[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] In order to address the technical problem that the existing shipborne radar anti-vibration device only has a spring at the bottom of the radar mounting base, the shock absorption effect is poor and cannot meet the requirements of buffering and damping the left and right shaking of the radar in the sea environment, and thus cannot ensure the stability of the radar, the present invention proposes a shock-absorbing device and a shipborne radar system, which use the damping generated by the buffering medium and the spring to jointly absorb the shock of the radar, thereby improving the shock-absorbing effect; at the same time, the present invention can ensure that no matter whether the radar generates horizontal or vertical bumps, it can be stably buffered.

[0035] Figure 1 and Figure 2 A schematic diagram of the overall structure of a shockproof device according to the present invention is given. Figure 1 and Figure 2 As shown, the shock-proof device provided by the present invention includes a base 100, a plurality of buffer pipes 200 and a plurality of shock-absorbing modules 300. The base 100 has a placement cavity 101 for placing a radar mounting seat 400 and a buffer cavity for filling a buffer medium. One end of the plurality of buffer pipes 200 is respectively connected to the placement cavity 101, and the other end is arranged in the buffer cavity. Each shock-absorbing module 300 includes a force transmission rod 320 and a first valve 330. One end of the force transmission rod 320 contacts the outer wall of the placement cavity 101, and the other end is arranged in the corresponding buffer pipe 200. The first valve 330 is arranged on the side of the force transmission rod 320 away from the placement cavity 101 and is sealed and slidably connected to the inner wall of the buffer pipe 200. The first valve 330 is opened by the movement of the force transmission rod 320 so that the buffer medium enters the buffer pipe 200 to generate damping.

[0036] When the present invention is in use, when the radar shakes, the radar mounting seat 400 pushes the force transmission rod 320 to move toward the buffer chamber, and the pressure of the buffer medium in the buffer chamber increases, thereby pushing the first valve 330 to open, so that the buffer medium enters the buffer pipe 200 to generate damping. At this time, the shock absorbing module 300 and the generated damping jointly reduce the shock of the radar mounting seat 400, thereby improving the shockproof effect.

[0037] In one embodiment, since the radar will vibrate not only vertically but also horizontally in a marine environment, the anti-vibration device provided by the present invention needs to consider buffering and damping the radar in both the vertical and horizontal directions, so as to ensure the stability of the radar in the harsh marine environment. Therefore, in this embodiment, the buffer cavity formed on the base 100 includes a first cavity 102, a second cavity 103, and a third cavity 104, and the first cavity 102, the second cavity 103, and the third cavity 104 are all filled with a buffer medium; one end of the plurality of buffer pipes 200 is respectively arranged on the four sides and the bottom of the placement cavity 101 in the horizontal direction, and the other end of the plurality of buffer pipes 200 is respectively connected to the first cavity 102, the second cavity 103, and the third cavity 104; one end of the plurality of shock-absorbing modules 300 is respectively abutted against the four sides and the bottom wall of the radar mounting base 400, and the other end thereof is respectively arranged in the plurality of buffer pipes 200.

[0038] In the above technical solution, the shock-absorbing module 300 is disposed around the outer wall and bottom wall of the radar mount 400, that is, the shock-absorbing module 300 is disposed in both the horizontal and vertical directions of the radar mount 400. Thus, when the radar mount 400 experiences horizontal shaking or vertical bouncing, the buffering medium in the first cavity 102, the second cavity 103, and the third cavity 104 can all enter the corresponding buffer pipe 200. With the other end of the shock-absorbing module 300 disposed in the buffer pipe 200, the buffering medium in the buffer pipe 200 can damp the shock-absorbing module 300, thereby achieving buffering and shock reduction for the radar mount 400. Therefore, the shock-absorbing device provided by the present invention can provide shock absorption in both the horizontal and vertical directions, ensuring the stable operation of the radar in marine environments.

[0039] In one embodiment, Figure 3As shown, the base 100 and the radar mounting base 400 are both rectangular. Under this condition, the formation of the first cavity 102, the second cavity 103 and the third cavity 104 is preferably as follows: the base 100 includes a first baffle 110, a second baffle 120, a third baffle 130 and a connecting plate 140, the first baffle 110, the second baffle 120 and the third baffle 130 are also rectangular, and the first baffle 110, the second baffle 120 and the third baffle 130 are distributed in sequence from the center of the base 100 to the outside, and a group of adjacent sides of the first baffle 110 are respectively provided with notches 110, 111 and 111. 1. The two ends of the connecting plate 140 are respectively connected to the notch 111 and the second partition 120, then the space enclosed by the first partition 110 and the connecting plate 140 forms the placement cavity 101, the space enclosed by the first partition 110, part of the second partition 120 and part of the connecting plate 140 forms the first cavity 102, the space enclosed by the second partition 120 and the third partition 130 forms the second cavity 103, and the space enclosed by part of the first partition 110, part of the second partition 120 and part of the connecting plate 140 forms the third cavity 104.

