Description

Technical Field

[0001] The utility model belongs to the technical field of water level monitoring, and specifically relates to a water level monitoring and early warning device based on water conservancy and hydropower engineering. Background Art

[0002] Hydropower is a clean energy that is renewable, pollution-free, has low operating costs, is convenient for power peak regulation, and is beneficial to improving resource utilization and the comprehensive benefits of the economy and society. It occupies an extremely important position in my country's energy development history and supports the sustainable development of the economy and society.

[0003] Water level monitoring is one of the important links in water conservancy and hydropower projects. At present, water level monitoring devices are generally used to achieve water level monitoring. They are usually installed near water bodies such as rivers, lakes, and reservoirs, and are specifically used to monitor and record water level changes. Water level monitoring devices are generally powered by solar cell modules. The solar panels are installed at an angle on the upper end of the bracket. Since the water level monitoring device is installed outdoors, environmental impurities (such as dust, bird droppings, mud, etc.) are easy to adhere to the solar panels. If these impurities are not cleaned, it will affect the normal operation of the solar panels. At present, manual regular or irregular cleaning is generally used, which not only consumes manpower, but also has low cleaning efficiency and poor cleaning effect. Utility Model Content
