Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to a wind power generation rotating platform. Background Technology

[0002] Wind power generation is a renewable energy technology that converts wind energy into electricity. It is clean, environmentally friendly, and sustainable, and occupies an important position in the global energy structure. The process involves suspending a support cylinder at a high altitude, then mounting a wind turbine on the cylinder. The power output end of the turbine connects to the power input end of a gearbox inside the cylinder, which transmits power to a generator, thus converting wind energy into electricity. The drive shaft at the turbine's power output end is rotatably connected to the cylinder primarily through bearings. This rotatable connection is located on the end wall of the cylinder, which provides the main support for the drive shaft. Since the power input end of the drive shaft, i.e., the blade end of the turbine, is often quite heavy, it has a significant tendency to overturn. The torque generated by this overturning tendency acts mostly on the end wall of the cylinder, increasing the risk of end wall deformation. Furthermore, the extended drive shaft, connected to the gearbox, also makes the drive shaft prone to deflection. Utility Model Content

[0003] This utility model provides a wind power generation rotary platform, which, by improving the existing wind power generation rotary platform, can further prevent the risk of deformation of the end wall of the mounting cylinder. At the same time, the improved multi-point support for the drive rotor can also prevent the drive rotor from bending during use due to single-point support.

[0004] The technical problem solved by this utility model is achieved by the following technical solution:

[0005] This utility model provides a wind power generation rotating platform, including a mounting cylinder for providing support, a gearbox inside the mounting cylinder, and a wind turbine outside the mounting cylinder with its drive rod's power output end connected to the gearbox's power input end. The wind turbine's drive rod is rotatably connected to the end wall of the mounting cylinder via bearings. A longitudinal vertical wall parallel to the end wall is integrally formed on the inner side wall of the mounting cylinder, and the longitudinal vertical wall is also rotatably connected to the drive rod via bearings.

[0006] Preferably, there are multiple longitudinal vertical walls, and all of the multiple longitudinal vertical walls are rotatably connected to the drive rod through bearings.

[0007] Preferably, there are two longitudinal vertical walls, which are an upper support integrally formed with the upper part of the inner side wall of the mounting cylinder and a lower support integrally formed with the lower part of the inner side wall of the mounting cylinder.

[0008] Preferably, the longitudinal vertical wall is a ring support extending from the inner wall of the mounting cylinder towards the center.

[0009] Preferably, the longitudinal vertical wall has perforations for airflow to pass through.

[0010] Preferably, the mounting cylinder has heat dissipation holes.

[0011] The beneficial effects of this utility model are: by improving the connection between the existing mounting cylinder and the drive rod, the drive rod can be supported at multiple points, preventing the drive rod from deflecting.

[0012] By setting a rotatable connection between the longitudinal vertical wall and the inner wall of the mounting cylinder, the load on the end wall of the mounting cylinder can be reduced, preventing the risk of end wall deformation. Attached Figure Description

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0026] refer to Figures 1-3 This utility model provides a wind power generation rotating platform, which is used in wind power generation equipment, such as... Figures 1 to 3 As shown, the wind power generation equipment includes a support cylinder 1, a mounting cylinder 2, and a wind turbine 3. The mounting cylinder 2 is located at the top of the support cylinder 1, and the wind turbine 3 is located on one side of the end wall 201 of the mounting cylinder 2. The wind turbine 3 has a drive rod 6 as the output end of the driving force. The power output end of the drive rod 6 passes through the end wall 201 of the mounting cylinder 2 and is connected to a gearbox 4 inside the mounting cylinder 2. The gearbox 4 mainly converts the low speed of the drive rod 6 into high speed power and then transmits it to the generator 5 inside the gearbox 4. The generator 5 inside the gearbox 4 converts mechanical energy into electrical energy. The above is the working principle of existing wind power generation equipment. Other aspects are not related to this utility model. The details of the part will not be elaborated here. The part closely related to this utility model is that the drive rod 6 of the wind turbine 3 passes through the end wall 201 of the mounting cylinder 2 and is connected to the end wall 201 by a bearing (the first bearing 77 in the figure). Since the wind turbine 3 has a large mass, the existing drive rod 6 near the wind turbine 3 is only supported by the end wall 201 of the mounting cylinder 2, which is prone to deformation of the end wall 201. At the same time, the drive rod 6 extends from the wind turbine 3 to the gearbox 4, which is a long distance. Therefore, it is easy for the drive rod 6 to bend if it is only supported by one support point (the bearing position of the end wall 201).

