River channel ecological management device

Abstract

The invention discloses a river channel ecological management device which comprises a material collecting box arranged on a river channel liquid surface in an overhead manner. A material collecting cavity is formed in the middle of the material collecting box. The upper end face of the material collecting cavity is opened. A filtering net is arranged in the material collecting cavity. Insertion holes are formed in the two sides of the upper end face of the material collecting box. A set of springs are fixedly arranged on the bottom faces of each insertion hole. The outer side end face of each spring is fixedly connected with an insertion rod, and the outer side end of each insertion rod is fixedly connected with a water pump support. A positioning rod is arranged at the bottom of each water pump support. The bottom of each positioning rod is inserted in a river bed. A water pump is fixedly installed on the top of each water pump support, and an external power supply system supplies electricity to each water pump. The input end of each water pump is connected with a water pumping pipe, and each water pumping pipe penetrates the filtering net and stretches into the lower end face of the filtering net. The river channel ecological management device is simple in structure, water plant removing can be rapidly conducted on the river channel, the cleaning cost is reduced, the labor intensity of workers is lowered, a self-power-generation structure is adopted, and therefore the power utilization pressure is reduced.

Description

technical field [0001] The invention relates to the field of environmental management, in particular to a river channel ecological management device. Background technique [0002] In the river channel, there are often situations where a large number of aquatic plants overgrow and overgrow. In this case, manual work is required for cleaning, and the cleaning efficiency is very low. In addition, salvage ships are used in the process, which is costly and labor-intensive for the staff. The fishing efficiency is low and the fishing is not clean, which leads to the rapid reproduction of aquatic plants in the river. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a river channel ecological management device, which can quickly remove aquatic plants from the river channel, reduce cleaning costs and labor intensity of staff, adopt a self-generating structure, and reduce electricity consumption pressure. [0004] The prese...
