Technical Field

[0001] The utility model relates to the technical field of irrigation water pipes, in particular to a high-strength polyethylene irrigation pipe. Background Art

[0002] Farmland water conservancy and irrigation projects are the basic infrastructure for agricultural production services. They can effectively control, utilize and transport water resources, improve the efficiency of water resource use, provide water resource allocation services for agricultural production development, and promote increased income and production from farmland planting.

[0003] Irrigation requires diverting water from natural sources far from farmland to nearby fields. This diversion or diversion typically involves irrigation pipes with diameters of 0.5-1 meter. Existing irrigation pipes are often exposed to the ground or ditches during use, making them susceptible to external impacts and collisions over extended periods of use. These impacts can damage the pipes, leading to leaks.

[0004] Therefore, the irrigation pipes in the prior art have technical problems of low strength and easy breakage. Utility Model Content

[0035] The specific embodiments shown below are intended to serve as descriptions of various configurations of the subject technology of the present invention and are not intended to represent the only configuration in which the subject technology of the present invention can be practiced. The specific embodiments include specific details intended to provide a thorough understanding of the subject technology of the present invention. However, it will be clear and apparent to those skilled in the art that the subject technology of the present invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0036] It will be understood that, herein, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another entity or operation, and are not intended to express or imply any actual relationship or order between these entities or operations.

[0037] The terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0038] Reference Figures 1 to 6 As shown, a high-strength polyethylene irrigation pipe comprises a core pipe 1 and a protective pipe 2 arranged outside the core pipe 1, and an intermediate pipe 3 is arranged between the protective pipe 2 and the core pipe 1;

[0039] An internal buffer assembly for positioning the intermediate tube 3 is provided between the core tube 1 and the intermediate tube 3;

[0040] An external buffer assembly is provided between the intermediate tube 3 and the protective tube 2. The external buffer assembly includes a reinforcing rib 21 provided inside the protective tube 2 and a rib plate 22 provided on the inner wall of the protective tube 2. The intermediate tube 3 is provided with a groove 31 that cooperates with the rib plate 22. A portion of the rib plate 22 extends into the groove 31, and the rib plate 22 does not contact the bottom wall of the groove 31.

[0041] Both ends of the core tube 1 are provided with splicing rings 11 for facilitating the splicing of two adjacent core tubes 1 , and the splicing rings 11 are provided with an annular groove 12 for placing a sealing ring.

[0042] Specifically, the protection tube 2 is located at the outermost side and usually directly bears collision or impact. Therefore, the protection tube 2 should have high strength.

[0043] To this end, in some embodiments, the reinforcing ribs 21 include longitudinal ribs arranged along the length direction of the protective tube 2 , and the reinforcing ribs 21 also include annular ribs, the annular ribs and the longitudinal ribs are an integrated structure, and the annular ribs are evenly arranged along the length direction of the protective tube 2 .

[0044] The annular ribs and longitudinal ribs work together to form a grid-like reinforcement rib 21. The reinforcement ribs 21 are pre-installed within the protective tube 2, forming an integral structure with the rest of the tube. The reinforcement ribs 21 provide the protective tube 2 with increased strength, making it less susceptible to damage from impacts or collisions. Furthermore, the reinforcement ribs 21 evenly distribute forces across the protective tube 2, further reducing its damage resistance.

[0045] Reference Figures 1 to 6As shown, in some embodiments, the annular ribs have a circular cross-section, while the longitudinal ribs have a polygonal cross-section. The annular ribs are used to disperse impacts or collisions on the protective tube 2. Therefore, the circular cross-section of the annular ribs allows for a certain degree of elastic deformation, preventing them from breaking when the protective tube 2 is impacted or collided.

[0046] The longitudinal reinforcement should have a higher flexural strength to prevent it from bending and deformation. The use of longitudinal reinforcement with a polygonal cross-section makes the longitudinal reinforcement have a higher flexural strength.

[0047] In some embodiments, a grid-shaped ridge 23 is provided on the outer wall of the protection tube 2 , and the grid-shaped ridge 23 and the protection tube 2 are an integrated structure.

[0048] The grid-like ridges 23 are used to increase the strength of the protection tube 2 so that the protection tube 2 is not easily damaged.

