Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to a hydropower generation technology. Background Art

[0002] In order to improve the water quality of piped drinking water, most households have been installing and using water purifiers in recent years. However, after the piped drinking water is connected to the water purifier, the water pressure in the water flow channel of the water purifier often decreases, and the weak water pressure is difficult to drive the generator to generate electricity. The water output of some water purifiers is even very small, which further increases the difficulty of power generation. Utility Model Content

[0003] The purpose of the present utility model is to provide a self-generating device for the water flow channel of a water purifier to solve at least one of the above-mentioned technical problems.

[0004] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0005] A self-generating device for a water flow channel of a water purifier, comprising a water flow channel of the water purifier, wherein a self-generating device is connected to the water flow channel of the water purifier;

[0006] The self-generating device includes a housing having a water inlet and a water outlet;

[0007] The self-generating device is serially connected to the water flow channel of the water purifier through the water inlet and the water outlet;

[0008] The water inlet is arranged above the shell, and the water outlet is arranged below the shell;

[0009] A rotating wheel is provided in the housing, and the rotating wheel includes a rotating shaft and connecting rods arranged around the rotating shaft, and a water container with an opening is provided at the end of each connecting rod;

[0010] The water container has a position below the water inlet in the rotation trajectory, and in this position, the opening of the water container faces the water inlet;

[0011] The opening area of ​​the water container matches the opening area of ​​the water inlet;

[0012] The opening area of ​​the water container shall not be less than the opening area of ​​the water inlet;

[0013] The utility model also comprises a generator, wherein the rotating shaft is connected to the rotor of the generator in a transmission manner.

[0014] In the above design, the water inlet is located above the housing, and water from the water inlet enters the housing vertically under the action of gravity. The water container has a position below the water inlet in its rotation trajectory. In this position, the opening of the water container faces the water inlet to receive water entering vertically from the water inlet. The opening area of ​​the water container matches the opening area of ​​the water inlet, and is preferably not less than the opening area of ​​the water inlet. Compared to conventional impellers, the water container, in addition to being able to receive the impact force of the water flow like an impeller to generate torque to drive the rotating shaft, has another advantage that impellers do not have. This advantage is reflected in the fact that when the water flow is small and the impact force of the water flow is insufficient to drive the water container, the water container can accumulate a small amount of water in the container. The gravity of the accumulated water then acts on the center of the water container. Since the water container is located at the end farthest from the rotating shaft, the lever arm is longer, so the gravity of the accumulated water can easily drive the water container down. In addition, a relatively small amount of water flow can be accumulated in the water container to generate a large torque, thereby solving the technical problem of small water flow being difficult to generate electricity.

[0015] Furthermore, the self-generating device further comprises a water storage chamber, and the water flow channel of the water purifier is connected to the water inlet of the housing through the water storage chamber;

[0016] The water storage chamber is arranged above the water inlet, and the outlet of the water storage chamber is connected to the water inlet of the shell;

[0017] The outlet of the water storage chamber is also provided with a valve device;

[0018] The valve device comprises a valve body and a rotatable valve disc;

[0019] The valve disc is linked to an elastic reset mechanism that drives the valve disc to reset and close;

[0020] It also includes a magnet disposed on the valve body and another magnetic component disposed on the valve plate;

[0021] When the valve disc is in a closed state, the magnet is magnetically coupled to another magnetic component.

[0022] In the above design, a water storage system is used to accumulate small water flows in the water storage chamber. When the small water flow accumulates to a certain water level, its water pressure can break through the magnetic attraction between the valve plate and the valve body. The larger amount of accumulated water can strongly drive the impeller to rotate, thereby achieving power generation.

[0023] Without the water storage process, the small water flow will find it difficult to push the water container, and thus will not be able to drive the rotor of the generator to rotate and generate electricity.

[0024] Further preferably, the valve body adopts the pipe wall of the outlet.

[0025] In the above design, the valve body is arranged on the pipe wall of the outlet, and the rotatable valve plate is closed on the outlet to form a valve device, which has the beneficial effect of simplifying the structure and reducing the manufacturing cost.

