Description

Technical Field

[0001] The utility model relates to the field of anti-corrosion treatment of wind power equipment, in particular to a spraying device for an anti-corrosion coating. Background Art

[0002] The main basis for anti-corrosion design of metal surfaces of wind turbines at present is wear stress (abrasion) in the atmosphere, which may cause damage to steel structures and blade surfaces due to friction between particles (such as sand) carried by the wind and the surface of the blades. In addition, damage can be caused by the impact of water droplets, hail, sandstorms and even larger objects such as flying birds. This is more common and obvious on the windward side and bottom of wind farm towers in desert Gobi, the surface of wind turbine blades, and the windward side of box-type floor-standing transformers. In particular, the tip speed of the blades often exceeds 70m / s. Wear can cause structural damage, reduced efficiency and loss. In desert Gobi areas, the above systems also have the defect of insufficient wind erosion resistance, especially on the near-ground part of the tower and the main windward side. In extreme cases, the coating is completely eroded by the wind, exposing the metal surface, resulting in rust and loss of appearance.

[0003] However, when the existing supersonic flame spraying equipment is used to spray anti-corrosion coatings on wind turbines, it is not convenient to fix the entire wind turbine equipment due to its large size. At the same time, most of the exterior of the wind turbine equipment is a curved structure, and the existing supersonic flame spraying equipment is not convenient to adjust the spraying distance according to the appearance of the wind turbine equipment when it is moved, which may cause uneven spraying of the anti-corrosion coating and inconsistent thickness of the sprayed coating.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figures 1-9 As shown, a spraying device for an anti-corrosion coating includes a base 1, a first bracket 2 is fixed at one end of the base 1, a second bracket 3 is fixed at the other end of the base 1, a spraying mechanism 4 and a supporting mechanism 6 for fixing the wind power equipment to be sprayed.

[0032] In this embodiment, the spraying mechanism 4 includes a spraying frame 41 slidably connected to the base 1, a sliding bar 42 is fixed on the top of the spraying frame 41, and a plurality of inclined tooth grooves are provided on the top of the sliding bar 42, a front bracket 43 is fixed to the rear side of the spraying frame 41, a rear bracket 44 is provided at the rear end of the front bracket 43, two guide bars 45 are fixed to the upper end of the rear bracket 44, and a water-cooling cover 46 is fixed to the front end of the two guide bars 45, and an adjustment seat 47 is fixed on one side of the water-cooling cover 46 to rest against the outside of the wind power equipment to be sprayed, and a spray gun 5 for HVOF supersonic flame spraying of the wind power equipment is installed inside the water-cooling cover 46, a sliding hole for the rear bracket 44 to slide back and forth is provided at the rear end of the spraying frame 41, a tensioning spring is provided between the front bracket 43 and the rear bracket 44, and a steel ball for reducing friction is embedded in the end of the adjustment seat 47 close to the wind power equipment to be sprayed, and the interior of the water-cooling cover 46 is a cavity structure, and the water-cooling cover 4 6 A pipe joint for cooling water flow is installed on the side away from the adjustment seat 47, a notch is provided on the rear bracket 44, and a guide groove for the sliding of the guide bar 45 is provided on the upper end of the rear bracket 44. A notch is provided in the middle position of the lower side of the second bracket 3 to facilitate the passage of the sliding bar 42. The movement of the sliding bar 42 drives the spraying frame 41 to move on both sides along the base 1. At the same time, the front end of the rear bracket 44 is driven to move into the guide groove of the spraying frame 41 by the tensioning spring. When the rear bracket 44 moves, the water-cooling cover 46 and the spray gun 5 are driven to move synchronously through the guide bar 45. As the water-cooling cover 46 moves, the end of its adjustment seat 47 is pressed against the outside of the wind turbine being sprayed, and the friction of the adjustment seat 47 moving on the outside of the wind turbine is reduced by the steel ball on the adjustment seat 47. Then, the distance from the spray gun 5 to the spraying position is adjusted in real time according to the shape of the wind turbine through the sliding rod 67.

