More particularly, the present invention relates to a rotating device and a rotating force extracting device using a floating body pushing-up force generated by maintaining an upper surface of a floating body arranged in water at atmospheric pressure.

[0002]

2. Description of the Related Art As a device for obtaining a rotational force by using a buoyant force acting on a floating body arranged in water, for example, a device shown in FIG. 14 has been conventionally proposed. The apparatus shown in FIG. 14 winds a floating body connecting belt 34 formed by connecting a large number of cylindrical floating bodies 34a with a string body 34b around a pair of pulleys 32 and 33 arranged outside a water tank 31. The structure is such that a part of 34 is inserted through the water tank 31. In this conventional apparatus, the floating body connecting belt 34 is rotated counterclockwise in the figure by the buoyancy acting on the floating body 34a 'located in the water tank 31, thereby rotating the pulleys 32 and 33, thereby taking out the rotational force. Is expected.

[0003]

However, in the above-mentioned conventional apparatus, it is necessary to make the floating body 34a enter the water tank 31 from the bottom wall by overcoming the water pressure, and the force required for this is larger than the sum of the buoyancy. However, in reality, it is impossible to rotate, and the rotational force cannot be taken out.

[0004] The present invention has been made in view of the above-mentioned conventional situation, and instead of making it enter into the water tank as in the above-mentioned conventional apparatus, by using the force pushed out of the water tank by water pressure, It is an object of the present invention to provide a device that enables rotation of a floating body connecting belt and a rotational force extracting device that enables the rotation of the floating body connecting belt to be extracted to the outside.

[0007]

According to the rotating device and the rotating force extracting device of the present invention, the upper opening of the cylindrical body is located in the atmosphere above the water surface, and the lower opening of the cylindrical body can enter the floating body in a substantially watertight state. The cylinder is kept at atmospheric pressure because the water is introduced into the cylinder through the drainage passage and the water that has entered the cylinder is discharged into the atmosphere through a drain passage. Since a part of the floating body connection belt is inserted through the cylinder held at the atmospheric pressure, attention is paid to the floating body which is going to enter the cylindrical body from the lower opening. Atmospheric pressure acts, and a water pressure according to the water depth acts on the lower surface. In this case, the force for pushing the floating body connection belt into the cylinder is larger than the sum of the buoyancy forces acting on other floating bodies. Therefore, a force for rotating the floating body connecting belt in a direction to push up the cylindrical body side portion is obtained, and as a result, the first and second guide wheels rotate, and the rotational force can be taken out.

Here, in the present invention, the smaller the buoyancy acting on the floating body and the larger the effective area on which the water pressure acts, the greater the rotational force. Therefore, the floating body of the present invention is preferably a floating body having a volume as small as possible to reduce buoyancy, and a shape having a large vertical projected area in order to increase the pushing force, such as a sphere and a short axial length. Cylindrical bodies can be employed. The floating body of the present invention desirably has low fluid resistance when moving in water and low frictional resistance when entering the cylinder. From this viewpoint, a sphere is most desirable, and the sphere is formed with a pitch as large as possible. A connected floating connecting belt is desirable.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIGS. 1 to 4 are views for explaining a rotational force extracting device according to a first embodiment of the present invention. In this embodiment, an example in which the present invention is used as a driving source of a generator will be described.

In the drawing, reference numeral 1 denotes a rotational force extracting device,
This is a water tank 2, a guide pipe (tubular body) 3 arranged in the water tank 2 for introducing atmospheric pressure into the water tank, and a drain pipe 7a for draining water that has entered the guide pipe 3.
A lower pulley (first guide wheel) 4 rotatably disposed at the bottom of the water tank 2, an upper pulley (second guide wheel) 5 rotatably disposed above the water tank 2, and Upper and lower pulleys 4,5
(Floating body) connecting belt 6 wound around.

The water tank 2 is a bottomed rectangular tube having an open upper end and a closed bottom, and an overflow pipe 2a for regulating the maximum water level is connected near the upper end opening. The guide pipe 3 has a structure in which a seal pipe 8 is connected to a lower part of a pipe main body 3a having an inner diameter slightly larger than a sphere (floating body) 10 of the sphere connecting belt 6 described later by a T joint 7. Lower opening 8a of the seal pipe 8
Is located on the bottom side of the water tank 2, and the water depth of the lower opening 8a is H. The upper opening 3b of the pipe body 3a is located above the highest water level. The seal pipe 8 is for suppressing the intrusion of water into the guide pipe 3 and has an inner diameter set to a size that allows the spherical body 10 to enter in a substantially watertight state. Smoothly processed to reduce. The length of the seal pipe 8 is set slightly longer than the connection interval L between the spheres 10. A branch portion of the T-joint 7 serves as the drain pipe 7a, and the drain pipe 7a penetrates the water tank 2 and protrudes outward.

