Description

Technical Field

[0001] This utility model relates to the field of irrigation device technology, specifically an energy-saving farmland irrigation device. Background Technology

[0002] In agricultural production, farmland irrigation is a crucial link in ensuring crop growth and increasing agricultural output. Traditional farmland irrigation devices are mostly simple in structure and have many problems.

[0003] In common water storage containers, liquids typically require a stirring structure for mixing during storage. However, the interaction between the liquids is slow, resulting in low mixing efficiency. This leads to a large number of undissolved water and fertilizer particles in the liquid, causing uneven mixing, which affects irrigation effectiveness and may also clog pipes, hindering irrigation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an energy-saving farmland irrigation device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An energy-saving farmland irrigation device includes:

[0007] A liquid storage tank is provided with a liquid extraction pipe at its bottom, and the inlet end of the liquid extraction pipe is attached to the bottom wall of the liquid storage tank.

[0008] The first arc-shaped guide is fixed to the inner wall of the liquid storage tank and located on one side of the liquid extraction pipe. Its outer wall curved surface is arranged tangentially to the suction direction of the liquid extraction pipe.

[0009] The water pump is connected to the storage tank via a liquid extraction pipe, and a three-way valve is connected to the water outlet.

[0010] The return pipe is connected to one outlet end of the three-way valve and extends to the top of the inside of the storage tank;

[0011] The second arc-shaped guide is fixed at the outlet end of the return pipe and spaced apart from the inner wall of the storage tank. Its outer curved surface is tangential to the discharge direction of the return pipe. The second arc-shaped guide and the first arc-shaped guide are staggered in the vertical direction to form an alternating swirling flow field.

[0012] Preferably, the ratio of the radius of curvature of the first arc-shaped guide to the radius of curvature of the second arc-shaped guide is 1.2-1.5:1.

[0013] Preferably, the vertical distance between the lowest point of the first arc-shaped guide and the highest point of the second arc-shaped guide is 1 / 8 to 1 / 6 of the height of the liquid storage tank.

[0014] Preferably, the angle between the guiding surface of the first arc-shaped guide and the horizontal plane is 15°-30°.

[0015] Preferably, the bottom of the storage tank has a conical structure, and the conical bottom wall is provided with an annular guide groove surrounding the liquid extraction pipe.

[0016] Preferably, the inclination angle of the conical bottom wall is 10°-15°, and the annular guide groove is provided with spiral stirring ribs.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. During liquid circulation and mixing, the return pipe returns the pressurized liquid to the top of the storage tank, which enables better exchange and circulation between the liquid at the bottom and the liquid at the top, further mixing the liquid and preventing sedimentation.

[0019] 2. Improve liquid extraction efficiency and uniformity:

[0020] The inlet end of the liquid extraction pipe is attached to the bottom wall of the liquid storage tank, and works in conjunction with the bottom conical structure and annular guide groove to efficiently draw out the liquid and provide a stable liquid source for the water pump.

[0021] The first arc-shaped guide guides the liquid to form a swirling flow in a specific direction, promoting the mixing and flow of the liquid and improving the efficiency and uniformity of liquid extraction.

[0022] It forms a stable and efficient swirling field, improving mixing and flowability:

[0023] The ratio of the curvature radius of the first arc-shaped guide to that of the second arc-shaped guide is 1.2-1.5:1. A reasonable ratio of curvature radii helps to form a stable and efficient swirling flow field.

[0024] The two are arranged alternately in the vertical direction to form an alternating swirling flow field, which can create strong convection in the liquid storage tank, greatly improving the mixing effect and fluidity of the liquid.

[0025] The structure of the swirling flow field is optimized to allow the liquid to circulate and mix fully: the vertical distance between the lowest point of the first arc-shaped guide and the highest point of the second arc-shaped guide is 1 / 8 to 1 / 6 of the height of the storage tank. This precise distance setting further optimizes the structure of the swirling flow field, allowing the liquid to circulate and mix fully in the storage tank.

[0026] Increasing the dissolved oxygen content in liquids is beneficial to crop growth: Liquid circulation can increase the dissolved oxygen content in liquids to a certain extent, which is beneficial to crop growth. Attached Figure Description

[0033] Example

[0034] like Figure 1-3 As shown, an energy-saving farmland irrigation device includes:

[0035] Storage tank 1: This is the core water storage component of the entire irrigation system. Its bottom is designed with a conical structure, and the inclination angle of the conical bottom wall is 10°-15°. This special conical structure allows the liquid to naturally converge to the bottom under the action of gravity, facilitating extraction. The conical bottom wall also has an annular guide groove surrounding the extraction pipe 2. The spiral stirring ribs set in the annular guide groove can effectively prevent impurities in the liquid from settling, ensuring uniform mixing of the liquid and providing good conditions for subsequent extraction and irrigation.

