Description

Technical Field

[0001] This invention belongs to the field of hydropower technology, specifically relating to a hydropower generation device based on rain and snow. Background Technology

[0002] In recent years, clean energy power generation technologies such as wind, solar, and hydropower have developed rapidly. Wind power generation uses the flow of air to generate electricity. A wind turbine generator set usually consists of two parts: a wind turbine and a generator. The wind turbine provides the power source for power generation, and the generator converts it into electrical energy. Solar power generation can be divided into two technologies: solar photovoltaic power generation and solar thermal power generation. Photovoltaic power generation uses the photovoltaic effect to generate electricity by shining sunlight onto silicon materials. Solar thermal power generation converts solar energy into thermal energy through heat collection and transfer, and then converts it into electrical energy through a thermodynamic cycle. Hydropower generation uses the mechanical energy of high-level water to convert it into the kinetic energy of low-level water. A hydropower generator set usually consists of two parts: a turbine and a generator. The turbine provides the power source for power generation, and the generator converts it into electrical energy.

[0003] my country is a country with abundant water resources, and its installed hydropower capacity accounts for a relatively high proportion. However, existing hydropower generating units are usually built in mountain valleys, requiring enormous investments. Furthermore, they largely rely on dams and reservoirs to impound water, which not only increases the difficulty of navigation but also inundates ecosystems and alters the landscape. Due to my country's vast territory, annual rainfall and snowfall are also considerable, especially in the southeastern coastal areas. However, these rainfall and snowfall are not fully utilized.

[0004] As is well known, rain and snow resources are unstable, meaning that rainfall and snowfall are uncontrollable and have low energy density. However, due to my country's large urban population, the number of low-rise buildings (such as train station platforms and park pavilions) and high-rise buildings (such as residential buildings, independent commercial buildings, and factory buildings) is considerable. At the same time, the total mileage of my country's highways and high-speed railways is also considerable, and both highways and high-speed railways are laid on viaducts. If all the rain and snow from these low-rise buildings, high-rise buildings, and viaducts were collected, the amount would be quite substantial. Therefore, it is necessary to develop a hydroelectric power generation device that can fully utilize these rain and snow resources and convert them into electricity.

[0005] After searching, three patent documents were found to be most relevant to the technology of this invention, the details of which are described below:

[0006] Patent document CN 201120347406.9 discloses a suspended hydroelectric power generation device, which includes a turbine unit, a generator unit, a float box, a connecting ring, a fixed frame, a drive shaft, a reversing gear, a fixed base, a universal joint, a traction tower, steel cables, and a hydraulic cylinder. The device has a novel design and ingenious concept. The universal joint can not only connect and transmit, but also adjust and eliminate the sway between the turbine units caused by water waves in time to ensure the stable operation of the turbine units. The extension and retraction of the drive shaft can synchronously adjust the rise and fall of the turbine units caused by the rise and fall of the river water level. The device uses the existing river channel to install the turbine directly on the water surface, without the need to build a dam in the river. It has the characteristics of low manufacturing cost and economic and environmental protection. However, the device is only suitable for hydroelectric power generation using natural river channels, and is not suitable for hydroelectric power generation using natural rain and snow.

[0007] Patent document CN 201220395526.0 discloses a pipeline hydroelectric power generation device, which includes a shell, valves, pipes, isolation plates, stator, stator base, rotor, rotor base, shaft, bearings, impeller, disc, blades, blocks, screws, and sealing rings. The device has a novel design and ingenious concept. When the continuous water flow impacts the impeller and rotates half a revolution, it is not immediately discharged, but forms a spiral upward water flow in the lower chamber. It uses its own rotational inertia to drive the impeller to rotate continuously. The impeller can drive the rotor to rotate, thereby generating electricity. The transmission process is relatively simple and avoids energy waste during the transmission process. It has the characteristics of convenient installation, high power generation efficiency, and high energy utilization rate. However, this device is only suitable for hydroelectric power generation using water conservancy pipelines, and is not suitable for hydroelectric power generation using natural rain and snow.

