Description

Technical Field

[0001] This utility model relates to the field of water conservancy technology, specifically to a farmland irrigation canal structure. Background Technology

[0002] Farmland irrigation canals are artificially constructed waterways that bring water into farmland for irrigation. They are part of the farmland water conservancy system and are designed to effectively utilize water resources and improve farmland productivity, especially in areas with relatively scarce water resources.

[0003] There are many types of existing farmland irrigation canals, such as the irrigation canal based on farmland irrigation engineering disclosed in patent publication number CN222412865U. However, during the process of diverting water from farmland, the farmland usually contains a lot of impurities. When the water is diverted to the canal, the impurities can easily clog the filter baffles and other structures along with the water flow, making it impossible for the water to flow normally. This will prevent the water from being properly introduced into the fields. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a farmland irrigation canal structure that can effectively solve the problem that impurities accompany the water flow and block the existing device, resulting in the inability of water to flow normally.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a structure for an agricultural irrigation canal, comprising:

[0007] Main body of the canal;

[0008] A filter assembly, the filter assembly including a filter plate fixedly installed on the inner wall of the main body of the water channel;

[0009] A drive assembly, the drive assembly including a plurality of fan blades disposed on one side of the filter plate;

[0010] The lifting and cleaning assembly includes two lifting blocks disposed between the filter plate and the fan blade. The lifting blocks are driven to lift and lower. A rotating groove is provided on the side of the lifting block near the filter plate. A scraper is rotatably installed on the inner wall of the rotating groove. A limit block is fixedly installed on the inner wall of the rotating groove and below the scraper. A guide plate is provided on one side of the scraper.

[0011] Preferably, a sliding groove is symmetrically provided on one side of the filter plate near the upper position, a spring is fixedly installed on the inner wall of the sliding groove, a top block is fixedly installed on one end of the spring, and a magnetic strip is fixedly installed on one side of the filter plate below the top block.

[0012] Preferably, a main shaft is rotatably mounted on the inner wall of the water channel body, the outer wall of the main shaft is fixedly connected to the fan blade, and both ends of the main shaft penetrate the water channel body and are fixedly mounted with transmission rods.

[0013] Preferably, two horizontal plates are symmetrically installed on the upper end of the water channel body, and a driven shaft is rotatably installed inside the horizontal plate. The driven shaft is connected to the transmission rod for belt drive. Two reciprocating screws are rotatably installed on the inner bottom end of the water channel body. The outer wall of the reciprocating screws is threadedly matched with the lifting block. The reciprocating screws and the driven shaft are driven by a bevel gear pair.

[0014] Preferably, a fixing block is fixedly installed on the side of the lifting block away from the filter plate, and the fixing blocks are fixedly connected to the guide plate.

[0015] Preferably, it also includes a collection and filtration assembly, which includes a connecting plate disposed on one side of the filter plate, a water filter box fixedly installed on one side of the connecting plate, filter cotton fixedly installed on the inner wall of the water filter box, and multiple water outlets linearly arrayed on one side of the water filter box.

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] 1. The water flow drives the fan blades, which in turn power the mechanical transmission system to achieve automatic lifting and lowering of the scraper for cleaning. During descent, the scraper's angle is adjusted by a trigger block to prevent impurity accumulation. Upon ascent, it is repositioned using magnetic strips, precisely scraping away debris from the filter plate surface. The curved design of the guide plate, combined with water level changes, directs impurities to the filter box for secondary filtration, forming a dynamic, closed-loop cleaning process. This design solves the problem of clogging in traditional filtration devices, ensuring continuous water flow and reducing the frequency of manual maintenance.

[0018] 2. By combining mechanical scraping with physical filtration, impurities are graded and treated through a detachable filter box. The linear array design of the filter cotton and water outlet not only intercepts fine particles but also evenly disperses the water flow, avoiding secondary clogging caused by excessive local pressure. The modular structure facilitates replacement and cleaning, adapting to long-term operation under different water quality conditions, thus improving system stability and environmental adaptability.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example: Refer to Figures 1 to 6 A farmland irrigation canal structure, comprising:

[0030] Main body of the canal 1;

[0031] Filter assembly 2, the filter assembly 2 includes a filter plate 201 fixedly installed on the inner wall of the water channel body 1;

[0032] Drive assembly 3 includes a plurality of fan blades 302 disposed on one side of filter plate 201;

[0033] The lifting and cleaning assembly 4 includes two lifting blocks 404 disposed between the filter plate 201 and the fan blade 302. The lifting blocks 404 are driven to lift and lower. A rotating groove is provided on the side of the lifting block 404 near the filter plate 201. A scraper 406 is rotatably installed on the inner wall of the rotating groove. The scraper 406 is damped and rotatably connected to the inner wall of the rotating groove. The scraper 406 is made of iron material and can be magnetically attracted to the magnetic strip 205. A limit block 409 is fixedly installed on the inner wall of the rotating groove and below the scraper 406. A guide plate 408 is provided on one side of the scraper 406.

