Description

Technical Field

[0001] The utility model relates to the technical field of flood and drought disaster investigation, in particular to a water level monitoring device used for flood and drought disaster investigation. Background Art

[0002] Water level monitoring is an indispensable part of the process of flood and drought disaster investigation. Water level monitoring plays an important role in flood control, drought resistance, and collecting water level data. By monitoring the water level, flood and drought disasters can be investigated to make early warning preparations. In the prior art, commonly used water level monitors can be divided into float type, laser type, radar type and pressure type according to the principle. Taking the radar water level monitor as an example, the radar water level monitor needs to be installed above the water surface, and the distance between it and the water surface is detected by pulse radar wave ranging, and then the water level is measured. Then, the radar signal is collected and transmitted using the water level telemetry terminal to complete the water level monitoring.

[0003] Radar water level monitors usually need to be installed on a bracket, which is fixed on the river bank or bridge deck, and a cantilever is fixed on the upper end of the bracket. The radar water level monitor is fixed on the cantilever and placed directly above the river surface. Since the position of the radar water level monitor on the bracket is fixed, and the position of the bracket is also fixed after installation, when the radar water level monitor fails and needs to be repaired or replaced, maintenance personnel usually use a ladder to stand at a high place to remove the cantilever from the bracket, and then repair or replace the radar water level monitor. This is not only inconvenient to repair or replace the radar water level monitor, which brings a workload to the maintenance personnel, but also brings certain operational risks to the maintenance personnel. To this end, we propose a water level monitoring device for flood and drought disaster investigation. Utility Model Content