[0008] Patent document CN 201720687298.7 discloses an environmentally friendly hydroelectric power generation device, which includes a water intake channel, valves, a water tank, an overflow trough, an operating platform, a support, a drive shaft, a generator, a water turbine, a water bucket, and an outlet pipe. The device has a novel design and ingenious concept. Water flows from the water source into the water tank through the water intake channel. When the water level reaches a certain height and has a certain potential energy, the valve of the outlet pipe is opened, and the water flows out of the outlet pipe to impact the water bucket, thereby driving the water turbine to rotate. The drive shaft drives the generator to generate electricity. In order to make full use of water resources, as many identical power generation devices as possible are installed downstream, where terrain conditions permit. It has the characteristics of simple structure, easy maintenance, high practicality, and economic and environmental protection. However, this device is only suitable for hydroelectric power generation using natural river channels and is not suitable for hydroelectric power generation using natural rain and snow.

[0062] Example 1: Assembly process of the rain and snow-based hydroelectric power generation device provided by the present invention

[0063] Combination Figures 1 to 27 As shown, the assembly of the device of the present invention is carried out in the following steps:

[0064] Step 1: Assemble the lower support structure

[0065] First, the lower positioning frame 2 is set horizontally. Then, the four first bodies 101 of the four brackets 1 are placed on the second body 201 of the lower positioning frame 2. The sixteen first through holes 103 of the four brackets 1 and the sixteen second through holes 204 of the lower positioning frame 2 are aligned. Then, sixteen first bolts a18 are inserted into the sixteen aligned through holes. Then, sixteen first nuts a19 are screwed onto the sixteen threaded ends of the sixteen first bolts a18 and tightened.

[0066] Step 2: Assemble the core components of the turbine and shaft.

[0067] Then, the locking section 802 of the rotating shaft 8 is inserted into the eighteenth through hole 1303 of the turbine 13. Then, four clamping plates 10 are inserted into the four through slots 804 of the rotating shaft 8. Then, four pads 11 are inserted between the four clamping plates 10. The four screw holes 1101 of the four pads 11 and the eight sixteenth through holes 1001 of the four clamping plates 10 are aligned. Then, eight screws 15 are passed through the eight sixteenth through holes 1001 and screwed into the four screw holes 1101 and tightened.

[0068] Step 3: Install the lower rolling bearing and water-retaining ring.

[0069] Then, a rolling bearing 17 is installed in the first groove 206 of the lower positioning frame 2. Then, the assembly of the rotating shaft 8 and the turbine 13, which has completed step two, is lifted vertically, and the second bearing section 803 of the rotating shaft 8 is inserted into the inner ring of the rolling bearing 17 from above. Then, the water baffle ring 12 is lifted vertically, passed through the assembly of the rotating shaft 8 and the turbine 13 from above, and inserted into the third boss 203 of the lower positioning frame 2.

[0070] Step 4: Install the upper rolling bearing and the upper positioning frame.

[0071] Then, another rolling bearing 17 is installed in the second groove 307 of the upper positioning frame 3. The upper positioning frame 3 is then slipped off from above the rotating shaft 8, and the first bearing section 801 of the rotating shaft 8 is inserted into the inner ring of the rolling bearing 17 from below. At the same time, the sixth boss 304 of the upper positioning frame 3 is inserted from above into the seventeenth through hole 1201 of the water baffle ring 12 until the lower end face of the third body 301 of the upper positioning frame 3 can contact the upper end face of the water baffle ring 12. At this time, the inner wall of the water baffle ring 12 and the outer wall of the sixth boss 304 form a fit.

[0072] Step 5: Connect the drive shaft to the generator shaft

[0073] Then, two keys 14 are installed in the two sixth grooves 805 of the rotating shaft 8. Then, one of the couplings 9 is inverted, that is, the ninth boss 902 is located below the sixth body 901. Then, the end of the first bearing section 801 of the rotating shaft 8 is inserted from below into the fourteenth through hole 903 of the coupling 9. At the same time, the two keys 14 installed in the two sixth grooves 805 of the rotating shaft 8 are inserted into the two seventh grooves 905 of the coupling 9.

