Description

The present invention relates to power generation for water turbine applications that uses the energy of the weight of water.

Renewable natural energy is currently expected as a trump card to prevent global warming by removing CO2 and removing nuclear power. Hydroelectric power generation is one of them, and has become an important renewable energy source. A hydroelectric power station creates a dam by blocking water in the mountains of a large river to increase the water pressure of the stored water and rotate a generator to generate electricity.Currently, small-scale power generators are also installed in small and medium rivers. Therefore, it is common to utilize the force and weight of water and the flow of water.

However, the current hydropower generation has insufficient water utilization. The water stored in dams is also used only once for power generation, and thereafter, most of the water is used as unused water, except for waterworks, industrial water, agricultural production, or fish farming. ing.

Further, in the present hydroelectric power generation, the utilization of the energy of the weight of water at a high place is not sufficient, so that the inventors have thought that there are various other effective utilization methods, and have reached the present invention.

For large-scale power generation using the head of water, there are existing hydroelectric power plants, but there is no place to create a new power plant in Japan today, and the existing dams accumulate sediment every year. Water storage is decreasing and water shortages are occurring due to climate change.

Also, the use of water at one dam of an existing hydroelectric power plant is one-time power generation, and for the next power generation, a dam is made downstream or a thermal power generation or a nuclear power generation that cannot stop power generation at night. Water is pumped up and reused by using excess electricity, but both methods increase maintenance costs and installation costs, and the use of energy equivalent to the weight of high water is insufficient. Seem.

As a solution to the problem, in the present invention, as a method of utilizing the energy of the weight of the water accumulated in a high position, the location of the turbine currently used is set to abrupt water with a steep slope from the riverbank where there is little head. Change into the mountain of a small river, hang the chain (4) on the upper large sprocket (1) that has been changed to a water wheel, and store water in the multiple water tubs (5) attached to the chain (4). In addition, by adding to the radius of the upper large sprocket (1), a gravity addition turbine that drops a plurality of water troughs (5) using the head is created to generate electricity. If such a method can be implemented, even though the amount of water required for power generation is smaller than that of conventional hydropower generation, the energy of the weight of water at a high place can be effectively used and more power generation capacity can be generated.

An ordinary water turbine has a limited amount of water that can be rotated by horsepower, and it does not produce a large amount of horsepower.However, a gravity addition turbine has a flow rate if a weir is created in a small river with abundant water in a high place with a slope. Depending on the situation, water can be piped in to install multiple gravity addition turbines, and if multiple gravity addition turbines are installed on the lower side of the turbine, stable and continuous, except for a decrease in water volume due to changes in the weather. Can generate electricity.

Most of the turbines currently in use are either constructed on a flat land that uses the flow of a river, or have a structure that sends water over the turbine at the sloping mountain hem, so the amount of water required for rotation is limited. The head is small. However, using a steep slope on the upstream of a small river with abundant water, a gravity addition turbine was installed, and water was drawn into the falling gutter (6) with a pipe, and a plurality of water tubs (5) attached to the chain (4) Although it descends after filling up with water one after another in the direction of upper travel, the number of water basins (5) is limited by the height in the gravity addition turbine, although the water storage capacity of one turbine is limited. However, since the size can be changed in proportion to the amount of water in a small river, the amount of water can be secured even if the head is small, and if there is a certain head, the weight can be secured and the amount of power generation can be secured.

A small dam is made upstream of a small river with a mountainous head and abundant water. A place where a gravity addition turbine can be installed with a pipe to abundant water of the Tanigawa, though there is a slope, but is suitable for the amount of water on the downstream side. ), the gravity addition turbine is arranged at a height below the head of the dam, and the pipe water is poured into the falling trough (6), and the water is always distributed to the multiple gravity addition turbines to the chain (4). The attached water tubs (5) are filled with water and used for power generation by rotating the gravity addition turbine, and the water used for power generation is returned to the original small river without any reduction in the amount of water returned. As for the installation cost required for power generation, the cost per site is small with a small device, and if there is a head, multiple stages can be installed and the cost of power generation will be further reduced, there are many places that can be installed nationwide, etc. The installation cost is lower because it is smaller than the power generation method, and once installed, the fuel cost for power generation is 0 yen no matter how many the number of units increases, and maintenance costs can also be checked at once if the cost is maintained in one place. Become cheap.

If there is more than a steep slope to the Tanigawa below the intake, use it with a gravity addition turbine, reuse the drained water and use it again for a gravity addition turbine, and there is more head. For example, it can be reused as many times as possible and returned to the original Tanigawa downstream. Large and small sprockets (1) and (2), chain (4) and water trough (5) can be used to adjust the amount of water by adjusting the intake of the weir and the falling gutter (6). Other than the above, it is possible to generate power continuously and continuously without any breaks.

