Water intake system of unmanned aerial vehicle

Abstract

The invention provides a water intake system of an unmanned aerial vehicle. The water intake system comprises a winch and a water intake bottle; a wire reel is arranged in the winch; a suspension wireis wound around the wire reel and is led out from beneath a shell; the water intake bottle comprises a bottle cap, a bottle body and a bottle bottom; the suspension wire led out from beneath the shell is connected to the bottle cap; the bottle cap is provided with a plurality of openings; a movable cover is movably hinged to each opening; a circular-truncated-cone-shaped structure is formed at the bottle cap after the movable covers cover and seal the openings; the bottom surface of the bottle bottom is provided with a circular water inlet; a circular baffle is arranged above the water inlet;the radius of the water inlet is smaller than the radius of the circular baffle; and a plurality of limiting assemblies are arranged on the upper surface of the bottom surface of the bottle bottom and define a movable area above the water inlet. According to the water intake system, the bottom surface of the bottle bottom is provided with the circular water inlet, so that sampling is facilitated;and the bottle cap is in a circular truncated cone shape, so that the resistance of the water intake bottle in water can be reduced to a great extent, and the stability of the unmanned aerial vehicleis guaranteed.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a water intake system for unmanned aerial vehicles. Background technique [0002] UAVs can be used to sample water bodies that are far away from the shore or that are difficult to access. You only need to install a water bottle under the UAV and control the UAV to fly to the designated area, and then put down the water bottle to carry out the water collection operation. . [0003] In order to prevent water leakage, the water-taking bottle must be a closed structure, and if the water-taking bottle is a closed structure, water is difficult to enter the water-taking bottle smoothly, which is not convenient for sampling. In addition, after the sampling is completed, the water bottle will encounter a lot of resistance when it emerges from the water, which greatly affects the stability of the drone. [0004] Therefore, the prior art still needs to be improved and dev...

[0003] In order to prevent water leakage, the water-taking bottle must be a closed structure, and if the water-taking bottle is a closed structure, it will make it difficult for water to enter the water-taking bottle smoothly, which is not convenient for sampling

In addition, after the sampling is completed, the water bottle will encounter a lot of resistance when it emerges from the water, which greatly affects the stability of the drone.
