Description

Technical Field

[0001] The utility model relates to the technical field of water body ecological restoration, in particular to a sample filtering device used for water ecological restoration. Background Art

[0002] Water body ecological restoration, also known as "water body ecological restoration", is a process of partial or complete restoration of damaged, degraded or destroyed water body ecosystems using relevant technical means based on ecological principles, that is, an ecologically integrated restoration and management process. In the process of water body ecological restoration, it is necessary to regularly sample and test the restored water body so as to know the restoration results.

[0003] After the sample water solution is taken out from the restoration water body, the water will contain more impurities and aquatic plants. The impurities and aquatic plants will affect the detection of the sample, so it needs to be filtered. During the filtration process, traditional filtration uses a filter. Too many impurities or aquatic plants in the sample water will cause blockage, and the sample water solution cannot be filtered quickly. Therefore, a sample filtration device for water ecological restoration is proposed. Utility Model Content

[0011] Preferably, the telescopic assembly comprises a telescopic cylinder fixedly mounted on the top side of the filter base, and an output end of the telescopic cylinder is fixedly connected to the bottom side of the bottom support plate.

[0012] Preferably, position blocks are fixedly installed on both sides of the support rod, and the two position blocks block the upper position of the movable sleeve plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the sample filtering device for water ecological restoration takes out a certain sample solution from the restored water solution and pours it into the filter barrel. The provided filtering assembly can realize graded filtration, thereby avoiding the problem that a single filter screen is easily blocked during filtration. The filtered aqueous solution will fall into the sample holding cup for collection;

[0022] Specifically, the telescopic component includes a telescopic cylinder 9 fixedly installed on the top side of the filter base 1, and the output end of the telescopic cylinder 9 is fixedly connected to the bottom side of the bottom support plate 4. During the filtration process, the telescopic cylinder 9 on the telescopic component is started to run, driving the bottom support plate 4 to move downward. Under the action of gravity, the sample holding cup 5 will also move downward.

The rotation of the driving shaft 14 can drive the worm 15 on the rotating driving assembly to rotate, thereby driving the worm wheel 16 to rotate, and driving the rotating shaft 12 to rotate. The stirring plate 13 will stir the sample aqueous solution. By stirring, impurities or aquatic plants will not accumulate and cause blockage. At the same time, the filtration speed of the aqueous solution can be increased in a phased manner, avoiding the problem of slow filtration effect caused by blockage. By slowly moving downward, the repaired aqueous solution sample can be filtered in the filter barrel 6. When the bottom support plate 4 moves to the bottom, the sample solution is also filtered, and the sample can be directly taken out and placed in the water cup 5, which is more convenient.