[0074] Then, install two more keys 14 in the two eighth grooves 1601 of the shaft 16, and then position the other coupling 9 upright, that is, the ninth boss 902 is located above the sixth body 901. Since the upper part of the shaft 16 passes through the twelfth through hole 604 of the generator 6, then lift the generator 6 vertically and keep it in the standard upright position. Then, the lower part of the shaft 16 passes through the fourteenth through hole 903 of the coupling 9 from above. At the same time, the two keys 14 installed in the two eighth grooves 1601 of the shaft 16 are passed through the two seventh grooves 905 of the coupling 9.

[0075] Then, the lower end face of the sixth body 601 of the upright coupling 9 and the upper end face of the sixth body 601 of the inverted coupling 9 are aligned. Then, the turbine 13 is slowly rotated to align the four fifteenth through holes 904 of the upright coupling 9 and the four fifteenth through holes 904 of the inverted coupling 9. Then, four second bolts b18 are inserted into the four sets of aligned through holes. Then, four second nuts b19 are screwed onto the four threaded ends of the four second bolts b18 and tightened.

[0076] Step Six: Install water pipes and roof slab

[0077] Then, n water pipes 4 are inserted into the n fourth protrusions 302 of the upper positioning frame 3. Then, a top plate 5 is placed on the four first bodies 101 of the four supports 1. At the same time, the upper end face of the fourth body 601 of the generator 6 can contact the lower end face of the top plate 5. Then, the sixteen tenth through holes 505 of the top plate 5 and the sixteen first through holes 103 of the four supports 1 are aligned. Then, sixteen first bolts a18 are inserted into the sixteen aligned through holes. Then, sixteen first nuts a19 are screwed onto the sixteen threaded ends of the sixteen first bolts a18 and tightened. At this time, the sixteen heads of the sixteen first bolts a18 are all submerged in the sixteen fourth grooves 504 of the top plate 5.

[0078] Step 7: Install the generator

[0079] Since the generator 6 is always in a standard upright position, the four side end faces of the fourth body 601 of the generator 6 and the four side end faces of the top plate 5 are parallel to each other. At this time, the four eleventh through holes 603 of the generator 6 and the four ninth through holes 503 of the top plate 5 are aligned. Then, four first bolts a18 are inserted into the four sets of aligned through holes, and four first nuts a19 are screwed onto the four threaded ends of the four first bolts a18 and tightened. At this time, the four heads of the four first bolts a18 are all submerged in the four third grooves 502 of the top plate 5.

[0080] Step 8: Install the water collection frame

[0081] Finally, the n eighth protrusions 702 of the water collection frame 7 are sequentially passed through the n eighth through holes 501 of the top plate 5 and inserted into the n seventh through holes 401 of the n water supply pipes 4 until the lower end face of the fifth body 701 of the water collection frame 7 can contact the upper end face of the top plate 5. At this time, the n eighth protrusions 702 of the water collection frame 7 can cooperate with the n eighth through holes 501 of the top plate 5 and the n seventh through holes 401 of the n water supply pipes 4.

[0082] Example 2: Working principle of the rain and snow-based hydroelectric power generation device provided by the present invention

[0083] During the rainy season, rainwater can be collected over a large area within the fifth groove 703 of the water collection frame 7. The rainwater flows into the seventh through hole 401 of the water supply pipe 4 through the thirteenth through hole 704 of the water collection frame 7. The rainwater falls vertically onto the blades 1302 of the turbine 13 through the sixth through hole 306 of the upper positioning frame 3, thereby driving the turbine 13 to rotate. In turn, the turbine 13 rotates through the coupling 9, causing the machine shaft 16 to rotate and the generator 6 to start generating electricity. The rainwater is discharged through the third through hole 205 of the lower positioning frame 2.

[0084] Snowflakes can be collected over a large area in the fifth groove 703 of the water collection frame 7 during the snow season. After the snowflakes melt, they become snow water. The snow water flows into the seventh through hole 401 of the water supply pipe 4 through the thirteenth through hole 704 of the water collection frame 7. The snow water falls vertically onto the blades 1302 of the turbine 13 through the sixth through hole 306 of the upper positioning frame 3, thereby driving the turbine 13 to rotate. In turn, the turbine 13 rotates through the coupling 9, and the generator 6 starts generating electricity. The snow water is discharged through the third through hole 205 of the lower positioning frame 2.

