第１収集管２１を図３（ａ）、図３（ｂ）に示す。図３（ａ）は、第１収集管２１の平面図、図３（ｂ）は、側面図である。第１収集管２１は、川の流れ１５の上流側に広く開口し、川の流れの下流側に狭く開口した筒である。入口側に第１直線部２１ｂ、出口側に第２直線部２１ｃと、があり、両者と繋ぐ傾斜部２１ａがある。The first collection tube 21 is shown in FIGS. 3 (a) and 3 (b). FIG. 3A is a plan view of the first collection tube 21, and FIG. 3B is a side view. The first collection pipe 21 is a cylinder having a wide opening on the upstream side of the river flow 15 and a narrow opening on the downstream side of the river flow. There is a first straight line portion 21b on the inlet side and a second straight line portion 21c on the exit side, and there is an inclined portion 21a connecting the two.

第１直線部２１ｂ、第２直線部２１ｃは、円筒であり、空洞の断面積は、第１直線部２１ｂが第２直線部２１ｃより大きい。
傾斜部２１ａは、中の空洞の断面積が、入口側から出口側へ徐々に小さくなる。
第２直線部２１ｃには、第１整流部２５が配置されている。
第１整流部２５は、円柱板に、円柱の貫通穴が複数設けられている。第１整流部２５（第２整流部２６）は、ゴミやコケなどで流れが悪くなるので、交換できるように、第１取集管２１、第１管３１、第２取集管２２、第２管３２には、それぞれ交換部１２があり、
交換できる。交換部１２は蓋であり、蓋を開け閉めして第１整流部２５を交換する。または、交換部１２は、開口であり、第１整流部２５をはめ込みセットし、開口が閉じ、第１整流部２５を開口から外し交換してもよい。第２収集菅２２も、第１収集管２１と同様の構造である。The first straight line portion 21b and the second straight line portion 21c are cylindrical, and the cross-sectional area of the cavity of the first straight line portion 21b is larger than that of the second straight line portion 21c.

A first rectifying unit 25 is arranged in the second straight line unit 21c.
The first rectifying unit 25 is provided with a plurality of cylindrical through holes in the cylindrical plate. Since the flow of the first rectifying unit 25 (second rectifying unit 26) becomes poor due to dust, moss, etc., the first collecting pipe 21, the first pipe 31, the second collecting pipe 22, and the second collecting pipe 22 can be replaced. The 2 pipes 32 each have an exchange portion 12.
Can be exchanged. The replacement unit 12 is a lid, and the lid is opened and closed to replace the first rectifying unit 25. Alternatively, the replacement unit 12 is an opening, and the first rectifying unit 25 may be fitted and set, the opening may be closed, and the first rectifying unit 25 may be removed from the opening and replaced. The second collection tube 22 also has the same structure as the first collection tube 21.

図３（ｃ）は、第１収集菅２１の別例である。第１整流部２５が異なる。図３（ｄ）に、その第１整流部２５の断面積を示す。貫通する開口６０がある。開口６０は、中央より周辺で密度が多い。開口６０の開口率が周辺ほど大きい。 FIG. 3C is another example of the first collecting tube 21. The first rectifying unit 25 is different. FIG. 3D shows the cross-sectional area of the first rectifying unit 25. There is an opening 60 that penetrates. The opening 60 has a higher density in the periphery than in the center. The aperture ratio of the opening 60 is larger toward the periphery.

また、図３（ｅ）に別の第１整流部２５の断面図を示す。開口６０の上部、水の入り口側に絞り部６１があり、開口断面が小さくなる。その後、開口断面が一定の層流部６２がある。絞り部６１で水を集め、層流部６２で、水を層流にする。より層流になる。 Further, FIG. 3 (e) shows a cross-sectional view of another first rectifying unit 25. There is a throttle portion 61 at the upper part of the opening 60 and on the water inlet side, and the opening cross section becomes smaller. After that, there is a laminar flow portion 62 having a constant opening cross section. Water is collected at the squeezing section 61, and the water is laminarized at the laminar flow section 62. It becomes more laminar.

