[0018] Please refer to Figures 1-4The utility model provides a technical scheme: a kind of farmland water conservancy irrigation anti-blocking connecting pipe, including connecting pipe body 1, the middle of connecting pipe body 1 top is equipped with liquid inlet 2, liquid inlet 2 and connecting pipe body 1 are integral structure, the inside of liquid inlet 2 is equipped with flow guide cylinder 3, the upper end of flow guide cylinder 3 both ends is open structure, conical filter screen 4 is embedded in the inside of flow guide cylinder 3, conical filter screen 4 is uniformly equipped with several flow guide vanes 5, and the top of liquid inlet 2 is fixedly installed with connecting seat 6 along mouth, butt flange 7 is fixedly welded on the top of connecting seat 6, and both sides of flow guide cylinder 3 are equipped with positioning rod 8, the bottom of positioning rod 8 is fixedly welded with the outer wall of flow guide cylinder 3 by connecting block, the top of positioning rod 8 is fixedly welded with horizontally distributed embedded block 9, the inner wall of both sides of connecting seat 6 along mouth is equipped with embedded mouth, and the structure of embedded block 9 is matched, spring lock 10 is movably equipped on the inner wall of both sides of connecting seat 6 along mouth, spring lock 10 and the embedded mouth position on the inner wall of connecting seat 6 along mouth are corresponding, the liquid inlet 2 of this structure is connected with external water supply pipe by using butt flange 7 after fixing connecting seat 6 on top, so that liquid inlet 2 ensures that the water flow of connecting pipe body 1 is smoothly entered, and the conical filter screen 4 embedded in the inside of flow guide cylinder 3 and the flow guide vanes 5 evenly distributed in its inside jointly act, so that water flow can be effectively dispersed and guided when passing through flow guide cylinder 3, reduce the concentrated impact of impurities on single area, thereby reduce the risk of blockage, and do not affect water flow speed and pressure, simultaneously, flow guide cylinder 3 is accurately matched with the embedded mouth on the inner wall of both sides of connecting seat 6 along mouth by positioning rod 8 on both sides and embedded block 9 fixedly welded on its top, ensure the stable installation of flow guide cylinder 3 in liquid inlet 2, also facilitate quick disassembly and cleaning and maintenance, and spring lock 10 can be quickly locked after embedded block 9 is inserted into corresponding embedded mouth, as a whole, connecting pipe body 1 realizes efficient filtration by the close cooperation between the components arranged in the inside, also greatly facilitates maintenance work, solves the problem of traditional filter screen being easily blocked and inconvenient to clean in the prior art, significantly improves the stability and maintenance efficiency of the system, effectively reduces the workload of user cleaning and maintenance, provides a more reliable and efficient solution for farmland water conservancy, the bottom of conical filter screen 4 is equipped with horizontal support 12, and connecting column 13 is connected on the top of horizontal support 12 by screw thread interface, and flow guide vane 5 is connected around connecting column 13 by connecting piece, the structure of each flow guide vane 5 can be evenly distributed and firmly fixed in specified position, so as to ensure that water flow can be effectively dispersed and guided, that is, when water flow passes through conical filter screen 4, flow guide vane 5 guides water flow to form ideal flow path, reduces the concentrated impact on single area, reduces the risk of blockage, and does not significantly affect water flow speed and pressure, simultaneously, since flow guide vane 5 is connected with connecting column 13 by connecting piece, this provides great convenience for subsequent cleaning and maintenance, only needs to be simply disassembled to quickly clean or replace parts,The guide vane 5 is in a wavy flat strip structure, and the guide vane 5 is vertically distributed inside the conical filter screen 4. The structure of the guide vane 5 can effectively divide and guide the water flow when passing through the conical filter screen 4, form a plurality of smaller flow channels, increase the contact area of the water flow and the filter screen, and the wavy shape can help to disturb the straight flow of the water flow, so that the water flow is more uniformly dispersed on the surface of the entire conical filter screen 4. The bottom end of the guide cylinder 3 is provided with a plurality of guide pipes 11, and the guide pipes 11 are inclined outward. This structure can make the water flow filtered by the conical filter screen 4 more uniformly and efficiently guided out through the guide pipes 11. The guide pipes 11 can effectively disperse the water flow, avoid the water directly impacting the bottom of the middle of the connecting pipe body 1 or causing local area water flow overload, thereby reducing the water flow resistance and preventing the possibility of secondary blockage. The connecting seat 6 is also provided with a plurality of guide grooves 14 on the inner wall along the mouth, and the inner wall of the guide groove 14 is in a circular arc structure. This structure can make the water flow preliminarily guided and dispersed through the guide groove 14 before entering the connecting pipe body 1, ensure that the water flow flows more smoothly into the guide cylinder 3, and the guide groove 14 can also effectively reduce the water flow resistance and avoid energy loss caused by sudden turning or impact of the water flow, so that the water flow can flow more smoothly through the connecting seat 6 into the subsequent filtering assembly. The inner end of the elastic lock 10 is hinged to the inner wall of the connecting seat 6 through a rotating pin, and a spring sheet is further connected between the back side of the elastic lock 10 and the inner wall of the connecting seat 6. When the guide cylinder 3 is inserted into the embedding hole of the connecting seat 6 through the embedding block 9 at the top end of the positioning rod 8, the elastic lock 10 automatically rotates inward and tightly presses the embedding block 9 due to the action of the spring sheet, which ensures the stable installation of the guide cylinder 3 in the liquid inlet 2. When cleaning or maintenance is needed, only an outward force needs to be applied to the elastic lock 10 to make it rotate around the rotating pin and compress the spring sheet, thereby releasing the embedding block 9 and achieving quick disassembly.

[0019] Working principle: when using the anti-blocking connecting pipe for farmland water conservancy irrigation, first, connect the external water supply pipe to the top of the connecting seat 6 through the butt flange 7. The water flow is then preliminarily guided and dispersed through the guide grooves 14 on the inner wall of the connecting seat 6 along the mouth, enters the liquid inlet 2, and flows smoothly into the guide cylinder 3. Then, the water flow passes through the conical filter screen 4, and the uniformly distributed guide vanes 5 guide the water flow to form an ideal flow path, so that the water flow can be effectively divided and guided. The filtered water is more uniformly and efficiently guided out through the outwardly inclined guide pipes 11 arranged at the bottom end of the guide cylinder 3. When cleaning or maintenance of the guide cylinder 3 and its internal components is needed, an outward force can be applied to make the elastic lock 10 rotate around the rotating pin and compress the spring sheet, thereby releasing the embedding block 9 and achieving quick disassembly. The embedding block 9 at the top end of the positioning rod 8 is fixed by welding and precisely fits the embedding hole on the inner wall of the connecting seat 6 along the mouth, which ensures the stable installation of the guide cylinder 3 in the liquid inlet 2, thereby completing a series of work.
