[0002] In remote areas of my country and in single-family homes abroad, relatively weak energy infrastructure makes it challenging to provide stable and reliable energy security for residential users. To ensure sufficient energy and reduce energy costs, users often use a hybrid energy system consisting of multiple energy sources, including solar energy, wind energy, natural gas / biogas, and grid electricity, to provide comprehensive energy support for electrical appliances, heating systems, and domestic hot water supply systems.

[0003] However, existing hybrid energy systems lack a unified and coordinated energy management strategy during their construction and operation. In particular, a systematic, logical comparison and optimization mechanism for selecting and optimizing the various energy sources, including solar, wind, and natural gas / biogas, for generation and storage, based on their characteristics, supply timeliness, and residential load demands, has yet to be established. This lack of coordinated control can result in some energy resources being underutilized, limiting the overall efficiency and stability of the energy system. Summary of the Invention

[0034] In a second aspect, the present application provides a scheduling method for a clean energy storage regulation system, which adopts the following technical solutions:

[0035] A scheduling method for a clean energy storage and regulation system, applied to a clean energy storage and regulation system described in the above technical solution, comprises the following steps:

[0036] During the day, the photovoltaic panels are in the first state, the cogeneration unit is turned off, the photovoltaic panels are used to generate electricity and the output electricity is stored in the energy storage device, and the photovoltaic panels are cooled by the cooling module and the cogeneration unit;

[0037] At night, the photovoltaic panels are in the second state, the cogeneration unit is turned on, and the nozzle sprays coolant on the front to clean the surface for a set time;

[0038] After completing the front cleaning, adjust the spray pressure of the nozzle to the preset range so that the coolant does not contact the front to keep the photovoltaic panel warm.

[0039] The present invention has the following advantages and beneficial effects:

[0040] The clean energy storage and regulation system provided in this application integrates multiple energy forms such as solar power generation, cogeneration power generation and energy storage control, and introduces a posture-switchable structure of photovoltaic panels, so that the system has the ability to dynamically adjust the operating mode according to environmental conditions, and can achieve optimal scheduling of energy supply under different time periods and working conditions, which helps to meet the application needs of multi-source coordination, stable output and energy saving and consumption reduction.

[0041] During daytime operation, the cogeneration unit is not generating electricity, meaning it is not burning fuel or outputting electricity. At this time, the photovoltaic panel is generating electricity, with its back facing the cooling module. The coolant in the cooling module can flow through the cogeneration unit, exchanging heat with the structural components of the cogeneration unit, thereby creating a heat dissipation path. When the cogeneration unit is not operating, it can serve as a heat dissipation channel for the coolant, helping to lower the temperature of the coolant. This allows the coolant flowing back to the cooling module to effectively cool the photovoltaic panel. Therefore, the photovoltaic panel can operate within a relatively suitable temperature range, which helps improve the panel's power generation efficiency and operational stability, and enhances the system's energy scheduling capabilities.

[0042] During nighttime operation, the photovoltaic panels switch to a non-power-generating state, with their fronts facing the cooling module, while the cogeneration unit is in power-generating operation. The heat generated during power generation is transferred to the cooling module via the coolant, which, to a certain extent, can give the cooling module a heating function, thereby regulating the temperature of the front of the photovoltaic panels. This structure can alleviate material thermal fatigue and icing caused by low temperatures or sudden temperature changes, thereby helping to extend the service life of the photovoltaic panel components and enhance their environmental adaptability. In addition, the nozzles installed in the cooling module can flush the front of the photovoltaic panel when it is not in operation, which helps to remove dust and particle deposits, provide favorable guarantees for maintaining good light conditions for the next working cycle, and indirectly improve power generation efficiency.

[0043] Through the above-mentioned structural coordination and control strategy, this system not only improves the ability to integrate and utilize multiple sources of energy, but also enhances the system's operational stability and reliability under complex climatic conditions. This can, to a certain extent, alleviate the problems existing in existing technologies, such as delayed energy regulation response, equipment maintenance relying on manual operation, and photovoltaic panels being easily affected by the environment, leading to performance degradation.

DETAILED DESCRIPTION

[0053] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0054] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0055] First, refer to Figures 1 to 6 As shown, the present application provides a clean energy storage and regulation system, including a support module 100, a cogeneration unit 300, a photovoltaic panel 200, an energy storage device 400, and a cooling module 500. The system is suitable for integrating multiple energy forms, achieving coordinated energy output and dynamic regulation, and adapting to the energy supply and demand requirements of various operating conditions.

[0056] The support module 100 provides mechanical support and a relatively fixed connection foundation for the installation of various functional components. The specific structural form of the support module 100 can be a frame structure, a guide rail structure, or an adjustable angle mounting platform. The specific structure selected can be configured according to the installation environment, providing a certain degree of structural adaptability.

