[0020] like Figure 1 - Figure 3 As shown, in this embodiment, in order to avoid the problem of clogging of the water pump 1 when pumping water to the farmland for irrigation through the water pumping pipe 3 through the filtering mechanism 4, a group of left-right symmetrical positioning grooves 5 are opened on the inner wall of the bottom end of the water pumping pipe 3, and a group of front-back symmetrical clamping grooves 6 are also opened on the inner wall of the bottom end of the water pumping pipe 3, a plurality of filtering water inlet holes 8 are opened on the outer wall and bottom surface of the outer cylinder 7, and the four sides of the top surface of the outer cylinder 7 are respectively opened with thread grooves 9, the inner filter screen cylinder 10 is located in the outer cylinder 7, and the top surface of the inner filter screen cylinder 10 is fixedly installed with a fixing ring 11, and the four sides of the top surface of the fixing ring 11 are respectively opened with mounting holes 12 corresponding to the thread grooves 9, and the bolt 1 3 is inserted and installed in the installation hole 12 and is threadedly connected with the thread groove 9, the butt pipe 14 is fixedly installed on the top surface of the fixing ring 11, and the butt pipe 14 is inserted and installed in the bottom end of the water pumping pipe 3, and a positioning block 15 corresponding to the positioning groove 5 is fixedly installed on the outer wall of the butt pipe 14, and the positioning block 15 is inserted and installed in the positioning groove 5, and a group of front and rear symmetrical grooves 16 are also opened on the outer wall of the butt pipe 14, and a retaining ring 17 is fixedly installed in the groove of the groove 16, and a compression spring 18 is fixedly installed at the bottom of the groove 16, and a clamp 19 is fixedly installed on the outer end of the compression spring 18, and the clamp 19 passes through the retaining ring 17 and is located in the clamping groove 6;

[0021] The specific operating principle of the filtering mechanism 4 is as follows: before the water pump 1 pumps out the water in the river or canal through the water pumping pipe 3 installed on the input end and transports the water to the farmland through the irrigation pipe 2 installed on the output end for irrigating the crops, the filtering mechanism 4 is installed on the bottom end of the water pumping pipe 3. During installation, the inner filter screen cylinder 10 is placed in the cylinder of the outer cylinder 7, and the mounting holes 12 opened on the four sides of the top surface of the fixing ring 11 installed on the top surface of the inner filter screen cylinder 10 are aligned with the threaded grooves 9 opened on the four sides of the top surface of the outer cylinder 7, and then the bolts 13 are inserted through the mounting holes 12 and threadedly connected with the threaded grooves 9, so that the inner filter screen cylinder 10 can be installed and fixed inside the outer cylinder 7, and then the fixing ring 11 is installed on the top surface of the inner filter screen cylinder 10. The butt joint pipe 14 installed on the surface is inserted into the bottom end of the water pumping pipe 3. During the insertion of the butt joint pipe 14, the positioning blocks 15 installed on both sides of the outer wall of the butt joint pipe 14 are aligned with the positioning grooves 5 opened on the inner wall of the bottom end of the water pumping pipe 3, and the positioning blocks 15 are inserted into the grooves of the positioning grooves 5. During this process, the protruding clamps 19 on both sides of the butt joint pipe 14 will be squeezed by the inner wall of the water pumping pipe 3, and the clamps 19 will move into the grooves 16 opened on the outer wall of the butt joint pipe 14 through the retaining ring 17, and force the compression spring 18 installed at the bottom of the groove 16 to retract, and the clamps 19 will press against the inner wall of the water pumping pipe 3 under the reverse elastic force of the compression spring 18 until the butt joint pipe 14 is fully inserted into the water pumping pipe 3. The bottom end of the water pipe 3 is inserted into the positioning block 15 into the positioning groove 5. At this time, the clamp 19 will lose the resisting pressure, and the compression spring 18 will stretch and recover, and push the clamp 19 outward through the retaining ring 17 until the clamp 19 is clamped into the corresponding clamping groove 6 opened on the inner wall of the bottom end of the water pumping pipe 3. In this way, the filter mechanism 4 can be clamped and installed at the bottom end of the water pumping pipe 3. When the water pumping pipe 3 is immersed in water and pumping water, water will enter the outer cylinder 7 through the filter water inlet hole 8 opened on the outer wall of the outer cylinder 7, and the larger impurities in the water can be filtered and blocked through the filter water inlet hole 8. Because the inner filter mesh cylinder 10 is installed in the outer cylinder 7, the water in the outer cylinder 7 is filtered through the filter water inlet hole 8. Smaller impurities will be further filtered outside the outer cylinder 7, thereby preventing impurities in the water from being drawn into the pumping pipe 3. Finally, the filtered water will be pumped out through the pumping pipe 3, so that the filtering mechanism 4 can effectively prevent the impurities in the water from clogging the pipeline and damaging the pump 1 when the device is used for pumping irrigation, so as to play an anti-clogging protection role for the pumping pipe 3 during irrigation, thereby ensuring the irrigation effect and efficiency of the farmland water conservancy project, and after the irrigation is completed, it is also convenient to remove the filtering mechanism 4 from the bottom end of the pumping pipe 3 for disassembly, cleaning or replacement, so as to ensure that the mechanism can play a normal anti-clogging protection role for the pumping pipe 3 during irrigation.

[0022] The above description 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, various improvements may be made to the present invention and its components may be replaced by equivalents, or some of its technical features may be replaced by equivalents without departing from the scope of the present invention. All that is within the spirit and principles of the present invention should be included in the protection scope of the present invention.
