[0002] The maintenance of power towers is one of the important guarantees for the operation and development of modern power systems.

[0003] Disasters. Since the direct harm of lightning strikes cannot be avoided, the main way to reduce the damage of lightning is to install lightning protection devices.

It is extremely easy to cause sudden breakage and falling to injure people, posing a safety hazard, so it needs to be protected.
[0004] At the same time, since the protective equipment generally has a large contact area with the wind, it is subject to a greater force from the wind, and the protective device is prone to the risk of deformation and falling.

[0014] The beneficial effects of the present invention are as follows:
[0015] 1. The windproof structure of a lightning protection device described in the present invention is provided with a blocking plate. Since the blocking plate is slidably connected to the blocking chute, when wind blows onto the blocking plate, if the wind force is strong, it will slide on the blocking chute due to the action of the force, which can alleviate the force of the wind and prevent it from blowing directly onto the protection unit. Moreover, since the blocking plate and the protection unit both serve as protection for the lightning rod, the height of the blocking plate is relatively high. If the blocking plate is fixed on the support seat, when the blocking plate is affected by wind force, due to the fixed bottom, the fixed position will be subject to the tension brought by the blocking plate, which is prone to deformation or breakage, and cannot play the role of blocking wind force. The present invention improves the blocking plate into a sliding structure, thereby avoiding damage caused by fixation.
[0016] 2. The windproof structure of a lightning protection device described in the present invention is equipped with a safety mechanism. When the wind is too strong, the blocking plate moves and contacts the safety mechanism. Therefore, the blocking plate will exert a force on the safety mechanism. Due to the action of wind, the protection unit can rotate around the rotating axis. The action of the blocking plate on the safety mechanism can reduce the rotation speed of the protection unit 3, thereby preventing it from falling off and flying out due to excessive centrifugal force caused by excessive rotation speed.

DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] like Figures 1 to 4 As shown, the windproof structure of a lightning protection device of the present invention comprises a base 1, and the base 1 is fixedly mounted on the top of the power tower;
[0025] A support base 2 is fixedly mounted on the upper end of the base 1. A through hole for the lightning rod to pass through is opened in the middle of the base 1. A protection unit 3 is rotatably mounted in the middle of the support base 2. A barrier unit 4 is provided on the outer side of the protection unit 3. The barrier unit 4 is slidably connected to the support base 2.
[0026] The blocking unit 4 includes a blocking mechanism 5; there are four blocking mechanisms 5, which are evenly arranged around the outside of the protection unit 3; the support base 2 is provided with a blocking slot 6; the blocking mechanism 5 is slidably connected to the blocking slot 6; the blocking mechanism 5 includes a blocking plate 51, a corrugated rubber sleeve 52 and a first spring 53; the blocking plate 51 is slidably connected to the blocking slot 6; the corrugated rubber sleeve 52 includes a first rubber sleeve 521 and a second rubber sleeve 522; the corrugated rubber sleeve 52 is hollow; the first rubber sleeve 521 is fixedly connected to the blocking groove 6 on the side of the blocking plate 51 away from the protection unit 3, and the first rubber sleeve 521 is fixedly connected to the blocking plate 51; the second rubber sleeve 522 is fixedly connected to the blocking groove 6 on the side of the blocking plate 51 close to the protection unit 3, and the second rubber sleeve 522 is fixedly connected to the blocking plate 51; one end of the spring is fixedly connected to the side of the blocking plate 51 away from the protection unit 3, and the other end of the first spring 53 is fixed on the side wall of the blocking groove 6, and the first rubber sleeve 521 is sleeved on the first spring 53.
