Description

Technical Field

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

[0002] Irrigation is a technical measure to replenish the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, the water requirements of crops cannot be met due to insufficient precipitation or uneven distribution, so irrigation must be carried out. In some agricultural irrigation devices, in order to reduce the waste of water resources and increase resource utilization, water pumps are generally used to draw water from rivers, lakes and other sources for irrigation.

[0003] When the water from rivers, lakes and ponds is drawn to irrigate the land, some impurities may exist in the water source, which may easily clog the water pipe. Therefore, a filter screen needs to be installed on the water pipe to filter 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, thus 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, so that 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 irrigation efficiency and affecting the normal progress of the irrigation work.

When a water flow sensor detects that the water flow is lower than a normal value, the rotating rod can be rotated to drive the cleaning brush to rotate, so that the cleaning brush performs a circular motion around the filter screen cover, thereby enabling the cleaning brush to clean a circle of the filter screen cover. This solves the problem mentioned in the above background technology that during irrigation, the surface of the filter screen cover is not cleaned by detecting the water flow, so that when the irrigation water flow is small, the water flow cannot be increased by cleaning impurities on the filter screen cover, thereby reducing the irrigation efficiency and affecting the normal progress of the irrigation work.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0031] For example, see Figure 1-Figure 11 , an irrigation device with a function of monitoring water flow, comprising a water pumping pipe 1 for being inserted underwater, one end of the water pumping pipe 1 being fixedly arranged below the water surface, a filter screen 2 being fixedly arranged at the end of the water pumping pipe 1 below the water surface, a water pump 3 being connected to the other end of the water pumping pipe 1, a water flow sensor 4 being installed on the water pumping pipe 1, a drainage pipe 5 being connected to the output end of the water pump 3, a plurality of groups of manifolds 6 being connected to the drainage pipe 5, and a nozzle 7 for irrigation being connected to the ends of the plurality of groups of manifolds 6; A disc 8 is fixed at the end of the water pump 1, a rotating rod 9 is arranged below the disc 8, a longitudinal plate 10 is slidably arranged below the rotating rod 9, and a plurality of cleaning brushes 11 for cleaning the filter screen 2 are arranged on the outer surface of the longitudinal plate 10, and the rotating rod 9 drives the cleaning brushes 11 to clean the circumference of the filter screen 2 by rotating; 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 meshes 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.

[0032] In the present technical scheme, the water pumping pipe 1 is fixedly installed below the water surface, which can be the surface of a river, a river or a lake. When performing irrigation work, the water pump 3 is first started to pump water through the water pumping pipe 1, so that the pumped water flows into the diversion pipe 6 through the drainage pipe 5, and then is sprayed out through the nozzle 7 to achieve irrigation work. When pumping water, the pumped water is filtered through the filter screen 2 set at the end of the water pumping pipe 1 to remove impurities in the water, which is convenient for irrigation work. In addition, the water flow sensor 4 is set to detect the water flow inside the water pumping pipe 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. 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 by the 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. The ring 16 drives the rotating rod 9 to rotate, and the rotating rod 9 drives the longitudinal plate 10 to rotate. 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.

[0033] 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 two adjacent groups of cleaning brushes 11, so that the gaps cannot be cleaned well, resulting in insufficient cleaning. To solve this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 11 A first annular groove 17 is formed on the lower surface of the disc 8, a first slide bar 18 is slidably disposed in the first annular groove 17, and the bottom end of the first slide bar 18 passes through the rotating rod 9 and is fixedly connected to the top of the longitudinal plate 10; A first track groove 19 is formed inside the first annular groove 17, and 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. A second annular groove 21 is provided inside the disc 8, a second slide bar 22 is slidably provided inside the second annular groove 21, the second slide bar 22 penetrates the first slide bar 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 bar 22, the rack 26 is slidably provided in the rotating groove 23; A second track groove 27 is formed on the inner wall of the second annular groove 21, and 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; The first track includes a first rising portion 191 and a first descending portion 192 which are sequentially connected and arranged in communication, and the second track groove 27 includes a second rising portion 271 and a second descending portion 272 which are sequentially connected and arranged in communication.

[0034] 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, and the first limiting protrusion 20 moves downward to drive the first sliding rod 18 to move downward, and the first sliding rod 18 moves downward to drive the longitudinal plate 10 to move downward, and the longitudinal plate 10 moves downward to drive the cleaning brush 11 to move downward, so that the cleaning brush 11 moves downward to clean the surface of the filter screen 2; when the first When the limiting boss 20 slides along the first rising portion 191, the first limiting boss 20 moves upward, and the first limiting boss 20 moves upward, driving the first slide bar 18 to move upward, and the first slide bar 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 screen cover 2 upward; through the above process, when the cleaning brush 11 rotates around the filter screen 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 adequacy of cleaning; 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 to make the first slide bar 18 move downward, the second limiting protrusion 28 slides along the second descending portion 272 to make the second slide bar 22 move downward. Since the descending distance of the second descending portion 272 is greater than the descending distance of the first descending portion 192 (such as Figure 6As 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, so that the second slide bar 22 slides inside the first slide bar 18, and the second slide bar 22 moves downward to drive the rack 26 to move downward in the rotating groove 23, and the rack 26 moves downward to drive the second gear 25 to rotate, and the rotation of the second gear 25 drives the rotating shaft 24 to rotate, and 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 screen 2; when the first limiting boss 20 slides along the first rising portion 191 and drives the first slide bar 18 to move upward, the second limiting boss 28 slides along the second rising portion 271, so that the second slide bar 22 moves upward, because 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 slide bar 22 moves downward to drive the second slide bar 22 to move downward, and the second sliding portion 271 moves downward to drive the second sliding portion 271 to move downward. Figure 6 As shown), the second slide bar 22 is prompted 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 cover 2; through the above process, when the cleaning brush 11 reciprocates up and down to clean the surface of the filter screen cover 2, the cleaning brush 11 can rotate forward and reverse, and the surface of the filter screen cover 2 is cleaned by the rotation of the cleaning brush 11, thereby increasing the adequacy of cleaning and making the cleaning efficiency better.

[0035] Embodiment 3: 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 for the cleaning brush 11 to clean them. Although the impurities inside the filter holes are small, they will also block the filter screen cover 2, thereby affecting the water flow. To address this problem, this embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 11 A positioning plate 29 is fixed to the lower surface of the rotating rod 9, 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 of the cleaning brush 11, a receiving groove 33 for the knocking column 32 to slide 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; A spring groove 34 is provided inside the rotating shaft 24, a convex plate 35 is slidably provided inside the spring groove 34, an end of the convex plate 35 is fixed to the outer surface of the push-pull rod 31, and a spring 36 is fixed between the convex plate 35 and the inner wall of the spring groove 34; 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.

[0036] In the present technical solution, a 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. Fig.10 The state shown is to rotate upwards, but not downwards. After rotating to a certain angle, it can be reset to Fig.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 to drive 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 to drive 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, 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 column 32 to move to the left instantaneously, so that the knocking column 32 knocks on 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; 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 to prevent the limiting ball 37 from sliding downward along the second vertical groove 41; Through the above process, the longitudinal plate 10 reciprocates up and down, which can drive the cleaning brush 11 to reciprocate and rotate the filter screen cover 2, while driving the knocking column 32 to knock the filter screen cover 2. Vibration makes it easier to remove impurities on the filter screen cover 2, thereby further increasing the adequacy of cleaning and improving the cleaning effect.