[0085] Water collected at a high altitude falls vertically onto the blades 1302 of the turbine 13. The potential energy of the water is first converted into the kinetic energy of the water, thereby driving the blades 1302 to rotate. Since the power generation depends on the potential energy of the water, and the opening area of ​​the fifth groove 703 of the water collection frame 7 and the length of the water supply pipe 4 determine the potential energy of the water, the opening area of ​​the fifth groove 703 of the water collection frame 7 and the length of the water supply pipe 4 should be increased. In addition, according to the size of the space, multiple specifications of the device of the present invention should be designed and manufactured to match it.

[0086] Since the height of low-rise buildings is usually between 3000mm and 5000mm, the height of elevated bridges is usually between 5000mm and 20000mm, and the height of high-rise buildings is usually between 20000mm and 100000mm, the head difference between low-rise buildings, elevated bridges and high-rise buildings is usually between 3000mm and 100000mm. And since water flows into the multiple blades 1302 of turbine 13 along the axial direction and flows out along the axial direction, an axial-flow turbine is selected for the water turbine, and a vertical turbine generator is selected accordingly.

[0087] Example 3: The rain and snow-based hydroelectric power generation device provided by the present invention used alone.

[0088] The rain and snow-based hydroelectric power generation device provided by this invention is horizontally installed on an open-air platform, which should be 500mm above the ground. In order to maximize the potential energy of the water, the opening area of ​​the fifth groove 703 of the water collection frame 7 and the length of the water supply pipe 4 should be maximized. At the same time, the opening depth of the fifth groove 703 of the water collection frame 7 should be appropriately increased to increase the water storage capacity of the fifth groove 703 of the water collection frame 7. Taking all factors into consideration, the optimal opening length of the fifth groove 703 of the water collection frame 7 is 25000mm, the opening width is 16000mm, and the opening depth is 300mm. The optimal length of the water supply pipe 4 is 20000mm and the inner diameter is 100mm.

[0089] The water turbine is an axial flow water turbine, and the generator is a vertical water turbine generator; in this embodiment, n is 2, and the corresponding number of water pipes 4 is two, the number of third through holes 205 of the lower positioning frame 2 is two, the number of fourth protrusions 302 of the upper positioning frame 3 is two, the number of eighth through holes 501 of the top plate 5 is two, and the number of eighth protrusions 702 of the water collecting frame 7 is two.

[0090] When it rains in the area, the fifth groove 703 of the water collection frame 7 can collect rainwater over a large area. The rainwater flows into the seventh through hole 401 of the water supply pipe 4 through the thirteenth through hole 704 of the water collection frame 7. The rainwater falls vertically onto the blades 1302 of the turbine 13 through the sixth through hole 306 of the upper positioning frame 3, thereby driving the turbine 13 to rotate. In turn, the turbine 13 rotates through the coupling 9, and the generator 6 starts generating electricity. The rainwater is discharged through the third through hole 205 of the lower positioning frame 2.

[0091] When it snows in the area, the fifth groove 703 of the water collection frame 7 can collect snowflakes over a large area. After the snowflakes melt, they become snow water. The snow water flows into the seventh through hole 401 of the water supply pipe 4 through the thirteenth through hole 704 of the water collection frame 7. The snow water falls vertically onto the blades 1302 of the turbine 13 through the sixth through hole 306 of the upper positioning frame 3, thereby driving the turbine 13 to rotate. In turn, the turbine 13 rotates through the coupling 9, and the generator 6 starts generating electricity. The snow water is discharged through the third through hole 205 of the lower positioning frame 2.

The rain and snow-based hydroelectric power generation device provided by this invention is horizontally installed on a platform. The platform should be directly opposite the lowest point of the corner or edge of the low-rise building and should be 500mm above the ground. Since the opening area of ​​the fifth groove 703 of the water collection frame 7 is not significant for increasing the water's potential energy, the length of the water delivery pipe 4 should be maximized to increase the water's potential energy as much as possible. Considering all factors, the optimal opening length of the fifth groove 703 of the water collection frame 7 is 1000mm, the opening width is 1000mm, and the opening depth is 100mm. The optimal length of the water delivery pipe 4 is the height of the low-rise building minus 2000mm, and the inner diameter is 100mm.

