Description

Technical Field

[0001] The present invention relates to the technical field of lightning arresters, and in particular to a lightning arrester with high protection performance. Background Art

[0002] A lightning arrester is an electrical appliance used to protect electrical equipment from high transient overvoltage hazards and limit the follow-on time and often the follow-on amplitude. A lightning arrester is usually connected between the grid conductor and the ground wire, but sometimes it is also connected next to the electrical winding or between the conductors. A lightning arrester is sometimes also called an overvoltage protector or overvoltage limiter. There are many types of lightning arresters, including metal oxide lightning arresters, line-type metal oxide lightning arresters, gapless line-type metal oxide lightning arresters, fully insulated composite jacketed metal oxide lightning arresters, and detachable lightning arresters. The main types of lightning arresters include tube-type lightning arresters, valve-type lightning arresters, and zinc oxide lightning arresters. The main working principles of each type of lightning arrester are different, but their working essence is the same, all of which are to protect communication cables and communication equipment from damage.

[0003] In the existing technology, lightning arresters are exposed to high-altitude strong winds, high humidity and corrosive environments for a long time. Their surfaces are susceptible to continuous accumulation of pollutants from multiple sources such as bird activities (excrement pollution), atmospheric dust deposition, and industrial salt spray adhesion, resulting in the formation of a conductive pollution layer on the surface of the insulator. This pollution layer will significantly reduce the insulation strength of the equipment, causing an abnormal increase in leakage current, distortion of the electric field distribution, and even inducing surface flashover accidents. At the same time, it will accelerate the corrosion process of metal parts, ultimately leading to the attenuation of the lightning protection function of the lightning arrester and a decrease in system reliability. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a lightning arrester with high protection performance to solve the problems raised in the above background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A lightning arrester with high protection performance, including a lightning arrester body, a rotating shell is provided on the outside of the lightning arrester body, an insulating sleeve is fixedly connected to the outside of the wiring terminal of the lightning arrester body, a rotating platform is provided on the bottom surface of the lightning arrester body, and two rain shields are fixedly installed on the inner circular wall surface of the rotating shell; a protection component is provided inside the rotating shell to ensure the protection effect of the lightning arrester body, and the protection component includes: two connecting frames, both of which are provided inside the rotating shell, flexible brushes are provided on the outside of the connecting frame, a stabilizing column is fixedly installed on the top surface of the connecting frame, and a connecting column is fixedly installed on the bottom surface of the connecting frame. A stabilizing ring is provided on one side of the stabilizing column, and the stabilizing ring is fixedly connected to the top of the arrester body. A movable ring is fixedly installed on one side of the connecting column, and the movable ring and the stabilizing ring are movably connected to the bottom and top of the arrester body respectively. A plurality of fan blades are fixedly installed on the outer circular wall of the rotating table, and a first bearing is fixedly connected to the outside of the arrester body, and the outer circular wall of the outer circle of the first bearing is fixedly connected to the movable ring; the top surface of the rotating shell is provided with a storage component for rotating the connecting frame and the flexible brush; the outer circular wall of the rotating table is provided with a stop component for cleaning and pausing the arrester body.

[0006] By adopting the above technical solution, through the provision of a flexible brush, when the arrester body is working for a long time in a relatively harsh environment, since the arrester body is installed at a high altitude, when wind blows at a high altitude, the wind will blow the fan blades, and the fan blades will drive the rotating table to rotate after being affected by the wind, and then the rotating table will drive the connecting column, the rotating shell, the stabilizing column and the connecting frame to rotate. Since the flexible brush contacts the surface of the arrester body, when the connecting frame rotates, it will drive the flexible brush to perform a circular motion on the surface of the arrester body, thereby facilitating the removal of pollutants such as dust, salt and bird droppings on the surface of the arrester body, avoiding the degradation of insulation performance or surface flashover, and ensuring the lightning protection function of the arrester, so as to reduce the accumulation of a large amount of dust, oil or salt mist and other dirty substances on the surface of the arrester body during long-term high-altitude operation, and then the rotation of the fan blades can disturb the air around the arrester body and increase the air flow rate.

