During the construction process, it is necessary to formulate corresponding construction plans according to the characteristics of different environments. "Water conservancy river channel construction" refers to the use of certain construction methods and techniques to carry out civil engineering, installation and maintenance work in rivers, lakes, reservoirs and other waters or hydrogeological conditions in accordance with the requirements of water conservancy project design. Its purpose is to improve the efficiency of water resource utilization, prevent and control water disasters, ensure flood control safety, provide water resource supply and improve the water environment. During water conservancy construction, in order to remove sewage or heavy rain precipitation, pumps will be installed to extract and discharge sewage or rainwater to avoid waterlogging.

[0032] Working principle: When the filter frame 1 is in use, the filter frame 1 is in use according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 7 , suction can be generated in the filter frame 1 through the suction pipe 2, and large floating garbage can be blocked by the blocking grid 3. At this time, the sewage is guided by the guide plate 4, and the filter partition 5 can filter the impurities and garbage in the sewage for a second time and then discharge it through the suction pipe 2. When the filter frame 1 is filtering, the reciprocating screw rod 63 can drive the moving block 64 to rotate through the driving motor 62, which is convenient for the driven gear 71 to rotate synchronously. Through the rotation of the driven gear 71, the first pulley 73 can drive the second pulley 74 to rotate, which is convenient for the first pulley 73 to drive the second pulley 74 to rotate. The second connecting column 75 drives the adsorption magnetic plate 76 to move the filtered matter accumulated on the surface of the guide plate 4. At this time, the adsorption magnetic plate 76 can adsorb the metal in the filtered matter. At the same time, the rotation of the connecting transmission shaft 72 can synchronously drive the plug-in plate 111 to rotate, so as to conveniently drive the cleaning scraper 115 to rotate along the surface of the filter partition 5 to scrape the filtered matter on the surface of the filter partition 5. At the same time, the elastic force of the third spring 113 itself can conveniently push the limiting plate 114 and the cleaning scraper 115, so as to facilitate the cleaning scraper 115 to conflict with the surface of the filter partition 5. When the adsorption magnetic plate 76 is toggled to drive the adsorbed metal to move to the upper part of the filter frame 1, the rotation of the reciprocating screw rod 63 can make the moving block 64 reciprocate along the surface of the reciprocating screw rod 63. Through the fixed movement of the reciprocating screw rod 63, the first connecting column 65 can drive the scraper plate 66 to move, and the scraper plate 66 can push the metal adsorbed on the surface of the toggle adsorption magnetic plate 76 to the surface of the fixed collecting plate 8 for winding. When the moving block 64 moves, the guide block 67 can drive the pushing rod 68 to slide along the surface of the guide rod 91. When 98 pushes the surface of the moving push plate 103, the driving fixed column 101 can drive the moving connecting sleeve 92 and the reset pushing plate 93 to slide along the surface of the guide rod 91, so that the moving push plate 103 can push the metal on the surface of the fixed collecting plate 8, so that the metal can be accumulated. At the same time, the elastic force of the second spring 102 itself can make it convenient for the moving push plate 103 to keep in contact with the surface of the fixed collecting plate 8. The above is the entire working principle of the present invention.

[0033] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
