However, this structure has the following problems:

[0003] 1. Impurities in the water can easily enter the generator, causing blockages, affecting power generation efficiency, and even damaging the generator;

[0004] 2. After long-term use, scale tends to accumulate on the generator blades and shaft, affecting power generation efficiency and increasing maintenance costs. Summary of the Invention

[0005] The purpose of this invention is to provide a cleanable hydroelectric power generation control box to solve at least the above-mentioned problems and to provide at least the advantages described below.

[0006] To achieve these objectives and other advantages according to the present invention, a cleanable hydroelectric power generation control box is provided, comprising:

[0007] The box body is equipped with a water inlet and a water outlet;

[0008] A solenoid valve is disposed inside the housing, and the water inlet of the housing is connected to the water inlet of the solenoid valve.

[0009] A miniature hydroelectric generator is installed inside the box, and the outlet of the box is connected to the outlet of the miniature hydroelectric generator.

[0010] The outlet of the solenoid valve and the inlet of the micro hydroelectric generator are connected by a chamber. The chamber has an installation hole, and a filter device is detachably installed in the installation hole. The filter device is located on the water flow path between the outlet of the solenoid valve and the inlet of the micro hydroelectric generator.

[0011] Preferably, the chamber includes a first chamber connected to the outlet of the solenoid valve, a second chamber connected to the inlet of the micro hydroelectric generator, and a third chamber connecting the first and second chambers. The mounting hole is opened in the third chamber, and the filter device is disposed in the third chamber.

[0012] Preferably, the filtration device includes a filter screen tube, a first connector connected to one end of the filter screen tube, and a second connector connected to the other end of the filter screen tube. The first connector abuts against the connection between the third chamber and the first chamber. The first connector is also provided with a water passage hole connecting the first chamber and the inside of the filter screen tube. The filter screen tube is located at the connection between the third chamber and the first chamber. The second connector is sealed and connected to the mounting hole.

[0013] Preferably, the end face of the first connector facing the first chamber has an annular groove coaxial with the water passage hole, a magnetizer is provided in the groove, and the groove opening is provided with a buckle for fixing the magnetizer.

[0014] Preferably, the micro hydroelectric generator includes a housing, an impeller, a shaft, and a generator coil. The impeller is mounted on the shaft, which is supported within the housing by bearings. The generator coil is mounted within the housing and positioned opposite to the shaft. The inlet and outlet of the micro hydroelectric generator are both located on the housing.

[0015] Preferably, the surfaces of the impeller and the shaft are provided with an anti-fouling coating.

[0016] Preferably, the anti-scaling coating is a polytetrafluoroethylene coating or a ceramic coating.

[0019] Preferably, the magnetizer is a permanent magnet or an electromagnet, and the magnetic field strength is 1000-3000 Gauss.

[0020] This invention offers at least the following beneficial effects: The filtration device plays a crucial role in the entire hydroelectric power generation system. As water flows from the outlet of the solenoid valve to the inlet of the micro hydroelectric generator, the filtration device effectively intercepts large particles of impurities in the water. If these impurities enter the micro hydroelectric generator, they can cause blockages, leading to reduced power generation efficiency or even damage. The filtration device prevents this from happening, ensuring the normal operation of the micro hydroelectric generator and maintaining stable power generation efficiency.

[0021] The filter is detachably mounted in the mounting holes of the chamber, a design that facilitates equipment maintenance. Over long-term use, the filter will trap a significant amount of impurities; when cleaning or replacement is needed, the filter can be simply disassembled. This greatly saves maintenance time and labor costs, improves equipment maintainability, and enables the hydroelectric control box to operate continuously and stably.

[0022] 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

[0027] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

Therefore, they should not be construed as limitations on this utility model.

