2. Description of the Related Art Since a conventional water turbine cannot be assembled and disassembled, it cannot be moved to another place by reducing its size and weight. In addition, since the water turbine is a fixed type that cannot cope with the ebb and flow of the water level, it was necessary to select rivers and places where the water level does not change so as to produce efficient rotational force. For this reason, because the turbine is fixedly installed according to the water level in the season when the torque of the turbine is required, the torque is often produced in a season with an ideal water level, but in other seasons the ideal water level is Since it was not possible to obtain it, it was not possible to utilize the rotational force of the water turbine throughout the four seasons. Also, the effects of daily weather were not negligible.

[0003]

The conventional water turbine has a drawback that it cannot be easily moved to another place because it cannot be assembled and disassembled so that the size cannot be reduced and the weight cannot be reduced. Further, since the water turbine is fixedly installed, there is a drawback that the rotational force is lost due to a change in water level. We have taken up the challenge of overcoming these issues.

By moving up and down the support rod 4 of, the blade 10 captures the hydrodynamic force of the water flow at a moderate water depth and rotates the turbine 1 in a stable state. If you put a float in the support 5, the float will go up and down in parallel with the change of the water level and the float will also go up and down, pushing up the support rod 4 to help adjust the water level of the water turbine 1. This float may be a ball or a bottle, and is used depending on the situation of the water turbine 1. The rotation of the water turbine 1 is transmitted to the flexible shaft by rotating the shaft 3 to rotate the power generator. The water turbine 1 has a free idea and a free structure, and does not need to be captured in FIG. Some turbine main body 2 has a structure and shape that cannot distinguish the shaft 3, wheel 6, ring 7, and buoyancy body 8. There is also a polygonal water turbine 1. There is also a water turbine that has a smooth side surface from the shaft to the outer circumference of the water turbine body 2. Some have a large radius from the shaft to the outer circumference of the turbine body 2, and some have a wider width than the radius. In the turbine main body 2 which does not have a groove for mounting the blade 10, a groove for mounting the blade 10 can be formed. In the turbine main body 2 which does not have a mounting means for mounting the blade 9, the barb 12, the hanging groove 13,

In the parking means, the support rods 4 extending from both ends of the shaft 3 are used as detent rods, and the tip end thereof is fixed to an arbitrary position extended in the air, while being aligned with the top and bottom of the water turbine 1 according to the change of the water level. A float turbine characterized by being able to rotate the turbine 1 in a stable position.

As shown in FIG. 2, the upper portion of the blade plate 9 has blades 10 which are ideal and have a free shape for firmly capturing the hydrodynamic force of the water stream and rotating the water turbine 1. The U-shaped base 9a of the vane plate 9 has a claw 11 as a mounting means at the tip thereof, and the claw 11 is a device fixed by the barb 12 of the turbine main body 2, a hanging groove 13, or the like. . In FIG. 3, the U-shaped base 9 a of the vane plate 9 straddles the buoyancy body 8, and the claw 11 is hung on the barb 12 of the ring 7 to fix the vane plate 9 on the buoyancy body 8.

In FIG. 4, there is a stop hole 14 at the tip of the U-shaped base 9a of the blade plate 9. The stop hole 14 is a device to be fixed by a fixed wart 15 of the turbine main body 2, a fixing hole 16, or the like. As shown in FIG. 5, the U-shaped base 9 a of the vane plate 9 straddles the buoyancy body 8 and fits the fixing hole 14 with the fixing wart 15 of the ring 7 to fix the vane plate 9 on the buoyancy body 8.

As shown in FIG. 6, the U-shaped base 9a of the vane 9 covers the buoyancy rest 8 and the ring 7, and the fixing hole 16 of the vane 9 is aligned with the fixing hole 16 of the wheel 6 and is fastened with a fastener. The buoyant body 8 and the vane plate 9 are fixed on the ring 7. If the buoyancy body 8 is divided, if the number of blades 9 is equal to or more than the number of divisions, the buoyancy body 8 is divided.
Can be fixed around the ring 7 or the wheel 6 all around. Then, the blade 9 is firmly stabilized on the buoyancy body 8.

