Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a multi-depth sampling device. Background Art

[0002] The water in the reservoir has a periodic and seasonal high manganese content. The water plant uses water from the reservoir for water supply. If the manganese content in the water in the reservoir is high, it will not only affect the safety of the water quality, but also affect the production process of the water plant. Therefore, it is necessary to regularly test and analyze the manganese content in the water at different depths in the reservoir. In addition, when the manganese content in the water in the reservoir is high, the water plant also needs to test the manganese content index of the stratified water samples in the horizontal flow sedimentation tank to determine the manganese precipitation of the sedimentation tank bottom mud. In summary, accurate collection of water samples at different depths is important for result analysis and process adjustment.

[0003] At present, water plants generally rely on manual control of the depth of the sampler to collect water samples at a certain depth. However, this method is not only labor-intensive, but also when the sampler sinks, some water samples from the upper layer will enter the sampler, causing mixing, which will affect the test results.

[0004] The above-mentioned defects are expected to be overcome by those skilled in the art. Utility Model Content

[0005] In order to solve the above problems in the prior art, the utility model provides a multi-depth sampling device which is simple to operate and flexible to use.

[0013] By providing an outer sleeve, a sampling tube, multiple water taps, a positioning rod and a rotating handle, the rotating handle is rotated to rotate the outer sleeve so that the rotating handle overlaps with the positive projection of the positioning rod in the direction of the outer sleeve. At this time, the outer water sampling hole of the outer sleeve is aligned with the inner water sampling hole of the sampling tube, and water flows into each sampling chamber of the sampling tube from the outer water sampling hole and the inner water sampling hole, thereby realizing accurate collection of water samples at different depths. The multi-depth sampling device has a simple structure and is easy to operate, can reduce manual labor intensity, and prevent water samples at different depths from mixing with each other. It is suitable for collecting water samples from different water sources and various production process sections of a water plant.

[0014] Furthermore, the spacings between adjacent partitions are equal, and the volumes of the sampling chambers are equal, so that the multi-depth sampling device can quantitatively collect water samples at different depths.

[0015] Preferably, the inner water sampling hole is arranged on the tube wall of the sampling chamber at one end close to the opening end of the sampling tube; and the water outlet tap is arranged at one end of the sampling chamber away from the inner water sampling hole.

[0016] Preferably, the inner water sampling holes are staggered along the height direction of the sampling tube, so that the water sample in the upper layer will not flow into the sampling chamber in the lower layer through the inner water sampling holes in the lower layer when flowing down, thus avoiding mixing of layers and improving the accuracy and reliability of the detection results.

[0017] Preferably, the water outlet taps are distributed in a straight line along the height direction of the sampling tube.

[0018] Furthermore, a plurality of drainage holes are provided at the bottom of the outer sleeve. Preferably, the drainage holes are distributed in a grid shape. By providing the drainage holes, the accumulated water between the outer sleeve and the sampling tube can be discharged, thereby preventing the multi-depth sampling device from internally accumulating water.

[0019] Furthermore, the height of the sampling tube is higher than the height of the outer sleeve; and the outer diameter of the sampling tube is smaller than the outer diameter of the outer sleeve.

[0020] Furthermore, the outer sleeve can rotate around the sampling tube in a range of 0° to 180°.

[0021] Furthermore, the outer sleeve, sampling tube, partition and water outlet faucet are all stainless steel components. Stainless steel components have good corrosion resistance, can extend the service life of the multi-depth sampling device, and are highly practical.

[0032] The height of the sampling tube 2 is higher than that of the outer sleeve 1, so that the staff can rotate the rotating handle 6 to drive the outer sleeve 1 to rotate around the sampling tube 2; in this embodiment, the outer sleeve 1 rotates around the sampling tube 2 in a range of 0° to 180°. The outer diameter of the sampling tube 2 is smaller than the outer diameter of the outer sleeve 1. In this embodiment, the outer diameter of the sampling tube 2 is 53mm and the thickness is 3mm; the outer diameter of the outer sleeve 1 is 56mm and the thickness is 3mm. The bottom of the outer sleeve 1 is also provided with a plurality of drainage holes 13 for draining the accumulated water between the outer sleeve 1 and the sampling tube 2, avoiding the generation of internal water accumulation in the multi-depth sampling device, and facilitating cleaning and maintenance. Specifically, the number of drainage holes 13 is greater than 4.

[0037] When using the multi-depth sampling device to collect water samples, first, rotate the rotating handle 6 so that the rotating handle 6 and the positioning rod 5 are staggered in the direction of the outer sleeve 1. At this time, the outer water sampling hole 11 and the inner water sampling hole 22 are staggered; then, after inserting the multi-depth sampling device into the specified position in the water, rotate the rotating handle 6 so that the rotating handle 6 and the positioning rod 5 are overlapped in the direction of the outer sleeve 1. At this time, the outer water sampling hole 11 and the inner water sampling hole 22 are aligned, and the external water enters each sampling chamber 21 from the outer water sampling hole 11 and the inner water sampling hole 22; after the sampling is completed, rotate the rotating handle 6 again so that the rotating handle 6 and the positioning rod 5 are staggered in the direction of the outer sleeve 1. At this time, the outer water sampling hole 11 and the inner water sampling hole 22 are staggered again, lift the multi-depth sampling device, and open the water outlet taps 4 in sequence to obtain water samples of different depths.
