Description

Technical Field

[0001] This utility model patent relates to the field of meteorological equipment technology, specifically to a lightning rod structure mounted on a meteorological radar. Background Technology

[0002] Weather radar, as a core device for monitoring atmospheric physical phenomena (such as precipitation, storms, and turbulence), is widely used in weather forecasting, disaster prevention and mitigation, and other fields. It is typically installed in open, high-altitude areas or rooftops—areas without obstructions—to ensure the continuity and accuracy of the detection signal. However, these environments also make them high-risk targets for lightning strikes. Therefore, equipping weather radar with reliable lightning protection devices to prevent damage from lightning strikes and ensure its continuous and stable operation is an important research direction in the field of meteorological equipment technology.

[0003] Currently, most lightning protection devices used in weather radars are traditional lightning rod structures. Their core principle is based on the "point discharge" effect, where lightning charges are guided through a metal tip and then the current is conducted to the ground via a conductor, thus preventing direct lightning strikes to the radar body. The main purpose is to create a "lightning protection barrier," reducing the risk of hardware damage and short circuits caused by lightning strikes, and ensuring the basic operational safety of the equipment. Summary of the Invention

[0004] To address some or all of the aforementioned technical problems, this application provides a lightning rod structure mounted on a weather radar, which has the technical advantages of lightning protection and avoiding electromagnetic interference.

[0005] A lightning rod structure mounted on a weather radar includes: an operational radar and a base platform, the operational radar being fixedly mounted on the base platform; a structural sleeve mounted on the base platform and positioned behind the operational radar; a fixed sleeve disposed within the structural sleeve, the fixed sleeve having a track groove; a lightning protection bracket slidably mounted within the fixed sleeve, the lightning protection bracket including a lightning rod body, a coupling, and deployable arms, the lightning rod body and the coupling being slidably mounted within the track groove, two deployable arms mounted on the coupling, the two deployable arms being respectively positioned on both sides of the lightning rod body; two traction ropes, the traction ropes being respectively connected to the lightning rod body and the deployable arms; and a drive screw, the drive screw being drivenly connected to the lightning rod body, the lightning rod body and the drive screw having drive-fit threads, the drive screw being connected to a drive mechanism.

[0006] By adopting the above technical solution, the drive mechanism in this structure drives the drive screw to rotate, and uses the threaded engagement to drive the lightning rod body to slide along the track groove of the fixed sleeve. At the same time, the traction rope controls the deployment arm to unfold or retract under the action of the coupling, realizing the adjustment of the height of the lightning rod body and the protection range. During this process, the structural sleeve is set behind the working radar. Combined with its special structure, it can effectively guide lightning through the conductive line to the grounding structure, avoiding lightning strikes that burn out the equipment, while reducing electromagnetic interference to the radar. It has the technical advantages of reliable lightning protection, strong anti-interference, and flexible adjustment.

[0007] Optionally, an assembly base is provided on the lower end face of the structural sleeve. The assembly base is a high-voltage resistant insulating ceramic base. The assembly base is fixedly installed on the edge of the upper end face of the base platform. The height of the assembly base is not less than 5 cm. A lead-out interface is provided on the edge of the upper end face of the assembly base. A conductive wire is constrained in the lead-out interface. The two ends of the conductive wire are respectively connected to the fixed sleeve and the grounding structure. The distance between the grounding structure and the base platform is not less than 5 meters. A flange end is provided on the outer side of the structural sleeve. The flange end is fixedly connected to the assembly base.

[0008] By adopting the above technical solution, the structural sleeve is fixedly connected to the assembly base through the flange end. The assembly base (with a height of not less than 5 cm) made of high voltage resistant insulating ceramic material can improve the insulation and stability of the overall structure, and its fixation to the edge of the base platform can optimize the layout. The conductive wire in the lead-out interface connects the fixed sleeve and the grounding structure (with a spacing of not less than 5 meters), which can safely guide the lightning current to the ground, ensuring the reliability of the lightning protection path and enhancing the structural safety and insulation protection effect.

[0009] Optionally, the structural sleeve adopts a ring-shaped structure, which includes an insulating ceramic structural support layer, a lead interlayer, a silicon carbide interlayer, and a ferrite structural support layer arranged sequentially from the inside to the outside; the upper end face of the structural sleeve is provided with a trumpet-shaped opening.

