Technical Field

[0001] The utility model relates to the technical field of power systems, and particularly relates to a quick-installation grounding device for a power system. Background Technique

[0002] Most of the power transmission lines and related equipment are outdoors and are easily struck by lightning. Tripping of the lines caused by lightning often occurs. To prevent lightning strikes, a grounding device needs to be installed on the transmission line to guide the current generated by lightning strikes to the ground and avoid damage to the conductors or transmission equipment due to excessive lightning voltage.

[0003] To make the grounding device of the power system have a reliable grounding and conductive effect, the grounding device usually uses a grounding pile made of metal. Since the grounding pile is relatively shallow from the ground surface, it is easily affected by the climate, has a large and unstable grounding resistance, thus affecting the conductive performance when the grounding device is used; most of the grounding piles in the prior art are cylindrical, and when installed, they are driven into the ground by external hammering and then fixed by screws, which is relatively slow, thus reducing the working efficiency when installing the grounding device; when the grounding device is used, the grounding wire is generally connected to the grounding post on the surface of the grounding device. Generally, it is not easy to reinforce the grounding wire for the grounding device, thus easily causing the phenomenon of loosening of the grounding wire when the grounding device is used. Content of the Utility Model

[0004] The purpose of the utility model is to provide a quick-installation grounding device for a power system to solve the problems of poor conductive performance, low working efficiency during installation, and easy loosening of the grounding wire when the grounding device is used as proposed in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A quick-installation grounding device for a power system, including a grounding pile, one end of the grounding pile is fixed with a wiring post, a quick-installation mechanism is arranged on the surface of the grounding pile, the quick-installation mechanism consists of a mounting plate, a mounting screw, a turning handle, a groove and a ground drilling cone, an efficient conductive mechanism is arranged inside the grounding pile, the inside of the efficient conductive mechanism includes a water absorption hole, conductive cement, a threaded injection pipe and a threaded cap, a wire fixing mechanism is arranged outside the wiring post, and the wire fixing mechanism consists of a pin slot and a wire fixing component.

[0009] Preferably, a threaded injection pipe is fixed at the top position of the grounding pile, a threaded cover is sleeved on the surface of the threaded injection pipe, and the threaded cover is in threaded fit with the threaded injection pipe.

[0010] Preferably, a pin slot is formed at the top position of the grounding pile, and a wire fixing assembly is arranged outside the wiring post.

[0011] Preferably, the wire fixing assembly includes a pressing frame, an adjusting column, an adjusting cylinder and a stretching spring. A pressing frame is arranged outside the wiring post. The structure of the pressing frame is an L-shaped structure. The pressing frame is in pin connection with the pin slot, and the surface of the pressing frame is closely attached to one end of the wiring post.

[0015] 1. By providing an efficient conductive mechanism, conductive cement is poured into the grounding pile through the threaded injection pipe, and then the threaded cover is put on. Under the threaded fit between the threaded cover and the threaded injection pipe, the threaded cover seals the threaded injection pipe. During use, due to the good conductivity and water absorption of the conductive cement, the conductive cement can improve the conductivity of the nearby dry soil in cooperation with the water absorption holes, so as to realize the efficient conductive function of the grounding device, thereby improving the conductivity of the grounding device during use;

After the connection is completed, the pressing frame can be pulled upward and rotated so that the bottom of the pressing frame is above the pin slot. Subsequently, release the pressing frame, and the pressing frame moves downward under the pulling force of the extension spring to press and fix the grounding wire. At the same time, one end of the pressing frame inserts into the pin slot to prevent the pressing frame from shifting. At the same time, the pressing frame can be guided under the sliding fit of the adjusting column and the adjusting cylinder to realize the wire fixing function of the grounding device, thereby avoiding the phenomenon of the grounding wire loosening when the grounding device is in use.

[0024] The structure of a quick-installation grounding device for a power system provided by the present utility model is as Figure 1 and Figure 2 shown, including a grounding pile 1. One end of the grounding pile 1 is fixed with a terminal 11. A quick-installation mechanism 2 is arranged on the surface of the grounding pile 1. The quick-installation mechanism 2 is composed of an installation disk 21, an installation screw 22, a turning handle 23, a groove 24, and a ground drilling cone 25. An installation disk 21 is fixed at the top position of the grounding pile 1. Grooves 24 are opened at the bottom of the installation disk 21. A turning handle 23 is fixed on the surface of the installation disk 21. An installation screw 22 is fixed on the surface of the grounding pile 1. A ground drilling cone 25 is fixed at the bottom of the grounding pile 1.

[0025] When in use, place the grounding device at the designated position, then press the grounding pile 1 to insert the ground drilling cone 25 into the soil. Subsequently, rotate the turning handle 23 to drive the grounding pile 1 to rotate by the turning handle 23, and drive the installation screw 22 to rotate by the grounding pile 1. Under the action of the installation screw 22, it is convenient for the grounding pile 1 to quickly drill into the soil, making the installation disk 21 closely adhere to the soil surface. At this time, under the action of the groove 24, the friction between the installation disk 21 and the soil can be increased, making the grounding pile 1 more stable. Subsequently, cooperate with the installation disk 21 through screws to fasten the grounding pile 1 to realize the quick-installation function of the grounding device.

