It is generally composed of flood diversion gates, channels and diversion tunnels. A diversion tunnel is a hydraulic tunnel that diverts water from a water source, usually located inside a mountain, and is used to transport water.

DETAILED DESCRIPTION

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments. Example 1

[0039] A cleaning irrigation mechanism is installed inside the tunnel body 1 and is located on one side of the filter 50. It is used to scrape the filter 50 and irrigate the surrounding vegetation.

The movable slider 13 is limitedly slidably connected to the inside of the mounting seat 6. A second slide groove 17 adapted to the sliding connection of the movable slider 13 is provided on the rotating disk 14. A first slide groove 16 adapted to the sliding connection of the driving slider 11 is also provided on the rotating disk 14.

[0040] Furthermore, the cleaning irrigation mechanism also includes a first rotating connecting rod 8 for connecting and driving the water flow to impact the first impeller 5. The first impeller 5 is rotatably mounted on the mounting seat 6 through the first rotating shaft 7. The first rotating connecting rod 8 is fixedly connected to the first rotating shaft 7. One end of the first rotating connecting rod 8 is rotatably mounted on the second rotating connecting rod 10 through the second rotating shaft 9. The movable slider 13 is limitedly slidably connected to the fixed slide 53, and the fixed slide 53 is fixedly mounted inside the mounting seat 6.

[0041] Furthermore, the cleaning irrigation mechanism also includes a piston plate 26 and an infusion cylinder 27 for driving the second cleaning brush plate 41 for cleaning connection control. The second cleaning brush plate 41 is rotatably connected to the first drain pipe 31 through the eighth rotating shaft 40. The first drain pipe 31 is connected to the interior of the infusion cylinder 27. The first drain pipe 31 is provided with a third control valve 32 for control. The infusion cylinder 27 is fixedly installed inside the mounting seat 6. The piston plate 26 is connected to the interior of the infusion cylinder 27 through a limited sliding connection of the piston rod 25. One end of the piston rod 25 is fixedly connected to one end of the movable slider 13. The infusion cylinder 27 is fixedly connected with a water inlet pipe 51, and a second one-way valve 52 is provided on the water inlet pipe 51.

[0042] Furthermore, the cleaning irrigation mechanism also includes a second impeller 35, a worm 38 and a worm wheel 39 for driving the second cleaning brush plate 41 to rotate and scrape. The second impeller 35 is rotatably installed inside the first drain pipe 31 through the seventh rotating shaft 36. The seventh rotating shaft 36 is rotatably connected to the worm 38 through the second synchronous belt 37. The worm 38 is meshed and connected to the worm wheel 39. The worm wheel 39 is fixedly connected to the eighth rotating shaft 40. The first drain pipe 31 is fixedly connected to the second drain pipe 33, and the second drain pipe 33 is provided with a first one-way valve 34.

[0043] Furthermore, the cleaning irrigation mechanism also includes an irrigation pipe 28 for irrigation connection, the irrigation pipe 28 is connected to the interior of the infusion tube 27, a second control valve 30 for control is provided on the irrigation pipe 28, and a plurality of nozzles 29 for vegetation spraying are also provided on the irrigation pipe 28, and the irrigation pipe 28 is fixedly installed on the outside of the tunnel body 1 through reinforcing ribs 49.

[0044] Furthermore, a sewage pipe 3 is fixedly connected to the bottom of the tunnel body 1 . The sewage pipe 3 is arranged on a side close to the filter screen 50 . A first control valve 4 is arranged on the sewage pipe 3 .

[0045] Preferably, the tunnel body 1 is guided by the water pipe 2 to conduct water diversion. The water guided by the water pipe 2 enters the interior of the tunnel body 1. Since the first impeller 5 is arranged on the side below the water pipe 2, the water entering continuously drives the first impeller 5 to rotate counterclockwise. Figure 6 to Figure 9 As shown, at this time, the first impeller 5 drives the first rotating link 8 on the first rotating shaft 7 to rotate continuously. Since one end of the second rotating link 10 is rotatably connected to the moving slider 13, under the traction and rotation of the second rotating shaft 9, the driving slider 11 on the second rotating link 10 is adapted to be slidably connected to the first sliding groove 16 on the rotating disk 14, and the moving slider 13 is adapted to be slidably connected to the second sliding groove 17 on the rotating disk 14. Specifically, when the driving slider 11 enters the interior of the first sliding groove 16, the second rotating link 10 pulls the moving slider 13 to move away from the rotating disk 14, and when the moving slider 13 moves toward the second sliding groove 17, the driving slider 11 moves away from the first sliding groove 16, thereby forming a periodic cycle, that is, the rotating disk 14 is driven to rotate clockwise, so that the moving slider 13 can be driven to move back and forth left and right and slide connected to the fixed slide seat 53.