[0026] Further preferably, the magnet and another magnetic component are matched so that the magnetic coupling force meets the following conditions:

[0027] Selection of magnetic coupling force for matching relationship:

[0028] The magnetic coupling force is greater than the pressure on the valve disc before the water storage chamber is filled with half of water;

[0029] The magnetic coupling force is smaller than the pressure on the valve plate after the water storage chamber is filled with two-thirds of water.

[0030] In the above design, the magnetic attraction between the rotatable valve disc and the valve body is set so that the valve disc is closed and cannot be opened before the water storage chamber is filled with one-half of water; after the water storage chamber is filled with two-thirds of water, the valve disc rotates to open the valve, and the water in the water storage chamber flows into the water inlet, pushing the water container, driving the rotating shaft to rotate and generate electricity.

[0031] Furthermore, a radial labyrinth seal is used between the rotating shaft and the housing.

[0032] In this design, a small, tortuous gap exists between the shaft and the housing, creating a flow path with significant flow resistance. This prevents water from leaking out of the gap between the shaft and the housing. The radial labyrinth seal is large in the radial direction, allowing for easy placement on the housing sidewall. However, it is compact in the axial direction, minimizing the distance between the housing and the generator.

[0033] Furthermore, 6 to 12 water containers are provided.

[0034] In the above design, if too many water containers are provided, the weight of the runner will be increased and the energy of the water flow will be wasted. If too few water containers are provided, the water flow cannot be effectively and continuously received, thus affecting the power generation efficiency.

[0035] Experimental verification shows that the optimal number of water containers is 6 to 8. 6 to 8 water containers can smoothly receive the water flow and drive the shaft to rotate.

[0036] Furthermore, the angle between the opening plane of the water container and the connecting rod is between 15 and 30 degrees.

[0037] In the above design, when the water container receives water flow below the water inlet, the water flow impacts the container. Due to the angle between the water flow and the container, the force applied is split along both the horizontal and vertical planes of the container. The vertical force split is smaller, resulting in less torque on the rotating shaft. Therefore, in this design, the angle between the water container opening plane and the connecting rod is between 15 and 30 degrees. This design further splits the force in the vertical plane when the water container receives water flow, thereby generating greater torque on the rotating shaft and improving power generation efficiency.

[0038] Furthermore, the rotor is a rotor having magnetic properties, which is at least one of a permanent magnet and an electromagnet.

[0039] In the above design, the rotor can use permanent magnets and the stator can use induction coils; or the rotor can use induction coils and the stator can use permanent magnets. The preferred solution is to use permanent magnets in the rotor, which has been verified by experiments to have better power generation efficiency.

[0040] The permanent magnet is preferably a neodymium iron boron magnet, which has strong magnetism and its magnetic performance far exceeds that of several other magnets.

[0041] Furthermore, the rotating wheel is made of polyetheretherketone material, and the surface is coated with a silver layer with a thickness of 30 to 40 μm.

[0042] In the above design, the polyetheretherketone (PEEK) polymer material has excellent chemical resistance, high impact resistance, wear resistance and other properties. It is a lightweight and strong food-grade plastic and is suitable for the wheel component of the present invention.

[0043] The beneficial effect of coating a silver layer on a polyetheretherketone (PEEK) polymer material is that silver ions also have a bactericidal effect.

[0044] In the present invention, the water inlet is arranged above the shell, allowing the water flow to enter the shell vertically from the water inlet. This design can maximize the impact force of the water flow. The opening area of ​​the water container matches the opening area of ​​the water inlet. If the impact force of the water flow is not enough to push the water container, the water flow can first accumulate in the water container. Then, relying on the gravity of the stored water, the force of its gravity falls on the center of the water container. The water container is located at the end away from the rotating shaft, so the lever arm is long. Therefore, the gravity of the stored water can easily drive the water container to fall. In turn, a relatively small water flow can be accumulated in the water container to generate a large torque, thereby solving the technical problem of small water flow being difficult to generate electricity.

[0045] For the water flow channel of the water purifier with small water flow, this design has another technical solution. A water storage chamber is set above the water inlet to accumulate the small water flow in the water storage chamber. When the small water flow accumulates to a certain amount, the valve plate opens and the stored water is released. The strong water flow drives the water container to rotate, and then drives the rotating shaft to rotate to achieve power generation, thus solving the problem that small water volume cannot generate electricity.

