Description

Technical Field

[0001] The present invention relates to the field of energy conversion technology, and in particular to an electric energy conversion system based on solar radiation energy and natural fluid thermal energy. Background Art

[0002] As a clean, renewable energy source, solar energy has great potential to meet the world's growing demand for electricity. With the decreasing dependence on traditional fossil fuels and the increasing awareness of environmental protection, research and development of efficient solar energy conversion technologies are crucial to achieving sustainable development.

[0003] In existing technologies, photovoltaic panels are commonly used to convert solar energy into electricity. However, this approach has certain limitations. Specifically, photovoltaic panels are typically composed of several silicon wafers, and the manufacturing process for silicon wafers is complex and requires high precision, resulting in high production costs. Furthermore, photovoltaic panels require a large floor space when used.

[0004] To sum up, how to solve the problems of high cost and large area occupied by photovoltaic panels for electricity conversion in the existing technology has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose an electricity conversion system based on solar radiation energy and natural fluid thermal energy. Summary of the Invention

[0005] To address these issues, the present invention provides an electric energy conversion system based on solar radiation and natural fluid thermal energy. By integrating multiple components, this system achieves the same energy output in a smaller space, reducing installation costs and space requirements. Buoyancy is leveraged to propel the semi-enclosed enclosure up and down, providing kinetic energy to the moving components, which in turn drives the generator and gas compressor. This enables efficient multi-stage energy transfer and utilization, thereby reducing costs.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: an electric energy conversion system based on solar radiation energy and natural fluid thermal energy, comprising a heat transfer working medium A and a heat transfer working medium B and the following modules and components:

[0007] The thermal energy collection module is used to receive thermal energy generated by sunlight and transfer the thermal energy to the thermal energy storage module.

[0008] The thermal energy storage module is used to store the thermal energy conducted from the thermal energy collection module, use the thermal energy to heat the heat transfer working medium A; and transmit the heated heat transfer working medium A to the bubble buoyancy turbine module.

[0009] The bubble buoyancy turbine module is used to receive the heat transfer working medium A after heating treatment, and convert the vaporization and liquefaction process of the heat transfer working medium A into kinetic energy to drive the generator and gas compressor to work.

[0010] The heat exchange tube is used to connect the thermal energy storage module and the bubble buoyancy turbine module to transfer heat.

[0011] The generator is used to drive the generator to rotate by utilizing the bubble buoyancy turbine module, and convert the mechanical energy generated by the rotation of the generator into electrical energy.

[0012] The gas compressor is used to utilize the bubble buoyancy turbine module to drive the gas compressor to start and compress the heat transfer working medium B.

[0013] The internal evaporator is located inside the bubble buoyancy turbine module and is used to absorb gas heat and liquefy the heat transfer working medium A.

[0014] The external evaporator is located outside the bubble buoyancy turbine module and is used to absorb fluid heat from the natural environment.

[0015] The condenser is located inside the thermal energy storage module and is used to cool the heat transfer working medium B after being heated by the gas compressor and release heat.

[0016] The expansion valve is connected to the inner evaporator, outer evaporator and condenser respectively, and is used to adjust the state of the heat transfer working medium B.

[0017] Intelligent control module, used to monitor and control the operation of various modules and components in the system.

[0018] Furthermore, the thermal energy storage module is composed of a sealed first container and an aqueous solution in the first container.

[0019] Furthermore, the bubble buoyancy turbine module consists of a sealed second container, several semi-enclosed boxes, several rotating shafts and several chains; the heat transfer working medium A is stored in the sealed second container, and the chain is used to connect the semi-enclosed boxes and the rotating shafts.

[0020] Furthermore, the working steps of the thermal energy storage module are as follows:

[0021] S101, transferring the heat energy collected by the heat energy collection module to the heat energy storage module to heat the aqueous solution in the first container.

[0022] S102. When the temperature of the aqueous solution rises, the heat exchange tube transfers heat to the heat transfer working medium A in the bubble buoyancy turbine module.

[0023] S103. When the surface temperature T1 of the heat exchange tube exceeds the boiling point T2 of the heat transfer working medium A, the heat transfer working medium A on the surface of the heat exchange tube vaporizes and converts into gas.

