Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline technology, and in particular to a water conservancy pipeline with a stable connection. Background Technology

[0002] Water conservancy pipelines refer to pipeline systems used to transport water resources. They are widely used in urban water supply, farmland irrigation, industrial production, drainage and flood control, and other fields. Publication number CN216768781U discloses a water conservancy pipeline that achieves good performance through the coordination of the pipeline body, flanges, base layer, flame-retardant layer, wear-resistant layer, waterproof layer, anti-corrosion layer, first protective layer, second protective layer, and third protective layer. It has advantages such as corrosion resistance, wear resistance, and flame retardancy, improving the safety of water conservancy pipelines and meeting the needs of today's market. It enhances the practicality and usability of water conservancy pipelines and solves the problem of poor performance of previous water conservancy pipelines. However, this type of water conservancy pipeline is directly connected by flanges. When the water flow inside the pipeline is large, the connection may collapse downwards due to the lack of a stable support structure, leading to unstable connections and leakage at the pipe joints. Furthermore, unstable connections may cause friction or vibration between pipe materials, accelerating corrosion and wear, and reducing the normal service life of the water conservancy pipeline. Therefore, improvements are needed. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] Please see Figure 1-4This utility model provides a technical solution: a stable water conservancy pipeline, including a first connecting pipe 1, a first flange 2, a second connecting pipe 3, and a second flange 4. A lower support platform 5 is provided on the lower surface of the first connecting pipe 1. A fixing groove A6 is provided on the top of the lower support platform 5. An upper fixing platform 8 is provided on the top of the lower support platform 5. A fixing groove B9 is provided on the lower surface of the upper fixing platform 8. A groove 10 is symmetrically provided on the upper surface of the upper fixing platform 8. A threaded hole 11 is provided at the bottom of the groove 10. A threaded groove 12 is symmetrically provided on the top of the lower support platform 5. A threaded fixing pin 13 is threadedly connected to the threaded hole 11 and the threaded groove 12. A sliding groove 14 is symmetrically provided on the top of the lower support platform 5. A sliding rod 15 is symmetrically fixed on the lower surface of the upper fixing platform 8. The threaded fixing pin 13 securely fixes the first connecting pipe 1, the first flange 2, the second flange 4, and the second connecting pipe 3 between the fixing groove A6 and the fixing groove B9, improving the support and stability of the connected water conservancy pipelines, thus making the connection of the water conservancy pipeline more stable.

[0025] Please see Figure 2-4 The second flange 4 is installed between the fixed groove A6 and the fixed groove B9. The slide rod 15 is slidably connected to the slide groove 14. The first flange 2 and the second flange 4 are fixed between the fixed groove A6 and the fixed groove B9. The slide rod 15 slides in the slide groove 14. The bottom of the lower support platform 5 is fixedly installed with a base 7. The top of the threaded fixing pin 13 is fixedly installed with an auxiliary protruding rod 16. The base 7 increases the contact area of ​​the bottom of the lower support platform 5, making the lower support platform 5 stable on the contacted ground surface or soil. The surface of the threaded fixing pin 13 is fixedly connected with a fastening pad 17. The fastening pad 17 is made of rubber. The rubber fastening pad 17 makes the threaded fixing pin 13 more tightly fixed in the threaded hole 11 and the threaded groove 12. The upper fixed platform 8 is symmetrically fixedly installed with protruding plates 18 on both sides. The protruding plates 18 are rounded. The protruding plates 18 help the workers to lift the upper fixed platform 8 upward.

[0026] Example 2

[0027] Please see Figure 2 , 5 The first flange 2 has evenly spaced mating grooves 19 on its surface near the second flange 4. The second flange 4 has evenly fixed mating blocks 20 on its surface near the first flange 2. When the first connecting pipe 1 and the second connecting pipe 3 are connected, the mating blocks 20 are quickly inserted into the mating grooves 19 to quickly mate the first flange 2 and the second flange 4. The mating blocks 20 are inserted into the mating grooves 19 and have rounded corners. One end of the second flange 4 is fixedly fitted with a mating inner ring 21. When the first flange 2 and the second flange 4 are mated, the mating inner ring 21 can be inserted into the interior of the first flange 2.

[0028] Working principle: When the operator connects and fixes the first connecting pipe 1 and the second connecting pipe 3, first unscrew the threaded fixing pin 13. The operator then uses the convex plate 18 to lift the upper fixing platform 8 upwards. Subsequently, the sliding rod 15 slides in the sliding groove 14 until the gap between the fixing groove A6 and the fixing groove B9 is larger than the diameter of the second flange 4. Then, other operators lift the second connecting pipe 3 into the fixing groove A6. By pushing the second connecting pipe 3, the second flange 4 slides inside the fixing groove A6 until the inner ring 21 of the first flange 2 enters the interior of the first flange 2. Then, the mating block 20 is inserted into the mating groove 19. Finally, the operator can connect the first flange 2 and the second flange 3. After fixing the flange 4, the upper fixing platform 8 is placed on top of the lower support platform 5. Similarly, the slide rod 15 slides inside the slide groove 14 until the upper fixing platform 8 contacts the lower support platform 5. Then, the worker uses the rotating auxiliary protrusion 16 to fix the threaded fixing pin 13 inside the threaded hole 11 and the threaded groove 12. Thus, the threaded fixing pin 13 makes the first connecting pipe 1, the first flange 2, the second flange 4 and the second connecting pipe 3 more firmly fixed between the fixing groove A6 and the fixing groove B9, which improves the support and fixation between the connecting water pipes, making the connection of the water pipes more stable, avoiding water leakage, wear and other problems at the connection of the water pipes, and improving the service life.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