[0057] Photovoltaic panels 200 are mounted on support module 100 and are used to generate solar power during daytime hours when sunlight is abundant. These panels can be conventional crystalline silicon or thin-film photovoltaic modules. Their mounting orientation and inclination can be optimized based on the location and seasonal sunlight angle, thereby improving sunlight reception efficiency and power generation capacity.

[0058] The cogeneration unit 300 generates electricity using gas or other combustible fuels. It includes an engine and a generator. The engine burns fuel to generate mechanical energy, which drives the generator to generate electrical energy. In this system, the cogeneration unit 300 not only serves as a supplemental or nighttime energy source but also collaborates with the cooling module 500 to form an integrated temperature control structure, achieving bidirectional heating and cooling. It should be noted that since the cogeneration unit 300 generates a large amount of heat during operation, the cooling module 500 is essential.

[0059] The cooling module 500 can be a circulating coolant structure with internal cooling channels. As the coolant flows through the pipes, it carries heat and performs heat exchange operations. Specifically, during operation, the coolant forms a heat conduction path between the cogeneration unit 300 and the photovoltaic panel 200, enabling switching between cooling and heating functions under different operating conditions. The connection structure between the cooling module 500 and the cogeneration unit 300 can be a heat-conducting metal heat exchange plate, a heat exchanger, or a pipe heat exchange unit, which helps enhance the heat transfer efficiency of the coolant within the system.

[0060] During daytime operation, the photovoltaic panel 200 is generating electricity, with its back surface 220 in contact with the cooling module 500. Coolant in the cooling module 500 flows through the heat exchange components within the cogeneration unit 300. Since the cogeneration unit 300 does not generate electricity during the day (i.e., it does not burn fuel), it does not generate heat itself and can serve as a heat dissipation channel for the coolant. In this way, the coolant absorbs heat from the back surface 220 of the photovoltaic panel 200, undergoes heat exchange through the cogeneration unit 300, and its temperature is lowered before flowing back to the cooling module 500. This cools the photovoltaic panel 200, allowing it to operate within a relatively suitable temperature range, which is beneficial for improving its photoelectric conversion efficiency and operational stability.

[0061] During nighttime operation, the photovoltaic panel 200 enters a non-generating state, with its front face 210 facing the cooling module 500. Simultaneously, the cogeneration unit 300 is generating electricity. Heat generated during power generation is absorbed by the coolant and transferred to the cooling module 500. After absorbing heat, the cooling module 500 can, to a certain extent, perform a heating function, thereby regulating the temperature of the front face 210 of the photovoltaic panel 200. This structure effectively mitigates issues such as component thermal fatigue and surface frost caused by low temperatures or drastic temperature swings between day and night, helping to extend the service life of the photovoltaic panel 200 components and improve their operational adaptability in various climates.

[0062] It can be seen from the above-mentioned implementation structure that the clean energy storage and regulation system provided by this application realizes the structural integration of photovoltaic components and cogeneration modules in the overall configuration, and constructs a cooling-heating bidirectional heat exchange path through the cooling module 500. It can collaboratively complete the efficient management and output regulation of energy under different working conditions, and has good practical value and promotion prospects.

[0063] In some embodiments, reference Figure 1 、 Figure 2 The cooling module 500 is used to cool the photovoltaic panels 200 and the cogeneration unit 300. The cooling module 500 not only cools the photovoltaic panels 200 but also regulates the temperature of the cogeneration unit 300, creating a combined cooling path for cooling multiple components within the system. Specifically, the cooling module 500 includes a coolant circulation loop equipped with a circulating pump, heat conduction channels, and heat exchange components. The coolant circulates within the closed loop within the system and performs heat exchange operations with the photovoltaic panels 200 and the cogeneration unit 300, respectively.

[0064] The cooling module 500 can be arranged in a series configuration. This means that after flowing through the photovoltaic panels 200, the coolant continues to flow to the combined heat and power unit 300, thereby regulating the temperatures of both heat source units through a single loop. This series configuration offers the advantages of compactness and high system integration, simplifying the cooling system's piping design while reducing the number of components and installation complexity.

[0065] During the day, the coolant first exchanges heat with the contact area of ​​the back surface 220 of the photovoltaic panel 200, absorbing surface heat generated by solar radiation. This cools the photovoltaic panel 200 to a certain extent, allowing it to operate within a relatively suitable temperature range, thereby helping to improve its photoelectric conversion efficiency. The coolant then carries the absorbed heat into the cooling unit 232 of the cogeneration unit 300, exchanging heat with high-heat source structures within the cogeneration unit 300, such as the cylinder, shell, or heat exchanger, thereby transferring the heat in the coolant to the cogeneration unit 300. This improves the cooling effect on the photovoltaic panel 200 during the day.

