DETAILED DESCRIPTION

[0022] Please refer to the attached Figures 1-4 It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] The utility model provides a hydrogeological water quality sampling device. Before use, the slide cylinder 8 is located at the lowest position in the rectangular cylinder 7. At this time, the sealing plug 17 blocks the circular hole of the cover body 16, and the pointer points to the position just above. When using the device, after the device is pushed to the location to be measured by the vehicle body 5, the sampling cylinder 18 is screwed on the cover body 16, and a counterweight block 6 of corresponding weight is selected according to the depth required for sampling. The counterweight block 6 is clamped and installed at the lower end of the rectangular cylinder 7, and the motor 13 is started. The motor 13 drives the gear 2 4 to rotate, and the gear 2 4 drives the gear 1 3 engaged therewith to rotate, and the gear 3 drives the reel 10 to rotate. When the reel 10 rotates, the rope 2 starts to pay out the line. When a certain length of line is paid out, the sampling structure is put into the sampling area. Under the action of the counterweight block 6, the sampling structure can slide vertically downward, and the rope 2 is always in a straight state. The buoyancy of the water will not cause the sampling structure to fall to an inaccurate depth. Since the gear 1 rotates one circle, the line is paid out by 1m, and the pointer can assist in recording The number of revolutions of gear 1 3 is adjusted. After the sampling structure is lowered to an appropriate depth as required, the motor 1 3 is turned off and the motor 2 1 is started. The rotation of the motor 2 1 drives the screw 9 to rotate. The rotation of the screw 9 drives the slide 8 to slide upward along the rectangular tube 7. The slide 8 drives the slider 14 to slide upward along the slide groove. The slider 14 drives the sealing plug 17 to slide upward and separate from the cover 16 through the support rod 15. The water flows into the sampling tube 18 through the circular hole. After standing for a while, when the water flows into the sampling tube 18, it is started again. Motor 2 1, motor 2 1 reverses to drive the sealing plug 17 to seal the cover body 16 again, start motor 13 again, motor 13 reverses to lift the sampling structure, unscrew the sampling cylinder 18, and pour the water sample in the sampling cylinder 18 into a dedicated sample collection tube. After cleaning and drying the sampling cylinder 18, screw it on the cover body 16 again (you can also prepare multiple sampling cylinders 18), repeat the above steps, you can sample water quality at different depths, and conduct a more accurate test of the water quality.
