Description

Technical Field

[0001] The invention relates to the field of painting, and in particular to a device for spraying paint on the inner surface of a wind power tower. Background Art

[0002] The wind turbine tower is a connecting component between the wind turbine and the foundation ring. It mainly plays a supporting role in the wind turbine and absorbs the vibration of the unit. It is an important component of wind power generation equipment. Since the wind turbine tower works in the external environment for a long time, it is easily affected by natural factors and the surface is easily corroded. Therefore, when producing wind turbine towers, the surface of the tower needs to be painted to prevent the surface of the tower from being corroded.

[0003] However, there are certain defects when using existing equipment to spray paint the inner wall of a wind power tower. Since the wind power tower is conical and the inner diameters of different parts are different, the equipment is always located at the bottom of the wind power tower when spraying paint on the inner wall of the wind power tower. The amount of paint sprayed on the lower inner wall of the wind power tower is the same, but as the inner diameter increases, the paint outlet of the paint spraying equipment is farther away from the upper inner wall of the wind power tower, so that less paint is sprayed on the upper inner wall of the wind power tower, resulting in uneven paint spraying. Summary of the invention

[0004] In view of the defects in the prior art, the present invention provides a wind turbine tower inner surface painting device, which can automatically adjust the distance between the paint outlet and the upper and lower inner walls of the wind turbine tower as the inner diameter of the wind turbine tower increases, so that the paint spraying is more uniform.

When the inner diameter of the wind power tower becomes larger, the paint outlet will be closer to the inner wall of the wind power tower, making the paint spraying more uniform.

[0031] The two inclined surface blocks 81 are both provided with inclined surfaces.

[0032] Application method: Initially, the vehicle body 1 is located inside the wind power tower and at the end with a smaller inner diameter. The staff first connects one end of the pressure pump 4 to the paint to be sprayed, and then starts the double-axis motor 3. The rotation of the output shaft of the double-axis motor 3 will drive the fixed bevel gear 6 connected to it to rotate, and the rotation of the fixed bevel gear 6 connected to the output shaft of the double-axis motor 3 will drive another fixed bevel gear 6 to rotate, and the rotation of the other fixed bevel gear 6 will drive the wheel 2 connected to it to rotate, and the rotation of the wheel 2 connected to the other fixed bevel gear 6 will drive the other wheel 2 to rotate, thereby driving the vehicle body 1 to the wind power tower with a larger inner diameter.

[0033] The rotation of the bevel gear transmission shaft 73 will drive the screw column 83 connected thereto to rotate, and the rotation of the rotating tube 74 will drive another screw column 83 to rotate. The rotation of the two screw columns 83 will respectively drive the connected moving rods 82 to move in the direction close to the atomizing nozzle 75. While the two moving rods 82 move in the direction close to the atomizing nozzle 75, they will move upward along the inclined surface block 81, and then drive the bevel gear transmission shaft 73 and the rotating tube 74 to move upward. The upward movement of the bevel gear transmission shaft 73 will drive the connecting frame 84 to move upward. The upward movement of the connecting frame 84 will drive the moving bevel gear 72 to move upward. The upward movement of the rotating tube 74 will drive the supporting guide tube 5 and the atomizing nozzle 75 to move upward, so that the two ends of the atomizing nozzle 75 are respectively at the same distance from the upper and lower inner walls of the wind power tower, thereby making the upper and lower inner walls of the wind power tower more evenly sprayed with paint.

[0034] Embodiment 2: Based on embodiment 1, Figure 5-Figure 6 As shown, an extension mechanism 9 is also included. The extension mechanism 9 is arranged on the rotating mechanism 7. The extension mechanism 9 includes a guide plate 91, a pushing frame 92, a guide rod 93 and a reset spring 94. Two guide plates 91 are connected to the upper side of the vehicle body 1 by bolts. The pushing frame 92 is rotatably connected to the rotating tube 74. Two guide rods 93 are slidably connected to the atomizing nozzle 75. Both guide rods 93 are slidably connected to the pushing frame 92. A reset spring 94 is connected between the atomizing nozzle 75 and the pushing frame 92 by a hook. The reset spring 94 is used for resetting the pushing frame 92. The reset spring 94 is sleeved on the rotating tube 74.