[0024] S104: Transmit the converted gas to the bubble buoyancy turbine module.

[0025] Furthermore, in S103, the boiling point T2 of the heat transfer working medium A is 40-80°C.

[0026] Furthermore, the working steps of the bubble buoyancy turbine module are as follows:

[0027] S201. The converted gas is introduced into a plurality of semi-enclosed boxes immersed in a heat transfer working medium A and filled with the semi-enclosed boxes. After being filled with gas, the semi-enclosed boxes move upward under the action of buoyancy. When they move to the highest point, the gas and heat transfer working medium A inside the semi-enclosed boxes are discharged.

[0028] S202. After the gas is discharged, the semi-enclosed boxes move downward under the action of gravity and sink into the heat transfer working medium A. During the sinking process, the semi-enclosed boxes are filled with the heat transfer working medium A again and then descend to the lowest point.

[0029] S203. When the semi-enclosed box descends to the lowest point, it is filled with the converted gas again and continues to float up. During the process of the semi-enclosed box continuously floating up and down, the rotating shaft is driven to rotate by the chain; the rotation of the rotating shaft drives the generator and the gas compressor to work.

[0030] Further, the working steps of the gas compressor are as follows:

[0031] S301. Add heat transfer working medium B to the gas compressor. The gas compressor compresses and heats the heat transfer working medium B to a temperature T3, which is higher than the boiling point T2.

[0032] S302: The heated heat transfer working medium B flows through the condenser, and the condenser releases the heat and transfers it to the aqueous solution in the thermal energy storage module, and the temperature drops to T4.

[0033] S303, the cooled heat transfer working medium B is transferred to the expansion valve, and the expansion valve converts the heat transfer working medium B into a low-temperature and low-pressure gas-liquid mixture, the temperature of which is reduced to T5, and the T5 temperature is lower than 0°C.

[0034] S304. The heat transfer working medium B with a lowered temperature flows into the inner evaporator and the outer evaporator respectively; the heat transfer working medium B in the inner evaporator and the outer evaporator absorbs heat from the environment and vaporizes. After the vaporization reaction, the temperature rises to T6 and flows back to the gas compressor.

[0035] S305. At the same time, the internal evaporator reduces the temperature of the heat transfer working medium A gas and liquefies it and flows back into the bubble buoyancy turbine module, and the cycle is repeated continuously under the drive of the rotating shaft.

[0036] Furthermore, the cooling power of the inner evaporator is greater than the heating power of the heat exchange tube in the bubble buoyancy turbine module.

[0037] Furthermore, the intelligent control module includes the following units:

[0038] Sensing units are used to monitor the temperature, pressure and flow of each module and component in the system.

[0039] The control unit is used to adjust the fluid flow, the pressure of the gas compressor and the opening of the expansion valve according to the data fed back by the sensing unit.

[0040] The protection unit is used to set the monitoring threshold of the sensor unit, cut off the power supply and send out an alarm signal under abnormal circumstances.

[0041] A remote control unit is used to provide a remote control interface.

[0042] Furthermore, the intelligent control module also includes an energy management unit, which is used to adjust the angle of the thermal energy collection module, track and concentrate sunlight; and store the electrical energy generated by the generator.

[0043] The above scheme has the following beneficial effects:

[0044] 1. The present invention effectively receives thermal energy generated by sunlight through a thermal energy collection module and stores it in a thermal energy storage module to heat a water solution. A heat exchange tube acts as a heat transfer medium, vaporizing the water solution under appropriate temperature conditions. The vaporized gas is efficiently transferred to the bubble buoyancy turbine module. The gas moves up and down through the semi-enclosed box, forming a continuous energy conversion process. This process not only converts thermal energy into mechanical energy, but also drives the rotating shaft through a chain, further driving the generator and gas compressor, achieving efficient multi-stage energy transfer and utilization, thereby reducing costs.

[0045] Using solar energy as the main energy source reduces dependence on fossil fuels and helps reduce greenhouse gas emissions and other pollutants.

