[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figure 1-5 The utility model provides a technical solution: a portable sewage sampling device for environmental detection, comprising an outer cylinder 1 and a liquid storage cylinder 5, wherein the inner cavity of the outer cylinder 1 is penetrated by a liquid suction tube 2, and two groups of stoppers 3 and a rotating plate 4 are respectively sleeved on the outer side of the outer cylinder 1, and the rotating plate 4 rotates between the two groups of stoppers 3;

[0021] Liquid storage cylinders 5 are installed at equal intervals on the circumference of the bottom of the rotating plate 4, and liquid guide holes 42 are opened through the outside of the outer cylinder 1, and the liquid guide holes 42 extend to the inner diameter of the rotating plate 4;

[0022] The bottom end of the pipette 2 can be extended into the sampled sewage, and the sewage can be sucked into the pipette 2 by installing a pump body near the top of the outer cylinder 1, and can be introduced into the liquid storage cylinder 5 for storage through the bottom end of the pipette 2. The working technical scheme of the pipette 2 in the sewage sampling device is the prior art and will not be described in detail here;

[0023] A plurality of groups of liquid storage cylinders 5 can be installed in the corresponding threaded openings 43 at the bottom of the rotating plate 4 by threads. When sampling sewage at different depths in layers, the rotating plate 4 can be rotated clockwise ninety degrees in sequence, so that the ends of the pipette tubes 2 passing through the outer wall of the rotating plate 4 are respectively connected to the liquid guide holes 42 at the tops of the four groups of liquid storage cylinders 5 by magnetic attraction. Thus, the sewage at different depths at the fixed point can be extracted and collected in layers into the corresponding four groups of liquid storage cylinders 5, realizing the one-time sampling and collection of sewage at different depths one by one, without the need to frequently disassemble and replace the liquid storage cylinders 5, thereby improving the efficiency of sewage fixed-point sampling and making the operation more convenient.

[0024] Among them, handles 11 are respectively installed on both sides of the top of the outer cylinder 1, and a bottom plate 12 is fixedly installed on the bottom of the outer cylinder 1. The outer cylinder 1 can be stably supported at the environmental detection sewage collection point through the bottom plate 12.

[0025] Among them, scale marks 31 are opened at equal intervals on the circumferential edge of the stopper 3 located at the top of the rotating plate 4, and a pointer 41 is set on the circumference of the top of the rotating plate 4. One end of the pointer 41 and one group of scale marks 31 are located in the same mid-vertical plane. By rotating the annular rotating plate 4, the pointer 41 on the top of the rotating plate 4 can correspond one by one to the scale marks 31 on the circumference of the top stopper 3. This makes it more convenient for the sampling personnel to accurately rotate the rotating plate 4, so that the magnetic attraction part at the bottom end of the pipette 2 can be accurately magnetically connected with the liquid guide holes 42 at the top of the four groups of liquid storage cylinders 5 on the rotating plate 4.

[0026] Among them, threaded openings 43 matching the liquid storage cylinders 5 are opened at equal intervals on the circumference of the bottom of the rotating plate 4.

In this way, sewage of different depths can be sampled and collected one by one at one time, without the need to frequently disassemble and replace the liquid storage cylinders 5, thereby improving the efficiency of sewage fixed-point sampling and making the operation more convenient.

[0027] Among them, the liquid guide hole 42 is an L-shaped structure, the bottom end of the liquid guide hole 42 extends to the inner cavity of the threaded opening 43, the top end of the liquid guide hole 42 is connected to the bottom end of the liquid suction tube 2 by magnetic adsorption, and multiple groups of liquid storage cylinders 5 can be installed in the corresponding threaded opening 43 at the bottom of the rotating plate 4 through threads, so as to perform stratified sampling of sewage at different depths.

[0028] Working principle: When sampling sewage in a fixed environment, the outer cylinder 1 can be stably supported at the sewage collection point of the environment through the bottom plate 12;

[0029] Then, the bottom end of the pipette 2 is extended into the sampled sewage, and the sewage can be sucked into the pipette 2 by installing a pump body near the top of the outer cylinder 1, and can be introduced into the liquid storage cylinder 5 for storage through the bottom end of the pipette 2;

[0030] When sampling different depths of environmental sewage at a fixed point, the rotating plate 4 can be rotated ninety degrees clockwise in sequence, so that the ends of the pipette 2 passing through the outer wall of the rotating plate 4 are respectively connected to the liquid guide holes 42 at the tops of the four groups of liquid storage cylinders 5 by magnetic attraction, so that the sewage at different depths at the fixed point can be extracted and collected in layers into the corresponding four groups of liquid storage cylinders 5, realizing the one-time sampling and collection of sewage at different depths one by one, without the need to frequently disassemble and replace the liquid storage cylinders 5, thereby improving the efficiency of sewage fixed-point sampling and making the operation more convenient.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