In turn, the turbine 13 rotates through the coupling 9, which drives the shaft 16 to rotate, and the generator 6 starts generating electricity. The snow water is discharged through the third through hole 205 of the lower positioning frame 2.

Since the opening area of ​​the fifth groove 703 of the water collection frame 7 is not significant for increasing the potential energy of the water, in order to increase the potential energy of the water as much as possible, the length of the riser of the water collection pipe of the high-rise building should be shortened as much as possible in order to increase the length of the water delivery pipe 4. Taking all factors into consideration, the optimal opening length of the fifth groove 703 of the water collection frame 7 is 1000mm, the opening width is 1000mm, and the opening depth is 100mm.

The platform should be directly opposite the riser of the elevated bridge's water collection pipe and should be 500mm above the ground. Since the opening area of ​​the fifth groove 703 of the water collection frame 7 is not significant for increasing the potential energy of the water, in order to increase the potential energy of the water as much as possible, the length of the riser of the elevated bridge's water collection pipe should be shortened as much as possible to increase the length of the water delivery pipe 4.

[0107] Example 7: Grid connection operation of a single rain and snow-based hydroelectric power generation device provided by the present invention with a nearby power grid.

[0108] When only one rain and snow-based hydroelectric power generation device provided by this invention is working alone, the situation is relatively simple; grid connection of a single device of this invention is to close the circuit breaker at the nearby power grid access point, connecting the single device of this invention to the nearby power grid.

[0109] The conditions for grid connection of a single device of this invention are as follows: the phase sequence of the three-phase AC power output by the single device of this invention should be consistent with the phase sequence of the nearby power grid; the voltage of the three-phase AC power output by the single device of this invention should be equal to the voltage of the nearby power grid, and the voltage difference between the two should be controlled within ±5% of the rated voltage; the frequency of the three-phase AC power output by the single device of this invention should be the same as the frequency of the nearby power grid. The standard frequency of the power grid in my country is 50Hz, and the frequency difference between the two should be controlled within ±0.2Hz; the phase of the three-phase AC power output by the single device of this invention should be similar to the phase of the nearby power grid, and the phase difference between the two should be controlled within a certain angle range.

[0110] Preparations for grid connection of a single device of this invention: Ensure that the single device of this invention and its auxiliary equipment are in normal operating condition, without faults or abnormalities. Check whether the phase sequence of the three-phase AC power output by the single device of this invention is consistent with the phase sequence of the nearby power grid using tools such as a phase sequence table. Adjust the speed of the single device of this invention using a speed controller to make it close to the speed corresponding to the nearby power grid. Check and engage the excitation section of the single device of this invention to ensure that it outputs a suitable excitation current and establishes a suitable magnetic field. Adjust the voltage of the output three-phase AC power. Since the voltage of the three-phase AC power output by the single device of this invention is much lower than the voltage of the nearby power grid, step up the voltage using a transformer.

[0111] Operation of a single device of the present invention connected to the grid: When the speed, voltage and frequency of a single device of the present invention are close to the grid connection conditions, the phase difference, frequency difference and voltage difference between the single device of the present invention and the nearby power grid are detected by a synchronizing device; when the phase difference, frequency difference and voltage difference all meet the requirements, the operator manually or automatically closes the circuit breaker at the generator outlet to connect the single device of the present invention to the nearby power grid and continuously transmit the electrical energy generated by the single device of the present invention.

[0112] Example 8: Grid connection operation of multiple rain and snow-based hydropower generation devices provided by the present invention and nearby power grids.

[0113] When multiple devices of the present invention are working together, the situation is relatively complicated and requires the use of a combiner box to collect the output current of multiple devices of the present invention; grid connection of multiple devices of the present invention involves closing the circuit breaker at the nearby power grid access point to connect multiple devices of the present invention to the nearby power grid.

