Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic roofs, in particular to a photovoltaic roof. Background Art

[0002] A photovoltaic roof is a rooftop solar panel installed on the roof of a house, which uses solar photovoltaic technology to generate electricity in order to achieve energy conservation and emission reduction goals. Through rooftop photovoltaic power generation, energy self-sufficiency can be achieved and dependence on external energy can be reduced, which will help promote sustainable development in rural areas and improve energy security.

[0003] A patent with the publication number CN115522694A discloses a photovoltaic roof and a construction method of the photovoltaic roof, which forms a first waterproof layer on the roof by spreading the waterproof panel over the entire roof, and then installing a combined connector on the connecting edge, and detachably connecting the supporting member on the combined connector, and overlapping the photovoltaic panel on the supporting member, and then using a sealing buckle plate to seal and fix the photovoltaic panel, and then using a photovoltaic roof ridge cover to seal the gap between the two groups of photovoltaic panels on both sides of the ridge, forming a second waterproof layer on the roof, thereby improving the waterproof effect of the entire photovoltaic roof. In the process of connection, the structure of the waterproof panel itself is not destroyed, so that the waterproof panel remains intact and unbroken, thereby reducing the possibility of the connection of the waterproof panel being eroded by wind and rain and forming a leak point.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The photovoltaic roof described in the present invention is located in coastal cities or in households with high floors. After photovoltaic panels are installed, typhoons may occur in coastal cities, which may blow down the photovoltaic panels. There are certain safety hazards if photovoltaic panels installed by residents in high-rise buildings fall. By installing the top plate on the roof, the rectangular frame drives the photovoltaic panel to be tilted on the roof. When the rectangular frame is loose, it drives the first cylindrical rod to rotate, so that the parachute will open when the starting rope is pulled. After the parachute is opened, the wind continues to blow the parachute, and the parachute is subject to greater resistance. The parachute pulls one side of the rectangular frame through the pull rope to make the rectangular frame rotate downward to prevent the rectangular frame from falling, thereby protecting property safety and reducing safety hazards.

[0019] 2.

The angle between the rectangular frame and the top plate can be adjusted according to different seasons. When adjusting the angle between the rectangular frame and the top plate, the bolts between the first waist-shaped bar and the second waist-shaped bar are driven to loosen, so that the first waist-shaped bar and the second waist-shaped bar can rotate, so that the second waist-shaped bar always keeps a vertical state. After adjusting the angle between the rectangular frame and the top plate, the bolts are driven to rotate to fix the first waist-shaped bar and the second waist-shaped bar together. When the rectangular frame is loose, it will drive the first rectangular plate and the top plate to rotate. At this time, the first rectangular plate slides through the first cylindrical bar through the first circular plate, and the first circular plate drives the second waist-shaped bar to rotate through the first waist-shaped bar. When the second waist-shaped bar is tilted when viewed from the side, it means that the rectangular frame may be loose. Subsequently, during maintenance, it is possible to check whether the angle of the photovoltaic panel is loose without climbing onto the roof. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] Embodiment 1

[0031] like Figure 1-Figure 6 As shown, a photovoltaic roof described in an embodiment of the present invention includes a top plate 1, a third fixed block 13 is fixedly connected to one side of the upper end of the top plate 1, the third fixed block 13 is rotatably connected to a rectangular frame 11 through a first cylindrical rod 131, a plurality of photovoltaic panels 111 are installed in the middle of the rectangular frame 11, a windproof device is provided on one side of the top plate 1, the windproof device includes a parachute 2 installed at both ends of one side of the top plate 1, a starting rope 21 is provided on one side of the parachute 2, the starting rope 21 is connected to the first cylindrical rod 131, and the pull rope 22 of the parachute 2 passes through the top plate 1 and is fixed to one side of the rectangular frame 11 respectively.

