The invention relates to a water surface garbage cleaning ship. In the invention, a ship body is of an dual-body design, and the water surface garbage cleaning ship is composed of a detection and navigation system, a collection system, a garbage treatment system, a garbage unloading system and a propulsion system; and the water surface garbage cleaning ship can have three working modes, namely a free navigation mode, a landing operation mode and a non-landing operation mode. The water surface garbage cleaning ship can realize autonomous navigation and work, unmanned operation, full automation, good cleaning effect, strong flexibility, smoothness in working, safety and reliability by using the detection and navigation system to detect a region with garbage on the water surface. A scraper bucket chain network type collection and transmission device designed in the water surface garbage cleaning ship can realize the combination of continuous and intermittent work of recovery, thereby being energy-saving and high-efficient. Simultaneously, the device can change the amplitude up and down by hydraulic drive and fish floating objects in different water depths faster and more effectively.A satellite ship is designed for collaborative collection, thereby having better flexibility and high efficiency. The shoreside water surface floating objects and semi-floating objects are recovered and taken onto the ship by using a hydraulic rotary water spray gun to spray water.
