[0026] Upon request, specific embodiments of the present invention will be disclosed herein. However, it should be understood that the embodiments disclosed herein are merely typical examples of the present invention, which may be embodied in various forms. Therefore, the specific details disclosed herein are not to be considered restrictive, but merely as a basis for the claims and as a representative basis for teaching those skilled in the art to apply the present invention in various ways in any appropriate manner in practice, including using the various features disclosed herein and in combination with features that may not be explicitly disclosed herein.

[0027] Embodiment 1:

[0028] like Figure 1-Figure 4 As shown, the auxiliary umbrella cover 100 of the present embodiment is covered on the outside of the insulator 10, and the insulator 10 includes at least one umbrella skirt 20. A receiving cavity 113 is formed in the auxiliary umbrella cover 100, and the receiving cavity 113 at least receives the single umbrella skirt 20. The auxiliary umbrella cover 100 includes an umbrella cover body 110, a first connecting portion 120 and a second connecting portion 130. The first connecting portion 120 and the second connecting portion 130 are respectively arranged at two ends of the umbrella cover body 110. The first connecting portion 120 can be inserted into the second connecting portion 130 to close the auxiliary umbrella cover 100 in the circumferential direction, so that the umbrella skirt 20 is received in the receiving cavity 113. The thickness of the overlapping area of ​​the first connecting portion 120 and the second connecting portion 130 is consistent with the thickness of the umbrella cover body 110, so that the outer surface of the auxiliary umbrella cover 100 has a smooth transition. The auxiliary umbrella cover 100 has a first connection portion 120 that can be inserted into the second connection portion 130, and the length of the overlapping area between the first connection portion 120 and the second connection portion 130 can be adjusted according to the diameter of the umbrella skirt 20 of the insulator 10, thereby achieving the adjustment of the inner and outer diameters of the auxiliary umbrella cover 100 after installation within a certain range.

[0029] In this embodiment, after the first connection part 120 is inserted into the second connection part 130, the auxiliary umbrella cover 100 is connected as a whole after being sealed by an adhesive. In other embodiments, a sealing tape or a sealing strip may also be used for connection.

[0030] In other embodiments, a locking structure is provided at corresponding positions of the first connection part and the second connection part. The design of the locking structure can effectively prevent the first connection part or the second connection part from warping, and can also prevent the second connection part from falling off due to gravity.

[0031] In this embodiment, the first connection portion 120 extends from one end of the umbrella cover body 110 along the circumferential direction of the umbrella cover body 110, the inner surface 122 of the first connection portion 120 is flush with the inner surface 112 of the umbrella cover body 110, and the outer surface 121 of the first connection portion 120 is lower than the outer surface 111 of the umbrella cover body, so that a first recess is formed between the outer surface 121 of the first connection portion 120 and the outer surface 111 of the umbrella cover body. The second connection portion 130 extends from the other end of the umbrella cover body 110 along the circumferential direction of the umbrella cover body 110, the outer surface 131 of the second connection portion 130 is flush with the outer surface 111 of the umbrella cover body 110, and the inner surface 132 of the second connection portion 130 is lower than the inner surface 112 of the umbrella cover body 110, so that a second recess is formed between the inner surface 132 of the second connection portion 130 and the inner surface 112 of the umbrella cover body 110. When the first connection part 120 is inserted into the second connection part 130, the first connection part 120 is accommodated in the second recess, and the second connection part 130 is accommodated in the first recess. The inner surface and the outer surface of the first connection part 120 and the second connection part 130 are both flat, which is convenient for the fit between the two and can ensure a smooth transition of the outer surface of the auxiliary umbrella cover 100. If there are defects on the inner surface, they can be filled with adhesives or other materials.

[0032] When the first connection part 120 is inserted into the second connection part 130, the length of the overlapping area of ​​the first connection part 120 and the second connection part 130 can be adjusted to adapt to the diameter of the shed 20 of the insulator 10. Specifically, when the size of the auxiliary umbrella cover 100 just matches the size of the shed 20 of the insulator 10, the first connection part 120 and the second connection part 130 are completely overlapped when the auxiliary umbrella cover 100 is closed in the circumferential direction. When the size of the auxiliary umbrella cover 100 is larger than the size of the shed 20 of the insulator 10, the length of the first connection part 120 and the second connection part 130 can be cut to make the size of the auxiliary umbrella cover 100 match the size of the shed 20 of the insulator 10. When the size of the auxiliary umbrella cover 100 is smaller than the size of the shed 20 of the insulator 10, the circumferential size of the auxiliary umbrella cover 100 is extended by only partially overlapping the first connecting portion 120 and the second connecting portion 130. At this time, there is still a partial cavity area in the second recess of the second connecting portion 130, which can be filled with other substances such as adhesives to make the inner surface of the auxiliary umbrella cover 100 fit closely with the shed 20 of the insulator 10; there is also a partial cavity area in the first recess of the first connecting portion 120, which can be filled with other substances such as adhesives or not.

