Illustration of the principle that the liquid in the short pipe is pressurized by the gas space and the liquid in the long pipe and ejected to the outside The illustration of the fountain device in which the long pipe and the short pipe are divided by the common partition. When the long pipe is cylindrical and a plurality of short pipes are installed in parallel around the long pipe, the structure is highly efficient. Arrangement explanatory drawing of the pipe | tube 1 and the pipe | tube 2 of the cover part of a short tube.

In the present invention, three types of liquids, water-soluble liquids including water, water-insoluble oily liquids, and mercury, have been proposed as liquid column liquids. The usage form may be (1) a single component liquid (2) a mixed component liquid.
A mode for carrying out the invention will be described below for each case.

When a single component liquid is used and it is a water-soluble liquid, high specific gravity sodium tungstate is preferable. Water has many favorable points such as being inexpensive, having a track record as a water turbine, and having high safety. Disadvantages are that the specific gravity is as low as 1.0 and a high head is required, but it is preferable because stable operation can be expected. It is important to compensate for the weakness of low specific gravity by increasing the number of jets as much as possible.
Tungstic acid soda is used in the refining of specific gravity differences and is available in the market, and the specific gravity can be as high as about 3.1. Is possible. It is evaluated as high safety and is a preferable choice. Expensive points are alleviated by repeated circulation.

The oily liquid is preferably a fluorinated hydrocarbon-based liquid. Among these, varieties (C-HFC, such as ZEOLORA, specific gravity 1.58 manufactured by Nippon Zeon Co., Ltd.) used for cleaning electronic parts and the like are preferable.
Mercury has safety issues and is currently not preferred. When this problem is solved in the future, the specific gravity is large and a large output is expected, so I would like to continue research on safe usage. I want to avoid using it for the time being.

As an implementation procedure,
(1) The J-shaped tube can be made of plastic or metal. The most preferred liquids such as tungstate and fluorinated hydrocarbon liquids have already been used in fields such as specific gravity separation and cleaning, and the materials of the apparatus can be selected according to the results.
(2) The J-tube has a long long tube, and its height is experimentally determined from the required amount of jetted liquid in the short tube.
(3) The pipe 1 exiting from the upper part of the short pipe end is used for the fountain, and the pipe 2 is used for adjusting the distance between the gas space at the upper part of the short pipe end and the liquid level. When liquid is poured from the end of the long pipe, the liquid level in the long pipe and the short pipe rises at the same height when the on-off valve of the pipe 2 is open. When the distance between the end of the short pipe and the lid is about 10 cm, the open / close valve of the pipe 2 is closed and the liquid is continuously supplied to the long pipe side. The liquid is supplied until the liquid level of the liquid tank for the receiving liquid becomes approximately 5 cm. In this state, when the tube 1 is opened, the liquid starts to be ejected from the ejection port.
(4) A plurality of pipes 1 can be installed in parallel on the J-shaped short pipe to increase the liquid ejection point, thereby enhancing the rotation of the impeller. The number of installations is determined in consideration of the power generation situation.
(5) The jet height of the liquid rising from the short pipe via the pipe 1 is increased by the Bernoulli effect when the cross-sectional area of the jet outlet is smaller than the cross-sectional area of the continuous pipe 1. This is because the electric pump further increases the height of the fountain from the pipe 1 and achieves an effect of stabilization, and is preferably implemented by using solar power generation or self-power generation.
