Description

Technical Field

[0001] This utility model relates to the technical field of power supply, and in particular to a pre-contained substation lightning protection grounding device. Background Technology

[0002] A prefabricated modular substation is a type of substation that integrates major equipment such as transformers, high-voltage switchgear, and secondary protection equipment into a single unit using a prefabricated modular structure. It undergoes design, assembly, wiring, and commissioning in a factory, and is then transported to the site for rapid modular installation and commissioning, enabling the substation to be constructed and put into operation quickly.

[0003] The existing patent publication number CN213878456U discloses a lightning protection grounding device for a prefabricated substation, including a lightning rod installed on the top of the prefabricated substation. The grounding device is electrically connected to the lightning rod via a conductor. The grounding device includes a reaction section containing a thermite, and a spray nozzle on the side of the reaction section. Molten iron produced after igniting the thermite is sprayed out through the nozzle, improving the stability and conductive area of ​​the grounding device. This device allows for rapid installation of grounding wires without the need for excavation; the wires are simply nailed to the ground, and the equipment is then activated. The grounding wires have a tighter contact with the earth, a larger contact area, and can conduct a larger current, greatly protecting the safety of the prefabricated substation.

[0004] In existing technologies, when installed on the ground, the molten iron produced by igniting the thermite is sprayed out through a high-pressure nozzle. The strong pressure generates a force that pushes the reaction section upward, which not only poses a safety hazard of being thrown outward, but also causes the reaction section to be inserted obliquely into the ground, affecting the normal installation of the grounding device. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems existing in the current prefabricated substation lightning protection grounding device, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a pre-containment type substation lightning protection grounding device, which aims to solve the problem that "in the existing technology, when the thermite is installed on the ground, the molten iron produced by igniting the thermite will be sprayed out through the high-pressure injection port. The strong pressure will generate a force that pushes the reaction part upward, which not only poses a safety hazard of being thrown outward, but also causes the reaction part to be inserted obliquely into the ground, affecting the normal installation of the grounding device".

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A prefabricated substation lightning protection grounding device includes:

[0010] The main unit includes a pipe body, with a soil-breaking cone installed at the lower end of the pipe body and a limit ring installed at the upper end of the pipe body;

[0011] The locking unit includes a movable ring that is slidably connected to the surface of the tube. Three sets of locking blocks are fixedly connected to the outer surface of the movable ring, and each locking block is rotatably connected to a connecting rod. The other end of each of the three sets of connecting rods is rotatably connected to a moving block, and each moving block is rotatably connected to a rotating tube. Each of the three sets of rotating tubes is slidably connected to an insert rod, and a fixing component is provided at the upper end of the insert rod.

[0012] As a preferred embodiment of the pre-containment substation lightning protection grounding device of this utility model, the fixing component includes an upper fixing ring that is slidably connected to the pipe body, and the upper fixing ring is fixedly connected to the movable ring. The outer surface of the upper fixing ring is provided with three sets of slots that cooperate with the insertion rod, and the inner wall surface of the slots is engaged with the insertion rod. The upper surface of the upper fixing ring is movably connected with three sets of cover plates, and all the cover plates are fixedly connected to the insertion rod.

[0013] As a preferred embodiment of the pre-cabin type substation lightning protection grounding device of this utility model, wherein: a fixing block is fixedly connected to one side surface of the movable ring, and a threaded bolt is threadedly connected inside the fixing block, and one end of the threaded bolt is movably connected to one side surface of the pipe body.

[0014] As a preferred embodiment of the pre-cabin type substation lightning protection grounding device of this utility model, one end of the threaded bolt is fixedly connected to a protective pad, and the protective pad is made of rubber.

[0015] As a preferred embodiment of the pre-cabin type substation lightning protection grounding device of this utility model, wherein: the lower ends of the three sets of plug rods are all fixedly connected to cone blocks, and the inner diameter of the upper surface of the cone block is larger than the inner diameter of the plug rod.

[0016] As a preferred embodiment of the pre-cabin type substation lightning protection grounding device of this utility model, the inner wall surfaces of the three sets of slots are all fixedly connected with anti-slip pads, and the anti-slip pads are movably connected to the surface of the insertion rod.

[0017] The beneficial effects of this utility model are:

[0018] Insert the tube into the designated position, then pull the insert rod upwards to allow it to slide upwards within the slot and rotating tube, bringing the upper surface of the cone block into contact with the rotating tube. Next, twist the threaded bolt inside the fixed block to disengage the protective pad from the tube surface, pushing the movable ring and upper retaining ring downwards on the tube surface. Then, twist the threaded bolt again to bring the protective pad into contact with the tube surface, fixing the movable ring in place. Finally, move the insert rod to slide it out from the inner wall of the slot, simultaneously causing the sliding connecting rotating tube to move. The rotating tube drives the moving block of the rotating connection to move, which in turn drives the connecting rod of the rotating connection to rotate on the surface of the clamping block. This allows the cone block to point to the corresponding position. Then, the cover plate is pressed down, and the insert rod, which is fixedly connected to the cover plate, breaks into the soil under the action of the cone block. At the same time, the cover plate and the rotating tube are in contact. Finally, the reaction section inside the tube is activated. This not only allows the molten iron to solidify the tube and the insert rod together, further improving stability, but also limits the position of the tube, preventing it from tilting or swinging under the reaction force of the reaction section, thus improving safety.

