Description

Technical Field

[0001] The present invention belongs to the technical field of electrical safety, and particularly relates to a cleaning device and a cleaning system for insulators. Background Art

[0002] High-voltage live cleaning is currently the most important cleaning and maintenance method for in-depth maintenance of electronic, power, and electrical equipment. High-voltage live cleaning includes two aspects: a highly insulating live cleaning liquid and professional cleaning equipment. Currently, the types of cleaning nozzles used in professional cleaning devices are relatively single, mainly fixed linear or water column types, etc., resulting in low cleaning efficiency and high cleaning costs in some specific cleaning scenarios.

[0003] In an application scenario, insulators of power transmission and transformation lines are exposed outdoors for a long time, and dirt in the air will gradually cover the surface of the insulators, damaging the surface insulation of the insulators and causing "flashover" of the insulators, resulting in the shutdown or paralysis of the large power grid. Therefore, the insulators of power transmission and transformation lines need to be cleaned regularly. In the conventional cleaning scheme, the insulators are cylindrical, and the spray gun nozzles used are all "linear", and the liquid fan sprayed is a "linear" plane. The linear plane cannot clean a larger area, so the fan surface cleaned each time is very limited, and the effective cleaning area at one time is 1 / 5 - 1 / 6, and it is necessary to change the angle and perform high-pressure spraying many times.

[0004] For an existing insulator of a power transmission line along a high-speed railway, due to this installation form of the insulator and the fact that the insulator is at a high place, when cleaning with a linear fan surface from the ground, only the lower part and both sides of the insulator can be cleaned, and the severely polluted upper part can hardly be cleaned, and there is still a possibility of a large number of "flashovers" after cleaning, and the problem is not completely solved after spending money. Therefore, how to solve the above problems needs to be solved urgently. Summary of the Invention

[0041] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0043] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0044] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0045] The present invention relates to the application field of electrical safety, specifically to the cleaning application of insulators. In an application scenario, the inventor found that since the nozzles of existing cleaning devices are usually in a "one" shape, only a small local area of the insulator can be cleaned in actual application. For example, Figure 1 As shown, the spraying area B of the existing nozzle for cleaning the insulator A from one angle is only 1 / 5 - 1 / 6. Therefore, it is necessary to spray and clean the insulator A from multiple angles. In this process, not only cleaning resources (cleaning liquid) are wasted, but also the cleaning efficiency is low. In view of this, the inventive concept of this patent application is thus formed. The cleaning device of the present invention can achieve large-area cleaning of the insulator at one time, so as to improve the cleaning efficiency of the cleaning device for the insulator, thereby reducing the maintenance cost of the insulator and improving the safety of electrical applications. This will be specifically described through the following embodiments.

[0046] Embodiment 1

[0047] The first aspect of the present invention provides a cleaning device for insulators. In one embodiment, as Figure 2 and Figure 3 shown, the cleaning device includes an arc-shaped elastic piece 1, a base 2, and a fence 3 arranged around the base 2.

[0048] Specifically, the arc-shaped elastic piece 1 includes a first arc-shaped piece 11 and a second arc-shaped piece 12 fixedly arranged on the base 2, and a spraying channel is formed between the first arc-shaped piece 11 and the second arc-shaped piece 12; a convex structure for extruding the first arc-shaped piece 11 and / or the second arc-shaped piece 12 is arranged on the inner side wall of the surrounding plate 3, that is, the convex structure can extrude the first arc-shaped piece 11, or extrude the second arc-shaped piece 12, or extrude both the first arc-shaped piece 11 and the second arc-shaped piece 12; wherein, the surrounding plate 3 is rotatably arranged on the base 2, a liquid inlet channel 21 communicating with the spraying channel is arranged at the bottom of the base 2, and when the base 2 or the surrounding plate 3 is rotated to a preset position, the convex structure extrudes the first arc-shaped piece 11 and / or extrudes the second arc-shaped piece 12.

