Description

Technical Field

[0001] This utility model patent relates to the field of tower weather station technology, specifically to a lightning protection structure applied to tower weather support. Background Technology

[0002] An automatic weather station is a weather station built in a specific area according to needs. It can automatically detect multiple elements, generate reports automatically without human intervention, and transmit the detected data to the central station on a regular basis. "This automatic weather station is equipped with various atmospheric observation instruments, such as wind speed sensors, wind direction sensors, air temperature, humidity, and air pressure sensors."

[0003] Most weather towers are located in high-altitude areas such as mountains, and are frequently struck by natural disasters such as lightning during rainy days. Existing lightning rods and other lightning protection devices often require installation on high poles, which may lead to problems such as inconvenience in maintenance and upkeep.

[0004] Meanwhile, referring to Chinese Patent Application No. CN202323130375.3, a structure for a meteorological tower lightning rod is disclosed. By lifting and moving the lifting rod, the placement plate is moved, and the movement of the placement plate causes the lightning rod body to move upward, so that the entire device body is in a higher position. When it is necessary to inspect the lightning rod body, the fixed base and the fixed block are disengaged by rotating the screw, so that the lightning rod body of the device body can be touched, thereby facilitating inspection and maintenance by the inspection personnel. Summary of the Invention

[0005] In order to solve some or all of the above-mentioned technical problems, this application provides a lightning protection structure for tower-type meteorological support, which has the technical advantages of realizing lightning protection grounding, debris removal and winding and cutting.

[0006] A lightning protection structure for a tower-type meteorological support includes: a connecting assembly mounted on the tower-type meteorological support; a lightning protection module mounted on the connecting assembly; a wiring module connected to the lightning protection module and mounted on the tower-type meteorological support via a cable tray; and a grounding structure fixedly connected to the wiring module. The wiring module contains a connecting wire, and a ceramic sleeve, a rubber tube, and a protective shell are sequentially sleeved on the outside of the connecting wire.

[0007] By adopting the above technical solutions, lightning protection for tower-type weather stations can be achieved.

[0008] To avoid the technical defects of meteorological equipment installed on tower meteorological supports being vulnerable to damage when struck by lightning.

[0009] Optionally, the connecting assembly includes a flange end, which is fixedly connected to a flange interface on the tower meteorological support.

[0010] By adopting the above technical solution and using the flange end connection mode, the technical solution is mature and the manufacturing cost is low.

[0011] Optionally, the connecting assembly further includes a positioning clamp installed on the flange end. The positioning clamp includes a reference plate and a rubber pad. The connecting end of the reference plate wraps around the rubber pad. The functional end of the reference plate is connected to the flange end by a fastening bolt. The rubber pad abuts against the tower-type meteorological support. The rubber pad is provided with anti-slip texture.

[0012] By adopting the above technical solution, the tower-type meteorological support can be installed and fixed. For some tower supports without flange ends, a constraint-fitting assembly mode is adopted to avoid modifying the design of the tower support, reduce the assembly cycle and construction process.

[0013] Optionally, the lightning protection module includes an extension sleeve, a connecting sleeve mounted on the extension sleeve, a wind cup mounted on the connecting sleeve, and a lightning rod fitted inside the connecting sleeve. The extension sleeve is fixedly mounted on the flange end, and a wiring opening is provided on one side of the extension sleeve. The extension sleeve is made of ceramic. The connecting sleeve is assembled and connected to the extension sleeve via a ball bearing. The wind cup includes a first cutting blade fixedly connected to the connecting sleeve and a semi-circular spherical shell fixedly connected to the first cutting blade. The first cutting blade is horizontally positioned. The lightning rod includes a grounding main pin and a supporting secondary pin. The supporting secondary pins are arranged in an umbrella shape and fixedly connected to the grounding main pin. The grounding main pin passes through and is located in the connecting sleeve, and the supporting secondary pins are located on the upper side of the connecting sleeve.

