It is composed of PLC, transmission mechanism, driving mechanism, and traction mechanism. Under the control of PLC, each mechanism cooperates with each other and orderly completes the purpose of automatic deployment of unmanned boats. After the mother ship receives the deployment signal, the unmanned boat is transported from the transmission mechanism to the car box at the top of the cabin, the car box lands, and the unmanned boat is pushed into the sea water by the driving mechanism. After completing a deployment instruction, the car box rises, and the deployment operation of the next unmanned boat is carried out; after the mother ship receives the recovery signal, the unmanned boat enters the car box at the bottom of the cabin, the car box rises, and the unmanned boat is pushed to the transmission mechanism by the driving mechanism, and is transmitted to the specified position.
