Description

Technical Field

[0001] The present application relates to the technical field of farmland water conservancy engineering, and in particular to an irrigation and drainage system with a silt removal function. Background Art

[0002] There are many ways to irrigate farmland, such as drip irrigation, sprinkler irrigation, flood irrigation, etc. Flood irrigation is widely used because of its low cost and simplicity. The source of water for farmland irrigation is mainly surface water, including river runoff, lakes, and surface runoff intercepted by reservoirs, ponds, etc. By building canals, water is diverted to farmland for irrigation.

[0003] Since surface water is easily polluted, there is a lot of garbage in the irrigation water. If it is not treated, it is easy to cause the irrigation canal to be blocked, farmland to be polluted, and the normal growth of crops to be affected. At present, the common practice is to build a trash rack at the water inlet end of the canal to block the garbage and prevent it from entering the irrigation canal. Although this method can block garbage, the garbage will gather at the trash rack and needs to be cleaned frequently, otherwise it will easily cause clogging.

[0004] There are two main types of garbage in surface water. One is hard floating garbage such as plastic bottles and plastic foam. This type of garbage is relatively easy to clean and can be directly salvaged. The other type is soft floating garbage such as plastic bags and plastic packaging. When this type of garbage is blocked by the trash rack, it will be entangled with the trash rack under the action of water flow, which not only makes it easier to clog the trash rack, but also makes the cleaning process time-consuming and labor-intensive, making it difficult to meet usage needs. Summary of the invention

[0005] In order to solve or partially solve the problems existing in the related art, the present application provides a drainage and irrigation system with a silt removal function, in which garbage is intercepted by setting an arc-shaped trash-blocking bar, and a corresponding cleaning mechanism is set to automatically clean the garbage at the trash-blocking bar, thereby avoiding garbage accumulation and improving the convenience of the cleaning process.

[0040] In this embodiment, see Figure 1A drainage and irrigation system with a desilting function comprises a trash bar 1, a cleaning mechanism 2, and a recovery mechanism 3. The trash bar 1 is an arc-shaped structure, and the trash bar 1 is evenly and fixedly installed in the drainage and irrigation main channel 6. The water flow direction in the drainage and irrigation main channel 6 is from the inner side of the trash bar 1 to the outer side. When garbage passes through the trash bar 1 with the water flow, the water flow flows normally and the garbage is blocked; the cleaning mechanism 2 is installed on the inner side of the trash bar 1, and is used to clean up the garbage intercepted at the trash bar 1. The cleaning mechanism 2 comprises a bottom frame 21 , a rotating shaft 22, a cleaning plate 24, a base frame 21 is fixedly mounted on the drainage and irrigation main channel 6, and a rotating shaft 22 is rotatably mounted on the base frame 21, a rotating drum 23 is fixedly mounted on the rotating shaft 22, a plurality of cleaning plates 24 corresponding to the dirt-blocking rod 1 are evenly and fixedly mounted on the rotating drum 23 along its circumferential direction, and the number of the cleaning plates 24 is 6 to 10. When in use, the cleaning plates 24 are impacted by water flow, thereby driving them to rotate. The cleaning plates 24 will continuously clean the dirt-blocking rod 1 during the rotation process and bring the garbage into the recycling mechanism 3;

[0041] See also Figure 2 Furthermore, in order to improve the cleaning effect of the flexible floating garbage, a cleaning groove 26 corresponding to the dirt-blocking bar 1 is opened on the cleaning plate 24, and the dirt-blocking bar 1 is concentric with the rotating shaft 22. When the cleaning plate 24 rotates, the cleaning groove 26 fits with the dirt-blocking bar 1, increasing the contact area between the cleaning plate 24 and the dirt-blocking bar 1, thereby facilitating the scraping of the flexible garbage wrapped around the dirt-blocking bar 1 and ensuring the smooth flow of the dirt-blocking bar 1; the garbage swept by the cleaning mechanism 2 can be received by the recycling mechanism 3 and moved out of the drainage and irrigation main channel 6. Furthermore, side plates 25 are also provided on the left and right sides of the cleaning plate 24, and the side plates 25 can prevent the garbage from sliding back into the drainage and irrigation main channel 6 from the left and right sides of the cleaning plate 24.

[0042] See also Figure 6 , 7 The recovery mechanism 3 is installed on the outside of the dirt-blocking rod 1 and is used to receive the cleaning mechanism. The recovery mechanism 3 includes a recovery plate 31 and a scraper 33. The recovery plate 31 is an arched structure with a high middle and low two sides, and a scraper 33 is slidably connected to the left and right sides of the recovery plate respectively. The two scrapers 33 can reciprocate on the recovery plate 31, and the movement directions of the two scrapers 33 are always opposite. Collection boxes 4 for uniformly collecting garbage are also arranged at the left and right ends of the recovery plate 31. When the garbage slides from the cleaning plate 24 to the recovery plate 31 under the action of gravity, the garbage will slide from the recovery plate 31 into the collection box 4 under the action of the inclined surface. Furthermore, since the garbage is relatively moist, some of the garbage is easily adhered to the recovery plate 31. The adhering garbage can be scraped off by the back and forth movement of the scraper 33. In addition, the cleaning plate 24 will also bring up moisture during the rotation process. Some of the water will flow along the cleaning plate 24 to the recovery plate 31 and flow down along the recovery plate 31. This part of water can impact the garbage, making it easier to slide along the inclined surface into the collection box 4.

