Description

Technical Field

[0001] This invention relates to the field of overhead power transmission line maintenance equipment technology, and in particular to a cable anti-corrosion grease coating component and device. Background Technology

[0002] In highly corrosive environments characterized by high salinity, high temperature, and high humidity, such as coastal areas, Gobi Desert, and tropical rainforests, the anti-corrosion grease coating on overhead transmission lines is prone to peeling, loss, and aging failure after long-term service. Once the protective layer of the anti-corrosion grease fails, the conductor metal will be directly exposed to the corrosive atmosphere. Corrosive media such as moisture, oxygen, carbon dioxide, sulfur dioxide, and chlorides in the air will be adsorbed onto the conductor surface, forming an electrolyte film and causing severe electrochemical corrosion. For steel-cored aluminum stranded wires, galvanic corrosion will occur between the aluminum strands and the galvanized steel core due to the difference in electrode potential. White powdery corrosion products and pitting will appear on the surface of the aluminum strands. Once the galvanized layer of the steel core is damaged, corrosion will accelerate, resulting in a significant reduction in the overall tensile strength of the conductor, making the material brittle, and leading to serious accidents such as strand breakage and wire breakage. This greatly shortens the design service life of the conductor and seriously threatens the reliability and safety of the power grid.

[0003] Therefore, those skilled in the art are dedicated to developing a novel cable anti-corrosion grease coating component and device with high coating efficiency. Summary of the Invention

[0004] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a cable anti-corrosion grease coating assembly and device.

[0005] To achieve the above objectives, the present invention provides a cable anti-corrosion grease coating assembly, including an oil tank, a coating ring connected to the oil tank, and the coating ring and the oil tank being connected by an oil pipe;

[0006] Preferably, the coating ring includes an outer peripheral transmission pipe and an inner peripheral coating pad. The transmission pipe has a hollow flow channel inside, which is connected to the oil storage tank through the oil pipe. The side of the transmission pipe near the coating pad has several oil outlet holes.

[0007] Preferably, the coating ring includes a first coating half-ring and a second coating half-ring arranged symmetrically. The first coating half-ring and the second coating half-ring are connected to the frame through a first tensioning arm and a second tensioning arm, respectively. The first tensioning arm and the second tensioning arm have a pre-tightening force that brings the first coating half-ring and the second coating half-ring closer together.

[0008] The present invention also provides a cable anti-corrosion grease coating device, which further includes a frame, on which a cleaning component, a spraying component, a wiping component and a walking component are fixedly connected, and the walking component includes a front walking wheel mechanism and a rear walking wheel mechanism.

[0009] Preferably, the cleaning assembly includes a first mounting bracket, with cleaning brushes rotatably connected to both sides of the first mounting bracket along its length, and the axes of the two cleaning brushes being parallel to the axis of the overhead power line. Overhead power lines are exposed to wind and rain outdoors, and due to other factors, foreign matter may adhere to their surface. Cleaning the overhead power line with cleaning brushes before applying the anti-corrosion grease can effectively prevent foreign matter from reducing the adhesion of the grease and can increase the coverage area of ​​the anti-corrosion grease.

[0010] Preferably, the cleaning brush has a plurality of radially extending brush bodies circumferentially, and the radial lengths of adjacent brush bodies are not the same, so that the cross-sectional profile of the cleaning brush is helical.

[0011] Preferably, the spray washing assembly includes a gas compressor, a spray washing ring is connected to the gas compressor, and the spray washing ring is connected to the gas compressor via a gas pipe.

[0012] Preferably, the spray washing ring includes a first spray washing half-ring and a second spray washing half-ring arranged symmetrically. The first spray washing half-ring and the second spray washing half-ring are respectively connected to the frame through a third tension arm and a fourth tension arm with pre-tightening force. In the natural state, the third tension arm and the fourth tension arm bring the first spray washing half-ring and the second spray washing half-ring closer together to form a complete spray washing ring.

[0013] Preferably, the inner wall of the spray ring is provided with a plurality of nozzles at intervals, and the direction of the plurality of nozzles is offset from the center of the spray ring.

[0014] Preferably, the wiping assembly includes a second mounting bracket, with mounting heads on both sides along the length direction of the second mounting bracket, and wiping arc plates facing each other on both mounting heads, each of the wiping arc plates including a fixed back plate and an air-absorbing cotton.

[0015] Preferably, the frame is provided with a connecting ring, and a traction rope is detachably connected to the connecting ring.