[0036] Liquid extraction pipe 2: The inlet end of liquid extraction pipe 2 is attached to the bottom wall of liquid storage tank 1, which can extract the liquid in the storage tank to the maximum extent and reduce residue. It works in conjunction with the conical structure and annular guide groove at the bottom of liquid storage tank 1 to efficiently draw out the liquid and provide a stable liquid source for water pump 4.

[0037] The first arc-shaped guide 3 is fixed to the inner wall of the liquid storage tank 1 and located on one side of the liquid extraction pipe 2. Its outer curved surface is tangential to the suction direction of the liquid extraction pipe 2. When the water pump 4 extracts liquid, the first arc-shaped guide 3 guides the liquid to flow in a specific direction, causing the liquid to swirl within the storage tank, promoting mixing and flow, and improving the efficiency and uniformity of liquid extraction. The angle between the guiding surface of the first arc-shaped guide 3 and the horizontal plane is 15°-30°. This angle setting optimizes the liquid flow trajectory and enhances the swirling effect. Furthermore, the radius of curvature of the first arc-shaped guide 3 plays a crucial role in the fluid dynamics design of the entire device. Its ratio to the radius of curvature of the second arc-shaped guide 7 is 1.2-1.5:1. A reasonable ratio of radius of curvature helps to form a stable and efficient swirling field.

[0038] Water pump 4 is the power core of the entire irrigation device. It is connected to the storage tank 1 through the liquid extraction pipe 2 and is responsible for extracting and pressurizing the liquid in the storage tank 1 to provide power for liquid transportation. Its outlet is connected to a three-way valve 5, which can control the flow direction of the liquid.

[0039] Three-way valve 5: The three-way valve 5 is connected to the outlet end of the water pump 4. By adjusting the three-way valve 5, the flow direction of the liquid can be controlled, realizing the switching between irrigation and liquid return functions. When farmland irrigation is required, the liquid can be directed to the irrigation pipeline; when the liquid in the storage tank needs to be circulated and mixed, the liquid can be returned to the storage tank 1 through the return pipe 6.

[0040] Return pipe 6: The return pipe 6 connects to one outlet end of the three-way valve 5 and extends to the top of the inside of the storage tank 1. Its function is to return the liquid pressurized by the water pump 4 back to the storage tank 1, realizing the circulation and mixing of the liquid, and allowing for better exchange and circulation between the liquid at the bottom and top of the storage tank 1. Through liquid circulation, the liquid in the storage tank can be further mixed, preventing sedimentation, and at the same time, increasing the dissolved oxygen content of the liquid to a certain extent, which is beneficial to the growth of crops.

[0041] The second arc-shaped guide 7 is fixed to the outlet end of the return pipe 6 and spaced apart from the inner wall of the storage tank 1. Its outer curved surface is tangential to the discharge direction of the return pipe 6. When liquid is discharged from the return pipe 6, the second arc-shaped guide 7 guides the liquid to form a swirling flow in the opposite direction to the first arc-shaped guide 3. The second arc-shaped guide 7 and the first arc-shaped guide 3 are staggered in the vertical direction to form an alternating swirling flow field. This alternating swirling flow field can create strong convection within the storage tank, greatly improving the mixing effect and fluidity of the liquid. The guiding surface of the second arc-shaped guide 7 has an angle of 15°-30° with the horizontal plane, and its radius of curvature maintains a ratio of 1.2-1.5:1 to the first arc-shaped guide 3, ensuring the stability and efficiency of the swirling flow field. The vertical distance between the lowest point of the first arc-shaped guide 3 and the highest point of the second arc-shaped guide 7 is 1 / 8 to 1 / 6 of the height of the liquid storage tank. This precise spacing setting further optimizes the structure of the swirling flow field, allowing the liquid to circulate and mix fully within the liquid storage tank.

[0042] The storage tank 1 serves as the core of the water storage system. Its conical bottom structure allows the liquid to naturally converge towards the bottom under gravity. This, combined with the annular guide channel surrounding the extraction pipe 2 and the spiral stirring ribs, prevents impurities from settling and ensures uniform mixing of the liquid. The inlet end of the extraction pipe 2 is fitted to the bottom wall of the storage tank 1, working in conjunction with the bottom structure and the annular guide channel to efficiently extract the liquid.

