This design around the "natural, harmonious" theme, according to the state and the government's attention to the marine ecological environment, as well as the overall promotion of ecological civilization construction requirements, carried out a multifunctional surface cleaning robot device design work. This project mainly studies how to realize the collection of various sea surface garbage, complex oil pollution treatment, remote control, automatic cruise and other functions, and achieves the expected results: when the water surface cleaning robot is working, it provides forward power through the propeller; Floating bars and bright wheels collect garbage into the hull, mesh plates block solid floating garbage, and sweep solid garbage into the sewage collection bins on both sides through the movement of trash racks; in addition, the collected oil will enter the next link through the mesh plate, and the specific oil absorption material will absorb it, thus realizing the integration of the solid floating garbage and oil collection. The work flow has a clear division of labor, which is convenient for people to clean up the garbage and oil on the sea surface. The prototype of the multifunctional water surface cleaning robot device can play a good cleaning role in actual operation, which meets the needs of marine ecological restoration. The water surface cleaning robot is designed with exquisite structure, convenient use, diversified functions, and low energy consumption. Solar panels provide power and have a long service life. It is expected to be widely used to serve the society and meet the needs of ecological construction.
