Description

Technical Field

[0001] The utility model relates to the technical field of grounding protection, in particular to a grounding protection device for a power distribution network. Background Art

[0002] A grounding protection device refers to a device specifically used to protect electrical equipment and personal safety. It connects the metal casing of the electrical equipment to a grounding electrode buried underground. When the electrical equipment leaks or the insulation is damaged, the leakage current will flow back to the ground through the grounding line. The grounding protection device can detect this current change and cut off the power supply in time when the current exceeds the set safety value, thereby effectively preventing electric shock accidents and equipment damage.

[0003] During the installation process of traditional grounding protection devices, the grounding electrode is usually buried directly in the ground before connecting to the electrical equipment. This lacks effective shock-absorbing measures. When the device is affected by external environmental factors, it is prone to shaking or even falling. This not only reduces the stability of the connection between the device and the electrical equipment, but may also pose a threat to the working quality and electrical safety of the device.

[0004] Therefore, it is necessary to design a grounding protection device for a power distribution network. Utility Model Content

[0005] In order to overcome the shortcomings of traditional grounding protection devices that lack effective shock-absorbing measures and are prone to shaking and falling after being affected by external environmental factors, which seriously affects the stability of the connection between the device and electrical equipment, the technical problem to be solved by the utility model is: to provide a grounding protection device for an electric power distribution network.

[0006] The technical implementation scheme of the utility model is: a grounding protection device for an electric power distribution network, comprising a base, a first protective cover, a second protective cover, a movable plate, a second spring, a damping rod, a grounding column, a wiring port and an adapter, a groove is provided on the top of the base, a first protective cover is movably provided in the groove of the base, a second protective cover is fixedly connected to the groove of the base, the second protective cover is located inside the first protective cover, a damping rod is provided between the second protective cover and the first protective cover, a second spring is wound around the damping rod, a movable plate is slidably connected to one side of the second protective cover, a grounding column is provided inside the second protective cover, one end of the grounding column passes through the base, an adapter is connected to the grounding column, a wiring port is provided on the end of the adapter away from the grounding column, and through holes for inserting wires are provided on the tops of the second protective cover and the first protective cover.

[0007] In a preferred embodiment of the present invention, a stabilizing nail is movably provided on the top of the base.

[0008] In a preferred embodiment of the utility model, one end of the first spring is fixedly connected in the base groove, and the other end of the first spring is fixedly connected to a stop plate, and the stop plate contacts the first protective cover.

[0009] In a preferred embodiment of the utility model, a wire protection tube is commonly provided at the through holes of the first protective cover and the second protective cover. The wire protection tube is slidably connected to the first protective cover and fixedly connected to the second protective cover.

[0010] In a preferred embodiment of the utility model, a threaded groove is provided on the grounding column, and a hand wheel is fixedly connected to the grounding column.

[0011] In a preferred embodiment of the utility model, a limiting block is fixedly connected to the base, and the limiting block is threadedly connected to the grounding column.

[0012] The beneficial effects are: 1.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0021] Embodiment: A grounding protection device for a power distribution network, such as Figure 1-Figure 4 As shown, it includes a base 1, a first protective cover 2, a second protective cover 3, a movable plate 301, a second spring 4, a damping rod 401, a grounding column 5, a wiring port 6 and an adapter 7. A groove is provided on the top of the base 1, and the first protective cover 2 is movably arranged in the groove of the base 1. The second protective cover 3 is fixedly connected to the groove of the base 1, and the second protective cover 3 is located inside the first protective cover 2. A damping rod 401 is provided between the second protective cover 3 and the first protective cover 2, and the second spring 4 is wound around the damping rod 401. The movable plate 301 is slidably connected to one side of the second protective cover 3. A grounding column 5 is provided inside the second protective cover 3, one end of the grounding column 5 passes through the base 1, and the grounding column 5 is connected to the adapter 7. The end of the adapter 7 away from the grounding column 5 is provided with a wiring port 6. Through holes for wires to be inserted are provided on the tops of the second protective cover 3 and the first protective cover 2. Here, the second spring 4 is deformed after being subjected to force, and then the damping rod 401 absorbs the force generated by the deformation of the second spring 4 and converts it into other forms of energy for dissipation, thereby achieving a shock-absorbing effect.

[0022] like Figure 1 As shown, a stabilizing nail 101 is movably provided on the top of the base 1. Here, the design of the stabilizing nail 101 can firmly fix the base 1 in a predetermined placement position, prevent the base 1 from shaking due to external influences, and effectively improve the stability of the device.

[0023] like Figure 2 As shown, one end of the first spring 102 is fixedly connected in the groove of the base 1, and the other end of the first spring 102 is fixedly connected to a push plate 103, and the push plate 103 contacts the first protective cover 2. Here, when the first protective cover 2 shakes, the first protective cover 2 applies a force to the corresponding push plate 103, and then the push plate 103 applies a force to the first spring 102, so that the first spring 102 is deformed by the force, and finally the first spring 102 applies a reaction force to the push plate 103 by relying on the resilience of the first spring 102, so that the first spring 102 pushes the bottom plate to reset, thereby playing a certain limiting role on the first protective cover 2, preventing the first protective cover 2 from excessive shaking, and further ensuring the stability of the device.

[0024] like Figure 1 and Figure 3As shown, a wire protection tube 201 is commonly provided at the through hole of the first protective cover 2 and the second protective cover 3. The wire protection tube 201 is slidably connected to the first protective cover 2 and fixedly connected to the second protective cover 3. Here, the design of the wire protection tube 201 can remain relatively stable when the first protective cover 2 shakes, thereby preventing the first protective cover 2 from affecting the grounding wire during the shaking process, ensuring the stability of the connection between the device and the grounding wire, and promoting effective and stable operation of the device.

[0025] like Figure 4 As shown, a threaded groove 501 is provided on the grounding column 5, and a handwheel 502 is fixedly connected to the grounding column 5. Here, the design of the threaded groove 501 and the handwheel 502 can facilitate workers to easily and quickly insert the grounding column 5 into the ground. At the same time, relying on the design of the threaded groove 501, the contact area between the grounding column 5 and the ground is further increased, thereby improving the stability of the grounding column 5.

[0026] like Figure 4 As shown, a limit block 8 is fixedly connected to the base 1, and the limit block 8 is threadedly connected to the grounding column 5. Here, the design of the limit block 8 can limit and guide the grounding column 5, so that the grounding column 5 can be stably inserted into the ground, preventing the grounding column 5 from subsequently falling over, thereby improving the stability of the device.

[0027] When in use, place the device in a predetermined placement position, then insert one end of the grounding column 5 into the ground, then pass the grounding wire through the through holes of the first protective cover 2 and the second protective cover 3 in turn, and connect it to the wiring port 6 of the grounding column 5, thereby completing the wiring work of the device, then slide the movable plate 301 to seal the second protective cover 3, and then completely cover the first protective cover 2 on the second protective cover 3. When the device is hit, the first protective cover 2 shakes due to the impact, and the first protective cover 2 applies a force to the second spring 4 during the shaking process, causing it to deform under the force, and then the damping rod 401 absorbs the force generated by the deformation of the second spring 4 and converts it into other forms of energy for dissipation, thereby achieving a shock-absorbing effect and ensuring the stability of the second protective cover 3 and the terminal. The work is now completed.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
