It is used for determining the ship's position, piloting, and collision prevention, providing necessary navigation guidance for mariners in poor visibility, and playing an important role in navigation. Due to the changeable marine climate, in the case of encountering storms or other bad weather, the hull bumps, which can easily damage the radar, cause the radar to malfunction, and lead to serious problems such as loss of course. Therefore, it is very necessary to provide shock absorption for the radar to ensure its stability. However, the existing shipborne radar shock-proof devices are only springs installed at the bottom of the radar pedestal. Although they have a certain shock-absorbing effect on the radar, the effect is not good, especially in the case of bad weather at sea, the shock-absorbing effect is even worse, and the stability of the radar cannot be guaranteed.

One end of the force transmission rod contacts the outer wall of the placement cavity, and the other end is arranged in the corresponding buffer pipe. The first valve is arranged on the side of the force transmission rod away from the placement cavity and is in sealed sliding connection with the inner wall of the buffer pipe. The first valve is opened by the movement of the force transmission rod so that the buffer medium enters the buffer pipe to generate damping.

[0005] In some embodiments, each shock-absorbing module further includes a contact head and a first elastic member. One end of the contact head is fixed to the force transmission rod, and the other end contacts the placement cavity.

The first baffle only blocks the first hole. The second baffle and the third elastic member are sequentially sleeved on the outside of the force transmission rod on the side of the first adjusting plate away from the contact head. The second baffle is provided with a third hole corresponding to the first hole.

[0007] In some embodiments, the buffer cavity includes a first cavity, a second cavity, and a third cavity. The first cavity and the second cavity are sequentially arranged outside the placement cavity. The third cavity is arranged on one side outside the first cavity and inside the second cavity. The first cavity, the second cavity, and the third cavity are respectively communicated with the buffer pipeline.

[0008] In some embodiments, the first cavity and the second cavity are communicated, and the third cavity is not communicated with either the first cavity or the second cavity.

[0009] In some embodiments, the height of the third cavity is greater than the heights of the first cavity and the second cavity respectively.

[0010] In some embodiments, a second valve is further included.

Therefore, the present invention can simultaneously shock-absorb and buffer the radar mounting base through the damping generated by the shock-absorbing module and the buffer medium, improving the shock-proof effect, thereby ensuring that the radar can remain stable even when used in a marine environment condition, which is beneficial for the radar to play its role.

Detailed implementation manners

[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, 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 used to limit the present invention.

[0018] Aiming at the technical problem that the existing shipborne radar shockproof device only sets springs at the bottom of the radar installation base, and the shock absorption effect is poor and cannot meet the buffering and shock absorption of 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 shockproof device and a shipborne radar system, which jointly shock-absorb the radar through the damping generated by the buffer medium and the spring, improving the shockproof effect; at the same time, the present invention can make the radar buffer smoothly regardless of the bumps in the horizontal or vertical directions.

[0019] Figure 1 and Figure 2 FIGS. and show the overall structural schematic diagram of a shockproof device involved in the present invention. As Figure 1 and Figure 2 shown, the shockproof device provided by the present invention includes a base 100, a plurality of buffer pipes 200 and a plurality of shock absorption 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 ends of the plurality of buffer pipes 200 are respectively connected to the placement cavity 101, and the other ends are arranged in the buffer cavity. Each shock absorption 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 hermetically 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.

[0020] When the present invention is in use, when the radar shakes, the radar mounting seat 400 pushes the force transmission rod 320 to move towards the buffer cavity, then the pressure of the buffer medium in the buffer cavity increases, and further pushes the first valve 330 to open, so that the buffer medium enters the buffer pipe 200 to generate damping. At this time, the shock absorption module 300 and the generated damping jointly shock-absorb the radar mounting seat 400. Therefore, the shockproof effect can be improved.

[0021] In one embodiment, since in a marine environment, the radar will not only vibrate up and down but also sway horizontally, the shock-absorbing device provided by the present invention needs to consider buffering and damping in both the vertical and horizontal directions of the radar, 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 ends of a plurality of the buffer pipes 200 are respectively arranged around the horizontal direction and at the bottom of the placement cavity 101, and the other ends of the plurality of the buffer pipes 200 are respectively connected to the first cavity 102, the second cavity 103 and the third cavity 104; one ends of a plurality of the shock-absorbing modules 300 are respectively abutted against the outer walls around and the bottom wall of the radar mounting seat 400, and the other ends of the plurality of the shock-absorbing modules 300 are respectively arranged in a plurality of the buffer pipes 200.

