Description

  The present invention relates to a pumped hydroelectric power generation apparatus that is installed in the inland away from the vicinity of a river.

  BACKGROUND ART A pumped hydroelectric power generator that pumps surplus power at night and generates power in the daytime has been put into practical use as a large power storage device and is widely known. In addition, power storage using chemical batteries is common, but is not widespread due to maintenance costs.

  Small hydroelectric generators are installed in the vicinity of water currents. Similarly, wind power generation is unstable due to the large difference in power generation depending on the installation location.

  Power generation devices that use natural energy installed on privately owned land or building rooftops, etc., are required to generate electricity when electricity is needed, and require no fuel costs.

  Photovoltaic power generation is limited to sunlight, and the generated power is stored in a chemical battery and can be taken out at any time, but the chemical battery has a product life and requires maintenance costs.

  It is desired that the power source of a natural disaster area or construction site be moved by an existing transport vehicle and that it be a non-oiled power generation device that does not require special technology for maintenance.

  In order to achieve the above object, the present invention provides a pumped small hydroelectric generator according to claim 1 of the present invention, which is a self-supporting pumped hydroelectric generator that is movable and has a spiral shape with different diameters and different gradients. An impeller having a water pipe and an outer ring, a generator connected to a rotating shaft of the impeller, a solar cell panel, an electric pump, a water storage tank, and a storage tank are disposed, and an electric pump is generated by the generated power of the solar cell panel , The water stored in the water storage tank is pumped up and stored in the storage tank, and the impeller is rotated by a vortex flowing through the helical water pipe as needed, and the generator connected to the impeller is rotated. And is configured to generate electricity.

  Next, the pumped-storage type small hydroelectric generator according to claim 2 of the present invention is characterized in that the storage tank has a sealed structure.

  Next, the pumped storage type small hydroelectric generator according to claim 3 of the present invention is arranged such that the water storage tank, the storage tank, and the solar battery panel are arranged at appropriate locations according to the terrain and construction environment, It is characterized by being arranged so as to automatically supply reduced water in a water supply or the like.

  Next, the pumped small hydroelectric generator according to claim 4 of the present invention is characterized in that an antifreeze liquid is mixed into the circulating water between the water storage tank and the storage tank.

  According to the inventions according to claims 1 to 4, when the water stored in the high place is pumped with the power of solar power generation and is necessary in the same way as the storage battery, the stable power supply by the water turbine power generation using the head is provided. Can be made possible.

  In addition, even if the difference in level between the water level of the storage tank and the storage tank is 1 m or more, the height of the pumped-up small hydroelectric generator can be reduced to 2 m or less, so that the vehicle can be easily transported and moved.

  Suitable for electric vehicle charging stations, emergency power supplies / disasters / temporary power supplies, self-sufficiency power supplies / selling, and power distribution to multiple houses in underdeveloped countries, creating value for new lifestyles and new industries.

  According to the second aspect of the present invention, the air in the storage tank is compressed by making the storage tank hermetically sealed and pumping up with an electric pump. However, pressurization to a specified value compensates for a decrease in air pressure during power generation. Thereby, the electric power generation output of the generator connected with the impeller can be enlarged.

  According to the invention which concerns on Claim 3, the expense of maintenance management can be reduced by adding the apparatus which automatically supplies the water reduction by evaporation, a leak, etc. using a tap water, rain water, or groundwater.

  According to the invention according to claim 4, while extending the life of the equipment by mixing the antifreeze liquid into the water storage, the installation range is expanded from the rooftop of buildings and factories unrelated to hydroelectric power generation to the back ground of non-distributed agricultural and mountain villages, Moreover, since no fossil fuel is used, it is possible to provide a highly economical pumped-type small hydroelectric generator that is easy to handle, has little danger, and can be operated unattended.

It is a schematic block diagram of the self-supporting pumped-up small hydroelectric generator using solar power generation. It is a layout diagram showing a schematic configuration of a pumped-up small hydroelectric generator. It is a figure which shows the structure of a water wheel.

  The pumped-type small hydroelectric power generation apparatus that uses both solar power generation and pumped-storage power generation according to the present invention is self-supporting, so that an embodiment that generates power at a necessary time inland will be described based on drawings that are easy to understand. The present invention is not limited. In addition, the solar cell panel is assumed to be installed at an angle and a direction in which the output is greatly increased.

  The pumped small hydroelectric generator of this embodiment shown in FIG. 1 has a mechanism in which the solar cell panel 5 disposed on the gantry 1 can change the inclination angle to an appropriate position during operation and adheres to the main body during transfer. The water storage tank 7 and the storage tank 8 store the water to be circulated by mixing the antifreeze liquid, respectively, and the electric pump 6, the water wheel 2, the generator 4, and the accessories attached thereto are also arranged on the gantry 1 and are self-supporting structures. I am doing.