FIG. 7: The vertically long continuous blades can connect the two water wheels 1 arranged upstream and downstream one round, and can convert the hydrodynamic force of the water in a long basin into rotational energy without waste. . Further, the continuous blades can be individually made into a single blade 9. In the vane plate 9 having no attachment means, the band having the claws is placed on the plate-shaped base 9a, and the claws are returned 12 or hung on the hanging groove 13 to be fixed to the outer periphery of the water turbine body 2. There are various other means for attaching the blade 9, such as an adhesive, a nail, a screw, and a rope. The shape of the continuous blade need not be limited to that shown in FIG.

Buoyancy body 8 which is a fixed ring
The ring 7 and the wheel 6 can be housed in the ring 7 so that they are sandwiched from both sides. In addition to this, even if both sides of the ring 7 can be detached from the wheel 6, or even if only one side of the ring 7 can be detached from the wheel 6, the buoyancy body 8 that is a constant ring is to be housed in the ring 7. Can be done. Fig. 10, Ring 7 with divided circumference
Has a hanging groove 13 and has a mounting portion 17 for mounting on the wheel 6. Since the mounting portion 17 does not straddle the wheel 6, it can be mounted without worrying about the thickness of the wheel 6.

The float turbine described here produces a rotating force efficiently throughout the year while being constantly immersed in a constant depth without being affected by the ebb and flow of the water due to the balance between the weight and buoyancy of the freely shaped turbine 1. Is intended. The shaft 3 of the stopping means of the turbine main body 2 that produces a rotational force includes a rotating shaft and a non-rotating shaft, and a supporting rod 4 that supports this shaft 3.
Is characterized by being a detent rod that moves in accordance with the vertical direction of the water wheel 1. The parking means is on both sides of the water wheel 1, but it may be on one side. This float turbine is composed of a wheel 6, a ring 7, a buoyant body 8 of a freely-shaped turbine 1,
No matter how the blades 9 and blades 10 are divided into pieces, they will not be aligned. This float turbine was made of a material that floats on water. Alternatively, it has a hollow structure that floats in water. Alternatively, the water wheel 1 floats on water by combining a material floating on water and a hollow structure floating on water. Even if the material sinks in water, it becomes a lightweight material that floats on water by providing bubbles. The hollow structure of the water turbine 1 that floats on water may be one room, multiple rooms, or innumerable air bubbles, so it does not matter what material the water wheel 1 is made of. In short, the turbine body 2
The water turbine 1 may have a blade 10 or a blade plate 9 firmly attached to the outer circumference of the blade so that the blade 10 has a water depth that allows the flow force of the flowing water to be captured well, or a rotational force can be produced. The buoyancy is not limited to the buoyancy body 8, and it goes without saying that the wheel 6, the ring 7, the blades 9, the blade plate 10, etc. may have buoyancy.

[0018]

According to the present invention, since the conventional water turbine is fixedly installed in accordance with the water level of the season when the rotating force is required, it can produce the rotating force well in the season when the ideal water level exists. Since the ideal water level could not be obtained in the seasons, it was not possible to produce the rotational force of the water turbine throughout the four seasons, whereas the material that floats on water for the first time or a hollow structure with buoyancy was adopted. For this reason, we have established a new system that creates a stable balance between the buoyancy and weight of the water turbine 1 and allows the ideal rotational force to be produced by submerging the water flow moderately throughout the four seasons with different water levels. Then, the water turbine 1 is lightened, divided, and assembled to facilitate movement and installation. The float turbine of the present invention floats while being properly immersed in the flow due to the balance between the buoyancy and weight of the turbine 1.
There is no longer a need for a heavy turbine pedestal that counters the hydrodynamics of the water stream as the turbine is heavier and heavier. The parking means, which replaces the pedestal, has support rods 4 extending from both ends of the shaft 3 that move up and down in accordance with the vertical direction of the water turbine to keep the water turbine 1 in a stable posture and rotate while holding it against the water flow. A float turbine characterized by a simple device that is not intended to support the weight of the turbine 1.
