[0002] Wind turbines are mainly supported by the casing, which needs to be sprayed and painted during the manufacturing process to increase its corrosion resistance, so a spray painting device is used.

[0003] At present, the spray painting process of the wind turbine casing is to first place the wind turbine casing in a proper position, and then directly spray the paint on the inner and outer surfaces of the wind turbine casing through a spray tube. Since the inner and outer surfaces of the wind turbine casing need to be sprayed evenly, the conventional spraying process is relatively complicated, and it is not possible to quickly complete the spray painting of the wind turbine casing, and the efficiency is low. Therefore, a wind turbine casing spray painting device is proposed. Utility Model Content

At the same time, the motor and the paint supply pump connected to the spray pipes are turned on. The motor can drive the rotating plate and the mounting plate to rotate, so that the two spray pipes and the spray head rotate around the center of the wind turbine casing. The paint supply pump can draw paint into the interior of the paint spray pipe and the paint spray head, so that the inner and outer sides of the wind turbine casing can be sprayed with paint at the same time, thereby improving the efficiency of painting.

[0016] 2. The utility model uses a slide bar, a slider and a fixing bolt arranged on a rotating plate. Due to the different diameters of wind turbine casings, the positions of the two spray pipes need to be adjusted. By loosening the fixing bolts, the slider can be moved on the slide bar, so that the horizontal positions of the two spray pipes are adjusted and matched with the wind turbine casing of the corresponding size, which can ensure that the two spray pipes are respectively inserted into the inner and outer sides of the wind turbine casing of different sizes.

[0017] 3. The utility model is provided with a jack, a first magnet block and a second magnet block. Since the thickness of different wind turbine casings is different, the distance between the two spray heads can be finely adjusted.

[0018] 4. The utility model is provided with a placement net, a blower, a ventilation cavity and ventilation holes. After the wind turbine casing is sprayed and painted, the blower is turned on to blow gas into the ventilation cavity, and the gas then enters the ventilation cavity and is finally blown out through the ventilation holes. Due to the effect of the placement groove, the gas is blown upward and the wind turbine casing is blown and dried. BRIEF DESCRIPTION OF THE DRAWINGS