[0046] When the movable slider 13 moves back and forth left and right, it correspondingly drives the piston plate 26 on the piston rod 25 to move back and forth and connect to the inside of the infusion cylinder 27. Since the second one-way valve 52 is provided on the water inlet pipe 51, the water in the tunnel body 1 enters the inside of the infusion cylinder 27 through the water inlet pipe 51, and the water in the infusion cylinder 27 will not be discharged from the water inlet pipe 51 in the reverse direction. At this time, by controlling the second control valve 30 to be closed and the third control valve 32 on the first drainage pipe 31 to be opened, the water in the infusion cylinder 27 enters the inside of the first drainage pipe 31 under the reciprocating push of the piston plate 26. When the water flow continues The second impeller 35 is driven to rotate under the continuous impact, and the worm 38 is driven to rotate under the synchronous driving action of the second synchronous belt 37, so that the second cleaning brush plate 41 on the eighth rotating shaft 40 is driven to rotate under the meshing connection between the worm 38 and the worm wheel 39. At this time, the water discharged from the first drain pipe 31 can be discharged from the second drain pipe 33 under the unidirectional action of the first one-way valve 34. This scraping method can well realize the cleaning operation on one side of the filter screen 50 in the tunnel body 1, avoid the blockage of the filter screen 50, and the impurities and sludge scraped off can be discharged through the sewage pipe 3 on the tunnel body 1.

[0047] This method utilizes the natural water flow power in the tunnel body 1, so that the second cleaning brush plate 41 can rotate with the water flow control and effectively clean one side of the filter screen 50. This automated cleaning method greatly reduces the frequency and labor intensity of manual cleaning, improves the cleaning efficiency, and keeps the filter screen 50 in good working condition at all times, thereby extending the service life of the filter screen 50, which not only reduces the frequency of replacing the filter screen 50, but also reduces maintenance costs.

[0048] Correspondingly, when it is necessary to irrigate the vegetation in the surrounding environment, the third control valve 32 on the first drainage pipe 31 is closed and the second control valve 30 on the irrigation pipe 28 is opened. At this time, the water in the infusion cylinder 27 can enter the irrigation pipe 28 and be discharged from the nozzle 29, thereby realizing the spraying operation of the vegetation in the surrounding environment, further improving the greening level of the surrounding environment. This method of irrigating vegetation through the flow of water in the tunnel body 1 greatly reduces the frequency and cost of manual irrigation, reduces the consumption of manpower and material resources, and also helps to realize the effective use of water resources and avoid waste of water resources.

[0049] It should be particularly noted that the seventh rotating shaft 36 and the worm 38 are both provided with pulleys which are synchronously connected with the second synchronous belt 37 . Example 2

[0050] like Figures 1 to 9As shown, based on Example 1, this embodiment further includes a wall cleaning mechanism, which is installed at the internal connection between the first impeller 5 and the mounting seat 6 and is connected to the cleaning irrigation mechanism. The cleaning irrigation mechanism drives the wall cleaning mechanism to clean the inner wall of the tunnel body 1 and the turbulence treatment in the tunnel body 1. The wall cleaning mechanism includes a first cleaning brush plate 24 for cleaning the wall and a turbulence drive blade 21. The turbulence drive blade 21 is rotatably mounted on the mounting seat 6 via a fifth rotating shaft 20.

[0051] Furthermore, the wall cleaning mechanism also includes a first gear 18 and a second gear 19 for driving the spoiler blade 21 and the first cleaning brush plate 24 for rotational connection control. The first gear 18 is fixedly connected to the fourth rotating shaft 15, and the first gear 18 is meshingly connected to the second gear 19. The diameter of the first gear 18 is larger than that of the second gear 19. The second gear 19 is fixedly connected to the fifth rotating shaft 20. The spoiler blade 21 is rotationally connected to the mounting seat 6 through the fifth rotating shaft 20, the first cleaning brush plate 24 is rotationally connected to the mounting seat 6 through the sixth rotating shaft 23, and the fifth rotating shaft 20 is rotationally connected to the sixth rotating shaft 23 through the first synchronous belt 22.

