Description

Technical Field

[0001] This invention relates to the field of irrigation technology in water conservancy engineering, specifically to an adjustable flow irrigation device. Background Technology

[0002] Water conservancy projects are a general term for all engineering constructions undertaken to control, utilize, and protect surface and groundwater resources and the environment. Irrigation devices in water conservancy projects are engineering and technical devices used for the allocation and precise application of water resources in farmland.

[0003] Chinese invention patent CN219395808U discloses an irrigation device for water conservancy projects, including a horizontally arranged base plate. A water tank is fixedly installed on the upper surface of the base plate, and a connecting column is vertically rotatably installed on the upper surface of the base plate. A fixing plate is horizontally fixedly installed on the upper surface of the connecting column, and a steering control mechanism is connected to the connecting column. A main pipe is horizontally fixedly installed on the upper surface of the fixing plate, and the main pipe is connected to the water tank through a water delivery mechanism. Multiple branch pipes are horizontally fixedly connected to the outer wall of the main pipe. A first electric push rod is vertically fixedly installed on the upper surface of the fixing plate, and a control rod that slides through the branch pipes is vertically fixedly installed on the upper end of the first electric push rod. This invention can flexibly adjust the irrigation direction and change the water flow, saving water and being convenient and practical. However, this existing irrigation device for water conservancy projects only uses the first electric push rod to drive the control rod to move up and down inside the branch pipe to adjust the flow rate of the branch pipe. Because the control rod cannot completely block the inner wall of the branch pipe, the water flow adjustment effect of the branch pipe is poor.

[0004] Therefore, the present invention provides an adjustable flow irrigation device to solve the above-mentioned problems. Summary of the Invention

[0005] This invention provides an adjustable flow irrigation device, aiming to solve the problems mentioned in the background art, such as the existing irrigation devices for water conservancy projects only using a first electric push rod to drive a control rod to move up and down inside the branch pipe to adjust the flow rate of the branch pipe, and the poor effect of adjusting the water flow rate of the branch pipe due to the inability of the control rod to completely block the inner wall of the branch pipe.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable flow irrigation device, comprising a support plate, a lifting structure installed on the end face of the support plate, a spraying structure installed on the lifting structure, and a water storage tank installed on the end face of the support plate and on the rear side of the lifting structure. The spraying structure includes a fixed pipe and a branch pipe installed at the outlet end of the fixed pipe. Multiple sets of spray pipes are installed on the outer wall of the branch pipe through connecting holes. The outer walls of these multiple sets of spray pipes are connected by a second housing. A second motor and a rotating shaft rotatably mounted on the second housing via bearings are installed on the left side wall of the second housing. A worm gear is provided at the drive end of the second motor. A worm wheel is installed on the upper outer wall of the rotating shaft, inside the second housing. An adjusting plate is installed at the lower end of the rotating shaft, inside the spray pipe. By setting up the spraying structure, a small adjustment function for the water flow rate through the spray pipe is achieved. Compared with existing technologies, the adjustment effect is better and more stable. This avoids the problem that existing irrigation devices in water conservancy projects only use a first electric push rod to drive a control rod to move up and down inside the branch pipe to adjust the flow rate, resulting in poor flow rate adjustment because the control rod cannot completely block the inner wall of the branch pipe.

[0007] Preferably, the lifting structure includes a first housing mounted on the end face of the support plate. A first motor and a fixed frame are mounted on the left side wall of the first housing. A transmission rod is provided at the drive end of the first motor. A driving bevel gear is mounted on the outer wall of the transmission rod on the left and right sides. Screws are rotatably mounted on the left and right sides of the fixed frame via bearings. T-blocks and driven bevel gears are threaded onto the screws. Lifting blocks are mounted on the corresponding side walls of the two sets of T-blocks.

[0008] Preferably, a water pump is installed at the bottom of the inner cavity of the water storage tank, and an output pipe is installed at the outlet end of the water pump. The outlet end of the output pipe passes through the end face of the water storage tank and is connected to a flexible hose through a connector. The inlet end of the first housing is connected to the outlet end of the flexible hose through the connector.

[0009] Preferably, a handrail is installed on the end face of the support plate and on the rear side of the water storage tank, and a roller is installed on the bottom of the support plate and at the corner. The roller is a lockable universal wheel structure.

