Description

Technical Field

[0001] This application relates to the technical field of grounding protection devices, specifically a grounding protection device for power line selection and site selection in loess areas. Background Technology

[0002] Power line and facility site selection in loess areas is a comprehensive engineering task involving the selection of locations for power lines or facilities in loess regions. It requires consideration of topography, geology, construction conditions, and policy requirements to ensure safety, economy, and environmental protection. Protective grounding is grounding implemented to prevent the metal casings of electrical equipment, the framework of distribution equipment, and line towers from becoming energized and endangering personal and equipment safety. Protective grounding involves reliably connecting the normally non-energized but potentially energized (i.e., metal structural parts insulated from energized parts) of electrical appliances to a grounding electrode using a conductor. A grounding pin is a needle-shaped metal rod used for grounding, typically made of copper or aluminum. Its function is to ground electrical equipment or lines to ensure the safe operation of the power system.

[0003] When using a grounding pin, it should first be connected to the line and then inserted into the ground to protect the circuit. However, if the grounding pin is inserted directly into the ground, it is not stable enough and may shake or fall off, reducing the protective effect of the grounding pin.

[0004] Therefore, there is an urgent need for a grounding protection device for power line selection and site selection in loess areas to solve the problem of unstable grounding pins. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a grounding protection device for power line selection and site selection in loess areas, which has the advantage of improving the protection effect of the grounding pin and solving the problem of insufficient stability of the grounding pin.

[0006] To achieve the above objectives, this application provides the following technical solution: a grounding protection device for power line selection and site selection in loess areas, comprising a fixed plate, a support cylinder, a grounding needle body, and a connector. The support cylinder is fixedly connected to the top center of the fixed plate by bolts. The grounding needle body is inserted into the inside of the fixed plate and the support cylinder. The connector is located on the top of the grounding needle body. Clamping mechanisms are provided on the upper and lower sides of the fixed plate, and a fixing mechanism is provided at the bottom of the fixed plate.

[0007] The clamping mechanism includes a pressure sleeve, a push plate, a connecting sleeve, a clamping sleeve, a clamping block, and a sliding groove. The pressure sleeve is threaded to the top of the support cylinder, the push plate is welded to the top of the pressure sleeve, the connecting sleeve is rotatably connected to the bottom of the fixing plate, the clamping sleeve is threaded to the bottom of the connecting sleeve, the clamping block is welded to the inner surface of the clamping sleeve, and the sliding groove is formed on the outer surface of the grounding needle body. The clamping block is slidably connected to the sliding groove on the outer side of the grounding needle body.

[0008] When the pressure sleeve rotates, it can press against the top of the connector, thereby fixing the top of the grounding pin. At the same time, when the clamp moves the slide upward, it can clamp the bottom of the grounding pin body, so that the grounding pin can be stably installed inside the fixing plate, not easily shaken, preventing the grounding pin body from detaching from the ground, and allowing the grounding pin to provide safe protection for the power line selection and site selection in loess areas.

[0009] Preferably, the connecting sleeve is connected to the fixed plate via a bearing.

[0010] Preferably, a rubber pad is installed at the center of the top of the push plate.

[0011] Preferably, the pressure sleeve is pressed against the top of the connector.

[0012] Preferably, the fixing mechanism includes a first support rod, a second support rod, a first limiting piece, and a second limiting piece. One end of the first support rod is welded to the bottom of the fixing plate, and the other end of the first support rod is welded to the top of the second support rod. The first limiting piece and the second limiting piece are welded to the outer surface of the second support rod.

[0013] Preferably, several sets of the limiting piece one and limiting piece two are distributed in a circular pattern on the outer surface of the support rod two.

[0014] In summary, this application includes at least one of the following beneficial effects:

[0015] 1. The grounding protection device used for power line selection and site selection in the loess area, when the line passes through the rubber pad and connects to the connector, the grounding needle body passes through the support cylinder and the fixing plate and is inserted into the ground. The construction personnel push the push plate, which drives the pressure sleeve to rotate. When the pressure sleeve rotates, it can press against the top of the connector, thereby fixing the top of the grounding needle. At the same time, the construction personnel rotate the connecting sleeve, which drives the clamp to move up and down. The clamp drives the clamp block to move in the slide groove. When the clamp drives the slide groove to move upward, it can clamp the bottom of the grounding needle body, so that the grounding needle can be stably installed inside the fixing plate, not easily shaken, preventing the grounding needle body from detaching from the ground, so that the grounding needle can provide safe protection for the power line selection and site selection in the loess area.

