Description

本発明は、水力発電装置に関するものである。   The present invention relates to a hydroelectric power generator.

近年、石油や石炭などの化石燃料の代替えエネルギーが注目される中、太陽光発電や風力発電の他にも水力発電が注目されており、例えば特開２００３−２８６９３５号のような水力を電気に変換する水力発電装置（以下、従来例）が種々提案されている。   In recent years, as alternative energy to fossil fuels such as oil and coal has attracted attention, hydroelectric power generation has attracted attention in addition to solar power generation and wind power generation. For example, hydroelectric power as disclosed in Japanese Patent Application Laid-Open No. 2003-286935 is used as electricity. Various hydroelectric generators (hereinafter, conventional examples) for conversion have been proposed.

この従来例は、河川の水流により回転力を得ることにより発電機を駆動して発電する発電装置と、この発電装置を搭載して河川の水面に浮かべる浮体装置と、川岸より浮体装置を牽引する牽引装置とを備えたものであり、この従来例であれば、河川の水位が変わっても発電することができる。   In this conventional example, a power generation device that generates power by driving a generator by obtaining a rotational force by a river flow, a floating device that is mounted on the water surface of the river with this power generation device, and pulls the floating device from the riverbank In this conventional example, power can be generated even if the water level of the river changes.

即ち、従来例は、水流を受けて発電機を駆動する回転力を得るための回転部は、所謂水車構造であって、その下方部分で水流を受けて回転する構造であるが、この従来例の回転部は、浮体装置で水面に浮くものであり、川岸などに固定されてはいないから、水位が変わっても常に下方部分が水没する状態が得られ、よって、回転することができ、河川の水位が変わっても発電することができる。   That is, in the conventional example, the rotating part for obtaining the rotational force that receives the water flow and drives the generator has a so-called water wheel structure, and is a structure that rotates by receiving the water flow at the lower part thereof. The rotating part of the floating body floats on the water surface with a floating body device and is not fixed to the riverbank etc., so even if the water level changes, the state where the lower part is always submerged is obtained. Even if the water level changes, power can be generated.

しかしながら、従来例は、前述したように川岸に係留して水上に浮かべるという構造上、例えば風が強くて波が高い場合に浮体装置が揺動して発電装置が良好に作動しない（回転部が良好に回転しない）など、安定的な発電が望めず、しかも、構造が複雑でコスト高であり、更に、従来例は水上で動くため、景観上好ましくなく、また、騒音が出るなど、周辺環境への問題が危惧される。   However, in the conventional example, as described above, moored on the river bank and floated on the water, for example, when the wind is strong and the waves are high, the floating body device swings and the power generation device does not operate well (the rotating part does not work well). Stable power generation is not possible, and the structure is complicated and expensive. In addition, the conventional example moves on the water, which is undesirable in terms of scenery, and noise is generated in the surrounding environment. There are concerns about problems.

また、従来例は、発電機が水に濡れて壊れ易いという問題点もある。   Further, the conventional example also has a problem that the generator is easily damaged by getting wet with water.

本発明者は、前述した水力発電装置について更なる研究・開発を進め、その結果、極めて商品価値の高い画期的な水力発電装置を開発した。   The present inventor has further researched and developed the above-described hydroelectric generator, and as a result, has developed an innovative hydroelectric generator with extremely high commercial value.

好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。   An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

例えば河川の水中に回転部１を水没状態で配すると、水流を受けて回転部１は回転し、この回転部１の回転により発電部２で発電が行われる。   For example, when the rotating unit 1 is placed in the water of a river in a submerged state, the rotating unit 1 rotates in response to a water flow, and the power generation unit 2 generates power by the rotation of the rotating unit 1.

