Abstract
Description
Technical Field
[0001] The invention relates to the field of wind power generation, in particular to a high-stability and high-safety frame for multi-axis and multi-layer wind power generation. Background Art
[0002] Wind power generation is a renewable energy source. It will exist as long as the earth, the sun and the air exist. However, wind energy is unstable, non-storable and dispersed. If people want to use wind energy, they can either convert it into mechanical energy or convert it into mechanical energy and then convert it into electrical energy. To use wind energy to generate electricity, wind turbines must be used. Currently, the world's wind turbines are mainly horizontal and vertical. Most of these two types of wind turbines are single-layer single-axis generators placed on a single column. This causes most of the weight of the wind turbine to be placed on the top of the single column. Therefore, the single column constitutes a large part of the cost of the generator, and A single column that is top-heavy and foot-light is bound to cause a safety hazard. For the sake of safety, it is imperative to reduce the top weight. This creates a contradiction. Wind energy is dispersed and unstable. In order to obtain more wind energy, the shaft must be extended and more blades must be added. However, for safety reasons, this has to be reduced due to compromise. Moreover, although the shaft is made of steel and has a high strength, a shaft that is too long will be soft like noodles and bend. If placed horizontally, it will droop at both ends, and if placed vertically, the head will swing. As the shaft requires extremely high stability, sagging and swinging are obviously unsafe and unfeasible. Therefore, the technicians here provide a safer and more reliable frame structure to solve the problems raised in the above background. Summary of the invention
[0003] The purpose of the present invention is to provide a safer and more reliable wind power generation frame to solve the problems of extending the rotating shaft, increasing the number of rotating shafts, and increasing the number of fan blades to capture more wind energy, improve land and space utilization, and achieve a higher wind energy conversion rate frame structure.
[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: It is well known that the four-door column structure conforms to the safety logic of the building. Compared with the single column, the four-door column can share the force received by the building on the four columns regardless of the direction of the force, thereby avoiding the risk of collapse caused by excessive or uneven force.

DETAILED DESCRIPTION
[0015] See also Figure 1~Figure 3 A four-door column frame for wind power generation, comprising three rotating shafts (1), corner supports (2), composite columns (3), cage-type impellers (4), rotating shaft straightening beams (5), rotating shaft straightening bearings (6), rotating shaft hangers (7), rotating shaft hanging bolts (8), hanging bearings (9), composite column foundations (10), sleeve bearing seat foundations (11), column connecting beams (12), sleeve bearing seats (13), and middle section connecting beams (14). First, four composite columns (3) are erected on the composite column foundation (10) in four directions to form a tetrahedron frame, and a column connecting crossbeam (12) is provided at the top thereof, so as to form a frame structure with four doors. A rotating shaft hanger (7) is provided in the middle section of three of the crossbeams, and a hanging bearing (9) and a rotating shaft hanging bolt (8) are provided in the hanger. The top of the rotating shaft passes through the hanging bearing (9) and is connected to the rotating shaft hanging bolt (8) by threads. There are three rotating shafts (1) on three sides of the tetrahedron, and a plurality of middle connecting crossbeams (14) are provided on the remaining side according to the height of the frame to enhance the overall strength and stability of the frame. The same number of cage impellers (4) are hung on each rotating shaft in turn. The lower end of the rotating shaft (1) is connected to the rotating shaft extending from the sleeve bearing seat (13), and the sleeve bearing seat (13) is fixed on the sleeve bearing seat foundation (11). In order to prevent the rotating shaft from swinging, the cage impeller (4) and A shaft centering crossbeam (5) is provided in the middle of the shaft between the sleeve bearing seats (13), and a shaft centering bearing (6) is provided in the middle of the shaft centering crossbeam (5). The shaft passes through the shaft centering bearing (6) and is butted against each other up and down, thus forming a four-door column frame for wind power generation. An angle support (2) is provided at the connection between the top column and the crossbeam of the frame to enhance the stability and strength of the overall structure of the frame. Since the three shafts are suspended on the three faces of the tetrahedron, when the impeller is suspended, the added weight has a partial function of a damper. No matter how the overall frame tends to tilt, there is always a shaft to balance it. In this way, the overall frame is more secure and stable. Since the shaft is suspended, no matter how long the shaft is, the shaft always remains perpendicular to the ground and there is no need to worry about the shaft bending due to excessive length. In this way, an extra-long shaft can be obtained to suspend more impellers, thereby capturing more wind energy.
