Among numerous water conservancy projects, water pipelines are particularly widely used. They are commonly employed in long-distance water transmission, urban water supply and drainage systems, and farmland irrigation. After extracting water resources from water sources, these pipelines construct a vast pipeline network to safely and efficiently transport precious water resources to various water-using terminals, meeting the needs of people's daily lives and industrial and agricultural production.

[0003] In the current field of pipeline connection, the commonly used welding technology often fails to ensure a long-term and stable sealing effect. To solve this problem, existing methods usually involve interlocking pipes and combining welding technology with the use of flanges to enhance the sealing performance of the pipes. However, in the actual pipeline installation process, especially when facing complex construction environments and dynamic stress changes experienced during pipeline operation, these joints often become loose or even cracked. Therefore, a leak-proof water conservancy pipeline for water conservancy projects is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a leak-proof water pipe for water conservancy projects, comprising a mounting base 1, two pipe bodies 3, and two flanges 16. The mounting base 1 has sliding grooves 5 on its top left and right ends, and fixing nuts 6 are slidably connected to the inner sides of multiple sliding grooves 5. The sliding grooves 5 are located on both sides of the mounting base 1, and the fixing nuts 6 inside are used for subsequent connection and reinforcement. Adjusting plates 4 are slidably connected to the top left and right ends of the mounting base 1, and clamping plates 8 are fixedly connected to the top of each of the two adjusting plates 4. The two pipe bodies 3 are respectively placed on the top of the adjusting plates 4 and clamped by the clamping plates 8. Screws 9 are threadedly connected to the front and rear sides of the top of the two clamping plates 8. The bottom end of the screw 9 penetrates the top of the adjusting plate 4 and is threadedly connected to the inner side of the fixing nuts 6. A fixed plate 10 is slidably connected to the outer wall. The clamping plate 8 and the adjusting plate 4 are connected by a screw 9, which passes through the adjusting plate 4 and is connected to the fixing nut 6. The adjusting plate 4 can not only accurately position the pipe body 3, but also prevent the bending force from being concentrated on the connected pipe body 3 ports, effectively preventing breakage. Multiple connection holes 19 are opened on the adjacent side of the two flanges 16. The inner side of the multiple connection holes 19 is threaded with a connecting bolt 20. An installation mechanism 2 is set between the two pipe bodies 3. The installation mechanism 2 is used to seal the connection of the pipe body 3. Multiple rubber strips 11 are fixedly connected between the clamping plate 8 and the adjusting plate 4. The rubber strips 11 can buffer the pipe body 3, reduce wear and shaking. The multiple rubber strips 11 are arranged at equal intervals.

[0032] Specifically, the top left and right ends of the mounting base 1 are designed with sliding grooves 5, and multiple fixing nuts 6 are installed on the inner side of these sliding grooves 5. Adjusting plates 4 are also slidably connected to the top left and right ends of the mounting base 1. The two pipes 3 are placed on the top of the adjusting plates 4 and clamped by clamping plates 8 to ensure the stability and correct position of the pipes 3. The clamping plates 8 and the adjusting plates 4 are connected by screws 9, which pass through the adjusting plates 4 and are connected to the fixing nuts 6, ensuring the stability of the entire structure. The adjusting plates 4 can not only accurately position the pipes 3, but also prevent the force generated by bending from being concentrated on the ends of the interconnected pipes 3, thereby effectively preventing breakage. The connecting holes 19 on the flange 16 tightly connect the two pipes 3 together through connecting bolts 20. Multiple rubber strips 11 are fixed between the clamping plates 8 and the adjusting plates 4. These rubber strips 11 can buffer the pipes 3, reduce wear and shaking, and improve the service life of the pipes 3. The multiple rubber strips 11 are arranged at equal intervals to ensure the uniformity of the buffering effect.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The installation mechanism 2 includes an installation ring 201, which is fixedly connected to the outer wall of the left pipe body 3 and to the outer wall of the connecting end of the pipe body 3. The outer wall of the installation ring 201 has extrusion grooves 202 around its perimeter. Each extrusion groove 202 has a T-shaped opening. Limiting strips 203 are slidably connected to the inner sides of multiple extrusion grooves 202. Multiple sealing strips 204 are fixedly connected to the opposite sides of the multiple limiting strips 203. The limiting strips 203 and the multiple sealing strips 204 are integrally formed and are all made of rubber. A fixing ring 205 is fixedly connected to the inner side of the right pipe body 3. The inner circumference of the ring 205 is fixedly connected with the extrusion block 206. The ring 205 and the extrusion block 206 are integrally formed. The outer shape of the extrusion block 206 corresponds to the T-shaped groove. When the two tubes 3 are connected to each other, the extrusion block 206 will extrude the limiting strip 203 in the extrusion groove 202, thereby causing the multi-section sealing strip 204 to be extruded to each other and fit against the inner wall of the tube 3, further improving the sealing performance of the connection between the tubes 3 and achieving a good leak-proof effect. The installation mechanism 2 also includes two indicator plates 207, which are fixedly connected to the top of the outer wall of the tube 3.