この回転部１の回転について説明すると、流速変更部６により、回転体５を回転軸部３を境界として２分した際の一側の領域Ｐ１におけるハネ体４に当接する水流の流速と、他側の領域Ｐ２におけるハネ体４に当接する水流の流速とが異ならしめられ、具体的には、一側の領域Ｐ１の上流側に配される流速減少部７の遮水面部７ａにより、一側の領域Ｐ１への水流は遮られて流速が減少し、一方、他側の領域Ｐ２の上流側に配される流速増加部８の水流絞り部８ａにより、他側の領域Ｐ２への水流は絞られて流速が増加する。   The rotation of the rotating unit 1 will be described. The flow rate changing unit 6 divides the rotating body 5 into two parts with the rotating shaft part 3 as a boundary. The flow velocity of the water flow abutting against the rod body 4 in the region P2 on the side is made different, specifically, the water-impervious surface portion 7a of the flow velocity reduction portion 7 arranged on the upstream side of the region P1 on the one side The water flow to the region P1 is blocked and the flow velocity is reduced, while the water flow to the other region P2 is restricted by the water flow restricting portion 8a of the flow velocity increasing portion 8 arranged on the upstream side of the other region P2. As a result, the flow rate increases.

この領域Ｐ１，Ｐ２夫々への水流の流速差により、回転部１は水中に没した状態であっても回転する。   Due to the difference in flow velocity of the water flow to each of the regions P1 and P2, the rotating unit 1 rotates even when it is immersed in water.

つまり、回転体５に設けられた各ハネ体４は、回転体５の回転位置に応じて、一側の領域Ｐ１にて遅い流速の水流を受けるときと、他側の領域Ｐ２にて早い流速の水流を受けるときとが切り替わることになる為、回転部１は連続して回転する。   That is, each of the splash bodies 4 provided in the rotator 5 receives a slow water flow in the region P1 on one side and a fast flow rate in the region P2 on the other side according to the rotational position of the rotator 5. Therefore, the rotating unit 1 rotates continuously.

従って、本発明は、前述した構造を具備することで、回転部１は水中に没した状態で回転するから、例えば渇水時期などを考慮して常に水中に没する位置に配置しておけば常に発電させることができ、しかも、水中は風や波の影響を受けにくいため、この点においても安定的に発電が行われることになる。   Accordingly, the present invention is provided with the above-described structure, so that the rotating unit 1 rotates in a state where it is immersed in water. For example, if it is always placed in a position where it is immersed in water in consideration of drought time, etc. Electricity can be generated, and underwater is not easily affected by wind and waves, so that power can be generated stably in this respect.

また、本発明は、前述した作動が回転部１の上流側位置に流速変更部６を配するだけの簡易構造で達成され、コスト安であり、また、回転部１を水中に没した状態とすることができるから、景観を悪くすることなく、騒音も出ないなど、周辺環境への問題も可及的に抑制することができる。   In addition, the present invention is achieved with a simple structure in which the above-described operation is simply provided with the flow velocity changing unit 6 at the upstream position of the rotating unit 1, is inexpensive, and the rotating unit 1 is submerged in water. Therefore, it is possible to suppress the problems to the surrounding environment as much as possible without deteriorating the scenery and no noise.

本発明の具体的な一実施例について図面に基づいて説明する。   A specific embodiment of the present invention will be described with reference to the drawings.

本実施例は、水流により回転する回転部１と、この回転部１の回転により発電する発電部２とを有する水力発電装置である。   The present embodiment is a hydraulic power generation apparatus having a rotating unit 1 that is rotated by a water flow and a power generating unit 2 that generates power by the rotation of the rotating unit 1.

以下、本実施例に係る構成各部について詳細な説明をする。   Hereinafter, each component according to the present embodiment will be described in detail.

回転部１は、図１，２に図示したように後述する発電部２に設けられる回転軸部３の放射方向位置にして互いに等間隔の回転角度位置に複数のハネ体４が正面視環状に並設された構成である。   As shown in FIGS. 1 and 2, the rotating unit 1 includes a plurality of rod bodies 4 in an annular shape in front view at radial positions of a rotating shaft unit 3 provided in a power generation unit 2 to be described later at equal rotation angle positions. It is the structure arranged side by side.

具体的には、発電部２から延設される回転軸部３の先端部に該回転軸部３の回転とともに回転する合成樹脂製（強化プラスチック製）の回転体５を設け、この回転体５の正面部及び背面部夫々の回転方向に等間隔となる複数位置に合計１６のハネ体４が設けられている。   Specifically, a rotating body 5 made of synthetic resin (made of reinforced plastic) that rotates with the rotation of the rotating shaft portion 3 is provided at the tip of the rotating shaft portion 3 extending from the power generation unit 2. A total of 16 rod bodies 4 are provided at a plurality of positions at equal intervals in the rotation direction of each of the front part and the rear part.

