The form of the garbage fishing mechanism is various, and not only the lifting fishing type described above, but also the conveyor belt type in the implementation mode can be adopted. Since the floating garbage 500 is gathered continuously by the cooperation of the cleaning ship 100, the buoyant rope 200 and the floating anchor 400, when the transfer assembly 161 is inserted into the water in an inclined manner, the transfer assembly 161 is started, and the floating garbage 500 gathered on the transfer assembly 161 can be transferred to the cleaning ship 100 continuously and falls into the loading cabin of the cleaning ship 100. It will be appreciated by those skilled in the art that in order for the transfer assembly 161 to operate properly, other necessary fixed structures are required in addition to the connection base 162 to allow the transfer assembly 161 to be at a stable angle of inclination to the length of the cleaning vessel 100.

In particular, it is possible that the conveyor assembly 161 comprises a conveyor belt on the carrying surface of which a water screen (not shown) is provided. In order to maintain the conveying function of the conveyor belt, the conveying assembly 161 further includes at least two driving wheels, and the conveyor belt is driven to run by the rotation of the driving wheels. When the cleaning boat 100 starts to operate, the conveying assembly 161 is rotated along the connection part with the connection base 162, so that one end of the conveying assembly 161 which is originally totally above the deck 110 of the cleaning boat 100 is obliquely inserted into the water, and the power device on the conveying assembly 161 is started, so that the conveying assembly 161 operates, specifically, the conveyor belt operates, and the floating garbage 500 floating near the conveyor belt is continuously conveyed to the cleaning boat 100.

The baffle is installed in the both sides of conveyer belt, can prevent that solid-state rubbish from droing from the conveyer belt in the motion, ensures the high efficiency that rubbish was salvaged.

Optionally, in a specific implementation manner of the embodiment of the present application, as shown in fig. 1, a plurality of floating balls 300 are uniformly spaced on the floating rope 200, and the floating balls 300 are provided with hollow inner cavities. Through setting up hollow floater 300, can further improve the buoyancy of buoyant rope 200 for buoyant rope 200 stably floats on the surface of water, and exposes the surface of water certain distance, and avoid floating rubbish 500 to cross buoyant rope 200 and reveal.

Optionally, in a specific implementation manner of the embodiment of the present application, the floating anchor body 400 includes a processor, the processor is electrically connected to the power mechanism 410, the guiding mechanism 430, and the distance measuring mechanism 420, and the processor is configured to execute the following floating anchor body 400 control method:

detecting the distance between the floating anchor body 400 and a predetermined object;

if the distance is outside the first preset distance range, the power mechanism 410 is controlled to output power to drive the floating anchor body 400 to move towards the preset object until the distance is within the first preset distance range.

In connection with the foregoing, the water anchor 400 can maintain a distance from a predetermined object, which may be a bank such as a river bank, a lake bank, etc., in the water according to a preset requirement. Although the purpose can be achieved by adopting a high-precision GPS or Beidou navigation system, the structure of the bank edge is often complex, the high-precision navigation system cannot accurately guide the position of the floating anchor body 400, and once the position is deviated, the floating anchor body 400 can be damaged, or a larger gap is formed in a containment area formed by the floating cable 200, so that the floating garbage 500 cannot be contained. Through ranging mechanism 420 that sets up on the floating anchor body 400, monitor the interval of floating anchor body 400 and bank border at any time, when the distance at the floating anchor body 400 interval bank border is too big, the treater then sends the instruction to power unit 410 and guiding mechanism 430 for floating anchor body 400 moves towards the bank border, when moving to the first predetermined interval within range, stops power unit 410's work, makes floating anchor body 400 stop motion. If the mooring body 400 is too close to the offshore edge, the processor controls the power mechanism 410 to operate to drive the mooring body 400 to the offshore edge. In practice, of course, it may not be necessary to use the power mechanism 410 to drive the mooring body 400 to the offshore edge, and the mooring body 400 naturally has a tendency to move far from the offshore edge under the traction of the pontoon 200 and the clearing vessel 100.
