Description

Technical Field

[0001] This invention relates to the field of insulator technology, specifically a self-cleaning suspension insulator. Background Technology

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding component, capable of withstanding voltage and mechanical stress. Insulators come in many types and shapes. While different types of insulators vary considerably in structure and appearance, they all consist of two main parts: insulating components and connecting hardware. Insulators are a special type of insulating control that plays a crucial role in overhead transmission lines. In the early days, insulators were mostly used on utility poles, but they gradually evolved into the practice of hanging many disc-shaped insulators at one end of high-voltage power line towers to increase creepage distance; these are typically made of glass or ceramic.

[0003] Although insulators are mostly installed at high locations, dust still easily accumulates on their surfaces. Once dust accumulates on the insulator surface, it can easily mix with rainwater and form pathways, which greatly reduces the insulation performance of the insulator. It can also cause flashover and rain flashover, posing safety hazards. Therefore, it is necessary to clean the insulator discs regularly. Currently, the most common method is to use high-pressure water guns for washing, which is time-consuming and labor-intensive. The surface of the insulator will get dirty again after a period of time after washing, and the cleaning effect is not ideal. There is room for improvement in the cleaning method of insulators. Summary of the Invention

[0004] The purpose of this invention is to provide a self-cleaning suspension insulator to solve the problems mentioned in the background art, such as the time-consuming and laborious process of washing with a high-pressure water gun and the problem that the insulator will get dirty again after being washed for a period of time.

Detailed Implementation

[0034] The following embodiments will describe the present invention in detail with reference to the accompanying drawings. In the drawings or description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this invention are merely illustrative and not intended to limit the scope of the invention. Any obvious modifications or changes made to this invention do not depart from the spirit and scope of the invention.

[0035] Please see Figures 1-2In this embodiment of the invention, a self-cleaning suspension insulator includes an insulator disc 1 and an insulator post 2. One insulator is connected to another insulator through the insulator post 2. The insulator post 2 includes an upper post 21 and a lower post 22, which are respectively arranged on the upper and lower sides of the insulator disc 1. A condensation cover 7, a water cylinder 6, and a water collection cover 3 are arranged sequentially from top to bottom between the lower post 22 and the insulator disc 1. The condensation cover 7 is fixed at the bottom of the insulator disc 1, the water collection cover 3 is fixed at the top of the lower post 22, and the water cylinder 6 is fixed between the condensation cover 7 and the water collection cover 3. The insulator disc 1, the condensation cover 7, and the water collection cover 3 are arranged opposite each other, and the centers of the three are located on the same straight line. The diameter of the insulator disc 1 is larger than the diameter of the water collection cover 3, and the diameter of the water collection cover 3 is larger than the diameter of the condensation cover 7. A fan blade 5 and a cleaning device 4 are arranged between the upper post 21 and the insulator disc 1. The cleaning device 4 is located on the lower side of the fan blade 5.

[0036] In this embodiment, a fan blade 5 and a cleaning device 4 are provided on the upper side of the insulator disc 1. The fan blade 5 can drive the cleaning device 4, which can clean the dust on the upper surface of the insulator disc 1. A condensation cover 7 is provided on the lower side of the insulator disc 1, and a water collection cover 3 is provided on the lower side of the condensation cover 7. The condensation cover 7 can condense dew in the air, and the dew drips into the water collection cover 3. A through hole is provided at the bottom of the water cylinder 6, and the dew in the water collection cover 3 can flow into the water cylinder 6 for storage. The water cylinder 6 is also provided with a pipe, which can draw out the dew in the cylinder and let it flow out from the top of the insulator disc 1. The disc surface is cleaned by water flow. The two cleaning methods are used in combination to adapt to the self-cleaning work of the insulator under different seasons and different climates.

