Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a water conservancy tunnel pumping pipeline. Background Art

[0002] Water conservancy tunnels play an important role in modern water conservancy projects and are key infrastructure for realizing functions such as rational allocation of water resources, flood control and drainage, and hydropower development. During the operation of a water conservancy tunnel, the pumping operation is an extremely important link, which is related to the timely removal of accumulated water in the tunnel, ensuring the safety of the tunnel structure and the normal operation of equipment. As the core component of the pumping operation in a water conservancy tunnel, the performance of the pumping pipeline directly affects the efficiency and stability of the pumping work and plays a decisive role in the reliable operation of the entire water conservancy tunnel system.

[0003] In the existing technology of water conservancy tunnel pumping pipelines, the connection stability between pipelines is a key issue. Traditional pipeline connection methods usually rely only on simple socketing or welding. When using the socketing method, during long-term pumping, under the influence of water flow impact, vibration, and external forces generated by the complex geological environment in the tunnel, the pipeline connection is prone to looseness. This is because the socketing connection cannot effectively limit the relative displacement between pipelines in all directions, and the force generated by the water flow impact will gradually increase the gap at the interface, resulting in connection failure, which will not only reduce the pumping efficiency but may also cause leakage problems and damage to the tunnel structure. Although the welding connection enhances the connection strength to a certain extent, in actual construction, it is difficult to fully guarantee the welding quality, and there is a risk of welding defects. Moreover, once a problem occurs at the welding point, the repair is difficult and requires a large amount of manpower, material resources, and time. In view of this technical problem, this application proposes a water conservancy tunnel pumping pipeline. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a water conservancy tunnel pumping pipeline is proposed. The limiting ring and the first limiting groove cooperate with each other to initially ensure the connection stability. The limiting ring and the second limiting groove further play a role in positioning and stabilizing the connection between the pipe body and the pipe sleeve. The disc springs arranged on the outer wall of the pipe body can elastically deform to absorb the impact force when impacted by water flow, and the tungsten carbide coating applied to the outer wall of the protective sleeve on its outer periphery enhances the overall impact resistance and wear resistance.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A water pumping pipe for a water conservancy tunnel includes a pipe body, a butterfly spring is provided on the outer wall of the pipe body, a protective sleeve is fixedly connected to the outer periphery of the butterfly spring, the protective sleeve is slidably connected to the outer wall of the pipe body, a limit groove 1 and a limit groove 2 are provided at both the left and right ends of the outer wall of the pipe body, a pipe sleeve is provided on the left side of the outer wall of the pipe body, and a fixing frame 1 and a fixing frame 2 are connected to the rear end of the pipe sleeve through a connecting component, the fixing frame 1 and the fixing frame 2 are connected by the fixing component.

[0007] Furthermore, the connecting assembly includes a limiting sleeve one located at the rear end of the tube sleeve, a limiting sleeve two rotatably connected to the bottom end of the limiting sleeve one, the limiting sleeve one being fixedly connected to the front end of the fixing frame one, and the limiting sleeve two being fixedly connected to the front end of the fixing frame two.

[0008] Furthermore, the fixing component includes a nut located on the inner circumference of the fixing frame, a screw threadedly connected to the inner wall of the nut, and a butterfly plate fixedly connected to the top end of the screw.

[0009] Furthermore, a limiting plate is fixedly connected to the top side of the outer wall of the screw, and the limiting plate is located at the top of the fixing frame.

[0010] Furthermore, a limiting ring is fixedly connected to the inner wall of the sleeve, and the limiting ring is disposed in a limiting groove opened on the tube body.

[0011] Furthermore, both the first and second limiting sleeves are fixedly connected to a limiting ring on their inner circumference, and the limiting ring is disposed in the second limiting groove opened on the pipe body.

[0012] Furthermore, the outer wall of the protective sleeve is coated with a tungsten carbide coating.

[0013] Furthermore, the limiting ring is made of rubber.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the limiting ring and the limiting groove cooperate with each other to restrict the movement between the pipe body and the pipe sleeve, thus initially ensuring the stability of the connection. The limiting ring and the limiting groove further play a positioning and stabilizing role in the connection between the pipe body and the pipe sleeve, enhancing the limiting relationship between them, thereby reinforcing the connection between the pipe bodies, effectively preventing the pipe connection from loosening during the pumping process, and ensuring the stability of the pipe connection.

[0016] 2. In this utility model, the butterfly spring installed on the outer wall of the pipe can absorb the impact force by elastic deformation when water flows. The protective sleeve on its outer periphery not only protects the butterfly spring, but the tungsten carbide coating on the outer wall also enhances the overall impact resistance and wear resistance. The synergistic effect of the two significantly improves the impact resistance of the pipe, reduces the risk of pipe damage caused by water flow impact, and ensures the continuous and stable operation of water pumping in water conservancy tunnels.

[0023] 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.

[0024] Reference Figures 1-3 An embodiment of this utility model is provided: a water pumping pipe for a water conservancy tunnel, including a pipe body 1, a butterfly spring 15 is provided on the outer wall of the pipe body 1, a protective sleeve 16 is fixedly connected to the outer periphery of the butterfly spring 15, the protective sleeve 16 is slidably connected to the outer wall of the pipe body 1, and limit groove 1 2 and limit groove 2 7 are provided at both ends of the outer wall of the pipe body 1. A pipe sleeve 4 is provided on the left side of the outer wall of the pipe body 1, and a fixing frame 1 9 and a fixing frame 2 10 are connected to the rear end of the pipe sleeve 4 through the limit sleeve 1 5 and the limit sleeve 2 8. The fixing frame 1 9 and the fixing frame 2 10 are connected by a nut 11, a screw 12 and a butterfly plate 13.

