Abstract
Description
Technical Field
[0001] The utility model relates to a shock absorbing device, in particular to a shock absorbing device used for sonar. Background Art
[0002] Sonar is widely used in many fields, including ocean exploration and marine resource development. It detects underwater targets and maps the seabed by emitting sound waves and receiving reflected waves. The accuracy and reliability of sonar detection results are directly related to the effectiveness and safety of related operations. In the prior art, sonars are directly mounted on ships or submarines, which inevitably makes them susceptible to vibration interference during actual use. That is, vibrations from ships or submarines are directly transmitted to the sonar, which has many negative effects on its performance. For example, high-frequency vibrations can cause resonance in compact components such as the sonar's transducer, resulting in a shift in the transducer's operating frequency, reducing the sonar's detection accuracy and resolution. Low-frequency vibrations can destabilize the sonar's overall structure, causing the sonar's emitted beam to be uneven, leading to deviations or even errors in detection results. Therefore, how to effectively filter out high- and low-frequency vibrations is a technical problem that the inventors of the present utility model have been committed to solving.

[0036] Refer to the specification of this utility model Figures 1 to 6 In the following description, a shock absorbing device 10 according to a preferred embodiment of the present invention will be disclosed and explained, wherein the shock absorbing device 10 is used to install a sonar 20 on a ship or a submarine 30, so as to reduce the influence of the vibration of the ship or the submarine 30 on the detection accuracy of the sonar 20.
[0037] Specifically, the shock absorbing device 10 includes a bottom plate 11, a top plate 12, a plurality of shock absorbing support assemblies 13, and a hoisting rod 14. The bottom of each shock absorbing support assembly 13 is mounted on the bottom plate 11, and the top of each shock absorbing support assembly 13 is mounted on the top plate 12. The sonar 20 is mounted on the top plate 12 and is located in the space between the bottom plate 11 and the top plate 12. The bottom of the hoisting rod 14 is mounted on the bottom plate 11, and the top of the hoisting rod 14 is mounted on the ship or submersible 30. In this way, the shock absorbing device 10 is used to mount the sonar 20 on the ship or submersible 30. When the ship or submersible 30 vibrates and the vibration is transmitted to the bottom plate 11 through the hoisting rod 14, the shock absorbing support assembly 13 is used to weaken the vibration, thereby reducing the impact of the vibration on the detection accuracy of the sonar 20.
[0038] Continue to refer to the attached Figures 1 to 6The shock-absorbing support assembly 13 includes a bottom pad 131 , a wire rope shock absorber 132 , a top pad 133 , at least one rubber shock absorber 134 and a support arm 135 . The bottom pad 131 and the top pad 133 are respectively installed on the bottom and top of the wire rope shock absorber 132. Specifically, the wire rope shock absorber 132 includes a base frame 1321, a top frame 1322 located above the base frame 1321, and a wire rope spiral 1323 arranged between the base frame 1321 and the top frame 1322. The shock absorbing device 10 includes a plurality of screws 15. The bottom pad 131 is installed on the base frame 1321 through two of the screws 15 to install the bottom pad 131 on the wire rope shock absorber 132. The top pad 133 is installed on the top frame 1322 through two of the screws 15 to install the top pad 133 on the wire rope shock absorber 132. The rubber shock absorber 134 is installed at the bottom of the top pad 133 and the support arm 135, and is used to suspend the support arm 135 above the top pad 133, that is, the rubber shock absorber 134 isolates the top pad 133 and the support arm 135 to avoid direct contact between the top pad 133 and the support arm 135.
[0039] The bottom pad 131 is mounted on the bottom plate 11 to mount the bottom of the shock-absorbing support assembly 13 on the bottom plate 11. For example, in a specific example of the shock-absorbing device 10 of the present invention, the bottom pad 131 can be mounted on the bottom plate 11 by two or more of the screws 15. The top of the support arm 135 is mounted on the top plate 12 to mount the top of the shock-absorbing support assembly 13 on the top plate 12. For example, in a specific example of the shock-absorbing device 10 of the present invention, the top of the support arm 135 can be mounted on the top plate 12 by two or more of the screws 15. It can be understood that the bottom of the lifting rod 14 can also be mounted on the bottom plate 11 by a group of the screws 15, and the top of the lifting rod 14 can be mounted on the ship or submersible 30 by a group of the screws 15.
[0040] When the ship or underwater vehicle 30 vibrates and the vibration is transmitted to the base plate 11 through the lifting rod 14, the wire rope shock absorber 132 of the shock-absorbing support assembly 13 can weaken the low frequency of the vibration, and the rubber shock absorber 134 can weaken the high frequency of the vibration. In this way, the shock absorbing device 10 effectively weakens the vibration and reduces the impact of the vibration on the detection accuracy of the sonar 20.
