[0002] A photovoltaic module refers to a facility that converts solar energy into direct current electricity by using the photovoltaic effect of photovoltaic semiconductor materials. The core of a photovoltaic facility is a solar panel. The semiconductor materials used for power generation mainly include: monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, etc.

[0003] At present, in order to achieve rapid assembly and connection of photovoltaic modules, connection structures are provided on the plate bodies to realize mutual combination. For example, a kind of photovoltaic tile disclosed in Chinese Patent Publication No. "CN208445516U" includes: a photovoltaic module; a tile plate located on the backlight side of the photovoltaic module for fixing the photovoltaic module; the tile plate includes a first tile plate and a second tile plate located above the first tile plate; wherein, in a first direction, the first tile plate has a first protruding portion, and the second tile plate has a second protruding portion.

[0004] Since most of the existing connection structures are designed with relatively complex structures and it is difficult to achieve rapid and accurate positioning during assembly, the efficiency in the actual assembly process is low. In order to further optimize the assembly efficiency and accuracy of photovoltaic modules, a splicing structure for photovoltaic power generation is proposed. Summary of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0026] As Figures 1 to 8 shown, it shows a splicing structure for photovoltaic power generation provided by an embodiment of the present application, including a photovoltaic module body 1 and a splicing structure. The splicing structure includes a fixing frame and a fixing member. The photovoltaic module body 1 is fixed in the fixing frame by an embedding method. A positioning groove 23 is provided on the fixing frame, and a fixing hole 24 is provided on the positioning groove 23. Four elastic buckles are provided on the fixing member. By rotating the fixing member, the elastic buckles are buckled into the fixing holes 24 of the positioning groove 23 to fix the four fixing frames to each other. In this embodiment, the minimum constituent unit is four fixing frames, and then they can be stacked according to the actual required quantity. It is only necessary to set corresponding positioning grooves 23 and positioning holes at adjacent positions of the fixing frames.

[0027] In some embodiments, the fixing frame includes a U-shaped frame 22, a cross bar, and a fixing bolt 25. First connection holes 221 are provided at both ends of the cross bar, and second connection holes 211 corresponding to the first connection holes 221 are provided on the two end faces of the U-shaped frame 22. The fixing bolt 25 is threadedly connected to the first connection hole 221 and the second connection hole 211 to fix the U-shaped frame 22 and the cross bar. After the installer places the photovoltaic module body 1 into the U-shaped frame, aligns the first connection hole 221 and the second connection hole 211, and inserts the fixing bolt 25 through, and tightens the fixing bolt 25 to achieve the purpose of fixing the photovoltaic module body 1.

[0028] In some embodiments, symmetric first limiting tracks 222 are provided on both sides inside the U-shaped frame 22, and a second limiting track 212 is provided on the inner side of the one-piece frame. Limiting protrusions 11 are provided on three sides of the photovoltaic module body 1, and the limiting protrusions 11 are respectively inserted into the first limiting track 222 and the second limiting track 212 to fix the photovoltaic module body 1. The installer first places the photovoltaic module body 1 into the first limiting track 222 of the U-shaped frame 22 to fix the upper and lower sides, and then aligns the second limiting track 212 on the one-piece frame with one end of the limiting protrusion 11 on the side and inserts it until the first connection hole 221 and the second connection hole 211 are aligned.

[0029] In this embodiment, the positioning groove 23 is provided at the bending part of the U-shaped frame 22, and a through groove 231 is connected to one side of the positioning groove 23, and four adjacent through grooves 231 are connected to allow the connecting screw 32 to pass through. The fixing member further includes a knob 31, a connecting screw 32 and a housing 33. The lower end of the knob 31 is fixedly connected to the connecting screw 32. The connecting screw 32 passes through the through groove 231 and is connected to the housing 33. The lower end of the connecting screw 32 is fixedly connected to four elastic buckles. Rotating the knob 31 causes the connecting screw 32 to drive the four elastic buckles to rotate, so that each elastic buckle can be buckled into the fixing hole 24.

[0030] In some embodiments, the elastic buckle includes a connecting rod 34, a spring 35 and a fastener 36. The connecting rod 34 is fixed to the lower end of the connecting screw 32. The fastener 36 is fixed to the connecting rod 34 through the spring 35. The spring 35 has a certain potential energy in the initial state, so that the fastener 36 and the connection are kept in a vertical state. An arc surface 241 and a fixing surface 242 are provided in the fixing hole 24. The arc surface 241 is matched and fixed with the fastener 36. When the connecting rod 34 rotates to drive the fastener 36 to the arc surface 241, the fastener 36 abuts against the arc surface 241 and unfolds forward until the fastener 36 is buckled with the arc surface 241 to fix the whole structure.

[0031] During use, first install the four photovoltaic module bodies 1 into the fixing frame along the first limiting track 222 and the second limiting track 212 respectively, and tighten them with the fixing bolts 25. Then place the fasteners 36 of the elastic buckles into the positioning grooves 23 of the four fixing frames, align them with the fixing holes 24 and combine them. At this time, the elastic buckles are in the initial state. Then rotate the knob 31 by hand to buckle each fastener 36 to reach the fixed state, so as to achieve the purpose of fixedly connecting the four adjacent fixing frames. When the structure needs to be removed, pop out the fasteners 36 from the fixing holes 24 behind the fixing frame to separate the four adjacent fixing frames, and the removal purpose can be achieved. The whole removal process is very simple and fast.

[0032] The utility model enables the photovoltaic module body 1 to be quickly positioned and fixed in the fixing frame through the arrangement of the first limiting track 222 and the second limiting track 212 on the fixing frame, improving the installation efficiency; through the arrangement of the fixing piece and the elastic buckle, four adjacent fixing frames are fixed to each other, making the whole structure have good stability and installation strength.
