Description

Technical Field

[0001] The utility model belongs to the field of water quality sampling, and in particular relates to a portable water quality collector. Background Art

[0002] In the field of water environment, water quality samples are generally collected using a water quality sample collector (also called a water quality sampler), which is used to collect water quality samples from water bodies for laboratory analysis and testing. In order to ensure the scientificity and representativeness of water quality sample collection, samples must be collected in accordance with relevant national standards.

[0003] The water quality collectors currently on the market are usually large in size, which is not only inconvenient to carry, but also takes up a large storage space when not in use, resulting in a waste of space. At the same time, due to the fixed internal volume, only the same amount of water can be taken out each time. If the sampled water volume is more than the required water volume, this will increase the weight of the water quality collector, which will also cause the problem of inconvenience in carrying. If the sampled water volume is less than the required water volume, multiple sampling processes will be required, which to a certain extent affects the water quality sampling efficiency. Utility Model Content

[0004] In view of one or more of the above defects or improvement requirements of the prior art, the utility model provides a portable water quality collector, which has the advantages of portability and high applicability.

[0005] To achieve the above-mentioned purpose, the utility model provides a portable water quality collector, comprising two fixing rings, a corrugated folding barrel and a connecting assembly, wherein the side wall of the corrugated folding barrel is corrugated, the two fixing rings are located at the upper and lower sides of the corrugated folding barrel, the upper and lower ends of the corrugated folding barrel respectively penetrate the two fixing rings and are fixedly connected to the fixing rings, the left side of the connecting assembly is connected to the right side wall of the two fixing rings, the front side of the top of the corrugated folding barrel is provided with a sampling assembly, and the rear side of the top of the corrugated folding barrel is connected with an air outlet valve;

[0006] The sampling assembly includes an inlet valve and a water pump. The bottom of the inlet valve is connected to the front side of the top of the corrugated folding barrel. A sealing ring is fixedly connected to the top of the inlet valve. The water outlet of the water pump passes through the sealing ring and the inlet valve and is threadedly connected to the inlet valve. The water inlet end of the water pump is connected to an extension pipe.

[0007] The connecting assembly includes a fixed platform, a mounting platform, a ring block and a fixed screw. The ring block is a square frame. The left side of the fixed platform is fixedly connected to the right side of the lower fixed ring, the left side of the mounting platform is fixedly connected to the right side of the upper fixed ring, and the front and rear edges of the right side of the top of the fixed platform are respectively fixedly connected with support columns. The bottom end of the ring block is rotatably connected to the upper ends of the opposite sides of the two support columns. The fixed screw is located on the right side of the mounting platform, and the left end of the fixed screw passes through the ring block and the mounting platform and is threadedly connected to the mounting platform. The fixed screw is slidably connected to the inner wall of the ring block.

[0008] A pointer is fixedly connected to the front side of the mounting platform, and the front support column and the front wall of the ring block are respectively provided with scales.

[0009] In general, compared with the prior art, the above technical solutions conceived by the utility model have the following beneficial effects:

[0010] (1) The corrugated folding barrel can be expanded or folded by changing the distance between the two fixed rings, thereby adjusting the internal volume of the corrugated folding barrel, so that the sampler can be adjusted according to different sampling volume requirements. During the adjustment process, the relative position of the pointer and the scale can be observed to know the current internal volume of the corrugated folding barrel, so as to make quantitative adjustments.

[0011] (2) After use, the distance between the two fixing rings can be shrunk and the corrugated folding barrel can be folded. Then, after the ring block is folded, the fixing screw can be rotated until it contacts the support column. The friction between the two fixing rings can fix the distance between the two fixing rings, thereby reducing the space occupied by the collector during storage and achieving the effect of being easy to carry.