[0016] The beneficial effects of this invention are as follows: The invention features a novel structure. Through the cooperation of its components, a uniform, continuous, and leak-free anti-corrosion grease protective film can be formed on the surface of overhead conductors. This greatly enhances the adhesion of the anti-corrosion grease and the durability of its protective effect, fundamentally improving protective reliability and extending conductor life. Simultaneously, it reduces the risks associated with manual high-altitude maintenance, improves maintenance efficiency and safety, and has significant market potential. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that in the description of the present invention, terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific manner. Therefore, they should not be construed as limitations on the present invention. Terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] like Figure 1As shown, the present invention provides a cable anti-corrosion grease coating assembly. The coating assembly 6 includes an oil tank 61 for storing anti-corrosion grease, and a coating ring 62 connected to the oil tank 61. The coating ring 62 and the oil tank 61 are connected by an oil pipe 63. Specifically, the coating ring 62 is composed of an outer transmission pipe 62a and an inner smearing pad 62b. The transmission pipe 62a has a hollow flow channel (not shown in the figure), which is connected to the oil tank 61 through the oil pipe 63. The side of the transmission pipe 62a near the smearing pad 62b is also provided with several oil outlet holes (not shown in the figure), so that the anti-corrosion grease in the oil tank 61 can enter the hollow flow channel along the oil pipe 63 and wet the smearing pad 62b through the several oil outlet holes. In this embodiment, the coating ring 62 is fitted around the outer periphery of the overhead conductor 8. The inner ring of the coating ring has a smearing pad that contacts the outer periphery of the overhead conductor 8, evenly applying the anti-corrosion grease to the outer periphery of the conductor 8. This design effectively prevents missed coating and removes excess grease from the surface of the overhead conductor 8. To facilitate the use of the coating assembly 6, the coating ring 62 consists of a symmetrically arranged first coating half-ring 621 and a second coating half-ring 622, which are connected to the frame 1 via a first tensioning arm 623 and a second tensioning arm 624, respectively. The first tensioning arm 623 and the second tensioning arm 624 have a pre-tightening force, causing the first coating half-ring 621 and the second coating half-ring 622 to close together naturally. In actual use, the coating ring 62 can be opened by deflecting the first tensioning arm 623 and the second tensioning arm 624 to both sides. After fitting it onto the overhead conductor 8 and releasing it, the coating ring 62 will automatically close and clamp the conductor under the pre-tightening force. In addition, to improve the coverage and uniformity of the anti-corrosion grease coating on the cable surface, the number of coating rings 62 can be increased as needed.

[0027] like Figure 2-3As shown, the present invention also provides a cable anti-corrosion grease coating device, including any of the cable anti-corrosion grease coating components described above, including a frame 1. In this embodiment, the frame 1, as the mounting base, is made of high-strength steel. A cleaning component 2, a spraying component 3, a wiping component 4, and a traveling component 5 are fixedly connected to the frame 1. The traveling component 5 includes a front traveling wheel mechanism 51 and a rear traveling wheel mechanism 52. The frame 1 can be suspended on the overhead conductor 8 and move along the overhead conductor 8 via the traveling component 5. Specifically, the traveling component 5 includes a front traveling wheel mechanism 51 arranged between the cleaning component 2 and the spraying component 3, and a rear traveling wheel mechanism 52 arranged between the wiping component 4 and the coating component 6, both of which adopt a wheel structure. This symmetrical layout aims to optimize load distribution and effectively reduce running resistance by replacing sliding friction with rolling friction, thereby ensuring that the entire device can move smoothly and stably on the overhead conductor 8. Simultaneously, through the coordinated operation of the cleaning component 2, spraying component 3, wiping component 4, and coating component 6, the overhead conductor 8 can be sequentially cleaned of debris, sprayed to remove residual stains, wiped of residual debris, and coated with anti-corrosion grease. This ultimately forms a gas-repellent film on the surface of the overhead conductor 8, preventing chemical reactions. Furthermore, the device includes a controller 9, which controls the operation of the aforementioned components, facilitating automated operation and ground control. Additionally, considering unforeseen circumstances such as remote control failure or power outage of power supply 12, a connecting ring 7 is provided on the frame 1, with a detachable traction rope (not shown in the figure) attached to it. In case of an accident, the coating device can be pulled using the traction rope to move it to a convenient location for removal.

