DETAILED DESCRIPTION

[0053] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0054] Solar energy has the advantages of being pollution-free, not limited by geographical regions, and inexhaustible. Therefore, photovoltaic power generation using solar energy has become one of the mainstream ways of developing clean energy. However, photovoltaic modules will generate waste heat during the power generation process due to direct sunlight and energy conversion. As the temperature of photovoltaic modules increases, their power generation efficiency will decrease. According to existing technology, for every 1 degree Celsius increase in temperature, the power generation efficiency of photovoltaic panels will decrease by about 0.4%. In summer, the maximum temperature of photovoltaic modules can reach more than 75 degrees Celsius, and the actual power generation of photovoltaic modules will decrease by 25% to 30%. In addition, continuous high temperatures will also cause the aging of photovoltaic modules and shorten their lifespan, which will invisibly increase the investment and operation and maintenance costs of photovoltaic power stations.

[0055] Based on the above technical problems, the embodiment of the present application provides a photovoltaic power station recycling system and a photovoltaic power station. In the technical scheme, the photovoltaic power station recycling system is used for photovoltaic modules, which includes a water supply component and a conversion component. The water supply component includes a collecting component, a water storage component and a water supply pipeline. The collecting component is used to be arranged on one side of the photovoltaic module to collect rainwater on the photovoltaic module. The water storage component is connected to the collecting component. Part of the water supply pipeline is used to be arranged on the photovoltaic module. The water supply pipeline connects the water storage component and the conversion component. The water storage component 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 connect to the heat-using component and supply water vapor to the heat-using component. The conversion component is configured to receive the rainwater after absorbing the heat and convert the heat of the rainwater into water vapor. By setting the collecting component, the water storage component and the water supply pipeline, the rainwater on the photovoltaic module is collected and the rainwater is used to cool the photovoltaic module. 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 use by the heat-using component.

[0056] In this way, not only can rainwater resources be fully utilized to cool down photovoltaic modules and improve the power generation efficiency of photovoltaic modules, but the heat generated by photovoltaic modules can also be used to heat rainwater. The conversion components convert this part of heat into water vapor for use by heating components, which can fully utilize the heat generated by photovoltaic modules and further improve resource utilization.

[0057] It should be noted that Figures 1 to 3 The schematic diagram of the photovoltaic power station recycling system and the components of the photovoltaic power station is shown. The specific structure of the photovoltaic power station recycling system and the other components of the photovoltaic power station are not limited to Figures 1 to 3 Example of Figure 4 The simplified control flow chart of the control system is shown, and the specific control flow of the control system is not limited to Figure 4 of examples.

[0058] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0059] Reference Figure 1 , Figure 2 and Figure 3 As shown, a photovoltaic power station recycling system provided in an embodiment of the present application is used for a photovoltaic component 100 , including a water supply component 200 and a conversion component 300 .

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

[0061] The collecting member is used to be arranged on one side of the photovoltaic module 100 to collect rainwater on the photovoltaic module 100. The collecting member here can be a rainwater diversion trough, which is a related technology in this field, and only needs to be able to collect rainwater on the photovoltaic module 100, and the embodiment of the present application does not make specific restrictions on this.

[0062] The water storage component 210 is connected to the collecting component to store rainwater collected by the collecting component. The water storage component 210 here can be a water tank or a water reservoir. The embodiment of the present application does not limit the specific structure of the water storage component 210.

[0063] Part of the water supply pipeline 220 is used to be set on the photovoltaic component 100. The water supply pipeline 220 connects the water storage component 210 and the conversion component 300. The water storage component 210 is used to supply water to the water supply pipeline 220 to absorb the heat of the photovoltaic component 100.

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

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

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

[0067] By setting the collecting component, the water storage component 210 and the water supply pipeline 220, rainwater on the photovoltaic module 100 can be collected and used to cool the photovoltaic module 100. The rainwater that absorbs the waste heat of the photovoltaic module 100 is vaporized into water vapor through the conversion component 300 for use by the heat-using component 10. Not only can the 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 of the photovoltaic module can be used to heat the rainwater for use by the heat-using component 10, further improving the resource utilization rate.

[0068] Here, water vapor is generated by heating, and then the heated water vapor is transported to the heating element 10. Compared with directly transporting heated rainwater, it is quick and convenient. The water vapor transmission speed is fast, the temperature range that can be heated is large, and the heat carried is also large, which can improve the effect of heat transfer.

