Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic technology, specifically to solar photovoltaic modules. Background Technology

[0002] Solar photovoltaic modules are typically installed outdoors and can convert solar energy into direct current (DC) electricity.

[0003] Existing solar photovoltaic modules, such as the novel solar photovoltaic module disclosed in Chinese patent CN219999285U, although they achieve functions such as convenient maintenance and replacement of solar panels, are usually installed on rooftops. In winter, a thick layer of ice or snow easily accumulates on the surface of the solar panels and is difficult to melt for a long time. This structure does not achieve the function of quickly removing ice or snow from the surface of the solar panels. The accumulation of ice or snow on the surface of the solar panels for a long time will affect the solar panels' reception of sunlight, thereby affecting the power generation efficiency of the photovoltaic module. Utility Model Content

[0004] In view of the shortcomings of the prior art mentioned in the background section, this utility model provides a solar photovoltaic module.

[0005] This utility model overcomes the above technical problems by adopting the following technical solution:

[0006] A solar photovoltaic module includes a base and a solar panel. A fan is fixedly installed on one side of the base. One end of the fan is connected to a connecting pipe. The end of the connecting pipe is connected to a movable air duct. An air outlet is provided on the movable air duct. A heating wire is installed on the outer side of the movable air duct near the air outlet.

[0007] A drive component that acts on the mobile air duct is provided between the base and the mobile air duct.

[0008] As a further embodiment of this utility model: the driving component includes two sets of screws rotatably connected to both sides of the solar panel, and a screw sleeve sleeved on the screws and fixedly connected to both sides of the movable air duct;

[0009] A synchronous power assembly acting on the screws is provided between the base and the two sets of screws.

[0010] As a further embodiment of this utility model: the synchronous power assembly includes a servo motor mounted on one side of the base, a first gear sleeved on one end of the output shaft of the servo motor, a second gear sleeved on the ends of the two sets of screws, and a belt disposed between the first gear and the second gear.

[0011] As a further improvement of this utility model, the air outlets are arranged in multiple groups at equal intervals on the movable air duct.

[0012] As a further improvement of this utility model, the connecting pipe is a telescopic corrugated pipe.

[0013] As a further improvement of this utility model: a lightning rod is installed on the base, and a lightning-attracting flat iron is connected to the bottom end of the lightning rod.

[0014] With the above structure, this utility model has the following advantages compared with the prior art: Through the combined action of connecting pipes, moving air ducts, air outlets, heating wires, fans, and drive components, the moving air duct can move horizontally back and forth along the solar panel while generating hot air that is evenly blown onto the surface of the solar panel. The ice or snow accumulated on the solar panel can melt faster under the baking effect of the hot air, effectively removing the ice or snow from the surface of the solar panel, ensuring that the solar panel receives sunlight without being affected by ice or snow, thereby ensuring the power generation efficiency of the photovoltaic module.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figures 1-3 In this embodiment of the utility model, the solar photovoltaic module includes a base 1 and a solar panel 2. A fan 15 is fixedly installed on one side of the base 1. One end of the fan 15 is connected to a connecting pipe 3. The end of the connecting pipe 3 is connected to a movable air duct 4. An air outlet 5 is provided on the movable air duct 4. An electric heating wire 6 is installed on the outer side of the movable air duct 4 near the air outlet 5.

[0021] A drive component that acts on the mobile air duct 4 is provided between the base 1 and the mobile air duct 4.

[0022] The air outlet 5 on the mobile air duct 4 faces the surface of the solar panel 2. After the fan 15 is started, the airflow generated by the fan 15 will be blown into the mobile air duct 4 through the connecting pipe 3. The airflow in the mobile air duct 4 will be blown out through the air outlet 5. During this process, the heating wire 6 can be started to generate heat. When the airflow blown out of the air outlet 5 passes through the heating wire 6, it will form hot air that blows towards the solar panel 2. The driving component can drive the mobile air duct 4 to move horizontally back and forth along the surface of the solar panel 2. While the mobile air duct 4 moves horizontally back and forth along the solar panel 2, it can blow hot air evenly onto the surface of the solar panel 2. The ice or snow accumulated on the solar panel 2 can melt faster under the baking effect of the hot air, effectively removing the ice or snow on the surface of the solar panel 2. This ensures that the solar panel 2 is not affected by ice or snow while receiving sunlight, thereby ensuring the power generation efficiency of the photovoltaic module.

[0023] In one embodiment of the present invention, the driving assembly includes two sets of screws 7 rotatably connected to both sides of the solar panel 2, and a screw sleeve 8 sleeved on the screws 7 and fixedly connected to both sides of the movable air duct 4;

[0024] A synchronous power assembly acting on the screws 7 is provided between the base 1 and the two sets of screws 7;

[0025] The synchronous power assembly can synchronously drive the two sets of screws 7 to rotate in both directions. Due to the meshing relationship between the screws 7 and the sleeves 8, the screws 7 will drive the sleeves 8 on them to reciprocate along the surface of the screws 7 during the forward and reverse rotation. During this process, the moving air duct 4 will move horizontally along the surface of the solar panel 2 under the drive of the sleeves 8 at both ends.

[0026] In another embodiment of the present invention, the synchronous power assembly includes a servo motor 9 mounted on one side of the base 1, a first gear 10 sleeved on one end of the output shaft of the servo motor 9, a second gear 11 sleeved on the ends of the two sets of screws 7, and a belt 12 disposed between the first gear 10 and the second gear 11.

[0027] By starting the servo motor 9, the output shaft of the servo motor 9 can drive the first gear 10 to rotate in both directions. At this time, the first gear 10 will drive the second gear 11 at the ends of the two sets of screws 7 to rotate in both directions through the transmission action of the belt 12, thereby enabling the two sets of screws 7 to rotate in both directions synchronously under the drive of the second gear 11.

[0028] In another embodiment of this utility model, the air outlets 5 are distributed in multiple groups at equal intervals on the movable air duct 4;

[0029] Multiple sets of equidistant air outlets 5 can make the airflow in the mobile air duct 4 blow out from one side of the mobile air duct 4 more evenly. When the mobile air duct 4 moves horizontally back and forth along the surface of the solar panel 2, it ensures that the hot air blown out by the mobile air duct 4 can evenly cover all positions on the surface of the solar panel 2.

[0030] In another embodiment of this utility model, the connecting pipe 3 is a telescopic corrugated pipe;

[0031] The connecting pipe 3, made of telescopic corrugated pipe, can extend or retract horizontally as the mobile air duct 4 moves horizontally back and forth, ensuring that the airflow generated by the solar panel 2 can be smoothly delivered into the mobile air duct 4 while the mobile air duct 4 is moving.

[0032] In another embodiment of the present invention, a lightning rod 13 is installed on the base 1, and a lightning-attracting flat iron 14 is connected to the bottom end of the lightning rod 13.

[0033] The lightning rod 13 is located near the solar panel 2 and is higher than the solar panel 2. When lightning strikes the vicinity of the solar panel 2, the lightning rod 13 can guide the lightning to it. The lightning-attracting flat iron 14 is electrically connected to the lightning protection of the roof. The current will be conducted along the lightning rod 13 and guided to the lightning protection strip on the roof through the lightning-attracting flat iron 14, thereby effectively preventing the solar panel 2 from being damaged by lightning.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
