[0020] The present invention has the following advantages and beneficial effects:

[0021] The present invention has successfully achieved a significant expansion and upgrade of the functions of the traditional drainage system by effectively combining the drainage system with the power generation module. Specifically, the present invention utilizes the water flow in the drainage system to flow through the power generation module installed in the drainage pipe under the action of natural gravity. The water wheel in the power generation module rotates under the impetus of the water flow, and efficiently converts the kinetic energy of the water flow into electrical energy. The generated electrical energy is transmitted to the electric energy storage module in real time for storage, realizing the effective recovery of the kinetic energy of water resources in the drainage pipe. This move not only significantly improves the efficiency of energy utilization, but also reduces the cost of energy use and effectively reduces carbon emissions. Through this innovative solution, the drainage system can not only continue to perform its traditional functions, but also play an important role in energy recovery and energy conservation, providing a reliable solution for green buildings and sustainable development.

[0022] This design makes full use of the existing drainage system inside the building, converting the kinetic energy of water that would otherwise be lost into reusable electrical energy, thus maximizing energy utilization. Especially in multi-story or high-rise buildings, due to the large drainage volume and water flow velocity, the amount of electricity generated by the power generation module also increases accordingly, providing a relatively stable source of power input for the energy storage module.

[0023] The electric energy stored in the electric energy storage module can be efficiently managed and dispatched through the control module to drive the tap water supply system, especially the operation of the electric water pump. This means that the tap water supply of high-rise buildings can rely on the electric energy generated by the present invention to a large extent, thereby reducing dependence on municipal electricity, reducing the load on the power grid, and reducing power consumption and cost expenditure.

[0024] In addition, the system achieves dual utilization of energy without affecting the normal drainage function of the drainage system, ensuring efficient drainage of the building and realizing energy recovery and reuse through the power generation module, forming an environmentally friendly and efficient energy circulation system. In this way, it can not only reduce the demand for traditional grid electricity, but also cope with the peak electricity consumption inside the building to a certain extent, thereby further reducing the peak energy consumption.

[0025] In project management, the present invention optimizes energy efficiency, reduces energy costs, and helps project teams achieve budget control. By integrating low-carbon energy systems with existing infrastructure, external energy dependence is reduced, and long-term operating costs are reduced. During the construction and operation phases, the system helps reduce energy expenditures, improves the cost-effectiveness of the project, and reduces costs while reducing carbon emissions. This solution not only improves the overall controllability of the project cost, but also supports green sustainable development goals and enhances the economic and environmental value of the project.

[0026] The design concept of the present invention is in line with the trend of low-carbon energy conservation, which helps to reduce the overall carbon footprint of buildings, improve energy efficiency, and has significant environmental benefits and economic value. This system is particularly suitable for high-rise buildings or buildings with large drainage volumes, and can effectively convert the neglected kinetic energy of water resources in daily life into actual electrical energy utilization, providing an innovative solution for the sustainable development of residential areas.

[0038] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0039] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0040] Reference Figure 1 , Figure 2 As shown, the embodiment of the present application provides a microgrid energy system for low-carbon energy utilization, including a power generation module 100, a drainage system 500, an electric energy storage module 200, a tap water supply system 300 and a control module 400; wherein the power generation module 100 can generate electricity by driving the water flow in the drainage system 500, the electric energy storage module 200 can store the electric energy generated by the power generation module 100, and the electric energy stored in the electric energy storage module 200 can supply the tap water system. Exemplarily, the microgrid energy system is used in high-rise buildings, such as a residential area with more than 10 floors.

[0041] In some embodiments, the power generation module 100 is connected to the drainage system 500, and the power generation module 100 is driven by the water flow in the drainage system 500 to generate electricity. The power generation module 100 is connected to the drainage system 500, which means that the power generation module 100 can generate electricity using the drainage system 500. For example, the drainage system 500 is connected to the power generation module 100 through a pipeline, so that the sewage in the drainage system 500 drives the power generation module 100 to generate electricity.

