[0003] The current tower structures have several problems: First, construction is complex, time-consuming, and costly, requiring a large amount of manpower and equipment to be on-site for extended periods. Second, large, ultra-high-rise cranes are needed for hoisting, but some tower locations are not suitable for their access and use. Summary of the Invention
[0004] The technical problem to be solved by this application is to provide a concrete tower, a method for constructing a concrete tower, and a wind turbine generator, in order to address the above-mentioned shortcomings of the prior art.
[0005] A concrete tower cylinder, the concrete tower cylinder comprising: A tower column is erected on the ground. The tower column comprises multiple hollow telescopic cylinders nested together to form a telescopic structure, with adjacent cylinders forming a sealed sliding fit. The telescopic structure contains a sealed inner cavity. The bottom structure of the inner cavity is located on the lowest telescopic cylinder, and the top structure is located on the uppermost telescopic cylinder. As a water supply device injects liquid into the inner cavity of the tower column, the tower column can extend upwards to a predetermined height under the pressure of the water within the cavity. The liquid is water or an aqueous solution containing water. After the tower column extends upward to the predetermined height, concrete is pumped into the inner cavity of the tower column using a concrete pumping device, and the liquid in the inner cavity is discharged, so that the inner cavity of the tower column is filled with concrete.
[0006] Optionally, when concrete is pumped into the inner cavity of the tower column using a concrete pumping device, the concrete enters from the bottom of the inner cavity; and as the concrete is injected into the inner cavity, the concrete squeezes the liquid in the inner cavity, causing the liquid in the inner cavity to be discharged upward under pressure.
[0007] Optionally, the concrete tower includes multiple tower columns and connecting structures; The multiple tower columns are erected at different locations on the ground; The connecting structure connects the individual tower columns together, thus forming a structural whole together with the individual tower columns.
[0008] Optionally, for any two adjacent telescopic cylinders on the tower column, the upper telescopic cylinder is inserted into the lower telescopic cylinder.
[0009] Optionally, the tower columns are evenly distributed around the perimeter of the concrete tower cylinder.

[0011] Optionally, the connection structure consists of multiple connectors, each connector connecting the telescopic cylinders on two different tower columns.
[0012] On the other hand, this application also provides a method for constructing a concrete tower, the method comprising: Multiple tower columns are erected at different locations on the ground; each tower column includes multiple hollow telescopic cylinders; the telescopic cylinders are nested together to form a telescopic structure, and adjacent telescopic cylinders form a sealed sliding fit; the telescopic structure has a sealed inner cavity; the bottom structure of the inner cavity is located on the lowermost telescopic cylinder, and the top structure of the inner cavity is located on the uppermost telescopic cylinder; in the initial state, the telescopic cylinders of the tower column are retracted together; Liquid is injected into the inner cavity of each tower column using a water supply device, and each telescopic cylinder extends upward under the drive of the water pressure inside the tower column. The connecting structures are used to connect the individual tower columns together, and the connecting structures and the individual tower columns together form a structural whole. After the tower columns extend upward to the predetermined height, concrete is pumped into the inner cavity of each tower column using a concrete pumping device, and the liquid in the inner cavity is discharged, so that the inner cavity of the tower column is filled with concrete.
[0013] Optionally, driven by the water pressure inside the tower column, each telescopic cylinder extends upward in sequence from top to bottom; and the telescopic cylinders of each tower column extend synchronously, so that a set of telescopic cylinders corresponding to the height position extends synchronously each time; and a connecting structure is used to connect the set of telescopic cylinders to be extended together before each set of telescopic cylinders extends.
[0014] Optionally, the connection structure includes multiple connectors, each connector connecting to a telescopic cylinder on two different tower columns.
[0015] On the other hand, this application also provides a wind turbine having the aforementioned concrete tower.
[0016] The concrete tower provided in this application utilizes a telescopic structure to construct tower columns as the main structure. During on-site construction, a water supply device injects liquid into the inner cavity of the tower column, driving the column to extend upwards to a predetermined height.

[0029] The following are specific embodiments of this application, described in conjunction with the accompanying drawings, to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.
[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.
