Description

Technical Field

[0001] This invention relates to the field of wind turbine technology, and in particular to a novel wind turbine tower that facilitates heat dissipation. Background Technology

[0002] In wind turbines, to ensure effective heat dissipation, natural convection is created through ventilation openings at the top and bottom of the tower, utilizing the thermal pressure effect (hot air rises, cold air flows in). This avoids the problem of poor internal air circulation and heat accumulation.

[0003] The climbing ladder inside the wind turbine tower is a key passage for maintenance personnel to go up and down the tower. In the existing technology, the top of the climbing ladder does not extend directly to the inside of the wind turbine body. Instead, an additional connecting ladder is installed on the lower surface of the wind turbine body to prevent interference between the ladder and the wind turbine during subsequent hoisting. However, there is a distance between the two ladders, which is inconvenient for subsequent climbing.

[0004] In addition, when the tower and the wind turbine body are connected, the wind turbine body is transported by hoisting. Due to the large overturning moment generated by the blades of the wind turbine body, there is a problem of large gaps at the connection point during the connection, which brings inconvenience to the subsequent bolting and welding reinforcement. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by proposing a novel wind turbine tower that facilitates heat dissipation.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a novel wind turbine tower body for easy heat dissipation, comprising a tower cylinder, a lower ventilation opening at the lower end of the side surface of the tower cylinder, a wind turbine body inserted into the upper end of the tower cylinder, an upper ventilation opening at the lower surface of the wind turbine body, a connecting ladder fixedly installed inside the upper ventilation opening, a climbing ladder fixedly installed inside the tower cylinder, an inclined ladder fixedly connected to the lower end of the connecting ladder, limit blocks fixedly connected to the lower ends of the two sides of the inclined ladder, and concave blocks connected to the upper ends of the two sides of the climbing ladder through longitudinal elastic mechanisms, with a vertical elastic mechanism provided on the lower surface of the concave blocks;

[0007] After the limiting block is engaged inside the concave block, the vertical elastic mechanism applies a downward force to the concave block.

[0008] Preferably, the longitudinal elastic mechanism includes a guide plate fixedly connected to the upper end of the side surface of the climbing ladder, a concave block movably connected to the upper surface of the guide plate, a vertical connecting plate fixedly connected to the rear end of the guide plate, a first T-shaped column fixedly connected to the rear surface of the concave block, a first compression spring sleeved on the outer surface of the first T-shaped column, a vertical opening penetrating the front surface of the vertical connecting plate, the first T-shaped column slidingly passing through the inner side of the vertical opening, and the first compression spring located on the front surface of the vertical connecting plate.

[0009] Preferably, the upper surface of the guide plate has a through-hole, and the lower surface of the concave block is fixedly connected to a slider. The slider slides through the inner side of the through-hole, and the two sides of the slider are respectively provided with movable grooves. The height of the movable grooves is greater than the thickness of the guide plate.

[0010] Preferably, the vertical elastic mechanism includes a platform fixedly connected to the side surface of the climbing ladder and near the bottom of the guide plate. The upper surface of the platform has a through-hole. A second T-shaped column is fixedly connected to the lower surface of the slider. The second T-shaped column slides through the inside of the through-hole. A second compression spring is sleeved on the outer surface of the second T-shaped column. The second compression spring is located on the lower surface of the platform. A limiting plate is fixedly sleeved on the outer surface of the second T-shaped column and near the top of the platform. A locking mechanism is provided at the rear end of the upper surface of the platform. A locking seat is fitted at the front of the locking mechanism. A locking slot is provided at the front of the outer surface of the locking seat.

[0011] Preferably, the lower surface of the limiting plate has side openings on both sides, and the upper surface of the card holder has protruding edges fixedly connected to both sides.

[0012] Preferably, the locking mechanism includes a bending seat fixedly connected to the upper surface of the platform, a third T-shaped post slidingly passing through the upper surface of the bending seat, a hook block fixedly connected to the lower end of the third T-shaped post, a third compression spring sleeved on the outer surface of the third T-shaped post, the third compression spring being located between the inner top surface of the bending seat and the upper surface of the hook block, a bent edge fixedly connected to the rear side of the locking seat, an inclined guide surface being provided on the front surface of the hook block, and the lower side of the hook block being engaged with the inner side of the bent edge.

[0013] Preferably, the lower surface of the limiting block is provided with a pressing surface, and the upper surface of the concave block is provided with a pushing surface.

