Description

Technical Field

[0001] This utility model relates to the field of irrigation diversion technology, and more specifically, to a farmland irrigation diversion device. Background Technology

[0002] Farmland irrigation refers to water conservancy projects aimed at increasing agricultural production. It involves constructing and utilizing various water conservancy projects to regulate and improve farmland moisture conditions and regional water resources, enhance resilience against natural disasters, and promote a virtuous cycle of the ecological environment, thereby benefiting crop production. Farmland irrigation projects, aimed at increasing agricultural production, utilize irrigation canals to connect irrigation sources and waterways to irrigate the land. These canals transport and distribute water from the source to various parts of the irrigated area, and diversion devices are required when diverting water.

[0003] However, existing irrigation diversion devices have the following problems when in use: Existing diversion devices typically use several water pipes and pumps connected together. During use, silt in the water can easily cause blockages in the pipes, affecting farmland irrigation. Furthermore, when changing the water flow distribution, water in the pipe with the lower flow rate cannot flow to the other pipes, resulting in excessive pressure inside the pipe. This not only affects irrigation stability but may also damage the pipes or device components due to excessive pressure. In addition, clearing the blocked pipes requires complete disassembly, which reduces work efficiency and increases workload.

[0004] This invention can efficiently purify irrigation water sources, evenly distribute water flow, and precisely regulate flow. It can protect the internal structure, improve water resource utilization, reduce maintenance costs, adapt to diverse farmland scenarios, and provide reliable support for efficient agricultural production.

[0015] 1. By incorporating flow chambers, partition plates, water inlets, and through holes, the flow chambers, in conjunction with the partition plates at each level, achieve orderly water flow distribution through a progressively increasing number of chambers. This allows concentrated water flow to naturally disperse, preventing excessive or insufficient water volume in certain areas. The water inlets match the corresponding chambers to ensure a stable water flow transition and reduce impact. The through holes balance the pressure in each sub-chamber, eliminating differences in water flow distribution and ensuring uniform flow of multiple streams to meet the irrigation needs of different areas. This structure requires no complex power source, achieving flow distribution solely through physical separation and guidance, reducing the risk of failure, improving device reliability, and simultaneously reducing energy consumption and losses caused by water flow turbulence, thus contributing to water conservation and efficiency. It is suitable for diverse farmland irrigation scenarios. 2. By installing filter plates, large particles such as mud, sand, and weeds in the irrigation water source can be effectively intercepted, preventing them from entering the flow chamber, water outlet, and through holes inside the diversion device. This prevents these key parts from being blocked and ensures the smooth flow of water. This not only reduces device failures caused by blockages and lowers the frequency of cleaning and maintenance, but also protects components such as partition plates and valves from wear by debris, extends the service life of the device, and ensures a stable and efficient diversion process, providing a basic guarantee for subsequent precise diversion and uniform irrigation. 3. Equipped with valves, baffles, slide bars, and limit blocks, the valves and baffles work together to flexibly adjust the water flow cross-section in the outlet pipe, achieving precise control of the water output to meet the water demand of different irrigation scenarios. The slide bars limit the movement direction of the baffles, ensuring smooth lifting and lowering without deviation, thus improving adjustment accuracy. The limit blocks effectively prevent excessive movement of the baffles, avoiding structural damage and ensuring safe operation of the device. The overall design is easy to operate, and the smooth control of water flow can be achieved through mechanical transmission, enhancing the practicality and durability of the device and adapting to the complex environment of farmland irrigation. 4. In summary, this type of farmland irrigation diversion device, through its structure including a flow chamber, partition plate, inlet, through hole, filter plate, cover plate, valve, baffle, sliding strip, and limiting block, achieves efficient purification, uniform diversion, and precise control of irrigation water flow. The filter plate intercepts debris to ensure unobstructed flow; the flow chamber and partition plate, through a graded chamber design, achieve orderly dispersion of water flow; the inlet and through hole balance pressure to ensure uniform diversion; the valve, baffle, and other components work together to adjust the flow rate to adapt to different needs; the cover plate provides protection for the internal structure; and the sliding strip and limiting block enhance the stability and safety of control. The overall structure requires no complex power source, is easy to operate, and has a low failure rate. It improves water resource utilization, reduces maintenance costs, and can stably adapt to diverse farmland irrigation scenarios, providing reliable support for efficient agricultural production.

