Description

Water type hydroelectric power plant with improved power generation efficiency

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydroelectric power plant, and more particularly, to a water-type hydroelectric power plant in which water wheels rotate to produce electricity through flowing water in a floating state.

In general, hydroelectric power refers to converting potential energy of water located at a high place into kinetic energy by aberration, and obtaining electric energy through a generator connected to the aberration.

In general, for such hydroelectric power generation, a dam is formed by blocking a river, and water is confined upstream of the dam, and water is flowed down through the pipeline to turn aberrations installed on the pipeline.

As such, the conventional hydroelectric power generation has a disadvantage in that enormous costs and resources must be invested because dams and waterways must be constructed.

In addition, the conventional hydroelectric power generation is limited to places where dams and waterways can be constructed, and there are many restrictions on the installation place. In addition, in order to transmit the generated electricity to an independent house such as a mountain or a river, power transmission facilities are separately provided. In addition, it is not only a burden in terms of the cost to build a power transmission facility, but also has a problem that power loss due to power transmission.

In order to solve the above problems, the present applicant has proposed a hydroelectric power generation facility that can obtain a rotational force of aberration using flowing water such as a river, a stream, a valley, etc. without installing a dam or a waterway (Registration 10-1596586). )

However, the hydro power generation module of Patent No. 10-1596586 proposed by the present applicant had a structurally regret about power generation efficiency. Accordingly, the hydro power generation module disclosed in Korean Patent No. 10-1596586 was not satisfied with the power generation efficiency aspect. Continued research and development of hydropower modules with very improved structure.

(Patent Document 1) Registered Patent 10-1596586

The present invention has an object to provide a water-type hydroelectric power generation equipment having an improved structure to improve the power generation efficiency while solving the conventional problems as described above.

The water flow guide plate is formed in pairs, protruding downward from the lower surface of the hull portion, and may be formed in such a way that the gap between the water flows toward the front so that the water flows toward the waterway.

And a cover member formed to cover both ends of the channel in the width direction and configured to surround a lower end of the aberration.

The aberration includes an aberration body rotatably installed on the hull portion and a plurality of wings radially installed on an outer circumference of the aberration body, and each of the plurality of wings is provided with a packing member, An end portion of the packing member may be configured to contact the bottom surface and both inner surfaces of the cover member so as to enhance the rotational force of the aberration.

According to the above, since the waterways are formed in a line in the front-rear direction on the lower surface of the hull, and a plurality of aberrations are rotated along this waterway, the amount of power generation is improved because the power generation is caused by the rotation of each aberration. In particular, since a plurality of waterways are formed in parallel in the horizontal direction in the hull portion, and a plurality of aberrations are provided for each waterway, power generation is further improved by a plurality of aberration rotations, which greatly improves the efficiency of hydroelectric power facilities. It is effective.

On the other hand, in the present invention, by installing a plurality of aberrations 20 along each of the waterways 13, the first aberration 20 installed on the current side of the waterway 13 can rotate without decreasing the flow rate of the water flow, but the waterway 13 The second aberration 20 installed on the downstream side of the rotor is rotated through the water flow reduced by the first aberration 20, so that the rotational force may be lowered compared to the first aberration 20, and the third aberration (the same as the downstream side) 20) the rotational force may be lowered by the flow rate further reduced flow.

Thus, the present invention is a water flow guide plate 55 and aberration rotation for inducing water flow in the second and third aberration 20 as well as the first aberration 20 on the water channel 13 on the lower surface (10a) of the hull portion (10) It is configured to further include a reinforcing cover member (60).

Water flow guide plate 55 is composed of a pair, protruding downward from the lower surface (10a) of the hull portion 10, but in an inclined form in which the interval between the water flow toward the waterway 13 is gradually narrowed. Is done. That is, the water flow guide plate 55 composed of a pair is installed in a form that opens toward the front on both sides of the waterway 13.

The water flow guide plate 55 is installed at predetermined intervals along the water channel 13, and is installed to be located in front of each of the water wheels 20 located in the water channel 13.

Specifically, the first water flow guide plate 55a constituted by a pair on the front side of the first aberration 20 on the water channel 13 is installed, and the second water flow guide constituted by a pair on the front side of the second aberration 20.

There is no gap between the tip of the blade 24 and the cover member 60, and thus, the force of the water flow pushing the blade 24 is increased, so that the rotational force of the aberration 20 can be significantly improved.

In the present invention, the aberration rotation reinforcement cover member 60 is configured to be connected to both ends of the front end and the rear end of each of the water flow guide plate (55a, 55b, 55c), accordingly, to the water flow guide plate (55a, 55b, 55c) Not only is the water flow guided to the water channel 13a, but also directs the water flow into each cover member 50, so that the rotational force of each aberration 20 can be further increased.

As described above, the present invention provides the water flows flowing from the lower portion of the hull portion 10 by the respective water

flow guide plates

55a, 55b, and 55c to each aberration 20 sequentially positioned from the current side of the channel 13 to the downstream side.
