A distribution switch body 3 is vertically slid in the moving groove 2, and a limiting component 4 is fixed at the rear end of the distribution switch body 3;

[0026] A control circuit board is fixedly connected to the outer wall of the distribution switch box 1. The distribution switch body 3 is electrically connected to the control circuit board.

[0027] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 5 shown, the limiting component 4 includes a driving bin 401 and a guide rod 402. The outer wall of the driving bin 401 is fixedly connected to the inner wall of the distribution switch box 1. Both ends of the guide rod 402 are fixedly connected to the side wall of the driving bin 401. A rotating cylinder 403 is sleeved on the outer wall of the guide rod 402. A motor is fixedly connected to the bottom end of the rotating cylinder 403, and the bottom end of the main shaft of the motor is rotatably connected to the rotating cylinder 403. And the main shaft of the motor is fixedly connected with a telescopic shaft 404. A rubber plug 405 is fixedly connected to the moving end of the telescopic shaft 404. The outer diameter of the rubber plug 405 matches the inner diameter of the rotating cylinder 403. Limiting blocks 406 are fixedly connected to both ends of the moving end of the telescopic shaft 404. A notch slidably matched with the limiting block 406 is opened in the inner wall of the rotating cylinder 403. Due to the setting of the rubber plug 405 inside the rotating cylinder 403, by filling or reducing the gas into the rotating cylinder 403, the rubber plug 405 can be moved up and down, so that the rubber plug 405 can move downwards and push the moving end of the telescopic shaft 404 downwards, and insert the limiting block 406 on the telescopic shaft 404 into the inside of the rotating sleeve 409;

[0028] In this embodiment, Figure 2 and Figure 3 shown, the rotating cylinder 403 includes a driving wheel 4031 and a straight tooth plate 4032. The inner side of the driving wheel 4031 is fixedly connected to the outer wall of the rotating cylinder 403. The side wall of the straight tooth plate 4032 is fixedly connected to the inner wall of the driving bin 401. The straight tooth plate 4032 is meshed with the driving wheel 4031. Start the motor, so that the motor drives the rotating cylinder 403 to rotate through the telescopic shaft 404. Due to the setting of the driving wheel 4031 and the straight tooth plate 4032, the whole motor and the rotating cylinder 403 move back and forth and are pushed to the rear end of the corresponding distribution switch body 3;

[0029] In this embodiment, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 6 , the limiting component 4 further includes a fixing sleeve 407. The side wall of the fixing sleeve 407 is fixedly connected to the rear end of the power distribution switch body 3. A driving screw rod 408 is threadedly connected inside the fixing sleeve 407. The bottom end of the driving screw rod 408 is rotatably connected to the inner wall of the driving chamber 401. A rotating sleeve 409 is fixed to the top end of the driving screw rod 408. A through groove that slidably cooperates with the limiting block 406 is formed inside the rotating sleeve 409. Along with one end of the telescopic shaft 404 being inserted into the rotating sleeve 409, at this time, by starting the motor, the motor drives the driving screw rod 408 to rotate through the rotating sleeve 409, so that through the setting of the fixing sleeve 407, the entire power distribution switch body 3 is driven to move downward, so that when a device fails, the corresponding power distribution switch is moved downward to facilitate the staff to observe and quickly locate the fault;

[0030] In this embodiment, as shown in Figure 1 , Figure 3 and Figure 7 , a connection port 5 is formed inside the power distribution switch body 3. A connection column 6 is horizontally arranged above the power distribution switch body 3. A limiting rod 7 is fixedly connected inside the inner wall of the connection column 6. A telescopic spring is fixedly connected to the rear end of the limiting rod 7. A limiting groove that matches the limiting rod is formed inside the inner wall of the connection port 5. A limiting sleeve 8 is sleeved on the top end of the connection column 6. A push rod 9 is fixedly connected inside the inner wall of the limiting sleeve 8.

