Title:
GRAVITY-SENSING TWO-WAY PROPELLER AND WATER RESCUE ROBOT USING SAME
Document Type and Number:
WIPO Patent Application WO/2020/151372
Kind Code:
A9
Abstract:
A gravity-sensing two-way propeller and a water rescue robot using same. According to the propeller, one end of a power pump (2) is hinged and the other end thereof is arranged in a swinging manner, so that no matter which side of the water suction pipe (5) symmetrically arranged at the upper and lower sides faces downwards, the power pump (2) can swing under gravity to be communicated with the water suction pipe (5) positioned therebelow, thereby maintaining power propulsion of the water rescue robot; moreover, due to the isolation of the water suction pipe (5), the swinging of the power pump (2) will not be blocked regardless of whether a foreign matter is stuck in a water inlet grille (53), so that the propeller can perform gravity-sensing self-regulation in any working environment, and the rescue robot having the propeller can achieve gravity-sensing self-regulation of a power output direction in any working environment; furthermore, an inclination angle between the head of the rescue robot and a water surface is reduced, and the water resistance is reduced.