[0046] 2. Through multi-stage heat exchange between the heat exchange tubes, condenser, internal evaporator, and external evaporator, the present invention enables the system to more efficiently utilize heat from various sources, thereby improving overall thermal efficiency. This system not only utilizes solar radiation heat energy, but also incorporates the heat energy of low-temperature fluids in nature, further improving overall energy utilization. The entire system forms a self-sustaining energy conversion cycle, reducing the need for external energy, improving energy conversion efficiency, and further reducing costs.

[0047] The internal evaporator not only helps reduce the temperature of the heat transfer working medium A gas and liquefies it to flow back into the bubble buoyancy turbine module, but also effectively manages the heat distribution within the system by having its cooling power greater than the heating power of the heat exchange tube in the bubble buoyancy turbine module. The expansion valve precisely adjusts the state of the heat transfer working medium B to ensure that the internal pressure and temperature of the system remain within a safe range, reducing the system failure rate caused by overpressure or low temperature.

[0048] 3. The bubble buoyancy turbine module of the present invention uses buoyancy to move the semi-enclosed box up and down, thereby providing kinetic energy for the moving parts and converting the kinetic energy into electrical energy, which in turn can power the electrical components of the device. This natural physical phenomenon reduces the demand for additional power and ensures the stability and reliability of the system.

[0049] 4. By introducing an intelligent control module, this invention enables the system to adapt itself to various environments, ensuring long-term stable operation. The presence of a protection unit effectively prevents malfunctions or damage caused by external conditions. The collaborative operation of the sensing unit and control unit enables refined management and real-time regulation of all parts of the system, effectively reducing energy loss and improving overall energy conversion efficiency.

[0050] The remote control unit offers flexible operation, allowing users to monitor and manage the system's operating status anytime, anywhere, facilitating routine maintenance and troubleshooting. The addition of the energy management unit not only improves the system's energy absorption capacity but also makes it suitable for a wider range of environments. By integrating multiple components, the system can achieve the same energy output in a smaller space, reducing installation costs and space requirements.

[0051] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The following is further described in detail through specific implementation methods:

[0057] Example 1:

[0058] As attached Figure 1 As shown: An electric energy conversion system based on solar radiation energy and natural fluid thermal energy is mainly composed of a thermal energy collection module, a thermal energy storage module, a bubble buoyancy turbine module, a heat exchange tube 4, a generator 5, a gas compressor 6, an inner evaporator 7, an outer evaporator 7, a condenser 9, an expansion valve 10 and an intelligent control module.

[0059] Among them, the heat energy collection module is mainly used to receive heat energy generated by sunlight; the heat energy storage module is used to store heat energy conducted from the heat energy collection module; the bubble buoyancy turbine module is used to drive the generator 5 and the gas compressor 6 to work; the heat exchange tube 4 is used to transfer heat; the generator 5 is used to convert mechanical energy into electrical energy. In this embodiment, the generator 5 uses a permanent magnet generator; the gas compressor 6 is used to compress the heat transfer working medium B; the internal evaporator 7 is used to absorb gas heat and liquefy the heat transfer working medium A. In this embodiment, the heat transfer working medium A is dichloromethane 13; the external evaporator 7 is used to absorb fluid heat in the natural environment; the condenser 9 is used to cool the heat transfer working medium B heated by the gas compressor 6. In this embodiment, the heat transfer working medium B is n-hexane 14; and release heat; the expansion valve 10 is used to adjust the state of the heat transfer working medium B; the intelligent control module is used to monitor and control the operation pipeline 11 of each module and component in the system.

[0060] The specific functions of each module and component are as follows:

[0061] The thermal energy collection module is used to receive the thermal energy generated by sunlight and transfer the thermal energy to the thermal energy storage module; in this embodiment, the thermal energy collection module adopts high-efficiency heat collection materials and technologies, such as focusing mirror reflection, multi-layer insulation structure, etc., to enhance the absorption efficiency of sunlight and reduce heat loss.

[0062] The thermal energy storage module consists of a sealed first container and an aqueous solution in the first container. In this embodiment, the aqueous solution is a propylene glycol aqueous solution 12, which is mainly used to store the heat energy conducted from the thermal energy collection module and use the heat energy to heat the heat transfer working medium A; and transmit the heated heat transfer working medium A to the bubble buoyancy turbine module.

[0063] Specifically, the working steps of the thermal energy storage module are as follows:

[0064] S101, transferring the heat energy collected by the heat energy collection module to the heat energy storage module to heat the aqueous solution in the first container.

