[0028] With reference to the accompanying drawings of the present invention Figures 1 to 8 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, the sonar body 20 is mounted on the shock absorbing mechanism 10, and the shock absorbing mechanism 10 can be mounted on a submersible or a hull. Different from the prior art in which the sonar is rigidly mounted on the hull through the main mounting rod, the sonar of the present invention mounts the sonar body 20 on the submersible or the hull through the shock absorbing mechanism 10. When the submersible or the hull is hit or impacted and vibrates, the shock absorbing mechanism 10 can weaken the vibration, effectively reducing the influence of the vibration on the sonar body 20, thereby ensuring the detection accuracy of the sonar body 20.

[0029] It can be understood that the sonar body 20 includes a transmitting cabin 21, a receiving cabin 22 and a watertight cable 23 installed with each other, the transmitting cabin 21 includes a transmitting transducer for generating and transmitting sound signals, the receiving cabin 22 includes a receiving transducer for receiving the reflected sound signals and processing them, one end of the watertight cable 23 is arranged in the receiving cabin 22 and connected to the circuits of the transmitting cabin 21 and the receiving cabin 22, and the other end is connected to a control unit (the control unit is usually arranged in a submersible or a hull) for realizing power supply, data transmission, etc., so that the sonar body 20 can realize the detection of the underwater environment.

[0030] Reference Figures 1 to 8The shock absorbing mechanism 10 includes a bottom plate 11, a top plate 12 and a group of shock absorbing units 13, the bottom of each shock absorbing unit 13 is respectively installed on the bottom plate 11, and the top of each shock absorbing unit 13 is respectively installed on the top plate 12, so that the shock absorbing mechanism 10 forms a receiving cavity 14 between the bottom plate 11 and the top plate 12. The sonar body 20 is installed on the bottom plate 11, and the sonar body 20 is located in the receiving cavity 14 of the shock absorbing mechanism 10. In other words, the sonar body 20 is located between the bottom plate 11 and the top plate 12 of the shock absorbing mechanism 10. The top plate 12 can be set on a submersible or a hull. When the submersible or the hull vibrates, the vibration will be directly transmitted to the top plate 12, causing the top plate 12 to vibrate. The shock absorbing units 13 cooperate with each other to effectively weaken the vibration and prevent the vibration from being transmitted toward the bottom plate 11, thereby reducing the impact of the vibration on the sonar body 20 installed on the bottom plate 11, so as to ensure the detection accuracy of the sonar body 20.

[0031] In the attached Figures 1 to 8 In this specific example of the sonar of the present invention shown, the sonar body 20 is mounted on the bottom plate 11 by at least one screw 100. Specifically, the bottom plate 11 has a series of bottom plate screw holes 111, and the sonar body 20 has at least one body threaded hole 24. After the sonar body 20 is placed above the bottom plate 11, the position of the body threaded hole 24 of the sonar body 20 corresponds to the position of the bottom plate screw hole 111 in the middle of the bottom plate 11. The threaded end of the screw 100 extends to the body threaded hole 24 of the sonar body 20 after passing through the bottom plate screw hole 111 of the bottom plate 11, and the threaded end of the screw 100 is screwed to the sonar body 20, so that the sonar body 20 is mounted on the bottom plate 11 by the screw 100. Preferably, the two screws 100 are used to mount the sonar body 20 on the bottom plate 11 to prevent the sonar body 20 from rotating relative to the bottom plate 11 , so that the sonar body 20 is reliably mounted on the bottom plate 11 .

[0032] In the attached Figures 1 to 8In this specific example of the sonar of the present invention shown, the shock absorbing mechanism 10 includes a lifting tube 15, the lifting tube 15 has a cable channel 151, the top plate 12 has a top plate channel 121, the top plate channel 121 is connected to the accommodating chamber 14 of the shock absorbing mechanism 10, the bottom of the lifting tube 15 is installed on the top plate 12, the cable channel 151 of the lifting tube 15 is connected to the top plate channel 121 of the top plate 12, wherein the watertight cable 23 of the sonar body 20 extends from the accommodating chamber 14 of the shock absorbing mechanism 10 to the cable channel 151 of the lifting tube 15 through the top plate channel 121 of the top plate 12, wherein the top of the lifting tube 15 is installed on the submersible or the hull, so that the top plate 12 is set on the submersible or the hull through the lifting tube 15. Optionally, in other specific examples of the sonar of the present invention, the top plate 12 may also be directly mounted on a submersible or a hull, so as to set the top plate 12 on the submersible or the hull.

