Description

Technical Field

[0001] The present invention relates to the technical field of spraying processing, in particular to an automatic spraying device. Background Art

[0002] Wind turbine towers are the tower poles for wind power generation, which mainly play a supporting role in wind power generation. Wind turbine towers are mainly used outdoors in harsh environments and need to be treated with anti-rust spraying.

[0003] Wind turbine towers are typically sprayed manually or mechanically. Manual spraying involves building a scaffolding around the tower, with operators climbing up different levels to spray the corresponding locations, which is labor-intensive. Mechanical spraying involves securing the tower and then spraying the tower using spray equipment that moves along its axis or rotates along its own axis. For example, Chinese patent publication number CN118341595A discloses a rotary support device for spraying wind power towers, which can realize the functions of automatic spraying and automatic cleaning of the outer wall of the tower. However, this structure still has the following shortcomings: 1. Since the power tower is clamped and fixed by rotating wheel rings at both ends, when hoisting the power tower, it cannot be lifted from both ends of the power tower, and can only be tied to the body of the power tower with steel ropes, and the power tower needs to be lifted before it can be tied, which makes the operation cumbersome and inefficient; 2. Since the cleaning ring and the paint spray head only start to move a certain distance after the power tower rotates one circle, the axial direction of the power tower is fully wiped, cleaned and sprayed in sequence. Although cleaning and spraying can be achieved, the efficiency of cleaning and spraying is low. Summary of the Invention

[0034] Among them, the spraying device includes a sliding seat 4 connected to the driving device, and an arc frame 5 is movably arranged on the sliding seat 4, and a spray gun 6 is arranged at the upper and lower ends of the arc frame 5; during the spraying operation, the two spray devices are driven inward to the two sides of the wind turbine tower 100 by the first driving device, and then the movable seat 3 slides along the linear track 2, that is, moves along the axial direction of the wind duct tower 100, and at the same time the wind turbine tower 100 rotates, thereby spraying the outer wall of the wind turbine tower 100 in all directions; in addition, the spraying device includes an arc frame 5 and a spray gun 6 arranged at the upper and lower ends of the arc frame 5, that is, a total of four spray guns 6 are arranged, and the four spray guns 6 are evenly distributed along the circumference of the outer wall of the wind turbine tower 100, so that the outer wall of the wind turbine tower 100 can be sprayed evenly and efficiently.

[0035] Furthermore, a transmission assembly is provided between the two rotating support seats 1 and on the left and right sides. The transmission assembly is connected to the arc frame 5, and when the movable seat body 3 moves back and forth along the linear track 2, the arc frame 5 can be driven by the transmission assembly to swing back and forth, that is, the spray gun swings while moving along the straight line to spray, thereby greatly improving the efficiency and effect of spraying.

[0036] See also Figure 1-5 、7- Figure 9 As shown, a rotating shaft 21 is provided at the outer end of the arc frame 5 , and the rotating shaft 21 is rotatably provided on the sliding seat 4 .

[0037] Furthermore, the transmission assembly includes a vertical fixed plate 31 provided on one side of the rotating support seat 1 in front and back, a horizontal cross plate 32 is connected between the two vertical fixed plates 31, a wave groove 33 extending in the front-to-back direction is provided on the horizontal cross plate 32, a first extension plate 34 is provided on one side of the rotating shaft 21, a first slide groove 35 is provided on the first extension plate 34, a top plate 36 is provided on the upper end of the sliding seat 4, a second slide groove 37 extending in the left-right direction is provided on the top plate 36, and a first slide groove 37 slides in the second slide groove 37. The sliding member 38 is provided with a second extension plate 39 on one side of the first sliding member 38, and a first guide rod 310 and a second guide rod 311 are respectively provided at the lower end of the second extension plate 39. A connecting entrance 312 connected to the wave groove 33 is provided at one end of the horizontal cross plate 32, and the second guide rod 311 can enter the wave groove 33 through the connecting entrance 312. The first guide rod 310 is movably provided in the first sliding groove 35, and a first spring 313 is provided in the second sliding groove 37 and on both sides of the left and right sides of the first sliding member 38.

[0038] The working principle of the transmission assembly is as follows:

[0039] First, the two sliding seats 4 are driven inward by the first driving device to move relative to each other, so that the arc frame 5 and the wind turbine tower 100 are on the same axis. At this time, the second guide rod 311 is located in the connecting entrance 312, and then the movable seat body 3 is moved in the linear track 2 to allow the second guide rod 311 to enter the wave groove 33. Then, under the action of the wave groove 33, the second guide rod 311, the second extension plate 39, the first guide rod 310 and the first sliding member 38 are reciprocated left and right, and under the action of the first guide rod 310 and the first slide groove 35, the rotating shaft 21 is driven to rotate back and forth, thereby driving the arc frame 5 to swing back and forth, realizing the reciprocating swing spraying of the spray gun 6.

[0040] Under the action of the first spring 313 and in the absence of external force, the first sliding member 38 remains stationary, which indirectly keeps the second guide rod 311 stationary, making it easier for the second guide rod 311 to enter the wave groove 33 from the connecting inlet 312.

[0041] See also Figure 1-Figure 4As shown, a third slide groove 41 extending along the left and right directions is provided on the inner side of the upper ends of the two vertical fixed plates 31, and a second sliding member 42 slides in the two third slide grooves 41. The two ends of the horizontal cross plate 32 are correspondingly connected to the second sliding member 42, and a wiping cloth 43 is provided on the inner side edge of the horizontal cross plate 32. When the second sliding member 42 slides inward in the third slide groove 41, the wiping cloth 43 can rest on the outer surface of the wind turbine tower 100. A second spring 44 is provided in the third slide groove 41. The second spring 44 is used to push the horizontal cross plate 32 outward so that the wiping cloth 43 remains disengaged from the wind turbine tower 100.

[0042] According to the above structure, that is, when the outer wall of the wind turbine tower 100 needs to be cleaned and wiped, the spraying device can be driven inward by the first driving device. At this time, the horizontal cross plate 32 can be pushed by the second guide rod 311 to allow the horizontal cross plate 32 to move inward along the third slide groove 41, and finally the wiping cloth 43 on the inner side of the horizontal cross plate 32 can be placed against the outer wall of the wind turbine tower 100. Finally, by rotating the wind turbine tower 100, the outer wall of the wind turbine tower 100 can be quickly cleaned, and the cleaning efficiency is extremely high.

[0043] After the cleaning is completed, the spraying device is driven to move outward by the first driving device, and the horizontal cross plate 32 is moved outward and reset under the action of the second spring 44 .

[0044] Thus, through clever mechanical design, the horizontal cross plate 32 can play a transmission role as well as a cleaning role, which greatly improves work efficiency and reduces the cost of equipment manufacturing.
