2results about How to "Improve floating stability" patented technology

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.
