The embodiments of the present application will be described in detail below with reference to the drawings.

[0054] Solar energy has the advantages of being pollution-free, having no regional restrictions, and being inexhaustible. Therefore, at present, photovoltaic power generation using solar energy has become one of the mainstream ways of clean energy development. However, during the power generation process of photovoltaic modules, waste heat will be generated due to direct sunlight and energy conversion. As the temperature of the photovoltaic module increases, its power generation efficiency will decrease. According to the prior art, for every 1 degree Celsius increase in temperature, the power generation efficiency of the photovoltaic panel will decrease by about 0.4%. In summer, the maximum temperature of the photovoltaic module can reach above 75 degrees Celsius, and the actual power generation power of the photovoltaic module decreases by 25% to 30%. In addition, continuous high temperature will also cause the photovoltaic module to age and its lifespan to decrease, invisibly increasing the investment and operation and maintenance costs of the photovoltaic power station.

[0055] Based on the above technical problems, the embodiments of the present application provide a photovoltaic power station recycling system and a photovoltaic power station. In this technical solution, the photovoltaic power station recycling system is used for photovoltaic modules, and it includes a water supply component and a conversion component. The water supply component includes a collection member, a water storage member, and a water supply pipeline. The collection member is used to be arranged on one side of the photovoltaic module to collect rainwater on the photovoltaic module. The water storage member is connected to the collection member. Part of the water supply pipeline is used to be arranged on the photovoltaic module. The water supply pipeline communicates the water storage member and the conversion component. The water storage member is used to supply water to the water supply pipeline so that the rainwater absorbs the heat of the photovoltaic module. The conversion component is used to be connected to a heat-using member and supply water vapor to the heat-using member. The conversion component is configured to receive the rainwater after absorbing heat and convert the heat of the rainwater into water vapor. By providing the collection member, the water storage member, and the water supply pipeline, the rainwater on the photovoltaic module is collected, and the photovoltaic module is cooled by using the rainwater. The rainwater after absorbing the heat of the photovoltaic module realizes heat conversion in the conversion component, so that the conversion component generates water vapor for the use of the heat-using member.

[0056] In this way, not only can the rainwater resources be fully utilized, the temperature of the photovoltaic module can be reduced, and the power generation efficiency of the photovoltaic module can be improved. At the same time, the heat generated by the photovoltaic module can be used to heat the rainwater, and the conversion component converts this part of the heat into water vapor for the use of the heat-using member, which can fully utilize the heat generated by the photovoltaic module and further improve the resource utilization rate.

[0057] It should be noted that Figures 1 to 3 schematically shows a simplified schematic diagram of each component in the photovoltaic power station recycling system and the photovoltaic power station. The specific structure of the remaining components in the photovoltaic power station recycling system and the photovoltaic power station is not limited to Figures 1 to 3 the illustration of Figure 4 schematically shows a simplified control flow chart of the control system, and the specific control flow of the control system is not limited to Figure 4 the illustration of

[0058] The following will combine the drawings and specific embodiments to elaborate on the present application in detail:

[0059] Referring to Figure 1 、 Figure 2 and Figure 3 shown, a photovoltaic power station recycling system provided by the embodiments of the present application is used for photovoltaic module 100 and includes a water supply component 200 and a conversion component 300.

[0060] The water supply component 200 includes a collection member (not shown in the figure), a water storage member 210, and a water supply pipeline 220.

[0061] The collecting member is configured to be disposed on one side of the photovoltaic module 100 to collect rainwater on the photovoltaic module 100. The collecting member herein may be a rainwater diversion trough, which is a related technology in this field and only needs to be able to collect the rainwater on the photovoltaic module 100. The embodiments of the present application do not make specific limitations thereto.

[0062] The water storage member 210 is connected to the collecting member to store the rainwater collected by the collecting member. The water storage member 210 herein may be one of a water storage tank and a water storage pool. The embodiments of the present application do not limit the specific structure of the water storage member 210.

[0063] Part of the water supply pipeline 220 is configured to be disposed on the photovoltaic module 100. The water supply pipeline 220 communicates the water storage member 210 and the conversion module 300. The water storage member 210 is used to supply water to the water supply pipeline 220 to absorb the heat of the photovoltaic module 100.

[0064] In specific implementation, the water supply pipeline 220 may be laid in a serpentine shape on the backlight surface of the photovoltaic module 100, which not only does not affect the photovoltaic module 100 to absorb light energy, but also can cool the photovoltaic module 100.