[0065] S102: When the temperature of the aqueous solution rises, the heat exchange tube 4 transfers heat to the heat transfer working medium A in the bubble buoyancy turbine module.

[0066] S103. When the surface temperature T1 of the heat exchange tube 4 exceeds the boiling point T2 of the heat transfer working medium A, the heat transfer working medium A on the surface of the heat exchange tube 4 vaporizes and converts into gas. In this embodiment, the boiling point T2 is 75°C.

[0067] S104: Transmit the converted gas to the bubble buoyancy turbine module.

[0068] The bubble buoyancy turbine module consists of a sealed second container, several semi-enclosed boxes, several rotating shafts, and several chains. Heat transfer working medium A is stored in the sealed second container, and the chains connect the semi-enclosed boxes to the rotating shafts. The bubble buoyancy turbine module receives the heated heat transfer working medium A and converts the vaporization and liquefaction of the heat transfer working medium A into kinetic energy, driving the generator 5 and gas compressor 6.

[0069] The heat exchange tube 4 is used to connect the thermal energy storage module and the bubble buoyancy turbine module to transfer heat; it ensures that heat can be accurately transferred from the thermal energy storage module to the heat transfer working medium A in the bubble buoyancy turbine module, providing the necessary heat source support for subsequent energy conversion.

[0070] Specifically, the working steps of the bubble buoyancy turbine module are as follows:

[0071] S201. The converted gas is introduced into a plurality of semi-enclosed boxes immersed in a heat transfer working medium A and filled with the semi-enclosed boxes. After being filled with gas, the semi-enclosed boxes move upward under the action of buoyancy. When they move to the highest point, the gas and heat transfer working medium A inside the semi-enclosed boxes are discharged.

[0072] S202. After the gas is discharged, the semi-enclosed boxes move downward under the action of gravity and sink into the heat transfer working medium A. During the sinking process, the semi-enclosed boxes are filled with the heat transfer working medium A again and then descend to the lowest point.

[0073] S203. When the semi-enclosed box descends to the lowest point, it is filled with the converted gas again and continues to float up. During the process of continuous floating up and down, the rotating shaft is driven by the chain to rotate; the rotating shaft rotates to drive the generator 5 and the gas compressor 6 to work.

[0074] The generator 5 is used to drive the generator 5 to rotate using the bubble buoyancy turbine module, and convert the mechanical energy of the generator 5 into electrical energy; in this example, the generator 5 adopts conventional technical means, and its principle is not described in detail in this embodiment.

[0075] The gas compressor 6 is used to start the gas compressor 6 by using the bubble buoyancy turbine module to compress the heat transfer working medium B.

[0076] The internal evaporator 7 is located inside the bubble buoyancy turbine module and is used to absorb gas heat and liquefy the heat transfer working medium A. The cooling power of the internal evaporator 7 is greater than the heating power of the heat exchange tube 4 in the bubble buoyancy turbine module, effectively managing the heat distribution in the system.

[0077] The external evaporator 7 is located outside the bubble buoyancy turbine module and is used to absorb fluid heat in the natural environment to enhance the energy utilization efficiency of the system.

[0078] The condenser 9 is located inside the thermal energy storage module and is used to cool the heat transfer working medium B heated by the gas compressor 6 and release heat.

[0079] The expansion valve 10 is connected to the inner evaporator 7, the outer evaporator 7 and the condenser 9 respectively, and is used to adjust the state of the heat transfer working medium B to ensure that it is under appropriate low temperature and low pressure conditions when entering the inner evaporator 7 and the outer evaporator 7.

[0080] The intelligent control module is used to monitor and control the operation of each module and component in the system.

[0081] Specifically, the working steps of the gas compressor 6 are as follows:

[0082] S301 . Add heat transfer working medium B to the gas compressor 6 . The gas compressor 6 compresses and heats the heat transfer working medium B to raise its temperature to T3 . The temperature T3 is higher than the boiling point T2 .

[0083] S302: The heated heat transfer working medium B flows through the condenser 9, and the condenser 9 releases the heat and conducts it into the aqueous solution of the thermal energy storage module, and the temperature is reduced to T4.

