Description

Technical Field

[0001] The invention relates to a concrete double-wind-wheel wind power tower structure, belonging to the technical field of wind power towers. Background Art

[0002] Against the backdrop of the global energy structure transformation and increasingly urgent environmental protection needs, wind power generation, with its significant advantages of clean, renewable and low-carbon emissions, is gradually becoming an important force to replace traditional fossil energy. However, current wind power generation technology still faces core problems such as low power generation efficiency, insufficient structural stability and high costs, and urgently needs technological innovation and breakthroughs.

[0003] Existing wind turbines usually adopt a single wind rotor structure, that is, one wind rotor is installed on a tower, which captures wind to drive the generator to rotate and generate electricity. However, this single wind rotor structure has limitations in the utilization of wind resources, especially in environments with low wind speeds or changing wind directions, its power generation efficiency will be greatly affected. In order to improve the efficiency and stability of wind power generation, the industry has begun to explore the design of a dual wind rotor structure, that is, installing two independent wind rotors on the same tower to achieve more efficient wind energy capture and utilization.

[0004] However, most of the existing double-rotor wind turbine tower structures are made of steel or composite materials, which are not only expensive, but also have strict requirements on terrain conditions. In addition, these structures also have certain technical difficulties and complexities in the design and manufacturing process. Therefore, it is particularly important to develop a new double-rotor wind turbine tower structure with low cost, stable structure and strong adaptability. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention proposes a concrete double-wind-rotor wind turbine tower structure with high wind energy utilization rate, low cost, good rigidity and stability, and simple assembly.

[0006] The technical solution of the present invention is: a concrete double-wind-wheel wind turbine tower structure, comprising a concrete tower, a cantilever beam, a long inclined cable, a short inclined cable and a foundation. The concrete tower is vertically fixed on the foundation, two cantilever beams are symmetrically fixed on the upper part of the concrete tower, and the long inclined cable and the short inclined cable are respectively fixedly connected between the cantilever beam and the top of the concrete tower.

[0007] Furthermore, the concrete tower and the cantilever beam are connected in an assembled manner.

[0008] Furthermore, the cross section of the concrete tower is square or quadrangular pyramid.

[0009] Due to the adoption of the above technical solution, the advantages of the present invention are: the present invention adopts concrete as the main material, which has the advantages of low cost, good durability, high stability, etc. At the same time, through ingenious design, the two wind wheels are reasonably installed on the same tower, realizing efficient capture and utilization of wind energy. In addition, the present invention simplifies the construction process by decomposing the tower into multiple modules that are easy to transport and install, reduces the dependence on large hoisting equipment, and improves construction efficiency.

[0014] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0015] Example

[0016] The schematic diagram of the concrete double wind turbine tower structure of the present invention is as follows: Figures 1 to 3 As shown, it includes a concrete tower 1, a cantilever beam 2, a long inclined cable 3, a short inclined cable 4 and a foundation 5. The concrete tower 1 is vertically fixedly installed on the foundation 5, two cantilever beams 2 are symmetrically fixedly installed on the upper part of the concrete tower 1, and the long inclined cable 3 and the short inclined cable 4 are fixedly connected between the cantilever beam 2 and the top of the concrete tower 1 respectively. Through the joint action of the long inclined cable 3 and the short inclined cable 4, the downward force on the cantilever beam 2 is reduced, and the overall bearing capacity of the structure is enhanced.

[0017] The concrete tower 1 and the cantilever beam 2 are connected in an assembled manner, which is convenient for transportation and installation. The cross section of the concrete tower 1 is square.

[0018] In summary, the present invention simplifies the construction process, reduces the reliance on large-scale lifting equipment, and improves construction efficiency by decomposing the tower into multiple modules that are easy to transport and install. This modular design not only shortens the construction period, but also reduces the amount of on-site work and the impact on the environment, which is in line with the current green and sustainable development concept.
