Description

Technical Field

[0001] This utility model relates to the field of modular culvert technology, specifically a modular culvert for farmland irrigation. Background Technology

[0002] Currently, closed-loop water pipeline systems buried underground replace traditional open channel irrigation. The main materials are PVC / PE plastic pipes, precast concrete pipes, and ceramic pipes. They are generally suitable for arid and water-scarce areas, areas with high evaporation rates, and large-scale farms.

[0003] Currently, during the installation of culverts, situations arise where the length is insufficient or excessive. This usually occurs at bends, as culvert pipes are custom-made and cannot be cut, necessitating the excavation and re-laying of the culvert. Furthermore, pipes connected using an embedded splicing method cannot be removed from the middle, as the embedded portion obstructs the removal of the pipe. Utility Model Content

Through the middle outer pipe, sliding inner pipe, sealing ring frame and tapered pipe, the connection of the pipe can be extended and shortened, making installation more convenient. Moreover, the two sliding inner pipes inside the middle outer pipe can be moved inward to separate the pipe, making disassembly more convenient.

[0022] Underdrain Supervisor 1;

[0023] An extension pipe structure is installed inside the main culvert 1;

[0024] The extension pipe structure includes an outer central pipe 2, two sliding inner pipes 3, two sealing ring frames 4, and two conical pipes 5. The outer wall of one of the conical pipes 5 is slidably embedded in the main culvert 1. The two sliding inner pipes 3 are slidably embedded in each other at their close ends, and the two sliding inner pipes 3 are respectively connected to the two conical pipes 5 at their far ends. The inner walls of the two sealing ring frames 4 are slidably fitted onto the two sliding inner pipes 3, and the outer walls of the two sealing ring frames 4 are slidably embedded in the outer central pipe 2.

[0025] In this implementation plan: the main pipeline is laid through the underground culvert 1. The tapered pipe 5 and the sliding inner pipe 3 are connected together. The tapered pipe 5 can be embedded into the underground culvert 1, and the sliding inner pipe 3 can be embedded into the middle outer pipe 2. The two sliding inner pipes 3 can slide into the middle outer pipe 2, thereby changing the distance between the two tapered pipes 5. This distance can be changed according to the pipeline being laid, extending and shortening the connection of the pipeline, making installation more convenient. Moreover, the two sliding inner pipes 3 in the middle outer pipe 2 can be moved inward to separate the pipeline, making disassembly more convenient. Two sealing ring frames 4 are fitted on the two sliding inner pipes 3 and simultaneously embedded into the middle outer pipe 2. Using extrusion force, the sealing ring frames 4 are embedded between the sliding inner pipes 3 and the middle outer pipe 2 to form a fixed structure.

[0026] Specifically, the outer walls of the main culvert 1 are provided with first connecting discs 6 at both ends, and the outer walls of the first connecting discs 6 are provided with multiple connecting holes at equal intervals along the circumferential surface.

[0027] In this embodiment: the first connecting plate 6 on the main culvert 1 can correspond to the third connecting plate 8 at the connection between the tapered pipe 5 and the sliding inner pipe 3, and the tapered pipe 5 can be completely embedded into the main culvert 1 by using the connecting hole for installation and fixation.

[0028] Specifically, the outer wall of the middle outer tube 2 is provided with a second connecting plate 7 at both ends, and the outer wall of the second connecting plate 7 is provided with multiple connecting holes at equal intervals along the circumferential surface.

[0029] In this embodiment: the second connecting plate 7 on the middle outer tube 2 can correspond to the fourth connecting plate 9 on the sealing ring frame 4, and the connecting hole is used to connect and fix it, so that the sealing ring frame 4 can be embedded between the middle outer tube 2 and the sliding inner tube 3 to form a fixed shape.

[0030] Specifically, a third connecting plate 8 is provided on the outer wall of each conical tube 5 and sliding inner tube 3 at the connection point, and multiple connecting holes are provided at equal intervals along the circumferential surface of the outer wall of the third connecting plate 8.

[0034] Specifically, multiple rubber rings 10 are slidably embedded in the outer walls of the two conical tubes 5.

[0035] In this embodiment, multiple rubber rings 10 are used to increase the sealing performance of the tapered pipe 5 when it is embedded in the main culvert 1.

[0036] In use, the main culvert 1 is used for laying the main pipeline. The tapered pipe 5 and the sliding inner pipe 3 are connected together. The tapered pipe 5 can be embedded into the main culvert 1, and the sliding inner pipe 3 can be embedded into the middle outer pipe 2. The two sliding inner pipes 3 can slide into the middle outer pipe 2, thereby changing the distance between the two tapered pipes 5. This distance can be adjusted according to the pipeline being laid, extending or shortening the connection of the pipeline, making installation more convenient. Moreover, the two sliding inner pipes 3 inside the middle outer pipe 2 can be moved inward to separate the pipeline, making disassembly more convenient. Two sealing ring frames 4 are fitted inside the two sliding inner pipes. The sealing ring frame 4 is embedded in the middle outer pipe 2 on the pipe 3. Using the extrusion force, the sealing ring frame 4 is embedded between the sliding inner pipe 3 and the middle outer pipe 2 to form a fixed structure. The first connecting plate 6 on the main pipe 1 can correspond to the third connecting plate 8 at the connection between the tapered pipe 5 and the sliding inner pipe 3. It is installed and fixed using the connecting hole, so that the tapered pipe 5 is completely embedded in the main pipe 1. The second connecting plate 7 on the middle outer pipe 2 can correspond to the fourth connecting plate 9 on the sealing ring frame 4. It is connected and fixed using the connecting hole, so that the sealing ring frame 4 can be embedded between the middle outer pipe 2 and the sliding inner pipe 3 to form a fixed structure.
