[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment:

[0028] like Figure 1-7As shown, a water diversion tunnel structure for a water conservancy project comprises a tunnel body 1, a bottom plate 2 is slidingly fitted on the inner bottom wall of the tunnel body 1, and a plurality of mounting components 3 are provided on the upper end surface of the bottom plate 2 along the length direction of the tunnel body 1, wherein at least one mounting component 3 is located at the water outlet of the tunnel body 1; the mounting component 3 comprises a connecting plate 31 detachably connected to the bottom plate 2, and a plurality of vertical poles 32 are fixedly connected to the connecting plate 31 at equal intervals along the length direction of the connecting plate 31. In this embodiment, nine vertical poles 32 are provided, and the upper ends of the vertical poles 32 are fixedly connected to the mounting brackets 33. The shape of the mounting brackets 33 is adapted to the inner wall of the tunnel body 1. By providing the vertical poles 32, stones or plant branches carried by the water flow can be blocked, so that the tunnel structure can collect debris such as stones and branches; one side of the mounting bracket 33 is fixedly connected to There is a cleaning piece 4, which is located on the water-facing side of the mounting frame 33. The outer wall of the cleaning piece 4 is in contact with the inner wall of the tunnel body 1. The side of the cleaning piece 4 away from the mounting frame 33 is provided with a slope 41 to form a blade. The end of the base plate 2 is fixedly connected with multiple fixing rings 5. By using a chain (or connecting rope) to connect the fixing ring 5 to the transport vehicle (construction vehicle), the base plate 2 is pulled out of the tunnel body 1, and the silt accumulated on the base plate 2 and the stones and plant branches blocked by the vertical poles 32 are pulled out, which is convenient for workers to clean the base plate 2. In the process of pulling the base plate 2, the cleaning piece 4 scrapes and cleans the dirt on the inner wall of the tunnel body 1, and there is no need to manually enter the tunnel body 1 for cleaning. Since at least one mounting component 3 is located at the water outlet of the tunnel body 1, after the base plate 2 is pulled out as a whole, the entire tunnel body 1 can be cleaned.

[0029] like Figure 1-7 As shown, a plurality of lifting rings 6 are fixedly connected to the upper end surface of the base plate 2. The base plate 2 and the installation assembly 3 can be lifted until the lower end surface of the base plate 2 is flush with the bottom wall of the tunnel body 1 by cooperating with the lifting rope and the crane. The base plate 2 is pushed by a forklift so that the base plate 2 and the installation assembly 3 enter the tunnel body 1.

[0030] like Figure 1-7 As shown, the water inlet and the water outlet of the tunnel body 1 are fixedly connected with inclined blocks 7 , and the provision of the inclined blocks 7 helps to pull the bottom plate 2 out of the tunnel body 1 or push the bottom plate 2 into the tunnel body 1 .

[0031] like Figure 1-7 As shown, pressure plates 8 are fixedly connected to both sides of the inner wall of the tunnel body 1, and both sides of the bottom plate 2 slide between the lower end surface of the pressure plate 8 and the bottom wall of the tunnel body 1, making it more stable when pulling the bottom plate 2, and the lower ends of both sides of the mounting frame 33 and the lower ends of both sides of the cleaning piece 4 are fitted and slid on the pressure plate 8.

[0032] like Figure 1-7As shown, two connecting blocks 9 are fixedly connected to one side of the water inlet of the tunnel body 1. A fixing rod 10 extends through and slides through the two connecting blocks 9. A fixing ring 5 is located between the two connecting blocks 9, and the fixing rod 10 extends through the fixing ring 5. Second bolts 11 are detachably connected to both ends of the fixing rod 10. By simultaneously inserting the fixing rod 10 into the fixing ring 5 and the connecting blocks 9 and installing the second bolts 11, the bottom plate 2 can be prevented from sliding under the impact of the water flow. When the bottom plate 2 needs to be pulled out, the two second bolts 11 are removed and the fixing rod 10 is withdrawn, allowing the bottom plate 2 to be pulled out without restriction.

[0033] like Figure 1-7 As shown, support bars 12 are fixedly connected on both sides of the inner wall of the tunnel body 1, first bayonet holes 13 are provided on both sides of the mounting frame 33, and second bayonet holes 14 of the same size as the first bayonet holes 13 are provided on both sides of the cleaning piece 4. The bottom wall in the first bayonet hole 13 and the bottom wall in the second bayonet hole 14 are both in contact with the lower end surface of the support bar 12, and a groove 15 is provided on the upper wall of the first bayonet hole 13. A roller 16 is installed in the groove 15, and the roller 16 protrudes from the groove 15 and rolls on the support bar 12. By providing the roller 16, the mounting assembly 3 and the base plate 2 can move more smoothly in the tunnel body 1.

[0034] like Figure 1-7 As shown, a plurality of dividing strips 17 are fixedly connected to the bottom plate 2 at equal intervals. The provision of the dividing strips 17 helps to block the silt that sinks to the bottom of the water flow, so that the silt accumulates on the bottom plate 2. After the bottom plate 2 is pulled out, it is also convenient to clean the silt accumulated on the bottom plate 2.

[0035] like Figure 1-7 As shown, screw holes are provided on the bottom plate 2 , and the connecting plate 31 is detachably connected to the bottom plate 2 via first bolts 34 .

[0036] The working principle of a water diversion tunnel structure for a water conservancy project in this embodiment is: when it is necessary to clean the tunnel body 1, first remove the second bolt 11 and pull out the fixing rod 10, connect the fixing ring 5 to the transport vehicle by using a chain, pull the bottom plate 2 out of the tunnel body 1, and the silt accumulated on the bottom plate 2 and the stones and plant branches blocked by the vertical rods 32 are pulled out, making it easier for workers to clean the bottom plate 2. In the process of pulling the bottom plate 2, the cleaning piece 4 scrapes and cleans the dirt on the inner wall of the tunnel body 1, and there is no need to manually enter the tunnel body 1 for cleaning.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