[0066] It should be noted that during the day, when necessary, the cogeneration unit 300 can also be turned on to generate electricity. At this time, although the coolant continuously exchanges heat with the two target components in the series path, the heat generated by the photovoltaic panel 200 is relatively lower than the heat generated when the cogeneration unit 300 is in operation, and the cooling module 500 can have a certain cooling effect. Therefore, the series system still has an acceptable cooling capacity distribution efficiency under most operating conditions.

[0067] Furthermore, under certain special operating conditions, such as when insufficient sunlight causes the photovoltaic panels 200's power generation capacity to decline, the system can switch to a mode where the photovoltaic panels and the combined heat and power generation unit 300 operate in parallel. In this mode, the combined heat and power generation unit 300 can be activated to supplement the power output, thereby maintaining the continuity and stability of the system's external energy supply.

[0068] In this operating state, due to insufficient external sunlight, the heat absorption on the surface of the photovoltaic panel 200 is limited, resulting in a relatively low heat output. Simultaneously, to accommodate system load requirements, the cogeneration unit 300 can operate in a low-power state, i.e., a relatively low heat load condition. In this scenario, although the cooling module 500 still needs to cool both the photovoltaic panel 200 and the cogeneration unit 300, the combined heat load of both in this mode is relatively small. Therefore, the heat exchange burden borne by the cooling module 500 remains within a reasonable range, and the cooling capacity allocation efficiency of the series system remains highly adaptable and acceptable.

[0069] Furthermore, this operational logic demonstrates the system's dynamic adaptability in the context of multi-energy coordinated dispatch. By adjusting the operating status of power generation units and the allocation strategy of cooling paths based on varying environmental parameters, it is possible to achieve a certain degree of synergy between energy efficiency and system thermal management capabilities, thereby providing structural support and operational assurance for stable, all-weather energy supply.

[0070] The cooling path of this series system can be dynamically adjusted using control components such as three-way valves, temperature control valves, or circuit breaker components. For example, during daytime operation, the coolant can be controlled to flow preferentially through photovoltaic panels 200 before entering the non-operating cogeneration unit 300, thus serving as a heat dissipation channel for the coolant. During nighttime operation, the path can be switched so that the coolant primarily exchanges heat with the operating cogeneration unit 300, ensuring the unit's thermal management requirements. This orderly regulation of the coolant path facilitates thermal balance management and energy efficiency optimization for the entire system.

[0071] In summary, the series structural design of the cooling module 500 between the photovoltaic panel 200 and the cogeneration unit 300 not only improves the system's integration and layout rationality, but also provides stable temperature control support for energy conversion components under multiple working conditions, helping to extend equipment life and improve system operating efficiency.

[0072] Figure 1 In the figure, the dotted line indicates the flow direction of the coolant, and the solid line indicates the flow direction of the current.

[0073] In some embodiments, the energy storage device 400 is used to receive and store the electrical energy generated by the photovoltaic panel 200 and the cogeneration unit 300 to achieve regulation and timed release of electrical energy, thereby providing stable electrical energy support for electrical equipment or system loads during different operating periods.

[0074] Specifically, the energy storage device 400 can be in the form of a battery, such as a lithium-ion battery, a lead-acid battery, a sodium-sulfur battery or other electrochemical energy storage device 400 suitable for large-scale energy storage, which is used to realize energy charging and discharging conversion in an electrochemical manner, thereby having characteristics such as fast response speed and high control accuracy.

[0075] In other embodiments, energy storage device 400 may include a pumped-storage structure, which uses electricity to drive a water pump to transfer water from a lower reservoir to a higher reservoir. When system load demand increases or sunlight is insufficient, water is released from the higher reservoir to the lower reservoir, driving a turbine to generate electricity, thereby converting previously stored potential energy back into electrical energy. This type of energy storage offers advantages such as large storage capacity and long service life in scenarios with large head heights and water storage conditions. It is suitable for coordinated operation with renewable energy power generation systems, enhancing the system's overall load balancing and regulation capabilities.

[0076] By setting up the above-mentioned multi-type energy storage structures, it is beneficial to improve the system's energy utilization flexibility and operational stability, and enhance its ability to cope with external disturbances such as load fluctuations and light changes.

[0077] It is understandable that the energy storage device 400 may also be other energy storage forms such as supercapacitors, flywheel energy storage, hydrogen energy, etc. This embodiment does not limit the specific form of the energy storage device 400.

[0078] In some embodiments, reference Figure 2 、 Figure 4 The cooling module 500 includes a nozzle 510. The photovoltaic panel 200 is movably mounted on the support module 100 to switch between a first state and a second state. The photovoltaic panel 200 has a front surface 210 and a back surface 220. The front surface 210 is the primary light-entering surface, and the back surface 220 is used to provide a heat dissipation structure. When the photovoltaic panel 200 is in the first state, the back surface 220 is in contact with the cooling module 500. When the photovoltaic panel 200 is in the second state, the photovoltaic panel 200 is spaced apart from the cooling module 500, with the front surface 210 facing the cooling module 500. The nozzle 510 is used to spray coolant onto the front surface 210.

