Description

Technical Field

[0001] The invention relates to wind power generation, in particular to a wind power generation cage impeller. Background Art

[0002] Wind energy is a renewable natural resource. As long as there is the sun, the earth and air, it will exist forever. Existing wind power generation mainly consists of two technologies: horizontal axis and vertical axis. Most of these two technologies are single-axis single-layer blades. Because the single-axis generator and blades are placed on a single column, it is bound to cause a top-heavy situation. The single column not only has great safety hazards, but also consumes a lot of costs on the single column for safety reasons. In addition, considering the bearing capacity of the single column, the weight of the generator and blades is limited. However, wind energy is dispersed and more blades are needed to collect and capture more wind energy. Because the weight is limited, more blades and It becomes very difficult to build more generators, and because the single column is top-heavy, the existing wind turbines have poor typhoon resistance and frequent collapse accidents. In order to solve the problem of too high center of gravity and improve the ability to capture wind energy, I have designed a tower-type combined with longitudinal wind power generation system, which can also be called a multi-axis multi-layer wind turbine. Due to the use of a four-door column structure and the grounding of components such as generators, the top-heavy situation is avoided. Because the stability and safety are greatly improved under the four-door column structure, the fan blades have more room to play. Therefore, I provide a cage-type impeller for a wind turbine that can be arbitrarily combined. Summary of the invention

[0003] The purpose of the present invention is to provide a wind turbine fan blade that is designed to be flexible in transportation and installation, and can be combined at least three or more in any way to capture more wind energy. Whenever the length of the rotating shaft increases to the same length as the height of the wind turbine impeller, three impellers can be installed and suspended at the same time. In this way, the number of fan blades can be easily increased, and the scattered wind is transmitted to the rotating shaft through a large number of impellers, and then the energy is concentrated through multiple rotating shafts for power generation. Therefore, it is possible to greatly improve the wind energy conversion rate and land utilization rate within a certain spatial range, and change the wind power generation mode of fighting alone into a team cooperation mode. In order to achieve the above purpose, the present invention provides the following technical solutions.

[0004] A wind power generation cage impeller is mainly composed of two large concentric circles and two small concentric circles. The two large concentric circles are called impeller outer rings (1), and the two small concentric circles are called impeller inner rings (12). They are connected and fixed to the inner ring base (9) by inner ring bolt holes (13) and base bolts (8). Then, the oblique support (4) and the transverse support inner and outer ring connecting pieces (10) are connected between the impeller outer ring (1) and the inner ring base (9). The inner ring base (9) is welded to the two ends of the impeller through-tube (5). The purpose of the through-tube is to pass the impeller as a whole on the rotating shaft. Because of the impeller through-tube, the impeller forms an independent entity, which is very convenient to install and transport and relatively low in cost.

[0005] A wind power generation cage-type impeller, wherein two impeller outer rings (1) are fixedly mounted with a plurality of positioning connection columns (11), the purpose of which is to increase the strength of the impeller and limit the position between the two impellers.

[0006] A wind power generation cage impeller, wherein the impeller outer ring (1) is provided with a plurality of angle codes (7) for connecting fan blades, and the upper and lower angle codes are opposite to each other in pairs and are used to connect arc-shaped fan blades (2).

[0007] The reason why it is called an impeller is not only because its appearance resembles a wheel, but also because the number of high-density curved fan blades (2) installed far exceeds ten, which resembles a bird cage. As the diameter of the impeller increases, the number of blades will also increase accordingly. This is because the closer the distance between the blades, the shorter the time for wind power relay, thereby ensuring the continuity of force and the possibility of increasing the rotation speed.

[0008] A cage-type impeller of a wind turbine generator, wherein the impeller through-tube (5) is also provided with a tension bolt (6), the purpose of which is that after the impeller is installed on the rotating shaft, the tension bolt (6) can be tightened to fix the impeller and the rotating shaft together, so that when the impeller is rotated by the wind, the wind force is transmitted to the rotating shaft, and when the rotating shaft is long enough to hang more impellers, more wind energy can be captured.

[0009] A cage-type impeller of a wind turbine generator, wherein the impeller through-tube (5) has inner ring connecting bases (9) fixedly connected at both ends, and base bolts (8) are provided on the inner ring base.

