Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering grounding devices, in particular to a grounding device. Background Art

[0002] The main purpose of grounding is to conduct electric current so that it can travel back and forth between the earth or equivalent metal conductors. It belongs to the category of conductive connection and can be specifically divided into permanent grounding and temporary grounding. In addition to effectively preventing electric shock to humans, grounding can also ensure the safe operation of the power system and provide effective protection for the insulation of lines and electrical equipment. Existing electrical engineering grounding devices require construction workers to drive grounding piles into the ground to a depth of about one and a half meters. This method requires construction workers to install manually, which is more troublesome. In addition, when the ground is uneven, it is difficult to fix the metal rod inserted into the ground. When it is hit, the metal rod is easily knocked, affecting the functionality of the grounding.

[0003] In the patent document with the publication number CN219917625U, an electrical engineering grounding device is disclosed. It is provided with a shell structure and a connection structure. By rotating the connection block, the connection cylinder is driven to rotate the first gear, and the outer second gear rotates so that the fixed rod inside the sleeve is inserted under the ground to reinforce the surrounding land. On different grounds, the fixed insertion is still achieved to ensure that the grounding rod remains grounded. When the connection cylinder rotates, the grounding rod goes deep downward, and there is no need to knock the grounding rod into the ground, thereby ensuring the stability of the grounding and improving the safety of the electrical equipment. In the process of implementing this technical solution, the inventor found that there are at least the following problems in the prior art:

[0004] When the above device is actually used, the connecting tube is screwed to the ground rod, so that when the connecting tube rotates, the ground rod is driven down and inserted into the ground. Although it is more convenient than hammering the ground rod into the ground, it is necessary to process threads on the ground rod to make it screwed to the connecting tube, and there is still a problem of low working efficiency. At the same time, it is necessary to continuously rotate the connecting tube to make the ground rod inserted into the ground. When the connecting tube rotates, it will drive the fixing rod and the barb to rotate, causing the soil at the fixing rod and the barb to loosen, affecting the overall stability of the device.

[0005] Therefore, it is necessary to provide a grounding device to solve the above technical problems. Utility Model Content

[0006] In view of this, an object of the present invention is to provide a grounding device to solve the problems raised in the above background technology.

[0008] In order to facilitate the insertion of the grounding rod into the ground, preferably, the pressing assembly includes a screw rod rotatably arranged inside the fixed cylinder, a moving block is screwed on the screw rod, a pressure plate is fixedly connected to one side of the moving block, and an installation groove is opened on the outer side of the fixed cylinder.

[0009] In order to improve the stability of the base, preferably, the fixing assembly includes fixing columns arranged at the four corners of the base, a screw is threaded in the fixing column, a plug is fixedly connected to the bottom of the screw, and a knob is fixedly connected to the top of the screw.

[0010] In order to facilitate the forward and reverse rotation of the screw rod, preferably, a rotating wheel is fixed to the top bolt of the screw rod.

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

[0013] The grounding device drives the screw rod to rotate by turning the knob. When the screw rod rotates, it moves downward in the fixed column, thereby driving the insertion rod to move downward and insert into the ground to support and fix the base. By rotating the screw rod, the screw rod drives the moving block to descend. The moving block slides on the inner wall of the fixed cylinder and drives the pressure plate to descend. The grounding rod is pressed down by the pressure plate to insert the grounding rod into the ground. BRIEF DESCRIPTION OF THE DRAWINGS
