Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a multi-nozzle unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicle, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and self-contained program control devices. It plays an important role in agriculture, forestry and other industries.

[0003] The current multi-nozzle drones generally install the nozzles under the rotors, or fix them under the fuselage of the drone through a bracket, and spray the liquid in the water tank on the drone to a preset position. However, during the spraying process of the existing drones, the liquid in the water tank will decrease, which will cause the vibration of the drone during flight or the shaking of the drone caused by wind to cause the liquid in the water tank to flow, which will further increase the shaking amplitude of the drone, affecting the stability of the drone flight, and in severe cases, causing the drone to fall. In addition, since the nozzles are set under the fuselage of the drone, when landing in the wild, especially when the landing ground is uneven, the nozzles are easy to hit obstacles, causing damage to the nozzles. For this reason, we propose a drone with multiple nozzles. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-Figure 4 A multi-sprinkler drone includes a shell 8, a plurality of rotors 7 are equidistantly mounted around the shell 8, a first U-shaped mounting plate 10 is mounted at the bottom of the shell 8, a second U-shaped mounting plate 11 is mounted at the bottom of the first U-shaped mounting plate 10, and a water tank 3 is mounted on the top of the second U-shaped mounting plate 11. Pesticides or water to be sprayed can be loaded into the water tank 3 for carrying.

[0026] like Figure 3 As shown, a water pump 21 is installed at the bottom of the second U-shaped mounting plate 11, and the water inlet end of the water pump 21 is connected to the inside of the water tank 3, and the water outlet of the water pump 21 is connected to a drain pipe 20, and a spray pipe 2 is installed at the end of the drain pipe 20, and the spray pipe 2 is fixed on the cross bar 12, and the cross bar 12 is fixed to the bottom of the second U-shaped mounting plate 11 through a fixing frame 15, and a plurality of spray heads 19 are equidistantly installed at the bottom of the cross bar 12, and each spray head 19 is connected to the spray pipe 2 through a pipeline. In actual use, the water pump 21 can transport the water in the water tank 3 through the drain pipe 20 and the spray pipe 2 to the spray head 19, and spray through the spray head 19, and because a plurality of spray heads 19 are provided, and the spray heads 19 are arranged in a row, the spraying area can be greatly increased;

[0027] like Figure 4 As shown, a first electric push rod 5 is installed on the top of the first U-shaped mounting plate 10, and the bottom of the first electric push rod 5 extends into the water tank 3, and a sealing push plate 22 is installed at the bottom of the first electric push rod 5. The sealing push plate 22 is in clearance with the side wall of the water tank 3. The sealing push plate 22 can reduce the volume in the water tank 3, thereby preventing the drone from shaking violently due to the flow of liquid in the water tank 3 during the spraying process, thereby improving the use effect;

[0028] It should be noted that a sealing strip is installed on the edge of the sealing push plate 22, so that when the sealing push plate 22 moves downward, the water in the water tank 3 will not flow to the top of the sealing push plate 22 to avoid residue.

[0029] A accommodating chamber 6 is provided inside the shell 8, and a controller 9 is installed in the accommodating chamber 6. A liquid level sensor 23 is installed at the bottom of the water tank 3. The controller 9 is connected to the first electric push rod 5 and the liquid level sensor 23 through wires. The liquid level sensor 23 can monitor the amount of liquid in the water tank 3 in real time and transmit the data to the controller 9. The controller 9 then controls the first electric push rod 5 to push the sealing push plate 22 downward so that the bottom of the sealing push plate 22 contacts the liquid surface, thereby preventing the liquid in the water tank 3 from shaking and affecting the stability of the UAV flight.

[0030] like Figure 1 and Figure 2 As shown, guard plates 1 are provided on both sides of the cross bar 12, and first connecting blocks 17 are symmetrically installed on the adjacent surfaces of the two guard plates 1. Second connecting blocks 18 are correspondingly installed on both sides of the cross bar 12, and the second connecting blocks 18 are rotatably connected to the first connecting blocks 17 through a rotating shaft. A connecting seat 14 is installed on one side of the top of each guard plate 1, and the top of the connecting seat 14 is rotatably connected to the second electric push rod 13, and the top of the second electric push rod 13 is rotatably connected to the bottom of the second U-shaped mounting plate 11. The second electric push rod 13 is connected to the controller 9 through a wire, and during the spraying process, the controller 9 can control the second electric push rod 13 to retract, and rotate the two guard plates 1 to the two sides of the nozzle 19 to expose the nozzle 19 for easy spraying.

[0031] It should be noted that if Figure 1 As shown, the guard plate 1 is L-shaped, and the two guard plates 1 form a U-shaped space, and the nozzle 19 is located in the space. When the nozzle 19 is lowered after spraying, the controller 9 can control the second electric push rod 13 to extend and rotate the two guard plates 1 to the bottom of the nozzle 19 to protect the nozzle 19 and avoid the nozzle 19 being damaged by collision during the lowering process.

[0032] like Figure 3 As shown, a distance sensor 24 is installed at the bottom of the cross bar 12. The distance sensor 24 is connected to the controller 9 through a wire. The distance sensor 24 can detect the distance between the nozzle 19 and the obstacle, and transmit the detection structure to the controller 9. The controller 9 can control the opening and closing of the two guard plates 1 in time.

[0033] Specifically, when the utility model is in use, the drone flies to a preset position, and the controller 9 controls the water pump 21 to work. The water pump 21 transports the liquid in the water tank 3 to the nozzle 19 through the drain pipe 20 and the spray pipe 2, and sprays it out from the nozzle 19 to irrigate the area below. During the spraying process, the liquid in the water tank 3 decreases and the liquid level drops. The liquid level sensor 23 transmits the detection result to the controller 9. The controller 9 then controls the first electric push rod 5 to extend, and the first electric push rod 5 pushes the sealing push plate 22 to move downward, so that the bottom of the sealing push plate 22 contacts the liquid surface, which can avoid the liquid in the water tank 3 from shaking during flight. When the spraying is completed and it needs to land, the controller 9 controls the second electric push rod 13 to extend, and the second electric push rod 13 pushes the guard plate 1 to rotate, so that the two guard plates 1 rotate to the bottom of the nozzle 19 to block the nozzle 19, so as to avoid the nozzle 19 from colliding with foreign objects and being damaged during landing.

[0034] Furthermore, Figure 4 As shown, a water inlet 4 is installed on one side of the water tank 3, and the water inlet 4 extends to the top of the water tank 3, and one end of the water inlet 4 close to the water tank 3 is located below the sealing push plate 22, so that liquid can be added to the water tank 3 through the water inlet 4, and when adding liquid, the liquid will not flow to the top of the sealing push plate 22, and the sealing push plate 22 will not block the water inlet 4.

[0035] Furthermore, Figure 1 As shown, legs 16 are installed on both sides of the bottom of the shell 8. The legs 16 extend under the guard plate 1, and there is a distance between the legs 16 and the guard plate 1. In this way, when landing, when the bottom end of the legs 16 touches the ground, there is still a certain distance between the guard plate 1 and the ground, and during the rotation of the guard plate 1, it will not collide with the legs 16.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