[0041] Furthermore, in the attached Figures 1 to 6In this specific example of the shock absorbing device 10 shown, there is an ear 1351 on each of the opposite sides of the bottom of the support arm 135, and the number of the rubber shock absorbers 134 is two, one rubber shock absorber 134 is installed on one end of the top pad 133 and one ear 1351 of the support arm 135, and the other rubber shock absorber 134 is installed on the other end of the top pad 133 and the other ear 1351 of the support arm 135. In this way, on the one hand, it is convenient to assemble the shock absorbing support assembly 13, and on the other hand, the two rubber shock absorbers 134 cooperate with each other to prevent the support arm 135 from tilting relative to the top pad 133, and the two rubber shock absorbers 134 can provide better shock absorbing effect.
[0042] Reference Attachment Figure 4 The support arm 135 is provided with an ear through-hole 1352 on each second ear portion 1351. The rubber shock absorber 134 includes a bottom shock absorber 1341 and a top shock absorber 1342. The bottom shock absorber 1341 has a first through-hole 13411, and the top shock absorber 1342 has a second through-hole 13421. The top of the bottom shock absorber 1341 is inserted from bottom to top into the ear through-hole 1352 of the support arm 135. 2 is inserted into the ear through-hole 1352 of the support arm 135 from top to bottom, and the threaded end of the screw 15 passes through the second through-hole 13421 of the top shock absorber 1342 and the first through-hole 13411 of the bottom shock absorber 1341 in sequence and is screwed onto the top pad 133. In this way, the bottom of the rubber shock absorber 134 is mounted on the top pad 133, and the middle part of the rubber shock absorber 134 is mounted on the ear 1351 of the support arm 135. It can be understood that the bottom shock absorber 1341 isolates the top pad 133 and the support arm 135 to avoid direct contact between the top pad 133 and the support arm 135, and the bottom shock absorber 1341 isolates the screw 15 and the support arm 135, and the top shock absorber 1342 isolates the screw 15 and the support arm 135, so that the rubber shock absorber 134 can effectively weaken the high frequency in the vibration.
[0043] In other words, the bottom shock absorber 1341 and the top shock absorber 1342 of the rubber shock absorber 134 are two independent rubber parts, wherein the outer diameter of the top of the bottom shock absorber 1341 is not larger than the inner diameter of the ear perforation 1352 of the support arm 135, and the outer diameter of the bottom of the bottom shock absorber 1341 is larger than the inner diameter of the ear perforation 1352 of the support arm 135. In this way, after the top of the bottom shock absorber 1341 is inserted into the ear perforation 1352 of the support arm 135, the bottom of the bottom shock absorber 1341 can be overlapped with the ear 1351 of the support arm 135. , which is subsequently used to isolate the support arm 135 and the top pad 133, wherein the outer diameter of the bottom of the top shock absorber 1342 is not larger than the inner diameter of the ear perforation 1352 of the support arm 135, and the outer diameter of the top of the top shock absorber 1342 is larger than the inner diameter of the ear perforation 1352 of the support arm 135. In this way, after the bottom of the top shock absorber 1342 is inserted into the ear perforation 1352 of the support arm 135, the top of the top shock absorber 1342 is superimposed on the ear 1351 of the support portion 135, and is subsequently used to isolate the screw 15 and the support arm 135.
[0044] The rubber shock absorber 134 further includes a metal gasket 1343 and a metal connecting piece 1344, wherein the gasket 1343 has a gasket through-hole 13431, the gasket 1343 is stacked on the bottom of the bottom shock absorber 1341, and the gasket through-hole 13431 of the gasket 1343 corresponds to the first through-hole 13411 of the bottom shock absorber 1341, wherein the connecting piece 1344 includes a cylindrical 13441 and a ring body 13442 extending from the top of the cylinder 13441 to the surroundings, the ring body 13442 is stacked on the top of the top shock absorber 1342, the cylinder 13441 is inserted into the second through-hole 13421 of the top shock absorber 1342, the first through-hole 13411 of the bottom shock absorber 1341 and the gasket through-hole 13431 of the gasket 1343, in this way, first, the The connecting piece 1344 isolates the screw 15 and the bottom shock absorber 1341 and isolates the screw 15 and the top shock absorber 1342, preventing the bottom shock absorber 1341 and the top shock absorber 1342 from being cut by the thread of the screw 15. Secondly, after the bottom shock absorber 1341 and the top shock absorber 1342 are aged due to long-term use and / or corrosion, the connecting piece 1344 can prevent the bottom shock absorber 1341 and the top shock absorber 1342 from falling off. Thirdly, in the process of the screw 15 being screwed onto the top pad 133, the gasket 1343 and the connecting piece 1344 can prevent the bottom shock absorber 1341 and the top shock absorber 1342 from being over-compressed and causing breakage, thereby ensuring that the bottom shock absorber 1341 and the top shock absorber 1342 have good shock-absorbing effect, thereby ensuring the detection accuracy of the sonar.
