[0037] In order to enable those skilled in the art to better understand the technical solutions in this application, the following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0040] The Qinghai-Tibet Plateau is rich in sunlight resources, with high annual utilization hours, and has great potential for photovoltaic project construction. However, due to its high altitude, low latitude, high mountains and dangerous rapids, and rugged terrain, there is a large area of plateau permafrost. Specifically, permafrost refers to a special rock and soil body with a soil temperature below 0°C and containing ice, which can be divided into short-term permafrost, seasonal permafrost, and permafrost.
[0041] It is extremely difficult to build photovoltaic projects on the Qinghai-Tibet Plateau. In addition to the harsh climate and fragile environment, the most difficult technical problem to solve is that the permafrost on the plateau is easily thawed by heat, which can lead to instability in the photovoltaic support pile foundation.
[0042] Specifically, in the cold winter, as the temperature drops, the water contained in the frozen soil increases in volume during the process of condensing into ice, causing the frozen soil to expand. The pile foundation and photovoltaic bracket built on the frozen soil will be lifted up by the expanded frozen soil. In the summer, when the ambient temperature rises, the frozen soil melts and shrinks in volume, causing the pile foundation and photovoltaic bracket to sink again.
[0043] Under the repeated freezing and thawing of frozen soil, pile foundations will experience problems such as slurry, mud, settlement and deformation, causing the photovoltaic bracket to twist and deform, and become ups and downs. Therefore, if the problems of frozen soil thawing, settlement and expansion deformation cannot be solved when building photovoltaic power stations in plateau permafrost areas, it will cause serious damage to the pile foundation and pose a serious threat to the photovoltaic panels.
[0044] In order to solve the problem that the permafrost on the plateau is easily unstable due to the thawing of the permafrost, the present application provides a solar refrigeration device. The solution provided by the embodiment of the present application will be described in detail below in conjunction with the drawings of the specification.
[0045] Figure 1 It is a schematic diagram of the overall structure of a solar refrigeration device provided in one embodiment of the present application; Figure 2 yes Figure 1 Schematic diagram of the structure of the triangular tube 110 of the solar module 100.
[0046] Reference Figure 1 and Figure 2 As shown, an embodiment of the present application provides a solar refrigeration device, including: a solar module 100, a pipeline 200, a condenser 300, a liquid storage tank 400 and an evaporator 500.
[0047] Among them, the solar energy component 100 includes a triangular tube 110, in which activated carbon 112 is arranged, the triangular tube 110 is connected to the condenser 300 through the pipeline 200, the condenser 300 is connected to the liquid storage tank 400 through the pipeline 200, the liquid storage tank 400 is connected to the evaporator 500 through the pipeline 200, and the evaporator 500 is connected to the triangular tube 110 through the pipeline 200.
[0048] The triangular tube 110 , the pipeline 200 , the condenser 300 , the liquid storage tank 400 and the evaporator 500 form a circulation loop, in which a refrigerant is arranged. The evaporator 500 is arranged around the pile foundation of the photovoltaic support 800 .
[0049] The activated carbon 112 is used to absorb the gaseous refrigerant, the condenser 300 is used to condense the gaseous refrigerant into a liquid refrigerant, the liquid storage tank 400 is used to store the liquid refrigerant, and the evaporator 500 is used to convert the liquid refrigerant into a gaseous refrigerant. It is understood that after the liquid refrigerant flowing from the liquid storage tank 400 into the evaporator 500 is converted into a gaseous refrigerant in the evaporator 500, it will absorb the heat in the frozen soil around the evaporator 500, thereby making the frozen soil stable and avoiding the occurrence of the problem of the pile movement of the photovoltaic bracket 800 due to the thawing of the frozen soil.
[0050] In addition, the gaseous refrigerant flowing out of the evaporator 500 will be absorbed by the activated carbon 112 in the triangular tube 110. After being exposed to the sun for a long time, the temperature of the triangular tube 110 rises, and the activated carbon 112 will release the gaseous refrigerant again. Then the gaseous refrigerant is condensed by the condenser 300 and becomes liquid refrigerant and flows back to the liquid storage tank 400, completing the refrigerant cycle. It can be understood that during the refrigerant circulation process, the heat of the frozen soil around the evaporator 500 can be reduced to prevent it from thawing and softening, which is conducive to maintaining the stability of the foundation pile of the photovoltaic bracket 800.
[0051] Exemplarily, the refrigerant may be methanol.