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

[0070] The photovoltaic assembly 100 is a prior art in the relevant field, and the embodiments of the present application do not impose any specific limitation on this.

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

[0072] The generator 310 and the absorber 320 both have the first refrigerant therein, and the generator 310 is in communication with the absorber 320 , so that the first refrigerant circulates in the generator 310 and the absorber 320 .

[0073] The generator 310 is used to be connected to the heating element 10 .

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

[0075] The absorber 320 is used to be connected to the heat-consuming element 10 .

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

[0077] In the above embodiment, 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 for the heat-using element 10. After the water vapor releases the temperature at the heat-using element 10, it will condense into low-temperature and high-pressure liquid water. This part of the liquid water is transported to the absorber 320 again to complete the cycle in the absorber 320 and the generator 310. By utilizing the changes in the physical properties of water vapor to achieve heat absorption and release, the heat transmission effect can be improved.

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

[0079] The evaporator 330 contains the second refrigerant.

[0080] The evaporator 330 is used to communicate with the heating element 10 to receive liquid water.

[0081] The evaporator 330 is used to be connected to the cooling element 20 . Liquid water evaporates in the evaporator 330 to absorb heat so as to cool the second refrigerant, and the cooled second refrigerant is used to cool the cooling element 20 .

[0082] The evaporator 330 is in communication with the absorber 320 to transport the vaporized liquid water to the absorber 320 .

[0083] In the above embodiment, the liquid water condensed at the heating element 10 is transported to the evaporator 330, and then rapidly expands and vaporizes in the evaporator 330 to form low-temperature and high-pressure water vapor. During this process, the second refrigerant in the evaporator 330 absorbs a large amount of heat from the rapidly expanded and vaporized liquid water, thereby achieving the purpose of cooling the second refrigerant. The evaporator 330 is connected to the cooling element 20 to transport the second refrigerant to the cooling element 20 to achieve cooling of the cooling element 20. After absorbing heat at the cooling element 20, the second refrigerant flows back to the evaporator 330 to complete the circulation in the evaporator 330 and the cooling element 20.

[0084] Here, the cooling component 20 may be a low-temperature storage device for storing fruits and vegetables, etc., or may be other electronic equipment that needs to be cooled, etc. The embodiment of the present application does not limit the specific structure of the cooling component 20.

[0085] In the above implementation, low-temperature and high-pressure water vapor enters the absorber 320 and is absorbed by the first refrigerant in the absorber 320. The above implementation can achieve cooling by the cooling element 20, thereby improving practicality.

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

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

[0088] Since lithium bromide aqueous solution itself has a very high boiling point and is extremely difficult to volatilize, the steam on the surface of the saturated lithium bromide solution can be considered to be pure water vapor; at a certain temperature, the saturated partial pressure of water vapor on the 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 surface. Therefore, under the same temperature conditions, the greater the concentration of lithium bromide aqueous solution, the stronger its ability to absorb water. This is why lithium bromide is used as an absorbent and water as a refrigerant. Generally, the temperature of lithium bromide absorbing cooling heat source should be above 65 degrees Celsius.

[0089] Specifically, it is reported that reference Figure 1 and Figure 3As shown, the absorber 320 is used to receive the lithium bromide concentrated solution and merge it with the water vapor delivered by the evaporator 330 to form a lithium bromide dilute solution. The lithium bromide dilute solution is delivered to the generator 310. In the generator 310, the water in the lithium bromide concentrated solution evaporates to form water vapor. Due to the lack of water in the lithium bromide dilute solution, the lithium bromide dilute solution becomes a lithium bromide concentrated solution. By using the lithium bromide solution, the water can evaporate quickly and the effect of generating water vapor can be improved.

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

[0091] The filter element 230 is used to connect the water storage element 210 and the collection element. Specifically, the filter element 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 element 230, a large amount of impurities in 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 maintenance costs.

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

[0093] In a possible implementation manner, a control component 400 is also included.

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

[0095] The control component 400 is configured to detect the temperature of the photovoltaic component 100 , and when the temperature is greater than or equal to a first preset value, control the water storage component 210 to open, so as to supply water to the water supply pipeline 220 to cool the photovoltaic component 100 .

