Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a water conservancy irrigation pipeline. Background Technology

[0002] In water conservancy projects, irrigation pipelines, as water supply pipelines, are mainly used to introduce water sources such as urban tap water, reservoir water storage, and groundwater from wells, and transport them to farmland for irrigation, which helps to improve irrigation efficiency.

[0003] Application No. 202222908970.4 discloses a water conservancy irrigation pipeline. By setting on the irrigation pipeline with switchable nozzles, each section of the pipeline can be sprayed and irrigated independently, which is more flexible and diverse in terms of the irrigation range compared with traditional water conservancy sprinkler irrigation pipelines.

[0004] The threaded connection between the sealing cap and the threaded pipe in the above application is relatively unstable and prone to loosening. At the same time, the water outlet is easily blocked by impurities in the water. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a water conservancy irrigation pipeline, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water conservancy irrigation pipe, comprising a water conservancy pipe, a guide pipe connected to the top of the water conservancy pipe, a plurality of first drainage holes opened at the top of the guide pipe, a sealing cap rotatably connected to the outer wall of the guide pipe, a plurality of second drainage holes opened at the top of the sealing cap, a worm gear installed on the outer wall of the sealing cap, a protective cover installed at the top of the water conservancy pipe and outside the sealing cap, a worm gear rotatably connected inside the protective cover, the worm gear meshing with the worm gear, a handwheel rotatably connected to one side of the protective cover, the handwheel being connected to the worm gear, a telescopic spring installed inside the guide pipe and between the plurality of first drainage holes, a support plate connected to one end of the telescopic spring, a plurality of unblocking rods connected to the top of the support plate and outside the telescopic spring, the plurality of unblocking rods being respectively located at the bottom of the plurality of first drainage holes.

[0007] Preferably, flanges are installed at both ends of the water conservancy pipeline.

[0008] Preferably, a sealing gasket is installed on the top of the guide pipe, and a guide hole is provided inside the sealing gasket and on top of the plurality of first drain holes.

[0009] Preferably, the sealing cap has a groove inside, and a guide rail is slidably connected inside the groove, the guide rail being connected to the guide pipe.

[0010] Preferably, the number and inner diameter of the plurality of second drain holes and the plurality of first drain holes are the same.

[0011] Preferably, the diameters of the support plate and the plurality of unblocking rods are smaller than the inner diameters of the guide pipe and the plurality of first drainage holes, respectively.

[0012] This utility model provides a water conservancy irrigation pipe, which has the following beneficial effects:

[0013] 1. This irrigation pipeline has multiple first and second drainage holes respectively opened on the guide pipe and the sealing cap. Under the action of the worm gear and worm, the sealing cap can be driven to rotate and be fixed, so that the multiple second drainage holes are aligned or misaligned with the first drainage holes. This facilitates the control of the opening and closing of the first drainage holes. While performing sprinkler irrigation, it helps to make the sealing cap more stable. In addition, a support plate is connected to the guide pipe by a spring. The support plate rises and falls with the flow of water, which facilitates the driving of multiple unblocking rods to unblock the first and second drainage holes, which helps to prevent the drainage holes from becoming blocked.

[0014] 2. The irrigation pipe has a sealing gasket between the sealing cap and the guide pipe, which helps to increase the sealing between the guide pipe and the sealing cap and prevent leakage. The inner diameters of the first and second drainage holes are the same, and the diameter of the dredging rod is smaller than the inner diameter of the drainage hole, which helps to prevent the dredging rod from obstructing the flow of water.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a water conservancy irrigation pipe, including a water conservancy pipe 1, a guide pipe 2 connected to the top of the water conservancy pipe 1, a plurality of first drainage holes 3 opened at the top of the guide pipe 2, a sealing cap 4 rotatably connected to the outer wall of the guide pipe 2, a plurality of second drainage holes 5 opened at the top of the sealing cap 4, a sliding groove 18 opened inside the sealing cap 4, a guide rail 19 slidably connected inside the sliding groove 18, the guide rail 19 connected to the guide pipe 2, supporting the sealing cap 4 while allowing the sealing cap 4 to rotate, the number and inner diameter of the plurality of second drainage holes 5 and the plurality of first drainage holes 3 are all the same, so that... When multiple second drain holes 5 are misaligned with multiple first drain holes 3, the remaining parts of the sealing cap 4 can block the multiple first drain holes 3. When multiple second drain holes 5 are aligned with multiple first drain holes 3, the multiple first drain holes 3 are opened. A worm gear 6 is installed on the outer wall of the sealing cap 4. A protective cover 7 is installed on the top of the water pipe 1 and outside the sealing cap 4. A worm 8 is rotatably connected inside the protective cover 7. The worm 8 meshes with the worm gear 6. A handwheel 11 is rotatably connected to one side of the protective cover 7. The handwheel 11 is connected to the worm 8. Through the meshing of the worm 8 and the worm gear 6, the handwheel 11 drives the worm 8 and the worm gear 6. As the tube rotates, the sealing cap 4 rotates and is fixed, controlling the opening and closing of the first drain hole 3. A telescopic spring 12 is installed inside the guide pipe 2, located between the multiple first drain holes 3. One end of the telescopic spring 12 is connected to a support plate 13. Multiple unclogging rods 14 are connected to the top of the support plate 13, located outside the telescopic spring 12. The multiple unclogging rods 14 are located at the bottom of the multiple first drain holes 3. Through the deformation of the telescopic spring 12, the support plate 13 is automatically moved upwards by the impact of the water flow, causing the multiple unclogging rods 14 to pass through the multiple first drain holes 3 and the multiple second drain holes 5, and return to their original positions when the water flow stops. The guide pipe 2 is positioned away from multiple first drain holes 3 and multiple second drain holes 5 to facilitate unblocking and prevent clogging. A sealing gasket 16 is installed on the top of the guide pipe 2. The sealing gasket 16 has guide holes 17 inside and at the top of multiple first drain holes 3, which helps to increase the sealing between the sealing cap 4 and the guide pipe 2 and prevent leakage. The diameters of the support plate 13 and multiple unblocking rods 14 are smaller than the inner diameters of the guide pipe 2 and multiple first drain holes 3, which helps to prevent obstruction of water flow through the guide pipe 2 and multiple first drain holes 3. Flanges 15 are installed at both ends of the water pipe 1 for easy connection to the water outlet equipment.

[0022] In summary, when using this irrigation pipe, after connecting the water pipe 1 to the water pipe 1 via the flange 15, rotating the handwheel 11 drives the worm gear 8 inside the protective cover 7 to rotate. Under the action of the worm gear 8 and the worm wheel 6, the sealing cap 4 is rotated. The multiple second drainage holes 5 on the top of the sealing cap 4 are aligned with the multiple first drainage holes 3 on the top of the guide pipe 2, opening the multiple second drainage holes 5, so that the water flow in the water pipe 1 is guided to the guide pipe 2, and then sprayed outward from the multiple first drainage holes 3 and multiple second drainage holes 5 to irrigate the surrounding area. At the same time, the water flow pushes the support plate 13 inside the guide pipe 2 to move upward. Through the deformation of the telescopic spring 12 on the top of the support plate 13, the multiple unblocking rods 14 on the support plate 13 pass through the multiple first drainage holes 3 and multiple second drainage holes 5, and automatically reset when the water flow stops. The multiple unblocking rods 14 then leave the multiple first drainage holes 3 and multiple second drainage holes 5 to unblock the multiple first drainage holes 3 and multiple second drainage holes 5.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