[0022] In the above technical solution, the shock-absorbing modules 300 are arranged around the outer walls around and the bottom wall of the radar mounting seat 400, that is, the shock-absorbing modules 300 are arranged in both the horizontal and vertical directions of the radar mounting seat 400. Thus, when the radar mounting seat 400 sways horizontally or jumps vertically, the buffer medium in the first cavity 102, the second cavity 103 and the third cavity 104 can enter the corresponding buffer pipes 200. And the other ends of the shock-absorbing modules 300 are arranged in the buffer pipes 200, then the buffer medium in the buffer pipes 200 can generate damping on the shock-absorbing modules 300, thereby realizing buffering and damping for the radar mounting seat 400. Therefore, the shock-absorbing device provided by the present invention can provide shock absorption in both the horizontal and vertical directions, ensuring the use stability of the radar under marine environmental conditions.

[0023] In one embodiment, such as Figure 3As shown, both the base 100 and the radar mounting base 400 are rectangular. Under this condition, the preferred formation method of the first cavity 102, the second cavity 103, and the third cavity 104 is as follows: The base 100 includes a first partition 110, a second partition 120, a third partition 130, and a connecting plate 140. The first partition 110, the second partition 120, and the third partition 130 are also rectangular, and the first partition 110, the second partition 120, and the third partition 130 are sequentially distributed outward from the center of the base 100. Notches 111 are respectively formed on a set of adjacent sides of the first partition 110. The two ends of the connecting plate 140 are respectively connected to the notches 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, a part of the second partition 120, and a 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. The space enclosed by a part of the first partition 110, a part of the second partition 120, and a part of the connecting plate 140 forms the third cavity 104.

[0024] In one embodiment, to ensure the stability of the radar mounting base 400 when shaking in the horizontal direction, the first cavity 102 and the second cavity 103 are communicated; and to avoid unnecessary movement, the third cavity 104 is not communicated with either the first cavity 102 or the second cavity 103.

[0025] In one embodiment, the first cavity 102 and the second cavity 103 are both filled with a buffer medium. The buffer medium is hydraulic oil. Since the third cavity 104 is an independent cavity and is not communicated with the first cavity 102 and the second cavity 103, in addition to being filled with hydraulic oil, nitrogen or liquid nitrogen that can be expanded and compressed is filled above the hydraulic oil in the third cavity 104. Then, the height of the third cavity 104 is respectively greater than the heights of the first cavity 102 and the second cavity 103 to facilitate containing the buffer medium.

[0026] In one embodiment, the buffer pipeline 200 includes a first buffer pipeline 210, a second buffer pipeline 220, and a third buffer pipeline 230. One end of two of the first buffer pipelines 210 is disposed on the first partition 110, and the other end thereof is disposed in the first cavity 102. One end of two of the second buffer pipelines 220 is disposed on the second partition 120, and the other end thereof is disposed in the placement cavity 101. One end of the third buffer pipeline 230 is disposed in the third cavity 104, and the other end thereof is disposed at the bottom of the placement cavity 101. The other ends of the shock absorption module 300 are respectively disposed in the first buffer pipeline 210, the second buffer pipeline 220, and the third buffer pipeline 230.

[0027] In one embodiment, as Figure 4 and Figure 5 shown, the shock absorption module 300 includes a contact head 310, a force transmission rod 320, a first valve 330, and a first elastic member 340. The contact head 310 and the first valve 330 are respectively disposed at two ends of the force transmission rod 320. The first elastic member 340 is sleeved outside the force transmission rod 320. One end of the first elastic member 340 contacts the contact head 310. The contact head 310 abuts against the outer wall of the radar mounting base 400. The side of the force transmission rod 320 where the first valve 330 is installed is disposed inside the buffer pipeline 200, and the outer wall of the first valve 330 is adapted to the inner wall of the buffer pipeline 200.

[0028] In one embodiment, the first valve 330 includes a first adjusting plate 331, a first baffle 332, a second baffle 333, a second elastic member 334, and a third elastic member 335. The first adjusting plate 331 is sleeved outside the force transmission rod 320. The first adjusting 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 outside the force transmission rod 320 on the side of the first adjusting plate 331 close to the contact head 310. One end of the second elastic member 334 is fixedly connected to the first baffle 332. The first baffle 332 only blocks the first hole 3311, that is, the first baffle 332 is provided with a hole corresponding to the second hole 3312 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 outside the force transmission rod 320 on the side of the first adjusting plate 331 away from the contact head 310. One end of the third elastic member 335 is fixedly connected to the second baffle 333. The second baffle 333 only blocks the second hole 3312, that is, the second baffle 333 is provided with a hole corresponding to the first hole 3311 for circulation.

