[0002] With the continuous advancement of agricultural technology, intelligent irrigation technology is being applied more and more widely in modern agriculture. Valves are indispensable in intelligent agricultural irrigation systems, especially in some remote areas with large farmland areas where there are many valves. Manually opening and closing these valves is labor-intensive. Currently, solenoid valves are mostly used, but their disadvantages include significant pressure loss in long-distance pipelines, high power consumption when opening and closing the valves, and inconvenient access to electricity in farmland.

[0003] In the field of wireless control of intelligent electric valves, due to the need for a long-term power supply and the high requirement for low power consumption, how to ensure a good power supply for valve opening and closing is a crucial issue. In order to ensure normal power supply, solar panels are usually installed on the intelligent electric valves to generate electricity using solar energy. However, intelligent electric valves that use solar panels to generate electricity cannot generate electricity without sunlight, which leads to the problem of unreliable power supply.

[0004] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content

[0041] Please refer to Figures 1 to 6 As shown, it illustrates the specific structure of the pipeline water flow power generation device provided in the embodiment of this utility model. It is mainly used on electric valves, but is not limited to applications on electric valves, and can also be applied to other water flow pipelines.

[0042] The pipeline water flow power generation device includes a pipe body 10 for connection to a pipeline; a fixed impeller 20 and a moving impeller 30 are sequentially arranged inside the pipe body 10 along its axial direction. The fixed impeller 20 is fixedly installed on the inner wall of the pipe body 10, and the moving impeller 30 is rotatably connected to one end of the fixed impeller 20. An annular magnet 40 extending in the circumferential direction of the moving impeller 30 is arranged inside the outer peripheral sidewall of the moving impeller 30. A coil is arranged inside the inner peripheral sidewall of the pipe body 10 corresponding to the annular magnet 40, and the coil surrounds the outer periphery of the moving impeller 30. The coil lead 50 extends out of the tube 10. Here, when the water flows through the fixed impeller 20, the water flow direction rotates and tilts, causing the moving impeller 30 to obtain a large torque and drive the annular magnet 40 to rotate. The coil obtains an electromotive force, thus realizing water flow power generation. In this way, when applied to intelligent electric valves, power can be generated through water flow to supply power to the control box on the intelligent electric valve, without the need for solar panels. This solves the problem that existing intelligent electric valves that use solar panels cannot generate power in the absence of sunlight, making it difficult to guarantee power supply.

[0043] The outer peripheral wall of one end of the pipe body 10 is provided with a first external thread 61 for connection with a pipe, thus enabling a convenient detachable connection with the pipe via a threaded connection. A connecting pipe 60 for connection with the pipe is detachably connected to one end of the pipe body 10, and the first external thread 61 is formed on the outer peripheral wall of the connecting pipe 60 at the end away from the pipe body 10. In this embodiment, the outer peripheral wall of the pipe body 10 near the connecting pipe 60 is provided with a second external thread 11, and the inner peripheral wall of the connecting pipe 60 near the pipe body 10 is provided with a second internal thread 62. The second external thread 11 and the second internal thread 62 are threadedly connected to achieve a detachable threaded connection.

[0044] A first annular limiting step 12 is provided on the outer peripheral sidewall of the tube body 10 on the side of the second external thread 11 away from the connecting pipe 60. The first annular limiting step 12 extends along the circumferential direction of the tube body 10. The end face of the connecting pipe 60 near the tube body 10 abuts against the first annular limiting step 12. A second annular limiting step 63 is provided on the side of the second internal thread 62 away from the tube body 10 inside the end of the connecting pipe 60 near the tube body 10. The second annular limiting step 63 extends along the circumferential direction of the connecting pipe 60. The end face of the tube body 10 near the connecting pipe 60 abuts against the second annular limiting step 63. In this way, through the combined design of the first annular limiting step 12 and the second annular limiting step 63, mutual limiting in the axial direction between the tube body 10 and the connecting pipe 60 can be achieved.