[0032] Specifically, the shape of the top plate 1 can be selected according to specific circumstances. The top plate 1 can be set in the shape of a horizontal roof or a sloping roof, or it can be covered on the original roof of the building by pouring and riveting. The top plate 1 shown in the attached figure is a flat roof. In order to enable the photovoltaic panel 111 to receive sunlight to the maximum extent, the photovoltaic panel 111 is generally tilted. The tilt angle of the photovoltaic panel 111 is usually selected to be the local latitude or the local latitude plus a few degrees. This is because the sun has different incident angles at different times of the year. Selecting a suitable tilt angle can ensure that the photovoltaic panel 111 is perpendicular to the sunlight most of the time, thereby maximizing power generation. Since the photovoltaic panel 111 is tilted on the roof, the angle between the photovoltaic panel 111 and the roof will generate greater resistance, which will increase the risk of the photovoltaic panel 111 falling. When using this photovoltaic roof, the top plate 1 is installed on the top of the original building, and then the rectangular frame 11 is driven to drive the photovoltaic panel 111 to rotate on one side of the top plate 1. When the rectangular frame 11 rotates, it drives the first circular The column 131 rotates in the middle of the third fixed block 13 to adjust the photovoltaic panel 111 to a suitable angle, and then the rectangular frame 11 can be fixed with bolts. When encountering severe weather such as strong winds or storms, the angle between the photovoltaic panel 111 and the top plate 1 is subject to greater wind resistance, which may cause the rectangular frame 11 to loosen. When the rectangular frame 11 rotates, it will drive the first cylindrical rod 131 to rotate, and at the same time drive the starting rope 21 to be wrapped around the outside of the first cylindrical rod 131. When the starting rope 21 is pulled, the parachute 2 will be opened. After the parachute 2 is opened, the wind continues to blow the parachute 2. At this time, the parachute 2 is subject to greater resistance. The parachute 2 pulls one side of the rectangular frame 11 through the pull rope 22 to make the rectangular frame 11 rotate downward to prevent the rectangular frame 11 from falling, thereby protecting property safety and reducing safety hazards.

[0033] It should be noted that the roof is preferably but not limited to being installed on the top of a high-rise building for use, and a height expansion structure can also be installed at the bottom end of the top plate 1 to allow the parachute 2 to have more operating space and deployment time.

[0034] like Figure 3-Figure 4 As shown, a first rectangular plate 112 is arranged in parallel on one side of the rectangular frame 11, and a first rectangular bar 113 is fixedly connected to both sides of the rectangular frame 11 and the first rectangular plate 112 respectively, and a second fixing block 115 is fixedly connected to both sides of the first rectangular bar 113 on one side, and the second fixing block 115 is fixedly connected to the first cylindrical rod 131, and the second fixing block 115 can rotate in the middle of the third fixing block 13, and first circular holes 12 are respectively provided on both sides of the top plate 1, and second cylinders 15 are respectively fixedly connected to positions corresponding to the first circular holes 12 on one side of the top plate 1, and one side of the second cylinder 15 is fixedly connected to the parachute 2, and the pull rope 22 passes through the second cylinder 15 and the first circular hole 12 respectively and is fixedly connected to one side of the rectangular frame 11.

[0035] Specifically, the photovoltaic panel 111 is installed flat in the middle of the rectangular frame 11, and a first rectangular plate 112 is arranged on one side of the rectangular frame 11. The wiring harness is placed between the first rectangular plate 112 and the rectangular frame 11. When the rectangular frame 11 rotates, the first cylindrical rod 131 on one side of the rectangular frame 11 is driven to rotate in the middle of the third fixed block 13 through the second fixed block 115, thereby pulling the starting rope 21 to open the parachute 2.

[0036] like Figure 5 As shown, a rectangular groove 16 is provided at the upper end of the top plate 1, and an angle adjustment device is provided between the inside of the rectangular groove 16 and the first rectangular plate 112. The angle adjustment device includes a rectangular slider 162 slidably arranged inside the rectangular groove 16, and both ends of the rectangular slider 162 are rotatably connected to the first rectangular plate 112 through connecting rods 161.