[0010] By adopting the above technical solution, the circular bushing, with its insulating ceramic support layer, lead interlayer, silicon carbide interlayer, and ferrite support layer arranged sequentially from the inside to the outside, can work together to reduce the interference intensity of 3-10GHz radar electromagnetic waves by more than 80% compared with traditional metal bushings, thus reducing electromagnetic interference to weather radar. The horn-shaped opening on the upper end facilitates the extension and retraction of the lightning protection bracket, improving the practicality of the structure.

[0011] Optionally, the outer surface of the fixed sleeve abuts against the inner wall of the structural sleeve; the track groove includes a screw groove and a slide rail groove, the screw groove and the slide rail groove are coincidentally arranged, and the screw groove is threadedly connected to the lightning rod body; the slide rail groove is slidably connected to the coupling and the unfolding support arm; an annular groove is provided at the lower end of the lightning rod body, and the coupling is rotatably connected to the annular groove; wherein, a drive window is provided on the lower end face of the structural sleeve and the fixed sleeve, and the lightning rod body is driven connected to the drive screw through the drive window; the drive mechanism includes a drive motor and a hydraulic drive rod.

[0012] By adopting the above technical solutions, the outer side of the fixed sleeve and the inner wall of the structural sleeve can be closely fitted and abutted, which can enhance the overall structural stability; the screw groove of the track groove is threadedly engaged with the lightning rod body, and the sliding rail groove provides sliding constraint for the coupling and the unfolding support arm. Combined with the rotational connection between the annular groove at the lower end of the lightning rod body and the coupling, the stable sliding and coordinated movement of the lightning rod body and the unfolding support arm can be achieved; the drive window on the lower end face of the structural sleeve and the fixed sleeve enables the lightning rod body to be effectively driven and connected to the drive screw (connecting the drive motor and hydraulic drive rod), ensuring the accuracy and reliability of structural adjustment.

[0013] Optionally, separation springs are provided on both sides of the lightning rod body, and the length of the separation springs is greater than the distance between the extended support arm and the lightning rod body when they are parallel.

[0014] By adopting the above technical solution, the separation springs on both sides of the lightning rod body are longer than the distance between the extended arm and the main body of the lightning rod when they are parallel. They can provide elastic thrust during the retraction of the extended arm, assist the arm in returning to its original position smoothly, and at the same time form a buffer when the arm is extended, thereby enhancing the stability and reliability of the structure.

[0015] Optionally, a spool for winding and unwinding the traction rope is fixedly installed at the upper end of the lightning rod body, and the two traction ropes are wound and fixedly installed on the spool. The traction ropes are made of wire rope lock.

[0016] By adopting the above technical solution, the spool at the upper end of the lightning rod body can realize the operation of raising and lowering the two traction ropes. The traction ropes made of steel wire rope lock material are wound and fixed on the spool, which can stably connect the lightning rod body and the deployable arm. When the drive mechanism drives the lightning rod body to slide up and down, the raising and lowering of the deployable arm is precisely controlled by raising and lowering the spool ropes, ensuring the reliability and stability of the arm's movement.

[0017] Optionally, the upper end face of the structural sleeve is provided with a flap for closed protection, and the flap is connected to the structural sleeve by a torque spring.

[0018] By adopting the above technical solution, the flip cover on the upper end face of the structural bushing can be closed and opened under the drive of the torque spring: when the lightning rod structure is in a non-working state, the flip cover is closed, which can protect the internal extended support arm, lightning rod body and other components, and reduce the corrosion of the structure by external dust, rain and snow; when lightning protection operation is required, the torque spring drives the flip cover to open, providing a channel for the extension of the extended support arm, which not only ensures the safety of the structure in a non-working state, but also does not affect the normal operation during lightning protection, thus improving the overall protection and adaptability of the structure.

[0019] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects of a lightning rod structure mounted on a weather radar:

[0020] 1. Strong anti-electromagnetic interference capability: The structural sleeve adopts a composite layer design of insulating ceramic, lead, silicon carbide and ferrite, and is set behind the radar. Compared with traditional metal sleeves, this structural sleeve reduces the interference intensity of 3-10GHz radar electromagnetic waves by more than 80%, reducing interference to radar electromagnetic waves and ensuring detection accuracy.