[0031] Towers are widely used in production and daily life, such as communication towers, power transmission line towers, and wind turbine towers. Among these, the wind turbine tower is the core supporting structure of a wind power generation system, playing a crucial role in lifting the wind turbine and nacelle to high altitudes to capture stronger and more stable wind energy. Existing tower construction is complex, time-consuming, and costly, requiring significant manpower and equipment to be on-site for extended periods. Furthermore, large, ultra-high-altitude cranes are needed for hoisting, and some tower locations are not suitable for their access and operation.
[0032] Therefore, this application provides a concrete tower and a method for constructing a concrete tower. During on-site construction, the concrete tower provided by this application can utilize a water supply device to inject liquid into the inner cavity of each tower column, driving the tower column to extend upwards to a predetermined height. This eliminates the need for large, ultra-high-altitude cranes for hoisting, and the construction is simple, time-saving, and cost-effective. The following is a combination of... Figures 1-10 This application provides a detailed description of the concrete tower and the method for constructing the concrete tower.
[0033] refer to Figure 1 and Figure 2The concrete tower 100 includes multiple tower columns 10 and a connecting structure 20. The tower columns 10 are erected at different locations on the ground S. Each tower column 10 includes multiple hollow telescopic cylinders 11. The telescopic cylinders 11 are nested together to form a telescopic structure, with adjacent telescopic cylinders 11 forming a sealed sliding fit. A sealed inner cavity 12 is formed inside the telescopic structure. The bottom structure of the inner cavity 12 is located on the lowermost telescopic cylinder 11, and the top structure of the inner cavity 12 is located on the uppermost telescopic cylinder 11. As the water supply device 30 injects liquid into the inner cavity 12 of each tower column 10, each tower column 10 can extend upwards to a predetermined height under the drive of the water pressure within the cavity. The liquid is water or an aqueous solution containing water. The connecting structure 20 connects the tower columns 10 together, thus forming a structural whole with each tower column 10.
[0034] When constructing the concrete tower 100, the tower column 10 needs to be fabricated first. The tower column 10 can be prefabricated in the factory and then transported to the construction site. During transportation, the tower column 10 is in a retracted state, which reduces its volume and makes transportation more convenient. The tower column 10 is a telescopic structure, consisting of multiple hollow telescopic cylinders 11 nested together, forming a sealed inner cavity 12. Adjacent telescopic cylinders 11 form a sealed sliding fit. Therefore, when the water supply device 30 injects liquid into the inner cavity 12 of the tower column 10, the tower column 10 can extend upward to a predetermined height under the drive of the water pressure in the inner cavity.
[0035] The tower column 10 is a telescopic structure, consisting of multiple hollow telescopic cylinders 11 nested together. In one embodiment of this application, for any two adjacent telescopic cylinders 11 on the tower column 10, the upper telescopic cylinder 11 is inserted into the lower telescopic cylinder 11.
[0036] During on-site construction, workers erect multiple tower columns 10 at different locations on the ground S. On one hand, during construction, workers can use a water supply device 30 to raise each tower column 10 to a predetermined height, eliminating the need for large, high-altitude cranes for hoisting. This method is simpler, faster, and less costly. On the other hand, workers connect the tower columns 10 together using a connecting structure 20, forming a stable structural unit. Furthermore, compared to cylindrical concrete towers (e.g., cylindrical wind turbine concrete towers), the concrete tower structure of this application, consisting of the connecting structure 20 and the tower columns 10, is less expensive and overcomes height limitations.
[0037] After the tower column 10 extends upward to the predetermined height, concrete is pumped into the inner cavity 12 of each tower column 10 using a concrete pumping device 40, and the liquid in the inner cavity 12 is discharged, so that the inner cavity 12 of the tower column 10 is filled with concrete. Finally, the telescopic structure formed by the telescopic cylinder 11 and the internal concrete form a stable integrated structure.
[0038] In one embodiment of this application, when concrete is pumped into the inner cavity of the tower column using a concrete pumping device, the concrete enters from the bottom of the inner cavity; and as the concrete is injected into the inner cavity, the concrete squeezes the liquid in the inner cavity, causing the liquid in the inner cavity to be discharged upward under pressure; the inner cavity maintains pressure during the concrete injection process.
