Description

本発明は、海流を利用して発電を行うために海底に設置する海流発電装置に関するものである。   The present invention relates to an ocean current power generation apparatus installed on the seabed in order to generate electricity using ocean currents.

発電装置としては、従来、火力発電装置や原子力発電装置などが広く利用されてきたが、二酸化炭素の排出や放射線漏れなどの社会問題を受けて、近年では、安全で環境に優しい自然エネルギーを有効活用した発電装置が注目されている。   Conventionally, thermal power generation equipment and nuclear power generation equipment have been widely used as power generation equipment, but in recent years, in response to social problems such as carbon dioxide emissions and radiation leakage, safe and environmentally friendly natural energy has become effective. The power generators that have been used are attracting attention.

自然エネルギーを有効利用した発電装置の一つとして、日本の周囲に存在する海のエネルギーを利用するために、海底に設置して海流を利用して発電を行う海流発電装置が考案されている（たとえば、特許文献１参照。）。   As one of the power generators that make effective use of natural energy, ocean current power generators have been devised that use the ocean current to generate power in order to use the ocean energy that exists around Japan. For example, see Patent Document 1.)

従来の海流発電装置は、海流によって回転翼を回転させて発電を行う発電ユニットを海底から上下に並べて設置する構成となっている。   A conventional ocean current power generation apparatus has a configuration in which power generation units that generate power by rotating rotor blades by an ocean current are arranged side by side from the sea floor.

特開２００７−９８３３号公報JP 2007-9833 A

ところが、上記従来の海流発電装置では、単に発電ユニットを上下に並べて設置した構成となっているために、充分な発電量が得られないおそれがあった。   However, since the conventional ocean current power generation apparatus has a configuration in which power generation units are simply arranged one above the other, there is a risk that a sufficient amount of power generation cannot be obtained.

これは、海流を利用して発電を行うために海流発電装置を海底に設置した場合、海底側と海面側とで海流の流速分布が異なっているために、単に発電ユニットを上下に並べて設置しただけでは、比較的速度の大きい海面側において海流のエネルギーを電気エネルギーに充分に変換しきれずにいたためである。   This is because when the ocean current power generation device is installed on the ocean floor to generate power using ocean currents, the ocean current flow velocity distribution is different between the ocean floor side and the ocean surface side. This is because the ocean current energy could not be fully converted into electrical energy on the relatively high speed sea surface side.

そこで、請求項１に係る本発明では、海流を利用して発電を行うために海底に設置した海流発電装置において、複数の発電ユニットを上下方向に向けて配置するとともに、各発電ユニットに他の発電ユニットを海流方向に向けて連結可能とすることにした。   Therefore, in the present invention according to claim 1, in the ocean current power generation device installed on the sea floor in order to generate power using the ocean current, a plurality of power generation units are arranged in the vertical direction, and each power generation unit has another The power generation unit can be connected in the direction of the ocean current.

また、請求項２に係る本発明では、前記請求項１に係る本発明において、下方の発電ユニットよりも上方の発電ユニットに多くの他の発電ユニットを連結することにした。   Further, in the present invention according to claim 2, in the present invention according to claim 1, many other power generation units are connected to the power generation unit above the power generation unit below.

そして、本発明では、以下に記載する効果を奏する。   And in this invention, there exists an effect described below.

すなわち、本発明では、海流を利用して発電を行うために海底に設置した海流発電装置において、複数の発電ユニットを上下方向に向けて配置するとともに、各発電ユニットに他の発電ユニットを海流方向に向けて連結可能としたために、海流の速度分布が海底側と海面側とで異なる場合であっても海流のエネルギーを有効に電気エネルギーに変換することができ、発電量を増大させることができる。   That is, in the present invention, in the ocean current power generation device installed on the sea floor to generate power using the ocean current, a plurality of power generation units are arranged in the vertical direction, and other power generation units are arranged in each ocean current direction. As a result, it is possible to effectively convert the ocean current energy into electrical energy and increase the amount of power generation even when the ocean current velocity distribution is different between the ocean floor and the ocean surface. .

特に、下方の発電ユニットよりも上方の発電ユニットに多くの他の発電ユニットを連結することにした場合には、比較的速度の大きい海面側において海流のエネルギーを電気エネルギーに充分に変換することができ、発電量を増大させることができる。   In particular, when many other power generation units are connected to an upper power generation unit rather than a lower power generation unit, it is possible to sufficiently convert ocean current energy into electrical energy on the sea surface side at a relatively high speed. And the amount of power generation can be increased.

The number of power generation units 10 to be connected can be changed according to the current velocity distribution according to the height from the seabed.
