Description

Technical Field

[0001] This invention belongs to the field of insulator cleaning technology, and in particular relates to an all-directional wind-driven cleaning device for post-type insulators. Background Technology

[0002] Insulators, as key components ensuring electrical insulation and mechanical support in power systems, are widely used in transmission lines, substations, and other facilities. Prolonged exposure to complex outdoor environments makes insulator surfaces highly susceptible to accumulating dust, salt, industrial pollutants, bird droppings, and other impurities, forming a layer of contaminants. In humid climates, this contaminant layer significantly reduces the insulation performance of insulators, leading to increased leakage current and even flashover faults, seriously threatening the safe and stable operation of the power system. According to statistics, approximately 35% of power equipment failures are related to decreased insulation performance, and nearly 60% of these are caused by contaminant accumulation. Therefore, regular and effective cleaning of insulator surfaces is a crucial measure for preventing flashover accidents and ensuring a reliable power supply.

[0003] Currently, there are various cleaning technologies for insulator surfaces, mainly divided into power-off cleaning, power-on wiping, and live cleaning. Among them, live cleaning includes live water cleaning, live electric blowing cleaning, live dry cleaning, and live chemical cleaning.

[0004] Of the cleaning methods mentioned above, cleaning during power outages typically involves using cloths or simple tools to clean the equipment, but this can result in incomplete cleaning. Furthermore, some equipment experiences infrequent power outages, leading to delays in cleaning. Live-line water cleaning may be affected by contaminants and salt deposits, resulting in incomplete cleaning, and in humid environments, it can also be harmful to personnel. Live-line electric blowing cleaning may cause secondary contamination of insulators by the blown-out dust, and excessive air pressure may blow off equipment components, affecting power transmission safety. Live-line driven chemical cleaning suffers from problems such as the heavy sweeper, making operation inflexible and creating cleaning blind spots. It is also ineffective for non-vertically suspended insulators. Additionally, placing the electric motor close to high-voltage equipment during operation can affect the safe clearance of the high-voltage equipment, posing a safety hazard.

[0005] It is evident that existing insulator surface cleaning methods have many shortcomings in terms of safety, cleaning effect, applicability, and cost. There is an urgent need to develop an efficient, safe, environmentally friendly, and energy-saving insulator surface cleaning method to meet the growing reliability requirements of the power system. Summary of the Invention

[0006] The main objective of this invention is to provide an all-directional wind-driven cleaning device for column insulators, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A wind-driven cleaning device for post insulators includes a rotating mechanism, a wind-driven assembly, and a brush assembly.

[0009] The rotating mechanism includes

[0010] The inner cover is fixedly fitted onto the insulating post of the post insulator;

[0011] The outer shell is rotatably fitted over the inner cover and connected to the inner cover by a bearing. The outer shell has a bottom on the side away from the insulating disc, and a connecting cylinder hole is opened in the middle of the bottom.

[0012] A connecting cylinder, one end of which is fixedly inserted into the hole of the connecting cylinder;

[0013] The omnidirectional drive component includes

[0014] A regular polyhedron is fixedly sleeved on the connecting cylinder. Each face of the regular polyhedron is fixed with an arc-shaped shell by a number of guide plates. The guide plates are located between the face of the regular polyhedron and the arc-shaped shell to form a number of channels. The height of the guide plates gradually decreases along the extension direction so that the air inlet of the channel is larger than the air outlet.

[0015] When wind passes through the channel, a pressure difference is generated between the air inlet and the air outlet. The pressure difference generates a thrust from the air inlet to the air outlet. The orientation of the channel on each face of the regular polyhedron is determined by the position of the face. Wind from any direction can generate thrust through the corresponding channel and drive the regular polyhedron to rotate in a determined direction of rotation.

[0016] The brush assembly includes

[0017] The brush rod has one end fixedly connected to the outer wall of the housing, and the other end extends to the outside of the insulating disc of the post insulator;

[0018] The brush bristles are fixed to the end of the brush handle away from the outer casing and are embedded between multiple insulating discs.

[0019] Preferably, the regular polyhedron is a regular icosahedron, and the connecting cylinder passes through the left and right vertices of the regular icosahedron. On the right side of the regular icosahedron, the channel on face A, which intersects with the right vertex, is arranged counterclockwise, and its air outlet faces the radial direction of the connecting cylinder. The channel on face B, which intersects with face A, is arranged counterclockwise, and its air outlet faces the axial direction of the connecting cylinder. Conversely, on the left side of the regular icosahedron, the channel on face C, which intersects with the left vertex, is arranged clockwise, and its air outlet faces the radial direction of the connecting cylinder. The channel on face D, which intersects with face C, is arranged clockwise, and its air outlet faces the axial direction of the connecting cylinder.

[0020] Preferably, the regular polyhedron has a hollow internal structure, and its inner wall is connected to the middle of the connecting cylinder by a number of support rods.

[0021] Preferably, the inner cover has a bottom on the side away from the insulating disc, and the outer side of the bottom cover and the inner side of the bottom cover are provided with corresponding annular ball grooves, with a number of balls in the two annular ball grooves.