[0014] By adopting the above technical solution, the lightning protection module can be used to guide lightning strike protection and prevent tree branches from getting stuck on the lightning rod or kite lines from getting tangled, which could lead to fires from fallen branches and leaves or damage to other equipment that gets tangled in the kite lines during a lightning strike.

[0015] The wind cup design generates air turbulence, blowing away branches and leaves that have fallen onto the lightning rod. When kite lines, plastic bags, or other debris become entangled, the first cutting blade in the wind cup rotates around the connecting sleeve to cut them off. This prevents the lightning rod and the meteorological monitoring equipment mounted on the tower from becoming entangled together. When the lightning rod is struck by lightning, the entanglement could damage the meteorological monitoring equipment.

[0016] Optionally, a second sleeve is fitted between the connecting sleeve and the ball bearing. A first gear is fitted at the lower end of the connecting sleeve, and a second gear is fitted at the lower end of the second sleeve. The first gear is connected to the second gear through a reduction gear set, which is installed inside the ceramic sleeve. The upper end face of the second sleeve is convenient for setting a second cutting blade, which is lower than the height of the wind cup.

[0017] By adopting the above technical solution and using a reduction gear set to reduce the rotational speed, the operating power of the second cutting blade is improved.

[0018] Optionally, the connecting wire passes through the wiring opening and is fixedly connected to the grounding main pin; the upper end face of the ceramic sleeve is higher than the flange end; the thickness of the rubber tube is not less than five centimeters; and a beam plate is fixedly installed on the outer side of the lower end face of the protective shell.

[0019] By adopting the above technical solution and using a protective sleeve approach, the design requirements for both structural insulation and strength are taken into account.

[0020] Optionally, the grounding structure includes a concrete base, a reinforcing cage disposed in the concrete base, and base bolts disposed on the concrete base. The lower end face of the reinforcing cage extends more than 0.5 meters beyond the lower end face of the concrete base, and the beam plate is fixedly connected to the base bolts.

[0021] Optionally, the cable tray includes a connecting beam, with clamps installed at both ends of the connecting beam, and the clamps are fixedly connected to the tower-type meteorological support and the protective shell, respectively.

[0022] Optionally, the ceramic sleeve and the rubber tube penetrate the concrete base, with the lower end of the ceramic sleeve and the rubber tube being more than 0.2 meters above the ground. The connecting wire is tied to the reinforcing cage, and the periphery of the reinforcing cage is filled with an ion-releasing agent and a drag-reducing agent.

[0023] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects for lightning protection structures applied to tower-type meteorological supports:

[0024] This application provides a lightning protection structure for tower meteorological support. Through the synergistic effect of connecting components, lightning protection modules, wiring modules and grounding structures, it solves the problem of easy burnout of tower meteorological station equipment when struck by lightning, and also has the functions of debris cleaning and entanglement cutting.

[0025] The lightning protection equipment for tower-type meteorological supports has technical advantages such as lightning protection grounding guidance, lightning rod debris removal, winding and cutting, and insulation protection.

[0026] When the wind cup rotates, the turbulent airflow it generates creates irregular forces on the branches and leaves that have fallen onto the lightning rod, making it easier to blow off any attached debris.

[0027] The system is equipped with a first and a second cutting blade to separate and cut the connections between the wires wrapped around the lightning rod, the plastic bags, and other structures on the device. This prevents lightning energy from damaging other meteorological monitoring equipment connected to the lightning rod during a lightning strike. Attached Figure Description

[0040] 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.

[0041] This application discloses a lightning protection structure applied to a tower-type meteorological support 6.

[0042] Reference Figure 1 A lightning protection structure for use in a tower-type meteorological support 6 includes a connecting component 1, a lightning protection module 2, a wiring module 3, and a grounding structure 4.

