[0001] The present invention relates to the technical field of photovoltaic roofing, and in particular to a photovoltaic roofing system. Background Art

[0002] Photovoltaic roof refers to a new type of building structure that combines solar photovoltaic modules with building roofs, absorbs solar energy through photovoltaic modules and converts it into electrical energy. It not only has the wind and rain protection and heat insulation functions of traditional roofs, but can also generate clean energy. It is an important combination of building energy conservation and renewable energy utilization.

[0003] Traditional photovoltaic roofs use metal tracks to suspend photovoltaic panels, resulting in a large airflow channel between the photovoltaic panels and the metal tiles.

The wind resistance is increased by setting up wind-resistant components. Different wind-resistant components resist wind in different ways, including: The I-shaped support, movable plate and spring cooperate with each other to form a buffer layer on the lower surface of the photovoltaic panel. When the airflow suddenly hits the lower surface of the photovoltaic panel, the buffer layer cushions the instantaneous impact force and reduces the negative impact caused by the instantaneous impact force. The first wind-resistant member is designed so that when air flows through the vent, the vertical cross-sectional area of ​​the vent gradually decreases, and the air velocity inside the vent increases. According to the Bernoulli effect, the air velocity increases and the pressure decreases. Under the condition that the atmospheric pressure remains unchanged, the first wind-resistant member and the photovoltaic panel are both subjected to downward pressure due to the pressure difference, thereby increasing the wind resistance. The second wind-proof part and the Tesla valve group cooperate with each other, so that when the airflow passes through the space between the metal tile and the second wind-proof part, part of the airflow enters the valve from the air outlet of the Tesla valve. Due to the characteristics of the Tesla valve, the airflow entering from the air outlet will weaken the component consumption, thereby reducing the negative impact caused by the airflow.

[0018] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0020] When used herein, the singular forms "a", "an", and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.

[0021] Example 1 See also Figure 1 and Figure 5 , a photovoltaic roofing system, comprising: a metal tile 1 and a wind-resistant component; The metal tile 1 includes a dovetail groove 12 provided on its upper surface, a clamping piece extending to the upper side of the dovetail groove 12 is provided inside the dovetail groove 12 by screws, and a photovoltaic panel 4 is provided between the clamping piece and the metal tile 1; The metal tile 1 includes a W-shaped tile body 11, a dovetail groove 12 is provided at the symmetry line of the upper surface of the W-shaped tile body 11, and a connecting piece 13 is provided on the upper surface of both ends of the W-shaped tile body 11. The connecting piece 13 is a C-shaped connecting piece. The opening direction of the two connecting pieces 13 is consistent and the sizes are different. The larger connecting piece 13 can be installed outside the smaller connecting piece 13 to connect two adjacent metal tiles 1. like Figure 6 As shown, the clamping member includes a bottom plate 3 arranged inside the dovetail groove 12, a clamping workpiece 2 is arranged above the metal tile 1, and the clamping workpiece 2 is an inverted "X"-shaped workpiece. The top of the clamping workpiece 2 is provided with screws that pass through the clamping workpiece 2 and the dovetail groove 12 from top to bottom. The screws are threadedly connected to the bottom plate 3, and the upper surface of the photovoltaic panel 4 is tightly fitted with the lower surface of the side plate of the clamping workpiece 2; like Figure 2-Figure 4 As shown, the wind-resistant component is arranged between the metal tile 1 and the photovoltaic panel 4, and the wind-resistant component includes an I-shaped support 5 arranged between the clamping workpiece 2 and the metal tile 1, and the I-shaped support 5 includes a hollow cylinder and two limit plates, a hollow cylinder is provided between the two limit plates, and the hollow cylinder is sleeved on the outside of the screw, and a movable plate 6 sleeved on the outside of the hollow cylinder is provided below the photovoltaic panel 4, and a spring 7 is provided between the movable plate 6 and the upper limit plate, and the movable plate 6 is in a separated state from the photovoltaic panel 4 and is in contact with the upper surface of the limit plate below; Based on the above, the dovetail groove 12 is provided so that the bottom plate 3 can be placed therein, and the clamping workpiece 2 is connected to the bottom plate 3 under the action of the screw, thereby achieving the effect of connecting the clamping workpiece 2 to the metal tile 1. Compared with the traditional connection method, this method abandons the metal track, so that the distance between the metal tile 1 and the photovoltaic panel 4 is reduced, thereby reducing the possibility of airflow acting on the lower surface of the photovoltaic panel 4; The photovoltaic panel 4 is blown up because the fast airflow generated by strong winds acts on the photovoltaic panel 4, providing an upward lift to the photovoltaic panel 4. The position where this lift acts is mostly the lower surface of the photovoltaic panel 4. Therefore, by setting the movable plate 6, the airflow is allowed to contact the movable plate 6 first. At the moment when the airflow suddenly contacts the movable plate 6, the movable plate 6 moves upward and compresses the spring 7, reducing the negative impact caused by the instantaneous impact of the airflow. That is, this method avoids direct contact between the airflow and the photovoltaic panel 4 and buffers the instantaneous impact force, thereby reducing the damage caused by the instantaneous impact, thereby increasing the wind resistance.

