Description

Technical Field

[0001] This invention relates to the field of building-integrated photovoltaics (BIPV) technology, specifically a building-integrated photovoltaic roof. Background Technology

[0002] With the increasing severity of the global energy crisis and environmental problems, Building Integrated Photovoltaics (BIPV) technology has become one of the key technologies for promoting green energy development because it combines building roofs with photovoltaic power generation functions. Traditional solar photovoltaic power generation systems are usually installed on the ground or on special brackets. This not only occupies valuable land resources, but may also lead to visual disharmony. In contrast, BIPV technology cleverly integrates photovoltaic modules with the building roof, making full use of the building roof space and making the building appearance more beautiful and harmonious. Specifically, BIPV technology converts solar energy into electrical energy by installing photovoltaic modules on the building roof, which is then directly supplied to the building or connected to the grid. The core of this technology lies in the perfect combination of photovoltaic modules and building materials, so that the photovoltaic modules not only have the function of power generation, but also have building functions such as waterproofing and heat insulation.

[0003] However, traditional building-integrated photovoltaics (BIPV) technology faces several challenges in practical applications. First, it typically uses fixed-angle installation of photovoltaic modules, which cannot automatically adjust the angle according to changes in the sun's altitude and azimuth, resulting in low power generation efficiency. Furthermore, due to the fixed angle, the amount of solar radiation received by the modules varies significantly across different seasons and time periods, affecting the overall system's power generation performance. Second, in severe weather conditions such as strong winds, the limitations of its structural design and fixing methods make it easy for photovoltaic modules to be overturned or fall, threatening building and personal safety. This can not only damage the photovoltaic system but also cause serious economic losses and safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a building-integrated photovoltaic (BIPV) roof to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A building-integrated photovoltaic (BIPV) roof includes several photovoltaic (BIPV) building frames installed on the roof of a building. Photovoltaic panels are laid on top of each photovoltaic building frame. Each photovoltaic building frame includes a support unit, which includes a rectangular frame. An electric telescopic rod is fixedly connected to each of the four corners of the bottom surface of the rectangular frame. A counterweight is fixedly connected to the bottom end of each of the four electric telescopic rods. The bottom surfaces of the four counterweights are in contact with the roof of the building. Two square slots are symmetrically formed on the top surface of the rectangular frame. An adjustment frame is slidably connected in the two square slots. Four rotating blocks are fixedly connected to each of the four corners of the top surface of the rectangular frame.

[0007] Furthermore, the adjusting frame includes two square rods, the outer walls of which are slidably connected to the inner walls of two square grooves respectively. An electric telescopic rod II is fixedly connected to the bottom end of each of the two square rods, and a counterweight II is fixedly connected to the bottom end of each of the two electric telescopic rod IIs. A connecting block I is fixedly connected to the side wall of each of the two square rods on the same side, and a connecting block II is fixedly connected to the other side wall of each of the two square rods on the same side. A round rod II is fixedly connected between each of the two connecting blocks II and the two connecting blocks I. A telescopic frame is rotatably connected to the outer wall of each of the two round rod IIs, and a connecting block III is fixedly connected to the top end of each of the two square rods.

[0008] Furthermore, a round rod is fixedly connected between the two connecting blocks three, and two fixed frames are rotatably connected to the outer wall of the round rod one. The two fixed frames are symmetrical about the round rod one as the axis, and the photovoltaic panel is laid on the top surface of the fixed frames.

[0009] Furthermore, both telescopic frames include an upper frame, with the adjacent ends of the two upper frames rotatably connected to two round rods, and two symmetrical sliding grooves opened on the distant ends of the two upper frames. Sliding rods are slidably connected in the two sliding grooves, and the other ends of the two sliding rods are fixedly connected to a lower frame. The outer walls of the two lower frames are rotatably connected to four rotating blocks.

[0010] Furthermore, the inner walls of both upper frames are fixedly connected to rotating seats one, and the interiors of both rotating seats one are rotatably connected to electric telescopic rods three. The other ends of both electric telescopic rods three are rotatably connected to rotating seats two, and the top surfaces of the two rotating seats two are fixedly connected to the bottom surfaces of the two fixed frames respectively.

[0011] Furthermore, each of the two mutually distant sidewalls of the lower frame is symmetrically fixed with two fixing units, and each of the four fixing units includes an inverted plate. The end side of the inverted plate is fixedly connected to the sidewall of the lower frame. A compression airbag is fixedly connected to the inner sidewall of the inverted plate. An airbag box is inserted and fixed to the top surface of the inverted plate. A cavity is opened inside the airbag box. A telescopic airbag is fixedly connected to the top surface of the cavity. A connecting rod is fixedly connected to the bottom surface of the telescopic airbag. The telescopic airbag and the compression airbag are connected through an air tube.

[0012] Preferably, the top surface of the lower frame corresponding to the location of the plug rod has a plug hole.

[0013] Preferably, the top surface of the fixing frame corresponding to the position of the plug rod is provided with a plug groove.

