Description

Technical Field

[0001] The invention relates to the technical field of insulators, in particular to a self-cleaning suspension insulator. Background Art

[0002] Insulators are devices installed between conductors at different potentials, or between a conductor and a grounded structure, capable of withstanding voltage and mechanical stress. They come in a wide variety of types and shapes. While their structures and appearances vary significantly, they all consist of two main components: an insulating member and connecting hardware. Insulators are specialized insulating components that play a vital role in overhead transmission lines. In the early days, insulators were primarily used on utility poles. This evolved into a system where multiple disc-shaped insulators, typically made of glass or ceramic, are hung on one end of a high-voltage power tower to increase creepage distance.

[0003] Although insulators are mostly installed at higher positions, dust is still easily attached to their surfaces. Dust attached to the insulator surface is easily mixed with rainwater and forms a path, which greatly reduces the insulation performance of the insulator. It also causes pollution flashover and rain flashover, posing a safety hazard. Therefore, the insulating disk of the insulator needs to be cleaned regularly. The current method is mostly high-pressure water gun washing, which is time-consuming and labor-intensive. The insulator surface will become dirty again within a period of time after washing, and the cleaning effect is not ideal. There is room for improvement in the cleaning method of insulators.

A pipe is also provided in the water cylinder 6, which can extract the dew in the cylinder and flow out from the top of the insulator disk 1, and the disk surface is cleaned by water flow. The two cleaning methods are used in combination to adapt to the self-cleaning work of the insulator in different seasons and different climatic environments.

[0037] See also Figures 4-6 The water cylinder 6 is a cylindrical structure with openings at both ends. The water cylinder 6 is made of heat-conducting material. A plurality of water inlet holes 64 are evenly opened on the inner wall of the bottom end of the water cylinder 6. A one-way valve is installed in each of the plurality of water inlet holes 64. The water accumulated in the water collecting cover 3 flows into the water cylinder 6 for storage in one direction through the water inlet holes 64. A suction pipe 62 is fixed at the middle position inside the water cylinder 6. The bottom end of the suction pipe 62 is an open design and its top end is closed.

[0038] A plurality of capillaries 61 are evenly arranged around the interior of the water cylinder 6. The plurality of capillaries 61 are connected to the extraction tube 62 through a connecting tube 63. The capillaries 61 and the extraction tube 62 are connected to each other through the connecting tube 63. A one-way valve is installed on each of the plurality of connecting tubes 63. The water in the extraction tube 62 can only flow into the capillary tube 61 in one direction. The bottom ends of the plurality of capillaries 61 are flush with the bottom ends of the extraction tube 62. The top ends of the plurality of capillaries 61 pass through the inner wall of the top of the condensation cover 7, the inner wall of the top of the insulator disk 1, and the side wall of the mounting cylinder 11 and extend to one side of the top inclined surface of the insulator disk 1.

[0039] In this embodiment, a water source is collected and stored by a water barrel 6, and the water source can be dew or rainwater. A capillary tube 61 is provided in the water barrel 6.

The capillaries 61 are evenly distributed, so that the water in the capillary tube 61 can also flow evenly to the upper surface of the insulator disk 1, thereby washing away dust on the upper surface of the insulator disk 1.

[0040] See also Figure 3 and Figure 7 , the water collecting cover 3 and the condensation cover 7 are both bowl-shaped structures, and the two are arranged opposite to each other up and down. The water collecting cover 3 and the condensation cover 7 are both made of insulating material. A layer of reflective paint is coated on the inner curved surface of the water collecting cover 3 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 it will also be heated. When the water is heated, it will expand to a certain extent. At this time, the tension between the water and the capillary 61 will also become greater, and the water will flow more easily in the capillary 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 61 and use it to wash away the dust on the surface of the insulator disk 1;

In seasons or environments with high air humidity, the temperature is low in the early morning. The water vapor in the air condenses into dew after contacting the heat dissipation foil 71. The dew drips downward along the inner curved surface of the condensation cover 7 into the water collecting cover 3. The water in the water collecting cover 3 flows into the water cylinder 6 for storage. When the sun rises and the temperature rises, when the sunlight shines on the water cylinder 6, the water in the water cylinder 6 will flow out through the capillary 61 and be used to clean the insulator disk 1.

[0042] See also Figures 8-12 A mounting tube 11 is further provided between the upper column 21 and the insulator disk 1. The mounting tube 11 is a cylindrical structure with openings at both ends.

[0047] The side of the mounting ring 12 facing the first connecting ring 81 or the second connecting ring 91 is T-shaped and is provided with a T-shaped connecting portion. A T-shaped slot is provided on the inner wall of the first connecting ring 81 and the second connecting ring 91 on the side corresponding to the T-shaped connecting portion of the mounting ring 12.

