 1241, the positions of the two body through-holes 23 of the sonar body 20, and the The positions of the two seventh screw holes 12511 of the top plate 1251 correspond to each other one by one. The threaded ends of the two screws 100 respectively pass through the two seventh screw holes 12511 of the top plate 1251 and the two body through-holes 23 of the sonar body 20 in sequence, and then extend to the two seventh threaded holes 12411 of the bottom plate 1241 and are screwed onto the bottom plate 1241 respectively, thereby preventing the sonar body 20 from rotating in the clamping cavity 121 of the shock absorbing platform 12, so as to ensure that the sonar body 20 is reliably mounted on the shock absorbing platform 12.

[0066] Preferably, the bottom rubber pad 143 has two bottom pad through-holes 1431, the top rubber pad 144 has two top pad through-holes 1443, the positions of the two seventh threaded holes 12411 of the bottom plate 1241, the positions of the two bottom pad through-holes 1431 of the bottom rubber pad 143, the positions of the two body through-holes 23 of the sonar body 20, the positions of the two top pad through-holes 1443 of the top rubber pad 144 and the positions of the two seventh screw holes 12511 of the top plate 1251 correspond to each other. The threaded end of the screw 100 extends to the two seventh screw holes 12411 of the bottom plate 1241 and is screwed onto the bottom plate 1241 respectively after passing through the two seventh screw holes 12511 of the top plate 1251, the two seventh screw holes 12511 of the top plate 1251, the two body through-holes 23 of the sonar body 20, and the two bottom pad through-holes 1431 of the bottom rubber pad 143. In this way, the sonar can avoid misalignment between the bottom rubber pad 143 and the top rubber pad 144.

[0067] The assembly process of the sonar of the present invention is as follows: Step S1, installing the sonar body 20 on the shock-absorbing platform 12; Step S2, suspending the shock-absorbing platform 12 in the suspension cavity 133 of the mounting bracket 13 via the wire rope shock absorber 142; Step S3, installing the mounting bracket 13 on the assembly plate 111 of the assembly bracket 11 via the rubber shock absorber 141; Step S4, allowing the screw 100 to lock the assembly bracket 11 and the mounting bracket 13 to complete the assembly of the sonar. In this way, when the assembly bracket 11 is hit or impacted to generate vibration or the vibration is transmitted to the assembly bracket 11, the rubber shock absorber 141 weakens the high-frequency portion of the vibration, and the wire rope shock absorber 142 weakens the low-frequency portion of the vibration. This can reduce the impact of the vibration on the sonar body 20, thereby ensuring the detection accuracy of the sonar body 20.

[0068] In step S1, first, the receiving cabin 22 of the sonar body 20 is placed on the bottom rubber pad 143 of the bottom plate 1241 stacked on the bottom clamping plate 124. At this time, the bottom rubber pad 143 isolates the sonar body 20 and the bottom clamping plate 124, the receiving transducer of the receiving cabin 22 of the sonar body 20 faces the front side of the bottom clamping plate 124, and the cable of the sonar body 20 is located in the bottom groove 1243 of the bottom clamping plate 124. Secondly, the top clamping plate 125 is arranged above the bottom clamping plate 124 in a manner that allows the top of the launch cabin 21 of the sonar body 20 to pass through the rubber pad through-hole 1442 of the top rubber pad 144. At this time, the top rubber pad 144 isolates the sonar body 20 and the top clamping plate 125, and each of the top retaining walls 1252 of the top clamping plate 125 is respectively located above each of the bottom retaining walls 1242 of the bottom clamping plate 124. Next, the screw 100 is allowed to lock each of the bottom retaining walls 1242 of the bottom clamping plate 124 and each of the top retaining walls 1252 of the top clamping plate 125. During this process, the sonar body 20 and the bottom plate 1241 of the bottom clamping plate 124 apply pressure to the bottom rubber pad 143, compressing the bottom rubber pad 143. The sonar body 20 and the top plate 1251 of the top clamping plate 125 apply pressure to the top rubber pad 144, compressing the top rubber pad 144. Preferably, step S1 further includes the step of allowing the threaded end of the screw 100 to extend to the seventh threaded hole 12411 of the bottom plate 1241 after sequentially passing through the seventh screw hole 12511 of the top plate 1251 and the body through-hole 23 of the sonar body 20, thereby being screwed onto the bottom plate 1241.

