Description

Technical Field

[0001] The present invention relates to the technical field of irrigation, in particular to an irrigation device with a water flow monitoring function. Background Art

[0002] Irrigation is a technical measure used to replenish the water needed by crops. To ensure normal crop growth and high, stable yields, crops must be supplied with sufficient water. Under natural conditions, insufficient or unevenly distributed precipitation often fails to meet crop water requirements, necessitating irrigation. To reduce water waste and increase resource utilization, some agricultural irrigation systems typically use water pumps to draw water from rivers, lakes, and other sources for irrigation.

[0003] When the water from rivers and lakes is drawn to irrigate the land, there may be some impurities in the water, which may easily clog the water pipe. Therefore, a filter screen needs to be installed on the water pipe to filter out the impurities. In the process of filtering the water source through the filter screen, if a large amount of impurities cover the filter screen, it will affect the water flow rate of the water pump to extract the water source, resulting in a decrease in the water flow rate, thereby affecting the irrigation work. The existing irrigation device is not convenient for cleaning the surface of the filter screen by detecting the water flow rate during irrigation. Therefore, when the irrigation water flow rate is small, the impurities on the filter screen cannot be cleaned to increase the water flow rate, thereby reducing the efficiency of irrigation and affecting the normal progress of irrigation work.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] For example 1, please refer to Figures 1-11 An irrigation device with a water flow monitoring function includes a water pumping pipe 1 for insertion into water, one end of the water pumping pipe 1 being fixedly arranged below the water surface, a filter screen 2 being fixed to the end of the water pumping pipe 1 below the water surface, the other end of the water pumping pipe 1 being connected to a water pump 3, a water flow sensor 4 being installed on the water pumping pipe 1, an output end of the water pump 3 being connected to a drain pipe 5, a plurality of groups of manifolds 6 being connected to the drain pipe 5, and the ends of the plurality of groups of manifolds 6 being connected to nozzles 7 for irrigation;

[0035] A disc 8 is fixed to the end of the water extraction pipe 1, a rotating rod 9 is provided below the disc 8, a longitudinal plate 10 is slidably provided below the rotating rod 9, and a plurality of cleaning brushes 11 for cleaning the filter cover 2 are provided on the outer surface of the longitudinal plate 10. The rotating rod 9 drives the cleaning brushes 11 to clean the circumference of the filter cover 2 by rotating.

[0036] A motor slot 12 is provided inside the disc 8, and a waterproof motor 13 is installed inside the motor slot 12. A first gear 14 is fixed to the output end of the waterproof motor 13. A gear ring 15 is rotatably provided inside the disc 8, and the gear ring 15 is engaged with the first gear 14. A circular ring 16 is fixed to the lower surface of the gear ring 15, and the circular ring 16 is rotatably connected to the disc 8, and the end of the rotating rod 9 is fixed to the outer surface of the circular ring 16.

[0037] In the present technical solution, the water pump 1 is fixedly installed below the water surface, which can be the surface of a river, a stream or a lake. When performing irrigation work, the water pump 3 is first started to pump water through the water pump 1, so that the pumped water flows through the drainage pipe 5 to the diversion pipe 6, and then is sprayed out through the nozzle 7 to achieve irrigation work. When pumping water, the pumped water is filtered by the filter cover 2 provided at the end of the water pump 1 to remove impurities in the water, which is convenient for irrigation work. In addition, the water flow sensor 4 provided can detect the water flow inside the water pump 1 to detect whether the water flow meets the irrigation demand. The water flow sensor 4 is a prior art and is used to detect the water flow. As long as the water flow can be detected in the prior art, it is not an innovation in the present application and will not be described in detail.

[0038] When the water flow detected by the water flow sensor 4 is too small, that is, the water flow cannot meet the irrigation needs, the filter screen cover 2 is seriously clogged with filtered impurities, and the filter screen cover 2 needs to be cleaned. At this time, the water flow sensor 4 detects that the water flow is too small, and the waterproof motor 13 is started. The waterproof motor 13 drives the first gear 14 to rotate, and the first gear 14 drives the gear ring 15 to rotate, and the gear ring 15 drives the ring 16 to rotate, and the ring 16 drives the rotating rod 9 to rotate, and the rotating rod 9 drives the longitudinal plate 10 to rotate, and the rotation of the longitudinal plate 10 drives the cleaning brush 11 to rotate, so that the cleaning brush 11 performs a circular cleaning on the filter screen cover 2, which not only facilitates the cleaning of the filter screen cover 2, but also improves the adequacy of the cleaning by performing a circular motion around the filter screen cover 2.

