In the present embodiment, the locking portion 57 of the water flow guide member 5 is formed to have the same size and shape as the locking portion 46 of the hydroelectric generator 4.

  When the force received from the flow of the water channel 2 is stronger than the force applied from the spring 51a (pressing part 51), the water flow guide member 5 of the present embodiment described above, as shown in FIG. 50 opens the opening 55 to be in an open state. By opening the door body 50 in this manner, the water flow guide member 5 can release the flow of the water channel 2 to the downstream side of the door body 50 through the opening 55. When the force received from the flow of the water channel 2 is weaker than the force applied from the spring 51a (pressing portion 51), the door body 50 closes the opening 55 and closes as shown in FIG. It becomes. By closing the door body 50 in this manner, the water flow guide member 5 can receive the flow of the water channel 2 and guide it to the hydroelectric generator 4.

  4A and 4B show the first support member 30 of the present embodiment. The second support member 31 of the present embodiment has a structure in which the first support member 30 shown in FIGS. 4A and 4B is reversed left and right. The first and second support members 30 and 31 have a long column shape. The first and second support members 30 and 31 include a frame 32 having a substantially U-shaped cross section, a plurality of (two in the present embodiment) support bars 33 installed at the opening tip of the frame 32, and A plurality of (two in this embodiment) locking means 34 attached above each support bar 33. The plurality of support bars 33 are spaced apart from each other in the vertical direction. Each locking means 34 is attached to the inside of the downstream portion of the frame 32. The locking portion 57 of the water flow guide member 5 or the locking portion 46 of the hydroelectric generator 4 is inserted into the inner space of the frame body 32 above each support bar 33, moved downward, and hooked on each support bar 33. The lock member 34 is supported by the support member 3 by fixing its locked state.

  The frame body 32 is configured by a rectangular plate-like rear wall 32a and rectangular plate-like both side walls 32b and 32c protruding perpendicularly from both end portions thereof in a substantially U-shaped cross section. The first and second support members 30 and 31 are attached so that the back surface of the rear wall 32a faces the water channel 2 side of the dikes 20a and 21b. Hereinafter, the side wall 32b positioned on the downstream side with the rear surface of the rear wall 32a facing the water channel 2 side of the dikes 20a and 21b is referred to as the downstream side wall 32b, and the side wall 32c positioned on the upstream side is the upstream side. It is called side wall 32c.

  A plurality of rod-like (two in this embodiment) support bars 33 are installed at the distal ends of the upstream side wall 32c and the downstream side wall 32b so as to be spaced apart in the vertical direction. A rectangular plate-shaped locking means 34 is fixed inside the downstream side wall 32b above each support bar 33 at a predetermined distance from each support bar 33 in the vertical direction and the front-rear direction.

  The locking means 34 is provided with the locking portions 46 and 57 between the support bars 33, so that the protruding portions below the tips of the locking portions 46 and 57 are locked to the support bars 33. It prevents that it remove | deviates from the support member 3 from a state. The engaging portions 46 and 57 are arranged in the water channel 2 to receive a water pressure and apply a force downstream. As a result, the locking portions 46 and 57 are unlikely to be removed upstream from the vertical gap between the support bar 33 and the lock means 34.

  As shown in FIG. 4B, the locking means 34 is formed in a tapered shape so that the distance between the upper end portion and the upstream side wall 32c increases toward the upper side. Thus, it is easy to install the locking portions 46 and 57 inserted into the inner space of the frame 32 of the locking means 34 on the support bar 33.

  An example of the installation procedure of the hydroelectric power generation facility 1 of the present embodiment described above on the river 2a will be described.

  First, from the upper side of the bank 20a which is one end portion 20 in the width direction of the river 2a, a hole or the like is dug in the river bed (bottom 22) at a position close to the bank 20a, and a columnar support member 3 ( The lower end of the first support member 30) is driven. Thereby, the position of the lower end of the support member 3 (first support member 30) is fixed. It is not always necessary to drive the lower end of the support member 3 (first support member 30) into the river bed (bottom 22), and the lower end of the support member 3 (first support member 30) is fixed by other means. Also good.

  Next, the substantially L-shaped fixture 6 is locked to the upper end portion of the rear wall 32a of the first support member 30, and the upper end portion of the first support member 30 is fixed to the bank 20a. A plurality (four in the present embodiment) of first support members 30 are fixed to the one bank 20a with a predetermined interval along the flow direction of the river 2a. Here, the 1st support member 30 is arrange | positioned so that the back surface of the rear wall 32a of the frame 32 may overlap with the water channel 2 side of the bank 20a. Similarly, one support member 3 (second support member 31) is fixed to the dike 21b which is the other end portion 21 in the width direction of the river 2a. At this time, the second support member 31 is fixed so that the opening direction of the frame body 32 faces the direction in which the connecting portion 47 of the hydroelectric generator 4 supported by the first support member 30 is positioned thereafter. In the present embodiment, the second support member 31 is disposed at substantially the same position as the first support member 30 disposed in the uppermost stream and the flow direction of the river 2a.

