[0026] Example

[0027] Reference Figure 1 - Figure 2 , which is a water quality online detection instrument sampling stabilizing tank disclosed in the utility model, comprising a stabilizing tank body 1 and a horizontally arranged water inlet pipe 2, a water outlet pipe 3, an overflow pipe 4 and a sampling pipe 5;

[0028] Among them, the water inlet pipe 2 is fixedly connected to the side wall of the swirl pot body 1 and is located near the top end of the swirl pot body 1; the water outlet pipe 3 is fixedly connected to the side wall of the swirl pot body 1 and is located near the bottom end of the swirl pot body 1, and the water outlet pipe 3 is arranged at a side position of the swirl pot body 1 away from the water inlet pipe 2; the overflow pipe 4 is fixedly connected to the side wall of the swirl pot body 1 and is located near the top end of the swirl pot body 1, and the overflow pipe 4 is arranged at a side position near the water outlet pipe 3, and the sampling tube 5 is fixedly connected to the side wall of the swirl pot body 1 and is located between the water outlet pipe 3 and the overflow pipe 4;

[0029] In this embodiment, the simmer tank body 1 is made of a transparent material, such as plastic, glass, etc., to facilitate observation of the water sample;

[0030] Further, the length of the main body 1 of the steady flow tank is 420 mm and the height is 400 mm; the water inlet pipe 2 is used to introduce the water sample into the main body 1 of the steady flow tank, and the water outlet pipe 3 is used to discharge the water sample from the main body 1 of the steady flow tank to ensure the cyclic update of the water sample. The overflow pipe 4 is used for overflow to ensure that the water level in the main body 1 of the steady flow tank does not exceed the limit, thereby preventing the water sample from flowing out of the main body 1 of the steady flow tank; a water quality detector is fixedly connected to the sampling pipe 5 and is used to provide the water sample to the water quality detector for water sample detection.

[0031] Further, a drain pipe 6 vertically arranged downward is fixedly communicated with the bottom surface of the main body 1 of the steady flow tank, and the drain pipe 6 is used to drain the water sample in the main body 1 of the steady flow tank.

[0032] Valves 7 are arranged on the pipe bodies of the water inlet pipe 2, the overflow pipe 4, the water outlet pipe 3, the sampling pipe 5 and the drain pipe 6. The valve on the pipe body of the sampling pipe 5 is a check valve, and the check valve is arranged to prevent the water sample from flowing back.

[0033] Further, a plurality of linearly distributed and vertically arranged baffle plates 9 are fixed in the main body 1 of the steady flow tank. The distribution direction of the plurality of baffle plates 9 is parallel to the arrangement direction of the water inlet pipe 2, and the plurality of baffle plates 9 are arranged staggered up and down. A water passing port 10 is formed between the upper baffle plate 9 and the bottom surface of the main body 1 of the steady flow tank, and the lower baffle plate 9 abuts against the bottom surface of the main body 1 of the steady flow tank;

[0034] In this embodiment, the length of the baffle plate 9 is 300 mm, and the distance between the plurality of baffle plates 9 is 120 mm.

[0035] In this embodiment, the baffle plate 9 can be set to a wavy shape.

[0036] The working principle and beneficial effects of the present utility model are as follows:

[0037] After the water sample enters the main body 1 of the steady flow tank from the water inlet pipe 2, the baffle plate 9 changes the water flow direction and speed of the water sample, so that the bubbles in the water sample accelerate to float upward. After multiple collisions and rotations, the bubbles are fully removed. The unremoved bubbles overflow from the overflow pipe along with the water flow. The water sample is buffered in the main body 1 of the steady flow tank to eliminate fluctuations and disturbances, remove bubbles, and flow by gravity from the sampling pipe 5 to the water quality detector, providing a stable supply of the water sample.

[0038] At the same time, the water outlet pipe 3 is in an open state to discharge the water sample, accelerating the update of the water sample in the main body 1 of the steady flow tank, shortening the residence time of the water sample in the main body 1 of the steady flow tank, ensuring that the sampled water is the latest water sample, and since the position of the water outlet pipe 3 is lower than that of the sampling pipe 5, therefore, the impurities in the water sample can flow out from the water outlet pipe 3, further reducing the interference of the external environment on the water sample, ensuring the stability of the water sample sampling by the water quality detector, and improving the detection accuracy of the water quality detector.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
