Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hydroelectric generator for a faucet, for example, to an automatic faucet hydroelectric generator that stores electric power generated by turning a hydroelectric generator with running water and operates with the electric power. .
[0002]
[Prior art]
[Patent Document 1]
In recent years, a so-called automatic faucet that discharges water by simply extending a hand without touching the faucet has been widely used. This automatic faucet needs electric power to detect that an object to be detected such as a human body is located in the vicinity of the water outlet, and also needs electric power to operate the electromagnetic valve to discharge water. . In addition, there is an automatic faucet equipped with a small hydroelectric generator that rotates a water turbine by rotating the water wheel with the momentum of water discharged to obtain this electric power.
[0003]
In the configuration of the hydroelectric generator disclosed in Patent Document 1, a rotor made of a hydroelectric turbine and a generator's polarized magnet is placed in water. The stator is composed of an iron core magnetic circuit and a coil, and is placed in the atmosphere. Therefore, the partition wall of water and air is located in the magnetic field between the rotor and the stator, and this partition wall is provided with a nonmagnetic metal.
[0004]
The reason for this structure is that if a rotating shaft is provided so as to penetrate the partition and the bearing portion is made watertight, the mechanical loss is large, and a small amount of running water provides the necessary rotation for power generation. It is because it is not possible.
[0005]
[Problems to be solved by the invention]
However, in the configuration shown in Patent Document 1, not only water with low permeability is interposed in the magnetic field between the rotor and the stator, but also a nonmagnetic metal having a thickness enough to withstand water pressure. Even if the rotor rotates, a sufficient magnetic force cannot be transmitted to the stator, and it is inevitable to reduce the power generation efficiency of the generator. Therefore, it is possible to improve the electromotive force by increasing the magnetic force of the rotor, but it is inevitable that the stronger the magnetic force of the rotor, the greater the torque required at the start of the generator. When water was flowed at a small flow rate, there was a problem that the water wheel did not rotate.
[0006]
The present invention has been made in consideration of the above-mentioned matters, and its purpose is a faucet having a power generation unit capable of efficiently converting rotational force into electric power without being affected by absorption of magnetic force by water. It is to provide a hydraulic power generator.
[0007]

In order to achieve the above object, a hydroelectric generator for faucets of the present invention includes a water turbine configured to rotate by a flow of water controlled by the faucet,
A rotating magnetic body connected to the water wheel;
A storage chamber for storing the water wheel and the rotating magnetic body in communication with the water pipe;
A partition that maintains the watertight state of the water in the storage chamber and transmits the magnetic force of the rotating magnetic body to the outside isolated from the water;
A driven rotating magnetic body that receives a rotating force from the water wheel by receiving a rotating magnetic field generated by rotation of the rotating magnetic body outside the partition;
A power generation unit that converts the rotational force transmitted by the driven rotating magnetic body into electric power;
A first shaft disposed in water and continuously connecting the water wheel and the rotating magnetic body;
A second rotating shaft disposed on the same axis as the first shaft, the driven rotating magnetic body and the power generation unit being arranged continuously in the atmosphere;

Further, the water wheel housed in the water wheel housing portion is located immediately downstream thereof, and has an inner diameter formed narrower than the inner diameter of the water pipe in a state along a direction orthogonal to the direction of the shaft core. The water turbine housing block is drilled so as to convert the water flow in the water pipe into a squeezed water flow along a direction orthogonal to the direction of the shaft core, and the squeezed water flow the water wheel have a communicating hole which can rotate, said receiving chamber is composed of said water wheel housing portion, a rotating magnetic storage portion for storing the rotating magnetic member by,

