Description

Technical Field

[0001] This utility model relates to water conservancy and irrigation technology, specifically to a water conservancy and irrigation diversion device suitable for mountainous areas. Background Technology

[0002] Water conservancy irrigation refers to the artificial control of water use, which involves drawing surface water or groundwater through engineering measures, transporting it to the root zones of crops such as farmland, forest land, and grassland through a water distribution system, and replenishing soil moisture in a timely and appropriate manner according to the water requirements of crops to meet the water conditions needed for normal plant growth and development. It encompasses water source projects (reservoirs, ponds, dams, pumping stations, wells, etc.), water distribution networks (canals, pipelines, tunnels, aqueducts, etc.), field irrigation facilities (sprinkler irrigation, drip irrigation, micro-sprinkler irrigation, seepage irrigation, furrow irrigation, etc.), and corresponding water quantity regulation, water quality monitoring, and management systems. By regulating water quantity, water pressure, water temperature, water quality, and irrigation time, it aims to achieve water conservation and efficiency improvement, drought resistance and harvest protection, soil improvement, prevention of salinization and soil erosion, and enhancement of comprehensive agricultural production capacity. At the same time, it also takes into account the water needs of the ecological environment. It is a comprehensive technical system that intersects multiple fields such as modern agriculture, water conservancy, and ecology, and plays an irreplaceable and fundamental role in ensuring food security, promoting sustainable rural economic development, and maintaining regional water balance.

[0003] Currently, slope irrigation in mountainous areas commonly employs a main pipe-branch pipe structure, where rigid or flexible branch pipes are connected to the main pipe at intervals to distribute irrigation water to different slope locations. However, the existing branch pipes have fixed inner diameters and lack flow regulation mechanisms, resulting in essentially uniform outlet flow rates across all branch pipes, making it impossible to differentiate water distribution based on slope elevation differences. In actual operation, after irrigation from the branch pipes at higher elevations, the water flows downhill under gravity, causing the soil at lower elevations to receive a double volume of water from both its own branch pipes and the higher-level confluence. This leads to excessive infiltration and even erosion at lower elevations, while higher elevations may still experience water shortages. This "same flow rate" diversion method is highly susceptible to soil erosion, fertilizer loss, and crop waterlogging or drought in mountainous areas with significant slope variations, severely impacting irrigation uniformity and agricultural efficiency in mountainous regions. Therefore, improvements to the existing technology are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a water diversion device suitable for irrigation in mountainous areas, in order to solve the problems in the existing technology where the outlet flow of the diversion branch pipe is fixed and cannot be adjusted according to the difference in slope elevation, resulting in an imbalance in water distribution between high and low slopes, excessive saturation and erosion on low slopes while high slopes are still short of water.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water diversion device for irrigation in mountainous areas, comprising:

[0006] The main pipeline is laid along the mountain slope to introduce irrigation water.

[0007] Branching seats are installed at intervals on the main pipe;

[0008] Diverter pipes, a plurality of such diverter pipes being connected to diverter seats;

[0009] The diversion pipe has a cavity pipe at one end, an irrigation pipe at the upper end of the cavity pipe, and a number of spray heads connected to the outer wall of the irrigation pipe along its axial direction. The inner wall of the upper end of the irrigation pipe has a number of internal threads, and an adjusting rod is screwed into the irrigation pipe through the internal threads. The outer wall of the adjusting rod has external threads, and a sealing rod is fixedly connected to the lower end of the adjusting rod. When the adjusting rod rotates and drives the sealing rod to move, it gradually seals the water inlet holes at the inner ends of the spray heads along the axial direction of the irrigation pipe for flow regulation.

[0010] Furthermore, a rotating handle is fixedly connected to the upper end of the adjusting rod.

[0011] Furthermore, a sealing head is fixedly connected to the lower end of the sealing rod. The sealing head has a disc-shaped structure, and the outer wall of the sealing head is interference-fitted with the inner wall of the irrigation pipe.

[0012] Furthermore, the sealing head is made of silicone material.