[0037] Specifically, the altitude and azimuth of the sun will change significantly in different seasons. The altitude of the sun is higher in summer and lower in winter. This means that in different seasons, the photovoltaic panel 111 needs different installation angles to maximize the reception of solar radiation. When using the photovoltaic roof, the rectangular slider 162 is driven to slide in the rectangular groove 16, and the connecting rod 161 is used to drive the rectangular frame 11 and the top plate 1 to rotate, thereby adjusting the angle between the rectangular frame 11 and the top plate 1. By reasonably adjusting the installation angle of the photovoltaic panel 111, the absorption of sunlight energy can be maximized and the efficiency of photovoltaic power generation can be improved.

[0038] like Figure 5 As shown, a plurality of drainage holes 163 are provided at the lower end of the rectangular groove 16, and the drainage holes 163 are arranged to be inclined downward.

[0039] Specifically, since the photovoltaic panel 111 is installed on the roof for a long time, water may accumulate on the top of the top plate 1. A plurality of downwardly inclined drainage holes 163 are provided on one side of the rectangular groove 16 to facilitate drainage and prevent water accumulation.

[0040] like Figure 4 As shown, the first cylinder 14 is rotatably connected to the outer sides of both ends of the first cylindrical rod 131, the first cylinder 14 is fixedly connected to the end of the starting rope 21, and the middle part of the first cylinder 14 is threadedly connected to a screw rod 141.

[0041] Specifically, when it is necessary to adjust the angle between the rectangular frame 11 and the top plate 1, the screw rod 141 is driven to rotate so that the first cylinder 14 is separated from the first cylindrical rod 131. At this time, the first cylindrical rod 131 can rotate in the middle of the first cylinder 14, and then the rectangular frame 11 is driven to rotate, and the first cylindrical rod 131 is driven to rotate at the same time. When the first cylindrical rod 131 rotates, the first cylinder 14 remains stationary to prevent the starting rope 21 from being pulled. After the angle between the rectangular frame 11 and the top plate 1 is adjusted, the screw rod 141 is driven to rotate so that the screw rod 141 is against the side wall of the first cylindrical rod 131 to fix the first cylinder 14 and the first cylindrical rod 131. When the rectangular frame 11 is rotated by strong wind, the first cylindrical rod 131 drives the first cylinder 14 to rotate and pulls the starting rope 21 to start the parachute 2 and prevent the rectangular frame 11 from falling.

[0042] like Figure 6 As shown, a tightening device is provided on one side of the top plate 1, and the tightening device includes a first L-shaped strip 4 fixedly connected to the position corresponding to the first circular hole 12 on one side of the top plate 1, and a group of second circular plates 41 are rotatably connected to one side of the first L-shaped strip 4, and a group of second circular plates 41 include two parallel second circular plates 41, and two second cylindrical strips 411 are fixedly connected between the two second circular plates 41. The pull rope 22 is located in the middle of the two second cylindrical strips 411, and a second cylindrical rod 42 is commonly fixed between the two groups of second circular plates 41. The first rectangular strip 113 close to one side of the first L-shaped strip 4 is fixedly connected to the first fixed blocks 114 on both sides, and the first cylindrical block 1141 is rotatably connected to the middle of the first fixed block 114, and the pull rope 22 is fixedly connected to the first cylindrical block 1141.

[0043] Specifically, when the angle between the rectangular frame 11 and the top plate 1 is adjusted, the pull rope 22 may become loose. After the pull rope 22 becomes loose, it will shake left and right to generate friction, which will cause wear on the pull rope 22. When the angle between the rectangular frame 11 and the top plate 1 is adjusted, the pull rope 22 is located between the second cylindrical bars 411. The rotation of the second cylindrical bar 411 can wrap the pull rope 22 around the outside of the second cylindrical bar 411. According to the change of the angle between the rectangular frame 11 and the top plate 1, the second circular plate 41 is driven to drive the second cylindrical bar 411 to rotate, so that the pull rope 22 always remains in a straight state to prevent the pull rope 22 from becoming loose.