[0035] The upward movement of the rotating tube 74 will drive the pushing frame 92 to move upward. The upward movement of the pushing frame 92 will contact the two guide plates 91. The two guide plates 91 will squeeze the pushing frame 92 and push it to move toward the direction close to the atomizing nozzle 75. The return spring 94 is compressed, and the movement of the pushing frame 92 toward the direction close to the atomizing nozzle 75 will drive the two guide rods 93 to move toward the inner wall of the wind power tower. When the inner diameter of the wind power tower becomes larger, the paint outlet will be closer to the inner wall of the wind power tower, making the paint spraying more uniform.

[0036] Embodiment 3: Based on embodiment 2, Figure 7-Figure 10As shown, it also includes a pressing mechanism 10, the pressing mechanism 10 is arranged on the rotating mechanism 7, the pressing mechanism 10 includes a guide ring 101, a limiting rod 102, a sealing block 103, a baffle 104, a compression spring 105 and a pressure spring 106, the guide ring 101 is rotatably connected to the rotating tube 74, the limiting rod 102 is connected to the upper side of the vehicle body 1 by bolts, the limiting rod 102 is slidably connected to the guide ring 101, the atomizing nozzle 75 is connected to two sealing blocks 103 by bolts, and the two The sealing block 103 is slidably connected with a baffle 104, and the two baffles 104 are slidably connected to the atomizing nozzle 75. The two baffles 104 are in contact with the guide ring 101. A compression spring 105 is connected between one of the baffles 104 and the atomizing nozzle 75 via a hook, and the compression spring 105 is used to reset the adjacent baffle 104. A pressure spring 106 is connected between the other baffle 104 and the atomizing nozzle 75 via a hook, and the pressure spring 106 is used to reset the other baffle 104.

[0037] Initially, the baffle 104 located at the top contacts the upper half of the guide ring 101, and the baffle 104 located at the bottom contacts the lower half of the guide ring 101. Since the lower half of the guide ring 101 is thicker than the upper half, the guide ring 101 will push the baffle 104 located at the bottom to move closer to the atomizing nozzle 75. The pressure spring 106 is compressed, and the baffle 104 located at the bottom blocks part of the cross section of the atomizing nozzle 75, so that less paint is sprayed from the bottom. The rotation of the atomizing nozzle 75 will drive the two sealing blocks 103 and the two baffles 104 to rotate together. The baffle 104 located at the bottom will contact the upper half of the guide ring 101, and the reset of the pressure spring 106 will drive it The baffle 104 that was previously located at the bottom is reset, so that the baffle 104 that was previously located at the bottom no longer blocks a partial cross-section of the atomizing nozzle 75, so that more paint is sprayed from the top, and at the same time, the baffle 104 that was previously located at the top will contact the lower half of the guide ring 101, and the guide ring 101 will push the baffle 104 that was previously located at the top to move toward the atomizing nozzle 75, and the compression spring 105 is compressed. The baffle 104 that was previously located at the top will block a partial cross-section of the atomizing nozzle 75, so that less paint is sprayed from the bottom, thereby spraying more paint on the upper inner wall of the wind turbine tower, preventing insufficient paint spraying on the upper inner wall of the wind turbine tower due to the falling of the sprayed paint, and further making the paint spraying more uniform.

[0038] Embodiment 4: Based on the embodiment 3, Figure 5As shown, it also includes a guide rod 111, a support rod 112 and a support spring 113. The upper side of the vehicle body 1 is connected to two guide rods 111 by bolts. The two guide rods 111 are vertically arranged. The two guide rods 111 are slidably connected to the support rods 112. One of the support rods 112 is rotatably connected to the bevel gear transmission shaft 73, and the other support rod 112 is rotatably connected to the rotating tube 74. The two support rods 112 and the guide rods 111 are connected to support springs 113 through hooks. The support springs 113 are used to reset the support rods 112.

[0039] The upward movement of the bevel gear transmission shaft 73 will drive the support rod 112 connected thereto to move upward, and the upward movement of the rotating tube 74 will drive another support rod 112 to move upward. The upward movement of the two support rods 112 will respectively stretch the connected support springs 113, so that the two support rods 112 can respectively provide better support for the bevel gear transmission shaft 73 and the rotating tube 74.

[0040] Embodiment 5: Based on Embodiment 4, Figure 6 As shown, a nozzle 12 is also included, and one end of the two guide rods 93 is connected to the nozzle 12 by bolts.

[0041] The two nozzles 12 can diffuse the paint sprayed from the atomizing nozzle 75, so that the inner wall of the wind power tower can be sprayed with paint more quickly, thereby improving the painting efficiency.