[0045] Reference Attachment Figure 1 and Figure 2 In this specific example of the shock absorbing device 10 of the present invention, the number of the shock absorbing support assemblies 13 is three, namely a first shock absorbing support assembly 13a, a second shock absorbing support assembly 13b and a third shock absorbing support assembly 13c. The wire rope shock absorber 132 of the second shock absorbing support assembly 13b and the wire rope shock absorber 132 of the third shock absorbing support assembly 13c are tilted and symmetrically arranged. The symmetry axis of the wire rope shock absorber 132 of the second shock absorbing support assembly 13b and the wire rope shock absorber 132 of the third shock absorbing support assembly 13c is perpendicular to the wire rope shock absorber 132 of the first shock absorbing support assembly 13a and passes through the center of the wire rope shock absorber 132 of the first shock absorbing support assembly 13a. In this way, the three shock absorbing support assemblies 13 cooperate with each other to not only effectively weaken the vibration, but also ensure the detection accuracy of the sonar 20.
[0046] Preferably, refer to the attached Figure 2 , the wire rope shock absorber 133 of the first shock-absorbing support assembly 13a is in a compressed state, and the wire rope shock absorber 132 of the second shock-absorbing support assembly 13b and the wire rope shock absorber 132 of the third shock-absorbing support assembly 13c are both in a natural state. In this way, it can be ensured that the straight line passing through the center of gravity of the wire rope shock absorber 132 of the first shock-absorbing support assembly 13a and perpendicular to the wire rope shock absorber 132, the straight line passing through the center of gravity of the wire rope shock absorber 132 of the second shock-absorbing support assembly 13b and perpendicular to the wire rope shock absorber 132, the straight line passing through the center of gravity of the wire rope shock absorber 132 of the third shock-absorbing support assembly 13c and perpendicular to the wire rope shock absorber 132, and the straight line passing through the center of gravity of the sonar 20 and consistent with the height direction of the sonar 20 intersect at one point, avoiding the "head-down" problem of the sonar 20.
[0047] Reference Attachment Figures 1 to 3 In this specific example of the shock absorbing device 10 of the present invention, the bottom of the hanging rod 14 is adjacent to the first shock absorbing support assembly 13a.
[0048] Attachment Figures 7 to 11 Another specific example of the shock absorbing device 10 of the present invention is shown. Figures 1 to 6 The shock absorbing device 10 shown is different in that Figures 7 to 11 In the particular example of the shock absorbing device 10 shown, the shock absorbing support assembly 13 is devoid of the bottom pad 131 and the support arm 135 . Specifically, the base frame 1321 of the wire rope shock absorber 132 of the shock absorbing support assembly 13 is directly mounted on the base plate 11, for example, the base frame 1321 is directly mounted on the base plate 11 through a group of the screws 15 to mount the bottom of the wire rope shock absorber 132 on the base plate 11, the top frame 1322 of the wire rope shock absorber 132 is directly mounted on the top pad 133, for example, the top frame 1322 is directly mounted on the top pad 133 through a group of the screws 15 to mount the top of the wire rope shock absorber 132 on the top pad 133, and the rubber shock absorber 134 is mounted on the top pad 133 and the top plate 12 to suspend the top plate 12 above the top pad 133. It is understandable that, since the shock-absorbing support assembly 13 does not have the bottom pad 131 and the support arm 135, the distance between the bottom plate 11 and the top plate 12 is smaller than that of the attached Figures 1 to 6 For the shock absorbing device 10 shown in FIG. Figures 7 to 11 The damping device 10 is shown flattened. Figures 7 to 11In the particular example of the shock absorbing device 10 shown, the sonar 20 is located above the top plate 12 .
[0049] Continue to refer to the attached Figures 7 to 11 In this specific example of the shock absorbing device 10 of the utility model, the number of the hanging rods 14 is two, and the bottoms of the two hanging rods 14 are respectively installed at the opposite ends of the bottom plate 11. Therefore, relative to the attached Figures 1 to 6 For the shock absorbing device 10 shown in FIG. Figures 7 to 11 In the specific example of the shock absorbing device 10 shown, the wire rope shock absorbers 132 of all the shock absorbing support assemblies 13 can be in a natural state.
[0050] Reference Attachment Figure 10 , the top plate 12 has a top plate through-hole 121, wherein the top of the bottom shock absorber 1341 is inserted into the top plate through-hole 121 of the top plate 12 from bottom to top, and the bottom of the top shock absorber 1342 is inserted into the top plate through-hole 121 of the top plate 12 from top to bottom, and the threaded end of the screw 15 passes through the second through-hole 13421 of the top shock absorber 1342 and the first through-hole 13411 of the bottom shock absorber 1341 in sequence and is screwed onto the top pad 133, so that the bottom of the rubber shock absorber 134 is installed on the top pad 133, and the middle part of the rubber shock absorber 134 is installed on the top plate through-hole 121 of the top plate 12. It can be understood that the bottom shock absorber 1341 isolates the top pad 133 and the top plate 12 to avoid direct contact between the top pad 133 and the top plate 12, and the bottom shock absorber 1341 isolates the screw 15 and the top plate 12, and the top shock absorber 1342 isolates the screw 15 and the top plate 12, so that the rubber shock absorber 134 can effectively weaken the high frequency in the vibration.
