Abstract
Description
Technical Field
[0001] This invention relates to the field of wind power generation technology, and in particular to a wind power generation tower base. Background Technology
[0002] Wind energy is the kinetic energy generated by the movement of large amounts of air across the Earth's surface. Due to differences in temperature and water vapor content in the air caused by varying solar radiation across different areas of the ground, air pressure varies. High-pressure air flows horizontally towards low-pressure areas, forming wind. Wind energy resources are determined by wind energy density and the annual cumulative number of usable wind hours. Wind energy density is the power of wind available per unit windward area, and it is directly proportional to the cube of the wind speed and the air density. A wind turbine tower is the support structure for wind power generation. In wind turbine generators, it primarily provides support and absorbs vibrations. Therefore, a suitable wind turbine tower base is urgently needed to provide adequate support.
[0003] However, most existing wind turbine tower bases are welded to the bottom of the tower. However, the bases are relatively large and easily damaged during transportation, which compromises their support for the tower, shortens their service life, and can easily cause unnecessary economic losses and poor performance. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing wind power tower bases, which are mostly welded to the bottom of the tower. However, the bases are large and easily damaged during transportation, which compromises their support for the tower, shortens their service life, and causes unnecessary economic losses and poor performance. Therefore, this invention proposes a wind power tower base.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A wind power generation tower base includes a base, a circular groove is formed on the top side of the base, a placement groove is formed on the bottom inner wall of the circular groove, four limiting grooves and four locking grooves are formed on the bottom inner wall of the circular groove, a base plate is provided on the bottom side of the placement groove, a tower body is fixedly welded to the top side of the base plate, a sleeve is fixedly welded to the outer side of the tower body, and the bottom side of the sleeve is fixedly welded to the top side of the base plate.
[0007] The positioning mechanism includes four fixed seats, all of which are fixedly welded to the tower body. The fixed seats are located in the corresponding limiting grooves. Each of the four fixed seats has a threaded groove, and each of the four threaded grooves has a threaded rod threadedly connected to it. A circular cover plate is placed on the bottom inner wall of the circular groove.
[0008] The stabilizing mechanism includes four stabilizing rods arranged at equal intervals. The bottom ends of the four stabilizing rods are rotatably mounted on the top side of the base. Multiple connecting plates are fixedly welded to the tower body. The same first bolt is provided on two corresponding connecting plates. The stabilizing rods are movably mounted on the two corresponding connecting plates through the first bolt.
[0009] In a preferred embodiment, the base has four equally spaced circular holes, and the threaded rod is located in the corresponding circular holes, which facilitates the disassembly of the threaded rod. This allows the threaded rod to be easily disassembled while providing stable positioning for the fixed seat, and the base does not affect the disassembly of the threaded rod.
[0010] In a preferred embodiment, a plurality of second bolts are provided on the top side of the base plate. The base plate is installed on the bottom inner wall of the placement groove by the plurality of second bolts, which facilitates the disassembly and installation of the base plate. This allows the base plate to provide stable support for the tower body and prevent the tower body from tilting due to force majeure factors such as earthquakes, thus avoiding unnecessary economic losses and safety threats.
[0011] In a preferred embodiment, the threaded rod is provided with a set of external threads, and the threaded groove is provided with a set of internal threads. The external threads and the internal threads mesh with each other, making the installation of the tower body more stable and reducing the weight borne by the base plate, thereby achieving multiple effects of stabilizing the tower body.
[0012] In a preferred embodiment, a plurality of fixing plates are fixedly welded to the top side of the base, and the same fixing shaft is fixedly welded to the side of two corresponding fixing plates that are close to each other. The stabilizing rod is rotatably mounted on the corresponding fixing shaft, so that the rotation of the stabilizing rod is more stable, and the stabilizing rod provides stable support for the tower body.
