One end of the heat exchanger 36 is connected to a quick-connect connector 35 through a pipeline, and the quick-connect connector 35 is plugged into the other end of the elbow 34, and the output end of the water pump 38 is also connected to the quick-connect connector 35. The heat exchanger 36 can provide a winding flow channel for water, which is convenient for heat exchange and cooling of the water.

[0136] Auxiliary parts include:

[0137] The L-plate 26 is supported on the inner side of the C-shaped frame 5 and fixedly wrapped around the connecting pipe 27;

[0138] A rain sensor 42 is fixed on the photovoltaic panel 18;

[0139] One end of the through pipe 30 passes through both sides of the copper sleeve 31 and is fixed thereto;

[0140] An electric three-way valve 29, one end of which is disposed at the other end of the through pipe 30 and is electrically connected to the rain sensor 42 via a controller;

[0141] The filter 28 is fixed to the other end of the electric three-way valve 29 and connected to the connecting pipe 27.

[0142] Specifically, the L-plate 26 can provide stable support for the connecting pipe 27 under the support of the C-shaped frame 5, and the L-plate 26 can make the C-shaped frame 5 more solid to prevent deformation. The copper sleeve 31 can provide stable support for the through pipe 30. The through pipe 30 on one side of the copper sleeve 31 passes through the rock wool sandwich panel 3 and is connected to the drain pipe 39, and the drain pipe 39 is connected to the quick-plug connector 35 connected to the output end of the water pump 38. The filter 28 can provide a through channel for water and can filter impurities in the water.

[0143] In the actual application process of this embodiment, the staff needs to use the fixing parts to fix the multiple rock wool sandwich panels 3 to the M guide rail 2 through the fixing parts when installing the M guide rail 2, and at the same time ensure that the multiple rock wool sandwich panels 3 are spliced ​​together through the splicing plates 43. When installing the C-shaped frame 5, the C-shaped frame 5 will drive the connecting pipe 27 and the C support 24 to move together through the L plate 26, so that the C support 24 can be spliced ​​together in groups of two through the sealing strip 25. When the receiving edge strip 10 is inserted, the edge strip 10 will drive the C plate 22 and the C frame 23 to move together through the Z-shaped rubber strip 21 under the action of external force, so that the C plate 22 and the C The frames 23 can be spliced ​​together in groups of two through the sealing strip 25. At the same time, the bottom end of the spliced ​​C frame 23 needs to be inserted into the inner side of the C support 24. When the inner strip 12 is driven by the waterproof strip 11 to wrap around the outside of the edge strip 10, the inner strip 12 will use the inclination angle to push the corrugated strip 45 to deform under the action of external force. When the inner strip 12 is installed in place, the corrugated strip 45 will move to the inside of the tooth groove 44, and then use the rebound force to fit with the inner strip 12 in the tooth groove 44. At the same time, the Z-shaped strip 21 will fit with the contour of the inner strip 12, thereby playing an internal sealing and waterproofing role, and improving the waterproof effect.

[0144] When installing the Z-shaped purlin 1, the staff needs to use fixing components to fix the heat exchanger 36 to the Z-shaped purlin 1. When installing the rock wool sandwich panel 3, the copper sleeve 31, the through pipe 30, the electric three-way valve 29, the elbow 34 and the row pipe 39 will be driven to move together, so that the elbow 34 and the row pipe 39 can be aligned with the quick-plug connector 35 when the rock wool sandwich panel 3 is in place, and plugged into the quick-plug connector 35 at the corresponding position. When splicing the C-shaped frame 5, it will drive the connecting pipe 27 and the filter 28 to move together through the L-plate 26, so that the filter 28 is aligned with the other end of the electric three-way valve 29, and then use the 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 tube 32 to move together through the copper plate 33, so that the bottom end of the copper tube 32 can be placed on the copper sleeve 31 and fit it for heat conduction.

[0145] The staff needs to connect the water delivery pipeline with the third end of the electric three-way valve 29. When the weather is clear, the staff can manually control the electric three-way valve 29 near the elbow 34 through the controller to adjust it so that the through pipe 30 is 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 into the inner side of the through pipe 30, and pass through the through pipe 30 into 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 pass through the electric three-way valve 29 to be discharged into the water delivery pipe. Then, the heat generated by the photovoltaic panel 18 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 take away the heat of the copper sleeve 31, thereby achieving cooling of the photovoltaic panel 18.