[0049] In an application scenario, when the cleaning device needs to be applied, cleaning liquid is input through the liquid inlet channel 21, and then the base 2 is rotated while keeping the surrounding plate 3 stationary, or the surrounding plate 3 is rotated while keeping the base 2 stationary, or when the base 2 and the surrounding plate 3 are relatively rotated to a preset position, the convex structure on the inner side wall of the surrounding plate 3 extrudes the first arc-shaped piece 11 or extrudes the second arc-shaped piece 12 to adjust the distance between the first arc-shaped piece 11 and the second arc-shaped piece 12, thereby controlling the size of the spraying channel, so that the cleaning liquid is sprayed through the liquid inlet channel 21 and the spraying channel for cleaning, thereby realizing the control of the flow rate of the spraying channel.

[0050] In the above embodiment, by arranging the base 2, the arc-shaped elastic piece 1 and the surrounding plate 3 arranged around the base 2, and fixedly arranging the first arc-shaped piece 11 and the second arc-shaped piece 12 included in the arc-shaped elastic piece 1 on the base 2, a spraying channel is formed between the first arc-shaped piece 11 and the second arc-shaped piece 12; wherein, a convex structure is arranged on the inner side wall of the surrounding plate 3, the surrounding plate 3 passes through the arc-shaped elastic piece 1 and is rotatably arranged on the base 2, and a liquid inlet channel 21 communicating with the spraying channel is arranged at the bottom of the base 2, so that cleaning liquid is input from the liquid inlet channel 21, and when the base 2 or the surrounding plate 3 is rotated, the convex structure can extrude the first arc-shaped piece 11 or extrude the second arc-shaped piece 12 to adjust the size of the spraying channel, thereby realizing the adjustment of the flow rate of the spraying channel. In addition, due to the arrangement of the first arc-shaped piece 11 and the second arc-shaped piece 12, the "nozzle" formed by the first arc-shaped piece 11 and the second arc-shaped piece 12 is no longer in a straight line shape, so as to increase the effective area of the spraying channel for cleaning the insulator, thereby improving the cleaning efficiency of the insulator.

[0051] In one embodiment, the convex surfaces of the first arc-shaped piece 11 and the second arc-shaped piece 12 can be arranged in the same direction. Exemplarily, such as Figure 2 、 Figures 4 - 10As shown, the convex surface of the first arc-shaped piece 11 faces the inner wall of the enclosing plate 3, the convex surface of the second arc-shaped piece 12 faces the concave surface of the first arc-shaped piece 11, and the concave surface of the second arc-shaped piece 12 faces the inner wall of the enclosing plate 3. It can be understood that the concave surface of the first arc-shaped piece 11 and the convex surface of the second arc-shaped piece 12 form a spray channel. When viewed from the top of the cleaning device, the cross-section of this spray channel is arc-shaped; or, the concave surfaces of the first arc-shaped piece 11 and the second arc-shaped piece 12 can be arranged in the same direction, that is, the convex surface of the first arc-shaped piece 11 and the concave surface of the second arc-shaped piece 12 form a spray channel. This is not limited here. To avoid redundancy, it will not be elaborated here; in one state, as Figure 7 shown, neither the first arc-shaped piece 11 nor the second arc-shaped piece 12 is squeezed. At this time, the spray channel formed by the convex surface of the first arc-shaped piece 11 and the concave surface of the second arc-shaped piece 12 is an arc-shaped channel in the natural state (the specific radian can be determined by the radians of the first arc-shaped piece 11 and the second arc-shaped piece 12); in another state, as Figure 8 shown, when the first arc-shaped piece 11 and / or the second arc-shaped piece 12 is squeezed, the spray channel at this time is an arc-shaped channel in the squeezed state. It can be understood that by rotating and adjusting the relative positions of the base 2 and the enclosing plate 3, the convex structure on the inner wall of the enclosing plate 3 is used to squeeze the first arc-shaped piece 11 or the second arc-shaped piece 12 to increase the spray pressure of the spray channel in the squeezed state.