[0043] In this embodiment, in order to drive the scraper 33, the recovery mechanism 3 further includes a connecting rod 35 and a driving disk 36. A driving disk 36 is fixedly connected to each end of the rotating shaft 22. The driving disk 36 and the scraper 33 on the same side are connected through the connecting rod 35. A connecting seat 34 is fixedly provided on the scraper 33. One end of the connecting rod 35 is eccentrically connected to the driving disk 36, and the other end is hingedly connected to the connecting seat 34. When in use, the driving disk 36 is driven to rotate by the rotating shaft 22. Since the connecting rod 35 is eccentrically hinged to the driving disk 36, the scraper 33 can be driven to reciprocate by the driving disk 36 by utilizing the principle of the crank rocker mechanism, and when the center of the rotating shaft and the centers of the two hinge points are collinear, the maximum or minimum stroke is reached. Furthermore, according to the use requirements, the stroke of the scraper 33 can be adjusted by changing the position of the eccentric hinge of the driving disk 36.

[0044] In some embodiments, since the adhesion of flexible garbage increases after being wetted, some wet flexible floating garbage is easy to adhere to the cleaning plate 24. In order to alleviate the above problem, a scraping mechanism 5 is provided on the cleaning plate 24.

[0045] See also Figure 4 , 5 The scraping mechanism 5 includes a fixed plate 51, a pulley 54, a bracket 55, a slider 56, and a scraper 57. A slide groove 27 is provided on the cleaning plate 24, and the slider 56 is slidably connected in the slide groove 27. The slide groove 27 and the slider 56 are both inverted T-shaped structures, so that the slider 56 can only slide back and forth in the slide groove 27; the scraper 57 corresponding to the cleaning plate 24 is fixedly connected to the slider, and the scraper 57 is driven to reciprocate in the slide groove 27 to continuously scrape the garbage adhered to the cleaning plate 24, and when the bottom edge of the cleaning plate 24 is flush with the highest point of the dirt blocking rod 1, The scraper 57 reaches the maximum stroke, so that the scraper 57 can scrape away the garbage adhered to the cleaning groove 26, ensuring that the cleaning groove 26 is clean; in order to drive the slider 56 to reciprocate, a fixed plate 51 is fixedly installed on the base frame 21 through a fixed rod 53, and the rotating shaft 22 passes through the fixed plate 51 and is rotatably connected between the fixed plates 51. The fixed plate 51 is always stationary, and an eccentrically arranged annular groove 52 is opened on the fixed plate 51, and a pulley 54 is slidably connected in the annular groove 52. The pulley 54 is rotatably installed on the bracket 55, and the bracket 55 is fixedly connected to the slider 56. When the cleaning plate 24 rotates, the pulley 54 is driven to slide in the annular groove 52. Since the annular groove 52 is eccentrically arranged, the distance from the pulley 54 to the center of the fixed plate 51 changes, thereby driving the slider 56 to move back and forth in the slide groove 27, and when the bottom edge of the cleaning plate 24 is flush with the highest point of the dirt blocking rod 1, the distance between the annular groove 52 and the center of the fixed plate 51 is the farthest, so that the slider 56 reaches the maximum stroke.

[0046] Furthermore, in order to improve the stability of the brackets 55 , a reinforcing rod 58 is installed between the two brackets 55 , so as to ensure that the left and right sides of the slider 56 are subjected to uniform force.

[0047] In some embodiments, since the recovery plate 31 is an arched structure, when some longer flexible floating garbage slides from the cleaning plate 24 to the recovery plate 31, the flexible garbage may be placed on the recovery plate 31, so that part of the flexible floating garbage is located on the left side of the recovery plate 31 and the other part is located on the right side of the recovery plate 31, making it difficult for it to slide into the collection box 4 and difficult to be scraped off by the scraper 33.

[0048] See also Figure 8 , 9 In order to solve the above problems, a first blade 37 is fixedly connected to the side where the two scrapers 33 contact each other, and a baffle 32 is also provided on the side of the recovery plate 31, and a second blade 38 corresponding to the first blade 37 is fixedly connected to the baffle 32. When in use, since the movement directions of the two baffles 32 are always opposite, when the two baffles 32 meet, the first blade 37 can be used to shear the long flexible floating garbage, so that it slides toward the two sides of the recovery plate 31 respectively, and when the scraper 33 moves to the maximum or minimum stroke, the second blade 38 can be used to shear the flexible floating garbage to ensure the shearing effect; further, when the movement directions of the two scrapers 33 are always opposite, the intersection point is located at the middle position of the recovery plate 31, and the second blade 38 is provided at the front and rear ends of the recovery plate 31, which can ensure that the three shearing positions on the recovery plate 31 are evenly distributed, thereby improving the shearing effect on the flexible floating garbage.

