Description

Technical Field

[0001] The utility model relates to the technical field of power generation equipment, and in particular, to a water-based power generation low-valley electricity storage conversion device. Background Art

[0002] The load of the power system is always changing. For example, peak loads may occur in the morning and at dusk, while the period from 10 pm to 6 am may be a low-valley area of the load. In order to flatten the peak of the power system, fill the low valley, promote the planned power consumption and power saving of users, and give full play to the economic leverage of prices, a peak-valley electricity price system can be implemented. The electricity-consuming units during peak electricity consumption are relatively concentrated, and the electricity charge standard is higher when the power supply is tense. The electricity-consuming units during low-valley electricity consumption are fewer and the power supply is relatively sufficient, and the electricity charge standard is lower. Implementing peak-valley electricity prices can give full play to the economic leverage of prices, mobilize the enthusiasm of users to cut peaks and fill valleys and balance power consumption. The application of peak-valley electricity prices alleviates the contradiction between power supply and demand, improves the grid load rate and equipment utilization rate, and is conducive to prompting electricity-consuming units to stagger their power consumption times and make full use of equipment and energy.

[0003] For power plants, the electricity consumption during peak electricity consumption is extremely large. When holding large-scale events or other special situations, there may even be an overload of electricity consumption, resulting in a shortage of power generation. While during low-valley electricity consumption, the electricity consumption is less, and the power generation will have a surplus, causing waste. Therefore, the utility model provides a water-based power generation low-valley electricity storage conversion device, which stores the surplus power generation during low-valley electricity consumption with a lower charge and releases the stored power during peak electricity consumption with a higher charge. This not only alleviates the situation of tight electricity consumption during peak electricity consumption, but also charges the surplus power generation during low-valley electricity consumption at the standard of peak electricity consumption, improving the power supply during peak electricity consumption and thus increasing economic benefits.

Additionally, all embodiments may be used in combination with each other.

[0030] Embodiment 1:

[0031] Hydrogen energy storage is an important part of new energy storage. Hydrogen energy storage is efficient, clean, and sustainable. At the same time, as a carbon-free energy storage technology, it is an extension of chemical energy storage. Compared with other energy storage mechanisms, hydrogen energy storage has a high energy density, low operation and maintenance costs, a long storage time, no pollution, and good environmental compatibility. The power and energy of hydrogen energy storage can be independently optimized, and the electricity storage and power generation processes do not require time-sharing operation. It is an ideal green energy storage technology.

[0032] The hydrogen energy storage system is an "electricity - hydrogen - electricity" conversion, which means converting distributed renewable energy electricity or the excess electricity in the power grid into the chemical energy of hydrogen through electrolytic water hydrogen production, and then using hydrogen power generation technology to convert hydrogen energy back into electricity and transmit it back to the power grid, or transport it to the user side for distributed power generation, usually limited to applications in the power generation field. Hydrogen energy storage technology is a large-scale energy storage technology with great development potential, and this technology can be used in many scenarios such as peak shaving and frequency modulation, load shifting of the power grid, combined cooling, heating, and power supply for users, and microgrids.

[0033] A device for converting and storing electricity during low - power periods of water - based power generation includes a floating deck 1. A generator set 2 is arranged on the floating deck 1. A main pulley 3 is connected to the generator set 2. An auxiliary sliding component is also arranged on the floating deck 1. An operating cable 4 is rotatably connected to the main pulley 3. The operating cable 4 is connected to the auxiliary sliding component and the main pulley 3. Two floating counterweight balls 5 that move in water are arranged on the operating cable 4. A gas storage and generation device 6 for generating, storing, and discharging gas is connected to the upper surface of the floating deck 1. The gas storage and generation device 6 is connected to both of the two floating counterweight balls 5 through air pipes 7. Each floating counterweight ball 5 has a hemispherical cavity 10 and a hemispherical counterweight 11. The hemispherical counterweight 11 is arranged in the lower half of the floating counterweight ball 5. The hemispherical cavity 10 fills the upper half of the floating counterweight ball 5. At least one water - passing hole 9 communicating with the outside is opened in the hemispherical counterweight 11. The air pipe 7 is connected to the hemispherical cavity 10.

[0034] The auxiliary sliding member includes two upper pulleys 12 and two lower pulleys 13. The two upper pulleys 12 are rotatably arranged on both sides of the upper surface of the floating deck 1. The two lower pulleys 13 are arranged below the water surface and on both sides of the floating deck 1. The operating cable 4 is wound around the periphery of the main pulley 3, the two upper pulleys 12 and the two lower pulleys 13. The two floating counterweight balls 5 are respectively arranged between the upper pulley 12 and the lower pulley 13 on the same side.

[0035] A net cage 29 for aquaculture is also arranged below the floating deck 1. Various aquatic products can be cultured by using the net cage 29, which can increase the functionality of the device and meet different usage requirements.