[0008]
[0009]
That is, in the hydroelectric generator for faucets of the present invention, the water wheel is disposed in the water and the power generation unit is disposed in the atmosphere. Therefore, the water wheel is efficiently rotated by the flow of water, and the power generation unit has less magnetic flux leakage. Rotational force can be efficiently converted into electric power.
[0010]
In addition, since the shafts of the water turbine and the power generation unit are connected via a water and air barrier using an attractive force or a repulsive force by a magnetic force, an appropriate damper can be formed between the water wheel and the power generation unit. Furthermore, since the power generation unit converts the rotational force into electric power while being isolated from the water, there is no limitation on the shape thereof, and the power conversion efficiency can be prioritized. In addition, an efficient power generation unit requires a relatively strong rotational force, but since a moderate damper is formed between the turbine and the power generation unit, the required torque at the time of starting the turbine can be reduced. A relatively large electric power can be generated using a small amount of water.
[0011]
[0012]
Further, the first shaft arranged in the water and connected to the water wheel and the rotating magnetic body, and the driven rotating magnetic material and the power generation unit arranged in the atmosphere and connected to the first shaft are on the same axis. A power generation unit formed on the second shaft, the second shaft being rotated by following the rotation of the first shaft by the attractive force of the rotating magnetic body and the driven rotating magnetic body. Any shape can be designed.
[0013]
The shape of the rotating magnetic body and the driven rotating magnetic body is a disk-shaped magnet connected to the shaft ends of the first shaft and the second shaft, so that a sufficient rotational force can be transmitted and the configuration can be made as simple as possible. it can.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a view showing a configuration of an embodiment of a hydroelectric generator 1 for a faucet of the present invention.
In FIG. 1, 2 is a water pipe bent in a generally L shape that communicates with a water faucet (not shown), and 3 is positioned at a bent portion of the water pipe 2 and rotated by the flow of water flowing in the water pipe 2. A water wheel 4 configured to be configured has a first shaft that rotatably supports the water wheel 3, and 5 is a rotating magnetic body that is connected to the shaft end of the first shaft 4 to be connected to the water wheel 3. 6 is a storage chamber for storing these members 3 to 5 in communication with the water pipe 2, and 7 is an external space in which the water in the storage chamber 6 is kept watertight and the magnetic force of the rotating magnetic body 5 is isolated from water. A partition wall made of a nonmagnetic metal that is transmitted through the rotating magnetic body 5 is a driven rotating magnetic body that receives a rotating magnetic field generated by the rotation of the rotating magnetic body 5 on the outside of the partition wall 7 and receives a rotational force from the water turbine 3, and 9 is a driven rotating This is a second shaft that connects the magnetic body 8 to one end, and is disposed on the same axis as the first shaft 4. Reference numeral 10 denotes a power generation unit connected to the other end of the second shaft 9.
[0015]
The water pipe 2 of this example has connection parts 2a and 2b at its ends, and can be attached so as to be interposed in the flow path of the water pipe that communicates with a valve element that is opened and closed by a water tap outside the figure. Yes. In addition, the hydraulic power generator 1 for a faucet of the present invention is not limited to the configuration interposed in the flow path of the water pipe 2, but may be configured to be incorporated in the faucet.
[0016]
Further, the rotating magnetic body 5 and the driven rotating magnetic body 8 use an attractive force or a repulsive force between the water wheel 3 and the power generation unit 10 (the rotating magnetic field formed by the rotating magnetic body 5 is driven by the rotating magnetic field). By receiving the body 8), it functions as a rotational force transmission mechanism 11 for transmitting rotational force to the power generation unit 10 isolated from the underwater water turbine 3 with respect to the water.
[0017]
The storage chamber 6 of this example is configured by being divided into, for example, a water wheel storage portion 6 a that stores the water wheel 3 and a rotating magnetic material storage portion 6 b that stores the rotating magnetic material 5. And in order to make the frictional resistance accompanying rotation in the bearing part 4a of the 1st axis | shaft 4 as small as possible, it is comprised so that some water may pass between both the accommodating parts 6a and 6b by providing some clearance gaps. Yes.
[0018]
The turbine housing portion 6a is formed by a turbine housing block 12 that is detachably connected to the water pipe 2. The turbine housing block 12 includes a water turbine housing block body 12a that forms the bearing portion 4a, and a first wheel housing block body 12a. It consists of a water wheel pressing block 12b having a bearing 4b of the shaft 4. On the other hand, the rotating magnetic body accommodating portion 6b is formed by pressure-bonding the partition wall 7 to the water turbine accommodating block main body 12a. H is a communication hole. And the said water turbine 3 accommodated in the said water turbine accommodating part 6a is located just downstream of the communicating hole h of an arc. The communication hole h is formed in the water turbine housing block main body 12a of the water turbine housing block 12 so as to have an inner diameter formed narrower than the inner diameter of the water pipe 2 in a state perpendicular to the direction of the shaft core. It converts the flow of water in the water pipe 2 into a flow of squeezed water along a direction orthogonal to the direction of the axis, and rotates the water turbine 3 by the squeezed water flow. It can be made.
[0019]
Reference numeral 13 denotes a rotational force transmission block that houses the rotational force transmission mechanism 11 and has a bearing portion 9a of the second shaft 9 made of a bearing or the like, and presses the partition wall 7 against the water turbine housing block main body 12a.
[0020]
The power generation unit 10 includes, for example, a cover body 14 connected to the rotational force transmission block 13, a bearing portion 9b of the second shaft 9, a rotor 15 that rotates in conjunction with the rotation of the second shaft 9, and a rotor. And a stator 16 such as an electromagnetic coil that obtains an electromotive force by rotation of 15.
[0021]
The faucet hydroelectric generator 1 generates a rotational force in the water turbine 3 when water flows through the water pipe 2. This rotational force is transmitted to the rotating magnetic body 5 through the first shaft 4, and the rotating magnetic body 5 rotates. As the rotating magnetic body 5 rotates, a rotating magnetic field is generated outside the partition wall 7, and the rotating force is transmitted from the rotating magnetic body 5 to the driven rotating magnetic body 8 using the attractive force and repulsive force of the magnetic force. The
[0022]
The rotational force transmitted to the driven rotating magnetic body 8 is transmitted to the rotor 15 of the power generation unit 10 via the second shaft 9 and is converted into electric power by generating an electromotive force in the stator 16. In the case of the present example, the power generation unit 10 that converts the rotational force output to the second shaft 9 into electric power is formed in a portion that is completely isolated from water, so that the structure can be designed freely. That is, the power generation unit 10 can be any one that can generate the required power. Therefore, it goes without saying that the configuration of the power generation unit 10 shown in this example is an example of a typical power generator, and does not limit the present invention.
[0023]
As shown in this example, there is no partition wall 7 or the like in the gap between the rotor 15 and the stator 16, so that the leakage magnetic flux can be remarkably reduced by narrowing the gap. That is, the power generation efficiency in the power generation unit 10 can be increased. Moreover, the power generation efficiency can be increased as much as possible by using an existing power generator formed by using various techniques already established in the power generation unit 10.