[0013] In a preferred embodiment, four equally spaced support rods are fixedly welded to the top side of the annular cover plate. Each of the four support rods has a limit plate fixedly welded to its top. The limit plate contacts the corresponding stabilizing rod, thus limiting the position of the annular cover plate. During use, the annular cover plate can only be removed when the tower body is disassembled, which increases the sealing of the placement groove, prevents rainwater erosion, and prevents long-term corrosion of the equipment in the placement groove caused by external factors, thereby affecting the service life of the equipment.
[0014] In a preferred embodiment, four equally spaced locking rods are fixedly welded to the bottom side of the annular cover plate. The locking rods engage with the corresponding locking slots, which facilitates the installation of the annular cover plate, making the installation process faster and more efficient, reducing the workload of workers, and improving installation efficiency.
[0015] In a preferred embodiment, a first sealing cylinder is fixedly bonded to the sleeve, and a second sealing cylinder is fixedly bonded to the inner wall of the annular cover plate. The first sealing cylinder and the second sealing cylinder are in contact, so that the placement groove is in a sealed state. When the first sealing cylinder and the second sealing cylinder age, the first sealing cylinder and the second sealing cylinder need to be replaced in time to avoid unnecessary losses.
[0016] In this invention, a wind power tower base is provided. When the sleeve body needs to be installed, the tower body is first lifted by a crane, the base plate is placed in the placement groove, the fixing seat is placed in the corresponding limiting groove, the base plate is installed in the placement groove by multiple second bolts, the four threaded rods are rotated so that the threaded rods are screwed into the corresponding threaded grooves, the annular cover plate is installed on the circular groove, so that the locking rod is engaged with the corresponding locking groove, the first sealing cylinder and the second sealing cylinder are in close contact, so that the placement groove is in a sealed state, the four stabilizing rods are rotated so that the top of the stabilizing rod is installed on the tower body by the first bolt, and the stabilizing rod limits the annular cover plate by the limiting plate, so as to provide stable support for the tower body.
[0017] In this invention, the wind power generation tower base can be disassembled simply by first removing the first bolt to prevent the stabilizing rod from supporting the tower body, then removing the four threaded rods, moving the circular cover plate upwards, and finally removing the second bolt. The operation is simple.
[0018] The present invention has a reasonable structural design, which can provide stable support for the tower. The base and the tower can be disassembled, so there will be no damage during transportation. It is easy to maintain, has good performance, and high work efficiency, and is worth promoting and using.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0028] Reference Figures 1-7 One embodiment of this solution is a wind power generation tower base, including a base 1. A circular groove 2 is provided on the top side of the base 1. A placement groove 3 is provided on the bottom inner wall of the circular groove 2. Four limiting grooves 4 and four locking grooves 5 are provided on the bottom inner wall of the circular groove 2. A base plate 6 is provided on the bottom side of the placement groove 3. A tower body 7 is fixedly welded to the top side of the base plate 6. A sleeve 8 is fixedly welded to the outside of the tower body 7. The bottom side of the sleeve 8 is fixedly welded to the top side of the base plate 6.
[0029] The positioning mechanism includes four fixed seats 9, which are all fixedly welded to the tower body 7. The fixed seats 9 are located in the corresponding limiting grooves 4. Each of the four fixed seats 9 has a threaded groove 10, and each of the four threaded grooves 10 is threaded with a threaded rod 11. A circular cover plate 13 is placed on the bottom inner wall of the circular groove 2.
[0030] The stabilizing mechanism includes four equally spaced stabilizing rods 18. The bottom ends of the four stabilizing rods 18 are rotatably mounted on the top side of the base 1. Multiple connecting plates 19 are fixedly welded onto the tower body 7. The same first bolt 20 is provided on two corresponding connecting plates 19. The stabilizing rods 18 are movably mounted on the corresponding two connecting plates 19 through the first bolt 20.
[0031] Reference Figure 1 In this embodiment, multiple fixing plates 16 are fixedly welded to the top side of the base 1, and the same fixing shaft 17 is fixedly welded to the side of two corresponding fixing plates 16 that are close to each other. The stabilizing rod 18 is rotatably mounted on the corresponding fixing shaft 17, so that the rotation of the stabilizing rod 18 is more stable, and the stabilizing rod 18 plays a stable supporting role for the tower body 7.