[0052] Continue to refer to Figure 2 As shown, the triangular tube 110 includes a triangular shell 111, a partition 113 and a metal sieve tube 115. The metal sieve tube 115 is located in the triangular shell 111, and the extension direction of the metal sieve tube 115 is the same as the extension direction of the triangular shell 111. One end of the partition 113 is connected to the triangular shell 111, and the other end is connected to the metal sieve tube 115. The triangular shell 111, the partition 113 and the metal sieve tube 115 enclose a containing space, and the activated carbon 112 is arranged in the containing space.
[0053] The metal sieve tube 115 is provided with a through hole 114, and the through hole 114 is used to connect the inside of the metal sieve tube 115 with the containing space. It is understood that during the day, sunlight directly shines on the triangular tube 110, causing the temperature inside the triangular tube 110 to rise. When the temperature inside the tube reaches the decomposition temperature of methanol, gaseous methanol is desorbed from the activated carbon 112, passes through the metal sieve tube 115, and gathers inside the metal sieve tube 115.
[0054] In some other examples, the partition 113 is a metal heat conductor, and the heat of the outer wall of the triangular tube 110 can be quickly transferred to the inside of the triangular tube 110 through the metal heat conductor, so that the inside of the triangular tube 110 is quickly heated up.
[0055] In some other examples, the metal sieve tube 115 is evenly distributed with through holes 114 , so as to facilitate the gaseous methanol in the accommodation space of the triangular tube 110 to flow to the interior of the metal sieve tube 115 in a timely manner.
[0056] Figure 3 yes Figure 1 A first structural schematic diagram of the solar module 100; Figure 4 yes Figure 1 A second structural schematic diagram of the solar module 100: Figure 5 yes Figure 1 A cross-sectional view of a solar module 100; Figure 6 yes Figure 5 A cross-sectional view of the solar module 100 along AA.
[0057] Reference Figures 3 to 6 As shown, in some examples, the solar module 100 includes a plurality of triangular tubes 110, and the plurality of triangular tubes 110 are evenly distributed along the width direction of the solar module 100. It should be noted that the width direction of the solar module 100 can refer to Figure 3 It is understood that the plurality of triangular tubes 110 can absorb more methanol gas, which can ensure that more methanol circulates in the circulation loop, which is beneficial to lowering the temperature of the dynamic frozen soil and keeping it in a stable state.
[0058] Continue to refer to Figure 4 As shown, in some embodiments, the solar refrigeration device further includes a collecting pipe 1100, and the ends of each triangular tube 110 are connected to the collecting pipe 1100. One end of the collecting pipe 1100 is connected to the condenser 300 through the pipeline 200, and the other end is connected to the evaporator 500 through the pipeline 200. It can be understood that in these embodiments, multiple triangular tubes 110 in the solar module 100 can be connected to the condenser 300 and the evaporator 500 through one collecting pipe 1100. In other embodiments, each triangular tube 110 can also be connected to the condenser and the evaporator 500 respectively by using the pipeline 200. Exemplarily, a shell 1000 is provided above the collecting pipe 1100 to protect the collecting pipe 1100 and extend its service life.
[0059] Continue to refer to Figure 6 As shown, the solar module 100 also includes a box 130 and a transparent cover 120. The box 130 includes a bottom plate and a side wall. The bottom plate and the side wall enclose a placement space. A plurality of triangular tubes 110 are sequentially arranged in the placement space. The transparent cover 120 is arranged on the side wall and closes the placement space. It can be understood that the triangular tube 110 is arranged in a closed placement space, which is conducive to the temperature increase and heat preservation inside the triangular tube 110. In addition, illustratively, the material of the transparent cover 120 can be PVC material or glass. The specific material is not limited as long as it can pass sunlight.
[0060] Continue to refer to Figure 1As shown, a one-way vacuum valve 600 and a pressure gauge 700 are provided on the pipeline 200 between the triangular tube 110 and the condenser 300. The one-way vacuum valve 600 can ensure that the gaseous methanol in the triangular tube 110 can flow to the condenser 300 in one direction for condensation; the pressure gauge 700 is used to display the pressure of the gaseous methanol in the pipeline 200.
[0061] In addition, a vacuum valve 1200 is provided on the pipeline 200 between the liquid storage tank 400 and the evaporator 500, and the vacuum valve 1200 is used to control the on-off of the pipeline 200 between the liquid storage tank 400 and the evaporator. When the vacuum valve 1200 is opened, the liquid methanol in the liquid storage tank 400 can flow into the evaporator 500.
