[0037] The opening and closing assembly comprises the opening and closing plate 19, the fixed plate 20 and the waterproof motor 21. The opening and closing plate 19 is rotatably connected to one side of the fixed plate 20, and is used to control the sampling of the sampling barrel 15. The outer wall of the fixed plate 20 is fixedly connected to the inner wall of the sampling barrel 15. The waterproof motor 21 is fixedly connected to one side of the fixed plate 20, and provides power for the opening and closing of the opening and closing plate 19. One side of the opening and closing plate 19 is fixedly connected to the output end of the waterproof motor 21. The weight increasing assembly comprises the weight increasing ring 17 and the conical barrel 18. The inner wall of the weight increasing ring 17 is fixedly connected to the outer wall of the sampling barrel 15, so as to increase the weight of the sampling barrel 15. One end of the conical barrel 18 is fixedly connected to one end of the sampling barrel 15, so as to increase the weight of the sampling barrel 15. The winding assembly comprises the rope roller 8 and the hemp rope 10. One end of the rope roller 8 is fixedly connected to the inner wall of the box body 1, and is used to wind the hemp rope 10. One end of the hemp rope 10 is fixedly connected to the outer wall of the rope roller 8. The driving assembly comprises the driven gear 4, the driving gear 5 and the driving motor 6. One end of the driven gear 4 is fixedly connected to one end of the cable roller 7 and the rope roller 8. One end of the driving gear 5 is fixedly connected to the inner wall of the box body 1. The outer wall of the driving motor 6 is fixedly connected to the outer wall of the box body 1, so as to provide power for the equipment.

The cable roller 7 and the rope roller 8 are arranged in parallel array on the inner wall of the box body 1.

[0040] Specifically, the supporting rod 25 has high practicability. When it is not needed, it can be more conveniently stored in the specially provided receiving groove 23. The receiving groove 23 provides a safe storage place for the supporting rod 25, and the limiting groove 27 plays a crucial role in firmly fixing the connecting column 26 so that it is not easy to shake in various situations. In this way, the overall structure can be effectively prevented from becoming loose, and the stability and reliability of the entire device are ensured. Whether in a calm environment or in a situation of slight vibration, the limiting groove 27 can always perform its duties and provide firm support for the connecting column 26, so that the entire structure remains tight and firm.

[0041] Working principle: in the process of using the water resource sampling device for water conservancy projects, first set the required sampling depth on the display screen 3, then start the equipment, at this time the driving motor 6 drives the driving gear 5, the driving gear 5 drives the driven gear 4, then drives the cable roller 7 and the rope roller 8 to rotate, so that the sampling barrel 15 reaches the required depth of water, when reaching the required depth, the waterproof motor 21 starts to drive the opening and closing plate 19 to rotate, so that the water sample of the required depth enters the inside of the sampling barrel 15, when the water volume is enough, the waterproof motor 21 drives the opening and closing plate 19 to close, then the driving motor 6 drives the sampling barrel 15 to lift, at this time the operator can take out the water sample in the sampling barrel 15 and take it to the laboratory for testing. When the equipment is not needed, the driving motor 6 can be used to lift the sampling barrel 15 completely, then the connecting column 26 is pulled out of the limiting groove 27, the supporting rod 25 is stored in the receiving groove 23, then the folding arm 13 is folded downward through the rotating shaft 22, then the lifted water barrel is fixed on the conducting column 12, and the storage of the entire equipment is completed, which is convenient for next use.

[0042] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
