Description

Technical Field

[0001] This invention relates to the field of coconut cultivation technology, specifically to a water pipe irrigation system for large-scale cultivation of Hainan high-yield coconuts. Background Technology

[0002] Coconut trees are common landscaping trees in Hainan, but to achieve higher yields, stronger trees, earlier fruiting, reduced labor costs, and large-scale cultivation, facility-based cultivation is essential. Hainan's soil is mostly sandy, with relatively concentrated rainfall during the rainy season. However, from planting to the full recovery stage, coconut seedlings need to be watered twice a day to maintain humidity, facilitating seedling recovery and management. Coconuts are generally planted during the dry season, with temperatures reaching up to 40 degrees Celsius and prolonged periods without rain, requiring timely maintenance of humidity and proper transplanting during the recovery stage.

[0003] A search revealed a patent with application number CN202023115816.9, which discloses a water-saving irrigation device for coconut cultivation. This device can collect rainwater and use it for irrigation, while preventing water from evaporating and saving water resources. It can also automatically irrigate, eliminating the need for manual irrigation and reducing the labor intensity of growers.

[0004] The aforementioned device overlooks many practical problems in the irrigation process, such as silt entering the water tank with rainwater and wind, accumulating at the bottom of the tank and gradually clogging the pipes, and lacking measures for removing sand from the pipes. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a water pipe irrigation system for large-scale cultivation of high-yield coconuts in Hainan, which solves the technical problem that existing coconut irrigation systems lack measures for removing sand from the pipes, causing sand to easily accumulate and gradually clog the irrigation pipes.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A water pipe irrigation system for large-scale cultivation of high-yield coconuts in Hainan includes a water pump, and the water pump is connected to a sand-discharging irrigation component; The sand-draining irrigation assembly includes multiple regional main pipelines set at different heights, with at least one regional main pipeline set at the same height. The coverage area of ​​each regional main pipeline does not exceed 25 mu. Adjacent regional main pipelines are connected by bend pipes. A sand-draining pipe is set every other regional main pipeline. The sand-draining pipe is connected to the regional main pipeline. A filter is connected to the water pump inlet. A second valve is installed on the sand-draining pipe.

[0007] Furthermore, a tee pipe is connected to the main pipeline in the area, and a vent valve is connected to one end of the tee pipe.

[0008] Furthermore, the vent valve includes a front vent valve near the water pump and a rear vent valve away from the water pump. The front vent valve is 50m away from the water pump, and the rear vent valve is located more than 100m away from the water pump. At least two vent valves are installed within 200m of the water pump on the main pipeline in the area. The vent valves are spaced 80m apart when they are more than 300m away from the water pump, and the rear vent valves are spaced 70m apart.

[0009] Furthermore, a machine room is provided at one end of the main pipeline in the area, where the water pump and filter are located. The machine room is equipped with a frequency converter control cabinet that is electrically connected to the water pump and filter.

[0010] Furthermore, a branch pipe is connected to the side of the main pipeline in the area, and a spray pipe is connected to the top of the branch pipe. The spray pipe is a PE pipe, and a first valve is connected between the branch pipe and the main pipeline in the area.

[0011] Furthermore, the diameter of the main pipeline in the area is 160mm, the diameter of the spray pipe is 20mm-25mm, the thickness of the spray pipe is 1.3mm-1.5mm, and the nominal pressure of the spray pipe exceeds 0.25bar.

[0012] Furthermore, the top of the spray pipe is fixedly connected to multiple inclined rods, and the top of the inclined rods is provided with caps. The caps are rotatably connected to one of the inclined rods. During the seedling stage and within one year of planting, the roots are sprayed in a directional manner after the caps are covered with bags.

[0013] Furthermore, the nominal pressure when the distance between the main pipeline and the water pump in the area is less than 200m is PN1, and the nominal pressure when the distance between the main pipeline and the water pump in the area is greater than 200m is PN2. PN1 and PN2 satisfy the following relationship: PN1 > 10 bar, PN2 > 6 bar.