[0029] 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 further includes a second valve 500. Through holes are respectively formed in a set of adjacent sides of the second partition 120 away from the third cavity 104 and the bottom side of the base 100 located in the third cavity 104, and a plurality of the second valves 500 are respectively arranged in the through holes.

[0030] In one embodiment, as Figure 6 shown, the second valve 500 includes a cylinder 510, a second adjusting plate 520, a third baffle 530, a fourth baffle 540, a fourth elastic member 550 and a fifth elastic member 560. The second adjusting plate 520 is sleeved outside the cylinder 510. The second adjusting plate 520 is provided with a third hole 521 and a fourth hole 522. The third baffle 530 and the fourth elastic member 550 are sequentially sleeved on one side of the second adjusting plate 520, and the third baffle 530 only blocks the third hole 521. The fourth baffle 540 and the fifth elastic member 560 are sequentially sleeved on the other side of the second adjusting plate 520, and the fourth baffle 540 only blocks the fourth hole 522.

[0031] 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.

[0032] It can be understood that the structure and working principle of the second valve 500 are the same as those of the first valve 330. Therefore, for the positions not mentioned in the above description of the second valve 500, please refer to the description of the first valve 330 in the present invention.

[0033] In one embodiment, as Figure 7 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.

[0034] In one embodiment, in order to support the radar mounting base 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.

[0035] The working principle of the shockproof device provided by the present invention is as follows: In the initial state, the radar mounting seat 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 seat 400 from the four sides and the bottom, and the other ends of the five shock-absorbing modules 300 are arranged in the corresponding buffer pipes 200. 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 seat 400 in the horizontal and vertical directions respectively.

[0036] When the ship is bumpy during operation, for example, the radar mounting seat 400 moves to the left, which will push the shock absorbing module 300 connected thereto 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, since during the movement, the force transmission rod 320 of the shock absorbing module 300 enters the first buffer pipe 210 and the volume 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. 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 is moved 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 explanation of the working principle of the shockproof device provided by the present invention by taking the radar mounting base 400 moving to the left as an example. The working principle of the radar mounting base 400 moving to the right, upward and downward is the same as the working principle of the above-mentioned leftward movement, and will not be repeated here.

[0037] It should be noted that since the first grooves 410 are provided on all four side surfaces of the radar mounting base 400 and the second groove 420 is provided on its bottom surface, the contact heads 310 of the shock absorption module 300 can slide in the first grooves 410 and the second groove 420. Therefore, the radar mounting base 400 can move 360° in the horizontal direction to cope with the shaking impact generated in any direction. Since both the first buffer pipe 210 and the second buffer pipe 220 are filled with liquid and there is no compressible gas, when the radar mounting base 400 moves horizontally in a certain direction, the shock absorption modules 300 in the other direction will always be in contact with the radar mounting base 400. Thus, when the shaking and bumping reverse, shock absorption and buffering can be carried out in a timely manner. If there is compressible gas in the cavity, the shock absorption modules 300 in the other direction cannot always be in close contact with the radar mounting base 400.

[0038] When the radar generates bumps in the vertical direction, similarly, the shock absorption module 300 installed at the bottom of the radar mounting base 400 is driven to move upward. Then the buffer medium in the third cavity 104 enters the third buffer pipe 230 to generate damping for shock absorption in the vertical direction of the radar mounting base 400. At the same time, due to the change in the volume of the 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 filled with liquid and the upper part stores compressible gas such as nitrogen, the liquid entering the third cavity 104 is temporarily stored by compressing the compressible gas and provides power for the radar to move vertically upward at the same time. The simultaneous operation of the shock absorption module 300 and the second valve 500 further generates damping to offset the bumps in the vertical direction.

[0039] In a second aspect, the present invention further provides a shipborne radar system, including the shockproof device provided in the first aspect of the present invention, a radar, and the radar mounting base 400. The radar is mounted on the shockproof device through the radar mounting base 400.

[0040] In summary, the shockproof device and the shipborne radar system provided by the present invention can achieve shock absorption and buffering in both the horizontal and vertical directions, so that no matter whether the radar generates bumps in the horizontal or vertical direction, it can be smoothly buffered.

[0041] The specific embodiments of the present invention described above do not constitute a limitation to the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
