Description

Technical Field

[0001] This utility model relates to the field of drone irrigation technology, and in particular to a drone-based crop irrigation component. Background Technology

[0002] Drone irrigation can quickly cover large areas of farmland. Compared to traditional ground irrigation methods, it is not limited by terrain. Drones can easily fly over complex terrains such as mountains and hills, precisely delivering water to the areas that need irrigation. Moreover, its irrigation speed is relatively fast, completing the irrigation of a field in a short time. Because of its precise irrigation method, water is more easily absorbed by plants, saving a significant amount of water compared to flood irrigation. Furthermore, in water-scarce areas, drone irrigation can rationally allocate irrigation water based on actual soil moisture and crop needs, improving water resource utilization efficiency.

[0003] During operation, drones are inevitably affected by human or external factors, causing changes in flight attitude, speed, and altitude. If the water in the tank carried by the drone is not properly restrained, it will vibrate. The shift in the center of gravity of the water in the tank and the impact on the tank wall reduce the flight stability of the agricultural drone, making it more difficult to control, and in severe cases, it may lead to a crash.

[0004] In the prior art, patents CN208403009U and CN211793923U disclose a drone medicine tank anti-vibration device and a drone anti-vibration medicine tank, respectively. These devices use spring-supported piston plates or push plates to constrain the liquid level, stabilizing the liquid surface and reducing the impact of the liquid on the sidewalls of the medicine tank, thus reducing vibration. However, both have inlets located on the bottom of the medicine tank, making it inconvenient to directly add liquid. The former requires drawing liquid through an external pipe, while the latter requires inverting the medicine tank and drone to add liquid, then flipping them back to their original position, which is very inconvenient. Furthermore, irrigation tanks are often larger than medicine tanks, making bottom-mounted liquid intake even more difficult. Utility Model Content

[0030] The utility model will be further described in combination with the examples below.

[0031] The specific embodiments of the crop irrigation assembly for unmanned aerial vehicle provided by the utility model are as follows:

[0032] Please refer to Figures 1-5 The crop irrigation assembly for unmanned aerial vehicle comprises a water tank 1, a hollow partition 2, a plurality of stepped through holes 3, a plurality of covers 6 and a plurality of plugs 7.

[0033] The water tank 1 is suspended below the unmanned aerial vehicle to contain irrigation water; the middle part of the water tank 1 is located below the body of the unmanned aerial vehicle, mounting plates 9 are arranged on both sides of the middle part of the upper end of the water tank 1, a plurality of strip-shaped holes are arranged on the mounting plates 9, and the water tank 1 and the body of the unmanned aerial vehicle are connected by bolts through the mounting plates 9 and the strip-shaped holes, so that the water tank 1 is suspended.

[0034] The water tank 1 is provided with reinforcing ribs on the outside. The reinforcing ribs strengthen the structure of the water tank 1 and reduce the deformation of the water tank 1.

[0035] Water tank 1 is equipped with a water pipe 11 and a water pump 14 at the bottom. The water pump 14 supplies water from water tank 1 into water pipe 11. Several nozzles 12 are provided at the bottom of water pipe 11. The nozzles 12 spray water to irrigate crops. As the water level in irrigation water tank 1 drops.

[0036] The middle part of the water pipe 11 corresponds to the lower side of the water tank 1. Several support plates 13 supporting the middle part of the water pipe 11 are provided on the lower side of the water tank 1. The water pump 14 is directly installed on the lower side of the water tank 1. The water inlet of the water pump 14 extends into the bottom of the water tank 1, and the water outlet is connected to the water pipe 11.

[0037] The hollow partition 2 slides vertically along the inner side of the water tank 1 and floats on the water surface. The hollow partition 2 has a hollow cavity, which allows it to float on the water surface by buoyancy. As the water volume changes, the hollow partition 2 rises and falls with the water surface. The hollow partition 2 is equipped with several vertical support columns to strengthen the structure of the hollow partition 2 and reduce its own deformation.

[0038] A vent 10 is provided in the middle of the upper wall of the water tank 1. As the water level and the hollow partition 2 inside the water tank 1 rise and fall, the volume of gas inside the water tank 1 changes. The vent 10 allows the gas inside the water tank 1 to communicate with the outside air, balancing the air pressure inside the water tank 1, and thus not affecting the changes in water volume and the position of the hollow partition 2.

