[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 to Figure 3In an embodiment of the utility model, a filtering device for a water conservancy project includes a frame 1, which is a mouth-shaped structure. A plurality of vertically arranged filtering components are arranged on the inner side of the frame 1. The filtering component includes a limiting rod 5 fixedly connected to the bottom end of the inner wall of the frame 1, and an intercepting rod 2 is sleeved on the outer wall of the limiting rod 5. A fixing component connected to the limiting rod 5 is arranged on the top of the intercepting rod 2; the fixing component is used to fix the intercepting rod 2 sleeved on the outer wall of the limiting rod 5 to prevent the limiting rod 5 from moving up and down under the impact of water flow; the fixing component in a tightened state forms an effective downward pressure on the top of the intercepting rod 2; there is a channel for water circulation between adjacent intercepting rods 2, and the intercepting rod 2 is used to intercept and filter garbage.

[0022] In this embodiment: the trash rack is used as a filtering and intercepting device of a water conservancy project to intercept impurities such as garbage bags in a river. When the interception rod 2 is used for a long time and is severely damaged due to corrosion, the fixing assembly is rotated to cancel the limit of the filtering assembly. At this time, the interception rod 2 is pulled upward to separate from the outer wall of the limiting rod 5 until the interception rod 2 is completely pulled out. Then, a new interception rod 2 is reinserted. After insertion, the fixing assembly is rotated until the fixing assembly is completely tightened. The tightened fixing assembly presses the interception rod 2.

[0023] By means of the above method, the trash rack can be easily maintained.

[0024] Please refer to Figure 3 A limiting hole 7 is provided inside the limiting rod 5, and the top and bottom ends of the limiting hole 7 are both open structures.

[0025] In this embodiment: when inserting the intercepting rod 2, align the bottom of the limiting hole 7 with the top of the limiting rod 5, and then move the intercepting rod 2 downward, and the intercepting rod 2 slides downward along the outer wall of the limiting rod 5 until the bottom end of the intercepting rod 2 contacts the bottom end of the inner wall of the frame 1. The cooperation between the limiting hole 7 and the limiting rod 5 can realize the stable installation of the intercepting rod 2.

[0026] Please refer to Figure 3 The fixing component includes a docking hole 8 opened at the top of the limiting rod 5, the inner wall of the docking hole 8 is threadedly connected with a connecting column 9, the top of the connecting column 9 is fixedly connected with a connecting head 3, the outer circumference of the connecting head 3 is integrally formed with an external hexagonal block 4, the lower part of the outer wall of the connecting column 9 is formed with an external thread, and the inner wall of the docking hole 8 is formed with an internal thread, and the external thread is consistent with the internal thread.

[0027] In this embodiment: after the new intercepting rod 2 is connected to the limiting rod 5, the connecting column 9 is aligned with the connecting hole 8, and then a wrench is used to connect it to the external hexagonal block 4. The external hexagonal block 4 is subjected to force to drive the connecting head 3 to rotate, and the rotating connecting head 3 drives the connecting column 9 to rotate. At this time, the external thread on the outer wall of the connecting column 9 and the internal thread on the connecting hole 8 are engaged with each other, so the connecting column 9 moves downward while rotating until the internal thread and the external thread are fully engaged. At this time, the bottom end of the connecting head 3 effectively rests on the top of the intercepting rod 2, thereby ensuring that the bottom of the intercepting rod 2 is in full contact with the bottom end of the inner wall of the frame 1 to prevent an interception gap.

[0028] Please refer to Figure 3 The top of the limiting rod 5 is flush with the top of the inner wall of the frame 1 , and the outer wall of the limiting rod 5 and the inner wall of the limiting hole 7 are in a polygonal structure.

[0029] In this embodiment: the limit rod 5 is made of plastic material. After the intercepting rod 2 that needs to be replaced is removed, the thinner limit rod 5 bends under the flow of water. At this time, since the top height of the limit rod 5 is relatively high, the limit rod 5 can be straightened by hand to avoid the limit rod 5 being unable to dock with the intercepting rod 2 due to the impact of the water flow.

[0030] Please refer to Figure 3 A through slot 6 for inserting the intercepting rod 2 is provided on the top cross bar of the frame 1 , and the inner wall of the through slot 6 coincides with the outer wall of the intercepting rod 2 .

[0031] In this embodiment, the through slot 6 is used for the interception rod 2 to be inserted, so as to prevent the frame 1 from affecting the insertion of the interception rod 2 .

[0032] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