[0042] In some schemes, the electric energy storage module 200 is electrically connected to the power generation module 100 to store the electric energy generated by the power generation module 100. The electric energy storage module 200 can store electric energy or release electric energy. When the power generation module 100 generates electricity, the generated electric energy can be stored in the electric energy storage module 200. The tap water supply system 300 is electrically connected to the electric energy storage module 200 and the mains system. In daily use, the tap water supply system 300 usually relies on the mains system for power supply to deliver tap water to high-rise buildings to meet the daily needs of residents. When the electric energy of the electric energy storage module 200 reaches a full load state, the module can directly supply power to the tap water supply system 300 to ensure the normal operation of the water supply system. When the electric energy in the electric energy storage module 200 drops to a preset threshold, the system automatically switches back to the mains supply, thereby effectively reducing the power consumption of the mains system.

[0043] By rationally allocating the power supply period of the energy storage module 200, energy utilization can be further optimized and costs can be saved to the maximum extent. For example, the discharge time of the energy storage module 200 is set during the peak power consumption period to reduce the dependence on the mains power system during the peak period, thereby reducing the power consumption and power costs during the peak period. In addition, this coordination strategy can also effectively alleviate the load pressure of the mains power system during the peak period, which helps to improve the stability and efficiency of the overall energy system.

[0044] In some embodiments, the control module 400 is electrically connected to the power generation module 100 and the tap water supply system 300. The control module 400 adjusts the discharge time of the power generation module 100 so that the tap water supply system 300 can use the electric energy of the power generation module 100 to supply water normally. It is understood that the tap water supply system 300 includes a water pump, and the power generation module 100 drives the water pump to transport tap water to the upper floors, thereby meeting the water needs of the residents.

[0045] Reference Figure 2 , Figure 3As shown, according to an optional embodiment, the drainage system 500 includes a drainage pipe 530, and the power generation module 100 includes a water wheel 110 disposed in the drainage pipe 530 and a generator 120 connected to the water wheel 110. The water wheel 110 can rotate under the action of the water flow in the drainage pipe 530 to drive the generator 120 to generate electricity. It can be understood that the sewage in the drainage pipe 530 will impact the water wheel 110 during the flow process, driving the water wheel 110 to rotate, thereby driving the generator 120 to generate electricity. Exemplarily, the sewage is accelerated by gravity in the drainage pipe 530. When the water flow reaches the position of the water wheel 110, the flowing water flow will hit the blades of the water wheel 110, driving the blades to rotate, thereby rotating the water wheel 110 and driving the generator 120 to generate electricity. This design utilizes the kinetic energy of the water flow and effectively realizes the recovery and reuse of energy.

[0046] According to an optional embodiment, a water collecting member 600 is provided in the drain pipe 530, and the water collecting member 600 includes a water inlet 610 and a water outlet 620. The water wheel 110 is located on the side of the water outlet 620 away from the water inlet 610, the water inlet 610 is connected to the drain pipe 530, and the size of the water outlet 620 is adjustable. It is understandable that there are peak periods and valley periods in water use and drainage in residential areas. For example, in the morning, noon and evening, due to the need for dining or cleaning, the water consumption will increase, and the amount of sewage in the drain pipe 530 will increase accordingly, so that the water wheel 110 can be driven to operate normally. However, during the valley period, the water consumption is reduced, the sewage flow in the drain pipe 530 is small, and the water flow may slowly slide down along the wall of the drain pipe 530. Due to the low water flow speed and the fact that part of the water flow flows along the pipe wall, it cannot effectively hit the water wheel 110, resulting in reduced power generation efficiency.