[0027] When in use, the lightning rod is installed on the top of the power tower through the through hole on the base 1, and the windproof mechanism protects the lightning rod. The lightning rod is surrounded by the protection unit 3 to effectively block the wind and the lightning rod. When the wind generally blows in one direction, the wind force is constantly changing, but the flow direction remains unchanged. The blocking mechanism 5 is set around the protection unit 3. When the wind blows from one direction, the blocking plate 51 is slidably connected to the blocking chute 6. When the wind blows on the blocking plate 51, if the wind force is large, due to the action of the force The barrier plate 51 slides on the blocking chute 6, which can alleviate the force of the wind and prevent it from blowing directly to the protection unit 3. Moreover, since the blocking plate 51 and the protection unit 3 are both protection for the lightning rod, the blocking plate 51 is relatively high. If the blocking plate 51 is fixed on the support seat 2, when the blocking plate 51 is affected by the wind, the fixed position will be subject to the tension brought by the blocking plate 51 due to the fixed bottom, which is easy to deform or break, and cannot play the role of blocking the wind. The present invention improves the blocking plate 51 into a sliding structure , thereby avoiding damage caused by fixation, and the present invention provides the first rubber sleeve 521, the second rubber sleeve 522 and the first spring 53, which can effectively avoid the problem of deformation and breakage caused by the blocking plate 51 moving to the final end and being unable to move due to excessive wind force. Due to the use of the first rubber sleeve 521 and the second rubber sleeve 522, an effective buffer is generated, so that the blocking plate 51 is in a flexible unloading state no matter how the force is applied. Moreover, due to the use of the first spring 53, on the one hand, it can ensure that the position of the blocking plate 51 is restored after the wind stops, and on the other hand, a pulling force is generated during the action of the wind, which can cause the blocking plate 51 to have a certain back and forth swinging tendency, thereby fully reducing the force of the wind and reducing the impact of the wind on the protection unit 3. At the same time, when the wind flows in one direction, the back and forth bounce of the blocking plate 51 will undoubtedly disrupt the flow of wind. At this time, the wind on the protection unit 3 is not a direct force, but a relatively dispersed force, which can fully ensure that the force on the protection unit 3 is reduced and ensure that it is not damaged by strong winds.
[0028] As an embodiment of the present invention, a rolling chute 61 is provided at the bottom of the blocking chute 6 ; a rolling shaft 62 is rotatably connected to the lower portion of the blocking plate 51 , and the rolling shaft 62 is slidably connected to the rolling chute 61 .
[0029] During use, the baffle plate 51 slides when subjected to the force of wind, but friction is generated due to the movement between the planes, and since the lower part of the baffle plate 51 is subjected to force, the baffle plate 51 may get stuck during movement due to uneven force, and thus cannot unload the force and disrupt the airflow. Adding a rolling shaft 62 can change the rolling friction of the baffle plate 51, reduce resistance, and be more conducive to unloading the force of the wind and disrupting the airflow. At the same time, since the rolling shaft 62 independently supports the baffle plate 51, when the baffle plate 51 is subjected to force, it swings while moving, further promoting the effect of disrupting the airflow, and ensuring that the force on the baffle plate 51 is reduced, to ensure that there will be no deformation problems caused by excessive wind force.
[0030] As an embodiment of the present invention, the protection unit 3 includes a protection mechanism 31, a support mechanism 32 and a safety mechanism 33; the support mechanism 32 includes a rotating shaft 321 and a support shaft 322, the rotating shaft 321 is a hollow cylindrical pipe, the rotating shaft 321 is located in the middle of the support seat 2 and is rotatably connected to the support seat 2, and a connecting through hole is provided in the middle of the support seat 2 to connect the rotating shaft 321 and the through hole on the base 1; there are four support shafts 322, one end of the support shaft 322 is fixedly connected to the rotating shaft 321, and the other ends of the four support shafts 322 are fixedly connected to the four protection mechanisms 31 one by one; one end of several of the safety mechanisms 33 is fixedly installed on the side of the protection mechanism 31 away from the rotating shaft 321, and the other end of the safety mechanism 33 is in contact with the blocking plate 51.