[0033] In this embodiment: the support mechanism 6 includes two rotating seats 61 that are respectively rotatably connected to the first bracket 2 and the second bracket 3. The ends of the two rotating seats 61 that are close to each other are provided with three circumferentially distributed limiting grooves 62. A support arm 68 is hinged in each limiting groove 62. The end of the support arm 68 away from the rotating seat 61 is fixed with a support seat 69. The center positions of the two rotating seats 61 are threadedly connected with a threaded rod 66. The ends of the two threaded rods 66 that are close to each other are rotatably connected to the limiting sleeve. Three sliding rods 67 are fixed on the outside of the limiting sleeve. A sliding groove for the sliding rod 67 is provided on the support arm 68. A rotating disk 7 is fixed to the position of the rotating seat 61 close to the support arm 68. A dial rod 8 for moving the sliding bar 42 is fixed on the outside of the rotating disk 7. The second bracket 3 A worm gear is provided inside and fixed to the outside of the rotating seat 61, and a worm 65 is provided on the lower side of the worm gear to drive it to rotate. A rotating motor 64 is fixed to the input end of the worm 65. A threaded hole 63 is provided at the center of the rotating seat 61, and the threaded rod 66 is rotated to make it rotate at the center of the rotating seat 61. The rotation of the threaded rod 66 drives the limit sleeve and the three sliding rods 67 to approach or move away from the rotating seat 61. In this process, the three support arms 68 are opened or closed by moving the sliding rod 67 in the slide groove of the support arm 68, and then the support seat 69 is pressed against the inside of the pipe body of the wind power equipment by the three opened support arms 68 for tensioning and fixing, or the three support seats 69 are clamped and fixed to the wind power equipment by the three closed support arms 68.

[0034] Working principle: When in use, for the pipe body component of the wind power equipment, the two ends of the pipe body are respectively put on the support mechanism 6 of the first bracket 2 and the second bracket 3, and then the threaded rod 66 at the center position of the rotating seat 61 is rotated to drive the limit seat to move closer to the rotating seat 61. When the limit seat moves, it drives the three sliding rods 67 to move along the sliding groove of the support arm 68, and then the three support arms 68 are turned outward on the inside of the limiting groove 62. Then the three support arms 68 drive the corresponding support seats 69 to open outward at the same time, and let the support seats 69 rest against the inner wall of the pipe body, thereby completing the support and fixation of the pipe body of the wind power equipment;

[0035] After the tube body is fixed, push the spray rack 41 to slide along the top of the base 1 to a position close to the second bracket 3. At this time, let the spray gun 5 aim at the end of the wind power equipment. Then the rotating motor 64 drives the worm 65 to rotate, and the cooperation of the worm 65 and the worm gear drives the rotating seat 61 to rotate. At this time, the rotating seat 61 will drive the wind power equipment to rotate through the support arm 68. At this time, the spray gun 5 starts spraying and sends cooling water into the water-cooling cover 46 to cool the spray gun 5. In addition, when the rotating seat 61 rotates, the rotating disk 7 rotates synchronously with the rotating seat 61, and drives the lever 8 to rotate through the rotating rotating disk 7. When the rotating seat 61 rotates one circle, the lower end of the lever 8 will pass through the tooth groove of the sliding bar 42 again, and then the sliding bar 42 will drive the spray rack 41 to slide toward the first bracket 2. When the rotating seat 61 rotates the second circle, the lower end of the lever 8 will pass through the next tooth groove on the sliding bar 42, and then the spraying frame 41 drives the spraying gun 5 to switch to the next spraying position of the wind power equipment through the front bracket 43 and the rear bracket 44. In the process of the spraying gun 5 being driven by the spraying frame 41 to move, the front end of the rear bracket 44 is driven to move into the guide groove of the spraying frame 41 through the tensioning spring, and when the rear bracket 44 moves, the water-cooling cover 46 and the spraying gun 5 are driven synchronously to approach the wind power equipment through the guide bar 45. As the water-cooling cover 46 moves, the end of its adjustment seat 47 is pressed against the outside of the wind power equipment to be sprayed, and the friction force of the adjustment seat 47 moving on the outside of the wind power equipment is reduced by the steel ball on the adjustment seat 47, and then the distance from the spraying gun 5 to the spraying position is adjusted in real time according to the shape of the wind power equipment through the sliding bar 67;

[0036] When it is necessary to spray the non-tube components of the wind power equipment, the threaded rod 66 is rotated toward the inside of the two rotating seats 61, and then the limit sleeve is moved away from the rotating seat 61. At the same time, the limit sleeve drives the slide rod 67 to move along the slide groove of the support arm 68, and then the three support arms 68 drive the support seat 69 to clamp and fix the non-tube components of the wind power equipment, and then repeat the above steps to spray the wind power equipment.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