[0114] Conditions for grid connection of multiple devices of this invention: When using a combiner box for grid connection, since the wiring and equipment connection in the early stage are carried out in accordance with relevant technical standards and specifications, the phase sequence of the three-phase AC power output from the combiner box must be consistent with the phase sequence of the nearby power grid; the voltage of the three-phase AC power output from the combiner box should be equal to the voltage of the nearby power grid, otherwise a large inrush current will be generated at the moment of grid connection; the frequency of the three-phase AC power output from the combiner box should be the same as the frequency of the nearby power grid, otherwise power oscillation will occur between multiple devices of this invention and the nearby power grid; at the moment the circuit breaker is closed, the phase of the three-phase AC power output from the combiner box should be the same as the phase of the nearby power grid, that is, the phase angle difference should be zero, otherwise a large inrush current will be generated during grid connection;

[0115] Preparations for grid connection of multiple devices of this invention: Ensure that each device of this invention and its auxiliary equipment are in normal operating condition and that their performance parameters meet the requirements; check the combiner box to ensure that its internal protection system and detection system are working properly, and that the wiring is secure; connect the output terminal of the combiner box to the access point of the nearby power grid through a suitable cable and circuit breaker; adjust the output voltage and frequency of each device of this invention to make the frequency close to the standard value of the nearby power grid, and step up the voltage through a transformer to make the voltage close to the standard value of the nearby power grid; use a synchronization device to check the consistency of the voltage, frequency, and phase of the combiner box output terminal with the voltage, frequency, and phase of the nearby power grid;

[0116] Operation of multiple devices of the present invention connected to the grid: When the voltage, frequency and phase of the three-phase AC power output from the combiner box are the same as the voltage, frequency and phase of the nearby power grid, that is, when the synchronization conditions are met, the operator manually or automatically closes the circuit breaker at the nearby power grid connection point to connect multiple devices of the present invention to the nearby power grid, and continuously transmits the electrical energy generated by multiple devices of the present invention.

[0117] Example 9: Technical Measures for Improving Unit Stability of Rain and Snow-Based Hydropower Generation Devices Provided by the Invention

[0118] Although rainfall and snowfall are subject to unstable factors, each rainfall or snowfall event typically lasts for several hours. Given that my country's total building area is approximately 80 billion square meters, highways approximately 2.5 billion square meters, and high-speed railways approximately 500 million square meters, the collected rainwater and the device of this invention can generate electricity for several hours during a rainfall event, making the power generation from rainfall events quite considerable. Similarly, during snowfall events lasting several hours, the collected melted snowflakes and the device of this invention can also generate electricity for several hours, making the power generation from snow melting events quite considerable, although there is a lag compared to rainfall events.

[0119] The technical measures of this invention to improve unit stability include: optimizing turbine design to ensure a reasonable turbine structure, reducing energy loss and mechanical wear; selecting appropriate turbine shape, number of blades, and turbine speed to adapt to different head heights and flow conditions; accurately monitoring local rainfall and snowfall amounts and durations with the help of meteorological departments to promptly activate the device and adjust its operating parameters to adapt to different head storage and flow conditions; using high-quality materials and advanced manufacturing processes to ensure the quality and precision of the power generation equipment; adhering to relevant technical standards and specifications during installation to ensure installation accuracy and connection reliability; developing and using an advanced automated control system capable of real-time monitoring and adjustment of the device's operating status, such as turbine speed and power output, to respond promptly to flow conditions and load fluctuations; formulating a scientific and standardized maintenance plan to regularly conduct comprehensive inspections, maintenance, and repairs, promptly replacing worn or failed parts to ensure the equipment is always in good operating condition; optimizing the connection method with the nearby power grid to improve the stability and compatibility of power output, minimizing impact and interference to the nearby power grid; and strengthening personnel training to improve the technical level and emergency response capabilities of operators.

[0120] Example 10: Energy storage technology for rain and snow-based hydropower generation devices when used alone, as provided by the present invention.

[0121] When the device of the present invention is used alone, since the opening area of ​​the fifth groove 703 of the water collection frame 7 is much larger than the optimal inner diameter of the water supply pipe 4, and the fifth groove 703 of the water collection frame 7 has a certain opening depth, during continuous rainfall, the fifth groove 703 of the water collection frame 7 can both continuously collect a large amount of rainwater and dynamically store a large amount of rainwater; similarly, during continuous snowfall, the fifth groove 703 of the water collection frame 7 can both continuously collect a large amount of snowflakes and store a large amount of snowflakes. Depending on the available space, the opening area and opening depth of the fifth groove 703 of the water collection frame 7 should be maximized to maximize the energy storage capacity of the fifth groove 703, and the number of water supply pipes 4 used should be minimized to extend the continuous working time of the device of the present invention as much as possible.

