[0002] A wind farm is a place that captures wind energy, converts it into electrical energy, and sends it to the power grid through transmission lines. Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source. Using wind power generation is very environmentally friendly, and the amount of wind energy is huge. Wind turbine towers are indispensable. Wind power generation towers, which are made of precast concrete components, mainly play a supporting role in wind turbine generator sets.

[0003] In the construction of wind turbine concrete towers, precast concrete tower sections are increasingly used to increase the height of wind turbines. Traditional wind turbine concrete towers require manual grouting, with workers manually pouring the grout bucket by bucket.

Detailed Implementation

[0028] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0030] like Figure 1-6 As shown, this embodiment of the invention provides a concrete feeding device for wind farm construction, including a feeding assembly 101. The feeding assembly 101 includes a moving disc 11, a mixing rod 12, a turntable 14, two guide columns 15, a drive motor 16, two pushing cylinders 17, a tension spring 18, a fixed box 19, a central gear disc 20, a limiting seat 22, an internal gear ring 23, three rotating shafts 24, three planetary gears 25, a limiting ring 29, and a guide sleeve 30.

[0031] Two push cylinders 17 are symmetrically fixedly connected to the upper surface of the moving disk 11. The guide post 15 is slidably connected to the inner wall of the guide sleeve 30. The tension spring 18 is sleeved on the outside of the guide sleeve 30. The limiting ring 29 is fixedly connected to the upper surface of the turntable 14. The outer walls of three planetary gears 25 are symmetrically meshed with the outer wall of the central gear disk 20 and the inner wall of the internal gear ring 23. Three rotating shafts 24 are symmetrically rotatably connected to the inside of the turntable 14. The top of the rotating shaft 24 is fixedly connected to the lower surface of the planetary gear 25. The top of the stirring rod 12 is fixedly connected to the bottom of the rotating shaft 24. The bottom of the limiting seat 22 is rotatably connected to the outer wall of the planetary gear 25. The central gear disk 20 is fixedly connected to the output shaft of the drive motor 16.

[0032] In one embodiment, a fixing box 19 is provided above the moving disk 11, and the lower surface of the fixing box 19 is attached to the upper surface of the moving disk 11. The feeding assembly 101 also includes a hole 13, a mounting groove 26, a limiting groove 27 and an arc groove 28.

[0033] Holes 13 are evenly distributed on the outer wall of the stirring rod 12. The mounting groove 26 is provided on the lower surface of the moving disk 11. The limiting groove 27 is provided on the inner top wall of the mounting groove 26. The arc groove 28 is provided on the lower surface of the moving disk 11. The limiting seat 22 is slidably connected to the inner side wall of the limiting groove 27. The upper surface of the internal gear ring 23 is fixedly connected to the inner top wall of the mounting groove 26. The drive motor 16 is installed on the upper surface of the moving disk 11. The upper surface of the central gear plate 20 is rotatably connected to the inner top wall of the mounting groove 26. The outer wall of the limiting ring 29 is slidably connected to the inner side wall of the arc groove 28. The upper surface of the turntable 14 is attached to the lower surface of the moving disk 11. The bottom ends of the two guide pillars 15 are symmetrically fixedly connected to the upper surface of the moving disk 11.

[0034] By setting holes 13 on the outer wall of the mixing rod 12, when the mixing rod 12 mixes the concrete, the holes 13 can draw air bubbles in the concrete into the mixing rod 12, thereby increasing the density and uniformity of the concrete and improving the concrete pouring effect. The position of the planetary gear 25 can be limited by the cooperation of the limiting groove 27 and the limiting seat 22. The position of the turntable 14 can be limited by the cooperation of the arc groove 28 and the limiting ring 29. The central gear plate 20 is driven to rotate by the drive motor 16. With the cooperation of the central gear plate 20, the three planetary gears 25 and the internal gear ring 23, the three mixing rods 12 rotate around the axis of the turntable 14 while rotating on their own axis. Thus, the mixing rods 12 can mix the concrete to increase the density and uniformity of the concrete and improve the concrete pouring effect.

