Description

Technical Field

[0001] This invention belongs to the field of high-standard farmland construction technology, specifically relating to a smart drainage system for farmland. Background Technology

[0002] Improving the basic functions of farmland—irrigation in drought and drainage in floods—is an effective measure to ensure a good harvest regardless of drought or flood, and it is also a fundamental requirement for the construction of high-standard farmland. In the process of constructing an integrated irrigation and drainage farmland system, integrated irrigation and drainage networks have significant advantages over traditional canals.

[0003] In recent years, farmland irrigation networks have covered most parts of the country. However, during the improvement of these networks, a phenomenon of "emphasizing irrigation but neglecting drainage" has emerged. When rainfall is heavy, farmland is prone to waterlogging, causing widespread flooding and damaging many crops, resulting in crop failure and the inability to continue planting. Currently, drainage equipment is easily damaged by impurities in the water. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a smart drainage system for farmland to solve the problem that excessive impurities in the water during flood drainage in existing devices can damage the drainage equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention discloses a smart drainage system for farmland, characterized in that it includes a water storage tank, an inlet pipe connected to the upper part of the water storage tank, a current detection device installed inside the inlet pipe, and a debris removal device connected to the upper part of the inlet pipe. The debris removal device includes a coarse debris filter plate, a sliding plate, a collection trough, a filter screen, a slag discharge port, and a slag outlet. The coarse debris filter plate is V-shaped with a rounded bottom end and passes through the inlet pipe. The sliding plate is slidably connected to the coarse debris filter plate and is arc-shaped. Both the sliding plate and the coarse debris filter plate have multiple slag discharge ports. Each slag discharge port has a filter screen on its front side, and the filter screen is located on the sliding plate. The collection trough is located below the coarse debris filter plate and is connected to the slag outlet.

[0007] Furthermore, a sludge removal device is installed inside the water storage tank. The sludge removal device includes: an impeller, a first bevel gear, a second bevel gear, a first fixed rod, a second fixed rod, a rotating shaft, a scraper, an outer protective cylinder, a spiral transmission rod, and a motor. One end of the first fixed rod is connected to the inside of the water storage tank, and the other end is rotatably connected to the impeller. The other end of the impeller is fixedly connected to the first bevel gear. The second bevel gear is located below the first bevel gear and meshes with it. The rotating shaft is fixedly connected to the second bevel gear, and its lower end is connected to the scraper. One end of the second fixed rod is connected to the inside of the water storage tank, and the other end is rotatably connected to the rotating shaft. The water storage tank protrudes to one side, and the outer protective cylinder is located in the protruding area of ​​the water storage tank. One end of the outer protective cylinder extends out of the water storage tank, and the spiral transmission rod is located inside the outer protective cylinder. One end of the spiral transmission rod is connected to the motor.

[0008] Furthermore, the current detection device includes: a connecting ring, a mounting strip, a current detector, a mounting ring, an annular guide groove, a ball bearing rod, an insulating protective sleeve, a turbine blade, a central rod, a permanent magnet block, and a winding coil. The connecting ring is located inside the water inlet pipe. There are two connecting rings arranged opposite each other. The mounting strip is located between the two connecting rings. An annular guide groove is formed on the inner wall of each of the two connecting rings. The ball bearing rod is located inside the annular guide groove and is slidably connected to the annular guide groove. The other end of the ball bearing rod is connected to the mounting ring. There are two mounting rings. The mounting ring is connected to the turbine blade. The central rod is located between the two mounting rings.

A winding coil made of copper wire is provided inside the insulating protective sleeve. A current detector is provided outside the water inlet pipe. The current detector is electrically connected to the winding coil at the corresponding position.

[0009] Furthermore, the slag discharge ports of the sliding plate and the coarse impurity filter plate are staggered, and the two slag discharge ports have the same area.

[0010] Furthermore, there are two slag discharge ports, which are arranged opposite each other on both sides of the water inlet pipe.

[0011] Furthermore, a fixing frame is connected between the motor and the outer casing.