[0033] In other embodiments, the inner surface and outer surface of each of the first connecting part and the second connecting part can be roughened to a certain extent, such as increasing the surface roughness or adding a concave-convex design to the surface, as long as it does not hinder the fit between the first connecting part and the second connecting part. In this case, the first connecting part and the second connecting part can be fixedly connected using an adhesive or a sealing tape.

[0034] In other embodiments, the outer surface of the first connection part is provided with a strip groove along the circumference of the auxiliary umbrella cover, and the inner surface of the second connection part is provided with a strip protrusion corresponding to the above groove along the circumference of the auxiliary umbrella cover, and the strip protrusion can slide in the strip groove to achieve the purpose of adjusting the length of the overlapping area between the first connection part and the second connection part. It can be understood that in other embodiments, the outer surface of the first connection part is provided with a strip protrusion along the circumference of the auxiliary umbrella cover, and the inner surface of the second connection part is provided with a strip groove corresponding to the above groove along the circumference of the auxiliary umbrella cover. In the above situation, the first connection part and the second connection part are connected by an adhesive or tape to assist, and the connection strength is more stable than the planar bonding structure.

[0035] In this embodiment, the circumferential angle of the umbrella cover body 110 is less than 360°, and the circumferential angle of the auxiliary umbrella cover 100 is equal to 360°. It can be understood that the area after the first connecting portion 120 and the second connecting portion 130 are overlapped plus the umbrella cover body 110 is just combined into a circle, that is, at this time, the circumferential angle of the auxiliary umbrella cover 100 is exactly equal to 360°, and the auxiliary umbrella cover 100 can be set on the umbrella skirt 20 of the insulator 10 whose size just matches.

[0036] In other embodiments, the diameters of several sheds on the insulator may be unequal. In order to simultaneously meet the needs of insulator sheds of different diameters, the circumferential angle design of the auxiliary shed may be divided into the following different situations.

[0037] In some embodiments, the circumferential angle of the umbrella cover body is less than 360°, and the circumferential angle of the auxiliary umbrella cover is greater than 360°. In this case, the circumferential angle of the auxiliary umbrella cover formed by the overlapping area of ​​the first connecting part and the second connecting part plus the umbrella cover body is greater than 360°. The auxiliary umbrella cover can be mounted on the umbrella skirt of an insulator with a slightly larger size.

[0038] In some embodiments, the circumferential angle of the umbrella cover body is equal to 360°, and the circumferential angle of the auxiliary umbrella cover is greater than 360°. In this case, the circumferential angle of the auxiliary umbrella cover formed by the overlapping area of ​​the first connecting part and the second connecting part plus the umbrella cover body is greater than 360°. The auxiliary umbrella cover can be mounted on the umbrella skirt of an insulator with a slightly larger size.

[0039] In some embodiments, the circumferential angle of the umbrella cover body is less than 360°, and the circumferential angle of the auxiliary umbrella cover is less than 360°. In this case, the circumferential angle of the auxiliary umbrella cover formed by the overlapping area of ​​the first connecting part and the second connecting part plus the umbrella cover body is less than 360°. The auxiliary umbrella cover can be mounted on the umbrella skirt of an insulator with a slightly smaller size.

[0040] In this embodiment, since the size of the umbrella cover body 110 is fixed, but the size of the overlapping area of ​​the first connecting portion 120 and the second connecting portion 130 can be adjusted according to the actual installation situation, the circumferential angle of the auxiliary umbrella cover 100 may not be fixed, that is, the size of the auxiliary umbrella cover 100 can be adjusted within a certain range, which can ensure that when the outer diameter of the shed 20 of the insulator 10 changes within a certain range, the auxiliary umbrella cover 100 can adapt to the shed 20 of the insulator 10 of different sizes.

[0041] In this embodiment, the umbrella cover body 110 is divided into an upper umbrella body 114 and a lower umbrella body 115 at the umbrella tip of the umbrella skirt 20 received by the receiving cavity 113. In the axial direction of the auxiliary umbrella cover 100, the upper umbrella body 114 and the lower umbrella body 115 extend the upper sheath 150 and the lower sheath 160 respectively toward the outside of the umbrella cover body 110 along the edge of the receiving cavity 113. The structures of the upper sheath 150 and the lower sheath 160 are both annular, and are respectively sleeved on the outer circumference of the insulating column between the umbrella skirts 20 of the insulator 10. The arrangement of the upper sheath 150 and the lower sheath 160 can cover part of the area between the umbrella skirts 20 of the insulator 10, which is conducive to lengthening the sealing path of the auxiliary umbrella cover 100, so that it is not easy for moisture to penetrate into the interior of the auxiliary umbrella cover 100, and the electrical performance of the auxiliary umbrella cover 100 will not be affected.

