The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes a water quality sampling device for environmental testing, comprising a base plate 1, a fixed cavity 2 is installed on the top of the base plate 1, a moving mechanism is arranged inside the fixed cavity 2, a mounting cavity 3 is installed below the fixed cavity 2, a first servo motor 4 is installed on one side of the mounting cavity 3, a winding roller 5 is installed inside the mounting cavity 3, an output end of the first servo motor 4 is connected to one end of the winding roller 5, a connecting rope 6 is arranged on the outer wall of the winding roller 5, a sampling cavity 7 is installed at the bottom end of the connecting rope 6, a mounting plate 8 is installed at the bottom end of the sampling cavity 7, a sampling tube 9 is installed inside the mounting plate 8, and a power mechanism is arranged above the sampling tube 9.

[0020] The power mechanism includes a movable plate 10, a cavity 11, a threaded sleeve 12, a threaded rod 13, a limiting rod 19, a limiting sleeve 20 and a transmission structure. The movable plate 10 is installed inside the sampling cavity 7, and the bottom end of the movable plate 10 is connected to the top of the piston inside the sampling tube 9. The limiting rods 19 are installed on both sides of the sampling cavity 7. The outer wall of the limiting rod 19 is provided with a limiting sleeve 20, and one end of the limiting sleeve 20 is connected to one side of the movable plate 10. The cavity 11 is installed at the top of the sampling cavity 7. The threaded sleeve 12 is rotatably installed inside the cavity 11, and the threaded sleeve 12 is provided with a threaded rod 13 inside. One end of the threaded rod 13 extends to the inside of the sampling cavity 7, and the bottom end of the threaded rod 13 is connected to the top of the movable plate 10. The transmission structure includes transmission teeth 14, a transmission gear 15, a second servo motor 16 and a limiting structure. The transmission teeth 14 are installed on the outer wall of the threaded sleeve 12. Installed inside the cavity 11, the transmission teeth 14 and the transmission gear 15 are meshed with each other, the second servo motor 16 is installed at the top of the cavity 11, the output end of the second servo motor 16 is connected to one end of the transmission gear 15, and the outer wall of the second servo motor 16 is provided with a waterproof shell. When in use, the second servo motor 16 is started to drive the transmission gear 15 to rotate. Since the transmission teeth 14 and the transmission gear 15 are meshed with each other, the transmission teeth 14 are used to drive the threaded sleeve 12 to rotate under the limit of the limit rail 17 and the limit block 18. Since the threaded sleeve 12 is threadedly connected to the threaded rod 13, the threaded rod 13 is used to drive the movable plate 10 to move under the limit of the limit rod 19 and the limit sleeve 20, and then the piston inside the sampling tube 9 is driven to move upward, so as to absorb and sample the water in the target area. The sampling is more convenient and efficient, and the sampling effect is better, thereby greatly improving the practicality of the device when in use.

[0021] The limiting structure includes a limiting rail 17 and a limiting block 18. The limiting rail 17 is installed at the bottom end of the cavity 11. The limiting block 18 is arranged inside the limiting rail 17. One end of the limiting block 18 is connected to the outer side of the threaded sleeve 12. The inner diameter of the limiting rail 17 is larger than the outer diameter of the limiting block 18. A sliding structure is formed between the limiting rail 17 and the limiting block 18. When in use, the threaded sleeve 12 can be limited during rotation by utilizing the mutual cooperation between the limiting rail 17 and the limiting block 18, so that the threaded sleeve 12 is more stable during rotation.

[0022] The moving mechanism includes a third servo motor 21, a screw rod 22 and a screw sleeve 23. The third servo motor 21 is installed on one side of the fixed cavity 2, and the screw rod 22 is installed inside the fixed cavity 2. The output end of the third servo motor 21 is connected to one end of the screw rod 22. The outer wall of the screw rod 22 is provided with a screw sleeve 23. The bottom end of the screw sleeve 23 is connected to the top of the installation cavity 3. When in use, the third servo motor 21 is started to drive the screw rod 22 to rotate, thereby driving the screw sleeve 23 to move, and then driving the sampling cavity 7 to move. By moving the sampling cavity 7 to an appropriate position, the sampling cavity 7 can be driven to perform sampling processing in different areas, thereby greatly improving the versatility of the device when in use.

[0023] A plurality of sampling tubes 9 are arranged inside the mounting plate 8 , and the plurality of sampling tubes 9 are distributed at equal intervals inside the mounting plate 8 . The arrangement of the plurality of sampling tubes 9 allows multiple samples to be collected at one time.

[0024] Working principle: the staff first moves the device to the appropriate position, and then uses the fixing pin to fix the position of the bottom plate 1, and then starts the third servo motor 21 to drive the screw 22 to rotate, thereby driving the screw sleeve 23 to move, and then drives the sampling chamber 7 to move, and moves the sampling chamber 7 to the appropriate position, and then starts the first servo motor 4 to drive the winding roller 5 to rotate, and then uses the connecting rope 6 to drive the sampling chamber 7 to move, so that the sampling chamber 7 enters the water, and then moves the sampling chamber 7 to an appropriate height, and starts the second servo motor 16 to drive the transmission gear 15 to rotate. Since the transmission teeth 14 and the transmission gear 15 are meshed with each other, the sampling chamber 7 is moved to the limit rail. Under the limitation of 17 and the limit block 18, the transmission teeth 14 are used to drive the threaded sleeve 12 to rotate. Since the threaded sleeve 12 is threadedly connected to the threaded rod 13, the threaded rod 13 is used to drive the movable plate 10 to move under the limitation of the limit rod 19 and the limit sleeve 20, and then the piston inside the sampling tube 9 is driven to move upward to absorb and sample the water in the target area. After the sampling is completed, the first servo motor 4 is started to use the winding roller 5 to drive the connecting rope 6 to wind up, drive the sampling chamber 7 to move upward, and then start the third servo motor 21 to drive the sampling chamber 7 to move toward the shore, and start the second servo motor 16 to reverse it to discharge the water inside the sampling tube 9.
