Description

動力源増幅発電システムPower source amplification power generation system
　本発明は、発電システムに関するものである。 The present invention relates to a power generation system.
　近年、サステナビリティ（持続可能）社会の実現に向けて、環境負荷の小さなエネルギー源に注目が集まっている。原子力発電は、ＣＯ２を排出しないためベースロード電源として期待されていたが、核分裂反応に伴い発生する高レベル放射性廃棄物の処理問題は解決しておらず、多くの懸念事項が先送りされている。 In recent years, energy sources with low environmental impact have been attracting attention in order to realize a sustainable society. Nuclear power generation was expected to be a base-load power source because it does not emit CO2, but the problem of disposing of high-level radioactive waste generated by nuclear fission reactions has not been resolved, and many concerns have been postponed.
　このため各国とも自然エネルギー、特に太陽光発電や風力発電等へ依存度を高めている（例えば下記特許文献１参照）。しかしながら、特に風力発電は出力の大きな変動が避けられないため、発電効率の変動が大きい。具体的には発電機自体の効率が、ブレードの回転数によって大きく変動してしまう。したがって風力発電機のナセルと呼ばれる部分には、変速機構と発電機が内蔵されているが、変速機構が複雑な構成であると発電システム全体として高価になり、特に発展途上国における導入は難しくなる。 For this reason, each country is increasing its dependence on natural energy, especially solar power generation and wind power generation (see, for example, Patent Document 1 below). However, especially in wind power generation, large fluctuations in output are unavoidable, so power generation efficiency fluctuates widely. Specifically, the efficiency of the generator itself varies greatly depending on the number of rotations of the blades. Therefore, the part called the nacelle of a wind power generator has a built-in transmission mechanism and generator, but if the transmission mechanism has a complicated configuration, the entire power generation system becomes expensive and difficult to introduce, especially in developing countries. .
特許７０１９１５９号公報Patent No. 7019159
　発電システムにおいては、原動機と発電機の回転速度のマッチングが発電効率を決めるため、変速機構が極めて重要になる。しかし変速機構を構成するスプロケットが巨大になると、その重量は例えば数トンにも及ぶことになり、その慣性モーメントも巨大になるため、変速機構における損失が無視できなくなる。また直径が１０ｍを越えるような巨大で十分な強度を持った歯車を作製するには、高度な加工技術が必要になる。 In power generation systems, the matching of the rotational speeds of the prime mover and generator determines power generation efficiency, so the transmission mechanism is extremely important. However, if the sprocket that makes up the transmission mechanism becomes huge, its weight will reach, for example, several tons, and its moment of inertia will also become enormous, so losses in the transmission mechanism cannot be ignored. In addition, advanced processing technology is required to manufacture gigantic gears with a diameter of more than 10 meters and sufficient strength.
本発明では、このような課題に鑑み、大型であっても軽量、且つ、十分な強度を持ち、簡便に作製でき、安価な変速機構とそれを用いた高効率な発電システムを提供しようとするものである。 In view of these problems, the present invention aims to provide a large-sized yet lightweight transmission mechanism that has sufficient strength, can be easily manufactured, and is inexpensive, and a highly efficient power generation system using the same. It is something.

Grooves 62 and 63 having a semi-cylindrical side surface shape that can be fitted into (preferably half of the circumference) are formed.
２本のワイヤ１００はそれぞれ、その延伸方向及び周方向の一部が溝６２，６３に嵌合するようにして設けられる。これによりワイヤ１００の逸脱を防ぐことができる。なお、この状態においては、押圧部材６０とワイヤ１００とは、大スプロケット１０の径方向に一部重複することになる。本発明の第二実施形態に係る変速機構５の他の特徴については第一実施形態と同様であるため、記載を省略する。 The two wires 100 are provided so that a portion of the wires in the extending direction and in the circumferential direction fit into the grooves 62 and 63, respectively. This can prevent the wire 100 from coming off. In this state, the pressing member 60 and the wire 100 partially overlap in the radial direction of the large sprocket 10.