[0034] Reference Figure 2 A symmetrical groove 202 is provided on one side of the filter plate 201 near the upper position. A spring 203 is fixedly installed on the inner wall of the groove 202. A top block 204 is fixedly installed on one end of the spring 203. A magnetic strip 205 is fixedly installed on one side of the filter plate 201 and below the top block 204. The top block 204 can contact the upper and lower end faces of the scraper 406. When the scraper 406 is driven to rise, it contacts the top block 204. The limit block 409 restricts the rotation of the scraper 406. The scraper 406 will squeeze the top block 204 and compress the spring 203 to slide on the inner wall of the groove 202. When the scraper 406 is driven to fall, it contacts the top block 204. The resistance of the top block 204 will cause the scraper 406 to rotate.

[0035] Reference Figure 3 A main shaft 301 is rotatably installed on the inner wall of the water channel body 1. The outer wall of the main shaft 301 is fixedly connected to the fan blade 302. Both ends of the main shaft 301 pass through the water channel body 1 and are fixedly installed with transmission rods 303. The fan blade 302 is in contact with the water flow in the water channel body 1, so that the water flow drives the fan blade 302 to rotate.

[0036] Reference Figures 4 to 5Two horizontal plates 401 are symmetrically installed on the upper end of the water channel body 1. A driven shaft 402 is rotatably installed inside the horizontal plate 401. The driven shaft 402 is connected to the transmission rod 303 by belt drive. Two reciprocating screws 403 are rotatably installed on the inner bottom end of the water channel body 1. The outer wall of the reciprocating screw 403 is threadedly matched with the lifting block 404. The reciprocating screw 403 and the driven shaft 402 are driven by a bevel gear pair 405. A fixing block 407 is fixedly installed on the side of the lifting block 404 away from the filter plate 201. The fixing blocks 407 are fixedly connected to the guide plate 408. The upper end face of the guide plate 408 is opened into an arc surface. The height of the arc surface near the filter plate 201 is greater than the height of the arc surface away from the filter plate 201. This can effectively allow the water flow of the water channel body 1 to flow from the lower arc surface to the higher arc surface, and then flow to the scraper 406 and the upper end face of the filter plate 201, so that the water flow pushes the impurities to move.

[0037] Reference Figure 6 It also includes a collection and filtration assembly 5, which includes a connecting plate 501 disposed on one side of the filter plate 201. A water filter box 502 is fixedly installed on one side of the connecting plate 501. Filter cotton 504 is fixedly installed on the inner wall of the water filter box 502. Multiple water outlets 503 are linearly arrayed on one side of the water filter box 502.

[0038] The working principle of this utility model is as follows:

[0039] The main body 1 of the water channel is installed at the location where water needs to be drawn in. Water is introduced into the main body 1 for circulation. During the circulation of water in the main body 1, the water flow impacts the fan blades 302, causing the fan blades 302 to drive the main shaft 301 and the transmission rod 303 to rotate. During the rotation of the transmission rod 303, the driven shaft 402 is driven to rotate through the belt and pulley. The wrap angle between the belt and the pulley is greater than 120°. Since the larger the wrap angle, the larger the contact area between the belt and the pulley, the greater the friction force that can be transmitted. Therefore, the reliability and load-bearing capacity of the transmission can be improved, and the occurrence of slippage can be reduced. The rotating driven shaft 402 drives the reciprocating screw 403 to rotate through the bevel gear pair 405. During the rotation of the reciprocating screw 403, the lifting block 404 is driven to rise and fall during the rotation. During the rise and fall of the lifting block 404, the scraper 406 is driven to rise and fall vertically along one side of the filter plate 201.

[0040] During the process of being driven to descend, the lower end face of the scraper 406 will contact the top block 204. The scraper 406, which is resisted by the top block 204, will rotate and rise in the rotating groove, so that there is a certain gap between the scraper 406 and the filter plate 201. This allows the scraper 406 to avoid pushing the filtered impurities on one side of the filter plate 201 towards the bottom of the water channel body 1 during the descent.

[0041] After the scraper 406 is driven down to the inner bottom of the water channel body 1, the scraper 406 will magnetically engage with the magnetic strip 205 and rotate back to a state perpendicular to the filter plate 201. The end face of the scraper 406 will contact the side of the filter plate 201. During the process of being driven up, the end face of the scraper 406 will push the filter impurities on one side of the filter plate 201 upward and push the impurities to the upper end of the filter plate 201, so as to avoid the accumulation of impurities on one side of the filter plate 201 and cause blockage, which would prevent the water flow from being normal.

[0042] During the process of the lifting block 404 being driven to rise and fall, the lifting block 404 will also drive the fixed block 407 and the guide plate 408 to rise and fall together. Therefore, when the scraper 406 pushes the impurities to the upper end of the filter plate 201, the guide plate 408 is also driven to move to the upper end of the filter plate 201. The upper end surface of the guide plate 408 is opened as an arc surface. During the process of water flowing on its upper end surface, the water level will increase. The increased water level will impact the impurities on the upper end surface of the scraper 406, push them into the upper surface of the connecting plate 501, and flow into the water filter box 502. The water is filtered by the filter cotton 504, and the filtered water is discharged through the outlet 503.

[0043] In addition, after prolonged use, lubricating oil is squeezed into the main shaft 301, driven shaft 402, reciprocating screw 403 and various transmission components inside the water channel body 1 for lubrication and maintenance to reduce wear and improve transmission efficiency.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
