[0028] The water inlet opening assembly 8 comprises a resisting jack 801 which is arranged on the side of the top end of the sampling cylinder body 1, the outer side of the resisting jack 801 is provided with an outer wall connecting seat 802, two limiting connecting rods 803 are vertically arranged on the outer wall connecting seat 802, the side of the outer wall connecting seat 802 is provided with a resisting push plate 804, the two ends of the limiting connecting rod 803 penetrate through the resisting push plate 804, a resisting plug 805 is inserted in the resisting jack 801, the end of the resisting plug 805 is connected with the middle part of the resisting push plate 804 through a pushing connecting rod 806 which is arranged, the limiting connecting rod 803 is sleeved with a resisting spring 807, one end of the resisting spring 807 is connected with the resisting push plate 804, the other end of the resisting spring 807 is connected with the rod body of the limiting connecting rod 803, and the middle part of the side of the resisting push plate 804 is provided with a rope connecting ring 808.

[0029] Embodiment two: the difference between this embodiment and embodiment one is that the top closing cover 701 is connected with the top of the sampling cylinder body 1 through threads.

[0030] Make the connection between the top closure cover 701 and the sampling cylinder body 1 more convenient.

[0031] Embodiment three: the difference between this embodiment and embodiment one is that the top side of the water inlet closure plate 705 is provided with a connecting block.

[0032] Make the user pull the reset of the water inlet closure plate 705 more convenient.

[0033] Embodiment four: the difference between this embodiment and embodiment one is that the resisting plug 805 extends through the resisting insertion hole 801 to the bottom side of the water inlet closure plate 705.

[0034] Make the resisting plug 805 resist the side of the water inlet closure plate 705 under the elastic resistance of the resisting spring 807, avoid the water inlet closure plate 705 rotating under the rebound force of the torsion spring 707, and open the water inlet 702.

[0035] In this embodiment, because the existing water quality test sampling cylinder is a simple water storage cylinder in actual use, when the user needs to sample different water layers, the surface water is easily first into the sampling cylinder, thereby reducing the sampling accuracy and causing large errors in subsequent sample detection.

[0036] In summary, when the user needs to sample a specified depth water layer, the user first needs to slide the marker ring 11 on the pull rope 10 to the specified depth position to facilitate the user to judge the descending depth of the sampling cylinder body 1 into the water, and tie the rope on the rope connecting ring 808 in the water inlet opening assembly 8. At this time, the resisting plug 805 provided at the end of the connecting rod 806 is inserted in the resisting insertion hole 801, and extends through the resisting insertion hole 801 to the inner wall of the sampling cylinder body 1 under the rebound force of the resisting spring 807, that is, the bottom side of the water inlet closure plate 705, which can resist the bottom side of the water inlet closure plate 705, so that the water inlet closure plate 705 will not be opened under the water pressure and the rebound force of the torsion spring 707, and be in a closed state of the water inlet 702, when the sampling cylinder body 1 is lowered to the sampling water layer.

[0037] At this time, the user can pull the rope tied to the rope connecting ring 808 sharply, so that the rope connecting ring 808 drives the resisting plug 805 to retract into the resisting insertion hole 801 through the connecting rod 806, so that the end of the resisting plug 805 no longer resists the end of the water inlet closure plate 705, and the water inlet closure plate 705 rotates under the combined action of water pressure and the rebound force of the torsion spring 707, thereby opening the water inlet 702, so that the sampling cylinder body 1 located at the specified water layer position is filled with the required water through the water inlet 702.

[0038] The water filled in the sampling cylinder 1 is pulled out of the water through the pull rope 10, and by removing the water stop clamp 5, the sampling water in the sampling cylinder 1 can be discharged into the collection bottle through the drainage hose 4 for preservation. The device can prevent the surface water from entering the sampling cylinder 1 in advance before the sampling cylinder 1 reaches the designated position, so that the sampling cylinder 1 can sample the water after reaching the designated water layer, the sampling sample is more accurate, thereby being beneficial to subsequent water quality detection.
