Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower spraying technology, and in particular to a wind turbine tower spraying device. Background Technology

[0002] The wind turbine tower is a core component of wind power generation, primarily serving a supporting role and absorbing vibrations from the turbine to ensure stable operation. It is mainly constructed using CNC cutting, plate rolling, and welding processes to ensure the tower's precision and strength. Applying anti-corrosion coatings effectively isolates the tower from corrosive substances such as moisture, salt spray, and acid rain, preventing oxidation and rusting of the steel.

[0003] An existing wind turbine tower spraying device (Announcement No.: CN221360560U) delivers paint to a distribution ring and a distribution plate via a diaphragm pump. A second motor drives a threaded rod to rotate, causing the distribution ring and distribution plate to move up and down. Two sets of nozzles simultaneously spray the inner and outer walls of the tower. This eliminates the need for manual spraying, saving time and improving efficiency. The spraying process is automated, preventing the paint from affecting the health of operators. However, the open-type spraying method results in a large amount of paint scattering, wasting materials, polluting the environment, and creating harmful sprays that affect the physical and mental health of operators. Furthermore, dripping paint falls directly onto the conveyor belt, requiring additional cleaning and being non-recoverable, further exacerbating material waste and environmental burden. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wind turbine tower spraying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wind turbine tower spraying device includes a collector box, a support base, and a bracket. A top mounting plate is provided above the collector box, and a pull-out box is slidably installed at the bottom of the collector box. An electric push rod is installed on the outer side wall of the collector box via fasteners. The electric push rod is fixedly connected to the top mounting plate via an output shaft. A folding cover is provided between the lower end of the top mounting plate and the collector box. A filter box is installed on the side of the collector box away from the bracket via fasteners. A fan is provided on one side of the filter box. A dust suction hood is fixedly installed at the upper end of the top mounting plate. A dust suction hose is fixedly provided between the dust suction hood and the filter box. A second electric push rod is fixedly installed inside the bracket. A slider is fixedly installed on the second electric push rod. A first conveying pipe is fixedly installed on the slider, and a second spray head is fixedly installed at the bottom end of the first conveying pipe.

[0007] As a further embodiment of this utility model, the outer wall of the bracket is provided with a paint tank, the top of the paint tank is fixedly provided with a telescopic tube, and the other end of the telescopic tube is fixedly connected to the conveying pipe.

[0008] As a further embodiment of this utility model, a pump is fixedly installed on the telescopic pipe, the second conveying pipe is fixedly provided at one end of the first conveying pipe near the second nozzle, and the first nozzle is fixedly provided at the other end of the second conveying pipe.

[0009] As a further embodiment of this utility model, the two ends of the folding cover are respectively connected to the top mounting plate and the upper end of the collector box by Velcro, and the filter box is equipped with a filter screen by fasteners.

[0010] As a further embodiment of this utility model, the support base is fixedly connected to the inner wall of the collector box, and the bracket is fixedly connected to the outer wall of the collector box.

[0011] As a further embodiment of this utility model, the electric push rods are evenly distributed on the collector box, the slider is slidably connected to the bracket, and a dust extraction pipe is fixedly provided between the fan and the filter box.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In operation, the system consists of a folding hood, a top mounting plate, an electric actuator, a suction hose, a suction hood, a filter box, and a fan. When the electric actuator drives the top mounting plate upwards, it unfolds the folding hood to form a semi-enclosed space, preventing the spread of paint mist during spraying and avoiding direct contact between the paint and the external environment and operators. The folding hood, when folded, does not occupy extra space, facilitating the hoisting and transport of the tower. Simultaneously, when the fan operates, it creates negative pressure at the suction hood through the suction hose, causing the exhaust gases generated during spraying to naturally diffuse upwards and rise along the surface of the tower under the influence of negative pressure. After being effectively captured by the dust collection hood, the paint enters the filter box for processing. Through the cooperation of the two, the leakage of paint mist and exhaust gas is reduced, and the exhaust gas is concentrated and gathered upwards in the enclosed space, which improves the exhaust gas capture efficiency and ensures that most of the exhaust gas can be collected and treated, further reducing the impact on the environment and operators. In addition, through the V-shaped groove in the collection box and the pull-out box, the paint dripping or excess paint during the spraying process will slide down the surface of the support base to the V-shaped groove, and after being collected by the V-shaped groove, it flows to the pull-out box, realizing the effective recycling of paint waste and reducing raw material waste.

