Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-head hydraulic power generator, and in particular, water used for power generation is circulated and reused, and compressed air is blown to rotate the water in order to compensate for the low-head hydraulic power. The present invention relates to a low head hydroelectric power generation device that also uses the rotational power of an air turbine.

[0002]

2. Description of the Related Art Conventionally, as a movable power generator, a generator driven by an engine is often used.
Nothing using hydraulic power is found. In addition, in the conventional hydroelectric power generator, it is usual to discharge the water after use in a stationary form.

[0003]

However, such a hydroelectric generator is a stationary and large-sized facility and is not suitable for a mobile generator, and even if it is constructed as a mobile generator, there is a limit to the amount of water that can be used. In addition, there is a problem that it is difficult to treat the discharged water. On the other hand, the type of driving the generator by the engine has a problem in that it produces waste gas and noise and is not preferable in the living environment. An object of the present invention is to obtain a movable low head hydroelectric generator that is mobile and does not discharge water to the outside of the machine and does not generate waste gas or noise.

[0004]

In order to achieve the above object, in the low head hydropower generator of the present invention, a water tank is provided on a movable machine base, and water in the water tank is guided to the lower side of the machine base by a conduit. It will be able to generate electricity by introducing it to the installed hydroelectric generator, supply a part of the generated electric power to the electric motor installed on the machine base, and drive the pumping pump by this electric motor, and all discharged from the hydroelectric generator during power generation. The water of the above is circulated to the water tank through a pipe so that power can be continuously generated, and the machine base is equipped with an air turbine and a compressed air tank that obtain rotary power by blowing compressed air. The compressed air supplied from the tank rotates the air turbine so that the rotational power is transmitted to the main shaft of the generator so that the hydraulic power and compressed air can generate electricity.

The rotary power of the air turbine driven by the compressed air supplied from the compressed air tank is directly transmitted to the main shaft of the hydroelectric generator or is transmitted via a transmission mechanism such as a chain, a gear or a belt. It is the one.

The movable chassis is the chassis of a vehicle such as a truck that can be moved by power.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings in which embodiments of the invention are described. In FIG. 1, reference numeral 10 denotes an undercarriage of a vehicle 12 that can move by power such as a truck. The undercarriage 10 is provided with a water tank 14, and water in the water tank 14 is guided by a conduit 16 to the undercarriage 1.
It is introduced into the hydroelectric generator 18 installed below 0,
The water turbine unit 20 can be rotated to generate electricity. The water ejected from the nozzle 22 at the tip of the conduit 16 hits the blades of the water turbine unit 20 and is discharged into the spillage tank 24. Through the aquarium 14
It is supposed to be returned to the inside and recirculated. Therefore, the continuously generated electric power can be extracted to the outside. 6 is a front wheel of the vehicle 12, and 8 is a rear wheel.

The electric power obtained by the power generation is taken out from the output terminal 30 as shown in FIG. 2, but a part of the electric power is supplied to the electric motor M via the conductor 32, and the pumping pump P is driven by the rotational power. It Therefore, the water once stored in the water tank 14 is, as described above, the conduit 16 and the hydroelectric generator 1.
Since it circulates through 8, the water suction pipe 26, the water discharge pipe 28, and the water tank 14, the generated electric power can be continuously obtained without replenishing water from others.

As shown in FIGS. 1 and 2, an air turbine 36 is arranged near the hydroelectric generator 18, and compressed air supplied from a compressed air tank Ta and ejected from an air nozzle 38 hits the impeller. It is designed to obtain rotational power. The rotational power can be transmitted to the hydroelectric generator 18 via the belt 40, so as to supplement the hydraulic power with a low head.

The compressed air tank Ta may be replenished with compressed air or replaced with the compressed air tank Ta when the internal air pressure decreases due to the use of compressed air. Further, the air compression pump may be driven by an electric motor that is rotated by a battery or another power source to supply compressed air into the compressed air tank so that the air pressure in the compressed air tank is always kept constant. Well-known means can be adopted as these means, and detailed description thereof will be omitted.

In the above embodiment, the hydroelectric power generation device is installed in a movable vehicle, but instead of this, a stationary type may be used. Further, although the rotational power of the air turbine is transmitted to the hydraulic generator main shaft via the belt, it may be directly connected to the hydraulic generator main shaft without using a transmission means such as a belt. In the above-mentioned embodiment, the turbine of the hydroelectric generator shows an example of a so-called Pelton turbine in which water ejected from the nozzle collides with the impeller, but a so-called Francis turbine in which a water flow is passed between the impellers is used. It is also possible to do so. Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and it goes without saying that the present invention can be implemented in various modes without departing from the scope of the present invention. .

[0012]

Since the present invention is constructed as described above, it has the following effects. The pumped water pump is driven by the generated electric power to circulate water to generate electric power, so that electric power can be continuously obtained. Also,
Since the rotational power of the air turbine that rotates by compressed air is transmitted to the main shaft of the hydroelectric generator, it is possible to supplement the hydraulic power with a low head. Furthermore, unlike a generator driven by an engine, it does not generate waste gas, noise, etc., and thus can be a clean power source. Furthermore, since the water used for power generation is not discharged to the outside, no drainage facility is required and installation cost can be reduced.
