Description

Technical Field

[0001] This utility model relates to the technical field of grounding devices for electrical engineering, specifically a grounding structure for electrical engineering. Background Technology

[0002] The primary purpose of grounding is to conduct current, allowing it to travel between the earth or an equivalent metallic conductor. It falls under the category of conductive connections and can be specifically divided into permanent grounding and temporary grounding. Besides effectively preventing electric shock, grounding ensures the safe operation of the power system and provides effective protection for the insulation of lines and electrical equipment.

[0003] A search revealed that the announcement number is CN219917625U, and the name is "An Electrical Engineering Grounding Device," which includes a housing structure. Research and analysis showed that although the device can still achieve fixed insertion on different ground surfaces, ensuring that the grounding rod remains in a grounded state, the grounding rod goes deeper into the ground when the connecting cylinder rotates, eliminating the need to knock the grounding rod into the ground, thus ensuring the stability of the grounding and improving the safety of electrical equipment. However, it still has the following disadvantages to some extent.

[0004] For example, the overall installation process is relatively complex, requiring workers to spend a lot of effort and time during installation, resulting in low work efficiency. At the same time, it does not have a shockproof effect. When the ground is vibrated, the grounding device is easily loosened, which can lead to the grounding part falling off and causing the grounding device to fail and fail to achieve the conductivity effect. In order to solve the above technical problems, we have designed a grounding structure for electrical engineering. Utility Model Content

[0005] The purpose of this utility model is to provide a grounding structure for electrical engineering, which has the advantages of convenient installation and shock resistance. It solves the problems that the overall installation steps are relatively complicated, and the grounding device is not shock-resistant. When the ground is vibrated, the grounding device is easy to loosen, which leads to the grounding part falling off and the grounding device failing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grounding structure for electrical engineering, comprising a mounting base plate, threaded rods fixedly welded to the four corners of the top of the mounting base plate, a mounting top plate extending through the top of the threaded rods, a nut threadedly fitted onto the surface of the threaded rods and at the top of the mounting top plate, a grounding contact fixedly welded to the center of the bottom of the mounting top plate, a connecting ground cage fixedly welded to the outer ring of the bottom of the mounting base plate, a grounding assembly extending through the center of the top of the mounting base plate, the grounding assembly comprising a grounding rod, the grounding rod being fixedly fixed to the center of the top of the mounting base plate, the bottom of the grounding rod extending to below the connecting ground cage and horizontally fixedly welded to a conductive crossbar, a grounding nail fixedly welded to the bottom of the conductive crossbar, a mounting base fixedly connected to the top of the grounding rod, a spring fixedly installed at the bottom of the inner cavity of the mounting base, and a conductive plate fixedly installed on the top of the spring.

[0007] Preferably, a connecting seat is fixedly welded to the center of the left and right sides of the top of the mounting plate, a power cord is fixedly connected to the surface of the connecting seat, the connecting seat is made of conductive material, and the bottom of the connecting seat is electrically connected to the grounding contact through a wire.

[0008] Preferably, the surface of the grounding rod is covered with a protective sleeve, which is made of insulating material.

[0009] Preferably, the outer surface of the conductive plate is in sliding contact with the inner wall of the mounting base, and both the conductive plate and the spring are made of conductive metal material.

[0010] Preferably, the mounting base has limit holes through both the left and right sides, and the conductive plate has limit plates fixedly connected to both the left and right sides. The end of the limit plate away from the conductive plate extends into the inner cavity of the limit hole and slides in contact with its inner wall.

[0011] Preferably, the grounding contact is made of a conductive metal material, and the bottom of the grounding contact extends into the inner cavity of the mounting base and makes sliding contact with its inner wall.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention connects the power cord to the conductive position and uses a connector to connect the grounding contact for conductivity, making it contact with the conductive plate. This allows the current to be conducted into the ground through the spring, grounding rod, conductive crossbar, and grounding nail, effectively transferring the current from the surface of the equipment to the ground. Simultaneously, the elasticity of the spring ensures that the conductive plate remains in close contact with the grounding contact, maintaining continuous conductivity. When the mounting plate vibrates and shakes, the spring pushes the conductive plate to continue contacting the grounding contact, thus achieving a shock-resistant effect. Attached Figure Description

