[0003] Most of the existing safety monitoring and early warning devices for water conservancy projects use radar level gauges to detect the water surface in real time. The radar level gauge sends microwave pulses to the liquid surface and receives the reflected pulse signals, measures the time difference of the pulses propagating in the liquid, and thus calculates the height of the liquid surface. The radar level gauge is generally installed on a fixed rod and above the water surface. At the same time, an integrated control box, a rain gauge, and a camera are installed on the fixed rod to facilitate more comprehensive measurement of the water surface change and issue early warnings in a timely manner. In order to facilitate the maintenance of the electronic equipment above the rod body, some safety monitoring and early warning devices for water conservancy projects are provided with ladders on the rod body for maintenance personnel to climb. However, when the maintenance personnel reach the top of the monitoring and early warning device through the ladder, there is still a certain distance from the camera and the radar level gauge, resulting in the personnel being in a dangerous state during the detection and maintenance process, and it is not convenient to detect and maintain them. In view of the deficiencies of the prior art, the present invention provides a safety monitoring and early warning device for water conservancy projects to solve the above problems.