[0037] Please see Figures 4-6 The water cylinder 6 is a cylindrical structure with openings at both the top and bottom. The water cylinder 6 is made of heat-conducting material. Multiple water inlet holes 64 are evenly opened on the inner wall of the bottom end of the water cylinder 6. Each of the multiple water inlet holes 64 is equipped with a one-way valve. The water accumulated in the water collection hood 3 flows into the water cylinder 6 for storage through the water inlet holes 64. A suction pipe 62 is fixed in the middle of the inside of the water cylinder 6. The bottom end of the suction pipe 62 is open and its top end is closed. The bottom opening of the suction pipe 62 is higher than the bottom plane of the water cylinder 6. An impeller 65 is rotatably connected to the bottom opening of the suction pipe 62.

[0038] Multiple capillary tubes 61 are evenly arranged around the inside of the water cylinder 6. The multiple capillary tubes 61 are connected to the suction pipe 62 through the connecting pipe 63. The capillary tubes 61 and the suction pipe 62 are interconnected through the connecting pipe 63. Each of the multiple connecting pipes 63 is equipped with a one-way valve, so that the water in the suction pipe 62 can only flow into the capillary tubes 61 in one direction. The bottom ends of the multiple capillary tubes 61 are flush with the bottom ends of the suction pipe 62. The top ends of the multiple capillary tubes 61 penetrate the top inner wall of the condenser cover 7, the top inner wall of the insulator disc 1, and the side wall of the mounting cylinder 11 and extend to one side of the top inclined surface of the insulator disc 1.

[0039] In this embodiment, water is collected and stored in a water cylinder 6. The water source can be dew or rainwater. A capillary tube 61 is installed inside the water cylinder 6. The capillary tube can achieve automatic climbing and precise delivery of liquid by means of surface tension and capillary effect. At the same time, a suction pipe 62 is installed inside the water cylinder 6. An impeller 65 is installed in the suction pipe 62. By rotating the impeller 65, water in the water cylinder 6 is drawn into the suction pipe 62 and transported to the capillary tube 61 through the connecting pipe 63. The top end of the capillary tube 61 extends to the top slope of the insulator disc 1. The water in the capillary tube 61 flows outward through the opening at its top to the upper surface of the insulator disc 1. The capillary tubes 61 are evenly distributed, so that the water in the capillary tubes 61 can also flow evenly to the upper surface of the insulator disc 1, thereby washing away the dust on the upper surface of the insulator disc 1.

[0040] Please see Figure 3 and Figure 7 Both the water collecting cover 3 and the condenser cover 7 are bowl-shaped structures, and are arranged opposite each other. Both the water collecting cover 3 and the condenser cover 7 are made of insulating materials. The inner arc surface of the water collecting cover 3 is coated with a layer of reflective paint to form a reflective coating 31. The reflective coating 31 can reflect sunlight onto the water cylinder 6. The water cylinder 6 is made of heat-conducting material. When sunlight shines on the water cylinder 6, the water cylinder 6 will be heated, and the water inside will also be heated. After the water is heated, it will expand to a certain extent. At this time, the tension between the water and the capillary tube 61 will also increase, and the water will flow more easily in the capillary tube 61 and eventually flow out. When the impeller 65 rotates at a low speed or does not rotate, as long as there is sufficient light, the water in the water cylinder 6 can also flow out through the capillary tube 61 and thus wash the dust on the upper surface of the insulator disc 1.

[0041] A heat dissipation foil 71 is fixed on the inner arc surface of the condenser cover 7. The heat dissipation foil 71 is made of a material with good heat dissipation performance. In seasons or environments with high air humidity, the temperature is low in the early morning. Water vapor in the air condenses into dew after contacting the heat dissipation foil 71. The dew drips down the inner arc surface of the condenser cover 7 into the water collection cover 3. The water in the water collection cover 3 flows into the water cylinder 6 for storage. When the sun rises and the temperature rises, the water in the water cylinder 6 will flow out through the capillary tube 61 to clean the insulator disc 1.