[0035] In one embodiment, the bottom end of the tension spring 18 is fixedly connected to the upper surface of the movable disk 11. The push cylinder 17, guide sleeve 30, and drive motor 16 are all located inside the fixed box 19. The stirring rod 12 is located below the turntable 14. By pushing the movable disk 11 downward with the push cylinder 17, the stirring rod 12 can be inserted into the concrete. The guide post 15 and guide sleeve 30 can play a guiding role, allowing the stirring rod 12 to move vertically downward. When the push cylinder 17 is reset, the tension spring 18 can play an auxiliary reset role, pulling the movable disk 11 upward to reset.

[0036] In one embodiment, a main body assembly 301 is mounted on the upper surface of the fixed box 19. The main body assembly 301 includes a concrete funnel body 31, four arc-shaped lifting rings 32, a discharge pipe 33, and a conical hopper 34.

[0037] The upper surface of the fixed box 19 is fixedly connected to the lower surface of the conical hopper 34. Four arc-shaped lifting rings 32 are symmetrically fixedly connected to the outer side wall of the concrete funnel body 31. The conical hopper 34 is fixedly connected to the lower surface of the concrete funnel body 31 and communicates with the concrete funnel body 31. The concrete funnel body 31 is made of stainless steel, which gives it good corrosion resistance, wear resistance and tensile strength. It is also not easy to attract dust and dirt, and is easy to clean and maintain.

[0038] In one embodiment, the top end of the feeding pipe 33 is fixedly connected to the outer wall of the conical hopper 34 and communicates with the conical hopper 34. The feeding assembly 101 is located below the main assembly 301. The top end of the tension spring 18 is fixedly connected to the lower surface of the conical hopper 34. The top ends of the two guide sleeves 30 are symmetrically fixedly connected to the lower surface of the conical hopper 34. The top ends of the two push cylinders 17 are symmetrically installed on the lower surface of the conical hopper 34. By pushing the moving disc 11 downward by the push cylinders 17, the concrete mixing action can be realized. When the push cylinders 17 are reset, the tension spring 18 can play an auxiliary reset role.

[0039] In operation, the present invention works as follows: Concrete is loaded into the concrete funnel body 31, and then a lifting rope is fixedly connected to the arc-shaped lifting rings 32 around the concrete funnel body 31. Through the cooperation of the lifting rope and the arc-shaped lifting rings 32, the entire material feeding device is hoisted to the top of the tower. The bottom end of the feeding pipe 33 is placed inside the tower. Since the conical hopper 34 is connected to the concrete funnel body 31, concrete flows out from the feeding pipe 33. As the concrete pouring time increases, an external switch activates the push cylinder 17, which pushes the moving disc 11 downwards. The moving disc 11 drives the drive motor 16, the turntable 14, and the stirring rod 12 downwards. When the moving disc 11 moves downwards, it causes the guide column 15 to slide within the guide sleeve 30. Through the cooperation of the guide column 15 and the guide sleeve 30, the moving disc 11 can move vertically downwards. The drive motor 16 is controlled by a switch. The central gear disk 20 rotates, and the central gear disk 20 drives three planetary gears 25 through its teeth. Since the planetary gears 25 mesh with both the central gear disk 20 and the internal gear ring 23, they rotate around the central gear disk 20 while rotating on their own axis. The planetary gears 25 drive the rotating shaft 24, and under the combined action of the three rotating shafts 24, the turntable 14 rotates. The position of the turntable 14 can be limited by the limiting ring 29. At the same time, the three stirring rods 12 rotate around the axis of the turntable 14 while rotating on their own axis. The stirring rods 12 can then stir the concrete. The holes 13 on the surface of the stirring rods 12 can draw air bubbles in the concrete into the stirring rods 12, thereby increasing the density and uniformity of the concrete and improving the concrete pouring effect. This avoids the arm pain caused by manually pouring buckets one by one, which reduces work efficiency and improves overall work efficiency.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
