[0050] The photovoltaic module and corrugated steel sheet integrated roof power generation system provided by the present invention includes a roof support structure, a corrugated steel sheet fixed on the roof support structure, a locking support 4 for locking and fixing the corrugated steel sheet through the first locking portion 16 and the second locking portion 17 of the adjacent corrugated steel sheet, and a photovoltaic module 8 fixed above the convex main support portion 11 of the corrugated steel sheet by a pressing block 6, and a temperature control cleaning mechanism is also provided between the photovoltaic module 8 and the corrugated steel sheet.

[0051] The roof support structure can adopt structures such as roof purlin 01. The adjacent corrugated steel sheets are locked to the locking support 4 by the first locking part 16 and the second locking part 17, and then fixed to the roof purlin 01 by the locking support 4. The bottom of the main support part 11 is also fixed to the roof purlin 01. The photovoltaic module 8 is pressed and fixed by connecting the main support part 11 through the pressing block 6. The installation is convenient and reliable, which not only ensures that the photovoltaic module 8 is installed in place, but also simplifies the construction process. The first locking part 16 and the second locking part 17 cooperate with each other to improve the waterproof performance of the corrugated steel sheet. The photovoltaic module 8 is arranged alternately through the roof formed by the convex main support part 11 and the corrugated steel sheet. The photovoltaic roof power generation system is cooled and cleaned by the temperature control cleaning mechanism to improve the power generation efficiency and reduce the risk of fire.

[0052] The photovoltaic module and corrugated steel sheet integrated roof power generation system provided by the present invention is introduced in more detail below with reference to the accompanying drawings and specific embodiments.

[0053] Please refer to Figures 1 to 3 In an optional embodiment provided by the present invention, the photovoltaic module and corrugated steel sheet integrated roof power generation system includes a corrugated steel sheet, a photovoltaic module 8 and a locking support 4, and a pressing block 6 for pressing and fixing the photovoltaic module 8 to the corrugated steel sheet. In this embodiment, a convex main support portion 11 is provided in the center of the corrugated steel sheet in the width direction, and the corrugated steel sheet also includes a first locking portion 16 and a second locking portion 17 respectively located on both sides of the corrugated steel sheet in the width direction, and the first locking portion 16 is used to cooperate and lock with the second locking portion 17 of the adjacent corrugated steel sheet and the locking support 4. The photovoltaic module 8 is fixed above the adjacent main support portion 11 by the pressing block 6, and the bottom of the main support portion 11 is fixed to the roof purlin 01.

[0054] Specifically, the corrugated steel sheet includes a first corrugated steel sheet 1, a main supporting portion 11 is arranged in the middle of the first corrugated steel sheet 1 and protrudes upward, a concave groove 12 is arranged in the center of the main supporting portion 11, and the main supporting portion 11 is fixed to the roof purlin 01 through a U-shaped support 3; concave drainage grooves 18 are arranged between the first locking portion 16 and the main supporting portion 11, and between the second locking portion 17 and the main supporting portion 11, and convex reinforcing ribs 19 are arranged between adjacent drainage grooves 18.

[0055] The first locking edge portion 16, the drainage groove 18, the main support portion 11, the groove 12 and the second locking edge portion 17 of the first corrugated steel sheet 1 are all formed by bending a steel sheet or a color steel sheet in a certain direction. In other words, the groove 12 of the main support portion 11 is formed by bending a steel sheet or a color steel sheet downward along the upper end surface of the main support portion 11, and the outer wall of the groove 12 and the inner wall of the two side walls of the main support portion 11 are hollow, so that the U-shaped support 3 can be clamped and fixed between the outer wall of the groove 12 and the inner wall of the two side walls of the main support portion 11. The U-shaped support 3 is fixed to the roof purlin 01 by self-tapping screws 9 penetrating the bottom of the seat. The U-shaped support 3 is connected and fixed with the main support portion 11 and the groove 12, avoiding the use of punching fixation, thereby improving the anti-leakage performance of the photovoltaic roof power generation system. And the U-shaped support 3 is clamped and fixed to improve the stability and wind resistance of the roof system.

