Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic power plant operation and maintenance equipment technology, specifically to a photovoltaic power plant surge protector disassembly tool. Background Technology
[0002] Photovoltaic surge protectors, also known as photovoltaic surge protectors, are key devices in solar power generation systems that protect against induced lightning strikes, direct lightning strikes, or other transient overvoltage surges. They protect photovoltaic modules, inverters, and other electrical equipment from overvoltage damage caused by lightning induction or grid fluctuations. Centralized inverter photovoltaic systems include combiner boxes and DC cabinets, both of which contain photovoltaic surge protectors. These protectors are fixed to the base of the combiner box and DC cabinet using a plug-in method. During routine inspections, maintenance personnel must promptly replace any faulty surge protectors. Replacing surge protectors by hand is difficult, so tools are usually used.
[0003] Chinese utility model application No. 201922125327.2 discloses a plug-in surge arrester tool pliers, including a Y-shaped retainer for manual gripping and a caliper structure with a certain elasticity that is locked within the Y-shaped retainer for clamping and disassembling the surge arrester. The Y-shaped retainer has a pulling structure at one end connected to the caliper structure for driving the caliper structure to move relative to the Y-shaped retainer, thereby clamping and releasing the surge arrester. This utility model uses a pulling structure to move the caliper structure within the Y-shaped retainer, allowing the elastic caliper structure to clamp and release the surge arrester. This makes it easy to remove damaged surge arrester inserts from the surge arrester base without affecting the mechanical stress on the surge arrester base, achieving convenient disassembly of plug-in surge arresters and reducing manual labor. However, this utility model requires both hands to operate when disassembling the surge arrester, and the operating handle needs to be turned to remove the surge arrester, which is inconvenient to operate.

Detailed Implementation
[0028] To better understand this utility model, the following detailed description is provided in conjunction with specific embodiments.
[0029] Example 1
[0030] like Figure 1 and Figure 3 As shown, a photovoltaic power station surge protector disassembly tool includes a handle 1, a support 2, a grip 3, a connecting rod 4, and jaws 5. The handle 1 has an opening, and both ends of the opening are fixedly connected to the top surface of the support 2. The lower end of the support 2 is provided with a horizontal support foot 21. The upper end of the connecting rod 4 is fixedly connected to the grip 3, and the lower end passes through a first through hole on the top surface of the support 2 and is rotatably connected to the jaws 5. The grip 3 is located inside the area enclosed by the handle 1 and the support 2. The jaws 5 are entirely located inside the support 2. The connecting rod 4 slides up and down in the first through hole, causing the jaws 5 to clamp or release the surge protector.
[0031] like Figure 3 As shown, the jaws 5 include a first jaw 51, a second jaw 52, and a crossbar 53. Both the first jaw 51 and the second jaw 52 include an inclined rod segment and a vertical rod segment. The lower end of the inclined rod segment and the upper end of the vertical rod segment are fixedly connected. The upper end of the first jaw 51 and the upper end of the second jaw 52 are rotatably connected to the lower end of the connecting rod 4. The inclined rod segments of the first jaw 51 and the second jaw 52 are each provided with a sliding groove 54 extending along their length direction. The two ends of the crossbar 53 are slidably connected to the sliding grooves on the first jaw 51 and the second jaw 52, respectively.
[0032] Specifically, in this embodiment, it is preferred that, as follows: Figure 3 and Figure 4 As shown, the lower end of the connecting rod 4 adopts a flat design, so as to... Figure 3Based on the direction shown, the first clamp 51 and the second clamp 52 are located at the rear and front sides of the lower end of the connecting rod 4, respectively, and the upper ends of the first clamp 51 and the second clamp 52 are rotatably connected to the lower end of the connecting rod 4 via pins 6. The sliding groove 54 passes through the inclined rod section of the first clamp 51 and the inclined rod section of the second clamp 52. Sliding pins are fixedly installed at both ends of the crossbar 53, and the sliding pins are respectively installed in the sliding grooves of the first clamp 51 and the second clamp 52. It should be understood that... Figure 3 Based on the direction shown, the crossbar 53 is positioned between the first insert 51 and the second clamp 52 in the front-to-back direction. Its two ends, the sliding pins, face rearward and forward respectively, allowing them to be positioned within the sliding grooves of the first clamp 51 and the second clamp 52. To prevent the sliding pins from falling out of the sliding grooves, the portion of the sliding pin protruding from the sliding groove at the end furthest from the crossbar 53 can be slightly larger than the size of the sliding groove.
[0033] like Figure 1 and Figure 3 As shown, the handle 1, support 2, and grip 3 are all symmetrical about the line containing the connecting rod 4. The lower ends of the first clamp body 51 and the lower ends of the second clamp body 52 are provided with anti-slip textures (not shown in the attached diagram), preferably horizontally arranged. The lower ends of the first clamp body 51 and the lower ends of the support 2 adjacent to the first clamp body 51 are respectively connected to both ends of the first spring 81, and the lower ends of the second clamp body 52 and the lower ends of the support 2 adjacent to the second clamp body 52 are respectively connected to both ends of the second spring 82.
