Description

Technical Field

[0001] This utility model relates to the field of farmland water conservancy pipeline technology, specifically to a farmland water conservancy anti-blockage pipeline. Background Technology

[0002] Pipe blockage is a common technical problem in farmland irrigation systems, especially at the connection between branch pipes and main pipes, where the accumulation of silt, weeds, and other impurities can obstruct water flow. Traditional anti-blockage solutions often use fixed filters, but these suffer from inconvenient cleaning and reduced filtration efficiency as the blockage worsens. Some designs with movable filters have drawbacks such as poor sealing or complex operation, and are inconvenient for operation without shutting down the system. Therefore, there is an urgent need for an anti-blockage pipe structure that can be quickly cleaned without shutting down the system, provides dual filtration, and has a good seal. Utility Model Content

[0003] To solve the above problems, this utility model provides a farmland irrigation anti-blockage pipeline.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a farmland water conservancy anti-blockage pipe, including a pipe connector, the pipe connector including a connecting pipe and several branch pipes, the branch pipes being connected to the lower part of the connecting pipe, a filter assembly being detachably connected inside the connecting pipe, and a sealing cap being detachably connected to the upper end of the connecting pipe. The filtration assembly includes a cylindrical filter cage with a water inlet on its side. The water inlet is positioned opposite to the branch pipe to be filtered. A filter screen is movably mounted at the connection between the branch pipe to be filtered and the connecting pipe. An operating lever is mounted on the top of the filter cage. When the filter cage is lifted out, the filter screen is rotated to filter the water flow from the branch pipe to be filtered.

[0005] As an optimization, a connecting plate is provided on the outer side of the middle part of the connecting pipe, and a sealing plate is slidably arranged inside the connecting plate. When the filter cage moves to the upper side of the connecting plate, it pushes the sealing plate into the interior of the connecting pipe to seal the connecting pipe.

[0006] As an optimization, the connecting plate has a connecting cavity inside, which communicates with the inside of the connecting pipe. The sealing plate is disposed inside the connecting cavity, and the end of the sealing plate is arc-shaped. When the sealing plate is inserted into the inside of the connecting pipe, the end of the sealing plate fits and seals against the inner wall of the connecting pipe. The sealing plate is equipped with an operating handle, and the upper part of the connecting plate is provided with an adjustment groove, and the operating plate is disposed inside the adjustment groove.

[0007] As an optimization, a guide arc is provided on the opposite side of the connecting pipe and the branch pipe to be filtered, and the filter screen is movably disposed inside the guide arc; A first positioning magnetic block is provided at one end of the guide arc away from the branch pipe to be filtered, and a second positioning magnetic block is provided at the other end of the guide arc. The filter screen is magnetically positioned by the first and second positioning magnetic blocks. In use, the filter screen is magnetically attracted by a strong magnet outside the connecting pipe and moves along the outer wall of the connecting pipe, pulling the filter screen to the inside of the branch pipe to be filtered.

[0008] As an optimization, the sealing cap is threadedly sealed to the upper end of the connecting pipe, and the operating rod is slidably sealed to the sealing cap.

[0009] The beneficial effects of this plan are as follows: The detachable filter cage and sealing cap design allows for easy removal and cleaning without disassembling the pipes. Through the synergistic effect of the main filter and the movable filter screen, the impurity interception rate is significantly improved. The filter screen can be directionally moved to the branch pipe to be filtered, enabling non-stop filtration of the pipe connection. When disassembling the filter cage, the connecting pipe is sealed with a sealing plate to prevent water leakage. The modular design adapts to different pipe diameters, making it especially suitable for agricultural irrigation scenarios with multiple branch pipe connections, effectively extending the service life of the pipes.

Detailed Implementation

[0019] like Figure 1 As shown, a farmland irrigation anti-clogging pipeline includes a pipeline connector, which includes a connecting pipe 1 and several branch pipes. The branch pipes are connected to the lower part of the connecting pipe 1. A filter assembly is detachably connected inside the connecting pipe 1, and a sealing cap 2 is detachably connected to the upper end of the connecting pipe 1. The filter assembly includes a cylindrical filter cage 3, with a water inlet 4 on the side of the filter cage 3. The water inlet 4 is positioned opposite to the branch pipe 5 to be filtered. A filter screen 6 is movably disposed at the connection between the branch pipe 5 to be filtered and the connecting pipe 1. An operating rod 7 is disposed on the top of the filter cage 3. When the filter cage 3 is removed upwards, the filter screen 6 is rotated to filter the water flow from the branch pipe 5 to be filtered.

[0020] The outer side of the filter cage 3 is adjacent to the inner wall of the connecting pipe 1. Turbid water is introduced into the connecting pipe 1 through the branch pipe 5 to be filtered, filtered by the filter cage 3, and then discharged through other branch pipes.