[0022] Buffered wind-resistant installation Metal tile 1 laying: Arrange the W-shaped tiles 11 in sequence and secure them together with the C-shaped connectors 13. The overlap length of adjacent tiles is 50 mm, and silicone sealant is applied to the joints. Photovoltaic panel 4 fixed: Insert the bottom plate 3 into the dovetail groove 12 and place the photovoltaic panel 4 on the upper surface of the metal tile to cover the bottom plate position; Install the clamping workpiece 2 so that the lower surface of the side plate presses against the photovoltaic panel. Pass the M6 ​​screws through the top plate of the clamping workpiece 2 and connect the photovoltaic panel and bottom plate with threads. The torque is controlled at 8-10N·m. Wind-resistant component installation: Slide the I-shaped support 5 onto the outside of the screws, and place the limit plates on the lower surface of the photovoltaic panel and the upper surface of the metal tile respectively; Install the movable plate 6 and the spring 7, ensuring that the movable plate 6 can slide freely and the spring is in a pre-compressed state.

[0023] Example 2 like Figures 8-10 As shown, based on the first embodiment, the wind-resistant assembly is replaced, and the wind-resistant assembly includes a first wind-resistant member 8, and the first wind-resistant member 8 includes a first top plate 81 located between the clamping workpiece 2 and the metal tile 1. The photovoltaic panel 4 is arranged between the side plate of the clamping workpiece 2 and the first top plate 81. At least four first positioning holes 82 are provided at the edge of the first top plate 81, and the screws pass through the first positioning holes 82; At least two first stabilizing members 83 are provided on the upper surface of the first top plate 81. The two first stabilizing members 83 are respectively provided on both sides of the photovoltaic panel 4. The first stabilizing members 83 are stepped plates consisting of a horizontal plate and an L-shaped plate. The top of the L-shaped top plate is provided with a horizontal plate. The lower surface of the horizontal plate contacts the upper surface of the photovoltaic panel 4, and the side surface of the photovoltaic panel 4 contacts the vertical surface of the L-shaped plate. The lower surface of the first top plate 81 is provided with a rectangular block 84 in contact with the upper surface of the W-shaped tile body 11. Ventilation holes 85 are provided inside the rectangular block 84 along the length of the dovetail groove 12. The vertical cross-sectional area of ​​the ventilation holes 85 gradually decreases along the length of the dovetail groove 12. Based on the above, when the air flow flows through the ventilation hole 85, the vertical cross-sectional area gradually decreases. Under the action of the Venturi effect and the Bernoulli effect, the air flow velocity increases and the air pressure decreases. At this time, the lower surface of the rectangular block 84 is tightly fitted with the upper surface of the W-shaped tile body 11, and the upper surface of the first top plate 81 is also in contact with the lower surface of the photovoltaic panel 4. Therefore, the lower surface of the rectangular block 84 and the upper surface of the first top plate 81 are not affected by the pressure of atmospheric pressure. After the air pressure inside the ventilation hole 85 is reduced, a pressure difference is formed with the atmosphere. Under the action of the first stabilizing member 83 and the downward pressure difference, the photovoltaic panel 4, the first wind-resistant member 8 and the metal tile 1 are more closely fitted, thereby increasing the wind resistance.

[0024] Air pressure difference wind-resistant installation Assembly of the first wind-resistant component 8: A first top plate 81 is placed between the clamped workpiece 2 and the metal tile 1, and screws are passed through the first positioning holes 82 to connect with the bottom plate 3; Attach the first stabilizing member 83 to the side of the photovoltaic panel 4 through the vertical surface of the L-shaped plate, leaving a 0.5mm gap between the lower surface of the horizontal plate and the upper surface of the photovoltaic panel 4; The first wind-resistant member 8 is installed along the roof tilting downward, with the side of the ventilation hole 85 with a larger vertical cross-sectional area facing upward, and the side with a smaller vertical cross-sectional area facing upward; Airflow characteristics verification: Using CFD simulation, when the wind speed is 25m / s (level 10 wind), the flow rate at the ventilation hole outlet reaches 50m / s, the air pressure on the lower surface of the photovoltaic panel decreases by about 400Pa, and the wind resistance is improved by 30%.

