Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a grounding post for power engineering. Background Technology

[0002] In power engineering, when outdoor circuits are erected, they are susceptible to lightning strikes. Line tripping caused by lightning strikes occurs frequently. To prevent lightning strikes, grounding devices need to be installed on transmission lines to conduct the current generated by lightning strikes to the ground and prevent damage to conductors or transmission equipment from lightning voltage. Therefore, grounding posts are used to conduct the current to the ground.

[0003] Existing power grounding posts are mostly driven directly into the ground to conduct current to the ground. However, after being driven into the ground, these power grounding posts are not very stable vertically. Under the action of external forces, the underground power grounding posts may tilt and shift, which is not stable enough and reduces the stability of the device. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a grounding post for power engineering.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a grounding post for power engineering, including a grounding post body, an installation rod fixedly provided on the bottom surface of the grounding post body, a fixed cone provided on the bottom surface of the installation rod, a plurality of supporting plates distributed in a circumferential array on the outer wall of the installation rod, and a supporting component for supporting the supporting plates being provided on the installation rod.

[0006] By adopting the above technical solution, when workers need to use the grounding post body, they drive the grounding post body into the ground using a fixed cone. Subsequently, after it is driven into the ground, workers need to use a spreading assembly to spread the spreading plate, thereby reducing the probability of the grounding post tilting and improving the stability of the device.

[0007] Furthermore, a rotating groove is provided through the upper surface of the mounting rod. The spreading assembly includes a threaded rod rotatably disposed in the rotating groove, a fixed ring sleeved on the outer wall of the mounting rod, and a movable ring threadedly connected to the threaded rod. The fixed ring is fixed to the mounting rod, the movable ring is threadedly connected to the lower end of the threaded rod, the threaded rod is fixed to the fixed cone, and a control component for controlling the movement of the spreading plate is provided on both the fixed ring and the movable ring.

[0008] Furthermore, the control component includes a first rotating seat arranged in a circumferential array on the outer walls of the fixed ring and the moving ring, a second rotating seat symmetrically arranged on the inner wall of the support plate, and a rotating component rotatably arranged in the first rotating seat. The other end of the rotating component is rotatably connected to the second rotating seat, and adjacent rotating components are rotatably connected to each other.

[0009] By adopting the above technical solution, after the workers drive the grounding post into the ground, they need to rotate the threaded rod, which causes the moving ring to move upward under the action of the threaded rod. This causes the first rotating seat, which is fixed to the moving ring, to move upward, and then the rotating part to rotate under the action of the first rotating seat. This causes the rotating part to rotate relative to the first and second rotating seats, and then the spreading plate to spread open under the action of the rotating seats. This reduces the probability of the grounding post tilting and improves the stability of the device.

[0010] Furthermore, a rotating groove is provided through the upper surface of the grounding post body, the rotating groove is directly opposite the rotating slot, and a rotating rod is rotatably arranged in the rotating groove, the rotating rod and the threaded rod are fixed to each other.

[0011] By adopting the above technical solution, when the worker needs to rotate the threaded rod, the worker needs to rotate the rotating rod, which in turn causes the threaded rod to rotate under the action of the rotating rod. In this process, the difficulty of the worker rotating the threaded rod is reduced, thereby reducing the difficulty of the worker's work.

[0012] Furthermore, an annular groove is formed on the inner wall of the rotating groove, and an annular block is rotatably arranged in the annular groove, the annular block being fixed to the rotating rod.

[0013] By adopting the above technical solution, when the rotating rod rotates, the annular block rotates under the action of the threaded rod. During this process, the annular block limits the rotating rod, thereby reducing the probability of the rotating rod moving up and down, which in turn reduces the probability of the threaded rod moving up and down, and further reduces the probability of the moving ring moving up and down when subjected to external force, thus improving the stability of the device.

[0014] Furthermore, a limit rod is provided on two adjacent rotating parts. The limit rod passes through the rotating parts and is rotatably connected to them. Two limit rings are sleeved on the outer wall of the limit rod. The side walls of the two limit rings that are close to each other abut against the side walls of the two rotating parts that are far apart from each other.

[0015] By adopting the above technical solutions, the limiting rod improves the stability of two adjacent rotating parts during rotation and reduces the probability of wobbling during rotation, thereby improving the stability of the device. The limiting ring reduces the probability of the limiting rod separating from the rotating parts, thus improving the stability of the device.

[0016] Furthermore, two mutually symmetrical connecting cones are fixedly installed on the outer wall of the expansion plate.

[0017] By adopting the above technical solution, when the support plate is opened, the connecting cone is inserted into the soil. During this process, the probability of the grounding post tilting is further reduced, thereby improving the stability of the device.

[0018] In summary, this utility model has the following beneficial effects: 1. In this application, when workers need to use the grounding post body, they drive the grounding post body into the ground using a fixed cone. Subsequently, after it is driven into the ground, workers need to use a spreading assembly to spread the spreading plate, thereby reducing the probability of the grounding post tilting and improving the stability of the device; 2. In this application, after the worker drives the grounding post body into the ground, the worker needs to rotate the threaded rod, which causes the moving ring to move upward under the action of the threaded rod, thereby driving the first rotating seat fixed to the moving ring to move upward, and then causing the rotating part to rotate under the action of the first rotating seat, so that the rotating part rotates relative to the first rotating seat and the second rotating seat, thereby causing the supporting plate to open under the action of the rotating seat, thereby reducing the probability of the grounding post tilting, and thus improving the stability of the device; 3. In this application, when the worker needs to rotate the threaded rod, the worker needs to rotate the rotating rod, which in turn causes the threaded rod to rotate under the action of the rotating rod. In this process, the difficulty of the worker rotating the threaded rod is reduced, thereby reducing the difficulty of the worker's work. Attached Figure Description