[0021] 2. Reliable lightning protection performance: The height of the lightning rod body can be adjusted by the drive mechanism, and the extension arm can be used to expand the protection range with the help of the separation spring and the traction rope. Combined with the conductive wire and the long-distance grounding structure, the grounding resistance of the grounding structure is ≤10Ω, which ensures that the lightning current is safely conducted to the ground and avoids the equipment from burning out. Compared with traditional lightning rods, the continuous working time of the radar in the lightning environment is extended by ≥90%.

[0022] 3. Excellent structural stability and adaptability: The insulating ceramic assembly base and flange end fixation enhance overall stability; the separation spring assists in the arm reset, and the wire rope lock traction ensures reliable operation; the flip cover achieves closed protection under the drive of the torque spring, reducing environmental erosion and improving protection capabilities in non-working states.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model patent clearer, the technical solutions of the embodiments of this utility model patent will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model patent, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model patent are within the scope of protection of this utility model patent.

[0035] Referring to the accompanying drawings, this application discloses a lightning rod structure mounted on a weather radar. To make the technical solution of this utility model clearer, the structure will be described in detail below with reference to the application documents and several embodiments.

[0036] Example 1

[0037] A lightning rod structure mounted on a weather radar includes an operational radar 1, a base platform 11, a structural sleeve 2, a fixing sleeve 3, a lightning protection bracket 4, a traction rope 5, and a drive screw 6.

[0038] The working radar 1 is fixedly installed on the base platform 11; the structural sleeve 2 is installed on the base platform 11 and located behind the working radar 1; the fixed sleeve 3 is set inside the structural sleeve 2, and its interior is provided with a track groove; the lightning protection bracket 4 is slidably installed inside the fixed sleeve 3, including a lightning rod body 41, a coupling 42 and two deployable arms 43, wherein the lightning rod body 41 and the coupling 42 are slidably assembled in the track groove, and the two deployable arms 43 are installed on both sides of the lightning rod body 41 through the coupling 42; the tail end of the lightning rod body 41 slides against the inner wall of the fixed sleeve 3; two traction ropes 5 respectively connect the lightning rod body 41 and the deployable arms 43; the drive screw 6 is drivenly connected to the lightning rod body 41 through a threaded engagement, and the drive screw 6 is connected to the drive mechanism 7.

[0039] When the drive mechanism 7 drives the drive screw 6 to rotate, the screw thread engages with the lightning rod body 41 to slide up and down along the track groove of the fixed sleeve 3. At the same time, the traction rope 5 moves with the sliding of the lightning rod body 41, controlling the deployment arm 43 to expand or retract synchronously under the action of the coupling 42, so as to achieve flexible adjustment of the height and protection range of the lightning rod body 41. The continuous sliding contact between the tail end of the lightning rod body 41 and the fixed sleeve 3 ensures that there is no deviation during the sliding process.

[0040] By adjusting the height of the lightning rod body 41 and the unfolding angle of the lightning rod bracket 4, the protection requirements of different lightning intensity scenarios can be adapted; the structural sleeve 2 is located behind the radar to reduce the obstruction of radar signals.

[0041] It enables dynamic adjustment of the lightning protection range, taking into account both the detection needs of meteorological radar and lightning protection safety, and features flexible adjustment and strong adaptability.

[0042] Example 2

[0043] Based on Embodiment 1, the lower end face of the structural sleeve 2 is provided with an assembly base 21, and the outer side of the structural sleeve 2 is provided with a flange end 24.

[0044] The assembly base 21 is made of high-voltage resistant insulating ceramic material and is fixed to the upper edge of the base platform 11 with a height of not less than 5 cm. The upper edge of the assembly base 21 is provided with an outlet interface, and the two ends of the internally constrained conductive wire 22 are respectively connected to the fixing sleeve 3 and the grounding structure 23 (the distance between the grounding structure 23 and the base platform 11 is not less than 5 meters, and the grounding resistance is ≤10Ω). The flange end 24 fixes the structural sleeve 2 to the assembly base 21. The tail end of the lightning rod body 41 always slides against the inner wall of the fixing sleeve 3.