[0052] In the above embodiment, by arranging the convex surfaces of the first arc-shaped piece 11 and the second arc-shaped piece 12 in the same direction, specifically, the convex surface of the first arc-shaped piece 11 faces the inner wall of the enclosing plate 3, and the convex surface of the second arc-shaped piece 12 faces the concave surface of the first arc-shaped piece 11, so that the spray channel formed by the concave surface of the first arc-shaped piece 11 and the convex surface of the second arc-shaped piece 12 is arc-shaped, so as to increase the spray angle through the arc-shaped spray channel, thereby improving the cleaning efficiency of the insulator. And it can realize rotating the base 2 and / or the enclosing plate 3 to adjust the spray pressure of the arc-shaped spray channel to achieve spray flow control and improve the flexibility and applicability of the cleaning device.

[0053] In one embodiment, the cleaning device further includes a support member fixed to the first arc-shaped piece 11 and / or the second arc-shaped piece 12, so that when the base 2 is rotated to a preset position, the convex structure is used to squeeze the corresponding arc-shaped piece through the support member. Specifically, as Figure 9As shown, the support member may include a first support member 41 and a second support member 42. The first support member 41 is vertically and fixedly disposed on the first arc-shaped piece 11, and the second support member 42 is vertically and fixedly disposed on the second arc-shaped piece 12. Specifically, the support member may be fixedly disposed on the corresponding arc-shaped piece by means of pasting or setting connecting members, etc. Specifically, there is no limitation, and it can be selected according to the actual scenario. That is, two support members are correspondingly provided on the arc-shaped elastic piece 1. Specifically, the first support member 41 and the second support member 42 may be set as Figure 9 the cylinder shown, so that as the base 2 or the surrounding plate 3 rotates, the convex structure can correspondingly compress or release the cylinder, and compress and release the arc-shaped piece. In specific applications, when the base 2 or the surrounding plate 3 is rotated to a preset position, the first protrusion 30a or the second protrusion 30b squeezes the first arc-shaped piece 11 through the first support member 41, and the first protrusion 30a or the second protrusion 30b squeezes the second arc-shaped piece 12 through the second support member 42 to dynamically adjust the flow rate of the injection channel.

[0054] In the above embodiment, by correspondingly providing the first support member 41 and the second support member 42 on the first arc-shaped piece 11 and the second arc-shaped piece 12, the convex structure in the surrounding plate 3 can squeeze the first arc-shaped piece 11 and / or the second arc-shaped piece 12 through the corresponding support members to adjust the injection channel, thereby reducing the thickness of the arc-shaped elastic piece 1 and reducing the manufacturing cost of the cleaning device.

[0055] In one embodiment, as Figures 4 - 8 shown, the convex structure includes a first protrusion 30a and a second protrusion 30b. The first protrusion 30a and the second protrusion 30b are correspondingly provided with the first arc-shaped piece 11 and the second arc-shaped piece 12 respectively. That is, two convex structures may be correspondingly provided on the inner side wall of the surrounding plate 3, and the positions of the two convex structures are correspondingly set with the arc-shaped piece. Specifically, as Figure 4 and Figure 5 shown, the side of the first protrusion 30a that is squeezed by the support member is an inwardly concave arc surface, and the side of the second protrusion 30b that is squeezed by the support member is an inwardly concave arc surface.

[0056] In the above embodiments, by providing the first protrusion 30a corresponding to the first arc-shaped piece 11 and the second protrusion 30b corresponding to the second arc-shaped piece 12, it is possible to squeeze the first arc-shaped piece 11 or the second arc-shaped piece 12 through the first protrusion 30a, and squeeze the first arc-shaped piece 11 or the second arc-shaped piece 12 through the second protrusion 30b, so as to simultaneously squeeze the first arc-shaped piece 11 and the second arc-shaped piece 12, thereby improving the efficiency of adjusting the injection channel; in addition, by setting the sides of the first protrusion 30a and the second protrusion 30b that are squeezed against the support member as concave arc surfaces, the thickness of the protrusion structure can be reduced as a whole, so as to not only reduce the weight of the cleaning device, making the cleaning device more portable, but also reduce the manufacturing cost.

