At the same time, the bottom end of the spliced C frame 23 needs to be inserted into the inner side of the C bracket 24. When driving the inner rubber strip 12 to wrap around the outer side of the edge closing strip 10 through the waterproof rubber strip 11, the inner rubber strip 12 will push the corrugated rubber strip 45 to deform by using the inclination angle under the action of an external force. When the inner rubber strip 12 is installed in place, the corrugated rubber strip 45 will move to the inner side of the tooth groove 44, and then fit with the inner rubber strip 12 in the tooth groove 44 by using the rebound force. At the same time, the Z-shaped rubber strip 21 will fit with the contour of the inner rubber strip 12, so as to play an internal sealing and waterproof role and improve the waterproof effect.

[0044] When installing the Z-shaped purlin 1, the staff needs to use fixing components to fixedly connect the heat exchanger 36 to the Z-shaped purlin 1. When installing the rock wool sandwich panel 3, it will drive the copper sleeve 31, the through pipe 30, the electric three-way valve 29, the elbow 34 and the drain pipe 39 to move together, so that the elbow 34 and the drain pipe 39 can be aligned with the quick connector 35 at the same time when the rock wool sandwich panel 3 is in place and be inserted into the corresponding quick connector 35. When splicing the C-shaped frame 5, it will drive the connecting pipe 27 and the filter 28 to move together through the L-shaped plate 26, so that the filter 28 is aligned with the other end of the electric three-way valve 29, and then use fixing components to connect the electric three-way valve 29 to the filter 28. When splicing the photovoltaic panel 18, the photovoltaic panel 18 will drive the copper pipe 32 to move together through the copper plate 33, so that the bottom end of the copper pipe 32 can be placed on the copper sleeve 31 and fit with it for heat conduction.

[0045] The staff needs to connect the water delivery pipeline to the third end of the electric three-way valve 29. When the weather is sunny, the staff can manually control the electric three-way valve 29 near the elbow 34 through the controller to adjust, so that the through pipe 30 is only connected to the water delivery pipeline through the electric three-way valve 29, so that water can pass through the water delivery pipeline and the electric three-way valve 29 near the elbow 34 and flow into the inner side of the through pipe 30, and then pass through the through pipe 30 and enter the inner side of the copper sleeve 31. When the copper sleeve 31 is full of water, it will pass through the through pipe 30 near the water pump 38 and be discharged into the electric three-way valve 29 connected to one end thereof, and then pass through the electric three-way valve 29 and be discharged into the water delivery pipe. Furthermore, the heat generated by the photovoltaic panel 18 working will be absorbed by the copper plate 33 and transferred to the copper sleeve 31 through the copper pipe 32, so that the water flowing in the copper sleeve 31 can absorb and carry away the heat of the copper sleeve 31, thus realizing the cooling of the photovoltaic panel 18.

[0046] When it rains, the rain sensor 42 will sense the rain and control the electric three-way valve 29 to be only connected to the through pipe 30 and the filter 28 through the controller. At this time, the copper sleeve 31 will still be full of cooling water. The rain generated by the rain will fall into the inner side of the through port 19 and pass through the through port 19 and enter the square pipe 20. Then, under the action of gravity, it will pass through the square pipe 20 and the inner rubber strip 12 and flow into the inner side of the C plate 22, and then flow along the C plate 22 into the C frame 23. Then it will pass through the C frame 23 and fall into the inner side of the C support 24, and under the cooperation of the C support 24 and the sealing strip 25, the water will flow into the connecting pipe 27. Then, under the inclination angle and guiding action of the connecting pipe 27, it will pass through the connecting pipe 27 and flow into the filter 28 for filtering. The rainwater filtered through the filter 28 will enter the electric three-way valve 29 and then pass through the electric three-way valve 29 and flow into the inner side of the through pipe 30. Then it will pass through the through pipe 30 and enter the copper sleeve 31. The excess water in the copper sleeve 31 will overflow into the elbow 34 and enter the heat exchanger 36 along the elbow 34 through the quick connector 35 and the connecting pipeline. At the same time, after the rain sensor 42 senses the rain, it will control the fan 37 and the water pump 38 to operate through the controller, so that the water pump 38 sucks out the water in the heat exchanger 36 through the connecting pipeline and outputs it to the discharge pipe 39 through the quick connector 35, and then passes through the discharge pipe 39 and enters the through pipe 30, and then passes through the through pipe 30 and enters the copper sleeve 31 for recycling, so that the filtered rainwater can absorb heat in the copper sleeve 31, and the rainwater after absorbing heat will use the fan 37 to dissipate heat and cool down for recycling, so that the device can conveniently use rainwater to cool the photovoltaic panel 18 and save water resources.