[0026] Furthermore, as Figure 3 shown, an efficient conduction mechanism 3 is arranged on the surface of the grounding pile 1. The inside of the efficient conduction mechanism 3 includes a water absorption hole 31, conductive cement 32, a threaded injection pipe 33, and a threaded cap 34. Water absorption holes 31 are circumferentially opened on the surface of the grounding pile 1. The inside of the grounding pile 1 is filled with conductive cement 32. A threaded injection pipe 33 is fixed at the top position of the grounding pile 1. A threaded cap 34 is sleeved on the surface of the threaded injection pipe 33, and the threaded cap 34 is in threaded cooperation with the threaded injection pipe 33.

[0027] During use, conductive cement 32 is poured into the interior of the grounding pile 1 through the threaded injection pipe 33, and then the threaded cap 34 is covered. Under the threaded fit between the threaded cap 34 and the threaded injection pipe 33, the threaded cap 34 seals the threaded injection pipe 33. During use, due to the good conductivity and water absorption of the conductive cement 32, the conductive cement 32 can improve the conductivity of the nearby dry soil in cooperation with the water absorption holes 31 to achieve the high-efficiency conductive function of the grounding device.

[0028] Furthermore, as Figure 4 shown, a wire fixing mechanism 4 is provided on the outer side of the terminal post 11. The wire fixing mechanism 4 is composed of a pin slot 41 and a wire fixing component 42. A pin slot 41 is provided at the top position of the grounding pile 1, and a wire fixing component 42 is provided on the outer side of the terminal post 11. The interior of the wire fixing component 42 includes a pressing frame 421, an adjusting column 422, an adjusting cylinder 423, and a stretching spring 424. A pressing frame 421 is provided on the outer side of the terminal post 11. The structure of the pressing frame 421 is an L-shaped structure. The pressing frame 421 is engaged with the pin slot 41 by pin connection. The surface of the pressing frame 421 is in close contact with one end of the terminal post 11. An adjusting cylinder 423 is rotatably connected to the top position of the grounding pile 1. An adjusting column 422 is provided inside the adjusting cylinder 423. The adjusting column 422 is slidably engaged with the adjusting cylinder 423. One end of the adjusting column 422 is fixedly connected to the surface of the pressing frame 421. Stretch springs 424 are fixed to the other ends of the adjusting columns 422. One end of each stretch spring 424 is fixedly connected to the inner wall of the adjusting cylinder 423.

[0029] During use, the pressing frame 421 can be pulled upward to make the pressing frame 421 away from the pin slot 41. Then, the pressing frame 421 is rotated so that the pressing frame 421 rotates under the action of the adjusting cylinder 423 to make the pressing frame 421 away from the terminal post 11. Then, the grounding wire is connected to the terminal post 11. After the connection is completed, the pressing frame 421 can be pulled upward and rotated so that the bottom of the pressing frame 421 is above the pin slot 41. Then, the pressing frame 421 is released, and the pressing frame 421 moves downward under the pulling force of the stretching spring 424 to press and fix the grounding wire. At the same time, one end of the pressing frame 421 is inserted into the pin slot 41 to prevent the pressing frame 421 from displacing. At the same time, the pressing frame 421 can be guided under the sliding fit between the adjusting column 422 and the adjusting cylinder 423 to achieve the wire fixing function of the grounding device.

[0030] Working principle: When in use, first place the grounding device at the designated position, then press the grounding pile 1 to insert the earth drill cone 25 into the soil. Subsequently, rotate the handle 23, which drives the grounding pile 1 to rotate, and the grounding pile 1 drives the installation screw 22 to rotate. Under the action of the installation screw 22, it is convenient for the grounding pile 1 to quickly drill into the soil, making the installation plate 21 close to the soil surface. At this time, under the action of the groove 24, the friction between the installation plate 21 and the soil can be increased, making the grounding pile 1 more stable. Subsequently, cooperate with the installation plate 21 through screws to fasten the grounding pile 1, so as to realize the rapid installation function of the grounding device, without knocking the grounding pile 1, thus improving the working efficiency during the installation of the grounding device.

[0031] Subsequently, the conductive cement 32 can be poured into the interior of the grounding pile 1 through the threaded injection pipe 33, and then the threaded cap 34 is covered. Under the threaded fit between the threaded cap 34 and the threaded injection pipe 33, the threaded cap 34 blocks the threaded injection pipe 33. When in use, due to the good conductivity and water absorption of the conductive cement 32, the conductive cement 32 can improve the conductive performance of the nearby dry soil in cooperation with the water absorption holes 31, so as to realize the high-efficiency conductive function of the grounding device, thereby improving the conductive performance when the grounding device is in use.

[0032] When in use, the pressing frame 421 can be pulled upward to make the pressing frame 421 away from the pin slot 41. Subsequently, rotate the pressing frame 421, and the pressing frame 421 rotates under the action of the adjusting cylinder 423 to make the pressing frame 421 away from the terminal 11. Subsequently, connect the grounding wire to the terminal 11. After the connection is completed, the pressing frame 421 can be pulled upward and rotated to make the bottom of the pressing frame 421 above the pin slot 41. Then release the pressing frame 421, and the pressing frame 421 moves downward under the pulling force of the extension spring 424 to press and fix the grounding wire. At the same time, one end of the pressing frame 421 is inserted into the pin slot 41 to prevent the displacement of the pressing frame 421. At the same time, the pressing frame 421 can be guided under the sliding fit between the adjusting column 422 and the adjusting cylinder 423, so as to realize the wire fixing function of the grounding device, thereby avoiding the phenomenon of the grounding wire loosening when the grounding device is in use, and finally completing the use work of the grounding device.
