DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions of the present utility model will be further described below through embodiments in conjunction with the drawings.

[0018] Embodiment 1:

[0019] A photovoltaic structure with a roof installation structure in this embodiment, as Figure 1As shown in the figure, it includes a photovoltaic module 1. A water guide trough fixed on the roof is arranged below the photovoltaic module. The water guide trough includes a longitudinal water guide trough 3 and a transverse water guide trough 10. A transverse water guide trough 10 is horizontally arranged between two longitudinal water guide troughs 3. The longitudinal water guide trough 3 is placed on the roof 2. A channel-shaped member 6 is covered on the longitudinal water guide trough. The channel-shaped member 6 is horizontally arranged and fixedly arranged on the roof 2. A through hole is provided in the middle of the channel-shaped member 6. An installation bolt 7 is provided in the through hole. A pressing member 9 and a limiting block 8 are provided on the installation bolt. The installation bolt 7 and the limiting block 8 are used to limit the distance between the pressing member 9 and the channel-shaped member 6. The pressing member 9 presses and fixes the photovoltaic module 1 on the channel-shaped member 6.

[0020] In this embodiment, the channel-shaped member includes a mounting plate, a support plate and a cover plate. The support plates are arranged obliquely downward on both sides of the cover plate. The support plates and the cover plate form a first limiting groove 5. A concave second limiting groove 4 is provided near the first limiting groove on the cover plate. The mounting plate is horizontally arranged at the lower end of the support plate. The mounting plate is fixedly arranged on the roof through fixing bolts. The longitudinal water guide trough 3 includes a water guide trough in the middle and bending limiting parts on both sides of the water guide trough. The bending limiting parts extend into the first limiting groove. The second limiting groove extends into the water guide trough and abuts against the side wall of the water guide trough. With such a setting, the channel-shaped member can limit the longitudinal water guide trough to prevent the longitudinal water guide trough from moving left and right. At the same time, the cover plate of the channel-shaped member is arranged higher than the longitudinal water guide trough. The cover plate bears the photovoltaic module, so that the longitudinal water guide trough does not need to bear the weight, reducing the requirements for the thickness and material of the longitudinal water guide trough.

[0021] In this embodiment, a limiting block 8 is screwed to the lower end of the screw rod of the installation bolt 7. The limiting block is a nut. The limiting block 8 is located below the channel-shaped member and the upper end of the limiting block 8 abuts against the channel-shaped member 6. The pressing member 9 is located at the upper end of the screw rod of the installation bolt. As Figure 2 shown, the pressing member is in an inverted channel shape, including pressing plates 91 on both sides and a resisting plate 92 between the pressing plates. The pressing plates 91 abut against the photovoltaic module. A through hole 93 for the installation bolt to pass through is provided on the resisting plate 92. The resisting plate is arranged lower than the pressing plates to form a groove. A waterproof cover 11 is provided on the pressing member. The waterproof cover is provided with a first buckle body 111 corresponding to the groove. The side wall of the groove is provided with a second buckle body 94. The first buckle body 111 and the second buckle body 94 are matched. When fixing the photovoltaic module, by adjusting the distance between the limiting block and the head of the installation bolt 7, the pressing member presses and fixes the photovoltaic module to the channel-shaped member. Then, a waterproof cover is covered on the pressing member, and the fixation of the waterproof cover and the pressing member is realized through the buckling of the first buckle body and the second buckle body.

[0022] Embodiment 2:

[0023] A photovoltaic structure with a roof installation structure in this embodiment is different from Embodiment 1 in that the fixing method of the photovoltaic module and the longitudinal water guide trough in this embodiment is different. As Figure 3As shown, the head of the installation screw 7 is located below the channel-shaped member 6 and the head of the installation screw abuts against the channel-shaped member 6. The screw of the installation bolt is arranged vertically upward. A limit block 8 is screwed onto the screw of the installation bolt. The pressing member 9 is located on the screw between the nut 8 and the head of the installation screw. When fixing the photovoltaic module, by adjusting the distance between the limit block and the head of the installation bolt, the pressing member presses and fixes the photovoltaic module onto the channel-shaped member. Then, a waterproof cover is placed on the pressing member, and the waterproof cover is fixed to the pressing member through the engagement of the first buckle body and the second buckle body.