[0084] S303, the cooled heat transfer working medium B is transferred to the expansion valve 10, and the expansion valve 10 converts the heat transfer working medium B into a low-temperature and low-pressure gas-liquid mixture, the temperature of which is reduced to T5, and the T5 temperature is lower than 0°C.

[0085] S304. The heat transfer working medium B after the temperature is reduced flows into the inner evaporator 7 and the outer evaporator 7 respectively; the heat transfer working medium B in the inner evaporator 7 and the outer evaporator 7 absorbs heat from the environment and vaporizes. After the vaporization reaction, the temperature rises to T6 and flows back to the gas compressor 6.

[0086] S305. At the same time, the internal evaporator 7 reduces the temperature of the heat transfer working medium A and liquefies it and flows back into the bubble buoyancy turbine module, and the cycle is repeated continuously under the drive of the rotating shaft.

[0087] In the prior art, when converting solar energy into electrical energy, photovoltaic panels are usually used. They are mainly made of silicon wafers, and the production cost of silicon wafers is relatively high. When solar panels are used, they also occupy a large area. In this embodiment, the heat energy generated by sunlight is effectively received by the thermal energy collection module and stored in the thermal energy storage module to heat the aqueous solution. The heat exchange tube 4 serves as a medium for heat transfer. Under appropriate temperature conditions, the aqueous solution is vaporized and the vaporized gas is efficiently transferred to the bubble buoyancy turbine module. The gas forms a continuous energy conversion process through the up and down reciprocating motion of the semi-enclosed box. This process not only converts thermal energy into mechanical energy, but also drives the rotating shaft to rotate through the chain, further driving the generator 5 and the gas compressor 6 to work, thereby realizing the effective transmission and utilization of multi-stage energy.

[0088] This embodiment utilizes multi-stage heat exchange between the heat exchange tubes 4, condenser 9, internal evaporator 7, and external evaporator 7, enabling the system to more efficiently utilize heat from various sources, thereby improving overall thermal efficiency. The internal evaporator 7 not only helps reduce the temperature of the heat transfer working medium A gas and liquefies it for reflow into the bubble buoyancy turbine module, but also effectively manages heat distribution within the system by ensuring its cooling power is greater than the heating power of the heat exchange tubes 4 within the bubble buoyancy turbine module. The expansion valve 10 precisely regulates the state of the heat transfer working medium B, ensuring that the system's internal pressure and temperature remain within a safe range, thereby reducing the risk of system failures due to overpressure or low temperatures.

[0089] The system not only utilizes solar radiation but also incorporates the thermal energy of low-temperature fluids in nature, further improving overall energy efficiency. The entire system forms a self-sustaining energy conversion cycle, reducing the need for external energy, improving energy conversion efficiency, and further lowering costs. The integration of multiple components allows for the same energy output in a smaller space, reducing installation costs and space requirements.

[0090] Example 2:

[0091] As attached Figure 2 As shown, the difference from the above embodiment is that the intelligent control module includes the following units:

[0092] The sensing unit is used to monitor the temperature, pressure and flow of each module and component in the system. In this embodiment, the sensing unit mainly includes a pressure sensor, a temperature sensor and a flow sensor.

[0093] The control unit is used to adjust the fluid flow, the pressure of the gas compressor 6 and the opening of the expansion valve 10 according to the data fed back by the sensor unit. In this embodiment, the control unit mainly includes a controller and an actuator.

[0094] The protection unit is used to set the monitoring threshold of the sensor unit, cut off the power supply and send out an alarm signal under abnormal circumstances. In this embodiment, the alarm signal is sent out using a buzzer.

[0095] The remote control unit is used to provide a remote control interface; it allows users to view system performance in real time through the Internet or mobile applications and make necessary operational settings, such as starting / stopping certain components or adjusting operating parameters.

[0096] The energy management unit is used to adjust the angle of the thermal energy collection module to track and concentrate sunlight; and to store the electrical energy generated by the generator 5. In this embodiment, batteries or supercapacitors can be used to store the converted electrical energy.

[0097] This embodiment, through the introduction of an intelligent control module, enables the system to adapt to various environments, ensuring long-term stable operation. The presence of a protection unit effectively prevents malfunctions or damage caused by external conditions. The collaborative operation of the sensing unit and control unit enables refined management and real-time regulation of all system components, effectively reducing energy losses and improving overall energy conversion efficiency.