[0065] The conversion module 300 is configured to be connected to the heat-using member 10. The conversion module 300 is configured to receive the rainwater after absorbing heat and convert the heat of the rainwater into water vapor for use by the heat-using member 10.

[0066] The heat-using member 10 herein may be any form of heat-using member 10, such as a water heater for residents, a heater in a greenhouse, etc. The specific form of the heat-using member 10 can be selected according to actual needs.

[0067] By providing the collecting member, the water storage member 210 and the water supply pipeline 220, the rainwater on the photovoltaic module 100 is collected, and the photovoltaic module 100 is cooled by using the rainwater. The rainwater after absorbing the waste heat of the photovoltaic module 100 is vaporized into water vapor by the conversion module 300 for use by the heat-using member 10. It can not only make full use of rainwater resources, achieve the cooling of the photovoltaic module 100, improve the power generation efficiency of the photovoltaic module 100, but also use the heat of the photovoltaic module to heat the rainwater for use by the heat-using member 10, further improving the resource utilization rate.

[0068] Herein, by heating to generate water vapor and then transporting the water vapor with temperature to the heat-using member 10, it has the characteristics of being fast and convenient compared with directly transporting the heated rainwater. The water vapor has a fast transmission speed, a large temperature range that can be increased, and also carries a large amount of heat, which can improve the heat transmission effect.

[0069] It should be noted that the water storage member 210 can not only collect rainwater on the photovoltaic module 100, but also has an inlet connected to the tap water system, and tap water can be introduced into the water storage member 210 to ensure that the water storage member 210 supplies water to the water supply pipeline 220.

[0070] The photovoltaic module 100 is an existing technology in the related field, and the embodiments of the present application do not make specific limitations on this.

[0071] In a possible implementation manner, the conversion assembly 300 includes a generator 310 and an absorber 320.

[0072] Both the generator 310 and the absorber 320 contain a first refrigerant, and the generator 310 is connected to the absorber 320 to enable the first refrigerant to circulate between the generator 310 and the absorber 320.

[0073] The generator 310 is used to connect to the heat-using member 10.

[0074] The generator 310 is configured to heat the first refrigerant using the heat of rainwater to generate water vapor and transport the water vapor to the heat-using member 10 for use.

[0075] The absorber 320 is used to connect to the heat-using member 10.

[0076] The absorber 320 is configured to receive the liquid water condensed from the water vapor on the heat-using member 10, and the liquid water is absorbed by the first refrigerant in the absorber 320.

[0077] In the above embodiment, the rainwater heated by the heat of the photovoltaic module is transported to the generator 310. The first refrigerant in the generator 310 generates water vapor under the heating of the rainwater. This part of the water vapor is used by the heat-using member 10. After the water vapor releases heat at the heat-using member 10, it will condense into low-temperature and high-pressure liquid water. This part of the liquid water is transported back to the absorber 320 to complete the cycle in the absorber 320 and the generator 310. By utilizing the change in the physical properties of water vapor, the absorption and release of heat can be realized, and the heat transfer effect can be improved.

[0078] In a possible implementation manner, an evaporator 330 is further included.

[0079] The evaporator 330 contains a second refrigerant.

[0080] The evaporator 330 is used to communicate with the heat-using member 10 to receive liquid water.

[0081] The evaporator 330 is used to connect to the cooling member 20. The liquid water vaporizes and absorbs heat in the evaporator 330 to cool the second refrigerant, and the cooled second refrigerant is used to cool the cooling member 20.

[0082] The evaporator 330 is connected to the absorber 320 to deliver the vaporized liquid water to the absorber 320.

[0083] In the above embodiment, the liquid water condensed at the heating element 10 is delivered to the evaporator 330. After that, it rapidly expands and vaporizes in the evaporator 330, forming water vapor at low temperature and high pressure. During this process, a large amount of heat of the second refrigerant in the evaporator 330 is absorbed by the rapidly expanding and vaporizing liquid water, so as to achieve the purpose of cooling the second refrigerant. The evaporator 330 is connected to the cooling element 20 to deliver the second refrigerant to the cooling element 20, realizing the cooling of the cooling element 20. After the second refrigerant absorbs heat at the cooling element 20, it flows back to the evaporator 330 again, completing the cycle in the evaporator 330 and the cooling element 20.

[0084] Here, the cooling element 20 can be a low-temperature storage device for storing fruits, vegetables, etc., or other electronic devices that need to be cooled. The specific structure of the cooling element 20 is not limited in the embodiment of the present application.

[0085] In the above implementation manner, the water vapor at low temperature and high pressure enters the absorber 320 and is absorbed by the first refrigerant in the absorber 320. The above implementation manner can realize the cooling of the cooling element 20 and improve the practicability.

