Description

Technical Field

[0001] The utility model belongs to the technical field of drainage devices, in particular to a filtering structure for a drainage device for river construction. Background Art

[0002] During river channel construction, diversion ditches will be set up to divert water. The diversion ditches allow the river water in the river channel to be effectively drained, thereby preventing disasters caused by excessive river water flow during the flood season, and at the same time ensuring a considerable degree of safety performance.

[0003] When the water flow in the diversion ditch is too large or too small, a diversion device is needed to divert the remaining water. The diversion is usually carried out by the cooperation of a water pump and a water diversion hose. The device is simple and easy to carry. In order to prevent foreign objects in the river water from clogging the water diversion pipe, a filter cover head needs to be installed at the end of the water diversion pipe that contacts the water body. However, the connection between the filter cover head and the water diversion short pipe is usually fixed by bolts. In actual use, the filter cover head needs to be disassembled and assembled frequently for cleaning and maintenance. In this process, the bolts need to be rotated complicatedly, which is inconvenient. Therefore, a filtering structure for a river construction diversion device is needed, which can quickly disassemble and assemble the filter cover head and the diversion short pipe, thereby improving the convenience of cleaning and maintenance of the filter cover head in the later stage.