[0044] like Figure 6 As shown, a second L-shaped strip 43 is fixedly connected to the middle of one side of the top plate 1 , a circular ring 431 is rotatably connected to the middle of the second L-shaped strip 43 via a torsion spring, and a central portion of the circular ring 431 is fixedly connected to the second cylindrical rod 42 .

[0045] Specifically, the ring 431 rotates with the second L-shaped strip 43 through the torsion spring, so that the ring 431 drives the second cylindrical rod 42 to rotate to one side all the time, and the second cylindrical rod 42 drives the second cylindrical strip 411 to rotate to one side all the time through the second circular plate 41, so that the pull rope 22 is always wrapped around the outside of the second cylindrical strip 411, so that the pull rope 22 remains in a straight state. When the angle between the rectangular frame 11 and the top plate 1 is adjusted, the length of the pull rope 22 changes. When the length of the pull rope 22 changes, the second cylindrical rod 42 is driven to rotate through the second circular plate 41, and the second cylindrical rod 42 drives the ring 431 to rotate in the middle of the second L-shaped strip 43. When the angle between the rectangular frame 11 and the top plate 1 is adjusted, the length of the pull rope 22 can be automatically adjusted, and the pull rope 22 is always kept in a straight state.

[0046] like Figure 6 As shown, a rotating wheel 44 is rotatably arranged at a position corresponding to the first L-shaped strip 4 on one side of the top plate 1 .

[0047] Specifically, when the parachute 2 is opened, when one side of the rectangular frame 11 is pulled by the pull rope 22, the pull rope 22 may generate friction with one side of the top plate 1. The pull rope 22 is placed on one side of the rotating wheel 44. When the pull rope 22 is pulled, the rotating wheel 44 is driven to rotate to prevent friction on the pull rope 22.

[0048] Embodiment 2

[0049] like Figure 7 As shown, compared with Example 1, another implementation of the present invention is: arc blocks 3 are fixedly connected to both sides of the upper end of the top plate 1, and a scale line 32 is provided on one side of the arc surface of the arc block 3.

[0050] Specifically, when adjusting the angle between the rectangular frame 11 and the top plate 1 , the angle between the rectangular frame 11 and the top plate 1 can be controlled by observing the scale line 32 provided on one side of the arc block 3 , so that the angle between the rectangular frame 11 and the top plate 1 can be adjusted more accurately.

[0051] like Figure 7 As shown, an arc-shaped hole 31 is provided in the middle of the arc block 3, and two first cylindrical bars 33 are slidably provided in the middle of the arc hole 31. The two first cylindrical bars 33 are respectively located on both sides of the first rectangular plate 112, and one side of the two first cylindrical bars 33 is commonly fixed with a first circular plate 331, and one side of the first circular plate 331 is fixed with a first waist-shaped bar 332. The end of the first waist-shaped bar 332 away from the first circular plate 331 is rotatably connected to the second waist-shaped bar 333 by bolts, and the second waist-shaped bar 333 can rotate on one side of the arc block 3.

[0052] Specifically, when adjusting the angle between the rectangular frame 11 and the top plate 1, the bolts between the first waist-shaped bar 332 and the second waist-shaped bar 333 are driven to loosen, so that the first waist-shaped bar 332 and the second waist-shaped bar 333 can rotate, so that the second waist-shaped bar 333 always keeps a vertical state. After adjusting the angle between the rectangular frame 11 and the top plate 1, the bolts are driven to rotate to fix the first waist-shaped bar 332 and the second waist-shaped bar 333 together. Since the photovoltaic panel 111 is laid on the roof for a long time, the rectangular frame 11 may become loose after a long time of use. When the rectangular frame 11 is loose, it is generally necessary to go to the roof for maintenance, which is troublesome. The first cylindrical bars 33 are arranged on both sides. When the rectangular frame 11 is loose, the rectangular frame 11, the first rectangular plate 112 and the top plate 1 will rotate. At this time, the first rectangular plate 112 drives the first cylindrical bar 33 to slide in the arc hole 31. The first cylindrical bar 33 drives the first waist-shaped bar 332 to rotate through the first circular plate 331. The first waist-shaped bar 332 drives the second waist-shaped bar 333 to rotate. In a normal state, the second waist-shaped bar 333 is in a vertical state. When the second waist-shaped bar 333 is tilted when observed from the side, it means that the rectangular frame 11 may be loose. Subsequently, during maintenance, it is possible to check whether the angle of the photovoltaic panel 111 is loose without climbing onto the roof.

