Description

TECHNICAL FIELD

[0001] The present application relates to the field of photovoltaic modules, in particular to a sealing structure of a photovoltaic module frame. BACKGROUND

[0002] In a photovoltaic power generation system, the splicing and maintenance of photovoltaic module frames are crucial. Currently, when splicing photovoltaic module frames, there is often a gap between the two frames. This gap not only affects the overall aesthetics and sealing of the photovoltaic module, but more importantly, it can cause the spliced photovoltaic module frame to tilt and swing. In the long-term use process, this tilt and swing can further affect the stability and power generation efficiency of the photovoltaic module, reducing its service life.

[0003] At the same time, the photovoltaic module frame is exposed to the outdoor environment for a long time, and the surface is easy to accumulate dust, leaves and other debris. These debris can cover the light panel on the surface of the photovoltaic module frame, hindering the normal irradiation of light, thereby reducing the photoelectric conversion efficiency of the photovoltaic module and affecting the power generation capacity.

[0004] In addition, after snow in winter, the surface of the photovoltaic module frame will be covered with snow. The snow that does not melt for a long time will block sunlight, making the photovoltaic module unable to normally receive light to generate electricity, and the weight of the snow may also cause additional pressure on the photovoltaic module frame, damaging the component structure.

[0005] Moreover, when the photovoltaic module is idle for a long time, lacking effective protection measures, the frame is easy to be eroded by the external environment, such as wind, sun, rain, etc., accelerating the aging and damage of the frame, further shortening the service life of the photovoltaic module. Therefore, a sealing structure of a photovoltaic module frame is needed to solve the above problems. SUMMARY

[0006] The purpose of the present application is to provide a sealing structure of a photovoltaic module frame to solve the problems raised in the background.

[0007] To achieve the above purpose, the present application provides the following technical solution: a sealing structure of a photovoltaic module frame, comprising a connecting plate installed at the splicing place of two photovoltaic module frames, the surface of the connecting plate is fixed with a rubber clamp, the rubber clamp is clamped between the two photovoltaic module frames, and the connecting plate is fixed on the top surface of the photovoltaic module frame through a screw rod; The inside of the connecting plate is provided with a reserved cavity, a plurality of air release holes are formed on both sides of the reserved cavity, a gas pump is installed on the top surface of the connecting plate, the gas pump sucks external air and injects it into the reserved cavity and blows it towards the surface of the photovoltaic module frame through the air release holes; One end of the connecting plate is inserted and fixed with a heating pipe, the heating pipe extends into the reserved cavity; The two sides of the connecting plate are provided with receiving grooves, and flexible windproof covers are fixed in the receiving grooves.

[0008] Preferably, the two ends of the connecting plate are fixed with stop blocks, the stop blocks are inserted into the end groove at the joint of the two photovoltaic module frames, and the height of the stop block is equal to the thickness of the photovoltaic module frame.

[0009] Preferably, two reserved grooves are formed in the top surface of the two ends of the connecting plate, and perforations are formed in the bottom surface of the reserved grooves, and the threaded rods are screwed on the surface of the photovoltaic module frame after penetrating through the perforations.

[0010] Preferably, a mounting groove is formed in the top surface of the connecting plate, and an air pump is fixed on the bottom surface of the mounting groove, and the exhaust pipe of the air pump is inserted into the reserved cavity after penetrating through the bottom surface of the mounting groove.

[0011] Preferably, a notch is formed in one end of the connecting plate, and a heating pipe is inserted and fixed on the side wall of the notch.

[0012] Preferably, the flexible windproof cover is inserted into the receiving groove after being folded.

[0013] Preferably, the magic tape includes magic male tapes and magic female tapes, and two magic female tapes are fixed on the surface of the photovoltaic module frame, and the two magic female tapes are symmetrically distributed about the inner ring opening of the photovoltaic module frame, and two magic male tapes are fixed on the surface of the flexible windproof cover, and the two magic male tapes are connected with the two magic female tapes after the flexible windproof cover is unfolded and covers above the photovoltaic module frame.

[0014] Compared with the prior art, the present application has the following advantages: The sealing structure of the photovoltaic module frame disclosed by the present application can effectively fill the gap between the two photovoltaic module frames by fixing the rubber clamping piece on the surface of the connecting plate and clamping it between the two photovoltaic module frames. At the same time, the stop blocks at the two ends of the connecting plate are inserted into the end groove at the joint, and the connecting plate is fixed on the top surface of the photovoltaic module frame by the threaded rods. This design makes the two photovoltaic module frames tightly fixed together, and the rubber clamping piece realizes reliable sealing, avoiding the problem of inclination and swing caused by the gap at the joint, and improving the stability and integrity of the photovoltaic module.

[0015] The connecting plate has a reserved cavity inside, multiple vent holes on both sides, and an air pump installed on the top. Periodically triggering the air pump switch draws in external air, injects it into the reserved cavity, and then blows it onto the surface of the photovoltaic module frame through the vent holes. This blows off surface dust, connection dust, leaves, and other debris, preventing the photovoltaic panels from being covered, ensuring a clean surface for the photovoltaic modules, improving photoelectric conversion efficiency, and reducing power generation loss due to debris accumulation.

[0016] A heating tube extending into a pre-reserved cavity is inserted and fixed to one end of the connecting plate. When snow falls, the heating tube switch is triggered, and the temperature generated can melt the snow around the connecting plate. At the same time, in conjunction with an air pump, hot air from inside the flexible windshield can be blown towards the frame of the photovoltaic module, accelerating the melting of surface snow, reducing the impact of snow on photovoltaic module power generation, and reducing the risk of damage to the module structure due to the weight of snow.

[0017] The connecting plate has storage slots on both sides, inside which flexible windshields are fixed. When the photovoltaic modules are not in use for a long period of time, the flexible windshields can be pulled out from the storage slots and unfolded. They are then attached to the frame of the photovoltaic modules using Velcro straps, providing effective protection against external environmental corrosion and extending the lifespan of the photovoltaic modules. After use, the flexible windshields can be folded back into the storage slots for convenient and practical storage. Attached Figure Description
