Description

The present invention relates to a pipe-shaped screw pump that is a pumping pump that uses natural energy such as photovoltaic power, wind power, small hydropower, and wave power as a driving force, draws water from a lower water source, and pumps it to an upper water storage tank.

Since ancient times, screw pumps (such as the Archimedes pump) have been used as pumps for irrigation and drainage. The power source has developed into human power, horsepower, wind power, electric power and so on. An ancient Archimedes pump (see, for example, Non-Patent Document 3).

Modern screw pumps are large in size and are characterized by using sludge pumping, rainwater drainage, pumping / relaying sewage treatment plants in harsh environments, and using a power source as electric power (see Non-Patent Document 1, for example).

However, the pumping angle of the screw pump is approximately 30 ° to 40 ° from the horizontal. The head is allowed to bend depending on the diameter and length of the screw pump, and is determined by other installation environment. The small size is 2 to 3m and the large size is 7 to 8m. Used at low head.

This is a structure in which priority is given to the efficiency of the pumped amount, and a high head is not intended, and there is a possibility of a high head when the pumping limit angle is examined in FIG. 12, FIG. 13, and FIG.

The conventional screw pump described above is intended for large yields and not for high heads.

The above-mentioned wind pumped storage power generation system passes through the wind turbine unit, pumping pump unit, and check valve, so that it is necessary to clean the pumping to some extent, and it is possible to generate stable output by storing water at the top and generating hydroelectric power. The structure of what to do is complex.

The above-mentioned combined power generation device of the solar power generation device and the wind power generation device makes effective use of the installation area, but the use of the electric power charged in the power storage device makes it closer to the electric user and the night illumination device becomes more effective Used in.

The present invention relates to a pumped-storage power generation apparatus and a pumping-pump apparatus for assisting the pumped-storage power generation system capable of simple and stable output power generation with a structure that uses the natural energy required by the conventional invention to the maximum and stores the energy in the form of natural energy. It aims at realizing.

And, in order to achieve the above object, the present invention connects the required number of pipe-shaped screw pumps with a connection ring that pumps water from the lower to the high place within the connectable range, forms a high head, and connects it to the lowermost end. As the power to drive the upper water storage tank and the pipe-shaped screw pump that has a pumping drain outlet at the top end and temporarily stores the pumped water, the rotational force by the main shaft with the one-way rotation clutch connected to the solar power generator and the wind power with the one-way rotation clutch A main shaft with a one-way rotation clutch connected to a transmission windmill blade unit or a wind power generator and a water wheel with a one-way rotation clutch by flowing hydraulic power or wave power are provided, and each natural energy is converted into rotational power and the rotational force is used via a connection ring. A pipe with a connecting ring that rotates and pumps a pipe-shaped screw pump when there is one or more inputs from three types of natural energy The other pumped drive source that rotates the screw pump and pumps water is a pipe-shaped screw with a connection ring that makes the operating time of the pump longer and the output source the same by three-system parallel input where the one-way rotary clutch operates and idles. Creating a pump.

Pumping water stored in the upper water storage tank grasps the amount of water with the level sensor, passes through the flow control valve from the water discharge pipe, and is discharged after generation by the hydroelectric generator. Power can be generated from the pumped water amount, drainage amount and the remaining capacity of the upper water storage tank in minutes. A number of pipe-type pumps for pumping that can be predicted in quantity are installed and one upper water storage tank is used as one system of hydroelectric power generation. For example, the amount of water stored in 24 hours a day is generated within the required time of the next day. it can.

Regarding the creation of a pipe-shaped screw pump with a connection ring, which is a pumping pump, the outer diameter of the main pipe and the shape and size ratio of the screw blade are a guideline for the main body pipe and screw body with screw blades fixed to the outer periphery of the main body pipe. Assuming that the outer diameter of the main pipe is d and the height of the screw blade is K, K = d × (0.15-0.2), the outer diameter of the screw blade is D, D = d + 2K, and the screw blade pitch is P, P = K × (0.6 to 0.9) or so, the screw lead angle is approximately 2 ° to 2.5 ° at the center diameter (d + K) of the screw blade height. When the split cover is detachably mounted, a screw groove is formed. The screw pump is assumed to be upright at 90 °, and the lead angle is approximately 2 ° to 2.5 °. When the lead angle is about 85 °, the pipe-shaped screw pump is horizontal when the lead angle is about 85 ° and the angle is about 5 °. Can make a pipe screw pump that can pump water at an inclination angle of about 80 °.

The pipe-shaped screw pump pumps water at an inclination angle of about 80 ° from the horizontal, but is a screw hump, so it has a check valve function and is suitable for cases where rotation frequency is high when driving unstable natural energy. Since the angle is small, the rotational torque is small as well as the fine screw.

The pipe-shaped screw pump is made to the required length, and the connection ring A is fixed to the upper end of the first stage, the connection ring B is fixed to the lower end, and the connection ring C is fixed to the upper end of the second and subsequent stages. The connection rings A, C, and B that form the screw pump unit with the connection ring have the same screw groove as the cross-sectional shape obtained by cutting the pitch length of the screw blade of the pipe-shaped screw pump into two parts and connecting rings. A or connecting ring C and connecting ring B are fitted with a centering spigot, and connecting ring A or C and connecting ring B have a larger outer diameter than the outer peripheral divided cover that forms the screw groove, and a connecting bolt hole The outer peripheral surface and the side surface can be used as a rotation guide for a pipe screw pump, a rotation guide for a wind turbine blade, and an external input / output interface. The connection rings A, C, and B have an inner diameter smaller than the inner diameter of the pipe-shaped pump body, and a plurality of screw pump units with connection rings having screw grooves are provided around the load receiving connection bolt of the screw pump unit. A pipe-shaped screw pump unit with a connecting ring, which can be used for a rotation guide of the screw pump unit and an external input / output interface and the like while obtaining a predetermined height or length without impairing the screw pump function.

