Description

Technical Field

[0001] The invention relates to the technical field of grounding locking, in particular to a grounding locking device for an electrical switch cabinet. Background Art

[0002] The power distribution cabinet can be used for the control and protection of electrical facilities in industrial and mining enterprises, power plants and substations, and the safety performance of the power distribution cabinet is particularly important. Although the electrical distribution cabinet in the prior art has set up relevant electrical and mechanical designs to prevent misoperation in terms of the grounding switch, due to factors such as the large operating force of the grounding switch, these settings often cannot meet the requirements of preventing misoperation after a long time. Therefore, it is necessary to directly set a locking device on the grounding switch operating mechanism to ensure that after the grounding switch is opened, except for individual professionals, other people cannot close the grounding switch. Similarly, after the grounding switch is closed, except for individual professionals, other people cannot open the grounding switch, so as to ensure the absolute safety of system equipment and maintenance personnel.

[0003] Most of the existing grounding locking devices for electrical switch cabinets are not convenient for quick installation and disassembly of the grounding switch, which makes it inconvenient for operators to repair the grounding switch. In addition, a cooling fan is usually arranged inside the existing electrical switch cabinet to achieve heat dissipation of the electrical switch cabinet. However, since the position of the existing cooling fan is relatively fixed, it is difficult to perform heat dissipation at other positions inside the electrical switch cabinet, thereby affecting the use effect of the electrical switch cabinet. For this reason, we propose a grounding locking device for an electrical switch cabinet. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0030] Example 1

[0037] And an installation component 7 arranged inside the electrical switch cabinet body 1, the installation component 7 includes a heat dissipation mechanism 71 fixedly installed on the inner wall of the electrical switch cabinet body 1, and a fixing mechanism 72 is arranged below the heat dissipation mechanism 71. By setting the heat dissipation mechanism 71, the heat dissipation treatment of the grounding switch body 7216 can be facilitated by the heat dissipation blades 718 to improve the stability of the grounding switch body 7216 during operation. By setting the fixing mechanism 72, the grounding switch body 7216 can be clamped and fixed by the clamping plate 7212, so as to clamp the grounding switch body 7216 inside the electrical switch cabinet body 1, thereby improving the use effect of the grounding switch body 7216.

[0038] The heat dissipation mechanism 71 includes a motor 1 711 fixedly mounted on the inner wall of the electrical switch cabinet body 1, a bidirectional threaded rod 712 fixedly mounted on the output end of the motor 1 711, a sleeve block 713 threadedly connected to the outer wall of the bidirectional threaded rod 712, a rotating block 714 hingedly mounted on the bottom of the sleeve block 713, a bottom plate 715 hingedly mounted on the other end of the rotating block 714, a motor 2 716 fixedly mounted on the side wall of the rotating block 714, an output shaft 717 fixedly mounted on the output end of the motor 2 716, a heat dissipation blade 718 fixedly mounted on the outer wall of the other end of the output shaft 717, a connecting plate 719 fixedly mounted on the side wall of the bottom plate 715, a dust removal brush 7110 fixedly mounted on the other end of the connecting plate 719, and the side wall of the dust removal brush 7110 is slidably connected to the inner wall of the electrical switch cabinet body 1.

[0039] In this embodiment, by setting the heat dissipation mechanism 71, when the grounding switch body 7216 is working inside the electrical switch cabinet body 1, the operator can turn on the motor 1 711 and the motor 2 716 to cause the motor 1 711 to rotate with the bidirectional threaded rod 712. During the rotation of the bidirectional threaded rod 712, the two sleeve blocks 713 will move. When the two sleeve blocks 713 are relatively close, the rotating block 714 will be rotated through the hinge. After the motor 2 716 is started, the output shaft 717 will rotate to cause the heat dissipation blades 718 to rotate. After the rotating block 714 rotates, the motor 2 is cooled. 716 is rotated, thereby changing the heat dissipation position of the heat dissipation blade 718, improving the heat dissipation effect inside the electrical switch cabinet body 1, and dissipating the heat of the grounding switch body 7216 to improve the stability of the grounding switch body 7216 during operation. During the rotation of the rotating block 714, the bottom plate 715 is prompted to move up and down. During the up and down movement of the bottom plate 715, the connecting plate 719 moves up and down with the dust removal brush 7110, prompting the dust removal brush 7110 to clean the dust on the inner wall of the electrical switch cabinet body 1, thereby improving the working effect inside the electrical switch cabinet body 1.

[0040] Example 2

[0041] Based on Example 1, a preferred embodiment of a grounding locking device for an electrical switch cabinet provided by the present invention is as follows: Figures 1 to 6 As shown: the fixing mechanism 72 includes a rectangular block 721 fixedly mounted on the bottom of the inner wall of the electrical switch cabinet body 1, a support plate 722 is fixedly mounted on the top of the rectangular block 721, a rectangular groove 723 is opened on the top of the support plate 722, the bottom of the rectangular block 721 is rotatably connected to a rotating rod 724 through a bearing, a rotating plate 725 is fixedly mounted on the middle outer wall of the rotating rod 724, a fixed column 726 is fixedly mounted on the top of the other end of the rotating plate 725, a movable plate 727 is fixedly mounted on the outer wall of the fixed column 726, and a moving block 728 is movably mounted on the other end of the movable plate 727 through a hinge, the outer wall of the moving block 728 is slidably connected to the inner wall of the rectangular groove 723, and the bottom outer wall of the moving block 728 is fixed A side plate 729 is fixedly installed, and the bottom outer wall of the rotating rod 724 is rotatably connected to a T-block 7210 through a bearing. A cylinder 7211 is fixedly installed on the side wall of the T-block 7210, and the output end of the cylinder 7211 is fixedly connected to the side wall of the side plate 729. A clamping plate 7212 is fixedly installed on the top of the moving block 728, and a sleeve 7213 is fixedly installed on the side wall of the clamping plate 7212. A connecting spring 7214 is fixedly installed on the inner wall of the sleeve 7213, and the other end of the connecting spring 7214 is fixedly connected to an extrusion rod 7215, and the other end of the extrusion rod 7215 is slidably connected to a grounding switch body 7216, and the bottom of the grounding switch body 7216 is slidably connected to the top of the support plate 722.

