Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural technology, and in particular to a multi-stage irrigation canal device for farmland. Background Art
[0002] Multi-stage irrigation canal systems for farmland are designed to ensure the efficient and stable operation of farmland irrigation systems. This system effectively delivers water to farmland through the layout and water diversion function of the multi-stage canals, meeting the irrigation needs of crops. The principle is that after the water source enters the canals, the water flows sequentially along the multi-stage canals until it reaches the farmland. During this process, control facilities adjust the flow rate and velocity of the water according to the irrigation needs of the farmland to ensure optimal irrigation results.
[0003] In the process of using multi-stage irrigation canals, the filtration structure on the canals can keep the canals unobstructed and reduce the phenomenon of water flow obstruction caused by impurities. Since there are solid particulate impurities in the water in the canals, with the long-term use of the filtration structure, these impurities are easily intercepted when flowing through the filter screen, thus clogging the filter screen. The clogging of the filter screen will lead to water flow obstruction and reduce irrigation efficiency. Utility Model Content

The filter screen is provided with a cleaning component for cleaning its surface.
[0007] As a further description of the above technical solution: the cleaning component includes a connecting rod that penetrates the fixed plate, and a brush that abuts against the surface of the filter screen is provided at the bottom of the connecting rod via a mounting bracket. A return spring is sleeved on the connecting rod.
[0008] As a further description of the above technical solution: the mounting bracket is provided with a positioning end that penetrates the brush, and a locking nut that abuts against the brush is provided on the positioning end.

[0025] 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.
[0026] Reference Figures 1-8 This embodiment provides a multi-stage irrigation canal device for farmland, comprising several canals 1. Adjacent canals 1 are connected by an integrally formed connecting section 2. A gate assembly 3 is provided on the canal 1 near the connecting section 2. The gate assembly 3 includes a gate plate 33 mounted on the canal 1 via a bracket 31. A lifting screw 32 for adjusting the raising and lowering of the gate plate 33 is provided on the bracket 31. A detachable filter mechanism 4 for preventing clogging is provided on the canal 1 downstream of the gate assembly 3. The filter mechanism 4 includes a filter screen 41 installed in a plug-in manner on the canal 1, and a positioning component 42 for positioning and fixing the filter screen 41 on the canal 1. A cleaning component 43 for cleaning the surface of the filter screen 41 is provided on the filter screen 41.
[0027] In this invention, several channel bodies 1 are arranged in a stepped manner through connecting sections 2, thus forming a multi-level water channel structure. The stepped water channel layout can make full use of the terrain's height difference, allowing water to flow naturally along the channel without requiring excessive power support. Each channel body 1 is equipped with a gate assembly 3. The rotation of the lifting screw 32 on the support 31 drives the movement of the gate plate 33, which can flexibly adjust and control the flow rate and velocity of the water to meet the irrigation needs of farmland. The water flowing through the gate assembly 3 is filtered through a filter screen 41, thereby preventing large impurities such as branches and stones from flowing into the next channel along with the connecting section 2. The first-stage channel body 1 reduces water flow obstruction caused by impurities. When the filter screen 41 is filtering, the cleaning component 43 can clean the surface of the filter screen 41, effectively removing impurities and dirt attached to the filter screen 41, keeping the filter screen 41 unobstructed, and enabling the filter screen 41 to maintain high-efficiency filtration performance. This ensures that the water channel is unobstructed, thereby improving irrigation efficiency and reducing water waste during irrigation. The filter screen 41 can be easily disassembled through the positioning component 42, allowing maintenance personnel to quickly replace or clean the filter screen 41, thereby shortening maintenance time and improving the overall system operating efficiency.
[0028] Specifically, such as Figures 2-6 As shown, the cleaning component 43 includes a connecting rod 432 that penetrates the fixing plate 431. The bottom of the connecting rod 432 is provided with a brush 434 that abuts against the surface of the filter screen 41 via a mounting bracket 433. A return spring 435 is sleeved on the connecting rod 432. A positioning end 4331 that penetrates the brush 434 is provided on the mounting bracket 433, and a locking nut 4332 that abuts against the brush 434 is provided on the positioning end 4331.
[0029] During the cleaning of filter screen 41, the operator presses the connecting rod 432 on the fixing plate 431, causing the connecting rod 432 to compress the return spring 435 and move the brush 434 on the mounting bracket 433. Then, the connecting rod 432 is released, and the brush 434 on the mounting bracket 433 returns to its original position under the action of the return spring 435. This process is repeated, causing the brush 434 to move repeatedly on the surface of filter screen 41. The moving brush 434 cleans the surface of filter screen 41, effectively removing impurities and dirt attached to filter screen 41 and keeping filter screen 41 unobstructed. When it is necessary to replace and clean the brush 434, the locking nut 4332 on the positioning end 4331 is unscrewed, and then the brush 434 can be pulled out from the positioning end 4331 to disassemble the brush 434 for easy replacement and cleaning.
[0030] Specifically, such as Figure 3 , Figure 4 and Figure 7As shown, the positioning component 42 includes a positioning screw 422 mounted on the channel body 1 via a fixing seat 421. One end of the positioning screw 422 is provided with a handle 423. The filter screen 41 is provided with a positioning hole 412 that cooperates with the positioning screw 422 via a positioning block 411. The bottom of the filter screen 41 is provided with a hook 413.
[0031] When the filter screen 41 needs to be disassembled for maintenance or cleaning, the positioning screw 422 on the fixing seat 421 is turned by the handle 423 to disengage it from the positioning hole 412 on the positioning block 411. Then, the filter screen 41 can be pulled out from the channel body 1 by the handle on the filter screen 41. The channel body 1 has a slot that matches the filter screen 41, so that the filter screen 41 can be installed and removed by sliding and plugging. The bottom of the filter screen 41 has a hook 413. When the filter screen 41 is pulled out from the channel body 1, large stones, branches and grass leaves and other impurities that have been filtered out can be picked out, thus cleaning the channel.
[0032] 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.
