Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower production technology, specifically to a rapid coating device for the surface of wind turbine towers. Background Technology

[0002] As an important component of wind turbine generators, wind turbine towers are exposed to the outdoors for extended periods, subjected to harsh environmental conditions such as wind, rain, sun, salt spray, and sandstorms. This makes them highly susceptible to surface corrosion and wear, affecting the structural strength and service life of the tower. Therefore, during production, a rapid coating device for wind turbine tower surfaces is needed to spray anti-corrosion paint onto the surface of the towers, thereby extending their service life.

[0003] However, due to the poor mixing ability of existing rapid coating devices for wind turbine tower surfaces, it is not convenient to mix the coating according to the usage needs during actual use. This can easily cause the coating to settle and separate in the storage tank, affecting the uniformity of spraying. Utility Model Content

A support reinforcing block is fixedly installed at the bottom of the sliding screw block and the support sliding block. The top of the support reinforcing block and the support moving block are fixedly connected to the bottom of the paint box. A filling port is provided at the top of the paint box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This rapid coating device for wind turbine tower surfaces achieves efficient mixing of the coating through the combination of a first motor, a movable rotating rod, and stirring blades. The PLC controller can precisely control the speed and mixing time of the first motor. When the first motor is started, it drives the movable rotating rod to rotate, and the stirring blades at the outer end rotate accordingly, mixing the coating in all directions. This effectively avoids uneven spraying caused by coating layering. Compared with traditional devices, it greatly improves the quality and spraying effect of the coating, ensuring that the surface of the wind turbine tower is uniformly and effectively protected.

[0016] 2. This rapid coating device for wind turbine tower surfaces uses an adjustment mechanism consisting of an electric push rod, a push rod, and a support plate to flexibly adjust the position and height of the coating tube and the atomizing spray head. The electric push rod is extended and retracted by a PLC controller, which drives the push rod to move up and down, thereby adjusting the height of the support plate. This allows the atomizing spray head to adapt to the coating needs of wind turbine towers of different heights. At the same time, the horizontal adjustment structure consisting of a second motor, an adjusting screw, and a sliding screw block, together with the support rod and the support slider, can realize the horizontal movement of the coating box on the device body, facilitating reciprocating spraying operations on the wind turbine tower.

[0017] 3. This rapid coating device for wind turbine tower surfaces, through the cooperation of a liquid level sensor and a PLC controller, achieves intelligent monitoring of paint balance. The liquid level sensor detects the paint level inside the paint tank in real time and feeds the data back to the PLC controller. When the paint balance is lower than the preset value, the PLC controller can issue an alarm to remind the operator to add paint in time. In addition, the setting of paint pump, extraction pipe and telescopic conveying pipe ensures that paint can be stably and efficiently delivered to the atomizing spray head. Under the control of the PLC controller, the paint pump adjusts the extraction speed according to the spraying requirements, extracting paint from inside the paint tank and delivering it to the paint pipe through the telescopic conveying pipe, providing a stable paint supply for the spraying operation, avoiding the impact of insufficient paint supply on the spraying progress, and also reducing the work of frequently checking the paint balance manually, improving the automation level and management efficiency of the spraying operation.

The paint pump 13 is electrically connected to the PLC controller 3. A suction pipe 14 is fixedly installed on one side of the paint pump 13, extending into the interior of the paint tank 2. At the bottom end, a telescopic conveying pipe 15 is fixedly installed on the side of the paint pump 13 away from the electric push rod 8. The side of the telescopic conveying pipe 15 away from the paint pump 13 is fixedly connected to one side of the paint pipe body 11. A liquid level sensor 16 is fixedly installed on the inner wall of one side of the paint tank 2. The liquid level sensor 16 is electrically connected to the PLC controller 3. A first slide groove 17 is opened on one side of the top of the device body 1. A second motor 18 is fixedly installed on one side of the device body 1. The second motor 18 is electrically connected to the PLC controller 3. An adjusting screw 19 is fixedly installed on the output shaft end of the second motor 18. The adjusting screw 19 is located in the first slide groove 17. Inside device 7, a support connecting block 20 is fixedly installed on the inner wall of the first slide groove 17 on the side away from the second motor 18. An adjusting screw 19 is rotatably connected to one side of the support connecting block 20 on the side away from the second motor 18. A sliding screw block 21 is threadedly connected to the outer end of the adjusting screw 19. A second slide groove 22 is opened on the top of device body 1 on the side away from the first slide groove 17. A support rod 23 is fixedly installed inside the second slide groove 22.

A support reinforcement block 27 is fixedly installed at the bottom of the moving screw block 21 and the support slider 24. The top of the support reinforcement block 27 and the support moving block 26 are fixedly connected to the bottom of the paint tank 2. The top of the paint tank 2 is provided with an injection port 28. When the paint pump 13 is started, the paint in the paint tank 2 is drawn into the telescopic conveying pipe 15 and the paint pipe 11 through the extraction pipe 14 and sprayed out through the atomizing spray head 12. When the second motor 18 is started, the adjusting screw 19 is rotated, so that the sliding screw block 21 moves linearly on the adjusting screw 19, which drives the support reinforcement block 27 to move, and at the same time drives the support slider 24 to move on the support rod 23.

[0026] Working Principle: When spraying the surface of a wind turbine tower, the device is first stably installed in the desired location, matching the horizontally placed wind turbine tower. The wind turbine tower is placed horizontally on an adjustable rotating base. An external power supply is then connected to power the equipment on the device. An appropriate amount of paint is injected into the paint tank 2 through the injection port 28. The first motor 4 is started to rotate the movable rod 5. Simultaneously, the movable rod 5 rotates, driving the stirring blades 7 to rotate, which uniformly mix the paint. Then, the paint pump 13 is started to draw the paint from the paint tank 2 through the extraction pipe 14 into the telescopic conveying pipe 15 and the paint pipe body 11, which is then sprayed out through the atomizing spray head 12 to spray the surface of the wind turbine tower. While spraying, the second motor 18 is started to rotate the adjusting screw 19, causing the sliding screw block 21 to move linearly on the adjusting screw 19, which in turn moves the support reinforcement block 27. At the same time, it moves the support slider 24 on the support rod 23, thereby moving the support moving block 26 in the third slide groove 25. This, in turn, moves the paint box 2 and the atomizing spray head 12, and performs transverse reciprocating spraying on the surface of the wind turbine tower. According to the spraying requirements, the electric push rod 8 is started to adjust the height of the push rod 9, which pushes the support cross plate 10 to move, thereby adjusting the height of the paint tube 11 and the atomizing spray head 12, so as to facilitate spraying different heights on the surface of the wind turbine tower. After spraying, the wind turbine tower is rotated as needed to spray the unsprayed surfaces.
