Inflation and deflation floating bag anti-vortex device of amphibious two-section vehicle

The invention discloses an amphibious two-section vehicle inflation and deflation floating bag anti-vortex device which comprises a floating bag, and a lock catch and a hinge which are connected with an amphibious two-section vehicle are arranged on the floating bag. The floating bags, the lock catches and the hinges are combined to serve as the anti-vortex baffles, the anti-vortex baffles are used for reducing vortexes generated at the hinged position of the amphibious two-section vehicle by water flow so as to reduce the influence of the water flow on the sailing speed of the amphibious two-section vehicle when the amphibious two-section vehicle runs on the water, meanwhile, certain buoyancy reserve is achieved, and the floating capacity of the vehicle can be improved; when the vehicle runs on land, the vehicle can be folded to the rear vehicle body and fixed through the lock catches, the floating bag is compressed and deflated to reduce the thickness, the vehicle body is not too wide, and the use requireme