[0079] When the photovoltaic panel 200 is in the first state, its back side 220 faces the cooling module 500 and is arranged in contact with the cooling module 500, so as to facilitate heat conduction and heat dissipation control of the photovoltaic panel 200 through the cooling module 500, so that the photovoltaic panel 200 can maintain a more suitable temperature range during the power generation process, which is beneficial to improving power generation efficiency and operational stability.

[0080] When the photovoltaic panel 200 is in the second state, the photovoltaic panel 200 is flipped so that its front side 210 faces the cooling module 500 and is spaced apart from the cooling module 500. The nozzles 510 in the cooling module 500 can spray coolant onto the front side 210 of the photovoltaic panel 200. This state is often used for protecting and cleaning the photovoltaic panel 200 during non-power generation periods (e.g., at night).

[0081] Specifically, the spray head 510 can be connected to a liquid supply assembly consisting of a liquid storage tank, pipes, and solenoid valves. Under the control of a control unit, the cleaning function is activated when set conditions (such as cycle time, light intensity, ambient temperature, or particle concentration) are met. The spray head 510 removes dust, particle deposits, or other contaminants by spraying the front surface 210 of the photovoltaic panel 200. This spraying operation helps to restore the cleanliness of the photovoltaic panel 200 surface, improve its light reception conditions, and thus provide a better foundation for light energy absorption for the next power generation cycle.

[0082] At the same time, by facing the front side 210 of the photovoltaic panel 200 towards the cooling module 500 at night, the direct effects of external environmental factors such as wind and sand erosion, rain erosion or hail impact on the photovoltaic surface can be reduced to a certain extent, which helps to slow down the aging of components and material fatigue process, extend the service life of the photovoltaic panel 200 and enhance its ability to adapt to complex climate environments.

[0083] In some embodiments, reference Figure 2、 Figure 3 , further comprising a drive module 600 for driving the photovoltaic panel 200 to switch between the first state and the second state. The drive module 600 may include an electric push rod, a rotary drive, a hydraulic drive device, or other form of actuator, and is configured to, under the instruction of the control unit (e.g., via a switch element, thereby driving the photovoltaic panel 200 to switch states), flip, rotate, or tilt the photovoltaic panel 200 about the support axis to complete the transition from the first state to the second state, or vice versa.

[0084] Through the above settings, the automatic switching of the posture of the photovoltaic panel 200 can be achieved, so that it can meet the needs of improving cooling efficiency and protective cleaning in different operating stages, thereby helping to extend the service life of the photovoltaic panel 200 components to a certain extent, improving its environmental adaptability, and maintaining stable power generation performance.

[0085] It can be understood that since the photovoltaic panel 200 needs to be placed in contact with the cooling module 500 in the first state in order to achieve the cooling operation, and in the second state it needs to be spaced apart from the cooling module 500 so that the front side 210 faces the cooling module 500 for protection or cleaning, in the process of state switching, it is preferably first driven away from the cooling module 500 to make it out of the contact state, and then perform a posture adjustment operation, such as flipping or rotating around the support axis, to complete the switch from the first state to the second state.

[0086] Similarly, in the process of recovering from the second state to the first state, the photovoltaic panel 200 may be rotated to the target posture first, and then driven close to the cooling module 500 and in contact therewith to ensure cooling efficiency and structural stability.

[0087] The above-mentioned step-by-step drive control is helpful in avoiding structural interference or panel damage caused by direct rotation, helps to improve the reliability of posture switching and the stability of operation, and further ensures the functional realization of the photovoltaic panel 200 in different operation stages.

[0088] In some embodiments, reference Figure 2 、 Figure 4 The back surface 220 is provided with a cooling portion 232. When the photovoltaic panel 200 is in the first state, a cooling channel 531c is formed between the back surface 220 and the cooling module 500. At least a portion of the cooling portion 232 is located within the cooling channel 531c. When the photovoltaic panel 200 is in the first state, its back surface 220 is in contact with the cooling module 500. At this time, a cooling channel 531c for the flow of coolant is formed between the back surface 220 and the cooling module 500. At least a portion of the cooling portion 232 is located within the cooling channel 531c.

[0089] Preferably, the cooling portion 232 may include a number of raised ribs, heat conducting plates, or heat exchange fins to increase the heat exchange area and guide the coolant to form a turbulent or directional flow within the cooling channel 531c, thereby enhancing heat exchange efficiency. With this structure, the coolant fully contacts the cooling portion 232 while flowing through the cooling channel 531c, which can improve the heat dissipation capacity of the photovoltaic panel 200 to a certain extent, allowing the photovoltaic panel 200 to maintain a relatively suitable operating temperature range.

