Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a wind power generation tower base. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source that has been used by people for a long time. Currently, there are many types of equipment used for wind power generation on the market. Among them, the more common power generation equipment is the power tower. One of the most important supports of the wind tower includes the base.

[0003] The base of a wind turbine tower mainly includes a weighing seat and the bottom of the tower. During assembly, a crane is used to lower the bottom of the tower and lift it up. Then, several workers begin to manually adjust the position of the bottom of the tower and the bolts installed on the load-bearing seat until the position of the bolts is aligned with the flange holes of the flange at the bottom of the tower. Then, the crane begins to control the tower to descend until the bottom of the tower fits with the top of the load-bearing seat. Then, the washer and nut can be put on the bolt to fix the tower. Because the load-bearing seat is mostly made of reinforced concrete and the bolts are pre-buried in the load-bearing seat, the entire tower can be supported after the tower and the bolts are fixed.

[0004] However, in actual use of the wind turbine tower base mentioned above, since the number of bolts is relatively large and the staggered angles between the bolts are relatively small, workers are generally responsible for determining whether the bolts are aligned with the flange holes during installation. If the angle is not accurately confirmed, the bolts may be easily bent and deformed, making the entire adjustment time relatively long. In order to improve installation efficiency, improvements are urgently needed based on the existing wind turbine tower base. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a wind power tower base to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wind power tower base, comprising a bearing seat, bolts, a tower, an outer flange and an inner flange, a main guide block is installed on the top of the bearing seat, and a plurality of main guide blocks are installed at equal angles on the top of the bearing seat, and the outer corners of the top of the main guide block are designed to be beveled, and the cross section of the main guide block is designed to be arc-shaped, and after the tower is installed, the outer wall of the main guide block is in contact with the outer wall of the inner flange;

[0007] The main guide block is installed with an auxiliary guide block near the outer wall of the inner flange, and a positioning groove is penetrated through the outer wall of the inner flange. After the tower is installed, the outer wall of the auxiliary guide block is in contact with the inner wall of the positioning groove.

[0008] By adopting the above technical solution, during the process of aligning the bolts and flange holes, the main guide block will guide the tower, so that workers can quickly determine the center position of the tower and the angle of the tower. The operation of aligning the bolts and flange holes is very simple, making the tower installation efficiency using this base higher.

[0009] The utility model is further configured that the number of the main guide blocks is at least three, and the main guide blocks are pre-embedded and installed inside the load-bearing seat.

[0010] By adopting the above technical solution, the stability of the master boot block during use is ensured.

[0011] The utility model is further configured such that the horizontal plane where the top end of the main guide block is located is higher than the horizontal plane where the top end of the auxiliary guide block is located, and the horizontal plane where the top end of the auxiliary guide block is located is higher than the horizontal plane where the top end of the bolt is located.

[0012] By adopting the above technical solution, it is ensured that the outer flange and the inner flange will not contact the bolts during the process of adjusting the position of the auxiliary guide block and the positioning groove, preventing the outer flange and the inner flange from damaging the bolts during the adjustment process.

[0013] The utility model is further configured that the top corner of the guide block and the bottom corner of the positioning groove are both designed to be beveled, and the bottom end of the guide block is pre-buried inside the load-bearing seat.

[0016] By adopting the above technical solution, the support block can support the main guide block, thereby reducing the probability of deformation of the main guide block.

[0017] The utility model is further configured that a support ring is installed in the load-bearing seat, and the support ring is fixedly connected to multiple groups of support blocks.

[0018] By adopting the above technical solution, it is convenient for workers to install the main guide block, the auxiliary guide block and the support block in the load-bearing seat during construction.

[0019] The utility model is further configured that a support frame is fixedly installed on the inner wall of the support ring, a through hole is opened in the middle of the support frame, and a support steel slidably connected to the through hole is installed in the load-bearing seat.