[0036] During use, the two upper pulleys 12 are placed above the floating deck 1, and the two lower pulleys 13 are fixed in the water. Hydrogen can be produced and stored in the gas storage and power generation device 6 during the low - electricity - consumption period through wind power generation and photovoltaic power generation. Other gases insoluble in water can also be stored in the gas storage and power generation device 6. When the electricity consumption is high, gas is filled into the hemispherical cavity of one of the floating counterweight balls 5 through the gas storage and power generation device 6. The water in the floating counterweight ball 5 filled with gas is gradually squeezed out, and its buoyancy slowly increases. When the buoyancy is greater than the difference between the gravity of the floating counterweight ball 5 filled with water and the gravity of the floating counterweight ball 5 without water entering, the floating counterweight ball 5 filled with gas gradually rises, and the other floating counterweight ball filled with water gradually falls, driving the operating cable 4 to rotate on the main pulley 3, the upper pulley 12 and the lower pulley 13. Then, by pumping out the gas in the floating counterweight ball 5 filled with gas and filling gas into the other floating counterweight ball 5 without gas, the two floating counterweight balls 5 can move up and down in a cycle. Then, through the generator set 2, the kinetic energy is converted into electric energy, so that the remaining generated electricity during the low - electricity - consumption period with a lower charge can be used in the high - electricity - consumption period in the form of electricity - gas - electricity. This measure not only alleviates the situation of tight electricity consumption during the high - electricity - consumption period, but also charges the remaining generated electricity during the low - electricity - consumption period at the standard of high - electricity - consumption, improving the power supply during the high - electricity - consumption period and thus enhancing the economic benefits.

[0037] The generator set 2 includes a speed increaser, a generator and a controller. It is connected to the main pulley 3 through the speed increaser, generates electricity through the generator, and then sends the generated electricity through the controller.

[0038] Embodiment 2:

[0039] Except for the following different technical features described, the rest of the technical features identical to those in Embodiment 1 will not be elaborated here.

[0040] The auxiliary sliding member includes a lower pulley 13, which is rotatably connected below the floating deck 1. The operating cable 4 is rotatably wound around the outside of the main pulley 3 and the lower pulley 13. Two floating counterweight balls 5 are respectively arranged on the operating cable 4 on both sides of the main pulley 3. Two rotating wheels 8 that cooperate with the ventilation pipes 7 are rotatably connected to the floating deck 1. Each ventilation pipe 7 rotates with the rotating wheel 8 to inflate the two floating counterweight balls 5.

[0041] During use, the lower pulley 13 is fixed in the water. The operating cable 4 is sleeved and rotated between the main pulley 3 and the lower pulley 13. Two floating counterweight balls 5 are respectively arranged on the operating cable 4 on both sides of the main pulley 3. By means of the main pulley 3 and the lower pulley 13, the operation of driving the generator by rotating the cable can be completed. This setting can be used in combination with different water areas and different power generation scenarios.

[0042] Embodiment 3:

[0043] Except for the following described distinguishing technical features, the other technical features that are the same as those in Embodiment 1 will not be elaborated here.

[0044] The auxiliary sliding member includes two upper pulleys 12, which are rotatably arranged on both sides of the upper surface of the floating deck 1. Two floating counterweight balls 5 are respectively connected to the two ends of the operating cable 4. The two floating counterweight balls 5 are placed on the two upper pulleys 12 through the operating cable 4. The operating cable 4 is rotatably connected above the main pulley 3 and the upper pulley 12. By this setting method, two buoyancy counterweight balls can be directly placed on the floating deck 1 without fixing other pulleys in the water, which is convenient for erection and has a flexible application scenario. And air can be directly filled into the buoyancy counterweight balls and then directly discharged. Whether to produce hydrogen and other gases for closed storage can be selected according to needs, reducing the complexity of the device.

[0045] It also includes two groups of exhaust blocks 14 and air inlet nozzles 17 vertically arranged in the water. Each air inlet nozzle 17 is communicated with the ventilation pipe 7. Each floating counterweight ball 5 is provided with a ventilation and discharge pipe 15 and two ventilation and discharge fasteners 16. A trapezoidal air inlet hole 18 that communicates the hemispherical cavity 10 with the outside is opened on the hemispherical counterweight member 11. The air inlet nozzle 17 is movably arranged in the trapezoidal air inlet hole 18. Ventilation holes 19 are opened on both ventilation and discharge fasteners 16. The ventilation and discharge pipe 15 is inserted into the trapezoidal air inlet hole 18 and is located inside the hemispherical cavity 10. The two ventilation and discharge fasteners 16 are movably sleeved on the ventilation and discharge pipe 15. The two ventilation and discharge fasteners 16 are respectively fixedly connected to the inner side wall of the trapezoidal air inlet hole 18 and the inner top of the hemispherical cavity 10. Control components are provided at both ends of the ventilation and discharge pipe 15, and the control components are used to control the gas to enter the ventilation holes 19 for inflation and exhaust. A plurality of inflation holes 20 are opened in the middle of the ventilation and discharge pipe 15. The exhaust block 14 can be abutted against the top end of the ventilation and discharge pipe 15.