[0090] By disposing the cooling portion 232 on the back surface 220 and positioning it at least partially within the cooling channel 531c, the functional integration and thermal management capabilities of the cooling channel are improved. This also facilitates subsequent adjustment of the channel resistance and heat exchange efficiency through structural optimization, thereby improving the operating performance and adaptability of the entire system. This solves the problem of low cooling efficiency when the back surface 220 and the cooling module 500 are simply bonded.

[0091] In some embodiments, reference Figure 1 、 Figure 2 The cooling module 500, the photovoltaic panel 200, and the cogeneration unit 300 are sequentially connected in series via the cooling liquid pipe 520, so that the cooling liquid flows through the photovoltaic panel 200 and the cogeneration unit 300 in sequence and is then cooled by the cooling module 500. Specifically, the cooling liquid first flows through the photovoltaic panel 200, cooling the photovoltaic panel 200 by absorbing the heat generated by the photovoltaic panel 200. The cooling liquid then continues to flow to the cogeneration unit 300, exchanges heat with the relevant components of the cogeneration unit 300, and finally flows back to the cooling module 500 for heat dissipation. This series structure is beneficial in that a single cooling cycle system is used to complete the temperature regulation of the photovoltaic panel 200 and the cogeneration unit 300, simplifying the system structure. At the same time, it can achieve a reasonable distribution of the cooling liquid temperature under most operating conditions, which helps to improve the overall cooling efficiency and stable operation of the system.

[0092] In some embodiments, reference Figure 2 、 Figure 4The cooling module 500 includes a diverter plate 530 provided on the support module 100, and a cooling plate 230 is provided on the back 220. When the photovoltaic panel 200 is in the first state, the diverter plate 530 and the cooling plate 230 are attached to each other and define a cooling channel 531c. The cooling portion 232 is integrally provided with the cooling plate 230. When the photovoltaic panel 200 is in the first state, the diverter plate 530 and the cooling plate 230 are attached to each other and jointly define a cooling channel 531c, which provides a channel for the coolant to achieve effective cooling of the back 220 of the photovoltaic panel 200. Through the cooperation between the diverter plate 530 and the cooling plate 230, the flow path of the coolant can be optimized to a certain extent, the cooling efficiency can be improved, and it is beneficial to maintain the photovoltaic panel 200 working within an appropriate temperature range, thereby promoting the stability of power generation efficiency and the reliable operation of the system. The diverter plate 530 facilitates the formation of the cooling portion 232.

[0093] In some embodiments, reference Figure 2 、 Figure 4 The photovoltaic panel 200 includes a plurality of heat-conducting columns 231, one end of which is located at the front surface 210 and the other end is located at the back surface 220. This structural arrangement helps to achieve bidirectional heat conduction regulation under different operating conditions: under nighttime operating conditions, when the front surface 210 of the photovoltaic panel 200 faces the cooling module 500, since the coolant may have a certain temperature, the heat-conducting columns 231 can guide the heat on the front surface 210 side to the back surface 220, thereby preventing the back surface 220 from freezing or thermal stress concentration due to the low temperature environment, thereby alleviating material thermal fatigue to a certain extent and enhancing the environmental adaptability of the photovoltaic module; under daytime operating conditions, when the front surface 210 of the photovoltaic panel 200 receives sunlight, the heat-conducting columns 231 can also guide part of the heat absorbed by the front surface 210 to the back surface 220 area, and the cooling module 500 attached to the back surface 220 performs heat exchange and heat dissipation processing, thereby helping to suppress the excessive surface temperature of the photovoltaic panel 200 and maintaining its operating temperature stability and power generation efficiency. The heat-conducting pillars 231 may be made of metal or composite materials with high thermal conductivity to enhance heat transfer performance while maintaining the mechanical stability of the overall structure of the photovoltaic panel 200 .

[0094] In some embodiments, reference Figure 3 、 Figure 5When the photovoltaic panel 200 is in the second state, the diverter plate 530 and the cooling plate 230 are spaced apart. That is, the photovoltaic panel 200 and the cooling module 500 are no longer directly attached to each other. This structural design forms a space area between the cooling module 500 and the photovoltaic panel 200, which facilitates the nozzle 510 in the cooling module 500 to spray the front 210 of the photovoltaic panel 200, further assisting in completing the cleaning and protection functions. In this state, the front 210 of the photovoltaic panel 200 faces the cooling module 500, which helps to perform front 210 cleaning, thermal buffering and other operations on the photovoltaic module during non-power generation periods, thereby reducing the impact of external factors such as wind, sand, frost, and hail on the photovoltaic panel 200 to a certain extent, and providing favorable guarantees for maintaining good light reception conditions for the next power generation cycle. The setting of this spacing structure also facilitates the atomization and uniform distribution of the liquid generated by the nozzle 510, thereby enhancing the cleaning effect.