[0047] Reference Figure 2 , Figure 3 As shown, in order to solve this problem, a water collecting member 600 is added to the design. When the water flow in the drain pipe 530 is small, the water collecting member 600 will collect the water and discharge it through the water outlet 620. Since the water wheel 110 is located downstream of the water outlet 620, the water flow discharged from the water outlet 620 can directly hit the water wheel 110, driving it to rotate, thereby improving the power generation efficiency. This design ensures that even when there is less sewage in the drain pipe 530, effective power generation can be carried out, thereby improving the overall energy efficiency of the system. Since the size of the water outlet 620 can be adjusted, when the sewage in the drain pipe 530 suddenly increases, the water outlet 620 can be expanded in time to avoid the situation where the sewage cannot be discharged in time. Through this design, on the one hand, it can ensure that the water flow is sufficiently concentrated to drive the water wheel 110 to rotate, thereby meeting the power generation needs; on the other hand, it also ensures the normal operation of the drainage system 500, and does not cause poor drainage due to excessive water flow. This adjustment mechanism effectively balances the power generation efficiency and drainage needs, so that the system can cope with changes in drainage volume while efficiently utilizing energy.

[0048] Reference Figure 7 , Figure 8 As shown, according to an optional embodiment, the water collecting member 600 includes an elastic diaphragm 630, one end of which is fixed in the drain pipe 530, and a plurality of elastic diaphragms 630 are arranged along the circumference of the drain pipe 530, and the free end of the elastic diaphragm 630 is inclined toward the central axis of the drain pipe 530, and the free ends of the plurality of elastic diaphragms 630 surround the water outlet 620, and the free ends of the elastic diaphragms 630 can be elastically deformed in a direction away from the central axis of the drain pipe 530 under the action of water flow, so as to enlarge the water outlet 620. Figure 5 and Figure 6 As shown, the upper end of the elastic diaphragm 630 is fixed on the inner wall of the drain pipe 530, and the lower end is used as a free end. During use, these elastic diaphragms 630 are arranged circumferentially along the inner wall of the drain pipe 530 to form a flexible water-collecting structure. Through such a design, the water flow in the drain pipe 530 can be effectively concentrated and guided to ensure the power generation efficiency under different water flow conditions. Exemplarily, when the water flow is small, the force of the water flow is not enough to push the elastic diaphragm 630 to deform. At this time, the free end of the elastic diaphragm 630 will remain in a position close to the central axis of the drain pipe 530, and the water outlet 620 is relatively small, so that less sewage can be concentrated and effectively promote the water wheel 110 to rotate. When the water flow is large, the water flow speed is accelerated, which is enough to push the free end of the elastic diaphragm 630 to deform in a direction away from the central axis of the drain pipe 530, thereby increasing the water outlet 620. While meeting normal drainage needs, the water flow can still drive the water wheel 110 to rotate and achieve normal power generation. Through this design, the system can flexibly adjust the size of the water outlet 620 under different water flow conditions to ensure a balance between power generation efficiency and drainage performance.

[0049] Reference Figure 6 , Figure 7 As shown, according to an optional embodiment, the elastic diaphragm 630 includes an elastic body 631 and a flexible skirt 632 disposed on both sides of the elastic body 631, and adjacent elastic bodies 631 overlap at least partially. Through this overlapping design, it is possible to effectively prevent sewage from flowing out of the gap between adjacent elastic bodies 631, thereby improving the sewage collection effect. The flexible skirt 632 can fit tightly on the adjacent elastic bodies 631 under the action of water flow, further enhancing the sealing between adjacent elastic bodies 631. This design not only improves the sewage collection effect, but also ensures that the water flow can pass through the water outlet 620 in a concentrated manner, thereby more effectively driving the water wheel 110 to rotate and improving the power generation efficiency.

[0050] Exemplarily, the elastomer 631 can be made of an elastic plastic sheet, and the flexible skirt 632 can be made of an elastic plastic film. This material combination can provide the required elastic deformation under the action of water flow while ensuring sufficient sealing. Materials suitable for the elastomer 631 include polyurethane (PU) and polyethylene (PE), which have excellent durability and elasticity. The material of the flexible skirt 632 can be selected from thermoplastic elastomer 631 (TPE) or silicone film, which has good flexibility and fatigue resistance, and can fit tightly on the adjacent elastomer 631 under the action of water flow, ensuring sealing and improving the sewage collection effect.