[0012] The beneficial effects of this invention are as follows:

[0013] This invention discloses a smart drainage system for farmland. A debris removal device filters impurities of varying sizes from the water while ensuring smooth water flow. A coarse filter plate removes large impurities, and its large pores ensure a high water flow rate, preventing disruption to drainage. Multiple filter screens on a sliding plate filter out fine impurities; these screens, arranged vertically, effectively remove floating impurities. A staggered set of discharge ports prevents water from flowing into these ports; rotating the sliding plate aligns two discharge ports, causing the water flow to carry fine impurities into a collection trough. A silt removal device removes silt from the reservoir, ensuring sufficient water storage capacity. The hydraulically driven silt removal device reduces energy consumption and construction difficulty, improving practicality. A current detection device uses water flow rate to determine water level; if the water level is too high, the current detector issues an alarm, allowing for appropriate drainage methods.

Detailed Implementation

[0025] like Figures 1-5 As shown, this invention discloses a smart drainage system for farmland, comprising a water storage tank 1 located below the soil layer. A rotating cover 5 is provided on the water storage tank 1. An inlet pipe 4 is connected to the upper part of the water storage tank 1, and a current detection device is installed inside the inlet pipe 4. A debris removal device 2 is connected to the upper part of the inlet pipe 4, located above the soil layer. The debris removal device 2 includes: a coarse debris filter plate 21, a sliding plate 22, a collection trough 23, a filter screen 25, a slag discharge port 26, and a slag outlet 24. The coarse debris filter plate 21 is V-shaped with a rounded bottom end, and it passes through the inlet pipe 4. The coarse debris filter plate 21 is located on both sides of the inlet pipe 4, allowing water to flow into the inlet pipe 4 from both ends. The sliding plate 22 is slidably connected to the coarse debris filter plate 21, and is arc-shaped, fitting snugly against the coarse debris filter plate 21. The sliding plate 22 slides laterally on the coarse debris filter plate 21. Both the sliding plate 22 and the coarse filter plate 21 are provided with slag discharge ports 26. The slag discharge ports 26 of the sliding plate 22 and the coarse filter plate 21 are staggered, and the areas of two slag discharge ports 26 are the same size. There are multiple slag discharge ports 26, and each slag discharge port 26 has a filter screen 25 on its front side. The filter screens 25 are arranged vertically on the sliding plate 22. The collection trough 23 is located on the lower side of the coarse filter plate 21 and is connected to the slag discharge port 24. There are two slag discharge ports 24, which are arranged opposite each other on both sides of the water inlet pipe 4.

[0026] The working principle of the above scheme is as follows: Large impurities in the water are first discharged through the coarse filter plate 21. The large filter holes also ensure a large water flow, preventing any impact on drainage speed. Fine impurities are then located on the filter screen 25. The sliding plate 22 is rotated laterally to overlap the two staggered discharge ports 26. The impurities fall into the discharge ports 26 and enter the collection tank 23. When the discharge ports 26 overlap, water also flows into the collection tank 23, thus carrying the impurities out of the collection tank 23 and out through the discharge port 24. The filtered water then enters the inlet pipe 4 and flows into the reservoir 1. By opening the rotating cover 5, a water pump can be placed in the reservoir 1 to irrigate the land during the dry season.

[0027] The beneficial effects of the above scheme are as follows: the impurity removal device 2 can filter impurities in the water in an orderly manner according to their size, while also ensuring the smooth flow of water; the coarse impurity filter plate 21 first discharges large impurities from the water, and the large filter holes also ensure a large water flow, avoiding affecting the drainage rate; the multiple filter screens 25 set on the sliding plate 22 can also filter out small impurities, and because small impurities are buoyant in flowing water, the filter screens 25 are arranged vertically to filter impurities; the staggered slag discharge ports 26 prevent water from flowing into the slag discharge ports 26, and by rotating the sliding plate 22, the two slag discharge ports 26 overlap, at which point the water flow carries the small impurities into the collection tank 23.

