[0040] As described in the background technology, in the substation, the wall of the bushing with a porcelain skirt needs to be cleaned frequently to ensure the stability of its insulation performance and protect the electrical equipment installed in the bushing. In the related technology, the cleaning methods of the bushing include pressure water washing and manual wiping. Among them, pressure water washing is to use a high-pressure water gun to spray water to clean the outer periphery of the bushing, and manual wiping is performed by a worker wearing a safety belt standing on the bushing base and using a rag to wipe the surface of different sides of the outer periphery of the bushing. The pressure water washing method has the problem of large water consumption, easy to cause waste of resources, and easy damage of the bushing and internal equipment by high-pressure hydraulic equipment; and the efficiency of manual wiping of the bushing is low.

[0041] After research by the applicant, it was found that the reasons for the above problems are: the pressure water washing method in the relevant technology consumes a large amount of water and wastes a lot of water resources. Moreover, the ground in the environment where the substation is located has a lot of broken sand and gravel. Under this condition, the water tank used for water washing is inconvenient to carry, resulting in more manpower for transportation. In addition, when spraying water with a high-pressure water gun to clean the casing, there is a problem of water entering the junction box and terminal box in the casing, causing a short circuit in the wiring. At the same time, due to the high hydraulic pressure, the impact of high-pressure water on the porcelain skirt of the casing is also easy to cause damage to the porcelain skirt, and when the salinity of the water body is high, it will affect the cleaning effect; and the manual wiping method of the casing consumes a lot of workers' physical strength, and the casing with a higher voltage level and longer size requires multiple manpower. Workers need to climb the casing for cleaning, and the operation safety is low and the cleaning efficiency of the casing is low. Not only that, when the workers move around the casing, the safety belts they are tied with often break the porcelain skirt of the casing, causing damage to the equipment.

[0042] In view of the above technical problems, an embodiment of the utility model provides a pipe cleaning device, which is arranged on the outer wall of the pipe, and stably supports the wiping member through two arc-shaped shells surrounding the outer circumference of the pipe, and the force-applying member connected to the wiping member is arranged on the outer wall of the pipe. The force-applying member is rotated by the circumferential force along the arc-shaped shell to drive the wiping member to wipe the pipe, or the force-applying member is driven by the radial force along the arc-shaped shell to move in the avoidance space. Compared with the related technology of cleaning pipes with water pressure and directly wiping pipes with human hand-held wiping members, the rotating wiping member circumferentially wipes the outer wall of the pipe, which not only improves the cleaning effect of a single porcelain skirt on the outer wall of the pipe, but also facilitates the cleaning device to move the wiping position, thereby improving the overall wiping efficiency of the outer wall of the pipe.

[0043] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0044] In order to make the above-mentioned purposes, features and advantages of the embodiments of the utility model more obvious and easy to understand, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0045] Combination Figure 1 The structural schematic diagram of the pipe cleaning device provided by the embodiment of the utility model, the embodiment of the utility model provides a pipe cleaning device, which is arranged on the outer wall of the pipe, and the pipe cleaning device comprises: a support member 100, comprising at least two arc-shaped shells 120, the two arc-shaped shells 120 are movably connected, and are used to surround and be arranged on the outer periphery of the pipe, and an escape space 110 is defined between the arc-shaped shell 120 and the side wall of the pipe, and the arc-shaped shell is provided with an opening; at least two wiping members 200, which are respectively movably connected to the shell wall of the arc-shaped shell 120, and the wiping members 20 ... 0 The side away from the arc-shaped shell 120 is attached to the outer wall of the pipe; the force-applying member 300 is passed through the arc-shaped shell 120 through the opening and is fixedly connected to the wiping member 200. The force-applying member 300 is configured to rotate along the circumferential force of the arc-shaped shell 120 to drive the wiping member 200 to wipe the pipe. The force-applying member 300 is configured to rotate along the circumferential force of the arc-shaped shell 120 to drive the wiping member 200 to wipe the pipe, and the force-applying member 300 can be driven by the radial force of the arc-shaped shell 120 to drive the wiping member 200 to move in the avoidance space 110.

