[0024] Compared with the prior art, the implementation method for preventing wind deviation of high-voltage transmission lines provided by the present invention is as follows: before use, a plurality of barrier balls 100 are installed on the overhead line 720, and the overhead line 720 passes through the central tube 110 and is fixedly connected to the central tube 110, and the ball body 120 is sleeved on the central tube 110; a mover 200 is arranged on the ground, and is connected to the central tube 110 by a traction rope 230, and the state amplitude of the barrier ball 100 is reduced by means of the elastic reaction device 220; and a bearing member 400 and a support assembly 500 are installed at a position corresponding to the insulator 710 on the transmission line tower 700; when a large wind force acts on the overhead line 720, the overhead line 720 located between the two transmission line towers 700 shakes first, and under the action of the ball body 120, a safe distance is created between the two adjacent overhead lines 720; and the ball body 120 is arranged to have a self-rotation characteristic, so that when two ball bodies 120 are in contact or the ball body 120 is in contact with the overhead line 720, the contact condition is lighter. At the same time, due to the wind force, the insulator 710 rotates toward the transmission tower 700, and the pressure block 310 on the insulator 710 squeezes the pressure sensor 300. The pressure sensor 300 generates a signal and transmits it to the control unit of the driver 410. After analyzing and processing the signal, the control unit controls the driver 410 to drive the support assembly 500 to rotate to a horizontal state, and makes the two upper and lower limit members 600 act on the insulator 710 and the connection between the insulator 710 and the overhead line 720, thereby preventing the overhead line 720 from moving toward the transmission tower 700, thereby greatly improving the wind-proof effect of the overhead line 720.
[0025] See also Figures 1 to 3 As a specific implementation method of the high-voltage transmission line wind deflection prevention method provided by the present invention, a limiting flange 130 is provided at the center position of the central tube 110, and limiting stop bars 140 are provided at both ends; the outer diameter of the limiting flange 130 is the same as the outer diameter of the ball body 120, and the ball body 120 includes two hemispheres respectively installed on both sides of the annular flange, and the hemispheres are provided with rotating holes 150 that are rotatably connected to the outer side surface of the central tube 110; the ball body 120 is divided into two independent hemispheres, and they are respectively located on both sides of the limiting flange 130, so that the contact process of the hemispheres is more flexible.
[0026] The diameter of the limiting flange 130 is set to be equal to the diameter of the ball body 120 so that when two barrier balls 100 touch each other or the ball body 120 touches the overhead line 720 , the limiting flange 130 will not directly collide.
[0027] At the same time, limiting stop bars 140 are provided at both ends of the central tube 110 , and the hemisphere is provided between the limiting stop bars 140 and the limiting flange 130 , which can effectively prevent the hemisphere from falling off the central tube 110 .
[0028] As a specific implementation method of the wind deflection prevention method for high-voltage transmission lines provided by the present invention, a plurality of outwardly protruding convex plates are provided on the outer side of the hemisphere, and the plurality of convex plates are arranged in a spiral shape along the circumference of the hemisphere. With the aid of the spirally arranged convex plates, the hemisphere can be rotated more conveniently when subjected to wind force. At the same time, the outward extension of the flange also has a certain bird-repelling effect.
[0029] As a specific implementation method of the high-voltage transmission line wind deflection prevention method provided by the present invention, multiple blocking balls 100 on the same overhead line 720 are arranged at intervals and the blocking balls 100 on two adjacent overhead lines 720 correspond one to one or the blocking balls 100 on two adjacent overhead lines 720 are staggered.
[0030] The multiple barrier balls 100 on the same overhead line 720 are arranged at intervals and the barrier balls 100 on two adjacent overhead lines 720 correspond one to one, so that when two adjacent overhead lines 720 are approaching, the barrier effect produced by the two barrier balls 100 at corresponding positions can be better.
[0031] The multiple barrier balls 100 on the same overhead line 720 are arranged at intervals and the barrier balls 100 on two adjacent overhead lines 720 correspond one to one; in this way, the number of ball bodies 120 set on the overhead line 720 is reduced, making the installation of the barrier balls 100 quick and having less impact on the overhead line 720.

[0033] The plurality of elastic members 260 are arranged in a rectangular array at the bottom of the mounting groove 210 , and the sliding block 240 acts on the plurality of elastic members 260 with more uniform force, and the movement is more stable and quick.
[0034] Preferably, the elastic member 260 is a spring.
[0035] A groove is opened on the inner wall of the installation groove 210, and the displacement sensor 250 is installed in the groove. When the sliding block 240 slides in the installation groove 210, the displacement sensor 250 can monitor the moving distance of the sliding block 240, and then determine the shaking amplitude of the blocking ball 100.
[0036] When the displacement sensor 250 detects that the blocking ball 100 has a large shaking amplitude, the displacement sensor 250 can send a signal to the control unit of the controller. After analyzing and processing the signal, the control unit controls the driver 410 to drive the support assembly 500 to rotate to a working state.

[0044] See also Figure 1 , Figures 4 to 9 As a specific implementation method of the wind deflection prevention method for high-voltage transmission lines provided by the present invention, the lower limiter 600 is slidably connected to the lower side of the upper limiter 600, and the upper limiter 600 is provided with a second linear drive 610, and the free end of the second linear drive 610 is connected to the lower limiter 600; the lower limiter 600 is slidably connected to the outer surface of the upper limiter 600, and the second linear drive 610 is installed on the outer surface of the upper limiter 600, so starting the second linear drive 610 can control the movement of the lower limiter 600, thereby increasing the blocking range of the two limiters 600 to the insulator 710 and the overhead line 720.

With the help of the concave arc surface, the limiter 600 produces a semi-enclosed effect on the insulator 710, and the blocking effect is better.
