[0015] A safety protection method for power maintenance, using any of the above power maintenance safety protectors, includes: installation, installing the other ends of the installation base plate and the support frame inside the power distribution box; Detection: In the initial state, the baffle and the protection device form a closed space to protect the protector, preventing the power detection element inside the protector from being accidentally triggered by electromagnetic interference. The power detection element inside the protector detects the power system. When a fault occurs in the power system, the fault generator is activated to close the circuit breaker and transmit an electrical signal to the control center. While controlling the alarm to give an early warning, the control center controls the rotation drive assembly to start, pushing out the protection device so that it no longer blocks the protector and exposing the faulty power connection. During the movement of the protection device, the pressing plate gradually moves down to fix the power connection at the output end of the protector. Cooling: When the protection device no longer blocks the faulty circuit, the drive device and the auxiliary device cooperate to cool the power connection, preventing the power connection from continuously heating up and catching fire due to overheating during a power system fault. The pressing plate fixes the power connection at the output end of the protector, preventing subsequent difficulties for workers in troubleshooting the faulty circuit after disassembling the protector, improving the protection effect of the device on the power system and facilitating user operation.

[0016] Beneficial effects 1. For this power maintenance safety protector and safety protection method, by activating the drive device, several protectors and several power connections are exposed. The protectors and power connections are exposed to the external environment, improving the ventilation of the protectors, reducing the temperature of some faulty power connections, preventing the power connections from continuously heating up and catching fire due to overheating during a power system fault, improving the protection effect of the device, and facilitating user operation.

[0017] 2. For this power maintenance safety protector and safety protection method, by activating the protection device, the device drives the circuit breaker to close as the protection device moves. Thus, the device can automatically cut off the power when the fault generator itself fails to disconnect the power, preventing the continuous transmission of electricity during a power system fault and avoiding the situation of short - circuit, improving the protection effect of the device on the power system. When the protection device moves to the maximum distance, the pressing plate presses and fixes several power connections at the bottom output end of the protector. At this time, the fixation of the pressing plate prevents the power connections from being scattered and mixed, making it difficult to quickly separate them when workers disassemble and repair the protector according to the alarm warning, improving the protection effect of the device on the power system and facilitating user operation.

[0018] 3. For this power maintenance safety protector and safety protection method, by activating the auxiliary device, the device cools the exposed protectors and power connections, preventing the power connections from continuously heating up and catching fire due to overheating during a power system fault, improving the protection effect of the device on the power system and facilitating user operation.

The power detection components inside the protector 10 detect the power system.