[0014] Furthermore, the rectangular frame located below the fixed unit has two side walls fixedly connected to water collection units, each water collection unit including a water collection trough.

The bottom surface of each water collection trough is provided with a water inlet. A folding water bucket is provided below each water collection trough. The top surface of the folding water bucket is provided with a water inlet corresponding to the water inlet. The top surface of the folding water bucket is symmetrically fixed with two handles.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 In this embodiment of the invention, a building-integrated photovoltaic (BIPV) roof includes several photovoltaic building frames 100 installed on the roof of a building. Photovoltaic panels 200 are laid on top of each photovoltaic building frame 100. Each photovoltaic building frame 100 includes a support unit 110, which includes a rectangular frame 111. Electric telescopic rods 112 are fixedly connected to the four corners of the bottom surface of the rectangular frame 111. Counterweights 113 are fixedly connected to the bottom ends of the four electric telescopic rods 112. The bottom surfaces of the four counterweights 113 are in contact with the roof of the building. Two square grooves 114 are symmetrically opened on the top surface of the rectangular frame 111. Adjustment frames 130 are slidably connected in the two square grooves 114. Four rotating blocks 115 are fixedly connected to the four corners of the top surface of the rectangular frame 111.

[0032] Specifically, by setting up several photovoltaic building frames 100, it is easy to transport and install, can be adapted to the paving of roofs of different areas, and is easy to maintain. The counterweight 113 adds weight to the entire photovoltaic building frame 100 to ensure overall stability and prevent tipping. By controlling the extension or retraction of the electric telescopic rod 112, the height of the entire photovoltaic building frame 100 can be changed.

[0033] Example 1

[0034] like Figure 3-6As shown, in this embodiment, the adjusting frame 130 includes two square rods 131. The outer walls of the two square rods 131 are slidably connected to the inner walls of two square grooves 114, respectively. A second electric telescopic rod 134 is fixedly connected to the bottom end of each of the two square rods 131. A second counterweight 135 is fixedly connected to the bottom end of each of the two electric telescopic rods 134. A first connecting block 132 is fixedly connected to the side wall of each of the two square rods 131 on the same side. A second connecting block 133 is fixedly connected to the other side wall of each of the two square rods 131 on the same side. A second round rod 138 is fixedly connected between the two second connecting blocks 133 and the two first connecting blocks 132. A telescopic frame 140 is rotatably connected to the outer wall of each of the two round rods 138. A third connecting block 136 is fixedly connected to the top end of each of the two square rods 131. A first round rod 137 is fixedly connected between the two third connecting blocks 136. Two fixed frames 150 are rotatably connected to the outer wall of the first round rod 137. Two fixed frames 150 are symmetrical about a circular rod 137. A photovoltaic panel 200 is laid on the top surface of the fixed frame 150. Both telescopic frames 140 include an upper frame 141. The two upper frames 141 are rotatably connected to two circular rods 138 at their close ends. Two sliding grooves are symmetrically opened on the two upper frames 141 at their far ends. Sliding rods 142 are slidably connected in the two sliding grooves. The other ends of the two sliding rods 142 are fixedly connected to a lower frame 143. The outer walls of the two lower frames 143 are rotatably connected to four rotating blocks 115. Rotating seats 144 are fixedly connected to the inner walls of the two upper frames 141. Electric telescopic rods 145 are rotatably connected inside the two rotating seats 144. Rotating seats 151 are rotatably connected to the other ends of the two electric telescopic rods 145. The top surfaces of the two rotating seats 151 are fixedly connected to the bottom surfaces of the two fixed frames 150.

[0035] In this embodiment, the photovoltaic panel 200 is laid on the surface of two fixed frames 150. By controlling the extension or retraction of the electric telescopic rod 145, the angle between the two fixed frames 150 can be changed, allowing the photovoltaic panel 200 to automatically adjust its angle according to the sun's position, increasing the time the photovoltaic panel 200 is exposed to sunlight and increasing the conversion efficiency. When encountering strong winds, the extended fixed frames 150 are easily blown over and fall, causing accidents. When there is severe weather such as strong winds, the electric telescopic rod 145 is driven to retract, causing the two fixed frames 150 to extend towards their corresponding telescopic frames. 140 is attached until the fixed frame 150 and the upper frame 141 are in contact. The retracted electric telescopic rod 145 will also be stored in the inner frame of the upper frame 141, reducing the angle between the fixed frame 150 and the upper frame 141. This prevents strong winds from blowing through and overturning the frame. At the same time, the electric telescopic rod 134 can be controlled to move the square rod 131 downward, thereby moving the slide rod 142 into the slide groove in the upper frame 141. This increases the angle between the two fixed frames 150. At the same time, the electric telescopic rod 112 can be controlled to retract, reducing the overall height and the stress area.