[0096] In the above embodiment, by setting the control assembly 400, it is possible to control the opening and closing of the water storage member 210. Figure 2 As shown, a water pump 211 is provided 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 component 400. When the temperature of the photovoltaic component 100 is greater than or equal to the first preset temperature, the control component 400 controls the electric control switch 221 and the water pump 211 in the water storage member 210 to start at the same time to supply water to the water supply pipeline 220, so as to realize cooling of the photovoltaic component 100 by the water supply pipeline 220.

[0097] Specifically, at least one temperature sensor 500 is further included, and the temperature sensor 500 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 a control system, the photovoltaic module 100 can be cooled at a better time, avoiding unnecessary energy consumption caused by continuous cooling of the photovoltaic module 100, and further having the effect of improving resource utilization.

[0098] In a possible implementation, 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 a second preset value, and the second preset value is greater than the first preset value.

[0100] In specific implementation, the absorber 320 has a solution pump 321, which is electrically connected to the control component 400. When the temperature of the photovoltaic component 100 is greater than or equal to the second preset value, the solution pump 321 is controlled to be turned on, and the solution pump 321 can transport the dilute lithium bromide solution in the absorber 320 to the generator 310, so as to realize the circulation of the dilute lithium bromide solution and the concentrated lithium bromide solution in the generator 310 and the absorber 320. According to the prior art, the temperature of the lithium bromide absorption cooling heat source should be above 65 degrees Celsius, at which time the conversion efficiency of the lithium bromide solution is better.

[0101] In a possible implementation manner, an energy storage component 600 is also included.

[0102] The energy storage element 600 is used to be electrically connected to the photovoltaic assembly 100 to store the electrical energy of the photovoltaic assembly 100 .

[0103] The water supply pipeline 220 is provided on both the photovoltaic assembly 100 and the energy storage component 600 .

[0104] It should be explained here that, due to the unstable characteristics of photovoltaic assembly 100 power generation, it has a great impact on the power grid. At present, energy storage facilities are usually built in conjunction with photovoltaic power stations. At present, energy storage batteries are the main ones. However, if the temperature of the energy storage battery is too high, the life of the energy storage battery will be greatly reduced. According to research, when the temperature exceeds 40 degrees, the life of the energy storage battery will be reduced by 1% for every 1 degree increase in temperature. If the temperature rises in a closed environment, it will be more obvious, and the energy storage battery will also generate a lot of heat during the charging and discharging process, which also poses a safety hazard. For this reason, by setting up an energy storage component 600 and using the water supply pipeline 220 to cool the photovoltaic assembly 100 and the energy storage component 600 at the same time, on the one hand, it can alleviate the impact of the photovoltaic assembly 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 assembly 100 and the energy storage component 600, and reduce the operation and maintenance cost. The energy storage component 600 here can be an energy storage battery, and of course it can also be other forms of batteries. The embodiment of the present application does not limit the specific structure of the energy storage component 600.

[0105] The embodiment of the present application also provides a photovoltaic power station, including the above-mentioned 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 multiple photovoltaic modules 100 to improve the working effect of the photovoltaic power station recycling system.

[0106] The specific structure of the photovoltaic power station recycling system has been described above and will not be repeated here. The photovoltaic power station equipped with the photovoltaic power station recycling system can solve the problem that the heat generated by the photovoltaic module 100 affects the power generation efficiency and 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 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 a photovoltaic module 100, which includes a water supply module 200 and a conversion module 300. The water supply module 200 includes a collecting component, a water storage component 210 and a water supply pipeline 220. The collecting component is used to be arranged on one side of the photovoltaic module 100 to collect rainwater on the photovoltaic module 100. The water storage component 210 is connected to the collecting component. Part of the water supply pipeline 220 is used to be arranged on the photovoltaic module 100. The water supply pipeline 220 connects the water storage component 210 and the conversion component 300. The water storage component 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 the heat-using component 10 and supply water vapor to the heat-using component 10. The conversion component 300 is configured to receive rainwater after absorbing heat and convert the heat of the rainwater into water vapor. By setting up a collecting component, a water storage component 210 and a water supply pipeline 220, rainwater on the photovoltaic component 100 can be collected and used to cool the photovoltaic component 100. The rainwater that absorbs the heat of the photovoltaic component 100 is converted into heat in the conversion component 300, so that the conversion component 300 generates water vapor for use by the heating component 10.

[0108] In this way, not only can rainwater resources be fully utilized to achieve cooling of 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. The conversion component 300 converts this part of heat into water vapor for use by the heating component 10, which can fully utilize the heat generated by the photovoltaic module 100 and further improve resource utilization.
