Cleaning equipment and method for submerged plants

The invention relates to the field of river channel cleaning, and discloses a cleaning device and method for submerged plants, which have the following characteristics: the submerged plants are coiled by using a self-rotating winding roller and spikes, so that the generation of broken and fallen leaves is reduced, and the submerged plants to be cleaned are integrated together, so that the submerged plants can be cleaned subsequently, and the cleaning efficiency is improved. The submerged plants are pulled out, so that the growth number and growth vigor of the submerged plants are conveniently controlled, the removal frequency is increased, the wound submerged plants are expanded through the tensioning strips, the spines are separated from the submerged plants, the submerged plants are prevented from entering the winding rollers through gaps between the winding rollers and the spines, blocking is avoided, and the service life of the submerged plants is prolonged. In addition, the resistance between the submerg
