[0040] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0041] like Figure 1 , 2As shown in Figure 3, an embodiment of the present invention discloses a distributed photovoltaic power generation system for a flexible roof, comprising four insulation tubes 1 arranged in a matrix, each of the insulation tubes 1 is fixedly connected to a support rod 2, the top ends of the four support rods 2 are commonly connected to a mounting frame 3, a photovoltaic panel 4 is arranged on the mounting frame 3, the photovoltaic panel 4 and the insulation tube 1 are fixedly connected to a roof steel frame, the bottom end of the support rod 2 is fixedly connected to an arc-shaped curved base, the base is fixedly connected to the insulation tube 1, a flexible roof 5 is arranged on the roof, and a waterproof membrane 6 is arranged between the arc-shaped curved base and the flexible roof 5.

[0042] Specifically, when in use, the photovoltaic panel 4 receives sunlight, generates electricity, and the thermal insulation tube 1, the support rod 2, and the mounting frame 3 mount the photovoltaic panel 4 on the flexible roof.

[0043] By setting the photovoltaic panel 4, photovoltaic power generation can be carried out on the flexible roof 5. By directly fixing the insulation tube 1 to the roof steel frame, the photovoltaic panel can be prevented from shaking when subjected to wind force, thereby causing the flexible roof to tear. At the same time, by setting the waterproof membrane 6, the support rod 2 and the flexible roof 5 can be sealed to prevent water from entering the interior of the roof through the gap between the support rod 2 and the flexible roof 5.

[0044] Furthermore, the waterproof membrane 6 is fixedly connected to the arc-shaped curved surface base and the flexible roof 5 by gluing.

[0045] The waterproof membranes 6 are connected by gluing so that the waterproof membranes 6 are sealed to prevent condensation water from entering the roof.

[0046] like Figure 3 As shown, a fireproof, safe and efficient output photovoltaic power generation module 7 is fixedly connected to the back of the photovoltaic panel 4. The fireproof, safe and efficient output photovoltaic power generation module 7 includes a double-sided double-glass photovoltaic module and a photovoltaic module-level optimizer.

[0047] By equipping each module in the string inverter power generation system with a photovoltaic module-level optimizer to track the maximum power point (MPP) of the photovoltaic module in real time, the power generation loss caused by external reasons (such as weak light, partial shading, inappropriate orientation, etc.) of the photovoltaic module can be reduced, and the power generation efficiency can be improved by combining the white reflective characteristics of double-sided double-glass modules and waterproof membranes; the module-level shutdown, monitoring and detection functions of the optical module-level optimizer can be used to achieve safe power generation.

[0048] Furthermore, the fireproof, safe and efficient output photovoltaic power generation module 7 is a prior art and will not be described in detail.

[0049] like Figure 4 , 5As shown in , 6 , a snow removal mechanism 8 is arranged on the upper side of the photovoltaic panel 4 , and the snow removal mechanism 8 includes a scraper 81 slidably arranged on the photovoltaic panel 4 , and the scraper 81 includes a scraper plate 811 slidably connected to the photovoltaic panel 4 .

[0050] Specifically, when in use, when snow removal is required, the snow removal mechanism 8 is slid, and the scraper plate 811 slides on the photovoltaic panel 4 to scrape the accumulated snow off the photovoltaic panel 4.

[0051] By setting the scraper 81 , when snow accumulates on the photovoltaic panel 4 , the scraper plate 811 can be moved to scrape the snow off the photovoltaic panel 4 , so as to prevent the accumulated snow from affecting the power generation efficiency of the photovoltaic panel 4 .

[0052] like Figure 6 , 7 As shown, the scraper plate 811 is arranged on the mounting plate 812, and a through groove with upper and lower openings is opened in the mounting plate 812, and a baffle 813 is slidably connected in the through groove, and the bottom end of the baffle 813 is located at the lower side of the mounting plate 812, and the baffle 813 is fixedly connected to the scraper plate 811. The scraper plate 811 is made of sponge material, and triangular plates 814 are symmetrically arranged at both ends of the photovoltaic panel 4, and the hypotenuse of the triangular plate 814 can abut against the top end of the baffle 813.