[0025] Example 3 like Figure 12-16As shown; on the basis of Example 1, the wind-resistant component is replaced, and the wind-resistant component includes a second wind-resistant part 9, and the second wind-resistant part 9 includes a second top plate 91 located between the clamping workpiece 2 and the metal tile 1, and the photovoltaic panel 4 is arranged between the side plate of the clamping workpiece 2 and the second top plate 91, and at least four second positioning holes 92 are provided at the edge of the second top plate 91, and the screws pass through the second positioning holes 92, and at least two second fixing members 93 are provided on the upper surface of the second top plate 91, and the two second fixing members 93 are respectively arranged on both sides of the photovoltaic panel 4, and the second fixing member 93 is composed of a horizontal plate and an L-shaped The L-shaped top plate is composed of a stepped plate, a horizontal plate is provided on the top of the L-shaped top plate, the lower surface of the horizontal plate is in contact with the upper surface of the photovoltaic panel 4, and the side of the photovoltaic panel 4 is in contact with the vertical surface of the L-shaped plate, and the lower surface of the second top plate 91 is provided with at least one windshield block 96 and at least one group of vertical limit members 94, a group of two vertical limit members 94 are symmetrically distributed, and a placement plate 95 is provided between the two vertical limit members 94, the height of the placement plate 95 toward the windshield block 96 is greater than the height of the side away from the windshield block 96, and the lower surface away from the windshield block 96 is provided with an open groove 97; like Figure 17 and Figure 18 As shown, a Tesla valve assembly 10 is provided between the placement plate 95 and the second top plate 91. The Tesla valve assembly 10 includes a first plate 101, a second plate 102, a third plate 103 and a top cover plate 104 arranged in sequence from top to bottom. The lower surfaces of the first plate 101, the second plate 102 and the third plate 103 are all provided with a Tesla flow channel 105. The lower surface of the top cover plate 104 is provided with a threaded column 106 that passes through the opening groove 97. The outer sleeve of the threaded column 106 A nut is provided that fits tightly with the lower surface of the placement plate 95. The first plate 101, the second plate 102, the third plate 103 and the top cover plate 104 are all provided with an inclined surface 107 on the side away from the windshield block 96. The four inclined surfaces 107 form a complete inclined surface. The air outlet of the Tesla flow channel 105 is provided on the side away from the windshield block 96, and the air inlet is provided on the side facing the windshield block 96. There is a gap between the windshield block 96 and the placement plate 95. Based on the above, the setting of the second wind-resistant component 9 enables the Tesla valve group 10 to be installed between the metal tile 1 and the photovoltaic panel 4. When the airflow flows through the vertical limit components 94, part of the airflow enters the interior of the Tesla flow channel 105 from the air outlet of the Tesla valve. This part of the airflow is gradually consumed as it flows along the Tesla flow channel 105, thereby reducing the negative impact caused by the airflow and increasing the wind resistance.

[0026] Example 3: Tesla valve wind-resistant installation Tesla valve group 10 integration: The first plate 101, the second plate 102, and the third plate 103 are stacked in sequence with the flow channels in the same direction, and fixed to the placement plate 95 via the threaded studs of the top cover 104; Adjust the gap between the windshield block 96 and the placement plate to 10 mm to ensure that the airflow can enter the flow channel through the gap; The two ends of the Tesla valve are convenient for airflow to enter at one end. The airflow velocity is enhanced and then discharged from the other end. The air intake end is the air inlet, and the opposite end is the air outlet. After the airflow enters from the air outlet, the airflow will gradually be consumed. When the Tesla valve assembly 10 is installed, the side of the Tesla valve assembly 10 that is away from the windshield block 96 faces downward along the inclined roof, and the windshield block 96 faces upward along the inclined roof; Wind resistance test: In the wind tunnel test, when the wind speed was 30m / s (level 11 wind), the airflow pressure through the Tesla valve group dropped from 500Pa to 90Pa, and the uplift force of the photovoltaic panel was reduced by 82%.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
