Description

Technical Field

[0001] The present invention relates to an agricultural and forestry remote sensing monitoring platform, and more specifically to an agricultural and forestry high-altitude remote sensing monitoring platform. Background Technique

[0002] Agricultural and forestry high-altitude remote sensing monitoring platforms rely more on scientific and technological equipment such as agricultural drones, which are breakthrough scientific and technological achievements that emerged in 2014. Agricultural drones are equipped with an automatic cruise GPS navigation system and a standard camera automatically controlled by the cruise system; the software on the ground allows the drone to take high-resolution ground pictures. The cruise software of the drone uses traditional radio to control the flight of the drone, including designing the flight path to cover the farm area to the greatest extent and controlling the camera for subsequent image processing. At a low resolution, it can allow farmers to see images that they couldn't see before. Compared with satellite images, the images taken by drones have a lower cost and higher resolution. Drones can provide farmers with three types of detailed information. First, observing crops from the air helps farmers discover irrigation problems, soil problems, and even pests and fungal diseases that are invisible to the naked eye. Second, the aerial camera can provide multi-level pictures, which can capture both ordinary visual spectrum photos and infrared photos to help farmers discover crop health problems that are invisible to the naked eye. Third, the drone can fly once a week, once a day, or even once an hour, and can provide time-ordered animations to demonstrate the growth changes of crops, providing opportunities for better crop management or discovering problems. This is part of the trend of data-driven agricultural development.

[0003] In the existing drone platform, due to the defect in the structural design, there are problems such as how the drone can land smoothly on uneven ground and tipping over on the ground due to the lack of shock absorption ability during landing. Summary of the Invention

[0015] The present invention provides an agricultural and forestry high-altitude remote sensing monitoring platform, which has the following beneficial effects:

[0016] 1. For this agricultural and forestry high-altitude remote sensing monitoring platform, a sampling mechanism is provided. The first electric push rod drives the soil sampler to enter the soil for sampling and then return to the original position. The third electric push rod pushes the fourth electric push rod below the soil sampler, and the fourth electric push rod pushes into the soil sampler. The second electric push rod squeezes downward, and the soil in the soil sampler falls into the test tube through the delivery pipe. When the UAV flies to the next sampling location, the first annular slide rail rotates to drive another empty test tube below the delivery pipe, and so on. When the UAV takes soil samples, it takes soil samples from different regions and stores them separately, avoiding interference between the detection results of soils in different regions and improving the accuracy of the detection results.

[0017] 2. The agricultural and forestry high-altitude remote sensing monitoring platform is equipped with a cleaning mechanism. The fifth electric push rod pushes to block the delivery pipe, and the sixth electric push rod pushes to discharge the soil in the delivery pipe into the soil sampler. The second electric push rod pushes to discharge the soil inside the soil sampler. The water pump pumps the water in the water tank into the spray ring through the first water delivery pipe to clean the soil attached to the inner wall of the soil sampler. The second annular slide rail drives the spray ring to rotate. The water pump pumps the water in the water tank into the spray box through the second water delivery pipe to clean the soil attached to the inner wall of the delivery pipe. At the same time, the sixth electric push rod pushes the spray box to reciprocate inside the delivery pipe. After the cleaning is completed, the resistance wire is started, and the sixth electric push rod pushes the resistance wire to reciprocate inside the delivery pipe. After the sampling is completed, the drone can self-clean the sampling mechanism to avoid the residual soil in the mechanism from mixing with the next sampling, and at the same time dry the residual water stains inside the fuselage to prevent them from flowing into the fuselage and causing pollution.

[0018] 3. The agricultural and forestry high-altitude remote sensing monitoring platform is equipped with a support mechanism. The eighth electric push rod pushes the support plate so that the inner sleeve and the outer sleeve are in interference fit. When the drone body lands, the seventh electric push rod slowly contracts to a suitable position, and the drone can land on uneven ground, improving the working range of the drone.

[0019] 4. The agricultural and forestry high-altitude remote sensing monitoring platform is equipped with a shock absorption mechanism. When the drone body lands on the ground, a reaction force will drive the sliding plate to press down. The sliding plate drives the second connecting rod to press down. The second connecting rod drives the sliding rod to roll at the bottom of the shock absorption box. The sliding plate drives the first connecting rod to press down the spring. The spring rebounds under force. The sliding plate and the first connecting rod are then pressed down by gravity and so on until the reaction force completely disappears, avoiding the drone from tipping over due to the reaction force caused by falling too fast, making its landing smoother, avoiding unnecessary losses, and improving the safety of the drone.