[0050] In this embodiment, when the fan blades 5 rotate, they drive the first connecting ring 81 to rotate. When the first connecting ring 81 rotates, it drives the first inner ring 82 to rotate. When the first inner ring 82 rotates, it drives the multiple first inner gears 83 inside it to rotate synchronously. The multiple first inner gears 83 drive the multiple second inner gears 93 to rotate through the transmission shaft 10. The second inner gears 93 are engaged with the second inner ring 92. When the second inner gears 93 rotate, they drive the second inner 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 drives the cleaning device 4 to rotate on the upper surface of the insulator disk 1, thereby cleaning the dust on the upper surface of the insulator disk 1.

[0051] At the same time, multiple first internal gears 83 are engaged with the transmission gear 84. When the first internal gear 83 rotates, it also drives the transmission gear 84 to rotate. Moreover, the transmission gear 84 is driven by the cooperation of the multiple first internal gears 83 to rotate faster and have a stronger driving force, thereby effectively rotating the impeller 65. The impeller 65 has sufficient power to extract water from the water cylinder 6, and the water in the water cylinder 6 is extracted and sprayed on the upper surface of the insulator disk 1 to wash away the dust on the surface of the disk body. Then, the impeller 65 cooperates with the cleaning device 4 to effectively remove the dust on the surface of the insulator disk 1.

[0052] See also Figures 13-14The cleaning device 4 includes an inner ring 41 and an outer ring 42.

[0053] A brush plate 45 is provided under the multiple brackets 44, and bristles 46 are provided at the bottom of the multiple brush plates 45. The bristles are soft and can be made of rubber or other materials. A plurality of telescopic rods 47 are fixed between the brush plates 45 and the corresponding brackets 44. The two ends of the telescopic rods 47 are fixedly connected to the brush plates 45 and the brackets 44 respectively. The telescopic rods 47 can use existing telescopic rods. The outside of the multiple telescopic rods 47 is provided with a spring 48, and the two ends of the spring 48 are fixed to the brush plate 45 and the bracket 44 respectively. Before use, the angle of the bracket 44 is pre-adjusted so that the brush plate 45 and the bristles 46 at its bottom are close to the upper surface of the insulator disk 1. The provided spring 48 can exert downward pressure on the brush plate 45 so that the bristles 46 at its bottom can always fit on the disk surface to ensure the cleaning effect.

[0054] Working principle:

[0055] During use, multiple insulator discs 1 are connected in series through insulator columns 2 to form a complete suspension insulator. The upper column 21 at the top is connected to the utility pole through a parallel hanging plate, and the lower column 22 at the bottom is connected to the cable through a wedge-shaped wire clamp. During daily use, the cleaning work on the surface of the insulator disc 1 can be roughly divided into three situations:

[0056] The first situation: in rainy weather, rainwater falls directly on the insulator disk 1, washing away the dust on the surface of the disk. At the same time, under windy conditions, the fan blades 5 will rotate. When the fan blades 5 rotate, they will drive the first connecting ring 81, the first inner gear 82 and the multiple first inner gears 83 to rotate synchronously. When the first inner gear 83 rotates, it drives the second inner gear 93 to rotate through the transmission shaft 10. The second inner gear 93 is meshed and connected with the second inner gear 92. When the second inner gear 93 rotates, it drives the second inner gear 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 the bristles 46 in the cleaning device 4 will make a circular motion on the upper surface of the insulator disk 1 to clean the dust attached to the disk surface. Combined with the rainwater flushing, the surface of the insulator disk 1 is cleaned.

[0057] The second situation: when there is dew but no rain, the air humidity is high, and the water vapor in the air condenses into dewdrops after encountering the heat dissipation foil 71. The dewdrops drip downward into the water collecting cover 3 and eventually flow into the water cylinder 6 for storage. The water cylinder 6 can also store rainwater when it rains. When it rains, part of the rainwater will fall into the water collecting 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 disk. Specifically, the water in the water cylinder 6 is absorbed by the provided capillary tube 61. The capillary tube 61 can realize the automatic climbing and precise transportation of the liquid by virtue of surface tension and capillary effect. When the power of the capillary tube 61 to transport the liquid upward is insufficient, the water cylinder 6 is heated by the water collecting 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, making it easier for the water to flow in the capillary tube 61 and eventually flow out.

[0058] At the same time, drainage can also be assisted by rotating the impeller 65. Specifically, when the fan blades 5 rotate, the linkage shaft 13 is rotated through the cooperation of the first inner gear ring 82, the first inner gear 83 and the transmission gear 84. When the linkage shaft 13 rotates, the impeller 65 at the bottom end thereof will also rotate synchronously. The fan blades 5 may rotate clockwise or counterclockwise, and 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, and finally 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, and the impeller 65 will also apply pressure to the liquid surface in the cylinder, pushing the water into the capillary tube 61, and finally the water also flows out from the top opening of the capillary tube 61, and the stored water is used to rinse the insulator disk surface. At the same time, the cleaning device 4 cleans the disk surface to clean the surface of the insulator disk 1.

[0059] The third situation: there is no rain and no dew. In this case, as long as there is wind, the fan blades 5 will rotate, and then the cleaning device 4 will be driven to rotate through the cooperation of the first transmission structure 8 and the second transmission structure 9, so that the brush plate 45 and the bristles 46 rotate around the insulator disk 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 embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0061] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