第１管３１は、円筒で、空洞の断面積は一定である。図４（ａ）に第１管３１の側面図、図４（ｂ）に平面図を示す。固定部５１に固定されるための留め部の対応部５４がある。 The first pipe 31 is a cylinder, and the cross-sectional area of the cavity is constant. FIG. 4A shows a side view of the first pipe 31, and FIG. 4B shows a plan view. There is a corresponding portion 54 of the fastening portion for being fixed to the fixing portion 51.

第２収集管２２は、第１収集管２１と同様の形状で、内側の空洞の径が小さい。
第２管３２は、第１管３１と同様の形状で、空洞の径が小さい。The second collection tube 22 has the same shape as the first collection tube 21, and the diameter of the inner cavity is small.
The second pipe 32 has the same shape as the first pipe 31 and has a small cavity diameter.

発電機４１は、羽根４２を有し、羽根４２は、第２管３２内にすべて含まれる。ただし、羽根４２以外の本体部分は、第２管３２にない。発電機４１は、水面より上へケーブル６５で接続されている。電力を水面より上へ送ることができる。ケーブル６５を介して、発電機４１の制御、診断、メンテナンスができる。 The generator 41 has blades 42, and the blades 42 are all included in the second pipe 32. However, the main body portion other than the blade 42 is not in the second pipe 32. The generator 41 is connected above the water surface by a cable 65. Electricity can be sent above the surface of the water. The generator 41 can be controlled, diagnosed, and maintained via the cable 65.

固定具５１は、第１管３１、第２管３２、発電機４１のそれぞれを河底１１に固定している。図５（ａ）に固定部５１の正面図、図５（ｂ）に側面図を示す。開口部５３があり、留め部５２がその開口内で移動できる。留め部５３は、固定部５１と第１管３１、第２管３２、発電機４１との間を固定する。開口部５３により固定位置を調整できる。 The fixture 51 fixes each of the first pipe 31, the second pipe 32, and the generator 41 to the riverbed 11. FIG. 5A shows a front view of the fixing portion 51, and FIG. 5B shows a side view. There is an opening 53, and the fastening 52 can move within the opening. The fastening portion 53 fixes between the fixing portion 51 and the first pipe 31, the second pipe 32, and the generator 41. The fixed position can be adjusted by the opening 53.

第１管３１と第２管３２の中心線６０が、水面１０に平行となるように、固定部５１で調整される。山の上部では、水面が傾斜している。その場合は、その水面に平行にする。
河底１１は、河川の底である。The center line 60 of the first pipe 31 and the second pipe 32 is adjusted by the fixing portion 51 so as to be parallel to the water surface 10. At the top of the mountain, the water surface is sloping. In that case, make it parallel to the water surface.
The river bottom 11 is the bottom of the river.

＜プロセス＞
図２で水の流れを説明する。第１収集管２１で水を集める。傾斜部２１ａにより、水の流れの方向が変わり渦流２４となる。中心付近の水は、方向を変えず層流２３として取集される。第１整流部２５により、水は層流２３となる。層流２３は、第１管３１を進む。<Process>
The flow of water will be described with reference to FIG. Water is collected in the first collection pipe 21. The inclined portion 21a changes the direction of the water flow to form a vortex flow 24. The water near the center is collected as a laminar flow 23 without changing the direction. The first rectifying unit 25 causes the water to become a laminar flow 23. The laminar flow 23 advances through the first pipe 31.

第２収集管２２に層流２３が達する。第１取集管２１と同様に、渦流２４が発生するが、第２整流部２６により、水は層流２３となる。層流２３は、第２管３２を進む。
層流２３は、第２管３２の端部の内側の羽根４２を回転させる。その後、開放系へ水は開放される。The laminar flow 23 reaches the second collection pipe 22. Similar to the first collection pipe 21, a vortex flow 24 is generated, but the second rectifying unit 26 causes the water to become a laminar flow 23. The laminar flow 23 advances through the second pipe 32.
The laminar flow 23 rotates the blade 42 inside the end of the second pipe 32. After that, the water is released to the open system.

