The invention discloses a ship capable of cleaning floating garbage on water. Long-strip-shaped
buoyancy bodies are symmetrically arranged on both sides of the lower portion of the ship capable of cleaning the floating garbage on the water. A narrow and long drainage channel is arranged between the two long-strip-shaped
buoyancy bodies, a garbage conveying device in a crawler type is arranged on the front section of the channel in an inclined upwards mode, and a crawler is a mesh type filter crawler (3). A
propeller drainage valve is installed on the rear portion of a water-flowing channel which is on the middle of a ship body, and the
propeller drainage valve comprises a
propeller (19) and five side valves which are arranged in a cross-type three-way pipeline. The propeller (19) is installed in the front section of an intermediate pipeline (12), and a main valve (S) is installed in the rear section of the intermediate
pipe (12). Left steering valves (L) and right steering valves (R) are installed on two side pipelines on the left and right sides. The main valve (S) arranged on the intermediate pipeline (12), a first side valve (M) arranged on a left side pipeline (20), and a second side valve (M') installed on a right side pipeline (18) are linked together.
