Description

Technical Field

[0001] This utility model relates to the field of low-pressure irrigation pipe technology, specifically to a pipe anti-clogging and pressure-resistant structure. Background Technology

[0002] Low-pressure irrigation pipes are an important component of agricultural water-saving irrigation systems. They deliver water to crop roots at lower operating pressures, reducing energy consumption, equipment investment, and operating costs compared to high-pressure irrigation systems. They also prevent soil compaction and water loss caused by high pressure, thus improving irrigation efficiency. However, low-pressure irrigation pipes may experience blockages or deformation over long-term use. Therefore, it is necessary to add anti-blockage and pressure-resistant structures to the pipes to enhance their strength and effectively improve their anti-blockage and pressure-resistant properties.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] In common low-pressure irrigation pipes, irrigation water flows through the pipes, and impurities such as mud and sand in the irrigation water can easily accumulate in the pipes, causing blockages and affecting irrigation efficiency. Furthermore, when the pipes are subjected to external pressure for a long time or excessive pressure, they are prone to deformation or rupture, thus reducing the service life of the pipes. Utility Model Content

[0005] The purpose of this invention is to provide a pipe anti-clogging and pressure-resistant structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe anti-clogging and pressure-resistant structure, comprising an inner pipe, a spiral guide strip installed on the inner wall of the inner pipe, a pressure-resistant layer installed on the outside of the inner pipe, a reinforcing layer installed on the outside of the pressure-resistant layer, an outer pipe installed on the outside of the reinforcing layer, and a filter assembly installed on one side of the outer pipe.

[0007] The filter assembly includes a mounting bracket installed on one side of the outer tube. A first fixing block is installed around the outer perimeter of the mounting bracket. A filter screen frame is installed on one side of the mounting bracket. A second fixing block is installed around the outer perimeter of the filter screen frame. A limit ring is installed on one side of the filter screen frame.

[0008] More preferably, the inner side of the spiral guide bar is designed to be arc-shaped.

[0009] More preferably, the material of the pressure-resistant layer is glass fiber.

[0010] More preferably, the reinforcing layer is made of steel wire and is configured as a steel wire mesh.

[0011] More preferably, one side of the mounting bracket has a groove that matches the external dimensions of the limiting ring.

[0012] More preferably, the first fixing block has a first slot.

[0013] More preferably, the second fixing block has a second slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This low-pressure irrigation pipe uses a filter assembly to perform preliminary filtration of irrigation water, removing impurities such as sediment. This reduces the impurity content of the water entering the pipe, thus lowering the likelihood of blockage. Furthermore, a spiral guide strip guides the irrigation water into a spiral flow pattern, using centrifugal force to expel any remaining impurities, preventing them from adhering to the inner wall of the pipe and causing blockages, further reducing the possibility of clogging. Additionally, a fiberglass pressure-resistant layer and a steel wire reinforcement layer are added. The pressure-resistant layer effectively enhances the pipe's compressive strength, while the reinforcement layer increases its overall strength, further increasing its compressive strength and effectively preventing pipe deformation or breakage.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a pipe anti-clogging and pressure-resistant structure, including an inner pipe 1, a spiral guide strip 2 installed on the inner wall of the inner pipe 1, a pressure-resistant layer 3 installed on the outside of the inner pipe 1, a reinforcing layer 4 installed on the outside of the pressure-resistant layer 3, an outer pipe 5 installed on the outside of the reinforcing layer 4, and a filter assembly 6 installed on one side of the outside of the outer pipe 5.

[0023] The filter assembly 6 includes a mounting bracket 601 installed on one side of the outer tube 5. A first fixing block 602 is installed around the outer perimeter of the mounting bracket 601. A filter screen frame 603 is installed on one side of the mounting bracket 601. A second fixing block 604 is installed around the outer perimeter of the filter screen frame 603. A limit ring 605 is installed on one side of the filter screen frame 603.

[0024] In this embodiment, as Figure 1 and Figure 2 As shown, the inner side of the spiral guide bar 2 is designed as an arc.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the material of the pressure-resistant layer 3 is glass fiber.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the reinforcing layer 4 is made of steel wire and is designed as a steel wire mesh.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a groove with the same external dimensions and structure as the limiting ring 605 is provided on one side of the mounting bracket 601.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first fixing block 602 has a first slot.

[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the second fixing block 604 has a second slot.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the working process of this anti-clogging and pressure-resistant pipe structure during use is as follows:

[0031] First, the bolt is passed through the second slot of the second fixing block 604, and then through the first slot of the first fixing block 602. The bolt is then used for installation. At this point, the limiting ring 605 will enter the groove on one side of the mounting bracket 601, completing the installation of the filter frame 603. Filtration can then begin. The filtered water enters the pipe and is guided by the spiral guide strip 2 to form a spiral flow. Centrifugal force is used to expel any remaining impurities from the water, preventing them from adhering to the inner wall of the inner pipe 1 and causing blockages. This effectively increases the anti-blocking effect. Furthermore, the arc-shaped spiral guide strip 2 effectively reduces the eddy current area formed by water flow turbulence, further enhancing the anti-blocking effect. The fiberglass pressure-resistant layer 3 improves the pipe's pressure resistance, and the steel wire mesh reinforcement layer 4 effectively increases the pipe's strength, further improving its pressure resistance.