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] like Figure 1-4 As shown in the illustration, this application discloses a grounding post for power engineering, including a grounding post body 1, an mounting rod 11, a fixing cone 12, a support plate 13, a support assembly 3, and a control assembly 4. The grounding post body 1 is a cylindrical structure with a vertical axis. The mounting rod 11 is a cylindrical rod structure with its axis coinciding with the axis of the grounding post body 1, and the mounting rod 11 is fixedly mounted on the bottom surface of the grounding post body 1. The fixing cone 12 is mounted on the bottom surface of the mounting rod 11, with its axis coinciding with the axis of the mounting rod 11. The support plate 13 has multiple plates arranged in a circumferential array on the outer wall of the mounting rod 11.

[0023] When workers need to use the grounding post body 1, they drive it into the ground using the fixing cone 12. After it is driven into the ground, workers use the spreading assembly 3 to spread the spreading plate 13, thereby reducing the probability of the grounding post tilting and improving the stability of the device.

[0024] A rotating groove 2 is formed through the upper surface of the mounting rod 11. A spreading assembly 3 is mounted on the mounting rod 11 to spread the spreading plate 13. The spreading assembly 3 includes a threaded rod 31, a fixed ring 32, and a movable ring 33. The threaded rod 31 is rotatably mounted in the rotating groove 2, and its axis coincides with the axis of the mounting rod 11. The threaded rod 31 is fixed to the fixed cone 12. The fixed ring 32 is sleeved on the outer wall of the mounting rod 11, and its axis coincides with the axis of the mounting rod 11. The fixed ring 32 is fixed to the mounting rod 11. The movable ring 33 is threadedly connected to the threaded rod 31, and its axis coincides with the axis of the threaded rod 31. The movable ring 33 is threadedly connected to the lower end of the threaded rod 31.

[0025] Control component 4 is disposed on the fixed ring 32 and the movable ring 33, and is used to control the movement of the supporting plate 13. Control component 4 includes a first rotating seat 41, a second rotating seat 42, and rotating members 43. Multiple first rotating seats 41 are arranged in a circumferential array on the outer walls of the fixed ring 32 and the movable ring 33. Multiple second rotating seats 42 are symmetrically disposed on the inner walls of the multiple supporting plates 13. Multiple rotating members 43 are rotatably disposed within the multiple first rotating seats 41, and the other end of each rotating member 43 is rotatably connected to an adjacent second rotating seat 42, with adjacent rotating members 43 being rotatably connected to each other.

[0026] After the grounding post body 1 is driven into the ground, the worker needs to rotate the threaded rod 31, which causes the moving ring 33 to move upward under the action of the threaded rod 31. This causes the first rotating seat 41, which is fixed to the moving ring 33, to move upward, and then the rotating part 43 to rotate under the action of the first rotating seat 41. This causes the rotating part 43 to rotate relative to the first rotating seat 41 and the second rotating seat 42, which in turn causes the spreading plate 13 to spread open under the action of the rotating seat. This reduces the probability of the grounding post tilting and improves the stability of the device.

[0027] To reduce the difficulty of the work for the workers, a rotating groove 5 is provided through the upper surface of the grounding post body 1. The rotating groove 5 is directly opposite the rotating groove 2. A rotating rod 51 is rotatably installed in the rotating groove 5, and the rotating rod 51 is fixed to the threaded rod 31. When the worker needs to rotate the threaded rod 31, the worker needs to rotate the rotating rod 51, which in turn causes the threaded rod 31 to rotate under the action of the rotating rod 51. In this process, the difficulty of rotating the threaded rod 31 is reduced, thereby reducing the difficulty of the worker's work.

[0028] To improve the stability of the device, an annular groove 6 is formed on the inner wall of the rotating groove 5, and an annular block 61 is rotatably disposed within the annular groove 6. The annular block 61 is fixed to the rotating rod 51. When the rotating rod 51 rotates, the annular block 61 rotates under the action of the threaded rod 31. During this process, the annular block 61 limits the rotation of the rotating rod 51, thereby reducing the probability of the rotating rod 51 moving up and down, which in turn reduces the probability of the threaded rod 31 moving up and down, and further reduces the probability of the moving ring 33 moving up and down when subjected to external force, thus improving the stability of the device.

[0029] To improve the stability of the device, a limit rod 7 is provided on two adjacent rotating parts 43. The limit rod 7 passes through the rotating part 43 and is rotatably connected to it. Two limit rings 71 are sleeved on the outer wall of the limit rod 7. The side walls of the two limit rings 71 that are close to each other abut against the side walls of the two rotating parts 43 that are far apart. The limit rod 7 improves the stability of the two adjacent rotating parts 43 during rotation and reduces the probability of wobbling during rotation, thereby improving the stability of the device. The limit rings 71 reduce the probability of the limit rod 7 separating from the rotating part 43, thereby improving the stability of the device.

[0030] To improve the stability of the device, two symmetrical connecting cones 8 are fixedly installed on the outer wall of the expansion plate 13. When the expansion plate 13 is opened, the connecting cones 8 are inserted into the soil. During this process, the probability of the grounding post tilting is further reduced, thereby improving the stability of the device.

[0031] The working principle of a grounding post in this embodiment is as follows: When workers need to use the grounding post body 1, they drive the grounding post body 1 into the ground using the fixing cone 12. Subsequently, after it is driven into the ground, workers need to use the spreading component 3 to spread the spreading plate 13, thereby reducing the probability of the grounding post tilting and improving the stability of the device.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
