DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] Example: Figure 1-5 As shown, a wind-resistant and disaster-resistant reinforcement structure for power lines of the present invention comprises a power frame 1, and a pair of insulating roller clamps 2 are arranged on the power frame 1, each of the insulating roller clamps 2 is composed of an upper insulating roller 3 and a lower insulating roller 3, and the surfaces of the upper insulating roller 2 and the lower insulating roller 3 are provided with wheel grooves 4, and the wheel grooves 4 between the upper insulating roller 2 and the lower insulating roller 3 form a clamping opening for clamping the power line, and the power frame 1 is provided with an insulating fixing frame 5 for fixing the power line;

[0028] A tensioning mechanism 6 for adjusting the tension of the power line is provided between the insulating fixing frame 5 and the insulating roller clamp 4.

The output end of the tension detection mechanism 7 and the wind force detection mechanism 7 are both connected to the controller. The tensioning mechanism 6 is connected to the controller 8. When the wind force detection mechanism 9 detects that the wind force reaches the set adjustment value, the controller 8 controls the tensioning mechanism 6 to work, so as to adjust the tension of the power line to the set value under the corresponding wind force; and when the wind force detection mechanism 7 detects that there is no wind or weak wind, the controller 7 controls the tensioning mechanism 6 to work, so as to reduce the tension value of the power line. A wind force detection mechanism 9 is arranged on the power rack. When the wind force detection mechanism 9 detects that the wind force reaches the set adjustment value, the controller 8 controls the tensioning mechanism 6 to adjust the tension of the power line to the set value under the corresponding wind force; and when the wind force detection mechanism 7 detects that there is no wind or weak wind, the controller 7 controls the tensioning mechanism 6 to reduce the tension value of the power line. In this way, in the case of strong wind, the tension of the power line can be adjusted, so as to avoid the power line in strong wind weather. Due to the small tension, the power line is easy to swing with a large amplitude and is easy to be damaged. When the wind force detection mechanism 7 detects that there is no wind or weak wind, the controller 7 controls the tensioning mechanism 6 to reduce the tension value of the power line. In this way, it is avoided that the tension is too large in daily life and the load of the power rack is increased.

The power line is fixedly tensioned by setting a specific tensioning mechanism 6, wherein the take-up motor drives the take-up drum 26 to rotate, and the rotating take-up drum reels the reel wire rope, thereby driving the sliding seat 11 to move along the slide rail 10, and adjusting the tension of the power line, wherein the detection grating 19 is used to detect the bottom position of the telescopic rod 16, and to detect the length of the telescopic rod 15 extending out of the limit tube 15, thereby realizing the detection of the falling degree of the power line, thereby detecting the tension of the power line.

[0030] A spring shock absorber 14 is provided between the sliding seat and the winding wire rope, so as to play a role of buffering and shock absorption.

[0031] The tension detection mechanism 7 includes a vertically upward limiting cylinder 15 arranged on the power rack 1, and a telescopic rod 16 that can be telescoped along the limiting cylinder 15 is arranged in the limiting cylinder 15, and a detection plate 17 is hinged on the top of the telescopic rod 16, and the detection plate 17 is provided with an insulating U-shaped nut 18, and a cavity for the power line to pass through is formed between the insulating U-shaped nut 18 and the detection plate 17, and a detection grating 19 arranged along the limiting cylinder 15 is arranged in the limiting cylinder 15, and the detection grating 19 is arranged along the limiting cylinder 15, and the detection grating 19 is used to detect the bottom position of the telescopic rod 16, and to detect the length of the telescopic rod 15 extending out of the limiting cylinder 15, thereby realizing the detection of the falling degree of the power line, thereby detecting the tension of the power line, and the detection grating 19 is connected to the controller 8, and the positioning module 23 is used to locate the geographical location of the power rack, and the communication module 24 is used to upload the tension degree value of the power line detected by the tension detection mechanism 7 to the database, and the staff can view the data in the database through the mobile device.

[0032] Wherein, the limiting cylinder 15 and the telescopic rod 16 are both made of insulating material, thus playing an insulating role.

[0033] The surfaces of the upper insulating roller 3, the lower insulating roller 3, the first insulating wheel 12 and the second insulating wheel 13 are all provided with an anti-wear rubber layer 20, which plays an anti-wear role.

[0034] The insulating fixing frame 5 comprises an insulating frame 21 fixed on the power frame, and the insulating frame 21 is provided with curved guide frames 22 curved inward at both ends, which plays a role in preventing wear.

[0035] The controller 8 is also provided with a positioning module 23 and a communication module 24. The positioning module 23 is used to locate the geographical location of the power rack, and the communication module 24 is used to upload the tension degree value of the power line detected by the tension detection mechanism 7 to the database. The staff can view the data in the database through a mobile device.

[0036] The controller 8 is further provided with an alarm module 25 , and the alarm module 25 is used to issue an alarm message when the tension of the power line detected by the tension detection mechanism 7 is abnormal.

[0037] Working principle: A wind force detection mechanism 9 is arranged on the power rack. When the wind force detection mechanism 9 detects that the wind force reaches the set adjustment value, the controller 8 controls the tensioning mechanism 6 to adjust the tension of the power line to the set value under the corresponding wind force; and when the wind force detection mechanism 7 detects that there is no wind or weak wind, the controller 7 controls the tensioning mechanism 6 to reduce the tension value of the power line. In this way, the tension of the power line can be adjusted in the case of strong wind, so as to avoid the power line in strong wind weather. Due to the small tension, the power line is easy to swing with a large amplitude and is easy to be damaged. When the wind force detection mechanism 7 detects that there is no wind or weak wind, the controller 7 controls the tensioning mechanism 6 to reduce the tension value of the power line. In this way, excessive tension is avoided in daily life, which increases the load of the power rack.
