Embodiment 1

[0025] Example one, by Figure 1-4 Provided, a fully automatic large bucket water sampling device, comprising: an installation box 1, the top of the installation box 1 is inserted with a support column 2, the top of the support column 2 is fixedly connected with a mounting plate 3, and the front side of the mounting plate 3 is provided with The sampling rack 4, the bottom of the sampling rack 4 is provided with a fixing slot, and four partitions are arranged in the fixing slot, and the four partitions divide the fixing slot into five sampling chambers, and each sampling chamber is provided with a sampling mechanism;

[0026]The sampling mechanism includes a rotating shaft 5, a mounting block 6, a driving motor 7 and a plurality of sampling components. The rotating shaft 5 is rotatably connected in the sampling cavity, the mounting block 6 is fixedly connected to the bottom end of the rotating shaft 5, and the driving motor 7 is arranged on the sampling frame. 4, and the drive ...

Embodiment 2

[0035] In the second embodiment, on the basis of the first embodiment, two stoppers are symmetrically arranged in the installation cavity, and the stoppers cooperate with the slide plate 20, and two guide rods are symmetrically inserted into the slide plate 20, and both ends of the guide rods are fixed. When connected in the installation cavity, the moving direction of the sliding plate 20 can be limited, so as to prevent the sliding plate 20 from shifting when moving.

Embodiment 3

[0036] Embodiment 3, on the basis of Embodiment 1, a controller is provided on one side of the installation box 1, and the controller is electrically connected with the drive motor 7, the electric telescopic rod 8, the motor 14, the servo motor 26 and the synchronous motor 33, It is convenient for personnel to control the driving motor 7 , the electric telescopic rod 8 , the motor 14 , the servo motor 26 and the synchronous motor 33 .

[0037] working principle:

[0038] When using this sampling device:

[0039] The first step: first control the timer 19, make the timer 19 time for 30 minutes and turn on the ultraviolet sterilization lamp 18, and simultaneously turn on the driving motor 7, so that the rotating shaft 5 drives the installation block 6 and the sampling assembly to rotate, so that the ultraviolet sterilization lamp 18 is rotated. Sterilize the sampling components;

[0040] Step 2: After the sterilization work is completed, push the control handle, so that the ca...

Abstract

The invention discloses a full-automatic large-barrel water sampling device, and relates to the technical field of water quality sampling, the full-automatic large-barrel water sampling device comprises a mounting box, a supporting column is inserted in the top of the mounting box, the top end of the supporting column is fixedly connected with a mounting plate, the front side of the mounting plate is provided with a sampling frame, and the bottom of the sampling frame is provided with a fixing groove; four partition plates are arranged in the fixing groove, the four partition plates divide the fixing groove into five sampling cavities, a sampling mechanism is arranged in each sampling cavity, each sampling mechanism comprises a rotating shaft, a mounting block, a driving motor and a plurality of sampling assemblies, the rotating shafts are rotationally connected into the sampling cavities, and the mounting blocks are arranged in the sampling cavities; and the mounting block is fixedly connected to the bottom end of the rotating shaft. According to the large-barrel water sampling device, the problem that time and labor are wasted in sampling work due to the fact that most of existing large-barrel water sampling devices need manual sampling and continuous manual cover taking is solved, and the effect that multiple barrels of water can be automatically sampled and the covers can be automatically taken at the same time is achieved.

Description

technical field [0001] The invention relates to the technical field of water quality sampling, in particular to an automatic large-barrel water sampling device. Background technique [0002] In the large bucket of water, it is necessary to detect Pseudomonas aeruginosa, Streptococcus faecalis, and Clostridium perfringens in the water quality of the large bucket of water. When detecting Pseudomonas aeruginosa: filter membrane method is used, and 250 mL of water sample is used Filter through a filter with a pore size of 0.45 μm and transfer the filter to CN agar medium. The filtration operation is carried out on a class 100 clean bench. First, use sterile tweezers to pick up the edge of the sterile filter, place the rough side up on the sterilized filter bed, fix the filter, and filter 250 mL of water sample or diluent through a filter with a pore size of 0.45 μm, then Stick the filtered membrane on the prepared CN agar plate, lay it flat and avoid trapping air bubbles betwe...