[0021] The filter cage 3 performs preliminary filtration of the water. When the filter cage 3 needs to be disassembled and cleaned, rotate the filter screen 6 to the outside of the water inlet 4, and then lift the filter cage 3 upwards.

[0022] The bottom of the filter cage 3 is a sealing structure, and the sides are a mesh structure.

[0023] like Figure 4 and Figure 6 As shown, a connecting plate 8 is disposed on the outer side of the middle part of the connecting pipe 1, and a sealing plate 9 is slidably disposed inside the connecting plate 8. When the filter cage 3 moves to the upper side of the connecting plate 8, it pushes the sealing plate 9 into the interior of the connecting pipe 1 to seal the connecting pipe 1.

[0024] The sealing plate 9 and the connecting plate 8 are fitted together in a sealed manner, and the width of the sealing plate 9 is equal to the inner diameter of the connecting pipe 1. Pull the operating rod 7 upward so that the filter cage 3 is higher than the connecting plate 8, and push the sealing plate 9 to seal the connecting pipe 1 without affecting the flow of the connecting pipe 1 and the branch pipe.

[0025] like Figure 4 and Figure 6As shown, the connecting plate 8 has a connecting cavity inside, which communicates with the inside of the connecting pipe 1. The sealing plate 9 is disposed inside the connecting cavity, and the end of the sealing plate 9 is arc-shaped. When the sealing plate 9 is inserted into the inside of the connecting pipe 1, the end of the sealing plate 9 fits and seals against the inner wall of the connecting pipe 1. The sealing plate 9 is equipped with an operating handle 10, and the upper part of the connecting plate 8 is provided with an adjustment groove, and the operating plate is located inside the adjustment groove.

[0026] like Figure 2 and Figure 5 As shown, a guide arc 11 is provided on the opposite side of the connecting pipe 1 and the branch pipe to be filtered 5, and the filter screen 6 is movably disposed inside the guide arc 11. The guide arc 11 is provided with a first positioning magnetic block 12 at one end away from the branch pipe 5 to be filtered, and a second positioning magnetic block 13 is provided at the other end of the guide arc 11. The filter screen 6 is magnetically positioned by the first positioning magnetic block 12 and the second positioning magnetic block 13. In use, the filter screen 6 is magnetically attracted by a strong magnet outside the connecting pipe 1 and moves along the outer wall of the connecting pipe 1, pulling the filter screen 6 to the inner side of the branch pipe 5 to be filtered.

[0027] A connecting magnetic block is disposed on the upper side of the filter screen 6, which can be magnetically attracted to either the first positioning magnetic block 12 or the second positioning magnetic block 13. A strong magnet is used to magnetically attract the connecting magnetic block from the outside of the connecting tube 1, and moving the strong magnet will cause the filter screen 6 to move inside the guide arc 11.

[0028] like Figure 2 As shown, the sealing cap 2 is threadedly sealed to the upper end of the connecting pipe 1, and the operating rod 7 is slidably sealed to the sealing cap 2.

[0029] In practical use, the connecting pipe 1 is connected to the branch pipe 5 to be filtered and other branch pipes according to the needs of the farmland irrigation system to ensure airtightness. The filter cage 3 is placed inside the connecting pipe 1, the inlet 4 is aligned with the branch pipe 5 to be filtered, the sealing cover 2 is threadedly fastened to the connecting pipe 1, and the operating rod 7 passes through the sealing cover 2 and maintains a sliding seal. Water enters from the branch pipe 5 to be filtered, and after passing through the main filter cage 3, impurities are intercepted, and clean water is output through other branch pipes. At this time, the filter screen 6 is fixed to the non-working end of the guide arc 11 by the second positioning magnet 13 to avoid interfering with the main filtration. When the filter cage 3 needs to be cleaned, an external strong magnet is used to attract the connecting magnetic block of the filter screen 6, and it moves along the outer wall of the connecting pipe 1 to the inner side of the branch pipe 5 to be filtered, and is fixed by the first positioning magnetic block 12. The water first passes through the movable filter screen 6 to ensure that impurities do not flow into the branch pipe; When the filter cage 3 is raised above the connecting plate 8, its bottom pushes the arc end of the sealing plate 9 into the inner wall of the connecting pipe 1, forming a seal to block the water flow. Rotate the sealing cover 2 to release the threaded lock, and pull the operating rod 7 upward to move the filter cage 3 upward; After removing the filter cage 3, rinse or replace the filter screen. After cleaning, reinsert the connecting pipe 1, tighten the sealing cap 2, pull out the sealing plate 9, and press down the operating rod 7 to reset the filter cage 3.

[0030] The entire operation can be carried out without interrupting the irrigation system. The synergistic design of the sealing plate 9 and the filter can effectively prevent impurities from flowing back, making it suitable for farmland water conservancy scenarios with high sediment content.
