Hydrological monitoring device with alarm structure

A hydrologic monitoring device with an alarm structure disclosed by the present invention comprises a device frame and the alarm structure installed on the device frame, the alarm structure comprises a guide cylinder and a second floating ball arranged in the guide cylinder, on a pair of opposite sides of the guide cylinder, one side is provided with a water permeable hole, and the other side is provided with a penetration hole. The size of the through hole enables the second floating ball to pass through the through hole; a control module and a second alarm device are packaged in the second floating ball, and when the control module judges that the second floating ball is separated from the guide cylinder, the second alarm device is controlled to give an acoustic alarm or a light alarm. The structure can effectively expand the alarm coverage range without depending on wireless data transmission. 本发明公开了一种带有报警结构的水文监控装置，包括装置架以及安装在装置架上的报警结构，所述报警结构包括导筒、设置在导筒内的第二浮球，在导筒的一对相对侧上，其中一侧上设置有透水孔，另一侧上设置有透过孔，所述透过孔的尺寸使得第二浮球能
