Description

Technical Field

[0001] This utility model relates to the field of farmland irrigation technology. More specifically, this utility model relates to a farmland irrigation water conveyance pipeline. Background Technology

[0002] Farmland irrigation is essential for ensuring a bumper harvest. Traditional irrigation methods involve high-water-level canals for flooding, which wastes water resources and easily leads to uneven irrigation. Newer methods, such as sprinkler or drip irrigation, suffer from lower water pressure due to the direct contact between the water pipe outlet and the soil. This can cause siltation and blockages, and the irrigation range is limited, making them unsuitable for irrigating fruits and vegetables or for long-distance, large-scale operations. Utility model patent CN210905206U discloses an anti-clogging connector for farmland irrigation pipes. It uses a tapered pipe with gradually decreasing diameter to create a pressure chamber, facilitating rapid distribution of irrigation water within the guiding chamber. However, while accelerating water flow, it limits the overall flow rate, making it unsuitable for multi-branch, long-distance, large-scale operations. Summary of the Invention

[0003] This utility model provides a farmland irrigation water supply pipeline, which can pressurize the water flow in the secondary water supply pipeline and deliver irrigation water to the farmland through multiple water supply nozzles, thereby carrying out long-distance and large-scale irrigation operations.

[0004] To achieve these objectives and other advantages according to the present invention, an agricultural irrigation water conveyance pipeline is provided, comprising:

[0005] The main water pipeline is connected to the water source at one end and closed at the other end.

[0006] Multiple secondary water supply pipes are provided. One end of each secondary water supply pipe is connected to the main water supply pipe, and the other end is closed. The secondary water supply pipes are arranged alternately on the main water supply pipe. A pressure-boosting outer pipe and multiple water supply nozzles are installed sequentially on each secondary water supply pipe along the water flow direction. The pressure-boosting outer pipe has a liquid storage cavity. The secondary water supply pipes are connected to the liquid storage cavity of the pressure-boosting outer pipe. The multiple water supply nozzles are spaced apart on the secondary water supply pipes.

[0007] Preferably, a pair of booster pipes are connected in parallel on the secondary water supply pipe.

[0008] Preferably, a pair of booster pipes are installed on a pair of first pipe segments via tees, and the two ends of the pair of first pipe segments are connected to four second pipe segments via bends, and the four second pipe segments are connected to the water supply auxiliary pipe via tees.

[0009] Preferably, the secondary water supply pipe is provided with multiple water inlets, and each water inlet is provided with a water supply nozzle, which includes an umbrella-shaped water supply rod, and a circumferential water supply gap is formed between the water inlet and the umbrella-shaped water supply rod.

[0010] Preferably, the secondary water supply pipe is equipped with multiple water supply nozzles via multiple tees. Each water supply nozzle includes a straight water supply rod and a pair of curved water supply rods. One end of the pair of curved water supply rods is installed on the straight water supply rod via a tee, and the other end is closed but has a water outlet.

[0011] Preferably, the lower end of the straight tubular water conveying rod is fixedly connected to a tee connecting the lower water conveying secondary pipe, and the upper end of the straight tubular water conveying rod is rotatably connected to a tee connecting a pair of curved tubular water conveying rods above.

[0012] This utility model has at least the following beneficial effects:

[0013] First, the main water supply pipeline of this utility model is connected to the water source and delivers irrigation water to various secondary water supply pipelines. The secondary water supply pipelines are equipped with pressure boosting outer pipes to realize the pressure boosting, acceleration and surging of irrigation water in the branch bypass. The secondary water supply pipelines are also equipped with multiple water supply nozzles, so that the irrigation water from the secondary water supply pipelines can cover deep into the farmland, realizing long-distance and large-scale irrigation operations.

