DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Reference Figures 1-3 As shown in the drawing, the present application provides a kind of shot blasting cleaning device for corrosion-resistant wind power tower cylinder inner wall, including: shot blasting pipe 6 and feeding pipe 5 connected in sequence, collecting barrel 3 is arranged outside shot blasting pipe 6, barrel mouth of collecting barrel 3 is formed in the end of shot blasting pipe 6 away from feeding pipe 5, collecting bin 15 for collecting shot is formed between collecting barrel 3 and shot blasting pipe 6, the bottom of collecting barrel 3 is equipped with collecting pipe 7 that is communicated with collecting bin 15.

[0021] As described above, using the shot peening pipe 6, feeding pipe 5, and collecting bucket 3 provided by this utility model, the shot peening pipe 6 is connected to the main unit of the shot peening machine through the feeding pipe 5, and the opening of the collecting bucket 3 is placed against the location to be cleaned on the inner wall of the wind turbine. The shot is sprayed onto the inner wall of the wind turbine through the shot peening pipe 6 to clean it. The waste shot is collected in the collecting bin 15 through the collecting bucket 3 and discharged outward through the collecting pipe 7.

[0022] Furthermore, for easier access to collection bucket 3, refer to... Figures 1-3 As shown, the top of the collection bucket 3 near the end of the feeding pipe 5 is also provided with a handle 4 for gripping, and both sides of the collection bucket 3 are provided with handles 8 for holding. The handle 4 makes it easy to lift the collection bucket 3, and the handles 8 further straighten the position of the collection bucket 3.

[0023] In this utility model, combined with Figures 1-4 As shown, the end of the collection bucket 3 facing away from the feeding pipe 5 is also fitted with a movable sleeve 2 for collection compensation. A rubber ring 1 is provided at the edge of the movable sleeve 2 facing away from the outside of the collection bucket 3. A spring 12 for length adjustment is provided between the movable sleeve 2 and the collection bucket 3.

[0024] Combination Figures 3-4 As shown, one end of the movable sleeve 2 is provided with an annular groove 13 to accommodate the spring 12, and one end of the collecting bucket 3 extends movably into the annular groove 13.

[0025] As described above, when using the movable sleeve 2 provided by this utility model, the movable sleeve 2 is telescopically installed on the collection bucket 3 through the annular groove 13. When the movable sleeve 2 is pressed against the inner wall of the wind turbine, the elastic force of the spring 12 makes the end of the movable sleeve 2 tightly abut against the inner wall of the wind turbine, avoiding any gap between the movable sleeve 2 and the inner wall of the wind turbine. At the same time, the rubber ring 1 seals the gap between the inner wall of the wind turbine and the movable sleeve 2, further filling the gap.

[0026] Furthermore, to facilitate the installation of the activity kit 2 onto the collection bucket 3, refer to... Figures 2-3 As shown, the movable sleeve 2 has an indented hole 10 extending into the annular groove 13 near the outer side of the collection bucket 3. A limiting groove 11 is formed on the outer wall of the collection bucket 3 along the axial direction, and a limiting bolt 9 extending into the limiting groove 11 is provided in the indented hole 10. The movable sleeve 2 is fixedly installed in the collection bucket 3 by the limiting bolt 9 and the limiting groove 11. When pressed against the inner wall of the wind turbine, the movable sleeve 2 extends and retracts on the collection bucket 3. At this time, the limiting bolt 9 moves in the limiting groove 11 to avoid interference with the extension and retraction of the movable sleeve 2.

[0027] Furthermore, in order to confine the waste shot blasting material to the movable sleeve 2 and the collection bucket 3, refer to Figures 3-4As shown, the inner side of the end of the movable sleeve 2 away from the collecting barrel 3 is further provided with a limiting ring 14 for limiting the discarded shot blasting. After the device is removed from the inner wall of the wind turbine, the device has a downward tilting action, at this time, the discarded shot blasting in the movable sleeve 2 and the collecting barrel 3 is limited in the collecting bin 15, avoiding the discarded shot blasting from pouring out through the end of the movable sleeve 2.

[0028] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