[0046] The inside of the through - exhaust pipe 15 is hollow, and one end close to the air inlet nozzle 17 penetrates through the through - exhaust pipe 15. Two control grooves perpendicular to its length direction are opened on the through - exhaust pipe 15. The inflation hole 20 and the control grooves are both connected to the inside of the exhaust pipe. The control component includes a connecting spring 22 and two communicating blocks 23. The two communicating blocks 23 are respectively fixedly connected to both ends of the connecting spring 22. The communicating block 23 is movably connected in the corresponding control groove. A communicating groove 24 adapted to the corresponding communicating block 23 is opened on the through - exhaust fixture 16. The ventilation hole 19 is connected to the inside of the through - exhaust pipe 15 through the communicating groove 24 and the communicating block 23.

[0047] The air inlet nozzle 17 includes a trapezoidal tower shell 25 and a control ball 26. The trapezoidal tower shell 25 is hollow with both ends open. A support column 27 is vertically arranged at the bottom inside the trapezoidal tower. A telescopic spring 28 is fixedly connected to the support column 27. The control ball 26 is fixedly connected to the end of the telescopic spring 28 away from the support column 27. The ventilation pipe 7 communicates with the bottom of the trapezoidal tower shell 25. The control ball 26 is movably clamped at the top of the trapezoidal tower shell 25 and is in movable contact with the bottom of the through - exhaust pipe 15. The trapezoidal tower shell 25 is movably arranged in the trapezoidal air inlet hole 18.

[0048] When this embodiment is in use, place the two upper pulleys 12 above the floating deck 1. Lay the operation cable 4 with floating counterweight balls 5 connected at both ends on the two upper pulleys 12 and the main pulley 3. Place the two floating counterweight balls 5 in the water. Fix the exhaust block 14 and the air inlet nozzle 17 at appropriate positions. Cooperate one of the floating counterweight balls 5 with an air inlet nozzle 17 so that the air inlet nozzle 17 is inserted into the trapezoidal air inlet hole 18. The lower communicating block 23 extends out of the control groove and is placed in the communicating groove 24. At this time, the lower end of the exhaust - through pipe abuts against the control ball 26, driving the control ball 26 to move downward and compress the telescopic spring 28, so that the gas introduced into the ventilation pipe 7 can enter the through - exhaust pipe 15 through the pore generated by the downward movement of the control ball 26 at the upper end of the trapezoidal tower shell 25. The introduced gas can enter the hemispherical cavity 10 through the inflation hole 20 in the middle of the through - exhaust pipe 15 and the ventilation hole 19 located in the trapezoidal air inlet hole 18. At the same time, the upper communicating block 23 is pushed by the extrusion and is pushed into the corresponding control groove. At this time, the gas introduced from the ventilation pipe 7 is blocked in the exhaust - through pipe and cannot be discharged through the ventilation hole 19 on the through - exhaust fixture 16 in the hemispherical cavity 10. Thus, the gas can be filled into the hemispherical cavity 10;

[0049] The water in the floating counterweight ball 5 filled with gas is gradually squeezed out from the water - through hole 9, and its buoyancy slowly increases. When the buoyancy is greater than the difference between the gravity of the floating counterweight ball 5 filled with water and the gravity of the floating counterweight ball 5 without water entering, the floating counterweight ball 5 filled with gas gradually rises, and the other water - filled counterweight ball gradually falls, driving the operation cable 4 to rotate on the main pulley 3 and the lower pulley 13.

[0050] When the ascending floating counterweight ball 5 reaches the position of the exhaust block 14, the upper end of the exhaust and vent pipe 15 abuts against the exhaust block 14, and the exhaust block 14 pushes the exhaust and vent pipe 15 to insert into the floating counterweight ball 5. At this time, the connecting block 23 located in the communication groove 24 of the trapezoidal intake hole 18 is squeezed and pushed into the corresponding control groove. At this time, the gas introduced from the vent pipe 7 is blocked in the exhaust and vent pipe and cannot continue to enter the hemispherical cavity 10. And the connecting block 23 located above extends out of the control groove and is placed in the communication groove 24, so that the hemispherical cavity 10 can be connected to the outside through the vent hole 19, thereby discharging the gas filled into the hemispherical cavity 10, reducing the buoyancy. After the buoyancy is greater than the critical value, the up-and-down cyclic movement of the two floating counterweight balls 5 is realized, driving the operation cable 4 and the main pulley 3 to rotate, and then converting the kinetic energy into electric energy through the generator set 2, so that the remaining generated electricity during the low-valley power consumption with lower charges can be used in the form of electricity-gas-electricity during the peak power consumption. This measure not only alleviates the situation of tight power consumption during peak power consumption, but also charges the remaining generated electricity during low-valley power consumption at the standard of peak power consumption, improving the power supply during peak power consumption, and thus improving the economic benefits.
