[0020] Specifically, please refer to Figures 1 to 3 , Figure 1 The overall structural diagram of the protection device applied to the power grounding grid provided in the embodiment of the present application is as follows: Figure 2 This is a schematic diagram of the overall cross-sectional structure of a protective device applied to a power grounding grid provided in an embodiment of the present application. Figure 3It is a schematic diagram of the cross-sectional structure of the connection between the clamp component and the grounding electrode. The protective device 100 applied to the power grounding grid includes a plurality of grounding electrodes 110 arranged in sequence. The grounding electrode 110 is existing and has nothing to do with the core invention of the present application, and will not be described here. A clamp component 120 is sleeved on the grounding electrode 110, and the clamp component 120 and the grounding electrode 110 are detachably connected. The clamp component 120 includes two semicircular arc-shaped knocking plates 121 that are knocked on both sides of the grounding electrode 110. When the two knocking plates 121 are knocked, the grounding electrode 110 will be wrapped and surrounded by the two knocking plates 121. At this time, the two knocking plates 121 can be fixed by screws or the like, so that the knocking plates 121 form a whole. A clamp 130 is connected to one side of the knocking plate 121, and a notch 131 is provided on the side of the clamp 130 away from the grounding electrode 110. The notch 131 is used to facilitate the insertion of the sliding plate 140. The two clamping plates 130 close to each other between two adjacent grounding electrodes 110 are provided with a sliding plate 140. The sliding plate 140 can slide in the slots 131 of the two clamping plates 130 according to the interval between the two grounding electrodes 110, thereby extending or shortening the length of the whole formed by the clamping plates 130 and the sliding plate 140. The two ends of the sliding plate 140 are respectively inserted into the slots 131 of the two clamping plates 130. The clamping part 120 is horizontally provided with a first reserved hole 122 for the conductor rod to pass through. The conductor rod can pass through the clamping part 120 through the first reserved hole 122. It should be noted that the first reserved hole 122 passes through the inner cavity of the clamping part 120, and the grounding electrode 110 is located in the inner cavity of the clamping part 120. During the working process, the conductor rod can be passed through the first reserved hole 122 to perform the welding work between the conductor rod and the grounding electrode 110, and then the two knocking plates 121 are knocked together. A second reserved hole 123 is provided below the first reserved hole 122. A rotating disk 124 is hinged on one side of the second reserved hole 123 on one of the knocking plates 121. A net bag 125 is wound around the rotating disk 124. The net bag 125 can be pulled out from the rotating disk 124 and supported below the sliding plate 140 and the clamping plate 130. The net bag 125 is used to support the conductor rod. A locking component 126 for locking the net bag 125 is provided on the outer periphery of the second reserved hole 123. When the net bag 125 is pulled out to a certain length, it can be locked by the locking component 126. At this time, the length of the net bag 125 will be fixed. A hook component 127 is provided on the other knocking plate 121. The hook component 127 is used to connect the free end of the net bag 125.

[0021] In the embodiment of the present application, in the specific working process, the conductor rod is first passed through the first reserved hole 122 on the two knocking plates 121 in turn, and a suitable position is selected to complete the welding between the conductor rod and the grounding electrode 110, and then the two knocking plates 121 are knocked on the outer periphery of the grounding electrode 110 and fixed, and the sliding plate 140 is stretched or retracted according to the interval between the two grounding electrodes 110 to complete the connection of the clamp component 120 on the other grounding electrode 110, and then the net bag 125 on the rotating disk 124 is pulled out, and the net bag 125 is passed through the second reserved hole 123 and fixed to the corresponding hook component 127. At this time, the bottom of the conductor rod will be supported by the net bag 125 and the top will be covered by the sliding plate 140 and the clamp 130. The rotating disk 124 is reversed to put the net bag 125 in a tensioned state, and the locking component 126 is locked at the same time.

[0022] As can be seen from the above, in the embodiment of the present application, two semicircular arc-shaped knocking plates 121 are provided to form a clamp component 120, and a clamping plate 130 is provided on the knocking plate 121, and the clamping plate 130 cooperates with the sliding plate 140, and then the present application can select the sliding length of the sliding plate 140 according to the interval between the grounding electrodes 110, so as to meet a variety of working environments, and the adjustment process is simple and convenient, and the sliding plate 140 and the clamping plate 130 cover the top of the conductor rod, which can effectively avoid the extrusion damage to the conductor rod during the later backfilling. The present application also provides components such as a net bag 125, so that the net bag 125 can be supported at the lower end of the conductor rod. When the net bag 125 is tightened, it will have a certain limiting effect on the conductor rod to ensure that the conductor rod is located below the sliding plate 140 and the clamping plate 130, avoiding extrusion damage after dislocation, and the heat dissipation effect of the net bag 125 is better, and the conductor rod can quickly achieve heat exchange by contacting with the foundation, thereby avoiding high temperature damage at the conductor rod.

[0023] In some embodiments, the locking component 126 includes a first fixing plate 126a and a second fixing plate 126b respectively disposed on the upper and lower sides of the second reserved hole 123. The top of the first fixing plate 126a is screwed with a first threaded rod 126c, and the bottom end of the first threaded rod 126c extends to the top of the second fixing plate 126b. In the embodiment of the present application, when the net bag 125 is tightened, the first threaded rod 126c can be rotated downward, and the bottom of the first threaded rod 126c will tightly press the net bag 125 on the top of the second fixing plate 126b. The friction between the net bag 125 and the first threaded rod 126c and the second fixing plate 126b will limit its displacement.

[0024] In some embodiments, a strip-shaped hole 132 is provided at the top of the clamping plate 130, and a positioning protrusion 141 is provided at the top of the sliding plate 140, and the top of the positioning protrusion 141 extends to the top of the strip-shaped hole 132. In the embodiment of the present application, through the above arrangement, during the sliding process of the sliding plate 140, the positioning protrusion 141 will slide in the strip-shaped hole 132 at the same time, thereby limiting the sliding direction of the sliding plate 140, making the sliding of the sliding plate 140 more stable.

[0025] In some embodiments, a threaded hole is provided at the top of the sliding plate 140, and the positioning protrusion 141 includes a positioning block 141a, and a second threaded rod 141b is vertically penetrated on the positioning block 141a, and the bottom of the second threaded rod 141b is screwed into the threaded hole. In the embodiment of the present application, through the above arrangement, the positioning protrusion 141 can be easily removed from the top of the sliding plate 140, so as to facilitate the installation between the sliding plate 140 and the clamping plate 130. After the sliding plate 140 and the clamping plate 130 are installed, the positioning block 141a is placed on the top of the threaded hole, and the second threaded rod 141b is penetrated through the positioning block 141a and then screwed into the threaded hole.

[0026] In some embodiments, the two sides of the knock plate 121 are respectively connected with the edge plate 128, and the two snap plates on the same grounding electrode 110 are connected by a bolt group. In the embodiment of the present application, by providing an extension plate, the two knock plates 121 are conveniently connected as one.

[0027] In some embodiments, an elastic support pad 121a is provided inside the tapping plate 121, and the elastic support pad 121a is provided close to the inner wall of the tapping plate 121. In the embodiment of the present application, by providing the elastic support pad 121a, the tapping plate 121 and the grounding electrode 110 are stably and tightly connected.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
