[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0025] Figure 1-4 As shown, the present invention provides a multi-axis unmanned aerial vehicle (UAV) water sampling system, including a UAV body 1 and a water sampling mechanism, wherein the water sampling mechanism is detachably installed on the lower side of the UAV body 1, which facilitates the replacement and cleaning of the water sampling mechanism.

[0026] Specifically, four support rods 21 are fixed to the lower side of the drone body 1 to form a mounting frame 2. The upper ends of the support rods 21 are fixed to the drone body 1, and the lower ends of the support rods 21 extend downwards and away from the center of the drone body 1. Mounting seats 211 are fitted onto the support rods 21, and support plates 22 are fixedly installed between the four mounting seats 211. The water-collecting mechanism is detachably mounted on the support plates 22. By moving the mounting seats 211 on the support rods 21, the distance between the mounting seats 211 is changed, allowing support plates 22 of different sizes to be fixed to the lower side of the drone body 1 to accommodate water-collecting mechanisms of different sizes.

[0027] An installation groove 221 extends from the center of the horizontal side of the support plate 22. A movable frame 3 is fixed on the outside of the water intake mechanism and assembled with the installation groove 221. The movable frame 3 includes a ring 31 and a latch 32 fixed on the support plate 22. The outer side of the ring 31 has a pre-set slot coaxially. By aligning the slot with the edge of the installation groove 221 and pushing the ring 31 into the installation groove 221, part of the support plate 22 is engaged in the slot, thereby limiting the up and down movement of the ring 31. The horizontal movement of the ring 31 is then restricted by the latch 32. The latch 32 includes a fixed seat 321 fixed on the support plate 22 and a stop bar 322 passing through the fixed seat 321. The stop bar 322 is threaded. After the ring 31 is installed in the mounting groove 221, the stop bar 322 is rotated until it abuts against the side of the ring 31 facing out of the mounting groove 221, thereby fixing the ring 31 horizontally. This completes the installation of the water intake mechanism under the UAV body 1.

[0028] The water intake mechanism mainly includes a water bucket 4, with an inlet / outlet 411 at the lower end and an vent 412 at the upper end. The water bucket 4 consists of a top plate, a body 41, and a bottom plate from top to bottom. The top plate has an vent 412 and a disassembly / removal slot 413, which is used for inserting and removing the detection unit 5. A support frame 43 is provided on the upper side of the bottom plate, and a fixing groove 432 is formed on the upper side of the support frame 43. A floating area 431 is formed between the support frame 43 and the bottom plate. A cover plate 42 is movably installed in the floating area 431. By moving the cover plate 42 up and down in the floating area 431, the inlet / outlet 411 can be sealed and opened.

[0029] The working principle of this invention is: Installation of water intake mechanism: First, select a matching support plate 22 and a water bucket 4. Then, install the support plate 22 between the support rods 21 of the fixing frame 2. Next, fix the water bucket 4 in the ring and insert the detection unit 5 from the top of the water bucket 4 until the detection unit 5 is snapped into the fixing groove 432. Finally, fix the ring body 31 on the support plate 22 and electrically connect the internal unit of the UAV body 1 at the upper end of the detection unit 5 to complete the installation of the water collection mechanism.

[0030] The process of obtaining water samples: The drone body 1 is started and takes off. After flying to the location where sampling is needed, it descends. Then, the water bucket 4 gradually enters the water body. At this time, the water sample pushes open the cover plate 42 and enters the water bucket 4. Then the drone body 1 rises again, and the cover plate 42 in the bucket 4 sinks again until the bucket 4 is completely removed from the water. The cover plate 42 also seals the inlet and outlet 411 under the bucket 4, completing the water sample collection. Example 2

[0031] The difference from Embodiment 1 lies in the installation method of the detection unit 5, specifically: Figure 5-6 As shown, in actual operation, if the inspection unit is simply plugged into the bucket 4, the drone may encounter special environments and experience flight turbulence during flight. The unfixed inspection unit 5 will bounce within it, which can easily damage the electrical connection at the top of the inspection unit 5 and its internal precision components. Therefore, it is necessary to fix the inspection unit 5.

[0032] A movable lock 6 for restricting the detection unit 5 is provided inside the support frame 43. The movable lock 6 mainly includes an adjusting rod 62 and a pin 61. The pin 61 is horizontally slidably preset inside the support frame 43. By sliding the pin 61, one end of it enters the fixing groove 432. A slot is preset on the outside of the detection unit 5. The slot adopts an annular groove structure. When the detection unit 5 is placed into the barrel 41, the detection unit 5 is fixedly installed by the cooperation of the pin 61 and the slot.

[0033] Furthermore, the adjusting rod 62 is vertically slidably pre-installed inside the support frame 43. A hinge 63 is provided between the upper side of the adjusting rod 62 and the pin 61. When the adjusting rod 62 moves up and down, the hinge 63 simultaneously drives the pin 61 to move horizontally, thereby allowing the pin 61 to enter and exit the slot, i.e., fixing and unlocking the detection unit 5. Additionally, the cover plate 42 is fixedly connected to the lower side of the adjusting rod 62, and the up and down movement of the cover plate 42 simultaneously drives the movement of the adjusting rod 62.

[0034] The working principle of this invention is: Installation of water intake mechanism: First, select a matching support plate 22 and a water bucket 4. Then, install the support plate 22 between the support rods 21 of the fixing frame 2. Next, fix the water bucket 4 in the ring and insert the detection unit 5 from the top of the water bucket 4 until the detection unit 5 is engaged in the fixing groove 432. At the same time, the detection unit 5 slides against the guide slope on the pin 61 until the pin 61 is aligned with the slot. The cover plate 42 moves down under gravity and drives the adjusting rod 62 to slide down again until the pin 61 enters the slot. Finally, fix the ring body 31 on the support plate 22 and electrically connect the internal unit of the drone body 1 at the upper end of the detection unit 5 to complete the installation of the water collection mechanism.

[0035] The process of obtaining water samples: The drone body 1 is started and takes off. At this time, the detection unit 5 is fixed by the pin 61 to avoid damage from accidental vibration. After flying to the location where sampling is required, it descends. Then the water bucket 4 gradually enters the water body. At this time, the water sample pushes open the cover plate 42 and enters the water bucket 4. Then the drone body 1 rises again, and the cover plate 42 in the bucket 4 sinks again until the bucket 4 is completely out of the water. The cover plate 42 also seals the inlet and outlet 411 under the bucket 4, locking the movement of the detection unit 5 again and completing the water sample collection.

[0036] After the drone returns to base, when releasing the water sample, the cover plate 42 needs to be pushed up to open, and the detection unit 5 needs to be unlocked again to facilitate the removal of the detection unit 5 and make it easier to clean the water bucket 4 and the detection unit 5 afterwards.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
