CONSTITUTION:A plurality of blades 3 are radially disposed on the circumference of a sphere 2 which has the center point 6 placed on a rotating rod 1, whereby a universal turbine may be built up. Each of said blades 3 having a pair of pressure receiving faces 7 which are inclined symmetrically with respect to the center plane or the revolution plane in the advancing direction of water or air current in the sectional view. The sections of all the blades are oriented in the same direction with respect to the center of revolution. Rear and front edges of the blade 3 are shaped like arcs of circles which are internally tangent to said pressure receiving faces 7. The part on the sphere 2 whereat the blades 3 are fit is internally reinforced with steel or so and shaped in the form of a flywheel 4, which is attached to the rotating rod 1 by means of spokes 5. This turbine is disposed in parallel with the flowing direction of fluid.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a turbine in a wind or water wheel that is not restricted in the flow direction of the driving fluid.

Traditionally, when designing windmills or water turbines, the direction and strength of the flow of air or water that serve as the driving fluid was considered to be the most important factor, and the design was done assuming that these flows were constant, steady flows. be exposed.

Therefore, in general, in order to extract the maximum kinetic energy of the driving fluid, it is a prerequisite that the turbine be oriented directly in the direction of flow, and a large amount of construction cost is required for the equipment to make this oriented. There was such a problem.

For example, when water is used as the driving fluid, a waterway is installed from a high place to keep the direction and strength of water flow constant, or when air is used as the driving fluid, the turbine is always facing the direction of the wind. Therefore, it is necessary to support the turbine rotatably around a vertical axis, which requires a considerable amount of cost for ancillary equipment other than the turbine device for extracting power.

In view of the above-mentioned problems, the present invention maintains constant rotation in 6 directions even if the flow direction of the driving fluid such as water flow or wind direction changes in the opposite direction, thereby achieving high altitude at low cost. It was created with the aim of obtaining a turbine that can constantly extract natural energy.
A large number of blade bodies each having a pressure-receiving surface formed from a pair of inclined surfaces symmetrically inclined with respect to the rotating surface in the direction of travel are arranged radially from the center of the spherical body on the outer peripheral surface of a spherical body whose center is on the axis of rotation. It is characterized by being extended and fixed at equal intervals.

Next, the present invention will be explained by examples.

FIG. 1 is a vertical projection view of an embodiment of the invention, and FIG.
3 is a horizontal projection view of the figure, FIG. 3 is a sectional view taken along the line ■--■ of FIG. 2, and FIG. 4 is an explanatory diagram showing details of the blade of FIG. 1, FIG. 2, or FIG. 3.

The universal turbine of the present invention includes a rotating shaft rod 1,
It is composed of a sphere 2 whose center is on the rod 1 and a blade 3 extending and fixed on the sphere a, and the rotating shaft rod 1 is pivotally supported by appropriate means, and the rotational energy of the rod 1 is supported by equipment ( (not shown). Further, as shown in FIG. 3, the sphere 2 is fixed on the rotary shaft rod 1 with the center 6 being a point on the axis of the rotary shaft rod 1, and is preferably hollow in order to reduce the moment of inertia. .

Further, the blades 3 are attached to the outer surface of the sphere 2 so as to extend radially from the center 6 at equal intervals on a rotating surface that passes through the center 6 of the sphere 2 and is perpendicular to the axis of the rotating shaft rod 1. There is.

It is formed to have a cross-sectional shape having a pair of pressure-receiving surfaces 7.7 that are symmetrically inclined with respect to the rotational surface (arrow P) around the center plane P°, and all cross-sections are arranged in the same direction with respect to the rotation center. There is. Note that the shapes of the rear edge 8 and front edge 9 of the blade 3 are arcs of inscribed circles of the leek pressure surfaces 7, 7, respectively.

In the above embodiment, the inner surface of the blade 3 attachment part of the sphere 2 is reinforced with steel or the like, and the flywheel 4 is formed with spokes 5.
It is firmly attached to the rotating shaft 1 by.

Further, although the materials used in the above embodiments are plastic, stainless steel, light metal, or a combination thereof, it is desirable that the sphere 2 and the blade 3 be as lightweight as possible.

Next, the operation of this invention will be explained.

In the universal turbine of the present invention, the rotating shaft rod 1 is arranged parallel to the flow direction of the driving fluid.

When the fluid collides with the blade 3, the blade rotates as shown by arrow Q in FIG. 2 due to the pressure difference generated between the front and rear edges of the blade.

Since the cross-sectional shape of the blade is symmetrical, the pressure difference is the same even if the flow of the driving fluid changes in the opposite direction, so the rotation direction is always constant as shown by arrow Q. Therefore, rotational motion in the same direction can always be obtained regardless of the flow direction of the driving fluid. or,
The fluid colliding with the blade 3 is diffused in the radial direction by the sphere 2, so this diffusion increases the flow speed of the fluid,
This improves efficiency.

Since this invention is configured as described above, it is possible to always extract a constant rotational motion regardless of the flow direction of the driving fluid, so there is no need for incidental equipment such as a flow direction conversion device as in the past. It can be installed inexpensively, especially
When extracting rotational energy from wave motion, wind direction or water flow works most effectively because the flow direction changes in the opposite direction.
