The other claims are similarly treated as primary except for auxiliary ones.

In addition, as auxiliary equipment, a pressurizing pump, check valve, assist motor, push-up spring, swing pulley, air chamber, etc. were installed in the water intake pipe to facilitate the start-up and unstable times of the equipment.
However, since there are a wide variety of auxiliary devices, they are not included in the claims other than the main ones.

Furthermore, the difference between the heavy piston 5 and the heavy piston with float 6 is whether the piston alone floats.
The heavy piston only lowers due to its weight, and opening the piston opening valve can only drop service water.
In order to ascend, a float is attached to the lower part, or an auxiliary device is used to raise it. Although it cannot be raised by itself, it is the most important device for sucking up and sucking this device, and it is claimed as claim 6 alone.

The present invention relates to a hydraulic power generator in which a weighted piston is incorporated in a hollowed housing, water for power generation is sucked in by a change in volume as the weight piston descends, and an impeller for power generation is rotated by the fall of the suction water.

In hydroelectric power generation, a heavy weight piston is incorporated into a hollow housing, and power generation water from oceans, rivers, lakes, marshes, ponds, artificial ponds, etc. is sucked in by the volume change of the weight piston descending, and the suction water falls into the water for power generation. There was no way to rotate the impeller.

Patent No. 5935034 Body structure, Patent No. 5019246 Fig. 3 Compressor shape.

A heavy weight piston is incorporated into a hollow housing, and when the weight piston descends, the volume change causes the water for power generation outside the housing to be sucked in through the intake pipe, and the piston opening valve attached to the heavy piston is opened, or the water is sucked in through the gap when the piston descends. Water is dropped, and the impeller for power generation is rotated by the water drop pressure during the water drop process.

Furthermore, the outside of the housing is closed, and the water for power generation under the housing bottom is sucked through the water intake pipe due to the volume change of the weight piston descending, and the impeller for power generation is rotated by the falling water pressure during the water falling process.

Furthermore, in shallow water, the weighted piston is incorporated into a hollow housing submerged in shallow water, and the volume change of the heavy piston descending causes the upper part of the housing to absorb water for power generation and open the piston opening valve attached to the heavy piston, or When the piston descends, the suction water is dropped from the gap, and the impeller for power generation is rotated by the water drop pressure during the water drop process.
In addition, air was filled between the piston and the impeller for power generation so as to reduce water resistance in the up-and-down action of the piston in water and the rotation of the impeller for power generation.

Furthermore, the piston is changed to a horizontal piston, a pendulum piston, a swing piston, a seesaw piston, a rotating impeller, etc., to improve the efficiency of water intake and discharge for power generation.

In addition, as auxiliary equipment, a pressurizing pump, check valve, assist motor, push-up spring, swing pulley, air chamber, etc. were installed in the water intake pipe to facilitate the start-up and unstable times of the equipment.

As shown in FIGS. 1, 2 and 3, in a hollow housing 1 including a housing drum 2 corresponding to a cylinder of a piston engine, a housing head 3 corresponding to a piston head, and a housing bottom 4, located above the water source for hydroelectric power generation. , the floating heavy piston 6 is assembled and placed at the upper position, the water intake valve 8 is opened, the floating heavy piston 6 is lowered by its own weight, and the water for power generation is sucked through the water intake pipe 14. As the floating heavy piston 6 is lowered, the water intake valve 8 is closed, the piston opening valve 9 is opened, the suction water is dropped and stored on the housing bottom 4, and the buoyant force of the push-up float 12 due to the accumulated water on the housing bottom 4 returns the weight piston 6 with the float to the upper position before it is lowered, and opens and closes. A method is adopted in which the plate 10 is opened to allow the accumulated water on the housing bottom 4 to drop, and the impeller 7 for power generation is rotated.

The content of rotating the power generation impeller 7 by the action of the floating weight piston 6 is as follows.

The lower part of the floating heavy piston 6 placed at the upper position is emptied, and the water for power generation outside the hollowed housing 1 is drained by the self weight of the heavy piston 6 from the upper position and the increase in the weight of the suction water due to the change in volume. A method of sucking into the upper part of the heavy weight piston 6 with a float was adopted.

As the weight piston 6 with a float descends, the piston opening valve 9 is opened to drop the suction water and store it on the housing bottom 4 . After returning to the balanced position, the opening/closing plate 10 is opened to let the accumulated water on the housing bottom 4 fall, and the impeller 7 for power generation is rotated.

Furthermore, as shown in FIGS. 4 and 8, the outer periphery of the hollow housing 1 is closed, and the accumulated water in the lower part of the housing bottom 4 is removed by the suction force of the upper volume change due to the descent of the floating heavy piston 6. As a method of internal water intake impeller rotating device that sucks up water, it can be used regardless of whether it is above water or underwater.