[0010] A cage-type impeller of a wind turbine generator, wherein the impeller inner ring (12) is connected to the impeller outer ring (1) via an inner and outer ring connecting piece (10), and is connected to the inner ring connecting base (9) via inner ring bolt holes (13) and base bolts (8).

[0011] An inner and outer ring connecting member (10) of a cage-type impeller of a wind turbine generator is provided with an inclined support (4), the other end of the inclined support (4) being connected to an impeller through-tube (5).

[0012] A further solution of the wind power generation cage impeller is to decompose the entire impeller into three or four equal parts for the convenience of transportation and installation. The two ends of the two impeller outer rings (1) of each equal part are connected to the two ends of the equally divided impeller inner ring (12) through inner ring connectors (10), and the two impeller outer rings (1) are connected through impeller positioning connection columns (11), blade connection angle codes (7) and arc-shaped blades (2) to form a transition component.

[0013] A wind power generation cage impeller, the impeller is evenly decomposed into three or four equal parts, the inner and outer ring connecting parts (10) of the transition component are provided with fastening bolts (3) and inclined supports (4), the two ends of the inclined supports (4) are connected to the inner and outer ring connecting parts (10) of the impeller through-tube (5), and the adjacent inner and outer ring connecting parts (10) are connected by fastening bolts (3), so that when several transition components are connected to each other, and the inner ring connecting base (9) is connected to the corresponding impeller inner ring (12) through the inner ring bolt hole (13) on the impeller inner ring (12), an independent and complete cage impeller is formed, and it is connected to the impeller through-tube (5) through the inclined supports (4), so that the overall shape can be kept stable and not deformed under the action of gravity.

[0015] See also Figure 1~Figure 6The present invention discloses a cage-type impeller of a wind turbine generator, comprising 1 an impeller outer ring, 2 arc-shaped blades, 3 fastening bolts, 4 oblique supports, 5 impeller through-tubes, 6 tensioning bolts, 7 blade connection angle codes, 8 base bolts, 9 inner ring bases, 10 inner and outer ring connectors, 11 impeller positioning connection columns, 12 impeller inner rings, and 13 inner ring bolt holes. First, an impeller through-tube 5 is provided, and inner ring connection bases 9 are welded at both ends of the impeller through-tube 5. The base and the through-tube are concentric circles. The inner ring connection base 9 is provided with base bolts 8. The impeller through-tube 5 is provided with a base bolt 8. A tension bolt 6 is also provided. Since the torque force is equal to the force multiplied by the lever arm, the radius of the impeller can be large or small according to the requirements. An impeller with a large diameter cannot pass through a narrow physical space, and an impeller with a large diameter is not convenient for vehicle transportation. Therefore, the remaining part of the impeller is equally divided into three or four equal parts of the transition assembly. The upper and lower impeller inner rings 12 and the upper and lower impeller outer rings 1 are simultaneously decomposed into three or four equal parts, and then connected to form a transition assembly through four inner and outer ring connectors 10 and impeller positioning connecting columns 11, such as Figure 4 Figure 5 Figure 6 As shown, a plurality of blade connection angle codes 7 are provided at relative positions of the upper and lower impeller outer rings 1, and the two ends of the arc-shaped blade 2 are respectively connected to the blade connection angle code 7, and each arc-shaped blade 2 is installed in the same direction. The inner and outer ring connecting pieces 10 are also provided with oblique supports 4 and fastening bolts 3, and the impeller inner ring 12 is provided with base bolt holes 13. When necessary, the base bolts 8 are respectively connected through the inner ring bolt holes 13 to align the upper and lower impeller inner rings 12 with the upper and lower inner ring bases 9, and the two ends of the oblique supports 4 are respectively connected to the inner and outer ring connecting pieces 10 and the impeller through-tube 5. Then, the inner and outer ring connectors (10) of the adjacent transition components are connected together in sequence by fastening bolts 3. After all the impellers are assembled, they look like a round bird cage. Because there is an impeller through-tube 5, the assembled cage impeller is an independent component and can be strung on the shaft from the bottom in sequence according to the length of the shaft. The length of the shaft determines the number of impellers that can be hung. Since there are at least three shafts, the number of impellers can be multiplied as the length of the shaft increases. Because the number of impellers is large, it is possible to capture wind energy and improve the utilization rate of land and space.
