The beneficial effects of the present invention compared to the current technology are: The present invention, while in operation, rotates the torsion block, which in turn causes the lifting shaft to rotate in conjunction, which in turn causes the electrical connection block to move in conjunction. By connecting the connection wire and the external connection wire by the electric connection block, the first electromagnet in the ratchet mechanism at the lower end of the lifting shaft operates, so that the driven block is separated from the ratchet, and the ratchet idles, When the temperature in the connection space rises due to the overload of the bidirectional DC power control device, the heat conduction block raises the air pressure between the pressure block and the heat conduction block. In the direction, which causes the connecting spring to expand, compressing the moving spring and expansion spring, and moving the pneumatic block. Therefore, through the transmission of the first power transmission lever, the pressing lever is interlocked to move in the direction away from the bidirectional DC power control device, and thereby the lever is interlocked and rotated. When the temperature is not high and the generated temperature is maintained within the set value range, the rotary lever does not rotate 90 degrees due to the joint action of the connecting spring and the atmospheric pressure block, which separates the atmospheric pressure block and the thrust block. If the lever and push block are not in contact with each other, and this allows the device to be connected under a certain degree of overload, and the degree of overload is high and the temperature rises rapidly. , The gas pressure between the pressure block and the heat conduction block is rapidly increased, which causes the pressure block to move away from the heat conduction block. When moving, the rotary lever rotates 90 degrees, which causes the thrust block to return to its original position under the action of the connecting spring and separates the thrust block and the atmospheric pressure block. Under the action, it moves in the direction away from the center of the connection space, thereby interlocking the lever to increase the rotation angle, which pushes the push block downward, and the hydraulic mechanism moves the second hydraulic lever. The driving gears are rotated in conjunction with each other so that the fourth bevel gear, the drive shaft, the power transmission shaft, the second bevel gear, and the first bevel gear are interlocked and rotated. By this, the driven shaft is interlocked and rotated, and the rotation of the belt shaft is interlocked by the power transmission of the first pulley and the second pulley, and thereby the cam is interlocked and rotated, whereby the protruding block is rotated. The ratchet mechanism is moved by the rotation of the driven shaft when the projecting block is moved by moving the hooks in a direction away from the lifting shaft by interlocking them with each other, thereby separating the outer connecting wire and the connecting wire from the electric connecting block. The rotation is interlocked, whereby the rotation of the ratchet block is interlocked, and the lifting shaft is interlocked by the power transmission between the ratchet and the driven block to rotate in the opposite direction, thereby raising the electrical connection block and the external connection wire. When disconnecting the connection wire, disconnecting the connection, and causing a failure in the bidirectional DC power control device, a spark is generated and when a light emission signal arrives at the sensor, the drive motor is operated, the rotary shaft and the fifth umbrella The gear, the sixth bevel gear, and the spiral shaft are interlocked with each other to rotate, which interlocks the spiral block to move in the direction away from the drive motor. , This causes the slide bar to move in the direction away from the drive motor by interlocking with each other, thereby interlocking the atmospheric pressure block to move according to the above-described high temperature motion method, thereby turning off the power again, and the structure of the device is changed. Easy and convenient to operate, a slight overload does not result in a sudden power off, but immediately when a spark occurs or the set temperature is exceeded, power off immediately and continue working under the overload. It enables it and guarantees a quick protection process after a failure occurs.

Specific usage method: The present invention operates to rotate the torsion block 65, which in turn causes the lifting shaft 64 to rotate in an interlocking manner, which causes the electrical connection block 63 to interlock and lower, thereby causing the electrical connection block to rotate. The connecting wire 60 and the external connecting wire are connected by 63, and the first electromagnet 92 in the ratchet mechanism 88 at the lower end of the lifting shaft 64 is actuated, which causes the driven block 45 to be separated from the ratchet 48, and the ratchet 50 is set.

When the overload degree of the control device 58 is not high and the generated temperature is maintained within the set value range, the rotary lever 79 does not rotate 90 degrees by the joint action of the connection spring 22 and the atmospheric pressure block 21, As a result, the atmospheric pressure block 21 and the thrust block 83 are not separated from each other, so that the lever 34 and the push block 7 are not in contact with each other, thereby realizing the connection under a certain overload of the device, When the degree of overload is high and the temperature is rapidly rising, the gas pressure between the pressure block 21 and the heat conduction block 23 is rapidly increased, which causes the pressure block 21 to conduct heat. When moving in the direction away from the block 23, the rotary lever 79 rotates 90 degrees, which causes the thrust block 83 to return to its original position under the action of the connection spring 22, and the thrust block 83 and the atmospheric pressure block 21 to move. As a result, the atmospheric pressure block 21 moves under the action of atmospheric pressure in the direction away from the center of the connection space 72, thereby interlocking the lever 34 and increasing the rotation angle, thereby pushing downward. The block 7 is pushed and moved, and the second hydraulic lever 36 is interlocked and raised by the hydraulic mechanism 47, whereby the drive gear 57 is interlocked and rotated, whereby the fourth bevel gear 56, the drive shaft 37, and The power transmission shaft 39, the second bevel gear 40, and the first bevel gear 51 are interlocked and rotated, whereby the driven shaft 49 is interlocked and rotated, and the power is transmitted between the first pulley 53 and the second pulley 46. By interlocking the rotation of the belt shaft 52, As a result, the cam 54 is interlocked and rotated, whereby the protrusion block 4 is interlocked and moved in a direction away from the elevating shaft 64, thereby separating the external connection wire and the connection wire 60 from the electrical connection block 63, When the protruding block 4 is in motion, the rotation of the driven shaft 49 causes the rotation of the ratchet mechanism 88 to interlock, which causes the rotation of the ratchet block 51 to interlock, and the ratchet 50 and the driven block 45 transmit power to raise and lower the shaft. When 64 is interlocked and rotated in the opposite direction, which raises the electric connection block 63 to separate it from the external connection wire and the connection wire 60, disconnects the connection, and when the bidirectional DC power control device 58 fails, When a spark is generated and a light emission signal arrives at the sensor 59, the drive motor 27 is operated and the rotary shaft 26, the fifth bevel gear 25, the sixth bevel gear 24 and the spiral shaft 13 are linked. The spiral block 17 is interlocked and moved in the direction away from the drive motor 27, whereby the slide bar 15 is interlocked and moved in the direction away from the drive motor 27. In conjunction with the above, it is operated by the above-mentioned high temperature motion method, so that the power is turned off again, the structure of the device is simple, the operation is convenient, and a slight overload does not cause a sudden power off, When a spark occurs or the set temperature is exceeded, the power is turned off immediately, allowing to continue working under overload and guaranteeing a quick protection process after a failure occurs.
