Technical Field

[0001] This utility model relates to the field of water body detection devices, specifically an enrichment detection device for rapid detection of PFOS and PFOA in water bodies. Background Technology

[0002] Solid-phase extraction (SPE) devices can be used to separate PFOS and PFOA from samples, enabling accurate detection of their content in subsequent analyses. A SPE device mainly consists of: a panel: a rigid flat plate with multiple holes for inserting extraction tubes or placing SPE columns; it supports and secures all components; support legs: cylindrical supports located at the four corners of the panel; their key function is to lift the panel and prevent compression of the guide needles mounted below; a cylinder: for controlling the vacuum level; typically equipped with a valve for controlling or releasing the vacuum; a vacuum source connection: connected to an external vacuum pump via a hose, forming a sealed space with the panel; and the vacuum pump: the power source of the device. It generates negative pressure within the sealed chamber by pumping air, driving the sample or solvent through the SPE columns at a stable and controllable flow rate.

[0003] During use, the panel may be placed upside down on the table, causing the SPE column placed on the panel to directly contact the table. When the panel is bumped or moved, the connection between the SPE column and the panel will wobble. After repeated wobble, the connection will deform and loosen, affecting subsequent use. Therefore, to address the above problems, an enrichment detection device for rapid detection of PFOS and PFOA in water is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses an enrichment detection device for rapid detection of PFOS and PFOA in water, including a cylinder 1, a panel 2 is engaged with the upper part of the cylinder 1, a fixing ring 3 is fixedly connected to the upper part of the panel 2 with an opening, a positioning bracket 4 is engaged with the fixing ring 3, and an adjusting bracket 5 is slidably connected to the inner wall of the positioning bracket 4.

[0025] The fixing ring frame 3 includes: a transverse cylinder 31 and an adjusting rod 32. The part of the fixing ring frame 3 with the opening on the side is fixedly connected to the end of the transverse cylinder 31, and the inner wall of the transverse cylinder 31 is slidably connected to the column of the adjusting rod 32.

[0026] The adjusting rod 32 includes a spring 321 and a spherical block 322. The end of the adjusting rod 32 is fixedly connected to the end of the spherical block 322, and the spring 321 is sleeved on the outer wall of the adjusting rod 32.

[0027] The fixing ring frame 3 also includes a fitting groove 30, and the upper part of the fixing ring frame 3 has a fitting groove 30;

[0028] The positioning bracket 4 includes: a guide groove 41, an adjusting ring 42, a locking block 421, and a locking hole 40. The guide groove 41 is provided on the side of the positioning bracket 4. The frame of the adjusting ring 42 is fixedly connected to the end of the positioning bracket 4. The end of the locking block 421 is fixedly connected to the bottom of the adjusting ring 42. The locking hole 40 is provided on the frame of the positioning bracket 4.

[0029] The guide groove 41 includes an upper adjustment groove 411 and a lower adjustment groove 412. The upper adjustment groove 411 is provided at the upper part of the guide groove 41, and the lower adjustment groove 412 is provided at the lower part of the guide groove 41.

[0030] The adjusting bracket 5 includes a protruding column 51, and the column body of the adjusting bracket 5 is fixedly connected to the end of the protruding column 51.

[0031] Working principle: Before engaging the cylinder 1 with the panel 2, first align the end of the positioning bracket 4 with the opening of the fixing ring 3 and insert it. Then, the positioning bracket 4 moves down through the inner wall of the fixing ring 3. During the movement, the outer wall of the positioning bracket 4 will squeeze the spherical block 322, causing the spherical block 322 to compress the spring 321. The spherical block 322 retracts into the transverse cylinder 31. As the adjusting ring 42 approaches the end face of the fixing ring 3, the adjusting ring 42 needs to be rotated by hand. This allows you to observe whether the locking block 421 has rotated to the position of the fitting groove 30. When the two are aligned, you can press the adjusting ring 42 to fit tightly against the end face of the fixing ring 3. The locking block 421 will then engage in the fitting groove 30. At the same time, the spring 321 will drive the spherical block 322 to insert into the locking hole 40. This completes the fixing of the positioning bracket 4, solving the problem that the traditional support leg is screwed into the threaded groove of the panel 2, which cannot be tightened when the nut is damaged and stripped.

[0032] After the positioning bracket 4 and the fixing ring 3 are fixed, rotate the end of the adjusting bracket 5 so that the protruding post 51 rotates from the lower adjusting groove 412 to the bottom of the guide groove 41. Then pull the adjusting bracket 5 upward, and the adjusting bracket 5 drives the protruding post 51 to move upward. When the protruding post 51 moves to the position of the upper adjusting groove 411, rotate the adjusting bracket 5 again so that the protruding post 51 is locked with the upper adjusting groove 411. In this way, the adjusting bracket 5 is positioned. The extended adjusting bracket 5 can protect the SPE post on the upper part of the panel 2 and prevent the SPE post from contacting the table and shaking. The multi-faceted design of the adjusting ring 42 can provide a stable gripping point when the positioning bracket 4 is engaged.