[0014] Secondly, the main water supply pipeline and the secondary water supply pipeline are connected by a tee to form a bypass pipeline. The joint is sealed with sealing tape or a sealing component to achieve a sealed installation. The connection method is preferably detachable, such as a threaded connection, to facilitate assembly and transportation. The secondary water supply pipelines are arranged alternately on the left and right sides of the main water supply pipeline, which facilitates the dispersed placement of the secondary water supply pipelines in farmland and allows for long-distance and large-scale coverage of the operation area. Depending on the actual terrain, only the secondary water supply pipeline on that side can be installed. The booster pipe is set above the secondary water supply pipeline, preferably through a tee to form an upward-opening pipeline. Irrigation water is used to backflow the booster pipe to pressurize the secondary water supply pipeline. Multiple water supply nozzles are preferably set at equal intervals. They can be used in the form of drip irrigation or in the form of sprinkler irrigation after the nozzles are opened, to further improve the water spraying effect.

[0015] Third, there is a pair of external pressure boosting pipes, which are connected in parallel to the secondary water supply pipe to further improve the pressure boosting effect and accelerate the flow of irrigation water. Specifically, by setting up a first pipe segment and a second pipe segment, a pair of external pressure boosting pipes are connected and installed. Tees and bends together form a U-shaped structure, which facilitates the orderly installation of components in the field.

[0016] Fourth, compared to simply setting up a water inlet, adding water delivery nozzles can change the direction of irrigation water flow. An umbrella-shaped water delivery rod is vertically positioned at the inlet, sealed at the bottom and with a certain circumferential gap at the waist. The umbrella-shaped rod forms a limiting surface along its axial direction, allowing water to spray radially from the circumferential gaps, creating a circumferential spray range. A pair of curved water delivery rods are connected to a straight water delivery rod via a tee. The straight water delivery rods guide the flow upwards, while the pair of curved water delivery rods guide the flow horizontally, expanding the spray range. Furthermore, the lower end of the straight water delivery rod is fixed, while its upper end is rotatably connected to the tee connecting the pair of curved water delivery rods above. This can be achieved through bearing connections, sleeve connections, or other means, allowing the pair of curved water delivery rods to rotate relative to the straight water delivery rods. The impact of the irrigation water flow pushes the pair of curved water delivery rods to rotate, thus expanding and increasing the spray range through a rotating, sling-spraying motion.

[0017] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0026] like Figures 1-3 As shown, this utility model provides a farmland irrigation water conveyance pipeline, comprising:

[0027] The main water supply pipeline 1 is connected to the water source at one end and closed at the other end.

[0028] Multiple secondary water supply pipes 2 are provided. One end of each secondary water supply pipe 2 is connected to the main water supply pipe 1, and the other end is closed. Multiple secondary water supply pipes 2 are arranged alternately on the main water supply pipe 1. Each secondary water supply pipe 2 is equipped with a pressure boosting outer pipe 3 and multiple water supply nozzles 4 along the water flow direction. The pressure boosting outer pipe 3 has a liquid storage cavity. The secondary water supply pipe 2 is connected to the liquid storage cavity of the pressure boosting outer pipe 3. Multiple water supply nozzles 4 are arranged at intervals on the secondary water supply pipe 2.

[0029] In the above technical solution, the main water supply pipeline 1 is connected to the water source and delivers irrigation water to each secondary water supply pipeline 2. The secondary water supply pipeline 2 is equipped with a pressure boosting outer pipe 3 to realize the pressure boosting, acceleration and surging of irrigation water in the branch bypass. The secondary water supply pipeline 2 is also equipped with multiple water supply nozzles 4, so that the irrigation water of the secondary water supply pipeline 2 can cover the depths of the farmland, realizing long-distance and large-scale irrigation operations.

[0030] The main water supply pipeline 1 and the secondary water supply pipeline 2 are connected by a tee to form a bypass pipeline. The joint is sealed with sealing tape or a sealing component to achieve a sealed installation. The connection method is preferably detachable, such as a threaded connection, for easy assembly and transportation. The secondary water supply pipeline 2 is arranged alternately on the left and right sides of the main water supply pipeline 1, which facilitates the dispersed placement of the secondary water supply pipeline 2 in farmland and allows for long-distance and large-scale coverage of the operation area. Depending on the actual terrain, only the secondary water supply pipeline 2 on that side can be installed. The booster pipe 3 is set above the secondary water supply pipeline 2, preferably through a tee to form an upward-opening pipeline. The booster pipe 3 can be an inverted cylinder, which simplifies the structure without simplifying the function compared to existing pumps and other mechanical structures. Irrigation water is used to backflow the booster pipe 3 to pressurize the irrigation water in the secondary water supply pipeline 2. Multiple water supply nozzles 4 are preferably set at equal intervals, which can be in the form of drip irrigation or sprinkler irrigation with a structure after opening, to further improve the water spraying effect.

