Description

Technical Field

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

[0002] Dust suppressants are composed of new multifunctional high molecular polymers. After being sprayed on areas prone to dust, they can solidify into a film on the dust surface, thus having a strong dust suppression and dust prevention effect.

[0003] At present, most dust suppressants need to be sprayed with drones. However, when we use drones to spray dust suppressants, we find that because the drones are in the air, when the drones are spraying dust suppressants, if there are intermittent breezes or strong winds, the wind will blow the dust suppressants sprayed in the air to other locations, resulting in uneven dust suppressant spraying in some areas after spraying.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below in conjunction with specific embodiments.

[0031] Combination Figures 1 to 3 As shown, this embodiment is a spraying drone, including a drone component, a spray component, an adjustment component, a detection component and a control component.

In this embodiment, the stored medicine is a dust suppressant. An installation box 5 is provided at the bottom of the drone component. The spray component is provided on the installation box 5, and the spray component is at least partially connected to the storage barrel 3. The spray component is used to spray the dust suppressant. The adjustment component is arranged inside the installation box 5, and the adjustment component is connected to the spray component in a transmission manner. The adjustment component is used to adjust the spraying direction of the spray component. The detection component can detect the wind direction and wind speed information in real time, and the detection component can also detect the spraying direction of the spray component in real time. The control component is arranged in the installation box 5, and the detection component and the adjustment component are both connected to the control component in communication. The control component can determine the wind force based on the real-time wind direction and wind speed information, and drive the adjustment component according to the wind force, so that the adjustment component controls the spraying direction of the spray component, and then promptly remedies the unsprayed areas.

[0032] In some embodiments, the drone assembly includes a drone body 1 and a drone landing gear 2, a storage barrel 3 is installed on the top of the drone body 1, and an installation box 5 and the drone landing gear 2 are installed on the bottom of the drone body 1.

[0033] In some embodiments, such as Figure 2 As shown, the spray assembly includes a feed pipe 4, a first nozzle 7, a second nozzle 6 and a solenoid valve 13. A through hole is provided on the surface of the installation box 5 for the feed pipe 4 to rotate. The feed pipe 4 passes through the installation box 5 through the through hole and is rotatably connected thereto. The part of the pipe section located inside the installation box 5 is transmission-connected to the adjustment assembly inside the installation box 5, and the adjustment assembly can drive the feed pipe 4 to rotate around its own axis. A plurality of first nozzles 7 are evenly spaced along the axial direction on the feed pipe 4. Specifically, the plurality of first nozzles 7 are vertically and equidistantly arranged on the feed pipe 4. A second nozzle 6 is installed at the end of the feed pipe 4. Specifically, the second nozzle 6 is arranged at the end of the feed pipe 4 in an inclined shape. A solenoid valve 13 is also installed at the end of the feed pipe 4. The solenoid valve 13 is used to control the opening and closing of the second nozzle 6.

[0034] Furthermore, the included angle between the second nozzle 6 and the feed pipe 4 is 45°.

[0035] Furthermore, the feed pipe 4 is at least partially connected to the UAV landing gear 2, which can stabilize the feed pipe 4 and ensure the normal rotation of the feed pipe 4.

[0036] When the solenoid valve 13 is closed, the dust suppressant in the feed pipe 4 is sprayed outwards through the first nozzle 7 perpendicular to the feed pipe 4; when the solenoid valve 13 is opened, the dust suppressant in the feed pipe 4 is sprayed outwards through the first nozzle 7 and the second nozzle 6 respectively.

[0037] In some embodiments, such as Figure 3 As shown, the adjustment component includes a motor 9, a worm 16 and a worm wheel 8. The motor 9 is installed in the installation box 5, the motor 9 is connected to the control component for communication, the worm 16 is rotatably installed in the installation box 5, the output end of the motor 9 is connected to the end of the worm 16, and the motor 9 can drive the worm 16 to rotate around its own axis. The outer wall of the rod body of the worm 16 is threaded, and the worm wheel 8 is sleeved on the pipe body of the feed pipe 4 located inside the installation box 5. The outer wall of the worm wheel 8 is threaded to match the outer wall thread of the worm 16, and the worm wheel 8 and the worm 16 are meshed with each other.

[0038] The motor 9 drives the corresponding worm 16 to rotate around its own axis. The worm 16 and the worm wheel 8 are meshed together, so that the worm 16 drives the worm wheel 8, and the worm wheel 8 drives the feed pipe 4, so that the feed pipe 4 can rotate around its own axis, thereby adjusting the spraying angles of the first nozzle 7 and the second nozzle 6 on the feed pipe 4.

[0039] In some embodiments, the detection component includes a wind speed and direction sensor 15 and an angle sensor 14. The first end of the feed pipe 4 is equipped with a second nozzle 6 and a corresponding solenoid valve 13. The second end of the feed pipe 4 is equipped with an angle sensor 14. The angle sensor 14 can detect the rotation angle of the feed pipe 4 around its own axis in real time and transmit it to the control component. The bottom of the installation box 5 is equipped with a wind speed and direction sensor 15, which is used to detect wind direction and wind speed information in real time and transmit it to the control component.

[0040] In some embodiments, the feed pipe 4 is connected to the storage barrel 3 via a pumping assembly, and the pumping assembly can pump the dust suppressant in the storage barrel 3 into the feed pipe 4. Specifically, the pumping assembly includes an inlet pipe 11, a drain pipe 12 and a water pump 10. The water pump 10 is installed in the installation box 5. The water inlet end of the water pump 10 is connected to the storage barrel 3 via the inlet pipe 11, and the water outlet end of the water pump 10 is connected to the feed pipe 4 via the drain pipe 12.

[0041] In some embodiments, another form of the control component is manual control, specifically, an operator controls the rotation angle of the feed pipe 4 using a joystick.

[0042] The implementation principle of a spraying drone in this embodiment is:

[0043] In a windless state, the dust suppressant in the storage barrel 3 is pumped into the conveying pipe 4 by the water pump 10, and sprayed on the dust-generating area through a plurality of vertically arranged first nozzles 7.

[0044] In the windy state, the real-time wind direction and wind speed information is first detected by the wind speed and direction sensor 15, and the wind speed and direction sensor 15 transmits the wind direction and wind speed information to the control component. The control component obtains the real-time wind force according to the wind direction and wind speed information. The control component drives the motor 9 based on the wind force, and the motor 9 drives the worm 16 to rotate. Due to the meshing action between the worm 16 and the worm wheel 8, the worm wheel 8 further drives the feed pipe 4 to rotate, and the angle sensor 14 at the end of the feed pipe 4 can feedback the rotation angle of the feed pipe 4 to the control component. Then, the solenoid valve 13 is opened, so that the dust suppressant in the delivery pipe 4 is sprayed out through the second nozzle 6 which is arranged tilted. Since the rotation of the delivery pipe 4 and the second nozzle 6 will change the spraying direction of the second nozzle 6, the landing position of the dust suppressant is adjusted, so that the dust suppressant sprayed by the second nozzle 6 can be used to remedy the area behind the drone body 1 that has not been sprayed due to wind. At the same time, the rotated first nozzle 7 can also tilt the sprayed dust suppressant, thereby adjusting the landing point of the dust suppressant vertically sprayed by the first nozzle 7, effectively reducing the uneven spraying of the dust suppressant due to wind factors.

[0045] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
