Description

The present invention mainly relates to a flowing-water floating hydroelectric power generation device for the purpose of performing relatively small-scale power generation including general household use by an extremely simple means. Even if there is a difference in the size of the device, the number of devices, the amount of power generation, etc., it is intended to provide a flowing-water floating type hydroelectric power generation device that can generate electricity. Populations or natural streams, irrigation channels, diversion water in rice fields, digging splits, gutters, and other small water flows are also possible, and it is more effective if the amount of water and flow velocity are large.

Related to the recent accidents at nuclear power plants and the global rise in fossil fuel prices, the effective use of renewable energy is becoming an urgent issue.
On the other hand, as hydropower generation, large-scale hydropower generation such as dam type is well known, but relatively small and simple hydropower generation with a view to home use was also very interested. It seems that it has finally begun to be proposed only recently.

The present invention relates to hydroelectric power generation that is one of the effective utilization power generation of natural energy, but is not a large-scale device like the conventional hydroelectric power generation, and is similar to a solar power generation panel, etc. In relation to floating hydropower generators that are intended to perform relatively small-scale power generation, such as, in the case of flowing water, that is, if there is a flow of water, the size of the device, the number of devices Even if there is a difference in the amount of power generation, etc., a flowing water floating hydroelectric generator capable of generating power is provided.

Conventionally, large-scale hydroelectric power generation such as dam type is well known, but relatively small-scale, simple hydroelectric power generation with a view to home use has not attracted much interest recently. Thus, there has been a problem that has not yet been provided in a state where it has finally been proposed, and which can be applied to a wide range of practical uses, including configuration and cost.

According to the first aspect of the present invention, a generator that generates electric power by rotation of a driving shaft and a power transmission mechanism that transmits the rotational power of the water turbine described later to the driving shaft are incorporated in a float housing having buoyancy that keeps the surface floating at all times. In addition, a rotating shaft of a water turbine that rotates by flowing water energy is pivoted on a bearing fixed to the lower surface of the float housing, so that the water wheel is always located in water, the rotating shaft of the water wheel and the power transmission Concatenating mechanism,
The float housing is moored at a fixed point installed in the running water or on the coast of the running water, suspended in the running water, the turbine is rotated by running water energy, and the rotational power is transmitted to the driving shaft of the generator via the power transmission mechanism. The problem is solved by a flowing-water floating hydroelectric generator characterized in that it is configured to generate power by rotating to transmit.

According to a second aspect of the present invention, in the flowing water floating hydroelectric generator, the power transmission mechanism is a gear mechanism, a pulley / belt mechanism, a flexible shaft mechanism, or a combination thereof. The problem is solved by the floating water hydropower generator.

According to a third aspect of the present invention, in the above floating water floating hydroelectric generator, the float housing is provided so as to be moored at a fixed point installed on the shore of running water or running water, and the mooring means is a hook. The problem is solved by the flowing water floating hydroelectric generator according to claim 1, wherein the problem is a rope, a wire rope, a chain, or a combination thereof.

This type of conventional hydroelectric power generator is not limited to wherever there is running water, only the configuration of the hydroelectric power generator, such as the size of the river, selection and adjustment of the river width, selection of the head of the water current, artificial formation, etc. However, the installation, installation location, mechanical design, etc. were not easy, but in that respect, the flowing water floating type hydroelectric power generator of the present invention is small or large if the flowing water, that is, the flow of water exists. Even if there is a difference in the number of units, power generation amount, etc., large and small rivers will of course be installed in flowing populations or natural streams, irrigation channels, diversion water in rice fields, digging splits, gutters, and other small running water to generate electricity It is possible to generate electric power more effectively if the amount of flowing water and the flow velocity are large.

Since the float housing is always floated and floated, the float housing can be freely synchronized with the size of flowing water such as water rivers, strength of flow, increase / decrease of water volume, fluctuation of flow etc. There is an effect of being able to follow and continuously generate power.

Since the water wheel that rotates with flowing water energy is provided on the lower surface of the float housing so as to be always in the water, the water wheel has a characteristic that it can inevitably rotate and generate electricity as long as there is a flow of water.

There is a feature that it can be installed very simply by mooring the float housing at a fixed point with appropriate mooring means such as hooks, ropes, wire ropes, chains, or a combination thereof.

The method of installing the flowing water floating hydroelectric generator of the present invention can be selected depending on the case. For example, there is an advantage that a plurality of units can be installed in columns or rows in addition to being installed alone.