  Next, the hydroelectric generator 4 is lifted with a crane or the like and installed in the river 2a. At this time, the six locking portions 46 of the hydroelectric generator 4 are inserted into the frame bodies 32 of the second to fourth first support members 30 counted from the upstream side and locked to the support bars 33. . The hydroelectric generator 4 is forced downstream by the flow of the river 2a, so that the six locking portions 46 enter between the support bars 33 and the locking means 34 and the locked state is fixed. . Thereby, the hydroelectric generator 4 is supported by the 1st support member 30, and the position in the river 2a is fixed. In this embodiment, the hydroelectric generator 4 is fixedly installed so that the opening direction of the cylindrical housing 40 is the same as the flow direction of the river 2a.

  Next, the water flow guide member 5 is lifted by a crane or the like and installed in the river 2a. At this time, while the water flow guide member 5 is submerged in the river 2a so that the longitudinal direction thereof is parallel to the flow direction of the river 2a, the two connected portions 58 at the downstream end of the water flow guide member 5 are 4 is inserted into the two hole-like connecting portions 47.

  Next, the upstream end portion of the water flow guide member 5 is gradually brought closer to the bank 21 b, and the two locking portions 57 of the water flow guide member 5 are locked to the support bars 33 of the second support member 31. The water flow guide member 5 is forced downstream by the flow of the river 2a, so that the two locking portions 57 enter between the support bar 33 and the locking means 34 and the locked state is fixed. Thereby, the water flow guide member 5 is supported by the 2nd support member 31, and the position in the river 2a is fixed. In the present embodiment, the water flow guide member 5 is arranged on the upstream side of the hydroelectric power generation device 4 and concentrates the flow of the river 2 a on the hydroelectric power generation device 4, so that the downstream side is closer to the hydroelectric power generation device 4. 2a is inclined with respect to the flow. The connection of the water flow guide member 5 to the hydroelectric generator 4 and the connection to the second support member 31 may be performed simultaneously.

  Next, the most upstream first support member 30 and the downstream end of the water flow guide member 5 are connected by a connecting tool 7 such as a rope or a wire. At this time, the connector 7 is tied to the upper frame 52 above the opening 55 on the most downstream side of the water flow guide member 5. Thereby, the support strength of the downstream end part of the water flow guide member 5 can be strengthened. In addition, you may connect the connection part 47 of the hydroelectric generator 4 and the 1st support member 30 of the uppermost stream with the connection tool 7 instead of the water flow guide member 5. FIG. Even if it does in this way, the support strength of the downstream edge part of the water flow guide member 5 can be strengthened via the connection part 47. FIG.

  Then, the first support member 30 at the most downstream side and the portion on the downstream side of the hydroelectric generator 4 on the water flow guide member 5 side are connected by the connector 7.

  In the hydroelectric power generation facility 1 of the present embodiment arranged in the river 2a as described above, the water flow guide member 5 is arranged on the upstream side of the hydroelectric generator 4 as shown in FIG. A water flow guide member 5 is connected to the hydroelectric generator 4. Thereby, the flow of water flowing through the river 2 a is received by the water flow guide member 5, and this flow is concentrated on the hydroelectric generator 4, and the power generation efficiency of the hydroelectric generator 4 can be improved.

  In addition, in the hydroelectric power generation facility 1 of the present embodiment, as shown in FIG. 1B, the water flow guide member 5 and the hydroelectric generator 4 are separated from the river bed (bottom 22) of the river 2 a by the support member 3. By being opened and supported, a lower space can be formed between the water flow guide member 5 and the hydroelectric generator 4 and the bottom 22 of the water channel 2. Thereby, the earth and sand flowing through the river bed (bottom 22) of the river 2a flows downstream through this lower space. As a result, it is possible to prevent the earth and sand from flowing into the hydroelectric generator 4 to reduce the rotational efficiency of the hydraulic turbine 41 of the hydroelectric generator 4 and the hydraulic turbine 41 of the hydroelectric generator 4 from being damaged.

  Further, in the hydroelectric power generation facility 1 of the present embodiment, as shown in FIG. 1B, the water flow guide member 5 and the hydroelectric power generation device 4 supported by the support member 3 are disposed below the water surface of the river 2a. The Thereby, floating foreign matters such as dead leaves, trees, and dust flowing near the water surface of the river 2a flow downstream of the water flow guide member 5 and the hydroelectric generator 4 as they are. As a result, it is possible to prevent these floating foreign substances from flowing into the hydroelectric generator 4 to reduce the rotation efficiency of the water turbine 41 of the hydroelectric generator 4 and to damage the hydraulic turbine 41 of the hydroelectric generator 4.

  As described above, in the hydroelectric power generation facility 1 of the present embodiment, since the inflow of earth and sand or floating foreign matter into the hydroelectric power generation device 4 can be suppressed, the necessity for maintenance is low and the device is easy to use. Moreover, the hydroelectric power generation equipment 1 of this embodiment becomes difficult to impair a natural scenery by arrange | positioning the water flow guide member 5 and the hydroelectric generator 4 below the water surface of the river 2a.

