[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. In the generator, the stator core is a key component. Existing stator cores are made by splicing two fan-shaped structures. After splicing, the stator sectors need to be stamped and painted. After stamping, a thin layer of water-soluble high-voltage insulating paint needs to be applied to the upper and lower surfaces of the stator sectors to ensure that the stator sectors are insulated from each other after stacking and to protect the material from corrosion.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-6 The utility model provides a technical solution: a wind turbine stator sector painting machine, comprising a supporting base 1, a first motor 2, a first bevel gear 3, a first threaded rod 4, a limiting rod 5, a movable block 6, a first transmission rod 7, a rotating wheel 8, a supporting frame 9, an upper paint barrel 10, a paint feeding groove 11, plastic bristles 12, a lower paint barrel 13, a fixing frame 14, a rotating shaft 15, a second transmission rod 16, a collecting port 17 and a collecting box 18, a first motor 2 is arranged in the supporting base 1, and a first bevel gear 3 is connected to the first motor 2, and a first threaded rod 4 is connected to the outer side of the first bevel gear 3 through a bevel gear, limiting rods 5 are connected on both sides of the first threaded rod 4, and movable blocks 6 are connected to the limiting rod 5 and the first threaded rod 4, and a motor is arranged in the movable block 6, and the motor is connected to the first transmission rod 7, The first transmission rod 7 and the upper rotating wheel 8 are driven to rotate by the motor, thereby driving the fan-shaped piece inside the rotating wheel 8 to rotate, and the first transmission rod 7 is connected to the movable block 6, and the first transmission rod 7 is connected to the rotating wheel 8, the outer side of the support base 1 is connected to the support frame 9, and the top of the support frame 9 is connected to the upper brush cylinder 10 through a rotating shaft, and a lower brush cylinder 13 is arranged under the upper brush cylinder 10, and a paint inlet trough 11 is arranged on the outer side of the upper brush cylinder 10 and the lower brush cylinder 13, and plastic bristles 12 are arranged at the bottom of the paint inlet trough 11, and the right side of the upper brush cylinder 10 is connected to the fixed frame 14 through a rotating shaft 15, and the right side of the rotating shaft 15 is connected to the second transmission rod 16, and the outer side of the second transmission rod 16 is connected to a motor, and a collecting port 17 is arranged on the support frame 9 at the bottom of the lower brush cylinder 13, and a collecting box 18 is arranged at the bottom of the collecting port 17.

[0023] The first motor 2 forms a gear transmission structure through the first bevel gear 3 and the bevel gear inside the first threaded rod 4, thereby driving the first threaded rod 4 to rotate through the gear structure.

[0024] The movable block 6 is threadedly connected to the first threaded rod 4, so that the movable block 6 moves along with the rotation of the first threaded rod 4. The movable block 6 forms a threaded movable structure on the support frame 9 through the first threaded rod 4 and the limiting rod 5. The limiting rod 5 is used to prevent the movable block 6 from rotating when the first threaded rod 4 rotates.

[0025] The upper brush cylinder 10 forms a rotating structure on the fixed frame 14 through the rotating shaft 15 and the second transmission rod 16, so that when the motor drives the rotating shaft 15 to rotate through the second transmission rod 16, the upper brush cylinder 10 can be turned over to facilitate the insertion of the fan-shaped piece.

[0026] The two sides of the lower brush barrel 13 are connected between the support frame 9 and the fixed frame 14 through a rotating shaft, so that it can move along with the rotation of the fan-shaped piece and paint the fan-shaped piece at the same time. The horizontal plane of the lower brush barrel 13 is higher than the horizontal plane of the first threaded rod 4 in the support frame 9, so that the fan-shaped piece can be supported by the lower brush barrel 13 to avoid contact with the first threaded rod 4 and damage to the paint. The paint inlet groove 11 on the outside of the lower brush barrel 13 is set on the upper side of the lower brush barrel 13 to prevent the paint from flowing along the plastic bristles 12 to the lower brush barrel 13.

[0027] The upper paint brush barrel 10 and the lower paint brush barrel 13 are painted through a loading structure composed of a paint inlet trough 11 and plastic bristles 12, and the connection between the bottom of the paint inlet trough 11 and the plastic bristles 12 is an open structure, so that the paint flows into the surface of the upper paint brush barrel 10 and the lower paint brush barrel 13 along the plastic bristles 12 through the opening at the bottom of the paint inlet trough 11, thereby reducing the splashing of paint and allowing the paint to stably and evenly cover the surface of the upper paint brush barrel 10 and the lower paint brush barrel 13.

[0028] Working principle: When using the wind turbine stator sector painting machine, first, start the motor on the outside of the second transmission rod 16 on the fixed frame 14, so that the motor drives the rotating shaft 15 to rotate through the second transmission rod 16, thereby rotating the upper brush cylinder 10 connected to the rotating shaft 15, thereby opening the clamp formed by the upper brush cylinder 10 and the lower brush cylinder 13, and then put the sector into the fixed frame 14, and control the motor on the outside of the second transmission rod 16 on the fixed frame 14 to reverse, so that the upper brush cylinder 10 rotates in the opposite direction to press the sector;

[0029] Then, the first motor 2 in the supporting base 1 is started, so that the first motor 2 drives the bevel gear at the front end of the first threaded rod 4 to rotate through the first bevel gear 3 at the top, thereby rotating the first threaded rod 4. As the first threaded rod 4 rotates, the movable block 6 connected thereto by threads moves inward with the assistance of the limiting rods 5 on both sides, thereby clamping the outer circle of the sector-shaped piece of the rotating wheel 8 through the movable block 6, and then the motor connected to the lower first transmission rod 7 in the rotating wheel 8 is started, so that the rotating wheel 8 drives the sector-shaped piece clamped inside to rotate, and the self-rotation of the sector-shaped piece will drive the upper brush cylinder 10 and the lower brush cylinder 13 clamped on the upper and lower surfaces to rotate;

[0030] While rotating, paint will be filled into the paint inlet groove 11 on the outside of the upper brush cylinder 10 and the lower brush cylinder 13, and then smeared on the upper brush cylinder 10 and the lower brush cylinder 13 along the bottom opening and the plastic bristles 12, and then covered on the upper and lower surfaces of the fan-shaped sheet through the contact between the upper brush cylinder 10 and the lower brush cylinder 13 and the fan-shaped sheet, and the paint dripping during the painting work will fall into the collecting port 17 of the bottom support frame 9, and then be collected by the collecting box 18 for regular treatment, and after the completion as scheduled, the motor on the outside of the second transmission rod 16 on the fixed frame 14 is started, so that the motor drives the rotating shaft 15 to rotate through the second transmission rod 16, thereby rotating the upper brush cylinder 10 connected to the rotating shaft 15, thereby opening the clamp formed by the upper brush cylinder 10 and the lower brush cylinder 13, so that the painted fan-shaped sheet can be directly dropped out through the lifting device and replaced with a new one, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