[0053] Specifically, when snow is removed, the mounting plate 812 moves, the mounting plate 812 drives the scraping plate 811 to move, the scraping plate 811 drives the baffle 813 to move, the scraping plate 811 scrapes the snow on the photovoltaic panel 4, and the baffle 813 blocks the scraped snow to prevent the snow from piling up too high during the scraping process and passing over the scraping plate 811; when the baffle 813 moves to the end of the photovoltaic panel 4, the baffle 813 abuts against the triangular plate 814, and under the action of the hypotenuse of the triangular plate 814, the baffle 813 moves downward, and the baffle 813 hits the scraping plate 811. 11 is squeezed to squeeze out the water in the scraper plate 811, and then the mounting plate 812 is moved in the opposite direction to reset. The scraper plate 811 after squeezing out the water scrapes the photovoltaic panel 4 again. When the baffle plate 813 abuts against the triangular plate 814 at the end, the scraper plate 811 is squeezed again, and then the mounting plate 812 is moved again. This is repeated several times to first scrape off the snow on the photovoltaic panel 4, and then absorb and squeeze out the water on the photovoltaic panel 4 in the next few times to avoid excessive water accumulation on the photovoltaic panel 4, ice on the photovoltaic panel 4, and affect the power generation efficiency of the photovoltaic panel 4.

[0054] By setting the baffle 813, the scraper plate 811 can be assisted in processing the accumulated snow. Meanwhile, by setting the triangular plate 814, the scraper plate 811 can be squeezed to squeeze out the water on the scraper plate 811, thereby preventing the water from freezing on the photovoltaic panel 4 and affecting the power generation efficiency of the photovoltaic panel 4.

[0055] like Figure 5 , 7 As shown in Figure 10, a liquid adding component 82 is provided in the baffle 813, and the liquid adding component 82 includes a liquid storage chamber 821 opened in the baffle 813. The top end of the liquid storage chamber 821 is connected with a connecting pipe 822, and the connecting pipe 822 is connected to the antifreeze storage tank. The bottom wall of the liquid storage chamber 821 is provided with eight drainage holes 823 at equal intervals along a straight line direction, and the drainage holes 823 are connected to the wiper plate 811.

[0056] Specifically, when in use, antifreeze is added to the liquid storage chamber 821 through the connecting pipe 822 , and the antifreeze enters the scraper plate 811 through the drainage hole 823 , and then is smeared on the photovoltaic panel 4 through the movement of the scraper plate 811 .

[0057] By providing the liquid adding member 82 , the antifreeze agent can be applied to the photovoltaic panel 4 through the scraper plate 811 , thereby reducing the possibility of freezing of the photovoltaic panel 4 .

[0058] like Figure 5 , 10 As shown, the scraper 81 is arranged on the photovoltaic panel 4 through a moving part 83, and the moving part 83 includes an electromagnetic slide rail 831 fixedly connected to the photovoltaic panel 4, and an electromagnetic slider 832 is slidably connected in the electromagnetic slide rail 831, and the electromagnetic slider 832 is fixedly connected to the mounting plate 812.

[0059] Specifically, when in use, when the mounting plate 812 needs to be moved, the electromagnetic slider 832 is started, and the electromagnetic slider 832 slides in the electromagnetic slide rail 831 , and the electromagnetic slider 832 drives the mounting plate 812 to move.

[0060] By setting the moving part 83 , the mounting plate 812 can be driven to move, so that the scraping plate 811 can scrape the surface of the photovoltaic panel 4 .

[0061] Furthermore, the electromagnetic slide rail 831 and the electromagnetic slider 832 are prior art and will not be described in detail.

