Abstract
The invention relates to water harvesting equipment, in particular to a fixed-depth water harvesting device and a water harvesting method thereof. The water harvesting device includes a scale rope, a weight, a water harvesting cylinder and a lead fish, and the water harvesting cylinder includes an end cover, a cylinder body, and a scale. Rope fixing parts, opening and closing mechanism and water discharge parts, scale rope fixing parts include upper and lower fixing blocks and compression screws; opening and closing mechanism includes elastic parts, end cover rope buckle, rope buckle, stick body, U-shaped block, limit Blocks, straight pins, folded pins and springs; the method is: before water collection, connect the lead fish, water collection tube and weight on the scale rope in sequence, and open the end cover of the water collection tube; when collecting water, put the water collection tube down After reaching the required depth, manually release the heavy hammer, hit the opening and closing mechanism, make it release the rope buckle, and close the water collection cylinder; finally, lift the water collection cylinder with the help of the on-board winch on the survey ship to complete the water collection, and the water outlet is controlled by the water release part. Water sample analysis. The invention has the advantages of rapid water collection, easy manufacture, multi-layer water samples and the like.
Description
technical field [0001] The invention relates to water harvesting equipment, in particular to a fixed depth water harvesting device and a water harvesting method thereof. Background technique [0002] Microbial analysis, suspended particulate matter capture and chemical composition identification in water bodies are important contents for human beings to understand and study rivers, lakes and oceans. The first condition for this analysis and research is to obtain their water body samples. Surface water is easy to obtain, but it is difficult to collect water samples at fixed depths. The existing fixed-depth water collection device has complicated structure, high price and difficult operation. Contents of the invention [0003] The object of the present invention is to provide a fixed-depth water mining device and a water mining method thereof. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The fixed-depth wate...