[0023] In use, after the tower is placed on the support base 2 using hoisting equipment, the electric push rods 102 are activated simultaneously to drive the top mounting plate 802 upward. The top mounting plate 802 then unfolds the folding cover 101, forming a closed space for protection.

The electric push rod 302 is activated to drive the slider 801 to move, placing the spray nozzle 106 and the spray... The first two nozzles 202 are adjusted to the preset telescopic position, and the pump 8 is started to work, delivering the paint to the two sets of nozzles to carry out automated spraying on the inner and outer walls of the tower. During the spraying process, the exhaust gas generated rises along the surface of the tower under negative pressure, is captured by the dust hood 105, and enters the filter box 104 for treatment through the dust suction hose 7. The excess paint slides down the surface of the support 2 into the V-shaped groove of the collection box 1, and flows into the pull-out box 103 after being collected by the V-shaped groove, so as to effectively recycle the waste.

[0024] In this embodiment, a paint tank 301 is provided on the outer side wall of the bracket 3, and a telescopic tube 303 is fixedly provided on the top of the paint tank 301. The other end of the telescopic tube 303 is fixedly connected to the conveying tube 201.

[0025] In use, the filter screen 4 inside the filter box 104 is composed of a coarse filter screen, an activated carbon filter screen and a fine filter screen stacked in sequence, which can filter paint particles and harmful volatile substances in the exhaust gas layer by layer, thereby improving the exhaust gas purification effect.

[0026] In this embodiment, a pump 8 is fixedly installed on the telescopic pipe 303, and a second delivery pipe 203 is fixedly installed at one end of the first delivery pipe 201 near the second nozzle 202, while a first nozzle 106 is fixedly installed at the other end of the second delivery pipe 203.

[0027] When in use, the folding cover 101 is made of flexible transparent PVC material, which can be flexibly unfolded or folded by the electric push rod 102, and allows the operator to clearly observe the internal spraying situation.

[0028] In this embodiment, the two ends of the folding cover 101 are connected to the top mounting plate 802 and the upper end of the collection box 1 by Velcro, and the filter box 104 is equipped with a filter screen 4 by fasteners.

When attached, they can be quickly fixed to form a closed space. After being torn open, they can be folded and stored flexibly.

[0034] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When preparing to spray paint the wind turbine tower, after the tower is placed on the support base 2 by the hoisting equipment, each set of electric push rods 102 is started simultaneously, driving the top mounting plate 802 to rise vertically. The top mounting plate 802 drives the folding cover 101 to unfold, forming a closed space for protection. Then, the fan 5 is turned on, so that the dust suction hood 105 forms a negative pressure in the closed space through the dust suction hose 7, ensuring that the spraying exhaust gas is effectively collected and treated. The electric push rod 302 is turned on, driving the slider 801 to move, adjusting the nozzle 106 and nozzle 202 to the preset extension position. The pump 8 is started to work and... The paint is delivered to two sets of nozzles for automated spraying of the inner and outer walls of the tower. During the spraying process, the exhaust gas generated rises along the surface of the tower under negative pressure, is captured by the dust collection hood 105, and then enters the filter box 104 for treatment through the dust collection hose 7. Excess paint slides down the surface of the support base 2 into the V-shaped groove of the collection box 1, and flows into the pull-out box 103 after being collected in the V-shaped groove. After the spraying operation is completed, the spraying equipment is turned off, the fan 5 runs for a delay to ensure that the exhaust gas is removed, and then it is turned off. Then the electric push rod 102 is started to drive the top mounting plate 802 to descend vertically, which drives the folding cover 101 to fold up. Finally, the tower is lifted and removed from the support base 2, and the collected paint waste is removed from the pull-out box 103 for treatment.
