An alarm 9 electrically connected to the contact switch 8 is arranged. The alarm 9 is an audible and visual alarm, which can perform audible and visual alarm operations at the same time. A wire hole is provided on the top side of the water inlet cylinder 1. The wires connected to the contact switch 8 and the alarm 9 pass through the wire hole. Four mounting plates 10 are fixedly connected to the outer surface of the water inlet cylinder 1. A connecting card slot 11 is provided on one side of the four mounting plates 10. The inner walls of the four connecting card slots 11 are all connected with connecting card blocks 12. An arc-shaped filter screen cover 13 is fixedly connected to the opposite side of two connecting card blocks 12. The arc-shaped filter screen cover 13 is convenient to install and remove through the connecting card block 12 and the connecting card slot 11.

[0034] 3) When the flood season comes, the river water will impact the arc baffle 16, and the telescopic rod 14 will shrink, and the buffer spring 15 will be compressed. Under the reaction force of the buffer spring 15, the arc baffle 16 will buffer the impact force of the river. In this process, the river water will enter the interior of the water inlet cylinder 1 through the water inlet trough 3, and the squeezing rod 7 will rise under the action of the guide float 5 and the lifting float 6. When the water level rises to a certain height, the squeezing rod 7 will squeeze the contact switch 8, and at this time the contact switch 8 will control the alarm 9 to perform an alarm operation.

[0035] To sum up, the river flood control water level warning device, through the coordinated arrangement of the water inlet cylinder 1, the adjustment fixing structure 2, the limit rod 4, the guide float 5, the lifting float 6, the extrusion rod 7, the contact switch 8, the alarm 9, the mounting plate 10, the connecting slot 11, the connecting block 12, the arc filter screen 13, the telescopic rod 14, the buffer spring 15, the arc baffle 16 and the water permeable hole 17, can not only adjust the warning water level of the device, but also perform protective operations on the water inlet cylinder 1 and perform multiple protective operations on the water inlet trough 3, thereby avoiding the situation where impurities block the water inlet trough 3, ensuring that the river water can normally enter the interior of the water inlet cylinder 1, thereby ensuring the normal progress of the water level warning process.