本実施例では回転体５を円形板状としたが、回転軸部３から放射方向にハネ体４の数だけアーム状の部材が突出する構造（骨組み構造）でも良い。   In the present embodiment, the rotating body 5 has a circular plate shape, but may have a structure (frame structure) in which arm-shaped members protrude from the rotating shaft portion 3 in the radial direction by the number of the rod bodies 4.

ハネ体４は、合成樹脂製（強化プラスチック製）で型成形したものであり、正面視Ｌ字形状の細板状に形成されている。   The spring body 4 is made of synthetic resin (made of reinforced plastic) and is formed into a thin plate shape having an L shape in front view.

このハネ体４は、図２に図示したように回転体５の正面部及び背面部夫々の周端部にして対称位置に止着部材９を貫通させて一体に連結されている。   As shown in FIG. 2, the spring body 4 is integrally connected to the circumferential end portions of the front surface portion and the back surface portion of the rotating body 5 through the fastening member 9 at symmetrical positions.

また、この各ハネ体４は、夫々回転方向へ向けて凸をなすように先鋭先端部が同一方向に向けて設けられている。   In addition, each of the rod bodies 4 is provided with a sharp tip end in the same direction so as to protrude toward the rotation direction.

従って、各ハネ体４は、回転体５（回転部１）を回転軸部３を境界として２分した対向する領域のうち、後述する流速変更部６により水流の流速が遅くなった一側の領域Ｐ１に位置する場合には、凸状となる外面で抵抗が少ない状態で水流を受けることになり、一方、水流の流速が早くなった他側の領域Ｐ２に位置する場合には、凹状となる内面で抵抗が大きい状態で水流を受けることになり、よって、この水流の流速が遅く且つ水流の抵抗が小さくなる一側の領域Ｐ１に位置するハネ体４と、水流の流速が早く且つ水流の抵抗が大きくなる他側の領域Ｐ２に位置するハネ体４との間で生じる回転力の差により、回転体５を一方向に回転させる作用が生じることになる。   Accordingly, each of the splash bodies 4 is located on the one side where the flow velocity of the water flow is slowed down by the flow velocity changing section 6 described later in the opposed region of the rotating body 5 (rotating portion 1) divided into two with the rotating shaft portion 3 as a boundary. When located in the region P1, the water flow is received with a low resistance on the outer surface that is convex, while when located in the other region P2 where the flow velocity of the water flow is increased, the concave shape In this way, the inner surface receives a water flow in a state where the resistance is high, and thus the flow rate of the water flow is low and the flow rate of the water flow is high and the flow rate of the water flow is high. The effect of rotating the rotating body 5 in one direction is caused by the difference in rotational force generated between the spring body 4 located in the other region P2 where the resistance of the rotating body 5 increases.

また、回転部１は強化プラスチック製故に軽量であり、良好に回転する。   Moreover, since the rotation part 1 is a reinforced plastic, it is lightweight and rotates well.

また、回転軸部３は、その中央部位を軸受部13で回動自在に軸受されており、左右の端部夫々が軸受部13から外部に突出する状態に設けられている。尚、この軸受部13には図示省略のベアリングが設けられている。   Further, the rotary shaft portion 3 is rotatably supported at its central portion by a bearing portion 13 and is provided in a state in which left and right end portions protrude from the bearing portion 13 to the outside. The bearing portion 13 is provided with a bearing (not shown).

また、この回転軸部３の一端部には前述したように回転部１が設けられ、他端部には発電部２が設けられている。   Further, as described above, the rotating portion 1 is provided at one end portion of the rotating shaft portion 3, and the power generating portion 2 is provided at the other end portion.

この発電部２は、図１に図示したように回動軸部３の端部に複数の発電機11（タービン）を連設したものであり、回動軸部３に大径ギア14を設け、この大径ギア14と係合する小径ギア15を各発電機11に設けたものである。尚、大径ギア15の径は回転体５の径と同一（若しくはそれよりも大きな径）となるように設定されている。   As shown in FIG. 1, the power generation unit 2 includes a plurality of generators 11 (turbines) connected to the end of the rotation shaft 3, and a large-diameter gear 14 is provided on the rotation shaft 3. Each generator 11 is provided with a small-diameter gear 15 that engages with the large-diameter gear 14. The diameter of the large-diameter gear 15 is set to be the same as (or larger than) the diameter of the rotating body 5.