[0033] In order to facilitate the installation of the bottom of the lifting tube 15 on the top plate 12 and the installation of the top of the lifting tube 15 on the submersible or the hull, the lifting tube 15 has a bottom flange 152 and a top flange 153. The bottom flange 152 of the lifting tube 15 is locked to the top plate 12 through a group of screws 100 to install the bottom of the lifting tube 15 on the top plate 12, and the top flange 153 is locked to the submersible or the hull through a group of screws 100 to install the top of the lifting tube 15 on the submersible or the hull.

[0034] In the attached Figures 1 to 8 In the specific example of the sonar of the present invention shown, the number of the shock absorbing units 13 of the shock absorbing mechanism 10 is three, one of the three shock absorbing units 13 is arranged at the rear to form a rear shock absorbing unit 1301, and the other two shock absorbing units 13 are arranged at both sides to form a side shock absorbing unit 1302 respectively, and the two side shock absorbing units 1302 are symmetrical to each other and are arranged obliquely, and a straight line L1 passing through the center of gravity of the rear shock absorbing unit 1301 and perpendicular to the rear shock absorbing unit 1301, passing through one of the The straight line L2 at the center of gravity of the side shock absorbing unit 1302 and perpendicular to the side shock absorbing unit 1302 and the straight line L3 passing through the center of gravity of another side shock absorbing unit 1302 and perpendicular to the side shock absorbing unit 1302 intersect at one point, and a straight line passing through the center of gravity of the sonar body 20 and along the height direction of the sonar body 20 passes through the intersection of the straight line L1, the straight line L2 and the straight line L3. In this way, a group of the shock absorbing units 13 can ensure the balanced force of the sonar body 20 while ensuring the effect of weakening the vibration.

[0035] Specifically, each of the shock absorbing units 13 includes an assembly frame 131, at least one rubber shock absorber 132, a bottom adapter plate 133, a wire rope shock absorber 134, and a top adapter plate 135, wherein the bottom of the assembly frame 131 is mounted on the bottom plate 11, and the bottom adapter plate 133 is mounted on the top of the assembly frame 131 through the rubber shock absorber 132, that is, the rubber shock absorber 132 isolates the assembly frame 131 and the bottom adapter plate 133, and the bottom of the wire rope shock absorber 134 is mounted on the bottom The adapter plate 133, the top of the wire rope shock absorber 134 is installed on the bottom of the top adapter plate 135, that is, the wire rope shock absorber 134 isolates the bottom adapter plate 133 and the top adapter plate 135, and the top of the top adapter plate 135 is installed on the top plate 12. In this way, the bottom of the shock absorbing unit 13 is installed on the bottom plate 11, and the top of the shock absorbing unit 13 is installed on the top plate 12, so that the shock absorbing mechanism 10 forms the accommodating cavity 14 between the bottom plate 11 and the top plate 12.

[0036] In the attached Figures 1 to 8 In this specific example of the sonar of the present invention, the rubber shock absorber 132 is not directly mounted on the wire rope shock absorber 134, but a bottom adapter plate 133 is provided between the rubber shock absorber 132 and the wire rope shock absorber 134, and the top of the wire rope shock absorber 134 is not directly mounted on the top plate 12, but a top adapter plate 135 is provided between the wire rope shock absorber 134 and the top plate 12. In this way, on the one hand, It is beneficial to improve the effect of the wire rope shock absorber 134 in weakening the low-frequency part of the vibration transmitted to the top plate 12 and the effect of the rubber shock absorber 132 in weakening the high-frequency part of the vibration transmitted to the top plate 12, so as to improve the shock absorbing effect of the shock absorbing mechanism 10. On the other hand, the bottom adapter plate 133 and the top adapter plate 135 can increase the distance between the bottom plate 11 and the top plate 12, so that the distance between the bottom plate 11 and the top plate 12 meets the height requirement of the sonar body 20.

