A drone anti-swing liquid tank

Abstract

The invention discloses an anti-sloshing liquid box of an unmanned aerial vehicle, and belongs to the technical field of agricultural aviation plant protection machinery and equipment. The tank comprises a cylindrical box body, a central shaft andfan blades distributed symmetrically around the central shaft are arranged in the box body, the fan blades divide the box body into a plurality of symmetrically distributed accommodating space, and the inside of each accommodating spaces is provided with a liquid level sensor; a liquid outlet and a liquid inlet are formed in the box body,one sides ofthe fan bladesare fixed on the central shaft, and one end of the central shaft is connected to an actuator; the actuator controls the rotation of the central shaft according toliquid level informationdetected by the liquid level sensor to drive the accommodating space containingliquid to change to a position corresponding to the liquid outlet. The liquid level sensor installed in the central shaft of the cylindrical box body detects the liquid level information in the box and feeds the information back to a control system,the actuator is controlled to drive the central shaft to rotate so as to drive the fan blades to rotate, so that the liquid in the box sequentially flow out from the symmetrical accommodation space, the situation that the gravity center of the box body is always on the central shaft is ensured to the greatest extent, and the stability of the gravity center of the unmanned aerial vehicle is maintained.

Description

technical field [0001] The invention relates to the technical field of agricultural aviation plant protection machinery and equipment, in particular to an unmanned aerial vehicle anti-swing liquid tank. Background technique [0002] Pesticides are an effective means to prevent and control harmful organisms (diseases, insects, weeds, rats, etc.) and regulate plant growth. With the continuous development of economy and society, the demand for pesticides is still on the rise; More and more attention and application. The efficiency of traditional agricultural spraying is low. Using unmanned ultra-low-altitude drones to carry out agricultural and forestry plant protection operations has the advantages of high operating efficiency and small amount of spraying per unit area. In addition, since plant protection drones can be operated remotely from a distance, personnel do not need to enter the field for operations, which can fundamentally avoid the danger of workers being exposed t...

Problems solved by technology

[0003] Since the plant protection UAV needs to frequently perform acceleration and deceleration operations and flight attitude adjustments during the flight operation, with the use of the liquid in the liquid tank, when the liquid tank is not full, the liquid in the liquid tank will vibrate, which will drive the drone The human-machine body vibrates, which has a great impact on the follow-up flight of the drone, and is not conducive to the subsequent spraying operations
