Description

    The present invention relates to a power generation device and a hydroelectric power generation device, and more particularly to a small hydroelectric power generation device disposed in a river or a water channel.

    JP, 2013-2535577, A is known as a small hydroelectric generator (micro pico hydroelectric generator) which generates electricity using the flow of a river or a canal. A runner rotor is provided immediately after the inlet of the power generation channel inside the duct, and a transmission means is linked between the generator provided outside and the rotor shaft. The flowing water that hits the blades of the rotor flows out along the inner wall surface of the power generation channel.

    In the conventional micro hydroelectric generator described above, the fixing device and the power generation part of the main body are separated, the installation place is limited, and the movement is not easy. Further, since the runner and the generator are connected by the shaft, the shaft seal of the power generation portion is necessary, and deterioration of the shaft seal portion leads to failure. Furthermore, it is difficult to use at low water levels.

It is sectional drawing of the small hydroelectric generator cut | disconnected along the II-II line | wire of FIG. It is sectional drawing of the small hydraulic power unit which shows the other Example of this invention.

    A completely sealed waterproof small hydroelectric generator A according to an embodiment of the present invention will be described. FIG. 1 is a cross-sectional view of a small hydroelectric generator A showing an embodiment of the present invention. The small hydroelectric generator A is mainly composed of a hydraulic unit 10 in which a fluid flows and a power generation unit 50 arranged to face the hydraulic unit 10. The small hydroelectric generator A is installed by being submerged and buried in running water such as a river or waterway.

    The hydropower unit 10 and the power generation unit 50 are separated and partitioned by a nonmagnetic partition wall 30. The running water inside the hydraulic unit 10 does not flow out to the power generation unit 50 due to the arrangement of the partition walls 30. The partition wall 30 prevents the flowing water of the hydraulic unit 10 from flowing into the power generation unit 50, and blocks the flowing water from the hydraulic unit 10 to the power generation unit 50 by the partition wall 30. The hydraulic unit 10 and the power generation unit 50 are arranged via a packing 40, and the small hydroelectric generator A is waterproofed by the packing 40.

    The runner unit 10 that is the hydraulic unit 10 has a runner case 11, and the runner case 11 has an inlet 12 and an outlet 13 for running water. As shown in FIG. 2, a runner 15 having a blade 14 is provided in the runner case 11 in the axial direction of the runner 15. A chamber 16 is formed between the blades 14 of the runner 15.

    A cylindrical runner magnet storage portion 17 is provided on the inner periphery of the runner 15. A runner magnet 18 facing the base of the blade 14 is housed and arranged concentrically inside the runner magnet housing portion 17. A bearing 20 is provided below the runner shaft 19 of the runner 15, and is disposed in the center of the runner case 11.

    The partition wall 30 includes a partition wall outer ring 31 and a cylindrical bottomed recess 32 extending downward at the center connected to the outer ring 31. The recessed portion 32 integrally includes a cylindrical vertical portion 33 and a planar bottom portion 34 connected to the vertical portion 33. The partition wall 30 prohibits movement of running water from the hydraulic unit 10 to the power generation unit 50 and blocks water.

    The power generation unit 50 is mainly configured by a connector 60 and a generator 52 housed in a generator case 51 located above the connector 60.

    As shown in FIGS. 1 and 2, the connector 60 mainly includes a rotating body shaft 61 and a cylindrical rotating body 62 connected to the rotating body shaft 61. The entire rotating body 62 is housed inside the recess 32 of the partition wall 30. As shown in FIG. 2, generator magnets 64 are concentrically housed in a cylindrical generator magnet housing portion 63 provided on the outer periphery of the rotating body 62.

    The runner magnet 18 and the generator magnet 64 are disposed to face each other with the vertical portion 33 of the partition wall 30 interposed therebetween. The runner magnet 18 is provided around the vertical portion 33 of the partition wall 30 so as to be opposed to the generator magnet 64 at a certain interval. The runner magnet 18 and the generator magnet 64 are arranged in a non-contact state. The runner magnet 18 and the generator magnet 64 are provided to face the vertical portion 33 of the recessed portion 32.

    The runner magnet 18 and the generator magnet 64 attract each other with an attractive force. The rotating body 62 rotates with an attraction between the magnetic force of the runner magnet 18 and the magnetic force of the generator magnet 64 while having an equally-spaced gap.

    The runner 15 and the rotating body 62 are interlocked by the runner magnet 18 and the generator magnet 64, and the runner magnet 18 and the generator magnet 64 form a magnetic coupling structure. By adopting this magnetic coupling structure, a shaft for connecting the runner 15 and the rotating body 62 becomes unnecessary, and water leakage due to packing damage can be prevented.

    The power generation unit 50 mainly includes a generator case 51, a generator mounting plate 52, a permanent magnet generator 53 mounted on the generator mounting plate 52, and a generator shaft 54 of the generator 53. . The permanent magnet generator 53 has a known structure of a permanent magnet structure and a fixed coil structure. The electric power obtained from the generator 53 can be transmitted to an external emergency street light or the like.

    In the hydroelectric generator A of the present invention, a speed increasing mechanism 70 is disposed between the generator shaft 54 and the rotating shaft 61 of the connector 60. The speed increasing mechanism 70 includes four gears 71, a gear 72, a gear 73, and a gear 74. The speed increasing mechanism 70 is arranged by combining a gear or the like between the runner 15 and the power generator 53 in consideration of the case where the speed of the runner 15 does not reach the required speed of the power generator 53.

    The flowing water flows in from the inlet 12 of the runner case 11, fills the chamber 16, hits the blade 14, pushes the blade 14, and rotates the runner 15. The runner 15 is continuously rotated with the pressure energy and momentum of the flowing water, and converted into the rotation energy of the runner 15. The partition wall 30 prohibits movement of the flowing water of the hydraulic unit 10 to the power generation unit 50 and blocks water.

    When the runner magnet 16 rotates, the rotating body 62 having the generator magnet 64 also rotates in the same direction as the runner 15 together. The runner magnet 18 and the generator magnet 64 are attracted by the attractive force and rotated in the same direction in a non-contact state.

    The rotation of the rotating body 62 is transmitted to the generator shaft 54 via the speed increasing mechanism 70. The generator 53 is rotated by the rotation of the generator shaft 54 to generate power.
