JPH0719154A - Electric power generation utilizing sea level change by low-high tide and principle of buoyancy - Google Patents

Abstract

PURPOSE:To obtain electric power generation by the buoyancy of water and the ebb-flow change of the tide by making a container, floating on the water surface, rise in association with the rise of water level, interlocking numerous pulley groups or the like different in size making use of the buoyancy, and making the rotating speed of a shaft high so as to rotate a generator. CONSTITUTION:A lightweight container A is made float on the water surface, and the other end of a wire rope with one end thereof connected to the container A is wound around a pulley C1 through a pulley B installed on the water floor face. The container A rises in association with the rise of the water level, and the pulley C1 is rotated being pulled through the wire rope wound around the pulley B. Pulley groups C1-C2-E1-E2, n, each pair of which is mutually different in size and fixed to each other on a shaft, are interlockingly rotated in succession through belts. The rotating speed of the respective pulley groups C1-C2-E1-E2, n is thereby made faster toward the rear, so that the shaft G is rotated to actuate a generator F. Electric power is thus obtained making effective use of the buoyancy of water and the ebb-flow of the tide.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention generates electricity by utilizing the following three basic characteristics: 1) Utilizes changes in sea level due to ebb and flow of tides. For example, the amount of seawater increases from low tide to high tide. The gravity of this increasing seawater is used to generate electricity.

2) Therefore, the principle of buoyancy is used. That is, when an object is placed in water, an amount of water corresponding to the volume of the object is removed. If the lightweight container floats above the sea surface, the container will be pushed up with the sea surface as the tide goes from low tide to high tide. Use this power. However, the amount of change in sea level due to changes in tide is relatively small per fixed time, and therefore the amount of momentum that can be obtained by utilizing the increased gravity of seawater is limited as it is. Therefore, the momentum is amplified by the following method.

3) When two pulleys with different diameters are connected by a belt and rotated, a faster rotation speed is obtained with a smaller pulley than the rotation speed of a large pulley.

Using the above three conditions, the invention relating to the following power generation was carried out: As shown in FIG. 1, a wire rope is fixed to a light, hollow hollow container A floating in water. . This wire rope goes through a pulley B fixed to a concrete block placed on the sea floor and a small pulley C
It is connected in a wound state. Further, the small pulley C1 and the large pulley C2 are integrally fixed to each other. Regarding the next largest pulley C2 and the smallest pulley D1, the rotation of C2 is transmitted to D1 via a belt. Since the diameter of C2 is larger than that of D1, when the rotational movement of C1 is transmitted to C1 through the belt from C2 integrated with C1, a rotational speed higher than that of C1 is obtained at D1. With the same principle, the rotation speed of C1 is E1 through D1 and D2.
Will be further accelerated. According to the same principle, a method of increasing the rotation speed by engaging gears having different diameters instead of the pulley can be used. A lightweight container A with a hollow inside floats on the surface of the water, but as the tide goes from low tide to high tide, the container A rises with the surface of the water. At this time, the container A is fixed to the wire rope, and the wire rope is further wound around the small pulley C1 through the pulley B. Therefore, the small pulley C1 gradually rotates as the container A rises with the sea surface. Do it. The rotation speed of the small pulley C1 is relatively slow, but this is C2, D1, D2, E1, E.
2. ． ． It accelerates gradually with n, and a considerably high rotational speed is obtained at the last pulley n. The last pulley n is fixedly connected to the shaft G of the generator F. With such a mechanism, as the container A rises upward as the sea level rises from low tide to high tide, each pulley rotates, and from the shaft G of the last pulley n to the shaft G of the generator F from C1. The rotational movement of is accelerated and transmitted, and the generator F rotates in this way to generate electric power. When the high tide changes to the low tide, rotate the wire rope C1 in the opposite direction and return it to its original position to keep the tension in the initial state again. Generate electricity.
