[0023] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] Specific embodiments of the portable fan bolt oil stain cleaning device provided by this utility model: Please see Figure 1-7 A portable fan bolt oil stain cleaning device includes a cleaning cylinder 1; the cleaning cylinder 1 is a circular cylindrical structure, with one end closed and the other end having an opening that allows bolts to enter.

[0025] The cleaning cylinder 1 is connected to an adapter 2 at its closed end. The adapter 2 is connected to the cleaning cylinder 1 by a thread. One end of the adapter 2 has an external thread. The closed end of the cleaning cylinder 1 is tapered and has an internal thread blind hole. The adapter 2 is used to connect to an electric drill. Through the threaded connection structure, adapters 2 with different shapes of external threads can be replaced to connect to different electric drills, improving compatibility.

[0026] In this embodiment, the other end of the adapter 2 is a triangular prism structure, which can be inserted into the electric drill for stable and secure clamping by the drill's jaws. The electric drill drives the cleaning cylinder 1 to rotate and clean oil stains from the outside of the bolt. The direction of loosening the threaded connection of the adapter 2 is opposite to the rotation direction of the electric drill to prevent the threaded connection from loosening during operation.

[0027] The cleaning cylinder 1 has several detachable brushes 4 inside, and a side cover plate 3 is provided on the side wall of the cleaning cylinder 1. The side cover plate 3 can be opened and closed to facilitate the loading and unloading of the brushes 4 inside the cleaning cylinder 1.

[0028] The cleaning cylinder 1 has a through hole on its side wall. One edge of the side cover plate 3 is hinged to the cleaning cylinder 1 and covers the through hole on the side wall of the cleaning cylinder 1. The side cover plate 3 has an arc-shaped plate structure. When the side cover plate 3 is opened, the internal brush 4 is exposed. When the side cover plate 3 is closed, it serves as the side wall of the cleaning cylinder 1 and surrounds the bolt.

[0029] A first perforated plate 6 is provided at the center of the other edge of the side cover plate 3, and a second perforated plate 7 corresponding to the first perforated plate 6 is provided on the outer side of the cleaning cylinder 1. There are two second perforated plates 7, which are arranged in parallel and spaced apart. Both the first perforated plate 6 and the second perforated plate 7 have through holes in their centers. When the side cover plate 3 is closed, the first perforated plate 6 extends between the two second perforated plates 7, and the side cover plate 3 is positioned by a wire 8 passing through the first perforated plate 6 and the second perforated plate 7. In some other embodiments, pins and cotter pins can be used to position the first perforated plate 6 and the second perforated plate 7, thereby ensuring the stability of the side cover plate 3 after it is closed.

[0030] The brush 4 is distributed circumferentially and extends axially along the inner side of the cleaning cylinder 1; the brush 4 includes a carrier strip 41, on which hard bristles 42 are mounted; the hard bristles 42 extend toward the center of the cleaning cylinder 1 and can contact the bolts that need to be cleaned to achieve the cleaning work. The side of the carrier strip 41 facing away from the hard bristles 42 has an arc-shaped surface that fits against the inner wall of the cleaning cylinder 1.

[0031] The carrier strip 41 is detachably connected to the inner side of the cleaning cylinder 1. Specifically, both ends of the inner side of the cleaning cylinder 1 are provided with several positioning posts 9, and the end of the carrier strip 41 is provided with positioning holes 10 for the positioning posts 9 to pass through. The positioning holes 10 cooperate with the positioning posts 9 to achieve axial positioning of the carrier strip 41.

[0032] The cleaning cylinder 1 is provided with several retaining springs 11 that hold the carrier strips 41 inside the cleaning cylinder 1. The retaining springs 11 are distributed at intervals along the axial direction of the cleaning cylinder 1. The retaining springs 11 will make the carrier strips 41 stick to the inner wall of the cleaning cylinder 1, thereby achieving radial positioning of each brush 4.

[0033] The carrier strip 41 is provided with a limiting groove 12 for axially limiting the snap ring 11. The outer ring edge of the snap ring 11 passes through the limiting groove 12 to prevent the snap ring 11 from moving axially. The cleaning cylinder 1 is provided with top blocks 13 for limiting the two ends of the snap ring 11. The top blocks 13 are in pairs, and each pair of top blocks 13 corresponds to the two ends of the snap ring 11 to ensure the accurate position of the snap ring 11.

[0034] During disassembly, remove the retaining ring 11 to take out each brush 4, making it easy to thoroughly clean and replace the brush 4.

[0035] The inner side of the opening end of the cleaning cylinder 1 is provided with a collar 5 that is fitted on the outside of the bolt. Since the inner diameter of the cleaning cylinder 1 is larger than the outer diameter of the bolt being cleaned, when the cleaning cylinder 1 is driven to rotate by the electric drill, in order to ensure the stability of the rotation of the cleaning cylinder 1, the collar 5 is fitted on the outside of the bolt. The collar 5 rotates along the outside of the bolt, which can make the cleaning cylinder 1 rotate stably.

[0036] To enable the collar 5 to accommodate bolts of different outer diameters and to ensure that the collar 5 surrounds the bolts when the cleaning cylinder 1 rotates, in this embodiment, the collar 5 includes several circumferentially distributed sector plates 51. The sector plates 51 are hinged to the inner side of the cleaning cylinder 1, and an elastic band 53, which is an elastic rubber band, connects adjacent sector plates 51. When no external force is applied, the elastic band 53 minimizes the size of the hole at the center of the sector plate 51, i.e., the inner ring hole of the collar 5. When a bolt with a larger outer diameter passes through the collar 5, the sector plates 51 of the collar 5 flip open, and the elastic band 53 causes the center end of the sector plate 51 to fit against the outside of the bolt. This allows for the passage of bolts with different outer diameters while ensuring stable rotation of the cleaning cylinder 1.

[0037] A rigid rubber plate 52 is provided at the center end of the sector plate 51, and the rigid rubber plate 52 is connected to the sector plate 51 by screws. The rigid rubber plate 52 rotates in contact with the bolt, generating friction. It can be replaced after wear, thus protecting the sector plate 51. In addition, the rigid rubber plate 52 rotates outside the bolt, which also has a certain cleaning effect on the bolt.

[0038] Specific implementation details: In a wind power project in Xinjiang, each wind turbine assembly includes foundation anchor bolts, five tower connecting bolts, nacelle and tower connecting bolts, three blades and hub connecting studs, and main shaft connecting bolts, totaling more than 800 bolts per wind turbine assembly.

[0039] The initial stage of this project involves the hoisting of wind turbines. Before each construction process, the bolts used must be cleaned to ensure construction quality and installation progress. This utility model was designed to improve the construction efficiency and ensure construction quality during the wind turbine hoisting preparation stage. Before construction, place the equipment in place and select the appropriate electric drill (DC / AC) according to the construction site conditions to meet the construction requirements; During construction, a dedicated person is assigned to use this equipment to clean the bolts. This equipment is highly efficient and easy to operate. It can be carried out simultaneously with other preparatory work for wind turbine hoisting, which greatly improves work efficiency and avoids wasting manpower and resources by waiting for cleaning before hoisting. Once this section is completed, it will be moved to the next construction site for cleaning, making it easy to carry and move.

[0040] Portable wind turbine bolt oil stain cleaning equipment can meet the cleaning needs of various types of bolts in different parts of the wind turbine, greatly improving the efficiency of the preparatory work for wind turbine hoisting. At the same time, compared with traditional manual cleaning methods, the construction quality and efficiency are greatly improved.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
