[0002] Environmental monitoring is to determine the environmental pollution status and the level of environmental quality by monitoring and measuring indicators that reflect environmental quality. Water quality monitoring is an important part of environmental monitoring. When monitoring environmental water quality, it is necessary to sample the water body to facilitate its monitoring.

[0003] The Chinese patent with the public publication number CN214309692U discloses a drone-mounted water quality sampling module device, including a drone and a sampling device; the drone includes a drone body and a plurality of arms arranged on the side wall of the drone body; the sampling device includes a mounting plate, a clamp, a support rod, a water sampling cylinder, a piston, a lifting mechanism, a cover, a water inlet pipe and a one-way valve;

[0025] like Figures 1 to 4As shown, a drone water sampling device comprises a drone body 1, a landing gear 11 is arranged on the surface of the drone body 1, and a floating plate 2 is fixedly installed on the surface of the landing gear 11, a lifting mechanism 3 is fixedly installed on the surface of the drone body 1, a waterproof cover 4 is fixedly installed on the top surface of the moving part of the lifting mechanism 3, a water storage component 5 is arranged on the bottom surface of the moving part of the lifting mechanism 3, and a driving mechanism 6 is arranged on the top surface of the moving part of the lifting mechanism 3 and the inside of the water storage component 5, a piston 8 is fixedly installed on the bottom surface of the moving part of the driving mechanism 6, and a one-way sealing mechanism 7 is arranged on the bottom of the water storage component 5. More specifically, after the drone body 1 flies to the sampling water area, the drone body 1 is lowered onto the water surface so that the float 2 contacts the water surface. The buoyancy of the float 2 makes the drone body 1 float on the water surface. The water storage component 5 is moved vertically by the lifting mechanism 3. After the water storage component 5 is inserted to the sampling depth, the driving mechanism 6 drives the piston 8 to move vertically inside the water storage component 5, thereby generating negative pressure inside the water storage component 5. Under the action of the negative pressure, water pushes open the one-way sealing mechanism 7 and enters the interior of the water storage component 5 to achieve sampling. After sampling, the drone body 1 takes off to transport the sample.

[0026] The lifting mechanism 3 includes a guide rail 301, and the left and right side walls of the drone body 1 are fixedly installed with the guide rail 301, and the top surface of the guide rail 301 is fixedly installed with a first motor 302, and the output end of the first motor 302 penetrates the top surface of the guide rail 301 and is fixedly installed with a threaded rod 303, and the surface of the threaded rod 303 is threadedly sleeved with a vertical frame 304, and the opposite surfaces of the two groups of vertical frames 304 are fixedly installed with a horizontal frame 305, and the top surface of the horizontal frame 305 is fixedly installed with a waterproof cover 4, and the front side wall of the guide rail 301 is provided with a scale line 306. More specifically, the first motor 302 is driven to rotate by the guide rail 301, and the first motor 302 and the vertical frame 304 are meshed to make the vertical frame 304 move vertically inside the guide rail 301, so that the sampling operation of water at a fixed depth can be realized in cooperation with the scale line 306.

[0027] The water storage assembly 5 includes a cylinder 501, the cylinder 501 is fixedly mounted on the bottom surface of the horizontal frame 305, a drain port 502 is provided on the right wall of the cylinder 501, a valve 503 is embedded on the surface of the drain port 502, and a water inlet 504 is provided on the bottom surface of the cylinder 501. More specifically, the piston 8 is moved vertically upward inside the cylinder 501 by the driving mechanism 6, so that the water pushes the one-way sealing mechanism 7 open under the action of negative pressure to enter the inside of the cylinder 501. When draining water, the valve 503 is opened, and the piston 8 is moved vertically downward inside the cylinder 501 by the driving mechanism 6, so that the water in the cylinder 501 is discharged to the outside through the drain port 502.

[0028] The driving mechanism 6 includes a second motor 601, the second motor 601 is fixedly mounted on the top surface of the horizontal frame 305, and the second motor 601 is located inside the waterproof cover 4, a screw rod 602 is fixedly mounted on the output end of the second motor 601, a threaded sleeve 603 is threadedly sleeved on the surface of the screw rod 602, and a piston 8 is fixedly mounted on the bottom end of the threaded sleeve 603. More specifically, the screw rod 602 is driven to rotate by the second motor 601, and the screw rod 602 and the threaded sleeve 603 are meshed, so that the piston 8 is driven to move vertically inside the cylinder 501 through the threaded sleeve 603.

[0029] The one-way sealing mechanism 7 includes a sealing plug 701, which is inserted into the water inlet 504. A stepped shaft 702 is fixedly installed on the bottom surface of the sealing plug 701, and the stepped shaft 702 and the cylinder 501 are movably plugged, and a spring 703 is sleeved on the surface of the stepped shaft 702. More specifically, water enters the water inlet 504 under the negative pressure in the cylinder 501 to push the sealing plug 701 to move vertically upward, compressing the spring 703, so that the spring 703 is compressed to achieve water entering the cylinder 501. When the drone body 1 transports water, the sealing plug 701 is plugged into the water inlet 504 under the elastic force of the spring 703 to prevent water leakage in the cylinder 501.

[0030] The surface of the piston 8 is arranged in close contact with the inner wall of the cylinder 501, and the piston 8 is arranged in a sliding manner inside the cylinder 501. More specifically, the inner wall of the cylinder 501 is used to limit and guide the piston 8.

[0031] In summary: after the drone body 1 flies to the sampling water area, the drone body 1 is landed on the water surface so that the float 2 contacts the water surface, and the drone body 1 floats on the water surface due to the buoyancy of the float 2, and the water storage component 5 is moved vertically through the lifting mechanism 3. After the water storage component 5 is inserted to the sampling depth, the driving mechanism 6 drives the piston 8 to move vertically inside the water storage component 5, thereby generating negative pressure in the water storage component 5. Under the action of the negative pressure, water pushes open the one-way sealing mechanism 7 and enters the interior of the water storage component 5 to achieve sampling. After sampling, the drone body 1 takes off to transport the sample.