[0025] Specifically, when pumping begins, the butterfly spring 15 installed on the outer wall of pipe body 1 and the protective sleeve 16 fixedly connected to the outer periphery of the butterfly spring 15 come into play. The butterfly spring 15 has good elasticity and can absorb part of the impact force through its own elastic deformation when water flows into the pipe. The protective sleeve 16 is slidably connected to the outer wall of pipe body 1, which not only protects the butterfly spring 15 from external damage, but also the tungsten carbide coating on the outer wall of the protective sleeve 16 enhances the wear resistance and impact resistance of the protective sleeve 16. The two work together to improve the impact resistance of pipe body 1 and extend the service life of the pipe. The two pipe bodies 1 are inserted into the pipe sleeve 4 respectively, so that the limiting ring 3 fixedly connected to the inner wall of the pipe sleeve 4 is engaged into the limiting groove 2 opened on the outer wall of the two pipe bodies 1, completing the initial connection. At this time, the limiting ring 3 and the limiting groove 2 cooperate with each other to restrict the movement between pipe body 1 and pipe sleeve 4, thus initially ensuring the stability of the connection.

[0026] Reference Figures 2-4 The first limiting sleeve 5 is located at the rear end of the sleeve 4. The bottom end of the first limiting sleeve 5 is rotatably connected to the second limiting sleeve 8. The first limiting sleeve 5 is fixedly connected to the front end of the first fixing frame 9. The second limiting sleeve 8 is fixedly connected to the front end of the second fixing frame 10. The nut 11 is located on the inner circumference of the second fixing frame 10. The inner wall of the nut 11 is threaded with a screw 12. The top end of the screw 12 is fixedly connected to a butterfly plate 13. The top side of the outer wall of the screw 12 is fixedly connected to a limiting plate 14. The limiting plate 14 is set at the top end of the first fixing frame 9. The inner wall of the sleeve 4 is fixedly connected to a limiting ring 3. The limiting ring 3 is set in the limiting groove 2 opened on the tube body 1. The inner circumferences of the first limiting sleeve 5 and the second limiting sleeve 8 are both fixedly connected to a limiting ring 6. The limiting ring 6 is set in the limiting groove 7 opened on the tube body 1. The outer wall of the protective sleeve 16 is coated with a tungsten carbide coating. The limiting ring 3 is made of rubber.

[0027] Specifically, rotating the limiting sleeve 5 and limiting sleeve 8 at the rear end of the sleeve 4 causes the limiting ring 6, which is fixedly connected to the inner circumference of the limiting sleeve 5 and limiting sleeve 8, to engage in the limiting groove 7 opened on the outer wall of the tube body 1. The limiting ring 6 and limiting groove 7 further position and stabilize the connection between the tube body 1 and the sleeve 4, enhancing their restrictive relationship. Rotating the nut 11 adjusts the screw 12 to a perpendicular position to the fixing bracket 10, and then engages the screw 12 in the groove of the fixing bracket 9. At this time, the limiting plate 14 is located above the fixing bracket 9. Rotating the butterfly plate 13 causes the screw 12 to rotate. Since the screw 12 and the nut 11 are threadedly connected, Under the action of the thread of nut 11, screw 12 drives limit plate 14 to move downward, thereby reducing the distance between nut 11 and limit plate 14. During this process, fixing frame 1 9 and fixing frame 2 10 approach each other, exerting extrusion force on limit sleeve 1 5, limit sleeve 2 8 and limit ring 6, making the connection between pipe body 1 more stable and preventing loosening during water pumping. Limit ring 3 is made of rubber, which has good elasticity and flexibility, and can fit tightly against the surface of pipe body 1 and other connecting parts. It can effectively fill gaps, prevent water from leaking from the connection, ensure the sealing of the water pumping pipe, and avoid water waste and tunnel safety hazards caused by water leakage.

[0028] Working principle: When connecting pipes, first remove the pipe sleeve 4, insert the two pipe bodies 1 into the pipe sleeve 4, so that the limiting ring 3 on the pipe sleeve 4 is engaged with the limiting groove 2 of the two pipe bodies 1 for initial connection. Then rotate the limiting sleeve 5 and limiting sleeve 8 on the pipe sleeve 4, so that the limiting ring 6 on the limiting sleeve 5 and limiting sleeve 8 is engaged with the limiting groove 7 on the pipe body 1. Then rotate the nut 11 so that the screw 12 is perpendicular to the fixing bracket 10, and engage the screw 12 with the groove of the fixing bracket 9. At this time, the limiting plate 14 is located in the fixing bracket. Above the 9th pipe, the rotating butterfly plate 13 drives the screw 12 to rotate. Under the action of the thread of the nut 11, the limiting plate 14 moves downward, thereby reducing the distance between the nut 11 and the limiting plate 14. Thus, the limiting sleeve 2 and the limiting ring 6 are fixed by the fixing frame 2 10 and the fixing frame 19, thereby enhancing the stability of the connection between the pipe body 1 and the pipe body 1. After that, the connected pipe body 1 is installed in the tunnel. When water is pumped through the pipe body 1, the butterfly spring 15 and the protective sleeve 16 can improve the impact resistance of the pipe body 1.

[0029] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
