The lower inner side of the water inlet head 5 is connected to the outer side of the ring frame 6. A sealing top plate 7 is movably installed on the top of the ring frame 6. A connecting structure is provided between the water inlet head 5 and the sealing top plate 7. The lower left side of the rigid bend 3 is connected to the bottom side of the water inlet head 5. The outer side of the lower left part of the rigid bend 3 is connected to the inner side of the anti-slip contact sleeve 4. The top side of the sampling bottle 9 is connected to the bottom side of the sleeve opening 8. The inner side is detachably connected to the outer side of the anti-slip contact sleeve 4. In use, the sampling bottle 9 is fitted onto the outer side of the anti-slip contact sleeve 4 through the sleeve opening 8. Then, the movable sleeve 2 is slid vertically on the outer side of the scale rod 1. According to the scale display of the scale rod 1, it is positioned appropriately and fixed by the fixing structure. Then, the entire device is extended downwards towards the water area to be tested. The sealing top plate 7 and the ring frame 6 are closed to keep the inside of the sampling bottle 9 empty. The counterweight 11 is connected by the connecting frame 10 to make the center of gravity of the device close to the middle to avoid overall displacement. After the sampling bottle 9 is in position, the operator operates the connecting structure to open the sealing top plate 7 relative to the ring frame 6. Water can enter through the water inlet head 5, be introduced into the sampling bottle 9 through the anti-slip contact sleeve 4 for collection, and then the device is taken out. The sleeve opening 8 of the sampling bottle 9 is removed from the outer side of the anti-slip contact sleeve 4 for online testing of the sampled water.

[0016] The fixed structure includes an anti-slip contact strip 12, a tightening sleeve 13, a tightening screw 14, and a tightening handle 15. The front middle of the movable sleeve 2 is connected to the rear side of the tightening sleeve 13. The inner wall of the tightening sleeve 13 is screwed to the outer wall of the tightening screw 14. The front side of the tightening screw 14 is connected to the rear middle of the tightening handle 15. The front middle of the scale rod 1 is connected to the rear side of the anti-slip contact strip 12. The movable sleeve 2 can slide vertically on the outside of the scale rod 1. After it is in position, the tightening handle 15 can be turned to rotate the tightening screw 14. The tightening screw 14, after being screwed into the tightening sleeve 13, can act inward to contact and tighten the anti-slip contact strip 12 at that position on the outside, thereby improving stability.

[0017] The connecting structure includes a top frame 16, an inner groove 17, a connecting spring 18, a connecting rope 19, and a pull ring 20. The middle of the left and right sides of the top of the water inlet head 5 is connected to the left and right sides of the bottom of the top frame 16. The outer side of the top of the inner top of the top frame 16 is connected to the outer side of the top of the sealing top plate 7 via the connecting spring 18. The middle of the top side of the sealing top plate 7 is connected to the bottom side of the connecting rope 19. An inner groove 17 is provided in the middle of the top side of the top frame 16. The connecting rope 19 extends outward through the inner groove 17, and a pull ring 20 is connected to the other side of the connecting rope 19. Under the connection of the top frame 16, the elastic action of the connecting spring 18 can press the sealing top plate 7 tightly against the top of the ring frame 6 for sealing. When the pull ring 20 is pulled, the connecting rope 19 can move, acting on the sealing top plate 7 to overcome the lifting of the connecting spring 18, so that a gap is created between the sealing top plate 7 and the ring frame 6, which facilitates water intake.

[0020] In summary, when using an online water quality monitoring sampling device, the sampling bottle 9 is fitted onto the outside of the anti-slip contact sleeve 4 via the sleeve 8. Then, the movable sleeve 2 is slid vertically outside the scale rod 1, positioning it according to the scale markings. The tightening handle 15 is then turned, causing the tightening screw 14 to rotate. The tightening screw 14, through its engagement with the tightening sleeve 13, acts inward to contact and tighten the anti-slip contact strip 12 at that position. The entire device is then extended downwards towards the water area to be tested. Connected to the top frame 16, the connecting spring 18 elastically presses the sealing plate 7 against the top of the ring frame 6, sealing the sampling bottle 9 and keeping the inside empty. The connecting frame 10... The connection of the counterweight 11 keeps the center of gravity of the device in the middle, preventing overall displacement. After the sampling bottle 9 is in position, the operator can pull the ring 20 to move the connecting rope 19, which acts on the sealing top plate 7 to overcome the connecting spring 18 and lift it, so that the sealing top plate 7 opens relative to the ring frame 6. Water can enter through the water inlet 5, pass through the anti-slip contact sleeve 4 and be collected in the sampling bottle 9. Afterwards, the device can be removed, and the sleeve 8 of the sampling bottle 9 can be removed from the outside of the anti-slip contact sleeve 4 for online testing of the sampled water. In addition, the scale bar 21 can display the scale of the sampling bottle 9, which facilitates accurate control of the water volume. The sampling bottle 9 can be moved by holding the handle 22, which improves convenience.
