The invention discloses an anti-collision ship capable of going away from other ships through the wind speed difference during strong wind. The anti-collision ship structurally comprises an unmanned boat and a strong wind anti-collision device; the strong wind anti-collision device is installed on the unmanned boat and composed of a wind speed difference starting device, a blowing device and anti-collision rods; the blowing device is fixedly installed on the unmanned boat; and the wind speed difference starting device is connected to the top of the blowing device; and the blowing device communicates with the four anti-collision rods. The anti-collision ship has the beneficial effects that the device is started through the rotation speed difference between the wind rotation speed and the constant rotation speed during strong wind, the anti-collision rods are extended, the distances between the anti-collision ship and the other ships are increased, double buffering is conducted through an air bag and a sponge layer, and hard collision damage to the ship is decreased.
