Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a portable water quality detection sampling device. Background Art

[0002] Portable water quality testing and sampling devices play a vital role in on-site water quality monitoring. They can improve sampling efficiency, ensure water sample quality, and provide a reliable sample basis for subsequent water quality analysis.

[0003] Although current technology has many advantages, its disadvantage is that the sampling cups are of different sizes, so they cannot be precisely connected to the sampling device. When the staff is taking samples, the sampling cups may fall into the water, affecting the sampling efficiency and reducing the user experience. At the same time, a single sampling device may only be able to obtain water samples close to the staff, and there is a large difference in quality between this part of the sample and the water in the middle to be sampled, resulting in inaccurate test results.

At the same time, using a single sampling device may only be able to obtain water samples close to the staff, and there is a large difference in quality between the sample in this part and the water in the middle to be sampled, resulting in inaccurate detection results.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a portable water quality detection sampling device, comprising: a rotating block, and also comprising: an operating handle 1, the outer surface of the rotating block is provided with a plurality of slide grooves 1, the inner surfaces of the plurality of slide grooves 1 are movably embedded with sliding rods, the tops of the plurality of sliding rods are fixedly connected with clamping blocks, the bottoms of the plurality of sliding rods are fixedly connected with limiting plates, the top of the rotating block is provided with a fixed block, the fixed block is provided with a slide groove 2 on a side close to the plurality of sliding rods, the outer surface of the rotating block is fixedly connected with an operating rod, the outer surface of the operating rod is provided with a slide groove 3, the inner surface of the slide groove 3 is movably embedded with a sliding block, the top of the sliding block is fixedly connected with a limiting rod 1, and the outer surface of the sliding block is fixedly connected with a spring, which can clamp sampling cups of different sizes, thereby avoiding the incompatibility between the sampling cup and the sampling device and improving the sampling efficiency.

[0006] As a preferred embodiment, an operating handle 2 is movably sleeved on the outer surface of the operating handle 1, and two limiting grooves are provided on the outer surface of the operating handle 2. When the operating handle 1 is pulled out, the sampling cup can obtain water samples far away from the staff, thus avoiding the singleness and particularity of sampling.

[0007] As a preferred embodiment, a plurality of limit blocks are fixedly connected to one side of the fixed block close to the operating rod, and the spring is fixedly connected to the inner wall of the slide groove three. The slide groove three can limit the movement trajectory of the slider to avoid derailment of the slider.

[0008] As a preferred embodiment, the plurality of slide bars are movably embedded in the inner surfaces of the plurality of slide grooves 2, the operating handle 1 is fixedly connected to the outer surface of the fixed block, and the slide groove 2 can limit the slide bar to prevent the slide bar from derailing.

[0009] As a preferred embodiment, two positioning rods are movably embedded in the outer surface of the operating handle 1, and the positioning rods can position the spring piece.

[0010] As a preferred embodiment, two fixing columns are fixedly connected to the outer surface of the operating handle 1, and working blocks are movably sleeved on the outer surfaces of the two fixing columns, and the fixing columns can position the working blocks.

[0011] As a preferred embodiment, the inner surfaces of the two positioning rods are fixedly embedded with spring plates, which can be stuck in the end grooves on the working block to prevent the working block from continuing to rotate.

[0012] As a preferred embodiment, the inner surfaces of the two working blocks are fixedly embedded with limit rods 2, and the two limit rods 2 are movably embedded in the inner surfaces of the two limit grooves. The limit grooves can limit the limit rods 2 to avoid derailment of the limit rods 2.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] The spring is then pulled back to move the slider to the middle position of the plurality of limit blocks, and the slider is driven to move on the inner surface of the slide groove 3 and squeeze the spring, so that the spring obtains elastic potential energy. The operating lever is then manually rotated to drive the rotating block to rotate, so that the rotating block drives the plurality of slide rods to move through the plurality of slide grooves 1, and the plurality of slide rods are limited by the plurality of slide grooves 2 on the fixed block, and finally the plurality of slide rods drive the plurality of clamping blocks to move toward the sampling cup. After the plurality of clamping blocks clamp the sampling cup, the limiting rod is then released, and the spring releases the elastic force at this time, so that the slider drives the limiting rod to move to the middle position of the plurality of limit blocks, forming a self-locking state, and then sampling cups of different sizes can be clamped, thereby avoiding the incompatibility between the sampling cup and the sampling device, improving the sampling efficiency, and improving the user experience.

[0015] 2. According to the utility model, when it is necessary to sample the central position of the water source to be sampled, the two limit rods 2 are manually pulled to move the limit rods 2 into the upper cavities of the two limit grooves. At this time, the two limit rods 2 drive the two working blocks to make circular motions with the two fixed columns as the center, and the spring pieces on the two positioning rods move to one of the grooves on the two working blocks. Then, the operating handle 2 is pulled to make a part of the operating handle 1 leave the operating handle 2. When the operating handle 1 and the operating handle 2 are long enough, the two limit rods 2 are moved to the bottom teeth of the two limit grooves. At this time, the two spring pieces are stuck in the other grooves on the two working blocks and form a self-locking with the two working blocks. Because the operating handle 1 is pulled out, the sampling cup can take water samples far away from the staff, thereby avoiding the singleness and particularity of sampling and improving the accuracy of the test results.