[0021] Please see Figures 1-6 A grounding structure for electrical engineering includes a mounting base plate 1. Threaded rods 4 are fixedly welded to the four corners of the top of the mounting base plate 1. A mounting top plate 5 penetrates the top of each threaded rod 4. Nuts 8 are threaded onto the surface of each threaded rod 4 and located at the top of the mounting top plate 5. A grounding contact 9 is fixedly welded to the center of the bottom of the mounting top plate 5. A connecting ground cage 2 is fixedly welded to the outer ring of the bottom of the mounting base plate 1. The connecting ground cage 2 can enclose the grounding location, preventing the device from shaking due to loose soil and improving the installation stability of the device. A grounding component 3 is penetrated through the center of the top of the mounting base plate 1. The grounding component 3 includes a grounding contact... The grounding rod 31 is fixed at the center of the top of the mounting base plate 1. The bottom of the grounding rod 31 extends to the bottom of the connecting cage 2 and is horizontally fixedly welded with a conductive crossbar 33. The bottom of the conductive crossbar 33 is fixedly welded with a ground nail 34. By setting the ground nail 34, the device can be stably fixed in the soil to prevent the device from shaking. The top of the grounding rod 31 is fixedly connected to the mounting base 35. The bottom of the inner cavity of the mounting base 35 is fixedly installed with a spring 37. By setting the spring 37, the conductive plate 38 can be elastically supported so that it can always be in contact with the grounding contact 9. The top of the spring 37 is fixedly installed with the conductive plate 38.

[0022] Please see Figure 3A connecting seat 7 is fixedly welded to the center of the top left and right sides of the mounting plate 5. A power line 6 is fixedly connected to the surface of the connecting seat 7. The connecting seat 7 is made of conductive material. The bottom of the connecting seat 7 is electrically connected to the grounding contact 9 through a wire. By setting the power line 6, the current output position can be connected from different directions, which can adapt to different installation positions and improve the adaptability of the device.

[0023] Please see Figure 5 and Figure 6 The surface of the grounding rod 31 is covered with a protective sleeve 32, which is made of insulating material. By setting the protective sleeve 32, the grounding rod 31 can be prevented from being interfered with by current, and at the same time, the grounding rod 31 can be prevented from being damaged by soil erosion.

[0024] Please see Figure 5 and Figure 6 The outer surface of the conductive plate 38 is in sliding contact with the inner wall of the mounting base 35. Both the conductive plate 38 and the spring 37 are made of metal conductive material.

[0025] Please see Figure 5 and Figure 6 Limiting holes 36 are provided on both the left and right sides of the mounting base 35. Limiting plates 39 are fixedly connected to both the left and right sides of the conductive plate 38. The end of the limiting plate 39 away from the conductive plate 38 extends into the inner cavity of the limiting hole 36 and slides in contact with its inner wall. By setting the limiting plate 39 and the limiting hole 36, the movement of the conductive plate 38 can be guided to avoid it from shaking, so that the conductive plate 38 can move up and down stably and maintain smooth conductivity.

[0026] Please see Figure 4 The grounding contact 9 is made of conductive metal, and the bottom of the grounding contact 9 extends into the inner cavity of the mounting base 35 and makes sliding contact with its inner wall.

[0027] In use, the mounting base plate 1 and the connecting cage 2 are pre-buried underground, and the ground nails 34 are inserted into the soil. The equipment is placed on top of the mounting base plate 1, and a hole is drilled at the position of the threaded rod 4 at the bottom of the equipment so that the threaded rod 4 passes through the bottom of the equipment. Then, the mounting top plate 5 is placed on top of the surface of the threaded rod 4, and the nut 8 is screwed into the surface of the threaded rod 4 so that the bottom of the grounding contact 9 extends into the mounting base 35. The conductive position is connected through the power cord 6, and the grounding contact 9 is connected to the connecting base 7 for conduction, so that it contacts the conductive plate 38. This allows the current to be conducted into the ground through the spring 37, the grounding rod 31, the conductive crossbar 33, and the ground nails 34, which can effectively conduct the current on the surface of the equipment to the ground. At the same time, with the elasticity of the spring 37, the conductive plate 38 is always in close contact with the grounding contact 9, so that it is always connected and conductive. When the mounting top plate 5 is shaken up and down by vibration, the spring 37 pushes the conductive plate 38 to continue to contact the grounding contact 9, thereby achieving the anti-vibration effect.

[0028] In summary, this grounding structure for electrical engineering, through the cooperation of the mounting base plate 1, connecting cage 2, grounding component 3, threaded rod 4, mounting top plate 5, power line 6, connecting seat 7, nut 8, and grounding contact 9, solves the problems of complex overall installation steps, lack of shock resistance, and easy loosening of the grounding device when the ground is vibrated, leading to the grounding part falling off and the grounding device failing.
