For a better understanding of the embodiments of the present invention, the following specific embodiments are disclosed below.

Fig. 1 shows a pultruded composite profile 1 for a photovoltaic module frame, which includes a profile body 11, the profile body 11 includes a cavity 111, a lining member 13 is inserted into the cavity 111 as a profile plug and fixed by an adhesive, meanwhile, the lining member 13 includes a cavity 131, the inner surface of the cavity 131 further includes a raised circular point, the outer surface of the lining member 13 includes a pawl, when the lining member 13 is inserted into the cavity 111 by a positioning tool, if the wall thickness of the cavity 111 has a tolerance, the positioning tool deforms the pawl of the lining member 13 so as to make the relative position of the lining member 13 in the cavity 111 meet the design requirements.

When the photovoltaic module is assembled, the plug connector 2 in the other section of the pultruded composite material profile 1 shown in fig. 2 is inserted into the cavity 131 in the lining 13 in the cavity 111 of the profile 1 shown in fig. 1, and the lining 13 is accurately positioned, so that the plug connector 2 can be smoothly inserted, the splicing seams of the pultruded composite materials 1 at two ends are neat and attractive, and the profile body 11 cannot be cracked due to overlarge stress between the plug connector 2 and the cavity 111. Meanwhile, the inner surface of the cavity 131 of the lining element 13 is also provided with raised dots, when the plug connector 2 is inserted into the cavity 131 of the lining element 13, the raised dots on the inner surface of the cavity 131 deform the barbs on the surface of the plug connector 2, so that the plug connector 2 cannot exit from the cavity 131 to realize accurate, rapid and firm splicing between the two sections of pultruded composite materials.

The barbs of the plug-in connectors 2 shown in fig. 2 are on the inner side of the photovoltaic module frame, and can also be arranged on the outer side or on both sides, and the barbs on the plug-in connectors 2 can also be teeth, protrusions, depressions or notches with the same function, and the like. It can be seen that the lining element 13 not only serves the function of compensating the positioning of the connecting profile 1, but also of reinforcing the ends of the profile 1, since the ends of the pultruded composite profile 1 are the weakest and most prone to cracking, and are subjected to the highest concentrated stresses.

Further, as shown in fig. 9, the pultruded composite profile 1 for photovoltaic module frame in this embodiment further has a profile mounting edge 31, a vertical edge 32 and a cavity 33, wherein the profile mounting edge 31 is connected to the bracket by a bolt 4 and a nut 5 with a diameter of 8mm, an L-shaped gasket or a U-shaped gasket 6 is disposed between the nut 5 and the mounting edge 31, a vertical edge 61 of the L-shaped gasket or the U-shaped gasket 6 is connected to the profile vertical edge 32 by a rivet, a 1mm gap is provided between the bottom of a horizontal edge 62 of the L-shaped gasket or the U-shaped gasket 6 and the upper surface of the profile mounting edge 31, when the photovoltaic module is subjected to reverse wind pressure, the photovoltaic module bracket pulls the pultruded composite profile 1 for frame by the nut 5, so that the profile mounting edge 31 is subjected to cantilever bending force, the bending stress at the root of the profile mounting edge 31 is the largest, and the gap is just one of the lowest-strength portions of the pultruded composite profile 1, if the safety of the photovoltaic module is ensured, the photovoltaic module must be thickened, so that the cost is increased, as before, the L-shaped gasket or the U-shaped gasket 6 is added, the cantilever bending force can be converted into the compressive stress and the shearing stress of the L-shaped gasket or the vertical edge 61 of the U-shaped gasket to the vertical edge 32 of the sectional material through the rivet, the safety coefficient is greatly increased because the strength of the sectional material 1 is enough, meanwhile, the wall thickness of the sectional material 1 is not required to be increased, the cost is prevented from rising, and when the galvanized steel or aluminum alloy reinforcing sheet with the thickness of 0.5-2.5mm and/or the reinforcing ribs perpendicular to the length direction of the sectional material 1 is adopted, the reverse wind pressure resistance of the photovoltaic module can be improved by more than 30%.

Preferably, the lining element 13 is made by plastic extrusion molding, and is welded with the profile body 12 into a whole by a heating mode after being inserted into the profile body 12, so that the bonding step can be eliminated, and the profile body 12 can be reinforced; when the plug connector 2 is inserted into the lining piece 13 in the plugging process, the convex points on the cavity 131 on the lining piece 13 deform to clamp the barbs on the plug connector 2, so that the plug connector 2 is clamped firmly; preferably, the L-shaped gasket or the U-shaped gasket 6 is made of the same resin and positive and negative 45-degree glass fiber biaxial cloth through a pultrusion process, the L-shaped gasket or the U-shaped gasket 6 is welded with the vertical edge and the horizontal edge of the profile in a heating mode for reinforcement, and the reinforcement mode is faster and more reliable.

Preferably, the protruding points may be preformed on the profile body 12, the profile body 12 is softened under heating and then pressed by a protruding tool to form the cavity 111 of the protruding profile plugging portion 12, and then the barbed plug connector 2 is inserted into the cavity 111 at normal temperature, and the protruding points on the cavity 111 and/or the barbs on the plug connector 2 are deformed to achieve firm clamping. When the frame is pieced together to photovoltaic module, heating equipment is for setting up in the hot-blast blowpipe that photovoltaic module pieced together the long limit bight of frame machine, and hot-blast blowpipe aims at the bight heating on long limit and makes it soften, simultaneously, sets up in the pneumatic compact heap of piecing together the long limit bight and presss from both sides tight to long limit bight after plug connector 2 inserts cavity 111, thereby bump messenger long limit bight's cavity 111 produces the bump card jail plug connector 2 on the pneumatic compact heap. Like this, piece together the frame machine to current photovoltaic module and add the pultrusion combined material photovoltaic module that reforms transform a little and just can realize mechanization and piece together the frame. When the optimal scheme of prefabricating the salient points on the profile body 12 is adopted, the frame splicing of the photovoltaic module frame made of the composite material pultrusion profile can be realized without modifying the frame splicing equipment of the photovoltaic module.

Sixth specific example, the difference between the first specific example and the second specific example is that the fibers at the junction of the installation edge 31 and the vertical edge 32 of the profile 1 are reinforced by glass fiber expansion yarns, and the thickness of the profile is 1.5-4mm, so that the photovoltaic module frame made of the profile 1 can bear the bending force generated by the reverse wind pressure even if the photovoltaic module frame is not reinforced by a reinforcing sheet or an L-shaped gasket or a U-shaped gasket 6.
