The following description focuses on an example where N is 2, as shown in fig. 1:
1. first, the first stage tank 201 is filled with water, the "a 1" valve is closed, the "B1" valve is opened, the "C1" valve is opened,
since the uppermost water level inside the first-stage tank 201 is lower than the water surface of the lower reservoir, the water in the lower reservoir 100 fills the first-stage tank 201, and then the "B1" valve is closed, and the "C1" valve is closed.
2. The valve "A1" is opened, the first stage tank 201 is drained to release pressure, and the tank 201 is vacuumed. The second stage tank "E1" valve is then closed and the "D1" valve is opened. The second stage tank 301, which is in series with the first stage tank 201, receives the vacuum gravitational field from the tank 201 to form a negative pressure space.
The first stage "F1" valve is opened and the up flow pipe begins to draw water from the lower reservoir 100 into the second stage tank 301. Since the capacity and the vertical height of the drain of the first-stage tank 201 are greater than those of the second-stage tank 301, it is possible to ensure that the second-stage tank 301 is filled with water. Until the second stage tank 301 is filled with water, the water level continues to rise along the tank connection channel to a vertical level equilibrium with the tank drain level of 201, causing the flow of water to rest. When the upstream water line level is at rest, the "F1" valve is closed and water can be stored in the second stage tank 301. The first stage tank 201 is also stopped and the "D1" valve is closed and the "A1" valve is closed.
When the water level of the second-stage water tank 301 is higher than that of the upper reservoir 500, the valve H is opened, and water in the second-stage water tank 301 flows into the upper reservoir 500 under the action of gravity.
According to the schematic of figure 1, the principle of water column water level balance is applied, the water level of the first-stage water pumping mechanism is higher than that of the second-stage water pumping mechanism, and the high-level water drainage of the first-stage water tank necessarily pulls the low-level water supply of the second-stage water tank. The water stored at the high level is then released, thereby creating a vacuum in the tank discharge to the vacuum intake tank, creating a device configuration where water resources flow from the lower reservoir 100 up into the upper reservoir 500.
The following description focuses on an example where N is 3, as shown in fig. 2:
1. the third stage tank 401 is first filled with water for standby and then valves are actuated to fill the first stage tanks 201 and 202 with water for standby.
The valve "a 1" is closed, the valve "B1" is opened, the valve "C1" is opened, the water in the lower reservoir 100 fills the first stage tank 201 because the uppermost water level inside the first stage tank 201 is lower than the water level in the lower reservoir, and then the valve "B1" is closed and the valve "C1" is closed.
The "A2" valve is closed, the "B2" valve is opened, the "C2" valve is opened, the water in the lower reservoir 100 fills the first stage tank 202 because the uppermost water level inside the first stage tank 202 is below the water level in the lower reservoir, and then the "B2" valve is closed and the "C2" valve is closed.
2. The "a 1" valve is opened and the first stage tank 201 is drained to release pressure, creating a vacuum pull in the tank space. The "E1" valve was then closed, the "E2" valve was opened, and the "D1" valve was opened. At this time, the second-stage water tank 301 communicated with the first-stage water tank 201 receives the vacuum gravitational field effect of the tank 201 to form a negative pressure space.
The first-stage up-flow water pipe starts to suck water from the lower water reservoir 100 and flows upwards, the water level is lifted to the upper top position of the second-stage water tank and then falls into the second-stage water tank 301 until the second-stage water tank 301 is filled with water, the water level continues to rise along a connecting channel between the first-stage water tank 201 and the second-stage water tank 301 until the vertical height of the up-flow water level is balanced with the vertical height of the water discharge position of the first-stage water tank 201, and the water flow is static.
The top inverted V-shaped siphon also receives the action of the gravitational field of the first-stage water tank 201, starts to absorb water from the third-stage water tank 401, then enters the upper reservoir 500 along a siphon pipeline to form a siphon action until the water level of the groove at the bottom of the third-stage water tank 401 drops to be vertical to the water discharge level of the first-stage water tank 201 and is balanced, so that the water flow is static.
When the water level of the upstream water pipeline and the inverted V-shaped siphon pipeline is static, the water discharged by the 201 is static. The "D1" valve was then closed, and the "A1" valve was closed.
The valve "E1" is opened, atmospheric pressure enters the second-stage water tank 301, the water tank 301 returns to the normal state of atmospheric pressure, and the water level of the first-stage water supply pipeline instantly falls into the lower reservoir. Since the upper port of the water supply pipe extends to the top of the water tank, the water stored in the water tank does not fall down. Because the vertical height of the first-stage upstream pipeline is increased to extend into the lower water reservoir, sufficient water level sealing atmospheric pressure is still reserved in the first-stage upstream pipeline to enter the second-stage water tank 301, so that a negative pressure system of the water pumping mechanism can normally operate.
3. The "A2" valve was opened, the "E2" valve was closed, and the "D2" valve was opened. The third stage tank 401, now in series with the first stage tank 202, receives the vacuum gravitational field from the first stage tank 202 creating a negative pressure space.
The second stage up-flow pipe sucks water from the second stage water tank 301 and flows upwards, the water level is lifted to the upper top position of the third stage water tank 401 and then falls into the third stage water tank 401 until the third stage water tank 401 is filled with water, the water level continues to rise along the connecting channel between the first stage water tank 202 and the third stage water tank 401 until the vertical height of the up-flow water level is balanced with the vertical height of the 202 water tank drainage level, and the water flow is static.
After the third stage tank 401 is filled with water, the "D2" valve is closed, and the "A2" valve is closed.
The valve "E2" is opened, atmospheric pressure enters the third stage water tank 401, the water tank 401 returns to the normal state of atmospheric pressure, and the water level of the second stage water supply pipe instantly falls into the second stage water tank 301. Since the upper port of the water supply pipe extends to the top of the water tank, the water stored in the water tank does not fall down. Because the vertical height of the second-stage upstream pipeline is increased to extend into the second-stage water tank, sufficient water level sealing atmospheric pressure is still reserved in the second-stage upstream pipeline to enter the third-stage water tank 401, so that a negative pressure system of the water pumping mechanism can normally operate.
4. After the first stage tank 201 is drained, the "A1" valve is closed, then the "B1" valve is opened, and the "C1" valve is opened simultaneously, and after the first stage tank 201 is filled with water, the "B1" valve is closed, and the "C1" valve is closed.
5. The "A1" valve was reopened, the "D1" valve was opened, and the "E1" valve was closed. At this time, the second-stage tank 301 is on the water inlet, and the top-layer inverted V-shaped siphon sucks water from the third-stage tank 401 into the upper reservoir 500.
In this step, the process is repeated.
The case shown in fig. 2 is in principle similar to the case shown in fig. 1, and the upper end of the upper flow pipeline extends to the top position of the water tank, so that the water tank forms a one-way pipeline which only can feed water but can not discharge water. The lower port of the extension upstream pipeline extends into the reservoir and the groove of the water tank, so that the atmospheric pressure can be effectively isolated from entering the water tank. The water stored in the inverted V-shaped pipeline forms a water column with a certain height, and the water column can also seal atmospheric pressure and enter the water tank, so that the water tank keeps a negative pressure state. The structure saves the valve of an upstream pipeline and a top layer water tank drainage valve, adopts corrosion-resistant materials in the processing water tank and the pipeline, and is particularly suitable for pumping sewage.