[0013] Furthermore, it also includes a fixing component disposed at the lower end of the cavity tube, the fixing component including a support plate seat fixedly disposed at the lower end of the cavity tube.

[0014] Furthermore, a through hole is provided in the upper wall of the support plate, and an insertion rod is inserted into the through hole. A pressing plate is fixedly connected to the upper end of the insertion rod.

[0015] Compared with existing technologies, the water diversion device for irrigation in mountainous areas provided by this utility model can move axially up and down within the irrigation pipe by rotating the adjusting rod, thereby causing the sealing rod to sequentially block different numbers of water inlet holes at the inner end of the sprinkler heads, thus changing the number of open sprinkler heads and the flow area. Reducing the number of open sprinkler heads at higher slopes can reduce the flow rate, while maintaining or increasing the number of open sprinkler heads at lower slopes can obtain a relatively larger flow rate, offsetting the influence of gravity confluence. This achieves differentiated water distribution in mountainous areas, with "less irrigation at higher slopes and more irrigation at lower slopes," avoiding excessive saturation and erosion of lower slopes due to the combined water volume of "its own branch pipes + confluence at higher slopes," while ensuring the water needs of crops at higher slopes, thus improving irrigation uniformity and soil and water conservation effects.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] As attached Figure 1 To be continued Figure 3 As shown:

[0024] Example 1:

[0025] This utility model provides a water diversion device for irrigation in mountainous areas, comprising:

[0026] Main pipe 1 is laid along the mountain slope to introduce irrigation water.

[0027] Diverter 2 is installed at intervals on the main pipe 1;

[0028] Diversion pipe 3, a plurality of the diversion pipes 3 are connected to the diversion seat 2;

[0029] The diversion pipe 3 is connected to a cavity pipe 4 at one end, and an irrigation pipe 5 is connected to the upper end of the cavity pipe 4. Several spray heads 6 are connected to the outer wall of the irrigation pipe 5 along its axial direction. Several internal threads are provided on the inner wall of the upper end of the irrigation pipe 5. An adjusting rod 7 is screwed into the inside of the irrigation pipe 5 through the internal threads. An external thread is provided on the outer wall of the adjusting rod 7. A sealing rod 8 is fixedly connected to the lower end of the adjusting rod 7. When the adjusting rod 7 rotates and drives the sealing rod 8 to move, it gradually seals the water inlet holes of the several spray heads 6 provided along the axial direction of the irrigation pipe 5, which is used for flow regulation.

[0030] As can be seen from the above, by rotating the adjusting rod 7, it can be moved up and down along the axis inside the irrigation pipe 5, which drives the sealing rod 8 to block the water inlet holes at the inner end of different numbers of sprinkler heads 6 in sequence, thereby changing the number of open sprinkler heads 6 and the flow area. Reducing the number of open sprinkler heads at higher slopes can reduce the flow rate, while maintaining or increasing the number of open sprinkler heads at lower slopes can obtain a relatively large flow rate, offsetting the influence of gravity confluence, realizing differentiated water distribution in mountainous areas with "less irrigation at higher slopes and more irrigation at lower slopes", avoiding excessive soaking and scouring of lower slopes due to the double water volume of "its own branch pipes + confluence at higher slopes", while ensuring the water needs of crops at higher slopes, improving irrigation uniformity and soil and water conservation effects.

[0031] As attached Figure 3 As shown, specifically, the upper end of the adjusting rod 7 is fixedly connected to a rotating handle 9, and the outer wall of the rotating handle 9 is provided with anti-slip texture.

[0032] As can be seen from the above, by rotating the rotating handle 9, the operator can move the adjusting rod 7, so that the adjusting rod 7 can be quickly turned in the field without tools, realizing "on-site and instant" flow adjustment, which meets the needs of mountainous areas with scattered plots and varying slopes, and improves adjustment efficiency and convenience.

[0033] Example 2:

[0034] This utility model provides a water diversion device for irrigation in mountainous areas, comprising:

[0035] Main pipe 1 is laid along the mountain slope to introduce irrigation water.

