rubber pads 1 are bonded at corners of the outer wall of the shell 3, and anti-skid grains are arranged on the outer wall of each rubber pad 1;

specifically, as shown in fig. 1 and 3, the baffle 12 of the device can block the through slot 13 when moving below the through slot, so that the housing 3 forms a closed space to protect the internal components.

A placing plate 9 is arranged on the inner wall of the shell 3, two supporting tables 21 are arranged at the top end of the placing plate 9, a warning lamp 4 is arranged at the top end of one supporting table 21 at one side of the top end of the placing plate 9 through a bolt, and a buzzer 10 is arranged at the top end of the other supporting table 21 at the other side of the top end of the placing plate 9 through a bolt;

the through grooves 13 are distributed in central symmetry about the center of the top end of the shell 3, and the centers of the warning lamp 4 and the buzzer 10 are respectively positioned on the same vertical line with the centers of the two through grooves 13;

specifically, as shown in fig. 1, when in use, the top ends of the warning light 4 and the buzzer 10 can pass through the through slot 13 to be exposed outside the housing 3, so that the warning light and the buzzer can transmit light and sound conveniently.

Two connecting rods 8 are fixed at one end of the bottom end of the placing plate 9, a fixing plate 7 is fixed at the bottom end of each connecting rod 8, a controller 5 is installed on one side of the bottom end inside the shell 3, a servo motor 6 is installed at the middle position of the bottom end inside the shell 3 through a bolt, an active rotating rod 20 is installed at the output end of the servo motor 6, and an active bevel gear 18 is installed inside the active rotating rod 20, penetrates through the inside of the fixing plate 7 and extends to the mounting box 17;

external threads are arranged on the outer walls of the driven rotating rod 14 and the driving rotating rod 20, and internal threads matched with the driven rotating rod 14 and the driving rotating rod 20 are arranged on the inner walls of the first moving block 11 and the fixed plate 7 respectively;

a guide groove is vertically formed in the inner wall of the shell 3, guide blocks are arranged on two sides of the placing plate 9, and the placing plate 9 is in sliding connection with the shell 3 through sliding fit between the guide blocks and the guide groove;

the size of the driving bevel gear 18 is smaller than that of the driven bevel gear 19, and the driving bevel gear 18 and the driven bevel gear 19 are meshed with each other;

specifically, as shown in fig. 1 and 2, when corona abnormality is detected, the servo motor 6 drives the driving rotating rod 20 to rotate, so that the fixed plate 7 pushes the placing plate 9 to move upwards, and simultaneously, the driving rotating rod 20 rotates to drive the driven rotating rod 14 to rotate through the cooperation of the driving bevel gear 18 and the driven bevel gear 19, so that the two first moving blocks 11 move towards each other and apply force to the baffle plate 12, so that the baffle plate 12 moves along with the cooperation of the second moving block 15 and the fixed rod 16, so that the through groove 13 is not shielded any more, and along with the continuous upward movement of the placing plate 9, the warning lamp 4 and the buzzer 10 on the placing plate 9 can finally pass through the baffle plate 12 to move to the outer side of the housing 3, and work better.

The working principle is as follows: when the device is used, firstly, the corona detector 2 is used for carrying out corona detection, when abnormity is detected, the signal is sent to the controller 5, the controller 5 controls the warning lamp 4 to be lightened, and controls the active rotating rod 20 to buzz, and simultaneously controls the servo motor 6 to be started, so that the servo motor 6 drives the active rotating rod 20 to rotate, and as the fixed plate 7 is connected with the placing plate 9 through the connecting rod 8, and the placing plate 9 is in sliding connection with the shell 3, the fixed plate 7 cannot rotate along with the active rotating rod 20 and can only move in the vertical direction and push the placing plate 9 to move upwards;

meanwhile, the driven rotating rod 14 is driven to rotate by the rotation of the driving rotating rod 20 through the matching of the driving bevel gear 18 and the driven bevel gear 19, so that the two first moving blocks 11 move oppositely and apply force to the baffle plate 12, the baffle plate 12 moves with the help of the matching of the second moving block 15 and the fixed rod 16, the through groove 13 is not blocked, the warning lamp 4 and the buzzer 10 on the plate 9 can penetrate through the baffle plate 12 to move to the outer side of the shell 3 along with the continuous upward movement of the plate 9, and the working is better performed.
