Abstract

PROBLEM TO BE SOLVED: To provide a water power-driven siphon type water turbine power generation equipment which maintains siphoning operation only by pouring water into a water tank, in order to solve the problem of a conventional large siphon type equipment that requires a pump to start the siphon for vertically raising the water level.SOLUTION: A water intake valve is provided below a tower for storing water, and the valve is set so as to be released when the amount of water in the tower is reduced. Water drop is prevented by partitioning siphon pipes 3A, 3B in a siphon pipe 3C in a tower for storing water. Similarly, tanks 4C, 4B, 4A prevent water drop. The water tanks 4 also form air retention sections. An air retention sensor is mounted on each of the tanks 4, and when air retained in the tanks 4A, 4B, 4D is released, each of stop valves 9A, 9B, 9D is closed, and by opening an air release valve 6, water is supplied from a water-supply valve 5. When the tanks become full, the valves 5, 6 are closed, and the valves 9 are opened to maintain the siphoning operation. Thus, the power of the siphon is maximized.

Description

As global warming continues, the development of clean energy is urgent. Providing hydro-powered siphon type equipment that can respond to this. This equipment is a hydro-powered siphon type equipment that generates electricity by placing both a water intake and a water outlet under the surface of the water, installing a water turbine on the side of the water outlet, taking out the splashing part of the water wheel from the surface of the water, and attaching a drain valve on it. is.

Hydro-clean energy, on a large scale, produces dams in rivers and builds waterfalls to places where they can fall, generating water turbines. There is also water being discharged for the downstream environment.

Medium- and small-scale hydropower generation uses the difference in water level (head), but there are water channel type, reservoir type and regulating pond type methods, but hydropower generation uses water level (head). The problem is that there are few places to take off.

JP-A-5-148826 (A), paragraph number 0006 Japanese Patent Laid-Open No. 5-157038 (A), paragraph number 0018

In conventional large-scale power generation, there is water that must be discharged because of the environment downstream of the dam, and the cost of constructing zuidou is very high.

Small- and medium-scale power generation is a method of generating water using a water pressure pipe by constructing a water intake facility up to a place where the water level on the intake side and the water level (fall) on the drain side can be taken. An irrigation channel is provided and a hydraulic pipe is used. Conditions such as whether or not the area is inundated during floods affect the layout of hydropower facilities. As mentioned above, the installation location of small and medium-scale power generation is limited.

In the case of seawater, there seems to be a power generation method that uses the tidal level, but there are problems with efficiency.

Inside the dam's dam, there will be a tower for water and siphon tubes 3A, 3B and 3C. Set up 4B and 4C tanks at the top, take out 2B siphon pipes to the outside of the dam, install the siphon pipes 2A and the water tank 4A, and place the splashing part of the watermill under the dam dams from the water surface. If 7 drain valves are installed on the top to generate electricity, the discharged water can be used effectively.

In the case of large, medium and small scale power generation, as shown in Figs. 3 and 4, the water level on the intake side and the water level on the drain side can be accommodated. The reason is that when the water is filled in the tower and the 7 drain valve is opened, the weight of the water in the tower makes use of the characteristics of the water flowing through the siphon pipe and the lower the water level. It can be adapted to the installation location by raising or lowering the large and small towers of the piping on the intake side and drain side.

When using seawater tidal, as shown in Figs. 5 and 6, two dams are lined up in the sea, each sluice is installed, the sluice is tightened at high tide, and the tide level (head) inside and outside the dam is about 60cm The siphon is started when it becomes. At low tide it is the opposite of high tide. When the water gate is opened, it is opened when the water level inside and outside the dam becomes the same. The two dams should be used separately. The amount of water in the dam is, for example, when the tidal tide level is 180 cm, and when the water measured inside the dam is used for power generation, the water level (head) on the outside and inside is increased. In order to make up for the water level (head) of the dam used at low tide to be 60 cm, power can be generated for 24 hours by using two dams as a set.

In a large dam, waste of water is eliminated by installing the present invention on the dam dam to discharge water for the downstream environment. In addition, since there is a large drop between the intake side and the drain side, large power generation is possible. Also, installation costs can be saved.

In the case of large, medium and small-scale hydroelectric power generation, the water level on the intake side and the water level on the drainage side can be selectively used as large, medium and small, which increases the number of installation sites for hydroelectric power generation, saves construction costs and eliminates wasted water.

When using the tidal range, two dams are built in the sea, and a sluice is installed. The sluice is closed at high tide, and the siphon is started when the tide level inside and outside the dam reaches about 60 cm. At low tide it is the opposite of high tide. By installing the hydropower start siphon type equipment, hydropower generation stable for 24 hours becomes possible.

When the present invention is used at sea, the water level on the drainage side in FIG. 5 rises and falls, so that the ship is floated on the drainage side and the present invention is installed on the ship.

Embodiments of the present invention will be described below.
I. This is illustrated in Figure 1. First, open each valve. First, close the intake valve at the intake port 8 under the tower where water is put. When the water in the tower is low, the outside water enters the tower. Second, close the 7 drain valve. Water is poured from the upper part of the tower into which water is put third or from the water injection valve 5A at the upper part of the water tank. Although not shown in the drawing, water is poured using a pump and a hose. When the tower into which water is filled is full, the 9C / 9D valve is closed, and water is injected from the water injection port of the water tank 5A fourth. When 4A and 4B tanks are full, both water injection valves and air vent valves are closed. 5th, water is poured from the 5B water inlet. When the tank is full, close the water injection valve and air vent valve. Open the 9C / 9D valve sixth. When the eighth intake valve is opened seventh and the seven drain valve is opened, water flows as shown by the arrow in FIG. 2 and the siphon is started.
B. The role of three water tanks in the upper part of Fig. 1. Prevent the water in the siphon from falling. Gases in water, air pools, and 3C siphon tubes in towers also prevent water from falling. The 3B / 3A siphon tube is larger than the 2A siphon tube. 9A, 9B and 9D are tightened when the air accumulated in the upper part of the upper tank is removed, and the 6-valve air vent is loosened and water is injected from the 5 valves.