Since the pipe-shaped screw pump unit of the present invention is used by being connected vertically, there is little bending in the length direction due to its own weight, a long pump unit can be obtained, a high head can be obtained, and the installation space can be saved.

Three types of energy sources (sunlight, wind power, hydrodynamic power) such as the rotational force by the power generated by the solar power generator, the rotational force of the windmill blades, the power of the separate wind power generation and the rotational force of the turbine are converted into parallel rotational force. By rotating the pipe-shaped screw pump unit to be converted and rotated, stable hydropower generation is possible while temporarily storing the lower aquarium or pond, river, seawater, etc. in the upper reservoir as the potential energy of the water. The amount of water remaining in the upper reservoir can be grasped with a level sensor, etc., so that the amount of power generation can be controlled in units of minutes to hours within the range of the amount of water stored, and it can be used as a peak power source when necessary.

The present invention is capable of securing, distributing, and watering the original agricultural water in addition to the pump for the pumped-storage power generation. In seawater, it is possible to supply seawater necessary for the onshore cultivation of seafood. In ponds, a cylindrical partition is installed around the intake from above the surface of the water to below the surface of the water. The return flow of the drain port becomes a downward flow, and a circulation flow of pond water is generated, which can also be used as a water circulation device that can also serve for purification such as oxygen supply.

In addition, when there are many pumping screw pumps installed in rivers due to heavy rain due to bad weather, the pumping pump pumps the river water with the power of the power storage device stored when power generation is possible and connects it to the upper reservoir or it. It is possible to reduce the water to prevent flooding the river by draining and sending water to other reservoirs.

The upper reservoir is located at a relatively high place, has position energy, has a pumping action due to water pressure, and has the ability to supply water, and can be used as emergency water such as water for extinguishing nearby fires. It can be used as emergency water other than water.

The upper water tank 60 in FIG. 1 temporarily stores water from which the pumped water is drained from the uppermost part of the pipe-shaped screw pump unit 10 (hereinafter referred to as a screw pump). The upper water tank and the flow cover B62 in FIG. The screw pump 10 suspended from the load receiving fulcrum shaft 12 fixed to the load receiving bracket 71 and the flow cover A61 attached to the connecting ring A10a and the screw pump unit 10 are fixed in a non-contact manner with a gap. The upper water tank is mounted on the upper part of the column main body 70, and is discharged to the upper side of the water supply surface through the water discharge pipe 91, the flow rate adjusting valve 92, the hydroelectric generator 90, and the drain pipe 93 that are engaged from the bottom of the upper water tank 60. The In addition, an upper / lower limit sensor or a water level meter (not shown) is attached to the reservoir.

The capacity of the one upper reservoir 60 is set according to usage conditions, and a plurality of the pipe screw pump units 10 are arranged in parallel at intervals where they can be installed, and upper reservoirs can be connected at the same time. The depth of the upper reservoir is shallow and the water pressure is reduced to reduce the mass of the upper part of the frame. It is desirable that the water storage is used up for one day. The space below the tank is used for other purposes or is a free space. Depending on the amount of stored water, it is equipped with water discharge pipes, flow control valves, hydroelectric generators, drainage pipes, electric control devices, and power storage devices in one place through a water pipe from the upper water tank to a remote large water tank or pond. It is possible to equip each device that can control the power generation amount. If the water supply method is a reverse siphon, there will be little decrease in the water level even when remote.

The pipe-shaped screw pump unit 10 of the present invention includes a solar power generator 50, a DC motor 13 connected to the solar power generator 50, a wind turbine blade unit 30 using wind power, a wind power generator and the DC motor 13 connected thereto, hydropower (wave power, river water flow), and other turbines.

The above three kinds of natural energy are converted to the potential energy of water through one pipe-shaped screw pump unit 10 (hereinafter referred to as screw pump) using natural water. It is expected that the operating time of the screw pump 10 by the three-system parallel input will be significantly longer and the movable efficiency will be improved.

The pipe screw pump unit 10 according to the present invention is installed on the shore, with a floating mooring system in mind, but is fixed on the shore and is a water circulation system. In addition, the method of installation differs depending on the weather, geographical conditions, etc. in the pond and lake.

The pipe-like screw pump unit 10 of the present invention is capable of securing, distributing, and watering the original agricultural water in addition to the pump for pumping power generation. In seawater, it can supply the seawater necessary for onshore aquaculture. For example, by installing a cylindrical partition around the water intake from the top to the bottom of the water intake, a gentle upward flow of pond water is generated, and the return flow of the drain port becomes a downward flow, resulting in a pond water circulation flow and purification of oxygen supply, etc. It can also be used as a water circulation device that can also function.

In addition, when there are many pumping screw pumps installed in rivers due to heavy rain due to bad weather, the pumping pump pumps the river water with the power of the power storage device stored when power generation is possible and connects it to the upper reservoir or it. It is possible to reduce the water to prevent flooding the river by draining and sending water to other reservoirs.

The pump of the pipe screw pump of the present invention is installed at a relatively high place, so it has potential energy, has a pumping action by water pressure, has a water supply capacity, can also use the lower water tank, and can be used as a water resource in an emergency For example, in the case of a large earthquake, when gas, water, and electricity are stopped at the same time, and a fire breaks out, there is a possibility that fire extinguishing activities can be performed quickly if there is a relatively large reservoir. Nighttime lighting and charging of mobile phones are possible with power storage devices stored in normal times. If it is not an emergency, there is a possibility of generating profits from selling electricity using natural energy.