The shaft sleeve 11 is rotatably connected to the telescopic shaft 404 through a bearing. Along with the horizontal movement of the motor, the connecting rod 10 is inserted into the rear end of the limiting sleeve 8 for limitation. At the same time, when the telescopic shaft 404 moves downward, through the setting of the shaft sleeve 11, the connecting rod 10 moves downward synchronously, pushing the limiting sleeve 8 to wrap the connection column 6, so that the limiting rod 7 is pushed out of the connection port 5 through the push rod 9, releasing the connection between the power distribution switch body 3 and the connection column 6, so that when a device fails, the circuit connection will be disconnected;

[0031] In this embodiment, as shown in Figure 1 and Figure 3 , a sliding groove 12 is horizontally formed on the outer wall of the power distribution switch box 1. The limiting sleeve 8 is slidably matched with the sliding groove 12, so that along with the up and down movement of the connecting rod 10, the limiting sleeve 8 can be pushed, so that the limiting sleeve 8 moves vertically to facilitate the disconnection of the connection structure between the power distribution switch body 3 and the connection column 6;

[0032] In this embodiment, as shown in Figure 1and Figure 7 As shown in the figure, the top end of the connecting column 6 is electrically connected to an external cable, and a current sensor 13 is electrically connected to the external cable. The current sensor 13 is electrically connected to the control circuit board. When the device is in use, through the settings of the current sensor 13 and the control circuit board, circuit monitoring can be carried out. When a device failure occurs, a signal can be obtained in a timely manner for operation feedback. The models of the current sensor and the control circuit board are HC5FW300-S / SP1 current sensor and C8051F020 single-chip microcomputer respectively;

[0033] In this embodiment, as Figure 1 shown, a cable storage compartment 14 is provided on the outer wall of the power distribution switch box 1. A number of through holes are provided on the side wall of the cable storage compartment 14, and the number of through holes is arranged vertically at equal intervals. Through the setting of the cable storage compartment 14, when the power distribution switch body 3 is installed, it is convenient to place and arrange the cables, preventing the lines from being messy and causing inconvenience in use.

[0034] The usage method and advantages of the present invention: The fire-proof power distribution switch device based on the function of accurate fault location works as follows:

[0035] As Figures 1 to 7 shown, when a circuit failure occurs in the power distribution switch body 3 in the power distribution switch box 1, the current sensor 13 will obtain the current circuit connection status. At this time, the current sensor 13 will transmit an electrical signal to the control circuit board. The control circuit board will receive the signal and feedback a corresponding electrical signal to start the motor. The motor will drive the rotating cylinder 403 to rotate through the telescopic shaft 404. Due to the settings of the driving wheel 4031 and the straight tooth plate 4032, the entire motor and the rotating cylinder 403 will move back and forth, and be pushed to the rear end of the corresponding power distribution switch body 3. At this time, through the setting of the connecting rod 10, along with the horizontal movement of the motor, the connecting rod 10 is inserted into the rear end of the limiting sleeve 8 for limitation. The models of the current sensor and the control circuit board are HC5FW300-S / SP1 current sensor and C8051F020 single-chip microcomputer respectively;

[0036] Then, due to the setting of the rubber plug 405 inside the rotating cylinder 403, gas can be filled or reduced into the rotating cylinder 403, causing the rubber plug 405 to move up and down. The rubber plug 405 can move downward, pushing the mobile end of the telescopic shaft 404 downward, and inserting the limiting block 406 on the telescopic shaft 404 into the inside of the rotating sleeve 409. At this time, due to the settings of the connecting rod 10 and the limiting sleeve 8, the connecting rod 10 moves downward synchronously, pushing the limiting sleeve 8 to wrap the connecting column 6, causing the limiting rod 7 to be pushed out of the connection port 5 through the push rod 9, releasing the connection between the power distribution switch body 3 and the connecting column 6, so that when a device failure occurs, the circuit connection will be disconnected;

[0037] As described above, along with the downward movement of the telescopic shaft 404, it is inserted into the rotating sleeve 409. At this time, by starting the motor, the motor drives the driving lead screw 408 to rotate through the rotating sleeve 409, so that through the setting of the fixed sleeve 407, the entire power distribution switch body 3 is driven to move downward, so that when a device failure occurs, the corresponding power distribution switch is moved downward to facilitate the observation by the staff and quickly locate the fault.
