Description

Technical Field

[0001] The invention relates to the technical field related to new energy, specifically a rainwater power generation and building energy storage peak regulation system. Background Art

[0002] Power grid operations face significant challenges in matching supply and demand: during peak load periods, the system experiences overload pressure, threatening frequency stability; during off-peak periods, redundant generation leads to inefficient energy utilization. This imbalance highlights the urgent need for peak load regulation. While pumped-storage hydropower stations can optimize load distribution, they are expensive and require significant land. This is one of the issues addressed by this invention.

[0003] Buildings are among the largest man-made structures, with vast amounts of roof space resources remaining unused for long periods. Furthermore, roofs are crucial for heat exchange and a vulnerable environment for thermal insulation. In particular, roof waterproofing layers are subject to long-term exposure to high temperatures, wind, solar radiation, and other climatic factors, leading to aging of the waterproofing material and consequently, roof leaks, a common problem in buildings. This is the second problem addressed by this invention.

[0004] One of the main reasons for the slow progress of sponge cities is the high volume of rainwater and the limited capacity of water storage facilities. Many artificial waterscapes lack water due to stagnant water flow, limited water supply, and irrational ecosystem structures, leading to severe water pollution. This is the third problem addressed by this invention. Summary of the Invention

[0005] The purpose of the invention is to provide a rainwater power generation and building energy storage peak regulation system to solve the problems raised in the above background technology. The specific objectives of the invention are as follows:

[0006] (1) Using rooftop water storage can not only solve the problem of heat insulation and cooling of building roofs and protect the waterproof layer, but also increase the storage space of rainwater and solve the problem of water storage and water use in the sponge city strategy.

[0007] (2) Use rainwater to generate electricity and save energy.

[0008] (3) Utilize the high potential energy of rooftop water storage to build a new type of pumped storage power station to meet the peak regulation needs of the power grid.

[0009] To achieve the above objectives, the invention provides the following technical solutions:

[0010] A rainwater-based power generation and building energy storage peak-shaving system includes a water storage roof 1, a water discharge device 2, a rainwater outlet 3, a rainwater gutter 4, a rainwater pipe 5, a power generation device 6, a drainage facility 7, a water storage facility 8, a pumping facility, circuit pipelines 9, and an automatic control device. Roof water on the water storage roof 1 is derived from rainwater and / or pumped water. After being filtered and controlled by the water discharge device 2, it enters the power generation device 6 through the rainwater outlet 3, rainwater gutter 4, and rainwater pipe 5, and finally flows into the water storage facility 8 through the drainage facility 7. The power generation device 6 is fixed to the lower portion of a wall 10, which not only better utilizes the potential energy of the roof water but also facilitates connection to the drainage facility and routine maintenance.

[0011] The controlled water release includes but is not limited to the peak period of power consumption of the power grid, the roof water level is higher than the set value, the water storage roof needs to discharge the roof water, and the water storage facility 8 needs the roof water. The water release device 2 discharges the roof water to meet the needs of power grid peak regulation, hydropower generation, landscape water use and control of water storage weight.

[0012] The pumped water includes water pumped from the water storage facility 8 to the water storage roof when the power consumption of the power grid is low, the water level on the roof is lower than the set value, and the water level of the water storage facility 8 is higher than the set value, so as to meet the needs of low-peak power consumption, power grid peak regulation, roof insulation, rainwater storage, etc.

[0013] The water discharge device 2 is divided into a clean water tank and a drain water tank by an external filter 11 and an internal tank wall 12. The clean water tank communicates with the water storage roof through the filter 11 to filter roof water. The clean water tank communicates with the drain water tank via an inlet 13 and an overflow port 14 to discharge the filtered roof water. The inlet 13 and overflow port 14 are openings in the lower and upper portions of the tank wall 12, respectively. The inlet 13 is also equipped with a gate 15.

[0014] The drainage chamber is provided with a motor 16 at the top to drive the gate plate 15 up and down, and a drain outlet 17 at the bottom to communicate with the rainwater inlet 3. A water level sensor 18 and a roof controller 19 are mounted on both sides of the chamber. The roof controller 19 integrates a temperature sensor, a rainwater sensor, an overload sensor, a motor driver, a control chip, and its supporting circuits, and is electrically connected to the motor 16 and the water level sensor 18 via the circuit pipeline 9.