[0043] A tower-type meteorological support 6 is installed on the grounding structure 4, and meteorological monitoring equipment 7 can be installed on the tower-type meteorological support 6 as needed. A connecting component 1 and a wiring module 3 are installed on the tower-type meteorological support 6, and a lightning protection module 2 is installed on the connecting component 1. The lightning protection module 2 is connected to the wiring module 3 and the grounding structure 4 in sequence.

[0044] Furthermore, the wiring module 3 is installed on the tower-type meteorological support 6 via the cable tray 5.

[0045] Regarding the fixed installation of connection component 1:

[0046] ① In some implementations, the connecting assembly 1 includes a flange end 121, which is fixedly connected to a flange interface on the tower meteorological support 6. (The flange interface is located on the upper end face of the tower meteorological support 6.)

[0047] Achieve fixed installation of connection component 1.

[0048] ② See also Figure 1 , 2 In some implementations, the connecting assembly 1 includes a flange end 121 and a positioning clip mounted on the flange end 121. The positioning clip includes a reference plate 122, a triangular stop block, and a rubber pad 13. The two adjacent sides of the triangular stop block are respectively fixedly connected to the connecting end of the reference plate 122 and the rubber pad 13. The functional end of the reference plate 122 is connected to the flange end 121 by a fastening bolt 14. The rubber pad 13 abuts against the tower-type meteorological support 6, and the rubber pad 13 is provided with anti-slip texture.

[0049] The positioning clips are mounted in a circular array on the flange end 121. One end of the positioning clip points to the center of the flange, and the other end of the positioning clip is connected to the flange end 121 by fastening bolts 14.

[0050] The bolt hole diameter in the reference plate 122 is larger than the diameter of the fastening bolt 14 connected to it. This facilitates the swinging movement of the reference plate 122 around the fastening bolt 14.

[0051] The length of the reference plate 122 is greater than the radius of the flange end 121, and there are no fewer than three positioning clips on the flange end 121.

[0052] During the installation of connecting component 1, tightening the fastening bolts 14 causes parallel movement between the base plate 122 and the flange end 121. This continues until the rubber pad 13 comes into contact with the tower-type weather support 6, clamping and fixing the tower-type weather support 6, thus achieving the clamping and fixing of connecting component 1.

[0053] See Figure 1 , 3 The lightning protection module 2 is provided with an extension sleeve 21, a connecting sleeve 22 installed on the extension sleeve 21, a wind cup 23 fixedly installed on the connecting sleeve 22, and a lightning rod 24 sleeved and installed inside the connecting sleeve 22.

[0054] The extension sleeve 21 is fixedly mounted on the flange end 121, and a wiring opening is provided on one side of the extension sleeve 21. The extension sleeve 21 is made of ceramic.

[0055] The connecting sleeve 22 is assembled and connected to the extension sleeve 21 via ball bearings.

[0056] The wind cup 23 includes a first cutting blade 231 fixedly connected to the connecting sleeve 22 and a semi-circular spherical shell 232 fixedly connected to the first cutting blade 231. The first cutting blade 231 is horizontally arranged. The first cutting blade 231 and the semi-circular spherical shell 232 are arranged in a ring and fixedly connected to the connecting sleeve 22.

[0057] The lightning rod 24 includes a grounding main pin and supporting auxiliary pins. Multiple supporting auxiliary pins are provided and arranged in an umbrella shape and fixedly connected to the grounding main pin. The grounding main pin passes through and is disposed in the connecting sleeve 22, and the supporting auxiliary pins are disposed on the upper side of the connecting sleeve 22.

[0058] The grounding main pin and the connecting sleeve 22 rotate in coordination.

[0059] The angle between the supporting auxiliary pin and the grounding main pin is 30-60 degrees. At least six supporting auxiliary pins are provided. This improves the ability to capture fallen threads and plastic bags.

[0060] When there is wind, the wind cup 23 rotates. This drives the first cutting blade 231 to separate and cut the wire and plastic bag that are wrapped around the lightning rod 24 at one end and connected to the structure at the other end.