[0062] like Figure 5 , 7 As shown in FIG. 10 , a vibration member 84 is provided on the electromagnetic slider 832, and the vibration member 84 includes a fixing rod 841 fixedly connected to the electromagnetic slider 832, and a downwardly opening sliding groove 842 is provided in the fixing rod 841, and a sliding rod 843 is slidably connected in the sliding groove 842, and a chamfer is provided at the bottom end edge of the sliding rod 843. A mounting rod 844 is provided on the flexible roof 5, and twenty abutment blocks 845 are evenly spaced along the length direction thereof, and the bottom end of the mounting rod 844 can abut against the abutment block 845.

[0063] Specifically, during use, when the electromagnetic slider 832 moves, the electromagnetic slider 832 drives the mounting rod 844 to move, and the mounting rod 844 drives the sliding rod 843 to move. During the movement of the sliding rod 843, it abuts against the abutment block 845 in turn, causing the fixed rod 841 to vibrate, and the fixed rod 841 transmits the vibration to the photovoltaic panel 4, assisting the scraper plate 811 to process the accumulated snow.

[0064] By setting the vibration member 84, the sliding rod 843 can vibrate when the scraping plate 811 scrapes the accumulated snow. The sliding rod 843 drives the photovoltaic panel 4 to vibrate through the fixed rod 841, thereby assisting the scraping plate 811 in processing the accumulated snow.

[0065] like Figure 8 As shown, a lifting member 85 is provided between the mounting frame 3 and the support rod 2, and the two support rods 2 on one side are hinged to the mounting frame 3. The lifting member 85 includes an electric push rod embedded in the support rod 2 on the other side, and the output end of the electric push rod is hinged with a slider, and a slide rail is provided on the bottom surface of the mounting frame 3, and the slider is slidably connected in the slide rail.

[0066] Specifically, when dealing with snow, start the electric push rod, and the output end of the electric push rod drives the slider to move upward, and at the same time the slider moves in the slide rail to tilt the photovoltaic panel 4; when squeezing water from the scraper plate 811, start the electric push rod to tilt the photovoltaic panel 4, so that the water discharged from the scraper plate 811 flows directly to the ground.

[0067] By setting the lifting member 85, the tilt angle of the photovoltaic panel 4 can be changed, which facilitates the photovoltaic panel 4 to adjust the lighting angle, and can also assist in the discharge of accumulated snow and accumulated water.

[0068] Furthermore, the electric push rod is a prior art and will not be described in detail.

[0069] In addition, the present invention also provides a method for installing a distributed photovoltaic power generation system on a flexible roof, which is characterized by comprising the following steps:

[0070] Step 1: Install the thermal insulation tube 1 on the flexible roof 5 through the installation device 9;

[0071] Step 2: Paste the arc-shaped curved base onto the thermal insulation tube 1;

[0072] Step 3: Fix the support rod 2 to the curved surface base;

[0073] Step 4: Install the mounting frame 3 on the support rod 2;

[0074] Step 5: Install the photovoltaic panel 4 on the mounting frame 3.

[0075] like Fig.11As shown, the installation device 9 includes a base frame 91, a cold welding machine 92 is slidably connected to the base frame 91, an annular metal detector 93 is fixedly connected to the cold welding machine 92, and a welding gun 94 is connected to the output end of the cold welding machine 92.

[0076] Specifically, when in use, the base frame 91 is placed on the flexible roof 5, and then the metal detector 93 is started, and the cold welding machine 92 is slid. The cold welding machine 92 drives the metal detector 93 to move. The metal detector 93 detects the peak position of the roof corrugated steel sheet, connects the metal nail to the peak position, and then welds the metal nail to the peak position of the corrugated steel sheet through the cold welding machine 92 and the welding gun 94, and then connects the insulation tube 1 to the cold welding nail.

[0077] By setting the mounting device 9, the wave crest position of the corrugated steel sheet can be detected, and then the heat preservation tube 1 is connected to the corrugated steel sheet by welding with metal nails and a cold welding machine.

[0078] Furthermore, the cold welding machine 92 and the metal detector 93 are prior art and will not be described in detail.
