Description

Technical Field

[0001] This utility model relates to the field of irrigation devices, specifically a solar-powered water-saving irrigation device for farmland. Background Technology

[0002] Solar-powered water pumps for farmland irrigation primarily utilize solar photovoltaic power generation systems to convert solar energy into electrical energy, which then drives the water pumps to irrigate the farmland. Solar panels generate direct current (DC) under sunlight, converting solar energy into electrical energy. These panels are typically installed in open, sunny locations, such as vacant land near farmland or on rooftops. The generated DC power is usually stored in batteries to power the water pumps during periods of insufficient sunlight or at night. Simultaneously, an inverter converts the DC power to alternating current (AC) to power the AC-driven water pump, depending on the pump's needs. For DC-driven pumps, the power can be directly obtained from the batteries. Driven by this electricity, the water pumps draw water from sources (such as rivers, wells, or ponds) and delivers it to the farmland through an irrigation pipeline system, thus irrigating the crops.

[0003] Irrigation pipeline systems can include main pipes, branch pipes, and sprinklers, and are rationally arranged according to different irrigation methods (such as sprinkler irrigation, drip irrigation, and spring irrigation) to ensure that water can be evenly distributed to all areas of the farmland. However, laying irrigation pipes directly in the farmland can cause mechanical damage to the pipes due to frequent agricultural activities such as tilling, fertilizing, and harvesting. Agricultural machinery may also crush or tear the pipes during field operations, leading to leaks, affecting irrigation efficiency, and increasing maintenance costs. Furthermore, laying irrigation pipes directly in the farmland can easily damage newly sprouted seedlings. Utility Model Content

[0004] The purpose of this invention is to provide a solar-powered water-saving irrigation device for farmland, in order to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, a solar-powered water-saving irrigation device for farmland is provided, comprising a water-saving irrigation cylinder A, with a connecting flange fixedly installed at the end of the water-saving irrigation cylinder A, and a water-saving irrigation cylinder B fixedly installed on the water-saving irrigation cylinder A through the connecting flange. Fixing seats are provided on the outer circumferential walls of the ends of both the water-saving irrigation cylinder B and the water-saving irrigation cylinder A. Support columns are screwed to the bottom of both sets of fixing seats, and wheels are installed at the bottom of both sets of support columns. An outer cylinder is provided on the water-saving irrigation cylinder A, a middle cylinder is movably installed inside the outer cylinder, and an inner cylinder is movably installed inside the middle cylinder.

[0006] Furthermore, the water-saving irrigation cylinder A and the water-saving irrigation cylinder B have the same structure. They are connected by a connecting flange, and the bottoms of both are supported by support columns and wheels.

[0007] Furthermore, both the water-saving irrigation cylinder A and the water-saving irrigation cylinder B are telescopic structures. The water-saving irrigation cylinder A includes an inlet hose, an outer cylinder, a first limiting plate, a middle cylinder, a second limiting plate, an inner cylinder, a first sealing seat, a second sealing seat, an outer atomizing nozzle, a middle atomizing nozzle, and an inner atomizing nozzle. Both the water-saving irrigation cylinder A and the water-saving irrigation cylinder B are equipped with inlet hoses at their ends. The inlet hoses are connected to the outlet pipe of an external water source booster pump, which is powered by a solar cell.

[0008] Furthermore, an outer atomizing nozzle is fixedly installed at the end of the outer cylinder, a middle atomizing nozzle is fixedly installed at the end of the middle cylinder, and an inner atomizing nozzle is fixedly installed at the end of the inner cylinder. The axial cross-sections of the outer cylinder, middle cylinder, and inner cylinder are concentric circles.

[0009] Furthermore, a first limiting piece is fixedly installed on the inner circumference of the outer cylinder, and a second limiting piece is fixedly installed on the inner circumference of the middle cylinder. The depth of the inner cylinder inserted into the middle cylinder is limited by the second limiting piece, and the depth of the middle cylinder inserted into the outer cylinder is limited by the first limiting piece. Handles are installed at the ends of both the water-saving irrigation cylinder A and the water-saving irrigation cylinder B.

[0010] Furthermore, the bottom of each set of support columns is equipped with a connecting pipe and a sleeve respectively through a fixed flange. The dimensions of the connecting pipe and the sleeve are compatible, and the connecting pipe is inserted into the inside of the sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model reduces the overall volume of the irrigation cylinder by retracting the outer, middle, and inner cylinders when not in use, making it easier to store and transport. This is very important for irrigation equipment that needs to be moved or stored frequently, as it can save storage space, reduce transportation costs, and facilitate the transfer and installation of the equipment in different farmland areas. It is also suitable for fields of different widths.

[0013] 2. In this utility model, the bottoms of both the water-saving irrigation cylinder A and the water-saving irrigation cylinder B are supported by support columns and wheels. The wheels allow the irrigation cylinders to move easily on the field ridges, making it convenient to flexibly adjust the irrigation position according to the water needs of crops in different areas of the farmland. Since crops are generally not planted on the field ridges, the wheels will not directly affect the root growth of crops, which helps to maintain the looseness and permeability of the soil, maintain the ecological environment of the farmland, and avoid damage to newly sprouted seedlings.