[0061] To avoid lightning strikes where the energy of the lightning is conducted along the winding path, damaging other structures or facilities.

[0062] In some embodiments, a second sleeve 25 is fitted between the connecting sleeve 22 and the ball bearing. A first gear 233 is fitted at the lower end of the connecting sleeve 22, and a second gear 252 is fitted at the lower end of the second sleeve 25. The first gear 233 is connected to the second gear 252 through a reduction gear set 26. The reduction gear set 26 is installed inside the extension sleeve. The upper end face of the second sleeve 25 is convenient for setting a second cutting blade 251. The second cutting blade 251 is lower than the height of the wind cup 23.

[0063] The reduction gear set 26 has a linear velocity conversion ratio of 20:1 for the first gear 233 and the second gear 252.

[0064] For some tougher threads, a method of slowing down and increasing the force is used to perform the cutting operation, thereby increasing the magnitude of the force applied during the cutting process.

[0065] When the wind cup is at a wind speed of ≥5m / s, it drives the first cutting blade to rotate. The speed is reduced to 1 / 20 of the original speed through the reduction gear set, so that the second cutting blade generates greater torque and effectively cuts tough materials.

[0066] See Figure 1 , 4 The wiring module 3 is provided with a connecting wire 31, and a ceramic sleeve 32, a rubber tube 33 and a protective shell 34 are sequentially sleeved on the outside of the connecting wire 31.

[0067] The rubber hose is made of EPDM (ethylene propylene diene monomer rubber), with a thickness of 5cm and a pressure resistance rating of ≥10kV, taking into account both insulation and flexibility.

[0068] The wiring module 3 is installed on the tower meteorological support 6 via the cable tray 5; the cable tray 5 includes a connecting beam, and clamps are set at both ends of the connecting beam, and the clamps are fixedly connected to the tower meteorological support 6 and the protective shell 34 respectively.

[0069] Among them, the combination Figure 3 The connecting wire 31 passes through the wiring opening and is fixedly abutted against the grounding main pin.

[0070] The upper end face of the ceramic sleeve 32 is higher than the flange end 121, the thickness of the rubber tube 33 is not less than five centimeters, and a beam plate 35 is fixedly installed on the outer side of the lower end face of the protective shell 34.

[0071] See Figure 1 , 5 The grounding structure 4 includes a concrete base 41, a reinforcing cage 42 disposed in the concrete base 41, and base bolts 43 disposed on the concrete base 41. The lower end face of the reinforcing cage 42 extends more than 0.5 meters beyond the lower end face of the concrete base 41.

[0072] According to the "Code for Design of Lightning Protection of Buildings" (GB 50057-2010), the burial depth of the grounding electrode must be ≥0.5m. In this design, the reinforcing cage extends more than 0.5 meters, and combined with an ion-releasing agent, the grounding resistance can be reduced to below 10Ω.

[0073] One end of the reinforcing cage 42 and the base bolt 43 is fixedly installed inside the concrete base 41. The tower-type meteorological support 6 is fixedly installed on the base bolt 43.

[0074] Among them, the combination Figure 4 The beam plate 35 is fixedly connected to the base bolt 43. The ceramic sleeve 32 and the rubber tube 33 penetrate the concrete base 41. The lower end of the ceramic sleeve 32 and the rubber tube 33 is more than 0.2 meters above the ground. The connecting wire 31 is tied to the reinforcing cage 42. The periphery of the reinforcing cage 42 is filled with ion-releasing agent and drag-reducing agent.

[0075] The reinforcing bar is welded and fixedly connected to the base bolt 43.

[0076] When lightning strikes, the lightning strike energy is conducted into the ground via the lightning rod 24 and the connecting wire 31, thus protecting the device.

[0077] Simultaneously, the design incorporating a steel cage (42mm) and a slow-release agent further enhances the ground discharge efficiency. The filling with the ion-release agent reduces soil resistivity and improves grounding efficiency.
