Description

Technical Field

[0001] This application relates to lightning protection testing, and more particularly to a lightning protection testing device. Background Technology

[0002] Lightning protection testing is a key measure to protect buildings and their internal equipment from lightning disasters. Its core lies in constructing a complete lightning protection grounding system to prevent the hazards of overvoltage, overcurrent, and electromagnetic pulses caused by lightning. As an important type of lightning arrester in the lightning protection grounding system, lightning arrester strips are usually laid horizontally or inclined. They can be installed openly or concealed under the concrete or tiles of the roof. They are connected to the down conductor at least at both ends. The protection range of the building needs to be calculated and determined according to the rolling sphere method. It is the core component for realizing direct lightning protection of buildings and is widely used in lightning protection projects of various civil and industrial buildings.

[0003] In the prior art, utility model patent CN216134257U discloses a lightning protection detection lightning strip device, including a fixed plate, an adjusting plate, and a base plate. The upper surface of the base plate has mounting holes, and two mounting plates are symmetrically distributed on the upper surface of the base plate, each with threaded holes. The adjusting plate is installed between the two mounting plates and has holes. Fastening bolts are threaded onto the mounting plates, and limit plates are provided on the outer surface of the fastening bolts. The fastening bolts pass through the adjusting plates, and the limit plates are in contact with and fixed to the adjusting plates. A sleeve rod is installed at the upper end of the adjusting plate, and a telescopic rod is sleeved inside the sleeve rod. The fixed plate is welded to the end of the telescopic rod. The fixing plate has fixing holes, and U-shaped clamps are inserted into the fixing holes. This utility model has the advantages of being able to adjust the height and angle of the lightning protection strip, and can more effectively protect the building. However, it has the problem of limited protection range. The above-mentioned prior art still has significant shortcomings. Its lightning protection strip fixing structure has poor dimensional adaptability. The U-shaped clamp used to fix the lightning protection strip and the fixing holes on the fixing plate are designed for fixed size adaptation, which can only fix lightning protection strips of a single specification. When lightning protection construction requires the replacement of lightning protection strips of different sizes, the corresponding U-shaped clamps or fixing plates must be replaced at the same time. This not only increases the construction cost and the difficulty of spare parts management, but also fails to meet the adaptation needs of diverse specifications of lightning protection strips, thus limiting its versatility and practicality.

[0004] To address the shortcomings of the aforementioned prior art, this application proposes a lightning protection detection lightning strip device that can accommodate lightning strips of different sizes, thereby improving the device's practicality and versatility. Utility Model Content

[0005] The purpose of this application is to provide a lightning protection detection lightning strip device, which has advantages such as good practicality and solves the problem that it can only fix lightning strips of a single specification.

[0006] The lightning protection detection lightning strip device provided in this application adopts the following technical solution: it includes a frame and two sets of extension components and a support component.

The top of the frame is provided with a sliding rod and a bidirectional lead screw near both sides. The surface of the bidirectional lead screw is threaded with two sets of threaded blocks, and the shaft end of the bidirectional lead screw is provided with a knob.

[0007] By adopting the above technical solution, the combination design of the top slide bar and the bidirectional lead screw, together with the threaded block on the surface of the bidirectional lead screw and the knob at the shaft end, can drive the threaded block to move along the bidirectional lead screw by rotating the knob, thereby adjusting the position of the two sets of arc plates, which can be applied to lightning protection belts of different diameters.

[0008] Preferably, the surface of the slide rod is slidably connected to two sets of sliding plates, and the top of both sets of sliding plates and the two sets of threaded blocks are provided with arc-shaped plates, and a connecting rod is provided between the two sets of sliding plates and the two sets of threaded blocks.

[0009] By adopting the above technical solution, the connecting rod between the slide and the threaded block can ensure that the two move synchronously, avoiding misalignment during the adjustment process. Combined with the guiding effect of the slide rod on the slide, the movement of the threaded block and the slide is more stable.

[0010] Preferably, the top of the frame is provided with a sliding groove, and two sets of sliders are slidably connected in the sliding groove. The two sets of sliders are respectively fixedly connected to the bottom of two sets of threaded blocks.

[0011] By adopting the above technical solution, the sliding cooperation between the groove and the bottom slider of the threaded block can accurately guide the movement direction of the threaded block, prevent the threaded block from rotating synchronously with the screw during the bidirectional screw rotation, and ensure that the threaded block moves smoothly only along the screw axis.