[0045] A rotating shaft 21 is integrally protruding from the middle of one end of the fixed impeller 20. The rotating shaft 21 extends along the axial direction of the tube body 10. A connecting shaft portion 31 is provided in the middle of the moving impeller 30. The connecting shaft portion 31 extends along the axial direction of the tube body 10. The connecting shaft portion 31 is provided with a rotating hole 32. The rotating shaft 21 is connected to the rotating hole 32. A positioning frame 64 is provided inside the connecting tube 60. A positioning platform 65 is protruding from the middle of the positioning frame 64. The positioning platform 65 abuts against the end of the connecting shaft portion 31 away from the fixed impeller 20. Furthermore, a circular boss 22 is integrally protruded from the middle of one end of the fixed impeller 20, and the rotating shaft 21 is integrally protruded from the surface of the boss 22 away from the fixed impeller 20. The end of the connecting shaft 31 near the fixed impeller 20 abuts against the boss 22. Thus, the rotating impeller 30 can be rotated through the combination design of the rotating shaft 21, the connecting shaft 31 and the rotating hole 32, and the axial direction of the moving impeller 30 can be limited through the combination design of the positioning table 65 and the boss 22.

[0046] In this embodiment, the positioning frame 64 has a Y-shaped structure and includes three connecting sides. One end of each of the three connecting sides is integrally connected to the outer peripheral sidewall of the positioning platform 65, and the other end of each of the three connecting sides is integrally connected to the inner peripheral sidewall of the connecting pipe 60.

[0047] An annular spacer wall 13 is provided in the opening at one end of the tube body 10. One end of the annular spacer wall 13 is connected to the outer peripheral wall of the fixed impeller 20. An annular relief groove 14 extending in the circumferential direction of the tube body 10 is recessed on the end face of one end of the tube body 10. The annular relief groove 14 is located around the annular spacer wall 13, and the coil is located inside the annular relief groove 14. The opening of the annular relief groove 14 is sealed by the second annular limiting step 63. Furthermore, the opening of the annular relief groove 14 can be sealed with glue first, and then sealed by the second annular limiting step 63. This can improve the sealing performance of the coil inside. The annular spacer wall 13 surrounds the outer periphery of the moving impeller 30, and the distance between the inner peripheral sidewall of the annular spacer wall 13 and the outer peripheral sidewall of the moving impeller 30 is set.

[0048] In this embodiment, the coil includes several coil arrays 70, which are arranged at uniform intervals along the circumferential direction of the tube 10 in the annular relief groove 14. Several winding posts 15 are protruding from the outer peripheral sidewall of the annular spacer 13, and the winding posts 15 are arranged at uniform intervals along the circumferential direction of the annular spacer 13. The coil arrays 70 are wound on the corresponding winding posts 15. During manufacturing, the annular spacer 13 with several winding posts 15 can be formed first, and then the several coil arrays 70 can be wound on the several winding posts 15 respectively. Then, the annular spacer 13 can be embedded into the outer peripheral wall of the fixed impeller 20 by insert injection molding process to achieve the purpose of integrated structure, which is more conducive to the sealing and isolation of the coil.

[0049] The outer peripheral sidewall of the moving impeller 30 is recessed with an annular positioning groove 33 at one end face away from the fixed impeller 20. The annular positioning groove 33 extends along the circumferential direction of the moving impeller 30. The annular magnet 40 is positioned in the annular positioning groove 33. After the annular magnet 40 is installed in the annular positioning groove 33, the opening of the annular positioning groove 33 is sealed with glue.

[0050] like Figures 7 to 9 As shown, it illustrates the specific structure of applying the pipeline water flow power generation device to an electric valve. The electric valve is a T-type three-way ball valve 80. The lead wire 50 of the coil of the pipeline water flow power generation device is connected to the control box of the electric valve. The inner circumferential side wall of the inlet 82 of the valve body 81 of the T-type three-way ball valve 80 is provided with a first internal thread 83, and the first external thread 61 is threadedly connected to the first internal thread 83.

[0051] In summary, the key design feature of this invention lies in the sequential arrangement of a fixed impeller and a moving impeller along the axial direction of the pipe body. The fixed impeller is fixedly mounted on the inner wall of the pipe body, while the moving impeller is rotatably connected to one end of the fixed impeller. A ring magnet is placed inside the outer circumferential sidewall of the moving impeller, and a coil is placed inside the inner circumferential sidewall of the pipe body corresponding to the ring magnet. The coil's lead extends outside the pipe body. Thus, when water flows through the fixed impeller, the water flow direction rotates and tilts, causing the moving impeller to obtain a large torque and drive the ring magnet to rotate. The coil then obtains an electromotive force, thereby realizing water-flow power generation. When applied to an intelligent electric valve, this invention can generate electricity through water flow to power the control box on the intelligent electric valve, eliminating the need for solar panels. This solves the problem of existing intelligent electric valves that use solar panels to generate electricity but cannot guarantee power supply in the absence of sunlight.

Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