[0037] It is understandable that the sonar bodies 20 of different specifications have different height dimensions, resulting in different requirements for the distance between the bottom plate 11 and the top plate 12 for the sonar bodies 20 of different specifications. By respectively arranging the bottom adapter plate 133 and the top adapter plate 135 at the bottom and the top of the wire rope shock absorber 134, when the rubber shock absorber 132 and the wire rope shock absorber 134 are used as standard parts, it is only necessary to replace the bottom adapter plate 133 and the top adapter plate 135 with different thickness dimensions according to the height dimension of the sonar body 20. It is understandable that in order to meet the height requirements of the sonar body 20, the shock absorbing mechanism 10 can also replace the assembly frame 131 with different height dimensions.

[0038] Reference Figures 4 to 7 The bottom of the assembly frame 131 has at least one frame threaded hole 1311, and the position of the frame threaded hole 1311 of the assembly frame 131 corresponds to the position of the bottom plate screw hole 111 at the edge of the bottom plate 11. The threaded end of the screw 100 extends to the frame threaded hole 1311 of the assembly frame 131 after passing through the bottom plate screw hole 111 of the bottom plate 11, and the threaded end of the screw 100 is screwed to the assembly frame 131 to install the bottom of the assembly frame 131 on the bottom plate 11. Preferably, the bottom of the assembly frame 131 has four frame body threaded holes 1311, and the threaded ends of the four screws 100 extend to the four frame body threaded holes 1311 of the assembly frame 131 after respectively passing through the four bottom plate screw holes 111 located at the edge of the bottom plate 11 and are screwed to the assembly frame 131, so that the assembly frame 131 is reliably installed on the bottom plate 11. More preferably, the four frame body threaded holes 1311 at the bottom of the assembly frame 131 are in two rows.

[0039] Continue to refer to the attached Figures 4 to 7, the top of the assembly frame 131 has a locking arm 1312 and two frame through holes 1313 on opposite sides, each of the locking arms 1312 of the assembly frame 131 has a frame through hole 1313, the number of the rubber shock absorbers 132 is two, the middle of each rubber shock absorber 132 is respectively installed on each frame through hole 1313 of the assembly frame 131, and the opposite ends of the rubber shock absorber 132 protrude from the bottom and top of the assembly frame 131, wherein the rubber shock absorber 132 has a shock absorber through hole 1321, the bottom adapter plate 133 has two first adapter plate threaded holes 1331, the position of each of the first adapter plate threaded holes 1331 of the bottom adapter plate 133 corresponds to the position of the shock absorber through hole 1321 of each rubber shock absorber 132, and one of the screw rods 10 The threaded end of one of the screw rods 100 extends to one of the first adapter plate threaded holes 1331 of the bottom adapter plate 133 after passing through the shock absorber through hole 1321 of one of the rubber shock absorbers 132, and the threaded end of the screw rod 100 is screwed onto the bottom adapter plate 133, and the threaded end of another of the screw rods 100 extends to another of the first adapter plate threaded holes 1331 of the bottom adapter plate 133 after passing through the shock absorber through hole 1321 of another of the rubber shock absorbers 132, and the threaded end of the screw rod 100 is screwed onto the bottom adapter plate 133, in this way, the bottom adapter plate 133 is installed on the top of the assembly frame 131 through the rubber shock absorber 132, and the rubber shock absorber 132 isolates the screw rod 100 and the assembly frame 131 to effectively weaken the high-frequency part of the vibration.