[0029] like Figures 1-4 As shown, this utility model provides a cleanable hydroelectric power generation control box, comprising:

[0030] Box 1, which is provided with a water inlet and a water outlet;

[0031] Solenoid valve 4 is disposed inside the housing 1, and the water inlet 2 of the housing 1 is connected to the water inlet of the solenoid valve 4.

[0032] A miniature hydroelectric generator 5 is installed inside the housing 1, and the outlet 3 of the housing 1 is connected to the outlet of the miniature hydroelectric generator 5.

[0033] The outlet of the solenoid valve 4 and the inlet of the micro hydroelectric generator 5 are connected by a chamber. The chamber has an installation hole, and a filter device 6 is detachably installed in the installation hole. The filter device 6 is located on the water flow path between the outlet of the solenoid valve 4 and the inlet of the micro hydroelectric generator 5.

[0034] Specifically, the hydroelectric power generation control box may also include a circuit board 7 and a rechargeable lithium battery 8. The circuit board 7 is used for program control of the solenoid valve 4 switching and the charging circuit, and the rechargeable lithium battery 8 is used to store the electricity generated by the micro hydroelectric generator 5 and to supply power to the outside.

[0035] The solenoid valve 4 is a normally closed solenoid valve, which is normally closed when not in operation, and opens after receiving a signal from the circuit board 7 when powered on.

[0036] The operation of the hydroelectric power generation control box is as follows: After the solenoid valve 4 is opened, water flows into the inlet 2 of the box body 1. Passing through the solenoid valve 4, the water flows towards the filter device 6, where large particles of impurities are filtered out. The filtered water then enters the micro hydroelectric generator 5, which generates electricity. This electricity is stored in the rechargeable lithium battery 8, and the generated water flows out from the outlet 3 of the box body 1. By setting up the filter device 6, large particles of impurities in the water can be effectively filtered, preventing them from entering the generator and causing blockages.

[0037] Furthermore, the chamber includes a first chamber connected to the outlet of the solenoid valve 4, a second chamber connected to the inlet of the micro hydroelectric generator 5, and a third chamber connecting the first chamber and the second chamber. The mounting hole is opened in the third chamber, and the filter device 6 is disposed in the third chamber.

[0038] In this embodiment, the water flowing from the solenoid valve 4 first enters the first chamber, then is filtered by the filter device 6 in the third chamber, and finally flows into the second chamber to the micro hydroelectric generator 5. This layout ensures that the water is effectively filtered before entering the micro hydroelectric generator 5, preventing impurities from entering the generator. This chamber structure is clearly divided, facilitating the installation and maintenance of each component. Cleaning or replacing the filter device 6 is also more convenient due to its location in the independent third chamber.

[0039] Furthermore, the filter device 6 includes a filter screen tube 601, a first connector 602 connected to one end of the filter screen tube 601, and a second connector 603 connected to the other end of the filter screen tube 601. The first connector 602 abuts against the communication between the third chamber and the first chamber. The first connector 602 is also provided with a water passage hole 604 communicating between the first chamber and the interior of the filter screen tube 601. The filter screen tube 601 is located at the communication between the third chamber and the first chamber. The second connector 603 is sealed and connected to the mounting hole.

[0040] In this embodiment, the first connector 602 abuts against the connection between the third chamber and the first chamber, and the water passage 604 therein connects the first chamber and the interior of the filter screen 601, guiding the water flow into the filter screen 601 in an orderly manner for filtration. This ensures that the water flow is not turbulent when passing through this point, guaranteeing the stability and continuity of filtration and making the filtration process smoother.

[0041] The filter screen 601 is located at the connection between the third chamber and the first chamber, and its position is designed to directly filter the water flowing from the first chamber to the second chamber. Since the water flow must pass through this point, large particles of impurities are effectively intercepted outside the filter screen 601, preventing them from entering the micro hydroelectric generator 5. This ensures the normal operation of the generator and reduces the possibility of malfunctions caused by impurities entering.

