[0038] Referring to Figures 1 to 4 , the protective plate maintenance isolation device according to the embodiment of the present utility model includes:
[0039] A base 100, the base 100 has an outer side surface and an inner side surface, and the base 100 is used to be connected to the area of the cabinet body 400 corresponding to a plurality of protective plates 500 through the inner side surface;
[0040] A dedicated unlocking key and a plurality of protective covers 200, and the plurality of protective covers 200 are all detachably connected to the outer side surface of the base 100. The plurality of protective covers 200 are respectively used to cover a plurality of protective pressure plates 500. The dedicated unlocking key is used to detach the protective cover 200 from the connection with the base 100, so that the protective cover 200 can move away from the base 100 from the inside to the outside, and the protective cover 200 can move closer to the base 100 from the outside to the inside, so that the protective cover 200 is automatically connected to the outer side surface of the base 100.
[0041] It can be understood that the base 100 is connected to the area of the electric cabinet body 400 corresponding to the plurality of protective pressure plates 500. Before the maintenance personnel perform maintenance on the power system, the maintenance personnel can connect the plurality of protective covers 200 to the base 100, so that the plurality of protective covers 200 respectively cover the plurality of protective pressure plates 500, and then the plurality of protective pressure plates 500 are respectively inside the plurality of protective covers 200, ensuring that the protective pressure plates 500 can be isolated by the protective covers 200. After the maintenance personnel connect the plurality of protective covers 200 to the base 100, they can start to maintain the power system. During the maintenance process of the maintenance personnel, the protective cover 200 plays an isolation and protection role for the protective pressure plate 500, effectively preventing the maintenance personnel from accidentally touching or accidentally moving the protective pressure plate 500 during the maintenance process, and further preventing the normally operating equipment from tripping due to the accidental touch or accidental movement of the protective pressure plate 500, reducing the possibility of the power equipment tripping due to the accidental touch of the maintenance personnel, and further effectively preventing the occurrence of misoperation accidents.
[0042] On the other hand, in the embodiment of the present invention, the disassembly of the protective cover 200 requires a specific dedicated unlocking key, which avoids the disassembly of the protective cover 200 by irrelevant personnel, and further avoids the occurrence of misoperation accidents.
[0043] On the other hand, referring to Figure 1 , the inside-outside direction is the front-back direction in the figure. The inner side surface of the base 100 is the front side surface of the base 100, and the outer side surface of the base 100 is the rear side surface of the base 100.
[0044] Referring to Figures 7 to 9, the maintenance isolation device for the protection pressure plate further includes a plurality of magnetic snap components 300, and the plurality of protective covers 200 are respectively detachably connected to the base 100 through the plurality of magnetic snap components 300. Specifically, a plurality of positioning holes 110 are formed on the outer side surface of the base 100. The plurality of magnetic snap components 300 each include a magnetic snap lock 310 and a locking pin 320. The plurality of magnetic snap locks 310 are respectively arranged on the plurality of protective covers 200, and the plurality of locking pins 320 are respectively fixed in the plurality of positioning holes 110. The pin of the locking pin 320 is parallel to the inside-outside direction. The magnetic snap lock 310 can be inserted into the positioning hole 110 so that the pin of the locking pin 320 is inserted into the connection hole of the magnetic snap lock 310, and the magnetic snap lock 310 and the locking pin 320 are connected to each other. The special unlocking key is a magnetic unlocking key, and the magnetic unlocking key is used to magnetically attract the magnetic snap lock 310 so that the magnetic snap lock 310 is disengaged from the connection with the locking pin 320.
[0045] In the present utility model, the magnetic snap component 300 is also referred to as a magnetic control snap component, similar to the anti-theft magnetic snap used on clothing, shoes and hats. The magnetic snap lock 310 generally includes a locking magnet and a mechanical buckle, and the locking pin 320 includes a base and a pin. The pin is connected to the base. The locking magnet is generally a neodymium iron boron locking magnet. When it is necessary to install the protective cover 200 on the base 100, the maintenance personnel can align the magnetic snap lock 310 on the protective cover 200 with the corresponding locking pin 320 on the base 100, and then press the protective cover 200 from the outside to the inside, so that the pin of the locking pin 320 is inserted into the connection hole on the magnetic snap lock 310, thereby completing the installation of the protective cover 200. When the magnetic snap lock 310 and the locking pin 320 are in a magnetically snapped state, that is, when the magnetic snap lock 310 and the locking pin 320 are connected to each other, the mechanical buckle clamps the pin. At this time, the protective cover 200 can be firmly installed on the base 100. When it is necessary to disassemble the protective cover 200, the maintenance personnel can hold the magnetic unlocking key and approach the magnetic snap lock 310 on the protective cover 200, so that the magnetic unlocking key and the locking magnet in the magnetic snap lock 310 are magnetically attracted to each other. At this time, under the action of the locking magnet, the mechanical buckle moves in a direction away from the pin, so that the mechanical buckle releases the pin, and the maintenance personnel can take away the protective cover 200 from the inside to the outside to complete the disassembly of the protective cover 200. The magnetic hole snap component and the magnetic snap lock 310 and the locking pin 320 in the magnetic hole snap component are all common structures and will not be further described here.