[0010] Preferably, the lifting block is connected to the outer wall of the fixed pipe through a connecting hole, a sealing ring is provided at the connection between the water spray pipe and the rotating shaft, the lower end of the rotating shaft passes through the outer wall of the water spray pipe and extends into the interior, the right side of the second motor is rotatably connected to the other end of the worm through a bearing, the worm and the worm wheel are connected by meshing, and the adjusting plate is adapted to the inner wall of the water spray pipe.

[0011] Preferably, a rotating block is installed on the outer wall of the rotating shaft, and a limiting frame is installed at the bottom of the inner cavity of the second housing corresponding to the rotating block. The rotation range of the rotating block inside the limiting frame is 0-90 degrees.

[0012] Preferably, the first housing is rotatably connected to the lower end of the screw via a bearing, and a sliding groove is provided on the fixing frame corresponding to the screw. The fixing frame is slidably connected to the T-block via the sliding groove, and the connection between the driving bevel gear and the driven bevel gear is an meshing connection.

[0013] Beneficial effects: By setting up a spraying structure, a worm gear drives multiple sets of worm wheels to rotate in both directions, and the rotating shaft drives the adjusting plate to rotate 0-90 degrees and then from 90-0 degrees inside the spray pipe. This achieves a small adjustment function for the water flow rate through the spray pipe. Compared with existing technologies, the adjustment effect is better and more stable. It avoids the problem that existing irrigation devices in water conservancy projects only use the first electric push rod to drive the control rod to move up and down inside the branch pipe to adjust the flow rate of the branch pipe. Because the control rod cannot completely block the inner wall of the branch pipe, the water flow rate adjustment effect of the branch pipe is poor. Attached Figure Description

Detailed Implementation

[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.

[0017] Example 1 This embodiment provides an adjustable flow irrigation device, such as... Figure 1-5 As shown, the irrigation device includes a support plate 1, a lifting structure 2 is installed on the end face of the support plate 1, a spraying structure 3 is installed on the lifting structure 2, and a water storage tank 4 is installed on the end face of the support plate 1 and on the rear side of the lifting structure 2. The spraying structure 3 includes a fixed pipe 31 and a diversion pipe 32 installed at the water outlet end of the fixed pipe 31. Multiple sets of spray pipes 33 are installed on the outer wall of the diversion pipe 32 through connection holes. The outer walls of the multiple sets of spray pipes 33 are connected through a second housing 34. A second motor 35 and a rotating shaft 36 rotatably mounted on the second housing 34 via bearings are installed on the left side wall of the second housing 34. A worm gear 37 is provided at the drive end of the second motor 35. A worm wheel 38 is installed on the upper outer wall of the rotating shaft 36 inside the second housing 34. An adjusting plate 39 is installed at the lower end of the rotating shaft 36 inside the spray pipe 33.

[0018] In use, water pump 5 is started, and water pump 5 sends water from water storage tank 4 to hose 7 through output pipe 6, and then from hose 7 to fixed pipe 31. Fixed pipe 31 distributes water to multiple sets of spray pipes 33 through diversion pipe 32, and finally sprays it out through spray pipe 33. When adjusting the flow rate of spray pipe 33, the second motor 35 drives worm gear 37 to rotate forward, worm gear 37 drives multiple sets of worm wheels 38 to rotate, and worm wheels 38 drive rotating shaft 36 to rotate adjusting plate 39. Adjusting plate 39 rotates 0-90 degrees inside spray pipe 33, and spray pipe 33 goes from completely closed to completely open. During this process, the water flow rate through spray pipe 33 increases from small to large. During this process, the water flow rate can be determined at any time by stopping the motor rotation. When the axis of the water pipe 33 is parallel, the water flow is at its maximum. Conversely, the second motor 35 drives the worm gear 37 to rotate in opposite directions. The worm gear 37 drives multiple sets of worm wheels 38 to rotate in reverse. The rotating shaft 36 drives the adjusting plate 39 to rotate from 90 degrees to 0 degrees inside the water pipe 33. The water pipe 33 is then completely closed. At this time, the water flow through the water pipe 33 changes from maximum to completely stopped. This achieves a small adjustment function for the water flow through the water pipe 33. Compared with the existing technology, the adjustment effect is better and more stable. It avoids the problem that the existing irrigation devices used in water conservancy projects only use the first electric push rod to drive the control rod to move up and down inside the branch pipe to adjust the flow of the branch pipe. Because the control rod cannot completely block the inner wall of the branch pipe, the water flow adjustment effect of the branch pipe is poor.

