Description

Technical Field

[0001] The utility model belongs to the technical field of wind turbine towers, and particularly relates to a waterproof cover and a waterproof structure for a mixed tower. Background Technique

[0002] Wind power generation is a renewable energy technology that converts wind energy into electrical energy. Therefore, it is renewable. Compared with limited non-renewable energy sources such as coal and natural gas, wind power generation can continuously provide electricity and will not cause permanent damage to the environment. At the same time, wind power generation does not produce greenhouse gases such as carbon dioxide and other pollutants during the power generation process. Therefore, it has extremely high environmental protection. Compared with fossil fuel power generation, wind power generation significantly reduces the risks of air pollution and global climate change, and is of great significance for improving environmental quality and protecting the earth's ecosystem.

[0003] The basic principle of wind power generation is that the kinetic energy of the wind is converted into mechanical energy through a wind turbine, and then drives a generator to generate electricity and convert it into electrical energy. Specifically, a wind turbine drives the windmill blades to rotate through the wind, and then the rotating speed is increased through a speed increaser to make the generator generate electricity. The wind power generation tower is the main load-bearing component of the wind power generation unit.

[0004] In the existing mixed tower of a wind power generation unit, the lower part is a concrete tower, and the upper part is a steel tower. The concrete section usually adopts a prestressed concrete structure to enhance its load-bearing capacity and stability. The steel tower section is made of steel and has the advantages of light weight, high strength, easy processing and installation.

[0005] However, there is an exposed platform at the connection between the concrete tower and the steel tower. Rainwater is likely to converge on this platform, increasing the risk of water leakage at the connection between the concrete tower and the steel tower. After water leakage at this connection, the rainwater will drip onto the equipment below inside the tower, increasing the risk of equipment short circuit. Therefore, a waterproof structure needs to be designed to solve this problem. Summary of the Invention

[0006] The utility model provides a waterproof cover and a waterproof structure for a mixed tower, reducing the risk of water seepage and dripping at the connection between the concrete tower and the steel tower.

[0007] To achieve the above object, a waterproof cover of the utility model includes a plurality of waterproof members fixedly connected end to end in sequence. The waterproof member includes a waterproof housing, and the waterproof housing includes a first waterproof surface, a second waterproof surface, a third waterproof surface, a fourth waterproof surface and a fifth waterproof surface fixedly connected in sequence; the first waterproof surface and the fifth waterproof surface are coaxially arranged, and the second waterproof surface and the fourth waterproof surface are inclined.

[0008] Furthermore, the waterproof housings are connected in a detachable manner.

[0009] Furthermore, connecting plates are provided at both ends of the waterproof housing, and two adjacent waterproof housings are fixedly connected through the connecting plates and fasteners.

[0010] Furthermore, the inclination angle of the fourth waterproof surface is greater than that of the second waterproof surface.

[0011] Furthermore, the waterproof cover is made of stainless steel.

[0012] Furthermore, the outside of the waterproof cover is hot-dip galvanized.

[0013] A waterproof structure for a mixed tower, the mixed tower includes an upper tower barrel and a lower tower barrel, and is characterized in that it includes the above-mentioned waterproof cover. The first waterproof surface is externally connected to the upper tower barrel, the fifth waterproof surface is externally connected to the lower tower barrel, and the first waterproof surface and the outer peripheral surface of the upper tower barrel are sealed with sealant.

[0014] Furthermore, the first waterproof surface is fixedly connected to the upper tower barrel through support columns, and a plurality of the support columns are fixed on the outer wall of the upper tower barrel.

[0015] Furthermore, a waterproof part is provided at the connection gap between the upper tower barrel and the lower tower barrel, and the waterproof part is made of waterproof material.

[0016] Furthermore, the fifth waterproof surface is connected to the lower tower barrel through fasteners, and the fasteners abut against the outer peripheral surface of the lower tower barrel.

[0017] Compared with the prior art, the present utility model has at least the following beneficial technical effects:

[0018] In the present utility model, a waterproof cover is provided at the connection between the concrete tower barrel and the steel tower barrel. The upper and lower parts of the waterproof cover are externally connected to the outer peripheral surfaces of the upper tower barrel and the lower tower barrel respectively, and sealant is applied between the fitting surfaces of the upper part of the waterproof cover and the upper tower barrel, which can effectively guide rainwater to flow outside the tower barrel and reduce the risk of water leakage at the connection between the concrete tower barrel and the steel tower barrel.

