Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine generator equipment, specifically to a segmented tower with a sealing and waterproof function. Background Technology

[0002] With the continuous increase in the capacity of wind turbine generators and the urgent need for high-altitude wind energy utilization in areas with large wind shear variations, wind turbine towers with a height of more than 100 meters are increasingly favored by the market. In order to meet the demand for building and using tall towers, and to increase the stability of tall towers, the diameter of the base of the tower needs to be made larger and larger to achieve better results.

[0003] The sealing and waterproofing requirements of the welded joints of the large-diameter segmented tower body are crucial for the later operation of the wind turbine. Because the longitudinal flanges of the segmented tower are connected by bolts, the longitudinal cut seams of the segmented tower body cannot be completely sealed, resulting in water ingress through the gaps. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the issue of water ingress at the cut seams of existing segmented towers, which leads to water accumulation inside the tower. This utility model provides a segmented tower with a compact structure, convenient assembly and disassembly, high reliability, and sealing and waterproof functions.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A segmented tower with sealing and waterproofing function includes at least two segmented tower sections joined from bottom to top. Each segmented tower section is composed of at least two segmented tower shells. The inner sides of the segmented tower shells are joined by longitudinal flanges to form cylindrical tower ends. The two inner ends of the segmented tower shells are connected by a sealing connection assembly to form a segmented tower section. Two adjacent segmented tower sections are joined together by annular flanges, and a water collection assembly is provided below the annular flanges. The water collection assembly is used to collect rainwater that enters the interior of the segmented tower section from the outer splice joint of the segmented tower section and to lead the rainwater out of the tower section.

[0007] As a further improvement of this utility model, the sealing connection assembly includes a first segmented flange, a first locking block, a second segmented flange, locking bolts, and locking nuts; the first segmented flange and the second segmented flange are respectively fixed to the inner wall surfaces of two interlocking segmented tower shells, and the first segmented flange and the second segmented flange are detachably connected by locking bolts and locking nuts to achieve a detachable connection between two adjacent segmented tower shells.

[0008] As a further improvement of this utility model, the sealing connection assembly further includes a first locking block and a second locking block. The first locking block is fixed inside the first segment flange, and the second locking block is fixed inside the second segment flange. Both the first locking block and the second locking block are provided with connecting holes. Locking bolts are inserted into the connecting holes and locked by locking nuts.

[0009] As a further improvement of this utility model, a locking washer is provided at the connection between the locking bolt and the locking nut and the first locking block and the second locking block.

[0010] As a further improvement of this utility model, the water collection assembly includes a water collection trough, which is fitted and surrounds the inner wall of the segmented tower and is located below the annular flange.

[0011] As a further improvement of this utility model, the water collection assembly also includes a connecting stud and a water collection bottle. The hollow connecting stud is set at the bottom of the water collection tank and communicates with the water collection tank. The water collection bottle is threadedly connected to the connecting stud, and the rainwater in the water collection tank is collected into the water collection bottle.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This utility model discloses a segmented tower with sealing and waterproof functions. Through the installation of sealing connection components, it meets the requirements for rapid positioning and assembly during the segmented tower assembly process, ensuring that the circumferential flange and longitudinal flange meet tolerance requirements after assembly, improving the assembly accuracy of the segmented tower, reducing cylinder misalignment, and enhancing cylinder sealing. The water collection component allows rainwater entering the cylinder through the splicing seams of the segmented tower shell to be channeled into a water collection bottle via a water collection trough, preventing water ingress that could lead to corrosion of the cylinder and bolts, and failure of electrical components, effectively solving the problem of internal water leakage in segmented towers.

[0024] Example

[0025] like Figure 1As shown, the segmented tower with sealing and waterproof function of this utility model includes two segmented tower sections 100 joined together from bottom to top. Each segmented tower section 100 consists of three segmented tower shells. The inner sides of the segmented tower shells are joined by longitudinal flanges 240 to form cylindrical tower ends. The two inner ends of the segmented tower shells are connected by a sealing connection assembly 200 to form a single segmented tower section 100. Two adjacent segmented tower sections 100 are joined together by annular flanges, and a water collection assembly 300 is provided below the annular flanges. The water collection assembly 300 is used to collect rainwater entering the interior of the segmented tower section 100 from the outer seam of the segmented tower and to guide the rainwater out of the tower. In this embodiment, the structures of the segmented tower shells and the annular flanges are conventional and will not be described in detail here.

