Description

Technical Field

[0001] This utility model relates to the technical field of power grounding piles for power engineering, and specifically discloses power grounding piles for power engineering. Background Technology

[0002] Electrical engineering refers to engineering projects related to the production, transmission, and distribution of electrical energy. In a broader sense, it also includes engineering projects that use electricity as a power source and energy source in various fields. It can also be understood as power transmission and transformation projects. Power transmission lines and related equipment are mostly located outdoors and are susceptible to lightning strikes. Line tripping caused by lightning strikes occurs frequently. In order to prevent lightning strikes, it is generally necessary to install grounding devices on transmission lines.

[0003] Traditional power grounding piles used in power engineering are single, integral metal rod structures with a fixed length. They cannot adjust the pile depth according to geological conditions, and the corrosion protection of the pile is inadequate, affecting the service life of the pile. Therefore, power grounding piles for power engineering are needed to solve this problem. Utility Model Content

[0004] This utility model proposes a power grounding pile for power engineering, which is easy to install and can be flexibly added or removed according to geological requirements, improving its adaptability to different geological conditions; through a three-dimensional protection system of "external protection and internal blocking", the service life of the pile is extended.

[0005] This utility model is implemented as follows: a power grounding pile for power engineering includes a pile body, which is composed of multiple pipe sections connected by threads. A conical tip is welded to the bottom end of the lowest pipe section, and a hexagonal rotating head is provided at the top end of the highest pipe section. Spiral blades are welded to the outer walls of the multiple pipe sections.

[0006] The outer surfaces of the multi-section tube body, conical tip, and spiral blades are coated with a hot-dip galvanized layer and a conductive epoxy resin coating;

[0007] A sealing ring is installed between two adjacent pipe sections.

[0008] As a preferred embodiment of the power grounding pile for power engineering of this utility model, the sealing ring is a weather-resistant rubber sealing ring.

[0009] As a preferred embodiment of the power grounding pile for power engineering of this utility model, the top of the hexagonal rotating head is provided with a reserved interface, and the reserved interface is internally threaded with a sealing cap.

[0010] As a preferred embodiment of the power grounding pile for power engineering of this utility model, the edges of the spiral blades are rounded.

[0011] As a preferred embodiment of the power grounding pile for power engineering of this utility model, the surface of the conical tip is provided with radial reinforcing ribs, and the reinforcing ribs are aligned with the extension direction of the helical blades.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting the pile body as a multi-segment pipe connection, if a certain segment is severely corroded, only that segment needs to be excavated and replaced, without replacing the whole pile. This modular pipe body and spiral blades facilitate the installation of the pile body and allow for flexible addition or subtraction according to geological requirements, thus improving adaptability to different geological conditions.

[0014] 2. The hexagonal rotating head is set in the top section, which can be screwed in with a regular electric wrench or hand tool, achieving quick installation without the need for large machinery;

[0015] 3. The outer double coating covers the pipe body, spiral blades, and conical tip, while the sealing ring protects the internal cavity, forming a three-dimensional protection system of "external protection and internal blockage". This avoids the weak points in corrosion prevention caused by the increased number of interfaces in the multi-section structure, thereby extending the service life of the pile body.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-4 The power grounding pile for power engineering includes a pile body 1, which is composed of multiple pipe sections 2 connected by threads. A conical tip 202 is welded to the bottom end of the lowest pipe section 2, and a hexagonal rotating head 203 is provided at the top end of the highest pipe section 2. Spiral blades 204 are welded to the outer walls of the multiple pipe sections 2.

[0024] The outer surfaces of the multi-section tube 2, the conical tip 202 and the spiral blade 204 are coated with a hot-dip galvanized layer and a conductive epoxy resin coating.

[0025] A sealing ring 201 is installed between two adjacent pipe sections 2.