[0042] The second connector 603 is sealed in the mounting hole, a design that ensures the stability and sealing of the entire filter device 6. The stable installation prevents the filter device 6 from easily loosening or shifting under water flow impact, thus affecting the filtration effect; the good sealing prevents unfiltered water from leaking from the mounting hole, ensuring that all water flows are filtered through the filter mesh 601, thereby improving the reliability of the filtration.

[0043] Furthermore, the end face of the first connector 602 facing the first chamber is provided with an annular groove coaxial with the water passage 604, a magnetizer 605 is provided in the groove, and the groove opening is provided with a buckle 606 for fixing the magnetizer 605.

[0044] In this embodiment, an annular groove coaxial with the water passage hole 604 is formed on the end face of the first connector 602 facing the first chamber. This design provides specific space for the installation of the magnetizer 605. The presence of the groove allows the magnetizer 605 to be precisely positioned, preventing it from swaying due to the impact of water flow, thus ensuring that the magnetizer 605 is always in the optimal working position and can stably perform its function.

[0045] The magnetizer 605 is placed in the settling tank. When water flows through the water passage 604, it passes through the magnetic field area generated by the magnetizer 605. The magnetic field of the magnetizer 605 can affect the minerals and other components in the water, causing changes in the structure of some substances in the water. This helps to reduce the formation of scale and lowers the possibility of scale depositing on the impeller and shaft of the micro hydroelectric generator 5, thereby ensuring the normal operation of the generator and maintaining its power generation efficiency.

[0046] The inverted clip 606 at the trough opening is used to secure the magnetizer 605, a design that further enhances the stability of the magnetizer 605's installation. During long-term use, even under continuous water flow, the magnetizer 605 remains firmly fixed within the trough, preventing it from falling off or shifting. This ensures that the magnetizer 605 can continuously and stably magnetize the water flow, guaranteeing the stable performance of the entire hydroelectric power generation control box.

[0047] Furthermore, the micro hydroelectric generator 5 includes a housing, an impeller, a shaft, and a generator coil. The impeller is mounted on the shaft, which is supported within the housing by bearings. The generator coil is mounted within the housing and is positioned opposite to the shaft. The inlet and outlet of the micro hydroelectric generator 5 are both located on the housing.

[0048] In this embodiment, the outer casing provides protection and support for the internal impeller, shaft, and generator coils. The casing not only prevents external debris from entering the generator and damaging its internal structure, but also prevents water leakage to a certain extent, ensuring that all components operate in a stable environment and providing a fundamental guarantee for the normal operation of the generator.

[0049] The impeller is mounted on the shaft. When water flows and impacts the impeller, it drives the shaft to rotate. This structural design allows the kinetic energy of the water to be effectively transferred to the shaft, achieving initial energy conversion. Because the impeller and shaft are directly connected, energy loss during the transfer process is minimal, ensuring the efficiency of converting water energy into mechanical energy and providing a stable power source for the subsequent power generation coils.

[0050] The generator coil is housed inside the casing and opposite to the rotating shaft. When the shaft drives the impeller to rotate, it causes a change in the magnetic field around the generator coil. According to the principle of electromagnetic induction, this change in magnetic field can generate an induced current in the coil, thereby converting mechanical energy into electrical energy. This enables the miniature hydroelectric generator 5 to stably convert the kinetic energy of water flow into electrical energy output.

[0051] Furthermore, the surfaces of the impeller and the shaft are provided with an anti-fouling coating.

[0052] When water flows through the micro hydroelectric generator 5, it typically contains minerals and other components that can easily deposit and form scale over long-term use. In this embodiment, the anti-scaling coating forms a barrier on the impeller and shaft surfaces, preventing scale from directly contacting the metal surfaces. This reduces the chance of scale adhering to the impeller and shaft, lowering the risk of component damage or reduced power generation efficiency due to scale buildup.

