Description

Technical Field

[0001] This utility model belongs to the field of insulator technology, and specifically relates to an insulator self-cleaning device. Background Technology

[0002] Insulators, commonly known as porcelain insulators, are components used to support conductors and maintain their insulation, widely used in overhead power line engineering. They are not only insulators but also crucial insulation controls, playing an indispensable role in overhead transmission lines. Insulators must be able to withstand various electromechanical stresses caused by environmental and electrical load changes; otherwise, they will fail to fulfill their important function, thus affecting the overall performance and service life of the line. In the past, insulators were mainly installed on utility poles. With technological advancements, now many disc-shaped insulators are also suspended at one end of high-voltage power line towers. These insulators, typically made of glass or ceramic, are designed to increase creepage distance and are therefore also called insulators.

[0003] During the operation of high-voltage transmission lines, dust, bird droppings, and other contaminants often accumulate on the surface of insulator strings. These contaminants can easily form leakage paths, leading to flashover of the insulator strings and threatening the stable operation of the power system.

[0004] Currently, the main methods for cleaning insulator strings are manual cleaning and high-pressure water rinsing. However, these methods are relatively inefficient. Utility Model Content

[0005] In view of this, the present invention provides an insulator self-cleaning device to solve the problem that the existing technology mainly uses manual cleaning and high-pressure water rinsing to clean insulators, which is relatively inefficient.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A self-cleaning device for insulators includes an insulator comprising a column and skirts. A mounting base is rotatably connected to the top of the column. A connecting plate is provided on the top of the mounting base, and the connecting plate is radially arranged along the column. A wind cap is provided at the end of the connecting plate away from the column, and the opening of the wind cap is parallel to the column. An extension rod is provided on the side wall of the mounting base, and a vertical shaft is connected to the end of the extension rod away from the column. The vertical shaft is located on the outer side of the skirts. First scraper strips are respectively attached to the bottom and top of two adjacent skirts, and the end of the first scraper strip away from the column is sleeved on the vertical shaft.

[0008] In this technical solution, it should be noted that the cross-section of the mounting base is circular, and the mounting base is rotatably connected to the column through a bearing. The bearing is an important component in modern mechanical equipment. Its main function is to support the rotating mechanical body, reduce the coefficient of friction during its movement, and ensure its rotational accuracy. The connecting plates have a certain curvature, and there are three in total. The three connecting plates are set at 120-degree intervals along the circumference of the mounting base. The wind cap is a hollow hemispherical shape. In this solution, the specific principle is as follows: after the wind blows on the wind-facing surface (opening position) of the wind cap, it drives the mounting base to rotate. After the mounting base rotates, it drives the vertical shaft connected to the extension rod to rotate. The rotation of the vertical shaft drives the first scraper connected to it to rotate. After the first scraper rotates, it cleans the dirt on both ends of the umbrella skirt. In summary, in this utility model, through the set mounting base, vertical shaft, wind cap, and first scraper, the dirt on both ends of the umbrella skirt can be cleaned by natural wind without manual cleaning. Secondly, in this utility model, the connecting plates connected to the wind cap are set along the radial direction of the mounting base. Compared with the vertical direction, the wind cap can drive the mounting base to rotate when subjected to less wind force.

[0009] Preferably, the two first scraper strips located at the bottom and top of two adjacent umbrella skirts are connected by an elastic member; the elastic member includes a cylinder respectively disposed at the bottom and top of the two first scraper strips, and a first spring connecting the bottom of the two cylinders.

[0010] In this technical solution, it should be noted that the material used for the first spring is mostly circular in cross-section, and the spring is generally of equal pitch with a certain gap between the coils. When subjected to external load, the spring contracts and deforms, storing deformation energy. In addition, the cylinder is located in the middle of the first scraper. The first spring applies pressure to the two scrapers towards the corresponding umbrella skirt through the two cylinders, so that the two first scrapers can better fit with the umbrella skirt, thereby improving cleaning efficiency.

