Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention Naturally, the power of a river is directly converted into a rotational motion by directly capturing a deep water flow on a wide river surface.
The present invention relates to an apparatus configured to drive a generator. [0002] A conventional technology using hydraulic power is a hydroelectric power generator, a water turbine, or the like, which directly converts the flow of a river in a natural state into a rotary motion by directly capturing the water flow deeply over a wide river surface. There is no device configured to drive. [0003] Deterioration of the environment due to global warming has become an important problem relating to the future survival of mankind, and clean and low-cost energy is required. And solar power generation are costly and practically impossible. [0004] The present invention is an apparatus that uses the power of a river as an infinite, semi-permanent, and clean natural energy. The apparatus captures a water flow deeply over a wide river surface, converts the water flow into rotational motion, and drives the generator with the water flow. The feature of this device is that it has an overwhelming difference in output due to the difference between the weight of air and water in comparison with wind power generation. The goal is to get-. [0005] A device configured to directly capture the power of a river flowing in a natural state and capture the water flow deeply over a wide river surface to drive a generator. Attach the bearings to both ends of the two shafts, fix the belt pulleys on the left and right sides inside, and fix the bearing part together with the shaft one by one at the front and back inside the frame, The front and rear belt pulleys are wrapped around two left and right endless belts, and a plurality of plates are rotatably fixed between the two left and right endless belts without interruption. This device is designed so that it moves continuously on a plane according to the height of the river, catches the water flow deeply over a wide river surface, converts the rotation into rotational motion by receiving the force from the belt pulley, and drives the generator with the water flow. Embodiments of the present invention will be described with reference to the drawings based on examples. FIG. 1 is a cross-sectional view taken along the line AA ′ of FIG. 3, and the right side of the line AA ′ is omitted. Buoyancy body 9
A rectangular frame 8 is fixed on the upper side, and four belt pulleys 6 and 10 are attached to the two shafts 5 one by one on the left and right sides inside the frame. The front and rear belt pulleys 6 and 10 are wrapped around two endless belts 7 on the left and right sides, and a plurality of plates 2 receiving the water flow without interruption between the two endless belts 7 on the left and right sides are rotatably fixed. The diameter of the belt pulleys 6 and 10 is large enough that the plate 2 receiving the water flow rotates with the blades 1 attached thereto. In order to prevent slip loss, the diameter increases as the force applied to the endless belt 7 increases. The contact area between the endless belt 7 and the belt pulleys 6, 10 is increased. The plate 2 is provided with the blades 1 and the ribs 3, the air vent holes 4 are opened, the water flow is captured at the depth of several blades 1, and the plurality of plates 2 continuously move in a plane,
Capture the water flow deeply over a wide river surface
Is a device configured to receive a force and convert it into a rotational motion to drive the generator 12 with the water flow. When the plate 2 is pushed by the water flow and the endless belt 7 starts to rotate and the plate 2 receiving the water flow is away from the river surface, the center of gravity of the plate 2 is taken, the side with the blades 1 is directed downward, and the water is drained off. The power obtained by receiving the water flow is concentrated on the power for turning the generator 12. FIG. 2 is a perspective view of a plate 2 for receiving a water flow. Several blades 1, ribs 3, and air vent holes 4 attached to the plate 2 allow the water flow due to the effect of the depth of the plate 2 and the several blades 1. The width and length, the number of blades 1 and the depth vary depending on the river conditions (river width, water volume, water speed, water depth, river bottom shape, river surface gradient, etc.), and the material should be lighter and stronger. Good, but heavier than water is more stable. The shape of the blade 1 is such that the plate 2 is in contact with the river surface so as to efficiently receive the water flow. Turn and install one or several blades 1 in it. The rearmost part of the blades 1 attached to one plate 2 is made as large as possible and the front side is made small gradually to disperse the force of the received water flow. The plate 2 and the blades 1 are sandwiched at right angles to the blades 1 and the ribs 3 are attached perpendicularly to the plate 2 so as to increase the strength so that the plates 2 and the blades 1 are not damaged by water pressure generated when receiving the water flow. When the blade 2 and the rib 3 which receive the water flow are attached to the plate 2 and the plate starts moving and the river surface is touched, air enters in a state where the space between the plate 2 and the river surface is sealed, and the plate 2 rises up and becomes unstable and does not receive the water flow sufficiently. Therefore, a hole 4 for venting air is formed in the plate 2 to remove air and receive a sufficient flow of water to obtain a strong force. Further, when leaving the river surface, no load is applied and the power is efficiently removed to improve power generation efficiency. FIG. 3 is a plan view of an apparatus configured to drive the generator 12 by a water flow. The basic form is a rectangular frame 8 and the state of a river to be installed (river width, water volume, water speed, water depth). , Riverbed shape, river surface gradient, linear flow, meandering flow, etc.)
Width and length change according to. A buoyant body 9 is fixed below the left and right ends of the frame 8. The buoyant body 9 is a ship or a sealed pipe-like object, and is used to adjust buoyancy and to put a gutter between the buoyant body 9 and the frame 8. The plurality of boards 2 receiving the water current when turning around is adjusted to the height of the river surface. Bearings 11 are attached to both ends of the two shafts 5 in the frame 8, and four belt pulleys 6 and 10 are attached to the left and right inside of the shafts, respectively. This bearing 1 together with the shaft 5
One part is fixed to the frame 8. Front and rear belt pulleys 6, 1
0 is wrapped around two endless belts 7 on the left and right sides, and a plurality of plates 2 receiving the water flow without interruption are fixed between the two endless belts 7 on the left and right sides in a freely rotatable manner. With these structures, several blades 1 receiving a water flow continuously move in a plane with a plurality of plates 2 to catch the water flow deeply on a wide river surface, and the belt pulleys 6 and 10 receive a force to convert to a rotational motion to generate electric power. A device configured to drive the machine 12. As the endless belt 7, a V belt, a chain, or the like can be used. The width of the plate 2 receiving the water flow is a size that falls between the left and right belt pulleys 6 and 10, and the length is the shaft 5 and the belt pulleys 6 and 10 with the blades 1 attached.

Water volume, water speed, water depth, river bottom shape, river surface gradient, etc.), the length of the plate 2 is short if the force applied to the plate 2 and the blade 1 is large, and the length of the plate 2 is long if the force applied is small. I do. The installation place of the generator is fixed on the body frame,
It is driven from the shaft on which the belt pulley is mounted using a power transmission device such as a gear or an endless belt. The speed of the river flow is not fast, but due to the effect of the area of the plurality of boards that are in wide contact with the river surface and the depth of the blades, a large amount of water flow is captured,
Since the power is strong, use a transmission to increase the rotation speed and drive the generator.