[0026] In this embodiment: the pile body 1 is set as a multi-section pipe body 2 connected together. If a certain section is severely corroded, only that section needs to be dug out and replaced, without replacing the whole structure. The spiral blades 204 welded to the outer wall of each pipe body 2 and the bottom section are designed with a conical tip 202 to facilitate the screwing of the pile body 1 into the ground. Thus, the modular pipe body 2 and spiral blades 204 make it easy to install the pile body 1 and can be flexibly added or removed according to geological requirements, improving adaptability to different geological conditions.

[0027] With the hexagonal rotating head 203 set in the top section, it can be screwed in with a regular electric wrench or hand tool, achieving quick installation without the need for large machinery;

[0028] A dense zinc-iron alloy layer is formed through metallurgical bonding to resist the corrosion of chemicals in the soil. The conductive epoxy resin coating fills the tiny pores in the galvanized layer, blocking the penetration of moisture and oxygen while maintaining the conductivity of the pile body 1. The sealing ring 201 can prevent soil moisture from entering. Furthermore, the outer double coating covers the pipe body 2, the spiral blade 204, and the conical tip 202, while the sealing ring 201 protects the internal cavity, forming a three-dimensional protection system of "external protection and internal blocking". This avoids the weak points in corrosion prevention caused by the increased number of interfaces in the multi-section structure, thereby extending the service life of the pile body 1.

[0029] As a technical optimization of this utility model, the sealing ring 201 is a weather-resistant rubber sealing ring.

[0030] In this embodiment, the sealing ring 201 is a weather-resistant rubber sealing ring, which can form a physical isolation barrier to prevent soil moisture from entering the interior of the pipe body 2 through the thread gap.

[0031] As a technical optimization of this utility model, the top of the hexagonal rotating head 203 is provided with a reserved interface 3, and the reserved interface 3 is internally threaded with a sealing cover 301.

[0032] In this embodiment: a conductive spring sheet is embedded in the inner wall of the reserved interface 3, and an elastic conductive contact that abuts against the spring sheet is fixed on the inner side of the sealing cover 301. The contact is connected to the external monitoring module through a wire. The sealing cover 301 can isolate rainwater and dust to prevent the reserved interface 3 from being corroded or blocked.

[0033] As a technical optimization of this utility model, the edges of the spiral blade 204 are rounded.

[0034] In this embodiment, the edges of the spiral blades 204 are rounded to reduce soil friction damage to the anti-corrosion layer.

[0035] As a technical optimization of this utility model, the surface of the conical tip 202 is provided with radial reinforcing ribs, and the reinforcing ribs extend in the same direction as the spiral blade 204.

[0036] In this embodiment: the radial ribs enhance the cone tip's resistance to gravel impact and work in conjunction with the spiral blades in the 204 direction to reduce the risk of deflection during screwing in.

[0037] The working principle and usage process of this utility model are as follows: By setting the pile body 1 as a multi-section pipe body 2 connected together, if a certain section is severely corroded, only that section needs to be dug out and replaced, without the need for overall replacement. The spiral blades 204 welded to the outer wall of each pipe body 2 and the bottom section designed as a conical tip 202 make it easy to screw the pile body 1 into the ground. Thus, the modular pipe body 2 and spiral blades 204 make it easy to install the pile body 1, and can be flexibly added or removed according to geological requirements, improving adaptability to different geological conditions.

[0038] With the hexagonal rotating head 203 set in the top section, it can be screwed in with a regular electric wrench or hand tool, achieving quick installation without the need for large machinery;

[0039] A dense zinc-iron alloy layer is formed through metallurgical bonding to resist the corrosion of chemicals in the soil. The conductive epoxy resin coating fills the tiny pores in the galvanized layer, blocking the penetration of moisture and oxygen while maintaining the conductivity of the pile body 1. The sealing ring 201 can prevent soil moisture from entering. Furthermore, the outer double coating covers the pipe body 2, the spiral blade 204, and the conical tip 202, while the sealing ring 201 protects the internal cavity, forming a three-dimensional protection system of "external protection and internal blocking". This avoids the weak points in corrosion prevention caused by the increased number of interfaces in the multi-section structure, thereby extending the service life of the pile body 1.