[0026] In this embodiment, the sealing connection component 200 meets the requirements for rapid positioning and assembly during the segmented tower assembly process, ensuring that the ring flange and longitudinal flange 240 of the segmented tower meet the tolerance requirements after assembly, improving the assembly accuracy of the segmented tower, reducing cylinder misalignment, and enhancing the cylinder's sealing performance. The water collection component 300 collects rainwater entering the segmented tower cylinder 100 through the splicing seams of the segmented tower shell, preventing water ingress that could lead to corrosion of the cylinder and bolts, and failure of electrical components, effectively solving the problem of internal water leakage in the segmented tower.

[0027] like Figure 2 and Figure 3 As shown, the sealing connection assembly 200 includes a first segment flange 210, a second segment flange 220, a locking bolt 231, and a locking nut 233. The first segment flange 210 and the second segment flange 220 are respectively fixed to the inner wall surfaces of two interlocking segmented tower shells. The first segment flange 210 and the second segment flange 220 are detachably connected by the locking bolt 231 and the locking nut 233, thus realizing a detachable connection between two adjacent segmented tower shells.

[0028] Furthermore, the sealing connection assembly 200 also includes a first locking block 211 and a second locking block 221. The first locking block 211 is fixed inside the first segment flange 210, and the second locking block 221 is fixed inside the second segment flange 220. Both the first locking block 211 and the second locking block 221 are provided with connection holes. Locking bolts 231 are inserted into the connection holes and locked by locking nuts 233.

[0029] Locking washers 232 are provided at the connection between the locking bolt 231 and the first locking block 211, and at the connection between the locking nut 233 and the second locking block 221, to improve the reliability of the sealing connection.

[0030] In this embodiment, adjacent segmented tower sections 100 of the tower body are joined together by annular flanges at the top or bottom of the segmented tower sections 100. When the annular flanges of the upper and lower segmented tower sections 100 are joined together, there will be gaps, and external water may enter the tower body through these gaps. In view of this, a water collection assembly 300 is provided below the annular flanges inside the segmented tower.

[0031] like Figure 4 , Figure 5 and Figure 6 As shown, the water collection assembly 300 includes a water collection tank 301, which fits and surrounds the inner wall of the segmented tower 100 and is located below the annular flange and also below the sealing connection assembly 200.

[0032] In this embodiment, the water collection assembly 300 further includes a connecting stud 302 and a water collection bottle 303. The connecting stud 302 has a hollow internal structure and is threaded on its outer side. The connecting stud 302 is located at the bottom of the water collection trough 301 and communicates with it. The water collection bottle 303 has an internal thread at its opening, which is threaded to the connecting stud 302, allowing for convenient assembly and disassembly and reliable connection. Rainwater in the water collection trough 301 is collected into the water collection bottle 303 and then led to the outside of the segmented tower 100. It can be understood that, to improve the efficiency of rainwater collection, a certain slope can be provided inside the water collection trough 301, and the connecting stud 302 is located at the bottom of the slope, allowing rainwater to flow smoothly into the water collection bottle 303. The water in the water collection bottle 303 is then emptied manually periodically.

[0033] The water collection component 300 collects rainwater that enters the cylinder through the splicing seams of the segmented tower via the water collection trough 301 and the water collection bottle 303, and then leads it out of the tower, preventing water from entering and causing corrosion of the cylinder and bolts and failure of the electrical cabinet. At the same time, in conjunction with the sealing connection component 200 on the outer shell of the segmented tower, it can ensure the sealing and waterproofing of the cylinder, effectively preventing rainwater, sand, flying insects and other substances from entering the tower later, and ultimately solving the problem of the shortcoming of sealing and waterproofing of the segmented tower.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
