It is about.

  Conventionally, as this type of power generation device, a device provided with power generation means using a Francis type water turbine is known. This Francis-type water turbine has a disk-shaped back plate with a rotating shaft penetrating therethrough, five blades protruding radially from the lower surface of the back plate, and a permanent magnet at a position above and away from the blades. Is fixed in the water channel, and is disposed in the water channel so that the water flow flowing through the water channel is orthogonal to the rotation axis from the outer circumferential direction of the water turbine.

Then, when a water flow occurs in the water channel, the water flow hits the blades and the water wheel rotates. The flow of magnetic flux from the permanent magnet changes as the permanent magnet also rotates with the rotation of the water turbine, and current flows through the stator coil in a direction that hinders the change, and power is generated (for example, see Patent Document 1). .

In the diaphragm plate 8 made of synthetic resin, a plurality of orifice holes 8a penetrating the water passage 6 and a main chamber 12 described later are formed in a penetrating state.

  The outlet 4 serving as a jet outlet is configured to increase the flow velocity of a water flow directed to a water turbine 31 provided on the downstream side, which will be described later, and to turn the water flow in the axial direction of the water turbine 31. Incidentally, in the present embodiment, a plurality of (for example, about 2 to 4) small holes (for example, about φ2 to 3 mm) are formed in the outer circumferential direction around the shaft hole 5, and these small holes are formed. It is formed to be inclined (for example, about 45 °).

The electromagnetic valve 27 is controlled by receiving an open / close signal from an electric control device (not shown).

  Next, the power generation means 30 which is a power generation device as a main part of the present invention will be described. The power generation means 30 according to the present embodiment includes a water wheel 31 that rotates by applying a water flow flowing through the water channel 6, a permanent magnet 34 fixed to the water wheel, and a stator coil 40 that generates an electromotive force by rotation of the permanent magnet 34. Are connected and fixed to the outflow port 4 of the body 2 by a fastening member (not shown).

  As shown in FIGS. 2A and 2B, the water wheel 31 is an axial-flow type water wheel 31 and is fixed to a polyacetal water wheel main body 32 with a stainless steel rotating shaft 33 penetrating therethrough. ing. A plurality of (for example, four) blade portions 32a for applying a water flow from the outlet 4 are provided radially outside the rotary shaft 33 in the water turbine main body 32. In the present embodiment, the above-described outlet 4 has an inclination angle (for example, about 30 to 45 °) corresponding to the inclination (for example, about 45 °). Thereby, the water flow from the outlet 4 is formed so as to easily apply the energy of the amount of water turning in the axial direction of the water wheel 31.

  Further, at one end of the water wheel 31, an outer cylindrical portion 32b and a protrusion 32c having a belt-like circumference are formed outside the blade portion 32a. A permanent magnet 34 having a substantially cylindrical shape is fixed so as to contact the end surfaces of the outer cylindrical portion 32b and the protruding portion 32c. Therefore, the water flow from the outlet 4 is configured to flow inside the outer cylindrical portion 32b and the permanent magnet 34. The permanent magnet 34 has N and S poles alternately magnetized in the circumferential direction of the water wheel 31.

  As shown in FIG. 1, the lower end of the rotating shaft 33 of the water wheel 31 is supported by a radial bearing 36 made of Teflon (registered trademark) resin fixed to a support member 35, and the upper end is formed of a body. It is pivoted on a shaft hole 5 formed in the shaft 2. A case 37 made of a stainless steel thin plate is provided so as to cover the water wheel 31, the permanent magnet 34, and the support member 35.

  Further, a yoke 38 made of a soft magnetic material is fixed to the body 2 by a fastening member (not shown) so as to be in contact with the case 37 on the outer peripheral side of the permanent magnet 34, and a coil bobbin 41 around which the stator coil 40 is wound is provided inside the yoke 38. Is installed. The stator coil 40 is connected to an external power storage unit (not shown) via a terminal (not shown).

