In this embodiment, as shown in fig. 4, the pressing hook 5 has a C shape, the pressing hook 5 has a pressing portion 51 at an upper end thereof and a supporting portion 52 at a lower end thereof, and the supporting portion 52 is provided with an adjusting mechanism; the adjusting mechanism abuts against the bottom of the longitudinal drain groove 2, a gap is formed between the upper surface of the longitudinal drain groove 2 and the pressing portion 51, the gap is used for accommodating the second folded edge 022 of the photovoltaic panel 02, and the size of the gap is adjusted by adjusting the adjusting mechanism so as to press the second folded edge 022 of the photovoltaic panel 02 between the longitudinal drain groove 2 and the pressing portion 51. Preferably, the adjusting mechanism includes a screw hole 521 provided in the supporting portion 52 and an adjusting screw 522 screwed into the screw hole 521, the adjusting screw 522 abutting against the bottom of the longitudinal drain tank 2.
Before installing the photovoltaic panel 02, the adjusting screw 522 is screwed down to increase the gap, or the press hook 5 is directly detached; when the photovoltaic panel 02 is mounted, the second flange 022 of the photovoltaic panel 02 is placed on the upper surface of the longitudinal drainage groove 2, then the longitudinal drainage groove 2 and the second flange 022 are located in the middle of the C-shaped pressing hook 5, and then the adjusting screw 522 is screwed upwards to press the second flange 022 between the pressing portion 51 and the longitudinal drainage groove 2, so that the photovoltaic panel 02 is mounted. Of course, other means than screw hole and nut fitting may be used for the adjusting means, as long as the second flange 022 can be pressed between the pressing portion 51 and the longitudinal drain groove 2, and similar alternatives fall within the scope of the present invention.
In this embodiment, as shown in fig. 5, the longitudinal drain groove 2 is a first profile, the first profile includes a connection portion 21 and an extension portion 22 extending outward from the connection portion 21 and bending upward, the extension portion 22 forms a water flowing region 221, the top end of the connection portion 21 is higher than the top end of the extension portion 22, the lateral drain groove 3 is mounted on the top end of the extension portion 22 to guide water to flow into the water flowing region 221, and the top end of the connection portion 21 forms the top surface of the above-mentioned longitudinal drain groove 2, that is, the top end of the connection portion 21 abuts against the second flange 022.
The top end of the connecting portion 21 and the pressing portion 51 of the pressing hook 5 press the second flange 022, and since the top end of the connecting portion 21 is higher than the top end of the outer extending portion 22, a gap exists between the bottom of the second flange 022 and the top end of the outer extending portion 22 after the photovoltaic panel 02 is mounted in place, and the gap can be used for accommodating the transverse drainage groove 3, so that the normal mounting of the photovoltaic panel 02 is not affected after the transverse drainage groove 3 is mounted on the top end of the outer extending portion 22, as shown in fig. 6, the transverse drainage groove 3 wraps the second flange 022 under the transverse gap between the adjacent photovoltaic panels 02, and after water falls into the transverse drainage groove 3 from the transverse gap between the photovoltaic panels 02, the water flows from the transverse drainage groove 3 to the water flowing area 221 of the longitudinal drainage groove 2; it will be appreciated that in this configuration the lateral drainage channel 3 is movable, but as long as the length of the lateral drainage channel 3 is sufficiently long, the range of movement of the lateral drainage channel 3 is only small as it approaches the length of the photovoltaic panel 02, and this small range of movement does not cause it to become disconnected from the longitudinal drainage channel 2 and therefore does not affect the water-repellent effect. Of course. In addition to this, a notch concave from top to bottom may be formed in the side surface of the longitudinal drainage channel 2, and the lateral drainage channel 3 is placed at the notch, so that water in the lateral drainage channel 3 can flow to the longitudinal drainage channel 2, and the normal installation of the photovoltaic panel 02 is not affected by the presence of the lateral drainage channel 3.
