Description

Technical Field

[0001] The present invention relates to the technical field of biodiversity assessment, and specifically to an unmanned aerial vehicle sampling and analysis system applied to biodiversity assessment. Background Art

[0002] Biodiversity is an important indicator to measure the health and stability of an ecosystem, which reflects the richness and diversity of species in the ecosystem. With the intensification of human activities, biodiversity is facing severe threats, such as habitat loss, environmental pollution, climate change, etc. Effective biodiversity monitoring and assessment are crucial for protecting the ecological environment and formulating protection policies. However, traditional biodiversity assessment methods mainly rely on manual sampling and laboratory analysis. These methods are usually time-consuming, laborious, and costly, and their efficiency and accuracy are limited when facing large areas or inaccessible regions.

[0003] With the development of unmanned aerial vehicle technology, the application of unmanned aerial vehicles in ecological monitoring is becoming more and more extensive, which can effectively reduce the labor intensity of manual work and improve work efficiency. For example, a water sampling unmanned aerial vehicle with a sampling confirmation function proposed in CN210774843U includes a water sampling unmanned aerial vehicle main body and a collection bottle. A sampling confirmation device is fixedly connected to the bottom end of the water sampling unmanned aerial vehicle main body, a collection bottle is fixedly connected to one end of the sampling confirmation device, and a fixing device is fixedly connected to one end of the water sampling unmanned aerial vehicle main body;

[0004] Although the above-mentioned unmanned aerial vehicle can perform sampling work, it still has the following defects: it can only perform one sampling each time and cannot perform multiple samplings, which affects the accuracy of the biodiversity assessment results. Moreover, when analyzing the sampled samples after sampling, it is necessary to control the unmanned aerial vehicle to fly back to a designated position (such as a laboratory) for manual analysis to carry out the biodiversity assessment work, which is relatively troublesome and has low work efficiency. Therefore, we propose an unmanned aerial vehicle sampling and analysis system applied to biodiversity assessment. Summary of the Invention

The main detection probe 215 is a water quality sensor detection probe, and the water quality analyzer 214 is a conventional device in this field and will not be described in detail here. The main detection probe 215 detects the water quality in the sampling bottle 205 and sends the detection data to the water quality analyzer 214 for analysis to obtain the water quality analysis result for biodiversity assessment; and,

[0059] There are two sets of sealing plates 217, which are used to close the through openings. The two sets of sealing plates 217 are both slidably arranged in the notches formed at the top of the covering frame 206 and are in contact with the sleeves 211. A sealed structure is formed in the inner cavity of the sleeves 211 through the two sets of sealing plates 217. On the opposite sides of the two sets of sealing plates 217, there are movable rods 218. The movable rods 218 movably penetrate through the convex blocks fixedly arranged in the notches, and the movable rods 218 play a guiding role in the movement of the two sets of sealing plates 217;

[0060] The connecting rod 219 has one end rotatably connected to the outer wall of the movable rod 218 and the other end rotatably connected to the top end of the hollow rod 212. It is used to drive the two sets of sealing plates 217 to move away from each other to open the through opening when the hollow rod 212 moves downward, so that the main detection probe 215 can enter the corresponding sampling bottle 205; and,

[0062] A wear-resistant rubber ring in contact with the top of the sealing plate 217 can be embedded at the bottom of the sleeve 211 to improve the sealing performance at the connection between the sleeve 211 and the sealing plate 217.

[0063] Preferably, the analysis part of this embodiment further includes:

[0064] The cleaning liquid tank 220 is arranged on the covering frame 206 and is used to store the cleaning liquid. A second liquid suction pump 221 is arranged on the cleaning liquid tank 220. The input end of the second liquid suction pump 221 is communicated with the cleaning liquid tank 220 through a pipeline, and the other end is communicated with the sleeve 211 through a liquid spraying pipe. After the main detection probe 215 detects the water body in a sampling bottle 205, then the main detection probe 215 enters the sleeve 211 along with the hollow rod 212. The bottom end of the sleeve 211 is closed by the sealing plate 217. At this time, the second liquid suction pump 221 is turned on to input the cleaning liquid in the cleaning liquid tank 220 into the sleeve 211 through the liquid spraying pipe to clean the main detection probe 215, ensuring the accuracy when the main detection probe 215 subsequently enters the next sampling bottle 205 for detection; and,

[0065] The third water pump 222 is arranged on the cleaning liquid tank 220. The output end of the third water pump 222 is communicated with the micro filter through a pipeline. The micro filter is a conventional device in the field and will not be described in detail here. The output end of the micro filter is communicated with the cleaning liquid tank 220. The input end of the third water pump 222 is respectively communicated with the inner cavities of two sets of sealing plates 217 through pipelines. Liquid inlet holes (not shown in the figure) communicating with the inner cavities of the sealing plates 217 are opened at the tops of the two sets of sealing plates 217 and at positions inside the sleeve 211. The cleaning liquid in the sleeve 211 can enter the inner cavities of the sealing plates 217 through the liquid inlet holes. By turning on the third water pump 222, the cleaning liquid can be pumped out, filtered through the micro filter and then circulated back to the cleaning liquid tank 220 for reuse, reducing resource waste and facilitating the subsequent detection and analysis work of the main detection probe 215;

[0066] Furthermore, a heating element, such as a heating sheet, can be installed on the inner wall of the sleeve 211 to dry the main detection probe 215 cleaned by the cleaning liquid.

[0068] The analysis part further includes:

[0069] A movable frame 223 is horizontally movably inserted into the bracket 201. One end of the movable frame 223 penetrates through the sleeve 211, and the other end is connected to the bracket 201 through a third telescopic device 224. The width of the movable frame 223 is smaller than the diameter of the sleeve 211. The third telescopic device 224 is used to drive the movable frame 223 to move horizontally relative to the sleeve 211. An activity port 225 for the main detection probe 215 and the hollow rod 212 to pass through is opened at one end of the movable frame 223 located inside the sleeve 211. The activity port 225 does not affect the up and down movement of the main detection probe 215 along with the hollow rod 212 and the flow of the cleaning liquid in the sleeve 211. A receiving groove 226 for accommodating the main detection probe 215 is opened on the movable frame 223 on one side of the activity port 225. The receiving groove 226 is used to pick up the main detection probe 215 when the main detection probe 215 is separated from the hollow rod 212.

Its inner diameter is greater than the outer diameter of the hollow rod 212 and less than the outer diameter of the main detection probe 215. It is used to drive the main detection probe 215 to disengage from the hollow rod 212 when the hollow rod 212 drives the main detection probe 215 upward to a preset position. Specifically, when the main detection probe 215 needs to be replaced, the telescopic device two 213 is used to drive the hollow rod 212 to drive the main detection probe 215 upward. At the same time, the telescopic device three 224 is used to drive the movable frame 223 to move, so that the receiving groove 226 is located within the sleeve 211.