[0022] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0023] Please see Figure 1-5In this embodiment of the utility model, a farmland irrigation diversion device includes: a diverter 1, a baffle 2 fixedly installed on the upper end of the diverter 1, a valve 3 rotatably connected to the rear end of the diverter 1, an inlet 101 opened on the front of the diverter 1, an outlet pipe 102 fixedly installed on the rear end of the diverter 1, an outlet 103 opened at the rear end of the outlet pipe 102, the valve 3 being rotatably threadedly connected to the upper end of the outlet pipe 102, and a flow chamber 104 opened inside the diverter 1. The flow chamber 104 is composed of a first inlet chamber 105, a second inlet chamber 106, and a third inlet chamber 107. The first inlet chamber 105 is a single chamber and is located at the rear end of the inlet 101. The second inlet chamber 106 is located at the rear end of the first inlet chamber 105 and is a double chamber. The third inlet chamber 107 is located at... At the rear end of the second inlet chamber 106, which is a four-chamber configuration, a partition plate 108 is fixedly installed at equal intervals inside the flow chamber 104. The partition plate 108 divides the flow chamber 104 into a first inlet chamber 105, a second inlet chamber 106, and a third inlet chamber 107. A partition plate 110 is fixedly installed at equal intervals inside both the second inlet chamber 106 and the third inlet chamber 107. A through hole 111 is opened on the partition plate 110 inside the third inlet chamber 107. A water outlet 109 is opened at the rear end of both the partition plate 108 and the flow chamber 104, and the number of water outlets 109 is the same as the number of chambers. A filter plate 112 is fixedly connected to the front of the inlet 101 by threads. Irrigation water enters the device from the inlet 101 and first passes through the threaded connection on the front of the inlet. The filter plate 112 intercepts large particles of debris such as silt and weeds in the water, preventing blockage of subsequent chambers or through-holes and protecting the internal structure of the device. The filtered water flows into the flow chamber 104 inside the diverter 1 through the inlet 101, first entering the first inlet chamber 105. The first inlet chamber 105 serves as an initial buffer chamber, stabilizing the concentrated water flow and preparing for subsequent diversion. The water in the first inlet chamber 105 flows into the second inlet chamber 106 at the rear end through the through-hole 109 on the partition plate 108. Since the second inlet chamber 106 is a dual-chamber setup, divided into two independent sub-chambers by the internal partition plate 110, the water flow entering the second inlet chamber 106 is divided from a single stream into two streams. Water flows into the third inlet chamber 107 through the water outlet 109 on the rear partition plate 108. The third inlet chamber 107 is a four-chamber configuration, divided into four independent sub-chambers by the internal partition plate 110, achieving a second diversion from two streams to four streams. At this time, each sub-chamber in the third inlet chamber 107 corresponds to one stream of water, and the partition plate 110 in the sub-chamber has through holes 111 to balance the water pressure in each sub-chamber, ensuring that the flow rate of the four streams is initially uniform. The four streams of water in the third inlet chamber 107 flow through the water outlet 109 at the rear end of the flow chamber 104, with the number matching the four chambers of the third inlet chamber 107, i.e., four, and converge into the outlet pipe 102. The valve 3 rotatably connected to the upper end of the outlet pipe 102 can be rotated to adjust the opening. When the valve 3 is tightened...The internal passage of the outlet pipe 102 is compressed, reducing the water flow cross-section and decreasing the outflow volume. When valve 3 is loosened, the passage opens, allowing water to flow smoothly. Finally, the water, regulated by the valve, flows out from the outlet 103 at the rear end of the outlet pipe 102 and enters the subsequent branch pipes to complete the irrigation of the specific farmland area.

[0024] In this embodiment of the utility model, fixing plates 201 are fixedly installed at both ends of the enclosure 2. A cover plate 202 is connected to the inside of the enclosure 2 via hinges. A handle 203 is fixedly installed on one side of the upper end of the cover plate 202. A locking plate 204 is snapped between the fixing plates 201. A bolt 205 is threadedly connected to the middle of the upper end of the locking plate 204. The bolt 205 passes through the locking plate 204 and is threadedly connected to the cover plate 202. The cover plate 202 is connected to the inside of the enclosure 2 via hinges. When closed, it can completely cover the upper end of the diverter 1, forming a closed space to prevent rainwater, dust, and debris from falling into the flow chamber 104 of the diverter 1, thus preventing problems such as blockage and corrosion. At this time, the locking plate 204 is snapped into the enclosure 2. Between the fixing plates 201 on both the left and right ends, and with bolts 205 passing through the clamping plate 204 and threadedly connected to the cover plate 202, the cover plate 202 can be firmly fixed by tightening the bolts 205 to ensure a stable closed state. When it is necessary to inspect the inside of the flow chamber 104, rotate the bolts 205 to separate it from the cover plate 202, release the clamping plate 204 from the cover plate 202, remove the clamping plate 204 from between the fixing plates 201, grasp the handle 203 at the upper end of the cover plate 202, flip the cover plate 202 upwards, and use the flexibility of the hinge connection to open the internal space of the enclosure 2, exposing the upper area of ​​the diverter 1, which is convenient for operators to carry out internal maintenance, cleaning and other work.

