[0027] Figure 4 This is a drainage system diagram of Example 2. DETAILED DESCRIPTION Example 1

[0028] like Figure 2 and Figure 3As shown, in this embodiment, the present invention includes an inner tube 1, the upper end of the inner tube 1 is provided with a sealing joint 2, and the lower end of the inner tube 1 is provided with a one-way water stop valve 3; in this embodiment, the inner tube 1 is a PVC tube, which is light in weight, low in cost, and has strong pressure resistance. The deep automatic drainage system also includes a drain pipe 4 and an air filling pipe 5. The lower end of the drain pipe 4 passes through the sealing joint 2 and extends into the interior of the inner tube 1. The upper end of the drain pipe 4 is a drain port. The lower end of the air filling pipe 5 passes through the sealing joint 2 and extends into the interior of the inner tube 1. The upper end of the air filling pipe 5 is connected to the air pump 6. The height of the lower end of the drain pipe 4 is lower than the height of the lower end of the air filling pipe 5. The lower ends of the drain pipe 4 and the lower ends of the air filling pipe 5 are both located between the sealing joint 2 and the one-way water stop valve 3. The one-way water stop valve 3 only allows external water to enter the inner tube 1 from the lower end of the inner tube 1, and prevents the water in the inner tube 1 from flowing out from the lower end of the inner tube 1. In this embodiment, the deep automatic drainage system also includes a water pool 11 connected to the upper end of the drain pipe 4. The water discharged from the drain pipe 4 is directly injected into the water pool 11. In this embodiment, as long as the water pressure in the drain pipe 4 is lower than the water pressure in the water pipe 12, the one-way water stop valve 3 can be opened, and the accumulated water 14 in the water pipe 12 can enter the inner tube 1 through the one-way water stop valve 3. When the air pump 6 inflates the inner tube 1, the water pressure at the bottom of the drain pipe 4 will be higher than the water pressure in the water pipe 12. The one-way water stop valve 3 is closed, which can prevent the accumulated water in the drain pipe 4 from flowing back into the water pipe 12 due to the increase in air pressure in the drain pipe 4, so that the accumulated water in the water pipe 12 can be continuously discharged.

[0029] In this embodiment, the water inlet end of the one-way water stop valve 3 is connected to a filter tube 7. Through the filter tube 7, debris in the accumulated water 14 can be filtered out to prevent the debris from getting stuck in the one-way water stop valve 3 and prevent the one-way function of the one-way water stop valve 3 from failing.

[0030] In this embodiment, a drain valve 8 is provided on the drain pipe 4. The drain valve 8 can control the on-off of the drain pipe 4, which can well meet the maintenance of the rear end pipeline of the drain pipe 4.

[0031] In this embodiment, an air inlet valve 9 is provided on the inflation pipe 5. The air inlet valve 9 can control the on-off of the inflation pipe 5, which can well meet the maintenance of the rear end pipeline of the inflation pipe 5.

[0032] In this embodiment, an automatic air valve 10 is further provided between the air inlet valve 9 and the air pump 6. Through the design of the automatic air valve 10, the function of automatic inflation and exhaust can be achieved, meeting different usage scenarios. Example 2

[0033] In this embodiment, the deep automatic drainage system described in the first embodiment is used, and the drainage method includes the following steps:

[0034] ① Insert the lower end of the inner tube 1 into the accumulated water 14 in the water pipe 12, and the accumulated water 14 enters the inner tube 1 through the one-way water stop valve 3;

[0035] ② When the water in the inner tube 1 and the accumulated water 14 in the water accumulation pipe 12 reach equilibrium, the air pump 6 is started, and the air pump 6 transports external air into the inner tube 1 through the inflation pipe 5;

[0036] ③ When the pressure of the inner tube 1 rises to a certain value, the water in the inner tube 1 is squeezed out by the high-pressure gas through the drain pipe 4;

[0037] ④ When a certain amount of water in the inner tube 1 is discharged and the liquid level in the inner tube 1 is lower than the lower end of the drain pipe 4, the air pump 6 stops working and the high-pressure gas in the inner tube 1 is discharged from the drain pipe 4;

[0038] ⑤ When the air pressure in the drainage pipe 4 drops to a certain pressure value, the accumulated water 14 enters the inner pipe 1 through the one-way water stop valve 3, and then enters step ②.

