Description

Technical Field

[0001] This utility model belongs to the field of concrete component technology, specifically relating to a support structure and a concrete tower. Background Technology

[0002] Existing wind turbine towers employ a segmented cylindrical structure, with the diameter of each segment gradually decreasing from bottom to top, thus forming a conical structure with good bending and shear resistance. However, this type of tower structure requires a large amount of building materials and a large number of molds for manufacturing each segment, resulting in higher costs.

[0003] If a straight tower structure is used, the cost is relatively low, but the tower's shear, bending, and pull-out resistance will decrease. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a support structure and a concrete tower.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A support structure includes a ground foundation, a tower fixed on the ground foundation, and a tower support structure provided on the ground foundation. One end of the tower support structure is fixedly connected to the middle of the tower, and the other end is fixedly connected to the ground foundation.

[0007] In the aforementioned support structure, the tower support structure includes a tower support base sleeved on and fixedly connected to the tower, and at least three support rods. One end of each support rod is hinged to the tower support base, and the other end is hinged to the ground foundation.

[0008] In the aforementioned support structure, the angle between the support rod and the ground foundation is 30-75°, and the tower is cylindrical.

[0009] In the aforementioned support structure, the ground foundation includes a base platform, with base platform support piles connected below the base platform, and the bottom of the tower is fixedly connected to the base platform.

[0010] In the aforementioned support structure, the ground foundation further includes at least three support rod bases. Support rod base support piles are connected below the support rod bases. Each support rod base corresponds to a support rod, and one end of each support rod is hinged to the tower support seat, while the other end is hinged to a support rod base. Each support rod base is also provided with a support rod reinforcing rod corresponding to each support rod. One end of each support rod reinforcing rod is fixedly connected to the support rod, and the other end is fixedly connected to the support rod base.

[0011] In the aforementioned support structure, an adjusting tensioning assembly is provided between the support rod and the support rod base. Rotating the adjusting tensioning assembly can increase or decrease the distance between the support rod and the support rod base.

[0012] In the aforementioned support structure, the adjusting tensioning assembly includes a positive and negative threaded screw, a positive threaded sleeve, and a negative threaded sleeve.

[0013] The positive threaded sleeve is fixed to the end of the support rod away from the tower support base, and the negative threaded sleeve is hinged to the base of the support rod. The positive and negative thread sections of the positive and negative threaded rods correspond to the positive threaded sleeve and the negative threaded sleeve, respectively.

[0014] or,

[0015] The reverse threaded sleeve is fixed to the end of the support rod away from the tower support base, and the forward threaded sleeve is hinged to the base of the support rod. The forward and reverse threaded sections of the forward and reverse threaded rods correspond to the forward threaded sleeve and the reverse threaded sleeve, respectively.

[0016] In the aforementioned support structure, the tower support base is further provided with a secondary support structure. One end of the secondary support structure is fixedly connected to the tower support base, and the other end is fixedly connected to the upper middle part of the tower.

[0017] In the aforementioned support structure, the secondary support structure includes a secondary support base fixedly connected to the upper part of the tower, and at least three secondary struts, one end of which is hinged to the secondary support base and the other end of which is hinged to the tower support base.

[0018] A concrete tower with the aforementioned support structure.

[0019] Compared with existing technologies, the advantages of this invention are: it employs a support structure to support the tower, thereby improving the tower's bending and shear resistance. Due to the tower support structure, a cylindrical tower can replace the existing conical tower, reducing material usage and lowering costs. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 As shown, a support structure includes a ground foundation 1 and a tower 2 fixed on the ground foundation 1. In this embodiment, the tower 2 is cylindrical. A tower support structure 3 is provided on the ground foundation 1. One end of the tower support structure 3 is fixedly connected to the middle of the tower 2, and the other end is fixedly connected to the ground foundation 1. The tower support structure 3 actually provides external support for the tower 2.

[0024] Existing towers, or wind turbine towers, are typically tapered structures that are wider at the bottom and narrower at the top. This type of structure, due to its wide base and gradually tapering upwards, offers good resistance to bending and shearing. However, this structural shape requires a relatively large amount of building materials and occupies a significant amount of space at the base.

[0025] Using a cylindrical tower can significantly reduce the amount of material used and the building area occupied at the base of the tower. However, cylindrical towers are less resistant to bending and shearing than conical towers.

[0026] To improve the bending and shear resistance of the cylindrical tower, this embodiment provides the aforementioned tower support structure 3. One end of the tower support structure 3 forms a fixed support with the ground foundation 1, and the other end forms a fixed support for the middle part of the tower 2, thereby improving the bending and shear resistance of the tower 2. It should be noted that the middle part of the tower 2 referred to in this embodiment does not necessarily have to be half the height of the tower 2; it can be a general range. For example, if the tower 2 is divided into three equal parts along its height, the middle part can be defined as the middle part. Alternatively, the middle part can be defined as the portion of the tower 2's height from the bottom upwards (30-70%). The specific position where the top of the tower support structure 3 is fixed to the tower 2 can be determined based on the actual construction conditions. The applicant found that if the support position of the tower support structure 3 to the tower 2 is too low, it will lead to insufficient support; if the support position is too high, the wind turbine blades at the top of the tower will interfere with the tower support structure 3.

[0027] Tower support structure 3 can be a scaffold structure, but this structure is time-consuming to install and its strength is generally average.

[0028] In this embodiment, the tower support structure 3 includes a tower support base 4 sleeved on and fixedly connected to the tower 2, and at least three support rods 5. The support rods 5 are evenly spaced, with one end of each support rod 5 hinged to the tower support base 4 and the other end hinged to the ground foundation 1. This hinge connection can also be a nut and bolt connection or welding, depending on construction convenience. Regardless of the connection method, both ends of the support rod 5 are respectively pressed against the tower support base 4 and the ground foundation 1. Since the tower support base 4 is fixed to the tower 2, the support rod 5 effectively presses against the tower 2.