[0095] In some embodiments, reference Figure 2 、 Figure 4 The support module 100 is slidably provided with a support base 110, and the photovoltaic panel 200 is rotatably provided on the support base 110. The driving module 600 includes a first driving device 610 and a second driving device 620. The first driving device 610 is used to drive the support base 110 to slide in a direction toward or away from the diverter plate 530, and the second driving device 620 is used to drive the photovoltaic panel 200 to rotate relative to the support base 110. The first driving device 610 is used to drive the support base 110 to slide relative to the support module 100 in a direction toward or away from the diverter plate 530, thereby adjusting the overall position of the photovoltaic panel 200. The second driving device 620 is used to drive the photovoltaic panel 200 to rotate relative to the support base 110, thereby achieving the posture switching of the photovoltaic panel 200 between the first state and the second state.

[0096] Specifically, when switching from the first state to the second state, the first drive device 610 first drives the support base 110 away from the diverter plate 530, causing the photovoltaic panel 200 to break away from the cooling module 500. The second drive device 620 then rotates the photovoltaic panel 200 so that its front face 210 faces the cooling module 500 and is at a set angle, completing the switching process. This step-by-step structural switching mechanism helps avoid structural interference or component damage caused by direct rotation, and improves the stability and reliability of the switching process, thereby providing beneficial support for the long-term operation of the system.

[0097] In some embodiments, reference Figure 2 、 Figure 4The cooling plate 230 is connected to the heat-conducting posts 231. Specifically, the heat-conducting posts 231 are disposed within the photovoltaic panel 200, with one end extending to the front surface 210 of the photovoltaic panel 200 and the other end extending to the back surface 220. These posts are then thermally connected to the cooling plate 230. This structure allows solar radiation heat received by the front surface 210 of the photovoltaic panel 200 to be transferred to the cooling plate 230 via the heat-conducting posts 231, where the heat is then removed by the cooling plate 230 through the coolant.

[0098] In some embodiments, the diverter plate 530 is provided with a recessed groove 531. When the photovoltaic panel 200 is in the first state, the recessed groove 531 cooperates with the cooling plate 230 to form a cooling channel 531c, and the nozzle 510 is located in the recessed groove 531. Specifically, the recessed groove 531 is used to provide a flow channel for the coolant. When the photovoltaic panel 200 is in the first state, its back surface 220 is in contact with the cooling module 500 provided with the cooling plate 230, and a closed or semi-closed cooling channel 531c is formed between the recessed groove 531 and the cooling plate 230, allowing the coolant to flow along a predetermined path within the channel, thereby effectively cooling the back surface 220 of the photovoltaic panel 200.

[0099] The nozzle 510 is located in the recessed groove 531 and can perform liquid spraying operations under set conditions according to the operating status of the system. For example, at night, when the photovoltaic panel 200 is turned into a non-working state, the front 210 thereof can be cleaned or sprayed with heat by the nozzle 510. Since the nozzle 510 is arranged in the recessed groove 531, its installation position is more concealed, which can avoid the direct influence of adverse factors such as wind, sand, rain and so on to a certain extent, and enhance the structural stability and service life of the nozzle 510. In addition, arranging the nozzle 510 near the main channel of the coolant also helps in the distribution and management of the coolant and improves the overall cooling and maintenance efficiency of the system.

[0100] In some embodiments, reference Figure 2 、 Figure 4 The diverter plate 530 is slidably provided with a slider 540, which slides along the depth direction of the recessed groove 531. In some embodiments, when the photovoltaic panel 200 is in the second state, the slider 540 is located at the notch side of the recessed groove 531, and the slider 540 and the recessed groove 531 cooperate to form a cooling channel 531c. When the photovoltaic panel 200 is in the first state, the slider 540 is located at the bottom side of the recessed groove 531. In some embodiments, when the photovoltaic panel 200 is in the first state, the cooling portion 232 is configured to abut against the slider 540 to push the slider 540 to slide to the bottom side of the recessed groove 531.

[0101] The slidable structure of the slider 540 helps to adjust the on / off state of the cooling channel 531c and its fluid contact structure under different working conditions.

[0102] Specifically, during nighttime operation, the photovoltaic panel 200 is in a non-generating state, with its front face 210 facing the cooling module 500. Under the pressure of the coolant flow or the action of the elastic member 550, the slider 540 can slide to the notch of the recessed groove 531 and close the notch, thereby forming a relatively closed cooling channel 531c between the recessed groove 531 and the cooling plate 230. This facilitates the flow of coolant along a predetermined path and improves heat exchange efficiency. This cooling channel 531c can be used to conduct waste heat from the cogeneration unit 300, thereby achieving temperature regulation of the cooling module 500 or the front face 210 of the photovoltaic panel 200.