[0039] In the second embodiment, when the cleaning brush 11 rotates to clean the surface of the filter screen 2, there will be a gap between the two adjacent groups of cleaning brushes 11, which makes it difficult to clean the gaps well, resulting in insufficient cleaning. To address this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1-11 A first annular groove 17 is provided on the lower surface of the disc 8, and a first slide rod 18 is slidably provided in the first annular groove 17. The bottom end of the first slide rod 18 passes through the rotating rod 9 and is fixedly connected to the top of the longitudinal plate 10;

[0040] A first track groove 19 is formed inside the first annular groove 17. A first limiting protrusion 20 is fixed to the end of the first slide rod 18. The first limiting protrusion 20 is slidably disposed in the first track groove 19.

[0041] A second annular groove 21 is provided inside the disc 8, and a second slide rod 22 is slidably provided in the second annular groove 21. The second slide rod 22 passes through the first slide rod 18. A rotating groove 23 is provided inside the longitudinal plate 10. A rotating shaft 24 is fixed to the outer surface of the cleaning brush 11. The rotating shaft 24 is rotatably connected to the longitudinal plate 10. A second gear 25 is fixed to the end of the rotating shaft 24. The second gear 25 is rotatably provided in the rotating groove 23. A rack 26 meshing with the second gear 25 is fixed to the end of the second slide rod 22. The rack 26 is slidably provided in the rotating groove 23.

[0042] A second track groove 27 is formed on the inner wall of the second annular groove 21. A second limiting protrusion 28 is fixed to the end of the second slide rod 22. The second limiting protrusion 28 is slidably disposed in the second track groove 27.

[0043] The first track includes a first rising portion 191 and a first descending portion 192 that are sequentially connected, and the second track groove 27 includes a second rising portion 271 and a second descending portion 272 that are sequentially connected.

[0044] In the present technical solution, when the rotating rod 9 rotates, it drives the first sliding rod 18 to slide in the first annular groove 17, and the first sliding rod 18 drives the first limiting protrusion 20 to slide in the first track groove 19. First, the first limiting protrusion 20 slides along the first descending portion 192, so that the first limiting protrusion 20 moves downward. The downward movement of the first limiting protrusion 20 drives the first sliding rod 18 to move downward. The downward movement of the first sliding rod 18 drives the longitudinal plate 10 to move downward. The downward movement of the longitudinal plate 10 drives the cleaning brush 11 to move downward, so that the cleaning brush 11 moves downward to clean the surface of the filter cover 2; when the first When the limiting protrusion 20 slides along the first rising portion 191, the first limiting protrusion 20 moves upward, and the first limiting protrusion 20 moves upward, driving the first sliding rod 18 to move upward, and the first sliding rod 18 moves upward to drive the longitudinal plate 10 to move upward, and the longitudinal plate 10 moves upward to drive the cleaning brush 11 to move upward, so that the cleaning brush 11 cleans the surface of the filter cover 2 upward; through the above process, when the cleaning brush 11 rotates around the filter cover 2, the cleaning brush 11 can reciprocate up and down, which is convenient for cleaning the position between the cleaning brushes 11 and increases the thoroughness of cleaning;

[0045] When the first slide bar 18 slides in the first annular groove 17, it drives the second slide bar 22 to slide in the second annular groove 21, and the second slide bar 22 drives the second limiting protrusion 28 to slide inside the second track groove 27. When the first limiting protrusion 20 slides along the first descending portion 192, causing the first slide bar 18 to move downward, the second limiting protrusion 28 slides along the second descending portion 272, causing the second slide bar 22 to move downward. Since the descending distance of the second descending portion 272 is greater than the descending distance of the first descending portion 192 (as shown in FIG. Figure 6 As shown in the figure, the distance that the second slide bar 22 moves downward is greater than the distance that the first slide bar 18 moves downward, prompting the second slide bar 22 to slide inside the first slide bar 18. The second slide bar 22 moves downward, driving the rack 26 to move downward in the rotating groove 23. The rack 26 moves downward, driving the second gear 25 to rotate. The rotation of the second gear 25 drives the rotating shaft 24 to rotate. The rotation of the rotating shaft 24 drives the cleaning brush 11 to rotate, so that the cleaning brush 11 rotates and cleans the filter cover 2; when the first limiting boss 20 slides along the first rising portion 191, driving the first slide bar 18 to move upward, the second limiting boss 28 slides along the second rising portion 271, causing the second slide bar 22 to move upward. Since the rising distance of the second rising portion 271 is greater than the rising distance of the second rising portion 271 (as shown in the figure), the second limiting boss 28 slides along the second rising portion 271, causing the second slide bar 22 to move upward. Figure 6 As shown), the second slide bar 22 is caused to slide inside the first slide bar 18, and the second slide bar 22 moves upward to drive the rack 26 to move upward in the rotating groove 23, and the rack 26 moves upward to drive the second gear 25 to rotate in the opposite direction, and the second gear 25 rotates in the opposite direction to drive the rotating shaft 24 to rotate in the opposite direction, and the rotating shaft 24 rotates in the opposite direction to drive the cleaning brush 11 to rotate in the opposite direction, so that the cleaning brush 11 rotates in the opposite direction to rotate and clean the filter screen 2; through the above process, when the cleaning brush 11 reciprocates up and down to clean the surface of the filter screen 2, the cleaning brush 11 can rotate forward and reverse, and the surface of the filter screen 2 is cleaned by the rotation of the cleaning brush 11, thereby increasing the adequacy of cleaning and making the cleaning efficiency better.

