The working principle of the invention is as follows:
1) When the sampler is placed in the sampling water area, the sampling barrel unit 4 descends, water enters the sampling barrel body 402 from the third water inlet and outlet hole 301 on the bottom plate 3, the second water inlet and outlet hole 201 on the control box 2 and the first water inlet and outlet hole 101 on the top plate 1 in sequence, and is discharged from the upper part of the sampling barrel body 402; when the sampling barrel unit 4 ascends, the flip cover 4026 above the sampling barrel body 402 is opened, water enters the sampling barrel body 402, and then flows out from the through hole at the bottom to be discharged from the first water inlet and outlet hole 101 on the top plate 1, the second water inlet and outlet hole 201 on the control box 2 and the third water inlet and outlet hole 301 on the bottom plate 3 in sequence.
2) In the descending process of the sampler, the pressure sensor 13 and the acceleration sensor 14 respectively perform real-time dynamic detection on the water pressure and the running direction of the sampler device, the pressure sensor 13 and the acceleration sensor 14 provide detected electric signal analog quantities for the microchip control processing unit to perform AD conversion, and the microchip control processing unit performs maximum water depth judgment and calculation on layered point positions of each measuring point through an automatic control program.
3) When the sampler is put into water and descends from the water surface, the flip cover 4026 is always in an open state, the movable cover 4021 is always in a state of being jacked up by the buoyancy block 4022, and the output end of the electric push rod 9 is clamped into the annular groove at the bottom end of the thimble 4023, so that the thimble 4023 is clamped, and the buoyancy block 4022 is prevented from falling; meanwhile, water in the external water area enters from the lower part of the sampler and flows out upwards from the top of the sampling barrel body 402; when the sampler ascends from underwater to water, the microchip control processing unit monitors the position of a measuring point in real time, when the sampler reaches the measuring point position, the microchip control processing unit triggers a control action instruction to enable the output end of the electric push rod 9 to be recovered, at the moment, the flip cover 4026 seals the top of the sampling barrel body 402 under the impact of water flow, the flip cover 4026 pushes the movable cover 4021 to move downwards through the linkage rod 4024 to block the through hole at the bottom of the sampling barrel body 402, so that the water body inside the sampling barrel body 402 does not circulate, at the moment, the sampler is in an ascending state, so that the water flow rate outside the sampling barrel body 402 is greater than the water flow rate inside, the pressure outside the sampling barrel body 402 is smaller than the internal pressure, and then the buoyancy block 4022 cannot jack the movable cover 4021, so that the water body of the measuring point can be reserved inside the sampling barrel body 402, and the sampling of the measuring point is completed; then when the sampler rises to other measuring points, the control circuit board 8 will control the electric push rod 9 below the corresponding sampling barrel body 402 to retract to the output end, and the fixing of the buoyancy block 4022 is canceled so that the corresponding sampling barrel body 402 is closed, thereby completing the collection of water samples of all measuring points on a vertical line; after the sampler discharges water, because the buoyancy block 4022 is located below the movable cover plate 4021, and the movable cover plate 4021 is attached to the bottom of the inner side of the sampling barrel body 402, the buoyancy block 4022 is located outside the sampling barrel body 402, and the movable cover plate 4021 cannot be jacked up, so that the sampling barrel body 402 is still in a closed state.
4) When the sampler is put into water, the floating ball liquid level trigger switch 10 immediately turns on the battery pack 11 to supply power to the sampler, so that the sampler is in a working state.
The above examples are provided for illustrating the preferred embodiments of the present invention and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art to the technical solution of the present invention should fall within the scope of protection defined by the claims of the present invention without departing from the principle and spirit of the present invention.