[0053] Because the anti-scaling coating reduces the likelihood of scale buildup, it also reduces the frequency of cleaning and maintenance of the impeller and shaft. In practical use, this reduced maintenance not only saves time and labor costs but also makes the micro hydroelectric generator 5 easier to use, allowing the equipment to continuously and stably supply power to related devices and ensuring the normal operation of the entire system.

[0054] Furthermore, the anti-scaling coating is a polytetrafluoroethylene coating or a ceramic coating.

[0055] In this embodiment, the polytetrafluoroethylene coating has an extremely low coefficient of surface friction. This characteristic makes it difficult for scale to adhere to the surface of the impeller and shaft with this coating when water flows over them. Even if impurities are present in the water, they are not easily retained by the water flow, thus effectively reducing the risk of scale buildup, ensuring the smooth rotation of the impeller and shaft, and maintaining the power generation efficiency of the micro hydroelectric generator 5.

[0056] The ceramic coating possesses excellent chemical stability and corrosion resistance. During the operation of the micro hydroelectric generator 5, facing water flow containing various chemical components, the ceramic coating can protect the impeller and shaft from corrosion. Simultaneously, its smooth surface also discourages scale adhesion, reducing damage to the equipment caused by corrosion and scale buildup, extending the service life of the impeller and shaft, and thus improving the overall reliability of the micro hydroelectric generator 5.

[0057] Furthermore, the box body 1 has a drain port 9 located opposite the mounting hole.

[0058] In this embodiment, during the process of the filter device 6 intercepting impurities in the water, the impurities gradually accumulate on or around the filter device 6. With the drain outlet 9, there is no need to disassemble the entire device; operators can directly clean the accumulated impurities through the drain outlet 9, greatly saving maintenance time and effort. Regularly cleaning impurities through the drain outlet 9 prevents excessive impurities from clogging or damaging the filter device 6, ensuring that the filter device 6 maintains good filtration performance, thereby guaranteeing the continuous and stable operation of the micro hydroelectric generator 5 and reducing equipment failures caused by the failure of the filter device 6.

[0059] Furthermore, the filter tube 601 is made of stainless steel with a mesh size of 50-100 mesh.

[0060] In this embodiment, stainless steel has excellent corrosion resistance, effectively resisting the erosion of various chemicals in the water when the hydroelectric power generation control box is in long-term contact with water flow. This means that the filter screen 601 is not prone to rust or damage during use, and can maintain a stable structure and filtration performance for a long time, ensuring the continuity of the filtration effect and reducing the occurrence of filtration failure due to material damage.

[0061] The mesh size is set between 50 and 100 mesh, which determines the filtration accuracy of the filter screen 601. A 50-100 mesh filter screen 601 can effectively intercept larger particles of impurities in the water, such as sand and rust. If these impurities enter the micro hydroelectric generator 5, they will cause blockages, affecting power generation efficiency and even damaging the equipment. This level of filtration prevents these harmful impurities from entering the generator, ensuring the normal operation of the micro hydroelectric generator 5 and maintaining stable power generation efficiency.

[0062] Furthermore, the magnetizer 605 is a permanent magnet or an electromagnet with a magnetic field strength of 1000-3000 Gauss.

[0063] In this embodiment, the magnetic field generated by the permanent magnet or electromagnet can affect the mineral ions in the water as water flows through it. Within this magnetic field strength range, the movement state of some mineral ions can be changed, preventing them from accumulating on the impeller and shaft surfaces to form scale, reducing the rate of scale deposition, and ensuring the cleanliness of the internal components of the micro hydroelectric generator 5.

[0064] Magnetizer 605, with a magnetic field strength of 1000-3000 Gauss, magnetizes the water flow and alters some of its physical properties. Magnetized water may exhibit changes in its solubility and permeability, which helps reduce the adhesion of impurities to filter device 6, resulting in more stable filtration performance. Impurities are less likely to clog filter device 6, ensuring smooth water flow and improving the overall efficiency of the hydroelectric control box.

[0065] 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.
