The invention discloses a carbon fiber ship body recovery device based on an unmanned ship and relates to the technical field of unmanned ships. The carbon fiber ship body recovery device comprises acarbon fiber ship body. A recovery mechanism is mounted on the left side of the carbon fiber ship body. A dumping mechanism is mounted on the left side of the carbon fiber ship body and located on theright side of the recovery mechanism. A crushing mechanism is mounted in the carbon fiber ship body. The carbon fiber ship body recovery device based on the unmanned ship achieves the effect of driving a crushing rod to rotate through a first motor, has the function of crushing floating objects through the crushing rod, prevents large floating objects from blocking a first threaded rod, has the advantage that the floating objects can be taken out conveniently, achieves the effect of driving rolling wheels to rotate, has the function of integrally moving on the shore, prevents the floating objects from diffusing in the water again when the floating objects are taken out from the water, can discharge the floating objects on the shore and has the advantage of being good in recovery effect.