[0007] The top surface of the rotary shaft is provided with a plurality of movable holes, and the top surface and the bottom surface of the rotary shaft are respectively provided with two movable holes, and the connecting frame is movably sleeved with the movable holes, and the top surface of the connecting frame is provided with a downward pressure groove, and the inner bottom surface of the lower pressure groove is fixedly installed with a rotating column, and the outer circular wall of the rotating column is provided with a spiral groove, and the inner bottom surface of the lower pressure groove is provided with a spring, and the spring is movably sleeved with the rotating column. The bottom surface of the mounting block is fixedly installed with an extrusion sleeve, and the inner circular wall of the extrusion sleeve is fixedly installed with a resistance column, and the extrusion sleeve is movably sleeved with the lower pressure groove, and the rotating column is movably sleeved with the inner surface of the extrusion sleeve, and the resistance column is slidably connected with the spiral groove. The bottom surface of the mounting block is provided with a gravity cylinder, and a sponge column is fixedly installed inside the gravity cylinder, and the top surface of the mounting block is provided with a water inlet hole, and the top surface of the gravity cylinder is provided with a connecting hole.

[0008] By adopting the above technical solution, the gravity cylinder is set, and the initial state of the connecting frame and the flexible brush is in contact with the surface of the lightning arrester body. When it rains, rainwater will enter the interior of the gravity cylinder through the water inlet hole and the rotating shell. After the rainwater is collected in the interior of the gravity cylinder, the sponge column will absorb the rainwater. When the sponge column is full of water, the remaining rainwater will accumulate in the interior of the gravity cylinder. Then the sponge column becomes heavier and heavier as it absorbs rainwater, which will affect the gravity of the gravity cylinder itself, and then the gravity cylinder will fall due to gravity, and then the gravity cylinder will drive the water inlet hole, the extrusion sleeve and the resistance column to move downward, and then the extrusion sleeve moves to the inner bottom surface of the downward groove and compresses the spring. At this time, the resistance column will move along the inside of the spiral groove. After the inner wall of the spiral groove is pressed by the resistance column, the rotating column will rotate, and then the rotating column will drive the connecting frame and the flexible brush to rotate toward the inside of the rotating shell. Then, the two connecting frames will rotate into the interior of the rotating shell in a direction close to each other, so as to facilitate the storage of the connecting frame and the flexible brush to prevent rainwater from wetting the flexible brush.

[0009] Preferably, the intermittent assembly includes: a plurality of support rods, a plurality of the support rods are fixedly mounted on the outer circular wall surface of the rotating table, a support ring is provided on the top surface of the rotating table, a rotating ring is fixedly mounted on the top surface of the support ring, the support rods are fixedly mounted on the support ring, a plurality of teeth are fixedly mounted on the top surface of the rotating ring, the outer circular wall surface of the insulating sleeve is fixedly sleeved with a mounting sleeve, the outer circular wall surface of the mounting sleeve is fixedly sleeved with a second bearing, the outer circular wall surface of the outer ring of the second bearing is fixedly sleeved with the inner part of the rotating table, a gear ring is fixedly mounted on the bottom surface of the movable ring, a fixed ring is provided between the movable ring and the support ring, the fixed ring is movably sleeved with the arrester body, a plurality of movable columns are fixedly mounted on the outer circular wall surface of the fixed ring, the outer circular wall surface of the movable column is movably sleeved with gears, and the gears are respectively meshed with the gear ring and the teeth.