[0020] By adopting the above technical solution, the stability of the installation position of the support frame is ensured by the support steel.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] The utility model is provided with a main guide block, a secondary guide block and a positioning groove, so that in the process of aligning the bolts and the flange holes, the main guide block will guide the tower, so that the worker can quickly determine the center position of the tower, and adjust the position of the secondary guide block and the positioning groove by rotating the tower.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] A wind power tower base, such as Figure 1-Figure 5As shown, it includes a bearing seat 1, bolts 101, a tower 2, an outer flange 3 and an inner flange 4. A main guide block 5 is installed on the top of the bearing seat 1. At the same time, multiple main guide blocks 5 are installed at equal angles on the top of the bearing seat 1, and the outer corners of the top of the main guide blocks 5 are designed to be beveled. When the tower 2 is descending, the top bevels of the multiple main guide blocks 5 will guide the outer wall of the inner flange 4 at the bottom of the tower 2. Because the cross-section of the main guide blocks 5 is designed to be arc-shaped, the inner flange 4 begins to fit with the outer wall of the main guide blocks 5 after being guided by the main guide blocks 5. Through the setting of the main guide blocks 5, it is convenient for workers to quickly adjust the tower 2 to a state concentric with the bearing seat 1, and then it is convenient to align the outer flange 3 and the inner flange 4 with the bolts 101 later. After the tower 2 is installed, the outer wall of the inner flange 4 will fit with the outer wall of the main guide blocks 5, so as to ensure the stability of the tower 2 during the descent process.

[0032] Furthermore, a secondary guide block 6 is installed on the outer wall of the main guide block 5 close to the inner flange 4, and a positioning groove 7 corresponding to the secondary guide block 6 is opened through the outer wall of the inner flange 4, so that when the center of the tower 2 is determined under the action of the inner flange 4 and the main guide block 5, the position of the secondary guide block 6 and the positioning groove 7 is adjusted by adjusting the angle of the tower 2 until the secondary guide block 6 enters the positioning groove 7. At this time, the secondary guide block 6 and the positioning groove 7 will limit the angle of the tower 2, so that the bolt 101 corresponds to the flange hole. As the tower 2 descends, the bolt 101 will gradually enter the flange hole until the tower 2 is installed. At this time, the outer wall of the secondary guide block 6 is in contact with the inner wall of the positioning groove 7.

[0033] See also Figure 2-Figure 5 The number of main guide blocks 5 is at least three, ensuring that the main guide blocks 5 can smoothly guide the inner flange 4 during the descent of the tower 2. At the same time, the main guide blocks 5 are pre-embedded and installed inside the load-bearing seat 1, so that when the main guide blocks 5 guide and support the inner flange 4, the load-bearing seat 1 will also support the main guide blocks 5, ensuring the stability of the main guide blocks 5 when in use.

[0034] See also Figure 3-Figure 5The horizontal plane at the top of the main guide block 5 is higher than the horizontal plane at the top of the auxiliary guide block 6, so that when the main guide block 5 guides the inner flange 4 and the center position of the tower 2 has not been determined, the inner flange 4 will not contact the auxiliary guide block 6, so that the auxiliary guide block 6 will not affect the main guide block 5 guiding the inner flange 4. At the same time, the horizontal plane at the top of the auxiliary guide block 6 is higher than the horizontal plane at the top of the bolt 101, so that when adjusting the position of the auxiliary guide block 6 and the positioning groove 7, the inner flange 4 will not contact the bolt 101, ensuring that only after the auxiliary guide block 6 slides with the positioning groove 7, the inner flange 4 will drop and contact the bolt 101, ensuring that in the process of adjusting the position of the auxiliary guide block 6 and the positioning groove 7, the outer flange 3 and the inner flange 4 will not contact the bolt 101, preventing the outer flange 3 and the inner flange 4 from damaging the bolt 101 during the adjustment process.