[0086] In a possible implementation manner, the first refrigerant is a lithium bromide solution, and the second refrigerant is chilled water.

[0087] In the above embodiment, due to its unique physical and chemical properties, the lithium bromide solution is widely used as one of the industrial absorption refrigerants. In lithium bromide absorption refrigeration, water is used as the refrigerant and lithium bromide is used as the absorbent.

[0088] Since the boiling point of the lithium bromide aqueous solution itself is very high and it is extremely difficult to volatilize, the vapor on the liquid surface of the lithium bromide saturated solution can be considered as pure water vapor; at a certain temperature, the saturated partial pressure of water vapor on the liquid surface of the lithium bromide aqueous solution is less than the saturated partial pressure of pure water; and the higher the concentration, the smaller the saturated partial pressure of water vapor on the liquid surface. Therefore, under the same temperature conditions, the higher the concentration of the lithium bromide aqueous solution, the stronger its ability to absorb water. This is the reason for using lithium bromide as the absorbent and water as the refrigerant. Generally, the heat source temperature of lithium bromide absorption refrigeration should be above 65 degrees Celsius.

[0089] Specifically, it is learned with reference to Figure 1 and Figure 3As shown, the absorber 320 is used to receive the concentrated lithium bromide solution and mix it with the water vapor delivered by the evaporator 330 to form a dilute lithium bromide solution. The dilute lithium bromide solution is transported to the generator 310, where it is heated by the heated rainwater. The water in the concentrated lithium bromide solution evaporates to form water vapor. Due to the lack of water in the dilute lithium bromide solution, the dilute lithium bromide solution becomes a concentrated lithium bromide solution. By using the lithium bromide solution, the evaporation of water can be accelerated, improving the effect of generating water vapor.

[0090] In a possible implementation, the water supply assembly 200 further includes a filter member 230.

[0091] The filter member 230 is used to connect the water storage member 210 and the collection member. Specifically, the filter member 230 can be a filter net or a water purification and softening device. Of course, it can also be a combination of a filter net and a water purification and softening device. In the above embodiment, by setting the filter member 230, a large amount of impurities in the rainwater can be filtered, effectively avoiding the blockage of the water storage tank and the water supply pipeline 220, extending the service life, and reducing the maintenance cost.

[0092] In a possible implementation, the filter member 230 is used to connect the collection member and the cooling member 20 to cool the cooling member 20. In this way, the filtered rainwater can also be directly used as cooling water for the cooling member 20. Further improving the utilization rate of rainwater.

[0093] In a possible implementation, it further includes a control assembly 400.

[0094] The control assembly 400 is electrically connected to both the water storage member 210 and the photovoltaic module 100.

[0095] The control assembly 400 is configured to detect the temperature of the photovoltaic module 100. When the temperature is greater than or equal to the first preset value, it controls the water storage member 210 to open to supply water to the water supply pipeline 220 to cool the photovoltaic module 100.

[0096] In the above embodiment, by setting the control assembly 400, the opening and closing of the water storage member 210 can be controlled. Specifically, as shown in Figure 2 As shown, there is a water pump 211 in the water storage member 210, and an electric control switch 221 is provided on the water supply pipeline 220. The water pump 211 in the water storage member 210 and the electric control switch 221 are both electrically connected to the control assembly 400. When the temperature of the photovoltaic module 100 is greater than or equal to the first preset temperature, the control assembly 400 controls the electric control switch 221 and the water pump 211 in the water storage member 210 to be turned on simultaneously to supply water into the water supply pipeline 220, realizing the cooling of the photovoltaic module 100 by the water supply pipeline 220.

[0097] Specifically, it further includes at least one temperature sensor 500 which is arranged on the photovoltaic module 100 to detect the temperature value of the photovoltaic module 100. The first preset value is set to 40 degrees Celsius. When the temperature of the photovoltaic module 100 is greater than or equal to 40 degrees Celsius, its power generation efficiency is significantly reduced. At this time, the electric control switch 221 and the water pump 211 are turned on to cool the photovoltaic module 100. By setting the control system, it is possible to control the optimal timing to cool the photovoltaic module 100, avoiding unnecessary energy consumption caused by continuous cooling of the photovoltaic module 100, and further having the effect of improving the resource utilization rate.

[0098] In a possible implementation manner, the control component 400 is electrically connected to the conversion component 300.

[0099] The control component 400 is configured to control the conversion component 300 to turn on when the temperature is greater than or equal to the second preset value, and the second preset value is greater than the first preset value.

