Description

The present invention converts the energy of flowing water in a waterway or river into rotational energy with a conveyor turbine and connects it to power generation.

Speaking of hydropower, the first thing that comes to mind is a large dam and a power plant that uses the potential energy of the water generated by that dam.
Hydroelectric power generation, which does not emit carbon dioxide, is popular all over the world as clean energy, but when a dam is used, it requires a certain geographical location environment, a sufficient amount of water, and large-scale civil engineering work.
Therefore, a power generation system using a low head canal has recently attracted attention.
It is said that running water nurtures a large amount of energy and the capacity factor is considerably higher than that of solar and wind power.
The present invention aims to lead to small hydroelectric power generation by fully utilizing the energy of flowing water such as irrigation canals and rivers.

Power generation using irrigation canals or rivers has been around for a long time, but its scale is small, profitability is severe, and maintenance is troublesome, so its spread as a business is not good enough.
Most of the conventional low-head power generation is like a conventional water turbine, and it is fixed across the irrigation canal for installation, or it is fixed with a certain slope (spiral type) by river construction. Is common. Therefore, it is difficult to install it in a wide river and the utilization rate is low.

In the present invention, since the fixed stand is installed directly in the water stream, it is not easily affected by the width of the waterway and does not require river construction. Since the flow of water is received by a plurality of receiving plates as it is and the conveyor is moved by a linear motion longer than that of a normal water turbine, the rotational torque is large and the low head running water energy can be efficiently converted into mechanical energy.
In addition, since the rotation torque is large, it is not easily affected by impurities, and stable rotation can always be obtained regardless of the time of day, which can be connected to business power supply.

It is a device that can be installed anywhere where water flows due to low heads such as irrigation canals and rivers, and it is less affected by seasons, day and night, wind, etc., and can always supply power efficiently at low cost.

It is a front view of the power generation device of the conveyor water turbine of this invention. It is a perspective view of a conveyor water turbine. It is an image diagram of a state in which a plurality of conveyor turbines are connected.

Hereinafter, the power generation system of the present invention will be described based on the embodiment shown in the figure.

FIG. 1 is an image diagram of a single power unit for power generation of the present invention.
First, a fixed mount (1) is installed in a river or irrigation canal. Rotating rollers (2) and (3) are attached to both ends of the lower part of the fixed frame. The rotating roller (4) is fixed to the upper end of the vertical fixing support in the middle, and the roller (4) is always at a height above the water surface.

A plurality of receiving plates (6) are fixed to the surface of the belt conveyor (5) and installed so as to surround the rotating rollers (2), (3) and (4) so that they can rotate. When the conveyor rotates, the backing plate (6) attached to the surface is sequentially deployed by the water flow as it passes through the roller (2) (so that the opening angle with respect to the conveyor does not exceed 90 degrees).

The force of the water receiving plate rotates the entire conveyor, and the three rollers also rotate at the same time.
A coaxial gear (7) is installed on the upper rotating roller (4) and connected to a generator to generate electricity.

When the water flow flows from the rotating rollers (2) to (3) as shown in FIG. 1, the receiving plates attached to the belt conveyors are in the deployed state, and the machine that propels the water flowing force in the same direction. Convert to force and move the conveyor from (2) to (3). At that time, the rotational force that the conveyor rotates the rollers is close to the total propulsive force of the receiving plates developed between (2) and (3), respectively.

If the rotational energy obtained above is connected to a power generation turbine to generate power, the power generation efficiency will be considerably higher than that of a conventional water turbine.

The size and scale of the equipment of the present invention can be changed depending on the situation, and the size can be changed flexibly depending on the depth of the water flow and the width of the river. In some cases, it is possible to generate electricity with a larger force in a state where a plurality of units are connected by a roller chain or the like (see FIG. 3).

The equipment of the present invention is simple and easy to install, and because it has a large rotational force, it is not easily affected by the season, day and night, and head, and it enables stable energy supply at all times.