The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it designate a separate or selective embodiment that is mutually exclusive with other embodiments.

[0058] Reference Figure 1 、 Figure 2 、 Figure 3 As shown, the water flow channel self-generating device of the water purifier includes a water flow channel of the water purifier, and a self-generating device is connected to the water flow channel of the water purifier;

[0059] The self-generating device comprises a housing 3 having a water inlet 1 and a water outlet 2;

[0060] The self-generating device is serially connected to the water flow channel of the water purifier through the water inlet 1 and the water outlet 2;

[0061] The water inlet 1 is arranged above the shell 3, and the water outlet 2 is arranged below the shell 3;

[0062] A rotating wheel 5 is provided in the housing 3. The rotating wheel 5 includes a rotating shaft 7 and connecting rods 6 arranged around the rotating shaft 7. A water container with an opening is provided at the end of each connecting rod 6.

[0063] The water container has a position below the water inlet 1 in the rotation trajectory, and in this position, the opening of the water container faces the water inlet 1;

[0064] The opening area of ​​the water container matches the opening area of ​​the water inlet 1;

[0065] The opening area of ​​the water container is not less than the opening area of ​​the water inlet 1;

[0066] The system further comprises a generator 4 , and a rotating shaft 7 is drivingly connected to a rotor 8 of the generator 4 .

[0067] In this embodiment, the water inlet 1 is arranged above the shell 3, and the water flow of the water inlet 1 enters the shell 3 vertically under the action of gravity. In the rotation trajectory of the water container, there is a position below the water inlet 1, and at this position, the opening of the water container faces the water inlet 1 to receive the water flow entering vertically from the water inlet 1. The container opening area of ​​the water container matches the opening area of ​​the water inlet 1, and is preferably not less than the opening area of ​​the water inlet 1.

[0068] Compared with conventional impellers, the water container can not only receive the force of the water flow impact and generate torque to drive the rotation of the shaft like the impeller, but also has another advantage that the impeller does not have. This advantage is reflected in that when the water flow is small and the impact force of the water flow is not enough to push the water container, the advantage is that the water container can accumulate a small water flow in the container, and then rely on the gravity of the stored water. The force of its gravity falls on the center of the water container, and the water container is located at the end away from the rotation shaft 7, so the lever arm is longer, so the gravity of the stored water can easily drive the water container to fall, and then a relatively small water flow can be accumulated in the water container to generate a larger torque, thereby solving the technical problem that small water flow is difficult to generate electricity.

[0069] Reference Figure 4 As shown, the self-generating device further includes a water storage chamber, and the water flow channel of the water purifier is connected to the water inlet 1 of the housing 3 through the water storage chamber;

[0070] The water storage chamber is arranged above the water inlet 1, and the outlet of the water storage chamber is connected to the water inlet 1 of the shell 3;

[0071] The outlet of the water storage chamber is also provided with a valve device;

[0072] The valve device comprises a valve body and a rotatable valve disc 12;

[0073] The valve disc 12 is linked to an elastic reset mechanism that drives the valve disc 12 to reset and close;

[0074] It also includes a magnet 14 disposed on the valve body, and another magnetic component disposed on the valve plate 12;

[0075] When the valve plate 12 is in the closed state, the magnet 14 is magnetically coupled to another magnetic component.

[0076] In this embodiment, a water storage system 11 is used to accumulate a small water flow in the water storage chamber. When the small water flow accumulates to a certain water level, its water pressure can break through the magnetic attraction between the valve plate 12 and the valve body. The larger amount of accumulated water can strongly drive the impeller 5 to rotate, thereby achieving power generation.

[0077] Without the water storage process, the small water flow will have difficulty in pushing the water container, and thus will not be able to drive the rotor 8 of the generator 4 to rotate and generate electricity.

[0078] Further preferably, the valve body adopts the pipe wall of the outlet.

[0079] In this embodiment, the valve body is arranged on the pipe wall of the outlet, and the rotatable valve plate 12 is closed on the outlet to form a valve device, which has the beneficial effects of simplifying the structure and reducing the manufacturing cost.