[0022] Preferably, there are several brush assemblies, which are fixed to the outer wall of the housing at equal circumferential intervals. The lengths of the brush handles of the several brush assemblies are not the same, so that several corresponding bristles are respectively embedded between multiple insulating discs in different areas.

[0023] Preferably, the bristles are fan-shaped.

[0024] This invention provides an all-directional wind-driven cleaning device for post-type insulators, which has the following beneficial effects:

[0025] 1. Each face of the regular polyhedron in this device is fixed with an arc-shaped shell by several guide plates. The guide plates are located between the face of the regular polyhedron and the arc-shaped shell, forming several channels. The height of the guide plates gradually decreases along the extension direction so that the air inlet of the channel is larger than the air outlet. When the air passes through the channel, a pressure difference is generated between the air inlet and the air outlet. The pressure difference generates a thrust from the air inlet to the air outlet. Furthermore, the direction of the channel on each face of the regular polyhedron is oriented according to the position of the face. Air from any direction can generate thrust through the corresponding channel to drive the regular polyhedron to rotate in a determined direction of rotation.

[0026] 2. In use, wind from any direction can generate thrust through the corresponding channels, driving the regular polyhedron to rotate in a defined direction. As the polyhedron rotates, the connecting cylinder drives the outer casing to rotate, which in turn drives the brush rod to rotate, cleaning the dirt between the insulating discs through the brush bristles. This device is driven by natural wind power, consuming no additional electricity, achieving green cleaning, energy saving, and environmental protection. It also eliminates the need for manual labor, saving significant manpower, reducing cleaning costs, and minimizing safety hazards. Furthermore, this device does not require power outages during cleaning; it can clean post-type insulators with natural wind, offering high cleaning efficiency and ensuring that the post-type insulators maintain optimal insulation performance over the long term.

[0044] Reference Figure 1 The post-type insulator 2 includes an insulating post 21 and a plurality of insulating discs 22, wherein the plurality of insulating discs 22 are fixedly sleeved on the insulating post 21.

[0045] Reference Figure 1-7The present invention provides an all-wind-driven cleaning device 1 for column insulators, including a rotating mechanism 11, an all-wind-driven assembly 12 and a brush assembly 13;

[0046] The rotating mechanism 11 includes

[0047] The inner cover 111 is fixedly sleeved on the insulating post 21 of the post insulator 2;

[0048] The outer shell 113 is rotatably sleeved outside the inner cover 111 and is connected to the inner cover 111 by a bearing 112. The outer shell 113 has a shell bottom 119 on the side away from the insulating disc 22, and a connecting cylinder hole 115 is opened in the middle of the shell bottom 119.

[0049] One end of the connecting cylinder 114 is fixedly inserted into the connecting cylinder hole 115;

[0050] The all-wind-direction drive component 12 includes

[0051] A regular polyhedron 124 is fixedly sleeved on the connecting cylinder 114. An arc-shaped shell 121 is fixed on each face of the regular polyhedron 124 by a plurality of guide plates 122. The plurality of guide plates 122 are located between the face of the regular polyhedron 124 and the arc-shaped shell 121, forming a plurality of channels 123. The height of the guide plates 122 gradually decreases along the extension direction so that the air inlet of the channel 123 is larger than the air outlet.

[0052] When wind passes through the channel 123, a pressure difference is generated between the air inlet and the air outlet. The pressure difference generates a thrust from the air inlet to the air outlet. The orientation of the channel 123 on each face of the regular polyhedron 124 is oriented according to the position of the face. Wind from any direction can generate a thrust through the corresponding channel 123 to push the regular polyhedron 124 to rotate in a determined rotation direction.

[0053] The brush assembly 13 includes

[0054] The brush rod 132 has one end fixedly connected to the outer wall of the housing 113, and the other end extends to the outside of the insulating disc 22 of the post insulator 2.

[0055] Brush bristles 131 are fixed to the end of the brush rod 132 away from the outer casing 113, and the brush bristles 131 are embedded between a plurality of insulating discs 22.

[0056] The following provides a further explanation using a specific implementation plan, for reference only. Figure 3-6The regular polyhedron 124 is a regular icosahedron. The connecting cylinder 114 passes through the left and right vertices of the regular icosahedron. On the right side of the regular icosahedron, the channel 123 on the face A intersecting the right vertex is arranged counterclockwise, with its air inlet facing the radial direction of the connecting cylinder 114. The channel 123 on the face B intersecting face A is arranged counterclockwise, with its air inlet facing the axial direction of the connecting cylinder 114. Conversely, on the left side of the regular icosahedron, the channel 123 on the face C (not shown) intersecting the left vertex is arranged clockwise, with its air inlet facing the radial direction of the connecting cylinder 114. The channel 123 on the face D intersecting face C is arranged clockwise, with its air inlet facing the axial direction of the connecting cylinder 114.