[0056] The temperature control cleaning mechanism is set up as follows Figure 2 As shown, it includes a water tank 22 arranged on the ground, a water pump 23 connected to the water tank 22, the water outlet of the water pump 23 is connected to the water spray pipe 20 through a pipe, and a solenoid valve 24 is arranged between the water spray pipe 20 and the water pump 23; the solenoid valve 24 and the water pump 23 are connected to a control cabinet 25, and the start of the water pump 23 and the opening of the solenoid valve 24 are controlled by the control cabinet 25. The control cabinet 25 belongs to the conventional setting in this field, and the control cabinet 25 is not described in detail here. The photovoltaic modules 8 are laid and fixed in rows above the main support part 11 of the corrugated steel plate, and a certain width of gap is reserved between two adjacent rows of photovoltaic modules 8, which usually corresponds to the drainage groove 18 of the corrugated steel plate, and the water spray pipe 20 is laid and fixed in the drainage groove 18.

[0057] Furthermore, the temperature control cleaning mechanism also includes a temperature sensor, which is adhered and fixed to the back of the photovoltaic module 8 and connected to the control cabinet 25. When the temperature sensor detects that the temperature on the back of the photovoltaic module 8 is higher than a preset value, the temperature signal is sent to the control center of the control cabinet 25. The control cabinet 25 controls the solenoid valve 24 to open and the water pump 23 to start to send water to the water spray pipe 20. The water spray pipe 20 sprays water to cool the photovoltaic module 8, thereby improving the power generation efficiency of the photovoltaic module 8 and the degree of automation of the operation and maintenance of the photovoltaic roof power generation system. Of course, the water pump 23 and the solenoid valve 24 can also be manually controlled according to actual needs, so that the water spray pipe 20 sprays water to clean the photovoltaic module 8. The above-mentioned preset temperature value can be adjusted according to the material, season and regional factors of the photovoltaic module 8.

[0058] To optimize the water spraying effect, the water spraying pipe 20 is connected to the spray head 21. Specifically, a decorative cover plate 26 is provided above the drainage trough 18 and the water spraying pipe 20, that is, between the adjacent rows of photovoltaic modules 8. Figure 1 and Fig.14 As shown, the decorative cover plate 26 has water spray holes at both ends, and the spray head 21 is connected to the water spray pipe 20 through the water spray holes. The water spray pipe 20 is fixed in the drain groove 18 by a water pipe clamp 27. The structure of the water pipe clamp 27 is as shown in FIG. Fig.15 As shown, it includes a horizontal part and a water pipe groove connecting the horizontal part, the horizontal part is connected and fixed to the main support part 11, and the water pipe groove is bent and extended downward along the horizontal part to form a semi-cylindrical shell, and the water spray pipe 20 is clamped and fixed in the water pipe groove. For multiple rows of photovoltaic modules 8, the setting of the decorative cover plate 26 and the nozzle 21 can be set at a certain preset interval, and the setting of the decorative cover plate 26 and the nozzle 21 meets the water spray cooling and cleaning requirements of all photovoltaic modules 8.

[0059] The following is an explanation of the connection and fixation of the corrugated steel sheet and the connection and support of the photovoltaic module 8 and the corrugated steel sheet. Figure 3 and Figure 5 To optimize the above embodiment, the two side walls of the main support portion 11 are bent in a downward direction close to the center of the groove 12 to form a first bent edge 14. The first bent edge 14 is bent and extended to the same height as the bottom of the groove 12, and then bent downward away from the center of the groove 12 to form a second bent edge 15. The bottom of the second bent edge 15 extends horizontally to both sides and bends to form a drainage groove 18. Fig. 9 As shown, the top sides of the U-shaped support 3 are folded outward and tilted downward toward the U-shaped support 3 to form a pair of bent fitting portions 31 with an outer contour approximately in the shape of a triangular prism on both sides of the top of the U-shaped support 3 .

[0060] The side wall of the first bending edge 14 of the main support part 11 and the groove 12 are approximately hollow dovetail-shaped, and a slot hole for the bending matching part 31 of the U-shaped support 3 to be clamped is formed between the inner wall of the first bending edge 14 and the outer wall of the groove 12. During installation, the U-shaped support 3 is first fixed to the roof purlin 01 by self-tapping screws 9, and then the slot hole between the first bending edge 14 of the main support part 11 of the first corrugated steel sheet 1 and the outer wall of the groove 12 is aligned with the bending matching part 31 at the top of the U-shaped support 3 for sliding installation. The matching structure of the bending matching part 31 and the slot hole of the inner wall of the first bending edge 14 and the outer wall of the groove 12 further improves the stability and wind-proof ability of the first corrugated steel sheet 1.