[0019] In this embodiment, a water pump 5 is installed at the bottom of the inner cavity of the water storage tank 4. An output pipe 6 is installed at the outlet end of the water pump 5. The outlet end of the output pipe 6 passes through the end face of the water storage tank 4 and is connected to a hose 7 through a connector. The inlet end of the first housing 21 is connected to the outlet end of the hose 7 through a connector. A handrail 8 is installed on the end face of the support plate 1 and at the rear side of the water storage tank 4. A roller 9 is installed at the bottom of the support plate 1 and at the corner. The roller 9 is a lockable universal wheel structure. The device is pushed in any direction by the handrail 8 and the rollers 9, which facilitates the movement of the device. The lockable structure of the rollers 9 enables the device to be locked after it has been moved, thus improving the stability of the device. In this embodiment, the lifting block 29 is connected to the outer wall of the fixed pipe 31 through the connecting hole. A sealing ring is provided at the connection between the water spray pipe 33 and the rotating shaft 36. The lower end of the rotating shaft 36 passes through the outer wall of the water spray pipe 33 and extends into the interior. The right side of the second motor 35 is rotatably connected to the other end of the worm gear 37 through a bearing. The worm gear 37 and the worm wheel 38 are connected by meshing. The adjusting plate 39 is adapted to the inner wall of the water spray pipe 33. A rotating block 3601 is installed on the outer wall of the rotating shaft 36. A limit frame 310 is installed at the bottom of the inner cavity of the second housing 34 and corresponding to the rotating block 3601. The rotation range of the rotating block 3601 inside the limit frame 310 is 0-90 degrees. The rotating block 3601 and the limiting frame 310 limit the movement range of the rotating block 3601. The rotating block 3601 controls the rotation range of the rotating shaft 36 to 90 degrees in both directions, so that the rotating shaft 36, along with the adjusting plate 39, rotates to be parallel to the axis of the water spray pipe 33 or perpendicular to the axis of the water spray pipe 33. This allows for maximum or complete modulation of the water flow through the water spray pipe 33, resulting in better water flow regulation of the water spray pipe 33.

[0020] Example 2 Unlike Embodiment 1, the height of the branch pipe of the existing irrigation device for water conservancy projects cannot be adjusted, resulting in poor flexibility in the use of the irrigation device. Therefore, the lifting structure 2 includes a first housing 21 installed on the end face of the support plate 1. A first motor 22 and a fixed frame 23 are installed on the left side wall of the first housing 21. A transmission rod 24 is provided at the drive end of the first motor 22. A drive bevel gear 25 is installed on the outer wall of the transmission rod 24 on the left and right sides. A screw 26 is rotatably installed on the left and right sides of the fixed frame 23 through bearings. A T-block 27 and a driven bevel gear 28 are installed on the lower end of the screw 26 through threads. Lifting blocks 29 are installed on the corresponding side walls of the two sets of T-blocks 27. In use, the first motor 22 is started via the control panel, which drives the transmission rod 24 to rotate in the forward or reverse direction. The transmission rod 24 drives two sets of driven bevel gears 28 to rotate in the same direction via two sets of active bevel gears 25. The driven bevel gears 28 drive the screw 26 to rotate in the forward or reverse direction. The screw 26 drives the T-block 27 to move up or down. The T-block 27 drives the lifting block 29 to move up and down. The lifting block 29 drives the fixed pipe 31 to move up and down, thereby realizing the function of adjusting the height of the water spray pipe 33. The irrigation height of the water spray pipe 33 can be changed, avoiding the problem that the height of the branch pipe of the irrigation device used in existing water conservancy projects cannot be adjusted, resulting in poor flexibility of the irrigation device. This improves the flexibility of the device. In this embodiment, the first housing 21 is rotatably connected to the lower end of the screw 26 via a bearing. A sliding groove 2301 is provided on the fixed frame 23 corresponding to the screw 26. The fixed frame 23 is slidably connected to the T-block 27 via the sliding groove 2301. The connection between the driving bevel gear 25 and the driven bevel gear 28 is a meshing connection.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and concept of the present invention, should be covered within the scope of protection of the present invention.
