Description

Technical Field

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

[0002] The grounding wire is an electric wire directly connected to the ground, which can be called a safe return line. When danger occurs, it transfers the high voltage directly to the ground. When a leakage occurs in the distribution cabinet, the outer casing of the distribution cabinet is energized. When a person touches it, a loop is formed, causing electric shock. If there is a grounding wire, the resistance of the human body is greater than the resistance of the grounding wire. The grounding wire will conduct the current into the earth, thereby protecting human life safety.

[0003] When installing a grounding electrode in an existing distribution cabinet, the grounding electrode needs to be inserted into the ground. Due to the different conditions on the ground surface suitable for installing the grounding electrode, it is necessary to timely adjust the position of the grounding electrode into the ground. However, the grounding electrode of the distribution cabinet is fixedly installed. When facing a ground surface that cannot be inserted, the ground wire needs to be disassembled and replaced before it can be inserted into the ground for installation. Utility Model Content

[0024] Example 1

[0025] like Figure 1-Figure 3 As shown,

[0026] A movable grounding device for a power distribution cabinet comprises a box 1, a switch 2 and a sleeve 3. A leg support 102 is fixed to the bottom of the box 1, a cabinet door 101 is fixed to the front side of the box 1, and a protection box 103 is fixed to the rear side of the box 1.

[0027] A support plate 201 is fixed inside the box 1, and a switch 2 is fixed on the surface of the support plate 201. An insulating support rod 203 is fixed inside the box 1 above the support plate 201, and a ground plate 204 is fixed at one end of the insulating support rod 203. The ground plate 204 is installed to protect the safety of personnel in case of leakage. On the other hand, it allows the switch 2 inside the box 1 to be detected when leakage occurs, and then the power is cut off to ensure safety.

[0028] A connecting screw head 202 is fixed to one end of the ground plate 204, a nut 205 is fixed to one end of the bottom of the ground plate 204, a leakage protection column 206 is fixed to the surface of the nut 205, the function of the leakage protection column 206 is to allow leakage to be transmitted through the leakage protection column 206, and will not harm the maintenance personnel behind, and a guide piece 105 is fixed inside the box 1, the function of the guide piece 105 is to allow the electricity on the surface of the box 1 to be transmitted through the guide piece 105 when leakage occurs, and the guide piece 105 is connected to the leakage protection column 206 through the nut 205. A protective cover 207 is fixed to the surface of the leakage protection column 206, and the protective cover 207 is fixed to the box 1.

[0029] One end of the leakage protection column 206 extends and is located inside the protection box 103. A copper plate 208 is fixed to one end of the leakage protection column 206 located inside the protection box 103. A connecting plate 209 is fixed to the copper plate 208. A leakage circuit 210 is fixed to the connecting plate 209. The leakage circuit 210 is connected to a connector 211. The connector 211 is fixedly mounted on a hoop 301. The hoop 301 is clamped on the outside of the sleeve 3. The sleeve 3 is fixed to the rear side of the box body 1 through a support plate 104. The sleeve 3 is rotatably connected to the support plate 104. A grounding electrode 302 is fixed to the side wall of the hoop 301. The grounding electrode 302 is connected to the L-shaped guide rail 303.

[0030] An adjusting rod 304 is provided at the top of the sleeve 3, and a knob 305 is provided at the top of the adjusting rod 304. The knob 305 can drive the adjusting rod 304 to drive the sleeve 3 to rotate, and the sleeve 3 drives the hoop 301 and the grounding electrode 302 to rotate, thereby changing the direction of the grounding device.

[0031] When the utility model is used:

[0032] The switch 2 or line inside the box 1 leaks electricity, causing the surface of the box 1 to be in danger of leakage. At this time, the leakage is transmitted to the leakage protection column 206 through the installed guide plate 105, and then transmitted to the grounding electrode 302 through the copper plate 208, the connecting plate 209 and the leakage line 210, so that it can transmit the leakage to the ground to ensure the safety of the personnel behind. When the grounding device is in use, due to the problem of the surface being suitable for installing the grounding electrode, it is necessary to change the position of the grounding device. At this time, the sleeve 3 can be rotated by using the adjustment rod 304, and then the grounding position of the grounding electrode 302 is adjusted.

[0033] The utility model adjusts the position of the grounding electrode through the sleeve and the L-shaped guide rail, so that the grounding electrode can be rotated to change the position of the ground, saving the trouble of disassembly. The grounding electrode and the distribution cabinet are assembled through the cooperation of the sleeve and the hoop, so that it will not fall off easily. The surface of the sleeve is equipped with a hoop, which can be used to connect the ground wire and the distribution cabinet during disassembly to ensure safety.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