[0057] In one embodiment, the protrusion structure can also be provided in the following manner, such as Figure 4 As shown, when viewed from the top direction of the cleaning device, along the clockwise direction, the distance between the side of the first protrusion 30a that is squeezed against the corresponding support member and the central axis C of the surrounding plate gradually decreases, and the distance between the side of the second protrusion 30b that is squeezed against the corresponding support member and the central axis C of the surrounding plate gradually decreases. It can be understood that when moving in the counterclockwise direction, the distance between the side of the first protrusion 30a that is squeezed against the corresponding support member and the central axis C of the surrounding plate gradually increases, and the distance between the side of the second protrusion 30b that is squeezed against the corresponding support member and the central axis C of the surrounding plate gradually increases. Exemplarily, when the cleaning device is sectioned horizontally, the distance D1 between the starting point of the first protrusion 30a and the injection center can be set to be the largest. Along the clockwise direction, the distances D2, D3... Dn between the remaining points and the injection center gradually decrease. Similarly, the distance between the starting point of the second protrusion 30b and the injection center can be set to be the largest, and along the clockwise direction, the distances between the remaining points and the injection center gradually decrease. To avoid redundancy, the description will not be elaborated here.

[0058] In the above embodiments, by setting the distance between the side of the protrusion structure that is squeezed against the corresponding support member and the central axis C of the surrounding plate to gradually decrease, when actually squeezing the first arc-shaped piece 11 or the second arc-shaped piece 12 in a predetermined direction (clockwise or counterclockwise), it is possible to gradually increase or decrease the flow rate of the injection channel, so as to improve the spraying stability of the cleaning device.

[0059] Or, in another embodiment, such as Figure 5As shown, when viewed from the top-down direction of the cleaning device, in the clockwise direction, the distance between the side of the first protrusion 30a that is pressed against the corresponding support member and the central axis C of the surrounding plate first gradually decreases and then gradually increases. The distance between the side of the second protrusion 30b that is pressed against the corresponding support member and the central axis C of the surrounding plate first gradually decreases and then gradually increases. It can be understood that when in the counterclockwise direction, the distance between the side of the first protrusion 30a that is pressed against the corresponding support member and the central axis C of the surrounding plate first gradually decreases and then gradually increases, and the distance between the side of the second protrusion 30b that is pressed against the corresponding support member and the central axis C of the surrounding plate first gradually decreases and then gradually increases. Specifically, reference can be made to the process of the above-mentioned Figure 4 embodiment. To avoid redundancy, it will not be elaborated here.

[0060] In the above embodiment, by setting the distance between the side of the protrusion structure that is pressed against the corresponding support member and the central axis C of the surrounding plate to first gradually decrease and then gradually increase, it is possible to adjust the flow rate of the injection channel when rotating the base 2 (or the surrounding plate 3) clockwise or counterclockwise, so as to improve the stability of the injection application of the cleaning device.

[0061] In addition, for the sake of easy understanding, the above limitation on the protrusion structure can also be understood as the change in the thickness of the protrusion structure. Specifically, as Figures 4 - 8 shown, the inner wall of the surrounding plate 3 can be set to be cylindrical. When the cleaning device is horizontally sectioned, it can be understood that the thickness of the protrusion structure gradually changes clockwise or counterclockwise. For example, it gradually becomes smaller in the above embodiment, or first gradually becomes smaller and then gradually becomes larger. To avoid redundancy, it will not be elaborated here.

[0062] It should be noted that the above embodiments in combination with the drawings are only for examples and are not limiting. Exemplarily, in another embodiment, the protrusion structure can also be set in the following manner, as Figure 6 shown, the side of the first protrusion 30a that is pressed against the support member can be set as an inwardly convex arc surface, and the side of the second protrusion 30b that is pressed against the support member can be an inwardly convex arc surface. Then, through the protrusion structure of this inwardly convex arc surface, it is also possible to respectively press the arc-shaped elastic piece 1 to realize the dynamic adjustment of the injection channel.

