Abstract

PURPOSE:To generate electric power by efficiently utilizing the energy of water flow by installing a guide plate for branching the water stream to the upper and lower parts onto the side part of a float structure body and installing a water-wheel which revolves in one direction in the float structure body and connecting said water-wheel to a generator. CONSTITUTION:In order to utilize the water power, e.g., the ocean waves, piles 13 are driven onto the sea bottom, and the body 1 is installed onto the piles 13, and moved vertically by the vertical movement of the sea surface. A bearing 4 for supporting a water-wheel 6 is installed into the body 1, and the shaft 5 of the water-wheel 6 is connected to a generator 9 through a gear box 7 and a chain 8. Further, a float 3 is installed under the side plates 2 surrounding the water-wheel 6, and a guide plate 11 is installed between the side parts of the side plates 2. Therefore, waves are introduced into the water-wheel 6 from upper part of the guide plate 11, and led out to the lower part of the guide plate 11 from the water wheel 6. Therefore, the water-wheel 6 is always revolved in one direction by the wave power, and the generator 9 can be revolved by the turning moment.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> This energy generation device supplies inexpensive energy to industry and all other fields, and is used as a distributed energy source.

<Conventional technology> Conventional energy supply sources are represented by one-stone ponds, thermal energy conversion using nuclear power, and hydroelectric power generation, but each energy source has a limited supply.
It is clear that the balance between demand and supply will be disrupted in the near future, and basic countermeasures have been put in place to deal with this for some time, but the reality is that there is currently no such technology. The present invention relates to a technology and a device that solves these problems, and efficiently converts commercial wave energy, which has not been used much in the past, into electrical energy.

<Problem that the invention seeks to solve> Since we cannot hope for limited energy sources such as petroleum, we thought of making maximum use of ocean waves and river running water around our country as an alternative. is the present invention. This inexhaustible and never-ending energy source is utilized, and even a small and resource-free country like ours can utilize its advantage as an island nation to install the device of the present invention all along its shoreline. Although it is possible to generate electricity using this method, there are currently not many methods of generating electricity using this method.Although methods of using waves and running water have been considered, it has not been possible to easily create a device for this, and to this day, this is the method of the present invention. This is what makes it possible.

<Prior Art> Conventionally, there are small-scale devices that convert sea waves or river flows into electrical energy, and in other words, the use of sea waves is used as an auxiliary power source for lighthouses and the like. This is a small device with a very small power generating capacity, floating a buoy of about 1 meter, and incorporating a water wheel and a generator.There is no large power generation device, and there is no method of directly using the flow of the river. There is no technical solution to creating a device that would generate a small amount of electromotive force by attaching a generator to a small water wheel, which would at least be enough for Iruma to use in his daily life. Usable water resources were simply being used as waste, which was a huge loss, and a technical solution was needed.

Problems to be Solved by the Invention As mentioned above, conventional methods and devices are inefficient in utilizing ocean wave energy, river flow energy, etc. Because there are not many ideas to deal with this problem, it is not possible to efficiently transmit energy to the water turbine and generate electricity.

Furthermore, since the flow rate of a river constantly changes from day to day, stable rotation cannot always be obtained with a fixed water wheel.This invention technically solves the above-mentioned problems.

Means for Solving the Problems> As a means to solve the above problems, we will first discuss the method of using ocean waves. Drive it in and attach the main body l to this. This main body follows the vertical movement of the sea level as indicated by the arrow.
It moves up and down. A bearing 4 that holds a water wheel 6 is installed in the Kimoto lO, and a pin P-box 7 is installed on the shaft 5 to increase the rotation and launch the water wheel 6.
Connect to machine 9. Alternatively, it may be connected by TEN 8, etc., the water Jl [6 is when the tide is rising] [1-T 3 floats, and when the tide is ebbing, it falls and always maintains a constant position with the sea surface. A plate U that changes the direction of the flow when coming and returning is supported by the fulcrum shaft 1o,
When waves come, the waves mainly pass over the waterwheel, giving rotational force to the waterwheel 6 at this time. Also, when turning back, the water flows under aquatic plants, so the direction of rotation of the water wheel is always the same. ! ! In the method of using the flow of a river, you can connect this device with a wire such as a wire and float it.

While moving up and down, the water wheel rotates and generates electricity.

(Operation) Since the water wheel utilizes waves or river flow, the shape of the water wheel is longer than shown in Figure 2, and the diameter does not need to be too large. It is advantageous for use, and it is easy to manufacture large power generation water turbines by simply making the basic shape longer.Therefore, the Nerdy action of waves at low water level can be sufficiently converted into rotational force. can be used round trip.

<Embodiment> Although the above-mentioned device is installed on a coastline or a river, it is safe to install one pillar 13 to support the device.

Also, you can move the main body up and down along the rails that were previously installed.
Alternatively, in the case of a river, it may be supported by an a-pu, and can be installed in a fenced area in any location.

<! ! Effects of light> As mentioned above, the water turbine method power generation device based on the water level regulation structure has low installation costs, is very advantageous compared to hydroelectric power generation using large dams, and has no restrictions on location. In addition, the cost of power transmission equipment is low, making it ideal as o-cal energy. In a resource-poor country like ours, we have been able to utilize waves and running water, which are the only major energy resources, on the beach. This is a power generation device that uses the power of waves.