[0011] Preferably, the top and bottom of the first scraper are each provided with a cleaning brush.

[0012] In this technical solution, it should be noted that the cleaning brush is elastic. Due to the pressure of the first spring, the cleaning brush will press against the corresponding umbrella skirt, and the outer contour of the cleaning brush will fit the umbrella skirt.

[0013] Preferably, a second scraper and a third scraper are also fitted on the vertical axis, the second scraper contacting the top of the umbrella skirt located at the top position, and the third scraper contacting the bottom of the umbrella skirt located at the bottom position.

[0014] In this technical solution, it should be noted that the second and third scraper strips are mainly used to clean the top and bottom skirts of the insulator. Springs are also provided on the second and third scraper strips to press them together.

[0015] Preferably, a vertical rod parallel to the vertical axis is provided on one side, and the first scraper is sleeved on the vertical rod.

[0016] In this technical solution, it should be noted that the vertical rod is used to limit the first scraper. Since the first scraper is connected to both the vertical rod and the vertical axis, the scraper can only move vertically along the vertical rod and the vertical axis, and cannot rotate around the vertical axis or the vertical rod as the center.

[0017] Preferably, the extension rod is provided with a male buckle, and the mounting base is provided with a female buckle. The extension rod is detachably connected to the mounting base through the cooperation of the male and female buckles.

[0018] In this technical solution, it should be noted that the male and female fasteners are used to enable the rapid installation of the extension rod and the insulator (i.e., the rapid installation of the cleaning device and the insulator).

[0019] Preferably, the female buckle includes two slots located on the upper and lower sides of the end of the extension rod, and the side wall of the mounting base has a groove for inserting the end of the extension rod, the groove having mounting slots opposite to the two slots; the male buckle includes inserts located in the two mounting slots respectively, the inserts being connected to the mounting slots via a second spring, and one end of the inserts extending outside the mounting slots. The end of the insert facing the extension rod has a guide surface, the guide surface being inclined.

[0020] In this technical solution, it should be noted that when the cleaning device needs to be installed, the mounting base is first installed on the top of the column, then each first scraper is abutted against the corresponding umbrella skirt, and then the extension rod is inserted into the groove in the mounting base. During the process of inserting the extension rod into the groove, the extension rod will first contact the first guide surface of the insert block. Since the first guide surface is inclined, the pressure of the extension rod on the first guide surface will be distributed in the vertical direction, causing the insert block to gradually retract into the mounting groove. When the slot on the extension rod is aligned with the mounting groove in the groove, the insert block is reset by the elastic force of the second spring and inserted into the slot, so that the extension rod is fixed, thus completing the installation of the cleaning component.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, the mounting base, vertical shaft, wind cap, and first scraper can be set to clean the dirt on both ends of the umbrella skirt by natural wind, without the need for manual cleaning. Secondly, in this utility model, the connecting plate connected to the wind cap is set radially along the mounting base, which, relative to the vertical, allows the wind cap to drive the mounting base to rotate when subjected to less wind force.

[0023] 2. In this utility model, the cylinder is located in the middle of the first scraper, and the first spring applies pressure to the two scrapers towards the corresponding umbrella skirt through the two cylinders, so that the two first scrapers can better fit with the umbrella skirt, thereby improving cleaning efficiency;

[0024] 3. In this utility model, when the cleaning device needs to be installed, the mounting base is first installed on the top of the column, then each first scraper is abutted against the corresponding umbrella skirt, and then the extension rod is inserted into the groove in the mounting base. During the process of inserting the extension rod into the groove, the extension rod will first contact the first guide surface of the insert block. Since the first guide surface is inclined, the pressure of the extension rod on the first guide surface will be decomposed into the vertical direction, so that the insert block gradually retracts into the mounting groove. When the slot on the extension rod is aligned with the mounting groove in the groove, the insert block is reset by the elastic force of the second spring and inserted into the slot, so that the extension rod is fixed, thus completing the quick installation of the cleaning component.