Furthermore, as shown in FIGS. The underwater impeller is pushed down by an increase in upper water pressure, pushed up by a decrease in upper water pressure due to the closing of the water intake valve 8 and by air buoyancy at the lower part, pressurizes the upper water of the heavy piston 5 and discharges it to the lower part, and rotates the impeller using the discharge pressure. With the method of the car rotating device.

Furthermore, as shown in FIGS. 6, 7, and 8, the underwater impeller rotating device is reversed, and the air buoyancy and volume change inside the heavy piston 5 that sinks to the bottom opens the check valve 30 and sucks in the air outside the housing. A buoyancy impeller that floats the heavy piston 5, discharges the sucked air to the top by opening the piston opening valve 9 and lowering the weight of the heavy piston 5 after the heavy piston 5 floats, and uses the buoyancy of the discharged air to rotate the impeller. A rotating device method was adopted.

Further, as shown in FIGS. 7 and 8, the hollow or underwater hollow housing impeller rotating device is combined in the upper part, and the underwater hollow housing buoyancy impeller rotating device is combined in the lower part. method.

In addition, as shown in FIGS. 9 and 10, the piston pump device by the weight piston 5 of the up-and-down repetitive motion was changed as follows to improve the efficiency.

The seesaw plate 38 is used as a pump device, and the push-up force and the push-down force are distributed and equalized with the axis as a boundary, and the seesaw action can be performed by pressurization of either left or right push-up/down, and water is taken in both of the distributed seesaw plates 38. A method of pumping action by alternately opening the valve 8 and dropping the water, and changing the volume of the seesaw plate by pistoning at both ends.

The impeller 39 is used as a rotary pump device, the buoyancy from below is distributed by the shaft, and the left and right horizontal balance is maintained, and the water intake valve 8 is opened to one of the rotary blades distributed via the shaft to apply water pressure from above to the impeller. A method of continuously rotating a rotary pump.

The power generation impeller 7 or the impeller 39 is a gravity tiltable impeller 48 incorporating a gravity tiltable blade 47, a gravity tiltable impeller 50 incorporating a gravity tiltable blade 49 that falls to the outside of the rotating body and has less rotational resistance, Gravity outward tilting blades 51 with a wide fallen water receiving area are incorporated outside the rotating body to form a gravity outward tilting impeller 52, and a tiltable blade capable of tilting in the gravity direction by gravity is incorporated, and the upper part tilts as the impeller rotates. A method of folding blades that sometimes receives falling water from the upper part and pushes the falling water to the lower part when the lower part is folded.

Furthermore, the structure of the buoyancy cavitation falling water power generation device of Japanese Patent No. 5935034 uses the falling water acceleration pressure and requires a vertical depth, and it was difficult to suck in the power generation water against the lower buoyancy pressure at the time of water intake. As described above, since the water intake device with a structure that is labor-saving and miniaturized is used, the direction of gravity is shallow and it is possible to extend in the horizontal direction. A method of securing a water source for a shallow irrigation channel accompanying the continuous arrangement of the hollowed housing 1 was adopted.

As for the gravity piston 5 and the weight piston 6 with float, which are repeated up and down, the pressing force is reduced for each repetition, and the power load for sucking the water for power generation and falling into the water is reduced.

As for the horizontal piston 40 and pendulum 41 device, since the horizontal piston and pendulum reciprocate left and right, buoyancy and spring support from below are no longer necessary.

As for the device of the swing plate 37, the tip of the swing plate is made into a piston to simplify the spring support on one side, thereby reducing the structure and narrowing the space.

With regard to the seesaw plate 38, the upward force and the downward force are evenly distributed on the axial boundary, and the alternate opening of the upper left and right water intake valves 8 allows the upper alternating water pressure to be used as a seesaw repeated pump.

The impeller 39 can be rotated by upper water pressure by opening the water intake valve 8 on one of the left and right sides of the upper part by equally dividing the axial boundary of the upward force and the downward force.

Furthermore, the construction cost is low as a hydraulic impeller rotating device, and the running cost is low due to the reduction of power other than the start-up and operation assistance during unstable times.

In addition, as described above, the shallow hollow housing and the horizontal continuous arrangement of the shallow hollow housing can secure the water source for the artificial irrigation canal, and secure inexpensive hydroelectric power generation by reducing the construction cost of the power generator and the cost of large-scale deep excavation. was realized.

In addition, it became possible to use the discharge water for agricultural and industrial purposes.

Furthermore, as a device that does not use fossil fuels, it leads to a reduction in carbon dioxide, and as a device that does not use nuclear power, it has become possible to avoid radioactive contamination.

Furthermore, this device is also a power generator and a rotary power device, and can be used as a rotary power device in ships and the like.
