Detailed Embodiment

[0019] The technical solution of the present utility model will be further described below through embodiments in conjunction with the drawings.

[0020] Example 1:

[0021] In this example, a photovoltaic structure with a roof connection structure is as follows Figure 1 shown, including 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 11. A transverse water guide trough 11 is horizontally arranged between two longitudinal water guide troughs 3. The longitudinal water guide trough 3 is placed on the roof 2. A fixed groove 4 is arranged in the middle of the longitudinal water guide trough 3. 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 arranged at the position of the channel-shaped member 6 corresponding to the fixed groove. An installation bolt 9 is arranged in the through hole. A pressing member 10 and a limiting block 6 are arranged on the installation bolt. The installation bolt and the limiting member are used to limit the distance between the pressing member and the fixed groove. The pressing member 10 presses and fixes the photovoltaic module 1 on the channel-shaped member 6.

[0022] In this example, the channel-shaped member includes a mounting plate, a support plate and a cover plate. The support plates are vertically arranged downward on both sides of 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 a fixing bolt. The longitudinal water guide trough 3 is provided with a first water guide trough and a second water guide trough. The first water guide trough and the second water guide trough are located on both sides of the fixed groove. The cover plate is provided with concave portions 7 corresponding to the first water guide trough, the second water guide trough and the fixed groove. In addition, the distance between the two support plates of the channel-shaped member is equal to the width of the longitudinal water guide trough, and the height of the support plate is equal to the height of the longitudinal water guide trough. Such a setting enables the channel-shaped member to limit the longitudinal water guide trough and 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, and the cover plate bears the photovoltaic module, so that the longitudinal water guide trough does not need to bear weight, reducing the requirements for the thickness and material of the longitudinal water guide trough.

[0023] In this example, a limiting block 8 is screwed at the lower end of the screw rod of the installation bolt 9. The limiting block 8 is located in the fixed groove 4 and the upper end of the limiting block 8 abuts against the protrusions 5 on both sides of the fixed groove 4. The pressing member 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 101 on both sides and a resisting plate 102 between the pressing plates. The pressing plates 101 abut against the photovoltaic module 1. A through hole 103 for the installation bolt to pass through is arranged on the resisting plate 102. The resisting plate is arranged lower than the pressing plates to form a groove. A waterproof cover 12 is arranged on the pressing member. The waterproof cover is provided with a first buckle body 121 corresponding to the groove. The side wall of the groove is provided with a second buckle body 104. The first buckle body 121 and the second buckle body 104 are matched. When fixing the photovoltaic module, by adjusting the distance between the limiting block and the head of the installation bolt 9, the pressing member presses and fixes the photovoltaic module to the channel-shaped member. Then, the waterproof cover is covered on the pressing member, and the fixing of the waterproof cover and the pressing member is realized through the buckling of the first buckle body and the second buckle body.

[0024] Example 2:

[0025] In one embodiment of a photovoltaic structure with a roof connection structure, compared with Embodiment 1, the difference in this embodiment is that the fixing method of the photovoltaic module and the longitudinal water guide groove is different, and the limiting block is a nut. As Figure 3 shown, the head of the installation screw 9 is located in the fixing groove 4 and the head of the installation screw abuts against the protrusions 5 on both sides of the fixing groove 4. The screw of the installation bolt is arranged vertically upward, and a nut 13 is screwed onto the screw of the installation bolt. The pressing member 10 is located on the screw between the nut 13 and the head of the installation screw. When fixing the photovoltaic module, by turning the nut 13 to adjust the distance between the nut and the head of the installation bolt 9, 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 and the pressing member are fixed by the engagement of the first buckle body and the second buckle body.

Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