[0063] In one embodiment, as Figure 4 or Figure 5 shown, the outer shapes of the first protrusion 30a and the second protrusion 30b are the same, and the outer shapes of the first arc-shaped piece 11 and the second arc-shaped piece 12 are the same. Among them: The first protrusion 30a and the second protrusion 30b are centrally symmetrically arranged on the inner side wall of the surrounding plate 3. That is, when the first protrusion 30a rotates a certain angle around the center, it can coincide with the second protrusion 30b, or when the second protrusion 30b rotates a certain angle around the center, it can coincide with the first protrusion 30a.

[0064] In the above embodiment, by setting the shapes of the first protrusion 30a and the second protrusion 30b to be the same, and the shapes of the first arc-shaped piece 11 and the second arc-shaped piece 12 to be the same, and the first protrusion 30a and the second protrusion 30b are arranged on the inner wall of the enclosure 3 in a centrally symmetrical manner, the distribution of the cleaning device in the space can be made more uniform and reasonable, so as to improve the symmetry of the cleaning device, thereby making the movable space of the support member and the arc-shaped piece after assembly smoother, and improving the smoothness of the protrusion structure squeezing the support member, thereby improving the user experience of the cleaning device.

[0065] In addition, based on the fact that the shapes of the first protrusion 30a and the second protrusion 30b are set to be the same, the above-mentioned first arc-shaped piece 11, second arc-shaped piece 12, first support member 41 and second support member 42 can all be set to be the same, so that each matching part in the cleaning device is symmetrical and uniform, and the layout is more reasonable.

[0066] In one embodiment, Figure 3 As shown, the inner wall is cylindrical, the base 2 is cylindrical, and the liquid inlet channel 21 is arranged at the center of the base 2. In this embodiment, by arranging the liquid inlet channel 21 at the center of the base 2, the space of the cleaning device can be fully utilized to improve the spraying efficiency.

[0067] In one embodiment, Figure 2 , Figure 3 , Figure 9 and Figure 10 As shown, the first arc-shaped piece 11 and the second arc-shaped piece 12 are formed as one piece, which can be specifically realized by a process such as stamping. An opening 131 is provided on the connecting end 13 between the first arc-shaped piece 11 and the second arc-shaped piece 12; the base 2 is also provided with a nozzle 22 which is connected to the injection channel and extends into the opening 131 of the connecting end 13, and the nozzle 22 is located in the injection channel.

[0068] In the above embodiment, by forming the first arc-shaped piece 11 and the second arc-shaped piece 12 as one piece and providing an opening 131 on the connecting end 13, it is convenient to fix the arc-shaped spring piece 1 on the base 2 and to install the pipeline, thereby improving practicality.

[0069] In one embodiment, the arc-shaped spring piece 1 and the support member can be formed as one piece, which can be achieved specifically through welding technology, etc. In this embodiment, by forming the arc-shaped spring piece 1 and the support member as one piece, the fit between the arc-shaped spring piece 1 and the support member can be made tighter, and the assembly process can be reduced, thereby improving the durability of the cleaning device.

[0070] In one embodiment, the enclosure 3 and the raised structure can be formed as one piece, which can be achieved by injection molding or infusion. In this embodiment, by forming the enclosure 3 and the raised structure as one piece, the fit between the enclosure 3 and the raised structure can be made tighter, and the assembly process can be reduced, thereby improving the durability and stability of the cleaning device.

[0071] In one embodiment, the liquid inlet channel 21 is also provided with a threaded structure (not shown in the figure) for connecting the injection device. In this embodiment, by providing a threaded structure on the liquid inlet channel 21, it is convenient to connect the external injection device, thereby improving the flexibility of the cleaning device application.

[0072] Example 2

[0073] The second aspect of the present invention provides a cleaning system. In one embodiment, the cleaning system includes the cleaning device in any one of the above-mentioned embodiments 1. The cleaning system in this embodiment, through the cleaning device in the above-mentioned embodiment, can realize an arc-shaped spray channel through the cleaning device, thereby increasing the spray area on the insulator, so as to improve the cleaning efficiency of the cleaning system.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