[0039] In one embodiment of this application, the tower columns 10 are evenly distributed around the perimeter of the concrete tower cylinder. (See reference...) Figure 1 and Figure 2 Six tower columns are evenly arranged around the concrete tower.
[0040] In one embodiment of this application, the telescopic cylinders 11 of each tower column 10 are uniformly distributed at height to form a one-to-one correspondence. The connecting structure 20 includes multiple sub-connecting structures 20 located at different heights, and the telescopic cylinders 11 of each tower column 10 at the same height are connected together by corresponding sub-connecting structures 20. (See reference) Figure 1 and Figure 2 The concrete tower 100 forms multiple structural units at different heights from bottom to top. Each structural unit includes a telescopic cylinder 11 at the same height of each tower column 10 and a corresponding sub-connecting structure 20. The sub-connecting structure 20 connects the telescopic cylinders 11 at the corresponding height together.
[0041] In one embodiment of this application, the connection structure 20 is composed of a plurality of connectors 21, each connector 21 connecting to a telescopic cylinder 11 on two different tower columns 10. (See reference...) Figure 1 and Figure 2 The connector 21 is a rod-shaped structure, with its two ends connected to the telescopic cylinders 11 on two different tower columns 10 respectively. Through the connection of multiple connectors 21, all the tower columns 10 are connected together to form an integral structure.
[0042] This application also provides a method for constructing a concrete tower, which can be used to construct the concrete tower provided in the previous part. The method for constructing the concrete tower includes steps 101 and 102.
[0043] Step 101: Erect multiple tower columns 10 at different locations on the ground S; wherein, each tower column 10 includes multiple hollow telescopic cylinders 11; the telescopic cylinders 11 are nested together to form a telescopic structure, and adjacent telescopic cylinders 11 form a sealed sliding fit; a sealed inner cavity 12 is formed inside the telescopic structure; the bottom structure of the inner cavity 12 is located on the lowermost telescopic cylinder 11, and the top structure of the inner cavity 12 is located on the uppermost telescopic cylinder 11; in the initial state, each telescopic cylinder 11 of the tower column 10 is retracted together.
[0044] Step 102: Liquid is injected into the inner cavity 12 of each column 10 using the water supply device 30. Driven by the water pressure in the inner cavity of the column 10, each telescopic cylinder 11 extends upward in sequence from top to bottom. The telescopic cylinders of each column extend synchronously, so that a set of telescopic cylinders corresponding to the height position extends synchronously each time. Before each set of telescopic cylinders 11 extends, the connecting structure 20 is used to connect the set of telescopic cylinders 11 to be extended together.
[0045] When constructing the concrete tower 100, the tower column 10 needs to be fabricated first. The tower column 10 can be prefabricated in the factory and then transported to the construction site. During transportation, the tower column 10 is in a contracted state, which reduces its volume and makes transportation more convenient. The tower column 10 is a telescopic structure, consisting of multiple hollow telescopic cylinders 11 nested together, forming a sealed inner cavity 12. Adjacent telescopic cylinders 11 form a sealed sliding fit.
[0046] In step 101, refer to Figure 3 and Figure 4 Multiple tower columns 10 are erected at different locations on the ground S, and all tower columns 10 are in their initial state, with each telescopic cylinder 11 retracted together.
[0047] In step 102, liquid is injected into the inner cavity 12 of each column 10 using a water supply device 30. Driven by the water pressure in the inner cavity 12 of the column, each telescopic cylinder 11 extends upward in sequence from top to bottom. Specifically, the sequence from top to bottom along each column is: first telescopic cylinder, second telescopic cylinder, ..., i-th telescopic cylinder. (First refer to...) Figure 5 The first telescopic cylinders on each tower column are connected together using the connecting structure 20. Then refer to... Figure 6 After the connecting structure 20 connects the first telescopic cylinders on each tower column, the water supply device 30 injects liquid into the inner cavity 12 of each tower column 10. Driven by the water pressure inside the tower column 10, the first telescopic cylinders on each tower column extend synchronously. (The rest of the text is a continuation of the previous paragraph.) Figure 7 The second telescopic cylinders on each tower column are connected together using the connecting structure 20. Then, the water supply device 30 continues to inject liquid into the inner cavity 12 of each tower column 10, causing the second telescopic cylinders on each tower column to extend synchronously. This operation is repeated. Finally, the i-th telescopic cylinders on each tower column are connected together using the connecting structure 20. Then, the water supply device 30 continues to inject liquid into the inner cavity 12 of each tower column 10, causing the i-th telescopic cylinders on each tower column to extend synchronously. At this point, the concrete tower reaches the predetermined height.