[0122] In summary, the energy storage technology of Example 10 only increases the manufacturing cost of the device of the present invention, but it can increase the potential energy of rainwater or snow water. In this way, it saves the number of water pipes 4 used and extends the working time of the device of the present invention.

[0123] Example 11: Energy storage technology provided by the present invention for use in conjunction with rain and snow hydropower generation devices and low-rise buildings.

[0124] Since low-rise buildings such as station platforms and park pavilions usually lack water collection pipes and their tops are not typically flat, the edges of the tops of station platforms and park pavilions can be uniformly raised by 300mm to 500mm with cement to form a high-level water storage tank with a closed perimeter. This creates a high-level water storage tank with water storage function, and waterproofing is ensured. Since each stream of water is equipped with one device of this invention, only one drainage hole needs to be opened at an appropriate location at the bottom of the high-level water storage tank. This allows multiple streams of water to be combined into one stream, thus requiring only one device of this invention to complete the entire power generation task, effectively extending the working time of one device of this invention several times over.

[0125] In summary, the energy storage technology of Example 11 only increases the construction cost of the high-level reservoir, while the potential energy of rainwater or snowmelt is not lost. In this way, the number of devices used in this invention is reduced, and the working time of the device is extended.

[0126] Example 12: Energy storage technology for rain and snow-based hydropower generation devices used in conjunction with high-rise buildings, as provided by the present invention.

[0127] Since high-rise buildings such as residential buildings, independent commercial buildings, and factory buildings usually have water collection pipes and their tops are usually relatively flat, the edges of the tops of residential buildings, independent commercial buildings, and factory buildings can be uniformly raised by 300mm to 500mm with cement to form a high-level water storage tank with a closed perimeter. That is, a high-level water storage tank with water storage function is constructed, and waterproofing is done. Since one device of the present invention is configured for each water flow, only one drainage hole in an appropriate position is left open, and a sealing plug is inserted into the remaining drainage holes. In this way, the original multiple water flows can be gathered into one water flow. Thus, only one device of the present invention is needed to complete the entire power generation task, which is equivalent to extending the working time of one device of the present invention several times.

[0128] In summary, the energy storage technology of Example 12 only increases the construction cost of the high-level reservoir, while the potential energy of rainwater or snowmelt is not lost. In this way, the number of devices used in this invention is reduced, and the working time of the device is extended.

[0129] Example 13: Energy storage technology for rain and snow-based hydropower generation devices and viaducts provided by the present invention.

[0130] Since water accumulation is not permitted on highways and high-speed railways, a rectangular elevated water storage tank is constructed directly beneath the viaduct deck, opposite the viaduct's water collection pipe riser. The opening length of the elevated water storage tank should be slightly shorter than the bridge length, the opening width should be one-third of the bridge width, and the opening depth should be 600mm. Waterproofing is also ensured. Since each stream of water is equipped with one device of this invention, a limited number of drainage holes are evenly opened at appropriate locations at the bottom of the elevated water storage tank. This allows the originally infinite number of water streams to be collected into a limited number of streams. As a result, only a limited number of devices of this invention are needed to complete the entire power generation task, effectively extending the working time of the limited number of devices of this invention several times over.

[0131] In summary, the energy storage technology of Example 13 only increases the construction cost of the high-level reservoir. Although there will be a small loss of potential energy from rainwater or snowmelt, the overall gains outweigh the losses. It saves on the number of devices to be used and extends the working time of the devices.

[0132] In summary, as can be seen from Examples 1 to 13, the hydroelectric power generation device based on rain and snow provided by the present invention can achieve the purpose of collecting a large amount of rainwater or snowflakes and converting their high potential energy into electrical energy. The device of the present invention has the characteristics of low manufacturing cost and good performance.

[0133] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