[0020] Please see Figure 1-5 This utility model provides a solar-driven water-saving irrigation device for farmland, including a water-saving irrigation cylinder A1. A connecting flange 2 is fixedly installed at the end of the water-saving irrigation cylinder A1. A water-saving irrigation cylinder B3 is fixedly installed on the water-saving irrigation cylinder A1 through the connecting flange 2. Fixing seats 5 are provided on the outer circumferential walls of the ends of both the water-saving irrigation cylinder B3 and the water-saving irrigation cylinder A1. Support columns 6 are screwed to the bottom of both sets of fixing seats 5. Wheels 7 are installed at the bottom of both sets of support columns 6. An outer cylinder 11 is provided on the water-saving irrigation cylinder A1. A middle cylinder 13 is movably installed inside the outer cylinder 11. An inner cylinder 15 is movably installed inside the middle cylinder 13.

[0021] Working principle: In actual use, water-saving irrigation cylinders B3 and A1 are respectively set up above the fields to be irrigated. Two people hold the handles 4 at the ends of water-saving irrigation cylinders B3 and A1 respectively. At this time, water flows from the two sets of inlet hoses 100 into the interior of water-saving irrigation cylinders A1 and B3 respectively, and is sprayed out from the outer atomizing nozzle 18, the middle atomizing nozzle 19, and the inner atomizing nozzle 20 to complete the irrigation of the field plants. Water-saving irrigation cylinders A1 and B3 are mainly composed of three parts: outer cylinder 11, middle cylinder 13, and inner cylinder 15. The irrigation system is composed of an outer cylinder 11, a middle cylinder 13, and an inner cylinder 15, which employ a telescopic structure. This telescopic structure allows for changes in the overall height and lateral dimensions of the irrigation cylinder, thereby flexibly adjusting the distribution range of the outer atomizing nozzles 18 and the middle atomizing nozzles 19. When crop planting densities differ or when specific areas require targeted irrigation, the telescopic structure can be used to adjust the nozzles to appropriate positions, achieving precise irrigation, improving water resource utilization efficiency, and avoiding water waste. When not in use, the outer cylinder 11, middle cylinder 13, and inner cylinder 15 can be retracted to reduce the overall volume of the irrigation cylinder, facilitating storage and transportation. This is crucial for irrigation equipment that requires frequent movement or storage, saving storage space, reducing transportation costs, and facilitating the transfer and installation of equipment in different farmland areas. It also adapts to fields of varying widths. Both the water-saving irrigation cylinders A1 and B3 are supported at their bases by support columns 6 and wheels 7. The wheels 7 allow the irrigation cylinders to move easily along field paths, enabling flexible adjustments to the irrigation position based on the water needs of crops in different areas of the farmland, achieving precise irrigation. Compared to fixed irrigation facilities, movable irrigation cylinders better adapt to different crop layouts in farmland. The changes in planting patterns allow for the rapid movement of irrigation cylinders to areas requiring irrigation, reducing the time and labor costs associated with laying and dismantling fixed irrigation pipes, thereby improving irrigation efficiency and enabling the irrigation of large areas of farmland to be completed in a shorter time. Compared to traditional irrigation equipment that is set up and travels in the field, the wheels 7 move on the field ridges, reducing the compaction and damage to the farmland soil. Since crops are generally not planted on the field ridges, the wheels traveling on them will not directly affect the root growth of crops, which helps to maintain the looseness and permeability of the soil, protect the ecological environment of the farmland, and avoid damage to plants.

[0022] As a preferred embodiment, the water-saving irrigation cylinder A1 and the water-saving irrigation cylinder B3 have the same structure. The water-saving irrigation cylinder A1 and the water-saving irrigation cylinder B3 are connected by a connecting flange 2.

The ends of both the water-saving irrigation cylinder A1 and the water-saving irrigation cylinder B3 are equipped with inlet hoses 100, which are connected to the outlet pipe of an external water source booster pump. The booster pump is powered by a solar cell.

[0025] In a preferred embodiment, a first limiting piece 12 is fixedly installed on the inner circumference of the outer cylinder 11, and a second limiting piece 14 is fixedly installed on the inner circumference of the middle cylinder 13. The depth of the inner cylinder 15 inserted into the middle cylinder 13 is limited by the second limiting piece 14, and the depth of the middle cylinder 13 inserted into the outer cylinder 11 is limited by the first limiting piece 12. Handles 4 are installed at the ends of both the water-saving irrigation cylinder A1 and the water-saving irrigation cylinder B3.

[0026] In a preferred embodiment, the bottom of each of the two sets of support columns 6 is respectively equipped with a connecting pipe 9 and a sleeve 10 via a fixing flange 8. The dimensions of the connecting pipe 9 and the sleeve 10 are compatible, and the connecting pipe 9 is inserted into the inside of the sleeve 10.