[0010] By adopting the above technical solution, through the rotating ring, when the fan blades are rotated by wind, the fan blades will drive the rotating table, support rod and support ring to rotate, and the rotation of the support ring will drive the rotating ring to rotate, and then the teeth will engage the gears following the rotating ring during rotation, causing the gears to rotate, and the gears will engage and drive the gear ring to rotate during rotation. Then the gear ring drives the movable ring and the connecting column to rotate, so that the rotating shell and the connecting frame can be made to perform circular motion along the outside of the lightning arrester body. Since multiple teeth are spaced apart on the rotating ring, each time the teeth engage and drive the gears to rotate one circle, the gears will disengage from the teeth, so that the gears and the gear ring can stop rotating. Subsequently, under the rotation of the rotating ring, the teeth will engage with the gears again, so that the intermittent rotation of the connecting frame and the flexible brush can be achieved, avoiding long-term contact and friction between the flexible brush and the outer wall of the lightning arrester body, resulting in accelerated wear of the surface materials of both, such as metal, coating and insulation layer, affecting its lightning protection performance. At the same time, wind-driven rotation cleaning can replace manual climbing cleaning, thereby reducing the safety risks of high-altitude operations.

[0011] Preferably, a rotation groove is provided on the outer circular wall surface of the stabilizing ring, and a limiting groove is provided on the inner top surface and the inner bottom surface of the rotation groove respectively.

The sliding plate is movably connected to the rotation groove, and the sliding block is movably connected to the limiting groove.

[0012] By adopting the above technical solution, through the stabilizing column, when the gear ring and the movable ring drive the connecting column to rotate the rotating shell, the rotating shell will drive the stabilizing column to rotate, and then the stabilizing column will drive the sliding plate and the sliding block to perform circular motion inside the rotating groove and the limiting groove respectively, thereby facilitating the rotation limitation of the stabilizing column and supporting the top of the rotating shell to enable it to rotate stably.

[0013] Preferably, a blocking net is fixedly sleeved on the inner circular wall surface of the water inlet hole, and a plurality of exhaust holes are opened on the bottom surface of the gravity cylinder.

[0014] By adopting the above technical solution, through the setting of the blocking net, when rainwater enters the interior of the gravity cylinder through the water inlet hole and the connecting hole, the blocking net can block the flexible garbage floating in the air due to the wind, such as plastic bags, leaves, etc.; when it is sunny after the rain, since the gravity cylinder is exposed to the sky without any shelter, the sun will directly shine on the gravity cylinder, and then the water inside the gravity cylinder and the sponge column will slowly evaporate, and then the weight of the gravity cylinder will become lighter, and then the gravity cylinder will lose the gravity of the compression spring, and then the spring will push the extrusion sleeve to drive the resistance column to move upward, and the movement of the resistance column along the spiral groove will cause the rotating column to rotate and drive the connecting frame and the flexible brush to rotate and reset, so that the flexible brush can re-contact the surface of the lightning arrester body for cleaning.

[0015] Preferably, a limiting rod is fixedly mounted on the bottom surface of the mounting block, two guide frames are fixedly mounted on the outer circumferential wall surface of the rotating shell, and the limiting rod is slidably connected to the guide frames.

[0017] Preferably, a connecting ring is fixedly mounted on the bottom surface of the mounting block, the outer circumferential wall surface of the connecting ring is provided with threads, the inner circumferential wall surface of the connecting hole is provided with threads, and the connecting ring is threadedly connected to the connecting hole.

[0018] By adopting the above technical solution, through the gravity cylinder that is set, the staff can rotate the gravity cylinder to loosen it, and then move the gravity cylinder from the outside of the connecting ring, so as to facilitate the disassembly of the gravity cylinder. Conversely, the gravity cylinder can be installed, so as to facilitate the replacement of the gravity cylinder by the staff, and prevent the gravity cylinder and the sponge column from being powdered during long-term use at high altitude, thereby preventing the sponge column from reducing the water absorption effect of the sponge column.

[0019] Preferably, the top and bottom surfaces of the connecting frame are respectively provided with threaded columns, a cleaning frame is provided on the outside of the connecting frame, the cleaning frame is fixedly installed with the flexible brush, and the threaded columns pass through the cleaning frame and are threadedly connected to the connecting frame.