[0031] During use, when the wind force acts on the blocking plate 51, the blocking plate 51 moves and contacts the safety mechanism 33, so the blocking plate 51 will exert force on the safety mechanism 33. Due to the action of wind, the protection unit 3 can rotate around the rotating shaft 321. The action of the blocking plate 51 on the safety mechanism 33 can reduce the rotation speed of the protection unit 3, thereby preventing it from falling off and flying out due to excessive centrifugal force caused by excessive rotation speed.
[0032] As an embodiment of the present invention, the protection mechanism 31 includes a protection plate 311, which is a quarter-circular circular plate. The four protection plates 311 in the protection mechanism 31 can be combined into a complete circle; the height of the protection plate 311 is higher than the blocking plate 51; the upper part of the protection plate 311 is higher than the blocking plate 51 and is provided with several blades on the side close to and away from the rotating shaft 321.
[0033] During use, when the wind blows, due to the presence of several blades above the protective plate 311, the protective plate 311 will rotate around the rotating shaft 321 due to the force exerted on it, thereby decomposing the force exerted on the protective plate 311 by the wind, thereby ensuring that the protective plate 311 will not be blown over by the wind. Moreover, due to the continuous rotation of the protective plate 311, a protective airflow will be formed around the lightning rod, thereby further protecting the lightning rod.
[0034] As one embodiment of the present invention, the safety mechanism 33 includes a mounting seat 331, a second spring 332, a telescopic shaft 333, a mounting shaft 334, and a roller 335. The mounting seat 331 is fixedly mounted on the protective plate 311. The mounting seat 331 is hollow, and the telescopic shaft 333 is slidably mounted inside the mounting seat 331. The second spring 332 is located inside the mounting seat 331. One end of the second spring 332 is fixedly mounted on the protective plate 311, and the other end is fixedly mounted on the telescopic shaft 333. The telescopic shaft 333 is rotatably connected to one end of two mounting shafts 334 on the side away from the protective plate 311. The other ends of the mounting shafts 334 are rotatably connected to the rollers 335, and the two mounting shafts 334 are connected by a tension spring. The rollers 335 contact the blocking plate 51. The side of the blocking plate 51 that contacts the rollers 335 is provided with a rubber pad.
[0035] When in use, when the wind is strong, the rotation of the protection plate 311 will drive the safety mechanism 33 to rotate. Since the rotation speed is too fast and the stronger the wind is, the more likely it is to cause damage and deformation of the protection unit 3. Therefore, the safety mechanism 33 is set to contact with the blocking plate 51. When the wind is strong, the blocking plate 51 moves to squeeze the safety mechanism 33. At this time, due to the increase in the force between the blocking plate 51 and the safety mechanism 33, the rotation speed of the protection plate 311 will be slowed down to ensure that the protection plate 311 will not be damaged due to excessive rotation while unloading the force. At the same time, the safety mechanism 33 supports the blocking plate 51. The blocking plate 51 will generate a force around the axial direction of the rolling axis 62 when it is subjected to force, and it is easy to deform due to the height of the equipment. With several The support of the safety mechanism 33 can ensure that the blocking plate 51 will not be deformed, and when the blocking plate 51 squeezes the safety mechanism 33, the roller 335 contacts the blocking plate 51. Due to the action of the force, the two mounting shafts 334 rotate to decompose the force of the blocking plate 51. When the force increases, the telescopic shaft 333 begins to move and compress to further decompose the impact of the wind. The setting of the mounting mechanism ensures the rotation stability of the protection mechanism 31. At the same time, the protection mechanism 31 rotates and the safety mechanism 33 rotates synchronously. The blocking plate 51 is supported by the intermittent safety mechanism 33, so that the blocking plate 51 continuously moves back and forth to promote the disruption of the airflow, ensuring that the protection unit 3 is minimally affected by the airflow, thereby increasing the protection effect.
[0036] As an embodiment of the present invention, the support shaft 322 is made of elastic rubber material.