In the present embodiment, as shown in fig. 5, the connection part 21 includes a first connection piece accommodating groove 211, and the first connection piece accommodating groove 211 is used for accommodating a bolt head or a nut. The bolt head of the bolt is placed in the first connecting piece accommodating groove 211, the bolt is connected with the secondary beam 13 through a nut or a threaded connecting block, or the nut is placed in the first connecting piece accommodating groove 211 and is connected with the secondary beam 13 through the bolt, and the connection between the longitudinal drain tank 2 and the secondary beam 13 is realized in the above mode.
In the present embodiment, the connection part 21 includes a tapping screw receiving groove 212 spaced apart from the running water region 221, as shown in fig. 6, the longitudinal drain grooves 2 adjacent on the same line are connected by the sink connection member 23, the front and rear sections of the sink connection member 23 are respectively connected to the longitudinal drain grooves 2 adjacent on the same line, and the tapping screw passes through the sink connection member 23 and the tapping screw receiving groove 212 to achieve connection of the longitudinal drain grooves 2 with the sink connection member 23.
In practical applications, the length of the longitudinal drain grooves 2 is not too long for easy production and transportation, and therefore, for various practical situations, the water groove connecting member 23 is generally used to connect a plurality of longitudinal drain grooves 2 together to increase the total length of the longitudinal drain grooves 2. In the prior art, it is common practice to use self-tapping screws to pass through the sink connection member 23 and the longitudinal drain tank 2 to achieve connection of the sink connection member 23 to the longitudinal drain tank 2. However, in the prior art, the tapping screw passes through the water flowing area of the longitudinal drainage groove, so that after the tapping screw is screwed in, water slowly seeps out from the position where the tapping screw is positioned, and the waterproof effect is weakened. Therefore, the tapping screw accommodating groove 212 separated from the water flowing area 221 is additionally arranged on the longitudinal water draining groove 2, water cannot flow into the tapping screw accommodating groove 212, and the tapping screw is screwed into the tapping screw accommodating groove 212 when being screwed into the longitudinal water draining groove 2, so that the problems can be avoided. Preferably, the shape of the upper surface of the sink connecting piece 23 is consistent with the shape of the lower surface of the longitudinal drain groove 2, and then the glue can be sealed between the upper surface of the sink connecting piece 23 and the lower surface of the longitudinal drain groove 2, thereby improving the waterproof effect.

The upright post 11 and the main beam 12 are both made of the second section bar, so that the upright post 11 and the main beam 12 can be mutually used, and the production cost is reduced.
As shown in fig. 7 and 8, an oblique beam 14 may be added between the upright 11 and the main beam 12, the bolt head of the bolt is placed in the second connecting piece accommodating groove 101, the bolt is connected with the end of the oblique beam 14 through a nut or a threaded connecting block, or the nut is placed in the second connecting piece accommodating groove 101, and is connected with the end of the oblique beam 14 through the bolt, the triangular structure makes the connection between the upright 11 and the main beam 12 more stable, and meanwhile, since the upright 11 and the main beam 12 can be mutually used, too many kinds of parts do not need to be prepared when the oblique beam 14 is installed, and the installation is convenient.

Through the structure, the main beams 12 can incline relative to the ground and can incline at different angles, so that the whole photovoltaic shed frame can easily realize a height and a low height without adopting other connecting pieces with specific shapes.
In the present embodiment, as shown in fig. 7, a reinforcing rib 102 is provided between a second pair of opposite side surfaces (left and right side surfaces in fig. 7) of the second profile. Adding a stiffening rib 102 between the second pair of opposite sides can increase the strength of the second profile; meanwhile, as described above, the bolts need to pass through the second pair of opposite sides of the upright 11 and then are screwed with the nuts, and there are also cases where the bolts need to pass through the second pair of opposite sides of the main beam 12 or the upright 11 and then are screwed with the nuts in other places, and the provision of the reinforcing ribs 102 between the second pair of opposite sides can prevent the occurrence of the condition that the second pair of opposite sides are concave inward due to the pressure of the bolts, and can also indirectly improve the strength of the main beam 12 and the upright 11.
Preferably, the end parts of the main beam 12, the secondary beam 13 and the water collecting tank 4 are provided with sealing covers, and the sealing covers can avoid sharp sectional materials from scratching personnel and can also avoid water from entering the main beam 12 and the secondary beam 13.
