Description

Technical Field

[0001] This utility model relates to the technical field of radar, and in particular to a protective device for radar antennas. Background Technology

[0002] Marine radar antennas are often installed on islands and mountains. In the environment of super typhoons, radar antennas are subjected to the combined effects of mountain winds and horizontal winds. The stress situation is far more complex than that in laboratory environments. In super typhoons such as "Mangkhut" that were predicted to be at level 16 to 17, there have been many cases of radar antennas being damaged due to high-speed rotation and eventually detaching from the gearbox, causing huge losses.

[0003] Currently, most of the hundreds of maritime radar stations already built in China adopt an infrastructure design without windshields. The radar antennas on these stations need to be able to dissipate energy and slow down in strong winds to prevent them from derailing due to excessive rotation, which could cause significant losses and safety accidents. Utility Model Content

[0004] The present invention aims to at least solve one of the aforementioned technical problems existing in the prior art. Therefore, the purpose of this invention is to provide a protective device for radar antennas, improving the protection capability and operational reliability of radar stations without windshields under extreme weather conditions.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A protective device for a radar antenna, disposed between a radar rotating component and a radar driving component, comprising: A brake support base is used to support the radar rotating component, the radar driving component, and the protective device, wherein the radar driving component is mounted on the brake support base. The braking main structure includes a first braking mechanism for limiting the rotation of the radar rotating component and a second braking mechanism for rotating synchronously with the radar rotating component. The first braking mechanism is movably connected to the braking support seat, and the second braking mechanism is fixedly connected to the radar rotating component. A braking power structure is disposed on the brake support seat and is movably connected to the first braking mechanism; When the radar rotating component enters the braking state, the braking power structure drives the first braking mechanism to press against the second braking mechanism to perform braking; when the radar rotating component enters the rotation state, the braking power structure drives the first braking mechanism to disengage from the second braking mechanism to release the braking state.

[0006] The beneficial effects of this utility model are as follows: This application adopts a structural design of friction braking and mechanical limiting. The first braking mechanism is movably connected to the braking support seat, and the second braking mechanism is fixedly connected to the radar rotating part for synchronous rotation. By connecting the braking power structure set on the braking support seat with the first braking mechanism, the braking power structure can drive the first braking mechanism to press against or disengage from the second braking mechanism to switch the braking state and rotation state of the radar rotating part. Moreover, in strong wind environments, the braking power structure actively drives the first braking mechanism to press against the second braking mechanism that rotates synchronously with the radar rotating part for friction braking, so that the radar antenna can effectively dissipate energy and reduce speed. At the same time, the downward pressure generated when the first braking mechanism brakes can offset the upward force generated by the rotation of the radar rotating part, thereby reducing the risk of the radar rotating part derailing in super typhoons and improving the protection capability and operational reliability of the radar station without a windshield in extreme weather conditions.

[0007] As described above, a protective device for a radar antenna includes a braking power structure comprising a first driving structure and a second driving structure.

The second drive structure also includes a second drive structure body and a second extension for driving the first braking mechanism to move; one end of the second extension is connected to the second drive structure body and the other end is connected to the first braking mechanism.

[0009] As described above, the protection device for a radar antenna further includes a first drive motor and a second drive motor for maintaining a power-off braking state; the first drive motor and the second drive motor are respectively mounted on the first drive structure body and the second drive structure body, and are rotatably connected to the first extension and the second extension respectively.

[0023] like Figures 1-14 As shown, an embodiment of this utility model provides a protective device for a radar antenna, disposed on the outside of the radar rotating component 11 and the radar driving component 12, comprising: The braking support 2, braking main structure 3, and braking power structure are used to support the radar rotating component 11, the radar driving component 12, and the protection device. The braking main structure 3 includes a first braking mechanism 31 for limiting the rotation of the radar rotating component 11 and a second braking mechanism 32 for rotating synchronously with the radar rotating component 11. The first braking mechanism 31 is movably connected to the braking support 2, and the second braking mechanism 32 is fixedly connected to the radar rotating component 11. The braking power structure is connected to the side of the braking support 2 facing the radar rotating component 11 and is movably connected to the first braking mechanism 31. When the radar rotating component 11 enters the braking state, the braking power structure drives the first braking mechanism 31 to press against the second braking mechanism 32 to perform braking. When the radar rotating component 11 enters the rotation state, the braking power structure drives the first braking mechanism 31 to disengage from the second braking mechanism 32 to release the braking state.

