[0002] Trash grates are frame-type steel interception structures installed at the front end of water inlets in water conservancy projects. They consist of core components such as grates, diaphragms, and frames. The adjustable spacing of the grates effectively blocks debris such as driftwood and aquatic plants carried by the water flow, preventing them from entering the water turbine or water conveyance system and causing siltation.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1-3 As shown, a trash rack structure for water conservancy projects that is easy to install and disassemble includes a riverbank 1, a pre-embedded groove 2, a positioning hole 3, a trash rack 4, and positioning rods 5. Two pre-embedded grooves 2 are equally spaced on both sides of the riverbank 1. The positioning hole 3 is opened at the top of the pre-embedded groove 2. The trash rack 4 is fixedly connected between the two pre-embedded grooves 2 by two positioning rods 5 inserted into the positioning hole 3.

[0016] The trash rack 4 includes an outer shell 6, limiting side plates 7, a top cover 8, mounting screws 9, a cleaning device 10, traveling wheels 11, a stainless steel chain mesh 12, a linkage shaft limiting ring 13, a linkage shaft 14, a DC motor 15, a drive gear 16, a linkage gear positioning ring 17, a linkage gear 18, a drive shaft 19, and a gear cover 20. Two limiting side plates 7 are fixedly connected to both sides of the outer shell 6. The top cover 8 is bolted to the top of the outer shell 6 by four mounting screws 9. The cleaning device 10 is fixedly connected to the inner rear side of the outer shell 6. Stainless steel chain mesh 12 meshes with the outer sides of two sets of traveling wheels 11. Two linkage shaft limiting rings 13 are equidistantly fixedly connected to the outer shell 6. On the inner side below the outer casing 6, the linkage shaft 14 is fixedly connected between the two lower traveling wheels 11, and its two ends are slidably connected between the two linkage shaft limiting rings 13. The DC motor 15 is fixedly connected to the top right side of the top cover 8. The drive gear 16 is fixedly connected to the front end of the DC motor 15. The two linkage gear positioning rings 17 are respectively fixedly connected to the inner left side of the top cover 8 and the inner side below the outer casing 6. The linkage gear 18 is fixedly connected to the right side of the drive shaft 19 and is belt driven by the drive gear 16. The two ends of the drive shaft 19 are slidably connected between the two linkage gear positioning rings 17. The gear cover 20 is fixedly connected to the right side of the top cover 8.

[0017] The cleaning device 10 includes a baffle plate 21 and a drain slide 22. The baffle plate 21 is fixedly connected to the inner rear side of the outer casing 6, and the drain slide 22 is fixedly connected to the outer side of the baffle plate 21.

[0018] The working principle of this utility model is as follows: First, two pre-buried grooves and positioning holes are opened on both sides of the river channel. Then, the trash rack is snapped between the two pre-buried grooves. Two positioning rods are inserted between the limiting side plate and the positioning hole of the trash rack, fixing the trash rack in the river channel. Then, the DC motor is turned on, driving the drive gear to rotate, which in turn drives the linkage gear and linkage shaft to rotate, thereby rotating the outer traveling wheel. The traveling wheel drives the stainless steel chain mesh to circulate through meshing. When the debris intercepted on the surface of the stainless steel chain mesh reaches the top and rear of the stainless steel chain mesh, the debris is removed by the baffle plate and discharged to the bank through the sewage discharge chute. Then, manual cleaning is performed, completing the use of the device.

[0019] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
