On the top of one side, the second side wall 2-2 is located on the top of the other side of the insulating rod 1-1.

Both the first electric telescopic rod and the second electric telescopic rod are located between the first side wall 2-1 and the second side wall 2-2.

Wherein, the controller is a single-chip microcomputer, and its model is stc89c52. The Vcc terminal of the single-chip microcomputer is connected to the positive pole of the DC power supply, and its Vss terminal is connected to the negative pole of the DC power supply. The control terminal P0.1 of the 38th pin of the single-chip microcomputer is connected to the first electric telescopic The control end of the rod is connected, and the control end P0.2 of the 37th pin of the single-chip microcomputer is connected with the control end of the second electric telescopic rod. The single-chip microcomputer is wirelessly connected to the Internet through a wireless communication module. repeat.

Example 5 instructions for use:

When going out of the warehouse, the two driving levers are all located in the bracket between the first side wall 2-1 and the second side wall 2-2. The bracket can better protect the lever, the structural design is more reasonable, the structural strength is stronger, and the performance is more stable.

The server informs the single-chip microcomputer through the Internet and the wireless communication module, and the single-chip microcomputer informs the first electric telescopic rod, and the movable end of the first electric telescopic rod stretches and drives the first driving rod to extend above the bracket, that is, the first driving rod extends from the top of the bracket. out. Since the shape of the first driving rod matches the shape of the notch on the knife bar of the circuit breaker, the opening or closing operation of the circuit breaker can be realized by putting the first driving rod into the notch of the knife bar of the circuit breaker.

Since the notch on the cutter bar of the isolating switch is a ring, the shape of the first driving rod does not match the shape of the ring on the isolating switch, and the first driving rod cannot realize the opening or closing operation of the isolating switch.

Because the first driving lever can only operate the circuit breaker, but not the isolating switch, the possibility of misoperation is eliminated, and the accuracy of operation is improved.

The server informs the single-chip microcomputer through the Internet and the wireless communication module, and the single-chip microcomputer informs the first electric telescopic rod, and the movable end of the first electric telescopic rod shrinks and drives the first driving rod to retract in the bracket, that is, the first driving rod is retracted in the bracket. The server informs the single-chip microcomputer through the Internet and the wireless communication module, and the single-chip microcomputer informs the second electric telescopic rod, and the movable end of the second electric telescopic rod stretches and drives the second driving rod to extend above the bracket, that is, the second driving rod extends from the top of the bracket. out. Since the second driving rod is adapted to the shape of the ring on the isolating switch, inserting the second driving rod into the ring on the isolating switch can realize the opening or closing operation of the isolating switch.

Since the notch on the knife bar of the circuit breaker is a triangular notch, the shape of the second driving lever does not match the shape of the notch on the knife bar of the circuit breaker, and the second driving lever cannot realize the opening or closing operation of the isolating switch.

Because the second driving lever can only operate the isolating switch and cannot operate the circuit breaker, the possibility of misoperation is eliminated and the accuracy of operation is improved.

The utility model design of embodiment 5:

Two electric telescopic rods are installed on the top of the rod body, one electric telescopic rod drives one driving rod, and any driving rod is independently controlled by means of wireless communication. When in use, only one of the first driving lever and the second driving lever can be stretched out relative to the bracket at the front end of the rod body, and the stretched driving lever can only be operated correspondingly and in a limited way, which improves the operating efficiency. accuracy.