[0014] By employing the above technical solution, the present invention provides a water pipe irrigation system for large-scale cultivation of high-yield coconuts in Hainan, which has at least the following beneficial effects: 1. This invention filters the sediment in the irrigation water before it enters the pipe by setting up a filter and a sand discharge pipe, thereby reducing the amount of sediment entering the pipe. At the same time, it flushes the sediment in the pipe at fixed intervals, using water flow to remove the sediment from the pipe, reducing the sediment deposited in the pipe. This increases the measures for removing sediment from the pipe, which can reduce the amount of sediment entering the pipe, and at the same time, the water flow washes away the sediment deposited in the pipe, preventing the sediment from remaining in the irrigation pipe and gradually clogging the pipe.

[0015] 2. This invention, through the installation of spray pipes and caps, can adjust the spraying method at different growth stages of coconut trees, meeting the water needs of the roots and branches at different growth stages, and ensuring the humidity requirements of coconut trees in regions including western Hainan.

[0016] 3. The present invention, through the setting of the variable frequency power cabinet, can ensure that the water pressure of each area of ​​the water pump and the water supply of each tree are basically the same, and ensure that the growth of each tree is basically the same.

[0017] 4. In the event of a sudden start-up of the water supply system without opening the regional water gates for water spraying, the frequency conversion system will also shut down in time, preventing the main water pipe from bursting or the water pump from being damaged.

[0020] 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.

[0021] Example 1 To remove silt from the irrigation pipes and prevent it from clogging them, please refer to... Figures 1-3This embodiment proposes a water pipe irrigation system for large-scale cultivation of high-yield coconuts in Hainan, including a water pump 1. A sand-discharging irrigation component 2 is connected to the water pump 1. The sand-discharging irrigation component 2 includes multiple regional main pipes 21 installed at different heights, with at least one regional main pipe 21 installed at the same height. The coverage area of ​​each regional main pipe 21 does not exceed 25 mu (approximately 1 hectare). Adjacent regional main pipes 21 are connected by a bend pipe 22. A sand-discharging pipe 23 is installed every other regional main pipe 21 and is connected to the regional main pipe 21. A filter 24 is connected to the water inlet of the water pump 1, and a second valve is installed on the sand-discharging pipe 23. 25. A machine room 5 is located at one end of the main regional pipeline 21. The water pump 1 and the filter 24 are both located in the machine room 5. The machine room 5 is equipped with a frequency converter control cabinet 6 that is electrically connected to the water pump 1 and the filter 24. A branch pipe 7 is connected to the side of the main regional pipeline 21. A spray pipe 8 is connected to the top of the branch pipe 7. The spray pipe 8 is a PE pipe. A first valve 9 is connected between the branch pipe 7 and the main regional pipeline 21. The diameter of the main regional pipeline 21 is 160mm. The diameter of the spray pipe 8 is 20mm-25mm. The thickness of the spray pipe 8 is 1.3mm-1.5mm. The nominal pressure of the spray pipe 8 exceeds 0.25bar.

[0022] The variable frequency power cabinet ensures that the water pump has no regional water supply pressure and that the water volume for each tree is basically the same. This ensures that the growth of each tree is basically the same. The sand discharge pipe 23 is discharged twice a month for 10 minutes each time. The end of the sand discharge pipe 23 is cleaned manually in a timely manner, generally once every 15-25 days. After each cleaning, the water discharged from the sand discharge pipe 23 is clear and normal water supply can begin.

