Abstract

The invention discloses a depth-fixed periphery comprehensive water sampler. The depth-fixed periphery comprehensive water sampler comprises a water sampler main body, a first telescopic rod, a sampling pipe and a transmission device, wherein a fixed base is arranged at the left side of the upper end of the water sampler main body, a depth measuring bar is arranged at the upper end of the fixed base, a second telescopic rod sheathes the upper end of the first telescopic rod, a third telescopic rod sheathes the upper end of the second telescopic rod, eight water inlet pipes distributed in a ring array are arranged at the periphery of the bottom of the sampling pipe, a piston is arranged inside the sampling pipe, a sliding column is fixed at the upper end of the piston by virtue of a connecting column, a rotating shaft is arranged on the transmission device, a gear is fixed at the front end of the rotating shaft, a second conical tooth is fixed at the other end of the rotating shaft, a first conical tooth is meshed with the upper end of the second conical tooth, and a rotary inner rod is fixed at the upper end of the first conical tooth. The depth-fixed periphery comprehensive watersampler disclosed by the invention has the advantages that a unidirectional liquid inlet valve is arranged on each water inlet pipe, water leakage when the water sampler is lifted out of water is avoided, water sampling from the periphery on the same water layer is realized, and sampling is reasonable and accurate.

Description

technical field [0001] The invention relates to a water collecting device, in particular to a comprehensive water collecting device with fixed depth around. Background technique [0002] Water collector, the general term for seawater sample collection equipment. Water buckets are used to collect sea surface water samples, and Nansen water collectors, multi-bottle (or multi-bag) water collectors and spherical cap type water collectors are used to collect water samples of various layers below the sea surface. In addition, there are marine microbial water collectors. In order to meet the needs of sampling work such as marine chemistry, there are two types of instruments for collecting different deep seawater samples: surface seawater collectors and deep seawater collectors. The former usually uses enamel barrels or other barrels that do not chemically interact with seawater. The latter is a A cylindrical barrel with a valve or a cover, which can be closed in an upside-down ma...
