Description

Technical Field

[0001] The present invention relates to the field of water pipe hydroelectric power generation, and particularly to a water pipe power generation device and a setting method thereof. Background Art

[0002] With the continuous advancement of the urbanization process in China, the energy demand continues to grow, and the contradiction between energy supply and demand has become increasingly prominent. In order to achieve sustainable energy development, on the one hand, it is necessary to "open up new sources", develop new energy and renewable energy such as nuclear power and wind power, and on the other hand, it is also necessary to "reduce consumption" and vigorously implement energy conservation and emission reduction. Generating electricity using renewable resources such as wind energy, water energy, and solar energy is an important means on the road to sustainable energy development.

[0003] The current power generation methods mainly involve building large power stations, nuclear power plants, hydropower stations or large thermal power plants, and setting up long-distance high-voltage transmission lines for centralized power supply. This not only costs huge amounts of money but also causes environmental pollution and affects the ecological balance.

[0004] However, in the water supply and drainage pipe networks scattered throughout the city, the potential energy generated by the water level drop during water flow could have been used for power generation, but it has not been fully utilized, which also indirectly causes energy waste. Although there are already some water pipe power generation devices on the market, most of these devices directly set the water wheel in the center position of the water pipe. When the water body flows to the water wheel, it will impact the entire water wheel. Part of the water body drives the water wheel to rotate forward, and another part of the water body drives the water wheel to rotate backward, which makes the potential energy of the water body cancel each other out and reduces the power generation efficiency of the water pipe power generation device. In addition, due to the gap between the water wheel and the water pipe, part of the water body will fall along the inner wall of the water pipe without contacting the water wheel, and this part of the water body will not impact the water wheel, further reducing the power generation efficiency. Therefore, the power generation efficiency of these water pipe power generation devices is not high.

[0005] Therefore, there is an urgent need for a water pipe power generation device with high power generation efficiency to solve the problem of low power generation efficiency caused by the water body driving the water wheel to rotate forward and backward simultaneously when impacting the water wheel and part of the water body not contacting the water wheel. Summary of the Invention

[0006] The object of the present invention is to provide a water pipe power generation device and a setting method. Through the double diversion effects of the first wedge block and the second wedge block, all water bodies can impact the water wheel, and always impact the same position of the water wheel, thereby ensuring that the water wheel rotates in the same direction, effectively improving the power generation efficiency of the water pipe power generation device, and solving the problems that the water potential energy is mutually offset when the water body impacts the water wheel and causes the water wheel to rotate forward and backward simultaneously, and part of the water body does not contact the water wheel and cannot impact the water wheel. By further diverting the water body through the water body diversion cover, the water body that has impacted the water wheel flows down along the inner wall of the water body diversion cover, preventing the water body from splashing, eliminating the influence of the water body splashing and impacting the water wheel again on the rotation of the water wheel, and further improving the power generation efficiency.

Detailed Embodiments

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0033] The object of the present invention is to provide a water pipe power generation device. Through the double flow guiding effects of the first wedge block and the second wedge block, all water bodies can impact the water wheel, and always impact the same position of the water wheel, thereby ensuring that the water wheel rotates in the same direction, effectively improving the power generation efficiency of the water pipe power generation device, and solving the problems of mutual cancellation of the water body potential energy caused by the impact of the water body in multiple directions on the water wheel and the problem that some water bodies cannot contact the water wheel and cannot impact the water wheel.

[0034] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Embodiment 1

[0036] Figure 1 It is a partial cross-sectional view of the water pipe of the water pipe power generation device provided for Embodiment 1. Figure 2 It is an overall structure diagram of the water pipe power generation device provided for Embodiment 1, where the black arrow indicates the water body flow direction.

[0037] As Figure 1 and Figure 2 shown, this embodiment provides a water pipe power generation device, which specifically includes: a water pipe 1, a water body flow guiding cover 2, a water wheel 3, a generator rotating shaft 4, a generator 5, a first wedge block 6, a second wedge block 7, a base 8, a base connection block 9, bolt mounting holes 10, a power output module 11 and a power output interface 12.