[0036] Diverter 2 is installed at intervals on the main pipe 1;

[0037] Diversion pipe 3, a plurality of the diversion pipes 3 are connected to the diversion seat 2;

[0038] The diversion pipe 3 is connected to a cavity pipe 4 at one end, and an irrigation pipe 5 is connected to the upper end of the cavity pipe 4. Several spray heads 6 are connected to the outer wall of the irrigation pipe 5 along its axial direction. Several internal threads are provided on the inner wall of the upper end of the irrigation pipe 5. An adjusting rod 7 is screwed into the inside of the irrigation pipe 5 through the internal threads. An external thread is provided on the outer wall of the adjusting rod 7. A sealing rod 8 is fixedly connected to the lower end of the adjusting rod 7. When the adjusting rod 7 rotates and drives the sealing rod 8 to move, it gradually seals the water inlet holes of the several spray heads 6 provided along the axial direction of the irrigation pipe 5, which is used for flow regulation.

[0039] This embodiment is basically the same as the previous embodiment, except that, as shown in the appendix... Figure 3 As shown, to further improve the sealing connection, a sealing head 10 is fixedly connected to the lower end of the sealing rod 8. The sealing head 10 has a disc-shaped structure, and the outer wall of the sealing head 10 is interference-fitted with the inner wall of the irrigation pipe 5.

[0040] The sealing head 10 is made of silicone material.

[0041] As can be seen from the above, the silicone disc-shaped sealing head 10 forms an interference seal with the inner wall of the irrigation pipe 5, which can completely seal the gap water flow and achieve water flow without leakage; at the same time, the elasticity of silicone compensates for manufacturing errors, prevents mud and sand from getting stuck, and ensures that a reliable seal is maintained after long-term repeated adjustments, avoiding water accumulation and erosion at low places caused by dripping.

[0042] Example 3:

[0043] This utility model provides a water diversion device for irrigation in mountainous areas, comprising:

[0044] Main pipe 1 is laid along the mountain slope to introduce irrigation water.

[0045] Diverter 2 is installed at intervals on the main pipe 1;

[0046] Diversion pipe 3, a plurality of the diversion pipes 3 are connected to the diversion seat 2;

[0047] The diversion pipe 3 is connected to a cavity pipe 4 at one end, and an irrigation pipe 5 is connected to the upper end of the cavity pipe 4. Several spray heads 6 are connected to the outer wall of the irrigation pipe 5 along its axial direction. Several internal threads are provided on the inner wall of the upper end of the irrigation pipe 5. An adjusting rod 7 is screwed into the inside of the irrigation pipe 5 through the internal threads. An external thread is provided on the outer wall of the adjusting rod 7. A sealing rod 8 is fixedly connected to the lower end of the adjusting rod 7. When the adjusting rod 7 rotates and drives the sealing rod 8 to move, it gradually seals the water inlet holes of the several spray heads 6 provided along the axial direction of the irrigation pipe 5, which is used for flow regulation.

[0048] This embodiment is basically the same as the previous embodiment, except that, as shown in the appendix... Figure 2 As shown, in order to facilitate the stable fixing of components such as the cavity tube 4 to the slope, a fixing assembly is also included at the lower end of the cavity tube 4. The fixing assembly includes a support plate seat 11 fixedly disposed at the lower end of the cavity tube 4.

[0049] The upper wall of the support plate 11 has a through hole, and an insertion rod 12 is inserted into the through hole. A pressing plate 13 is fixedly connected to the upper end of the insertion rod 12.

[0050] As can be seen from the above, during installation, simply pass the insertion rod 12 through the through hole of the support plate 11 and press down the pressing plate 13 to nail the insertion rod 12 directly into the slope soil, forming an integrated "nail-plate" anchor. The support plate 11 increases the contact area with the slope, disperses the water flow back force and gravity, prevents the irrigation pipe 5 from swinging or sliding down during spraying, ensures that the spray head 6 always faces the crop area, maintains a stable irrigation angle and range, and adapts to the soft and steep foundation conditions in mountainous areas.

[0051] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