[0043] After the water pump 4 starts, it draws liquid from the storage tank 1 through the suction pipe 2. At this time, the first arc-shaped guide 3 fixed to the inner wall of the storage tank 1 plays a role. Its outer curved surface is tangent to the suction direction of the suction pipe 2, and the angle between the guide surface and the horizontal plane is 15°-30°. The specific radius of curvature makes the liquid form a swirling flow in a specific direction in the storage tank 1, which promotes liquid mixing and flow and improves the extraction efficiency and uniformity.

[0044] Pump 4 pressurizes the extracted liquid and delivers it to three-way valve 5. Three-way valve 5 acts as a control hub, adjusting the liquid flow direction according to actual needs. When farmland irrigation is required, three-way valve 5 directs the liquid to the irrigation pipeline to irrigate the farmland; when the liquid in storage tank 1 needs to be circulated and mixed, three-way valve 5 introduces the liquid into return pipe 6.

[0045] The return pipe 6 returns the pressurized liquid, pumped by the water pump 4, to the top of the storage tank 1. A second arc-shaped guide 7, connected to the outlet of the return pipe 6, has an outer curved surface tangent to the discharge direction of the return pipe 6. The guide surface forms an angle of 15°-30° with the horizontal plane, maintaining a specific ratio to the radius of curvature of the first arc-shaped guide 3. When the liquid is discharged from the return pipe 6, the second arc-shaped guide 7 guides the liquid to form a swirling flow in the opposite direction to that of the first arc-shaped guide 3. Because the two are staggered vertically, an alternating swirling flow field is formed within the storage tank 1, generating strong convection, achieving liquid exchange and circulation between the bottom and top, further mixing the liquid, preventing sedimentation, and increasing the dissolved oxygen content, which is beneficial for crop growth.

[0046] Easy to extract liquid: The bottom of the liquid storage tank 1 has a conical structure, and the liquid naturally converges to the bottom under the action of gravity, making it easy to extract.

[0047] To prevent impurities from settling and ensure the liquid is mixed evenly:

[0048] Spiral stirring ribs are installed in the annular guide groove of the conical bottom wall, which can effectively prevent impurities in the liquid from settling and ensure uniform mixing of the liquid.

[0049] During liquid circulation and mixing, the return pipe 6 returns the pressurized liquid to the top of the storage tank 1, which enables better exchange and circulation between the bottom liquid and the top liquid, further mixing the liquid and preventing sedimentation.

[0050] Improve liquid extraction efficiency and uniformity:

[0051] The inlet end of the liquid extraction pipe 2 is attached to the bottom wall of the liquid storage tank 1, and works in conjunction with the bottom conical structure and annular guide groove to efficiently draw out the liquid and provide a stable liquid source for the water pump 4.

[0052] The first arc-shaped guide 3 guides the liquid to form a swirling flow in a specific direction, promoting the mixing and flow of the liquid and improving the efficiency and uniformity of liquid extraction.

[0053] It forms a stable and efficient swirling field, improving mixing and flowability:

[0054] The ratio of the curvature radius of the first arc-shaped guide 3 to that of the second arc-shaped guide 7 is 1.2-1.5:1. A reasonable ratio of curvature radii helps to form a stable and efficient swirling flow field.

[0055] The two are arranged alternately in the vertical direction to form an alternating swirling flow field, which can create strong convection in the liquid storage tank 1, greatly improving the mixing effect and fluidity of the liquid.

[0056] The structure of the swirling flow field is optimized to ensure sufficient circulation and mixing of the liquid: the vertical distance between the lowest point of the first arc-shaped guide and the highest point of the second arc-shaped guide is 1 / 8 to 1 / 6 of the height of the liquid storage tank 1. This precise spacing setting further optimizes the structure of the swirling flow field, enabling the liquid to circulate and mix fully within the liquid storage tank 1.

[0057] Increasing the dissolved oxygen content in liquids is beneficial to crop growth: Liquid circulation can increase the dissolved oxygen content in liquids to a certain extent, which is beneficial to crop growth.

[0058] To achieve functional switching and meet different needs: the three-way valve 5 can control the flow direction of the liquid, realize the function switching of irrigation or liquid return, and meet the needs of different usage scenarios.

[0059] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
