Description

[Detailed description of the invention] This invention relates to a blade wheel suitable for obtaining motive power by utilizing natural energy such as wind and tidal currents, which are wide flows, and in particular, the invention relates to a blade wheel suitable for obtaining motive power by utilizing natural energy such as wind and tidal currents. It is formed on a twisting surface so that it always operates smoothly.

An example of a blade wheel that is pivoted in the air or in the sea and rotates by directly receiving the wind and tidal forces that flow over a wide range is the one shown in Figure 2, which was devised by the applicant earlier. horizontal axes 2 that are perpendicular to each other and slightly separated vertically from the vertical axis 10;
0, 20', 30, 30' are rotatably mounted in several stages up and down, and two left and right vanes 20a, 20b, 20a', 20b', 30 are arranged orthogonally to each horizontal axis.
a, 30b, 30a', 30b' are each fixedly installed, and the blade plate 20 receives the flow in the direction of the arrow in the figure.
Wing plates 20b, 3 on the return side with respect to a, 30a
0b are both substantially horizontal to reduce resistance to flow as much as possible.

In the case shown in Fig. 2 above, the resistance of the return side blades has been reduced, but the rotational force is slightly uneven because the blades, which are located in a cross shape when viewed from above, act as receiving surfaces alternately. This is disadvantageous for wind and tidal power, whose flow direction tends to change constantly.

In contrast, this invention eliminates the above-mentioned drawbacks by assembling the blades serving as receiving surfaces into one twisted concave curved surface, and an embodiment of this invention will be described with reference to FIG. Then, 1 is a vertical shaft which is a driving shaft, and a set of two horizontal shafts 2, 2', 3, 3', 4 pass through this vertical shaft 1 and are slightly separated from each other vertically and intersect in a cross shape. , 4', 5, 5' are installed in several stages by twisting them little by little to one side, and these horizontal shafts have blade plates 2a, 2b, 2a', 2 with the vertical shaft 1 in between.
b', 3a, 3b, 3a', 3b', 4a, 4b, 4
a', 4b', 5a, 5b, 5a', and 5b' are fixed to be orthogonal to each other. These blades are formed by bending a substantially rectangular plate at its diagonal so that the side attached to the horizontal axis and the corresponding side are non-parallel, and the corresponding side is the side of the blade located below. It partially overlaps, forming a series of upper and lower twisting surfaces. Note that 6... is the lowest wing plate 5a, 5b,
This is a stopper that supports 5a' and 5b'.

This invention has the above structure, so that when receiving water flow in the direction of the arrow in Fig. 1, the blades 2a, 3a,
The lower edges of the blades 4a and 5a overlap the upper edge of the lower blade from the front, forming a series of twisted curved surfaces, and the blades 2b, 3b, 4b, and 5b on the opposite side of these blades are in a nearly horizontal state and flow of water. resistance to is reduced. In this way, since the receiving surface is always formed into the above-mentioned twisted curved surface, the degree of pressure receiving in the direction of water flow is constant, smooth rotational force is obtained, and it is suitable for use in power generation and the like. Furthermore, since the horizontal shafts are separated vertically a little and each passes through the vertical shaft as a single shaft, a robust device can be obtained.