[0023] If the switch is forgotten to be turned on or the voltage is insufficient, the frequency converter control cabinet 6 will automatically cut off the power supply to protect water pump 1. In the event of a sudden activation of the water supply system without opening the area's water gates, the frequency converter system will also shut down promptly, preventing main water pipe bursts and pump damage. When planting coconut trees, ensure a single row of 14 trees (14 trees per acre), with a plant and row spacing of 7 meters. Each tree receives the same water volume. Water pump 1 requires 22.5KW, a head of 97 meters, and a flow rate of 97 cubic meters per hour. The main pipeline 21 is 160mm wide. The pressure requirement for the main pipeline within 150m of water pump 1 is 10 kg; within 200m of water pump 1, the pressure requirement is 8 kg; and beyond 200m of water pump 1, the pressure requirement is 6 kg. A vent valve 4 is installed within 50 meters of the water pump outlet on the main pipeline 21, connecting to the main pipeline 21. The vent valve 4 is perpendicular to the tee pipe 3. A vent valve 4 is then installed every 70 meters. The outlet of filter 24 can be appropriately equipped with a nail gun for application. Nails are used to reinforce the connection points. Within 150 meters of the water pump 1, the main pipeline 21 needs to use large and small connectors. The pipeline network adopts zoned water supply, with the same slope forming one area. Pipelines with different slopes are connected by bends 22. The pipeline network of each area is controlled by the first valve 9. A sand discharge outlet is set up for every 100 acres. The sand discharge outlet is a water pipe with a diameter of 50mm. Sand needs to be discharged more than twice a month, each time for 15-20 minutes. If the incoming water contains silt, the frequency is increased as needed. By combining the filter 24 and the sand discharge pipe 23, the silt in the water is filtered before the irrigation water enters the pipeline, reducing the amount of silt entering the pipeline. At the same time, the silt in the pipeline is flushed at fixed intervals. The silt in the pipeline is flushed away by the water flow from the sand discharge pipe 23, reducing the silt deposited in the pipeline. This increases the measures for sand discharge in the pipeline, which can reduce the amount of silt entering the pipeline. At the same time, the water flow flushes away the silt deposited in the pipeline, preventing the silt from staying in the irrigation pipeline and gradually clogging the pipeline.

[0024] Example 2 To improve the spraying effect on the coconut tree roots, and to adjust the spraying method according to different growth stages of the coconut trees, refer to... Figures 1-3Based on Example 1, a T-pipe 3 is connected to the main regional pipeline 21. One end of the T-pipe 3 is connected to a vent valve 4. The vent valve 4 includes a front vent valve near the water pump 1 and a rear vent valve away from the water pump 1. The distance between the front vent valve and the water pump 1 is 50m. The rear vent valve is located at a position more than 100m away from the water pump 1. At least two vent valves 4 are installed within 200m of the distance between the main regional pipeline 21 and the water pump 1. The distance between the vent valves 4 is 80m when the distance between the main regional pipeline 21 and the water pump 1 is more than 300m. The distance between the rear vent valves is 70m. Multiple inclined rods 10 are fixedly connected to the top of the spray pipe 8. The top of the inclined rod 10 is provided with a cap 11. The cap 11 is rotatably connected to one of the inclined rods 10. During the seedling recovery stage and within one year of planting, the roots are sprayed directionally after the cap is covered with a bag to facilitate the recovery of coconut seedlings and their rapid growth.

[0025] Considering that the internal water pressure is higher the closer the main pipeline 21 is to the water pump 1, pressure relief valves 4 are installed adaptively according to the water pressure characteristics at different locations of the main pipeline 21. Pressure relief valves 4 are installed at different distribution densities within 100m of the main pipeline 21, between 100m and 300m, and after 300m, so that different locations of the main pipeline 21 can withstand the internal water pressure and prevent the pipeline from rupturing due to excessive internal water pressure at locations close to the water pump 1.

[0026] When in use, the sprinkler pipe 8 is drilled with special equipment and then installed 0.5m-1m away from the coconut seedling. In the first year of the coconut tree’s growth, the cap 11 is rotated to cover the sprinkler pipe 8. At this time, the cap 11 is above the sprinkler pipe 8. The water flow sprayed from the sprinkler pipe 8 is blocked by the cap 11 and then falls to the roots of the coconut tree in a parabolic shape along the arc of the bottom of the cap 11, ensuring that the roots of the coconut tree are thoroughly watered.

[0027] In the first and second years of the coconut tree's growth, rotate the cap 11 to the side of the sprinkler pipe 8 so that the cap 11 no longer covers the opening of the sprinkler pipe 8, allowing the water sprayed from the sprinkler pipe 8 to spray onto the branches and leaves of the coconut tree.

[0028] Two years after the coconut tree has grown, the cap 11 is rotated again to cover the sprinkler pipe 8, so that the sprinkler pipe 8 sprays the roots of the coconut tree as it did in the first year. The purpose is to ensure the humidity of the coconut tree roots and ensure that the gourd-shaped head of the tall coconut tree will appear after two years.

[0029] By combining the above-mentioned different spraying methods for coconut trees at different stages, the spraying method can be adjusted at different growth stages of the coconut tree to meet the water needs of the roots and branches at different growth stages and ensure the humidity requirements of the coconut tree.
