[0024] 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.

[0025] Reference Figures 1-6 This embodiment provides a circulating irrigation canal, including a canal body 1 having a filtration and storage section 11 and an irrigation canal section 12. A gate assembly 2 is provided on the canal body 1 for controlling the connection state between the filtration and storage section 11 and the irrigation canal section 12. A filter mechanism 3 for filtering rainwater and irrigation recycled water is detachably installed on the filtration and storage section 11. The gate assembly 2 includes a bracket 21 mounted on the canal body 1. A gate plate 23 that moves vertically is provided on the bracket 21 via a screw 22. A handle 24 is provided on the top of the screw 22. Several recycling pipes 4 are provided on the filtration and storage section 11. One end of the recycling pipe 4 passes through the canal body 1 and is located above the filter mechanism 3.

[0026] In this invention, the canal body 1 is set on farmland. During rainy days, rainwater is filtered by the filtration mechanism 3 and collected in the filtration and storage section 11 of the canal body 1. When irrigation is needed, the screw 22 is turned by the handle 24, causing the screw 22 to move the gate 23 on the support 21 upward. At this time, the filtration and storage section 11 is connected to the irrigation canal section 12, and the filtered and collected rainwater can be used for irrigation. The water after irrigation can be introduced into the filtration and storage section 11 through the recovery pipe 4, and then filtered again by the filtration mechanism 3. This allows for the collection of excess water and rainwater after irrigation, which can be reused for irrigation after appropriate treatment, thereby greatly improving the efficiency of water resource utilization.

[0027] Specifically, such as Figures 2-4 As shown, there are at least two filter mechanisms 3 arranged sequentially along the length of the filter water storage section 11. The filter mechanism 3 includes a filter screen 32 mounted on the filter water storage section 11 via a fixed frame 31. A connecting shaft 33 is mounted on the fixed frame 31, and a slot 111 that mates with the connecting shaft 33 is provided on the filter water storage section 11. The connecting shaft 33 is movably connected to the fixed frame 31 via a mounting groove 311 provided on the fixed frame 31. A return spring 312 that abuts against the connecting shaft 33 is provided in the mounting groove 311. A through-hole 313 that communicates with the mounting groove 311 is provided on the fixed frame 31, and a connecting plate 314 that passes through the through-hole 313 is provided on the connecting shaft 33.

[0028] The filter screen 32 in the fixed frame 31 is used for filtering rainwater and irrigation water. The filter mechanism 3 is laid along the length of the filter storage section 11 to ensure that the filter screen 32 filters rainwater and irrigation water. The fixed frame 31 can slide along the groove 111 on the filter storage section 11 via the connecting shaft 33, which facilitates the adjustment of the position of the filter mechanism 3. When it is necessary to add or remove the filter mechanism 3 for cleaning, the connecting plate 314 is used to pull the connecting shaft 33 to compress and reset the connecting shaft 33. Spring 312 retracts into mounting groove 311. At this time, connecting shaft 33 disengages from groove 111, and fixed frame 31 can be disassembled from filter water storage section 11 via filter screen 32 for easy maintenance and replacement. Connecting shaft 33 is located at both ends of fixed frame 31. Alternatively, connecting shaft 33 at one end of fixed frame 31 can be disengaged from groove 111. At this time, fixed frame 31 and filter screen 32 can be flipped and moved on filter water storage section 11, thereby enabling cleaning of filter water storage section 11 without disassembling filter mechanism 3.

[0029] Specifically, such as Figure 2 , Figure 3 and Figure 5 As shown, the filter mechanism 3 also includes a cleaning component 34 disposed on the fixed frame 31 for cleaning impurities filtered down from the filter screen 32. The cleaning component 34 includes a cleaning brush 342 that contacts the filter screen 32 via a mounting plate 341. The mounting plate 341 has connecting ends 343 at both ends, and the fixed frame 31 has a sliding groove 315 that mates with the connecting ends 343. The top of the mounting plate 341 has a handle 344.

[0030] The mounting plate 341 can slide along the groove 315 on the fixed frame 31 via the connecting end 343. After the filter screen 32 in the fixed frame 31 filters rainwater and irrigation water, the filtered impurities accumulate on the filter screen 32. At this time, the impurities are relatively dispersed on the filter screen 32. The operator can use the handle 344 to pull the mounting plate 341 along the groove 315 of the fixed frame 31. The cleaning brush 342 at the bottom of the mounting plate 341 sweeps the impurities on the filter screen 32 to a certain place as the mounting plate 341 moves. Then, the accumulated impurities can be cleaned, which facilitates the cleaning of the filter screen 32 and ensures that the filter screen 32 can effectively filter rainwater and irrigation water.

[0031] 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.
