Description

Technical Field

[0001] The invention relates to a plant protection unmanned aerial vehicle, and in particular to a device for monitoring the deposition path of spray droplets from an intelligent plant protection unmanned aerial vehicle. Background Art

[0002] Plant protection drones are unmanned aircraft used for agricultural and forestry plant protection operations. They are mainly composed of three parts: a flight platform, a navigation flight control system, and a spraying mechanism. They can spray pesticides, seeds, powders, etc. through ground remote control or navigation flight control. Furthermore, plant protection drones have the advantages of low operating altitude, less drift, hovering in the air, and no need for a dedicated take-off and landing airport. The downward airflow generated by the rotor helps increase the penetration of the fog flow on crops, with a high prevention and control effect. They can also be remotely controlled from a distance to avoid the risk of spraying workers being exposed to pesticides, thereby improving the safety of spraying operations. In addition, the spraying technology of plant protection drones uses a spray spraying method, which can save at least 50% of the use of pesticides and 80% of water, greatly reducing costs.

[0003] During the actual operation of plant protection drones, the spray droplets are prone to drift, and the existing technology lacks technology that can monitor the droplet deposition path in real time, making it difficult to accurately monitor the direction of the droplets falling in real time, and the spraying quality needs to be improved. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned problems and provide a monitoring device for the droplet deposition path of spraying of an intelligent plant protection UAV. The monitoring device can monitor the droplet deposition path in real time, facilitate timely adjustment of the spraying posture, and help improve the spraying quality.

[0005] The purpose of the present invention is achieved through the following technical solutions: An intelligent plant protection UAV spraying droplet deposition path monitoring device comprises a UAV body and a spraying mechanism and a droplet monitoring mechanism arranged on the UAV body; The spraying mechanism includes a medicine box, a delivery pump, a delivery pipe and a nozzle; the delivery pipe and the nozzle are provided in plurality; The droplet monitoring mechanism includes a panoramic camera and a wind curtain barrier mechanism, wherein the panoramic camera is arranged at the bottom of the drone body and faces downward, and the panoramic camera is electrically connected to the controller of the drone body; The wind curtain baffle mechanism includes a blower and an annular wind curtain tube, the blower is connected to the annular wind curtain tube through a pipeline; the annular wind curtain tube is fixedly arranged at the bottom of the drone body, and an annular air outlet is arranged at the bottom of the annular wind curtain tube; in an upward projection, the annular wind curtain tube is located at the center of multiple nozzles, and the panoramic camera is located at the center of the annular wind curtain tube.

[0006] The working principle of the above-mentioned intelligent plant protection drone spray droplet deposition path monitoring device is as follows: When working, the liquid medicine in the medicine box is sprayed downward through the nozzle, and the panoramic camera is used to obtain images downward, and the images are transmitted to the controller of the drone body for analysis. If the droplets only move downward without lateral displacement, in the perspective of the panoramic camera, the droplets sprayed by multiple nozzles form a uniformly distributed picture; if the droplets drift in a certain direction, the image obtained by the panoramic camera will show that the entire droplets are offset in that direction, so that the deposition path of the droplets can be analyzed and simulated, and the flight posture of the drone body can be controlled by the controller to offset or suppress the drift phenomenon, so that the droplets fall vertically as much as possible, which is conducive to improving the spraying quality.

[0007] Furthermore, since the panoramic camera is set at the bottom of the drone body and located in the middle of multiple nozzles, if the fog droplets drift laterally, it is easy to cover the panoramic camera. To this end, the blower provides high-pressure gas and delivers it to the annular wind curtain pipe. The high-pressure gas is ejected downward from the annular air outlet to form an annular high-speed wind curtain, which can block the fog droplets and prevent the fog droplets from covering the panoramic camera, thereby ensuring the normal monitoring work of the panoramic camera.

[0008] In a preferred embodiment of the present invention, a position for placing a medicine box is provided in the drone body.

[0009] In a preferred embodiment of the present invention, two rotatable landing gears are provided at the bottom of the drone body.

[0010] Furthermore, in the spraying working state, the lifting and lowering frame is in a retracted state so as not to affect the spraying and monitoring work.

[0011] In a preferred embodiment of the present invention, there are six delivery pipes and six nozzles, and the six delivery pipes are evenly distributed along the circumferential direction; the six nozzles are arranged at the ends of the six delivery pipes.

[0012] A preferred embodiment of the present invention is that the blower is electrically connected to a controller of the drone body, and in a working state, the controller of the drone body simultaneously controls the blower and the delivery pump to operate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The monitoring device of the present invention can monitor the droplet deposition path in real time, which is convenient for timely adjustment of the spraying posture and is beneficial to improving the spraying quality.

[0014] 2. High-pressure gas is provided by the blower and transported to the annular air curtain pipe. The high-pressure gas is ejected downward from the annular air outlet to form a high-speed air curtain, which can block the fog droplets and prevent the fog droplets from covering the panoramic camera, thereby ensuring the normal monitoring work of the panoramic camera.

If the droplets only move downward without lateral displacement, in the perspective of the panoramic camera 6, the droplets sprayed by multiple nozzles 5 form a uniformly distributed picture; if the droplets drift in a certain direction, the image obtained by the panoramic camera 6 will show that the entire droplets are offset in that direction, so that the deposition path of the droplets can be calculated and simulated, and the flight posture of the drone body 1 can be controlled by the controller to offset or suppress the drift phenomenon, so that the droplets fall vertically as much as possible, which is conducive to improving the spraying quality.

[0026] Furthermore, since the panoramic camera 6 is arranged at the bottom of the drone body 1 and is located in the middle of the multiple nozzles 5, if the fog droplets drift laterally, it is easy to cover the panoramic camera 6. To this end, the blower 7 provides high-pressure gas and delivers it to the annular wind curtain pipe 8.