[0080] Further preferably, the magnet 14 and another magnetic component are matched so that the magnetic coupling force meets the following conditions:

[0081] Selection of magnetic coupling force for matching relationship:

[0082] The magnetic coupling force is greater than the pressure on the valve plate 12 before the water storage chamber is filled with half of water;

[0083] The magnetic coupling force is smaller than the pressure on the valve plate 12 after the water storage chamber is filled with two-thirds of water.

[0084] In this embodiment, the magnetic attraction between the rotatable valve disc 12 and the valve body is set so that before the water storage chamber is filled with one-half of water, the valve disc 12 is closed and cannot be opened; after the water storage chamber is filled with two-thirds of water, the valve disc 12 rotates to open the valve, and the water in the water storage chamber flows into the water inlet 1 to push the water container, driving the rotating shaft 7 to rotate and generate electricity.

[0085] Reference Figure 3 As shown, a radial labyrinth seal 10 is used between the rotating shaft 7 and the housing 3 .

[0086] In this embodiment, a small, tortuous gap is formed between the rotating shaft 7 and the housing 3, thereby forming a flow path with extremely high flow resistance, thereby preventing water in the housing 3 from leaking out through the gap between the rotating shaft 7 and the housing 3. The radial labyrinth seal 10 is relatively large in the radial direction, allowing for easy installation on the sidewall of the housing 3. However, it is compact in the axial direction, reducing the distance between the housing 3 and the generator 4.

[0087] Reference Figure 1 As shown, 6 to 12 water containers are provided.

[0088] In this embodiment, if too many water containers are provided, the weight of the runner 5 will be increased, and the energy of the water flow will be wasted. If too few water containers are provided, the water flow cannot be effectively and continuously received, and the power generation efficiency will be affected.

[0089] According to experimental verification, the optimal number of water containers is 6 to 8. 6 to 8 water containers can smoothly receive the water flow and drive the rotating shaft 7 to rotate.

[0090] Reference Figure 5 As shown, the angle A between the opening plane of the water container and the connecting rod 6 is between 15 and 30 degrees.

[0091] In this embodiment, when the water container enters below the water inlet 1 and receives water flow, the water flow impacts the water container. Due to the angle A between the water flow and the water container, the angle A causes the force to be decomposed along both the horizontal and vertical planes of the water container. The force decomposed in the vertical plane is smaller, resulting in a smaller torque on the rotating shaft 7. Therefore, in this design, the angle A between the water container opening plane and the connecting rod 6 is between 15 and 30 degrees. This design can further decompose the force in the vertical plane when the water container receives water flow, thereby generating a greater torque on the rotating shaft 7 and improving power generation efficiency.

[0092] Reference Figure 3 As shown, the rotor 8 is a rotor 8 having magnetic properties, which is at least one of a permanent magnet 14 and an electromagnet.

[0093] In this embodiment, the rotor 8 may use permanent magnets 14, while the stator uses induction coils 9; or the rotor 8 may use induction coils 9, while the stator uses permanent magnets 14. The preferred solution is that the rotor 8 uses permanent magnets 14, which has been verified by experiments to have better power generation efficiency.

[0094] The permanent magnet 14 is preferably a neodymium iron boron magnet, which has strong magnetism and its magnetic properties far exceed those of several other magnets.

[0095] Furthermore, the rotating wheel 5 is made of polyetheretherketone, and the surface of the rotating wheel 5 is coated with a silver layer with a thickness of 30 to 40 μm.

[0096] In this embodiment, the polyetheretherketone (PEEK) polymer material has excellent chemical resistance, high impact resistance, wear resistance and other properties. It is a lightweight and strong food-grade plastic and is suitable for the wheel 5 component of the present invention.

[0097] The beneficial effect of coating a silver layer on a polyetheretherketone (PEEK) polymer material is that silver ions also have a bactericidal effect.

[0098] Furthermore, in order to provide a concise description of the exemplary embodiments, all features of the actual embodiment may not be described, i.e., those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention.

[0099] It should be understood that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but for those of ordinary skill having the benefit of this disclosure, the development effort will be a routine task of design, fabrication, and production without undue experimentation.

[0100] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
