Description

Technical Field

[0001] This utility model belongs to the technical field of surge arrester counters, specifically relating to a surge arrester counter that is easy to install. Background Technology

[0002] In modern power systems, surge arresters are key devices that protect electrical equipment from damage caused by lightning overvoltage and switching overvoltage. Surge arrester counters, as important supporting equipment for recording the number of surge arrester operations, directly affect the safety monitoring and stable operation of the power system in terms of their performance and installation reliability.

[0003] Currently, traditional surge arrester counters face numerous problems during installation. Most methods involve bolting the counter to utility poles or other supporting structures. This installation method requires workers to carry multiple tools such as wrenches and screwdrivers, and involves tightening bolts at different locations multiple times. The process is cumbersome, and for high-altitude operations, it is not only time-consuming and labor-intensive but also poses significant safety risks, severely impacting the efficiency of power engineering construction. Statistics show that counter failures caused by loose bolts account for over 30%. Therefore, those skilled in the art have proposed an easy-to-install surge arrester counter to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a surge arrester counter with a simple structure and reasonable design that is easy to install in order to solve the above problems.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a back plate, two connecting plates, and a quick-locking assembly. The quick-locking assembly includes first locking blocks installed at the upper and lower ends of the rear sidewall of the back plate. The quick-locking assembly also includes second locking blocks respectively installed on the front sidewalls of the two connecting plates. The two second locking blocks and the two first locking blocks are staggered. The upper second locking block is engaged with the upper first locking block, and the lower second locking block is engaged with the lower first locking block. A counter body is installed on the front sidewall of the back plate, and a clamp is installed on the rear sidewall of each of the two connecting plates.

[0006] As a further optimization of this utility model, the top of the first locking block at the upper end and the top of the second locking block at the upper end, as well as the bottom of the first locking block at the lower end and the bottom of the second locking block, are each provided with a through groove that is connected to each other. The two through grooves are symmetrically distributed, and the two through grooves located inside the first locking block are fixedly fitted with limit sleeves.

[0007] As a further optimization of this utility model, the top and bottom of the two through slots and the inner walls of the two limiting sleeves are respectively connected by torsion bars, and the top and bottom of the outer walls of the two torsion bars are respectively fixedly sleeved with torsion-tension composite springs.

[0008] As a further optimization of this utility model, the top and bottom of the two torsion bars are respectively fixedly installed with operating knobs movably connected to the top of the corresponding first locking block, one end of the two torsion-tension composite springs is respectively fixedly connected to the bottom and top of the corresponding operating knobs, and the other end of the two torsion-tension composite springs is respectively fixedly connected to the top and bottom of the inner wall of the corresponding limiting sleeve.

[0009] As a further optimization of this utility model, incomplete toothed discs are respectively installed at the top and bottom of the two torsion bars, and incomplete toothed rings are respectively installed at the lower and upper positions of the inner sidewalls of the two through grooves, and the two incomplete toothed discs respectively mesh with the tooth ends of the corresponding incomplete toothed rings.

[0010] As a further optimization of this utility model, protective side plates for protecting the counter body are installed on both sides of the back plate.

[0011] As a further optimization of this utility model, shock absorbers are fixedly installed at the four corners of the rear side wall of the back plate, and the rear side walls of the four shock absorbers are respectively engaged with the front side walls of the two corresponding connecting plates.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model adopts a unique quick-locking component. By rotating the operating knob, the meshing transmission of the incomplete gear disc and the incomplete gear ring, combined with the elastic force of the torsion-tension composite spring, can realize the quick connection and separation of the back plate and the connecting plate. The entire installation process does not require complicated tools, which greatly reduces labor and time costs.

[0014] 2. This utility model is equipped with a protective side plate, which can effectively block collisions with external objects and rainwater erosion; the shock absorber adopts a composite structure of damping rod and spring, which can absorb external vibrations in real time and reduce the damage of vibrations to the precision components inside the counter body.

[0015] 3. The locking structure of the quick-locking component of this utility model can generate a strong locking force after installation, which, together with the clamp, firmly secures the supporting structure such as the utility pole. Attached Figure Description

Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] like Figures 1-5As shown, an easy-to-install surge arrester counter comprises a counter body 1, a back plate 2, protective side plates 3, a quick-locking assembly 4, a shock absorber 5, a connecting plate 6, and a clamp 7. The counter body 1 records the number of surge arrester actions. The back plate 2 serves as the basic load-bearing component, used to mount the counter body 1 and connect it to the quick-locking assembly 4. The protective side plates 3 protect the counter body 1. The quick-locking assembly 4 enables quick connection between the counter and the installation position. The shock absorber 5 enhances the stability of the connection. The connecting plate 6 and the clamp 7 are used to fix the counter to a supporting structure such as a utility pole. The counter body 1 is fixed to the front side wall of the back plate 2 with screws, ensuring that the counter body 1 is firmly connected to the back plate 2 so that it can work normally during subsequent installation and use and accurately record the number of surge arrester actions. The two side walls of the back plate 2 are respectively installed with protective side plates 3 by welding. The two protective side plates 3 and the back plate 2 together form a semi-enclosed structure, which encloses the counter body 1, effectively preventing damage to the counter body 1 from external object collisions, rainwater erosion, etc., and improving the protective performance of the counter.

