[0036] (Example 1)

[0037] See Figure 1 , Figure 2 and Figure 4This utility model provides a water diversion device for irrigation, including a housing 1. Multiple fixing boxes 8 are symmetrically fixed to the bottom of the housing 1, providing a mounting foundation for the bottom support components of the entire device and ensuring the stability of the bottom structure. A docking assembly is provided on the outside of the housing 1, enabling a quick and sealed connection between the housing 1 and the connecting pipe 21, facilitating the assembly and use of the water diversion device with other transmission pipes.

[0038] Specifically, the fixed box 8 has notches extending along its width at both ends, and a fixed post 10 is rotatably mounted within the notches. The fixed post 10 is an important component of the entire support structure. Specifically, a rotating post 9 is fixed to one side of the fixed post 10 near the end face of the fixed box 8. The rotating post 9 is rotatably connected to the inside of the fixed box 8 and can rotate flexibly within the fixed box 8. This allows the fixed post 10 connected to it to rotate and unfold relative to the fixed box 8 and fold and store under the shell 1, providing a basis for the portability of the device.

[0039] A bottom plate 11 is rotatably connected to the bottom of the fixed column 10. An inclined brace 12 is rotatably connected inside the bottom plate 11. One end of the inclined brace 12 rotates relative to the bottom plate 11, so that the inclined brace 12 can support the bottom plate 11 during the support process. The other end of the inclined brace 12 is fixedly connected to a sliding column 13. The sliding column 13 can slide in the L-shaped groove of the fixed column 10 as the inclined brace 12 rotates, which plays the role of positioning and limiting the position of the inclined brace 12, and ensuring the stability of the support structure.

[0040] Furthermore, the fixed box 8 is equipped with two control components inside. The control components can control the position of the corresponding fixed column 10, thereby facilitating the unfolding and folding of the support structure to meet the needs of different usage scenarios.

[0041] Specifically, such as Figure 4As shown, the control assembly includes a square post 14 slidably disposed inside the fixed box 8. The fixed post 14 has a square sliding through hole, and the fixed box 8 has a square sliding groove aligned with the sliding through hole. The square post 14 can pass between the sliding through hole and the sliding groove. The side wall of the fixed box 8 has a sliding groove. The support arm of the pull rod 17, which is disposed outside the fixed box 8, passes through the sliding groove and is fixedly connected to the square post 14. The pull rod 17 can drive the square post 14 to move relative to the fixed box 8. Driven by the pull rod 17, the square post 14 can enter the sliding through hole of the fixed post 10 through the sliding groove of the fixed box 8 to restrict the rotation of the fixed post 10 relative to the fixed box 8, thereby locking the fixed post 10. The pull rod 17 can also drive the square post 14 to slide out of the sliding through hole of the fixed box 8 and into the sliding groove of the fixed box 8, thereby releasing the restriction on the fixed post 10. At this time, the fixed post 10 can rotate relative to the fixed box 8, so that the fixed post can be folded and stored under the shell 1 or unfolded from under the shell 1 to support the shell.

[0042] A telescopic column 15 is fixedly connected to one end of the square column 14 away from the rotating column 9. The other end of the telescopic column 15 is fixed inside the fixing box 8. A spring 16 is sleeved on the outside of the telescopic column 15. The telescopic column 15 plays a buffering and resetting role between the square columns 14. With the help of the spring 16, it can automatically push the square column 14 back to the position of the locking column 10. After the control of the pull rod 17 is canceled, the square column 14 can be automatically pushed back into the fixing column 10 to fix the position of the fixing column 10.

[0043] Filter screens 7 are slidably connected to both ends of the housing 1. The filter screens 7 can filter the water flowing into the housing 1, effectively blocking impurities in the water and preventing them from entering the subsequent watering operation, thus ensuring the cleanliness of the water. A rotating cover 2 is rotatably connected to the top of the housing 1. The rotating cover 2 can rotate flexibly at the top of the housing 1, making it easy to open or close the housing 1 when needed, facilitating internal operation and maintenance.

[0044] Furthermore, the rotating cover 2 is equipped with a disassembly and assembly component, which enables the quick disassembly and installation of the filter screen 7, making cleaning and maintenance more convenient and efficient.

[0045] (Example 2)

[0046] See Figures 1 to 3 The assembly includes a limiting block 4, which slides within the rotating cover 2. Inside the rotating cover 2, a slot 24 is provided along the sliding path of the limiting block 4. After the rotating cover 2 is closed, the hanging ring at the upper end of the filter screen 7 inserts into the slot 24, and the end of the limiting block 4 inserts into the hanging ring, locking the filter screen 7. Thus, the locking and unlocking of the filter screen 7 is achieved through the cooperation of the limiting block 4 and the filter screen 7, ensuring the stability of the filter screen 7 during operation and the ease of disassembly.

