[0002] Environmental detection refers to the activity of monitoring, analyzing and evaluating various substances and factors in the environment to understand the environmental quality status and its changing trends, generally including atmospheric environment detection, water environment detection, soil detection, etc.

[0003] In water environment detection, a sampler is usually used for sampling and analysis. The water quality sampler for environmental detection is an advanced device specifically used for collecting water samples for environmental detection and analysis. The water quality sampler generally consists of a sampling pump, a sampling pipeline, a control unit, a sample container, etc.

[0004] When sampling water quality, sampling personnel usually use some simple manual samplers, such as hand-operated pump samplers, bucket samplers, etc. These samplers usually consist of a container and a collection device, and the water sample can be sucked into the container through manual operation. However, the sampling depth cannot be accurately set according to the actual situation, it is difficult to accurately judge the position of the pollution source in the water body, which increases the difficulty of pollution source location, thus delaying the process of pollution control. Moreover, during the use of the sampler, various dirt, impurities and microorganisms will accumulate inside, and it is very difficult to thoroughly clean some narrow corners, gaps and complex structural parts, which greatly affects the sampling results. Therefore, a new water quality sampler for environmental monitoring is proposed to solve the above problems. Content of the Utility Model

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Refer to Figure 1 and Figure 2 An embodiment provided by the present invention: A new type of water quality sampler for environmental monitoring includes a sampling bucket 2. The top end of the protrusion two 16 is fixedly connected with a depth-setting structure for setting the diving depth of sampling. The depth-setting system includes a depth-setting rope 5 that can accurately adjust the depth of the sampling water layer. The top end of the protrusion two 16 is fixedly connected to the bottom end of the depth-setting rope 5. The outer surface of the depth-setting rope 5 is sleeved with a floating ball 4. The front end of the floating ball 4 is threadedly connected with a knob 3 to facilitate fixing the position of the floating ball 4. The floating ball 4 is a polyethylene foam ball, and the depth-setting rope 5 is a graduated rope to provide sufficient buoyancy during sampling and improve sampling accuracy.

[0038] Refer to Figures 3 - 5 One side of the top end of the sampling bucket 2 is rotatably connected with a stop bar 13. The left side of the bottom end of the stop bar 13 is fixedly connected with a magnet 12. The left top end of the stop bar 13 is fixedly connected with a protrusion two 16. The center position of the top end of the sampling bucket 2 is slidably connected with a water-pumping shaft rod 9. A engaging hole 17 is provided on the surface of the water-pumping shaft rod 9 near the top end and corresponds to the T-shaped stop block 14 to facilitate the engagement of the T-shaped stop block 14 with the engaging hole 17 to fix the position of the water-pumping shaft rod 9.

[0039] Refer to Figure 6 and Figure 7 The center position of the right end of the stop bar 13 is fixedly connected with a T-shaped stop block 14. A plurality of tensile springs 8 are fixedly connected to the inner top end of the sampling bucket 2 at equal intervals. The bottom ends of the plurality of tensile springs 8 are all fixedly connected to the bottom end of the water-pumping shaft rod 9. Two protrusions three 19 are fixedly connected to the top end of the sampling bucket 2. The top end of the protrusion three 19 is engaged with a handle 7. The outer surface of the bottom end of the sampling bucket 2 is threadedly connected with a filter cover 1 to prevent the sampling bucket 2 from being blocked. A plug 6 is screwed on the outer surface of the sampling bucket 2 near the bottom end to facilitate taking water after sampling.

[0040] Refer toFigure 8 and Figure 9 At the bottom position of the sampling bucket 2, a check valve device is threadedly connected. The check valve device is used for taking water and storing it. The check valve device includes a valve seat 10. The bottom end of the sampling bucket 2 is threadedly connected to the outer surface of the valve seat 10. Two first protrusions 15 are fixedly connected to the bottom end of the valve seat 10. One side of the top end of the valve seat 10 is rotatably connected with a valve plate 11 for unidirectionally conducting the sampled water quality into the sampling bucket 2.

[0041] A sealing ring 18 is fixedly connected to the center near the bottom end of the pumping shaft rod 9. The sealing ring 18 is a rubber sealing ring to ensure the sealing performance inside the sampling bucket 2 after sampling is completed.

[0042] Working principle: Before water quality sampling, by rotating the knob 3, the position of the floating ball 4 on the depth-determining rope 5 is adjusted, that is, the depth of the water layer to be sampled is adjusted. The handle 7 is fixed through an external rope. Subsequently, the sampling bucket 2 is thrown into the water surface where sampling is required. After the sampling bucket 2 dives to a certain depth, since the position of the floating ball 4 on the depth-determining rope 5 is fixed, when the floating ball 4 provides buoyancy for the sampling bucket 2, due to the self-weight of the sampling bucket 2, the depth-determining rope 5 is pulled downward, but the pulling force is greater than the suction force of the magnet 12, resulting in the rotation of the blocking rod 13, canceling the engagement between the T-shaped block 14 and the engaging hole 17. The pumping shaft rod 9 moves upward under the action of the tension spring 8, and the sampled water automatically opens the valve plate 11 through the filter cover 1 and will automatically close after sampling is completed. When obtaining the water quality, the plug 6 can be opened. After using it for a period of time, the filter cover 1, valve seat 10, and valve plate 11 can be disassembled, and the inside of the sampling bucket 2 can be carefully cleaned.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
