Description

Technical Field

[0001] This invention relates to the field of irrigation diversion, specifically to a water-saving irrigation diversion regulation device. Background Technology

[0002] As a major agricultural producer, my country's agricultural irrigation accounts for over 60% of the country's total water consumption, making it the largest consumer of water resources. With the increasing prominence of water scarcity, water-saving irrigation has become a core direction for ensuring sustainable agricultural development and improving water resource utilization efficiency. Irrigation diversion and regulation devices are the core actuators of water-saving irrigation systems, primarily responsible for switching irrigation pipelines on and off, distributing flow across multiple branches, and controlling irrigation in designated zones. Their performance directly determines the water-saving effect, operational stability, and irrigation uniformity of the irrigation system.

[0003] Currently, most diversion regulation devices used in farmland and garden irrigation adopt a rotary valve core switching structure combined with a parallel diversion branch design. An electric actuator drives the rotary valve core to rotate, achieving on / off switching and flow regulation of different irrigation branches, which can meet the basic needs of zoned irrigation. However, in long-term practical application, existing diversion regulation devices still have many unresolved technical defects, seriously restricting the improvement of water-saving irrigation effects and the long-term stable operation of the system.

[0004] First, existing parallel branch systems generally adopt a shared inlet chamber design, with the inlet pressure of each branch coming from the same source, resulting in serious hydraulic coupling problems. Especially at the moment of branch opening and closing, significant water hammer impact and sudden water pressure changes will occur in the pipeline. This will not only further aggravate the hydraulic coupling interference between branches, but also cause continuous impact on the irrigation pipeline, drippers, sprinklers and other terminal components, leading to component damage, pipeline leakage and significantly shortening the service life of the system. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a water-saving irrigation diversion and regulation device that solves the problem of significant water hammer impact and sudden water pressure changes in the pipeline at the moment of branch opening and closing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A water-saving irrigation diversion and regulation device includes a housing, a rotating assembly, a valve assembly, and a water outlet assembly. The housing has a storage slot inside, and a rotating seat is rotatably connected to the bottom of the storage slot. A cover plate is bolted to the upper edge of the housing, and a placement rack is provided above the cover plate. An electric push rod is rotatably connected inside the placement rack, and a rotating shaft is rotatably connected to the telescopic end of the electric push rod. The rotating shaft passes through the cover plate and is fixedly connected to the rotating seat. The rotating seat has two through slots for liquid flow inside, and a support cylinder is fixedly connected in each through slot. A sliding groove is opened inside the support cylinder, and a buffer seat is slidably connected in the sliding groove. A water inlet pipe is fixedly connected to the outer shell, and the valve assembly is connected to the water inlet pipe. The water outlet assembly includes two flow pipes fixedly installed in the water outlet pipe, a mounting plate, a rotating wheel, a brush, a mounting frame, a filter screen, a connecting pipe, multiple drain pipes, and an electrically controlled valve; The two flow tubes are correspondingly arranged with the two through slots of the rotating seat. The top and bottom of the inner wall of the flow tube are fixed with mounting plates. The inner wall of the mounting plates is rotatably connected with rotating wheels. The outer wall of the rotating wheels is fixed with brushes. The front end of the inner wall of the flow tube away from the outer shell is fixed with a mounting frame. The inner wall of the mounting frame is fixed with a filter screen. Through the above technical solution, by setting the corresponding double groove of the rotating seat and the flow pipe and selectively connecting them, hydraulic coupling between branches can be effectively avoided, and sudden changes in water pressure and flow rate in other branches can be prevented when any branch is opened, closed or adjusted. In addition, the sliding of the buffer seat along the slide groove and the elastic deformation of the return spring can offset the sudden change in water pressure and water hammer impact, and prevent pressure fluctuations from being transmitted to other branches without attenuation.

