Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine blade processing, and in particular to a device and a coating method for processing a surface coating of a wind turbine blade. Background Art

[0002] Wind turbine blades are the core components of wind turbines that convert natural wind energy into electricity for wind turbines. They are also the main basis for measuring the design and technical level of wind turbines. Wind turbine blades are components of wind turbines. As the number of wind turbines used increases, the demand for wind turbine blades also increases. Since most wind turbines are huge, the wind turbine blades they use must be huge. It is more laborious to spray anti-corrosion coatings by manpower. In order to improve the spraying efficiency of wind turbine blade anti-corrosion coatings, highly automated spraying equipment is required.

[0003] However, there are still some problems in the use of existing wind turbine blade surface coating processing equipment and coating methods: There is an anti-corrosion coating spraying device for wind turbine blades with a Chinese patent announcement number of CN211613132U, which includes a fixed base, support poles are fixedly installed at both sides of the upper surface of the fixed base, a threaded fixing rod is fixedly installed on the outer surface of the upper end of the support pole, two threaded collars are threadedly installed on the outer surface of the threaded fixing rod, a sliding groove is provided on the outer surface of the threaded collar, a nozzle fixing rod is provided on the lower surface of the threaded collar, a sliding connector is fixedly installed on the upper surface of the nozzle fixing rod, a spray nozzle is fixedly installed on the lower surface of the nozzle fixing rod, and a paint box is fixedly installed on the outer surface of one side of the fixed base; 1. The existing spraying equipment has a small spraying range, while the surface area of ​​the wind turbine blades is relatively large. The equipment is used for spraying wind turbine blades, which requires constantly changing the position of the nozzle to ensure complete coverage of the surface of the wind turbine blades. However, the constantly moving nozzle is difficult to ensure the same spraying thickness at multiple points, resulting in poor spraying quality; 2. Spraying equipment can only spray on relatively flat surfaces. However, due to the large curvature of the edge of the wind turbine blade, it is impossible to effectively and completely cover the surface with spraying. Moreover, spraying on the edge with a large curvature is prone to uneven spraying, which affects the overall spraying quality. 3. The existing spraying equipment cannot automatically flip over to complete the spraying of the other side after spraying on one side is completed. The overall efficiency is low. In addition, after one side is sprayed, it is not completely dry. If the spraying operation needs to be continued, the wind turbine blades need to be disassembled and replaced to replace the unsprayed blades. The overall low work efficiency increases the cost of disassembly and assembly.

[0004] In view of the above problems, innovative designs are carried out based on the original equipment and coating methods for processing the surface coating of wind turbine blades. Summary of the invention

[0020] By adopting the above technical solution, the movable range of the limit rod can be limited by the positioning block, and the upper end of the recovery box is connected to the limit rod, which can improve the stability of the horizontal movement of the recovery box.

When the movable frame translates, the limit shaft and the limit roller are driven to move synchronously, and the position of the limit roller is adjusted accordingly by using the design of the limit groove. Since the shape of the limit groove is similar to the edge of the wind turbine blade body, the activity trajectory of the limit roller is limited, so that the recovery box can move synchronously with the outer edge shape of the wind turbine blade, shield the unused nozzles and recover the spray liquid, thereby ensuring the overall spraying efficiency and reducing the waste of spray liquid.

[0023] A coating method for a wind turbine blade surface coating processing device, comprising the following steps: Step 1: First, use the clamping structure to clamp and fix the wind turbine blade body, pass the left end of the wind turbine blade body through the inside of the clamping seat, further rotate the positioning plate and fix it with the clamping seat to form a tubular structure, then rotate multiple sets of threaded screws in sequence, use the threaded screws to drive multiple sets of clamping plates to slide inside the clamping seat and the positioning plate respectively, so that the clamping plate contacts the left end of the wind turbine blade body and completes the clamping and fixing; Step 2: After the wind turbine blade body is clamped and fixed, the power motor is started to provide power for the liquid supply structure, and the power motor is used to drive the reciprocating screw to rotate, and the rotation of the reciprocating screw drives the piston to reciprocate inside the sealing tube, and the paint inside the liquid storage tank is transported to the first spray head assembly for spraying by the cooperation between the liquid inlet check valve, the liquid outlet check valve and the first conduit, and the second conduit cooperates to synchronously supply liquid to the second spray head assembly, so as to ensure that the upper end face and the side face of the wind turbine blade body can be sprayed synchronously; Step 3: While the power motor drives the reciprocating screw to rotate, the reciprocating screw is used to drive the driving pulley to rotate, and the driving pulley uses the transmission belt to drive the driven pulley, the transmission rod and the first gear to rotate synchronously, and the first gear cooperates with the first rack to move when the first gear rotates, and drives the movable frame to move synchronously to change the position of the first nozzle assembly and the second nozzle assembly; Step 4: After spraying one side of the wind turbine blade body, the movable frame moves from the right side to the left side of the equipment base, and drives the second rack to move to the left side synchronously, so that the second rack is engaged with the second gear. By using the cooperation of the inner ratchet and the pawl, the second gear can be used to drive the transmission worm to rotate in one direction, and the transmission worm can drive the transmission worm wheel and the clamping seat to rotate synchronously, thereby completing the flipping of the wind turbine blade body, and further performing continuous spraying on the back side.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: the equipment and coating method for processing the surface coating of wind turbine blades can effectively control the liquid supply amount during spraying by setting a piston-type liquid supply structure, and can increase the liquid supply amount accordingly according to the moving speed of the nozzle to ensure the overall spraying thickness and uniformity of the wind turbine blade body, improve the quality of spraying, and at the same time, a stirring structure is set to prevent the spraying liquid from settling and causing blockage of the spraying, thereby avoiding affecting the spraying quality.

[0025] 1. The spraying liquid supply structure can synchronously provide power for the movement of the nozzle assembly. The liquid supply and movement of the nozzle are carried out synchronously, so that the movement and liquid supply of the nozzle assembly are linked to each other. The movement speed and liquid supply amount of the nozzle assembly can be adaptively adjusted to improve the convenience of use. The number of nozzles for normal spraying can be controlled according to the shape of the wind turbine blade body to avoid waste of paint and recycle the paint sprayed by the excess nozzles; 2. The wind turbine blades are clamped and installed by setting a quick clamping structure, and the clamping structure is positioned and restricted in rotation by using a worm and worm gear structure. After the movable frame moves to the bottom end in the direction of the clamping structure, the gear rack structure is used to provide rotational power for the transmission worm, thereby automatically completing the flipping of the fan blades, thereby improving the convenience and automation of the overall operation. After the flipping, the reverse side of the wind turbine blade can be directly sprayed without waiting, thereby improving the efficiency of the overall operation. BRIEF DESCRIPTION OF THE DRAWINGS
