DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] like Figures 1 to 5 As shown, a grounding device for a distribution network grounding wire includes a grounding rod 1, a sleeve rod 2, a connecting rod 3, a grounding clamp mechanism and a discharge conductor 4. The sleeve rod 2 is fixedly arranged on the top of the grounding rod 1, the connecting rod 3 is arranged on the top of the sleeve rod 2, and the grounding clamp mechanism is arranged on the top of the connecting rod 3. The grounding rod 1, the sleeve rod 2 and the connecting rod 3 are used to support and connect the grounding clamp mechanism.

[0029] One end of the discharge wire 4 is fixedly connected to the grounding clamp mechanism, and the other end is fixedly connected to the sleeve rod 2, forming a complete discharge circuit. When discharge is required, the grounding wire is clamped by the grounding clamp mechanism, and the discharge wire 4 conducts the charge to the ground.

[0030] The grounding clamp mechanism includes a clamp seat 5, a threaded rod 31 and a clamp plate 32. The threaded rod 31 is fixedly arranged on the top of the connecting rod 3. A mounting opening 51 is provided on the clamp seat 5. A mounting hole 52 is provided at the bottom of the mounting opening 51. The threaded rod 31 is slidably matched with the mounting hole 52. The clamp plate 32 is provided on the top of the threaded rod 31. A grounding wire is placed between the top of the clamp plate 32 and the top side wall of the mounting opening 51. An avoidance opening 53 is provided on the clamp seat 5. The avoidance opening 53 is arranged below the mounting opening 51. The threaded rod 31 passes through the bottom of the clamp seat 5 and the avoidance opening 53 in sequence and extends to the mounting opening 51. A hexagonal nut 6 is provided in the avoidance opening 53, and the hexagonal nut 6 is threadedly matched with the threaded rod 31.

[0031] By rotating the hexagonal nut 6, the distance between the clamp plate 32 and the top of the installation opening 51 can be adjusted, so that the grounding wire can be firmly clamped, which can adapt to the installation requirements of grounding wires of different sizes and improve the application range of the equipment. At the same time, the discharge wire 4 connected to the clamp seat 5 and the sleeve rod 2 can be used to eliminate static electricity accumulation or release excessive current to prevent it from accumulating to a certain extent and causing discharge, which may cause harm to equipment or personnel. In the distribution network system, if the equipment fails or is struck by lightning, etc., a large current may be generated. The discharge wire 4 can release this current to the ground in time to prevent the current from damaging the equipment.

[0032] A guide rod 7 is disposed at the bottom of the clamping seat 5 , and a guide seat 71 is disposed on the outer side wall of the connecting rod 3 . The guide rod 7 is slidably matched with the mounting hole 52 on the guide seat 71 .

[0033] By slidingly cooperating with the guide rod 7 and the guide seat 71 on the outer wall of the connecting rod 3, the clamp seat 5 can be guided to move in the correct direction, avoiding deviation or shaking of the clamp seat 5 when rotating the hexagonal nut 6, effectively improving the accuracy and stability of clamping the grounding wire, and making the connection of the grounding wire more reliable.

[0034] An elastic column 33 is provided at the center of the clamping plate 32, and the bottom of the elastic column 33 is inserted into the inside of the threaded rod 31, and a spring 34 is provided inside the threaded rod 31, one end of the spring 34 is connected to the inside of the threaded column, and the other end is connected to the bottom of the elastic column 33, and the top of the elastic column 33 abuts against the grounding wire.

[0035] The bottom of the elastic column 33 is inserted into the threaded rod 31 and connected to the threaded rod 31 through the spring 34. When the hexagonal nut 6 is rotated, the elastic force of the spring 34 can make the clamping plate 32 clamp the grounding wire more tightly, thereby enhancing the clamping force of the clamping plate 32 and making it difficult for the grounding wire to fall off when subjected to external force; at the same time, the setting of the elastic column 33 also increases the flexibility of the clamping plate 32, thereby avoiding damage to the grounding wire during the clamping process.

