Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a device for static extraction and sub-packaging of surface water samples. Background Art

[0002] Water quality detection is a process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality status. The monitoring scope is very wide, including unpolluted and polluted natural waters and various industrial wastewaters, etc. The main monitoring items can be divided into two categories. One is the comprehensive indicators reflecting the water quality status, and the other is some toxic substances. In addition to the above monitoring items, sometimes the flow velocity and flow rate need to be measured.

[0003] With the increasing attention to environmental protection, it is necessary to manage and monitor some urban water, rivers or groundwater. Generally, when monitoring surface water, a part of the sample needs to be extracted first, and then statically sub-packaged. The static sub-packaging of surface water usually follows relevant standards and specifications. Specifically, after the surface water sample is collected and arrives at the laboratory, the water sample is placed in a suitable environment and left to stand for 30 minutes. Then, the non-settled part of the water sample on the upper layer is transferred and sub-packaged into multiple clean small containers.

[0004] However, this method is easily affected by factors such as temperature and light during the standing process, which may cause changes in the properties of the water sample. If there is no good sealing measure, pollutants in the air may enter the container, thus affecting the test results. At the same time, after the standing is completed and sub-packaged, when transferring the supernatant of the water sample into the sub-packaging container, manual quantitative sub-packaging is required. Manual operation often shakes the just-settled solid sediment, resulting in poor standing sedimentation effect, so that the sediment is sub-packaged into the container during the sub-packaging process, thus affecting the test results; and traditional manual sub-packaging sub-packages multiple water samples with different volumes at one time, and the sub-packaged volume is often not accurate enough, which is easy to cause errors, and the manual sub-packaging time is long and the efficiency is low.

[0005] In view of this, this application proposes a device for static extraction and sub-packaging of surface water samples with a relatively stable and clean environment, and equipped with automatic, timing, quantitative and positioning functions. Summary of the Utility Model

Thus, by connecting the floating plate that can descend with the water level and the graduated conduit, the water sample collected can always be the water at a fixed position under the supernatant liquid surface.

[0025] In this embodiment, the control assembly includes a main unit 2, a main controller is installed in the main unit, the main controller is electrically connected to a sampling pump, and the liquid outlet of the sampling pump is connected to a sub-sampling needle 24 through a water delivery pipe; and a control switch 21, a control panel 23, and a timer 22 are provided on the surface of the main unit 2, and the control switch 21, the control panel 23, and the timer 22 are electrically connected to the main controller. Thus, the control switch 21 can realize the automatic extraction of the supernatant water sample, and the timer 22 can realize the static timing reminder; the control panel 23 can freely set the flow rate to control the amount of the sub-packed sample, can freely set the sub-packing position of the sub-sampling needle, and can prompt the completion of the sub-packing; the sub-sampling needle 24 extracts a quantitative sample and cooperates with the sub-packing track 34 to be sub-packed at a fixed point into the sub-packing bottle 32 according to the sub-packing position set by the control panel 23.

[0026] In this embodiment, the sub-packing assembly 3 includes a multi-hole sub-packing tray 31, a sub-packing bottle 32 is detachably connected to the multi-hole sub-packing tray 31, and the sub-packing bottle 32 is matched with the sub-sampling needle 24; and a weighing plate 33 is provided at the bottom of the multi-hole sub-packing tray 31, a slide rail 34 is provided on the weighing plate 33, a sliding member is connected to the slide rail 34, and the sliding member is electrically connected to the main controller. Specifically, the multi-hole sub-packing tray 31 of the sub-packing assembly 3 has a total of 12 sub-packing grids for placing sub-packing bottles 32 of multiple specifications, which are 500 mL, 250 mL, 200 mL, 100 mL, 50 mL, and 25 mL with the maximum capacity, and there are two of each capacity.
