[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 2The utility model provides an embodiment: a pipeline connection device for water conservancy projects, including a main pipeline 1, which is made of corrosion-resistant and wear-resistant hard materials, such as steel or corrosion-resistant alloys, to ensure that it can maintain good performance in various environments. A connecting pipe 2 is arranged at the left end of the main pipeline 1, and an extension pipe 3 is fixedly connected to the right end of the connecting pipe 2. Positioning components are arranged on the four sides of the outside of the extension pipe 3. The positioning components include multiple fixing blocks 4, and the inner side walls of the multiple fixing blocks 4 are respectively fixedly connected to the outside of the extension pipe 3, so that the fixing blocks 4 and the extension pipe 3 can form a stable whole.

[0033] refer to Figure 2-Figure 3 The extension tube 3 is slidably connected to the inside with sliding plates 5 all around, and the sliding plates 5 can be restricted by the extension tube 3. The outer wall of the sliding plate 5 is fixedly connected with a ball 6, and the outside of the ball 6 is slidably connected to the inner wall of the fixed block 4. A spring 7 is arranged all around the outside of the extension tube 3, and the spring 7 is restricted by the extension tube 3. One end of the spring 7 is fixedly connected to one side of the sliding plate 5, and the other end of the spring 7 is fixedly connected to the inner wall of one side of the extension tube 3. The movement of the sliding plate 5 can squeeze the spring 7 so that the spring 7 is deformed.

[0034] Positioning grooves 8 are provided around the left end of the main pipe 1. The outside of the fixed block 4 is slidably connected to the inner wall of the positioning groove 8. The sliding of the fixed block 4 on the inner wall of the positioning groove 8 can improve the connection effect. The outside of the ball 6 is engaged with the inner wall of the positioning groove 8. The engagement of the ball 6 with the positioning groove 8 can make the main pipe 1 and the connecting pipe 2 preliminarily connected. The outside of the connecting pipe 2 is rotatably connected to a rotating rod 9. Both sides of the rotating rod 9 are rotatably connected to rotating rings 10. The rotating ring 10 can be rotated through the rotating rod 9. An extension block 11 is fixedly connected to the bottom of one of the rotating rings 10.

[0035] refer to Figure 4The front end of the extension block 11 is fixedly connected with a connecting block 12, and the connecting block 12 can be limited by the extension block 11. The bottom of another rotating ring 10 is fixedly connected with an extension block 2 13. The outside of the connecting block 12 is movably connected to the through hole of the extension block 2 13. The left end of the extension block 2 13 is slidably connected with a control rod 14, so that the extension block 2 13 can limit the control rod 14. The outside of the control rod 14 is engaged with the through hole at the left end of the connecting block 12. By limiting the connecting block 12 through the control rod 14, the two rotating rings 10 can be limited at the connection between the main pipeline 1 and the connecting pipe 2. Thereby, the main pipeline 1 and the connecting pipe 2 can be connected to each other. The outside of the control rod 14 is fixedly connected with a moving block 15, so that the control rod 14 can control the moving block 15 to move. The outside of the moving block 15 is slidably connected to the inner wall of the extension block 13, so that the moving block 15 can be restricted by the extension block 13. The outside of the control rod 14 is sleeved with a spring 16, one end of the spring 16 is fixedly connected to the inner wall of one side of the extension block 13, and the other end of the spring 16 is fixedly connected to one side of the moving block 15. The moving block 15 can push the spring 16 so that the spring 16 is squeezed.

[0036] refer to Figure 5 A sealing assembly is provided on the inner wall of the rotating ring 10, each sealing assembly includes a plurality of springs three 17, and the plurality of springs three 17 are arranged inside the rotating ring 10. A limiting block 18 is slidably connected inside the rotating ring 10, and the limiting block 18 can be limited by the rotating ring 10. A sealing block 19 is fixedly connected to the inner side wall of the limiting block 18. The sealing block 19 is made of rubber material, and the inner side walls of the sealing block 19 are respectively fitted with the outside of the main pipe 1 and the connecting pipe 2, so that the main pipe 1 and the connecting pipe 2 can be sealed.

[0037] Working principle: when it is necessary to connect the pipes, the main pipe 1 and the connecting pipe 2 are inserted together, and the extension pipe 3 will enter the inner wall of the main pipe 1, and the fixing block 4 will slide on the inner wall of the positioning groove 8. At this time, the ball 6 is in an extruded state. When the extension pipe 3 completely enters the inner wall of the main pipe 1, the spring 17 will push the sliding plate 5 and then push the ball 6, so that the ball 6 and the circular hole on the inner wall of the positioning groove 8 are completely fitted together, completing the first positioning between the main pipe 1 and the connecting pipe 2. At this time, the rotating ring 10 is rotated again to make the two rotating rings 10 close together for fixing. When they are close together, the sealing block 19 will press against the connection between the main pipe 1 and the connecting pipe 2. At this time, the sealing block 19 can push the limiting block 18 to squeeze the spring three 17 so that the spring three 17 is deformed to generate elastic potential energy so that the sealing block 19 can fit tightly to the connection between the main pipeline 1 and the connecting pipe 2 to complete the sealing. Finally, the connecting block 12 is moved closer between the rotating rings 10 to be at the through hole of the extension block two 13, and the connecting block 12 can push the rounded corner of one corner of the control rod 14, so that the control rod 14 drives the moving block 15 to squeeze the spring two 16. When the through hole of the connecting block 12 is revealed, the spring two 16 will reset so that the moving block 15 drives the control rod 14 to reset and engage the through hole of the connecting block 12, thereby completing the installation.

[0038] When disassembly is required, pull the control rod 14. At this time, the pulling of the control rod 14 can withdraw the through hole of the connecting block 12. At this time, the two rotating rings 10 are separated. Then, the main pipe 1 and the connecting pipe 2 are pulled hard, so that the ball 6 slides out of the circular hole of the positioning groove 8, thereby completing the separation between the main pipe 1 and the connecting pipe 2.

[0039] Finally, it should be noted that the above 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, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