[0020] By adopting the above technical solution, the cleaning frame and the flexible brush can be disassembled so that the staff can clean or replace the flexible brush.

[0021] Preferably, a detection groove is opened on the inner circular wall surface of the rotating shell, a miniature infrared temperature sensor is fixedly installed on the inner circular wall surface of the detection groove, and a transparent block is fixedly sleeved on the inner circular wall surface of the detection groove.

[0022] By adopting the above technical solution, a micro infrared temperature sensor is set up, which can generate infrared light to detect the temperature of the lightning arrester body, making it convenient to detect the temperature outside the lightning arrester body, so as to promptly detect aging or moisture problems of the lightning arrester body.

[0023] Preferably, a mounting shell is fixedly mounted on the outer circumferential wall of the rotating shell, a fixing groove is opened on one side of the mounting shell, a plurality of indicator lights are fixedly mounted on one side of the inner side of the fixing groove, and a transparent plate is fixedly mounted inside the fixing groove.

[0025] In summary, the present invention mainly has the following beneficial effects: 1. The present invention uses a flexible brush to fit the curved surface of the arrester body with a preset contact pressure, forming a closed-loop spiral trajectory driven by a connecting frame. It also uses a high-altitude continuous wind field to achieve automatic operation without a power source, so as to remove pollutants such as dust, salt crystals, and bird droppings attached to the arrester body, reduce the corrosion caused by pollutants on the arrester body, and thus prevent the arrester body from attenuating its lightning protection function. 2. The present invention generates an airflow field through the rotation of the fan blades, thereby reducing the probability of particle adsorption; 3. The present invention collects rainfall through a water inlet, a gravity cylinder, and a sponge column, utilizing the capillary adsorption properties of the sponge material to achieve gradient accumulation of water. Furthermore, the spiral progressive collection action of the flexible brush is achieved through the angular displacement drive of the rotating column. 4. The present invention uses high-altitude wind-driven fan blades, a rotating platform, support rods, a support ring, a rotating ring, teeth, gears, a gear ring, a movable ring, a connecting column, a rotating shell, a connecting frame, and a flexible brush to cooperate with each other to form a multi-stage power transmission.

The present invention is designed to fit the curved surface through the flexible brush 5, so as to be easily adapted to the shape of arresters of different specifications; 6. The present invention forms an "engagement, indexing and disengagement" cycle by periodically engaging and disengaging multiple spaced teeth on a rotating ring with the gear. The gear disengages from the teeth after each rotation, and the connecting frame is driven by the gear ring to complete a single cleaning action. The cleaning action is paused after a single cleaning to avoid surface damage to the arrester body caused by long-term continuous friction. BRIEF DESCRIPTION OF THE DRAWINGS

After being affected by the wind, the fan blades 25 will drive the rotating platform 3 to rotate, and then the rotating platform 3 will drive the connecting column 8, the rotating shell 2, the stabilizing column 7 and the connecting frame 4 to rotate. Since the flexible brush 5 contacts the surface of the arrester body 1, when the connecting frame 4 rotates, it will drive the flexible brush 5 to perform a circular motion on the surface of the arrester body 1, thereby facilitating the removal of pollutants such as dust, salt and bird droppings on the surface of the arrester body 1, avoiding the degradation of insulation performance or surface flashover, and ensuring the lightning protection function of the arrester, so as to reduce the accumulation of a large amount of dust, oil or salt mist and other dirty substances on the surface of the arrester body 1 during long-term high-altitude operation, and then the rotation of the fan blades 25 can disturb the air around the arrester body 1 and increase the air flow rate.

