Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment grounding, in particular to a magnetic grounding connection component and a protective grounding device. Background Art

[0002] At the construction site, the temporary power supply system usually adopts the TN-S system grounding, which requires that the metal shell of the electrical equipment must be connected to the protective grounding, so as to effectively prevent the electrical equipment from being electrified due to insulation damage, which may endanger the safety of personnel and equipment. For example: repeated grounding of the three-level power supply panel, the shell grounding of the welding machine, and the grounding of the general conventional welding machine.

[0003] If electrical equipment such as power panels and welding machines need to be placed inside or outside large-diameter pipelines and tanks for construction, and there are no dedicated grounding points in the surrounding area, the conventional method is: first, the repeated grounding wires of the outer shells of electrical equipment such as power panels and welding machines are directly overlapped on the surface of the pipelines and tanks. This can easily cause poor contact of the electrical equipment during construction, which may cause the risk of electric shock; second, in order to ensure reliable connection of the outer shell of the electrical equipment, the conventional method is to weld temporary grounding screw fixing points on the inner and outer walls of the pipelines and tanks, and then use grounding copper noses, grounding wire clamps, etc. to connect. Although this grounding method meets the standards and requirements for reliable grounding connection, the temporary grounding screws welded on the inner and outer walls of the pipelines and tanks must be removed, polished, and anti-corroded after the relevant operations are completed. This has the disadvantages of cumbersome procedures, low efficiency, and poor protection of finished products. Utility Model Content

[0045] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0046] like Figure 1 As shown, the magnetic grounding connection assembly provided in this embodiment includes: a magnetic connection component 100 and a conductive component 200; the magnetic connection component 100 is connected to the conductive component 200, and the magnetic connection component 100 is configured to generate magnetic force to connect to the metal part to be grounded. It should be noted that the metal part to be grounded is a metal part such as a pipeline and a tank body that needs to be grounded; when the magnetic connection component 100 is connected to the metal part to be grounded, the conductive component 200 abuts against the metal part to be grounded so that the metal part to be grounded is grounded through the conductive component 200; the conductive component 200 is configured to be able to move relative to the magnetic connection component 100, so that both the conductive component 200 and the magnetic connection component 100 are connected to the metal part to be grounded.

[0047] The magnetic grounding connection assembly provided in this embodiment connects the magnetic connection component 100 to the metal part to be grounded through the magnetic force generated by the magnetic connection component 100, and adjusts the relative position of the conductive component 200 and the magnetic connection component 100 so that after the magnetic connection component 100 is connected to the metal part to be grounded, the conductive component 200 abuts against the metal part to be grounded, and the conductive component 200 is used to provide grounding protection for the metal to be grounded, thereby alleviating the technical problem that the grounding method of electrical equipment in the prior art requires processing of the pipeline or tank, resulting in complicated overall grounding operation.

[0048] Regarding the structure and shape of the magnet connection member 100, specifically:

[0049] The magnetic connecting component 100 specifically includes a magnetic base body 110 and a soft magnetic material 120; a permanent magnet is arranged in the magnetic base body 110, and the permanent magnet is specifically a cylindrical strong permanent magnet. A soft magnetic material 120 is protrudingly arranged on the outer surface of the magnetic base body 110. The soft magnetic material 120 can be magnetized by the permanent magnet, so that the soft magnetic material 120 has magnetism. During the installation of the magnetic grounding connection component, the soft magnetic material 120 is first magnetized by the permanent magnet, and the magnetic base body 110 is moved to make the soft magnetic material 120 close to the surface of the pipeline and the tank body. The soft magnetic material 120 is tightly attached to the surface of the pipeline and the tank body under the action of magnetic force, and the magnetic connecting component 100 can be connected to the pipeline and the tank body.