[0100] Specifically, in implementation, the absorber 320 is provided with a solution pump 321 which is electrically connected to the control component 400. When the temperature of the photovoltaic module 100 is greater than or equal to the second preset value, the solution pump 321 is controlled to turn on. The solution pump 321 can transport the dilute lithium bromide solution in the absorber 320 to the generator 310, thereby realizing the circulation of the dilute lithium bromide solution and the concentrated lithium bromide solution between the generator 310 and the absorber 320. According to the prior art, the heat source temperature for lithium bromide absorption refrigeration should be above 65 degrees Celsius, and at this time, the conversion efficiency of the lithium bromide solution is better.

[0101] In a possible implementation manner, it further includes an energy storage component 600.

[0102] The energy storage component 600 is used to be electrically connected to the photovoltaic module 100 to store the electric energy of the photovoltaic module 100.

[0103] The water supply pipeline 220 is simultaneously arranged on the photovoltaic module 100 and the energy storage component 600.

[0104] It should be explained here that due to the unstable power generation characteristics of the photovoltaic module 100, which has a large impact on the power grid, energy storage facilities are usually built in supporting when constructing a photovoltaic power station at present. At the present stage, energy storage batteries are mainly used. However, if the temperature of the energy storage battery is too high, the service life of the energy storage battery will be greatly reduced. According to research, when the temperature exceeds 40 degrees Celsius, for every 1-degree increase, the service life of the energy storage battery will be reduced by 1%. If the temperature rises in a closed environment, the situation will be more obvious. Moreover, a large amount of heat will also be generated during the charging and discharging process of the energy storage battery, which also poses a safety hazard. Therefore, by setting the energy storage component 600 and using the water supply pipeline 220 to cool the photovoltaic module 100 and the energy storage component 600 at the same time, on the one hand, it can alleviate the impact of the photovoltaic module 100 on the power grid, and on the other hand, it can also improve the working efficiency of the energy storage component 600, ensure the normal operation of the photovoltaic module 100 and the energy storage component 600, and reduce the operation and maintenance costs. The energy storage component 600 here can be an energy storage battery, and of course, it can also be other forms of batteries. The specific structure of the energy storage component 600 in this application embodiment is not limited.

[0105] The embodiment of the present application also provides a photovoltaic power station, including the above heat recovery system and at least one photovoltaic module 100. The photovoltaic power station recycling system is arranged on the photovoltaic module 100. Specifically, the photovoltaic power station recycling system can be connected to a plurality of photovoltaic modules 100 to improve the working effect of the photovoltaic power station recycling system.

[0106] Among them, the specific structure of the photovoltaic power station recycling system has been described above and will not be elaborated here. The photovoltaic power station provided with the above photovoltaic power station recycling system can solve the problem that the heat generated by the photovoltaic module 100 affects the power generation efficiency, and at the same time improve the resource utilization rate. It can not only improve the utilization rate of rainwater resources, but also improve the energy utilization rate of the part of the heat generated by the photovoltaic module.

[0107] The implementation principle of a photovoltaic power station recycling system and a photovoltaic power station in an embodiment of the present application is as follows: The photovoltaic power station recycling system is used for photovoltaic module 100, and it includes a water supply component 200 and a conversion component 300. The water supply component 200 includes a collection member, a water storage member 210, and a water supply pipeline 220. The collection member is used to be arranged on one side of the photovoltaic module 100 to collect rainwater on the photovoltaic module 100. The water storage member 210 is connected to the collection member. Part of the water supply pipeline 220 is used to be arranged on the photovoltaic module 100. The water supply pipeline 220 communicates the water storage member 210 and the conversion component 300. The water storage member 210 is used to supply water to the water supply pipeline 220 so that the rainwater absorbs the heat of the photovoltaic module 100. The conversion component 300 is used to be connected to a heat-using member 10 and supply steam to the heat-using member 10. The conversion component 300 is configured to receive the rainwater after absorbing heat and convert the heat of the rainwater into steam. By arranging the collection member, the water storage member 210, and the water supply pipeline 220, the rainwater on the photovoltaic module 100 is collected, and the photovoltaic module 100 is cooled by using the rainwater. The rainwater after absorbing the heat of the photovoltaic module 100 realizes heat conversion in the conversion component 300, so that the conversion component 300 generates steam for the use of the heat-using member 10.

[0108] In this way, not only can rainwater resources be fully utilized to cool the photovoltaic module 100 and improve the power generation efficiency of the photovoltaic module 100, but also the heat generated by the photovoltaic module 100 can be used to heat the rainwater.