[0035] See also Figure 3-Figure 5 The top corners of the auxiliary guide block 6 and the bottom corners of the positioning groove 7 are both designed with bevel angles, so that when the auxiliary guide block 6 enters the positioning groove 7, the bevel angles of the auxiliary guide block 6 and the positioning groove 7 will enter each other, further reducing the difficulty of the auxiliary guide block 6 entering the positioning groove 7, thereby reducing the difficulty of determining the angle of the tower 2. At the same time, the bottom end of the auxiliary guide block 6 is pre-buried in the load-bearing seat 1, so that the auxiliary guide block 6 will also be supported by the load-bearing seat 1.

[0036] See also Figure 3-Figure 5 A support block 8 fixedly connected to the outer wall of the main guide block 5 is pre-embedded in the load-bearing seat 1. At the same time, because the portion of the top of the support block 8 exposed from the load-bearing seat 1 is designed as a triangular plate, when the end of the main guide block 5 starts to guide the inner flange 4, the support block 8 will use its own shape and the support given to the support block 8 by the load-bearing seat 1 to further support the main guide block 5, further reducing the probability of deformation of the main guide block 5;

[0037] Furthermore, a support ring 9 is installed in the load-bearing seat 1, and the support ring 9 is fixedly connected to multiple groups of support blocks 8, so that the multiple groups of support blocks 8 are connected as a whole through the support ring 9. At the same time, because the support block 8 is fixedly connected to the main guide block 5, the multiple groups of main guide blocks 5 and auxiliary guide blocks 6 and the support block 8 form a whole under the action of the support ring 9, which makes it convenient for workers to install the main guide block 5 and the auxiliary guide block 6 and the support block 8 in the load-bearing seat 1 during construction.

[0038] See also Figure 5A support frame 10 is fixedly installed on the inner wall of the support ring 9, and a through hole is opened in the middle of the support frame 10. At the same time, a support steel 11 slidably connected to the through hole is installed in the load-bearing seat 1, so that when the support ring 9 is installed, since the load-bearing seat 1 is provided with the support steel 11 before pouring, the support frame 10 can be directly installed on the support steel 11. The support steel 11 is used to ensure the stability of the installation position of the support frame 10, and it is also convenient for workers to determine the installation position of the support frame 10 when constructing the load-bearing seat 1.

[0039] The working principle of the utility model is as follows: when using the base to install the tower 2, first, lift the tower 2, then drop the tower 2 above the load-bearing seat 1, then the worker begins to guide the tower 2, so that the tower 2 begins to descend with the guidance of the worker, until the inner wall of the inner flange 4 at the bottom end of the tower 2 contacts the top inclined surface of the main guide block 5, then continue to descend the tower 2, at this time the main guide block 5 will guide the inner flange 4, so that the center position of the tower 2 is limited, then the worker begins to rotate the tower 2, adjusts its angle, until the positioning groove 7 corresponds to the position of the auxiliary guide block 6, at this time the tower 2 will continue to descend, and at the same time the top inclined angle of the auxiliary guide block 6 and the bottom inclined angle of the positioning groove 7 The angles will guide each other, so that the angle of the tower 2 is limited. At the same time, because the length of the auxiliary guide block 6 is greater than the length of the bolt 101, after the angle of the tower 2 is determined, the horizontal plane at its bottom end is still higher than the horizontal plane at which the bolt 101 is located. Then the tower 2 continues to descend. At this time, the outer wall of the auxiliary guide block 6 will limit the inner wall of the tower 2, thereby improving the stability of the angle of the tower 2 during the descent process until the position of the tower 2 corresponds to the position of the bearing seat 1. At this time, the bolt 101 has successfully passed through the flange holes of the outer flange 3 and the inner flange 4, and the gasket and nut can be installed. The whole installation process is more convenient, quick and labor-saving, and it is also convenient for workers to judge whether the bolt 101 and the flange hole are aligned.