[0041] In one embodiment, the first cavity 102 and the second cavity 103 are both filled with a buffer medium, which is hydraulic oil. Since the third cavity 104 is an independent cavity, it is not connected to the first cavity 102 and the second cavity 103. Therefore, in addition to being filled with hydraulic oil, the third cavity 104 is also filled with expandable and compressible nitrogen or liquid nitrogen on the top of the hydraulic oil. The height of the third cavity 104 should be greater than the heights of the first cavity 102 and the second cavity 103, respectively, to facilitate the storage of the buffer medium.

The contact 310 and the first valve 330 are respectively arranged at the two ends of the force transmission rod 320. The first elastic member 340 is sleeved on the outside of the force transmission rod 320. One end of the first elastic member 340 contacts the contact 310. The contact 310 abuts against the outer wall of the radar mounting seat 400. The side of the force transmission rod 320 on which the first valve 330 is installed is arranged inside the buffer pipe 200, and the outer wall of the first valve 330 is adapted to the inner wall of the buffer pipe 200.

[0044] In one embodiment, the first valve 330 includes a first regulating plate 331, a first baffle 332, a second baffle 333, a second elastic member 334 and a third elastic member 335. The first regulating plate 331 is sleeved on the outside of the force transmission rod 320. The first regulating plate 331 is provided with a first hole 3311 and a second hole 3312. The first baffle 332 and the second elastic member 334 are sequentially sleeved on the outside of the force transmission rod 320 on the side of the first regulating plate 331 close to the contact 310. One end of the second elastic member 334 is fixedly connected to the first baffle 332. The first baffle 332 is provided with a second elastic member 334. Only the first hole 3311 is blocked, that is, a hole corresponding to the second hole 3312 is provided on the first baffle 332, or the outer edge of the first baffle 332 is within the inner edge of the first hole 3311; the second baffle 333 and the third elastic member 335 are sequentially sleeved on the outside of the force transmission rod 320 on the side of the first adjustment plate 331 away from the contact 310, one end of the third elastic member 335 is fixedly connected to the second baffle 333, and the second baffle 333 only blocks the second hole 3312, that is, a hole for circulation corresponding to the first hole 3311 is provided on the second baffle 333.

[0045] In one embodiment, in order to connect the first cavity 102 and the second cavity 103, and to connect the third cavity 104 and the placement cavity 101, the shockproof device also includes a second valve 500, and the second partition plate 120 is away from a group of adjacent edges of the third cavity 104 and the base 100 is located at the bottom edge of the third cavity 104. Through holes are respectively opened, and multiple second valves 500 are respectively arranged in the through holes.

[0046] In one embodiment, Figure 6 As shown, the second valve 500 includes a cylinder 510, a second adjustment plate 520, a third baffle 530, a fourth baffle 540, a fourth elastic member 550 and a fifth elastic member 560.

The fourth baffle 540 and the fifth elastic member 560 are sequentially sleeved on the other side of the second adjustment plate 520. The fourth baffle 540 only blocks the fourth hole 522.

[0047] In one embodiment, the stiffness of the fourth elastic member 550 and the fifth elastic member 560 is greater than the stiffness of the second elastic member 334 and the third elastic member 335 .

[0048] It is understandable that the structure and working principle of the second valve 500 are the same as those of the first valve 330 , so for positions not mentioned in the above description of the second valve 500 , please refer to the description of the first valve 330 of the present invention.

[0049] In one embodiment, Figure 7 As shown, a first groove 410 for contacting the contact 310 is formed on the side surface of the radar mounting base 400 , and a second groove 420 for contacting the contact 310 is formed on the bottom surface of the radar mounting base 400 .

[0050] In one embodiment, in order to support the radar mount 400 , the area of ​​the contact 310 for contacting the second groove 420 is larger than the area of ​​the contact 310 for contacting the first groove 410 .