The lower pulley 4 and the upper pulley 5 are formed on the outer peripheral surface of a disk with guide grooves 4a,
5a, and the upper pulley 5 has a larger diameter than the lower pulley 4. A rubber sheet 9 is attached to the guide groove 5a of the upper pulley 5 to prevent slippage.
A drive gear 5b for taking out a rotational force is formed in a portion of the outer peripheral portion of the upper pulley 5 adjacent to the guide groove 5a.

The sphere linking belt 6 is a ping-pong ball-shaped hollow spheres 10, 10 connected endlessly by a ring 12 with a gap of about 1/4 of the diameter D. Is set to L as described above.

A pinion gear 13 meshes with a drive gear 5b formed on the outer peripheral surface of the upper pulley 5. The rotating shaft 13a of the pinion gear 13 has a small generator 1
4 are connected. The generator 14 is configured to drive a generator main body 14b by the pinion gear 13 via a speed increasing gear mechanism 14a. The small motors 15 are connected to the generator 14.

Next, the operation and effect of this embodiment will be described.
In the present rotary force extraction device 1, when the water depth of the lower opening 8a of the guide pipe 3 is H, the number of the spheres 10 immersed in water within the range of the water depth H is n, and the diameter of the sphere 10 is D,
The upward force F acting on the sphere 10 ′ located at the lower opening 8 a is: F = γHS (γ: specific gravity of water, S: projected area of sphere = π
A D ^2/4). On the other hand, total F'buoyancy acting on the sphere 10 located within the range of the water depth H is F'= γVn: a (V sphere volume = πD ^3/6).

The above HS corresponds to the volume of a virtual water column formed vertically above the sphere 10, and Vn corresponds to the total volume of the sphere located at the H depth. Due to the structure of the sphere connecting belt 6, there is a gap between the spheres 10 (in the case of the present embodiment, there is a gap of about D / 4), so that HS> n
V, so that F> F '. A downward force corresponding to the weight (water depth L) of the water that has entered the guide pipe 3 acts on the sphere 10 ′.
, The relationship of F> F ′ does not collapse. As a result, in the case of the present embodiment, the sphere connecting belt 6 and, consequently, the lower and upper pulleys 4 and 5 rotate counterclockwise. Then, the pinion gear 13 is rotationally driven by the drive gear 5b of the upper pulley 5, whereby the generator 1
4 generates electric power, and the electric power causes the motor 15 to rotate.

On the other hand, in the case of the present embodiment, even if the seal between the seal pipe 8 of the guide pipe 3 and the sphere 10 is completely made, water corresponding to the volume A between adjacent spheres is supplied as described above. Invade 3 However, since this intruded water is drained through the drain pipe 7a, the spherical body 1
The downward weight acting on 0 'will not be excessive.
Note that the drained water needs to be replenished with natural water introduced from rivers, lakes, or the like, or tap water.

Here, in order to confirm the effects of the first embodiment, the rotational force generated by trial production of a test machine and the generator 1
4 was measured. First, the specifications of the tester were as follows. Water depth H: 1000 mm, sphere diameter D: 3
8 mm, connection distance L of spheres: 50 mm, total number of spheres: 57
Pieces, the number of spheres located within the range of water depth H: 20, the diameter of the upper pulley 5: 210 mm, the diameter of the drive gear formed on the pulley: 169.4 mm, the diameter of the pinion gear: 22.
4 mm. The generator was set to 3V at 8650 rpm.

The instantaneous stop load at which the rotation of the sphere connecting belt 6 was suddenly stopped by connecting a spring scale to the upper pulley 5 in the above state was 1.7 kg. Then, an effective rotational force is obtained in a state in which the inertia load has disappeared after a sufficient time has elapsed from the instantaneous stop.

Regarding the amount of power generation, two motors of the same type as the above-mentioned generator could be rotated. This result indicates that the electric output is sufficient. Conventional hydroelectric generators are limited to large-scale generators, such as requiring large-scale dam construction.Generally, small-scale generators use an internal combustion engine that uses oil as fuel. Met.