[0046] In this way, the wiping member 200 is stably supported by two arc-shaped shells 120 surrounding the outer circumference of the pipe, and the force-applying member 300 connected to the wiping member 200 is arranged on the outer wall of the pipe. The force-applying member 300 is rotated by the circumferential force along the arc-shaped shell 120 to drive the wiping member 200 to wipe the pipe, or the force-applying member 300 is driven by the radial force along the arc-shaped shell 120 to move the wiping member 200 in the avoidance space 110. Compared with the water pressure cleaning of the pipe and the manual hand-held wiping member 200 directly wiping the pipe in the related art, the rotating wiping member 200 circumferentially wipes the outer wall of the pipe, which not only improves the cleaning effect of the single porcelain skirt of the outer wall of the pipe, but also facilitates the cleaning device to move the wiping position, thereby improving the overall wiping efficiency of the outer wall of the pipe.

[0047] In a possible embodiment, there are at least two force-applying members, and the pipe cleaning device also includes at least two elastic members 400, the two ends of the elastic member 400 are respectively connected to the connecting ends of the wiping member 200 and the force-applying member, and between the inner wall of the arc shell 120, and the elastic force direction of the elastic member 400 points to the wiping member 200, so that the force-applying member presses the wiping member 200 against the outer wall of the pipe under the elastic force of the elastic member 400. Exemplarily, the elastic member 400 is a spring. When the cleaning device is used to wipe the outer wall of the pipe, the spring is compressed and its elastic force points to the wiping member 200, so as to improve the fit between the wiping member 200 and the porcelain skirt of the sleeve.

[0048] In some embodiments, the force-applying member 300 includes a pull rod 310, a first end of the pull rod 310 is fixedly connected to the wiping member 200, the arc-shaped shell 120 is provided with an opening, and the second end of the pull rod 310 extends out of the arc-shaped shell 120 along the opening. The pull rod 310 is subjected to force to drive the wiping member 200 to move in a direction close to the arc-shaped shell 120 in the avoidance space 110.

[0049] As a possible implementation, the elastic member 400 is a spring, which is sleeved on the outer periphery of the second end of the pull rod 310 , the first end of the spring is connected to the inner wall of the arc shell 120 , and the second end of the spring is connected to the wiper 200 .

[0050] On the basis of the above embodiment, it can be improved that the force-applying member 300 also includes a sheath 320, which is sleeved on the outer periphery of the pull rod 310. The sheath 320 includes a hand-holding portion and an annular protective portion. The hand-holding portion is axially sleeved on the outer periphery of the pull rod 310, and the annular protective portion extends circumferentially along the hand-holding portion and is located on the side of the hand-holding portion close to the arc shell 120. The material of the sheath 320 is a polymer material, for example, a rubber material. In this way, the sheath 320 serves as a handle of the force-applying member 300 to facilitate personnel to operate the force-applying member 300, and the annular protective portion is arranged to provide support along the radial direction of the arc shell 120 when personnel apply force to the hand-holding portion.

[0051] In other possible embodiments, the two arcuate shells 120 are hingedly connected, and the first ends of the two arcuate shells 120 are connected by snaps 150. Exemplarily, the arcuate shells 120 are semicircular shells, also called semicircular positioning rings, and the two semicircular shells are movably connected.

[0052] Based on the above embodiment, it can be improved that, in combination with Figure 2 A first end of one of the two arcuate shells 120 is provided with a latching position 130, and a snap ring 140 is movably connected to the latching position 130. A snap buckle 150 is provided at the first end of the other arcuate shell 120, and the snap buckle 150 is engaged with the snap ring 140 to connect the first end snap buckles 150 of the two arcuate shells 120. In other words, the arcuate shell 120 acts as an external positioning ring, and the two arcuate shells 120 connected by the snap buckle 150 realize the flexible opening and closing of the arcuate shell 120, which not only plays the role of circumferential positioning support for the overall cleaning device, but also facilitates the flexible installation or disassembly of the internal components of the arcuate shell 120.