[0042] Please see Figures 8-12 An installation cylinder 11 is also provided between the upper column 21 and the insulator disc 1. The installation cylinder 11 is a cylindrical structure with open ends. The bottom end of the upper column 21 is fixed to the top end of the installation cylinder 11, and the bottom end of the installation cylinder 11 is fixed to the top end of the insulator disc 1. The fan blade 5 and the cleaning device 4 are respectively sleeved on the upper and lower ends of the installation cylinder 11. A first transmission structure 8 is provided inside the installation cylinder 11 on the side corresponding to the fan blade 5, and a second transmission structure 9 is provided inside the installation cylinder 11 on the side corresponding to the cleaning device 4. Multiple transmission shafts 10 are provided between the first transmission structure 8 and the second transmission structure 9.

[0043] The first transmission structure 8 includes a first connecting ring 81, a first internal gear ring 82 fixed on the inner side of the first connecting ring 81, a plurality of first internal gears 83 meshing with the inside of the first internal gear ring 82, the plurality of first internal gears 83 being rotatably connected inside the mounting cylinder 11, and a transmission gear 84 rotatably connected inside the mounting cylinder 11 at the middle position corresponding to one side of the plurality of first internal gears 83, the transmission gear 84 meshing with the plurality of first internal gears 83 one by one, the first internal gear ring 82, the plurality of first internal gears 83 and the transmission gear 84 cooperating with each other to form a planetary gear structure, which can increase the speed of the transmission gear 84;

[0044] A linkage shaft 13 is fixed on the transmission gear 84. One end of the linkage shaft 13 rotates through the top inner wall of the insulator disc 1, the top inner wall of the condenser cover 7, and the top inner wall of the extraction pipe 62 before extending into the interior of the extraction pipe 62. The bottom end of the linkage shaft 13 is fixedly connected to the rotating shaft of the impeller 65. When the linkage shaft 13 rotates, it will drive the impeller 65 to rotate. When the impeller 65 rotates, it can draw water from the water cylinder 6.

[0045] The second transmission structure 9 includes a second connecting ring 91, a second internal gear ring 92 is fixed on the inner side of the second connecting ring 91, and a plurality of second internal gears 93 are meshed inside the second internal gear ring 92. The plurality of second internal gears 93 are rotatably connected inside the mounting cylinder 11. The plurality of second internal gears 93 are arranged in a one-to-one correspondence with the plurality of first internal gears 83, and the corresponding second internal gears 93 and first internal gears 83 are connected to each other through a transmission shaft 10.

[0046] On the inner wall of the mounting cylinder 11, an annular groove 111 is provided on one side corresponding to the first internal gear ring 82 and the second internal gear ring 92. The first internal gear ring 82 and the second internal gear ring 92 are rotatably connected in the groove 111 on the corresponding side. On the inner wall of the mounting cylinder 11, an annular through groove 112 is provided on one side corresponding to the first connecting ring 81 and the second connecting ring 91. The through groove 112 penetrates the side wall of the mounting cylinder 11. The first connecting ring 81 and the second connecting ring 91 are rotatably connected in the through groove 112 on the corresponding side. The outer walls of the first connecting ring 81 and the second connecting ring 91 extend to the outer edge of the through groove 112. Mounting rings 12 are provided on the upper and lower sides of the two through grooves 112. The mounting rings 12 are T-shaped annular structures.

[0047] The mounting ring 12 is T-shaped and has a T-shaped connecting part on the side facing the first connecting ring 81 or the second connecting ring 91. The inner walls of the first connecting ring 81 and the second connecting ring 91 are provided with T-shaped slots on the side corresponding to the T-shaped connecting part of the mounting ring 12. The T-shaped connecting part is slidably inserted into the T-shaped slot. The side of the mounting ring 12 away from the first connecting ring 81 or the second connecting ring 91 is fixed on the inner wall of the through groove 112. To ensure that the gear ring and the connecting ring can rotate smoothly between the inner walls of the mounting cylinder 11, ball bearings can be provided between the gear ring and the slot 111 and between the connecting ring and the mounting ring 12.