[0024] In this embodiment of the utility model, the radar rotating component 11 is rotatably connected to the radar driving component 12, and the brake support seat 2 serves as the base of the entire protection device, providing a stable installation foundation; the first brake mechanism 31 of the brake main structure 3 is an active structure, and the second brake mechanism 32 is a driven structure. The cooperation between the active and driven structures forms an efficient brake friction pair, which is beneficial for braking and decelerating the radar rotating component 11; the setting of the brake power structure realizes active and precise control of the braking and de-braking states of the radar antenna, ensuring the safe locking of the radar antenna in non-working states or emergency situations, as well as smooth rotation during normal operation, enhancing the stability and reliability of the radar antenna during operation.

[0025] Specifically, the braking power structure includes a first drive structure 41 and a second drive structure 42, which are disposed opposite to each other on both sides of the radar drive component 12 and are respectively connected to the first braking mechanism 31.

[0026] In this embodiment of the utility model, the first drive structure 41 and the second drive structure 42 adopt a symmetrical structural layout, which enables the braking power structure to apply symmetrical driving force to the first braking mechanism 31. This effectively avoids the problems of brake mechanism skewness, jamming or unilateral wear that may be caused by unilateral drive, and ensures that the joint surfaces of the first braking mechanism 31 and the second braking mechanism 32 can make uniform contact. This effectively enhances the balance and stability during the braking process and extends the service life of the braking main structure 3.

[0027] Furthermore, the first drive structure 41 is also provided with a first drive structure body 411 and a first extension 412 for driving the first braking mechanism 31 to move; one end of the first extension 412 is connected to the first drive structure body 411 and the other end is connected to the first braking mechanism 31. The second drive structure 42 is further provided with a second drive structure body 421 and a second extension 422 for driving the first braking mechanism 31 to move; one end of the second extension 422 is connected to the second drive structure body 421 and the other end is connected to the first braking mechanism 31.

[0028] In this embodiment of the present invention, the first drive structure 41 and the second drive structure 42 are preferably electric push rods, and the first extension 412 and the second extension 422 are both push rods. By precisely controlling the extension and retraction of the first extension 412 and the second extension 422, the displacement stroke and final position of the first braking mechanism 31 can be precisely adjusted, thereby precisely controlling the pressure when the first braking mechanism 31 and the second braking mechanism 32 are in contact, and ensuring the reliability of the braking process.

[0029] In this embodiment of the present invention, the first drive structure 41 is further provided with a first drive member connecting portion 413 for connecting the first braking mechanism 31, and the second drive structure 42 is further provided with a second drive member connecting portion 423 for connecting the first braking mechanism 31. The first drive member connecting portion 413 and the second drive member connecting portion 423 are respectively connected to the side of the first extension portion 412 and the second extension portion 422 near the first braking mechanism 31. The first braking mechanism 31 is provided with a second mounting position 317 on the side facing the braking power structure. The two second mounting positions 317 are arranged opposite to each other on both sides of the first braking mechanism 31. The first drive member connecting portion 413 and the second drive member connecting portion 423 are respectively connected to the two second mounting positions 317 to improve the convenience of connecting the first drive structure 41 and the second drive structure 42 with the first braking mechanism 31.

[0030] Furthermore, the braking power structure also includes a first drive motor 43 and a second drive motor 44 for maintaining the power-off braking state; the first drive motor 43 and the second drive motor 44 are respectively disposed on the first drive structure body 411 and the second drive structure body 421, and are rotatably connected to the first extension 412 and the second extension 422 respectively.

