Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water receiving plate for a water generator capable of converting movement of flowing water into rotation of a drive shaft in a constant direction regardless of the movement direction.

[0002]

[Prior Art]

 Conventionally, various ideas have been made to extract the energy of running water and drive a generator.

[0003] Examples thereof include the conventional type submersible turbine of FIG. 7 and the tide wheel of FIG.

These devices are of a type in which the rotating part W is rotated by the energy of moving water and the generator S is driven by the rotation of its shaft S.

[0005]

[Problems to be solved by the device]

 In the so-called conventional turbine power generation, it is required that the direction of running water is constant, and if the direction of running water is reciprocating, for example, the energy of running water in one direction should be discarded, or Alternatively, it was necessary to prepare a special gear device to capture the reciprocating flowing water energy.

However, in order to extract the energy of the reciprocating running water with a single rotating shaft, it is necessary to use a complicated structure, and the structure is bulky for application to a simple running water power generator. However, it has become unprofitable in terms of price, and for that reason, effective devices have not been supplied until today.

[0007]

[Means for Solving the Problems]

 The present invention has been devised so that the rotating shaft for driving the generator will always rotate in a fixed direction when the flowing water moves only in a fixed direction but also in the reciprocating direction. It relates to a water receiving plate for a generator.

Although the structure of the water receiving plate is arbitrary, a support portion is radially planted on the drive shaft of the generator, and the water receiving portion is swingably and pivotally attached to the support portion. In addition, a stop portion that limits the swing range of the water receiving portion is attached to the support portion.

Although the number of supports to be planted on the drive shaft is arbitrary, at least three supports are installed in order to accurately capture the movement of running water and reduce the cost of the device. Is desirable.

Therefore, one drive shaft has three sets of water receiving plates.

[0011] The swinging range of the water receiving portion is such a range that the energy of the flowing water can be reliably received for the flowing water from one direction and the energy of the flowing water in the opposite direction can be almost passed. It is not necessary to set the swing angle in particular.

[0012] Generally, in the state where the water receiving portion hangs downward from the supporting portion, the energy of the flowing water from one direction applied to the water receiving portion is transmitted to the supporting portion and is added to the water receiving portion from the opposite direction. It is desirable that the stored energy be discharged with almost no trapping.

If three such water receiving portions are installed on one drive shaft and the mutual opening angles are set to 120 degrees apart, the drive shaft is always fixed regardless of the moving direction of the flowing water. It becomes possible to rotate in the direction.

【Example】

 FIG. 1 is a schematic view of a simple flowing water generator having a water receiving portion according to the present invention, where 1 is a drive shaft for driving a generator D1 or D2, and 2 is a drive shaft. 1 a lathe wheel fixed to the lower end, 3 a support part planted in a lathe wheel, 4 a water receiving part pivotally attached to the support part 3 by a hinge 5, 6 a hinge 5 to a water receiving part 4 It is a stop that extends along one side.

The mutual positional relationship among the support portion 3, the water receiving portion 4, the hinge 5, and the stopper portion 6 is as shown in the enlarged perspective view of FIG.

Reference numeral 7 is a frame for indicating the drive shaft 1, and the above-mentioned generator D1 or D2 is installed and fixed on the frame 7.

In the example shown in FIG. 1, the generator D1 is in contact with the rotary flange 8 fixed to the end of the drive shaft 1, and is the type in which the first product is driven by the rotation of the rotary flange 8. ..

Similarly, the generator D 2 is driven by transmitting the rotation of a rotary wheel (or rotary gear) 9 fixed to the drive shaft 1 via a belt (or chain) 10.

The electric power generated by these generators is used to emit the light source 11 installed in the frame body 7.

The electric power generated by the generator can also charge the storage battery via a simple rectifier circuit, but its configuration is not shown in order to simplify the drawing.

In FIG. 1, when the water receiving part 4 transmits the energy of flowing water to the drive shaft 1 and rotates the drive shaft in a certain direction, the generator D1 or D2 is driven to generate electric power. Will be done.

Next, referring to FIGS. 3 and 4, how the water receiving portion 4 operates in accordance with the direction of flowing water will be described.

As shown in FIG. 3, when the running water presses the water receiving portion 4 and causes the water receiving portion 4 to press the stop portion 6 of the support portion 3, the support portion 3 moves the planted drive shaft 1 It will be rotated.

When the moving direction of the flowing water is opposite to that shown in FIG. 3, the water receiving portion 4 swings away from the stop portion 6, as shown in FIG. Also, it hardly affects the drive shaft 1.

In these explanations, the water receiving portion 4 faces the same direction regardless of the moving direction of the flowing water, so that the water receiving plate having such a configuration is aligned with the single drive shaft 1. If three sets are installed, the drive shaft will rotate in a fixed direction.

Furthermore, in the case where the running water reciprocates, the drive shaft 1 continues to rotate in the clockwise direction in the figure in any of the running directions as shown in FIGS. 5 and 6. ..

The case where the direction of the running water is constant is considered to be an irrigation canal, a small river, etc., and the case where the running water reciprocates means the motion of waves on the coast.

The frame body 7 shown in FIG. 1 is formed in a stepladder type, but the structure of the frame body 7 such as using a float or installing long legs to be driven into the water bottom is arbitrary.

[0029]

[Effect of the device]

 According to the present invention, regardless of the flow rate, it is possible to easily install the power generation device in the place where there is running water, and it was not costly to use electricity conventionally as night lights, safety lights, advertising lights, etc. In such a place, there is an effect that an electric light source can be used, and there is an effect that it can be widely used as a small power generator for home use.