[0052] Preferably, in this embodiment, whenever the first impeller 5 rotates counterclockwise under the impact of the water flow, the rotating disk 14 is correspondingly driven to rotate clockwise intermittently, so that the rotating disk 14 drives the first gear 18 on the fourth rotating shaft 15 to rotate clockwise intermittently. Since the first gear 18 is meshedly connected to the second gear 19 and the diameter of the first gear 18 is larger than the second gear 19, the second gear 19 is driven to rotate counterclockwise intermittently and rapidly, which can correspondingly drive the spoiler blade 21 on the fifth rotating shaft 20 to rotate counterclockwise intermittently and rapidly, and the spoiler blade 21 on the fifth rotating shaft 20 is connected to the first rotating shaft 15. The impeller 5 maintains the same rotation direction, and due to the bending angle setting of the spoiler blade 21, the water flow in the tunnel body 1 can be driven toward the direction close to the filter screen 50 to perform the spoiler operation, further improving the speed of the water flow through the tunnel body 1, and the corresponding fifth rotating shaft 20 drives the first cleaning brush plate 24 on the sixth rotating shaft 23 to rotate under the synchronous driving action of the first synchronous belt 22, which can well realize the scraping operation of the inner wall of the tunnel body 1, avoid the accumulation of impurities and sludge on the inner wall of the tunnel body 1, and have a good cleaning effect.

[0053] This method utilizes the water flow power in the tunnel body 1 and the wall cleaning mechanism set up, so that the first cleaning brush plate 24 can rotate and clean naturally with the water flow. No additional power source is required to achieve the cleaning operation of the inner wall of the tunnel body 1. This automated cleaning method greatly improves the cleaning efficiency, reduces manual intervention, and reduces maintenance costs. At the same time, the spoiler blades 21 can guide and accelerate the flow of water, thereby optimizing the water flow path in the tunnel body 1, reducing water flow resistance, and thus significantly improving the water flow transportation efficiency. At the same time, the design of the spoiler blades 21 can not only accelerate the water flow, but also generate a certain scouring force on the inner wall of the tunnel body 1. This scouring force helps to remove sediment, dirt and impurities on the inner wall of the tunnel body 1, reduce the accumulation of sediment, thereby enhancing the self-cleaning ability in the tunnel body 1 and extending the service life of the tunnel body 1.

[0054] It should be particularly noted that both the fifth rotating shaft 20 and the sixth rotating shaft 23 are provided with pulleys which are synchronously connected with the first synchronous belt 22 . Example 3

[0055] like Figures 1 to 12 As shown, this embodiment, based on the above embodiment, further includes a water flow reduction mechanism, which is installed inside the tunnel body 1 and is used to buffer and reduce the impact of the water flow.

[0056] Furthermore, the water flow reduction mechanism includes a buffer cone 42 and a buffer spring 46 for water flow buffering connection. The buffer cone 42 is connected to the arch support frame 43 and the guide cylinder 45 by a connecting slide rod 44 through limited sliding. The guide cylinder 45 is fixedly connected to the arch baffle frame 47. The arch support frame 43 and the arch baffle frame 47 are both fixedly installed inside the tunnel body 1. A buffer spring 46 is provided at the internal connection between the connecting slide rod 44 and the guide cylinder 45. A plurality of dredging grooves 48 are opened on the arch baffle frame 47.

[0057] Preferably, in this embodiment, the water flow discharged from the tunnel body 1 is guided and buffered under the conical action of the buffer cone 42, and the connecting slide rod 44 is driven to move and connect to the guide cylinder 45 under the impact of the water flow, so that the water flow is reduced under the buffering action of the buffer spring 46, avoiding collapse or damage in the tunnel body 1 caused by excessive water accumulation, thereby effectively reducing the direct impact of the water flow on the wall of the tunnel body 1, reducing the erosion and damage in the tunnel body 1 caused by water flow scouring, thereby extending the service life of the tunnel body 1 and enhancing the overall stability and safety of the structure.

[0058] It should be particularly noted that the components in this application are all universal standard parts or components well known to those skilled in the art, which effectively solve the technical problems raised in the background technology.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