[0038] Among them, the water pipe 1 is used to convey the water body. The water pipe 1 is a tubular structure with openings at both ends, and the openings at both ends of the water pipe 1 are respectively a water pipe inlet 101 and a water pipe outlet 102. The water pipe 1 can be metal pipes of various sizes, such as hot-dip cast iron pipes with plastic lining inside, copper pipes, stainless steel pipes, etc., or plastic-coated metal pipes, such as steel-plastic composite pipes, aluminum-plastic composite pipes, etc., or plastic pipes, such as PVC pipes, PB pipes, PP-R pipes, etc. In addition, the water pipe 1 also needs to have a certain hardness and corrosion resistance.

[0039] The water body flow guiding cover 2 is sleeved on the notch on the surface of the water pipe 1 and is hermetically connected to the water pipe 1, and is used to make the water body flow along the inner wall of the water body flow guiding cover 2 to guide the water body. The water wheel 3 is located inside the water body flow guiding cover 2, and a generator rotating shaft 4 is provided at the center of the water wheel 3. The water wheel 3 is used to bear the impact of the water body and rotate, convert the potential energy of the water body into mechanical energy, and drive the generator 5 to generate electricity.

[0040] It should be noted that the number of blades of the water wheel 3 in this embodiment is not limited, and Figure 1 and Figure 2 are only pictures drawn and presented to make it easier for people to understand the solution of the present invention. Figure 1 and Figure 2 The number of blades of the water wheel 3 shown in is only for illustration and should not be used as a limitation on the protection scope of the present invention. The number of blades of the water wheel 3 can be 3, 5, 6 or more, and can be set according to specific circumstances.

[0041] It should also be noted that a notch having the same size as the open end of the water body guide cover 2 is provided on the outer surface of the water pipe 1. The water body guide cover 2 and the water pipe 1 can be of an integrally formed structure or two separate structures. When they are two independent structures, the water body guide cover 2 needs to be fixed to the water pipe 1 by bolts and a rubber pad is provided between them, or the water body guide cover 2 and the water pipe 1 are directly bonded with waterproof glue, so as to ensure the sealing and waterproof effects of the water body guide cover 2. This embodiment preferably adopts the installation method of bolts and rubber pads, which is convenient for disassembling and cleaning the water wheel 3.

[0042] The inner surface of the water body guide cover 2 is a smooth curved surface, so that the water body splashing after impacting the water wheel 3 can better flow down along the inner wall of the water body guide cover 2 and flow to the water pipe outlet 102, realizing the collection and diversion of the water body, preventing the splashing water body from exerting a reaction force on the water wheel 3 to drive the water wheel 3 to rotate in reverse, ensuring that the water wheel 3 always rotates in the same direction, and improving the power generation efficiency of the device. The water body guide cover 2 is preferably made of transparent PVC material to facilitate checking the running state and dirt degree of the water wheel 3.

[0043] The first wedge block 6 and the second wedge block 7 are respectively fixedly installed on the inner wall of the water pipe 1. The first wedge block 6 is used for the first-stage diversion of the water body, that is, diverting the water body directly above the water wheel 3 to the second wedge block 7, preventing the water body from directly impacting the water wheel 3 and causing the water wheel 3 to rotate in the reverse direction. The second wedge block 7 is used for the second-stage diversion of the water body, that is, further diverting the water body flowing straight down and the water body diverted to the second wedge block 7, and directly diverting the water body to the water wheel 3, so that the water body impacts the same position of the water wheel 3 in the same direction, ensuring that the water wheel 3 always rotates forward.