[0036] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Example 1

[0037] like Figures 1-4As shown in the figure, this utility model discloses a self-cleaning device for insulators. The insulator includes a column 1 and a skirt 2. A mounting base 3 is rotatably connected to the top of the column 1. A connecting plate 4 is provided on the top of the mounting base 3. The connecting plate 4 is arranged radially along the column 1. A wind cap 5 is provided at the end of the connecting plate 4 away from the column 1. The opening of the wind cap 5 is parallel to the column 1. An extension rod 6 is provided on the side wall of the mounting base 3. A vertical shaft 7 is connected to the end of the extension rod 6 away from the column 1. The vertical shaft 7 is located on the outside of the skirt 2. First scraper strips 8 are respectively attached to the bottom and top of two adjacent skirts 2. The end of the first scraper strip 8 away from the column 1 is sleeved on the vertical shaft 7. It should be noted that the cross-section of the mounting base 3 is circular. The mounting base 3 is rotatably connected to the column 1 through a bearing. Bearings are an important component in modern mechanical equipment. Its main function is to support the rotating mechanical body, reduce the coefficient of friction during its movement, and ensure its rotational accuracy. The connecting plate 4 has a certain curvature, and there are three of them. The three connecting plates 4 are set at 120-degree intervals along the circumference of the mounting base 3. The wind cap 5 is a hollow hemispherical shape. In this solution, the specific principle is as follows: after the wind blows on the wind-facing surface (opening position) of the wind cap 5, it drives the mounting base 3 to rotate. After the mounting base 3 rotates, it drives the vertical shaft 7 connected to the extension rod 6 to rotate. The rotation of the vertical shaft 7 drives the first scraper 8 connected to it to rotate. After the first scraper 8 rotates, it cleans the dirt on both ends of the umbrella skirt 2. In summary, in this utility model, through the mounting base 3, vertical shaft 7, wind cap 5 and first scraper 8, the dirt on both ends of the umbrella skirt 2 can be cleaned by natural wind without manual cleaning. Secondly, in this utility model, the connecting plate 4 connected to the wind cap 5 is set along the radial direction of the mounting base 3. Compared with the vertical direction, the wind cap 5 can drive the mounting base 3 to rotate when subjected to less wind force.

[0038] like Figure 3 As shown, in this embodiment, the two first scraper strips 8 located at the bottom and top of two adjacent umbrella skirts 2 are connected by an elastic element. The elastic element includes a cylinder 82 respectively disposed at the bottom and top of the two first scraper strips 8, and a first spring 83 connecting the bottoms of the two cylinders 82. It should be noted that the material used for the first spring 83 is mostly circular in cross-section, and the spring is generally of equal pitch with a certain gap between the coils. When subjected to external load, the spring contracts and deforms, storing deformation energy. In addition, the cylinder 82 is located in the middle of the first scraper strip 8, and the first spring 83 applies pressure to the two scraper strips towards the corresponding umbrella skirt 2 through the two cylinders 82, so that the two first scraper strips 8 can better fit with the umbrella skirt 2, thereby improving cleaning efficiency.

[0039] like Figure 3As shown, in this embodiment, the top and bottom of the first scraper 8 are respectively provided with cleaning brushes 81. It should be noted that the cleaning brushes 81 are elastic. Due to the pressure of the first spring 83, the cleaning brushes 81 will press against the corresponding umbrella skirt 2, and the outer contour of the cleaning brushes 81 will fit the umbrella skirt 2.

[0040] like Figure 2 As shown, in this embodiment, a second scraper 9 and a third scraper 10 are also sleeved on the vertical shaft 7. The second scraper 9 contacts the top of the umbrella skirt 2 located at the top position, and the third scraper 10 contacts the bottom of the umbrella skirt 2 located at the bottom position. It should be noted that the second scraper 9 and the third scraper 10 are mainly used to clean the top and bottom umbrella skirts 2 of the insulator. Springs are also provided on the second scraper 9 and the third scraper 10 to press them together.