[0016] 2. In the grounding protection device used for power line selection and site selection in the loess area, when the fixing plate is fixed to the ground, the fixing plate is inserted into the ground through the pressure sleeve and the push plate. The rubber pad and the connecting sleeve limit and fix the pressure sleeve and the push plate, making the pressure sleeve and the push plate less prone to shaking, improving the stability of the grounding protection device, and allowing the grounding protection device to stably protect the power line selection and site selection in the loess area.

[0024] The technical solutions of 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1-6 A grounding protection device for power line selection and site selection in loess areas includes a fixed plate 1, a support cylinder 2, a grounding needle body 3, and a connector 4. The support cylinder 2 is fixedly connected to the top middle position of the fixed plate 1 by bolts. The grounding needle body 3 is inserted into the inside of the fixed plate 1 and the support cylinder 2. The connector 4 is located on the top of the grounding needle body 3. The power line selection and site selection line in loess areas is connected to the connector 4. The grounding needle body 3 passes through the support cylinder 2 and the fixed plate 1 and is inserted into the ground to protect the circuit. The upper and lower sides of the fixed plate 1 are provided with clamping mechanisms, and the bottom of the fixed plate 1 is provided with a fixing mechanism.

[0026] Specifically, the clamping mechanism includes a pressure sleeve 111, a push plate 112, a connecting sleeve 114, a clamping sleeve 115, a clamping block 116, and a sliding groove 117. The pressure sleeve 111 is threaded to the top of the support cylinder 2. The push plate 112 is welded to the top of the pressure sleeve 111. A rubber pad 113 is installed at the middle position of the top of the push plate 112. The connecting sleeve 114 is rotatably connected to the bottom of the fixing plate 1. The clamping sleeve 115 is threaded to the bottom of the connecting sleeve 114. The pressure sleeve 111 is pressed against the top of the connector 4. The connecting sleeve 114 is connected to the fixing plate 1 through a bearing. The clamping block 116 is welded to the inner surface of the clamping sleeve 115. The sliding groove 117 is opened on the outer surface of the grounding needle body 3. The clamping block 116 is slidably connected to the sliding groove 117 on the outer side of the grounding needle body 3.

[0027] With the above technical solution, when the line passes through the rubber pad 113 and connects to the connector 4, the grounding needle body 3 passes through the support cylinder 2 and the fixing plate 1 and is inserted into the ground. The construction personnel push the protrusion on the outside of the push plate 112, the protrusion drives the push plate 112 to rotate, the push plate 112 drives the pressure sleeve 111 to rotate, and when the pressure sleeve 111 rotates, it moves down and can press against the top of the connector 4, thereby fixing the top of the grounding needle.

[0028] At the same time, the construction workers rotate the connecting sleeve 114 and grip the grounding needle body 3. The connecting sleeve 114 drives the clamp 115 to move up and down. The clamp 115 drives the clamp block 116 to move inside the slide groove 117. When the clamp 115 drives the slide groove 117 to move up, it can clamp the bottom of the grounding needle body 3, so that the grounding needle can be stably installed inside the fixing plate 1, which is not easy to shake and prevents the grounding needle body 3 from detaching from the ground. This allows the grounding needle to provide safe protection for the power line selection and site selection in the loess area.

[0029] Specifically, the fixing mechanism includes support rod 1 211, support rod 212, limiting plate 1 213 and limiting plate 214. One end of support rod 1 211 is welded to the bottom of the fixing plate 1, and the other end of support rod 1 211 is welded to the top of support rod 212. Limiting plate 1 213 and limiting plate 214 are welded to the outer surface of support rod 212. Several sets of limiting plates 1 213 and limiting plate 214 are located on the outer surface of support rod 212 in a circular distribution.

[0030] With the above technical solution, when the fixing plate 1 is fixed to the ground, the fixing plate 1 is inserted into the ground through the pressure sleeve 111 and the push plate 112. The rubber pad 113 and the connecting sleeve 114 limit and fix the pressure sleeve 111 and the push plate 112, making the pressure sleeve 111 and the push plate 112 less prone to shaking, thereby improving the stability of the grounding protection device and enabling the grounding protection device to stably protect the power line selection and site selection in the loess area.

[0031] When in use, the pressure sleeve 111 can press against the top of the connector 4 when it rotates, thereby fixing the top of the grounding needle. At the same time, when the clamp 115 drives the slide groove 117 to move upward, it can clamp the bottom of the grounding needle body 3, so that the grounding needle can be stably installed inside the fixing plate 1, not easily shaken, preventing the grounding needle body 3 from detaching from the ground, and allowing the grounding needle to provide safe protection for the power line selection and site selection in the loess area.

[0032] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