[0103] During the day, the photovoltaic panel 200 flips to the first position, with its back side 220 facing the cooling module 500. The cooling portion 232 on the back side 220 squeezes or pushes the slider 540 toward the bottom of the recessed groove 531, placing the slider 540 at the bottom of the groove. At this point, the notch of the recessed groove 531 is open, allowing the coolant to directly contact the cooling plate 230 and the cooling portion 232, thereby increasing the heat exchange area and efficiency to a certain extent, and facilitating a strong cooling effect on the back side 220 of the photovoltaic panel 200.

[0104] On the one hand, the slider 540 structure helps to flexibly adjust the cooling channel according to the operating period. On the other hand, it also has certain dust and foreign matter prevention functions, which can reduce the entry of dust or particles into the cooling channel 531c, thereby improving the long-term stability and reliability of the system operation.

[0105] In some embodiments, reference Figure 2 、 Figure 4 The nozzle 510 is mounted on the slider 540. During daytime operation, the slider 540 is located at the bottom of the recessed groove 531. Accordingly, the nozzle 510 is located within the cooling channel 531c, in direct contact with the coolant. It primarily maintains coolant circulation and heat exchange within the cooling channel 531c, and does not perform any spraying operations. In this state, the nozzle 510 is primarily stationary, while also serving as an auxiliary cooling channel element.

[0106] During nighttime operation, the slider 540 slides to the notch of the recessed groove 531. A sealed or semi-sealed coolant chamber is formed between the slider 540 and the bottom of the recessed groove 531, and the nozzle 510 is positioned toward the front surface 210 of the photovoltaic panel 200. Driven by the hydraulic device in the coolant pumping or cooling module 500, the coolant in the chamber acts on the nozzle 510 under a certain pressure, prompting the nozzle 510 to open and spray, thereby spraying the coolant onto the front surface 210 of the photovoltaic panel 200 in a predetermined pattern. This spraying operation can be performed when the photovoltaic panel 200 is not in operation, facilitating the removal of dust, particles, and other deposits adhering to its surface, thereby improving light incidence conditions.

[0107] It can be understood that by adjusting the supply pressure of the coolant or controlling the valve opening, the spray state of the nozzle 510 can be flexibly controlled to achieve intermittent, directional or pulsed spray cleaning operations, thereby improving the operating efficiency of the photovoltaic module and the overall maintainability of the system without increasing the complexity of the additional mechanism.

[0108] In some embodiments, reference Figure 2 、 Figure 4 The liquid inlet of the nozzle 510 is located on the side of the slider 540 facing the bottom of the recessed groove 531. This structural arrangement enables the nozzle 510 to directly establish a fluid connection with the coolant in the bottom area of ​​the recessed groove 531 when the slider 540 is located at the notch of the recessed groove 531, thereby realizing the automatic liquid supply function of the nozzle 510.

[0109] This structural design facilitates direct delivery of coolant to the interior of the nozzle 510 through the inner cavity 531d of the recessed groove 531 during operation, eliminating the need for additional piping. This reduces the complexity and flow resistance of the liquid supply path. Furthermore, when the slider 540 is in the spraying position (i.e., near the notch of the recessed groove 531), the liquid inlet of the nozzle 510 faces the liquid area at the bottom of the recessed groove 531. Under the influence of the static pressure or pump pressure of the liquid, the coolant can be rapidly injected into the nozzle 510, completing the spraying operation.

[0110] This setting method not only simplifies the connection between the nozzle 510 and the coolant in structure, but also provides higher response efficiency in functional implementation, which is conducive to quickly completing the surface cleaning of the photovoltaic panel 200 in a specific period of time and improving the system's degree of automation and operational reliability.

[0111] In some embodiments, reference Figure 2 、 Figure 4 An elastic member 550 is disposed between the slider 540 and the diverter plate 530. The elastic member 550 is used to slide the slider 540 to the open side of the recessed groove 531. This structural arrangement facilitates, without the need for an additional driving device, the return force of the elastic member 550 (e.g., a spring, elastic gasket, etc.) to return the slider 540 to the notch area of ​​the recessed groove 531 under a predetermined state. This allows the nozzle 510 to return to a suitable position for cleaning at night or when the photovoltaic panel 200 is not in operation, and to form a stable cooling channel 531c in conjunction with the recessed groove 531.

[0112] Furthermore, when the system enters daytime operation, the thrust generated by the contact between the cooling portion 232 and the slider 540 overcomes the restoring force of the elastic member 550, causing the slider 540 to slide to the bottom of the recessed groove 531, thereby switching the position of the nozzle 510 and the cooling path. The elastic member 550 helps improve the adaptive adjustment capability and operational stability of the overall structure while reducing the complexity of the active control components.