[0007] Furthermore, the valve assembly includes a valve body, a mounting plate, a screw, a valve plate, and a knob; the valve body is fixedly installed on the water inlet pipe and communicates with the inside of the water inlet pipe, the mounting plate is fixed to the upper end of the valve body, the screw is threaded through the mounting plate, the lower end of the screw is rotatably connected to the valve plate, the valve plate is slidably engaged with the inner wall of the valve body, and the upper end of the screw is fixedly connected to the knob; Through the above technical solution, by fixing the valve body to the water inlet pipe and communicating with its interior, and with the cooperation structure of the mounting plate, screw, valve plate and knob, rotating the knob can drive the screw to rotate, thereby driving the valve plate to slide along the inner wall of the valve body, thus enabling the opening and closing of liquid transportation.

[0008] Furthermore, the rotation of the rotating seat can selectively connect or disconnect its internal through groove from the corresponding flow pipe; Through the above technical solution, the rotation of the rotating seat can achieve selective connection or isolation between its internal through groove and the corresponding flow pipe. This can quickly switch between different irrigation branches to meet the needs of zoned irrigation, while avoiding the hydraulic coupling problem caused by the simultaneous conduction of two branches, eliminating mutual interference of flow between branches, and ensuring the stability and accuracy of diversion regulation.

[0009] Furthermore, the bristles of the brush are closely attached to the filter screen, which enables the water flow to impact and rotate the rotating wheel, thereby achieving automatic cleaning of the inner wall of the flow pipe and the filter screen, avoiding impurities from adhering and clogging the pipe, reducing maintenance costs, and ensuring the flow efficiency of the device. With the above technical solution, multiple drain pipes are evenly spaced along the lower end of the flow pipe and correspond to the area below the brush. Combined with an independently controllable electromagnetic control valve, it can quickly discharge the impurities swept by the brush during water flushing, avoiding impurity accumulation and blockage, and can also control the on / off state of the control valve individually.

[0010] Furthermore, the multiple drain pipes are evenly spaced along the lower end of the flow pipe and are opposite to the bottom of the brush. The electric control valve is an electromagnetic control valve, which can independently control the on / off state of the corresponding drain pipe. With the above technical solution, multiple drain pipes are evenly spaced along the lower end of the flow pipe and correspond to the area below the brush. With the help of independently controllable electromagnetic valves, the impurities cleaned by the brush can be discharged quickly and periodically during diversion, avoiding the accumulation and blockage of impurities.

[0011] Furthermore, the top and bottom surfaces of the support cylinder are provided with limit grooves, a return spring is fixedly connected to the inner wall of the limit groove, a limit block is slidably connected to the inner wall of the return spring, and the limit block is fixedly connected to the buffer seat. Through the above technical solution, the limiting block is fixedly connected to the buffer seat, which can limit and guide the sliding of the buffer seat along the slide groove, avoid jamming and displacement, and at the same time, the elastic deformation of the reset spring can offset the water flow impact and pressure change, reducing hydraulic coupling interference.

[0012] Furthermore, the telescopic end of the electric push rod is rotatably connected to a rotating shaft, which vertically penetrates the cover plate and is fixedly connected to the rotating seat coaxially. Through the above technical solution, the electric push rod can stably transmit driving force through the rotating shaft when it extends or retracts, driving the rotating seat to rotate, ensuring the connection between the internal groove of the rotating seat and the flow pipe, and realizing the diversion.

