Technical Field

[0001] The utility model relates to the technical field of photovoltaic component packaging, in particular to a photovoltaic component packaging structure resistant to salt spray. Background Art

[0002] Photovoltaic modules are the core components of photovoltaic power generation applications. Currently, the front and back panels of commonly used photovoltaic modules are made of tempered glass. In the existing photovoltaic module assembly process, aluminum frames are used to encapsulate the bare panel components of the photovoltaic module, which plays a role in protecting the bare panel components of the photovoltaic module and makes the photovoltaic module have good pressure-bearing capacity.

[0003] According to the Chinese patent with publication number: CN219873550U, a photovoltaic packaging component includes a photovoltaic laminate and a skeleton packaging component; the photovoltaic laminate includes a front packaging part, a battery string layer and a back packaging part which are laminated and composited into one; the skeleton packaging component includes at least a skeleton core layer and a surface layer which are composited into one; the photovoltaic laminate and the skeleton packaging component are packaged and composited into one by a cold bonding process to obtain a photovoltaic packaging component.

[0004] In the above scheme, a skeleton package is used instead of a metal frame as the lining structure of the photovoltaic module, which still has the following disadvantages: the photovoltaic module is inside the skeleton package, but the position of the photovoltaic module is not limited and fixed. When the angle of the photovoltaic module is adjusted, it may swing and the firmness of the photovoltaic module is low. Utility Model Content

[0005] The utility model aims to provide a salt-fog resistant photovoltaic module packaging structure to solve the problem that the photovoltaic module may sway when the angle is adjusted because the position of the photovoltaic module is not limited and fixed, and the photovoltaic module has low firmness.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a salt-spray resistant photovoltaic module packaging structure, comprising a base plate, a frame is detachably provided on the top surface of the base plate, a packaging plate is fixed on the top surface of the frame, two extrusion plates are provided inside the frame, a flip bar is flipped on the top surface of the extrusion plate, two hinges are provided on the top surface of the extrusion plate, the extrusion plate and the flip bar are rotatably arranged by the hinges, a fixing bar is fixed on one side of the extrusion plate, a limiting sleeve is fixed on the top surface of the flip bar, a limiting pin is slidably inserted on the fixing bar, one end of the limiting pin passes through the fixing bar and is slidably inserted with the limiting sleeve.

[0007] Preferably, two sliding holes are respectively provided on both sides of the frame, a sliding rod is slidably inserted inside the sliding hole, one end of the sliding rod is fixed to one side of the extrusion plate, a spring is surrounded by the surface of the sliding rod, one end of the spring is fixed to one side of the extrusion plate, and the other end of the spring is fixed to one side of the inner side of the frame.

[0008] Preferably, a storage groove is provided on the top surface of the bottom plate, a sealing frame is fixed to the bottom surface of the frame, and the storage groove and the sealing frame are interference fit.

[0009] Preferably, a fixing plate is fixed on both sides of the frame, a through hole is provided on one side of the fixing plate, a fixing bolt is rotatably inserted inside the through hole, and two thread grooves are provided on both sides of the bottom plate, one end of the fixing bolt passes through the through hole and is threadedly connected to the thread groove.

[0010] Preferably, semi-arc blocks are fixed on both sides of the frame, and splicing blocks are fixed on both sides of the bottom plate.

[0011] Preferably, drainage grooves are respectively provided on both sides of the frame.

[0012] Compared with the prior art, a salt-fog resistant photovoltaic module packaging structure using the above technical solution has the following beneficial effects:

[0013] 1. The staff will install the photovoltaic module inside the frame. Since the packaging plate on the top of the frame is made of tempered glass, the salt spray-resistant coating is sprayed on the surface of the bottom plate and the frame, and the two sides of the photovoltaic module are fitted with one side of the extrusion plate. The photovoltaic module is clamped and fixed inside the frame using two extrusion plates. When the two extrusion plates are fitted on both sides of the photovoltaic module, the flip bar and the extrusion plate are perpendicular to each other. Then the staff will pass the limit pin through the fixing bar and enter the inside of the limit sleeve to fix the flip bar in the current state and intercept it on the top surface of the photovoltaic module to prevent the photovoltaic module from shaking inside the frame, thereby increasing the firmness of the photovoltaic module inside the frame.

[0014] 2. When the photovoltaic modules inside the frame are damaged, the staff will first unscrew the fixing bolts out of the threaded grooves, and then move the frame upwards to facilitate the staff to replace the damaged photovoltaic modules. When the bottom plate and the frame are assembled and installed together, the sealing frame will enter the storage slot and have an interference fit with it, thereby increasing the sealing between the bottom plate and the frame.

[0015] 3. When the bottom plate and the frame are assembled together, the semi-arc blocks and the splicing blocks will be driven to be assembled together, so that the angle of the photovoltaic module can be adjusted with the semi-arc blocks and the splicing blocks as the center when the photovoltaic module is in use. When water droplets accumulate inside the frame due to condensation of water vapor, the accumulated water can be discharged through the drainage groove as the frame tilts, which is convenient for cleaning the accumulated water inside the frame.