[0048] The concrete tower construction method also includes step 103, in which, after the tower column 10 extends upward to a predetermined height, concrete is pumped into the inner cavity 12 of each tower column 10 using a concrete pumping device 40, and the liquid in the inner cavity 12 is discharged, so that the inner cavity 12 of the tower column 10 is filled with concrete.
[0049] After the tower column 10 extends upward to the predetermined height, concrete is pumped into the inner cavity 12 of each tower column 10 using a concrete pumping device 40, and the liquid in the inner cavity 12 is discharged, so that the inner cavity 12 of the tower column 10 is filled with concrete. Finally, refer to Figure 10 The telescopic structure formed by the telescopic cylinder 11 and the internal concrete form a stable integrated structure.
[0050] Figures 8-10 The process of concrete pumping device 40 pumping concrete into the tower column is shown. Figures 8-10 In the diagram, A represents the internal cavity space occupied by the liquid, and B represents the internal cavity space occupied by the concrete. Figure 8 The image shows the state of the tower column 10 before concrete is pumped in, in which the inner cavity 12 of the tower column 10 is filled with liquid. Figure 9 The diagram shows the intermediate state of the tower column 10 being pumped with concrete. In this state, the lower part of the inner cavity of the tower column 10 is filled with concrete, and the upper part of the inner cavity is filled with liquid. Figure 10 The final state of the column 10 being pumped with concrete is shown. In this state, the inner cavity 12 of the column 10 is filled with concrete and the liquid has been completely drained.
[0051] In one embodiment of this application, the connection structure 20 includes a plurality of connectors 21, each connector 21 connecting to a telescopic cylinder 11 on two different tower columns 10. (See reference...) Figure 1 and Figure 2 The connector 21 is a rod-shaped structure, with its two ends connected to the telescopic cylinders 11 on two different tower columns 10 respectively. Through the connection of multiple connectors 21, all the tower columns 10 are connected together to form an integral structure.
[0052] In one embodiment of this application, for any two adjacent telescopic cylinders 11 on the tower column 10, the upper telescopic cylinder 11 is inserted into the lower telescopic cylinder 11.
[0053] In one embodiment of this application, the tower columns 10 are evenly distributed around the perimeter of the concrete tower cylinder. (See reference...) Figure 1 and Figure 2 Six tower columns are evenly arranged around the concrete tower.
[0054] In one embodiment of this application, the telescopic cylinders 11 of each tower column 10 are uniformly distributed at height to form a one-to-one correspondence. The connecting structure 20 includes multiple sub-connecting structures 20 located at different heights, and the telescopic cylinders 11 of each tower column 10 at the same height are connected together by corresponding sub-connecting structures 20. (See reference) Figure 1 and Figure 2 The concrete tower 100 forms multiple structural units at different heights from bottom to top. Each structural unit includes a telescopic cylinder 11 at the same height of each tower column 10 and a corresponding sub-connecting structure 20. The sub-connecting structure 20 connects the telescopic cylinders 11 at the corresponding height together.
[0055] The concrete tower construction method provided in this embodiment can be used to construct the concrete tower provided in the previous part, and the descriptions of related technical means can be referred to each other.
[0056] It should be understood that in this application, the water supply device 30 is used to inject liquid into the inner cavity 12 of each tower column 10, and may include components such as liquid injection pipelines, pumps, and water valves. The concrete pumping device 40 is used to pump concrete into the inner cavity 12 of the tower column 10, and includes a concrete pump. Both the water supply device 30 and the concrete pumping device 40 are commonly used devices in the prior art, and can be found in the relevant prior art, which will not be described in detail here.