When it rains, rainwater will enter the interior of the gravity cylinder 20 through the water inlet hole 21 and the rotating shell 2. After the rainwater is collected in the interior of the gravity cylinder 20, the sponge column 23 will absorb the rainwater. When the sponge column 23 is full of water, the remaining rainwater will accumulate in the interior of the gravity cylinder 20. Then, the sponge column 23 becomes heavier as it is full of rainwater, which will affect the gravity of the gravity cylinder 20 itself, and then the gravity cylinder 20 will fall due to gravity, and then the gravity cylinder 20 will bring The water inlet hole 21, the extrusion sleeve 18 and the resistance column 19 move downward, and then the extrusion sleeve 18 moves toward the inner bottom surface of the downward pressure groove 14 and compresses the spring 17.

Since the multiple teeth 32 are spaced apart on the rotating ring 31, each time the teeth 32 mesh and drive the gear 35 to rotate one circle, the gear 35 will disengage from the teeth 32, thereby making the gear 35 and the gear ring 34 stop rotating. Subsequently, on the rotating ring 3 1, the teeth 32 will mesh with the gear 35, thereby realizing intermittent rotation of the connecting frame 4 and the flexible brush 5, avoiding long-term contact and friction between the flexible brush 5 and the outer wall of the lightning arrester body 1, which will cause accelerated wear of the surface materials of both such as metal, coating and insulation layer, affecting its lightning protection performance. At the same time, wind-driven rotation cleaning can replace manual climbing cleaning, thereby reducing the safety risks of high-altitude operations. When the gear ring 34 and the movable ring 11 drive the connecting column 8 to rotate the rotating shell 2, the rotating shell 2 will drive the stabilizing column 7 to rotate, and then the stabilizing column 7 will drive the sliding plate 39 and the sliding block 40 to perform circular motion inside the rotating groove 37 and the limiting groove 38 respectively, thereby facilitating the rotation limit of the stabilizing column 7, and at the same time supporting the top of the rotating shell 2 to make it rotate stably.

Conversely, the gravity cylinder 20 can be installed, so as to facilitate the staff to replace the gravity cylinder 20, and prevent the gravity cylinder 20 and the sponge column 23 from being powdered during long-term use at high altitude, resulting in a reduction in the water absorption effect of the sponge column 23.

[0033] refer to Figure 1 、 Figure 13 、 Figure 14 and Figure 15The inner wall of the rotating shell 2 is provided with a detection groove 49, and a miniature infrared temperature sensor 50 is fixedly installed on the inner wall of the detection groove 49. A transparent block 51 is fixedly sleeved on the inner wall of the detection groove 49. A mounting shell 52 is fixedly installed on the outer wall of the rotating shell 2. A fixing groove 53 is provided on one side of the mounting shell 52. Several indicator lights 47 are fixedly installed on one side of the fixing groove 53. A transparent plate 48 is fixedly installed inside the fixing groove 53. By setting up a miniature infrared temperature sensor 50, the miniature infrared temperature sensor 50 can generate infrared light to detect the temperature of the lightning arrester body 1, which is convenient for detecting the temperature outside the lightning arrester body 1, so as to timely discover the aging or moisture problems of the lightning arrester body 1. When the lightning arrester body 1 and the rotating shell 2 are installed at high altitude, the light generated by the indicator light 47 can help the staff quickly find the installation position of the lightning arrester body 1 at high altitude when maintaining the lightning arrester body 1.

[0034] Working principle: Please refer to Figures 1-12 As shown, by the provision of the flexible brush 5, when the arrester body 1 is working for a long time in a relatively harsh environment, since the arrester body 1 is installed at a high altitude, when wind blows at a high altitude, the wind will blow the fan blades 25, and the fan blades 25 will drive the rotating table 3 to rotate after being affected by the wind, and then the rotating table 3 will drive the connecting column 8, the rotating shell 2, the stabilizing column 7 and the connecting frame 4 to rotate. Since the flexible brush 5 contacts the surface of the arrester body 1, when the connecting frame 4 rotates, it will drive the flexible brush 5 to perform a circular motion on the surface of the arrester body 1, thereby facilitating the removal of pollutants such as dust, salt and bird droppings on the surface of the arrester body 1, avoiding the degradation of insulation performance or surface flashover, and ensuring the lightning protection function of the arrester, so as to reduce the accumulation of a large amount of dust, oil or salt mist and other dirty substances on the surface of the arrester body 1 during long-term high-altitude operation, and then the rotation of the fan blades 25 can disturb the air around the arrester body 1 and increase the air flow rate.