[0014] Preferably, a plug is fixedly connected to the lower surface of the wind turbine body and the outer end near the lower ventilation opening, and a mating interface is provided at the upper port of the tower. The plug is slidably inserted into the inner side of the mating interface, and the connecting ladder passes through the inner side of the plug.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the hoisting process, after the concave block is reset, the lower part of the limiting plate is no longer limited by the card seat. At the same time, due to the existence of the movable groove, the concave block can move down as much as possible under the elastic force of the second compression spring, ensuring that the concave block presses down the limiting block as much as possible, thereby ensuring the tightness and stability of the connection between the tower and the wind turbine body, so as to facilitate the subsequent bolt reinforcement and welding operations at the connection, and ensure the stability of the connection.

[0017] 2. In this invention, after the wind turbine body and tower are hoisted, the lower end of the inclined ladder is connected to the climbing ladder, and the upper end of the inclined ladder is integrated with the connecting ladder. Therefore, during later maintenance, workers can directly enter the inside of the wind turbine body by following the climbing ladder, inclined ladder and connecting ladder, which brings convenience to maintenance.

[0028] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0029] like Figures 1-9 The above describes a novel wind turbine tower body designed for easy heat dissipation, comprising a tower 1, a lower ventilation opening 3 at the lower end of the side surface of the tower 1, a wind turbine body 2 inserted into the upper end of the tower 1, an upper ventilation opening 6 at the lower surface of the wind turbine body 2, a connecting ladder 7 fixedly installed inside the upper ventilation opening 6, a climbing ladder 9 fixedly installed inside the tower 1, an inclined ladder 8 fixedly connected to the lower end of the connecting ladder 7, limit blocks 10 fixedly connected to the lower ends of the two sides of the inclined ladder 8, and concave blocks 12 connected to the upper ends of the two sides of the climbing ladder 9 via longitudinal elastic mechanisms, with a vertical elastic mechanism provided on the lower surface of the concave blocks 12.

[0030] After the limiting block 10 is engaged inside the concave block 12, the vertical elastic mechanism applies a downward force to the concave block 12.

[0031] like Figure 4 , Figure 5 , Figure 7 As shown, the longitudinal elastic mechanism includes a guide plate 14 fixedly connected to the upper end of the side surface of the climbing ladder 9. A concave block 12 is movably connected to the upper surface of the guide plate 14. A vertical connecting plate 15 is fixedly connected to the rear end of the guide plate 14. A first T-shaped post 20 is fixedly connected to the rear surface of the concave block 12. A first compression spring 21 is sleeved on the outer surface of the first T-shaped post 20. A vertical opening 17 is provided through the front surface of the vertical connecting plate 15. The first T-shaped post 20 slides through the inner side of the vertical opening 17. The first compression spring 21 is located on the front surface of the vertical connecting plate 15. Due to the presence of the vertical opening 17, the first T-shaped post 20 can slide down relative to the inner side of the vertical opening 17, ensuring that the inner top surface of the concave block 12 can be pressed against the upper surface of the limiting block 10.

[0032] A sliding opening 16 is formed through the upper surface of the guide plate 14. A slider 18 is fixedly connected to the lower surface of the concave block 12. The slider 18 slides through the inner side of the sliding opening 16. Movable grooves 19 are formed on both sides of the slider 18. The height of the movable grooves 19 is greater than the thickness of the guide plate 14. The design of the movable grooves 19 ensures that the slider 18 can slide along the inner side of the sliding opening 16 and can also move downward relative to the sliding opening 16.

[0033] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the vertical elastic mechanism includes a platform 22 fixedly connected to the side surface of the climbing ladder 9 and near the bottom of the guide plate 14. A hollow opening 23 is provided through the upper surface of the platform 22. A second T-shaped column 24 is fixedly connected to the lower surface of the slider 18. The second T-shaped column 24 slides through the inside of the hollow opening 23. A second compression spring 25 is sleeved on the outer surface of the second T-shaped column 24. The second compression spring 25 is located on the lower surface of the platform 22. A limiting plate 26 is fixedly sleeved on the outer surface of the second T-shaped column 24 and near the top of the platform 22. A locking mechanism is provided at the rear end of the upper surface of the platform 22. A locking seat 28 is locked at the front of the locking mechanism. A locking slot 30 is provided at the front of the outer surface of the locking seat 28. It should be noted that this part indicates the position of the card holder 28 after hoisting is completed. At this time, the card holder 28 is not located on the lower surface of the limiting plate 26. Therefore, under the elastic force of the second compression spring 25, the slider 18, concave block 12 and other structures are driven to move down, thereby ensuring that the limiting block 10 is pressed.

