Description

Technical Field

[0001] The present invention relates to the technical field of sampling devices, and particularly to a sampling device. Background Art

[0002] As an instrument for collecting water samples for analysis, a water quality sampler plays an irreplaceable role in environmental protection monitoring. By collecting and analyzing water samples, the pollution degree and change trend of water bodies can be evaluated, providing a decision-making basis for environmental protection departments.

[0003] After retrieval, a patent with Chinese patent number CN117517000B discloses a sampling device that is convenient for adjusting the sampling depth, including: a sampling unit, including a sampling bucket for obtaining water samples and a towing rope for towing the sampling bucket, and the towing rope is provided with scales for marking the depth of the sampling bucket sinking; a depth adjustment unit, including a fixing mechanism and a floating mechanism, the floating mechanism is arranged on the fixing mechanism, the fixing mechanism is arranged on the towing rope, and the fixing mechanism can move up and down along the towing rope and be fixed at any position on the towing rope to adjust the position of the floating mechanism on the towing rope, so as to set the depth of the sampling bucket sinking, and the floating mechanism floats on the water surface. This device can throw the floating mechanism and the sampling bucket together to the corresponding position in the river. At this time, the floating mechanism floats at the throwing point, and the sampling bucket naturally falls vertically, so as to achieve accurate sampling of the water body at the corresponding depth of the fixed position. The patent with Chinese patent number CN117517000B solves the problem that in the case of no boat, sampling can basically only be carried out at the position on the river bank. Although the sampling bucket can also be thrown to the middle position of the river by throwing, since the sampling bucket is generally pulled by a towing rope, the thrown sampling bucket cannot keep falling vertically at the throwing point, and it cannot be kept at a fixed depth after starting to sample at the corresponding depth.

[0004] However, in the actual use process of the above device, when sampling water bodies at different depths, it is necessary to repeatedly lower and recover the sampling device, which increases the total time required for sampling and reduces the sampling efficiency. Therefore, a sampling device needs to be proposed. Summary of the Invention

[0029] Embodiment 1

[0030] As Figures 1-6 shown, a sampling device includes an unmanned aerial vehicle 1. A plurality of telescopic rods 3 are fixedly connected to the outside of the unmanned aerial vehicle 1.

[0031] A hole 15 is opened outside the water body collection tank 8. An opening control mechanism is provided outside the water body collection tank 8. The opening control mechanism includes a second rotating shaft 23 provided outside the water body collection tank 8. A fifth connecting plate 26 is fixedly connected to the outside of the second rotating shaft 23. A first baffle 13 is rotatably connected to the outside of the fifth connecting plate 26. A second gear 25 is fixedly connected to the outside of the second rotating shaft 23. A third gear 27 is meshed and connected to the outside of the second gear 25. A sixth connecting plate 28 is fixedly connected to the outside of the third gear 27. A second baffle 14 is rotatably connected to the outside of the sixth connecting plate 28. The operation of the opening control mechanism causes the sizes of the first baffle 13 and the second baffle 14 blocking the hole 15 to change;

[0032] The second rotating shaft 23 is rotatably connected to the water body collection tank 8. The second gear 25 is rotatably connected to the water body collection tank 8. The first baffle 13 is slidably connected to the water body collection tank 8. The third gear 27 is rotatably connected to the water body collection tank 8. The sixth connecting plate 28 is rotatably connected to the water body collection tank 8. The second baffle 14 is slidably connected to the water body collection tank 8;

[0033] The rotating mechanism includes a second fixing plate 11 fixedly connected to the outside of the rotating table 9. A fixing rod 12 is fixedly connected to the outside of the second fixing plate 11. The side of the fixing rod 12 away from the second fixing plate 11 is fixedly connected to the water collection tank 8;

[0034] A U-shaped groove 20 is movably connected to the outside of the fixing rod 12. The U-shaped groove 20 is slidably connected to the second fixing plate 11. A fourth connecting plate 19 is fixedly connected to the outside of the U-shaped groove 20. The fourth connecting plate 19 is slidably connected to the second fixing plate 11;

[0035] A third connecting plate 18 is rotatably connected to the outside of the fourth connecting plate 19. A first rotating shaft 7 is fixedly connected to the outside of the third connecting plate 18. The first rotating shaft 7 is rotatably connected to the drone 1. A sliding sleeve 10 is slidably connected to the outside of the fourth connecting plate 19. The sliding sleeve 10 is rotatably connected to the rotating table 9. A rack 21 is fixedly connected to the outside of the U-shaped groove 20;

[0036] The rack 21 is meshed with a first gear 22. The first gear 22 is fixedly connected to a second rotating shaft 23. The second rotating shaft 23 is rotatably connected to a third fixing plate 24. The third fixing plate 24 is fixedly connected to the fixing rod 12.