[0027] This utility model mainly improves upon the following aspects, such as Figure 4 and Figure 5As shown, to overcome the problems existing in the prior art, specifically, a wind power generation rotating platform includes a mounting cylinder 2 for providing support, a gearbox 4 inside the mounting cylinder 2, and a wind turbine 3 outside the mounting cylinder 2, with its drive rod 6 connected to the power input end of the gearbox 4. The drive rod 6 of the wind turbine 3 is rotatably connected to the end wall 201 of the mounting cylinder 2 via bearings. A longitudinal vertical wall parallel to the end wall 201 is integrally formed on the inner wall 203 of the mounting cylinder 2. The longitudinal vertical wall is connected to the drive rod 6. The drive rod 6 is also rotatably connected via bearings. By setting longitudinal vertical walls inside the mounting cylinder 2 and rotatably connecting these longitudinal vertical walls to the drive rod 6 via bearings, multi-point support for the drive rod 6 can be achieved, thus preventing the drive rod 6 from deflecting. Since the longitudinal vertical walls are integrally formed with the inner wall 203 of the mounting cylinder 2, the inner wall 203 of the mounting cylinder 2 can share some of the tilting force generated during the tilting of the wind turbine 3, reducing the load on the end wall 201 of the mounting cylinder 2 and reducing the risk of deformation of the end wall 201 of the mounting cylinder 2. Specifically, multiple longitudinal vertical walls can be set, and multiple longitudinal vertical walls can be rotatably connected to the drive rod 6 via bearings, which can improve the anti-deflection effect of the drive rod 6 and further prevent the end wall 201 from bearing too much load.

[0028] Furthermore, such as Figure 5 , Figure 9 and Figure 10 As shown, there are two longitudinal vertical walls, both of which are connected to the drive rod 6 via bearings. For easy identification, see attached... Figure 5 In the middle, the bearing at position 201 on the end wall is the first bearing 7, and the bearings at the two longitudinal vertical wall positions are the second bearing 8 and the third bearing 9, respectively. The two longitudinal vertical walls can be as follows: Figure 10 As shown, the upper support 14, which is integrally formed with the upper part of the inner wall 203 of the mounting cylinder 2, and the lower support 13, which is integrally formed with the lower part of the inner wall 203 of the mounting cylinder 2, can distribute the load on the end wall 201 to the mounting cylinder 2 through the upper support 14 and the lower support 13, and it will not cause a sealed area to be formed inside the mounting cylinder 2, so the internal air flow is better and the heat dissipation effect is better.

[0029] Furthermore, such as Figure 6 and Figure 7As shown, the longitudinal vertical wall is an annular support extending from the inner wall 203 of the mounting cylinder 2 towards the center. The two annular supports can contact the inner wall of the mounting cylinder 2 evenly in the circumference, which improves the load sharing effect of the end wall 201. The two annular supports are the first annular support 10 and the second annular support 11. Since the first annular support 10 and the second annular support 11 both abut against the inner wall of the mounting cylinder 2, multiple sealing areas will be formed between the mounting cylinders 2. Since the annular supports form a sealing area inside the mounting cylinder 2, its heat dissipation effect is poor.

[0030] Furthermore, such as Figure 6 and Figure 7 As shown, in order to allow airflow between the sealed areas formed inside the mounting cylinder 2 and achieve heat dissipation, perforations are provided on the longitudinal vertical wall for airflow to pass through. The airflow perforations 12 can increase the gas flow inside the mounting cylinder 2, thereby increasing the heat dissipation effect.

[0031] Furthermore, such as Figure 8 As shown, the mounting cylinder 2 is provided with a heat dissipation through hole 202. The heat dissipation through hole 202 is used to realize the air exchange between the inside and outside of the mounting cylinder 2, which is beneficial to the heat dissipation of the bearing position.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above-described embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