[0061] The first corrugated steel plate 1 is provided with a first locking portion 16 and a second locking portion 17 on both sides of the width direction. The structure of the first locking portion 16 and the second locking portion 17 and the cooperation with the locking support 4 can be referred to Figure 4 , Figure 7 , Figure 8 and Fig. 9 The first locking edge portion 16 is bent in a boss shape, and the bottom of the boss forms a groove for accommodating the locking edge support 4 and the second locking edge portion 17. The second locking edge portion 17 is bent at a right angle into a mouth-shaped cross section with an opening. The second locking edge portion 17 is clamped in the groove at the bottom of the boss of the first locking edge portion 16. The locking edge support 4 specifically adopts a Z-type support, and the base of the Z-type support is fixed to the roof purlin 01 by self-tapping screws 9. The second locking edge portion 17 is pressed on the bottom surface of the top of the Z-type support, and is placed in the groove at the bottom of the boss of the first locking edge portion 16 together with the Z-type support, and then the first locking edge portion 16 and the Z-type support are fixed as needed.

[0062] The matching structure of the first locking edge portion 16, the second locking edge portion 17 and the Z-shaped support reduces the number of holes for self-tapping screws 9 to fix, and improves the anti-leakage performance of the photovoltaic roof power generation system under the premise of ensuring the stability of the photovoltaic roof power generation system. The locking structure of the first locking edge portion 16, the second locking edge portion 17 and the locking edge support 4 plays the role of connecting the adjacent first corrugated steel sheet 1 or corrugated steel sheet, and together constitutes a complete roof system. The structure of the first locking edge portion 16 and the second locking edge portion 17 can be flexibly set according to needs, such as being set to a boss-like structure like the first locking edge portion 16, and being successively erected on the top of the locking edge support 4, and can also be fixed by self-tapping screws 9 when necessary.

[0063] like Figure 7 , Figure 8 and Fig.10 As shown, in order to further optimize the above embodiment, the edge of the bottom surface of the top of the Z-shaped support is also provided with a locking rib 41 extending obliquely downward toward the base of the Z-shaped support, and the second locking portion 17 is arranged to fit the bottom surface of the top of the Z-shaped support, and is clamped at the locking rib 41 by bending the opening edge, thereby improving the reliability and sealing of the connection between the second locking portion 17 and the locking support 4.

Different from the first corrugated steel sheet 1, the second corrugated steel sheet 2 is not provided with the main support portion 11, and the first locking edge portion 16 and the second locking edge portion 17 of the corrugated steel sheet can also be used to lock with the second locking edge portion 17 and the first locking edge portion 16 of the first corrugated steel sheet 1 to the locking support 4 respectively.

[0065] In the above embodiment, the first corrugated steel sheet 1 and the second corrugated steel sheet 2 can be connected alternately as needed, that is, the first corrugated steel sheet 1-the second corrugated steel sheet 2-the first corrugated steel sheet 1-

[0066] The first corrugated steel sheet 1 and the second corrugated steel sheet 2 are arranged in a manner such as first corrugated steel sheet 1-first corrugated steel sheet 1-second corrugated steel sheet 2..., and can also be arranged in an arrangement structure such as first corrugated steel sheet 1-first corrugated steel sheet 1-second corrugated steel sheet 2-first corrugated steel sheet 1-first corrugated steel sheet 1-second corrugated steel sheet 2... according to the support requirements and arrangement gap of the photovoltaic module 8. The size specifications of the first locking edge portion 16 and the second locking edge portion 17 on both sides of the first corrugated steel sheet 1 and the second corrugated steel sheet 2 are exactly the same, so that the first corrugated steel sheet 1 and the second corrugated steel sheet 2 can be arranged and connected in any order according to the support requirements of the photovoltaic module 8.

[0067] In the above embodiment, the photovoltaic module 8 is connected and fixed to the corrugated steel sheet in the following manner.
