[0018] Reference Figure 3 - Figure 6 The buffer damping mechanism 4 includes a positioning plate 41, a positioning slide 42, an air cylinder 43, a piston 44, a connecting sleeve 45, an air inlet pipe 46, an air outlet pipe 47 and an adjusting component 48 for adjusting the air outlet volume. The positioning plate 41 is fixedly connected to one side of the outer wall of the adjusting plate 3. There are multiple air cylinders 43, and one side wall of the air cylinder 43 is fixedly connected to the positioning slide 42. A sliding groove for the sliding of the positioning slide 42 is provided on the positioning plate 41. The piston 44 is slidably connected to the inside of the air cylinder 43 and extends out of the air cylinder 43 and is fixedly connected to the connecting sleeve 45. The high-voltage wire runs through the inside of the connecting sleeve 45. The air inlet pipe 46 and the air outlet pipe 47 are respectively fixedly connected to both ends of the air cylinder 43, and a one-way valve is fixedly provided on the air inlet pipe 46 and the air outlet pipe 47. The adjusting component 48 is fixedly connected to the air cylinder 43.

[0019] Reference Figure 5 - Figure 6 The adjusting assembly 48 includes an air outlet top plate 481, a support rod 482, a first motor 483, a sealing cover 484, an abutment plate 485, an arc frame 486, a pressing plate 487 and a first switch 488. The air outlet top plate 481 is fixedly connected to the air outlet pipe 47, the support rod 482 is fixedly connected to the outer wall of the air outlet top plate 481, the first motor 483 is fixedly connected to one side of the outer wall of the support plate, the sealing cover 484 is rotatably connected to the other side of the outer wall of the support plate through a bearing, and the output end of the first motor 483 is fixedly connected to the sealing cover 484, the abutment plate 485 is fixedly connected to the center of one side of the sealing cover 484, the arc frame 486 is fixedly connected to the top of the air outlet top plate 481, the pressing plate 487 is rotatably connected to the arc frame 486 through a rotating shaft, the first switch 488 is fixedly connected to the arc frame 486, and the first switch 488 and the pressing plate 487 are both provided with a plurality of numbers and are evenly arranged along the circumferential direction of the arc frame 486.

[0020] In this embodiment, the device is first transferred to the location where it is to be used, and the entire device is fixed to the high-voltage pole to be used by a clamp. The adjusting plate 3 is pulled according to the length of the high-voltage line to be fixed, so that the adjusting plate 3 slides inside the fixing plate 2. After sliding to the required fixed height, the position of the adjusting plate 3 is locked, and the high-voltage line is fixed to the clamp and passes through the buffer damping mechanism 4 and the high-voltage line stabilizing mechanism 6 in sequence. When the high-voltage line swings, it drives the piston 44 to move in the air cylinder 43. The air in the cylinder is discharged through the air outlet pipe 47 and enters the air inlet pipe 46. Due to the viscous resistance of the air, the movement of the piston 44 is hindered, thereby generating a damping force. The damping force is related to the swing speed of the high-voltage line. The faster the swing speed, the greater the damping force, which can effectively suppress the rapid swing of the high-voltage line. By adjusting the size of the aperture of the air outlet pipe 47 and the initial air pressure in the air cylinder 43 through the adjustment component 48, the damping coefficient of the buffer damping mechanism 4 can be adjusted to adapt to different swinging conditions. When the wind speed increases, the swing amplitude and frequency of the high-voltage line will increase. In order to effectively suppress the excessive swing of the high-voltage line, it is necessary to increase the size of the air outlet aperture to speed up the air discharge speed in the air cylinder 43, thereby providing a greater damping force to buffer the movement of the high-voltage line. On the contrary, when the wind speed decreases, the swing of the high-voltage line is relatively weakened. The size of the throttle hole can be appropriately reduced to avoid excessive damping force causing unnecessary stress on the high-voltage line. Start the first motor 483 to drive the sealing cover 484 to rotate. During the rotation, the abutment plate 485 abuts the pressing plate 487, driving the pressing plate 487 to rotate so that the pressing plate 487 abuts the first switch 488. Different first switches 488 represent different rotation angles of the sealing cover 484. Different rotation angles represent different sizes of air outlet apertures. The adjustment component 48 can be linked with the wind speed detection mechanism 5 to judge the wind speed through the detection results and adjust the air outlet volume according to the wind speed. Example 2:

[0021] Reference Figure 7 - Figure 8 , which is different from the first embodiment in that: a wind speed detection mechanism 5 for detecting strong winds and hurricanes is fixedly provided between the two groups of buffer and damping mechanisms 4.

