[0002] Water transfer channels are important hydraulic structures for transferring water resources. However, existing water transfer channels generally cannot guarantee the cleanliness of the water being transferred. Plastic products, concrete fragments and other solid waste are usually transferred with the water. Such solid waste not only affects the cleanliness of the water, but also accumulates at some nodes in the water transfer project, affecting the normal operation of the water transfer project. Therefore, a pollution interception device is needed to intercept the solid waste in the water transfer channel to purify the water and improve the stability of water transfer.

[0003] The existing water channel trash interception device usually uses a perforated trash rack inserted into the water body to achieve the trash interception function, but such a device is generally designed with only one layer of perforated trash rack, which cannot achieve the function of graded trash interception. Moreover, when the device is working, since only one layer of perforated trash rack is designed, the staff needs to use cleaning tools to salvage the garbage in the channel, which is not easy to clean. Therefore, in response to the above problems, we propose a graded trash interception device for water channel. Utility Model Content