[0034] The lower surface of the limiting plate 26 has side openings 27 on both sides, and the upper surface of the mounting base 28 has protruding edges 29 fixedly connected to both sides. This ensures that during the hoisting of the wind turbine body 2, when the concave block 12 and the second T-shaped column 24 move backward, the mounting base 28 moves backward synchronously, and the mounting base 28 will not rotate relative to the limiting plate 26. Figure 8 , Figure 9 As shown, the positional relationship between the mounting bracket 28 and the limiting plate 26 during hoisting is illustrated. At this time, the protruding edge 29 is inserted into the inside of the side opening 27, thereby preventing the mounting bracket 28 from rotating relative to the limiting plate 26.

[0035] like Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the positioning mechanism includes a bent seat 31 fixedly connected to the upper surface of the platform 22. A third T-shaped column 32 slides through the upper surface of the bent seat 31. A hook block 34 is fixedly connected to the lower end of the third T-shaped column 32. A third compression spring 33 is sleeved on the outer surface of the third T-shaped column 32. The third compression spring 33 is located between the inner top surface of the bent seat 31 and the upper surface of the hook block 34. A bent edge 36 is fixedly connected to the rear side of the positioning seat 28. An inclined guide surface 35 is opened on the front surface of the hook block 34. The lower side of the hook block 34 is inserted into the inner side of the bent edge 36. This state is such that after the hoisting is completed, the bent edge 36 is limited by the hook block 34, thereby fixing the position of the positioning seat 28.

[0036] like Figure 4 , Figure 5 As shown, the lower surface of the limiting block 10 has a pressing surface 11, and the upper surface of the concave block 12 has a pushing surface 13. During hoisting, the state is as follows... Figure 8 , Figure 9 As shown, when the pressing surface 11 and the pushing surface 13 come into contact and engage, the concave block 12 can be pushed and moved more smoothly toward the rear.

[0037] like Figure 2 , Figure 3 As shown, a plug 4 is fixedly connected to the lower surface of the wind turbine body 2 and near the outer end of the lower ventilation opening 3. A mating interface 5 is provided at the upper port of the tower 1. The plug 4 is slidably inserted into the inner side of the mating interface 5, and the connecting ladder 7 passes through the inner side of the plug 4. This is a common docking method between the wind turbine body 2 and the tower 1, and will not be described in detail.

[0038] During the hoisting process, after the tower 1 is installed, the wind turbine body 2 is connected. The insert 4 is aligned with the interface 5 to complete the connection. During this process, the inclined ladder 8 enters the inner side of the tower 1, as... Figure 8 , Figure 9 As shown, when the limiting block 10 reaches the upper surface of the concave block 12, the pushing surface 13 and the pressing surface 11 come into contact with each other, causing the concave block 12 to move backward and compress the first compression spring 21. The slider 18, the second T-shaped post 24, the limiting plate 26, and the card holder 28 will move backward synchronously. The second T-shaped post 24 moves backward along the inner side of the cutout 23. Since the rear end of the card slot 30 is closed, the card holder 28 moves backward synchronously with the second T-shaped post 24. After the rear edge of the bent edge 36 contacts the inclined guide surface 35, This causes the hook block 34 to be pushed upward, compressing the third compression spring 33. After ensuring that the hook block 34 can be inserted into the bent edge 36, the limiting block 10 moves downward to the inner side of the concave block 12. Under the elastic force of the first compression spring 21, the concave block 12 moves forward and resets, inserting the limiting block 10 into the inner side of the concave block 12. At the same time, the limiting plate 26 separates from the card seat 28, and the second T-shaped post 24 slides out from the front end of the card slot 30, while keeping the position of the card seat 28 fixed. Figure 4 , Figure 5 , Figure 6 As shown, after the concave block 12 is reset, since the lower part of the limiting plate 26 is no longer limited by the card seat 28, and due to the presence of the movable groove 19, the concave block 12 can move down as much as possible under the elastic force of the second compression spring 25, ensuring that the concave block 12 presses down the limiting block 10 as much as possible, thereby ensuring the tightness and stability of the connection between the tower 1 and the wind turbine body 2, so as to facilitate the subsequent bolt reinforcement and welding operations at the connection point and ensure the stability of the connection.

[0039] After the wind turbine body 2 and tower 1 are hoisted, the lower end of the inclined ladder 8 is connected to the climbing ladder 9. At the same time, the upper end of the inclined ladder 8 is integrated with the connecting ladder 7. Therefore, during later maintenance, workers can directly enter the inside of the wind turbine body 2 by following the climbing ladder 9, the inclined ladder 8 and the connecting ladder 7, which brings convenience to maintenance.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
