Technical Field

[0001] This utility model relates to the field of sampling and filtration technology, and in particular to a sampling and filtration device for water environment testing. Background Technology

[0002] Water environment monitoring is a comprehensive analysis of the water environment, using physical, chemical, and biological techniques to qualitatively, quantitatively, and systematically analyze pollutants and their related components, in order to explore and study the changing patterns of water environment quality.

[0003] In the process of water environment monitoring, it is necessary to manually use containers to sample the water area to be tested. However, some water areas contain a large amount of debris, and direct sampling will cause the debris to enter the sampling container, resulting in sample contamination. Based on this, this utility model proposes a sampling and filtering device for water environment monitoring. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a sampling and filtration device for water environment monitoring, thereby solving the problems mentioned in the background section.

[0005] A sampling and filtration device for water environment testing includes a sampling vessel and a filter screen cover connected to the top of the sampling vessel via a threaded groove. A vertical rod is provided above the filter screen cover. The device also includes a transmission mechanism disposed on the filter screen cover and the vertical rod for cleaning debris from the outer wall of the filter screen cover. The transmission mechanism includes a cleaning unit and a guiding unit. The cleaning unit is used to clean the debris accumulated on the outer wall of the filter screen cover, and the guiding unit is used to provide power for the movement of the cleaning unit.

[0006] By adopting the above technical solution, the debris accumulated in the filter holes on the outer wall of the filter cover can be cleaned, thus preventing the filter holes from becoming clogged.

[0007] The cleaning unit includes a rotating sleeve and a cleaning rod. The rotating sleeve is rotatably connected to the top of the filter cover. The rotating sleeve is used to drive the cleaning rod, which is fixed on its outer wall, to rotate synchronously. The cleaning rod in the rotating state is used to clean the debris accumulated on the outer wall of the filter cover.

[0008] By adopting the above technical solution, the filter holes opened on the outer wall of the filter screen are cleaned.

[0009] The guiding unit includes a movable rod, a connecting plate, a guide block, a guide groove, and a guide rod. The movable rod is vertically slidably installed on the inner wall of the upright and extends through the upright to both ends of the upright. The upright is rotatably connected to the inner cavity of the rotating sleeve. A connecting plate is fixed to the outer wall of the bottom end of the movable rod. A guide block extending into the inner cavity of the guide groove is fixed to the outer wall of the connecting plate. The guide groove is spirally formed in the inner cavity of the rotating sleeve. A guide rod penetrating a rectangular groove in the inner wall of the filter cover is fixed to the bottom end of the connecting plate.

[0010] By adopting the above technical solution, power is provided for the rotation of the cleaning rod, so that the cleaning rod is subjected to the up-and-down reciprocating pressure from the movable rod and rotates left and right.

[0011] The inner cavity of the guide groove matches the outer wall of the guide block.

[0012] The above technical solution is used to provide guidance for the activities of the guide block.

[0013] The inner cavity of the upright is formed with a sliding groove for the vertical movement of the rectangular protrusion.

[0014] By adopting the above technical solution, guidance is provided for the vertical movement of the movable rod.

[0015] The outer wall of the cleaning rod is generally L-shaped. The two cleaning rods are symmetrically fixed on the outer wall of the rotating sleeve. The outer wall of the vertical rod of the cleaning rod is formed with a brush for cleaning the filter holes on the outer wall of the filter screen cover.

[0016] By adopting the above technical solution, the outer wall of the vertical rod of the "L"-shaped cleaning rod cleans the outer wall of the side of the filter cover.

[0017] The beneficial effects of this sampling and filtration device for water environment monitoring are: By setting up a transmission mechanism, when water resources are sampled through a sampling vessel, debris in the water will enter the sampling vessel with the water flow. As the water flows, it will come into contact with the outer wall of the filter screen cover, causing the filter screen holes to become clogged. At this time, by pressing the movable rod, the guide block will apply a squeezing force to the guide groove, which will be transmitted to the cleaning rod. The cleaning rod will rotate along the outside of the filter screen cover to clean the clogged filter screen holes, ensuring sampling efficiency. Attached Figure Description

