The air compressed in the submersible 3 is stored in each compressed air tank 4 provided at the top of the submersible due to the rise of the sea level in the submersible 3 at full tide. The stored compressed air is generated via the compressed air feed pipe 7 by rotating the compressed air utilization turbine 11 and rotating the connected generator. At the time of ebb tide, the sea level in the submersible 3 is lowered, and the inside of the submersible becomes negative pressure, and the air flowing in from the outside rotates the negative pressure air utilization turbine 12 and rotates the connected generator to generate power. The inflow air that has rotated the turbine flows into the submersible via the negative pressure air concentration pipe 13 and the negative pressure air inflow pipe 15.

Description

必要数の潜函を海岸岸壁に接して、潜函下部が最大干潮時の海面の位置に、上面は最大満潮時の海面の位置に設置し、圧縮空気の正負の圧力や波浪・風圧などによる潜函や付属施設の倒壊を防ぐため、必要な箇所に梁・脚柱をつけ、脚柱は地中に挿入してコンクリト打設、厳重に潜函を固定し、各潜函上にそれぞれ圧縮空気タンクを設置する。 Install the required number of dives in contact with the coastal quay, install the bottom of the diving at the sea level at the maximum low tide and the top at the sea level at the maximum high tide. In order to prevent the attached facilities from collapsing, beams and pedestals are attached to the necessary places, the pedestals are inserted into the ground, concrete is placed, the submersibles are strictly fixed, and a compressed air tank is installed on each subentry. .

満ち潮によって潜函内に生じる圧縮空気をタンクに圧入貯蔵しておき、順次タービンに送って発電し、引き潮時には海水の流出によって生じる全潜函の負圧を負圧利用タービンに集中して発電する潮汐発電装置に関する。 Tidal power generation in which compressed air generated in the submersible due to high tide is press-fitted and stored in a tank, and then sent to a turbine to generate power, and the negative pressure generated by seawater outflow is concentrated on the negative pressure turbine when submerged.

従来の潮汐量の変化を空気圧に変換する発電の方法は潮汐の全量を空気圧に変換しておらず、潮汐停滞時には発電を中断するものもあり、施設装備も複雑で巨大になり、莫大な費用がかかり、実用化には問題がある。 The conventional method of power generation that converts the change in tide amount to air pressure does not convert the entire amount of tide to air pressure, and there are some that interrupt power generation when the tide is stagnant, and the facility equipment becomes complicated and huge, and the huge cost And it has a problem in practical use.

公開されている文献の発電技術は、潮汐量の変化を十分に空気圧に変換できないし、潮汐停滞時は発電が中断され、構造や運転の仕組みが複雑で、洞窟や巨大なタンク設備に莫大な費用がかかり、施設の移転移動も困難で、事業として成り立つには困難である。 The power generation technology in the published literature cannot sufficiently convert the change in the tide into air pressure, and when the tide is stagnant, the power generation is interrupted, the structure and operation mechanism are complicated, and there is a huge amount of cave and huge tank facilities. It is expensive and it is difficult to relocate and move the facility.

本考案では、潮汐の全量を空気圧に効率よく変換するように潜函を設置、
潮汐停滞時でもタンクの圧縮空気を利用して連続発電し、さらに、装置の構造を簡明にして建造設置・運転管理の経済性と増設・移動も容易にできるよう配慮した。 In the present invention, a submersible is installed to efficiently convert the entire amount of tide to air pressure.
Even when the tide is stagnant, continuous power is generated using compressed air from the tank. Furthermore, the structure of the equipment is simplified so that the economics of construction and operation management and the expansion and movement can be facilitated.

即ち、本考案は、下部に海水流入流出溝を有する潜函を、潮汐による潜函内の海水量の変化を効率よく圧縮空気に変換するために、潜函下部は最大干潮時の海面の位置に、潜函上面は最大満潮時の海面の位置になるように設置し、満ち潮時に生じた圧縮空気を圧入貯蔵する圧縮空気タンクを潜函上に設置し、圧縮空気タンク内の圧縮空気で、圧縮空気利用タービンを回し、さらに引き潮時には負圧となった潜函へ流入する空気で負圧利用タービンを回し、切れ目なく発電を継続することを特徴とする潮汐発電装置である。 In other words, the present invention is designed to convert a submersible with a seawater inflow / outflow ditch at the bottom into a compressed air in order to efficiently convert the change in the amount of seawater in the submersible due to tides into compressed air. The upper surface is installed so that it is at the sea level at the time of maximum high tide, a compressed air tank that stores the compressed air generated during high tide is installed on the submersible, and the compressed air in the compressed air tank is used to install a compressed air turbine. The tidal power generator is characterized in that the power generation is continued without interruption by rotating the turbine using negative pressure with the air flowing into the submersible that has been turned to a negative pressure at the time of tide.

潮汐量の空気圧への変換が効率よく行われ、潮汐停滞時にも発電を中断することなく、建造設置・運転・管理が簡単で、経済的であり、施設規模の変更、増設・移動・移設も容易である。 Efficient conversion of tidal volume to air pressure, easy construction, operation and management without interruption of power generation even when tides are stagnant, economical, facility size change, expansion, movement and relocation Easy.

以下、本考案の実施例について、図面を参照して説明する。 Embodiments of the present invention will be described below with reference to the drawings.

満ち潮時に、潜函３内の海面の上昇により、潜函３内で圧縮された空気は、潜函の上部に設けた各々の圧縮空気タンク４に蓄えられる。蓄えられた圧縮空気は、圧縮空気送気管７を経由して、圧縮空気利用タービン１１を回転させ、連結した発電機を回転させることにより発電する。 FIG. 1 shows a left side view of the power generator of the present invention.
FIG. 2 shows a plan view of the power generator of the present invention.
At high tide, the air compressed in the submersible 3 due to the rise of the sea level in the submersible 3 is stored in each compressed air tank 4 provided on the top of the submersible. The stored compressed air is generated via the compressed air feed pipe 7 by rotating the compressed air utilization turbine 11 and rotating the connected generator.

引き潮時には、潜函３内の海面の下降により、潜函内が負圧になり、外部から流入する空気が、負圧空気利用タービン１２を回転させ、連結した発電機を回転させることにより発電する。タービンを回転させた流入空気は、負圧空気集中管１３及び負圧空気流入管１５を経由して潜函内に流入する。
引き潮が始まってしばらくの間は、圧縮空気タンク４に蓄えられた圧縮空気により発電が継続されるので、切れ目無く発電を継続することが出来る。 At the time of ebb tide, the sea level in the submersible 3 is lowered, and the inside of the submersible becomes negative pressure, and the air flowing in from the outside rotates the negative pressure air utilization turbine 12 and rotates the connected generator to generate power. The inflow air that has rotated the turbine flows into the submersible via the negative pressure air concentration pipe 13 and the negative pressure air inflow pipe 15.
Since power generation is continued by the compressed air stored in the compressed air tank 4 for a while after the ebb tide begins, power generation can be continued without interruption.