[0040] Continue to refer to the attached Figures 4 to 7The rubber shock absorber 132 includes a lower shock absorbing part 1322 and an upper shock absorbing part 1323. The lower shock absorbing part 1322 includes a lower shock absorbing tube 13221 and a lower insertion tube 13222 extending upward from the lower shock absorbing tube 13221. The outer diameter of the lower insertion tube 13222 is smaller than the outer diameter of the lower shock absorbing tube 13221, and the outer diameter of the lower insertion tube 13222 is consistent with the inner diameter of the frame through hole 1313 of the assembly frame 131. Therefore, it can be understood that the outer diameter of the lower shock absorbing tube 13221 is larger than the inner diameter of the frame through hole 1313 of the assembly frame 131. The upper shock absorbing part 1323 includes an upper shock absorbing tube 13231 and an upper insertion tube 13232 extending downward from the upper shock absorbing tube 13231. The outer diameter of the upper insertion tube 13232 is smaller than the outer diameter of the upper shock absorbing tube 13231, and the outer diameter of the upper insertion tube 13232 is consistent with the inner diameter of the frame through hole 1313 of the assembly frame 131. Therefore, it can be understood that the outer diameter of the upper shock absorbing tube 13231 is larger than the inner diameter of the frame through hole 1313 of the assembly frame 131. The lower insertion tube 13222 of the lower shock absorbing part 1322 is inserted into the frame through hole 1313 of the assembly frame 131 from bottom to top, the lower shock absorbing tube 13221 of the lower shock absorbing part 1322 is superimposed on the lower side of the locking arm 1312 of the assembly frame 131, the upper insertion tube 13232 of the upper shock absorbing part 1323 is inserted into the frame through hole 1313 of the assembly frame 131 from top to bottom, the upper shock absorbing tube 13231 of the upper shock absorbing part 1323 is superimposed on the upper side of the locking arm 1312 of the assembly frame 131, so that the middle part of the rubber shock absorber 132 is installed in the frame through hole 1313 of the assembly frame 131, and the opposite ends of the rubber shock absorber 132 protrude from the bottom and the top of the assembly frame 131 respectively. When the opposite two ends of the bottom adapter plate 133 are respectively supported by the upper shock absorbing tubes 13231 of the upper shock absorbing parts 1323 of the two rubber shock absorbers 132, and the position of each of the first adapter plate threaded holes 1331 of the bottom adapter plate 133 corresponds to the position of the shock absorber through-holes 1321 of each rubber shock absorber 132, the threaded end of the screw rod 100 extends to the first adapter plate threaded hole 1331 of the bottom adapter plate 133 after passing through the shock absorber through-holes 1321 of the rubber shock absorber 132, and the threaded end of the screw rod 100 is screwed to the bottom adapter plate 133, so that the bottom adapter plate 133 is installed on the top of the assembly frame 131 through the rubber shock absorber 132.

[0041] Reference Figure 5The lower shock absorbing part 1322 isolates the screw 100 and the locking arm 1312 of the assembly frame 131, and the upper shock absorbing part 1323 not only isolates the screw 100 and the locking arm 1312 of the assembly frame 131, but also isolates the bottom adapter plate 133 and the locking arm 1312 of the assembly frame 131. In this way, the rubber shock absorber 132 can effectively weaken the high-frequency part of the vibration, and reduce the influence of the high-frequency part of the vibration on the bottom plate 11 and the sonar body 20 installed on the bottom plate 11.

[0042] Continue to refer to the attached Figures 4 to 7The rubber shock absorber 132 further includes a metal connector 1324 and a metal gasket 1325, the connector 1324 includes a connecting tube 13241 and a connecting ring 13242 extending outward from the bottom of the connecting tube 13241, that is, the outer diameter of the connecting ring 13242 is larger than the outer diameter of the connecting tube 13241, wherein the outer diameter of the connecting tube 13241 is consistent with the inner diameter of the shock absorber through hole 1321 of the rubber shock absorber 132, the metal gasket 1325 has a gasket through hole 13251, the metal gasket 1325 is stacked on the upper shock absorber tube 13231 of the upper shock absorber part 1323, and the gasket through hole 13251 of the metal gasket 1325 corresponds to the hollow part of the upper shock absorber part 1323. The top of the connecting tube 13241 of the connecting member 1324 passes through the hollow part of the lower shock absorbing part 1322 and the hollow part of the upper shock absorbing part 1323 in sequence, so that the top of the connecting tube 13241 passes through the shock absorber through hole 1321 of the rubber shock absorber 132, and the top of the connecting tube 13241 further passes through the gasket through hole 13251 of the metal gasket 1325. The lower shock absorbing cylinder 13221 is stacked on the lower shock absorbing part 1322, and the threaded end of the screw rod 100 extends to the first adapter plate threaded hole 1331 of the bottom adapter plate 133 after passing through the connecting cylinder 13241 and the gasket through hole 13251 of the metal gasket 1325, and the threaded end of the screw rod 100 is screwed to the bottom adapter plate 133. In this way, in the first aspect, even if the lower shock absorbing part 1322 and the upper After the lower shock absorbing part 1323 ages, the connecting piece 1324 can still ensure that the lower shock absorbing part 1322 and the upper shock absorbing part 1323 will not fall off. On the other hand, the connecting piece 1324 can isolate the lower shock absorbing part 1322 from the screw 100 and isolate the upper shock absorbing part 1323 from the screw 100, so that the lower shock absorbing part 1322 and the upper shock absorbing part 1323 made of rubber material will not be affected by the threaded end of the screw 100. The thread cutting is carried out to protect the lower shock absorbing part 1322 and the upper shock absorbing part 1323. On the third aspect, in the process of screwing the screw 100 to the bottom adapter plate 133, the connecting piece 1324 and the metal gasket 1325 can prevent the lower shock absorbing part 1322 and the upper shock absorbing part 1323 from being excessively compressed and causing breakage, thereby ensuring that the lower shock absorbing part 1322 and the upper shock absorbing part 1323 have good shock absorbing effect.