[0027] like Figures 1-7As shown, the quick-locking assembly 4 has two first locking blocks 403, which are welded and fixed to the upper and lower ends of the rear sidewall of the back plate 2, respectively. Similarly, there are two second locking blocks 402, which are welded to the front sidewalls of the two connecting plates 6. The two second locking blocks 402 and the two first locking blocks 403 are staggered. During installation, the upper second locking block 402 engages with the upper first locking block 403, and the lower second locking block 402 engages with the lower first locking block 403, thus initially achieving the locking of the back plate. 2. The connection with the connecting plate 6 is achieved by providing interconnected through slots 404 at the top of the upper first locking block 403 and the bottom of the lower first locking block 403 and the second locking block 402, which are already engaged. The two through slots 404 are symmetrically distributed and located within the through slot 404 inside the first locking block 403. A limiting sleeve 405 is fixedly installed by interference fit. The limiting sleeve 405 is made of high-strength plastic and has a smooth inner wall, providing stable guidance and limiting for the subsequent rotation of the torsion bar 407. Two through slots 404 are connected to the top and bottom of the two through slots 404 and the inner walls of the two limiting sleeves 405, respectively. Torsion springs 406 are fixedly fitted onto the top and bottom of the outer walls of the torsion springs 407. One end of the torsion spring 406 is welded to the bottom and top of the corresponding operating knob 401, and the other end is welded to the top and bottom of the inner wall of the corresponding limiting sleeve 405. When the operating knob 401 is rotated, the torsion springs 407 rotate accordingly, and the torsion springs 406 elastically deform. The two torsion rods 407 are connected by keys to install incomplete gear discs 409 at their top and bottom. At the same time, incomplete gear rings 408 are fixedly installed by screws at the lower and upper ends of the inner sidewalls of the two through slots 404. The two incomplete gear discs 409 mesh with the tooth ends of the corresponding incomplete gear rings 408. When the torsion rods 407 are rotated, the incomplete gear discs 409 and incomplete gear rings 408 mesh with each other to achieve the locking and unlocking functions of the quick locking component 4.

[0028] like Figures 1-4 As shown, shock absorbers 5 are fixedly installed at the four corners of the rear side wall of the back plate 2 with screws. The shock absorbers 5 adopt a composite structure of damping rod and spring, which has good shock absorption performance. The rear side walls of the four shock absorbers 5 are respectively engaged with the front side walls of the two corresponding connecting plates 6 through the cooperation of slots and blocks. After the counter is installed, the shock absorbers 5 can effectively absorb external vibrations, reduce the impact of vibration on the counter body 1, and improve the stability of the counter operation.

[0029] like Figures 1-3As shown, the rear sidewalls of the two connecting plates 6 are each fitted with a clamp 7 by welding. The clamp 7 has an adjustable structure and consists of two semicircular rings and fastening bolts. During installation, the clamp 7 is wrapped around the supporting structure such as the utility pole. By tightening the fastening bolts, the clamp 7 can be firmly fixed to the supporting structure, thereby securing the entire counter in the designated position.

[0030] It should be noted that when using this utility model: First, wrap the clamps 7 on the two connecting plates 6 around the appropriate positions on the utility pole, and tighten the fastening bolts on the clamps 7 to firmly fix the clamps 7 to the utility pole, completing the initial fixation of the connecting plate 6 and the utility pole. Next, align the first locking block 403 on the back plate 2 with the second locking block 402 on the connecting plate 6, so that the upper second locking block 402 is aligned with the upper first locking block 403, and the lower second locking block 402 is aligned with the lower... The first locking block 403 at each end is engaged. Then, the two operating knobs 401 are rotated simultaneously. The operating knobs 401 drive the torsion bar 407 to rotate. The incomplete gear disc 409 and the incomplete gear ring 408 on the torsion bar 407 mesh and rotate with each other. As the torsion bar 407 rotates, the torsion-tension composite spring 406 deforms and generates a locking force, so that the first locking block 403 and the second locking block 402 are tightly connected, completing the installation of the counter. The whole process does not require complicated tools and is simple and quick to operate.

[0031] Usage process:

[0032] After the counter is put into use, the protective side plate 3 continuously protects the counter body 1, blocking external debris from collision and rainwater intrusion; the shock absorber 5 absorbs the vibration caused by wind, equipment operation, etc. in real time, avoiding damage to the precision components inside the counter body 1, and ensuring that the counter body 1 can accurately record the number of times the surge arrester operates.

[0033] Disassembly process:

[0034] When the counter needs to be repaired or replaced, turn the operating knob 401 in the opposite direction to disengage the incomplete gear disc 409 from the incomplete gear ring 408. The torsion-tension composite spring 406 returns to its original state, releasing the locking force between the first locking block 403 and the second locking block 402. At this time, the back plate 2 can be easily separated from the connecting plate 6. Then, loosen the fastening bolts on the clamp 7 to remove the entire counter from the utility pole. The disassembly process is equally simple and efficient.

[0035] The above-described embodiments are merely examples of several implementations of this utility model. The descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
