3results about How to "Improve floating stability" patented technology

The application provides a small buoy and a coordinated action implementation method thereof. A buoyancy bag with a maximum diameter is designed in a middle cabin section of the buoy to adapt to a change in the central position of the buoy, and the buoy floating stability is improved. The buoyancy bag gas cylinder is designed to inflate the buoyancy bag, and the buoyancy bag is inflated and expanded to the designed diameter to adjust the buoyant center position of the buoy, so that the buoy floating posture is kept stable. The lifting gas cylinder is inflated to inflate the piston cavity, the thrust generated in the inflation instant is used to overcome the gravity, friction and tensile force of the breakable screw of the detection device, so that the detection device can move to the set height. The gas cylinder is inflated to inflate the sealing cavity of the telescopic mechanism, and the friction and shear pin resistance are overcome to expand the telescopic mechanism. The application provides a small buoy and a coordinated action implementation method thereof, and the detection device lifting and the buoy posture adjustment are realized in coordination. The coordinated action has high reliability, and the technical problems of the detection device lifting and the buoy posture dynamic adjustment in a small space are solved.

A floating wheelchair (1) includes: - a frame (2); - two floating rear wheels (6) mounted on the frame (2); and - a front wheel (7) mounted on the frame (2); and - a movement system (8) for alternating movement of the rear wheels (6) between a land position and a water position, wherein in the land position the rear wheels face each other on opposite sides of the frame and have a substantially transverse axis of rotation (9), and in the water position the axis of rotation (9) of the rear wheels is substantially vertical.

The application relates to the technical field of unmanned planes, in particular to a hydrogen fuel cell unmanned plane with an emergency function for sea deployment, which comprises a lower part of an unmanned plane body provided with supporting legs; the hydrogen fuel cell unmanned plane further comprises: containing bins which are symmetrically arranged on the two sides of the lower part of the unmanned plane body in pairs and relative to the supporting legs, the two containing bins are located on the outer sides of the supporting legs, hydrogen gas cylinder bodies are arranged in the containing bins, and the lower ends of the supporting legs are lower than the lower ends of the containing bins; pushing mechanisms which are connected with the two containing bins in pairs; and a driving source arranged between the two pushing mechanisms, the driving source is used for driving the two pushing mechanisms to synchronously push the two containing bins to move away from each other. The application improves the floating stability of the unmanned plane on the sea surface, and avoids the unmanned plane from being overturned due to swinging with sea waves.