[0013] By adopting the above technical solution, and using a hinged connection between two sets of movable plates, it is easy to store and open the movable plates. The spring and clamping plate form an elastic clamping structure. The elastic force of the spring can drive the clamping plate to adaptively fit lightning protection tapes of different diameters or thicknesses. The extension frame can be slid to different positions to accommodate lightning protection tapes of different lengths. Preferably, the frame has through slots on both sides and a groove at the bottom of the inner wall of the frame, and the connecting block is slidably connected in the groove.

[0014] By adopting the above technical solution, the sliding action of the connecting block in the groove can prevent the extension frame from getting stuck during the sliding process, making the sliding smoother.

[0015] Preferably, the through groove is adapted to the card hole, a card rod is engaged in the card hole and the through groove, and connecting straps are fixedly connected to both sides of the frame, the connecting straps being made of rubber.

[0016] By adopting the above technical solution, the locking rod that engages with the slot and the locking hole can quickly fix the extension component to the frame, making it easy to fix the extension frame. By setting the connecting strap, it is easy to pull out manually.

[0017] Preferably, a protective groove is provided on one side of the frame, the knob is located in the protective groove, and a protective cover is movably connected to the surface of the protective groove via a hinge.

[0018] By adopting the above technical solution, the protective groove houses the knob, and together with the protective cover connected by the hinge, it can effectively prevent the adjusted threaded block from shifting due to accidental contact with the knob during daily use, thus ensuring the stability of the lightning protection belt's fixed state.

[0019] Preferably, the support assembly includes a base plate, and damping shock absorbers are fixedly connected to the top of the base plate near both sides. A connecting plate is provided on the top of the damping shock absorber, and two sets of threaded holes are opened on the top of the base plate.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0025] Example 1: A lightning protection detection device, referring to... Figure 1 and Figure 3 The system includes a frame 1, two sets of extension components 3, and a support component 2. Its features include: the two sets of extension components 3 are slidably connected within the frame 1; the support component 2 is located at the bottom of the frame 1; a slide rod 101 and a bidirectional lead screw 105 are respectively located near the sides of the top of the frame 1; two sets of threaded blocks 109 are threaded onto the surface of the bidirectional lead screw 105; and a knob 107 is located at the shaft end of the bidirectional lead screw 105. The combination of the slide rod 101 and the bidirectional lead screw 105 at the top of the frame 1, along with the threaded blocks 109 on the surface of the bidirectional lead screw 105 and the knob 107 at the shaft end, allows the rotation of the knob 107 to drive the threaded blocks 109 to move along the bidirectional lead screw 105, adjusting the position of the two sets of arc plates 110, thus adapting to lightning protection belts of different diameters.

[0026] Example 2: A lightning protection detection device, referring to... Figure 1 , Figure 3 and Figure 6Two sets of sliding plates 102 are slidably connected to the surface of the slide rod 101. Both sets of sliding plates 102 and the tops of the two sets of threaded blocks 109 are provided with arc-shaped plates 110. A connecting rod 111 is provided between the two sets of sliding plates 102 and the two sets of threaded blocks 109. The connecting rod 111 between the sliding plates 102 and the threaded blocks 109 ensures that they move synchronously, avoiding misalignment during adjustment. Combined with the guiding effect of the slide rod 101 on the sliding plates 102, the movement of the threaded blocks 109 and the sliding plates 102 is more stable. A groove 113 is provided at the top of the frame 1. Two sets of sliders 112 are slidably connected within the groove 113. The two sets of sliders 112 are respectively fixedly connected to the bottoms of the two sets of threaded blocks 109. The sliding cooperation between the groove 113 and the bottom sliders 112 of the threaded blocks 109 can accurately guide the movement direction of the threaded blocks 109, preventing the threaded blocks 109 from moving with the screw during the rotation of the bidirectional lead screw 105. The rod rotates synchronously, ensuring that the threaded block 109 moves smoothly only along the screw axis. The extension assembly 3 includes an extension frame 301. The top of the extension frame 301 is movably connected to two sets of movable plates 302 via hinges. The top of each set of movable plates 302 is provided with two sets of support plates 303. Multiple sets of springs 304 are provided inside each set of support plates 303. A clamping plate 305 is provided at the other end of the spring 304. A connecting block 306 is provided at the bottom of the extension frame 301. Multiple sets of locking holes 307 are opened on the surface of the connecting block 306. The two sets of movable plates 302 are connected by hinges, which makes it easy to store and open the movable plates 302. The springs 304 and the clamping plates 305 form an elastic clamping structure. The elastic force of the springs 304 can drive the clamping plates 305 to adaptively fit the lightning protection tape of different diameters or thicknesses. The extension frame 301 can be slid to different positions, which is suitable for lightning protection tape of different lengths.

