Description

[0002] As an important component of clean energy, the application scale and technical level of photovoltaic power generation have been significantly improved. As the core component of the photovoltaic power generation system, the performance and stability of photovoltaic modules are directly related to the power generation efficiency and operating life of the entire system.

[0003] However, in actual applications, the surface temperature of photovoltaic modules rises sharply in areas with strong sunshine and high temperatures, which not only reduces the photoelectric conversion efficiency, but also accelerates the aging of the module materials and shortens the service life. The current method is to install cooling water pipes behind the frame on which the photovoltaic modules are installed, and use the cooling water pipes to continuously cool the photovoltaic modules. However, the cooling water pipes are affected by water vapor and scale for a long time, which not only increases the corrosion rate of the water pipes, but the metal ions produced by corrosion may also cause electrical damage to the photovoltaic modules, further affecting their performance and stability. In addition, the accumulation of scale will form an insulation layer on the inner wall of the water pipe, reducing the cooling effect. At the same time, the cooling effect of the cooling water pipe is limited, and it is difficult to form a cooling effect for a long time. Summary of the invention

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-10 The present invention provides a dustproof photovoltaic module frame, including a frame body 1 and a photovoltaic panel 2. The frame body 1 is composed of four "L"-shaped right-angle frames. The photovoltaic panel 2 is arranged inside the frame body 1. A cooling component 4 is installed inside the frame body 1.

[0027] Among them, the frame body 1 formed by combining four "L"-shaped right-angle frames not only simplifies the installation process, making the assembly of the photovoltaic panel 2 more convenient and quick, but also helps to disperse external impact and wind load, enhances the wind pressure resistance and durability of the entire photovoltaic panel 2, and is suitable for installation and use under various severe weather conditions; each "L"-shaped frame can be disassembled independently, reducing maintenance costs and time; the cooling component 4 integrated inside the frame body 1 can effectively reduce the working temperature of the photovoltaic panel 2. The working efficiency of photovoltaic cells decreases with the increase of temperature. Therefore, through an effective cooling mechanism, the power generation efficiency of the photovoltaic panel 2 in a high temperature environment can be significantly improved to ensure the stability and efficiency of power output.

[0028] In this embodiment, the cooling assembly 4 includes a cooling water pipe assembly 42 installed inside the frame body 1. A bottom plate 43 is provided inside the frame body 1. The cooling water pipe assembly 42 is installed inside the bottom plate 43. A cover plate 41 is installed on the top of the bottom plate 43.

[0029] Among them, through the sealing design between the cover plate 41 and the bottom plate 43, the cooling water pipe is installed inside it, thereby forming an additional barrier, which helps to prevent dust and impurities from entering the photovoltaic panel 2; at the same time, it also reduces the impact of water vapor on the photovoltaic panel 2, so that the polluted gas caused by the long-term use of the water pipe can be sealed, which is also convenient for centralized treatment and reduces environmental pollution.

[0030] In this embodiment, the cooling water pipe assembly 42 includes cooling outer tubes 421 installed side by side inside the base plate 43, a support tube 422 is installed inside the cooling outer tube 421, and a plurality of guide plates 423 are installed on the outer surface of the support tube 422. The cross-section of the guide plate 423 is conical, and a plurality of hydrophobic holes 424 are opened on the surface of the guide plate 423.

[0031] Among them, the guide plate 423 can optimize the distribution of water flow, ensure that the water flow can evenly cover the area that needs cooling, and reduce energy waste; the conical guide plate 423 can guide the water flow to flow in a specific direction, reduce the turbulence and eddy currents of the water flow inside the cooling outer tube 421, thereby improving the flow efficiency and cooling effect of the water flow, and at the same time can enhance the structural strength of the cooling water pipe assembly 42 to a certain extent, and further improve the pressure resistance and durability of the cooling water pipe assembly 42; the hydrophobic holes 424 opened on the surface of the guide plate 423 can accelerate the separation and discharge of the water flow, prevent the water flow from accumulating on the surface of the guide plate 423 or forming a water film, and help to reduce the adhesion and friction of the water flow on the guide plate 423, reduce energy consumption and improve cooling efficiency.

[0032] In some embodiments, a heat-conducting mechanism 425 is disposed inside the support tube 422 . The heat-conducting mechanism 425 includes a heat-conducting rod 4253 installed inside the support tube 422 . One end of the heat-conducting rod 4253 is connected to the outside.

[0033] Among them, the heat flow absorbed by the cooling water inside the cooling outer tube 421 can be centrally discharged through the heat conductive rod 4253, so that the cooling water can be used for a long time; the use of the heat conductive rod 4253 reduces the problems of reduced water flow and decreased cooling effect caused by rust and scale, and the heat conductive rod 4253 is not easy to rust and does not produce scale, thereby ensuring the stability and durability of the cooling effect.

[0034] In some embodiments, a spiral press sheet 4254 is installed on the outer surface of the heat conductive rod 4253, and the interior of the support tube 422 near the spiral press sheet 4254 is filled with refrigerant. The support tube 422 is connected to the generating end of the externally installed evaporator through the steam pipe 4251, and a waterproof and breathable membrane 4252 is installed on the inner wall of the support tube 422 near the steam pipe 4251.