[0053] Working principle: When using the photovoltaic roof, the top plate 1 is installed on the roof, and then the rectangular slider 162 is driven to slide in the rectangular groove 16, and the rectangular frame 11 and the top plate 1 are driven to rotate through the connecting rod 161, so as to adjust the angle between the rectangular frame 11 and the top plate 1;

[0054] When adjusting the angle between the rectangular frame 11 and the top plate 1, the screw rod 141 is driven to rotate, so that the first cylinder 14 is separated from the first cylindrical rod 131. At this time, the first cylindrical rod 131 can rotate in the middle of the first cylinder 14. Then, the rectangular frame 11 is driven to rotate, and the first cylindrical rod 131 is driven to rotate at the same time. When the first cylindrical rod 131 rotates, the first cylinder 14 remains stationary to prevent the starting rope 21 from being pulled. After adjusting the angle between the rectangular frame 11 and the top plate 1, the screw rod 141 is driven to rotate, so that the screw rod 141 is pressed against the side wall of the first cylindrical rod 131, so that the first cylinder 14 and the first cylindrical rod 131 are fixed;

[0055] At the same time, the bolts between the first waist-shaped bar 332 and the second waist-shaped bar 333 are driven to loosen, so that the first waist-shaped bar 332 and the second waist-shaped bar 333 can rotate, so that the second waist-shaped bar 333 always remains in a vertical state. After adjusting the angle between the rectangular frame 11 and the top plate 1, the bolts are driven to rotate to fix the first waist-shaped bar 332 and the second waist-shaped bar 333 together.

[0056] During the adjustment process, since the second cylindrical rod 42 drives the second cylindrical strip 411 to rotate to one side all the time through the second circular plate 41, the drawstring 22 is always wound around the outside of the second cylindrical strip 411, so that the drawstring 22 is kept in a straight state. When the angle between the rectangular frame 11 and the top plate 1 is adjusted, the length of the drawstring 22 changes. When the length of the drawstring 22 changes, the second cylindrical rod 42 is driven to rotate through the second circular plate 41, and the second cylindrical rod 42 drives the ring 431 to rotate in the middle of the second L-shaped strip 43. When the angle between the rectangular frame 11 and the top plate 1 is adjusted, the length of the drawstring 22 can be automatically adjusted, and the drawstring 22 is always kept in a straight state.

[0057] When encountering strong winds, the angle between the photovoltaic panel 111 and the top plate 1 is subject to greater wind resistance, which may cause the rectangular frame 11 to loosen. When the rectangular frame 11 rotates, it will drive the first cylindrical rod 131 to rotate, and the first cylindrical rod 131 will drive the first cylinder 14 to rotate and pull the starting rope 21 to start the parachute 2. The parachute 2 pulls one side of the rectangular frame 11 through the pull rope 22, so that the rectangular frame 11 rotates downward to prevent the rectangular frame 11 from falling.

[0058] By setting the first cylindrical bar 33 on both sides of the first rectangular plate 112, when the rectangular frame 11 is loose, the rectangular frame 11, the first rectangular plate 112 and the top plate 1 will rotate. At this time, the first rectangular plate 112 drives the first cylindrical bar 33 to slide in the arc hole 31, and the first cylindrical bar 33 drives the first waist-shaped bar 332 to rotate through the first circular plate 331, and the first waist-shaped bar 332 drives the second waist-shaped bar 333 to rotate. In a normal state, the second waist-shaped bar 333 is in a vertical state. When the second waist-shaped bar 333 is tilted when observed from the side, it means that the rectangular frame 11 may be loose. Subsequently, during maintenance, it is possible to check whether the angle of the photovoltaic panel 111 is loose without climbing onto the roof.