[0069] In step S2, first, the second extension arms 1422 of the two wire rope shock absorbers 142 are fixedly installed on the bottom of the shock absorbing platform 12 through the screw 100, the second extension arm 1422 of one wire rope shock absorber 142 is fixedly installed on one side of the shock absorbing platform 12 through the screw 100, and the second extension arm 1422 of the other wire rope shock absorber 142 is fixedly installed on the other side of the shock absorbing platform 12 through the screw 100. Secondly, the first extension arms 1421 of the two wire rope shock absorbers 142 fixedly installed on the bottom of the shock absorbing platform 12 are fixedly installed on the bottom plate 131 of the mounting bracket 13 through the screw 100, the first extension arm 1421 of the wire rope shock absorber 142 fixedly installed on one side of the shock absorbing platform 12 is fixedly installed on one support arm 132 of the mounting bracket 13 through the screw 100, and the first extension arm 1421 of the wire rope shock absorber 142 fixedly installed on the other side of the shock absorbing platform 12 is fixedly installed on the other support arm 132 of the mounting bracket 13 through the screw 100. In this way, these wire rope shock absorbers 142 cooperate with each other to suspend the shock absorbing platform 12 in the suspension cavity 133 of the mounting bracket 13. Preferably, the two wire rope shock absorbers 142 located between the bottom of the shock absorbing platform 12 and the bottom plate 131 of the mounting bracket 13 are in a compressed state.

[0070] In step S3, first, the top shock-absorbing cylinder 14121 is stacked above the assembly plate 111 in such a manner that the top insertion portion 14122 of the top shock-absorbing portion 1412 is inserted into the second screw hole 1111 of the assembly plate 111 of the assembly bracket 11, and the bottom shock-absorbing cylinder 14111 is stacked below the assembly plate 111 in such a manner that the bottom insertion portion 14112 of the bottom shock-absorbing portion 1411 is inserted into the second screw hole 1111 of the assembly plate 111 of the assembly bracket 11. Next, the connecting ring 14132 of the connecting member 1413 is stacked on the bottom shock-absorbing cylinder 14111 in such a manner that the top of the connecting cylinder 14131 of the connecting member 1413 penetrates the bottom shock-absorbing cylinder 14111 and the top shock-absorbing cylinder 14121. Third, the bottom plate 131 of the mounting bracket 13 is placed above the top shock-absorbing tube 14121 of the top shock-absorbing portion 1412 of the rubber shock absorbers 141. Fourth, the threaded end of the screw rod 100 is allowed to extend into the second threaded hole 1311 of the bottom plate 131 after passing through the connecting tube 14131 of the connecting member 1413, and the threaded end of the screw rod 100 is screwed onto the bottom plate 131. In this way, the rubber shock absorbers 141 suspend the mounting bracket 13 above the assembly plate 111 of the assembly bracket 11.

[0071] In step S4, the threaded end of the screw 100 is allowed to extend to the first threaded hole 1341 of the mounting boss 134 of the mounting bracket 13 after passing through the first screw hole 1121 of the baffle 112 of the assembly bracket 11, so as to fixedly mount the mounting bracket 13 on the assembly bracket 11.

[0072] According to another aspect of the present invention, the present invention further provides a sonar vibration reduction method, wherein the vibration reduction method comprises the following steps: The rubber shock absorber 141 weakens the high-frequency portion of the vibration generated when the assembly bracket 11 is hit or impacted and transmitted toward the bottom plate 131 of the mounting bracket 13; In the longitudinal direction, the low-frequency portion of the vibration transmitted toward the vibration-damping platform 12 is weakened by the wire rope vibration damper 142 disposed between the bottom of the vibration-damping platform 12 and the bottom plate 131 of the mounting bracket 13; In the horizontal direction, the low-frequency part of the vibration transmitted toward the shock absorbing platform 12 is weakened by the wire rope shock absorber 142 arranged between the side of the shock absorbing platform 12 and the support arm 132 of the mounting bracket 13, thereby reducing the impact of the vibration on the sonar body 20 installed on the shock absorbing platform 12.