[0036] like Figure 2 and Figure 8 As shown, in this embodiment, two fixing units 160 are symmetrically fixed to the sidewalls of the two lower frames 143 that are far apart from each other. Each of the four fixing units 160 includes a C-shaped plate 161. The end side of the C-shaped plate 161 is fixedly connected to the sidewall of the lower frame 143. A compression airbag 163 is fixedly connected to the inner sidewall of the C-shaped plate 161. An airbag box 162 is inserted and fixed to the top surface of the C-shaped plate 161. A cavity is opened inside the airbag box 162. A telescopic airbag 164 is fixedly connected to the top surface of the cavity. A plug-in rod 165 is fixedly connected to the bottom surface of the telescopic airbag 164. The telescopic airbag 164 and the compression airbag 163 are connected through an air pipe 166. A plug-in hole 146 is opened on the top surface of the lower frame 143 corresponding to the position of the plug-in rod 165. A plug-in groove 152 is opened on the top surface of the fixing frame 150 corresponding to the position of the plug-in rod 165.

[0037] In specific implementation, the size of the fixed frame 150 is smaller than the unfolded size of the telescopic frame 140. When the electric telescopic rod 145 retracts, causing the fixed frame 150 to rest against the surface of the upper frame 141, the electric telescopic rod 134 retracts. Due to the rotatable connection between the lower frame 143 and the rotating block 115, when the electric telescopic rod 134 drives the square rod 131 to retract, the sliding rod 142 will move into the groove inside the upper frame 141, causing the lower frame 143 to approach the upper frame 141. This causes the side wall of the fixed frame 150 to gradually approach the compression airbag 163, and compress the compression airbag 163 during the movement. While the fixed frame 150 compresses the compression airbag 163, the gas inside the compression airbag 163 is transferred into the telescopic airbag 164 through the air pipe 166. The inflated telescopic airbag 164 will then press the insertion rod 1... Pushing 65 outwards causes the downward-extending insertion rod 165 to pass through the insertion slot 152 and insert into the insertion hole 146, making the fixed frame 150 and the telescopic frame 140 fit more firmly and enhancing their stability in severe windy weather. When the weather returns to normal, the electric telescopic rod 134 is driven to extend, causing the slide rod 142 to extend outwards from the slide groove. That is, the lower frame 143, along with the C-shaped plate 161, gradually moves away from the fixed frame 150, so that the fixed frame 150 no longer compresses the compression airbag 163. At this time, the gas in the telescopic airbag 164 will return to the compression airbag 163 through the air tube 166, causing the insertion rod 165 to retract into the airbag box 162 and no longer insert into the insertion hole 146 and the insertion slot 152. At this time, the electric telescopic rod 145 can be controlled to extend or retract to change the angle of the two fixed frames 150.

[0038] Example 2

[0039] like Figure 2 and Figure 7 As shown, in this embodiment, two side walls of the rectangular frame 111 located below the fixed unit 160 are fixedly connected to water collection units 120. Each water collection unit 120 includes a water collection trough 121. The side walls of the two water collection troughs 121 are fixedly connected to the two side walls of the rectangular frame 111, respectively. The bottom surface of each water collection trough 121 is provided with a water inlet 122. A folding water bucket 123 is provided below each water collection trough 121. The top surface of the folding water bucket 123 is provided with a water inlet 124 at a position corresponding to the water inlet 122. Two handles 125 are symmetrically fixed on the top surface of the folding water bucket 123. The two handles 125 and the bottom surface of the water collection trough 121 are connected by steel wire ropes 126. The outer wall of the folding water bucket 123 is connected to a drain pipe 127.

[0040] In practical implementation, with the arrival of windy weather, rain is usually also present. By fixing water collection troughs 121 to both side walls of the rectangular frame 111, the rainwater falling on the photovoltaic panel 200 is ultimately collected by the water collection troughs 121 and flows into the folding water bucket 123 through the water inlet 122. The folding water bucket 123 is relatively lighter than a regular water bucket when empty, not excessively increasing the load on the support unit 110. When the folding water bucket 123 contains water, the suspended folding water bucket 123 unfolds under the weight of the water and falls downwards, controlled by electricity... The retraction of the telescopic rod 112 allows the bottom of the folding water bucket 123 filled with water to contact the rooftop, preventing the support unit 110 from being overloaded due to the folding water bucket 123 being constantly suspended. In strong winds, the electric telescopic rod 112 can be extended to lift the folding water bucket 123 off the ground. The two folding water buckets 123 filled with water will increase the downward gravity on the photovoltaic building frame 100, enhancing the stability of the photovoltaic building frame 100 in severe weather. Rainwater stored in the folding water buckets 123 can be discharged through the drain pipe 127 for watering plants, saving water resources.

[0041] In this invention, for areas where heavy rainfall is not likely to occur, the size of the fixed frame 150 can be set to be larger than the unfolded size of the telescopic frame 140. In this case, retracting the electric telescopic rod 145 will cause the fixed frame 150 to directly abut against the edge of the roof. When it rains, the rainwater will flow from the edge of the roof into the sewer along the surface of the fixed frame 150.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