[0035] refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7, through the provided gravity cylinder 20, the initial state of the connecting frame 4 and the flexible brush 5 is in contact with the surface of the arrester body 1. When it rains, rainwater will enter the interior of the gravity cylinder 20 through the water inlet hole 21 and the rotating shell 2. After the rainwater is collected in the interior of the gravity cylinder 20, the sponge column 23 will absorb the rainwater. When the sponge column 23 is full of water, the remaining rainwater will accumulate in the interior of the gravity cylinder 20. Then, the sponge column 23 becomes heavier as it is full of rainwater, which will affect the gravity of the gravity cylinder 20 itself, and then the gravity cylinder 20 will fall due to gravity, and then the gravity cylinder 20 will bring The water inlet hole 21, the extrusion sleeve 18 and the resistance column 19 move downward, and then the extrusion sleeve 18 moves toward the inner bottom surface of the downward pressure groove 14 and compresses the spring 17. At this time, the resistance column 19 moves along the inner side of the spiral groove 16. After the inner wall of the spiral groove 16 is pressed by the resistance column 19, the rotating column 15 rotates, and then the rotating column 15 drives the connecting frame 4 and the flexible brush 5 to rotate toward the inside of the rotating shell 2. Subsequently, the two connecting frames 4 rotate toward each other into the interior of the rotating shell 2, thereby facilitating the storage of the connecting frame 4 and the flexible brush 5 to prevent rainwater from wetting the flexible brush 5. When it is sunny after rain, since the gravity cylinder 20 is exposed to the sky without any shelter, the sun will directly shine on the gravity cylinder 20, and then the moisture inside the gravity cylinder 20 and the sponge column 23 will slowly evaporate, and then the weight of the gravity cylinder 20 will become lighter, and then the gravity cylinder 20 will lose the gravity of the compression spring 17, and then the spring 17 will push the extrusion sleeve 18 to drive the resistance column 19 to move upward, and the movement of the resistance column 19 along the spiral groove 16 will cause the rotating column 15 to rotate and drive the connecting frame 4 and the flexible brush 5 to rotate and reset, so that the flexible brush 5 can re-contact the surface of the lightning arrester body 1 for cleaning.

[0036] refer to Figure 1 、 Figure 2 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12, through the provided rotating ring 31, when the fan blades 25 are rotated by the wind, the fan blades 25 will drive the rotating platform 3, the support rod 26 and the support ring 30 to rotate, and the rotation of the support ring 30 will drive the rotating ring 31 to rotate, and then the teeth 32 will mesh with the gear 35 during the rotation of the rotating ring 31, so that the gear 35 rotates, and the gear 35 will mesh with the gear ring 34 during the rotation, and then the gear ring 34 will rotate by driving the movable ring 11 and the connecting column 8, thereby making the rotating shell 2 and the connecting frame 4 perform a circular motion along the outside of the arrester body 1. Since the multiple teeth 32 are spaced apart on the rotating ring 31 Whenever the teeth 32 are engaged and drive the gear 35 to rotate one circle, the gear 35 will disengage from the teeth 32, thereby stopping the rotation of the gear 35 and the gear ring 34. Subsequently, under the rotation of the rotating ring 31, the teeth 32 will engage with the gear 35 again, thereby realizing the intermittent rotation of the connecting frame 4 and the flexible brush 5, avoiding long-term contact and friction between the flexible brush 5 and the outer wall of the lightning arrester body 1, resulting in accelerated wear of the surface materials of the two, such as metal, coating and insulation layer, affecting its lightning protection performance. At the same time, wind-driven rotation cleaning can replace manual climbing cleaning, thereby reducing the safety risks of high-altitude operations.