[0031] like Figure 2 As shown, in another technical solution, a pair of pressure-boosting outer pipes 3 are connected in parallel to the secondary water supply pipe 2. The number of pressure-boosting outer pipes 3 is one pair, connected in parallel to the secondary water supply pipe 2 to further improve the pressure boosting effect and accelerate the flow of irrigation water.

[0032] like Figure 2 As shown, in another technical solution, a pair of booster pipes 3 are respectively installed on a pair of first pipe segments via tees. The two ends of the pair of first pipe segments are respectively connected to four second pipe segments via bends. The four second pipe segments are connected to the water supply auxiliary pipe 2 via tees. Specifically, by setting up first pipe segments and second pipe segments, a pair of booster pipes 3 are connected and installed. The tees and bends together form a U-shaped structure, which facilitates the orderly installation of components in the field.

[0033] like Figure 4 As shown, in another technical solution, the secondary water supply pipe 2 is provided with multiple water inlets, and each water inlet is equipped with a water supply nozzle 4, which includes an umbrella-shaped water supply rod 5. A circumferential water supply gap is formed between the water inlet and the umbrella-shaped water supply rod 5. Compared with only setting water inlets, the water supply nozzle 4 can change the direction of irrigation water flow. The umbrella-shaped water supply rod 5 is vertically set at the water inlet, that is, the bottom is sealed and fixed to the secondary water supply pipe 2, the waist forms a certain circumferential interval with the water inlet, and the top forms a radially extending surface. The umbrella-shaped water supply rod 5 forms an obstruction restricting the flow of irrigation water in the axial direction, so that the water is sprayed radially from the circumferential water supply gap, forming a circumferential spray range.

[0034] like Figure 5As shown, in another technical solution, multiple water delivery nozzles 4 are installed on the secondary water delivery pipe 2 via multiple tees. Each water delivery nozzle 4 includes a straight water delivery rod 6 and a pair of curved water delivery rods 7. One end of the pair of curved water delivery rods 7 is installed on the straight water delivery rod 6 via a tee, and the other end is closed but has an outlet. Compared to simply setting a water inlet, setting water delivery nozzles 4 can change the direction of irrigation water flow. By connecting the pair of curved water delivery rods 7 and the straight water delivery rod 6 via tees, the straight water delivery rod 6 guides the flow upwards, while the pair of curved water delivery rods 7 guide the flow horizontally. Figure 5 To show the structure of a pair of curved water delivery rods 7 from a medium-angle perspective (in reality, the pair of curved water delivery rods 7 should be located on the same horizontal plane), the spraying range is expanded.

[0035] In another technical solution, the lower end of the straight tubular water conveying rod 6 is fixedly connected to a tee connecting to the lower water conveying secondary pipe 2, and the upper end of the straight tubular water conveying rod 6 is rotatably connected to a tee connecting to a pair of curved tubular water conveying rods 7. Furthermore, the lower end of the straight tubular water conveying rod 6 is fixed, and the upper end is rotatably connected to the tee connecting to the pair of curved tubular water conveying rods 7. This can be achieved through bearing connections, sleeve connections, or other means, allowing the pair of curved tubular water conveying rods 7 to rotate relative to the straight tubular water conveying rod 6. Under the impact of the irrigation water flow, the pair of curved tubular water conveying rods 7 are pushed to rotate, thereby expanding and widening the spraying range through a rotating and spraying motion.

[0036] The number of devices and processing scale described herein are for the purpose of simplifying the description of this utility model. Applications, modifications, and variations of this utility model will be readily apparent to those skilled in the art.

[0037] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