[0019] A waterproof cover provided by the present utility model is in the shape of a hollow frustum of a cone. The water falling or depositing on the waterproof cover slides down through the inclined surface to prevent water accumulation. At the same time, the waterproof cover has two-stage inclined surfaces, which makes the structure of the rainproof cover more stable, enhances the wind pressure resistance ability, and improves the stability of the overall structure.

[0020] Furthermore, the outside of the waterproof cover is hot-dip galvanized. The zinc layer can effectively block the contact between air and water, thereby reducing the oxidation and corrosion of the steel surface, improving the corrosion resistance of the steel, extending the service life, and at the same time increasing the hardness and strength of the steel, and improving the compressive and tensile strengths of the waterproof cover.

[0021] Furthermore, the waterproof cover is made of stainless steel material, and the service life is the same as the service life of the fan, reducing the replacement and operation and maintenance costs.

[0022] Furthermore, a waterproof portion is provided at the connection gap between the upper tower barrel and the lower tower barrel to further protect the connection gap between the upper tower barrel and the lower tower barrel and further improve the waterproof effect.

[0023] Furthermore, the fifth waterproof surface is connected to the lower tower barrel through fasteners, and the fasteners abut against the outer peripheral surface of the lower tower barrel, increasing the friction between the waterproof cover and the lower tower barrel, reducing the sway of the waterproof cover, and improving the stability of the entire waterproof structure.

[0035] Embodiment 1

[0036] Refer to Figures 1 to 4 , this embodiment provides a waterproof structure for a mixed tower, which is installed at the connection between the upper tower barrel 2 and the lower tower barrel 1, and includes a waterproof cover 3, a waterproof part 6 and 24 support columns 4. The 24 support columns 4 are evenly welded to the outer circumference of the lower part of the upper tower barrel along the circumferential direction. The upper part of the waterproof cover 3 is fixedly connected to the 24 support columns 4 through 24 bolts, and the lower part is abutted against the lower sleeve through a plurality of fasteners 5. The fasteners 5 are coated with locking glue, and it should be ensured that the gaps on the entire ring body are consistent and there is no obvious deviation to one side; among them, the lower tower barrel 1 is a concrete tower barrel, and the upper tower barrel 2 is a steel tower barrel.

[0037] Among them, the waterproof cover 3 is an annular shell, and the upper end size of the waterproof cover 3 is adapted to the upper tower barrel 2, and the lower end size is adapted to the lower tower barrel.

[0038] The waterproof cover 3 can be made of stainless steel material or other materials with anti-corrosion properties.

[0039] The waterproof cover 3 is hot-dip galvanized, the zinc layer thickness is 70um, and the outer surface is sprayed with tower barrel topcoat, and the thickness of the tower barrel topcoat is 50um.

[0040] Preferably, the waterproof cover 3 includes 8 waterproof parts fixedly connected in sequence end to end through bolts. The waterproof parts are manufactured in the factory and assembled and installed on site.

[0041] Sixteen fasteners 5 are evenly distributed circumferentially along the lower edge of the waterproof cover 3.

[0042] The installation method of the above-mentioned mixed tower frame waterproof cover and waterproof structure is as follows:

[0043] Weld a total of 24 support columns 4 in a circle on the outer wall of the steel tower barrel. Make a waterproof cover 3 suitable for the diameters of the steel tower barrel and the concrete tower barrel using stainless steel material, and fixedly connect the waterproof cover 3 to the support columns 4 through bolts. When installing the fitting surface of the waterproof cover 3 and the upper tower barrel 2, apply weather-resistant sealant, ensure that it is extruded and cleaned after the bolts are tightened. At the same time, apply sealant to the bolts of each connecting part of the waterproof cover 3 before tightening to ensure that there is no gap in the fitting surface. The weather-resistant sealant has good elasticity and flexibility, can form an accurate seal on the surfaces of various shapes and materials, and maintain its elasticity, softness and relaxation. After installation, all bolt connection pairs are painted once with tower barrel paint for supplementary anti-corrosion. After the waterproof cover 3 is installed, in rainy or foggy days, when water flows down along the steel tower barrel wall, the waterproof cover guides the water flow to fall outside the tower barrel wall, eliminating the risk of water flow penetrating into the tower barrel interior.