[0045] After the lightning is guided by the lightning rod body 41, the current is transmitted sequentially through the fixed sleeve 3 and the conductive wire 22 to the grounding structure 23. A safety distance of more than 5 meters is used to prevent the current from spreading to the base platform 11 and the working radar 1. The high-voltage resistant insulating ceramic base blocks the current conduction path to the base platform 11, and the flange end 24 enhances the connection stability between the structural sleeve 2 and the base. The continuous sliding contact between the tail end of the lightning rod body 41 and the fixed sleeve 3 provides additional guiding constraints for the raising and lowering of the lightning rod body 41, ensuring that it does not deviate or shake during the sliding process.

[0046] Lightning current can be safely conducted to the ground without the risk of leakage; the design of the insulating ceramic base and flange end 24 improves the overall structure's resistance to high voltage and stability; the sliding contact at the tail end of the lightning rod body 41, combined with the track groove constraint, makes the lifting action more stable and avoids component wear or poor contact caused by shaking.

[0047] Based on strengthening lightning protection safety (through insulation and long-distance grounding), the stability and accuracy of the structure's operation are further improved by sliding contact between the tail end of the lightning rod body 41 and the fixed sleeve 3, reducing the risk of mechanical failure and balancing lightning protection effect and structural durability.

[0048] Example 3

[0049] Based on Example 2, the structural sleeve 2 further adopts a circular structure and has a flared opening on the upper end face.

[0050] The annular structure consists of an insulating ceramic support layer 25, a lead interlayer 26, a silicon carbide interlayer 27, and a ferrite support layer 28 (each layer is 1-5mm thick, and the initial permeability of the ferrite is ≥1000) from the inside out. The horn-shaped opening is located at the upper end of the structural sleeve 2, corresponding to the track groove position of the internal fixed sleeve 3. The tail end of the lightning rod body 41 is always in sliding contact with the fixed sleeve 3.

[0051] The insulating ceramic support layer provides structural strength and insulation, the lead interlayer 26 reflects radar electromagnetic waves, and the silicon carbide interlayer 27 and ferrite structural support layer 28 absorb stray electromagnetic signals. The four-layer structure works together to reduce the intensity of radar electromagnetic wave interference in the 3-10GHz frequency band by more than 85%. The horn-shaped opening provides sufficient space for the extension and retraction of the lightning rod bracket 4 to avoid structural jamming. The sliding contact at the tail end of the lightning rod body 41 ensures stable lifting and lowering, and forms multiple constraints with the track groove and sleeve structure.

[0052] Significantly reduces the interference of the lightning protection structure on radar electromagnetic waves, ensuring the accuracy of the detection signal (error ≤ 0.5%); the arm unfolding / retracting process is smooth and without mechanical obstruction; the sliding stability of the lightning rod body 41 is further enhanced.

[0053] Combining electromagnetic interference resistance with structural practicality, it solves the problem of traditional metal lightning arresters interfering with radar signals, while continuously ensuring operational stability through a tail-end contact design.

[0054] Example 4

[0055] Based on embodiment 3, the fixing sleeve 3 is further fitted and abutted against the inner wall of the structural sleeve 2, and the structure of the track groove and drive window 8 is optimized.

[0056] The outer side of the fixed sleeve 3 is completely fitted with the inner wall of the structural sleeve 2; the track groove includes a screw groove 32 and a slide rail groove 33 that are arranged in an overlapping manner. The screw groove 32 is threadedly engaged with the lightning rod body 41, and the slide rail groove 33 constrains the coupling 42 and the unfolding support arm 43 to slide; the lower end of the lightning rod body 41 is provided with an annular groove, and the coupling 42 is rotatably connected to the annular groove; the lower end face of the structural sleeve 2 and the fixed sleeve 3 is provided with a drive window 8. The lightning rod body 41 is connected to the drive screw 6 through the window. The drive mechanism 7 includes a drive motor (rated power 0.5-1.5kW) and a hydraulic drive rod (maximum thrust ≥5000N); the tail end of the lightning rod body 41 is always in sliding contact with the fixed sleeve 3.

[0057] The fixed sleeve 3 fits snugly with the structural sleeve 2 to enhance overall rigidity; the screw groove 32 drives the lightning rod body 41 to rise and fall through the threaded transmission; the slide rail groove 33 restricts the sliding trajectory of the coupling 42 and the unfolding support arm 43; the annular groove and the rotational connection of the coupling 42 ensure that the support arm can be flexibly unfolded; the drive motor provides precise speed control, the hydraulic drive rod enhances the load capacity, and the two work together to achieve stable drive through the drive window 8; the sliding contact at the tail end of the lightning rod body 41, combined with the constraint of the track groove, ensures that there is no deviation during the lifting process.