[0031] In this embodiment of the utility model, the protection device also includes an electrical control box for controlling the entire protection device. In order to avoid outdoor rain damage and improve the stability of the protection device, the protection device is installed indoors, which is beneficial to extending the service life of the protection device. The electrical control box includes a main control module for processing information and an adjustment knob for adjusting the closing or opening of the circuit breaker. The radar drive unit 12, the first drive motor 43, the second drive motor 44, and the adjustment knob are electrically connected to the main control module, so that the main control module can send instructions to the radar drive unit 12, the first drive motor 43, and the second drive motor 44 to perform effective adjustment.

[0032] In this embodiment of the invention, the braking power structure further includes a first right-angle gearbox, a second right-angle gearbox, a first coupling, and a second coupling. The first extension 412 and the second extension 422 are both threaded push rods. The first drive motor 43 and the second drive motor 44 are rotatably connected to the first right-angle gearbox and the second right-angle gearbox, respectively. One end of the first coupling is connected to the first right-angle gearbox, and the other end is connected to the first extension 412, so that the extension and retraction of the first extension 412 can be controlled by the forward or reverse rotation of the first drive motor 43. One end of the second coupling is connected to the second right-angle gearbox, and the other end is connected to the second extension 422, so that the extension and retraction of the second extension 422 can be controlled by the forward or reverse rotation of the second drive motor 44. In turn, the main control module controls the synchronous extension and retraction of the first extension 412 and the second extension 422 to improve the stability during braking.

[0033] In this embodiment of the invention, the first drive motor 43 and the second drive motor 44 are preferably brake servo motors. The brake servo motor is equipped with an electromagnetic coil, a spring, and a friction plate. The spring and the friction plate are elastically connected. When the brake servo motor is powered on, the electromagnetic coil generates a magnetic force to attract the brake plate and compress the spring to accumulate elastic potential energy, while simultaneously allowing the motor shaft to rotate freely. When the brake servo motor is powered off or the external power supply stops, the magnetic force generated by the electromagnetic coil disappears, and the spring releases its elastic potential energy to quickly push the brake plate to clamp the motor shaft, ensuring that the brake servo motor enters a locked state at this position. The structural design of the brake servo motor adopted in this invention effectively improves the braking stability and reliability of the radar antenna when the motor is powered off or the external power supply stops.

[0034] In this embodiment of the invention, the first drive motor 43 and the second drive motor 44 enter a locked state when the power is cut off or the external power supply is stopped. Since the first extension 412 and the second extension 422 are rotatably connected to the first drive motor 43 and the second drive motor 44 respectively, the first extension 412 and the second extension 422 also enter a locked state when the power is cut off or the external power supply is stopped. Thus, through the double-locking structural design, the braking failure of the protection device in the super typhoon environment is effectively prevented, and the braking stability of the protection device is improved.

[0035] In this embodiment of the invention, the protection device enters manual operation mode by rotating the adjustment knob. The braking power structure further includes a first drive controller, a second drive controller, a closing indicator light, and a closing indicator light. The first and second drive controllers are mounted on the main control module. The closing and closing indicator lights are electrically connected to the main control module. The first drive motor 43 and the second drive motor 44 are electrically connected to the first and second drive controllers, respectively. When the adjustment knob is rotated to the "closing" position, the main control module inputs a preset high-level signal A to the first and second drive controllers. The first and second drive controllers then control the first drive motor 43 and the second drive motor 44, respectively. The drive motor 44 performs a position mode torque limiting function. When the torque reaches the preset value, the first drive motor 43 and the second drive motor 44 decelerate and stop while maintaining continuous torque output. The closing indicator light illuminates normally, and the radar antenna enters a energized standby state, enhancing safety during operation. When the adjustment knob is rotated to the "open" position, the main control module inputs a preset high level B to the first drive controller and the second drive controller. The first drive controller and the second drive controller respectively control the first drive motor 43 and the second drive motor 44 to perform point-to-point positioning. When the main control module detects that the target position has been reached, the opening indicator light illuminates normally, and the radar antenna enters a power-off state, enhancing safety during operation.