[0036] The top of the installation opening 51 is provided with a receiving groove 54, and a grounding wire is placed in the receiving groove 54. This makes the grounding wire more stable and smooth during the clamping process, improves the installation efficiency of the grounding wire, and makes the connection of the grounding wire more convenient and quick.

[0037] The clamp seat 5 is provided with a discharge port 55, which is arranged on one side of the avoidance port 53. One end of the discharge wire 4 is inserted into the discharge port 55, and the other end is inserted into the sleeve rod 2. A positioning hole 56 is provided at the bottom of the discharge port 55. A positioning bolt 57 is provided in the positioning hole 56. The positioning bolt 57 is threadedly connected with the positioning hole 56. The positioning bolt 57 is inserted into the port of the discharge wire 4. A fixing bolt 21 is provided on the sleeve rod 2. The fixing bolt 21 fixes the other end of the discharge wire 4.

[0038] By setting a positioning bolt 57 and threading the positioning hole 56, it is ensured that the end of the discharge wire 4 can be firmly fixed in the discharge port 55; at the same time, a fixing bolt 21 is provided on the sleeve rod 2 to fix the other end of the discharge wire 4; when discharge is required, the current is conducted from one end to the other end through the discharge wire 4; the fixation of the discharge wire 4 in the discharge port 55 and the sleeve rod 2 ensures the stability and reliability of current conduction; and prevents it from loosening or falling off during use.

[0039] A support plate 58 is rotatably provided on the positioning bolt 57, and the support plate 58 abuts against the outer peripheral wall of the port of the discharge wire 4. Slide grooves 551 are provided on both sides of the discharge port 55, and sliders 581 are provided on both sides of the support plate 58, and the sliders 581 are slidably matched with the slide grooves 551.

[0040] By providing the support plate 58, when the discharge wire 4 is subjected to external force, the support plate 58 can play a supporting and fixing role, thereby enhancing the stability and reliability of the discharge wire 4 and preventing the discharge wire 4 from falling off or being damaged when subjected to external force; at the same time, the sliding block 581 and the slide groove 551 can slide together to guide the support plate 58 to move in the correct direction, so that the support plate 58 is more closely abutted against the outer peripheral wall of the port of the discharge wire 4; thus, the installation efficiency and accuracy of the support plate 58 are improved, and the connection of the discharge wire 4 is more firm and reliable.

[0041] A cylindrical groove 552 is formed at the top of the discharge port 55 . The size of the cylindrical groove 552 matches the port of the discharge wire 4 , so that the discharge wire 4 can be inserted into the discharge port 55 more smoothly, thereby preventing the discharge wire 4 from deflecting or shaking during the insertion process.

[0042] Grabbing blocks 41 are symmetrically arranged on the peripheral wall of the port of the discharge wire 4 , which are convenient for the staff to operate and fix when installing and removing the discharge wire 4 .

[0043] The bottom of the grounding rod 1 is provided with a conical column 11, and the top of the conical column 11 is provided with a limiting ring 12. The conical column 11 can be inserted into the soil more easily, increasing the contact area and stability between the grounding rod 1 and the soil; the limiting ring can limit the depth of the conical column 11 inserted into the soil, avoiding the conical column 11 being inserted too deeply, resulting in an unstable connection between the grounding rod 1 and the soil.

[0044] Working principle of the present invention: The grounding rod 1 serves as the foundation of the entire device. Through the design of the conical column 11 at the bottom, it can be easily and firmly inserted into the soil to form a good grounding channel. The combination of the sleeve rod 2 and the connecting rod 3 plays the role of supporting and connecting the grounding clamp mechanism, ensuring the stability of the entire grounding structure. By rotating the hexagonal nut 6, the distance between the clamp plate 32 and the installation port 51 can be flexibly adjusted to adapt to grounding wires of different sizes, and the elastic force provided by the spring 34 and the elastic column 33 can be used to enhance the clamping force of the clamp plate 32 while avoiding damage to the grounding wire. The discharge wire 4 connects the grounding clamp mechanism and the sleeve rod 2 to form a complete discharge circuit. When discharge is required, the current can be quickly introduced into the earth through the discharge wire 4 to prevent charge accumulation or excessive current from damaging the equipment.

[0045] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