[0015] The housing of the generator 6 is made of wear-resistant and corrosion-resistant materials and consists of a front housing 20 and a rear housing 21. Both are secured and sealed with screws and sealing strips 22. Semi-flanges at the upper and lower openings of the two housings connect to flanged water inlet and drain ports 23 and 24, respectively. These inlet and drain ports 23 and 24 connect to the stormwater pipe 5 and drainage system 7, respectively. A water inlet pressure sensor 25 is located on the upper portion of the front housing 20, and a drain pressure sensor 26 is located on the lower portion.

The impeller chamber 31, the water inlet port 23, and the drain port 24 intersect at the points where the impeller chamber 31 and the water inlet port 23 and the water outlet port 24 respectively have circular cross-sections of positive pressure chamber 32 and negative pressure chamber 33. The downward portion where the positive pressure chamber 32 and the impeller chamber 31 intersect is a lip wall 34.

[0017] The impeller chamber 31 is equipped with an impeller that matches its cross-sectional shape. The impeller is an integral structure made of wear-resistant and corrosion-resistant materials, consisting of blades 35, a ring 36, a disc 37, and a shaft 38. Bearings and shaft seals are installed at both ends of the shaft 38, and together with the central axial holes of the front and rear housings 20 and 21, they form a rotatable sealed, wear-resistant, and waterproof structure. The shaft 38 is hollow and has a freely rotatable motor shaft 39 mounted in its center. When the blades 35 rotate to the lip wall 34, their direction becomes perpendicular, and together with the lip wall 34, they form a structure that prevents lateral flow of water, thereby preventing water from flowing in the direction opposite to the direction of rotation of the impeller.

[0018] The gear compartment 29 houses a speed-changing gear set 40 connected to the wheel axle 38 and motor shaft 39. The electrical compartment 27 houses a generator 41 and a power generation controller 42, secured to the front housing 20 via screws. The motor shaft 39 of the generator 41 is connected at both ends to bearings located at the center of the gear compartment cover 30 and electrical compartment cover 28. The impeller drives the generator 41 through the speed-changing gear set 40. The speed-changing gears increase the generator's rotor speed.

[0019] The power generation controller 42 is electrically connected to the generator 41, circuit pipeline 9, water inlet pressure sensor 25, and drainage pressure sensor 26, and integrates a generator speed measurement module, temperature and vibration sensors, power management and power detection circuits, a main control chip and its circuits, a communication circuit, and input and output circuits.

[0020] The pumping facility includes a submersible pump 43, a filter box 44, a water pipe 45, a pumping controller 46, a roof water level sensor 47, an in-box water level sensor 48, and an out-box water level sensor 49. The submersible pump 43 is installed in the filter box 44 and is installed at a lower position in the water storage facility 8. The water outlet of the submersible pump 43 is connected to the water pipe 45. The in-box water level sensor 48 and the out-box water level sensor 49 are located inside and outside the filter box 44, respectively. The roof water level sensor 47 is located at a lower position in the water storage roof 1. The submersible pump 43, the in-barrel water level sensor 48, and the out-barrel water level sensor 49 are all electrically connected to the pumping controller 46. The roof water level sensor 47 is electrically connected to the roof controller 19.

[0021] The water storage facility 8 refers to at least one of a water tank, a pool, an artificial water feature, or a natural body of water. The drainage facility 7 refers to a rainwater drain pipe. The automatic control device includes, but is not limited to, an energy conversion and detection module, a battery and its charging and discharging module, a system power management module, an energy output and management module, an internal and external communication module, a control chip and its supporting circuits, and is electrically connected to the roof controller 19, the power generation controller 42, and the pumping controller 46 via the circuit pipeline 9.

[0022] Preferably, the filter screen 11, the bin wall 12, and the gate plate 15 are all made of corrosion-resistant materials.

Shaft 38 is fitted with bearings and seals at both ends, forming a rotatable seal with the central axial holes of the front and rear housings 20 and 21, providing a wear-resistant, waterproof structure. Shaft 38 is hollow, with a freely rotatable motor shaft 39 mounted in its center. When the blades 35 reach the lip 34, their orientation becomes perpendicular, preventing lateral flow.

[0045] Inside the gear compartment 29, a speed-changing gear set 40 is installed, connected to the wheel axle 38 and the motor shaft 39.

The power output and management module is not connected to the mains electricity grid, but only to a self-contained uninterruptible power supply (EPS) to supply electricity to the building. The rest of the system's structure and construction are essentially the same as in Example 1. Water is pumped when electricity prices are low, and released when prices are high to generate electricity. Rainwater is also used for power generation, thus taking advantage of peak and valley electricity prices and rainwater-based power generation to save electricity costs.