Instead of a normal water turbine, two large and small sprockets (1) and (2) centered around the upper and lower shafts (3a) and (3b), a chain (4) surrounding the space between them, and the chain (4). Water troughs (5) attached at equal intervals are provided in the upper sprocket (1) near the upper sprocket (6). In the vicinity of (2), the water tub (5) in which water has accumulated reverses and rises by discharging water there, causing the chain (4) and the large and small sprockets (1) and (2) to rotate, A gravity addition turbine with the characteristic that power energy is generated from the force through the shafts (3a) and (3b).

The water collection situation at the top of the water tub (5) of the gravity addition turbine is shown in Fig. 2. The water from the spillway (6) that constantly falls in a wide range other than the intake (8) while rising and rotating is shown. , Even if the angle of the water tub (5) is changed by the rotation of the upper large sprocket (1), the angle of the water collecting vane (10) with the reversal angle (11) is kept constant by the action of the weight (12), The water collecting blade (10) collects water other than the water intake (8) and collects the water in the water tub (5). The water tub (5) fills up and moves downwards. The weight of water in 5) is added to the radius of the upper large sprocket (1) to increase the power generation capacity.

The water tank (5) of the gravity addition turbine is a combination of the water tank (7) and the water intake port (8) as shown in Fig. 3, the water intake port (8) is cut diagonally, and the water trough (5) is a falling gutter ( 6) Water collecting vane (10) with a movable reversal angle (11) that receives water other than the intake port (8) that constantly falls wider than the water collecting vane (10) and takes it into the intake port (8) Attach. When the water collecting vane (10) with the reversal angle (11) collects water, the water tub (5) changes its angle as the upper large sprocket (1) rotates. 12) Keep a constant angle. Therefore, the weight (12) which bears the weight of the falling water is provided, and the water collecting efficiency of the water collecting blade (10) is improved.

The water collecting vane (10) with a movable reversal angle (11) of the gravity addition turbine holds the water falling near the top other than the intake (8) by the weight (12) while rotating. It is received at the same angle, and the rotation time is adjusted so that the water tub (5) is full, and the water tub (5) is lowered when it is full, but the weight of the water in the water tub (5) increases and the upper sprocket (1) Weight can be added to the radius, creating more power.

In the vicinity of the large sprocket (1) on the upper part of the installed main body, it is movable to the outside of the water intake (8) of the trough (5) in order to increase the efficiency of water intake from the Tanigawa through the falling gutter (6). It has a rod (9) and a movable water collecting vane (10) with the movable rod as a fulcrum, and an inversion angle (11) integrated with the water collecting vane (10) on the opposite side of the movable rod. Gravity with a plurality of water troughs (5), which has a weight (12) that keeps the water collecting vane (10) at a certain angle during water intake and withstands the weight of the water collecting vane (10) due to water pressure and weight. Additive water wheel.

The position of the movable movable rod (9) of the water collecting vane (10) with the reversal angle (11) attached to the water tub (5) of the gravity addition water turbine is the same as the passage line for passing the sprocket in any water tub (5). As it passes through (14), the water tub (5) drains the water in the water tank (7) while advancing and reversing along the same passage line (14) when it comes near the bottom, but the angle changes due to the weight (12). Since the water collecting vane (10) with no reversal angle (11) closes the intake (8) as it is, the reversing pin (13) with a bearing fixed to the pedestal for reversing the water collecting vane (10) with the reversal angle (11) ), the water collecting vane (10) with the reversal angle (11) from A to F in FIG. 5 moves, and the water collecting vane is reversed to move up.

As for the traveling direction of the reversal angle (11), since the upper and lower sprockets (1) and (2) are rotating in the same direction, the traveling direction is reversed above and below where the chain (4) is applied, and the rotation progresses to the bearing. Entangled with the reversing pin (13), reverse the water collecting vane (10) with the reversing angle (11) in Fig. 4, open the intake (8), and raise the empty water trough (5) to the top. Then, while advancing the rotation near the uppermost part, the water collecting vane (10) with the reversal angle (11) and the water intake (8) were taken up, filled with water and descended, and the tub (5) emptied at the lowermost part again As it rises and continues rotating, power generation continues.

The reversing flow of the water collecting vane (10) with the reversing angle (11) of the gravity addition water turbine causes the reversing angle (11) to be entangled with the reversing pin (13) with bearing due to the rotation progress of the lower small sprocket (2) in FIG. The water collecting vane (10) moves in the state of reversal of the weight (12) from A to F in FIG. 6 and is entangled with the reversing pin (13) with a bearing, and the position of the weight (12) is the uppermost 180°. After passing D of 6, the weight (12) descends due to gravity, and since the water collecting vane (10) and the weight (12) are integrated, they are inverted to open the intake port (8), and hence the water collecting vane. At (10), water is ready to be collected, then rises toward the top sprocket (1).