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0021] Reference Figures 1 to 3 A sampling and filtration device for water environment testing includes a sampling vessel 1 and a filter screen cover 2 connected to the top of the sampling vessel 1 via a threaded groove. A vertical rod 3 is provided above the filter screen cover 2. The device also includes a transmission mechanism 4 provided on the filter screen cover 2 and the vertical rod 3 for cleaning debris from the outer wall of the filter screen cover 2. The transmission mechanism 4 includes a cleaning unit and a guiding unit. The cleaning unit is used to clean the debris accumulated on the outer wall of the filter screen cover 2, and the guiding unit is used to provide power for the movement of the cleaning unit. The cleaning unit includes a rotating sleeve 401 and a cleaning rod 402. The rotating sleeve 401 is rotatably connected to the top of the filter screen cover 2. The rotating sleeve 401 is used to drive the cleaning rod 402, which is fixed on its outer wall, to rotate synchronously. The cleaning rod 402 in the rotating state is used to clean the debris accumulated on the outer wall of the filter screen cover 2. The guide unit includes a movable rod 403, a connecting plate 404, a guide block 405, a guide groove 406, and a guide rod 407. The movable rod 403 is vertically slidably installed on the inner wall of the upright rod 3 and extends through the upright rod 3 to both ends of the upright rod 3. The upright rod 3 is rotatably connected to the inner cavity of the rotating sleeve 401. The connecting plate 404 is fixed to the outer wall of the bottom end of the movable rod 403. The guide block 405 extending into the inner cavity of the guide groove 406 is fixed to the outer wall of the connecting plate 404. The guide groove 406 is spirally opened in the inner cavity of the cleaning rod 402. The guide rod 407 penetrating the rectangular groove in the inner wall of the filter cover 2 is fixed to the bottom end of the connecting plate 404.

[0022] In this embodiment: when water resources need to be tested, the stand rod 3 is held by hand, and the filter screen cover 2 and sampling vessel 1 at the bottom of the stand rod 3 are placed in the water. The water flows through the filter holes of the filter screen cover 2 and enters the inner cavity of the sampling vessel 1 to complete the water resource sampling. When the filter holes are blocked by impurities in the water, the movable rod 403 is pushed and pulled, causing the connecting plate 404 and guide block 405 fixed at the bottom of the movable rod 403 to move with the up and down reciprocating movement of the movable rod 403. The moving guide block 405 will give the guide groove 406 a squeezing force. The force-bearing guide groove 406 will transmit the force to the rotating sleeve 401, causing the rotating sleeve 401 to rotate reciprocally under the external force. The rotating cleaning rod 402 cleans the filter holes on the outer wall of the filter screen cover 2 through the cleaning brushes distributed on the vertical rod, ensuring sampling efficiency and preventing blockage. It should be noted that the inner cavity of the rotating sleeve 401 is formed with an annular block that matches the annular groove on the outer wall of the stand rod 3.

[0023] Please refer to this carefully. Figures 1 to 3 The outer wall of the guide block 405 is generally spherical, the inner cavity of the guide groove 406 matches the outer wall of the guide block 405, the outer wall of the movable rod 403 is formed with a rectangular protrusion, the inner cavity of the upright rod 3 is formed with a sliding groove for the vertical movement of the rectangular protrusion, the outer wall of the cleaning rod 402 is generally L-shaped, the two cleaning rods 402 are symmetrically fixed on the outer wall of the rotating sleeve 401, and the outer wall of the vertical rod of the cleaning rod 402 is formed with a brush for cleaning the filter holes on the outer wall of the filter screen cover 2.

[0024] In this embodiment: This structure allows the movable rod 403 to move vertically along the inner cavity of the upright rod 3 under the outer wall protrusion of the movable rod 403, and under the action of the rectangular outer wall of the guide rod 407, the vertically moving guide rod 407 moves vertically along the inner wall rectangular groove of the filter cover 2. When the guide block 405 provides a thrust to the guide groove 406 and drives the rotating sleeve 401 and the cleaning rod 402 to rotate, the sampling vessel 1 and the filter cover 2 will not be affected by the rotation of the rotating sleeve 401.

[0025] Working principle: By holding the upright pole 3 by hand, the filter screen cover 2 and sampling vessel 1 at the bottom of the upright pole 3 are placed in water. Water flows through the filter holes of the filter screen cover 2 and enters the inner cavity of the sampling vessel 1 to complete the water sampling. When the filter holes are blocked by impurities in the water, the movable rod 403 is pushed and pulled, causing the connecting plate 404 and guide block 405 fixed at the bottom of the movable rod 403 to move up and down with the movable rod 403. The moving guide block 405 will exert a squeezing force on the guide groove 406. The force-bearing guide groove 406 will transmit the force to the rotating sleeve 401, causing the rotating sleeve 401 to rotate back and forth under the external force. The rotating cleaning rod 402 cleans the filter holes on the outer wall of the filter screen cover 2 through the cleaning brushes distributed on the vertical rod, ensuring sampling efficiency and preventing blockage.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