[0113] In some embodiments, reference Figure 4 、 Figure 5 The recessed groove 531 is provided with a positive pressure port 531a and a pressure relief port 531b. When the slider 540 is located at the recessed groove 531, a cavity 531d is formed between the slider 540 and the bottom of the recessed groove 531. The positive pressure port 531a is in communication with the cavity 531d, while the pressure relief port 531b is partially blocked by the slider 540. When the slider 540 slides to the bottom of the recessed groove 531, the pressure relief port 531b and the positive pressure port 531a are both located on the side of the slider 540 facing away from the bottom of the recessed groove 531. This structure helps to increase the pressure in the cavity 531d, thereby promoting more efficient spraying of coolant through the nozzle 510. Conversely, when the slider 540 slides to the bottom side of the recessed groove 531, the pressure relief port 531b and the positive pressure port 531a are both located on the side of the slider 540 away from the bottom of the recessed groove 531, so that the coolant can flow freely out of the recessed groove 531 to avoid pressure accumulation.

[0114] This arrangement facilitates controlling the coolant pressure by adjusting the position of slider 540, thereby switching between the spray function of nozzle 510 and cooling channel 531c, and facilitating effective cooling and cleaning of photovoltaic panels 200 under different operating conditions. Partially blocking pressure relief port 531b with slider 540 helps maintain a high pressure when coolant is sprayed, improving spray efficiency while also preventing excessive pressure from affecting flow stability during cooling.

[0115] In some embodiments, the notch of the recessed groove 531 is provided with a rib 560. The rib 560 is configured to abut against the side of the slider 540 facing away from the bottom of the recessed groove 531 to limit the sliding range of the slider 540 within the recessed groove 531. A first seal 561 is provided between the slider 540 and the rib 560. This seal helps to improve the sealing between the slider 540 and the rib 560, reducing the risk of coolant leakage. The provision of the rib 560 not only limits the sliding travel of the slider 540, preventing the slider 540 from moving outside the predetermined range, but also ensures the stability and sealing effect of the slider 540 when switching between different positions, thereby improving the overall performance and reliability of the cooling module 500.

[0116] In some embodiments, a second seal 541 is provided on the slider 540 opposite the pressure relief port 531b to partially block the pressure relief port 531b when the slider 540 is positioned within the recessed groove 531. This seal can adjust the pressure distribution within the cavity 531d within the recessed groove 531 to a certain extent, allowing coolant to be ejected through the nozzle 510 under controlled pressure, thereby improving the stability and effectiveness of coolant injection. This structural design facilitates flexible control of coolant flow and injection conditions, enhancing the system's cooling and cleaning capabilities.

[0117] In some embodiments, reference Figure 1 、 Figure 6 The cooling module 500 further includes a heat exchange unit 570 and a hot water tank 580. The heat exchange unit 570 is used to exchange heat with the photovoltaic panel 200 and the cogeneration unit 300, and is used to heat the water in the hot water tank 580. The nozzle 510 is connected to the heat exchange unit 570. This is beneficial for recovering waste heat generated during system operation and transferring this waste heat to the water in the hot water tank 580, thereby heating the water in the hot water tank 580.

[0118] The water in the hot water tank 580 can not only be used by users as hot water for living or production, but also, through the heat exchange process with the heat exchange unit 570, the water can also have a certain degree of cooling effect on the cooling module 500, which is beneficial to maintaining the temperature stability of the cooling module 500, thereby promoting the thermal energy management and operation efficiency of the entire system.

[0119] In some embodiments, reference Figure 6 The heat exchange unit 570 is provided with a first inlet 571, a second inlet 572, a first outlet 573, and a second outlet 574. The photovoltaic panel 200 and the cogeneration unit 300 are connected in series through the coolant pipe 520 and then communicated with the first inlet 571 and the second inlet 572 to form a first heat exchange circuit. The coolant in the first heat exchange circuit flows through the photovoltaic panel 200 and the cogeneration unit 300 in sequence, realizing cooling and heat energy recovery for both. The hot water tank 580 is connected with the second inlet 572 and the second outlet 574 to form a second heat exchange circuit. The water in the hot water tank 580 absorbs heat from the first heat exchange circuit through this circuit to achieve heating of the water in the tank. This structure is conducive to the effective utilization and distribution of thermal energy in the system and improves energy utilization efficiency.

[0121] During the day, the photovoltaic panel 200 is in the first state, the cogeneration unit 300 is turned off, the photovoltaic panel 200 generates electricity and stores the output electricity in the energy storage device 400, and the photovoltaic panel 200 is cooled by the cooling module 500 and the cogeneration unit 300;

[0122] At night, the photovoltaic panel 200 is in the second state, the cogeneration unit 300 is turned on, and the nozzle 510 sprays coolant toward the front surface 210 to clean the surface for a set time;

[0123] After the front surface 210 is cleaned, the spray pressure of the nozzle 510 is adjusted to a preset range so that the coolant does not contact the front surface 210 to keep the photovoltaic panel 200 warm.
