DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] This specific embodiment is a water sample filtering device for ecological environment monitoring, and its structural diagram is as follows Figure 1-Figure 4 As shown, it includes a filter box 1, a water tank 3, a fixing structure and a pull-out assembly 6. The water tank 3 is arranged below the filter box 1. The water tank 3 and the filter box 1 are detachably connected. The upper surface of the filter box 1 has a liquid injection hole 12, and a sealing block 5 is threadedly installed at the liquid injection hole 12;

[0024] The bottom of the filter box 1 is provided with a liquid outlet, and the water tank 3 is connected to the threaded hole of the liquid outlet. A handle 2 is installed on the outer wall of the filter box 1. A pull-out assembly 6 is provided on the surface of the filter box 1 adjacent to the handle 2. Two groups of pull-out assemblies 6 are spaced side by side. The pull-out assembly 6 includes a pull-out frame 10 and a handle 9. The interior of the pull-out frame 10 is a hollow structure. A filter screen 11 is fixedly installed in the upper pull-out frame 10, and a sealing plate 8 is fixedly installed in the lower pull-out frame 10. The sealing plate 8 blocks the liquid outlet. The handle 9 is fixedly installed on the side wall of the pull-out frame 10, and a sealing strip 14 is provided on the outside of the pull-out frame 10. A limited position plug hole 13 is provided on the upper surface of the pull-out frame 10. A fixing mechanism 4 is fixedly installed on the outer wall of the filter box 1. The fixing mechanism 4 includes a fixing block 16 and a limiting plug rod 15. The fixing block 16 is fixedly connected to the outer wall of the filter box 1. The interior of the fixed block 16 is a hollow structure, and the limiting rod 15 extends from the top of the fixed block 16 to the bottom. The limiting rod 15 is located on the outer wall of the fixed block 16 and is fixedly installed with a connecting block 17. The bottom end surface of the connecting block 17 is fixedly connected to a spring.

[0025] A limiting block 18 is fixedly welded on the inner wall of the fixing block 16 . The upper surface of the limiting block 18 is fixedly connected to a spring, and the spring is movably sleeved on the outside of the limiting rod 15 .

[0026] Working principle: When in use, first open the sealing block 5 and pour the water sample into the filter box 1 from the liquid injection hole 12. After the water sample enters the filter box 1, it first passes through the filter screen 11 to filter impurities, and then flows into the water tank 3 along the liquid outlet hole at the bottom of the filter box 1. When the water sample is filtered, the lower pull-out component 6 can be slid into the filter box 1 so that the sealing plate 8 is flush with the liquid outlet hole to block it, preventing the filtered water sample in the water tank 3 from flowing back into the filter box 1. Then pull out the upper pull-out component 6 to clean the particulate impurities intercepted in the filter screen 11;

[0027] The pull-out assembly 6 is limited by a fixed structure, and the pulling operation method is to first pull up the limiting rod 15, and the bottom of the limiting rod 15 moves out of the limiting hole 13. After the limiting rod 15 moves up, the connecting block 17 moves up accordingly, and the bottom of the spring is fixedly connected to the limiting block 18, and then the spring is stretched. At this time, the pull-out frame 10 can be slid out from the inside of the filter box 1. Conversely, when the pull-out frame 10 slides into the filter box 1, the pull on the limiting rod 15 is released, and the spring resets and contracts to drive the connecting block 17 toward the limiting block 18, and then the bottom of the limiting rod 15 is inserted into the limiting hole 13 to complete the fixation. Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