[0043] That is to say, the connecting piece 1324 and the metal gasket 1325 cooperate with each other, which can not only prevent the lower shock absorbing part 1322 and the upper shock absorbing part 1323 from being over-compressed, but also control the compression amount of the lower shock absorbing part 1322 and the upper shock absorbing part 1323, thereby ensuring that the lower shock absorbing part 1322 and the upper shock absorbing part 1323 have good shock absorbing effect.

[0044] Reference Figures 4 to 7 The wire rope shock absorber 134 includes a bottom extension arm 1341, a top extension arm 1342 and a wire rope spiral 1343. The bottom extension arm 1341 has a row of bottom arm body through holes 13411, and the top extension arm 1342 has a row of top arm body through holes 13421. The bottom extension arm 1341 and the top extension arm 1342 are symmetrically and spaced apart from each other. The position of the hole 13411 corresponds one to one with the position of each of the top arm body through-holes 13421 of the top extension arm 1342, and the wire rope spiral 1343 crosses through each of the bottom arm body through-holes 13411 of the bottom extension arm 1341 and each of the top arm body through-holes 13421 of the top extension arm 1342 in sequence, so that the bottom extension arm 1341 and the top extension arm 1342 are connected by the wire rope spiral 1343. Since the wire rope spiral 1343 extends spirally between the bottom extension arm 1341 and the top extension arm 1342, the wire rope spiral 1343 is elastic. After the bottom extension arm 1341 and the top extension arm 1342 are pressed and moved closer to each other, the wire rope spiral 1343 is deformed and accumulates elastic potential energy. After the pressure applied to the bottom extension arm 1341 and the top extension arm 1342 is removed, the wire rope spiral 1343 returns to its original state and the bottom extension arm 1341 and the top extension arm 1342 are reset.

In this way, the rear shock absorbing unit 1301 and the two side shock absorbing units 1302 can avoid the "nodding" and tilting problems of the sonar body 20, so that the straight line L1 passing through the center of gravity of the rear shock absorbing unit 1301 and perpendicular to the rear shock absorbing unit 1301, the straight line L2 passing through the center of gravity of one side shock absorbing unit 1302 and perpendicular to the side shock absorbing unit 1302, the straight line L3 passing through the center of gravity of another side shock absorbing unit 1302 and perpendicular to the side shock absorbing unit 1302, and the straight line passing through the center of gravity of the sonar body 20 and along the height direction of the sonar body 20 intersect at one point.

Specifically, the top plate 12 has at least one top plate screw hole 122, and the top adapter plate 135 has at least one second adapter plate threaded hole 1352. The position of the top plate screw hole 122 of the top plate 12 corresponds to the position of the second adapter plate threaded hole 1352 of the top adapter plate 135. The threaded end of the screw 100 extends to the second adapter plate threaded hole 1352 of the top adapter plate 135 after passing through the top plate screw hole 122 of the top plate 12, and the threaded end of the screw 100 is screwed to the top adapter plate 135, so that the top adapter plate 135 is mounted on the top plate 12 through the screw 100.

[0049] Preferably, the top adapter plate 135 is installed on the top plate 12 through two rows of screw rods 100, so as to facilitate the uniform force of the wire rope shock absorber 134 and ensure the shock absorption effect of the shock absorption unit 13.