[0041] like Figure 2 As shown, in this embodiment, a vertical rod 11 parallel to the vertical shaft 7 is provided on one side, and the first scraper 8 is sleeved on the vertical rod 11. It should be noted that the vertical rod 11 is used to limit the first scraper 8. Since the first scraper 8 is connected to both the vertical rod 11 and the vertical shaft 7, the scraper can only move vertically along the vertical rod 11 and the vertical shaft 7, and cannot rotate around the vertical shaft 7 or the vertical rod 11. Example 2

[0042] like Figure 4 As shown, this embodiment is largely the same as the previous embodiment, except that the extension rod 6 is provided with a male buckle and the mounting base 3 is provided with a female buckle. The extension rod 6 is detachably connected to the mounting base 3 through the cooperation of the male and female buckles. It should be noted that the male and female buckles are used to achieve quick installation of the extension rod 6 and the insulator (i.e., quick installation of the cleaning device and the insulator).

[0043] like Figure 4As shown, in this embodiment, the female buckle includes two slots 61 located on the upper and lower sides of the end of the extension rod 6. The side wall of the mounting base 3 is provided with a groove 35 for the end of the extension rod 6 to be inserted. The groove 35 is provided with mounting slots 31 opposite to the two slots 61. The male buckle includes insert blocks 33 located in the two mounting slots 31 respectively. The insert blocks 33 are connected to the mounting slots 31 by a second spring 32, and one end of the insert blocks 33 extends outside the mounting slots 31. The end of the insert block 33 facing the extension rod 6 is provided with a guide surface 34, which is inclined. It should be noted that when installing this cleaning device, firstly, the mounting base 3 is installed on the top of the column 1, then each of the first scraper strips 8 is abutted against the corresponding umbrella skirt 2, and then the extension rod 6 is inserted into the groove 35 in the mounting base 3. During the process of inserting the extension rod 6 into the groove 35, the extension rod 6 will first contact the first guide surface 34 of the insert block 33. Since the first guide surface 34 is an inclined surface, the pressure of the extension rod 6 on the first guide surface 34 will be distributed in the vertical direction, causing the insert block 33 to gradually retract into the mounting groove 31. When the slot 61 on the extension rod 6 is aligned with the mounting groove 31 in the groove 35, the insert block 33 is reset by the elastic force of the second spring 32 and inserted into the slot 61, so that the extension rod 6 is fixed, thus completing the installation of the cleaning component.

[0044] The working principle of this utility model is as follows:

[0045] When the cleaning device needs to be installed, first install the mounting base 3 on the top of the column 1, then place each first scraper 8 against the corresponding umbrella skirt 2, and then insert the extension rod 6 into the groove 35 in the mounting base 3. During the process of inserting the extension rod 6 into the groove 35, the extension rod 6 will first contact the first guide surface 34 of the insert block 33. Since the first guide surface 34 is inclined, the pressure of the extension rod 6 on the first guide surface 34 will be distributed in the vertical direction, so that the insert block 33 gradually retracts into the mounting groove 31. When the slot 61 on the extension rod 6 is aligned with the mounting groove 31 in the groove 35, the insert block 33 is reset by the elastic force of the second spring 32 and inserted into the slot 61, so that the extension rod 6 is fixed, thus completing the installation of the cleaning component.

[0046] When the windward side (opening position) of the hood 5 is blown by the wind, it causes the mounting base 3 to rotate. After the mounting base 3 rotates, it causes the vertical shaft 7 connected to the extension rod 6 to rotate. The rotation of the vertical shaft 7 causes the first scraper 8 connected to it to rotate. After the first scraper 8 rotates, it cleans the dirt on both ends of the umbrella skirt 2.

[0047] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0048] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention.
