Description

Technical Field

[0001] The utility model relates to the technical field of sampling, in particular to a water potential stratification sampler for a mountain river. Background Art

[0002] River water sampling is a process of collecting representative water samples from water bodies to test various specified water quality characteristics. The main purpose of sampling and testing is to determine the relevant physical, chemical, biological and radioactive parameters. It can be used to evaluate river water quality, determine the use and adaptability of river water; evaluate the impact of the accumulation and release of pollutants in riverbed sediments on aquatic organisms and sediments; study the impact of pumping, river water regulation and river water transportation on the physical and chemical properties of river water and aquatic organisms, etc.

[0003] At present, due to the relatively complicated road conditions in mountainous areas, in order to facilitate sampling of mountain rivers, people generally carry relatively light samplers for sampling. Such samplers are mostly composed of sampling bottles and ropes. When sampling, the sampling depth is determined by the rope. However, due to the different flow velocities of water at different depths in the river, the rope is very likely to be in a tilted state during the sampling process, making the depth judgment inaccurate. At the same time, if it is necessary to sample water at different depths at the same sampling point, multiple operations are required, which is very inconvenient. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 4 As shown, it relates to a mountain river water potential stratification sampler, including a handle 1, a telescopic rod 2 is fixedly connected to the bottom of the handle 1, a plurality of sampling bottles 3 are arranged below the telescopic rod 2, and the movable end of the telescopic rod 2 is fixedly connected to the top sampling bottle 3, and both ends of the plurality of sampling bottles 3 are fixedly penetrated with electromagnetic valves 5. After the sampling bottles 3 enter the water, the two electromagnetic valves 5 can be opened so that the two ends of the sampling bottles 3 are opened. At this time, water can naturally flow into the sampling bottles 3.

[0023] Except for the sampling bottle 3 at the bottom, the bottoms of the other multiple sampling bottles 3 are fixedly connected to the plastic shell 4, and the multiple plastic shells 4 are installed with telescopic components, and the movable ends of the telescopic components are fixedly connected to the adjacent sampling bottles 3. The multiple telescopic components include a driving block 6, and the driving block 6 is arranged outside the plastic shell 4. One end of the driving block 6 is fixedly connected to a screw rod 9, and the screw rod 9 extends through the outer wall of the plastic shell 4 to the inside and is rotatably connected thereto. The outer surface of the screw rod 9 is threadedly sleeved with a slider 13, and the slider 13 is slidably connected to the plastic shell 4. The inner top of the plastic shell 4 is fixedly connected to a fixed block 8 The fixed block 8 and the bottom of the slider 13 are rotatably connected to the scissor-type telescopic frame 11, and the bottom of the scissor-type telescopic frame 11 is rotatably connected to the connecting block 7 and the movable block 12. The bottom of the connecting block 7 is fixedly connected to the long strip 10, and the movable block 12 is slidably connected to the long strip 10. The long strip 10 is fixedly connected to the adjacent sampling bottle 3. The driving block 6 is rotated, and the driving block 6 drives the screw rod 9 to rotate. The screw rod 9 drives the slider 13 to approach the fixed block 8, so that the scissor-type telescopic frame 11 extends, thereby pushing the long strip 10 to move, and then pushing the two sampling bottles 3 away from each other, and the distance between the two sampling bottles 3 can be adjusted.

[0024] A winding wheel 18 is rotatably installed on the inner wall of one side of multiple plastic shells 4, and transmission components are installed between the multiple winding wheels 18 and adjacent telescopic components respectively. The multiple transmission components all include a pinion 14, and the pinion 14 is fixedly sleeved on the outer surface of the screw rod 9. The outer surface of the pinion 14 is meshed with a large gear 16, and the large gear 16 is fixedly sleeved on the outer surface of the winding wheel 18.

[0026] Working principle: When sampling, first determine the sampling depth of multiple sampling points, then adjust the spacing between the sampling bottles 3, rotate the drive block 6, the drive block 6 drives the screw rod 9 to rotate, the screw rod 9 drives the slider 13 close to the fixed block 8, so that the scissor-type telescopic frame 11 extends, thereby pushing the long strip 10 to move through the connecting block 7 and the movable block 12, and then push the two sampling bottles 3 away from each other until the spacing reaches the set value, and at the same time, the screw rod 9 will drive the small gear 14 to rotate when rotating, and the small gear 14 can drive the winding wheel 18 to rotate through the large gear 16, and the winding wheel 18 releases the first wire 17, and so on and so forth until the position adjustment of all sampling bottles 3 is completed, and then choose whether to adjust the telescopic length of the telescopic rod 2 as needed, and then insert the whole into the water through the handle 1. After stabilization, open the sampling bottle 3 through the solenoid valve 5, and the water in the river naturally flows into the sampling bottle 3. After a period of time, the solenoid valves 5 at both ends of the sampling bottle 3 are closed at the same time, and then the whole is taken out to complete the sampling.