[0028] In one embodiment of the present invention, such as Figures 2-4 As shown, a sludge removal device 3 is installed inside the water storage tank 1. The sludge removal device 3 includes: an impeller 32, a first bevel gear 33, a second bevel gear 391, a first fixed rod 392, a second fixed rod 31, a rotating shaft 34, a scraper 35, an outer protective sleeve 36, a spiral transmission rod 37, and a motor 39. One end of the first fixed rod 392 is connected to the inside of the water storage tank 1, and the other end is rotatably connected to the center of the impeller 32. The impeller 32 is located below the water inlet pipe 4, and one side of the impeller 32's blades is perpendicular to the bottom of the water inlet pipe 4. The other end of the center of the impeller 32 is fixedly connected to the center of the first bevel gear 33. The second bevel gear 391 is located below the first bevel gear 33 and meshes with it. The rotating shaft 34 is located below the second bevel gear 391 and is fixedly connected to it. The lower end of the rotating shaft 34 is connected to the scraper 35. The scraper 35 is located at the bottom of the water storage tank 1 and is arc-shaped. One end of the second fixing rod 31 is connected to the inside of the water storage tank 1, and the other end is rotatably connected to the rotating shaft 34. The water storage tank 1 protrudes from one side, and the outer protective cylinder 36 is located in the protruding area of ​​the water storage tank 1. The upper end of the outer protective cylinder 36 extends out of the water storage tank 1, and the lower end of the outer protective cylinder 36 is close to the bottom of the water storage tank 1. The spiral transmission rod 37 is located inside the outer protective cylinder 36 and rotatably connected to it. One end of the spiral transmission rod 37 is connected to the output shaft of the motor 39, which is located outside the soil layer. A fixing frame 38 connects the motor 39 and the outer protective cylinder 36.

[0029] The working principle of the above scheme is as follows: Water flows through the inlet pipe 4 and impacts the impeller 32. The impeller 32 rotates under force, driving the first bevel gear 33 to rotate, which in turn drives the second bevel gear 391 to rotate. The second bevel gear 391 rotates the scraper 35 through the rotating shaft 34. The scraper 35 scrapes the silt at the bottom of the water storage tank 1, and the silt accumulates at the end of the scraper 35 closest to the water storage tank 1. The scraper 35 then scrapes the silt to the protruding area of ​​the water storage tank 1. When the silt is concentrated in the protruding area, the motor 39 is turned on. The motor 39 drives the spiral transmission rod 37 to rotate, and the silt is carried out of the water storage tank 1 by the spiral transmission rod 37.

[0030] The beneficial effects of the above scheme are as follows: the silt removal device 3 can remove the silt from the reservoir 1, ensuring the water storage capacity of the reservoir 1. The silt removal device 3 is hydraulically driven, which reduces energy consumption and construction difficulty and improves practicality. Since the reservoir 1 is located in the soil layer, it is not suitable to install an electric drive device inside it. The hydraulic drive facilitates the use of the device.

[0031] In one embodiment of the present invention, such as Figures 6-8 As shown, the current detection device includes: a connecting ring 6, a mounting strip 7, a current detector 8, a mounting ring 9, an annular guide groove 10, a ball bearing rod 11, an insulating protective sleeve 12, a turbine blade 13, a central rod 14, a permanent magnet block 15, and a winding coil 16. The connecting ring 6 is located inside the water inlet pipe 4 and is rotatably connected to the water inlet pipe 4. There are two connecting rings 6 arranged opposite each other. Multiple mounting strips 7 are located between two connecting rings 6. Annular guide grooves 10 are formed on the inner walls of both connecting rings 6. One end of the ball bearing rod 11 is located within the annular guide groove 10 and is slidably connected to it. The other end of the ball bearing rod 11 is connected to the mounting ring 9. There are two mounting rings 9. The mounting ring 9 is connected to the turbine blade 13. The central rod 14 is located between the two mounting rings 9 and passes through the permanent magnet block 15. The permanent magnetic block 15 is externally connected to the insulating protective sleeve 12, and the insulating protective sleeve 12 is internally provided with a winding coil 16, which is made of copper wire. A current detector 8 is externally provided on the water inlet pipe 4, with one end of the current detector 8 extending out of the water inlet pipe 4. The current detector 8 is electrically connected to the winding coil 16 at the corresponding position.

[0032] The working principle of the above scheme is as follows: When water flows through the inlet pipe 4, the water flow drives the turbine blades 13 to rotate, which in turn drives the permanent magnet block 15 to rotate. The magnetic field at the winding coil 16 changes, thereby generating current, which is fed back to the current detector 8. The faster the water flow, the stronger the signal of the current detector 8, so as to remind people that the water flow is too large and multiple drainage methods need to be used for rapid drainage.

[0033] The beneficial effects of the above scheme are: by using a current detection device to determine the water level by the water flow rate, the current detector 8 will issue a stronger alarm when the water level is too high, so that people can know to use various methods to drain the water and avoid excessive losses.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