従って、回転部１の回転により回転軸部３が回転することで各発電機11は発電する。   Therefore, each generator 11 generates electric power by rotating the rotating shaft portion 3 by the rotation of the rotating portion 1.

また、発電部２は、各発電機11が防水性を有するボックス10内に設けられ、この発電部２は地下に埋設されている。   Further, the power generation unit 2 is provided in a box 10 in which each generator 11 is waterproof, and this power generation unit 2 is buried underground.

従って、この発電部２を実際に川岸などに設置した状態において景観を悪くすることなく、騒音も出ないなど、周辺環境への問題も可及的に抑制することができる。   Therefore, it is possible to suppress problems to the surrounding environment as much as possible, such as no deterioration of the scenery and no noise when the power generation unit 2 is actually installed on the riverbank.

符号16はボックス８内の空気や湿気を排気する排気筒である。   Reference numeral 16 denotes an exhaust pipe for exhausting air and moisture in the box 8.

本実施例では、回転体５（回転部１）を正面方向から見た際における回転軸部３を境界として２分した対向する領域のうち、一側の領域Ｐ１におけるハネ体４に当接する水流の流速（圧）と、他側の領域Ｐ２におけるハネ体４に当接する水流の流速（圧）を異ならしめる流速変更部６が設けられている。   In the present embodiment, the water flow that abuts on the spring body 4 in the region P1 on one side among the opposing regions divided by the rotation shaft portion 3 as a boundary when the rotating body 5 (rotating portion 1) is viewed from the front. The flow velocity changing section 6 is provided for differentiating the flow velocity (pressure) of the water flow and the flow velocity (pressure) of the water flow in contact with the splash body 4 in the region P2 on the other side.

この流速変更部６は、一側の領域Ｐ１の上流側に配され水流を遮る遮水面部７ａを有し該遮水面部７ａにより該水流の流速を減少せしめる流速減少部７と、他側の領域Ｐ２の上流側に配され水流を絞る水流絞り部８ａを有し該水絞り部８ａにより該水流の流速を増加せしめる流速増加部８とで構成されている。   The flow rate changing unit 6 has a water blocking surface portion 7a arranged on the upstream side of the region P1 on one side to block the water flow, and a flow rate reducing portion 7 for decreasing the flow velocity of the water flow by the water blocking surface portion 7a, and It has a water flow restricting portion 8a that is arranged upstream of the region P2 and restricts the water flow, and is configured by a flow velocity increasing portion 8 that increases the flow velocity of the water flow by the water restricting portion 8a.

具体的には、図１，３に図示したように合成樹脂製（強化プラスチック製）の縦長形状の枠体17を設け、この枠体17の下方部位に流速減少部７を設けるとともに、上方部位に流速増加部８を設けている。尚、この枠体17内に前述した回転部１も配設され、また、枠体17の背面部はコンクリート製の護岸壁20に沿設状態に設けられる。   Specifically, as shown in FIGS. 1 and 3, a vertically long frame 17 made of synthetic resin (made of reinforced plastic) is provided, and a flow velocity reduction portion 7 is provided in a lower part of the frame 17 and an upper part. Is provided with a flow velocity increasing portion 8. In addition, the rotary part 1 mentioned above is also arrange | positioned in this frame 17, and the back part of the frame 17 is provided in the state along the revetment wall 20 made from concrete.

流速減少部７は、図３に図示したように適宜な合成樹脂製（強化プラスチック製）の部材で形成された板状体であり、枠体17の下部に垂直状態に設けられている。   As shown in FIG. 3, the flow velocity reduction portion 7 is a plate-like body formed of an appropriate synthetic resin (reinforced plastic) member, and is provided in a vertical state below the frame body 17.

この流速減少部７の上端部は回転軸部３が配される位置まで達する高さに設定されている。   The upper end portion of the flow velocity reduction portion 7 is set to a height that reaches the position where the rotary shaft portion 3 is disposed.

