Description

Technical Field

[0001] This utility model relates to the field of water environment sampling technology, specifically to an auxiliary sampling device for water environment management. Background Technology

[0002] The water environment refers to the spatial environment in which water forms, distributes, and transforms in nature. It encompasses the totality of various natural and related social factors surrounding water bodies that directly or indirectly affect human life and development, and their normal functions. Some also refer to the environment of relatively stable natural bodies of water bounded by land. Water sampling is an essential part of water environment protection; the sampled water needs to be tested to implement appropriate treatment and protection measures.

[0003] Existing sampling devices are generally complex in structure, large in size, heavy in weight, and inconvenient to carry. Moreover, these devices contain a large number of electrical components, which are prone to failure when sampling underwater. They are also relatively expensive, and other objects inevitably float on the surface of the water body being tested, which can affect the sampling process. Utility Model Content

[0013] (III) Beneficial Effects

[0014] This utility model provides an auxiliary sampling device for water environment treatment. It has the following beneficial effects:

[0015] 1. When using this auxiliary sampling device for water environment management, the entire device is vertically lowered into the water area to be sampled by holding the pull rope. The fixed plate floats on the water surface under the action of the float tube. When the pull rope is released, the counterweight moves the connecting frame down, and the connecting frame moves the filter tube into the water. The flow-blocking rod contacts the bottom wall of the filter tube under the action of gravity. At this time, the water sample enters the sampling tube from the inlet pipe. This solves the problem that other objects inevitably float on the surface of the water body when using existing sampling devices, which affects the sampling. It has the advantage of filtering impurities.

[0016] 2. When using this water environment treatment auxiliary sampling device, pulling the rope causes the flow-blocking rod to move upward. The bottom of the flow-blocking rod obstructs the flow at the bottom of the inlet pipe. At the same time, the flow-blocking rod moves the sampling cylinder upward through the inlet pipe. Under the action of the locking block and the locking frame, the sampling cylinder moves the support frame. The support frame moves the filter cylinder upward. The filter cylinder moves the fixing plate away from the water surface through the limiting ring, which has the advantage of facilitating sampling. Attached Figure Description

The threaded ring facilitates the limiting of the top of the filter cylinder 4 by the connecting cover 11. A rotating block 12 is rotatably connected to the center of the connecting cover 11. Both the connecting cover 11 and the rotating block 12 have moving grooves inside. Rubber pads 13 are fixedly connected to both ends of the bottom wall of the connecting cover 11 at the top of the sampling cylinder 10. The inner wall of the rubber pads 13 contacts the side wall of the sampling cylinder 10. A positioning frame 14 is fixedly connected to the top of the support frame 9.

[0025] A water inlet pipe 16 is connected to the bottom of the sampling cylinder 10. A flow-blocking rod 17 is slidably connected inside the water inlet pipe 16. The entire device is vertically lowered into the water area to be sampled by holding the pull rope 18. The fixing plate 1 floats on the water surface under the action of the float 2. The pull rope 18 is released, and the counterweight 8 moves the connecting frame 7 downward. The connecting frame 7 moves the filter cylinder 4 into the water. The flow-blocking rod 17 contacts the bottom wall of the filter cylinder 4 under the action of gravity. At this time, the water sample enters the sampling cylinder 10 from the water inlet pipe 16.

[0026] Working principle:

[0027] When using this auxiliary sampling device for water environment management, the entire device is vertically lowered into the water area to be sampled by holding the pull rope 18. The fixed plate 1 floats on the water surface under the action of the float 2. The pull rope 18 is released, and the counterweight 8 drives the connecting frame 7 to move down. The connecting frame 7 drives the filter cylinder 4 into the water. The flow-blocking rod 17 contacts the bottom wall of the filter cylinder 4 under the action of gravity. At this time, the water sample enters the sampling cylinder 10 from the inlet pipe 16. After sampling is completed, the pull rope 18 is pulled up, and the pull rope 18 drives the flow-blocking rod 17 to move up. The bottom of the flow-blocking rod 17 blocks the flow at the bottom of the inlet pipe 16. At the same time, the flow-blocking rod 17 drives the sampling cylinder 10 to move up through the inlet pipe 16. The sampling cylinder 10 drives the support frame 9 to move under the action of the locking block 15 and the locking frame 14. The support frame 9 drives the filter cylinder 4 to move up. The filter cylinder 4 drives the fixed plate 1 away from the water surface through the limiting ring 6.