（１）大きな径の第１管３１、開口を広げた第１収集管２１で多くの水を集め、層流２３で羽根４２を回転させるので、効率的に発電できる。（２）羽根４２の後方がすぐに開放されているので、水の流れがより進み、発電効率がよい。(1) A large amount of water is collected by the first pipe 31 having a large diameter and the first collecting pipe 21 having a wide opening, and the blades 42 are rotated by the laminar flow 23, so that power can be generated efficiently. (2) Since the rear part of the blade 42 is immediately opened, the flow of water is further advanced and the power generation efficiency is good.

図６に水力発電装置１００の変形例の側面図を示す。第１管３１の長さＡは、第２管３２の長さＢより短い。第２管３２の径ｂは、第１管３１の径ａより小さいので、水が層流になるために時間を要するそのため、第２管３２の長さＢは、第１管３１の長さＡより長くする。
なお、第２管３２の径ｂに対する第１管３１の径ａの比率（ａ／ｂ）があり、第２管３２の長さＢは、第１管３１の長さＡと比率（ａ／ｂ）との積より長いのが好ましい。層流が確保できる。
なお、径は直径である。FIG. 6 shows a side view of a modified example of the hydroelectric power generation device 100. The length A of the first pipe 31 is shorter than the length B of the second pipe 32. Since the diameter b of the second pipe 32 is smaller than the diameter a of the first pipe 31, it takes time for water to form a laminar flow. Therefore, the length B of the second pipe 32 is the length of the first pipe 31. Make it longer than A.
There is a ratio (a / b) of the diameter a of the first pipe 31 to the diameter b of the second pipe 32, and the length B of the second pipe 32 is a ratio (a / b) to the length A of the first pipe 31. It is preferably longer than the product with b). Laminar flow can be secured.
The diameter is the diameter.

図７に水力発電装置１００の変形例の側面図を示す。中心線６０が、河底１１に平行である。水の流れは、河底１１に沿って流れる場合があり、その場所では、河底１１に平行になるように中心線６０をセットする。
＜全体として＞
上記では、第１管３１、第２管３２のみであったが、第３管、第４管など複数の管を繋いでもよい。管と収集管で１組であり、それを複数組連結できる。
収集菅、管、固定部の材質は金属を使用できるが表面に錆止めのコート膜を形成する必要がある。また、いくつかの部材をセラミックで作製してもよい。
上記例は、それぞれ組み合わせ出来る。FIG. 7 shows a side view of a modified example of the hydroelectric power generation device 100. The center line 60 is parallel to the riverbed 11. The flow of water may flow along the riverbed 11, where the centerline 60 is set so that it is parallel to the riverbed 11.
<As a whole>
In the above, only the first pipe 31 and the second pipe 32 were used, but a plurality of pipes such as the third pipe and the fourth pipe may be connected. There is one set of pipes and collection pipes, and multiple sets of them can be connected.
Metal can be used as the material for the collection tube, pipe, and fixing part, but it is necessary to form a rust preventive coating film on the surface. In addition, some members may be made of ceramic.
The above examples can be combined respectively.

図８に、水力発電装置１００を浮き体７０に配置した側面図を示す。浮き体７０はいかだ、船などで移動できる。川岸に浮き体７０を固定し発電できる。浮き体７０の上部に蓄電池７１を置き、ケーブル６５により電気を蓄えてもよい。無線給電で、陸地へ電力を飛ばしてもよい。
浮き体７０により、中心線６０を水面と平行に保て、効率的に発電できる。また、川の流れが速いところへ、移動できる。川の流れと水力発電装置１００の方向とを合わせることができる。FIG. 8 shows a side view in which the hydroelectric power generation device 100 is arranged on the floating body 70. The float 70 can be moved by a raft, a ship, or the like. The floating body 70 can be fixed on the riverbank to generate electricity. A storage battery 71 may be placed on the floating body 70, and electricity may be stored by the cable 65. Electric power may be sent to land by wireless power supply.