[0039] The present invention discharges the accumulated water 14 in the water pipe 12 by repeatedly pressurizing and releasing the pressure in the drainage pipe 4. The present invention can discharge the accumulated water 14 in the water pipe 12 to a depth of 100 meters. Example 3

[0040] like Figure 4As shown, the deep automatic drainage system also includes a sealing ring 13 that is sealed and connected to the upper end of the water accumulation pipe 12; the sealing ring 13 is sleeved on the inner tube 1, and there is accumulated water 14 in the water accumulation pipe 12. The lower end of the inner tube 1 is inserted into the accumulated water 14. At this time, a closed space 15 is formed between the outer wall of the upper part of the inner tube 1 and the inner wall of the upper part of the water accumulation pipe 12; the deep automatic drainage system also includes an air intake pipe 16, a first exhaust pipe 17 and a second exhaust pipe 18. The lower end of the air intake pipe 16 and the lower end of the first exhaust pipe 17 are both connected to the closed space 15 through the sealing ring 13. The air intake pipe 16, the first exhaust pipe 17 and the second exhaust pipe 18 are respectively provided with a first air valve 19, a second air valve 20 and a third air valve 21. The upper end of the air intake pipe 16 and the lower end of the second exhaust pipe 18 are both connected to the inflation pipe 5, and the upper end of the second exhaust pipe 18 is connected to the atmosphere. Through the structural design of this embodiment, the high-pressure gas in the inner tube 1 can be well utilized, avoiding the need to discharge the high-pressure gas in the inner tube 1 without use every time water is drained. When the accumulated water in the inner tube 1 is discharged to a certain amount, the high-pressure gas in the inner tube 1 is released into the water accumulation pipe 12, which can speed up the speed at which the accumulated water in the water accumulation pipe 12 enters the inner tube 1. Example 4

[0041] In this embodiment, the deep automatic drainage system described in the third embodiment is used, and the drainage method includes the following steps:

[0042] ① Insert the lower end of the inner tube 1 into the accumulated water 14 in the water pipe 12, open the drain valve 8, the air inlet valve 9, and the second air valve 20, and close the first air valve 19 and the third air valve 21. The accumulated water 14 enters the inner tube 1 through the one-way water stop valve 3;

[0043] ② When the water in the inner tube 1 and the accumulated water 14 in the water accumulation pipe 12 reach equilibrium, the air pump 6 is started, the automatic air valve 10 is opened, and the air pump 6 transports external air into the inner tube 1 through the inflation pipe 5;

[0044] ③ When the pressure of the inner tube 1 rises to a certain value, the water in the inner tube 1 is squeezed out by the high-pressure gas through the drain pipe 4;

[0045] ④ When a certain amount of water in the inner tube 1 is discharged and the liquid level in the inner tube 1 is lower than the lowermost end of the drain pipe 4, the air pump 6 stops working, the drain valve 8, the air inlet valve 9, the second air valve 20, and the third air valve 21 are closed, and the first air valve 19 is opened, and the high-pressure gas in the inner tube 1 enters the enclosed space 15 through the air inlet pipe 16. By allowing the high-pressure gas in the inner tube 1 to enter the enclosed space 15 through the air inlet pipe 16, the high-pressure gas in the inner tube 1 is effectively utilized instead of being discharged and released without use, thereby reducing energy waste and increasing the speed at which accumulated water enters the inner tube 1.

[0046] ⑤ When the air pressure in the enclosed space 15 and the air pressure in the inner tube 1 reach equilibrium, the first air valve 19 is closed and the third air valve 21 is opened. The high-pressure gas in the inner tube 1 is discharged through the second exhaust pipe 18, and at the same time, the accumulated water 14 enters the inner tube 1 through the one-way water stop valve 3. At this time, the interior of the inner tube 1 is connected to the atmosphere to achieve complete release of the air pressure in the inner tube 1, so that as much water as possible enters the inner tube 1.

[0047] ⑥ When the water in the inner tube 1 reaches equilibrium with the accumulated water 14 in the water collection pipe 12, the second air valve 20 is opened, the drain valve 8 and the air inlet valve 9 are opened, the third air valve 21 is closed, the air pump 6 is started, the automatic air valve 10 is opened, and the air pump 6 pumps outside air into the inner tube 1 through the air filling pipe 5, and then proceeds to step ③. The present invention discharges the accumulated water 14 in the water collection pipe 12 by repeatedly pressurizing and releasing the pressure in the drain pipe 4. This method can achieve discharge to a depth of 100 meters. At the same time, when the pressure in the drain pipe 4 is released, the high-pressure gas within it can be effectively utilized, which not only increases the discharge speed of the accumulated water but also saves energy.

[0048] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