[0037] In this embodiment, when it is necessary to sample the water body, the water body observation instrument 2 is controlled to reach the ideal position above the water body, so that the first rotating shaft 7 rotates. The rotation of the first rotating shaft 7 will drive the third connecting plate 18 fixedly connected to the outside to rotate. The third connecting plate 18 will cause the fourth connecting plate 19 rotatably connected to the outside to rotate outside the second fixing plate 11. The fourth connecting plate 19 will drive the U-shaped groove 20 fixedly connected to the outside to slide on the second fixing plate 11. And the rotation of the third connecting plate 18 will cause the fourth connecting plate 19 to drive the sliding sleeve 10 slidably connected to the outside to rotate outside the rotating table 9;

[0038] When the third connecting plate 18 drives the fourth connecting plate 19 and the U-shaped groove 20 to the side away from the second rotating shaft 23, at this time, the rack 21 fixedly connected to the outside of the U-shaped groove 20 will cause the meshing-connected first gear 22 to rotate. The rotation of the first gear 22 will drive the second rotating shaft 23 fixedly connected to the outside to rotate. The third fixing plate 24 rotatably connected to the outside of the second rotating shaft 23 is fixedly connected to the fixed rod 12, which can keep the second rotating shaft 23 stable when it rotates. The rotation of the second rotating shaft 23 will cause the fifth connecting plate 26 fixedly connected to the outside to rotate, that is, the first baffle 13 rotatably connected to the outside of the fifth connecting plate 26 can slide outside the water collecting tank 8. At the same time, the rotation of the second rotating shaft 23 will also drive the second gear 25 fixedly connected to the outside to rotate. The rotation of the second gear 25 will cause the meshing-connected third gear 27 to rotate. The rotation of the third gear 27 will cause the sixth connecting plate 28 fixedly connected to the outside to rotate;

[0039] The sixth connecting plate 28 will cause the second baffle 14 rotatably connected to the outside to slide outside the water collecting tank 8, that is, the first baffle 13 and the second baffle 14 will move closer to the middle at the same time until the first baffle 13 and the second baffle 14 completely block the hole 15. At this time, the third connecting plate 18 will drive the fourth connecting plate 19 and the U-shaped groove 20 to rotate to the outside of another second fixing plate 11 and slide to the side of the second rotating shaft 23. That is, at this time, under the meshing connection of the rack 21 and the first gear 22, the second rotating shaft 23 can rotate in the reverse direction, that is, the first baffle 13 and the second baffle 14 can move away from each other, and finally the hole 15 can be opened. At this time, the water collecting tank 8 with the first baffle 13 and the second baffle 14 in the open state can sample the water through the hole 15 without affecting the water collecting tank 8 with other first baffles 13 and second baffles 14 in the closed state. That is, it is convenient for the device to quickly perform multiple samplings, which can save sampling time and improve sampling efficiency.

[0040] Embodiment 2

[0041] As Figures 1-6 shown, a motor 6 is fixedly installed on the outside of the first fixing plate 5. The output end of the motor 6 is fixedly connected to the first rotating shaft 7. A depth control cylinder 4 is fixedly installed on the outside of the drone 1. The output end of the depth control cylinder 4 is fixedly connected to the first fixing plate 5.

A second connecting plate 17 is rotatably connected to the outside of the second baffle 14. The second connecting plate 17 is rotatably connected to the water collecting tank 8.

[0042] In this embodiment, the motor 6 fixedly installed outside the first fixing plate 5 facilitates the rotation of the first rotating shaft 7. When the depth control cylinder 4 is started, the depth control cylinder 4 causes the first fixing plate 5 provided at the output end to move up and down. The multiple water body observation instruments 2 fixedly connected to the outside of the first fixing plate 5 can keep the first fixing plate 5 in a stable state when it moves up and down. That is, by adjusting the height of the first fixing plate 5, water sampling at different depths can be achieved. The water body observation instrument 2 fixedly installed outside the unmanned aerial vehicle 1 facilitates the observation of the water body and helps to confirm the best sampling area of the sampling device. The first connecting plate 16 rotatably connected to the outside of the first baffle 13 is rotatably connected to the water body collection tank 8, and the second connecting plate 17 rotatably connected to the outside of the second baffle 14 is also rotatably connected to the water body collection tank 8, which can keep the first baffle 13 and the second baffle 14 stable when they rotate.