[0050] The magnet connecting component 100 also includes a magnetization conversion switch 130; the magnetization conversion switch 130 is rotatably set on the magnetic base body 110, the magnetization conversion switch 130 is connected to the permanent magnet, and the magnetization conversion switch 130 is specifically a rotating rod with a handle. The handle drives the rotating rod to rotate, so that the magnetization conversion switch 130 drives the permanent magnet to rotate. When the magnetic pole of the permanent magnet is facing the soft magnetic material 120, the soft magnetic material 120 has magnetism. Specifically, by rotating the external handle in a clockwise direction, the positions of the two poles of the cylindrical permanent magnet inside change, that is, when the N or S pole of the permanent magnet is facing the soft magnetic material 120, the soft magnetic material 120 is magnetized and has a strong magnetism, so that it can be firmly adsorbed on the metal surface.

[0051] Conversely, when the magnetic grounding connection component needs to be removed, the external handle is rotated counterclockwise to restore the position of the internal cylindrical magnet, and the magnetism of the soft magnetic material 120 disappears, so that the magnetic grounding connection component can be detached from the metal surface and removed.

[0052] The magnetic grounding connection assembly also includes a bracket 300; the bracket 300 is in the shape of a rectangular strip, slightly wider than the magnetic base on both sides, the magnetic base body 110 is fixed to the bracket 300 by connecting bolts 400, and holes for the conductive component 200 are provided at the wide positions on both sides. The material of the bracket 300 can use an insulating plate of a certain thickness and strength, or a metal plate with an insulating layer of a certain thickness. Its main function is to fix the magnetic base body 110 and the conductive component 200.

[0053] Regarding the structure and shape of the conductive member 200, specifically:

[0054] The conductive component 200 includes a conductive copper rod 210, a first adjusting nut 220 and a second adjusting nut 230; the conductive copper rod 210 passes through the bracket 300, the surface of the conductive copper rod 210 is a threaded pile, and the end of the conductive copper rod 210 that contacts the metal piece to be grounded is set to an arc structure, and the arc structure is specifically a semicircular structure, which helps the conductive copper rod 210 to contact the surface of the pipeline and the tank more reliably, and the conductive copper rod 210 is threadedly connected with the first adjusting nut 220 and the second adjusting nut 230, and the first adjusting nut 220 and the second adjusting nut 230 are respectively arranged on both sides of the bracket 300, and the first adjusting nut 220 and the second adjusting nut 230 is tightly attached to the bracket 300. By screwing the first adjusting nut 220 and the second adjusting nut 230, the relative position of the conductive copper rod 210 on the bracket 300 can be adjusted, and then the position of the conductive copper rod 210 relative to the magnetic base body 110 can be adjusted. It can be suitable for pipes and tanks of various sizes. When it needs to be placed inside a pipe or a tank, the magnetic base body 110 can be adjusted to a convex style slightly higher than the conductive copper rods 210 on both sides according to the arc shape of the pipe or the tank; anyway, when it needs to be placed on the outer surface of the pipe or the tank, the magnetic base body 110 can be adjusted to a concave style slightly lower than the conductive copper rods on both sides according to the arc shape of the pipe or the tank.

[0056] The conductive component 200 also includes an assisting elastic member 260 and a third adjusting nut 270; the third adjusting nut 270 is threadedly connected to the conductive copper rod 210; the assisting elastic member 260 is sleeved on the conductive copper rod 210, and one end of the assisting elastic member 260 is connected to the second adjusting nut 230, and the other end of the assisting elastic member 260 is connected to the third adjusting nut 270. The assisting elastic member 260 helps to stabilize and adjust the force of the copper rod when adjusting the copper rod up and down.

[0057] Gaskets 280 are provided between the wing nut 240 and the copper nose 250 , between the copper nose 250 and the first adjusting nut 220 , between the second adjusting nut 230 and the assisting elastic member 260 , and between the third adjusting nut 270 and the assisting elastic member 260 .

After installation, the connection is firm, so that the grounding connection of the electrical equipment is effective and reliable, ensuring the working safety of the construction personnel. It not only meets the standard requirements for grounding of electrical equipment during on-site large-diameter pipelines, inside and outside tanks, but also is more conducive to workers' operation, and can more quickly improve work efficiency and finished product protection. It can be flexibly applied to various industries with large-diameter pipelines, tank assembly, welding, installation and other processes.