[0034] Furthermore, such as Figure 1 and Figure 3 As shown, a crossbar 22 is fixedly installed inside the support member 2 and above the jaws 5. A second through hole is provided on the crossbar 22 at a position corresponding to the first through hole. The connecting rod 4 passes through the second through hole and is rotatably connected to the jaws 5. A third spring 83 is provided between the top surface of the support member 2 and the crossbar 22, and the upper end of the third spring 83 is fixedly connected to the top surface of the support member 2. A limiting member 41 is provided on the connecting rod 4. The limiting member 41 is located between the top surface of the support member 2 and the crossbar 22, and the lower end of the third spring 73 is fixedly connected to the limiting member 41. When the limiting member 41 contacts the crossbar 22, the lower end of the jaws 5 is not lower than the lower end of the support member 2.
[0035] In this embodiment, it is further preferred that the handle 1 has a horizontal grip portion, the grip rod 3 is horizontally positioned, and the top of the support member 2 is horizontally positioned. The grip portion of the handle 1, the grip rod 3, and the portion of the connecting rod 4 near the grip rod 3 are covered with insulating material. The insulating material can be any insulating material available in the prior art, including but not limited to PVC and rubber.
[0036] When using the photovoltaic power station surge protector disassembly tool, such as the Chai Xiao photovoltaic power station surge protector, if Figure 3 and Figure 5 As shown, firstly, holding the handle 1, the horizontal support feet 21 of the support member 2 are placed against the surge protector base 9 on which the surge protector 7 is installed, so that the two horizontal support feet 21 of the support member 2 are respectively located on both sides of the surge protector 7, and the lower ends of the first clamp body 51 and the second clamp body 52 are also respectively located on both sides of the surge protector 7; then, the fingers act on the grip bar 3, applying gripping force to it. Under the action of gripping force, the grip bar 3 drives the connecting rod 4 to move upward, applying an upward force to the clamp jaws 5 through the pin 6. At the same time, the first spring 81 and the second spring 82 exert an upward force on the first clamp. Jaw 51 and jaw 52 respectively provide downward force. Under their combined action, the vertical segments of the first clamp body 51 and the second clamp body 52 move towards each other to clamp the surge protector 7. As the gripping force continues to be applied, the gripping rod 3 moves upward along with the jaws 5 via the connecting rod 4, thereby pulling the surge protector 7 clamped by the jaws 5 from the surge protector base 9. The disassembly tool is moved to a suitable position, and the gripping force on the gripping rod 3 is released. Under the combined action of the first spring 81, the second spring 82 and the third spring 83, the jaws 5 release the surge protector 7.
[0037] It should be noted that when the disassembly tool is not in use, the first spring 81, the second spring 82, and the third spring 83 are in their natural state. When a gripping force is applied to the handle 3, the first spring 81 and the second spring 82 are in a stretched state, and the third spring 83 is in a compressed state. The limiting member 41 is used to limit the vertical movement range of the connecting rod 4. During the vertical movement of the connecting rod 4, the sliding pins at both ends of the crossbar 53 slide in the sliding groove. Through the crossbar 53, the first clamp body 51 and the second clamp body 52 can be kept in a fixed relative position in the front-back direction. In order to prevent the connecting rod 4 from rotating relative to the support member 2 in the first and second through holes, the connecting rod 4 as a whole (excluding the flat design part connected to the jaws 5) can be set as a prism (such as a quadrangular prism) or an elliptical cylinder (with an elliptical cross-section). The shape of the first and second through holes matches the shape of the cross-section of the connecting rod 4.
[0038] Example 2
[0039] This embodiment is similar to the previous embodiments, except that, as Figure 6As shown, the handle 1, excluding the horizontally positioned gripping part, is more rounded. The slide groove 54 does not penetrate the inclined rod section of the first clamp body 51 or the inclined rod section of the second clamp body 52. The size of the slide groove 54 gradually increases from the inside to the outside, and the size of the sliding post, which is approximately farther away from the crossbar 53, is also larger and matches the size of the slide groove 54, thereby preventing the sliding post from falling out of the slide groove 54.
[0040] like Figure 7 As shown, the lower end of the connecting rod 4 adopts a U-shaped design, so as to... Figure 6 Based on the direction shown, the first clamp 51 and the second clamp 52 are both located inside the U-shaped opening at the lower end of the connecting rod 4, and the upper ends of the first clamp 51 and the second clamp 52 are rotatably connected to the lower end of the connecting rod 4 via a pin 6.
[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the foregoing embodiments have described this utility model in detail, those skilled in the art should understand that modifications can be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein, and these substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of this utility model.
