Description

Technical Field

[0001] The utility model relates to the technical field of tower platforms of wind turbine generator sets, in particular to a tower barrel platform cover for tower installation. Background Art

[0002] Currently, most wind turbines have been installed with a climbing aid, which allows on-site workers to avoid the time-consuming and labor-intensive climbing process. However, when using the climbing aid to board the machine, it is extremely inconvenient to complete the cover closing operation after passing the tower platform cover. Similarly, once the cover is closed, it is extremely inconvenient to open it again when the climbing aid descends. In addition, after the workers pass the platform, the maintenance personnel need to raise the climbing aid to a certain height before closing the cover. To close the cover, the maintenance personnel on the climbing aid have to remove the anti-fall protection device and climb down the climbing aid to close the cover by hand. Therefore, for the convenience of use, many wind farms usually keep the cover in an open state for a long time, but do not close the tower platform cover, which poses a major safety hazard and affects work efficiency.

[0003] In response to the above issue, the existing patent publication number CN217002169U, entitled "Automatic Closing Device for the Tower Platform Cover of a Wind Turbine Generator Set", proposes a solution. This utility model arranges a first sensor and a second sensor on the ladder. When workers or equipment pass through the sensors, the cover on the tower will automatically open and close, thereby improving the work efficiency of workers and reducing safety hazards. It can be widely promoted.

[0004] However, when the cylinder platform cover disclosed in the appealed patent is used, the cover is automatically opened and closed through technologies such as sensors. However, if electronic equipment such as sensors fail, the cover cannot be automatically opened and closed, which will bring great safety hazards. Therefore, it is necessary to propose a tower cylinder platform cover for tower installation to solve the above problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The utility model provides Figure 1-Figure 5 The tower body platform cover for tower installation shown includes a tower platform 1, a cover 2 is provided on the tower platform 1, a ladder 3 fixedly connected to the tower platform 1 is provided at the end of the cover 2, and a cover plate 6 is provided on the cover 2 through a closing component.

[0028] Furthermore, the closing component includes two movable grooves 8 fixedly arranged inside the tower platform 1, the two movable grooves 8 are located on the same side of the cover 2, and the two movable grooves 8 are symmetrically distributed about the center line of the cover 2, and a support shaft 10 is fixedly connected between the middle parts of the inner walls on both sides of the movable groove 8, and a push rod 9 is rotatably arranged at the outer ring of the support shaft 10. The push rod 9 is adapted to the movable groove 8, and the push rod 9 at the front end extends downward, and the push rod 9 at the rear end extends upward. The push rod 9 and the cover plate 6 are connected to each other through a connecting component.

[0029] Furthermore, the connecting assembly includes a base 4 fixedly set on the tower platform 1, and there are two bases 4, which are symmetrically distributed about the center line of the cover 2. A rotating shaft 5 is rotatably set between the two bases 4, and a connecting plate 7 is fixedly set at the outer ring of the rotating shaft 5. The cover plate 6 and the rotating shaft 5 are fixedly connected, and the cover plate 6 and the connecting plate 7 are on the same plane. A second connecting seat 12 is fixedly set at one end of the side of the connecting plate 7, and a first connecting seat 11 is fixedly set on the side of the end of the push rod 9. A steering rod 13 is rotatably set between the second connecting seat 12 and the first connecting seat 11.

[0030] When using the tower cylinder platform cover for tower installation, in the initial state, the cover plate 6 covers the cover opening 2. When the staff climbs on the ladder 3, after climbing to the position of the cover plate 6, they push the push rod 9 at the front end counterclockwise by hand, so that the push rod 9 rotates a certain angle around the support shaft 10, and then drives the connecting plate 7, the rotating shaft 5 and the cover plate 6 to rotate clockwise around the central axis of the rotating shaft 5 through the steering linkage of the steering rod 13, thereby opening the cover plate 6.

[0031] When the staff passes through the cover 2, they push the push rod 9 at the rear end clockwise with their feet. Similarly, the connecting plate 7, the rotating shaft 5 and the cover 6 are driven to rotate counterclockwise around the central axis of the rotating shaft 5, thereby closing the cover 6.

[0032] The above is an operation when climbing up from the bottom. In addition to the above method, the traditional method of directly opening and closing the cover plate 6 manually can also be adopted, that is, pushing the cover plate 6 open with hands and closing the cover plate 6 with feet.

[0033] When climbing from top to bottom, after climbing to the position of the cover plate 6, use your feet to push the push rod 9 at the rear end counterclockwise to drive the cover plate 6 to open. After passing through the cover opening 2, use your hands to push the push rod 9 at the front end clockwise to drive the cover plate 6 to close.

[0034] In summary, when the new device is in use, the staff does not need to come down from the ladder 3 to complete the opening or closing operation of the cover 6, which improves the practicality of the device. Through this mechanical opening and closing method, the problem of the existing wind turbine tower barrel platform cover using sensors and other technologies to achieve automatic opening and closing of the cover 6 is solved. However, if the electronic equipment such as the sensor fails, the cover 6 cannot be automatically opened and closed, which will bring greater safety hazards.

[0035] In order to ensure that 6 can be stable after opening, a vertical pole 14 is fixedly provided on the top of the tower platform 1. The vertical pole 14 is located in the middle of the side of the cover 2 and between the two movable grooves 8. A first magnet 15 is fixedly provided on the side of the top of the vertical pole 14, and a second magnet 16 is fixedly provided on the end of the top of the cover 6. When the cover 6 is opened, the second magnet 16 and the first magnet 15 are magnetically attracted to each other, thereby facilitating the fixing of the cover 6 and facilitating the closing of the cover 6, thereby improving the practicality of the device.

[0036] In order to support 6, support plates 18 fixed on the tower platform 1 are provided on both sides of the cover 2. When the cover 6 is closed, the cover 6 and the support plates 18 fit together and support the cover 6 through the support plates 18.

[0037] Furthermore, a limit plate 17 is fixedly provided at the end of the bottom of the cover plate 6. Through the installation of the limit plate 17, when a heavy object falls and hits the cover plate 6, the middle part of the cover plate 6 is bent and deformed. At this time, the limit plate 17 and the support plate 18 are engaged with each other to avoid the cover plate 6 from breaking completely, which would cause the heavy object to continue to fall, thereby improving the practicality of the device.

[0038] Furthermore, a buffer pad 19 is provided on the top of the support plate 18. When the cover 6 is closed, the cover 6 and the buffer pad 19 fit together. By installing the buffer pad 19, the vibration when the cover 6 is closed is alleviated, the noise is reduced, and the problem of wear of the cover 6 is avoided.

[0039] In order to further reduce the shock when the cover 6 is closed, a number of evenly distributed telescopic rods 20 are provided inside the buffer pad 19, and a number of telescopic slots 21 corresponding to the telescopic rods 20 are provided inside the support plate 18. A spring 22 is fixedly connected between one end of the telescopic rod 20 that is movably extended into the telescopic slot 21 and the end of the telescopic slot 21. The telescopic rod 20 is driven to move downward through the cover 6, so that the spring 22 is compressed, thereby further weakening the vibration when the cover 6 is closed, thereby improving the practicality of the device.