[0047] The staff can manually control the adjustment of the electric three-way valve 29 near the elbow 34 according to the actual situation, so that the connecting pipe 30 is only connected to the water delivery pipeline through the electric three-way valve 29. Then, the water delivery pipeline connected to the electric three-way valve 29 is removed and replaced with a flushing pipeline. At the same time, the staff manually operates the controller to start the water pump 38, so that the water pump 38 sucks out the water in the heat exchanger 36 and inputs it into the cylinder sleeve through the drain pipe 39 and the connecting pipe 30, and squeezes out the water in the cylinder sleeve into the connecting pipe 30 near the elbow 34, and passes through the connecting pipe 30 and the electric three-way valve 29 into the flushing pipeline. Finally, the staff operates the flushing pipeline to spray the water onto the photovoltaic panel 18, so as to use the filtered rainwater to wash the photovoltaic panel 18, providing convenience for cleaning the photovoltaic panel 18 and saving time and water resources.

[0048] Working principle: modular installation is realized through the three-level support structure of the Z-shaped purlin 1, M guide rail 2, and M support plate 4. The Z-shaped purlin 1 forms the main roof support structure. The M guide rail 2 is adjustably fixed to the purlin by bolts 8. The M support plate 4 is inserted and fitted into the guide rail groove. The nested design of the C-shaped frame 5 and the T-shaped rubber strip 6 allows the photovoltaic panel 18 to be quickly positioned and installed through the m-shaped pressing plate 7. The horizontal and vertical splicing parts form a standard unit through the splicing combination of the support 14 and the horizontal frame 13, realizing the building block expansion of the photovoltaic array, improving the installation efficiency, and having a better splicing effect.

[0049] The system of the Z-shaped purlin 1 and the M guide rail 2 improves the wind pressure resistance. The elastic deformation design of the C-shaped frame 5 can absorb the thermal expansion amount.

[0050] Primary seal: The T-shaped rubber strip 6 is fitted with the M support plate 4 to form the bottom waterproof layer. Secondary seal: The elastic bite of the corrugated rubber strip 45 and the tooth groove 44 and the inner rubber strip 12 cooperate to form the inner side waterproof interface. Tertiary seal: The double-layer lap joint structure of the waterproof rubber strip 11 and the second rubber strip 16 forms the top waterproof barrier. Among them, the sawtooth structure of the edge strip 10 and the tooth groove 44 of the waterproof rubber strip 11 form a labyrinth drainage channel, which, combined with the elastic seal of the rubber pad 17, realizes the dynamic waterproof effect. The triple seal system can withstand a high water volume and achieve continuous non-leakage.

[0051] The three-dimensional diversion channel composed of the through port 19, the square pipe 20, and the C plate 22 realizes the directional collection of roof rainwater. The three-dimensional heat conduction network composed of the copper sleeve 31, the copper plate 33, and the copper pipe 32, combined with the heat insulation layer of the rock wool sandwich panel 3, forms a gradient heat exchange structure.

[0052] The rainwater sensor 42 is linked with the electric three-way valve 29 to realize the automatic switching of the cooling mode. The pipeline system of the integrated filter 28 supports the high-pressure flushing mode. A closed-loop cleaning circuit is formed through the water pump 38, the heat exchanger 36, and the connecting pipe 27, improving the utilization rate and functionality of rainwater. The quick-connect joint 35 design can shorten the disassembly and assembly time of the pipeline.

[0053] Although there are some modular installation or waterproof improvement solutions in the prior art, they generally lack systematic design and are difficult to take into account the coordinated optimization of rapid splicing installation, long-term waterproofing, efficient heat dissipation and rainwater utilization, which limits the large-scale promotion of photovoltaic roofs.

[0054] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
