The support frame 5 is made of reinforced cement concrete.

[0032] Specifically, each water absorption system includes a water absorption tank unit, a water pool connecting pipe 11 at the top of the mountain and the foot of the mountain, a spiral pipe 12, and a water inlet pipe 14 at the top of the mountain for connecting a water source. The water absorption tank unit includes a water absorption tank 1 at the foot of the mountain 6, a water absorption tank 2 at the foot of the mountain 7, a water absorption tank 1 at the top of the mountain 8, a water absorption tank 2 at the top of the mountain 9, and a water absorption tank 3 at the top of the mountain 10. The water absorption tank 1 at the foot of the mountain 6, the water absorption tank 2 at the foot of the mountain 7, the water absorption tank 1 at the top of the mountain 8, the water absorption tank 2 at the top of the mountain 9, and the water absorption tank 3 at the top of the mountain 10 include a tank body A, a water inlet B, a water outlet C, and an exhaust valve 2C. The water inlet B and the exhaust valve 2C are respectively arranged at the top of the tank body A, and the water outlet C is arranged at the bottom of the tank body A. The function of the exhaust valve 2C is to exhaust the air in the tank body A.

[0033] The foot of the mountain water absorption tank 1 6 and the foot of the mountain water absorption tank 2 7 are respectively arranged in the machine room 2, the top of the mountain water absorption tank 3 10 is arranged on the top of the mountain and is located next to the top of the mountain water pool 3, and the top of the mountain water absorption tank 1 8 and the top of the mountain water absorption tank 2 9 are respectively arranged on the support frame 5, the support frame 5 includes a support column 501, a support plate 502 and a top plate 503, the support column 501 is installed on the top of the mountain, and the support plate 502 is installed in the middle of the support column 501, so that the support plate 502 and the top of the mountain form a first floor, and the support plate 502 and the top of the mountain form a second floor. The top of the mountain water absorption tank 1 8 and the top of the mountain water absorption tank 2 9 are respectively arranged on the support plate 502, that is, the top of the mountain water absorption tank 3 10 is placed on the first floor, and the top of the mountain water absorption tank 1 8 and the top of the mountain water absorption tank 2 9 are respectively placed on the second floor, so that the installation positions of the top of the mountain water absorption tank 1 8 and the top of the mountain water absorption tank 2 9 are higher than the installation position of the top of the mountain water absorption tank 3 10, thereby forming a potential energy difference of water, which is conducive to discharging water into the top of the mountain water pool 3. The top plate 503 is installed on the top of the support column 501. The water inlet end of the mountain top foot pool connecting pipe 11 and the mountain top water inlet pipe 14 are respectively installed with a water inlet valve 15, the water outlet of the mountain top water suction tank 3 10 and the mountain top pool drain pipe 13 are respectively installed with a drain valve 16, and the water inlet end of the mountain top water suction tank 2 9 is installed with an exhaust valve 17. The water inlet end of the mountain top pool drain pipe 13 shrinks toward the water outlet end to form a trumpet shape, the purpose of which is that the large diameter of the water inlet end of the mountain top pool drain pipe 13 can reduce the suction resistance, and the small diameter of the water outlet end of the mountain top pool drain pipe 13 is conducive to maintaining the pressure of the water outlet, thereby achieving the balance of water supply. From a technical point of view, the shrinkage of the water inlet end of the mountain top pool drain pipe 13 toward the water outlet end can control the water flow speed to avoid deposition and excessive wear.

[0034] like Figure 1 and Figure 2 As shown, the water pool connecting pipe 11 at the top of the mountain and the foot of the mountain is laid out from the foot of the mountain to the top of the mountain in a serpentine manner. Figure 3 and Figure 4As shown, the water pool connecting pipe 11 at the top of the mountain and the foot of the mountain is laid in a spiral pipe manner from the foot of the mountain to the top of the mountain. The water inlet end of the mountain top and foot pool connecting pipe 11 is connected to the foot pool 2, the water outlet end of the mountain top and foot pool connecting pipe 11 and the mountain top water inlet pipe 14 are respectively connected to the water inlet of the mountain top water suction tank 8, the water outlet of the mountain top water suction tank 8 is connected to the water inlet of the foot mountain water suction tank 6, the water outlet of the foot mountain water suction tank 6 is connected to the water inlet of the foot mountain water suction tank 7, the water outlet of the foot mountain water suction tank 27 is connected to the water inlet of the mountain top water suction tank 29, the water outlet of the foot mountain water suction tank 29 is connected to one end of the spiral tube 12, the other end of the spiral tube 12 is coiled downward along the support frame 5 and connected to the water inlet of the mountain top water suction tank 3 10, the water outlet of the mountain top water suction tank 3 10 is connected to the mountain top water pool 3, the water inlet end of the mountain top water pool drain pipe 13 is connected to the bottom of the mountain top water pool 3, the water outlet end of the mountain top water pool drain pipe 13 is connected to the water inlet of the hydro-turbine generator 4, and the water outlet of the hydro-turbine generator 4 is connected to the foot pool 2. The water inlet end of the mountain top and foot pool connecting pipe 11 of each water absorption system is respectively connected to the mountain foot pool 2, and the water outlet of the mountain top water absorption tank 3 10 of each water absorption system is respectively connected to the mountain top pool 3.

[0035] The connection between the top water suction tank 18, the top water suction tank 29, the foot water suction tank 16 and the top water suction tank 27 is to increase the dynamic compression energy storage, and to create a starting water flow by sucking in or other means by connecting the water pump through the top water inlet pipe 14. Open the exhaust valve 2C of the top water suction tank 18, the top water suction tank 29, the top water suction tank 3 10, the foot water suction tank 16 and the top water suction tank 26, open the water inlet end of the top foot water pool connecting pipe 11 and the water inlet valve 15 on the top water inlet pipe 14, and the water outlet of the top water suction tank 3 10 and the top water pool drainage pipe 1 3, the exhaust valve 17 at the water inlet end of the top water suction tank 2 9, fill the water tank with water to the water suction system, the foot water pool 2, the top water pool 3, the top water pool drainage pipe 13 and the turbine 401, and connect the top water suction tank 1 8, the top water suction tank 2 9, the foot water suction tank 1 6 and the top water suction tank 2 7 to make the water of the foot water pool 2 and the top water pool 3 reach the effect of upper and lower water gravity balance, and use the effect of upper and lower water gravity balance to realize water circulation between the water suction system, the foot water pool 2, the top water pool 3, the top water pool drainage pipe 13 and the turbine 401. The water in the pipe of the water suction system begins to drop, not because of gravity pulling it down, but because a vacuum effect is formed in the pipe of the water suction system when the water drops. This vacuum effect reduces the air pressure inside the pipe of the water suction system, so that the atmospheric pressure pushes the water to continue to move upward. The function of the top water suction tank 3 10 is to discharge water to the top water pool 3 through the spiral pipe 12. The function of the exhaust valve 17 of the mountain top water suction tank 10 is to further exhaust the air in the water suction system pipe body.

The water in the foot pool 2 can be sucked into the top pool 3 by opening the drain valve 15 at the outlet of the top pool 3, and the water discharged from the drain pipe 13 of the top pool drives the turbine 401 to rotate, the turbine 401 drives the flywheel 409 to rotate, and the flywheel 409 drives the generator 411 to rotate to generate electric energy.
