Background
With the gradual improvement of the power grid in the city, the electric wires are erected all over the streets and the alleys in the city, and the electric wires are weak because the electric wires are generally erected in the air in the use process.
Some plants in the city are called greening, but trees in the off-line tree crown or line corridor threatening the safe operation of the power supply line are called tree barriers. The tree barrier is used for influencing the safe operation of the power supply line in reality, tripping is performed if the tree barrier is used, and the lead is broken or the tower collapses if the tree barrier is used, so that the power failure of a large area is caused. Along with the annual increase of the density of the power grid, the contradiction between the branches and the power supply line is increasingly prominent, the influence of the branches on the power supply line is increasingly increased, and the direct economic loss caused by tree obstacles is increasingly large every year.
However, trees are growing all the time and workers cannot perform cyclic cleaning all the time, so cleaning is generally performed at intervals. In the cleaning process, due to the growth of trees, tree branches are easy to shield electric wires or directly contact the electric wires, workers generally directly adopt electric saws to clean the electric wires, and in the cleaning process, due to the shielding of the tree branches on the electric wires, the workers have to pay attention to the cleaning work of wings, so that the working time is increased; the long-time handheld electric saw can make the staff produce tired out, takes place the electric saw easily and touches the condition of electric wire.

As a further improvement of the invention, the outer surface of the wheel is provided with insections.
As a further improvement of the invention, the inner wall of the groove of the clamping rod is provided with an insulating layer.
The invention has the following remarkable beneficial effects:
1. the power supply line obstacle clearing device comprises a clamping rod and an expansion plate, wherein a groove used for clamping a wire is formed in the clamping rod, and an elastic sheet in the groove is used for fixing the wire in one step; the expansion plate rotates to be connected at the surface of centre gripping rod, and the quantity of expansion plate is three at least, and the even ring cloth of expansion plate is at the centre gripping rod surface, and the rotation of expansion plate is connected and can be made the expansion plate be fan-shaped and open. According to the invention, the clamping roller is moved to drive the fan-shaped expansion plate to move, and after the expansion plate touches the tree barriers, the tree barriers can be dispersed along the fan-shaped expansion plate as the clamping roller moves forward, so that the dispersion of the tree barriers can be far away from the electric wire, and workers can conveniently clean the tree barriers around the electric wire; the electric wire is kept away from gradually through the effect of expansion board to the barrier of trees for the electric wire clearly shows in the front of the staff, and effectual solution is cleared up the in-process trees and is produced the problem of sheltering from to the electric wire at the staff.
2. Because the clearance of barrier is generally gone on aloft, and the staff operation is not as nimble on ground, so expand the board front end and rotate through first torsional spring with centre gripping rod front end surface and be connected, through the characteristic of torsional spring, expand the board automatic under the effect of first torsional spring and form the contained angle of certain degree with centre gripping rod surface, make things convenient for the staff to remove and need not hand expansion board the centre gripping rod.
3. Because the expansion plate is rotationally connected with the clamping rod through the first torsion spring, the annular hoop is sleeved on the outer side of the expansion plate, and the annular hoop is sleeved on the outer surface of the expansion plate to bind the expansion plate so as to be convenient to carry; because the centre gripping rod is the joint on the electric wire, so be provided with the breach on the annular hoop, the setting of breach can make things convenient for the annular hoop to pass the electric wire and tie expansion plate.
4. The peripheral barrier of tree of electric wire has big or small, and the elasticity of first torsional spring is less, expand the board because the hindrance can laminate with the centre gripping rod gradually after meetting big barrier of tree again, lose the dispersion to the barrier of tree, so be provided with the draw-in groove at expansion inboard surface, the position that corresponds expansion board on the centre gripping rod is provided with the screens piece, the butt through screens piece top and draw-in groove forms stable holding power to expansion board after expansion board is opened, make expansion board can not change after meetting big barrier of tree yet.
5. Under the abutting action of the clamping pieces on the expansion plates, the expansion plates obtain stable supporting force, but in the actual use process, due to the number of the expansion plates, a worker moves the clamping pieces one by one to abut against the expansion plates, so that the working efficiency is reduced, the clamping pieces are rotatably connected with the clamping rods through the second torsion springs, and the top ends of the clamping pieces face the front ends of the clamping rods; because the screens piece sets up between expansion board and centre gripping rod, so open the back at the expansion board, the screens piece top and expansion board internal surface butt are slowly bouncing under the effect of second torsional spring, until with the draw-in groove butt, form stable holding power to the expansion board, reduced the removal of staff to the screens piece, improved work efficiency.
6. In the in-process that trees are grown, thick branch can directly produce the contact with the electric wire, and the front end of centre gripping rod is the plane, can push branch forward after the branch is touch to centre gripping rod front end, branch promotes forward can produce backward elasticity, rebound branch can cause frightening to lead to misoperation to the staff, so the ring of opening a way that has the loudspeaker form has been cup jointed at centre gripping rod front end, ring heavy-calibre one end of opening a way is equipped with the breach towards centre gripping rod and higher authority, the breach on the ring of opening a way can conveniently cup joint on the electric wire with the centre gripping rod together, the ring small-calibre of opening a way can make the branch slowly leave the electric wire along the inclined plane of the ring of opening a way for the front end, the branch can keep away from the electric wire gradually through the expansion board along with the advancing of centre gripping rod, make things convenient for the staff to clear up tree.
7. In the process of cleaning the tree obstacle, workers are generally far away from the ground, and the operable space is small, so that after the tree obstacle cleaning work is completed, the workers need to waste time and labor to accommodate the fan-shaped expansion plates; the take-up motor arranged at the tail end of the clamping rod is connected with the tail end of the expansion plate through a wire, the take-up motor is electrically connected with the battery, and the take-up motor is powered by the battery to roll up the wire, so that the expansion plate is conveniently accommodated.
8.

9. Because the surface of the wire is smooth, the outer surface of the wheel is provided with the insections to increase the friction force between the wheel and the wire.
10. With the increase of the service life of the electric wire, the surface of the electric wire is inevitably damaged, the electric wire is easy to leak electricity when being contacted with the clamping rod after being damaged, and therefore, the insulating layer is arranged in the groove of the clamping rod to prevent the electric wire from leaking electricity.