[0036] To prevent ineffective braking, the main control module is also equipped with a current detection module. During braking, the current detection module detects a current value based on the tension value of the first extension 412 and the second extension 422. When the detected current value reaches the preset threshold, the main control module cuts off the power supply to the first drive motor 43 and the second drive motor 44 and enters a locked state. The first extension 412 and the second extension 422 are respectively equipped with a first limit switch and a second limit switch for detecting the stroke. The first limit switch and the second limit switch are electrically connected to the main control module. When the braking is released, the first limit switch and the second limit switch respectively detect that the first extension 412 and the second extension 422 have reached the preset position. Then, the main control module cuts off the power supply to the first drive motor 43 and the second drive motor 44 and enters a locked state. This design effectively avoids excessive displacement of the first extension 412 and the second extension 422, which could cause overload of the first drive motor 43 and the second drive motor 44, thereby enhancing the reliability and safety of the radar antenna.

[0037] Furthermore, the first braking mechanism 31 has a first surface 311 on the side facing the second braking mechanism 32, and the second braking mechanism 32 has a second surface 321 on the side facing the first braking mechanism 31, with the first surface 311 parallel to the second surface 321.

[0038] In this embodiment of the utility model, both the first surface 311 and the second surface 321 are designed as planar structures. By making the first surface 311 parallel to the second surface 321, it is beneficial to increase the contact area between the first surface 311 and the second surface 321, so that the first braking mechanism 31 and the second braking mechanism 32 can generate a stable frictional torque, thereby improving braking efficiency and extending the service life of the first braking mechanism 31 and the second braking mechanism 32, and ensuring the long-term stable braking performance of the protection device.

[0039] In some embodiments, in order to further increase the frictional force, the first surface 311 is provided with micro-protrusions extending toward the second surface 321, and the second surface 321 is provided with inwardly recessed micro-grooves. The contact area is increased by the micro-protrusions being embedded in the micro-grooves, which further increases the frictional force between the first braking mechanism 31 and the second braking mechanism 32, and effectively improves the braking efficiency of the protection device.

[0040] Furthermore, the second surface 321 is provided with a first mounting portion 322 extending outward in the direction facing the radar rotating component 11. The first mounting portion 322 is provided with a first limiting hole 3221 penetrating both sides of the second braking mechanism 32. The radar rotating component 11 is provided with a first connecting member 111 and a rotating component body 112. One end of the first connecting member 111 is connected to the rotating component body 112, and the other end is in clearance fit with the first limiting hole 3221.

[0041] In this embodiment of the present invention, the first connecting member 111 is preferably a fixed flange. The first connecting member 111 has a flange protrusion on the side facing the second surface 321. The flange protrusion is clearance-fitted with the first limiting hole 3221, which facilitates the connection between the first connecting member 111 and the radar drive member 12. At the same time, it allows the first connecting member 111 to abut against the first mounting part 322, improving the smoothness of the connection. In this embodiment of the present invention, the flange protrusion is provided with a first mounting cavity 1111. The radar drive member 12 is preferably a servo motor. The rotating shaft of the radar drive member 12 is rotatably connected in the first mounting cavity 1111 to drive the radar rotating member 11 to rotate. In this embodiment of the present invention, a vertical safety gap is formed between the rotating body 112 and the first braking mechanism 31. By setting the vertical safety gap to be greater than 0, it is ensured that the first braking mechanism 31 will not interfere with other components when the first extension portion 412 and the second extension portion 422 have the maximum extension amount, thereby improving the reliability of the protection device during the braking process.

[0042] Furthermore, the radar rotating component 11 is also provided with a rotation limiting component 113 for driving the second braking mechanism 32 to rotate synchronously, and the first mounting part 322 is also provided with a first mounting position 323 on the side facing the radar rotating component 11, and the rotation limiting component 113 is detachably connected in the first mounting position 323.

[0043] In this embodiment of the present invention, the rotation limiting member 113 is preferably the first bolt, and the first mounting position 323 is preferably the first connecting through hole. The rotation limiting member 113 passes through the rotating body 112 and the first connecting member 111 and is connected in the first mounting position 323 to ensure that the second braking mechanism 32 is fixedly connected to the radar rotating member 11, so that the radar rotating member 11 can be effectively braked by the first braking mechanism 31 pressing against the second braking mechanism 32, thereby improving the reliability of the protection device during the braking process.