[0047] Preferably, a telescopic column 5 is fixedly connected to the rear end of the limiting block 4. A spring 6 is sleeved on the outside of the telescopic column 5. The end of the telescopic column 5 away from the limiting block 4 is fixedly connected to the inside of the rotating cover 2. One end of the spring 6 is fixedly connected to the rear end of the limiting block 4, and the other end of the spring 6 is fixedly connected to the inside of the rotating cover 2. The telescopic column 5 can retract when the limiting block 4 is subjected to external force, and together with the spring 6, it realizes the automatic reset and locking function of the limiting block 4. The spring 6 provides the elastic force for the limiting block 4 to reset, so that after the filter screen 7 is installed in place, it can automatically push the limiting block 4 into the hanging ring of the filter screen 7, lock the position of the filter screen 7, and ensure the stable operation of the filtration.

[0048] Furthermore, a through hole is provided on the top surface of the rotating cover 2. The support arm of the control rod 3 passes through the through hole and is fixedly connected to the limiting block 4. The control rod 3 allows the operator to manually pull the limiting block 4 so that the limiting block 4 slides out of the filter screen 7, thereby realizing the disassembly operation of the filter screen 7 and making cleaning and maintenance work easier.

[0049] (Example 3)

[0050] See Figure 1 , Figure 2 and Figure 5 The docking assembly includes a fixed cylinder 18, with a sealing gasket 20 fixedly connected inside. The fixed cylinder 18 is fixedly connected to the outside of the housing 1, providing a stable interface for the connection of the docking pipe 21, and the internal sealing gasket 20 ensures the sealing of the connection. A rotating ring 19 is threadedly connected to the outside of the fixed cylinder 18, and the rotating ring 19 is threadedly connected to the fixed cylinder 18, allowing the rotating ring 19 to rotate relative to the fixed cylinder 18, thereby locking and unlocking the docking pipe 21 for convenient and quick docking. The sealing gasket 20 can fit tightly against the outside of the docking pipe 21 when it is inserted into the fixed cylinder 18, effectively preventing water leakage and ensuring the sealing of the connection.

[0051] The external fixed connection of the connecting tube 21 has multiple sliding teeth 22, and the inside of the fixed cylinder 18 has limit grooves 23 at positions corresponding to the sliding teeth, which can restrict the movement of the connecting tube 21 after it is inserted. In addition, the rotating ring 19 can lock the connecting tube 21 to ensure a stable connection.

[0052] The working principle of this utility model is as follows: When the diversion device is installed, by pulling the pull rod 17, the square column 14 slides out from the inside of the fixed column 10, thus removing the restriction on the position of the fixed column 10. Then, by rotating the fixed column 10, when the fixed column 10 is rotated to the maximum unfolded position, the control of the pull rod 17 is released, and the spring 16 automatically pushes the square column 14 back into the inside of the fixed column 10, thereby fixing the position of the fixed column 10. Then, by pulling the bottom plate 11 to rotate inside the fixed column 10, the sliding column 13 slides inside the fixed column 10, and finally the sliding column 13 is stuck in the groove of the sliding groove on the outside of the fixed column 10, so that the diagonal brace 12 restricts the position of the bottom plate 11, and the bottom plate 11, diagonal brace 12, and fixed column 10 support the shell 1. The foldable storage of the support structure facilitates the transportation and storage of the diversion device, which is particularly suitable for temporary farmland or disaster relief emergency irrigation scenarios.

[0053] When the housing 1 needs to be connected with the connecting pipe 21, the sliding teeth 22 of the connecting pipe 21 are inserted into the interior of the fixed cylinder 18 until the connecting pipe 21 contacts the sealing gasket 20. Then, the rotating ring 19 is rotated so that the rotating ring 19 gradually moves closer to the end of the sliding teeth 22 away from the sealing gasket 20 until the rotating ring 19 rotates to the outermost connection position of the fixed cylinder 18. At this time, under the elastic action of the rotating ring 19, the inside of the rotating ring 19 will squeeze the outside of the sliding teeth 22, thereby making the connecting pipe 21 stuck inside the fixed cylinder 18, so as to complete the quick connection of the connecting pipe 21 and ensure the sealing effect.

[0054] When the housing 1 is in normal use, the filter screen 7 filters the water flow. When it is necessary to clean the inside of the housing 1 or remove the filter screen 7, pull the control lever 3 to make the limiting block 4 slide out from the inside of the filter screen 7, and then rotate the rotating cover 2 at the top of the housing 1 to make the housing 1 unfold as a whole, which is convenient for cleaning the housing 1 or removing the filter screen 7. When it is necessary to install the filter screen 7, slide the outside of the filter screen 7 into the inside of the side of the housing 1, and then rotate the rotating cover 2 to make the rotating cover 2 fit with the housing 1. At this time, the hanging ring of the filter screen 7 will automatically push the limiting block 4 to slide inside the rotating cover 2. When the top of the filter screen 7 is completely slid into the slot inside the rotating cover 2, the spring 6 will automatically push the limiting block 4 into the inside of the filter screen 7 to lock the position of the filter screen 7 and ensure the stability of the filtration operation.

[0055] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