[0098] The remote control unit provides flexible operation, allowing users to monitor and manage the system's operating status anytime, anywhere, facilitating routine maintenance and troubleshooting. The addition of the energy management unit not only improves the system's energy absorption capacity, but also makes it suitable for a wider range of environments.

[0099] Example 3:

[0100] As attached Figure 3 As shown, the difference from the above embodiment is that an electric energy conversion system based on solar radiation energy and natural fluid thermal energy consists of the following parts: a solar radiation thermal energy collection device 1, a thermal energy storage device 2, a bubble buoyancy turbine device 3 for converting thermal energy into kinetic energy, a heat exchange tube 4 connecting the thermal energy storage device 2 and the bubble buoyancy turbine device 3, a generator 5 driven by the bubble buoyancy turbine device, a gas compressor 6 driven by the bubble buoyancy turbine device, an inner evaporator 7 for absorbing gas heat placed in the bubble buoyancy turbine device 5, an outer evaporator 8 for absorbing natural environment fluid heat placed outside the bubble buoyancy turbine device 5, a condenser 9 for releasing heat placed in the thermal energy storage device 2, an expansion valve 10 connected to the evaporator 7, 8 and condenser 9 respectively, a pipeline 11 connecting the inner evaporator 7, the outer evaporator 8, the condenser 9 and the gas compressor 6, and an intelligent control module.

[0101] The system converts solar radiation energy and natural fluid thermal energy into electrical energy in the following way:

[0102] ① After the solar radiation heat energy collection device 1 receives the heat energy generated by sunlight, it continuously conducts the heat energy to the glycerol aqueous solution 12 in the thermal energy storage device 2 through the pipe 11 and the heat-conducting liquid in the pipe 11, causing the water temperature to gradually rise.

[0103] ② When the water temperature of the thermal energy storage device 2 rises, the heat exchange tube 4 connecting the thermal energy storage device 2 and the bubble buoyancy turbine device 3 transfers heat to the dichloromethane 13 in the bubble buoyancy turbine device 3. When the surface temperature T1 of the heat exchange tube 4 exceeds the boiling point T2 of the dichloromethane 13, the dichloromethane 13 on the surface of the heat exchange tube 4 vaporizes and converts into gas.

[0104] ③ The generated gas is introduced into nine semi-enclosed rectangular containers immersed in and filled with liquid dichloromethane 13. The nine gas-filled containers move upward due to buoyancy and, at their highest possible point, sequentially discharge the gas and dichloromethane 13 from their interiors. Subsequently, several empty containers move downward under gravity and sink into the liquid dichloromethane 13, becoming filled with dichloromethane 13 again as they sink until they reach their lowest possible point. This process repeats itself.

[0105] ④ The container that reciprocates up and down in the bubble buoyancy turbine device 3 drives two rotating shafts to rotate through a transmission chain, one of which drives the generator 5 to generate electricity, and the other drives the gas compressor 6 to work.

[0106] ⑤ Gaseous n-hexane 14 flowing into gas compressor 6 through pipeline 11 is compressed and heated by gas compressor 6 to a temperature T3, which is higher than the boiling point T2 of 13. After flowing through heat-releasing condenser 9 within thermal energy storage device 2, the n-hexane 14 transfers heat to the glycerol aqueous solution 12 within thermal energy storage device 2, lowering its temperature to T4. Subsequently, the n-hexane 14 flows through expansion valve 10, becoming a low-temperature, low-pressure gas-liquid mixture, whose temperature drops to T5, which is below 0°C. The low-temperature n-hexane 14 flows into internal evaporator 7 within bubble buoyancy turbine device 3 and external evaporator 8 outside bubble buoyancy turbine device 3, respectively. The n-hexane 14 absorbs heat from the surrounding environment, vaporizing and raising its temperature to T6 before returning to gas compressor 6. Simultaneously, internal evaporator 7 reduces the methylene chloride 13 gas generated in step ③, liquefying it and flowing it back into bubble buoyancy turbine device 3. This process repeats continuously, driven by the rotating shaft.

[0107] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
