[0020] 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.

[0021] See also Figures 1 to 4 In an embodiment of the utility model, a trash rack for a water conservancy project includes a connecting pier 1. The connecting pier 1 is a "C"-shaped structure with an open top. The inner wall of the connecting pier 1 is detachably connected to a main trash rack mechanism, and the end face of the connecting pier 1 close to the water inlet direction is detachably connected to a temporary trash rack mechanism; the temporary trash rack mechanism and the main trash rack mechanism are used alternately to prevent the main trash rack mechanism from flowing downward when the main trash rack mechanism is replaced; the main trash rack mechanism and the connecting pier 1 are slidably connected to the sliding block 6 through the guide groove 5, and the temporary trash rack mechanism and the connecting pier 1 are slidably connected to the guide plate 7 through the guide rail 3, and the bottom end of the guide plate 7 is a closed structure.

[0022] In this embodiment: first, the connecting pier 1 is installed in the water conservancy waterway, and then the main trash rack mechanism is inserted into the connecting pier 1 from above the connecting pier 1 until the main trash rack mechanism and the connecting pier 1 are installed. After that, the dirt in the water conservancy waterway can be intercepted. After the main trash rack mechanism is damaged, the temporary trash rack mechanism is installed first. After the temporary trash rack mechanism is installed, the main trash rack mechanism is taken out from the connecting pier 1, and the main trash rack mechanism can be replaced. The main trash rack mechanism and the temporary trash rack mechanism used at staggered times can be used in conjunction to avoid the flow of dirt downstream when the main trash rack is replaced.

[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The main trash rack mechanism includes a circular plate 2 integrally formed between two sliding blocks 6. The circular plate 2 is a hollow circular structure. The circular plate 2 is equidistantly welded with vertically arranged main trash grilles 8 near the water inlet direction. The guide grooves 5 are opened on both sides of the inner wall of the vertical plate portion connecting the pier 1. The two sliding blocks 6 are respectively slidably connected to the inner walls of the two guide grooves 5, and the two sliding blocks 6 are fixedly connected to the main trash rack mechanism.

[0024] In this embodiment: first, the sliding block 6 is aligned with the guide groove 5, and the return plate 2 is lowered. The return plate 2 drives the sliding block 6 to move downward along the guide groove 5 under gravity until the bottom end of the return plate 2 contacts the bottom end of the inner wall of the connecting pier 1. At this time, the flowing water flows between the adjacent main trash screens 8, and the dirt is intercepted by the main trash screens 8. The dirt accumulates at the front end of the main trash screen 8 and can be cleaned regularly afterwards.

[0025] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The temporary trash rack mechanism includes a horizontal plate 4 arranged horizontally. There are multiple horizontal plates 4, and the multiple horizontal plates 4 are equidistantly arranged in the vertical direction. Multiple fixing rods 9 are welded at equal intervals on the end of the horizontal plate 4 away from the water inlet. The two fixing rods 9 located at the head and tail of the horizontal plate 4 are welded to one end of the guide plate 7. One end of the other multiple fixing rods 9 located at the non-head and tail of the horizontal plate 4 is welded with a temporary trash rack 10. The temporary trash rack 10 and the main trash rack 8 are staggered with each other. The guide rail 3 is fixedly connected to one end face of the connecting pier 1. The two guide plates 7 are respectively slid up and down and connected to the inner walls of the two guide rails 3. The guide plate 7 is fixedly connected to the temporary trash rack mechanism.

[0026] In this embodiment, when the main trash rack 8 becomes rusty or broken after long-term use, and the trash cannot be effectively intercepted, the guide plate 7 and the guide rail 3 are aligned in the vertical direction, and then the temporary trash rack 10 is lowered. The temporary trash rack 10 can effectively intercept the trash, and the main trash rack mechanism can be taken out and replaced.

[0027] It should be noted that when the main trash rack mechanism is in use and the temporary trash rack mechanism is not in use, a rubber plug that matches the inner wall of the guide rail 3 can be inserted into the inner wall of the guide rail 3 to prevent impurities from clogging the inner wall of the guide rail 3 and preventing the temporary trash rack mechanism from being installed smoothly.

[0028] Please refer to Figure 3 and Figure 4 A support plate 11 is welded to one end of the return plate 2 away from the water inlet direction. The support plate 11 is arranged in a horizontal state, and there are multiple support plates 11, which are vertically equidistantly distributed on the return plate 2.

[0029] In this embodiment, the provision of the support plate 11 can provide effective support to the back end of the main trash screen 8 , thereby improving the deformation resistance of the main trash screen 8 .

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