  Moreover, in the hydroelectric generator 1 of this embodiment, as shown in FIG. 3, the water flow guide member 5 includes a plurality of openings 55 that open in the flow direction of the water channel 2, and a plurality of door bodies 50 that open and close the openings. And a plurality of pressing portions 51 that press the door body 50 to the upstream side with a predetermined force. As a result, when the momentum of water such as when water increases, the door body 50 automatically opens, reducing the force received from the flow of the water channel 2, and the water flow guide member 5 or a support member for supporting the same. 3 can be prevented from being damaged. Moreover, by providing the door body 50 with two or more, the force received from the flow of the water channel 2 can be disperse | distributed, and it can also suppress that the door body 50 itself is damaged. Further, when the momentum of the water becomes less than a predetermined value, the door body 50 can be automatically closed by the pressing portion 51, and the water flow guide member 5 is guided to the hydroelectric generator 4 by receiving the flow of the water channel 2. It can return to the state to do.

  In the above-described water flow guide member 5, the example in which the same number of openings 55 and door bodies 50 are arranged side by side over substantially the entire length of the water flow guide member 5 has been described. The door body 50 may not be provided in the opening 55 at the end on the side away from the hydroelectric generator 4 according to the amount of water to be applied and the load applied to the water flow guide member 5.

  Further, in the above-described embodiment, the door body 50 is provided so as to be pressed upstream by the pressing portion 51 with respect to the opening 55 of the water flow guide member 5, and the automatic operation is performed in response to the momentum of the water flowing through the water channel 2. Although the door body 50 is configured to open and close the opening 55, the present invention is not limited to this. That is, you may comprise so that the door body 50 may open and close the opening part 55 by operation from the outside.

  Further, the water flow guide member 5 is not limited to the configuration of the above-described embodiment as long as it can release the force when receiving a force of a predetermined level or more from the flow of the water channel 2. For example, when the water flow guide member 5 is formed of an elastically deformable rectangular plate and the strength received from the flow of the water channel 2 is greater than or equal to a predetermined value, one end in the short direction is elastically displaced downstream. It may be a thing.

  In addition, the first support member 30 on the most upstream side and the most downstream side described above only need to be able to tie the connection tool 7, and are different from the second to fourth first support members 30 counted from the upstream side. It may be a structure. In addition, the configuration of the first support member 30 at the most upstream and the most downstream is omitted, and the hydroelectric generator 4 and the water flow only by the second to fourth first support members 30 and the second support member 31 counted from the upstream side. The guide member 5 may be supported.

  The support member 3 is not limited to the shape described above. For example, the support member 3 may include three or more support bars 33 that are spaced apart in the vertical direction. By doing in this way, when making the support member 3 support the hydroelectric generator 4 and the water flow guide member 5, height setting can be made easy.

  Further, as shown in FIG. 5, the support member 3 (first support member 30) may be formed in a block shape and support one locking portion 46.

  Specifically, the support member 3 shown in FIG. 5 fixes the frame 35 opened upward, the support bar 36 disposed in the frame 35, and the locking portions 46 and 57 locked to the support bar 36. Locking means 37. The frame body 35 includes a lower wall 35a and both side walls 35b and 35c protruding upward from both ends thereof. One end portion in the longitudinal direction of the rod-shaped locking means 37 is rotatably attached to the upper end portion of the side wall 35c disposed on the upstream side. Further, a groove 38 into which the other end portion in the longitudinal direction of the locking means 37 is fitted is formed in the side wall 35b arranged on the downstream side at a location corresponding to the locking means 37. The locking means 37 is arranged such that the support member 3 is disposed in the water channel 2, and a force is applied to the locking device 37 downstream by the flow of the water channel 2, so that one end in the longitudinal direction can be easily held in the groove 38. It has become. The second support member 31 has a structure in which the first support member 30 is reversed left and right.

  Moreover, although it is preferable to provide one hydroelectric generator 4 and one water flow guide member 5 in the water channel 2, the number of the hydroelectric power generator 4 and the water flow guide member 5 is changed according to the width of the water channel 2. It doesn't matter. For example, the water flow guide member 5 is supported by the second support member 31, and the hydroelectric generator 4 is supported by the first support member 30 via the other water flow guide member 5, and the hydroelectric generator is formed by the two water flow guide members 5. The upper and lower positions of 4 may be fixed. Even in this case, the hydroelectric generator 4 and the water flow guide member 5 are disposed so as to be spaced apart from the bottom 22 of the water channel 2 in water, thereby suppressing the inflow of earth and sand into the hydroelectric generator 4 and natural It is possible to avoid damaging the scenery as much as possible.

  The hydroelectric generator 4 and the water flow guide member 5 are preferably connected to each other, but the hydroelectric power generator 4 and the water flow guide member 5 may be provided separately. In that case, the water flow guide member 5 may be arranged so that the flow received by the water flow guide member 5 can be concentrated on the hydroelectric generator 4.

  Although the present invention has been described based on the embodiments shown in the accompanying drawings, the present invention is not limited to the above-described embodiments, and appropriate design changes can be made within the intended scope of the present invention. It is.