[0037] During use, the rotation of the protective plate 311 generates centrifugal force. If metal materials are used, rigid pulling force will be generated, which will cause the protective plate 311 to fall off. The present invention uses elastic rubber material, which will generate elastic pulling force to offset the centrifugal force generated when the protective plate 311 rotates. At the same time, the safety mechanism 33 is set to generate a force to offset the centrifugal force under the action of the blocking plate 51, thereby ensuring the balance of the protective plate 311.
[0038] During operation, when the wind is strong, the rotation of the protection plate 311 will drive the safety mechanism 33 to rotate. Since the rotation speed is too fast and the stronger the wind is, the more likely it is to cause damage and deformation of the protection unit 3. Therefore, the safety mechanism 33 is set to contact with the blocking plate 51. When the wind is strong, the blocking plate 51 moves to squeeze the safety mechanism 33. At this time, since the force between the blocking plate 51 and the safety mechanism 33 becomes larger, the rotation speed of the protection plate 311 will be slowed down, ensuring that the protection plate 311 will not be damaged due to excessive rotation while unloading the force. At the same time, the safety mechanism 33 supports the blocking plate 51. The blocking plate 51 will generate a force around the axial direction of the rolling axis 62 when it is subjected to force. Since the equipment is high and prone to deformation, with the support of several safety mechanisms 33, it can be ensured that the blocking plate 311 is The partition 51 will not be deformed, and when the blocking plate 51 squeezes the safety mechanism 33, the roller 335 contacts the blocking plate 51. Due to the action of the force, the two mounting shafts 334 rotate to decompose the force of the blocking plate 51. When the force increases, the telescopic shaft 333 begins to move and compress to further decompose the influence of the wind. The setting of the mounting mechanism ensures the rotation stability of the protection mechanism 31. At the same time, the protection mechanism 31 rotates and the safety mechanism 33 rotates synchronously. The blocking plate 51 is supported by the intermittent safety mechanism 33, so that the blocking plate 51 continuously moves back and forth to promote the disruption of the airflow, ensuring that the protection unit 3 is minimally affected by the airflow, thereby increasing the protection effect. In the present invention, a blocking mechanism 5 is set around the protection unit 3. When the wind blows from one direction, the blocking mechanism 5 can be adjusted to the maximum value. When the wind blows toward the shielding plate 51, since the blocking plate 51 is slidably connected to the blocking chute 6, when the wind blows onto the blocking plate 51, if the wind force is large, the blocking plate 51 will slide on the blocking chute 6 due to the action of the force, which can alleviate the force of the wind and will not blow directly toward the protection unit 3. Moreover, since the blocking plate 51 and the protection unit 3 are both protection for the lightning rod, the blocking plate 51 is relatively high. If the blocking plate 51 is fixed on the support seat 2, when the blocking plate 51 is affected by the wind, since the bottom is fixed, the fixed position will be subject to the tension brought by the blocking plate 51, which is easy to deform or break, and cannot play the role of blocking the wind force. The present invention improves the blocking plate 51 into a slidable structure, thereby avoiding the damage caused by fixation, and the present invention provides a first rubber sleeve 521 and a second rubber sleeve 522. The rubber sleeve 522 and the first spring 53 can effectively prevent the blocker 51 from being unable to move to the final end due to excessive wind force, causing deformation and breakage. Due to the use of the first rubber sleeve 521 and the second rubber sleeve 522, an effective buffer can be generated, so that the blocker 51 is in a flexible unloading state no matter how the force is applied. In addition, due to the use of the first spring 53, on the one hand, it can ensure the restoration of the position of the blocker 51 after the wind stops. On the other hand, the pulling force generated during the action of the wind can cause the blocker 51 to have a certain back and forth swinging tendency. At this time, the force of the wind can be fully weakened, reducing the impact of the wind on the protection unit 3. At the same time, when the wind flows in one direction, the back and forth bouncing of the blocker 51 will undoubtedly disrupt the flow of the wind.At this time, the wind acting on the protection unit 3 is not a direct force, but a relatively dispersed force, which can fully ensure that the force on the protection unit 3 is reduced and ensure that it is not damaged by strong winds.