[0046] In the third embodiment, when cleaning the filter screen cover 2, some impurities will adhere to the filter holes of the filter screen cover 2. Since the impurities inside the filter holes of the filter screen cover 2 are generally small, it is not convenient to clean them with the cleaning brush 11. Although the impurities inside the filter holes are small, they will also cause clogging of the filter screen cover 2, thereby affecting the water flow. To address this problem, this embodiment is an improvement made on the basis of the second embodiment. For details, please refer to Figures 1-11 A positioning plate 29 is fixed to the lower surface of the rotating rod 9, and a slide groove 30 is provided on the outer surface of the positioning plate 29. A push-pull rod 31 is slidably provided in the slide groove 30. A knocking column 32 is provided at the center position of the cleaning brush 11. A receiving groove 33 for sliding the knocking column 32 is provided inside the base of the cleaning brush 11. The push-pull rod 31 passes through the second gear 25 and the rotating shaft 24, and the end of the push-pull rod 31 is fixedly connected to the knocking column 32;

[0047] A spring groove 34 is formed inside the rotating shaft 24. A convex plate 35 is slidably provided in the spring groove 34. The end of the convex plate 35 is fixed to the outer surface of the push-pull rod 31. A spring 36 is fixed between the convex plate 35 and the inner wall of the spring groove 34.

[0048] A limiting ball 37 is fixed at the end of the push-pull rod 31, and the interior of the slide groove 30 is provided with an inclined groove 38 for the limiting ball 37 to slide, a first vertical groove 39, a knocking groove 40 and a second vertical groove 41, and a rotating plate 42 is elastically provided at the connection between the inclined groove 38 and the second vertical groove 41.

[0049] In this technical solution, the rotating plate 42 is provided, and the rotating plate 42 is rotatably connected to the inner wall of the positioning plate 29 through a torsion spring. The rotating plate 42 can only be pressed Figure 10 The state shown is turned upwards and cannot be turned downwards. After turning a certain angle, it can be reset to Figure 10 The state shown; when the longitudinal plate 10 reciprocates up and down, when the longitudinal plate 10 moves downward, the longitudinal plate 10 drives the push-pull rod 31 to move downward, and the push-pull rod 31 moves downward, driving the limiting ball 37 to move downward. Since the rotating plate 42 cannot rotate downward at this time, the limiting ball 37 slides downward along the inclined groove 38, and the limiting ball 37 drives the push-pull rod 31 to move right, and the push-pull rod 31 moves right, driving the knocking column 32 to move right. At the same time, the push-pull rod 31 drives the convex plate 35 to move right, so that the convex plate 35 compresses the spring 36, so that the spring 36 is compressed and stored force, and then the limiting ball 37 continues to slide downward along the first vertical groove 39. When the limiting ball 37 slides to the right end of the knocking groove 40, the limiting ball 37 loses its resistance, and the spring 36 unloads the force, so that The push-pull rod 31 moves to the left instantaneously, and the push-pull rod 31 moves to the left instantaneously, driving the knocking post 32 to move to the left instantaneously, so that the knocking post 32 knocks the surface of the filter screen cover 2, and the impurities on the filter screen cover 2 are facilitated to fall off through the vibration effect; when the longitudinal plate 10 moves upward, the longitudinal plate 10 drives the push-pull rod 31 to move upward, and the push-pull rod 31 drives the limiting ball 37 to move upward along the second vertical groove 41, and when the limiting ball 37 slides to the rotating plate 42, it contacts the rotating plate 42, causing the rotating plate 42 to rotate upward until the limiting ball 37 moves upward to a position exceeding the rotating plate 42, at which time the rotating plate 42 is reset by the action of the torsion spring, so that the rotating plate 42 limits the limiting ball 37, preventing the limiting ball 37 from sliding downward along the second vertical groove 41;

[0050] Through the above process, the longitudinal plate 10 reciprocates up and down, which can drive the cleaning brush 11 to clean the filter cover 2 up and down and rotate it for cleaning, while driving the knocking column 32 to knock the filter cover 2. The vibration makes it easier to remove impurities on the filter cover 2, thereby further increasing the adequacy of cleaning and improving the cleaning effect.

[0051] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