[0044] The first wedge block 6 further includes a first guide plate 601. One end of the first guide plate 601 is connected to the end of the inclined surface of the first wedge block 6, and the other end is connected to the connection between the water body guide cover 2 and the water pipe 1, that is, at the highest point on the circumference of the connection between the water body guide cover 2 and the water pipe 1. The first guide plate 601 and the inclined surface of the second wedge block 7 form a first diversion channel to divert the water body, so that the water body flows in the first diversion channel and reaches directly above the water wheel 3. This not only prevents the water body from splashing onto the inner wall of the water pipe 1, but also, due to the restriction of the flow path of the water body by the first diversion channel, aggregates and converges the water body, making the water pressure of the water body flowing along the first diversion channel greater and more impactful.

[0045] The second wedge block 7 further includes a second guide plate 701. The second guide plate 701 includes a diversion bent plate and a diversion straight plate. One end of the diversion bent plate is connected to the end of the inclined surface of the second wedge block 7, and the other end is connected to the diversion straight plate. The other end of the diversion straight plate is fixed to the inner wall of the water pipe 1. A circular cavity is formed between the diversion bent plate and the water body guide cover 2. The water wheel 3 is arranged in the circular cavity. The circular cavity can not only protect the water wheel 3, but also divert some of the water body thrown out when the water wheel 3 rotates, and discharge the water body from the water pipe outlet 102 through the diversion straight plate. The second guide plate 701, the water body guide cover 2 and the inner wall of the water pipe 1 constitute a second diversion channel to further divert the water body.

[0046] In this embodiment, the first guide plate 601, the second wedge block 7, the second guide plate 701 and the water body guide cover 2 together form a complete water body diversion channel, enabling all water bodies to flow within the water body diversion channel. This not only avoids the occurrence of water body splashing, diverts all water bodies to fully impact the water wheel 3, but also, restricted by the water body diversion channel, effectively reduces the cross-sectional area when the water body flows, increases the kinetic energy of the water body, makes the impact force of the converged water body stronger, makes the water wheel 3 rotate faster, and thus improves the power generation efficiency.

[0047] In this embodiment, when only one wedge block is provided, since the water pressure is sometimes too high, the impact force of the water on the wedge block will be too large. At this time, with only one wedge block to block, the water will splash. The splashed water hits the inner wall of the water pipe 1 on the other side of the wedge block, so that the water splashed onto the inner wall of the water pipe 1 flows down along the inner wall of the water pipe 1 again, and cannot effectively impact the water wheel 3. Therefore, in this embodiment, two wedge blocks, i.e., a first wedge block 6 and a second wedge block 7, are provided. The first wedge block 6 and the second wedge block 7 are arranged opposite to each other in the horizontal direction and have a spacing in the vertical direction, that is, the second wedge block 7 is located on the inner wall of the water pipe 1 on the other side opposite to the first wedge block 6. The first wedge block 6 and the second wedge block 7 cooperate with each other. The water splashed up after reaching the first wedge block 6 converges along the inner wall of the water pipe 1 to the second wedge block 7, and all the water can be diverted to the water wheel 3 through the second wedge block 7, thus solving the problem that the splashed water flows down along the inner wall of the water pipe 1 due to a single wedge block and cannot effectively impact the water wheel 3.

[0048] It should be noted that the forward rotation may be that the water wheel 3 rotates in the clockwise direction, and the reverse rotation may be that the water wheel 3 rotates in the counterclockwise direction. Or, the forward rotation may also be that the water wheel 3 rotates in the counterclockwise direction, and the reverse rotation may also be that the water wheel 3 rotates in the clockwise direction. In this embodiment, the specific rotation direction of the water wheel 3 is not limited, as long as it is ensured that after the water passes through the diversion of the first wedge block 6 and the second wedge block 7, it always impacts the same position of the water wheel 3.