[0013] This invention provides a water-saving irrigation diversion and regulation device. It has the following beneficial effects: This invention provides a water-saving irrigation diversion and regulation device. By the corresponding arrangement of the rotating seat double groove and the flow pipe and the selective connection design, hydraulic coupling between branches can be effectively avoided, and sudden changes in water pressure and flow rate in other branches can be prevented when any branch is opened, closed or regulated. In addition, the sliding of the buffer seat along the slide groove and the elastic deformation of the return spring can offset the sudden change in water pressure and water hammer impact, and prevent pressure fluctuations from being transmitted to other branches without attenuation.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0017] like Figure 1-9 As shown, this embodiment of the invention provides a water-saving irrigation diversion and regulation device, including a housing 1, a rotating assembly 2, a valve assembly 3, and a water outlet assembly 4. The housing 1 has a storage slot 11 inside, and a rotating seat 25 is rotatably connected to the bottom of the storage slot 11. A cover plate 12 is bolted to the upper edge of the housing 1, and a placement rack 21 is provided above the cover plate 12. An electric push rod 22 is rotatably connected inside the placement rack 21. A rotating shaft 23 is rotatably connected to the telescopic end of the electric push rod 22. The rotating shaft 23 passes through the cover plate 12 and is fixedly connected to the rotating seat 25. The rotating seat 25 has two through slots for liquid flow inside. Each through slot is fixedly connected to a support cylinder 26. The support cylinder 26 has a sliding groove 27 inside. A buffer seat 28 is slidably connected inside the sliding groove 27. The outer shell 1 is fixedly connected to a water inlet pipe 13. The valve assembly 3 is connected to the water inlet pipe 13. The water outlet assembly 4 includes two flow pipes 41 fixedly installed on the water outlet pipe 14, a mounting plate 45, a rotating wheel 46, a brush 47, a mounting frame 48, a filter screen 49, a connecting pipe 42, multiple drain pipes 43, and an electric control valve 44. Two flow pipes 41 are correspondingly arranged with two through slots of the rotating seat 25. The top and bottom of the inner wall of the flow pipe 41 are fixed with mounting plates 45. The inner wall of the mounting plates 45 is rotatably connected with rotating wheels 46. The outer wall of the rotating wheels 46 is fixed with brushes 47. The front end of the inner wall of the flow pipe 41 away from the outer shell 1 is fixed with a mounting frame 48. The inner wall of the mounting frame 48 is fixed with a filter screen. By using the corresponding arrangement of the rotating seat double groove and the flow pipe and the selective connection design, hydraulic coupling between branches can be effectively avoided, and sudden changes in water pressure and flow rate in other branches can be prevented when any branch is opened, closed or adjusted. In conjunction with the sliding of the buffer seat along the groove and the elastic deformation of the return spring, the sudden changes in water pressure and water hammer impact can be offset, and pressure fluctuations can be prevented from being transmitted to other branches without attenuation.

[0018] The valve assembly 3 includes a valve body 31, a mounting plate 32, a screw 33, a valve plate 34, and a knob 35. The valve body 31 is fixedly installed on the water inlet pipe 13 and communicates with the inside of the water inlet pipe 13. The mounting plate 32 is fixed to the upper end of the valve body 31. The screw 33 is threaded through the mounting plate 32. The lower end of the screw 33 is rotatably connected to the valve plate 34. The valve plate 34 is slidably fitted with the inner wall of the valve body 31. The upper end of the screw 33 is fixedly connected to the knob 35. By fixing the valve body 31 to the water inlet pipe 13 and communicating with its interior, and with the cooperation structure of the mounting plate 32, screw 33, valve plate 34 and knob 35, rotating the knob 35 can drive the screw 33 to rotate, thereby driving the valve plate 34 to slide along the inner wall of the valve body 31, thus enabling the opening and closing of liquid transportation.

[0019] The rotation of the rotating seat 25 allows its internal through groove to be selectively connected to or disconnected from the corresponding flow pipe 41; By rotating the rotating seat 25, selective connection or disconnection between its internal through groove and the corresponding flow pipe 41 can be achieved. This can quickly switch between different irrigation branches to meet the needs of zoned irrigation, while avoiding hydraulic coupling problems caused by simultaneous conduction of two branches, eliminating mutual interference of flow between branches, and ensuring the stability and accuracy of diversion regulation.

[0020] The bristles of the brush 47 fit tightly against the filter screen 49, which allows the water flow to impact and rotate the rotating wheel 46, thereby achieving automatic cleaning of the inner wall of the flow pipe 41 and the filter screen 49, preventing impurities from adhering and clogging the pipe, reducing maintenance costs, and ensuring the flow efficiency of the device. Multiple drain pipes 43 are evenly spaced along the lower end of the flow pipe 41 and correspond to the area below the brush 47. They are equipped with an independently controllable electromagnetic control valve 44, which can quickly discharge the impurities cleaned by the brush 47 when the water flows, preventing impurities from accumulating and clogging the pipes. The valve 44 can also be turned on and off independently.