[0049] In some embodiments, the inner buffer assembly is fixed to the core tube 1 . The inner buffer assembly is a buffer tube 13 . There are multiple buffer tubes 13 . The multiple buffer tubes 13 are evenly arranged along the circumferential direction of the core tube 1 .

[0050] The buffer tube 13 can be made of a rubber tube or other similar material. The buffer tube 13 has a certain elastic deformation capacity. When the buffering capacity of the external buffer assembly is insufficient to completely offset the impact or collision of the protective tube 2, the buffer tube 13 can produce a certain elastic deformation to offset a portion of the force. This ensures that the core tube 1 does not bear the force when the protective tube 2 is impacted or struck, or bears a smaller force, thereby making the core tube 1 less susceptible to damage.

[0051] Reference Figures 1 to 6 As shown, in some embodiments, the intermediate tube 3 is provided with a positioning groove 32 for positioning the buffer tube 13, with a portion of the intermediate tube 3 located within the positioning groove 32. The positioning groove 32 cooperates with the buffer tube 13 to position the intermediate tube 3 circumferentially relative to the core tube 1. The number of positioning grooves 32 and buffer tubes 13 is not limited and can be reasonably determined as needed.

[0052] The buffer tube 13 is integrally formed with the core tube 1, and the positioning groove 32 is staggered with the groove body 31. When the buffer tube 13 is integrally formed with the core tube 1, the buffer tube 13 and the core tube 1 are made of the same material. The buffer tube 13 can have a circular cross-sectional shape. Because a circular cross-sectional buffer tube 13 is more susceptible to elastic deformation under applied force, a circular cross-sectional shape is preferably employed for the buffer tube 13.

[0053] At the same time, since the buffer tube 13 with a circular cross-section is easy to produce elastic deformation and is not easy to break after multiple deformations, the buffer tube 13 has a longer service life, and thus the irrigation pipe has a longer service life.

[0054] Reference Figures 1 to 6 As shown, in some embodiments, the outer wall of the intermediate tube 3 is provided with a plate 33 forming the groove 31 , and two plates 33 cooperate to form the groove 31 , and the groove 31 is evenly arranged along the circumferential direction of the intermediate tube 3 .

[0055] The plate body 33 and the intermediate tube 3 are an integrated structure, and the cross-section of the plate body 33 is a rectangle.

[0056] Plate 33 has two functions. One is to increase the strength of intermediate tube 3. Plate 33 functions similarly to a rib, effectively increasing the strength of intermediate tube 3 and making it less susceptible to damage. Another function of plate 33 is to form a groove 31, allowing a portion of rib 22 to enter groove 31, preventing rib 22 from intervening in groove 31.

[0057] Reference Figures 1 to 6 As shown, in some embodiments, the rib plate 22 and the protection tube 2 are an integrated structure, and the cross-section of the rib plate 22 is a rectangle.

[0058] The ribs 22 function similarly to the plate 33, serving two functions. One function is to increase the strength of the protective tube 2, making it less susceptible to damage. Another function is to coordinate with the groove 31 to position the protective tube 2 circumferentially relative to the intermediate tube 3.

[0059] Because the protective tube 2 is relatively strong, the protective tube 2 retains a certain strength when subjected to collisions or impacts, or the protective tube 2 itself undergoes a certain degree of elastic deformation when subjected to collisions or impacts. Therefore, the protective tube 2 provides excellent protection. The core tube 1 is not easily damaged during long-term use, thereby extending the service life of the irrigation tube.

[0060] In some embodiments, the splicing ring 11 is an integral structure with the core tube 1. Multiple ring grooves 12 can be provided to provide more sealing rings to prevent leakage at the splicing of two adjacent core tubes 1.

[0061] The above describes the technical solution and corresponding details of the subject matter of the present invention. It can be understood that the above description is only some implementation plans of the technical solution of the subject matter of the present invention, and some details may be omitted during its specific implementation.

[0062] In addition, in some embodiments of the above utility model, multiple embodiments may be implemented in combination. Due to space limitations, various combination schemes are not listed one by one. Those skilled in the art can freely combine and implement the above embodiments as needed in specific implementation to obtain a better application experience.

[0063] When implementing the technical solution of the present invention, those skilled in the art may obtain other detailed configurations or drawings based on the technical solution of the present invention and the drawings. Obviously, these details still fall within the scope covered by the technical solution of the present invention without departing from the technical solution of the present invention.
