[0041] The structure of the present invention is further explained below with a specific embodiment:

[0042] like Figure 3As shown, the point-type fixed terminal 1 is in the shape of an inverted chair as a whole. The point-type fixed terminal 1 includes a base 11, a base screw hole 12, a docking claw 13, a docking claw side screw hole 14, and a docking claw upper screw hole 15. The point-type fixed terminal 1 is made of an integral cast of aluminum alloy. The base 11 is square, and four base screw holes 12 are symmetrically arranged on both sides of the central axis. The base screw holes 12 are used to fix the point-type fixed terminal 1 on the purlin 7 of the factory building below, and are connected in the middle with bolts. The base 11 extends four docking claws 13 outward, and the cross-section of the docking claws 13 is square. The docking claws 13 are used as the main supporting mechanism for the BIPV photovoltaic panel fixing structure. A docking claw side screw hole 14 is provided on the inner side of the docking claw 13 near the lower side of the horizontal central axis of the docking claw 13, which is used to fix the main water tank 3. A docking claw upper screw hole 15 is provided on the top surface of the docking claw 13, which is used to fix the component installation purlin 2.

[0043] like Figure 1 As shown, the point-type fixed terminal 1 is fixed to the purlin 7 of the factory building by bolts. The main water trough 3 is an inverted trapezoidal trough structure, which is the main flow channel for rainwater. The main water trough 3 is arranged in the hollow position inside the point-type fixed terminal 1, and the left and right oblique sides of the inverted trapezoid of the main water trough 3 are fixed to the screw holes 14 on the docking claw side of the point-type fixed terminal 1 by bolts. The point-type fixed terminal 1 provides a clamping and fixing effect for the main water trough 3. The adjacent main water troughs 3 are connected by bolts. The component installation purlin 2 is fixed to the screw holes 15 on the docking claw of the point-type fixed terminal 1 by bolts.

[0044] like Figure 2 As shown, the secondary water guide groove 4 is an inverted trapezoidal groove structure, overlapped between adjacent main water guide grooves 3, and the secondary water guide groove 4 is fixed on the main water guide groove 3 through the secondary water guide groove clamp 6. There is a certain gap between the photovoltaic components 8, and the gap is pressed on the component installation purlin 2 through the photovoltaic clamp 5. The photovoltaic clamp 5 is a rectangular flat aluminum alloy block with a bolt hole in the middle. The photovoltaic clamp 5 is connected to the component installation purlin 2 through the bolt hole.

[0045] like Figure 5 As shown, the secondary water channel fixture 6 is a multi-faceted three-dimensional structure. The first inclined surface 61 is an inclined surface with the same trapezoidal slope as the secondary water channel 4. The first inclined surface 61 has two screw holes for fixing with the secondary water channel 4 by bolts. The second inclined surface 63 is an inclined surface with the same trapezoidal slope as the primary water channel 3.

[0047] When it rains, rainwater leaking from the short sides of the photovoltaic module 8 falls directly into the main water channel 3 and flows away, while rainwater leaking from the long sides of the photovoltaic module 8 first falls into the secondary water channel 4. The secondary water channel 4 guides the rainwater to both ends of the secondary water channel 4 and falls into the main water channel 3 and flows away.

[0048] It should be noted that the above is only one of the embodiments of the present invention, and equivalent changes made to the system described in the present invention are all included in the protection scope of the present invention.