[0048] The connection structure between the first connecting ring 81, the second connecting ring 91, and the mounting cylinder 11 is as follows: Figure 12 As shown, the connecting ring and the inner wall of the mounting cylinder 11 are connected in a snap-fit ​​manner through two mounting rings 12, ensuring that the connecting ring will not fall off the inner wall of the mounting cylinder 11 and thus guaranteeing the stability of the connection.

[0049] The fan blade 5 includes a rotating cylinder located in the middle and multiple blades evenly fixed outside the rotating cylinder. The rotating cylinder of the fan blade 5 is rotatably sleeved on the outside of the mounting cylinder 11 on the side corresponding to the first connecting ring 81, and the inner wall of the rotating cylinder of the fan blade 5 is connected and fixed to the outer wall of the first connecting ring 81. The cleaning device 4 is rotatably sleeved on the outside of the mounting cylinder 11 on the side corresponding to the second connecting ring 91, and the inner wall of the cleaning device 4 is connected and fixed to the outer wall of the second connecting ring 91.

[0050] In this embodiment, when the fan blade 5 rotates, it will drive the first connecting ring 81 to rotate. When the first connecting ring 81 rotates, it will drive the first internal gear ring 82 to rotate. When the first internal gear ring 82 rotates, it will drive the multiple first internal gears 83 inside it to rotate synchronously. The multiple first internal gears 83 drive the multiple second internal gears 93 to rotate through the transmission shaft 10. The second internal gears 93 mesh with the second internal gear ring 92. When the second internal gears 93 rotate, they will drive the second internal gear ring 92 and the second connecting ring 91 to rotate synchronously. The cleaning device 4 is connected to the second connecting ring 91. When the second connecting ring 91 rotates, it will drive the cleaning device 4 to rotate on the upper surface of the insulator disc 1, thereby cleaning the dust on the upper surface of the insulator disc 1.

[0051] At the same time, multiple first internal gears 83 mesh with the transmission gear 84. When the first internal gears 83 rotate, they also drive the transmission gear 84 to rotate. Under the combined drive of multiple first internal gears 83, the transmission gear 84 rotates faster and has a stronger driving force, thus effectively rotating the impeller 65. This allows the impeller 65 to have enough power to draw water from the water tank 6, extract the water from the water tank 6 and spray it onto the upper surface of the insulator disc 1 to wash away the dust on the disc surface. In conjunction with the cleaning device 4, it can effectively remove the dust from the surface of the insulator disc 1.

[0052] Please see Figures 13-14The cleaning device 4 includes an inner ring 41 and an outer ring 42. The inner ring 41 is rotatably sleeved on the outside of the mounting cylinder 11 on one side corresponding to the second connecting ring 91, and the inner side wall of the inner ring 41 is connected and fixed to the outer side wall of the second connecting ring 91. The outer ring 42 is sleeved and fixed on the outside of the inner ring 41. Multiple hinge seats 43 are fixed on the outer edge of the outer ring 42. Each of the multiple hinge seats 43 is hinged to a bracket 44. One end of the bracket 44 can rotate around the hinge seat 43, and a locking structure is provided between the two. The locking structure can be a bolt locking structure, and existing technology can be used.

[0053] Each of the multiple supports 44 has a brush plate 45 below it, and each of the multiple brush plates 45 has bristles 46 at its bottom. The bristles are soft and can be made of materials such as rubber. Multiple telescopic rods 47 are fixed between the brush plate 45 and the corresponding support 44. The two ends of the telescopic rods 47 are fixedly connected to the brush plate 45 and the support 44, respectively. Existing telescopic rods can be used for the telescopic rods 47. Each of the multiple telescopic rods 47 is fitted with a spring 48. The two ends of the spring 48 are fixed to the brush plate 45 and the support 44, respectively. Before use, the angle of the support 44 is pre-adjusted so that the brush plate 45 and the bristles 46 at its bottom are in close contact with the upper surface of the insulator disc 1. The springs 48 can apply downward pressure to the brush plate 45 so that the bristles 46 at its bottom can always be in contact with the disc surface to ensure the cleaning effect.