[0046] The magnetic unlocking key can be a special magnetic rod. The magnetic unlocking key is a common accessory for unlocking the magnetic snap component 300 and will not be further described here. The disassembly of the protective cover 200 requires a specific magnetic unlocking key, which avoids the unauthorized disassembly of the protective cover 200 by irrelevant personnel, thereby avoiding the occurrence of misoperation accidents. The magnetic unlocking key can be a special magnetic rod.
[0047] In the embodiment of the present utility model, the number of the protective covers 200 is the same as that of the protection pressing plates 500. During the actual maintenance process, maintenance personnel can determine which protection pressing plates 500 need to be protected by the protective covers 200 according to the actual maintenance situation, and then flexibly adjust the installation position and the number of the protective covers 200. Warning slogans are written on the outer wall of the protective cover 200 to warn irrelevant personnel not to operate.
[0048] Reference Figures 5 to 8 , positioning posts 210 are provided on multiple protective covers 200. Multiple positioning posts 210 are all parallel to the inner and outer direction. First mounting holes 220 are formed in multiple positioning posts 210. Multiple magnetic snap locks 310 are respectively arranged in the multiple first mounting holes 220. The positioning posts 210 can be inserted into the positioning holes 110 so that the pin of the locking pin 320 is inserted into the connecting hole of the magnetic snap lock 310. It can be understood that when maintenance personnel need to install the protective cover 200, they can align the positioning posts 210 on the protective cover 200 with the corresponding positioning holes 110 on the base 100, and then insert the positioning posts 210 on the protective cover 200 into the positioning holes 110 on the base 100, so that the pin of the locking pin 320 is inserted into the connecting hole of the magnetic snap lock 310 to complete the installation of the protective cover 200. The inner walls of the positioning posts 210 and the positioning holes 110 play a positioning role in the installation of the protective cover 200, so that the protective cover 200 can be accurately installed on the base 100. In the embodiment of the present utility model, after the positioning posts 210 are inserted into the positioning holes 110, that is, after the protective cover 200 is installed on the base 100, the protective cover 200 abuts against the lower surface of the base 100. The protective cover 200 abuts against the lower surface of the base 100, so that the base 100 plays a limiting role on the protective cover 200, avoiding the protective cover 200 from swinging under its own gravity or external impact, and effectively avoiding the protective cover 200 from accidentally touching the protection pressing plate 500 due to external impact. The inner walls of the positioning posts 210 and the positioning holes 110 play a positioning and guiding role in the installation of the protective cover 200, improving the convenience for maintenance personnel to install the protective cover 200.
[0049] Reference Figure 6, the maintenance isolation device for protection pressure plates further includes a plurality of first magnetic members 130. The plurality of first magnetic members 130 are all arranged on the inner side surface of the base 100, and the plurality of first magnetic members 130 can all magnetically attract the cabinet body 400, so that the base 100 is connected to the cabinet body 400 through the plurality of first magnetic members 130. It can be understood that the first magnetic member 130 can be a first magnet, and the first magnet can magnetically attract the cabinet body 400, thereby fixing the base 100 on the cabinet body 400. Specifically, the number of the first magnetic members 130 is multiple, and a plurality of second installation holes 120 are formed on the inner side surface of the base 100, and the plurality of first magnetic members 130 are respectively arranged in the plurality of second installation holes 120. The first magnetic member 130 allows maintenance personnel to freely install the base 100 on the cabinet body 400 to adapt to different installation environments, so that the base 100 can cooperate with a plurality of protection pressure plates 500 on the cabinet body 400. And the first magnetic member 130 also allows maintenance personnel to disassemble the base 100 from the cabinet body 400, improving the convenience of installation and disassembly of the base 100.
[0050] Reference Figures 3 to 6 , a handle groove 140 is formed on the inner side surface of the base 100. It can be understood that the handle groove 140 can allow the fingers of maintenance personnel to extend out, so as to facilitate the maintenance personnel to grasp the base 100, improving the convenience of the maintenance personnel to install or carry the base 100. Specifically, there are two handle grooves 140.
[0051] As another embodiment of the present invention, the base 100 is adhered to the cabinet body 400 through the inner side surface. It can be understood that the base 100 can be adhered to the cabinet body 400 through glue, and an adhesive layer can also be provided on the base 100, and the base 100 is adhered to the cabinet body 400 through the adhesive layer. In the present invention, the base 100 is not only magnetically fixed to the cabinet body 400 through the first magnetic member 130, but also adhered to the cabinet body 400 through glue to improve the stability of the connection of the base 100. On the other hand, the base 100 can be adhered to the cabinet body 400 by pouring glue through the handle groove 140.
[0052] In the present invention, the base 100 is parallel to the left - right direction, a plurality of second installation holes 120 are distributed along the left - right direction, and a plurality of positioning holes 110 are distributed along the left - right direction. After the base 100 is installed on the cabinet body 400, the plurality of second installation holes 120 on the base 100 correspond to the plurality of protection pressure plates 500 one by one.
[0053] As an embodiment of the present utility model, the protective cover 200 is made of a transparent material. It can be understood that the protective cover 200 made of a transparent material allows maintenance personnel to see the position of the protection pressure plate 500 through the protective cover 200 during the installation process of the protective cover 200, so as to ensure that the protection pressure plate 500 is not accidentally touched during the installation process of the protective cover 200, improving the convenience of installation for maintenance personnel. Specifically, both the protective cover 200 and the base 100 are made of insulating acrylic material.
