[0002] Trash racks can be arranged in a straight line or a semicircular broken line on the plane, and can be upright or inclined on the facade, depending on the nature, amount, application requirements and cleaning method of the dirt carried by the water flow. The height of the trash rack of a deep water inlet is related to the water level of the reservoir and the cleaning method. For those that do not require frequent cleaning, the elevation of its top can be slightly higher than the flood control limit water level (see reservoir characteristic value); for those that require frequent cleaning, it should be higher than the highest water level that requires cleaning. Trash racks with larger heights can be made into several sections, and the size of each section can be determined according to the lifting capacity. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals. Water conservancy projects are generally large in scale, require large investments, are technically complex, and have a long construction period.

The end face of the sliding block 32 is fixedly connected to the floating inclined plate 33, the upper end of the floating inclined plate 33 is fixedly connected to the fixing rope 34, the upper end of the fixing rope 34 is fixedly connected to the floating airbag 35, the movable cleaning component 4 includes a first mounting plate 41 and a first roller body 43, the end face of the first mounting plate 41 is fixedly connected to the floating inclined plate 33, the outer wall is fixedly connected to the first connecting shaft 42, the outer wall of the first roller body 43 is fixedly connected to the first push plate 44 and the first brush 45, and the outer wall of the first connecting shaft 42 is rotatably connected to the first roller body 43.

[0022] The utility model provides a water conservancy project garbage screen, which realizes the water level height and flow speed of the water flow in the river channel through the arrangement of the buoyancy component 3 and the movable cleaning component 4, so that the floating airbag 35 moves the floating inclined plate 33, thereby the garbage accumulated on the water surface enters the storage component 2 through the impact force of the water flow, and is collected to facilitate subsequent cleaning, while avoiding a large amount of garbage from accumulating on one side of the grid plate 103, reducing pollution, and the movable cleaning component 4 will move with the movement of the buoyancy component 3, and then through the arrangement of the fixed cleaning component 5, the first push plate 44 and the second push plate 55 are moved respectively by the flow force of the water flow, so that the first brush 45 and the second brush 54 clean the end face of the grid plate 103.

[0023] When the water level in the river is higher than the drainage hole 101, the garbage collected on the upper end of the floating inclined plate 33 will be carried into the storage assembly 2 by the impact of the water flow.

The second mounting plate 51 is fixedly connected to the fixed mounting frame 1, the end face of the second connecting shaft 52 is fixedly connected to the second mounting plate 51, and the outer wall is rotatably connected to the second roller body 53. The second brush 54 and the second push plate 55 are fixedly mounted on the outer wall of the second roller body 53. The second push plate 55 can be pushed by the force of water flow, so that the second roller body 53 drives the second brush 54 to rotate, thereby cleaning the end face of the grille plate 103 to avoid clogging by mud and stones.

[0028] like Figure 1 and Figure 3 As shown, as a preferred embodiment of the present invention, the first push plate 44 is fan-shaped and is divided into several groups, so that it is effectively pushed by the water flow. The number of the floating airbags 35 is two groups, and the floating inclined plate 33 is moved upward by the buoyancy of air and water flow. The size of the movable cleaning component 4 is the same as the length of the fixed cleaning component 5, so that it has a large cleaning range for the grid plate 103, which can keep the water flow in the river unobstructed.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
