Description

Technical Field

[0001] The utility model relates to the technical field of wind power motors, in particular to a wind power tower steel strand diverter. Background Art

[0002] Wind turbines convert wind energy into mechanical energy. The wind rotor rotates under the action of wind force, which converts the kinetic energy of wind into the mechanical energy of the wind rotor shaft. The generator rotates and generates electricity under the drive of the wind rotor shaft. It is a green power generation equipment. Wind turbines are generally composed of impellers, wheel cabins, direction regulators, towers, speed limit safety mechanisms and energy storage devices.

[0003] Among them, the tower, also known as the tower pole or tower, mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the unit; the tower is generally made of metal or reinforced concrete, the purpose is to adapt to different working conditions and actual environments, but whether it is reinforced concrete or metal, it needs to be manufactured in sections during production, which is to facilitate transportation to the site for installation, because in most cases, transportation equipment cannot directly transport nearly 100 meters long towers. Therefore, during on-site installation, it is necessary to lift the tower sections one by one, so that they can be stacked and installed, and finally form a tower of full height. Since the formed tower needs to withstand wind forces from all directions and the vibration of the rotating impeller, in order to ensure that the tower does not fall, the engineers will set up multiple vertical steel strands inside the tower. The upper end of the steel strand is fixed to the top of the tower, and the lower end is fixed to the ground at the bottom of the tower, which is equivalent to providing a pulling force to pull the tower to prevent it from falling. However, some tower structures have diameters that gradually decrease from bottom to top. The tower of this structure presents a triangular structure, which makes the overall structure more stable. Since the internal steel strands are arranged vertically, the steel strands will be subjected to lateral forces when the tower is affected by wind. The steel strands are likely to fit and form friction with the inner wall of the tower, especially the part with a smaller diameter at the top of the tower. Under long-term friction, the steel strands and the inner wall of the tower will cause wear. Summary of the invention

[0004] The problem solved by the utility model is to provide a wind power tower steel strand diverter, which can arrange the steel strands vertically while effectively preventing the steel strands from fitting against the inner wall of the tower, thereby preventing the steel strands and the inner wall of the tower from wearing out.

[0005] In order to solve the above problems, the utility model provides a wind power tower steel strand diverter, including a tower body and a steel strand vertically arranged in the tower body, and also including an I-beam and a buffer sleeve; the I-beam is symmetrically provided with a first flange and a second flange; the first flange is fixed on the inner wall of the tower body; the buffer sleeve is wound around the outer peripheral wall of the steel strand, and the buffer sleeve is used to contact with the second flange.

[0006] Compared with the prior art, the present application has the following advantages: the structure of the I-beam can form a certain distance with the inner wall of the tower, and the lateral length of the I-beam is adjustable, which is convenient for arranging I-beams of different lateral lengths in tower members of different diameters so that the steel strands remain vertical, and the I-beams can effectively bear force. Since a buffer sleeve is wound around the circumference of the steel strand, it can contact the first buffer layer when lateral force is generated, thereby forming a certain protection for the steel strand and preventing wear of the steel strand and the inner wall of the tower.

[0007] In a possible implementation manner, a first buffer layer is further included. The first buffer layer is arranged on the outer surface of the second flange, and the first buffer layer is used to contact with the buffer sleeve.

[0008] Compared with the prior art, the first buffer layer using the above technical solution can provide further buffering protection for the I-beam and the buffer sleeve, preventing additional wear of the buffer sleeve and the I-beam, and further preventing wear of the steel strand.

[0009] In a possible implementation manner, a second buffer layer is further included, and the second buffer layer is arranged between the second flange and the first buffer layer.

[0010] Compared with the prior art, the above technical solution can achieve a better buffering effect and prevent the I-beam from being damaged.

[0011] In a possible implementation, a U-shaped fastener is further included, and a buffer plate for contacting with the first buffer layer is provided on the open side of the U-shaped fastener; and the enclosed area between the U-shaped fastener and the buffer plate is used for the steel strand to pass through.

