Portable combined field surveying water well water sampler

Abstract

The invention relates to a portable combined field surveying water well water sampler.The portable combined field surveying water well water sampler comprises a manual lifter installed on a support, the support installed at the lower portion of the manual lifter and a water taking cup connected with a flexible rule, wherein the manual lifter comprises a housing, a hand-cranking arm, the flexible rule and two gears.The two gears are installed inside the housing through gear shafts, the hand-cranking arm is connected with one gear shaft, the flexible rule is installed on the gears, and the housing is provided with a flexible rule inlet-outlet.The water taking cup comprises an upper lid, a cup body, a connecting ring, a plurality of steel wire columns, a funnel, a water drain valve switch and a lower lid, wherein the upper lid is connected with the flexible rule through the connecting ring, the funnel is arranged at the bottom of the cup body, the water drain valve switch is connected at a funnel opening, and the steel wire columns are arranged on an upper layer of the cup body.During field surveying, the portable combined field surveying water well water sampler can be rapidly assembled for work implementation, saves time and labors, is simple and convenient to operate, improves the field surveying efficiency and also reduces the surveying costs.The water sampler can be dismounted when being not used, can be put into a bag or a tool box and is convenient to carry.

Description

technical field [0001] The invention relates to a clean water depth-fixing sampler, in particular to a portable combined well water sampler for field investigation. Background technique [0002] The prior art SQY-1 hydrological water well fixed depth sampler has an effective length of 700mm, a maximum outer diameter of 90mm, and a mass of about 2kg. The water container is made of plexiglass material, and the maximum water intake volume at one time is about 2500ml, which is suitable for diameter >; For all well holes of 100mm, use method: before the SQY-1 fixed-depth sampler is lowered into the well hole, pre-determine the depth of the aquifer to be sampled, and accurately measure the length of the steel wire rope for pulling the sampler, and then pull up the pull rod. The pull rod is locked on the weight automatic unlocker through the hanging ring, at this moment the compression spring is compressed, the rubber stopper fixed on the pull rod moves up, and the upper and low...
