[0005] Based on the above technical solution, the parallel grille is composed of a grille frame, a grille woven mesh, a woven mesh fixing frame, and an integrated fixing clamp. The grille woven mesh is arranged between the woven mesh fixing frame and the grille frame, and the grille woven mesh is fixed to the grille frame through the woven mesh fixing frame. The integrated fixing clamp is provided in several groups, and the several groups of integrated fixing clamps are respectively fixed on the sides of the grille frame, the grille woven mesh, and the woven mesh fixing frame.
[0006] On the basis of the above technical scheme, the grille frame is composed of a main frame, inserted rods, inserted tubes, and a convex clamp inner frame. The inserted rods and inserted tubes are arranged in parallel, and the inserted rods and inserted tubes are arranged on the upper and lower sides of the main frame. The convex clamp inner frame is arranged on one side of the inner side of the main frame, and a fixed frame embedding groove is arranged on the other side of the convex clamp inner frame. The side of the grille woven mesh is arranged in the fixed frame embedding groove on one side of the convex clamp inner frame, and the woven mesh fixing frame is arranged in the fixed frame embedding groove on one side of the convex clamp inner frame. The integrated fixing clamp is sleeved and fixed on the main frame, the convex clamp inner frame, the outer side of the woven mesh fixing frame and the side of the grille woven mesh. The inserted rods and inserted tubes in the two parallel groups of grille frames are inserted and docked with each other.
[0007] Based on the above technical solution, the integrated fixing clamp is made by bending a bent corner piece, and a docking notch is provided at the docking side end of the bent corner piece. The bent corner piece is covered on the main frame, the convex clamp inner frame, the outer side of the woven mesh fixing frame and the side of the grille woven mesh.
[0008] Compared with the prior art, the utility model has the following advantages: the utility model optimizes the setting of the trash rack, changes the structure and design of the traditional trash rack, and improves it into a trash rack that can be laterally moved and adjusted, with a wider range of applications. The structure adopts a split structure, which provides a more convenient method for damage maintenance and replacement of grille nets of different coarse and fine specifications, and is suitable for popularization and use.

DETAILED DESCRIPTION
[0015] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementations.
[0016] A trash rack for water conservancy projects comprises parallel grilles 1, wherein the parallel grilles 1 are provided in two groups, the two groups of parallel grilles 1 are staggered front and back, and the tops and bottoms of the two groups of parallel grilles 1 are connected to each other, and the two groups of parallel grilles 1 can be moved horizontally and adjusted left and right.
[0017] The parallel grille 1 is composed of a grille frame 2, a grille woven mesh 3, a woven mesh fixing frame 4, and an integrated fixing clamp 5. The grille woven mesh 3 is arranged between the woven mesh fixing frame 4 and the grille frame 2, and the grille woven mesh 3 is fixed to the grille frame 2 through the woven mesh fixing frame 4. The integrated fixing clamp 5 is provided in several groups, and the several groups of integrated fixing clamps 5 are respectively fixed to the sides of the grille frame 2, the grille woven mesh 3, and the woven mesh fixing frame 4.
[0018] The grid frame 2 is composed of a main frame 6, a pair of insertion rods 7, a pair of insertion tubes 8, and a convex clamp inner frame 9. The pair of insertion rods 7 and the pair of insertion tubes 8 are arranged in parallel, and the pair of insertion rods 7 and the pair of insertion tubes 8 are arranged on the upper and lower sides of the main frame 6. The convex clamp inner frame 9 is arranged on one side of the inner side of the main frame 6, and a fixed frame embedding groove 10 is arranged on the other side of the convex clamp inner frame 9. The side of the grid woven mesh 3 is arranged in the fixed frame embedding groove 10 on one side of the convex clamp inner frame 9, and the woven mesh fixing frame 4 is arranged in the fixed frame embedding groove 10 on one side of the convex clamp inner frame 9.
