Description

AUTONOMOUS UNMANNED AERIAL VEHICLE INTEGRATION AND SYSTEM
PERFORMING HYBRID SPRAYING
Subject of the Invention
The invention relates to an autonomous unmanned aerial vehicle integration and system that can perform hybrid spraying and has different aerofoil structures that can perform agricultural irrigation and disinfection.
State of Art
In agricultural fields, manned or unmanned aerial vehicle systems are used for agricultural disinfection or irrigation or for spraying from the air for any circumstance. However, because of the size, cost and carbon footprint of the manned aerial vehicles and the problems such as harmful exhaust residue they leave on the plants, the interest in the unmanned aerial vehicles (or drones) has increased recently.
In the prior art, quadcopters, hexacopters, octocopters or helicopters have been used for drone systems. The liquid taken from the tank placed on the drone bodies where they are required is sprayed via wind or pressure difference. Even though a certain amount of load can be carried in this system, this system cannot provide practicality. The fact that the impact areas swept at one shot by the spraying areas present in these systems are limited creates disadvantages.
It is known that in aerial vehicle systems, an important amount of the energy is spent at take-off and landing. Accordingly, it is seen that specifically the rotating wing systems provide the impulse that creates a single force to preserve their levels constantly from the engines. In this case, in aerial vehicle systems, an additional force is required at take-off. By this way, less energy will be consumed, and the saved energy will provide a longer flight range. However, there are no aerial vehicle systems developed for this purpose in the prior art.
The documents described below can be considered examples of the prior art.
Invention of the utility model document no CN205239920U relates to a unmanned aerial vehicle (drone) developed to agricultural spraying quality and efficiency. The advantages of the unmanned aerial vehicle of the invention can be described as increasing the flow rate and spraying range of the water delivered from the sprinklers by the water pump located in the water tank and achieving high-quality spraying performance that is not affected by the wind. However, in this invention, there are no fixed wings that will support the take-off power of the drone.
The invention of the document no CN106069596A relates to a drone developed for the agricultural watering activities in the broadest terms. The drone of the invention comprises a body, flying mechanism, power mechanism, watering mechanism and support frame. In this patent document relating to drone use in agricultural areas, a development related to easy movement or take-off of the drone or having a larger impact area by expanding the spraying area is not mentioned.
It is seen that the inventions described in these mentioned documents do not have developments related to a wing structure that will support the take-off power or a spraying system that will provide a larger spraying field and thus, the disadvantages in the prior art continues. In this case, a unmanned aerial vehicle (drone) system that spends less energy during take-off and landing and that has a more economic spraying system is needed .
The invention of the patent application provides an autonomous unmanned aerial vehicle system that can perform hybrid spraying that comprises wings having a structure to expand the spraying area and inclined surfaces that will support the take-off power, which will eliminate the abovementioned disadvantages.
Detailed Description of the Invention
The invention relates to an autonomous unmanned aerial vehicle which comprises different wing structures that can perform irrigation or disinfection for agricultural purposes. As the said invention comprises both movable (rotating) and fixed structures, it provides a forward manoeuvre consuming less energy by wings creating a take-off force in forward movements and thereby a longer flight time and range. It provides an easier vertical take-off with its rotating wing structure (12) and a possibility to glide with its fixed wing structure (4) . In the unmanned aerial vehicles of the invention, there are sprinkler elements (2) that can be placed in desired width and range. By these sprinkler elements (2), the liquid stored in the tank (5) depending on the intended use (irrigation or disinfection) of the unmanned aerial vehicle is released. As a result of the development of these sprinkler elements (2) with the invention, the liquid is released to a larger area expanding the influence area .
The unmanned aerial vehicle of the application, on the most basic terms, consists of a multirotor engine (1) that provides the required mechanical energy, sprinklers (2) that delivers the liquid through spraying, engine holders (3), fixed wing (4), tank (5) storing the liquid to be sprayed, a pump that delivers the liquid in the tank (5) to the sprinklers (2), an engine (6) with a vertical take-off movement, a servo engine and pin set (7), ESC engine controller (8), Li-Po Battery (9), autonomous flight control system (10) responsible for the flight and control of the unmanned aerial vehicle and multirotor propeller elements (11) · In one embodiment of the invention, the tank (5) is located on the body, in proximity to the centre of gravity.
Autonomous flight control system (10) ensures that the unmanned aerial vehicle serves as desired giving results based on the required decisions. Multirotor propellers (11) are propellers used for multirotor engine (1) . Servo engines are used to control a surface or a structure.
In one embodiment of the invention, Lithium-Polymer batteries (Li-Po Battery (9)) in which the required electric energy is stored are used.
In one embodiment of the invention, the gaps between the sprinklers (2) placed at the bottom of the fixed wing (4) structure can be arranged depending on the intended use. The arrangement of these gaps and the number of placed sprinklers (2) provides the required practicality.
The important features of the unmanned aerial vehicle of the invention are comprising fixed wings (4) with inclined surfaces that support the take-off power in addition to the rotating wings (12) and having sprinklers (2) placed from one end to another underneath these fixed wings (4) . The fact that the unmanned aerial vehicle of the invention has both rotating wing (12) and fixed wing (4) structure (that is has a hybrid structure) ensures that less energy is consumed, forward manoeuvre is achieved, and flight range is increased by contributing to flight duration as the wing creates a take-off force in the forward movements. The unmanned aerial vehicle having a structure that can perform vertical take-off (VTOL) with its rotating wings (12) and glide with its fixed wings (4) helps the unmanned aerial vehicle to eliminate the energy consumption problem of the vehicles of the prior art.
The fixed wings (4) of the system of the invention not only allows spraying a large area, but also contributes to the lift of the vehicle stemming from speeds occurring towards forward. Fixed wing (4) structures consists of inclined surfaces and comprises an aerofoil wing structure. By means of this wing structure, it is ensured that the unmanned aerial vehicle acquires a lift from the wing in forward acceleration making use of Bernoulli principle. By means of this force obtained, the load required for the multirotor engines (1) and multirotor propellers (11) are decreased and efficiency is increased.
Besides the energy saving advantages provided by the developed unmanned aerial vehicle of the invention, as it has sprinklers (2) arranged underneath its large fixed wings (4) from one end to another, the influence area to be sprayed is increased. The use of fixed wings (4) creates a larger area to arrange more sprinklers (2) and using more sprinklers (2) allows the unmanned aerial vehicle to sweep and spray a larger area at one shot.
Briefly, the invention is a multirotor autonomous unmanned aerial vehicle for agricultural spraying; wherein it comprises more than one rotating wings (12) that allows it to take off vertically and more than one vertical take-off movement engine (6) connected to these rotating wings (12), a fixed wing (4) system having inclined surfaces (aerofoil wing structure) that allows acquiring lift from the wing, and sprinklers (2) placed on the fixed wings (4) for spraying.
In addition to these advantages of the system of the invention, it can be mentioned that it has features such as it can be used in humidifying the plants from air and it contributes to the pollination of the plants.