[0031] Working principle: Installation, installing the other ends of the installation base plate 1 and the support frame 30 inside the power distribution box; Detection: In the initial state, the baffle 13 and the protection device 4 form a closed space. At this time, the conductive cloth on the outer surfaces of the baffle 13 and the protection device 4 prevents the power detection element inside the protector 10 from being mis-triggered by electromagnetic interference. During this period, the first gear disk 32 and the third gear disk 520 do not contact each other, and the latch 320 is clamped inside the connecting rod 331. The power detection element inside the protector 10 detects the power system. When a fault occurs in the power system, the fault generator is activated to close the circuit breaker switch 11 and transmit an electrical signal to the control center. While controlling the alarm to give an early warning, the control center activates the rotary drive assembly 31. The activation of the rotary drive assembly 31 drives the rotating shaft 310 to rotate. The rotation of the rotating shaft 310 drives the linear drive assembly 311 to rotate. The rotation of the linear drive assembly 311 drives the output rod 312, the latch 320, and the connecting rod 331 to rotate. The rotation of the connecting rod 331 drives the first movable wheel 330 to rotate. The rotation of the first movable wheel 330 drives the second movable wheel 340 to rotate through the movable belt. The rotation of the second movable wheel 340 drives the first screw rod 341 to rotate. The rotation of the first screw rod 341 drives the left side through rod 36 to move forward. The slide bar 360 is used to limit the movement of the through rod 36. The movement of the left side through rod 36 drives the protection device 4 to move forward through the left side side plate 361. The right side through rod 36 and the limiting rod 37 are used to limit the moving direction of the protection device 4. After the protection device 4 moves, it no longer blocks the protector 10. At this time, the movement of the protection device 4 exposes several protectors 10 and several power connection wires 12. The exposure of the protectors 10 and the power connection wires 12 to the external environment improves the ventilation of the protectors 10, reduces the temperature of a part of the faulty power connection wires 12, and avoids the situation where the power connection wires 12 continuously heat up and catch fire due to overheating caused by a power system fault, improving the protection effect of the device and facilitating user use; In the above steps, the movement of the protection device 4 drives the second gear disc 420 to move on the top of the toothed plate 14. While the second gear disc 420 moves on the top of the toothed plate 14, it rotates itself. The rotation of the second gear disc 420 drives the fourth moving wheel 421 to rotate through the third shaft rod 42. The rotation of the fourth moving wheel 421 drives the third moving wheel 400 to rotate through the second moving belt 43. The rotation of the third moving wheel 400 drives the second shaft rod 40 to rotate. The rotation of the second shaft rod 40 drives the first bevel gear 41 to move. The movement of the first bevel gear 41 drives the second bevel gear 441 to rotate. The rotation of the second bevel gear 441 drives the fixed rod 442 and the second screw rod 443 to rotate. The rotation of the second screw rod 443 drives the push rod 45 to move downward. The movement of the push rod 45 drives the pressure plate 450 to move downward. During the movement of the protection device 4, if the fault generator has a heat fault and cannot drive the circuit breaker switch 11 to close, at this time, the pressure plate 450 continuously moves downward under the continuous movement of the protection device 4. When the pressure plate 450 moves downward, it moves against the circuit breaker switch 11 and drives the circuit breaker switch 11 to close as the protection device 4 moves. Thus, the device can automatically cut off the power supply when the fault generator fails to cut off the power supply by itself, avoiding the situation of continuous power transmission in the power system failure, which may lead to a short circuit, and improving the protection effect of the device on the power system. When the protection device 4 moves to the maximum distance, the pressure plate 450 presses and fixes several power connection wires 12 at the bottom output end of the protector 10. At this time, the fixing of the pressure plate 450 avoids the situation that the power connection wires 12 are scattered and mixed and difficult to quickly separate when the staff disassemble and repair the protector 10 under the alarm warning, improving the protection effect of the device on the power system and facilitating the user to use; Cool down. When the protection device 4 no longer blocks the faulty line, the control center controls the linear drive assembly 311 to start. When the linear drive assembly 311 starts, the output rod 312 is retracted and moved backward. At this time, the clamping rod 320 moves out from the connecting rod 331, and the first gear disk 32 meshes with the third gear disk 520. At this time, the rotation drive assembly 31 continues to drive the rotating shaft 310 to rotate. At this time, the rotation of the rotating shaft 310 drives the third gear disk 520 to rotate through the linear drive assembly 311, the output rod 312, and the first gear disk 32. The rotation of the third gear disk 520 drives the two fourth gear disks 530 to rotate. The rotation of the third gear disk 520 and the two fourth gear disks 530 drives the three output shafts 54 to rotate. The rotation of the output shaft 54 drives the fan blades 540 to rotate. Since the number of teeth of the first gear disk 32 is greater than the number of teeth of the third gear disk 520, and the number of teeth of the third gear disk 520 is greater than the number of teeth of the fourth gear disk 530, that is, when the first gear disk 32 rotates one circle, it drives the third gear disk 520 to rotate several circles, and the rotation of the third gear disk 520 several circles drives the fourth gear disk 530 to rotate several circles, ensuring that the fan blades 540 can normally blow out wind from the blowing head 50. The wind blown out by the blowing head 50 is guided by the guide plate 51 to blow to several protectors 10 and power connection wires 12 exposed by the protection assembly for cooling, avoiding the situation that the power connection wire 12 continuously heats up and catches fire due to overheating in the power system failure, improving the protection effect of the device on the power system, and facilitating the use of users.