[0057] When this device is in use, when vertical and oblique winds blow towards the device from the right side of the icosahedron, the wind passes through the channels 123 on each face A, creating a pressure difference between the air inlet and outlet. This pressure difference generates a thrust from the air inlet to the outlet, pushing the icosahedron to rotate counterclockwise. When horizontal and oblique winds blow towards the device, the wind passes through the channels 123 on each face B, creating a pressure difference between the air inlet and outlet. This pressure difference generates a thrust from the air inlet to the outlet, similarly pushing the icosahedron to rotate counterclockwise.

[0058] On the left side of the icosahedron, when vertical and oblique winds blow towards the device, the wind passes through the channels 123 on each face C, creating a pressure difference between the air inlet and outlet. This pressure difference generates a thrust from the air inlet to the outlet, pushing the icosahedron to rotate in a clockwise direction. When horizontal and oblique winds blow towards the device, the wind passes through the channels 123 on each face D, creating a pressure difference between the air inlet and outlet. This pressure difference generates a thrust from the air inlet to the outlet, similarly pushing the icosahedron to rotate in a clockwise direction.

[0059] It should be noted that the icosahedron rotates counterclockwise on its right side and clockwise on its left side. These counterclockwise and clockwise rotations are merely different in their observed directions; in reality, the icosahedron rotates in the same definite direction. This embodiment orients the channels 123 on each face of the icosahedron, allowing wind from any direction to generate thrust through the corresponding channels 123, thus propelling the icosahedron to rotate in a defined direction.

[0060] On each face of the regular polyhedron 124, an arc-shaped shell 121 is fixed by several guide plates 122. The guide plates 122 are located between the face of the regular polyhedron 124 and the arc-shaped shell 121, forming several channels 123. The height of the guide plates 122 gradually decreases along the extension direction so that the air inlet of the channel 123 is larger than the air outlet. When the air passes through the channel 123, a pressure difference is generated between the air inlet and the air outlet. The pressure difference generates a thrust from the air inlet to the air outlet. Furthermore, the orientation of the channel 123 on each face of the regular polyhedron 124 is oriented according to the position of the face. Air from any direction can generate thrust through the corresponding channel 123 to drive the regular polyhedron 124 to rotate in a determined rotation direction.

[0061] When in use, wind from any direction can generate thrust through the corresponding channel 123 to drive the regular polyhedron 124 to rotate in a determined direction of rotation. When the regular polyhedron 124 rotates, it drives the outer shell 113 to rotate through the connecting cylinder 114, which in turn drives the brush rod 132 to rotate. The brush bristles 131 clean the dirt between the insulating discs 22.

[0062] This device is driven by natural wind power, consumes no additional electricity, achieves green cleaning, energy saving and environmental protection, and does not require manual operation, saving a lot of manpower, reducing cleaning costs, and also reducing safety hazards. In addition, the device does not require power outages when cleaning, and can clean the post insulator 2 in the presence of natural wind, with high cleaning efficiency, which can ensure that the post insulator 2 is in the best insulation performance for a long time.

[0063] As a preferred implementation scheme, refer to Figure 3 The regular polyhedron 124 has an internal hollow structure to reduce its own weight and facilitate rotation under the drive of wind. The inner wall is connected to the middle of the connecting cylinder 114 by several support rods 125 to ensure the connection strength between the regular polyhedron 124 and the connecting cylinder 114.

[0064] As a preferred implementation scheme, refer to Figure 3 The inner cover 111 has a cover bottom 118 on the side away from the insulating disc 22. The outer side of the cover bottom 118 and the inner side of the shell bottom 119 are provided with corresponding annular ball grooves 117, and there are a number of balls 116 in the two annular ball grooves 117.

[0065] When the outer shell 113 rotates on the inner cover 111 via the bearing 112, the shell bottom 119 is also supported on the cover bottom 118 via a number of balls 116. The design of the cover bottom 118, shell bottom 119, and balls 116 increases the support area and strength of the outer shell 113 and the inner cover 111, ensuring stable rotation of the outer shell 113 on the inner cover 111. In this embodiment, the bearing 112 is preferably a roller bearing.

[0066] As a preferred implementation scheme, refer to Figure 1-2 The brush assembly 13 comprises several units, which are fixed to the outer wall of the housing 113 at equal intervals around their circumference. The lengths of the brush handles 132 of the several brush assemblies 13 are not equal, so that several corresponding bristles 131 are respectively embedded between multiple insulating discs 22 in different areas.

[0067] The cleaning area of ​​the post insulator 2 is covered by several bristles 131, with each bristle 131 responsible for cleaning one area. This allows for flexible arrangement of each brush assembly 13 according to the shape and surface characteristics of the post insulator 2, enabling the bristles 131 to better conform to the surface of the post insulator 2 for cleaning, avoiding cleaning dead corners, and ensuring that each area is thoroughly cleaned. In this embodiment, there are three brush assemblies 13.

[0068] Of course, for the sake of structural simplicity, one or more long brush assemblies covering the entire cleaning area can also be set up.

[0069] As a preferred implementation scheme, refer to Figure 7 The bristles 131 are fan-shaped, which increases the contact area between the bristles 131 and the post insulator 2, resulting in better cleaning.

[0070] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