[0042] Embodiment 2:

[0043] like Figure 5-Figure 6 As shown, this embodiment provides an auxiliary umbrella cover 200, which is different from the auxiliary umbrella cover 100 in the structure of the umbrella cover body 210, and the other structures are the same as the auxiliary umbrella cover 100, which will not be repeated here.

[0044] In this embodiment, the umbrella cover body 210 includes a first body 211 and a second body 212, and the first body 211 and the second body 212 are assembled into the umbrella cover body 210. The umbrella cover body 210 is divided into two parts, which can simplify the manufacturing mold and reduce the production cost; and during the installation process, especially when installed on the insulator shed with a large diameter, the installation of the split umbrella cover is more flexible, the construction is convenient, and the risk of high-altitude operation can be reduced.

[0045] In this embodiment, the first body 211 and the second body 212 have the same structure, and the first and second connecting parts 220 and 230 are respectively provided at both ends of the first and second bodies 211 and 212. The first and second bodies 211 and 212 have the same structure, and the same manufacturing mold can be used, which can reduce production costs and manufacturing difficulty.

[0046] It can be understood that in this embodiment, the first connecting portion 220 and the second connecting portion 230 are respectively provided at both ends of the first body 211, and the first connecting portion 220 and the second connecting portion 230 are also respectively provided at both ends of the second body 212, and the circumferential angles of the first body 211 and the second body 212 are equal, then the first body 211 and the second body 212 have the same structure. The first connecting portion 220 at one end of the first body 211 and the second connecting portion 230 at one end of the second body 212 are connected to form the umbrella cover body 210, and at this time, the first connecting portion 220 and the second connecting portion 230 are still respectively provided at both ends of the umbrella cover body 210. The second connecting portion 230 at the other end of the first body 211 and the first connecting portion 220 at the other end of the second body 212 are the second connecting portion 230 and the first connecting portion 220 at both ends of the umbrella cover body 210.

[0047] In other embodiments, the first body and the second body may have different structures, which can be mainly divided into the following two situations.

[0048] In the first case, in some embodiments, the circumferential angles of the first body and the second body are equal, and the first connecting parts are provided at both ends of the first body, and the second connecting parts are provided at both ends of the second body. In this case, the first body and the second body need to be prepared by splitting the mold. The first connecting part at one end of the first body and the second connecting part at one end of the second body are connected to form the umbrella cover body, and the first connecting part and the second connecting part are still provided at both ends of the umbrella cover body respectively. Alternatively, the second connecting part is provided at both ends of the first body, and the first connecting part is provided at both ends of the second body. These two situations are similar and will not be repeated.

[0049] In the second case, in other embodiments, the circumferential angles of the first body and the second body are not equal, a first connecting portion and a second connecting portion are provided at one end of the first body and one end of the second body, and the other end of the first body and the other end of the second body are spliced ​​and connected, that is, the specific connection structure and connection method of the first body and the second body are not specifically limited herein, and after the first body and the second body are spliced ​​into the umbrella cover body, the first connecting portion and the second connecting portion are respectively provided at both ends of the umbrella cover body.

[0050] The auxiliary umbrella cover 200 of this embodiment can simplify the manufacturing mold and reduce the production cost because the umbrella cover main body 210 is designed to be split. In addition, during the installation process, especially when installed on the insulator shed with a large diameter, the split umbrella cover is more flexible to install and convenient to construct, which can reduce the risk of high-altitude operations.

[0051] Embodiment three:

[0052] like Figure 7-Figure 9 As shown, this embodiment provides an auxiliary umbrella cover 300, which is different from the auxiliary umbrella cover 200 in the extension portion 340, and the other structures are the same as the auxiliary umbrella cover 200, which will not be repeated here.

[0053] In this embodiment, taking the first main body 311 as an example, the upper surface of the upper umbrella body 314 and the second connecting portion 330 extends outward from the umbrella tip of the auxiliary umbrella cover 300 to form an extension portion 340. The provision of the extension portion 340 can increase the creepage distance of the auxiliary umbrella cover 300.

[0054] In other embodiments, the extended portion may also be flush with the lower surfaces of the lower parachute body and the second connecting portion, both of which can increase the creepage distance of the auxiliary parachute cover.

[0055] Since the auxiliary umbrella cover 300 of the present embodiment is provided with the extension portion 340 , the creepage distance of the auxiliary umbrella cover 300 is increased, so that the auxiliary umbrella cover 300 has better electrical performance.

