Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a variable spraying pipeline. Background Art

[0002] Unmanned aerial vehicle, abbreviated as "UAV" in English, is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device, or operated completely or intermittently autonomously by an on-board computer.

[0003] Drones are widely used in fields such as spraying pesticides and painting. However, the spraying pipelines of existing drones are very simple and can only spray water or water mist with a specified flow rate. For example, they cannot quickly switch between mist and water flow spraying, or cannot quickly adjust when large or small flow rates are required. The functionality is simple. Therefore, we propose a variable spraying pipeline. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. The spraying pipeline of the existing drone is very simple and can only spray water flow or water mist with a specified flow rate.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A variable spray pipeline comprises a liquid storage chamber, a high-pressure water pump is arranged on the back side of the liquid storage chamber, an inclined plate is arranged inside the liquid storage chamber, a transverse liquid inlet pipe is arranged on one side of the inclined plate, the high-pressure water pump can pressurize the liquid in the transverse liquid inlet pipe and transport it to a plurality of spray pipes, the diameters of the plurality of spray pipes are different, so that the water output is different.

[0007] The bottoms of the plurality of spray pipes are connected with a first spray head structure and a second spray head structure, and the first spray head structure and the second spray head structure can spray the liquid to a specified effect.

[0008] As a preferred solution of the utility model, the liquid storage chamber can be connected to the drone through a top connector, and a protective shell is fixedly connected to the outer side of the high-pressure water pump, and the protective shell is fixedly connected to the liquid storage chamber.

[0009] The technical effect of adopting the above further solution is that the protective shell can protect the high-pressure water pump and prevent the high-pressure water pump from being damaged during flight or landing.

[0011] As a preferred solution of the utility model, several of the spray pipes are further provided with electromagnetic valves, and the front faces of several of the electromagnetic valves are provided with fixing parts.

[0012] The technical effect of adopting the above further scheme is: during the spraying process, the electromagnetic valve can control the opening and closing of a single corresponding spray pipe. When only a single spray pipe or a spray pipe with a specified flow rate is needed, the electromagnetic valves of all remaining spray pipes can be closed to ensure that only the current spray pipe is flowing.

[0013] As a preferred solution of the utility model, the first nozzle structure and the second nozzle structure are both detachable from the spray pipe, and the first nozzle structure and the second nozzle structure can be arbitrarily installed on one of the designated spray pipes according to usage requirements.

[0014] The technical effect of adopting the above further solution is that the first nozzle structure and the second nozzle structure can be arbitrarily installed on one of the designated spray pipes according to the use requirements, so that real-time switching is convenient according to the requirements.

[0015] As a preferred solution of the utility model, the first nozzle structure includes a first threaded cap, the bottom of the first threaded cap is fixedly connected with a plurality of first spraying ports, and a plurality of water outlets with different angles are arranged inside the plurality of first spraying ports.

[0016] The technical effect of adopting the above further solution is: the first nozzle structure discharges water in a stream-like manner, and the water outlet adopts a plurality of different angles to expand the spraying area.

[0017] As a preferred solution of the utility model, the second nozzle structure includes a second threaded cap, the bottom of the second threaded cap is fixedly connected with a plurality of second spraying ports, and a plurality of spraying ports with different angles are arranged inside the plurality of second spraying ports.

[0018] The technical effect of adopting the above further solution is: the second nozzle structure is to discharge water in a mist form, the spray port adopts spraying at different angles, and multiple spray ports are provided, so that the mist effect is good.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] In the utility model, a plurality of spray pipes with different diameters are provided, so as to achieve different water outputs, and at the same time, real-time switching between mist spraying and water flow spraying is possible. It is only necessary to install a plurality of first nozzle structures and a second nozzle structure at a plurality of spray pipes respectively before taking off the UAV, and then during the spraying process, the electromagnetic valve can control the opening and closing of a single corresponding spray pipe. When only a single spray pipe or a spray pipe with a specified flow rate is needed, the electromagnetic valves of all remaining spray pipes can be closed to ensure that only the current spray pipe is flowing, so that the water output can be adjusted in real time, and then when it is necessary to switch the spray state, the spray state can be adjusted, avoiding the problem that the spray pipeline of the existing UAV is very single and can only spray water or water mist with a specified flow rate, for example, when it is necessary to perform mist and water flow spraying, it is impossible to switch quickly, or when it is necessary to switch the water output between a large flow rate and a small flow rate, it is impossible to adjust quickly, and the functionality is single.