[0058] The sliding and rotating movements of the lightning rod body 41 and the lightning rod bracket 4 are stable and without deviation, the driving process is responsive and has a strong load capacity; the tail end abutment design and multiple structural constraints work together to further reduce the probability of mechanical failure.

[0059] With high structural precision and strong operational reliability, it is suitable for high-frequency regulation requirements under complex weather conditions, and the tail-end contact design provides a basic guarantee for overall stability.

[0060] The coupling 42 includes a slider, a retaining ring, and a rotating shaft, with the retaining ring and rotating shaft fixedly installed inside the slider. The slider slides against the track, and the retaining ring is rotated and constrained by the annular groove. Two retaining rings are provided, and each retaining ring is rotatably connected to a corresponding unfolding support arm 43.

[0061] Example 5

[0062] Based on embodiment 4, furthermore, separation springs 9 are provided on both sides of the lightning rod body 41.

[0063] The two ends of the separation spring 9 are respectively connected to the lightning rod body 41 and the unfolding support arm 43, and its length is greater than the distance between the unfolding support arm 43 and the lightning rod body 41 when they are parallel; the tail end of the lightning rod body 41 is always in sliding contact with the fixed sleeve 3.

[0064] When the lightning rod bracket 4 is retracted, the release spring 9 is compressed and generates elastic thrust, which helps the support arm overcome frictional resistance and reset (retraction time ≤ 2 seconds); when the support arm is extended, the spring gradually extends, and the elasticity buffers the impact force of the extension of the support arm (reducing it by more than 30%); the sliding contact at the tail end of the lightning rod body 41 ensures that the position of the body itself does not shift under the action of the spring force, forming a stable cooperation with the movement of the support arm.

[0065] The arm retracts more smoothly without jamming; the impact force is reduced when it is extended, thus reducing wear on components; the main body 41 of the lightning rod remains stable and slides without shaking under the action of spring force.

[0066] To improve the stability and service life of the structure and reduce the risk of mechanical failure, the tail end abutment design provides support for the stable transmission of spring force.

[0067] Example 6

[0068] Based on embodiment 5, the lightning rod body 41 is further provided with a spool 44 at the upper end, and the traction rope 5 is a wire rope lock.

[0069] The spool 44 is fixed to the upper end of the lightning rod body 41. Two traction ropes 5 are wrapped around and fixed to the spool 44, and the two ends of the ropes are respectively connected to the spool 44 and the unfolding support arm 43. The material is steel wire rope lock (diameter 3-6mm, minimum breaking tensile force ≥20kN). The tail end of the lightning rod body 41 is always in sliding contact with the fixed sleeve 3.

[0070] When the lightning rod body 41 is raised or lowered, the spool 44 rotates synchronously to retract and extend the traction rope 5: during ascent, the rope slacks, and the support arm unfolds under the action of the separation spring 9; during descent, the rope tightens, pulling the support arm to overcome the spring force and retract. The high strength characteristics of the wire rope lock ensure stable connection and eliminate the risk of breakage; the sliding contact at the tail end of the lightning rod body 41 ensures smooth raising and lowering, providing a stable foundation for rope retraction and extension.

[0071] The control precision of the outrigger's extension and retraction is improved, with no rope slippage or breakage and consistent action response; the main body's sliding stability ensures that the rope's extension and retraction process is smooth and without jamming.

[0072] The traction mechanism is durable, precise in control, and adaptable to long-term use in complex outdoor environments. The tail-end abutment design provides structural support for the stable operation of the traction system.

[0073] Example 7

[0074] Based on embodiment 6, the upper end face of the structural sleeve 2 is provided with a flip cover 51, which is connected to the structural sleeve 2 by a torque spring 52.

[0075] The flip cover 51 covers the flared opening at the upper end of the structural sleeve 2, and the torque spring 52 (rated torque 0.5-2 N·m) connects the flip cover 51 to the side wall of the structural sleeve 2; the tail end of the lightning rod body 41 is always in sliding contact with the fixed sleeve 3.