[0021] Multiple drain pipes 43 are evenly spaced along the lower end of the flow pipe 41 and are opposite to the bottom of the brush 47. The electric control valve 44 is an electromagnetic control valve that can independently control the on / off state of the corresponding drain pipe 43. Multiple drain pipes 43 are evenly spaced along the lower end of the flow pipe 41 and correspond to the area below the brush 47. With the help of an independently controllable electromagnetic control valve 44, the impurities cleaned by the brush 47 can be discharged periodically and quickly during diversion, preventing impurities from accumulating and clogging.

[0022] The top and bottom surfaces of the support cylinder 26 are provided with limit grooves 29. A return spring 210 is fixedly connected to the inner wall of the limit groove 29. A limit block 211 is slidably connected to the inner wall of the return spring 210. The limit block 211 is fixedly connected to the buffer seat 28. The limiting block 211 is fixedly connected to the buffer seat 28, which can limit and guide the sliding of the buffer seat 28 along the slide groove 27 to avoid jamming and displacement. At the same time, the elastic deformation of the reset spring 210 can offset the impact of water flow and pressure change, and reduce hydraulic coupling interference.

[0023] The telescopic end of the electric push rod 22 is rotatably connected to a rotating shaft 23, which vertically passes through the cover plate 12 and is coaxially and fixedly connected to the rotating seat 25. When the electric push rod 22 extends or retracts, it can stably transmit driving force through the rotating shaft 23, drive the rotating seat 25 to rotate, ensure the connection between the internal groove of the rotating seat 25 and the flow pipe 41, and realize the diversion.

[0024] Working principle: Liquid enters the device through the inlet pipe 13 fixedly connected to the outer casing 1. The knob 35 of the rotating valve assembly 3 drives the screw 33 to rotate, which in turn drives the valve plate 34 to slide along the inner wall of the valve body 31, thus opening and closing the liquid delivery in the inlet pipe 13. When the electric push rod 22, rotatably connected inside the placement rack 21, extends or retracts, it transmits a driving force through the rotating shaft 23 rotatably connected to its extension end. The rotating shaft 23 vertically penetrates the cover plate 12 and is coaxially fixedly connected to the rotating seat 25, driving the rotating seat 25, rotatably connected to the bottom of the storage tank 11, to rotate. The rotation of the rotating seat 25 allows the two through slots inside to selectively connect or disconnect with the two flow pipes 41 of the water outlet assembly 4, realizing the switching of different irrigation branches while avoiding the hydraulic coupling problem caused by the simultaneous conduction of two branches. Liquid flows through the rotating seat 25... The liquid enters the corresponding support cylinder 26 through the channel 5. The buffer seat 28 inside the support cylinder 26 slides along the sliding groove 27. In conjunction with the elastic deformation of the limiting groove 29 on the top and bottom surfaces of the support cylinder 26, it offsets the sudden change in water pressure and the impact of water hammer, and avoids the pressure fluctuations from being transmitted to other branches without attenuation. After the liquid enters the flow pipe 41, the water flow impacts the rotating wheel 46 that is rotatably connected to the support plate 45 at the top and bottom of the inner wall of the flow pipe 41. This drives the brush 47 fixed on the outer wall of the rotating wheel 46 to rotate. The bristles of the brush 47 are in close contact with the inner wall of the flow pipe 41 and the filter screen 49 fixed in the mounting frame 48, so as to achieve automatic cleaning of the inner wall of the flow pipe 41 and the filter screen 49. Then, the electromagnetic control valve 44 is activated to quickly discharge some of the sewage along the flow pipe 41, which is evenly distributed at intervals and corresponds to the multiple drain pipes 43 below the brush 47, so as to avoid the accumulation and blockage of impurities.