[0029] The support rod 5 can be made of metal or concrete. The support rod 5 can be a single rod or multiple rods welded or connected together depending on the length.

[0030] The tower support base 4 is typically made of metal. At the point in the middle of the tower 2 where it needs to be fixedly connected to the tower support base 4, connecting steel bars or nuts can be pre-embedded to facilitate connection. Alternatively, the tower support base 4 can also be made of concrete. Preferably, the tower support base 4 uses a metal clamp, which makes connection to the tower 2 easier.

[0031] The angle between the support rod 5 and the ground foundation 1 is 30-75°, preferably 60°. Here, the ground foundation 1 can also be understood as a horizontal plane.

[0032] The ground foundation 1 includes a base platform 6, which is cast in concrete. Base platform support piles 7 are connected below the base platform 6. These support piles 7 are precast piles, driven into the soil below the base platform 6 before the base platform 6 is constructed. The base platform 6 is then constructed on top of the support piles 7, providing support. The bottom of the tower 2 is fixedly connected to the base platform 6. Alternatively, the tower 2 can be a precast component, fixed by welding internal reinforcing bars to the reinforcing bars of the base platform 6, and then concrete is poured to form the base platform 6, thus creating a fixed connection between the base platform 6 and the bottom of the tower 2.

[0033] The ground foundation 1 also includes at least three support rod bases 8. Support rod base support piles 8a are connected to the bottom of each support rod base 8. These support rod base support piles 8a are also precast piles, which can be driven into the ground obliquely or vertically. Each support rod base 8 corresponds one-to-one with a support rod 5, and one end of each support rod 5 is hinged to the tower support base 4, while the other end is hinged to a support rod base 8. It should be noted that the two ends of the support rod 5 can also be connected to the tower support base 4 and the support rod base 8 respectively by welding or screwing. The support rod base 8 serves to position the support rod 5, ensuring that the bottom position of the support rod 5 does not shift, thus providing stable support for the tower 2.

[0034] An adjusting tensioning assembly 9 is provided between the support rod 5 and the support rod base 8. Rotating the adjusting tensioning assembly 9 can increase or decrease the distance between the support rod 5 and the support rod base 8. During the installation of the support rod 5, there will be a certain deviation between the distance between the support rod base 8 and the tower support seat 4 and the length of the support rod 5. This deviation can be effectively overcome by adjusting the tensioning assembly 9, and the installation is convenient.

[0035] Specifically, the adjusting tensioning assembly 9 includes a threaded rod 11 with positive and negative threads, a positive threaded sleeve 12, and a negative threaded sleeve 13. The positive threaded sleeve 12 is fixed to the end of the support rod 5 away from the tower support base 4, and the negative threaded sleeve 13 is hinged to the support rod base 8. The positive and negative threaded sections of the threaded rod 11 correspond to the positive threaded sleeve 12 and the negative threaded sleeve 13, respectively. Alternatively, the negative threaded sleeve 13 is fixed to the end of the support rod 5 away from the tower support base 4, and the positive threaded sleeve 12 is hinged to the support rod base 8. The positive and negative threaded sections of the threaded rod 11 correspond to the positive threaded sleeve 12 and the negative threaded sleeve 13, respectively. The forward and reverse threaded screw 11 is existing technology and commercially available products can be used. Its two ends are forward threaded sections and reverse threaded sections, respectively, and the middle is a wrench rotating part 11a. When the wrench rotating part is rotated in the forward direction, the forward threaded sleeve and the reverse threaded sleeve move closer to each other, that is, the distance between the support rod 5 and the support rod base 8 is shortened. Conversely, the forward threaded sleeve and the reverse threaded sleeve move further apart, thereby achieving the purpose of distance adjustment.

[0036] The support rod base 8 is also provided with support rod reinforcing rods 10 corresponding to the support rods 5. One end of the support rod reinforcing rod 10 is fixedly connected to the support rod 5, and the other end is fixedly connected to the support rod base 8. The support rod reinforcing rod 10 and the support rod 5 form a triangular structure, which plays a role in fixing and supporting, and greatly improves the bending resistance and shear resistance of the support rod 5.

[0037] The tower support base 4 is also equipped with a secondary support structure 14. One end of the secondary support structure 14 is fixedly connected to the tower support base 4, and the other end is fixedly connected to the upper part of the tower 2. The secondary support structure 14 can be understood as providing support for different parts of the tower 2, thereby further improving the tower's bending and shear resistance. The "upper part" refers to the secondary support structure 14 being located above the tower support base 4, and its height is higher than that of the tower support structure 3. Of course, those skilled in the art should understand that one or more secondary support structures 14 can be provided.

[0038] Specifically, the secondary support structure 14 includes a secondary support base 15 fixedly connected to the upper part of the tower 2, and at least three secondary struts 16. The secondary struts 16 are also evenly distributed. One end of each secondary strut 16 is hinged to the secondary support base 15, and the other end is hinged to the tower support base 4, or they can be welded or screwed together. If the secondary support structure 14 is to be further configured, secondary struts 16 can be fixed to the secondary support base 15, and secondary support bases 15 can be connected to the secondary struts 16, similar to the principle of building blocks.

[0039] like Figure 1As shown, for ease of connection, positive and negative threaded rods can also be installed on the secondary support rod 16 and the secondary support base 15, along with corresponding positive and negative threaded sleeves, to adjust the distance between them. The principle is the same as that of the aforementioned adjusting tensioning assembly 9.

[0040] This embodiment also provides a concrete tower cylinder, including the aforementioned support structure, that is, the tower cylinder includes the support structure of this application.

[0041] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.