  The power generation capacity of the solar panel 5 is obtained by adding the loss products of the electric pump 6, the water turbine 2, and the generator 4 based on the power product required by the customer and dividing it by the sunshine hours. Based on this value, the capacity of the storage tank 8 and the storage tank 7 is determined, and the self-supporting form is stored based on this.

  The electric pump 6 is driven by the electric power generated by the solar battery panel 5, and the water in the water storage tank 7 is pumped to the storage tank 8 through the water absorption pipe 11. A backflow prevention valve 19 is provided below the water absorption pipe 11 so that water in the storage tank 8 does not flow into the water storage tank 7 through the water absorption pipe 11.

  When the drainage valve 17 is opened, the water in the storage tank 8 passes from the storage tank 8 through the introduction pipe 3 having the electric valve 16, passes through the water wheel 2, rotates the impeller built in the water wheel 2, and is connected to the impeller. 15 rotates and the generator 4 rotates by the conductive belt 14 to generate electricity. The water rotating the impeller is discharged from the water discharge pipe 29 to the water storage tank 7 and reused as circulating water.

  When the electric valve 16 of the introduction pipe 3 to the water turbine 2 disposed at the bottom of the storage tank 8 is opened by a signal, power generation is started and necessary power is obtained, and when it is closed, power generation is stopped.

  The drainage pipe 9 provided in the storage tank 8 has a function of keeping the stored water at a certain level, and has an inlet 10 for supplementing the antifreeze liquid to the water storage tank 7 and reducing the water content. In order to protect the equipment, anti-freezing liquid is mixed appropriately according to the weather conditions of the installation site to increase antiseptic and cold resistance.

  On the gantry 1 of the pumped-up small hydroelectric generator, there is arranged a device that efficiently controls the equipment, a device that displays the operating state, enables manual operation and operation, and a control panel 12 that collectively stores disaster prevention and security equipment. Has been established.

  When the generated voltage of the solar battery panel 5 is lower than the set value, the storage battery of the power source for controlling various devices is charged, and when the set value is exceeded, the electric pump 6 is operated to circulate water in the water storage tank 7. Is stored in the storage tank 8.

  By changing the proportion of antifreeze circulating water according to the installation location, it can be installed in a wide range of land by preventing freezing at low temperatures and protecting the equipment.

  The water wheel 2 of the pumped hydropower generator of the present embodiment shown in FIG. 2 is composed of an upper part, a middle part, and a lower part, and the upper part is provided with a guide plate 22 that promotes rotation in a hanging water flow. A spiral plate 25 having a different gradient is disposed between a water pipe 26 having a different diameter, which is gradually narrowed and widened in the lower part, and a straight pipe 24 disposed in the center, and an outer ring 27 on a rotatable rotating shaft 21 at the lower part. The rotating shaft 21 has a pulley 15 for the conductive belt 14 that passes through the center of the water pipe 26 and passes through the waterproof packing 23 to be transmitted to the generator 4.

  The water pipe 26 gradually narrows the cross-sectional area with respect to the passing water flow, thereby gradually speeding up the rotation of the vortex. At the outlet of the water pipe 26, it spreads radially by centrifugal force, and the impeller 28 having the outer ring 27 enters the vortex. Since the rotating generator 4 is rarely countered, the connected generator 4 can obtain a high output.

  By setting the lower limit of the conventional head to 1m, the height difference between the water level of the storage tank and the water storage tank should be 1m or more, so the equipment is installed on the gantry so that the height of the device is within 2m. By doing so, it becomes independent and can be transported.

  The impeller 28 rotates at a high speed when the generator 4 is unloaded and consumes water wastefully. Therefore, the current consumption is monitored, the load is switched to the internal load resistance to slow down the rotation, and water is saved. Stop power generation.

  The biggest feature of the pumped-storage type small hydroelectric generator of this embodiment is that the energy source is free sunlight, it is safe with little maintenance, and it can generate electricity at the necessary time when needed. It should be noted that since it is only a visual inspection for water leakage, specialized knowledge is not required and a highly economical pumped-up small hydroelectric generator can be provided.

  The solar panel 5 can be installed in areas other than snow and shade, so it can be installed in the majority of non-distributed areas, and the effective use of land is a pumped-up small hydroelectric generator that leads to industrial creation and entrepreneurship. .

  Examples of the use of pumped-up small hydroelectric generators include power supplies for vending machines beside roads, charging stations, road stations, vegetable markets, small stores, private power supplies and time-sold electricity in buildings, vacant lots, and nighttime in parks and campsites. Lighting, monuments, and self-sustaining mobile types include emergency power supplies, emergency power supplies, disaster power supplies, various on-site power supplies, and event power supplies.