[0032] Reference Figure 1 In this embodiment, four equally spaced support rods 21 are fixedly welded to the top side of the annular cover plate 13. The top of each of the four support rods 21 is fixedly welded with a limiting plate 22. The limiting plate 22 contacts the corresponding stabilizing rod 18 and limits the position of the annular cover plate 13. During use, the annular cover plate 13 can only be removed when the tower body 7 is disassembled, which increases the sealing of the placement groove 3, avoids rainwater erosion, and prevents long-term use from causing corrosion to the equipment in the placement groove 3 due to external factors, thus affecting the service life of the equipment.
[0033] Reference Figure 2 In this embodiment, a plurality of second bolts 23 are provided on the top side of the base plate 6. The base plate 6 is installed on the bottom inner wall of the placement groove 3 by the plurality of second bolts 23, which facilitates the disassembly and installation of the base plate 6, so that the base plate 6 provides stable support for the tower body 7, preventing the tower body 7 from tilting due to force majeure factors such as earthquakes, thus avoiding unnecessary economic losses and safety threats.
[0034] Reference Figure 2 In this embodiment, the threaded rod 11 is provided with a set of external threads, and the threaded groove 10 is provided with a set of internal threads. The external threads and internal threads mesh with each other, making the installation of the tower body 7 more stable, while reducing the gravity borne by the base plate 6, thus achieving the effect of multiple stabilization of the tower body 7.
[0035] Reference Figure 3 In this embodiment, four equally spaced locking rods 15 are fixedly welded to the bottom side of the annular cover plate 13. The locking rods 15 are engaged with the corresponding locking grooves 5, which facilitates the installation of the annular cover plate 13, making the installation process faster and more efficient, reducing the workload of workers, and improving installation efficiency.
[0036] Reference Figure 4In this embodiment, a first sealing cylinder 12 is fixedly bonded to the sleeve 8, and a second sealing cylinder 14 is fixedly bonded to the inner wall of the annular cover plate 13. The first sealing cylinder 12 and the second sealing cylinder 14 are in contact, so that the placement groove 3 is in a sealed state. When the first sealing cylinder 12 and the second sealing cylinder 14 age, they need to be replaced in time to avoid unnecessary losses.
[0037] Reference Figure 5 In this embodiment, the base 1 has four equally spaced circular holes, and the threaded rod 11 is located in the corresponding circular holes, which facilitates the disassembly of the threaded rod 11. This allows the threaded rod 11 to be easily disassembled while stabilizing and limiting the fixed seat 9, so that the base 1 does not affect the disassembly of the threaded rod 11.
[0038] Working principle: When the tower body 7 needs to be installed, the tower body 7 is first lifted by a crane, the base plate 6 is placed into the placement groove 3, the fixing seat 9 is placed in the corresponding limiting groove 4, and the base plate 6 is installed in the placement groove 3 by multiple second bolts 23. The four threaded rods 11 are rotated so that the threaded rods 11 are screwed into the corresponding threaded grooves 10, and the annular cover plate 13 is then installed. Installed on the circular groove 2, the locking rod 15 is engaged with the corresponding locking groove 5, and the first sealing cylinder 12 and the second sealing cylinder 14 are in close contact, so that the placement groove 3 is in a sealed state. Rotate the four stabilizing rods 18 so that the top of the stabilizing rod 18 is installed on the tower body 7 through the first bolt 20. The stabilizing rod 18 limits the circular cover plate 13 through the limiting plate 22, so as to provide stable support for the tower body 7. When it is necessary to disassemble the tower body 7, simply remove the first bolt 20 so that the stabilizing rod 18 does not support the tower body 7, then remove the four threaded rods 11, move the circular cover plate 13 upward, and then remove the second bolt 23.