[0012] Compared with the prior art, the enclosed area between the U-shaped fastener and the buffer plate of the above technical solution can tighten the steel strand, the buffer plate can interfere with the first buffer layer to make the buffering effect better, and the tightened steel strand is not easy to loosen, so it is not easy to generate additional friction.

[0013] In a possible implementation manner, a fastening plate for abutting against the buffer sleeve to form a tight fit is provided on a side of the buffer plate away from the first buffer layer.

[0014] Compared with the prior art, the above technical solution can further restrain the steel strands, making it less likely for the tightened steel strands to loosen and generate friction.

[0015] In a possible embodiment, fixed plates extending in a horizontal direction are fixed at both upper and lower ends of the second flange, the first buffer layer and the second buffer layer are arranged between the upper and lower fixed plates, and the sum of the thicknesses of the first buffer layer and the second buffer layer is greater than the extension length of the two fixed plates.

[0016] Compared with the prior art, the upper and lower fixed plates of the above technical solution allow the first buffer layer and the second buffer layer to form a limit when laying, which makes laying more convenient, and the sum of the thicknesses of the first buffer layer and the second buffer layer is greater than the extension length of the two fixed plates, so that the steel strands will not touch the fixed plates.

[0017] In a possible implementation manner, the first flange is fixed to the inner wall of the tower body by a first bolt member, and the second flange is fixed by a second bolt member that passes through the second buffer layer and the first buffer layer in sequence.

[0018] Compared with the prior art, the I-beam, the second buffer layer and the first buffer layer can be effectively fixed.

[0019] In a possible implementation manner, the end of the second bolt member is located in the first buffer layer.

[0020] Compared with the prior art, the second bolt does not pass through the first buffer layer, so that the first buffer layer and the buffer plate are in full contact. Otherwise, the second bolt will rub against the buffer plate, causing additional damage to the buffer plate and the second bolt itself.

[0021] In a possible implementation, the first buffer layer and the buffer sleeve are both made of rubber.

[0022] Compared with the prior art, the above technical solution can achieve better elasticity and effectively form a buffer.

[0023] In a possible implementation manner, the second buffer layer and the buffer plate are both polytetrafluoroethylene plates; and the fastening plate is a steel plate.

[0024] Compared with the prior art, the polytetrafluoroethylene plate using the above technical solution has good anti-aging endurance, has rigidity and certain toughness, and can effectively buffer; the steel plate can effectively form a tight fit with the steel strand.

Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0031] In the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0032] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] In some embodiments, a wind turbine tower steel strand diverter is provided, comprising a tower body 1 and a steel strand 100 vertically arranged in the tower body 1, and also comprising an I-beam 2 and a buffer sleeve 101; a first flange 21 and a second flange 22 are symmetrically arranged on the I-beam 2; the first flange 21 is fixed on the inner wall of the tower body 1; the buffer sleeve 101 is wound around the outer peripheral wall of the steel strand 100, and is used to contact the second flange 22.

[0034] In the present embodiment, the I-beam 2 itself is composed of two symmetrically arranged flanges and a middle web, so the first flange 21 and the second flange 22 arranged on the I-beam 2 belong to the prior art and are not described in detail. In the present utility model, the I-beam 2 is not a whole piece, but is formed by cutting a piece from the whole I-beam. The length of the middle web of the I-beam 2 can be flexibly adjusted according to the diameter of different tower components. For example, in tower components with smaller diameters, the web can be adjusted to be longer, and vice versa. This can ensure that the steel strand 100 is vertical as a whole in the tower, and the I-beam 2 can be effectively stressed. Since a buffer sleeve 101 is wound around the circumference of the steel strand 100, it can contact the first buffer layer 3 when a lateral force is generated, thereby forming a certain protection for the steel strand 100 and preventing the steel strand 100 from being worn.

[0035] In some embodiments, a first buffer layer 3 is further included, which is disposed on the outer surface of the second flange 22 and is used to contact the buffer sleeve 101. The first buffer layer 3 can further buffer and protect the I-beam 2 and the buffer sleeve 101, preventing additional wear of the buffer sleeve 101 and the I-beam 2, thereby preventing wear of the steel strand 100.

