Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an apparatus for generating electricity by using external air suction by a water jet. 2. Description of the Related Art Conventionally, various power generation systems have been put to practical use. However, as shown in the present invention, power generation systems and devices utilizing air suction by a water jet have not been found at present. [0003] Power generation systems that have been conventionally used include hydroelectric power, thermal power, nuclear power, geothermal power, wind power, solar light, waves, and tide. Although each has advantages and disadvantages, wind power and solar power have recently gained traction as clean energy. Among them, wind power generation is a method in which a windmill is turned using natural wind, and a generator is connected to the windmill (blades) to generate power. In recent years, its installation tends to increase. However, the wind from which wind power is generated depends on weather conditions and the like, and has the following problems. 1. Since the wind power is affected by weather conditions, the wind power is not stable, and the power generation fluctuates. 2. Blades and related equipment must be installed on tall towers, and the area where winds blow well must be selected and installed. 3. To secure a certain amount of power generation requires a large number of windmills and a large area of land. 4. For installation, time and
It requires labor and expense. 5. Installation costs are high. The present invention has been invented in order to solve the problems related to the conventional wind power generation as described above, and provides a power generation device capable of easily obtaining stable power using a water jet. It is intended. [0004] As a means for solving the problem, the present invention provides a method in which outside air flows in under a negative pressure in an ejector,
The basic configuration is to generate electricity using wind power from the outside air, that is, a pump is connected to an ejector that takes in and discharges outside air with negative pressure due to high-speed water flow, and a separate pipe is connected to the outside air inlet of the ejector. Is connected, a wind turbine is interposed in the middle of the pipeline, and a power generation mechanism is attached to the wind turbine, so that the wind turbine is turned by the wind power of the outside air flowing in due to the negative pressure of the ejector to generate power. The present invention is a water jet power generator configured as described above. [0005] In order to use the present invention, first, water is stored in a tank by a water supply pipe. Next, when the pump is driven, water is supplied into the ejector and discharged as a high-speed water flow. At this time, a negative pressure is generated in the ejector, and outside air flows into the ejector by the negative pressure. This inflow passes through a pipeline, and a windmill is provided in the middle of the pipeline, and a generator is attached to the windmill. Therefore, power is generated simultaneously with the rotation of the windmill, and the original purpose can be achieved. The pump is connected to a separate hydroelectric generator or an external power supply to supply power. An embodiment of the present invention will be described below. FIG. 1 shows a connection system for each device, and FIG. 2 shows an ejector. In the figure, 1 is a filter for removing outside air dust, 2 is a windmill and a generator, 3 is an ejector, 4 is a charge tank, 5 is a pump for water circulation, 6 is a control panel, and 7 is a hydroelectric generator. The line between the filter and the ejector is connected by a line 10, the line 11 between the ejector and the charge tank, the line 12 between the charge tank and the pump,
The pump and the ejector are connected by a pipe 13.
Further, a water supply pipe 14 is connected to the charge tank. In the above pipeline, the pipeline 10 is an air passage pipeline, and the other pipelines are water passage pipelines. The wind turbine / generator and control panel, the hydraulic generator and control panel, and the pump and control panel are each connected to form an electric system. The connection 19 indicated by a dashed line is an external power connection for supplying power to the pump when the hydroelectric generator is not used. Next, the ejector mechanism will be described. In the figure, reference numeral 20 denotes a cast iron casing, in which an outside air inlet 21 is provided at an upper portion, a water inlet 22 is provided at a left side, and an outlet 23 is provided at a right side. A nozzle tube 24 and an inner cylinder 25 are provided in the casing. Although the nozzle tube has a substantially cylindrical shape, the right end thereof is narrowed to have a small inner diameter. The inner cylinder is a cylinder of an appropriate length. The nozzle tube and the inner tube are appropriately mounted in the casing by a supporting member, and the right end of the nozzle tube and the left end of the inner tube are provided close to each other so as to be located on substantially the same plane.
The water sent from the pump flows into the casing from the water inlet, jets out of the nozzle tube as a high-speed water stream, passes through the inner cylinder, and is discharged from the right outlet. At this time, a negative pressure is generated according to Bernoulli's principle, that is, the inside of the casing has a negative pressure, so that outside air flows in from the outside air introduction port, and this outside air is sucked from a gap between the right end of the nozzle pipe and the left end of the inner cylinder, and high-speed water flow is generated. And is discharged from the outlet. Therefore, the outside air flows in along with the water injection. The outline of the present invention is as described above, and the mechanism of the present apparatus is as follows. When the pump is driven after storing the water in the charge tank, the water in the tank passes through the pump via the pipe 12 and reaches the ejector via the pipe 13. The water that has passed through the ejector returns to the tank again via line 11. That is, the water in the tank circulates. In the ejector, a negative pressure is generated by the above-mentioned action, and the outside air passes through the filter through the pipe 10 and passes through the inside of the ejector, enters the charge tank, returns the water to the tank, and the outside air flows out of the hole provided in the tank. Sent out. A windmill is interposed in the pipeline 10 and a generator is connected to the windmill. Therefore, power is generated along with the rotation of the windmill, and the power is transmitted to the outside via the control panel at the connection 15 and the power transmission connection 18 at the connection 15. In addition, although electric power is required for driving the pump, in this example, a hydroelectric generator is separately provided, and power generation from now on is sent to the pump to drive the pump. In other words, this hydroelectric generator is installed at a flowing water location to generate power. In this example, a system that supplies external power to the pump without using a hydroelectric generator was also made possible. Any number of windmills / generators can be used. As described above, according to the present invention, power is generated without using natural wind, so that stable power generation can be obtained. The present invention has the following effects. 1. Since the wind power is artificially generated, the air flow is constant and the power supply is stable. 2. Because it does not use natural wind, it is not limited to the installation location. 3. The energy sources are water and air, and no harmful gases are generated, and they are clean. 4. The installation location is free, and long-distance transmission lines are not required. 5. Can be manufactured relatively inexpensively. As described above, stable power can be provided by clean means according to the present invention.