[0022] The wind speed detection mechanism 5 includes a connecting plate 51, a horizontal box 52, a vertical plate 53, a detection blade 54, a protective frame 55, a trigger plate 56 and a second switch 57. The connecting plate 51 is fixedly connected to the two positioning plates 41, the horizontal box 52 is fixedly connected to the bottom of the connecting plate 51, and the vertical plate 53 is fixedly connected to the top of the connecting plate 51. The detection blade 54 is rotatably connected to one side wall of the vertical plate 53 through a bearing, and the protective frame 55 is rotatably connected to the other side wall of the vertical plate 53 through a bearing and is fixedly connected to the detection blade 54. A plurality of gears are provided inside the horizontal box 52 for rotation through bearings, and a chain transmission is arranged between the plurality of gears. One of the gears is arranged for chain transmission with a gear part between the detection blade 54, and the trigger plate 56 is fixedly connected to the chain between the plurality of gears. There are two second switches 57, which are respectively fixed to both sides of the inner wall of the horizontal box 52.

[0023] In this embodiment: when the wind speed is too high, it will drive the detection blade 54 to rotate. The greater the wind speed, the faster the detection blade 54 rotates. Therefore, under the action of the chain drive, the trigger plate 56 will quickly trigger the second switch 57. The trigger time can be set. For example, if the second switch 57 is triggered within 5 seconds, it means that the wind speed is relatively high at this moment, and the air outlet needs to be adjusted to the first first switch 488. If the second switch 57 is triggered within 10 seconds, it means that the wind speed is relatively high at this moment, and the air outlet needs to be adjusted to the second first switch 488. And so on. All settings can be made. When the detection blade 54 rotates, it will drive the protection frame 55 to rotate. The protection frame 55 rotates to prevent birds and other flying animals from landing. Example 3:

[0024] Reference Figure 9 The difference from the first embodiment is that a stabilizing plate is symmetrically provided on the adjusting plate 3, and a high-voltage line stabilizing mechanism 6 for detecting the swing degree of the high-voltage line and performing reverse pulling is fixed on the stabilizing plate.

[0025] The high-voltage line stabilizing mechanism 6 includes a horizontal plate 61, a stretching plate 62, a support base plate 63, a sleeve plate 64, a rod body 65, a limit plate 66, a second motor 67, a rotating plate 68, a third switch 69 and a reverse stabilizing assembly 610. The horizontal plate 61 is fixedly connected to the bottom of the stabilizing plate, the stretching plate 62 is slidably connected to the inside of the horizontal plate 61 and extends out of the horizontal plate 61, the support base plate 63 is fixedly connected to the top of the stretching plate 62, the bottom of the rod body 65 is rotatably connected to the support base plate 63 through a rotating shaft, and the top is fixedly connected to the sleeve plate 64, and the high-voltage line passes through the sleeve plate 64. There are two limit plates 66, and a gear is rotatably provided on one side wall of the limit plate 66 through a bearing. The two gears are meshed, and one side wall of the gear is fixedly connected to the limit plate 66. The second motor 67 is fixedly connected to one side wall of the limit plate 66 and the output end is fixedly connected to one of the gears. The third switch 69 is fixedly connected to one side wall of the limit plate 66.

[0026] The reverse stabilization assembly 610 includes an extension baffle 6101, a reverse push plate 6102 and a limiting rod 6103. The extension baffle 6101 is fixedly connected to one side wall of the limiting plate 66. The extension baffle 6101 is penetrated by a limiting groove for the reverse push plate 6102 to slide. The limiting rod 6103 is fixedly connected to the side wall of the extension baffle 6101, and there are multiple limiting rods 6103. The four corners of the reverse push plate 6102 are penetrated by slots for the support rod 482 to slide, and a spring is fixed between the reverse push plate 6102 and the limiting rod 6103, and an elastic member for positioning the reverse push plate 6102 is fixedly provided inside the extension baffle 6101.

[0027] In this embodiment: by setting the high-voltage line stabilization mechanism 6, the tension of the high-voltage line is monitored and adjusted in real time. When the wind deflection force acts on the high-voltage line, it drives the high-voltage line to swing to a certain angle. The reverse stabilization component 610 can generate a component force opposite to the wind deflection force, thereby reducing the wind deflection angle of the high-voltage line, so that the high-voltage line remains in a relatively stable state, generates a component force opposite to the wind deflection force, and reduces the wind deflection angle. By starting the second motor 67 to drive the two gears to rotate in opposite directions, the two limit plates 66 are driven to adjust in opposite directions, and the angle is further set. If the safe left and right swing angle of the high-voltage line is 30 degrees, the angle between the two limit plates 66 needs to be set to 60 degrees. After setting, the position of the limit plates 66 is fixed. After fixing, when the high-voltage line swings , driving the sleeve plate 64 and the rod body 65 to swing synchronously. When the swing angle exceeds the set angle, the third switch 69 will be triggered, indicating that a component force opposite to the wind deviation force can be generated at this moment to reduce the wind deviation angle of the high-voltage line. The elastic member for positioning the reverse push plate 6102 is released through the third switch 69, and the spring between the reverse push plate 6102 and the limit rod 6103 is initially in a squeezed state. When the reverse push plate 6102 is positioned, the reverse push plate 6102 will pop out immediately, driving the high-voltage line to push back. If the high-voltage line swings left and right, the two reverse push plates 6102 can limit the high-voltage line to keep the high-voltage line in a relatively stable state. If the high-voltage line only swings in one direction, a reverse push can also limit the high-voltage line to limit the swing distance.

Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