[0051] According to an optional embodiment, a plurality of embedded grooves 640 are provided on the elastic body 631 along the central axis direction of the drain pipe 530, at least part of the embedded grooves 640 are located on both sides of the elastic body 631, and at least part of the flexible skirt 632 can be embedded in the embedded grooves 640 under the action of water pressure. Due to its greater flexibility, the flexible skirt 632 can be deformed under the action of water flow and enter the embedded grooves 640, thereby enhancing the sealing between adjacent elastic diaphragms 630. In addition, this embedded design helps multiple elastic diaphragms 630 to form an integral structure, further improving the collection effect of sewage, ensuring that the water flow can be effectively concentrated at the water outlet 620, thereby improving the power generation efficiency.

[0052] Reference Figure 2 , Figure 3 As shown, according to an optional embodiment, the drain pipe 530 is provided with a mounting portion 510, the mounting portion 510 is provided with a movable platform 130, the water wheel 110 is arranged on the movable platform 130, and the mounting portion 510 is provided with a first driving member 160 to drive the movable platform 130 to move along the central axis side of the drain pipe 530 toward or away from the drain pipe 530. The mounting portion 510 provides an installation space for the water wheel 110, which effectively prevents sewage from leaking to the outside. The movable platform 130 can slide in the mounting portion 510. For example, the chute is provided in one of the mounting portion 510 or the movable platform 130, and the slider is provided in the other, and the two cooperate to enable the movable platform 130 to slide. The water wheel 110 is installed on the movable platform 130, and the water wheel 110 can be moved close to or away from the central axis of the drain pipe 530 by moving the movable platform 130.

[0053] The first driving member 160 can drive the movement of the movable platform 130. For example, the first driving member 160 can be an electric push rod or a cylinder. Since the sewage will be concentrated through the water collecting member 600, when the size of the water outlet 620 changes, the relative position of the water outlet 620 and the water wheel 110 will also change, which may affect the effect of the water flow directly hitting the water wheel 110. Through the movement of the movable platform 130, when the water outlet 620 becomes smaller, the water wheel 110 can be moved to a position close to the center of the drain pipe 530, thereby ensuring that the sewage discharged from the water outlet 620 can better hit the water wheel 110. On the contrary, when the water outlet 620 increases, it means that the amount of sewage increases. By moving the water wheel 110 to a position away from the center of the drain pipe 530, the water wheel 110 can be prevented from blocking the drain pipe 530, thereby maintaining the efficiency of sewage discharge.

[0054] Through this design, the system can generate electricity effectively when there is less sewage, while ensuring rapid discharge when there is more sewage, taking into account both power generation and drainage efficiency.

[0055] Reference Figure 3 , Figure 4 As shown, according to an optional embodiment, the mounting portion 510 includes a closed cavity 511 and a water flow cavity 512, the water flow cavity 512 is connected to the drain pipe 530, the water wheel 110 and the movable platform 130 are located in the water flow cavity 512, the generator 120 is located in the closed cavity 511, the water flow cavity 512 and the closed cavity 511 are sealed and isolated by a partition 520, the water wheel 110 is connected to a rotating shaft 111, and the rotating shaft 111 is driven to rotate when the water wheel 110 rotates; the partition 520 is provided with a connecting hole 521, and the rotating shaft 111 is linked to the generator 120 through the connecting hole 521. Specifically, the rotating shaft 111 passes through the connecting hole 521 on the partition 520, so that the water wheel 110 can drive the generator 120 to work through the rotating shaft 111 when it rotates. In order to adapt to the movement of the water wheel 110, the communication hole 521 is designed as a long strip hole, which provides enough space to ensure the smooth linkage of the rotating shaft 111 during the movement, and prevent sewage from entering the closed chamber 511, thereby ensuring the safe and stable operation of the generator 120. In some solutions, a reduction box 700 is provided between the rotating shaft 111 and the generator 120.