[0049] Furthermore, in order to ensure the shearing effect, the stability of the scraper 33 needs to be ensured, see Fig. 9 Both ends of the scraper plate 33 are clamped in the T-shaped slot of the recovery plate 31 through a T-shaped joint.

[0050] In some embodiments, as the collecting box 4 collects garbage, some water will enter the collecting box 4. If it is not processed in time, the garbage will easily breed bacteria and produce odor after being soaked for a long time, affecting the surrounding environment.

[0051] See also Figure 7A detachable water collecting box 41 is arranged on the side of the collecting box 4 near the recycling mechanism 3, and a card seat 42 is arranged in the collecting box 4. The water collecting box 41 is placed on the card seat 42. When it is necessary to dump garbage, the water collecting box 41 can be taken out of the collecting box 4; the water collecting box 41 is a hollow structure, and its top surface is an inclined surface, and the side close to the recycling mechanism 3 is higher, and the side away from the recycling mechanism 3 is lower. There are also multiple rows of through holes evenly opened on the top of the water collecting box 41, and a return pipe 43 corresponding to the main drainage and irrigation channel 6 is installed at the bottom of the water collecting box 41. During use, when water and garbage enter the collecting box 4, the garbage slides down from the top surface of the collecting box 41 and falls into the collecting box 4, and most of the water enters the collecting box 41 from the through hole in the process of flowing through the top surface of the collecting box 41, and finally flows back to the main drainage and irrigation channel 6 from the return pipe 43. Since a small amount of water will enter the collecting box 4, a drainage hole can be opened at the bottom of the collecting box 4 to drain the water. A small amount of water discharged into the surrounding land is unlikely to have an impact on the environment.

[0052] On the basis of the above embodiments, since the present application uses the water flow in the main drainage and irrigation channel 6 as the power source, in order to ensure that the cleaning plate 24 can rotate normally, it can be set on the slope section of the main drainage and irrigation channel 6, thereby increasing the impact force of the water flow and ensuring the normal progress of the dredging process.

[0053] A plurality of drainage and irrigation branch channels 7 connected to farmland are arranged on both sides of the main drainage and irrigation channel 6, and a gate 8 is installed at the water inlet of each drainage and irrigation branch channel 7. By opening the gates 8 at different positions, the corresponding farmland can be irrigated. After the irrigation is completed, the gates 8 can be closed to stop the water flow from entering, thereby avoiding excessive irrigation water volume.

[0054] Specific working process:

[0055] The water flow is introduced into the drainage and irrigation main channel 6, and the floating garbage carried in the water flow is blocked by the trash blocking rod 1, and the water flow passes normally. Moreover, under the impact of the water flow, the cleaning plate 24 rotates, thereby driving the garbage to rise along the trash blocking rod 1. Under the action of gravity, the garbage will slide from the cleaning plate 24 to the recovery plate 31, and the garbage on the recovery plate 31 will fall into the collection box 4 under the action of gravity and the scraper 33. Moreover, during the rotation of the cleaning plate 24, some water will be brought up. After the water drips on the recovery plate 31, it will slide along the recovery plate 31, which can impact the garbage remaining on the recovery plate 31 and provide lubrication, so that the scraper 33 can more easily scrape off the garbage adhering to the recovery plate 31. When the garbage and water flow enter the collection box 4, dry and wet separation is carried out through the water collecting box 41, and the garbage falls into the collection box 4. The water flow flows back to the drainage and irrigation main channel 6 through the return pipe 43, and the small amount of water carried by the garbage seeps into the land through the drainage holes at the bottom of the collection box 4.

[0056] Furthermore, the adhesion of some wet flexible floating garbage will be enhanced after being wetted. Therefore, a scraping mechanism 5 is also provided on the cleaning plate 24. The water flow impacts the cleaning plate 24 to drive the rotating shaft 22 to rotate, thereby driving the pulley 54 to move in the eccentric annular groove 52, so that the slider 56 reciprocates in the slide groove 27, thereby driving the scraper 57 to scrape off the garbage adhering to the cleaning plate 24 and make it slide to the recovery plate 31.

[0057] Furthermore, since the flexible floating garbage is easily placed on the recovery plate 31 and is difficult to slide into the collection box 4, a first blade 37 is installed at the contact end of the two scrapers 33, and a second blade 38 corresponding to the first blade 37 is installed on the recovery plate 31, and the movement directions of the two scrapers 33 are made opposite, the flexible floating garbage placed on the recovery plate 31 can be sheared, so that it slides from both sides of the recovery plate 31 to the collection box 4, thereby avoiding garbage accumulation at the recovery plate 31.