[0146] When it rains, the rain sensor 42 senses the rain and controls the electric three-way valve 29 to be connected only to the through-pipe 30 and the filter 28 through the controller. At this time, the copper sleeve 31 is still full of cooling water, and the rainwater generated by the rain will fall to the inner side of the through-port 19 and pass through the through-port 19 into the square tube 20. Then, under the action of gravity, it passes through the square tube 20 and the inner rubber strip 12 and flows into the inner side of the C-plate 22, and flows into the C-frame 23 along the C-plate 22, and then passes through the C-frame 23 and falls to the inner side of the C-support 24. Under the cooperation of the C-support 24 and the sealing strip 25, the water flows into the connecting pipe 27. Then, under the inclination angle and guiding effect of the connecting pipe 27, it passes through the connecting pipe 27 and flows into the filter 28 for filtration. The rainwater filtered by the filter 28 enters the electric three-way valve 29 and passes through the electric three-way valve 29 and flows into the inner side of the through-pipe 30. The water passes through the pipe 30 and then enters the copper sleeve 31. The excess water in the copper sleeve 31 overflows into the elbow 34 and enters the heat exchanger 36 along the elbow 34 through the quick-plug connector 35 and the connecting pipe. At the same time, the rain sensor 42 controls the fan 37 and the water pump 38 through the controller after sensing rain, so that the water pump 38 sucks the water out of the heat exchanger 36 through the connecting pipe and outputs it to the drain pipe 39 through the quick-plug connector 35, and passes through the drain pipe 39 to enter the pipe 30, and then passes through the pipe 30 to enter the copper sleeve 31 for recycling, so that the filtered rainwater can absorb heat in the copper sleeve 31. After absorbing heat, the rainwater enters the heat exchanger 36 and uses the fan 37 to dissipate heat and cool it for recycling, so that the device can conveniently use rainwater to cool the photovoltaic panel 18 and save water resources.

[0147] The staff can manually control the electric three-way valve 29 near the elbow 34 according to the actual needs, so that the through pipe 30 is connected to the water delivery pipeline only through the electric three-way valve 29, and 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 controller is manually operated 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 through pipe 30, and squeezes the water in the cylinder sleeve into the through pipe 30 near the elbow 34, and passes through the through pipe 30 and the electric three-way valve 29 into the flushing pipeline. Finally, the staff operates the flushing pipeline to spray water onto the photovoltaic panel 18, so that the filtered rainwater can be used to flush the photovoltaic panel 18, which provides convenience for cleaning the photovoltaic panel 18 and saves time and water resources.

[0148] The working principle is modular installation achieved through a three-level support structure: Z-shaped purlins 1, M-shaped guide rails 2, and M-shaped support plates 4. The Z-shaped purlins 1 form the main roof support structure, the M-shaped guide rails 2 are adjustably fixed to the purlins via bolts 8, and the M-shaped support plates 4 are plug-in inserts embedded in the guide rail grooves. The nested design of the C-shaped frame 5 and T-shaped rubber strips 6 allows for quick positioning and installation of the photovoltaic panels 18 using the M-shaped pressure plate 7. The horizontal and vertical components are combined through the support 14 and the horizontal frame 13 to form a standard unit, realizing a modular expansion of the photovoltaic array, improving installation efficiency and achieving better splicing effects.

[0149] The Z-shaped purlin 1 and M-guide rail 2 system improves the wind pressure resistance, and the elastic deformation design of the C-shaped frame 5 can absorb thermal expansion.

[0150] First-level sealing: the T-shaped rubber strip 6 and the M-support plate 4 are embedded to form a bottom waterproof layer; second-level sealing: the elastic bite of the corrugated rubber strip 45 and the tooth groove 44 and the cooperation of the inner rubber strip 12 form an inner lateral waterproof interface; third-level sealing: the double-layer overlap structure of the waterproof rubber strip 11 and the second rubber strip 16 forms a top waterproof barrier; the serrated structure of the edge strip 10 and the tooth groove 44 of the waterproof rubber strip 11 form a labyrinth-like drainage channel, which cooperates with the elastic sealing of the rubber pad 17 to achieve a dynamic waterproof effect. The triple sealing system can withstand high water volume and achieve continuous leakage-free.

[0151] The three-dimensional guide channel formed by the through opening 19, square tube 20 and C plate 22 realizes the directional collection of roof rainwater; the three-dimensional heat conduction network composed of copper sleeve 31, copper plate 33 and copper tube 32, combined with the insulation layer of rock wool sandwich panel 3, forms a gradient heat exchange structure.

[0152] The rain sensor 42 is linked to the electric three-way valve 29 to realize automatic switching of the cooling mode; the pipeline system of the integrated filter 28 supports the high-pressure flushing mode, and forms a closed-loop cleaning circuit through the water pump 38, heat exchanger 36, and connecting pipe 27, which improves the utilization rate and functionality of rainwater, and the quick-plug connector 35 design can shorten the time for disassembly and assembly of the pipeline.

[0153] Although there are some modular installation or waterproofing improvement solutions in the existing technology, they generally lack systematic design, making it difficult to balance the coordinated optimization of rapid splicing and installation, long-term waterproofing, efficient heat dissipation and rainwater utilization, which limits the large-scale promotion of photovoltaic roofs.

[0154] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
