Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the orientation terms such as left, middle, right, up, and down in the examples of the present invention are only relative concepts or refer to the normal use state of the product, and should not be considered as restrictive .

[0022] A dual liquid tank drone such as figure 1 and figure 2 As shown, it includes a frame 4 and two vertically arranged liquid tanks 2, and the two liquid tanks 2 are respectively located on both sides of the frame 4 and are arranged through the frame 4. The two liquid tanks 2 are detachably connected with the frame 4; Figure 4 to Figure 7 As shown, a horizontally arranged and bar-shaped communication container 1 is provided between the lower parts of the two liquid tanks 2, and the two liquid tanks 2 are plugged into the communication container 1 through plug-in valves 3. The plug-in valve 3 is installed in the ...

Abstract

The invention provides a double-liquid-tank unmanned aerial vehicle, which comprises a vehicle frame and two liquid tanks, wherein the two liquid tanks are located on the two sides of the vehicle frame respectively and arranged on the vehicle frame in a penetrating mode, and the two liquid tanks are detachably connected with the vehicle frame; a communicating container is arranged between the lower portions of the two liquid tanks, the two liquid tanks are plugged into the communicating container through plug valves, a warping rod is arranged in the communicating container, the middle of the warping rod is rotatably installed in the communicating container, and the two ends of the warping rod abut against switch pins arranged on the plug valves respectively. The liquid tanks are plugged into the communicating container through the plug valves, so that a communicating vessel structure can be quickly formed; the warping rod is arranged in the communicating container, and all the plug valves are conducted at the same time under the action of the warping rod, so that overflow of a plug port in the communicating container is prevented when the liquid tanks are mounted on the communicating container. Due to the arrangement of the two liquid tanks, the whole weight is large, the weight of the single liquid tank is small, the replacement and liquid adding are convenient, the size of the single liquid tank is small, the installation on the two sides of the vehicle frame is convenient, the balance is good, and the flight control is facilitated.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with two liquid tanks. Background technique [0002] With the development of the UAV market in recent years, small UAVs have been used more and more widely in consumer and industrial fields due to their low cost and ease of use. The advantages of simple structure, easy maintenance and vertical take-off and landing are quickly recognized by the market. At present, multi-rotor drones are mainly electric, and have developed in the fields of power inspection, logistics and transportation, public security and fire protection, agricultural plant protection, surveying and mapping, etc. [0003] In the field of agricultural plant protection, unmanned battery life and load are particularly important. On the premise of having a large battery life, it is required that the drone needs to carry a large weight of liquid medicine, so as to spray the ...