[0054] Working principle:

[0055] In use, multiple insulator discs 1 are connected in series to form a complete suspension insulator via insulator posts 2. The uppermost post 21 is connected to the utility pole via a parallel hanging plate, and the lowermost post 22 is connected to the cable via a wedge clamp. In daily use, the cleaning of the surface of the insulator disc 1 can be roughly divided into three situations:

[0056] In the first scenario: During rainy weather, rainwater falls directly onto the insulator disc 1, washing away the dust on the disc surface. Simultaneously, under windy conditions, the fan blade 5 rotates. When the fan blade 5 rotates, it drives the first connecting ring 81, the first internal gear ring 82, and multiple first internal gears 83 to rotate synchronously. When the first internal gear 83 rotates, it drives the second internal gear 93 to rotate through the transmission shaft 10. The second internal gear 93 meshes with the second internal gear ring 92. When the second internal gear 93 rotates, it drives the second internal gear ring 92 and the second connecting ring 91 to rotate synchronously. The inner ring 41 of the cleaning device 4 is fixedly connected to the second connecting ring 91. When the second connecting ring 91 rotates, it drives the entire cleaning device 4 to rotate through the inner ring 41. The brush plate 45 and brush bristles 46 in the cleaning device 4 will make circular motions on the upper surface of the insulator disc 1, sweeping away the dust attached to the disc surface. Combined with the rainwater washing, the surface of the insulator disc 1 is cleaned.

[0057] The second scenario: When there is no rain but there is dew, the air humidity is high. When the water vapor in the air encounters the heat dissipation foil 71, it condenses into dewdrops. The dewdrops drip down into the water collection cover 3 and eventually flow into the water cylinder 6 for storage. The water cylinder 6 can also store rainwater. When it rains, some rainwater will fall into the water collection cover 3 under the action of wind. After a certain amount of water is stored in the water cylinder 6, it can be used to wash the insulator disc surface. Specifically, the water in the water cylinder 6 is drawn by the set capillary tube 61. The capillary tube 61 can realize the automatic climbing and precise delivery of liquid by means of surface tension and capillary effect. When the power of the capillary tube 61 to deliver liquid upward is insufficient, the water cylinder 6 is heated by the water collection cover 3 and the reflective coating 31. After the water in the water cylinder 6 is heated, the tension between the water and the capillary tube 61 will increase accordingly, and the water will flow more easily in the capillary tube 61 and eventually flow out.

[0058] Simultaneously, drainage can be assisted by rotating the impeller 65. Specifically, when the fan blade 5 rotates, the linkage shaft 13 is rotated through the cooperation of the first internal gear ring 82, the first internal gear 83, and the transmission gear 84. When the linkage shaft 13 rotates, the impeller 65 at its bottom will also rotate synchronously. The fan blade 5 may rotate clockwise or counterclockwise. Correspondingly, the impeller 65 will also rotate clockwise or counterclockwise. When the impeller 65 rotates clockwise, the water in the water cylinder 6 is sucked into the suction pipe 62 and flows into the capillary tube 61 through the connecting pipe 63. Finally, it flows out from the top opening of the capillary tube 61. When the impeller 65 rotates counterclockwise, the water in the water cylinder 6 no longer flows into the suction pipe 62. The impeller 65 will also apply pressure to the liquid surface inside the cylinder, pushing the water flow into the capillary tube 61. Finally, the water also flows out from the top opening of the capillary tube 61. The stored water is used to rinse the surface of the insulator disc. At the same time, the cleaning device 4 is used to clean the surface of the insulator disc 1.

[0059] The third scenario: There is no rain or dew. In this case, as long as there is wind, the fan blade 5 will rotate. Then, through the cooperation of the first transmission structure 8 and the second transmission structure 9, the cleaning device 4 will rotate, causing the brush plate 45 and the bristles 46 to rotate around the insulator disc to clean the dust.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