[0025] In this embodiment of the utility model, a screw 301 is fixedly connected to the bottom of the valve 3, and a threaded sleeve 302 is threadedly connected to the surface of the screw 301. The threaded sleeve 302 is fixedly installed inside the upper end of the water outlet pipe 102. A baffle 303 is fixedly connected to the bottom of the screw 301, and a bearing 304 is embedded in the middle of the upper end of the baffle 303. The bearing 304 is rotatably connected to the bottom of the screw 301 without a threaded section. Sliding strips 305 are fixedly installed at both ends of the baffle 303, and the sliding strips 305 are slidably connected to the inside of the water outlet pipe 102. Limit blocks 306 are fixedly installed at both ends of the sliding strips 305. The inside of the water outlet pipe 102 is divided into upper and lower cavities, and the baffle 303 slides up and down between the two cavities. When it is necessary to adjust the water flow, the operator rotates the valve 3, and the screw 301 fixed at the bottom of the valve 3 rotates synchronously with it. The surface of the screw 301 and the threaded sleeve 302 fixedly installed inside the upper end of the water outlet pipe 102 form a threaded engagement. The threaded sleeve 302 remains stationary, while the screw 301 moves axially along the threaded sleeve 302 during rotation. The bottom of the screw 301 is connected to the baffle 303 via a bearing 304, and the bearing 304 only engages with the smooth, unthreaded section at the bottom of the screw 301. This ensures that the baffle 303 does not rotate with the screw 301, but is only driven up and down by the axial force of the screw. The sliding strips 305 at both ends of the baffle 303 are slidably connected to the inner wall of the outlet pipe 102, restricting the movement of the baffle. The direction of movement of 303 is to avoid deviation. When the screw 301 drives the baffle 303 to move downward, the baffle 303 gradually blocks the channel between the two cavities, reducing the cross-section of the water flow and reducing the water output. When the screw 301 drives the baffle 303 to move upward, the opening area of ​​the channel increases and the water output increases. If the baffle 303 completely closes the channel, the water flow can be completely cut off. The limiting blocks 306 at the upper and lower ends of the slide bar 305 can prevent the baffle 303 from rising and falling excessively.

[0026] Working principle: Irrigation water flows into the device from the inlet 101 on the front of the diverter 1. The water first passes through the filter plate 112, which is threaded on the front of the inlet 101. The filter plate intercepts large particles of debris such as mud and weeds in the water, preventing blockage of subsequent chambers or through holes and protecting the internal structure of the device. The filtered water enters the flow chamber 104 inside the diverter 1, and first enters the first inlet chamber 105. This chamber serves as an initial buffer space, stabilizing the concentrated water flow and preparing for subsequent diversion. The water in the first inlet chamber 105 flows into the second inlet chamber 106 at the rear through the outlet 109 on the front partition plate 108. The second inlet chamber 106 is a dual-chamber design, divided into two independent sub-chambers by the internal partition plate 110. The water flows from a single... The water flow is divided into two streams, completing the first diversion. The two streams of water in the second inlet chamber 106 flow into the third inlet chamber 107 through the water outlet 109 on the intermediate partition plate 108. The third inlet chamber 107 is a four-chamber configuration, divided into four independent sub-chambers by the internal partition plate 110. Here, the water flow is divided from two streams into four streams, completing the second diversion. At the same time, the partition plate 110 in the third inlet chamber 107 has a through hole 111 to balance the water flow pressure in the four sub-chambers and ensure that the flow rate of the four streams is initially uniform. The four streams of water in the third inlet chamber 107 converge into the outlet pipe 102 at the rear end of the diverter 1 through the water outlet 109 at the rear end of the flow chamber 104. The operator controls the water flow by rotating the valve 3. When the valve 3 is rotated, the screw fixed at the bottom... The screw 301 rotates synchronously, forming a threaded engagement with the threaded sleeve 302 fixed at the upper end of the outlet pipe 102, causing the screw 301 to move up and down axially. The bottom of the screw 301 is connected to the baffle 303 via a bearing 304, which ensures that the baffle does not rotate with the screw, but only slides up and down under axial force. The slide bars 305 at both ends of the baffle 303 are slidably connected to the inner wall of the outlet pipe 102, restricting its vertical movement and preventing deviation. When the baffle 303 moves downward, it gradually blocks the channel between the upper and lower cavities of the outlet pipe, reducing the water flow cross-section and decreasing the water output. When the baffle moves upward, the opening area of ​​the channel increases, increasing the water output. When completely closed, it can cut off the water flow. The limit blocks 306 at the upper and lower ends of the slide bars 305 prevent the baffle from rising and falling excessively, protecting the structure of the device. After being regulated by valve 3, the water flows out from the outlet 103 at the rear end of the outlet pipe 102 and enters the subsequent branch pipe to complete the irrigation of specific farmland areas. The enclosure 2 at the upper end of the diverter 1 forms a closed space through the closed cover plate 202 to prevent rainwater and dust from falling into the flow chamber 104 or valve 3. At this time, the clamping plate 204 is clamped between the fixing plates 201 on the left and right sides of the enclosure. The bolt 205 passes through the clamping plate and is threadedly connected to the cover plate to ensure that the cover plate is firmly fixed. When it is necessary to inspect the inside of the flow chamber 104, rotate the bolt 205 to separate it from the cover plate 202 and remove the clamping plate 204; hold the handle 203 at the upper end of the cover plate and flip the cover plate upward to expose the upper area of ​​the diverter for easy operation. After maintenance is completed, reverse the operation to reset and restore the closed protection state.
