The vacuum device 7 can be a vacuum pump or a vacuum station, and can be matched with a single or multiple sets of water pumping devices; The outer mouth of the open check valve 2 is equipped with a bottom-inserted suction pipe 10, which is inserted into the water to be pumped, and the outer mouth of the lower open check valve 3 is equipped with a discharge pipe 9 leading to a container 12 for pumping water. Middle; the floating body of the floating air pressure regulating device 6 is located in the sealed pressure regulating water tank 1, and the floating body can move up and down under the buoyancy of water, and through the linkage mechanism, the sealed pressure regulating water tank 1 Connected or disconnected to external atmospheric pressure.

As shown in Figure 2, the floating air pressure regulating device 6 is a floating ejector rod structure, the floating body is a float 14, and a ejector rod 15 is installed on it, and a ventilating cylinder 16 which doubles as a positioning slideway for the ejector rod 15 is installed in a sealed type. On the pressure regulating water tank 1, the valve plate 18 with the top 17 and the supporting valve seat 19 are installed in the ventilating cylinder 16, the top 17 is matched with the ejector rod 15, and there is a gasket 20 between the valve plate 18 and the valve seat 19. 18 has a pressure regulating spring 23 that is compressed by a gland 21 that is mounted on the top of the vent tube 16 and has a vent hole 22 .

As shown in Figure 3, the floating air pressure regulating device is a floating ball valve structure, the floating body is a floating ball 24, and a crank arm 25 is mounted on it, and the crank arm is hinged with a pin shaft 26 installed in the sealed pressure regulating water tank 1. Together, the other end of the crank arm 25 is hinged together with the valve rod 29 of the intake valve 28 through the small shaft 27, and the valve 28 is contained in the sealed pressure regulating water tank 1, and has a matching intake pipe 30 to communicate with the atmosphere.

As shown in Figure 1, the height to which the water is lifted is related to the degree of vacuum in the sealed pressure regulating water tank 1. In general, when the maximum effective water storage capacity in the sealed pressure regulating water tank 1 is ensured, its The height H1 between the highest point of the water surface and the bottom opening of the water suction pipe 10 is the height at which the water is lifted, which is generally 3-8m.

Brief description of the working principle:

Before vacuuming in the pressure regulating water tank 1, the upper opening check valve 2, the lower opening check valve 3, and the valve plate 18 (or valve 28) are in a closed state, and the floating body float 14 ( Or the floating ball 24) is in the free lowest position; after the vacuum pumping device 7 is started, the sealed pressure regulating water tank 1 is vacuumed, and with the increase of the vacuum degree, the upper opening check valve 2 is gradually opened in place, and is pumped at the same time The water body rises from the storage tank 12 through the bottom-type suction pipe 10 and enters the sealed pressure-regulating water tank 1. The water level in the tank rises gradually, and pushes the float 14 (or float 24) to rise, thereby opening it through the linkage mechanism. The valve plate 18 (or valve 28) connects the inside of the sealed pressure-regulating water tank 1 with the external atmospheric pressure, and the water in the tank automatically opens the bottom-opening check valve 3 by means of potential energy under the action of the atmospheric pressure, and It flows into the container 11 through the discharge pipe 9. When the sealed pressure-regulating water tank 1 is connected to the atmospheric pressure, the upper-opening check valve 2 is immediately closed under the action of gravity and water level energy, and the water will not return to the original path. ; Along with the decline of the water level in the sealed pressure regulating water tank 1, the float 14 (or float 24) gradually descends to the position, and the corresponding valve plate 18 (or valve 28) returns to the position and closes thereupon, so that the sealed pressure regulating The inside of the water tank 1 is disconnected from the external atmospheric pressure, and at the same time, the bottom-opening check valve 3 automatically returns to its position and closes, and the vacuuming continues, and then repeatedly absorbs and discharges water, and so on, realizing intermittent pumping. Multiple sets of pumping devices can be connected in parallel to achieve integral continuous pumping, and increase the pumping volume and pumping speed; when multiple sets of pumping devices are connected in parallel and share a set of vacuum device 7, the connection pipe 8 in each set of devices needs to be installed An automatic control valve interlocked with the water pumping process of this set of devices.

As a result of the test, it was completely successful, and the water was successfully extracted to a height of more than 5m.

The device can pump water from one place to another, especially for increasing the potential energy of water (theoretically, it can be raised 10 meters high at a time), which is of special significance for the development of independent self-circulating power stations with water. offers realistic possibilities.
