Embodiment Construction
[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] like figure 1 A marine environment water sample collector as shown includes a sampling cylinder 1 and a manual valve-type sealing mechanism fixed on the upper end of the sampling cylinder. A counterweight structure is fixed at the lower end of the cylinder. The counterweight structure includes a fastening flange 34 fixed on the outer edge of the lower end of the sampling cylinder, a counterweight block 35 and a bottom plate 36. The counterweight block is placed on the bottom plate, and the counterweight block is fastened by the flange. The upper connecting bolts 37 distributed along the circumference are fastened between the bottom plate and the sampling cylinder; the manual valve sealing mechanism includes a valve seat 3, a poppet valve 4, a guide pipe 5 and a lifting rod 6 (such as figure 2The valve seat is located at the upper end of ...

The present invention disclosed a marine environment water sample collector, including the sample cylinder and manual valve sealing mechanism. The manual valve sealing mechanism includes valve seats, cone valves, guide pipes and lifting rods.The upper end of the guide pipe is exposed from outside the valve seat, the lower end of the guide pipe extends into the cone valve, and the gap between the lifting rod and the guide pipe is coordinated.There is a scaled rope outside the cover and connecting; the guide pipe located in the cone valve is equipped with a card bead hole, a card beads in the card bead hole, the lower part of the lift rod is equipped with a ring -shaped card beads,The beads with the bead card; the upper part of the tone rod in the guide pipe is equipped with a spring seat, and the lift rod jacket between the seal end cover and the spring seat is equipped with a spring.The invention is convenient to operate, is not restricted by on -site conditions, is stable and reliable, has good sealability, flexible use, and can achieve the advantages of fixing in -depth sampling.
Description
technical field [0001] The invention relates to a water sample collection device, in particular to a marine environment water sample collector. Background technique [0002] When monitoring the marine environment, marine water quality monitoring is one of the important monitoring items. The main testing items for marine water quality monitoring include salinity, heavy metals (mercury, cadmium, chromium, etc.), total phosphorus, total nitrogen, suspended solids, and transparency. Before the detection of seawater, it is necessary to collect water samples, that is, sampling. [0003] The current sampling methods mainly include buckets, conventional acrylic or glass water sample collectors, etc. It is very inconvenient to use buckets for sampling, and can only collect superficial water samples; The water is directly fed from the bottom, the water sample cannot be collected at the required depth, and the sealing is not good. [0004] In addition, the application publication nu...