[0027] Example 3: A lightning protection detection device, referring to... Figure 1 , Figure 5 and Figure 6Both sides of the frame 1 have through slots 103, and the bottom of the inner wall of the frame 1 has a groove 104. The connecting block 306 is slidably connected in the groove 104. With the sliding action of the connecting block 306 in the groove 104, the extension frame 301 can be prevented from getting stuck during sliding, making the sliding smoother. The through slot 103 is adapted to the locking hole 307. The locking hole 307 and the through slot 103 are engaged with the locking rod 308. Both sides of the frame 1 are fixedly connected with connecting straps 309. The connecting straps 309 are made of rubber. The locking rods 308 engaged in the through slot 103 and the locking hole 307 can quickly fix the extension component 3 to the frame 1, which is convenient for fixing the extension frame 301. The connecting straps 309 make it easy to pull out manually. One side of the frame 1 has a protective groove 108. The knob 107 is located inside the protective groove 108. The surface of the protective groove 108 is movably connected to the protective cover 106 via a hinge. The protective groove 108 houses the knob 107. The protective cover 106 connected by the hinge can effectively prevent the adjusted threaded block 109 from shifting due to accidental contact with the knob 107 during daily use, ensuring the stability of the lightning protection strip's fixed state. The support component 2 includes a base plate 201. Damping shock absorbers 203 are fixedly connected to the top of the base plate 201 near both sides. A connecting plate 204 is provided on the top of the damping shock absorber 203. Two sets of threaded holes 202 are opened on the top of the base plate 201. The damping shock absorber 203 on the top of the base plate 201 can buffer external vibration impacts, such as strong winds and collisions during installation, to prevent the lightning protection strip from loosening or fatigue damage due to long-term vibration.

[0028] The implementation principle of this application embodiment is as follows: When using the lightning protection detection lightning strip device, the installation position of the device must first be determined according to the lightning protection installation requirements of the building roof. Then, the base plate 201 of the support component 2 is fixedly connected to the preset installation point on the roof through the threaded hole 202 at its top. The damping shock absorber 203 at the top of the base plate 201 can buffer the installation collision force during the fixing process, and at the same time avoid the device from shifting or the lightning strip from loosening due to external vibration during long-term use. After the support component 2 is fixed, the coverage range of the device is adjusted according to the actual length of the lightning strip to be installed. The rubber connecting strips 309 on both sides of the frame 1 are pulled, the clamping rod 308 is taken out and pulled out from the through groove 103 and the clamping hole 307. The extension frame 301 is pulled so that the connecting block 306 at the bottom slides smoothly along the groove 104 on the inner wall of the frame 1 until the length of the two sets of extension frames 301 combined with the frame 1 matches the length of the lightning strip. Then the clamping rod 308 is re-clamped in. The extension component 3 is fixed in the corresponding slot 103 and the card hole 307. The movable plate 302 at the top of the extension frame 301 is opened by hinge, and the lightning-catching belt is placed on the top of the frame 1 and the arc plate 110 in the extension frame 301. After closing the movable plate 302, the protective cover 106 of the protective groove 108 on one side of the frame 1 is opened. The knob 107 in the rotating groove drives the bidirectional lead screw 105 to rotate. Since the slider 112 at the bottom of the threaded block 109 is limited and guided in the groove 113, and the slide plate 102 is synchronously connected to the threaded block 109 through the connecting rod 111, when the bidirectional lead screw 105 rotates, it will drive the two sets of threaded blocks 109 and slide plate 102 to approach the lightning-catching belt along the lead screw axis, so that the arc plate 110 gradually fits the surface of the lightning-catching belt and forms a preliminary clamping. At the same time, the spring 304 in the support plate 303 in the extension frame 301 will adaptively generate elastic force to push the clamping plate 305 to tightly fit the outer surface of the lightning-catching belt.