[0035] Among them, the heat conducting rod 4253 is installed inside the support tube 422, and the spiral pressing plate 4254 installed on its outer surface not only increases the contact area with the refrigerant, but also enhances the heat conduction effect through its spiral structure. When the water source inside the cooling water pipe assembly 42 absorbs heat, part of the heat is quickly transferred to the spiral pressing plate 4254 and the refrigerant through the heat conducting rod 4253. After receiving the heat from the heat conducting rod 4253, the refrigerant begins to evaporate. The evaporation process is an endothermic process. Therefore, the refrigerant can absorb and take away a large amount of heat, thereby realizing the cooling of the water source. The evaporated refrigerant is transported to the external evaporator through the steam pipe 4251; the waterproof and breathable membrane 4252 installed on the inner wall of the support tube 422 ensures the smooth transmission of steam, while preventing the entry of moisture or other impurities, thereby ensuring the stable operation of the cooling system.

[0036] In some embodiments, an annular tube 4255 is installed on the outer surface of the support tube 422 , and a plurality of heat absorbing plates 4256 are installed on the inner wall of the guide plate 423 . The heat absorbing plates 4256 are made of galvanized material, and the heat absorbing plates 4256 are connected to the annular tube 4255 .

[0037] Among them, the galvanized material has good thermal conductivity, so the heat absorbing plate 4256 can absorb heat from the water source inside the cooling water pipe more effectively, and is connected to the outside world through the heat conducting rod 4253. The heat absorbing plate 4256 can quickly transfer the absorbed heat, thereby achieving an efficient cooling effect; the surface of the galvanized layer is smooth and not easy to accumulate dirt and impurities, which helps to maintain the cleanliness of the inside of the cooling water pipe assembly 42 and reduce the decrease in cooling efficiency and increase in energy consumption caused by dirt accumulation; the design of the heat absorbing plate 4256 increases the contact area with the cooling water, thereby improving the efficiency of heat exchange.

[0038] In some embodiments, a cleaning assembly 44 is disposed inside the base plate 43, and the cleaning assembly 44 includes a screw 443 rotatably mounted inside the base plate 43, a threaded sleeve 444 is threadedly mounted on the outer surface of the screw 443, a driving mechanism 441 is mounted at the bottom end of the base plate 43, a linkage assembly 442 is installed between the output shaft of the driving mechanism 441 and the screw 443 for transmission, a long plate 445 is slidably mounted at the bottom end of the cover plate 41, and a scraper 446 is rotatably mounted at the bottom end of the long plate 445.

[0039] Among them, by starting the driving mechanism 441, the driving mechanism 441 is equipped with a linkage component 442 for transmission, thereby driving the screw 443 to rotate. Since the long plate 445 will limit the threaded sleeve 444, the screw 443 will drive the threaded sleeve 444 to move, and the threaded sleeve 444 will drive the long plate 445 to move, and the long plate 445 will drive the scraper 446 to move, so that the scraper 446 can clean the outer surface of the cooling water pipe assembly 42. Regular use of the scraper 446 for cleaning can significantly reduce the accumulation of scale and water stains on the surface of the cooling outer pipe 421, thereby maintaining the cleanliness and smoothness of the pipe wall; it helps to improve the heat exchange efficiency of the cooling system, reduce the increase in energy consumption and performance degradation caused by scale, and by reducing the accumulation of scale and water stains, it can avoid the erosion and wear of the inner wall of the cooling outer pipe 421 by these impurities, thereby extending the service life of the cooling water pipe assembly 42.

[0040] In some embodiments, every two scrapers 446 form a cavity, and the cooling outer tube 421 is located inside the cavity. A first spring 447 is installed between every two scrapers 446 , and an arc-shaped sponge pad is installed on the inner wall of the scraper 446 .

[0041] The first spring 447 can realize the squeezing force caused by the friction of the arc-shaped scraper 446 on the cooling outer pipe 421, thereby reducing pipe wear and effectively increasing the service life of the pipe.

[0042] In some embodiments, a limiting mechanism 3 is arranged inside the frame body 1, and the limiting mechanism 3 includes a limiting shell 31 installed inside the frame body 1, and a trapezoidal slide 33 is installed inside the limiting shell 31. Fixed plates 32 are installed at both ends of the slide 33, and a push plate 39 is slidably installed between the two fixed plates 32, and a second spring 34 is installed between the push plate 39 and the slide 33.

[0043] Among them, when the photovoltaic panel 2 is installed, the four sides of the photovoltaic panel 2 can be covered by setting four limit shells 31. At this time, the movement of the push plate 39 will drive the slider 35 to move on the inclined surface of the slide seat 33. The slider 35 drives the support rod 36 to rotate, and the support rod 36 drives the two pressure plates 38 to move towards each other. At this time, the photovoltaic panel 2 can be pressurized by the two pressure plates 38, so that the photovoltaic panel 2 can be stably installed between the four push plates 39. At the same time, the second spring 34 can also form a buffer for the installation of the photovoltaic panel 2, so that when the photovoltaic panel 2 is subjected to external impact and environmental influences, the damage between the photovoltaic panel 2 and the frame body 1 can be minimized.

[0044] In some embodiments, sliders 35 are slidably installed at both ends of the inclined sliding seat 33, a support rod 36 is rotatably installed on the inner wall of the limiting shell 31, one end of the support rod 36 is rotatably connected to the slider 35, and a telescopic component 37 is rotatably installed on the free end of the support rod 36, and a pressure plate 38 is installed at the bottom end of the telescopic component 37.

[0045] Among them, a telescopic component 37 is arranged between the pressure plate 38 and the support rod 36. The telescopic component 37 is composed of a sliding rod and a sliding sleeve, and the sliding rod is slidably installed inside the sliding sleeve, and an auxiliary spring is installed at one end of the sliding rod located inside the sliding sleeve. The telescopic component 37 can increase the buffering pressure used by the pressure plate 38, improve the clamping effect of the pressure plate 38, and reduce the friction damage between the pressure plate 38 and the photovoltaic panel 2.

[0046] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