[0076] In non-lightning protection mode, the torque spring 52 drives the flip cover 51 to close, blocking the flared opening and preventing dust, rain and snow from entering the interior of the structural sleeve 2, thus extending the service life of the components by ≥1.5 times. When the lightning rod body 41 rises and unfolds, its top pushes the flip cover 51 to overcome the spring force and open, providing a channel for the extension of the support arm. During this process, the sliding contact at the tail end of the lightning rod body 41 ensures a smooth rising action and avoids deviation when pushing the flip cover 51. After the lightning protection is completed, the lightning rod body 41 descends, and the flip cover 51 automatically closes under the action of the torque spring 52.

[0077] When not in operation, internal components (such as the extended support arm 43 and the lightning rod body 41) are protected from environmental corrosion; when in operation, the flip cover 51 opens automatically without affecting the lightning protection action; the stability of the main body lifting process ensures that the flip cover 51 opens and closes smoothly.

[0078] The enhanced structure provides protection and adaptability, extends the service life of components, reduces maintenance costs, and the tail-end abutment design provides stable support for the coordinated movement of the flip cover 51 and the main body.

[0079] The above embodiments progress step by step from basic structure to optimized design, covering all the technical features of the claims. Through the core design that "the tail end of the lightning rod body 41 is always in sliding contact with the fixed sleeve 3" and in coordination with other structures, the core advantages of "reliable lightning protection, resistance to electromagnetic interference, flexible adjustment and strong protection" are achieved.

[0080] Implementation principle of the embodiments of this application

[0081] When facing the risk of lightning strikes, the drive mechanism 7 (drive motor or hydraulic drive rod) drives the drive screw 6 to rotate, using the threaded engagement to drive the lightning rod body 41 to slide upward along the track groove of the fixed sleeve 3. The tail end of the lightning rod body 41 always slides and abuts against the fixed sleeve 3, ensuring stability and guidance during the sliding process. At this time, the upper spool 44 of the lightning rod body 41 releases the traction rope 5 (3-6mm in diameter) made of wire rope lock material. The separation springs 9 on both sides of the lightning rod body 41, because their length is greater than the distance between the unfolding support arm 43 and the lightning rod body 41 when parallel, release elastic force to push the unfolding support arm 43 outward with the coupling 42 as the fulcrum, expanding the lightning protection range. Simultaneously, the flip cover 51 on the upper surface of the structural sleeve 2 opens under the push of the lightning rod body 41, overcoming the force of the torque spring 52 (0.5-2 N·m), providing a channel for the lightning protection bracket 4 to extend.

[0082] Once deployed, the main body 41 of the lightning rod and the support arm form an integrated lightning protection structure. Utilizing the tip discharge effect, the lightning charge is guided, and the current is sequentially transmitted through the fixed sleeve 3, the conductive wire 22 leading out from the assembly base 21, and finally to the grounding structure 23 (with a distance of not less than 5 meters from the base platform 11 and a grounding resistance ≤10Ω), ensuring the safe introduction of the lightning current. During this process, the insulating ceramic support layer 25, lead interlayer 26, silicon carbide interlayer 27, and ferrite support layer 28 (initial permeability ≥1000) of the structural sleeve 2 work synergistically. Combined with its location behind the operating radar 1, this reduces radar electromagnetic interference in the 3-10GHz frequency band by more than 85%. The high-voltage resistant insulating ceramic assembly base 21 is fixed via the flange end 24, enhancing overall insulation and stability. The close contact between the fixed sleeve 3 and the structural sleeve 2, along with the constraint design of the track groove, and the continuous sliding contact between the tail end of the lightning rod main body 41 and the fixed sleeve 3, ensure precise coordination of all components.

[0083] When lightning protection is not required, the drive mechanism 7 reverses its direction, and the main body 41 of the lightning rod slides downward along the track groove. Its tail end always maintains sliding contact with the fixed sleeve 3 to ensure a smooth descent. The spool 44 retracts the traction rope 5 and pulls the extension arm 43 to overcome the elastic force of the separation spring 9 and retract (time ≤ 2 seconds). The flip cover 51 at the upper end of the structural sleeve 2 automatically closes under the action of the torque spring 52, protecting the internal components, thereby achieving reliable lightning protection and stable operation of the weather radar in complex environments.
