[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0020] See also Figure 1-3 A water quality parallel sampling device is shown, comprising a water quality sampling pipeline, a tee for diverting the water quality sampling pipeline, a sampling bucket 10 connected to the water quality sampling pipeline, and a sampling rack for supporting and setting up the water quality sampling pipeline and the sampling bucket 10. Specifically, the sampling rack comprises a sampling platform consisting of an upper plate 20 and a lower plate 30. The upper plate 20 and the lower plate 30 are connected and fixed by four vertical rack rods 40 and are in a parallel state to each other. A support rod 50 is connected to the same side of the upper plate 20 and the lower plate 30; a support ring 60 for supporting the sampling bucket 10 is connected to the top of the support rod 50. In the embodiment of the utility model, the support ring 50 is welded to the support rod 50, wherein the upper plate 10 is provided with a plurality of through holes 111 for passing a water quality sampling pipeline, the water quality sampling pipeline comprising a first pipeline 80a connecting the sampling bucket outlet 61 and the inlet of the first-stage tee 70a, two sections of second pipelines 80b connected in parallel between the outlet of the first-stage tee 70a and the inlets of two second-stage tees 70b, and four sections of third pipelines 80c connecting each outlet of the two second-stage tees 70b. The water quality sample is diverted from the sampling bucket 10 through the water quality sampling pipeline and finally flows through the third pipeline 80c to the sampling bottle (not shown in the figure) placed on the lower plate.

[0021] In the embodiment of the utility model, the sampling rack also includes a three-way pipeline fixing bracket 90, which is arranged on the upper flat plate 20. The three-way pipeline fixing bracket has a square frame 91 at the bottom and a triangular frame 92 at the top. The interior of the triangular frame 92 is also connected to a vertical rib 93. The two ends of the three-way pipeline fixing bracket 90 and the top of the connecting rib 93 are respectively bonded or welded with a three-way clamping member 100. The three-way clamping member 100 includes a base 101 and a broken ring clamp 102 and a toothed portion 103 respectively arranged on the base 101. The broken ring clamp has two free ends, wherein One free end is a tooth end 102a with a tooth 104 on the outer surface, and can be elastically squeezed and wrapped by external force on the other free end 102b. The tooth portion 103 is arranged on one side of the tooth end 102a, including a tooth plate 103a and a tooth connecting plate 103b connected to the bottom plate 101; it can be made of plastic material. Since the tooth plate 103a and the tooth connecting plate 103b are thin plates, when the tooth plate 103a is pressed, it can be elastically opened within a certain angle range. When the tooth end 102a wraps the other free end 102b, the tooth plate 103a can be pressed to engage with the tooth 104 to lock the tee. The setting of the tee clamping member 100 enables the tee to be stably mounted on the sampling rack, and the water quality sampling pipeline can also be fastened and fixed on the tee pipeline fixing bracket 90 by a cable tie (not shown in the figure), which is very suitable for high sampling requirements and disposable water quality sampling pipelines.

[0022] Please combine Figure 4 As shown, the embodiment of the utility model has made some device improvements for the situation where 8 water quality samples need to be collected at the same time for parallel determination. It adds a middle plate 110, and correspondingly adds four third-level tees (not shown in the figure), corresponding three-way pipeline fixing brackets (not shown in the figure), and water quality sampling pipelines (not shown in the figure) connected to the four third-level tees. The middle plate 110 is provided with eight middle plate through holes 111 for passing the water quality sampling pipeline. The middle plate 110 is located between the upper plate 20 and the lower plate 30, and is detachably connected through the card slot 41 set on the vertical pipe.

[0023] In addition to manually injecting the sample into the sampling bucket 10, the embodiment of the utility model is also provided with a water inlet pipe 11 and a control valve (not shown in the figure). The water inlet pipe 11 can be connected to a water pipe and a water pump (not shown in the figure) for transportation. In addition, a control valve (not shown in the figure) is also provided on the pipeline 12 connecting the sampling bucket 10 and the first-stage three-way 80a.

[0024] To further ensure the stability of the entire device, the sampling rack is fixed by welding a square tube made of stainless steel, and the support rod 50 is an H-shaped support rod. In addition, the bottom of the sampling rack also has a stable frame 120 with an H-shaped structure.

[0025] Considering the portability of the device, the embodiment of the utility model also proposes a detachable structure. That is, the H-shaped support rod and the upper plate 20 and the lower plate 30 are connected by plug-in connection instead of welding. That is, the upper plate 20 and the lower plate 30 are provided with a socket connection 22, the support rod 50 is provided with an L-shaped socket plate, and the middle plate 110 can also be selectively provided with a socket connection 22.