[0044] Furthermore, the first braking mechanism 31 is provided with a braking part 312 for pressing against the second surface 321 and a second limiting part 313 passing through both sides of the first braking mechanism 31. The braking part 312 is located outside the second limiting part 313. The second limiting part 313 is movably connected to the first mounting part 322, so that the first braking mechanism 31 will not interfere with the first mounting part 322 during the braking process, thereby ensuring that the braking part 312 can smoothly press against or disengage from the second surface 321 and improving the smoothness of the protection device during the braking process.

[0045] In this embodiment of the present invention, the second limiting part 313 is preferably a through hole, and a horizontal gap is formed between the second limiting part 313 and the first connecting member 111. In order to ensure that the first braking mechanism 31 does not interfere with the first connecting member 111 during the braking process, the horizontal gap needs to be set to be greater than 0, that is, the diameter of the second limiting part 313 is greater than the maximum diameter of the first connecting member 111, and the difference between the diameter of the second limiting part 313 and the maximum diameter of the first connecting member 111 is greater than 0, so as to improve the reliability of the protection device during the braking process.

[0046] Furthermore, the protection device also includes a first limiting member 6 for limiting the displacement of the first braking mechanism 31, and at least two first limiting members 6 are connected to the outer side of the brake support 2 facing the first braking mechanism 31; the first braking mechanism 31 is provided with a second limiting hole 314 that passes through both sides of the first braking mechanism 31 for sliding connection on the first limiting member 6.

[0047] In this embodiment of the utility model, the number of first limiting members 6 is preferably 4. The first limiting member 6 is preferably a smooth guide post with a thread at one end. The 4 first limiting members 6 are fixedly connected to the brake support seat 2 through the threaded end to enhance the vertical stability of the first limiting member 6 and ensure the stability of the first braking mechanism 31 during the movement process, so that the protection device can brake smoothly.

[0048] Furthermore, the first braking mechanism 31 and the second braking mechanism 32 adopt a split structure design. The first braking mechanism 31 includes a first braking element 315 and a second braking element 316. The first braking element 315 and the second braking element 316 are detachably connected to form the first braking mechanism 31. The second braking mechanism 32 includes a third braking element 324 and a fourth braking element 325, which are detachably connected to form the second braking mechanism 32.

[0049] In this embodiment of the present invention, the first braking mechanism 31 includes a first connecting block 318 with a flat bottom surface. The connection between the first braking member 315 and the second braking member 316 is provided with a first planar slot and a second planar slot with a flat bottom surface, respectively. The two ends of the first connecting block 318 are respectively inserted into the first planar slot and the second planar slot, and the first connecting block 318 is fastened to the first braking member 315 and the second braking member 316 by a second threaded component, so that the flat surface of the first connecting block 318 abuts against the bottom surface of the first planar slot and the second planar slot, thereby improving the flatness and stability of the first braking member 315 and the second braking member 316 after connection.

[0050] The second braking mechanism 32 also includes a second connecting block 326 with a flat bottom surface. The connection points of the third braking member 324 and the fourth braking member 325 are respectively provided with a third plane slot and a fourth plane slot with a flat bottom surface. The two ends of the second connecting block 326 are respectively inserted into the third plane slot and the fourth plane slot, so that the plane of the second connecting block 326 abuts against the bottom surface of the third plane slot and the fourth plane slot, thereby improving the flatness and stability of the third braking member 324 and the fourth braking member 325 after connection.

[0051] In this embodiment of the present invention, the overall structure of the first braking mechanism 31 and the second braking mechanism 32 is preferably made of 304 stainless steel. After passivation treatment, they can effectively perform friction braking through contact and enhance the corrosion resistance of the first braking mechanism 31 and the second braking mechanism 32, thereby extending the service life of the first braking mechanism 31 and the second braking mechanism 32.

[0052] In this embodiment of the present invention, the braking power structure is further provided with a first quick-release connector 45 and a second quick-release connector 46; one end of the first quick-release connector 45 and the second quick-release connector 46 are respectively detachably connected to the brake support seat 2, and the other end is respectively detachably connected to the first drive structure body 411 and the second drive structure body 421, so as to improve the convenience of installation of the braking power structure.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
