Description

Technical Field

[0001] This utility model relates to a water conservancy pipeline connection structure that facilitates dredging, and belongs to the field of pipeline dredging technology. Background Technology

[0002] During the use of water conservancy pipelines, silt, sand, garbage, and other debris tend to accumulate at the bottom of the pipes, reducing the effective cross-sectional area for water flow. If the silt is not removed in time, it will accumulate and eventually cause the pipeline to become completely blocked.

[0003] Traditional pipeline dredging typically requires large-scale excavation to locate pipeline joints or create a working surface. This process is time-consuming, labor-intensive, requires heavy machinery, and causes significant damage to ground facilities and the environment, resulting in cumbersome and costly dredging operations.

[0004] Furthermore, some existing pipelines have reserved maintenance ports or tees, but during long-term operation, silt and sediment can seep into and accumulate in these spare pipes, causing blockages and malfunctions. By the time dredging is needed, these reserved ports are already unusable. This results in problems with easily blocked and unreliable dredging channels.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This utility model addresses the shortcomings of the prior art by providing a water conservancy pipeline connection structure that facilitates dredging. It can solve the problems of cumbersome and costly dredging operations, as well as the problems of easy blockage and unreliability of dredging channels.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: A water conservancy pipeline connection structure for easy dredging includes a connecting cylinder, with transverse end pipes and nozzle inlet pipes connected to both sides of the connecting cylinder, and a longitudinal end pipe connected to the bottom of the connecting cylinder, with a sludge discharge pipe connected to the side of the longitudinal end pipe; both the nozzle inlet pipe and the sludge discharge pipe are 90-degree bends, and the top ends of both the nozzle inlet pipe and the sludge discharge pipe are connected to flange covers via flanges; both the nozzle inlet pipe and the sludge discharge pipe have flexible plungers installed inside, with the top ends of the flexible plungers fixed to the bottom of the flange covers.

[0008] Furthermore, the top ends of the nozzle inlet pipe and the sludge discharge pipe are set flush with each other.

[0009] Furthermore, the tops of both the nozzle inlet pipe and the sludge discharge pipe are located above the ground.

[0010] Furthermore, the centerline of the connecting cylinder is set in the horizontal direction.

[0011] Furthermore, the transverse end pipe is set perpendicular to the longitudinal end pipe.

[0012] Furthermore, the end of the transverse end pipe furthest from the connecting cylinder is connected to the inlet pipe via a flange, and the end of the longitudinal end pipe furthest from the connecting cylinder is sequentially connected to an on / off valve and an outlet pipe.

[0013] Furthermore, the longitudinal end pipe is connected to the on / off valve, and the on / off valve is connected to the delivery pipe via flanges.

[0014] Furthermore, a handle is fixedly installed on the top of the flange cover.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: By pre-installing dredging nozzles and sludge discharge pipes on the ground, excavation-free dredging is achieved. Operators can carry out all dredging operations directly on the ground without excavation, which greatly simplifies the process and reduces labor and equipment costs. The flexible plunger, integrated with the flange cover, can tightly seal the branch pipe during normal water transport, effectively preventing water and sediment from entering and ensuring the dredging channel is always available and reliable.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0017] Figure 1 This is an installation diagram of this utility model; Figure 2 This is a schematic diagram of the structure of this utility model; Figure 3 This is a schematic diagram showing the movement of silt in the usage state of this utility model.

Detailed Implementation

[0019] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2As shown in the figure, this utility model provides a water conservancy pipeline connection structure that facilitates dredging, including a connecting cylinder 1, with transverse end pipes 2 and nozzle inlet pipes 3 connected to both sides of the connecting cylinder 1, a longitudinal end pipe 4 connected to the bottom of the connecting cylinder 1, and a sludge discharge pipe 5 connected to the side of the longitudinal end pipe 4.

[0021] The centerline of the connecting cylinder 1 is set horizontally to connect pipes in various directions, and it is the confluence and turning point of water flow and silt.

[0022] The transverse end pipe 2 and the longitudinal end pipe 4 are arranged perpendicularly. The end of the transverse end pipe 2 away from the connecting cylinder 1 is connected to the conveying inlet pipe 6 through a flange. The end of the longitudinal end pipe 4 away from the connecting cylinder 1 is connected in sequence to the on / off valve 8 and the conveying outlet pipe 7. The longitudinal end pipe 4 is connected to the on / off valve 8, and the on / off valve 8 is connected to the conveying outlet pipe 7 through flanges.

[0023] Both the nozzle inlet pipe 3 and the sludge discharge pipe 5 are 90-degree bends, with their top ends flush and positioned above the ground. The nozzle inlet pipe 3 allows the sludge-clearing nozzle 13 to enter smoothly into the conveying inlet pipe 6. The sludge discharge pipe 5 is used for outputting sludge during the sludge-clearing process. Positioning the top ends of the nozzle inlet pipe 3 and the sludge discharge pipe 5 above the ground facilitates the sludge-clearing operation.

[0024] The top end of the nozzle inlet pipe 3 is connected to a first flange cover 9 via a flange, and the top end of the mud discharge pipe 5 is connected to a second flange cover 10 via a flange.

[0025] Flexible plungers 11 are installed inside both the nozzle inlet pipe 3 and the mud discharge pipe 5.

[0026] The top end of the flexible plunger 11 inside the nozzle inlet pipe 3 is fixed to the bottom of the first flange cover 9, and the first flange cover 9 can drive the flexible plunger 11 to move.

[0027] The top end of the flexible plunger 11 inside the mud discharge pipe 5 is fixed to the bottom of the second flange cover 10, and the second flange cover 10 can drive the flexible plunger 11 to move.

[0028] The flexible plunger 11 can fit tightly against the inner wall of the pipe to form an effective seal, ensuring that the normally flowing water and silt will not enter the nozzle inlet pipe 3 and the sludge discharge pipe 5, thus avoiding the accumulation of silt inside and causing blockage or failure.

[0029] The top of the first flange cover 9 and the second flange cover 10 are both fixedly equipped with handles 12. The handles 12 facilitate the application of force and make it easy to pull out or install the flange cover along with the flexible plunger 11 inside.

[0030] The specific working principle of this utility model is as follows: Under normal water conveyance conditions (excluding dredging periods), the normal water flow path is: inlet pipe 6 → transverse end pipe 2 → connecting cylinder 1 → longitudinal end pipe 4 → on / off valve 8 → outlet pipe 7.

[0031] Dredging Operation Status: When siltation occurs in the pipeline and dredging is required, first close the on / off valve 8 to block the water flow to the delivery pipe 7. Remove the first flange cover 9, the second flange cover 10, and their internal flexible plunger 11 using handle 12; insert the dredging nozzle 13 (usually connected to a high-pressure water pipe) through the opening of the nozzle inlet pipe 3. The nozzle will smoothly enter the connecting cylinder 1 along the 90-degree bend and further extend into the delivery inlet pipe 6. The high-pressure water jet from the dredging nozzle 13 will impact the silt on the inner wall of the delivery inlet pipe 6, loosening it and turning it into a mud-water mixture, which will then be sprayed out from the sludge discharge pipe 5. The top of the sludge discharge pipe 5 can be connected to sludge collection equipment such as a mud pump. After dredging is completed, retract the dredging nozzle 13, and then reinstall the first flange cover 9, the second flange cover 10, and their flexible plunger 11 back into their respective pipelines, ensuring a seal; open the on / off valve 8, and the system returns to normal water supply.

The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