従って、流速減少部７は、水流を受けた際、水流を遮水面部７ａで受けて水流の流速を減少せしめることになる。   Therefore, when receiving the water flow, the flow velocity reduction unit 7 receives the water flow at the impermeable surface portion 7a and decreases the flow velocity of the water flow.

流速増加部８は、図３に図示したように適宜な合成樹脂製の部材（強化プラスチック）で形成された筒状体であり、一端部に水導入口部８ｂが設けられ他端部に水導出口部８ｃが設けられている。   The flow velocity increasing portion 8 is a cylindrical body formed of an appropriate synthetic resin member (reinforced plastic) as shown in FIG. 3, and has a water inlet 8b at one end and water at the other end. A lead-out port 8c is provided.

また、流速増加部８は内孔径が径小となるよう、下流側程径小となるように構成されており、即ち、テーパー内孔であり、水流を絞って流速を上げる水流絞り部８ａが設けられている。   Further, the flow velocity increasing portion 8 is configured to have a smaller diameter toward the downstream side so that the inner hole diameter becomes smaller, that is, a tapered inner hole, and a water flow restricting portion 8a that restricts the water flow to increase the flow velocity. Is provided.

また、流速増加部８は水導出口部８ｃが上向きになるように枠体17に配設されている。   Further, the flow velocity increasing portion 8 is disposed on the frame body 17 so that the water outlet port portion 8c faces upward.

この流速増加部８は、水導出口部８ｃを水平方向に向けたり下向きになるように枠体17に対して可動自在（回動自在）に設けても良い。   The flow velocity increasing portion 8 may be provided so as to be movable (rotatable) with respect to the frame body 17 so that the water outlet port portion 8c is directed horizontally or downward.

尚、枠体17の上部に流速減少部７を設け、下端部に流速増加部８を設けるようにしても良い。この場合、ハネ体４の向きを図３に図示した場合と逆方向に向けるようにする。   In addition, the flow velocity decreasing part 7 may be provided in the upper part of the frame 17, and the flow velocity increasing part 8 may be provided in the lower end part. In this case, the direction of the spring body 4 is directed in the direction opposite to that shown in FIG.

符号18は転倒防止用の支持部材，19は枠体17の正面部下方位置に設けられ、ゴミや土砂などの流動物の侵入を防止する防護板体であり、この防護板体19は枠体17の背面部下方位置にも設けても良い。   Reference numeral 18 is a support member for preventing the fall, and 19 is a protective plate provided at a position below the front portion of the frame 17 to prevent intrusion of fluids such as dust and earth and sand. The protective plate 19 is a frame. You may provide also in 17 back part lower position.

以上の構成から成る本実施例に係る水力発電装置は、発電部２を川岸の地下に埋設状態とし、回転部１を河川の水中に没した状態とし、この回転部１の水流上流位置に流速変更部６を設置する。この水力発電装置の近傍にして地上には変電所が設置され、この変電所から水力発電装置で発生した電気は送電線で送電される。   In the hydroelectric power generator according to the present embodiment having the above-described configuration, the power generation unit 2 is buried in the basement of the riverbank, and the rotation unit 1 is submerged in the river water. A change unit 6 is installed. A substation is installed on the ground in the vicinity of this hydroelectric generator, and electricity generated by the hydroelectric generator from this substation is transmitted through a transmission line.

本実施例は上述のように構成したから、流速変更部６により、回転体５を回転軸部３を境界として２分した際の一側の領域Ｐ１におけるハネ体４に当接する水流の流速と他側の領域Ｐ２におけるハネ体４に当接する水流の流速が異ならしめられ、具体的には、一側の領域Ｐ１の上流側に配される流速減少部７の遮水面部７ａにより、一側の領域Ｐ１を流れる水流は遮られて流速が減少し、一方、他側の領域Ｐ２の上流側に配される流速増加部８の水流絞り部８ａにより、他側の領域Ｐ２を流れる水流は絞られて流速が増加する。   Since the present embodiment is configured as described above, the flow velocity changing unit 6 divides the rotating body 5 into two parts with the rotating shaft portion 3 as a boundary, and the flow velocity of the water flow contacting the splash body 4 in the region P1 on one side The flow velocity of the water flow in contact with the spring body 4 in the other region P2 is made different, specifically, the water-impervious surface portion 7a of the flow velocity reducing portion 7 arranged upstream of the one region P1 The flow of water flowing through the region P1 is blocked and the flow velocity is reduced. On the other hand, the flow of water flowing through the region P2 on the other side is restricted by the water flow restricting portion 8a of the flow velocity increasing portion 8 arranged on the upstream side of the other region P2. As a result, the flow rate increases.