[0042] In this embodiment, by setting the fixing mechanism 72, when it is necessary to lock the grounding switch body 7216, the operator can place the grounding switch body 7216 on the top of the support plate 722, and then close the cylinder 7211, so that the output end of the cylinder 7211 is contracted, and the side plate 729 is moved. When the side plate 729 moves, the moving block 728 and the clamping plate 7212 are moved. During the movement of the moving block 728, the movable plate 727 is rotated through the hinge. During the rotation of the movable plate 727, the rotating plate 725 is caused to rotate around the fixed column 726. The rotating rod 724 rotates, prompting the other moving block 728 and the clamping plate 7212 to move, so that the two clamping plates 7212 are close to the grounding switch body 7216. After the two clamping plates 7212 are close to the grounding switch body 7216, the outer wall of the grounding switch body 7216 will squeeze the squeezing rod 7215, prompting the squeezing rod 7215 to squeeze the connecting spring 7214. Under the reaction of the connecting spring 7214, the grounding switch body 7216 will be clamped and fixed by the squeezing rod 7215, so as to improve the stability of the grounding switch body 7216 during operation.

[0043] Furthermore, there are four supporting legs 2, which are equal in size and fixedly installed at the four corners of the bottom of the electrical switch cabinet body 1 at equal distances. Through this arrangement, the four supporting legs 2 can fix the electrical switch cabinet body 1, thereby improving the stability of the electrical switch cabinet body 1 during operation.

[0044] Furthermore, the inner wall of the sleeve block 713 is threadedly connected to the outer wall of the bidirectional threaded rod 712, and the bottom of the sleeve block 713 is connected to one end of the rotating block 714 through a hinged connection. Through this arrangement, the bidirectional threaded rod 712 can be rotated to cause the sleeve block 713 to move on its outer wall.

[0045] Furthermore, there are two clamping plates 7212 , which are equal in size and symmetrically distributed along the center plane of the grounding switch body 7216 . With this arrangement, the grounding switch body 7216 can be easily clamped and fixed by the two clamping plates 7212 .

[0046] Furthermore, the outer wall of the moving block 728 is matched with the inner wall of the rectangular groove 723 . Through this arrangement, the moving block 728 can slide on the inner wall of the rectangular groove 723 .

[0047] In addition, the outer wall of the extrusion rod 7215 is matched with the inner wall of the sleeve 7213. Through this arrangement, the extrusion rod 7215 can slide on the inner wall of the sleeve 7213 easily.

[0048] Working principle: When the grounding switch body 7216 needs to be locked, the operator can place the grounding switch body 7216 on the top of the support plate 722, and then close the cylinder 7211, causing the output end of the cylinder 7211 to contract, causing the side plate 729 to move. When the side plate 729 moves, it will move with the moving block 728 and the clamping plate 7212. During the movement of the moving block 728, the movable plate 727 will be rotated through the hinge. During the rotation of the movable plate 727, the fixed column 726 will cause the rotating plate 725 to rotate around the rotating rod 724. , prompting the other moving block 728 and the clamping plate 7212 to move, so that the two clamping plates 7212 are close to the grounding switch body 7216. After the two clamping plates 7212 are close to the grounding switch body 7216, the outer wall of the grounding switch body 7216 will squeeze the squeezing rod 7215, prompting the squeezing rod 7215 to squeeze the connecting spring 7214. Under the reaction of the connecting spring 7214, the squeezing rod 7215 will clamp and fix the grounding switch body 7216, so as to improve the stability of the grounding switch body 7216 during operation. When the body 7216 is working inside the electrical switch cabinet body 1, the operator can start the motor 1 711 and the motor 2 716 to cause the motor 1 711 to rotate with the bidirectional threaded rod 712. During the rotation of the bidirectional threaded rod 712, the two sleeve blocks 713 will move. When the two sleeve blocks 713 are relatively close to each other, the rotating block 714 will be rotated through the hinge. After the motor 2 716 is started, the output shaft 717 will rotate to cause the heat dissipation blades 718 to rotate. After the rotating block 714 rotates, the motor 2 716 is rotated, so that the The heat dissipation position of the heat dissipation blade 718 is now changed, thereby improving the heat dissipation effect inside the electrical switch cabinet body 1, and dissipating the heat for the grounding switch body 7216 to improve the stability of the grounding switch body 7216 during operation. During the rotation of the rotating block 714, the bottom plate 715 is prompted to move up and down. During the up and down movement of the bottom plate 715, the dust removal brush 7110 is moved up and down through the connecting plate 719, so that the dust removal brush 7110 can clean the dust on the inner wall of the electrical switch cabinet body 1, thereby improving the working effect inside the electrical switch cabinet body 1.
