Description

Technical Field

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

[0002] An electrical cabinet is a metal-enclosed cabinet that centrally controls and protects electrical equipment. It is made of steel plates or aluminum alloys and has functions such as dustproof, moisture-proof, explosion-proof, and corrosion-resistant. Various electrical components such as circuit breakers and contactors are installed inside to achieve circuit control, measurement, regulation, and protection.

[0003] Before an existing electrical cabinet is installed on the ground, it is generally necessary to build a concrete base on the ground. After the concrete solidifies, the cabinet body is installed. This process is relatively time-consuming, and a grounding pin is generally provided on the electrical cabinet as a grounding protection, which is used to prevent the electrical cabinet from leaking electricity and injuring people. The current grounding pin design of the electrical cabinet has some shortcomings. First, the grounding pin connected to the outside of the electrical cabinet by a grounding wire is easily pulled out by scavengers, which brings potential risks to the safe use of the electrical cabinet. Secondly, the function of the grounding pin is relatively single, and it is only used for grounding protection, and its potential function is not fully utilized. Utility Model Content

[0006] Optionally, a grounding wire is soldered to one side of the top of the grounding rod, and radial grooves for accommodating four grounding wires are provided on two relatively vertical top surfaces of the base, and a sealing gasket is bonded between the base and the cabinet, and a wire inlet groove is provided on the sealing gasket, and the wiring terminals of the grounding wire extend into the cabinet along the radial groove and the wire inlet groove.

[0009] Compared with the prior art, the utility model provides a reinforced grounding device for an electrical cabinet, which has the following beneficial effects:

[0010] The utility model arranges fixed blocks at the four corners of the base and grounding rods on the fixed blocks, which not only realizes the conductive function but also effectively fixes the entire base to ensure the stability of the cabinet.

[0016] Example: See Figures 1 to 3, a reinforced grounding device for an electrical cabinet, comprising a base 1, a cabinet body 2 fixed on the base 1, the base 1 being in the shape of a rectangular frame, and having a fixed block 3 integrally formed at each of its four corners, the fixed blocks 3 being respectively located on two relatively horizontal sides of the base 1, and the fixed blocks 3 being provided with countersunk openings 4, each of which is provided with a grounding rod 5 connected to the ground, and an inclined groove 6 being provided on the bottom side of the grounding rod 5, and two relatively horizontal sides of the base 1 being respectively provided with two opposite guide blocks 7 in the center, the guide blocks 7 A guide groove 8 coinciding with the center line of the inclined groove 6 is provided on the top, and a grounding rod 9 is provided on the guide block 7 which is movably inserted into the inclined groove 6 along the guide groove 8. The bottom ends of the grounding rod 5 and the grounding rod 9 are both tapered. The grounding rod 5 can be inserted into the countersunk mouth 4 and fixed underground to ensure that the base 1 is stably fixed on the ground. The presence of the guide block 7 and the guide groove 8 helps to guide the grounding rod 9 so that it can move in a specific direction underground and be inserted into the inclined groove 6 on the grounding rod 5, further making the connection between the base 1 and the ground more stable.