[0056] Embodiment 4:

[0057] Combination Figure 1-4 The present embodiment provides a method for installing an auxiliary umbrella cover 100, wherein the auxiliary umbrella cover 100 is covered on the outside of an insulator 10, the insulator 10 includes at least one umbrella skirt 20, and a receiving cavity 113 is formed in the auxiliary umbrella cover 100, and the receiving cavity 113 at least receives a single umbrella skirt 20, comprising the following steps:

[0058] a. Apply adhesive to the inner surface of the auxiliary umbrella cover 100;

[0059] b. The auxiliary umbrella cover 100 is correspondingly mounted on the umbrella skirt 20;

[0060] c. Insert the first connecting portion 120 into the second connecting portion 130 to close the umbrella cover body 110 in the circumferential direction.

[0061] In this embodiment, the installation method of the auxiliary umbrella cover 100 can simplify the connection method because the first connection part 120 is inserted into the second connection part 130, and at the same time, the outer surface 111 of the auxiliary umbrella cover 100 has a smooth transition.

[0062] In other embodiments, in step a, adhesive is applied to the outer surface of the insulator shed.

[0063] In other embodiments, in step a, adhesive may also be coated on the inner surface of the auxiliary shed and the outer surface of the insulator shed.

[0064] In other embodiments, if the insulator is an insulator of unequal diameter, and the diameters of the sheds on the same insulator are not equal, in step c, the length of the overlapping area of ​​the first connection part and the second connection part is adjusted according to the diameter of the shed. Since the first connection part of the auxiliary shed can be inserted into the second connection part, and the lengths of the first connection part and the second connection part can be adjusted according to the diameter of the insulator shed, that is, the length of the overlapping area of ​​the first connection part and the second connection part is adjusted, the outer diameter of the auxiliary shed can be adjusted within a certain range.

[0065] In this embodiment, in step c, the first connection part 120 and the second connection part 130 are connected by adhesive, that is, the adhesive is coated on the outer surface 121 of the first connection part 120 and / or the inner surface 132 of the second connection part 130 .

[0066] In other embodiments, the first connection part and the second connection part may also be bonded with a sealing tape. One way is to set a double-sided sealing tape on the outer surface of the first connection part or the inner surface of the second connection part. Another way is to use sealing tape to bond the gap between the first connection part and the second connection part on the outer surface and the inner surface of the auxiliary umbrella cover.

[0067] In the installation method of the auxiliary umbrella cover 100 of the present embodiment, since the first connecting portion 120 is inserted into the second connecting portion 130 , the connection method can be simplified, and at the same time, the outer surface 111 of the auxiliary umbrella cover 100 has a smooth transition.

[0068] Embodiment five:

[0069] Combination Figure 5-6 This embodiment provides a method for installing an auxiliary umbrella cover 200. The difference from the fourth embodiment is that the auxiliary umbrella cover 200 includes a first body 211 and a second body 212 with the same structure. During installation, the first body 211 and the second body 212 need to be assembled. The method specifically includes the following steps:

[0070] a. Apply adhesive to the inner surface of the first body 211 and the inner surface of the second body 212 of the auxiliary umbrella cover 200 or apply adhesive to the outer surface of the insulator umbrella skirt;

[0071] b. The first main body 211 and the second main body 212 of the auxiliary umbrella cover 200 are correspondingly mounted on the umbrella skirt;

[0072] c. Insert the first connecting portion 220 into the second connecting portion 230 to close the auxiliary umbrella cover 200 in the circumferential direction.

[0073] In this embodiment, the first body 211 and the second body 212 have the same structure. In step c, the first connection portion 220 of the first body 211 is inserted into the second connection portion 230 of the second body 212, and the first connection portion 220 of the second body 212 is inserted into the second connection portion 230 of the first body 211, so that the auxiliary umbrella cover 200 is closed in the circumferential direction.

[0074] In other embodiments, the structures of the first body and the second body are different. In step c, one end of the first body and the second body must be connected first, and then the first connecting part of the first body is inserted into the second connecting part of the second body to close the auxiliary umbrella cover in the circumferential direction.

[0075] The installation method of the auxiliary umbrella cover 200 of this embodiment can simplify the manufacturing mold and reduce the production cost because the umbrella cover main body 210 is designed to be split; and during the installation process, especially when installed on the insulator shed with a large diameter, the installation of the split umbrella cover is more flexible, which can reduce the risk of high-altitude operations.

[0076] The technical content and technical features of the present invention have been disclosed above, but it is understood that under the creative ideas of the present invention, those skilled in the art can make various changes and improvements to the above structures and materials, including combinations of technical features disclosed or claimed separately herein, and obviously including other combinations of these features. These variations and / or combinations all fall within the technical field involved in the present invention and fall within the protection scope of the claims of the present invention.