[0029] Reference Figure 1-4 This utility model provides a pre-installed substation lightning protection grounding device, comprising:

[0030] The main unit 100 includes a pipe body 101, a ground-breaking cone 103 installed at the lower end of the pipe body 101, a limit ring 102 installed at the upper end of the pipe body 101, and a reaction section provided inside the pipe body 101, which is existing technology and is used to improve the stability and conductive area of ​​the grounding.

[0031] The locking unit 200 includes a movable ring 201 that is slidably connected to the surface of the pipe body 101. Three sets of locking blocks 202 are fixedly connected to the outer surface of the movable ring 201, and each locking block 202 is rotatably connected to a connecting rod 203. The other end of each of the three sets of connecting rods 203 is rotatably connected to a moving block 204, and each of the moving blocks 204 is rotatably connected to a rotating tube 205. Each of the three sets of rotating tubes 205 is slidably connected to an insertion rod 206, and the upper end of the insertion rod 206 is provided with a fixing component 207. When the three sets of insertion rods 206 are inserted into the soil, the pipe body 101 can be limited.

[0032] The fixing component 207 includes an upper fixing ring 207a that is slidably connected to the tube body 101 and is fixedly connected to the movable ring 201. The outer surface of the upper fixing ring 207a has three sets of slots 207b that cooperate with the insertion rod 206, and the inner wall surface of the slots 207b is engaged with the insertion rod 206. The upper surface of the upper fixing ring 207a is movably connected to three sets of cover plates 207c, and all cover plates 207c are fixedly connected to the insertion rod 206 to limit and store the insertion rod 206 so that the insertion rod 206 will not swing freely.

[0033] Furthermore, a fixing block 208 is fixedly connected to one side surface of the movable ring 201, and a threaded bolt 209 is threadedly connected inside the fixing block 208. One end of the threaded bolt 209 is movably connected to one side surface of the tube body 101, which can flexibly fix the movable ring 201 at any surface position of the tube body 101.

[0034] Furthermore, a protective pad 210 is fixedly connected to one end of the threaded bolt 209, and the protective pad 210 is made of rubber material, which protects the surface of the pipe body 101 when the threaded bolt 209 is in contact with the surface of the pipe body 101.

[0035] Furthermore, the lower ends of the three sets of insertion rods 206 are all fixedly connected to cone blocks 211, and the inner diameter of the upper surface of the cone block 211 is larger than the inner diameter of the insertion rod 206. This not only makes it easier for the insertion rod 206 to penetrate into the soil, but also allows the insertion rod 206 to slide out from the inside of the rotating tube 205.

[0036] Furthermore, the inner wall surfaces of the three sets of slots 207b are all fixedly connected with anti-slip pads 207d, and the anti-slip pads 207d are movably connected to the surface of the insertion rod 206, so that the insertion rod 206 can only be manually pulled out from the inside of the slot 207b.

[0037] During use, insert the tube body 101 into the designated position, then pull the insertion rod 206 upward to make it slide upward inside the slot 207b and the rotating tube 205, and make the upper surface of the cone block 211 fit against the rotating tube 205. Next, twist the threaded bolt 209 to rotate it inside the fixing block 208, causing the protective pad 210 to disengage from the surface of the tube body 101, pushing the movable ring 201 and the upper fixing ring 207a to slide downward on the surface of the tube body 101. Then twist the threaded bolt 209 to rotate it so that the protective pad 210 fits against the surface of the tube body 101, fixing the position of the movable ring 201 on the surface of the tube body 101. Finally, move the insertion rod 206 to... The insertion rod 206 slides out from the inner wall of the slot 207b. At the same time, the insertion rod 206 drives the sliding connecting rotating tube 205 to move, which in turn causes the rotating tube 205 to drive the rotating connecting moving block 204 to move. The moving block 204 drives the rotating connecting rod 203 to rotate on the surface of the slot 202, so that the cone block 211 can point to the corresponding position. Then, the cover plate 207c is pressed down. The insertion rod 206, which is fixedly connected to the cover plate 207c, breaks into the soil under the action of the cone block 211. At the same time, the cover plate 207c is in contact with the rotating tube 205. Finally, the reaction part inside the tube body 101 is activated, which enables the molten iron to solidify the tube body 101 and the insertion rod 206 together.