  The body 2 and the case 37 are sealed by an O-ring 39. An outlet 35a formed in the support member 35 is connected to a downstream faucet (not shown). Thus, the water wheel 31 and the permanent magnet 34 are arranged at positions where water flowing in the water channel 6 directly hits. Therefore, at the time of water supply, by flowing the water flow flowing from the outlet 4 to the inner peripheral side of the permanent magnet 34, the water flow is applied to the blade portion 32a to rotate the water wheel 31 and the permanent magnet 34.

  A faucet (not shown) provided downstream of the outlet 35a has an infrared sensor (not shown) including a light-emitting element and a light-receiving element, which are detection means for detecting a human body (for example, a human hand) or an object. ) And an electric control device (not shown) as control means for controlling the opening and closing of the electromagnetic valve 27 based on a detection signal from the infrared sensor (not shown). Infrared sensors (not shown) detect the presence or absence of a human hand or the like in the vicinity, and the electric control unit controls opening and closing of the electromagnetic valve 27 to control water supply and water stop at the water discharge port. I have.

  Next, the operation of the water supply device in which the above-described power generation means 30 is provided at the outlet 4 will be described. As shown in FIG. 1, first, when the presence of a human hand is detected by an infrared sensor (not shown), the electromagnetic valve 27 is controlled by an electric control device (not shown). That is, in the solenoid valve 27, when the coil 20 is not energized in the closed state of the movable core 18, the magnetic flux from the annular magnet 23 causes the second ring 24, the movable core 18, the fixed core 19, the yoke 21, the first ring 22, It flows in the order of the annular magnet 23.

  Thus, a suction force acts between the movable core 18 and the fixed core 19. However, since the separation distance between the fixed core 19 and the movable core 18 is large, the attraction force of these cores is weak, the urging force of the spring 26 exceeds the magnetic attraction force, and the movable core 18 continues to close the valve.

  When a current is applied to the coil 20 in a direction in which a magnetic flux in the same direction as the above-described magnetic flux is generated in the closed state of the movable core 18 (this direction is defined as a positive direction), the magnetic attraction force of the annular magnet 23 increases, and The core 18 approaches the fixed core 19 by overcoming the urging force of the spring 26. Once the movable core 18 starts to approach the fixed core 19, the gap between the cores 18 and 19 becomes smaller, the magnetic flux attracting force further increases, and the movable core 18 is firmly attracted and held. The valve is opened.

  Even when the energization of the coil 20 is stopped when the movable core 18 is opened, the gap between the cores 18 and 19 is small, so that the biasing force of the spring 26 can be reduced only by the magnetic attraction by the magnetic flux of the annular magnet 23. Moving upward, the movable core 18 continues the valve-open state. When the coil 20 is energized so as to generate a magnetic flux in a direction opposite to the magnetic flux of the permanent magnet 34 from the valve-open state of the movable core 18 (this is defined as a reverse direction), the magnetic flux from the annular magnet 23 is applied to the fixed core 19. The movable core 18 separates from the fixed core 19 to be in a valve-closed state.

  As shown in FIG. 1, in a state where the movable core 18 is closed and the main valve 7 is seated on the valve seat 10, the water passage 6 upstream of the main valve 7 and the main chamber 12 communicate with each other through the orifice hole 8a. As a result, the water pressure in the upstream water passage 6 and the inside of the main chamber 12 become equal, and the force by the water pressure of the difference between the urging force of the spring 11 and the pressure receiving area acts, and the state where the main valve 7 is seated on the valve seat 10 is maintained. You.