[0028] like Figure 4-5As shown, the cleaning assembly 2 includes a first mounting frame 21. In this embodiment, the first mounting frame 21 serves as a mounting base and is fixedly connected to the frame 1. Columnar cleaning brushes 22 are symmetrically arranged on both sides of its length. The two cleaning brushes 22 are rotatably connected to the first mounting frame 21 via a rotating shaft (not shown in the figure) and are driven by a motor 23. The axes of the two cleaning brushes 22 are parallel to the axis of the overhead conductor 8. During operation, the motor 23 drives the two cleaning brushes 22 to rotate synchronously. The cleaning brushes 22 generate friction with the overhead conductor 8 through rotation, thereby removing attached materials. The rotation of the cleaning brushes 22 simultaneously provides initial velocity to the attached materials, and the airflow generated by the rotation promotes the separation of debris, preventing excessive accumulation on the brush body 22a. Furthermore, a plurality of radially extending brush bodies 22a are spaced apart on the outer periphery of the cleaning brushes 22. The radial length of adjacent brush bodies 22a is gradually varied, resulting in a helical cross-sectional profile of the cleaning brushes 22. In this embodiment, the brush body 22a is sheet-shaped; in other embodiments, it can be set as a column shape according to actual needs. The spiral layout design allows the contact length between the brush body 22a and the overhead wire 8 to change dynamically. While ensuring thorough cleaning, it can also alleviate the squeezing between adjacent brush bodies 22a, avoiding the phenomenon that the cleaning brush 22 cannot rotate normally due to excessive squeezing between the brush body 22a and the overhead wire 8.

[0029] like Figure 6As shown, the spray washing assembly 3 mainly consists of a gas compressor 31 and a spray washing ring 32, which are connected by an air pipe 33. In this embodiment, the gas compressor 31 serves as the air source, responsible for providing compressed air. It is installed below the frame 1 via a lifting frame 11, which also serves as an installation platform and houses the power supply 12 that supplies power to the entire device. The spray washing ring 32 includes symmetrically arranged arc-shaped first spray washing half-ring 321 and second spray washing half-ring 322. The first spray washing half-ring 321 and the second spray washing half-ring 322 are respectively connected to the frame 1 via a third tensioning arm 323 and a fourth tensioning arm 324 with pre-tension. In its natural state, the third tensioning arm 323 and the fourth tensioning arm 324 bring the first spray washing half-ring 321 and the second spray washing half-ring 322 closer together to form a complete spray washing ring 32. In this embodiment, the first tensioning arm 623, the second tensioning arm 624, the third tensioning arm 323, and the fourth tensioning arm 324 can all use a hinge structure with built-in torsion springs (not shown in the figure) or a slider guide mechanism equipped with compression springs (not shown in the figure) to achieve the pre-tensioning force setting. The elastic deformation of the springs provides a continuous closing torque or linear clamping force to each tensioning arm, ensuring that the connected semi-ring components remain stably clamped in their natural state. At the same time, in order to achieve a better spraying effect, the inner wall of the spraying ring 32 is also provided with several nozzles 325 at intervals. The spraying direction of the nozzles 325 is specially designed to deviate from the geometric center of the spraying ring 32. When spraying the overhead conductor 8, compressed gas enters the spraying ring 32 through the air pipe 33 and finally impacts its surface at an angle deviating from the axis of the overhead conductor 8, thereby achieving effective cleaning of the conductor.

[0030] like Figure 7 As shown, after being sprayed by the spray washing component 3, most of the overhead conductor 8 has been cleaned, but some debris may still remain. The wiping component 4 can wipe away this debris and allow the cleaned overhead conductor 8 to dry quickly, thereby improving the coating efficiency. Specifically, the wiping component 4 includes a second mounting bracket 41, with mounting heads 42 on both sides along its length. Wiping arc plates 43 are arranged facing each other on both mounting heads 42, and each wiping arc plate 43 includes a fixed back plate 431 and an air-absorbing cotton 432. Both wiping arc plates 43 are mounted on the mounting heads 42 at the lower part of the second mounting bracket 41 via mounting sleeves 44 provided on the side. In actual use, it can be assembled and fitted onto the overhead conductor 8.

[0031] This application features a novel structure. Through the coordinated operation of its components, a uniform, continuous, and seamless anti-corrosion grease protective film can be formed on the surface of the overhead conductor 8. This significantly enhances the adhesion of the anti-corrosion grease and the durability of its protective effect, fundamentally improving protective reliability and extending the conductor's lifespan. Simultaneously, it reduces the risks associated with manual high-altitude maintenance, improves maintenance efficiency and safety, and possesses significant market potential.

[0032] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
