Abstract

PURPOSE:To obtain an efficient generation of electricity by mounting a water wheel between two hulls and rotating its several blades in accordance with the vertical movement of water surface and the directional change of tidal current. CONSTITUTION:Respective bows 7A and 7B of two hulls 3A and 3B are streamlined and constantly directed to the upper stream of a tidal current, while a projected part 7 of bows of hulls 3A and 3B is pivotted by a pin on a mooring rod 6 to be easily slided round a fixed prop 5 for following the vertical movement of the surface of water. Between two hulls 3A and 3B, a water wheel 2 is mounted via a shaft 2A, while at proper positions of the shaft 2A, a gear 9 and a pinion 11 are fixed for driving a power-generator 12. Thereby, several blades of the water wheel 2 are pushed by a tidal current for totating the shaft 2A in accordance with the constant change of the tidal current and the wave. This construction permits to obtain an efficient generation of electricity by the generator 12.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to generate electricity by using tidal currents in straits and other underwater areas.
The several blades that make up the water wheel make one revolution and enter the water one by one from above the water surface. The waterwheel is pushed and rotated, and the waterwheel is installed in the middle of a pair of hulls that are separated into two parts floating on the sea surface. The hull, which is supported by a water wheel, is moored to a floating anchor or a fixed pillar, and automatically responds to changes in the direction of the tidal current and vertical movements of the water surface, and gradually moves to the water surface. The blades of a water wheel that receive pressure from the tidal current rotate alternately underwater near the water's surface and above the water's surface, providing efficient power generation.

Next, the structure of the invention will be described.As shown in FIG. Insert the protrusion 7 at the leading edge of the joint of the two halves of the hull into the freely floating mooring rod 6 centered on the anchor 5 or the fixed pillar 5, facing the direction of the pin. 7A supporting tidal current flows smoothly in response to changes in direction and vertical movements of the water surface, and water turbine 2
When the Hane well rotates downward, the water surface level is 1.
It is supported and installed in a position that is within the tidal axis, and the tidal current -
A gear 9 for transmitting power is installed on the rotating shaft 2A of the water wheel 2 at an appropriate position on the hull 3A (or 3B), and the power of the water wheel 2 is transmitted through its rotation shaft 2A. Binion 11 that meshes with the power transmission gear 9 and transmits power to the power generation shaft
The hull 3A3 is divided into two parts and transmits power by installing
The continuous binding of B is its bone axis a! The water turbine 2 and the power transmission and power generation devices 9 to 12 are covered with wave IB cover 4A, and the water turbine 2 and the power transmission and power generation devices 9 to 12 are installed on the deck of the ship. 4 to form a device that prevents the invasion of waves IB.

Next, we will discuss the operation of the water wheel 2, which is installed in a strait with a fast current. The power generated on the two rotating shafts of the water wheel 2 in the tide shaft near the water surface and on the water is transmitted to the power generation power shaft IO via the power transmission gear 9 and the pinion, Power is provided without limit.

The present invention uses two separate hulls 3A and 3B equipped with a device to deal with constantly changing tides and waves IB.
The supported water wheel 2 rotates on the surface of the water and the tidal current, increasing the rotational force of the water wheel 2, effectively utilizing the pressure of the tidal material, and collecting natural energy indefinitely. It is a device that generates electricity.
