Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind turbine tower technology, specifically to an enhanced wind turbine tower structure. Background Technology
[0002] Wind turbine towers are typically tens of meters high. As the capacity of the turbine increases, and in order to capture more wind energy, there is a trend towards larger rotor diameters, taller towers, and larger tower diameters. The tower diameter is much smaller than the tower height, making it a typical long and slender member. Long and slender members are prone to instability.
[0003] The specification of a partial reinforcement structure for a wind turbine tower (publication number CN203035462U) mentions "at least two circumferential load-reducing plates fixed to the inner wall of the tower; multiple longitudinal reinforcing beams fixed to the inner wall of the tower, with both ends of each longitudinal reinforcing beam fixed to the circumferential load-reducing plates; and several circumferential retainers, each circumferential retainer being fixedly connected to the multiple longitudinal reinforcing beams." However, the tower in the prior art is not wind-resistant or deformation-resistant, and has poor thermal insulation, making it difficult to maintain its durability. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, an enhanced wind turbine tower structure is provided to solve the problems that existing towers are not wind-resistant or deformation-resistant, have poor thermal insulation, and are not durable.
[0005] To achieve the above objectives, an enhanced wind turbine tower structure is provided, comprising an outer shell, a middle shell, and an inner reinforcing frame. The outer shell is constructed by welding together multiple sets of outer plates, and a first insulation layer is provided on the inner side of the outer plates. The middle shell is nested inside the outer shell, and the middle shell is constructed by welding together multiple sets of inner plates. A second insulation layer is provided on the outer side of the inner plates. Multiple sets of support columns are fixed between the middle shell and the outer shell, and an inner reinforcing frame is fixed on the inner side of the middle shell.
[0006] Furthermore, the first insulation layer is made of EPE pearl foam board, and multiple sets of first reinforcing ribs run vertically through the first insulation layer, with the lower part of the first reinforcing ribs inserted into the cement board surface laid on the ground.
[0007] Furthermore, an outer fixing plate is fixed to the outer side of the welded seam between the outer plates, and a base plate is provided at the bottom of the outer fixing plate, with screw holes provided on the base plate.
[0008] Furthermore, the second insulation layer is made of EPS insulation foam board, and multiple sets of second reinforcing ribs run vertically through the second insulation layer, with the lower part of the second reinforcing ribs inserted into the cement board surface laid on the ground.
[0009] Furthermore, both the outer and middle covers adopt an annular structure, and both the first and second insulation layers adopt an arc-shaped structure.
[0010] Furthermore, the inner reinforcement frame adopts a regular decagonal frame structure, and the inner reinforcement frame is composed of ten sets of anti-deformation pressure plates welded together, and a set of diagonal bracing rods are fixed between the middle of the inner side wall of each set of anti-deformation pressure plates and the ground.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. The outer surface of the outer casing of this utility model is provided with multiple sets of external fixing plates, which not only protect the welds between the outer plates, but also enhance the vertical deformation resistance of the outer casing. Simultaneously, the first insulation layer is provided for thermal insulation, making it safer and more durable.
[0013] 2. The outer and middle shells of this utility model constitute a double-shell structure for the wind turbine tower, which is not only more robust and sturdy, but also provides better thermal insulation, thus better protecting the equipment installed inside the tower.
[0014] 3. The inner reinforcing frame in this utility model is designed to enhance the deformation resistance of the inner wall of the inner casing and to improve wind resistance. This avoids the erosion caused by natural environmental factors when the wind-resistant structure is placed on the outside of the tower, resulting in a longer service life.
