Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, and in particular to automatic spraying equipment for the inner wall of an offshore large-megawatt wind power tower. Background Art

[0002] Wind power generation is a kind of clean energy. Wind power generation equipment includes many mechanisms, among which the wind power tower is the support. In order to avoid corrosion on the inside and outside of the wind power tower during the production process, anti-corrosion paint is generally sprayed on the inside and outside surfaces. There are currently two spraying methods, the first is manual spraying, and the second is mechanical spraying. Both spraying methods have disadvantages:

[0003] When using manual spraying, people can spray both the inside and the outside at the same time, but the efficiency of manual spraying is relatively low, and the harmful substances produced during spraying will seriously affect people's health.

[0004] When mechanical spraying is used, since the shape of the wind turbine tower is small at the top and large at the bottom, if the distance between the spraying tool and the material remains unchanged, the thickness of the spraying will be uneven, which will affect the quality of the product. Summary of the invention