[0056] Reference Figure 3 , Figure 5As shown, according to an optional embodiment, the reduction box 700 includes a first rotating wheel linked to the rotating shaft 111 and a second rotating wheel linked to the generator, the rotating shaft 111 is linked to the generator 120 through the belt 140, the mounting portion 510 is provided with a movable wheel 150 and a second driving member 170, the movable wheel 150 is linked to the belt 140, the movable wheel 150 is movably arranged, and the second driving member 170 is used to drive the movable wheel 150 to move so as to tighten the belt 140. The movable wheel 150 is linked to the belt 140, when the rotating shaft 111 causes the belt 140 to loosen due to the movement of the water wheel 110, the second driving member 170 can drive the movable wheel 150 to move, so as to re-tighten the belt 140, and prevent the loose belt 140 from affecting the normal operation of the generator 120. Exemplarily, the second driving member 170 can adopt a driving structure such as an electric rod or a cylinder to ensure that the belt 140 can always maintain an effective driving force when the position of the water wheel 110 changes. It is understood that the belt 140 is stretched between the first rotating wheel, the second rotating wheel and the movable wheel 150 (refer to Figure 5 shown).

[0057] It is understandable that the first drive member 160 and the second drive member 170 are both electrically connected to the control module 400, so as to realize the linkage control with the power generation module 100. The control module 400 can be intelligently adjusted according to the actual water use situation so that the system can adapt to different water needs. Specifically, the first drive member 160 and the second drive member 170 can be set according to the different situations of the peak water use period and the valley area to optimize the position of the water wheel 110. During the valley period of water use, due to the small amount of water discharge, the system can move the water wheel 110 to the center side of the drain pipe 530 through the first drive member 160 to ensure that the less water flow can still effectively drive the water wheel 110 to generate electricity. During the peak water use period, the water discharge increases, and the system moves the water wheel 110 away from the center side of the drain pipe 530 through the first drive member 160 to avoid the water wheel 110 from obstructing the discharge of sewage, thereby ensuring rapid drainage while still being able to generate electricity efficiently.

[0058] This linkage mechanism not only improves the power generation efficiency, but also ensures the normal operation of the drainage system 500. The control module 400 monitors the drainage situation in real time and dynamically adjusts the position of the water wheel 110, so that the system can perform optimally under different water use conditions. This design makes the entire microgrid energy system more intelligent and efficient, and can achieve energy-saving and consumption-reducing effects in different water use scenarios, effectively reducing the overall energy consumption and carbon emissions of the residential area.

[0059] Reference Figure 3 , Figure 4As shown, according to an optional embodiment, the partition 520 is provided with a sliding plate 522, the sliding plate 522 is rotatably and sealingly connected to the rotating shaft 111, the sliding plate 522 is located at the connecting hole 521 and is used to seal the connecting hole 521, and when the movable platform 130 moves, the sliding plate 522 seals the connecting hole 521. In this way, even when the rotating shaft 111 moves, the sealing of the partition 520 can be ensured, thereby effectively preventing sewage from penetrating into the closed chamber 511 where the generator 120 is located, ensuring that the operating environment of the generator 120 is not affected by sewage.

[0060] Through the above design, not only the efficient linkage between the water wheel 110 and the generator 120 is achieved, but also the flow of sewage in the drain pipe 530 is ensured not to affect the working environment of the generator 120. In addition, by adjusting the positions of the water wheel 110 and the generator 120, the design can adapt to different water flow and drainage conditions, thereby improving the flexibility and reliability of the power generation system. When the drainage volume is large, the system can quickly adjust the position of the water wheel 110 to ensure that the sewage can be discharged quickly, and when the drainage volume is small, the system can also effectively use the limited water flow to generate electricity, thereby maximizing the energy utilization efficiency.

[0061] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
