[0002] Wind turbine tower is the tower pole of wind power generation, which mainly plays a supporting role in wind power generation. Wind turbine tower is mainly used in harsh outdoor environment and needs to be treated with anti-rust by spraying.

[0003] Wind turbine towers are usually sprayed manually or mechanically. Manual spraying involves building scaffolding around the wind turbine tower, and operators climbing up different levels of the scaffolding to spray the corresponding positions, which is labor-intensive. Mechanical spraying involves fixing the wind turbine tower, and then spraying the wind turbine tower by moving the spraying equipment along the axial direction of the wind turbine tower and rotating the wind turbine tower along its own axial direction. For example, the Chinese patent publication number is: CN118341595A, which 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, the 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.

[0033] like Figure 1-Figure 11 As shown, an automatic spraying device is disclosed, including a cylinder hanging assembly detachably connected to both ends of a wind power tower 100, and also including a rotating support seat 1 arranged at a front and rear interval for supporting and rotating the cylinder hanging assembly, a linear track 2 is connected between the two rotating support seats 1, a moving seat body 3 is slidably mounted on the linear track 2, and a spraying device and a first driving device that can slide left and right are spaced apart on the left and right sides of the moving seat body 3, and the first driving device is used to drive the two spraying devices to slide inward or inward relative to each other. Slide outwards against each other; firstly, through the setting of the rotating support seat 1 and the cylindrical lifting assembly, when the wind turbine tower 100 is lifted and sprayed, the cylindrical lifting assembly is first installed and connected to the two ends of the wind turbine tower 100, so there is no need to lift the wind turbine tower 100, and then lift it as a whole, and place the cylindrical lifting assembly directly on the rotating support seat 1, which is simple and convenient to operate; of course, when the cylindrical lifting assembly is placed, the first driving device has moved the two spraying devices outwards, and the wind turbine tower 100 can be directly lowered at this time.

[0034] Among them, the spraying device includes a sliding seat 4 connected to the driving device, an arc frame 5 is movably arranged on the sliding seat 4, and spray guns 6 are arranged at the upper and lower ends of the arc frame 5; during the spraying operation, the two spraying devices are driven inward to the two sides of the wind turbine tower 100 by the first driving device, and then the movable seat body 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, and the transmission assembly is connected to the arc frame 5. When the movable seat body 3 moves forward and backward along the linear track 2, the arc frame 5 can be driven to swing back and forth through the transmission assembly. That is to say, the spray gun swings while moving along a straight line for spraying, thereby greatly improving the efficiency and effect of spraying.

[0036] See also Figure 1-5 7- Fig. 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 disposed on the sliding seat 4 .

[0037] Furthermore, the transmission assembly includes a vertical fixing plate 31 arranged on one side of the rotating support seat 1 in front and back, a horizontal cross plate 32 is connected between the two vertical fixing plates 31, a wave groove 33 extending in the front-to-back direction is arranged on the horizontal cross plate 32, a first extension plate 34 is arranged on one side of the rotating shaft 21, a first slide groove 35 is arranged on the first extension plate 34, a top plate 36 is arranged on the upper end of the sliding seat 4, a second slide groove 37 extending in the left-right direction is arranged on the top plate 36, and a first slide groove 37 slides in the second slide groove 37. A 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 arranged 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 to move inwardly relative to each other through the first driving device, so that the arc frame 5 and the wind power 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 mobile 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 reciprocate 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 reciprocate, thereby driving the arc frame 5 to swing back and forth, thereby 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 is kept stationary, that is, the second guide rod 311 is indirectly kept stationary, so that the second guide rod 311 can 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-right direction 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, and 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 abut against the outer surface of the wind turbine tower 100, and 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 to say, when it is necessary to clean and wipe the outer wall of the wind turbine tower 100, the spray device can be driven by the first driving device to move inward. 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 pressed against the outer wall of the wind turbine tower 100. Finally, the outer wall of the wind turbine tower 100 can be quickly cleaned by rotating the wind turbine tower 100, and the cleaning efficiency is extremely high.

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

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

At the same time, under the action of the guide bevel 83 and the third guide rod 81, the telescopic rod 72 is driven to move along the radial direction of the cylindrical body 71, and then abuts against the inner wall of the wind turbine tower 100 through the support member 73, thereby realizing the connection and fixation between the cylindrical body 71 and the wind turbine tower 100.
