Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pumping apparatus capable of lifting water flowing down in a certain direction, such as water flowing through a river or a waterway, to a position higher than the water surface.

[0002]

2. Description of the Related Art As a means for pumping water flowing in a river or a water channel to a position higher than the water surface, a water wheel or a man-powered water wheel rotated by the flow of water has been used in the past. Various types of pumps that operate using power such as those described above have been developed, and are selectively used according to their applications.

[0003]

Water turbines and the like that have been used since the old days are convenient in that they operate without a driving means such as a motor, but construct a sturdy structure for supporting a rotating water turbine. It is necessary and once constructed, it cannot be easily moved or removed, so it cannot be easily adopted.

[0004] On the other hand, a pump operated by a motor or an engine cannot be operated without a power source or fuel, so that energy cost is required and it cannot be used in a place where there is no power supply equipment or where it is difficult to carry in fuel.

[0005] The problem to be solved by the present invention is to provide a water pumping apparatus which does not require a large-scale structure or the like, is relatively easy to install and move, and does not require a power source or a power source. .

[0006]

According to the present invention, there is provided a water pump having a water pipe immersed in water along a flowing direction of water flowing in a certain direction, and a water pipe standing upright communicating with a middle of the water pipe. A water pipe, the upstream end opening of the water pipe as a water inlet,
A first on-off valve having a function of closing the downstream end opening of the water pipe with the pressure of the water flowing into the water pipe from the water inlet is provided at the downstream end opening, and the pressure of the water rising in the water intake pipe is provided. A second on-off valve having a function of opening the intake pipe passage is provided in the water pipe, and the water pipe path downstream of the intake pipe standing position of the water pipe is formed so as to have an upward gradient toward the downstream side. It is characterized by the following.

[0007] With this configuration, if the water pipe is immersed in running water and a part of the downstream end opening is fixed so as to be exposed on the liquid surface, water can be passed through the water inlet at the upstream end. When the water flowing into the pipe fills the water pipe, the first on-off valve closes and stops the flow of water in the water pipe. At this moment, the kinetic energy of the water flowing down the water pipe causes the water to flow. Of the intake pipe rises in the intake pipe, opens the second on-off valve, and is discharged from the tip of the intake pipe. When the amount of water corresponding to the kinetic energy is discharged, the second on-off valve is immediately closed by the pressure of the water in the intake pipe above the second on-off valve. Since the amount of water in the water pipe decreases, the first on-off valve opens to restart the flow of water from the water inlet and start to accumulate in the water pipe, after which the above process is repeated.

[0008] As described above, the first on-off valve and the second on-off valve are alternately closed and opened by the pressure of the water flowing into the water pipe, whereby water is intermittently discharged from the tip of the water intake pipe. Therefore, it is possible to pump water without a power source or a power source. Further, since it is only necessary to immerse and fix the water pipe in running water, it is not necessary to construct a large-scale structure, and installation and movement are relatively easy. Here, the first on-off valve may adopt a structure that is pivotally supported below or above the downstream end opening of the water pipe so as to be tiltable.

If the inclination angle of the climbing slope is 10 to 30 degrees, the closing and opening operations of the first on-off valve by the water flowing into the water pipe can be smoothly performed.
Water is efficiently discharged from the intake pipe.

[0010] The longer the length from the water inlet to the intake pipe standing position, the higher the water can be raised to a higher position of the intake pipe. By making the length 4 to 60 times the length from the intake pipe standing position to the starting point of the ascending slope, it becomes possible to raise the water from the water surface near the water takeout to about 1 to 20 m, and Is improved. If the length ratio is less than 4 times, the water does not rise in the intake pipe, and if it is more than 60 times, it becomes difficult to secure the installation place of the water pipe itself, and the practicality is lost. The ratio is desirably in the above range.

[0011] Further, by making the inside diameter of the water pipe 4 to 45 times the inside diameter of the water intake pipe, it is possible to raise the water to about 1 to 20 m from the water surface near the water outlet. If the inside diameter of the water pipe is less than 4 times the inside diameter of the intake pipe, water does not rise in the intake pipe, and if it is larger than 45 times, the size or depth of rivers and waterways that can be installed is limited, making it impractical. Therefore, the inner diameter ratio is desirably in the above range.

Further, the tip of the intake pipe is connected to a water guide hole of an airtight water storage tank provided with a water guide hole higher than the drain hole, and a drain pipe having a tip drain port at a position higher than the water guide hole is drained. By connecting to the hole, the water flowing into the water storage tank from the intake pipe via the water introduction hole once becomes accumulated in the tank, and the accumulated water keeps the air pressure in the tank higher than the atmospheric pressure. Since the air pressure acts to push out the water in the tank, the water can be continuously discharged from the drain port of the drain pipe.

When the pressure is satisfied, the first on-off valve 16 is tilted downstream by the pressure of the water 11 to close the opening 15. The second on-off valve 18 is rotatably supported in the intake pipe 17 so as to be openable and closable, and normally closes the intake pipe 17 by its own weight. However, when a rising pressure is applied to the water 11 in the intake pipe 17, the The second on-off valve 18 rotates upward by the pressure of the water 11, and the water intake pipe 17 is opened.

As described above, if the water pipe 13 is immersed along the flow direction of the water channel 12 in which the water 11 flows in a certain direction and the upper part of the opening 15 at the downstream end is fixed in a state where the upper part is exposed from the water surface, As shown in FIG. 4, the water 11 flowing into the water pipe 13 from the water inlet 14 accumulates in the water pipe 13. At this time, the first on-off valve 1
6 is inclined to the upstream side and the opening 15 is in an open state, but the amount of water flowing into the water pipe 13 from the water inlet 14 is smaller than the opening 1.
Since the amount of water flowing out of the pipe 5 exceeds the amount, the water gradually accumulates in the water pipe 13.

When the inside of the water pipe 13 is filled with the water 11, as shown in FIG. 5, the first on-off valve 16 is closed by the water pressure and the movement of the water 11 flowing down the water pipe 13 is stopped. Due to the kinetic energy of the water 11 flowing down the water pipe 13, a part of the water 11 in the water pipe 13 rises in the water intake pipe 17 to open the second on-off valve 18, and the water intake pipe 1

Is opened, the flow of the water 11 from the water inlet 14 is restarted, and the water 11 accumulates in the water pipe 13. Thereafter, the process shown in FIGS. 4 and 5 is repeated.

As described above, the water 1 flowing into the water pipe 13
By alternately closing and opening the first on-off valve 16 and the second on-off valve 18 at the pressure of 1, the water 11 is intermittently discharged from the tip of the water intake pipe 17 and accumulated in the water storage tank 19, which will be described later. As described above, since an air pressure higher than the atmospheric pressure is generated in the water storage tank 19,
