For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Example 1

[0028] like Figure 1-5 As shown, a tunnel drainage pipe includes a drainage pipe body 4, a one-way valve 18 is arranged on the top of the drainage pipe body 4, the one-way valve 18 is fixedly connected to the drainage pipe body 1, the one-way valve 18 is connected to the lower end of the water storage pipe 6, a rainwater storage tank 17 is arranged above the water storage pipe 6, the upper end of the water storage pipe 6 passes through the bottom of the rainwater storage tank 17 and extends into the rainwater storage tank 17, the water storage pipe 6 is fixedly connected to the rainwater storage tank 17, a first piston 26 is arranged in the water storage pipe 6, and the first piston 26 is connected to the water storage pipe 6 The inner wall is slidably connected, the first piston 26 is fixedly connected to the lower end of the first connecting rod 10, the upper end of the first connecting rod 10 is fixedly connected to the bottom of the second piston 16, the second piston 16 is located in the rainwater storage tank 17, the second piston 16 is slidably connected to the inner wall of the rainwater storage tank 17, a plurality of seepage pipes 9 are penetrated by the second piston 16, the seepage pipes 9 are fixedly connected to the second piston 16, and a driving mechanism is installed on the rainwater storage tank 17, the driving mechanism is used to drive the second piston 16 to reciprocate up and down.

[0029] The drainage pipe body 4 is buried in the water diversion tunnel, the rainwater storage box 17 is buried in the soil, and the cover plate 3 is exposed on the ground. When it rains, rainwater flows into the rainwater storage box 17 through the seepage holes 2 on the cover plate 3, and then flows to the bottom of the rainwater storage box 17 through the seepage pipe 9. When the driving mechanism drives the second piston 16 to move upward, the second piston 16 drives the first piston 26 to move upward synchronously through the first connecting rod 10. When the first piston 26 moves to above the water inlet pipe 12, the rainwater at the bottom of the rainwater storage box 17 enters the water storage pipe 6 through the water inlet pipe 12.

[0030] When the driving mechanism drives the second piston 16 to move downward, the second piston 16 drives the first piston 26 to move downward synchronously through the first connecting rod 10, so that the first piston 26 pushes the water in the water storage pipe 6 into the drainage pipe body 4 through the one-way valve 18. Due to the setting of the one-way valve 18, the water in the drainage pipe body 4 cannot flow back into the water storage pipe 6.

[0031] In this way, the rainwater continuously enters the water storage pipe 6, and the first piston 26 continuously pushes the water in the water storage pipe 6 into the drainage pipe body 4 through the one-way valve 18, thereby effectively increasing the water diversion volume during the water source transfer process.

[0032] Example 2

[0033] like Figure 1-5 As shown, when other parts are the same as those of Example 1, the difference between this embodiment and Example 1 is that: a cover plate 3 is provided above the rainwater storage box 17, and a plurality of seepage holes 2 are provided in the center of the cover plate 3. A top cover 11 is sleeved on the first connecting rod 10, and the top cover 11 is slidably matched with the first connecting rod 10, and the top cover 11 is fixedly connected to the top of the water storage pipe 6. A plurality of water inlet pipes 12 are provided through the top of the water storage pipe 6, and the water inlet pipes 12 are fixedly connected to the water storage pipe 6. The driving mechanism includes a second connecting rod 15, the upper end of the second connecting rod 15 is fixedly connected to the bottom of the second piston 16, the lower end of the second connecting rod 15 is fixedly connected to the slider 13, the slider 13 is connected to the reciprocating screw 5, the slider 13 is against the inner wall of the rainwater storage box 17, the reciprocating screw 5 passes through the bottom of the rainwater storage box 17, and the lower end of the reciprocating screw 5 is connected to the driving assembly, and the driving assembly is used to drive the reciprocating screw 5 to rotate in one direction. A limit block 14 is arranged above the reciprocating screw rod 5 , and the top end of the reciprocating screw rod 5 is fixedly connected to the limit block 14 .

[0034] The driving assembly includes a fixed tube 24, which passes through the top of the drainage tube body 4 and is fixedly connected to the drainage tube body 4. A sealing groove 23 is provided on the inner wall of the fixed tube 24, and a sealing ring 22 is provided in the sealing groove 23. The sealing ring 22 is fixedly sleeved on the third piston 19. The third piston 19 is located in the fixed tube 24, and the third piston 19 is fixedly sleeved on the third connecting rod 25. The upper end of the third connecting rod 25 is fixedly connected to the lower end of the reciprocating screw rod 5, and the lower end of the third connecting rod 25 extends into the drainage tube body 4. The lower end of the third connecting rod 25 is sleeved with a one-way bearing 21, the inner ring of the one-way bearing 21 is fixedly connected to the reciprocating screw rod 5, and the outer ring of the one-way bearing 21 is fixedly connected to the spoiler 20.

[0035] When water flows in the drainage tube body 4, the spoiler 20 is driven to swing back and forth. Due to the setting of the one-way bearing 21, when the spoiler 20 swings clockwise, the spoiler 20 will not drive the third connecting rod 25 to rotate synchronously. When the spoiler 20 swings counterclockwise, the spoiler 20 will drive the third connecting rod 25 to rotate synchronously. Therefore, the third connecting rod 25 continues to rotate unidirectionally, and the third connecting rod 25 drives the reciprocating screw rod 5 to rotate unidirectionally. The reciprocating screw rod 5 drives the slider 13 to move back and forth up and down, and the slider 13 drives the second connecting rod 15 to move back and forth up and down. The second connecting rod 15 drives the second piston 16 to move back and forth up and down. The second piston 16 drives the first piston 26 to move back and forth up and down through the first connecting rod 10, so that the first piston 26 can automatically move back and forth up and down without power.

[0036] Example 3

[0037] like Figure 1-5 As shown, when other parts are the same as those of Example 2, the difference between this embodiment and Example 2 is that: a sign rod 1 is provided through the cover plate 3, the sign rod 1 and the cover plate 3 are slidably matched, and the lower end of the sign rod 1 is fixedly connected to the second piston 16. A limit plate 8 is sleeved on the sign rod 1, the limit plate 8 is fixedly connected to the sign rod 1, a limit screw 7 is threadedly connected to the limit plate 8, and a threaded hole matching the limit screw 7 is opened on the cover plate 3.

[0038] When the second piston 16 reciprocates up and down, the second piston 16 drives the marking rod 1 to reciprocate up and down. By observing whether the marking rod 1 moves, it can be known whether the device is running.

[0039] When the marker rod 1 moves downward, the limit plate 8 is driven to move downward synchronously. When the limit plate 8 is close to the cover plate 3, the limit screw 7 is connected to the limit plate 8 and the threaded holes on the cover plate 3 at the same time, so that the marker rod 1 can no longer move, so that the first piston 26 no longer moves up and down to push rainwater into the drainage pipe body 4.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