[0036] In some embodiments, a second buffer layer 4 is further included, and the second buffer layer 4 is disposed between the second flange 22 and the first buffer layer 3. The second buffer layer 4 can provide better buffering and prevent the I-beam 2 from being damaged.

[0037] In some embodiments, a U-shaped fastener 5 is further included, and a buffer plate 51 for contacting the first buffer layer 3 is provided on the open side of the U-shaped fastener 5; the enclosed area between the U-shaped fastener 5 and the buffer plate 51 is used for the steel strand 100 to pass through.

[0038] In this embodiment, the enclosed area between the U-shaped fastener 5 and the buffer plate 51 can effectively tighten the steel strand 100 to prevent loosening and causing additional friction. The U-shaped fastener 5 adopts a U-bolt. By inserting the buffer plate 51 into the open end of the U-bolt, the buffer plate 51 can clamp the steel strand 100, so that the steel strand 100 is not prone to excessive friction with the inner wall of the U-shaped fastener 5, which may cause excessive wear of the steel strand 100 and the U-shaped fastener 5. The open end of the U-bolt can pass through the second buffer layer 4 and the first buffer layer 3 in turn for fixation. The first buffer layer 3 and the second buffer layer 4 can buffer the I-beam 2 itself to prevent the I-beam 2 from being damaged by excessive force.

[0039] In some embodiments, a fastening plate 52 is provided on one side of the buffer plate 51 away from the first buffer layer 3 for a tight fit with the buffer sleeve 101. The steel strand 100 can be further restrained, making the steel strand 100 less likely to loosen and less likely to generate friction.

[0040] In some embodiments, fixed plates 221 extending in a horizontal direction are fixed at the upper and lower ends of the second flange 22, the first buffer layer 3 and the second buffer layer 4 are arranged between the upper and lower fixed plates 221, and the sum of the thicknesses of the first buffer layer 3 and the second buffer layer 4 is greater than the extension length of the two fixed plates 221.

[0041] In this embodiment, as shown in the attached Figure 1 As shown, the upper and lower fixing plates 221 allow the first buffer layer 3 and the second buffer layer 4 to form a limit when laying, which makes the laying more convenient, and the sum of the thickness of the first buffer layer 3 and the second buffer layer 4 is greater than the extension length of the two fixing plates 221, and the end of the fixing plate 221 close to the steel strand 100 will not touch the steel strand 100.

[0042] In some embodiments, the first flange 21 is fixed to the inner wall of the tower body 1 by a first bolt member 6 , and the second flange 22 is fixed by a second bolt member 7 that passes through the second buffer layer 4 and the first buffer layer 3 in sequence.

[0043] In this embodiment, as shown in the attached Figure 1 As shown, the upper and lower sides of the first flange 21 are fixed to the side wall of the tower body 1 by the first bolt member 6, and the upper and lower sides of the second flange 22 are fixed by the second bolt member 7 that passes through the first buffer layer 3 and the second buffer layer 4 in sequence, so that the I-beam 2, the second buffer layer 4 and the first buffer layer 3 can be effectively fixed.

[0044] In some embodiments, the end of the second bolt member 7 is located in the first buffer layer 3 .

[0045] In this embodiment, as shown in the attached Figure 1 As shown, the second bolt member does not penetrate the first buffer layer 3, so that the first buffer layer 3 and the buffer plate 51 are in full contact, otherwise the second bolt member 7 will contact and rub against the buffer plate 51, causing additional damage to the buffer plate 51, and also causing additional damage to the second bolt member 7 itself

[0046] In some embodiments, the second buffer layer 4 and the buffer sleeve 101 are both made of rubber, which has good elasticity and can effectively form a buffer.

[0047] In some embodiments, the first buffer layer 3 and the buffer plate 51 are both polytetrafluoroethylene plates; the fastening plate 52 is a steel plate. The polytetrafluoroethylene plate has good anti-aging resistance, is rigid and has a certain toughness, and can effectively buffer; the rigidity of the steel plate can effectively form a tight fit with the buffer sleeve 101, and is not easy to deform when subjected to strong extrusion.