[0049] That is to say, by adjusting the size of the second wedge block 7 or adjusting the distance between the second wedge block 7 and the water wheel 3 in the horizontal direction, the adjustment of the specific position where the water impacts the water wheel 3 can be realized. That is, the position where the water impacts the water wheel 3 completely depends on the size of the second wedge block 7 and the relative position between the second wedge block 7 and the water wheel 3. As long as it is ensured that the water can always impact the same position of the water wheel 3 in the same direction, it can be ensured that the water wheel 3 always rotates in the same direction. Whether the rotation direction is counterclockwise or clockwise, the power generation efficiency of the water pipe power generation device can be effectively improved.

[0050] It should be noted that in this embodiment, the size and material of the water pipe 1, the material of the water diversion cover 2, and the shapes and sizes of the first wedge block 6 and the second wedge block 7 are not limited and can be set according to specific situations. For example, the shapes of the first wedge block 6 and the second wedge block 7 can be Figure 1 triangles as shown in the figure, or other shapes with the same effect. However, it should be noted that any setting of the above shapes, sizes and materials should be within the protection scope of the present invention.

[0051] The generator 5 is disposed outside the water pipe 1 and connected to one end of the generator rotating shaft 4, and is used for converting the mechanical energy generated by the rotation of the water wheel 3 into electrical energy.

[0052] The other end of the generator rotating shaft 4 is further connected with a base 8. The base 8 is located outside the water pipe 1 and is used for the support and fixation of the water pipe power generation device. The generator 5 can be fixed to positions such as a wall or the ground through the base 8. A plurality of bolt mounting holes 10 are provided on the base 8. The base 8 is rotatably connected to the generator rotating shaft 4 through a base connecting block 9.

[0053] In this embodiment, the water wheel 3 on the generator rotating shaft 4 is located inside the water body diversion cover 2, and the generator 5 and the base 8 are respectively connected to both ends of the external generator rotating shaft 4. Moreover, wear-resistant rubber is also provided at the connection between the generator rotating shaft 4 and the water pipe 1 or the water body diversion cover 2. When the generator rotating shaft 4 rotates, the wear-resistant rubber, on the one hand, plays a role in wear resistance and damage prevention, and on the other hand, also seals the inside of the water pipe 1 and the water body diversion cover 2 to prevent the water body from flowing out from the connection between the water pipe 1 or the water body diversion cover 2 and the generator rotating shaft 4.

[0054] The power output module 11 is connected to the generator 5 and is used for storing the electrical energy generated by the generator 5 and supplying power to users through a power output interface 12. Users can directly connect household appliances through the power output interface 12 for use.

[0055] During actual use, the water body flows in from the water inlet 101 of the water pipe and first reaches the first wedge-shaped block 6. Through the guiding action of the first wedge-shaped block 6, the water body is guided to the second wedge-shaped block 7. The second wedge-shaped block 7 and the first guide plate 601 collect and guide the directly flowing water body and the guided water body, and guide all the water bodies to the water wheel 3, so that the water body always impacts the same position of the water wheel 3 in the same direction, thereby driving the water wheel 3 to rotate in the same direction all the time, and further achieving the purpose of fully utilizing all the water bodies for power generation and improving the power generation efficiency. At the same time, the rotation of the water wheel 3 will cause the water body to splash, and the splashed water body will fall on the smooth curved surface of the water body guide cover 2 and the guide bend plate of the second guide plate 701, thereby realizing the further guiding of the water body by the water body guide cover 2, so that the water body always flows down along the smooth curved surface of the inner wall of the circular cavity formed by the water body guide cover 2 and the guide bend plate, preventing the water body from splashing again, and eliminating the problem that the water body splashes again and impacts the water wheel 3 to cause a reaction force on the water wheel 3 to reverse the water wheel 3, and further improving the power generation efficiency. At the same time, the working state and dirt degree of the water wheel 3 can be directly checked through the water body guide cover 2. After it is detected that too much dirt adheres to the water wheel 3, the bolts between the water body guide cover 2 and the water pipe 1 can be removed to clean and maintain the water wheel 3, so as to extend the service life of the water wheel 3 and ensure the power generation efficiency. Then the water body flows downward along the inner wall of the water body guide cover 2 and the second guide plate 701 and is discharged from the water outlet 102 of the water pipe. At the same time, the continuous rotation of the water wheel 3 drives the generator 5 to generate electricity, and the generated electric energy is stored in the power output module 11 and supplied to the user through the power output interface 12, thereby realizing the combination of the water pipe power generation device and the existing water supply and drainage system, and the water pipe power generation device can be directly connected to the water supply and drainage system to immediately supply power to the user.