  In this state, when a positive current is applied to the coil 20, the movable core 18 moves to open the opening of the passage 17, and the passage 15, the sub-chamber 16, the passage 17, and the outlet 4 communicate with each other, and Communicates with the upstream side of the water wheel 31. As a result, the water in the main chamber 12 flows out of the water turbine 31 through the passage 15, the sub-chamber 16, the passage 17, and the outlet 4, and the pressure in the main chamber 12 becomes lower than the pressure in the upstream water passage 6. The main valve 7 separates from the valve seat 10 due to the water pressure in the upstream water passage 6, and the water flows. In this water flowing state, when a current in the opposite direction is applied to the coil 20, the movable core 18 closes, water gradually flows into the main chamber 12 through the orifice hole 8a, and the main valve 7 gradually moves to the valve seat 10. When approaching, the water stops.

  Next, the operation of the power generation means 30 will be described. As shown in FIG. 1, when the main valve 7 is closed, the water is stopped, and the water wheel 31 and the permanent magnet 34 are in a stationary state. Then, when the main valve 7 is opened from this state, the water flow from the outlet 4 hits the blade 32 a of the water wheel 31, and the water wheel 31 rotates. In this manner, water is supplied at a rate of 5 to 15 L / min. At the same time, the permanent magnet 34 rotates with the rotation of the water wheel 31, and the flow of the magnetic flux transmitted from the permanent magnet 34 to the yoke 38 changes. Current flows through the stator coil 40 to generate electric power.

  Here, in the present embodiment, it has been described that the number of the outflow ports 4 which are the jet ports for increasing the flow velocity of the water flow is preferably two to four, but this will be described with reference to FIG. FIG. 3 is a characteristic diagram showing the relationship between the number of rotations of the water turbine 31 and the flow rate when the number of outlets 4 is changed to two to four, and the same hole diameter (for example, about φ2 mm) and the same blade It is a result of measuring the rotation speed of the water turbine 31 according to the flow rate in the portion 32a (for example, the number of blades is four). A shown in FIG. 3 indicates that the number of outlets 4 is 2, B is 3, and C is 4, and D indicates the relationship between the rotational speed and the flow rate in a conventional Francis type water turbine. .

  According to this, the three cases shown in B show substantially the same characteristics as the conventional product shown in D, and the pressure loss (not shown) also obtained the characteristics almost equivalent to the conventional product shown in D. Thereby, the number of the outlets 4 is preferably four, and more preferably two or three, whereby a power generation device having a high power generation capability even at a low flow rate can be obtained.

  According to the power generating means 30 of the first embodiment described above, in the conventional Francis-type water turbine, the water flow is applied to the blade portion 32a from the outer peripheral direction of the water turbine 31 so that the radial direction of the power generating means 30 is improved. Your physique grows. Moreover, the blade portion 32a is fixed below the rotating shaft 33 of the water turbine 31 and the permanent magnet 34 is fixed above the rotating shaft 33, so that the length of the water turbine 31 in the axial direction becomes longer. Physique also becomes large.

  Therefore, in the present invention, the blade portion 32a of the water wheel 31 is of an axial flow type capable of reducing the radial direction, and the blade portion 32a is configured to be rotated by the water flow flowing inside the permanent magnet 34, that is, the axial direction. Accordingly, the permanent magnet 34 is not separated from the blade 32a, so that the axial length can be shortened. Thereby, the radial direction and the axial direction of the water turbine 31 can be reduced, so that the size of the power generation means 30 can be reduced. In addition, since a plurality of blade portions 32a are formed outside the rotation shaft 33, the energy of the water flow flowing in the axial direction can be uniformly converted into rotation force, and highly efficient power generation can be obtained.

  Further, by providing a plurality of outlets 4 for increasing the flow velocity of the water flow applied to the blade 32a, it is possible to obtain highly efficient power generation even with a low flow water flow. Further, by inclining the outlet 4, the water flow hitting the blade 32a can be swirled. By applying the swirled water flow to the blade 32a, it is possible to obtain highly efficient power generation even with a low flow water flow.

(2nd Embodiment)
In the above-described first embodiment, the permanent magnet 34 and the water wheel 31 having the blade 32a are fixed so that the blade 32a is housed inside the permanent magnet 34.