[0053] Specifically, the working process of the cleaning device in this embodiment is explained. The buckle 150 is opened, and the opening between the two arc-shaped shells 120 is expanded by pulling the force-applying member 300. After the cleaning device is mounted on the outer periphery of the sleeve to be cleaned, the buckle 150 is buckled with the retaining ring 140. The sleeve to be cleaned has multiple flanges spaced apart along the axial direction, also called porcelain skirts. The porcelain skirt of the sleeve can be wiped and cleaned by rotating the force-applying member 300 once. Furthermore, by applying a force radially away from the arc-shaped shell 120 to the force-applying member 300, that is, pulling the force-applying member 300, the distance between the wiping members 200 located on both sides of the sleeve can be expanded, leaving a radial avoidance space 110 for the pipe cleaning device to move axially along the sleeve to be cleaned, and then the cleaning device can be lifted or lowered to continue wiping the porcelain skirts of adjacent sleeves, so that the cleaning is efficient and labor-saving.

[0054] Moreover, this structural design can ensure that the pipe cleaning device can wipe and clean sleeves with different outer diameters, and the application range of the workpiece service is relatively wide.

[0055] In more possible embodiments, Figure 3 As shown, the second ends of the two arc-shaped shells 120 are respectively provided with connecting plates 160, and the second end is the end away from the first end. The two connecting plates 160 are correspondingly arranged and connected by a rotating shaft to form the first ends of the two arc-shaped shells 120 hingedly connected. Specifically, the arc-shaped shells 120 and the connecting plates 160 are respectively provided with mounting holes, and the connecting plates 160 are fixedly connected to the arc-shaped shells 120 by bolts passing through the mounting holes. In this way, a more flexible opening and closing structure is formed between the two arc-shaped shells 120 with a hinged design, which is convenient for installation and removal on the pipe fittings to be cleaned.

[0056] In other possible implementations, reference Figure 4 The wiping member 200 includes a base 210 and a wiping block 220. The base 210 is movably connected to the arc-shaped shell 120 through a force-applying member 300. The side of the base 210 facing away from the arc-shaped shell 120 is fixed to the wiping block 220.

[0057] The pipe fitting has a plurality of annular protrusions arranged at intervals along the axial direction of its own pipe body, and the wiping block 220 is adapted to the shape of the groove formed by the annular protrusions on the side wall of the pipe fitting. The wiping block 220 has two wiping surfaces 221 opposite to each other in the vertical direction. When the wiping block 220 is located between two adjacent annular protrusions, the wiping surface 221 is tightly fitted to the two opposite surfaces of the two adjacent annular protrusions, that is, the wiping block 220 has a connecting side wall connected to the base 210 and a wedge-shaped portion extending along the connecting side wall toward one side of the pipe fitting to be cleaned, and the upper and lower side surfaces of the wedge-shaped portion along its own extension direction are arc-shaped concave surfaces to better adapt to the shape of the groove between the porcelain skirts of the pipe fittings, so that the wiping surface 221 of the wiping block 220 fits with the outer surface of the porcelain skirt of the pipe fitting, thereby improving the cleaning efficiency.

[0058] In some embodiments, the wiping block 220 is a flexible cotton body, and the wiping block 220 is bonded to the base 210. Exemplarily, the flexible cotton body is made of pure cotton, synthetic fiber, or microfiber to meet different cleaning requirements including water absorption, adsorption, anti-static and antibacterial.

[0059] The embodiments of the present application have the following beneficial effects:

[0060] The annular structure formed by the two movably connected arcuate shells 120 serves as an outer support ring for the wiping member 200 arranged therein. At the same time, the two arcuate shells 120 are hinged at one end and connected by a buckle 150 at the other end, which is convenient for opening and closing. When the cleaning device needs to be installed on the pipe to be cleaned, the buckle 150 on the arcuate shell 120 is opened, and radial tension is applied to the force-applying member 300 to expand the gap between the arcuate shell 120 and the two wiping members 200 arranged on the side of the pipe, so that the cleaning device is sleeved on the outer periphery of the porcelain skirt of the pipe and locked by the buckle 150. An elastic member 400 with elastic force pointing to the wiping member 200 is arranged between the arc shell 120 and the wiping member 200, which can enhance the fit between the wiping member 200 and the pipe to be cleaned. In this way, the circumferential wiping of the porcelain skirt of the pipe can be achieved by rotating the force-applying member 300. In addition, the staff can pull the force-applying member 300 with both hands to make the wiping member 200 move radially in the avoidance space 110 between itself and the inner wall of the arc shell 120, so that the wiping member 200 is separated from the pipe wall of the pipe to be cleaned, and then the position of the cleaning device can be changed to the porcelain skirt adjacent to the pipe for further wiping and cleaning work.
