Description
Technical Field
The invention relates to the technical field of river channel cleaning, in particular to environment-friendly river channel and lake treatment cleaning equipment.
Background
The lake basin and the water body contained by the lake basin. The lake basin is a natural depression pool which is relatively closed on the ground surface and can store water. The lakes can be classified into tectonic lakes, laval lakes, glacier lakes, barrage lakes, karst lakes, adult lakes, Fengcheng lakes, Haicheng lakes, artificial lakes (reservoirs), etc. according to their causes. According to the drainage condition, the lake can be divided into an outflow lake (huff lake) and an inland lake; according to the salinity of the lake water, the lake water can be divided into a fresh water lake (the salinity is less than 1g/L), a salt water lake (the salinity is 1-35g/L) and a salt lake (the salinity is more than 35 g/L). The sources of lake water are precipitation, ground runoff and underground water, and some are from ice and snow melting water. The consumption of lake water mainly comprises evaporation, leakage, drainage and development and utilization, and according to the river channel grade division method, primary and secondary river channels mostly span large rivers of two or more provinces, and have great influence on the national economy and social development bureau, so the river channels are determined by the water conservancy department; the three-level river channels mostly affect one province or adjacent provinces, the importance degree of the three-level river channels is slightly less than that of the first-level river channels and the second-level river channels, but the three-level river channels also have considerable influence on regional national economy, and in order to enable the standards between provinces to be mastered substantially consistently and facilitate the grading of river channels across the provinces, the river channels of the type are negotiated with water conservancy (hydropower) halls (offices) of the provinces (autonomous regions and direct jurisdictions) by water conservancy ministry and commissions, and water conservancy departments are informed; the fourth and fifth river channels are identified by the water conservancy (hydropower) hall (bureau) of each province (autonomous region, direct district city). The river channel grade can be identified in batches in stages, the grade can also be lifted and lowered due to the change of conditions, and the program is identified when the program is changed. In consideration of the fact that the classification cannot be completely specified, the water conservancy department can directly specify the river channel grade under special conditions. The management of the river channels across countries or international boundaries relates to bilateral or multilateral relationships among countries, a domestic method cannot be completely used, classification can be temporarily avoided, and the river channels and lakes need to be cleaned by using cleaning equipment;
the existing cleaning equipment is poor in fixing performance, inconvenient to fix on different ship bodies for working and inconvenient to clean river channels and lakes at different depths, and therefore an environment-friendly river channel and lake treatment cleaning equipment is provided for solving the problems.