A similarly configured prime mover is arranged symmetrically to prime mover 30.
このようにして、本発明の第五実施形態においては、同軸（軸２５）上に配置された複数の原動機が同時に稼働するものとする。なお、この場合、発電機４０において発電した電力の一部は、各原動機にそれぞれ送電されることになる。 In this way, in the fifth embodiment of the present invention, it is assumed that a plurality of prime movers arranged on the same axis (shaft 25) operate simultaneously. In this case, a portion of the power generated by the generator 40 will be transmitted to each prime mover.
このようにすることで、より大型の発電機４０を駆動することができるという優れた効果を奏する。 By doing so, it is possible to drive a larger generator 40, which is an excellent effect.
また、本発明の第六実施形態に係る動力源増幅発電システムは、発電機４０の中心軸４３を、大スプロケット１０を貫通するようにして延伸させ、その軸４３の反対側端部において、発電機４０と同様の構成の発電機を、発電機４０と対称的に配置する。 Further, in the power source amplification power generation system according to the sixth embodiment of the present invention, the central shaft 43 of the generator 40 is extended to pass through the large sprocket 10, and the power generation is performed at the opposite end of the shaft 43. A generator having the same configuration as the generator 40 is arranged symmetrically with the generator 40.
さらには、延伸させた軸４３上に、複数（４以上の偶数）個の発電機を連結させてもよい。いずれにしても、軸４３の中心に大スプロケット１０が配置（固定）され、この大スプロケット１０を中心にして軸４３の両側に同数の発電機を配置するものとする。なお、各発電機間にはカップリングが設けられる。 Furthermore, a plurality of (an even number of 4 or more) generators may be connected on the extended shaft 43.

発電機が一つの場合、単体で２００ｔにも及ぶこともある。そのため陸上輸送が困難であり、用途が洋上風力発電に限定されてしまうことが多い。また、その架設費用も莫大である。しかし、上述のようにして発電機を複数とすることで、一つ一つの発電機の外径の寸法及び重量を抑えることができ、発電機を小型化することができ（例えば重量が２５ｔ以下など）、陸上での利用が可能となる。また、通常のコンテナ輸送が可能であり、輸送コストを格段に抑えることができる。 If there is only one generator, it can weigh up to 200 tons. For this reason, land transportation is difficult, and applications are often limited to offshore wind power generation. Moreover, the construction cost is enormous. However, by using multiple generators as described above, the outer diameter and weight of each generator can be reduced, making it possible to downsize the generator (for example, the weight is 25 tons or less). ), it can be used on land. In addition, normal container transportation is possible, and transportation costs can be significantly reduced.

さらに、電気モータの定格回転を１８００回転に設定することで、減速比を１００～１２０分の１にでき、電気モータのトルクを１００～１２０倍に増幅することができる。 Furthermore, by setting the rated rotation of the electric motor to 1800 rotations, the reduction ratio can be reduced to 1/100 to 120, and the torque of the electric motor can be amplified 100 to 120 times.
また、本発明の第八実施形態に係る動力源増幅発電システムは、本発明の第六実施形態のように複数の発電機を設ける様にした場合、これら発電機を堅牢な地盤上に組み立てられた台の上に設けるようにする。このようにすることで、発電機がナセルである場合、低周波振動もなく騒音もない、自然破壊をせず、発電稼働することができる。 Furthermore, when the power source amplification power generation system according to the eighth embodiment of the present invention is provided with a plurality of generators as in the sixth embodiment of the present invention, these generators can be assembled on a solid ground. It should be placed on a table. By doing so, when the generator is a nacelle, it is possible to generate electricity without causing low-frequency vibrations, noise, or natural destruction.
大スプロケット１０は、直径６～１０ｍ程度の大きさになるが、分解して運搬することで通常の運搬の仕方で対応できるので、２００坪程度の平地ならどこでも設置することができる。即ち自然破壊をすることなく普及することができるのである。 Although the large sprocket 10 has a diameter of about 6 to 10 m, it can be disassembled and transported in the normal way, so it can be installed anywhere on flat land of about 200 tsubo. In other words, it can be spread without destroying nature.
尚、本発明の変速機構、及び、動力源増幅発電システムは、上記した実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。 It should be noted that the transmission mechanism and power source amplification power generation system of the present invention are not limited to the embodiments described above, and it goes without saying that various changes can be made without departing from the gist of the present invention. .
