[0002] Various types of protection devices in power production are equipped with protection plates, which are used for outlet tripping or closing switches, as well as related protection functions. The protection plates currently used are generally exposed and can be put in or out at will without an anti-misoperation cover. According to the patent document with the authorization announcement number of CN211743864U and the name of "Anti-misoperation device for relay protection plate", the housing is fixed by the fixing hole on the fixing plate, so that it can effectively prevent the phenomenon of being knocked down by humans during use, thereby further improving safety. When the staff is working, the protective cover is covered on the housing, and the fixing block is rotated so that the fixing block contacts the upper surface of the first connecting plate to fix the protective cover, and then the two cover plates are opened to expose the label on the groove, so as to remind people that work is being done here to prevent others from operating it. At the same time, the housing and the protective cover cover the protection plate, which can effectively prevent the staff from accidentally touching the protection plate when working and causing accidents, thereby improving safety. However, there are still the following defects:

[0003] A shell is provided for protection, but the shell is fixed by fixing holes. When the internal relay protection pressure plate needs to be replaced for repair, it is very inconvenient to open the protective cover for repair. At this time, the shell needs to be removed for easy repair. However, the device is not convenient for removing the shell, which makes repair more troublesome. Utility Model Content

[0024] Specifically, by Figure 2-4The adjusting mechanism 2 includes two U-shaped round rods 201 symmetrically fixed on the top of the bottom plate 1, and two protective boxes 3 are located between the two U-shaped round rods 201. A slide plate 206 is fixedly installed on the side of the two protective boxes 3 away from each other. The two slide plates 206 are movably sleeved on the outside of the two U-shaped round rods 201. A ring 203 is fixedly sleeved on the middle part of the outside of the U-shaped round rod 201. A spring 202 is fixedly connected between the two slide plates 206 and the ring 203. The two springs 202 are sleeved on the outside of the U-shaped round rod 201. A disk 208 is provided above the bottom plate 1. Two side rods 2016 are symmetrically fixedly installed on the outside of the disk 208. A roller 2013 is provided on the end of the two side rods 2016 away from each other. The two protective boxes 3 are fixed on the side close to the disk 208. A side plate 5 is fixedly installed, and two rollers 2013 are located between the two side plates 5. A vertical plate 205 is fixedly installed on the top of the bottom plate 1. The vertical plate 205 is located on the side of the disc 208 away from the two protection boxes 3. A transmission shaft 207 is fixedly installed on the side of the disc 208 away from the two protection boxes 3. The end of the transmission shaft 207 away from the disc 208 passes through the vertical plate 205 and is fixedly installed with a motor 2012, and the transmission shaft 207 is rotatably connected to the vertical plate 205. An L-shaped plate 204 is fixedly installed on the motor 2012. The L-shaped plate 204 is fixed on the side of the vertical plate 205 away from the disc 208. Support columns 2015 are fixedly installed on the side of the two side rods 2016 close to the vertical plate 205.

[0025] In the use state, in the initial state, each spring 202 is in a natural state, and the two protection boxes 3 fit each other to protect the relay protection pressure plate to prevent the staff from accidentally touching it. When the relay protection pressure plate needs to be repaired or replaced, first start the motor 2012 to drive the transmission shaft 207 to rotate, and drive the two side rods 2016 to rotate through the disc 208. At the same time, the two balls 2014 roll on the vertical plate 205 to limit the two side rods 2016 and ensure the stable rotation of the two side rods 2016. Then the two rollers 2013 roll on the two side plates 5 respectively, and push the two protection boxes 3 to move, so that the two protection boxes 3 are away from each other to expose the relay protection pressure plate. Finally, the relay protection pressure plate can be repaired or replaced.
