Description

Technical Field

[0001] The invention relates to the technical field of photovoltaics, in particular to a lightweight photovoltaic component with high waterproofness. Background Art

[0002] In recent years, the society has paid more and more attention to photovoltaic power generation, especially distributed power generation. Rooftop power generation is about to become one of the most critical technologies in photovoltaic power generation. Because the roof has load-bearing requirements, the weight of photovoltaic cell modules has been put forward a higher challenge. There is a huge market demand for lightweight and highly reliable photovoltaic modules.

[0003] For example, the utility model with application number CN202220277944.3 discloses a lightweight photovoltaic module, including: a first module board and a battery cell. The lightweight photovoltaic module pushes the sliding bar to one side, so that the limit block moves horizontally under the linkage of the sliding bar and then disengages from the first module board, so that the slide plate slides downward under the action of gravity and then inserts into the card block, thereby releasing the connection between the battery cell and the first module board, which facilitates the removal and replacement of the battery cell; however, glue is used for bonding and fixing when the photovoltaic module is assembled, and the glue will age after long-term use, causing external water to penetrate through the gap and affect the sealing effect.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a highly waterproof lightweight photovoltaic module is proposed. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a lightweight photovoltaic module with high waterproofness, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a highly waterproof lightweight photovoltaic module, comprising a first photovoltaic module and a first EVA film, a photovoltaic glass is arranged in the middle of the first photovoltaic module, and a encryption plate is installed on the outside of the photovoltaic glass, the first EVA film is arranged on the bottom outer surface of the photovoltaic glass, a battery cell is installed on the bottom outer surface of the first EVA film, and a second EVA film is arranged on the bottom outer surface of the battery cell, a back plate is installed on the bottom of the second EVA film, and limiting holes are provided at the four inner corners of the back plate, a sealing component for gap filling and sealing is installed on the outer surface of the back plate, and the sealing component comprises a bottom frame, a reserved hole, a movable plate, a guide rod and a collecting plate, reserved holes are provided at the four corners of the bottom frame, a guide rod is installed inside the reserved hole, and a movable plate is provided on the top of the guide rod, a collecting plate is installed on the bottom of the guide rod, an adjusting screw is rotatably provided in the middle of the collecting plate, and a middle plate is threadedly installed on the bottom of the adjusting screw.

[0008] Furthermore, first side grooves are provided on both sides of the first photovoltaic component, and the width of the first photovoltaic component is smaller than the width of the first side grooves.

[0009] Furthermore, both upper and lower sides of the first photovoltaic component are provided with assembly components for auxiliary splicing, and two groups of assembly components are provided.

[0010] Furthermore, the assembly component includes a mounting hole, a second side groove and an assembly plate, and a mounting hole is opened inside the first photovoltaic component away from the center of the photovoltaic glass, second side grooves are opened on the upper and lower sides of the first photovoltaic component, and an assembly plate is slidably installed inside the second side groove, and the internal thread of the mounting hole is provided with a positioning stud.

[0011] Furthermore, the second side grooves and the assembly plates are distributed in a one-to-one correspondence, and the assembly plates are snap-connected with the first side grooves.

[0012] Furthermore, the assembly plates are provided in two groups, and the two groups of assembly plates are in an "X"-shaped structure.

[0013] Furthermore, a second photovoltaic component is disposed inside a group of the first side grooves, and the first photovoltaic component and the second photovoltaic component have the same structure.

[0014] Furthermore, a drainage channel is provided at the diagonal inside the first photovoltaic component, and the drainage channel is in an arc-shaped structure. A connecting groove is provided inside the encryption plate, and the shape of the connecting groove is consistent with that of the drainage channel.

[0015] Furthermore, the highly waterproof lightweight photovoltaic assembly also includes the following method of use;

[0016] Step 1: The design of the external mounting frame of the first photovoltaic module of the back plate provides a support frame for the photovoltaic glass, the first EVA film, the battery sheet, the second EVA film and the back plate bonded together by glue, so that a complete photovoltaic module is formed after assembly, and the installation gap between the first photovoltaic module and the photovoltaic glass is preliminarily filled by the encryption plate to achieve proper sealing and hiding of the assembly connection;

[0017] Step 2: When installing the encryption plate and the bottom frame, lithium-based lubricating grease will be stored inside the two, so that it is wrapped around the connection gap between the first photovoltaic module and the photovoltaic glass. Similarly, the lithium-based lubricating grease inside the bottom frame is evenly wrapped between the back plate and the second EVA film. The operator rotates the adjusting screw inside the middle plate clockwise to move the assembly plate connected to the adjusting screw upward, so that the moving plate and the guide rod connected to the assembly plate will move synchronously along the vertical direction of the reserved hole, so that the lithium-based lubricating grease pre-stored in the bottom frame is pressed upward, so that the lithium-based lubricating grease can be filled in the assembly gap between the back plate and the second EVA film through the movement of the moving plate;
