[0002] In photovoltaic power plants, module-side grounding is a crucial step, as it not only relates to the safe operation of the power plant but also directly affects the stability of the power generation system.

[0003] To reduce the grounding resistance of the grounding strip, some manufacturers wrap the grounding strip with graphite-based flexible resistance-reducing cloth and fix the cloth with multiple metal clamps.

[0004] However, existing metal clamps usually need to be customized according to the thickness of the composite of the resistance-reducing cloth and the grounding strip. When the composite thickness is different, the corresponding clamp needs to be replaced, which is inconvenient in use. Utility Model Content

[0024] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-2 As shown in the figure, this embodiment discloses a composite device of graphite-based flexible resistance-reducing cloth and grounding strip for photovoltaic power stations, including two clamping bodies 1 that can be opened and closed. One clamping body 1 is provided with a clamping groove 101, and the other clamping body 1 is provided with a clamping groove 102 corresponding to the clamping groove 101. A pressing plate 2 is slidably connected in the clamping groove 102. The pressing plate 2 is connected to an adjustment mechanism 3, and the adjustment mechanism 3 is connected to the corresponding clamping body 1.

[0026] In this embodiment, the composite 4 formed by wrapping the graphite-based flexible resistance-reducing cloth around the grounding strip is placed in the clamping groove 101, and then another clamping body 1 is connected; after connection, under the action of the adjustment mechanism 3, the pressing plate 2 can be tightly pressed against the composite 4.

[0027] By adopting this solution, the adjustment mechanism 3 and the clamping plate 2 can be used to clamp and fix composites 4 of different thicknesses, thus solving the problem of inconvenience in using existing metal clamps when dealing with composites 4 of different thicknesses.

[0028] Further optimize the plan, such as Figure 3 As shown, the adjustment mechanism 3 includes multiple elastic telescopic components 31. One end of the elastic telescopic component 31 is connected to the pressure plate 2, and the other end is connected to the groove wall of the clamping groove 102.

[0029] In this embodiment, when the two clamping bodies 1 are connected, the elastic telescopic component 31 is in a compressed state and can generate a rebound force. Under the action of this rebound force, the clamping plate 2 can be pressed tightly against the composite body 4.

[0030] As an optional embodiment, such as Figure 4As shown, the adjusting mechanism 3 may also include a vertically arranged adjusting screw 32. The bottom of the adjusting screw 32 extends into the clamping groove 102 and is rotatably connected to the pressure plate 2. The top of the adjusting screw 32 extends to the outside of the clamping groove 102 and is fixedly connected to a knob 33. The adjusting screw 32 is threadedly connected to the corresponding clamping body 1. A locking nut 34 is threadedly connected to the adjusting screw 32 and abuts against the corresponding clamping body 1. By rotating the knob 33, the adjusting screw 32 is driven to rotate. Under the action of the adjusting screw 32, the pressure plate 2 can be driven to move up and down in the vertical direction, thereby pressing the composite 4. After pressing, by rotating the locking nut 34, it is tightly pressed against the surface of the clamping body 1, which can lock the adjusting screw 32 and prevent the adjusting screw 32 from rotating.

[0031] Further optimize the plan, such as Figure 3 , Figure 5 As shown, the elastic telescopic component 31 includes a telescopic rod 311, one end of which is connected to the pressure plate 2, and the other end is connected to the groove wall of the clamping groove 102; a spring 312 is sleeved on the outer periphery of the telescopic rod 311, and the two ends of the spring 312 are respectively connected to the pressure plate 2 and the groove wall of the clamping groove 102.

[0032] In this embodiment, the telescopic rod 311 is arranged vertically, with its telescopic end fixedly connected to the pressure plate 2 and its fixed end fixedly connected to the groove wall of the clamping groove 102. The telescopic rod 311 can only extend and retract within a certain range. The two ends of the spring 312 abut against the pressure plate 2 and the groove wall of the clamping groove 102, respectively. By cooperating with the telescopic rod 311 and the spring 312, the pressure plate 2 can press and fix the composite body 4 of different thicknesses.

[0033] Further optimize the plan, such as Figure 5 As shown, the telescopic rod 311 includes a mounting sleeve 3111, in which a rod body 3112 is slidably connected. A limit block 3113 is provided at one end of the rod body 3112 located in the mounting sleeve 3111, and the rod body 3112 is limited to the mounting sleeve 3111 by the limit block 3113.

[0034] In this embodiment, the top surface of the mounting sleeve 3111 is fixedly connected to the groove wall of the clamping groove 102, and the bottom surface of the rod 3112 is fixedly connected to the top surface of the clamping plate 2; the limiting block 3113 is located inside the mounting sleeve 3111 and is fixedly connected to the top of the rod 3112; the limiting block 3113 can prevent the rod 3112 from coming out of the mounting sleeve 3111.

[0035] Further optimize the plan, such as Figure 3As shown, guide grooves 1020 are provided on both sides of the clamping groove 2 102, and both ends of the clamping plate 2 extend into the corresponding guide grooves 1020 and slide therein. Through the guide grooves 1020, the clamping plate 2 can only move in the direction of approaching or moving away from the composite 4.

[0036] Further optimize the plan, such as Figure 2 , Figure 3 As shown, both sides of the two clamping bodies 1 are provided with connecting plates 103, and the connecting plates 103 located on the same side are detachably connected by connecting components.

[0037] In this embodiment, the connecting plate 103 is fixedly connected to the side wall of the clamping body 1. When the two clamping bodies 1 are connected, the connecting plates 103 on the same side are in contact with each other. The connecting component 1 can be set as multiple connecting bolts and nuts, and the connecting plates 103 on the same side are detachably connected by bolt connection. In this method, the two clamping bodies 1 are split structures.

[0038] As an optional embodiment, such as Figure 6 As shown, it is also possible that one side of the two clamping bodies 1 is hinged together by multiple hinges, and the other side is fixedly connected with a connecting plate 2 104. The two connecting plates 2 104 are detachably connected by a connecting component 2. When connected, the two connecting plates 2 104 are in contact with each other. The connecting component 2 can be set as multiple connecting bolts and nuts, and the two connecting plates 2 104 on this side are detachably connected by bolt connection.