[0056] Embodiment 2

[0057] This embodiment proposes a setting method for a water pipe power generation device. At both ends of the water pipe 1 of the water pipe power generation device, a hose with a corresponding diameter is connected, and the other end of the hose is connected to the water supply pipe or drain pipe of the user.

[0058] In this embodiment, the water inlet 101 and the water outlet 102 at both ends of the water pipe power generation device in Embodiment 1 can be connected to hoses with corresponding sizes, and the water pipe power generation device can be connected to the user's water supply and drainage system in a flexible connection manner, such as at positions such as the sewer pipe and the faucet, as long as it is ensured that the water body with sufficient pressure flows through the water wheel 3 and can make the water wheel 3 rotate.

[0059] It should be noted that, in addition to the flexible connection method of the hose, waterproof glue can also be used to directly bond the water inlet 101 and the water outlet 102 at both ends of the water pipe power generation device to the water pipes 1 of the same size in the water supply and drainage system. This fixed installation method can be used at the washbasin water outlet in the bathroom, which is more stable and firm for continuous power generation. Or, flange structures can be provided at the water inlet 101 and the water outlet 102 at both ends of the water pipe power generation device and connected to the flange water outlets of the same size in the water supply and drainage system. The water pipe power generation device can be connected to the water supply and drainage system by means of bolt fixation. This situation is mostly used in factories or collective water supply and drainage pipes. In this embodiment, the connection method of the hose is preferably used. By matching with a suitable hose, the water pipe power generation device can be connected to any water outlet pipe in the water supply and drainage system. It is flexible to disassemble, can be disassembled as needed, has a richer application scenario, and is more convenient to use.

[0060] The present invention provides a water pipe power generation device and a setting method. By providing a first wedge block 6 and a second wedge block 7, the first wedge block 6 is used for the first-stage diversion of the water body, that is, blocking the water body directly above the water wheel 3 to prevent the direct impact of the water body directly above from causing the water wheel 3 to rotate in the reverse direction; the second wedge block 7 is used for the second-stage diversion of the water body, that is, controlling the water body to impact the same position on the water wheel 3 along the same inclined direction to ensure that the water wheel 3 always rotates in the forward direction. Through the dual diversion effects of the first wedge block 6 and the second wedge block 7, and in cooperation with the first diversion plate 601 and the second diversion plate 701, a complete water body diversion channel is formed. Under the diversion effect of the water body diversion channel, all water bodies can strongly impact the water wheel 3 and always impact the same position of the water wheel 3, so as to ensure that the water wheel 3 rotates in the same direction, effectively improving the power generation efficiency of the water pipe power generation device and solving the problems that the potential energy of the water body is mutually offset due to the simultaneous forward and reverse rotation of the water wheel 3 when the water body impacts the water wheel 3, and that part of the water body cannot contact the water wheel 3 and cannot impact the water wheel 3. Through the further diversion of the water body by the water body diversion cover 2, the water body that has impacted the water wheel 3 flows down along the inner wall of the water body diversion cover 2 and the diversion curved plate of the second diversion plate 701, preventing the water body from splashing again and eliminating the influence of the water body splashing and impacting the water wheel 3 again on the rotation of the water wheel 3, further improving the power generation efficiency.

[0061] Each embodiment in this specification focuses on the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other. Specific examples are used in this specification to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, there will be changes in the specific implementation manner and application scope according to the idea of the present invention.