[0034] Specifically, the mounting ring 201 is connected to the outer wall of the left-side pipe 3. Multiple extrusion grooves 202 are evenly distributed around the outer wall of the mounting ring 201. These extrusion grooves 202 are designed as T-shaped notches to accommodate specific structural requirements. Multiple limiting strips 203 are connected within these T-shaped notches. The limiting strips 203 and the multi-section sealing strips 204 are manufactured as a single piece, ensuring structural integrity and sealing strip reliability. Both components are made of rubber to provide necessary elasticity and durability. The fixing ring 205 and the extrusion block 206 also adopt a single-piece design, ensuring structural robustness and precise fit of the extrusion block 206. The external shape of the extrusion block 206 matches the T-shaped notches. When the two pipes 3 are connected, the extrusion block 206 applies pressure to the limiting strips 203 in the extrusion grooves 202, thereby pushing the multi-section sealing strips 204 to press against each other, tightly fitting the inner wall of the pipe 3. This design significantly improves the sealing performance of the pipe connections, effectively preventing leakage and ensuring system reliability.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The mounting base 1 is fixedly connected to the front and rear sides with connecting plates 12. The top of the connecting plate 12 is provided with screw holes 13. The mounting base 1 is connected to the foundation through the connecting plate 12, and the bolts 14 are fixed to the ground through the screw holes 13 to improve the firmness of the mounting base 1. The screw holes 13 are threaded with bolts 14. The inner diameter of the screw holes 13 is matched with the diameter of the bolts 14. The top of the outer wall of the right pipe body 3 is equipped with a pressure sensor 7. The pressure sensor 7 can monitor the flow and pressure of the internal liquid in real time. Multiple reinforcing plates 15 are fixedly connected to the opposite side of the two flanges 16. Wear-resistant rings 17 are fixedly connected to the outer wall of the flanges 16. The outer wall of the wear-resistant rings 17 is provided with grooves 18.

[0036] Specifically, the mounting base 1 is securely connected to the foundation via the connecting plate 12, and the bolts 14 can pass through the bolt holes 13 and be firmly fixed to the ground, improving the stability of the mounting base 1. The pressure sensor 7 can monitor the flow and pressure of the internal liquid in real time, ensuring the stable operation of the system. In addition, multiple reinforcing plates 15 are fixed to the opposite sides of the two flanges 16, which enhance the structural strength of the flanges 16.

[0037] Working principle: First, the two tubes 3 are placed on the top of the adjusting plate 4 and clamped by the clamping plate 8. The clamping plate 8 is connected to the adjusting plate 4 by the screw 9 and passes through the adjusting plate 4 to connect with the fixing nut 6. The fixing nut 6, together with the fixing piece 10, achieves a tight connection and fixation of the clamping plate 8, the adjusting plate 4, the tubes 3 and the mounting base 1. The adjusting plate 4 can not only accurately position the tubes 3, but also prevent the bending force from being concentrated on the interconnected tubes 3.

[0038] Furthermore, the limiting strip 203 and the multi-section sealing strip 204 are integrally formed, and the fixing ring 205 and the extrusion block 206 are integrally formed. When the two tubes 3 are connected to each other, they are interlocked according to the indicator plate 207 on the two tubes 3. The extrusion block 206 is inserted into the extrusion groove 202. The limiting strip 203 in the extrusion groove 202 is extruded by the extrusion block 206, so that the multi-section sealing strip 204 is extruded to each other and fits against the inner wall of the tube 3.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
