Technical Field

[0001] The utility model belongs to the technical field of tower platforms, in particular to a tower platform sealing structure. Background Art

[0002] The tower used for wind power generation is equipped with a platform at the bottom of the tower. The platform is usually several meters high. The control system of the wind turbine generator set, such as the electrical control cabinet, is placed on the platform. When installing the tower, the platform and the platform bracket need to be installed on the foundation, and then the control system and related equipment are set on the platform. The tower is then hoisted onto the platform bracket for installation. Since shaking is inevitable during hoisting, in order to reduce the difficulty of installation, the outer diameter of the platform is generally smaller than the inner diameter of the first tower section. Such a setting will create a gap between the inner wall of the tower and the platform.

Example

[0021] Reference Figure 1-Figure 4 A tower platform sealing structure includes a tower 1 and a platform bracket 2 arranged on the lower surface of the tower 1. The outer surface of the bottom end of the tower 1 is fixedly connected with an annular extension plate 13. The upper surface of the annular extension plate 13 is provided with a through hole 14. The upper surface of the platform bracket 2 near the platform 3 is provided with a positioning rod 15. The number of the positioning rods 15 is several, and the several positioning rods 15 are equidistantly arranged on the upper surface of the tower 1 along the circumferential direction. The positioning rods 15 pass through the through hole 14 and are threadedly connected with nuts 16. The lower surface of the tower 1 is fixedly connected There is a positioning plate 11, and a positioning slot 12 is opened on the upper surface of the tower 1 between the platform 3 and the positioning rod 15. The outer surface of the positioning plate 11 is plugged into the inner surface of the positioning slot 12. Specifically, when the tower 1 is lifted and placed on the platform bracket 2 by using a lifting device, the through hole 14 is passed through the positioning rod 15 and then placed on the upper surface of the platform bracket 2, and the positioning plate 11 is engaged with the positioning slot 12, and then a nut 16 is threadedly connected on the upper surface of the positioning rod 15 to fix the tower 1 and the platform bracket 2.

[0022] Reference Figure 1-Figure 4 A platform 3 is fixedly connected to the middle part of the upper surface of the platform bracket 2, and a control cabinet assembly 17 is installed in the middle part of the upper surface of the platform 3. A plurality of grooves 4 are opened on the outer surface of the platform 3, and a spring 5 is fixedly connected to the inner wall of the groove 4. The end of the spring 5 away from the inner wall of the groove 4 is fixedly connected to a support plate 6, and the end of the support plate 6 away from the spring 5 is fixedly connected to an arc plate 7, and an arc rubber pad 8 is bonded to the side of the arc plate 7 away from the support plate 6. There are several arc rubber pads 8, and several arc rubber pads 8 are circumferentially arranged on the inner wall of the tower 1, and the end faces of two adjacent arc rubber pads 8 are abutted against each other. Specifically, when the inner wall of the bottom end of the tower 1 is sleeved on the outer side surface of the platform 3, the elastic potential energy of the spring 5 will elastically support the arc plate 7 and the arc rubber pad 8 through the support plate 6, thereby buffering the shaking of the tower 1.

[0023] Reference Figure 1-Figure 4The side of the arc-shaped rubber pad 8 away from the arc plate 7 is against the inner wall of the tower 1, and the outer surface of the support plate 6 is bonded with a buffer pad 10. Specifically, the buffer pad 10 can enhance the friction between the support plate 6 and the inner wall of the groove 4, thereby improving the buffering effect; a deformation hole 9 is opened inside the arc-shaped rubber pad 8. Specifically, the deformation hole 9 arranged inside the arc-shaped rubber pad 8 can provide a deformation space for the deformation of the arc-shaped rubber pad 8. When the arc-shaped rubber pad 8 is subjected to the shaking and squeezing of the tower 1, it can not only improve the sealing of the connection between the arc-shaped rubber pad 8 and the inner wall of the tower 1, but also reduce the shaking amplitude of the tower 1. Through the cooperation of the above structure, when the tower 1 is installed, the sealing between the inner wall of the tower 1 and the platform 3 can be enhanced, the shaking amplitude of the tower 1 can be reduced, and the stability of the installation can be improved.

[0024] The implementation principle of a tower platform sealing structure embodiment of the present application is:

[0025] When the tower 1 is lifted and placed on the platform bracket 2 by using the lifting equipment, the through hole 14 is passed through the positioning rod 15 and placed on the upper surface of the platform bracket 2, and the positioning plate 11 is engaged with the positioning slot 12, and then the nut 16 is threadedly connected on the upper surface of the positioning rod 15 to fix the tower 1 and the platform bracket 2.

[0026] When the inner wall of the bottom end of the tower 1 is sleeved on the outer side of the platform 3, the elastic potential energy of the spring 5 will elastically support the arc plate 7 and the arc rubber pad 8 through the support plate 6, thereby buffering the shaking of the tower 1, and the buffer pad 10 can enhance the friction between the support plate 6 and the inner wall of the groove 4, thereby improving the buffering effect; at the same time, the deformation hole 9 arranged inside the arc rubber pad 8 can provide a deformation space for the deformation of the arc rubber pad 8. When the arc rubber pad 8 is squeezed by the shaking of the tower 1, it can not only improve the sealing of the connection between the arc rubber pad 8 and the inner wall of the tower 1, but also reduce the shaking amplitude of the tower 1; through the cooperation of the above structure, when the tower 1 is installed, the sealing between the inner wall of the tower 1 and the platform 3 can be enhanced, the shaking amplitude of the tower 1 can be reduced, and the stability of the installation can be improved.
