Preferably, the method further comprises the step G: install the receiver on the pole, the position of adjustment receiver makes the balancing weight drop the back and falls in the receiver.
Preferably, when the 14# position of the electric wire is broken: the 14# portion of the electric wire was broken, and the left side of the broken point moved downward to the left and the right side moved downward to the right. The 10# pulling rope swings to the left along with the wires on the left side, and the 11# pulling rope swings to the right along with the wires on the right side. The swing arm of the 6# breaker moves to the left side, and the right arm presses the right spring downwards. The swing arm of the 7# breaker moves to the right side, and the left arm presses the left spring downwards. When the electric wire falls downwards, one of the two breakers is firstly disconnected with the tension rope, so that the tension rope is separated from the breaker, and the 6# breaker and the 4# tension rope are supposed to be firstly disconnected. The movable pulley moves downwards under the action of the gravity of the balancing weight. The 6# breaker and the 8#, 9# and 10# traction ropes are folded into the 1# pulley block along with the 3# tensioning rope. 7# breaker and 11#, 12#, 13# haulage rope draw in into the 2# assembly pulley along with 4#, 5# tensioning rope, and final electric wire hangs in the below of pole assembly pulley along with the haulage rope, and the balancing weight falls into in the receiver, prevents to drop.

When the electric wire falls downwards, one of the two breakers is firstly disconnected with the tension rope, so that the tension rope is separated from the breaker, and the 6# breaker and the 4# tension rope are supposed to be firstly disconnected. The movable pulley moves downwards under the action of the gravity of the balancing weight. The 6# breaker and the 8# and 10# traction ropes are folded into the 1# pulley block along with the 3# tensioning rope. The 7# breaker and the 11#, 12# and 13# traction ropes are folded into the 2# pulley block along with the 4# and 5# tensioning ropes. During furling, the 4# pulling rope is connected between the wire on the right side of the breaking point and the 3# tensioning rope. Because the tensile strength of haulage rope is less than the tensile strength of electric wire and tensioning rope, 9# haulage rope breaks off under the effect of balancing weight, and final electric wire hangs in the below of pole assembly pulley along with the haulage rope, and the balancing weight falls into in the receiver, prevents to drop.

The 10# pulling rope swings to the right along with the right wire. The swing arm of the 6# breaker moves to the right side, and the left arm presses the left spring downwards. The right-hand member of 3# tensioning rope takes place to break away from with the left couple of 6# breaker, makes the tensioning rope break away from. The movable pulley moves downwards under the action of the gravity of the balancing weight. The 8# traction rope is folded into the 1# pulley block along with the 3# tensioning rope. The 6# and 7# breakers and the 10#, 11#, 12# and 13# traction ropes are folded into the 2# pulley block along with the 4# and 5# tensioning ropes. During furling, the 9# pull cord was connected between the wire right of the break point and the 3# tension cord. Because the tensile strength of haulage rope is less than the tensile strength of electric wire and tensioning rope, 9# haulage rope breaks off under the effect of balancing weight, and final electric wire hangs in the below of pole assembly pulley along with the haulage rope, and the balancing weight falls into in the receiver, prevents to drop.
Preferably, when the tension rope breaks: assuming that the 4# tension rope breaks or breaks away from the breaker: the 8#, 9#, 10# haulage rope follows 3# tensioning rope and 6# breaker and draws in to 1# assembly pulley. The 11#, 12#, 13# pulling ropes are folded towards the 2# pulley block along with the 5# tensioning rope and the 7# breaker. Before being folded, the traction rope and the electric wire are in a connection state. In the folding process, the traction rope and the electric wire are in a sequentially tensioned state. Because the tensile strength of haulage rope is less than the tensile strength of electric wire and tensioning rope, the haulage rope is atress in proper order and is split under the effect of balancing weight, and final tensioning rope draws together into the assembly pulley of both sides with the breaker in, and the electric wire finally resumes normal condition.
Preferably, the sun-facing surface outside the breaker is provided with a solar panel, and the solar panel is electrically connected with the controller.