[0051] The working principle of the shockproof device provided by the present invention is as follows:

[0052] In the initial state, the radar mounting base 400 is located in the center of the placement cavity 101, and the contacts 310 of the five shock-absorbing modules 300 are respectively in contact with the radar mounting base 400 from the four sides and the bottom surface. The other ends of the five shock-absorbing modules 300 are arranged in the corresponding buffer pipes 200, and the first cavity 102, the second cavity 103 and the third cavity 104 are filled with buffer medium. At this time, the volume and pressure of the buffer medium in each cavity are kept balanced, and the five shock-absorbing modules 300 support the radar mounting base 400 in the horizontal and vertical directions respectively.

[0053] When the ship is bumping during operation, for example, the radar mounting seat 400 moves to the left, the shock absorbing module 300 connected thereto will be pushed to move in the direction of the first cavity 102, and the first elastic member 340 of the shock absorbing module 300 will be compressed first. At the same time, since the stiffness of the fourth elastic member 550 and the fifth elastic member 560 in the second valve 500 is greater than the stiffness of the second elastic member 334 and the third elastic member 335 in the first valve 330, then under the hydraulic action of the buffer medium (hydraulic oil) in the first cavity 102, the buffer medium will flow to the first hole 3311, and then push the first baffle 332 to compress the second elastic member 334, so that the first hole 3311 is opened, and the buffer medium (hydraulic oil) flows into the first buffer pipe 210 to generate damping; at the same time, due to the process of movement, the volume of the force transmission rod 320 of the shock absorbing module 300 entering the first buffer pipe 210 gradually increases. Increase, so a part of excess buffer medium will be generated in the first cavity 102, resulting in an increase in the hydraulic pressure in the first cavity 102, and the second valve 500 installed in the through hole will be opened, so that the buffer medium will flow into the second cavity 103, thereby increasing the hydraulic pressure in the second cavity 103, and since one end of the second buffer pipe 220 is directly connected to the second cavity 103, the increase in the hydraulic pressure in the second cavity 103 will push the shock absorbing module 300 installed in the second buffer pipe 220 to move, so that the force transmission rod 320 of this part moves out of the second buffer pipe 220, and then push the contact 310 to always abut against the side wall of the radar mounting seat 400 to reduce the shock of the radar mounting seat 400. At this time, the pressures in the first cavity 102 and the second cavity 103 are balanced, and the damping generated during this movement can better buffer the shaking caused by the bumps of the ship, so that the radar remains stable. It can be understood that the above is an illustration of the working principle of the shockproof device provided by the present invention using the leftward movement of the radar mounting base 400 as an example. The working principle of the rightward, upward and downward movement of the radar mounting base 400 is the same as the above-mentioned leftward movement, and will not be repeated here.

[0054] It should be noted that since the four sides of the radar mounting base 400 are provided with a first groove 410 and the bottom surface is provided with a second groove 420, the contact 310 of the shock-absorbing module 300 can slide in the first groove 410 and the second groove 420, so the radar mounting base 400 can achieve 360° movement in the horizontal direction to cope with shaking impacts generated in any direction; since the first buffer pipe 210 and the second buffer pipe 220 are both liquid and there is no compressible gas, when the radar mounting base 400 moves horizontally in a certain direction, the shock-absorbing module 300 in the other direction will always maintain contact with the radar mounting base 400, and then when the shaking and bumping are reversed, shock absorption and buffering can be performed in time. If the cavity contains compressible gas, the shock-absorbing module 300 in the other direction will not always maintain close contact with the radar mounting base 400.

[0055] When the radar produces vertical bumps, the shock absorbing module 300 installed at the bottom of the radar mounting seat 400 is driven to move upward. The buffer medium in the third cavity 104 enters the third buffer pipe 230 to generate damping to reduce the vertical shock of the radar mounting seat 400. At the same time, due to the change in the volume of the force transmission rod 320 in the third buffer pipe 230, the excess liquid is squeezed into the third cavity 104 through the second valve 500. Since the bottom of the third cavity 104 is placed with liquid and the upper part is stored with compressible gases such as nitrogen, the liquid entering the third cavity 104 is temporarily stored by compressing the compressible gas, and at the same time provides power for the vertical upward movement of the radar. The simultaneous operation of the shock absorbing module 300 and the second valve 500 further generates damping to offset the vertical bumps.

[0056] In a second aspect, the present invention further provides a shipborne radar system, comprising the anti-vibration device provided in the first aspect of the present invention, a radar, and a radar mounting base 400, wherein the radar is mounted on the anti-vibration device via the radar mounting base 400.

[0057] In summary, the anti-vibration device and shipborne radar system provided by the present invention can achieve shock absorption and buffering in the horizontal and vertical directions, so that no matter whether the radar generates horizontal or vertical bumps, they can be buffered smoothly.

[0058] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