Since the present invention is a generator that uses gravity of the weight of water as a power source, there is almost no cost for power generation other than the initial equipment installation cost and subsequent maintenance costs, and water can be supplied if it rains. Therefore, harmless high-altitude water energy is generated, and water can form rivers where there are mountains and rain, so high-weight water energy can be used to be generated one after another. The fuel cost is 0 yen. Also, since the installation location and maintenance are often near the marginal villages, we ask the local residents to cooperate, and the local residents can earn maintenance work and income while living in the area.

In the current society, the amount of electricity used is increasing year by year, but the population in mountainous areas and marginal settlements continues to decrease year by year, and the population decline cannot be stopped. There are many small rivers that are rich in water, and if cheap electricity can be supplied using the valley river, land can be acquired cheaply, companies can easily enter the market, the population decline can be stopped, and migrants will increase if there are jobs. However, if cheaper electricity can be generated and more jobs are created, both industry and households will be able to benefit from cheap electricity, and relocated people can also enjoy rural life, so young people can settle in the countryside and live in the countryside. Can also increase the population

Electricity for solar power generation and wind power generation is easily affected by the weather, and electricity for factories, large commercial facilities, offices, etc. that require high voltage or large capacity electricity does not have enough voltage or required capacity. I think that electricity from nuclear power generation is used as the main power source, but if the electricity of the gravitational addition turbine can generate electricity without being affected by the weather, a certain amount of electricity will be generated, unlike solar power generation and wind power generation, which are affected by the weather. Since stable power generation is possible at all times, the number of migrants will increase if factories can be built in marginal villages and places where local residents can work. Electricity generated in remote areas is transmitted to urban areas and factory areas by transmission lines, but if electricity is generated using an gravitational addition turbine, it will be generated near factories near the city, and transmission costs will be low.

FIG. 1 is an overall view of a gravity addition turbine according to the present invention.
In order to implement the present invention, there are plenty of water in the valley river, which has abundant water volume, small rivers in mountainous areas with different elevations, dams of existing power plants, and dikes for earth retaining works in mountain control projects. There are many places in, so all can be used. If there is a slope on the mountain and there is a difference in height, you can use it for power generation as many times as you like, as long as there is a margin in the head, by flowing water sequentially from the top to the gravity addition turbine.

Fig. 2 shows the water intake of the water tub (5) of the gravity addition turbine. The basin (5) of the gravity addition turbine is a form in which the water tank (7) and the intake (8) are united as shown in Fig. 3, and the intake is cut diagonally, and the basin (5) is a falling gutter (6). Since the water collecting wing (10) receives water other than the water intake (8) that is falling more widely than usual, a movable water collecting wing (10) with a reversal angle (11) is attached to the water intake (8). .. When the water collecting vane (10) with the reversal angle (11) is collecting water, the angle of the water trough (5) is changed by the progress of rotation of the upper large sprocket (1), but the water collecting vane (10) is moved to the weight (12). ) To maintain a constant angle. Therefore, the weight (12) that bears the weight of the falling water is provided to improve the water collection efficiency. The water collecting vane (10) with a movable reversal angle (11) of the gravity addition turbine is used to keep the water falling outside the intake port (8) near the top by the weight (12) while rotating. It is received at the same angle, the rotation time is adjusted so that the water tub (5) is full, and the water tub (5) is lowered when it is full, but the weight increases by the number of water tubs (5), so that the radius of the upper large sprocket (1) is increased. Weight can be added, and greater power is created. FIG. 4 is a state diagram when the water tub (5) of FIG. 3 is lowered.

FIG. 5 shows the positions (A to F) of the movable rod (9) at each angle formed between the position of the weight (12) and the vertical line of the ground. FIG. 6 is a flow chart of reversing the weight (12) when the movable rod (9) comes to each position (A to F) in FIG. The position of the movable movable rod (9) of the water collecting vane (10) with the reversal angle (11) attached to the water tub (5) of the gravity addition water turbine in FIGS. 6A to 6F is such that any water tub (5) is a sprocket. Since it passes through the same passage line (14), when it comes to the vicinity of the lowermost part, the water trough (5) advances and reverses along the same passage line (14) to drain the water in the water tank (7), but the weight (12) ) Does not change the angle, the water collecting vane (10) with the reversing angle (11) closes the intake (8) as it is, so the water collecting vane (10) with the reversing angle (11) is reversed and fixed to the pedestal. The reversing state of the water collecting vane (10) in which the reversing angle (11) is entangled in the reversing pin (13) with a bearing is the movement of the weight (12) from A to F in FIG. ) Entangled with the position of the weight (12) past the uppermost 180° Fig. 6D, the weight (12) descends due to gravity, and the water collecting vane (10) and weight (12) are integrated, so they are reversed and the intake ( 8) is released and the water collecting vane (10) is ready to collect water, and then it rises toward the uppermost sprocket (1).