[0039] Several stepped through holes 3 vertically penetrate the hollow partition 2 but do not communicate with the interior of the hollow partition 2; the stepped through holes 3 are symmetrically arranged at both ends of the hollow partition 2, and the vertical cross-sectional shape of the stepped through holes 3 is T-shaped, so that the stepped through holes 3 connect the upper and lower outer sides of the hollow partition 2.

[0040] Several lifting pipes 4 are connected to the upper side of the hollow partition 2. The number of lifting pipes 4 is the same as the number of stepped through holes 3 and they correspond one-to-one. The lower end of the lifting pipe 4 surrounds its corresponding stepped through hole 3. The lifting pipe 4 rises and falls with the rise and fall of the hollow partition 2.

[0041] The upper side of the water tank 1 is provided with several fixed pipes 5, the number of which is the same as the number of lifting pipes 4 and corresponds one-to-one. The lifting pipe 4 extends into the inside of the fixed pipe 5 and slides along the inside of the fixed pipe 5. The vertical sliding engagement between the lifting pipe 4 and the fixed pipe 5 also guides the lifting and lowering of the hollow partition 2, ensuring stable unidirectional lifting and lowering of the hollow partition 2 and preventing the hollow partition 2 from tilting relative to the water tank 1. In some embodiments, a sliding sealing rubber sealing ring is provided on the outer side of the upper end of the lifting pipe 4.

[0042] The fixed pipe 5 is vertically aligned with the stepped through hole 3, so the fixed pipe 5 is symmetrically located at both ends of the water tank 1. The middle part of the water tank 1 is connected to the drone body. The fixed pipe 5 does not affect the connection between the water tank 1 and the drone body.

[0043] Several covers 6 are detachably connected to the upper side of the water tank 1 and correspond vertically to each of the stepped through holes 3. Specifically, the covers 6 are detachably connected to the upper end of the fixed pipe 5. In this embodiment, the covers 6 and the fixed pipe 5 are connected by threads. The inner side of the covers 6 is provided with internal threads, and the outer side of the upper end of the fixed pipe 5 is provided with external threads that cooperate with the covers 6.

[0044] Several plugs 7 are sealed on the upper side of each stepped through hole 3, and springs 8 are provided between the plugs 7 and the caps 6 on their upper sides. The plugs 7 extend into the stepped through holes 3. The plugs 7 are disc-shaped structures with a T-shaped vertical cross section. In some embodiments, the lower side of the plugs 7 has a rubber layer, which can improve the sealing of the plugs 7 to the stepped through holes 3 and prevent water from passing through the stepped through holes 3 and entering the upper side of the hollow partition 2 when the springs 8 apply pressure to the hollow partition 2.

[0045] In this embodiment, the plug 7 is connected to the lower end of the spring 8, and the upper end of the spring 8 abuts against the lower side of the cover 6, making it easy to remove the plug 7. When the drone is flying to irrigate, the spring 8 is in a compressed state due to the limitation of the cover 6. The spring 8 presses the hollow partition 2 onto the water surface through the plug 7. As the water volume decreases, the spring 8 elastically extends, causing the hollow partition 2 to move down and press onto the water surface, applying pressure to the water surface and reducing the impact of water fluctuations on the side wall of the water tank 1, thereby reducing vibration.

[0046] After the water in water tank 1 is completely drained, the drone flies back to the water replenishment point, unscrews the cap 6, takes out the spring 8 and the plug 7, and directly injects water into the fixed pipe 5. The water passes through the inside of the fixed pipe 5 and the lifting pipe 4, and then flows through the stepped through hole 3 to the lower side of the hollow partition 2. As the water volume increases and the water level rises, the hollow partition 2 and the lifting pipe 4 rise. When the upper end of the lifting pipe 4 reaches the upper end of the fixed pipe 5, it indicates that the water is full. Align the plug 7 with the stepped through hole 3, insert the plug 7 and the spring 8, and then the cap 6 compresses the spring 8 and connects it to the fixed pipe 5 by thread, thus completing the water replenishment work.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
