Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of water conservancy projects, and particularly relates to an irrigation water channel dredging device for water conservancy projects. BACKGROUND

[0002] An irrigation water channel is a network of artificial channels built by humans to guide and distribute water resources. Its core function is to transport water from sources such as rivers, lakes, and reservoirs to farmlands that need irrigation. It is not just a simple water channel, but a sophisticated system that integrates water collection, distribution, and control. Its forms are diverse, and the irrigation water channel system is increasingly scientific and engineered. The application of technologies such as concrete lining and gate pumping stations greatly reduces leakage and evaporation losses, improving water use efficiency. In today's context of increasing water scarcity, efficient irrigation water channels are crucial for food security and ecological sustainability. They help promote water-saving agriculture through precise irrigation and may support ecological water replenishment and urban water supply while considering agriculture;

[0003] With use, the irrigation water channel may become blocked, which can lead to a series of serious consequences. First, it can directly cause poor water flow, making it difficult for downstream farmlands to be irrigated in a timely and sufficient manner, which can lead to crop drought stress, reduced yield, or even crop failure, directly threatening food security. Blockage can also cause water levels to rise abnormally, increasing the structural load of the water channel and easily causing local breaches, flooding surrounding farmlands and facilities. At the same time, stagnant water bodies become breeding grounds for mosquitoes and other pests, worsening the regional sanitation environment. From a management perspective, dredging and unblocking work requires a large amount of manpower, material resources, and financial resources, significantly increasing operating costs. Therefore, water channel blockage is not only an engineering problem, but also a comprehensive challenge related to agricultural production, engineering safety, ecological health, and economic benefits, which must be prevented through regular maintenance and monitoring;

[0004] The conventional method for handling irrigation water channels is manual salvage, which is labor-intensive.