この領域Ｐ１，Ｐ２夫々への水流の流速差により、回転部１は水中に没した状態であっても回転する。   Due to the difference in flow velocity of the water flow to each of the regions P1 and P2, the rotating unit 1 rotates even when it is immersed in water.

この回転部１の回転により回転軸部３が回転し、この回転軸部３の回転により発電部２（発電機11）が作動して発電する。   The rotation shaft 3 is rotated by the rotation of the rotation unit 1, and the power generation unit 2 (the generator 11) is operated by the rotation of the rotation shaft 3 to generate power.

よって、本実施例によれば、前述した構造を具備することで、回転部１は水中に没した状態で回転させることができるから、例えば渇水時期などを考慮して常に水中に没する位置に配置しておけば常に発電させることができ、しかも、水中は風や波の影響を受けにくいため、この点においても安定的に発電が行われることになる。   Therefore, according to the present embodiment, by providing the above-described structure, the rotating unit 1 can be rotated in a state of being submerged in water. If it is arranged, it can always generate electric power, and since it is hardly affected by wind and waves in the water, stable electric power generation is also performed in this respect.

また、本実施例は、前述した作動が回転部１の上流側位置に流速変更部６を配するだけの簡易構造で達成され、コスト安であり、また、回転部１を水中に没した状態とすることができるから、景観を悪くすることなく、騒音も出ないなど、周辺環境への問題も可及的に抑制することができる。   Further, in the present embodiment, the above-described operation is achieved with a simple structure in which the flow velocity changing unit 6 is disposed at the upstream side position of the rotating unit 1, the cost is low, and the rotating unit 1 is submerged in water. Therefore, it is possible to suppress problems to the surrounding environment as much as possible without deteriorating the scenery and no noise.

また、本実施例は、流速増加部８は、一端部に水導入口部８ｂが設けられ他端部に水導出口部８ｃが設けられた筒状体であり、この筒状体には、内孔径を径小とすることで水流を絞る水流絞り部８ａが設けられ、更に、この水流絞り部８ａは、下流側程径小となるテーパー内孔であるから、確実に水流の流速を増加させることができる。   Further, in this embodiment, the flow velocity increasing portion 8 is a cylindrical body in which a water inlet port portion 8b is provided at one end portion and a water outlet port portion 8c is provided in the other end portion. A water flow restricting portion 8a for restricting the water flow is provided by reducing the diameter of the inner hole. Further, since the water flow restricting portion 8a is a tapered inner hole whose diameter decreases toward the downstream side, the flow velocity of the water flow is reliably increased. Can be made.

また、本実施例は、ハネ体４は回転方向へ向けて凸をなす正面視Ｌ字形状に形成されているから、各ハネ体４は回転体５の回転位置に応じて水流の抵抗が大きい場面と水流の抵抗が小さい場面とが確実に得られることになり、流速変更部６による水流の流速差に加え、水流の抵抗差によっても回転体５を回転する作用が生じ、よって、回転部１における良好な回転が達成される。   Further, in the present embodiment, the splash bodies 4 are formed in an L-shape in a front view that protrudes in the rotation direction, so that each splash body 4 has a large resistance to water flow according to the rotational position of the rotary body 5. The scene and the scene where the resistance of the water flow is small are surely obtained, and in addition to the difference in the flow velocity of the water flow by the flow velocity changing unit 6, the action of rotating the rotating body 5 is also generated by the difference in the resistance of the water flow. A good rotation at 1 is achieved.

また、本実施例は、回転部１（ハネ体４及び回転体５），枠体17，流速増加部８及び流速減少部７はいずれも強化プラスチックで構成されており、強度が高く且つ錆ないなどの高い耐久性を有することになる。   In this embodiment, the rotating part 1 (sheath body 4 and rotating body 5), the frame body 17, the flow velocity increasing portion 8 and the flow velocity decreasing portion 7 are all made of reinforced plastic and have high strength and no rust. It will have high durability.

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。   Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