[0062] In some other examples, a throttle valve 1300 is provided on the pipeline 200 between the evaporator 500 and the triangular tube 110. When the throttle valve 1300 is opened, due to the sudden drop in pressure, the liquid methanol in the evaporator 500 begins to absorb the surrounding heat and then transforms into gaseous methanol again and re-enters the triangular tube 110 through the pipeline.
[0063] Continue to refer to Figure 1 As shown, in some examples, in order to improve the refrigeration efficiency, the solar refrigeration device includes a plurality of solar modules 100, wherein the plurality of solar modules 100 are respectively connected to the condenser 300, and the plurality of solar modules 100 are respectively connected to the evaporator 500. Exemplarily, the plurality of solar modules 100 are arranged side by side.
[0064] Continue to refer to Figure 1 As shown, the solar refrigeration device further includes a base 900 and a bracket 800, the base 900 is fixed on the ground, the bracket 800 is fixed on the base 900, and the solar module 100 is tiltedly arranged on the bracket 800. The tilt angle of the solar module 100 can be adaptively adjusted according to the direct angle of the sun in different regions to ensure that the sunlight can directly hit the solar module 100, so that the triangular tube 110 in the solar module 100 can heat up faster.
[0065] Figure 7 yes Figure 1 A schematic structural diagram of the middle condenser 300; Figure 8 yes Figure 1 Schematic diagram of the structure of the evaporator 500.
[0066] Reference Figure 7As shown, the condenser 300 has a condenser inlet 310 and a condenser outlet 320. Gaseous methanol enters the condenser 300 from the condenser inlet 310, and the gaseous methanol is condensed into liquid methanol in the condenser 300, and the liquid methanol can flow out from the condenser outlet 320. Exemplarily, the condenser 300 can adopt a fin-tube heat exchanger to condense the internal gaseous methanol by means of heat conduction of external cold air, convection heat exchange, etc.
[0067] Reference Figure 8 As shown, the evaporator 500 is a tubular wound evaporator 500, and the photovoltaic support 800 pile foundation is arranged inside the tubular wound evaporator 500, so that the tubular wound evaporator 500 can easily cool the frozen soil around the photovoltaic support 800 pile foundation.
[0068] In addition, specifically, the evaporator 500 has an evaporator inlet 510 and an evaporator inlet 520. Liquid methanol enters the evaporator 500 from the evaporator inlet 510, and the liquid methanol is converted into gaseous methanol in the evaporator 500. After the liquid methanol is converted into gaseous methanol, it absorbs heat in the frozen soil, and finally the gaseous methanol flows out from the evaporator inlet 520.
[0069] During the day, the staff closes the throttle valve 1300, and the internal temperature of the triangular tube 110 increases after absorbing solar energy, and the gaseous methanol is decomposed from the activated carbon 112. When the pressure of the gaseous methanol in the pipeline 200 reaches the methanol condensation pressure, the one-way vacuum valve 1200 is opened, and the gaseous methanol flows to the condenser 300, and then the gaseous methanol is converted into liquid methanol in the condenser 300.
[0070] Under the sun's irradiation, the triangular tube 110 continuously absorbs solar energy, and the gaseous methanol is continuously heated and desorbed, and the desorbed gaseous methanol is condensed into liquid methanol in the condenser 300, and then the liquid methanol is stored in the liquid storage tank 400. When the methanol in the activated carbon 112 is completely desorbed, the vacuum valve 1200 is opened, and the liquid in the liquid storage tank 400 flows into the evaporator 500.
[0071] In the evening, when there is no direct sunlight on the solar module 100, the temperature of the solar module 100 drops rapidly as the ambient temperature decreases, and the pressure in the triangular tube 110 also gradually decreases. When the temperature drops to the evaporation pressure, the throttle valve 1300 is opened. Due to the sudden drop in pressure, the liquid methanol in the evaporator 500 begins to absorb the surrounding heat and then converts into gaseous methanol again, and the activated carbon 112 adsorbs the gaseous methanol. In the process of liquid methanol turning into gaseous methanol in the evaporator 500, the temperature of the frozen soil around the evaporator 500 can be reduced and its state can be kept stable, thereby ensuring the stability of the photovoltaic support pile foundation.
[0072] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application. Any modifications, equivalent substitutions, improvements, etc. made on the basis of the technical solutions of the embodiments of the present application should be included in the protection scope of the embodiments of the present application.