After the tower column extends upward to the predetermined height, a concrete pumping device pumps concrete into the inner cavity of the tower column and discharges the liquid in the inner cavity, so that the inner cavity of the tower column is filled with concrete.
[0058] The tower column is a telescopic structure, composed of multiple nested hollow telescopic cylinders. In one embodiment of this application, for any two adjacent telescopic cylinders on the tower column, the upper telescopic cylinder is inserted into the lower telescopic cylinder. Compared to the concrete tower cylinder provided in the previous section, the concrete tower cylinder provided in this embodiment only contains one tower column, making its structure simpler. Furthermore, the structure of the tower column can be found in the description in the previous section, and will not be repeated here.
[0059] In one embodiment of this application, when concrete is pumped into the inner cavity of the tower column using a concrete pumping device, the concrete enters from the bottom of the inner cavity; and as the concrete is injected into the inner cavity, the concrete squeezes the liquid in the inner cavity, causing the liquid in the inner cavity to be discharged upward under pressure; the inner cavity maintains a certain pressure during the concrete injection process.
[0060] Compared to the concrete tower provided in the previous section, the concrete tower provided in this embodiment only contains one tower column, which is simpler in structure and has similar technical effects, so it will not be described in detail here.
[0061] This application also provides a wind turbine generator, see reference. Figure 11 The wind turbine has the aforementioned concrete tower 100.
[0062] In some embodiments of this application, the concrete tower 100 includes multiple tower columns 10 and a connecting structure 20. The tower columns 10 are erected at different positions on the ground S; each tower column 10 includes multiple hollow telescopic cylinders 11; the telescopic cylinders 11 are nested together to form a telescopic structure, with adjacent telescopic cylinders 11 forming a sealed sliding fit; a sealed inner cavity 12 is formed inside the telescopic structure; the bottom structure of the inner cavity 12 is located on the lowermost telescopic cylinder 11, and the top structure of the inner cavity 12 is located on the uppermost telescopic cylinder 11; as the water supply device 30 injects liquid into the inner cavity 12 of each tower column 10, each tower column 10 can extend upward to a predetermined height under the drive of the water pressure in the inner cavity; the liquid is water or an aqueous solution containing water. The connecting structure 20 connects the tower columns 10 together, thus forming a structural whole with each tower column 10.
[0063] In some embodiments of this application, the concrete tower includes a tower column erected on the ground; the tower column includes multiple hollow telescopic cylinders; the telescopic cylinders are nested together to form a telescopic structure, with adjacent telescopic cylinders forming a sealed sliding fit; the telescopic structure has a sealed inner cavity; the bottom structure of the inner cavity is located on the lowermost telescopic cylinder, and the top structure of the inner cavity is located on the uppermost telescopic cylinder; as a water supply device injects liquid into the inner cavity of the tower column, the tower column can extend upward to a predetermined height under the drive of the water pressure in the inner cavity, the liquid being water or an aqueous solution containing water. After the tower column extends upward to the predetermined height, a concrete pumping device pumps concrete into the inner cavity of the tower column and discharges the liquid in the inner cavity, so that the inner cavity of the tower column is filled with concrete.
[0064] For a more detailed explanation, please refer to the previous section on concrete towers and their construction methods; it will not be repeated here.
[0065] It should be noted that, in this application, the liquid is water or an aqueous solution containing water.
[0066] In summary, the concrete tower provided in this application utilizes a telescopic structure to construct tower columns as the main structure of the concrete tower, and connects these columns together using a connecting structure to form a unified structural unit. During on-site construction, a water supply device injects liquid into the inner cavity of each tower column, driving the column to extend upwards to a predetermined height. After the column reaches the predetermined height, a concrete pumping device pumps concrete into the inner cavity of each tower column, discharging the liquid from the inner cavity, thus filling the inner cavity of the tower column with concrete. The concrete tower provided in this application eliminates the need for large, ultra-high-altitude cranes during construction, and its construction is simple, time-efficient, and cost-effective.
