Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and more specifically to a photovoltaic module mounting bracket for corrugated steel tile roofs. Background Technology

[0002] With the promotion of photovoltaic power generation technology and the decrease of high-quality flat sites, it has become an important trend to install photovoltaic systems on the large-area corrugated steel roofs of industrial plants and other buildings. Commonly used photovoltaic installations on corrugated steel roofs mainly adopt two methods: clamp fixing or adhesive bonding. However, clamp installation requires drilling holes in the corrugated steel roof to install guide rails. After drilling, the roof waterproofing is damaged, and the roof surface will also be corroded due to drilling. Under the roof adhesive bonding method, the photovoltaic panels and corrugated steel tiles will be damaged during the dismantling process, which is not conducive to recycling.

[0003] Traditional photovoltaic (PV) installations on corrugated steel roofs expose the PV modules directly to the external environment. However, since the PV panels are typically protected by tempered glass, they are vulnerable to damage in extreme weather conditions, especially severe hail and blizzards. The immense impact of falling hail can crack the tempered glass panels, easily causing damage. Meanwhile, the heavy snowfall from blizzards applies continuous lateral pressure, similarly threatening the integrity of the panels. This not only affects power generation but also increases maintenance costs and shortens the lifespan of the PV panels.

[0004] Therefore, it is necessary to study a photovoltaic module mounting bracket for corrugated steel tile roofs. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a photovoltaic module mounting bracket for corrugated steel tile roofs, which effectively solves the problem that existing photovoltaic mounting brackets lack effective protection under extreme weather conditions, making them prone to damage to photovoltaic modules.

[0006] To achieve the above objectives, the technical solution adopted by this invention is: a photovoltaic module mounting bracket for a color steel tile roof, comprising a base, a protective component and at least one set of folding components on the base, each set of folding components comprising a folding plate, a drive seat and a diagonal brace, the drive seat being disposed on the base and capable of reciprocating along the base, the front end of the folding plate being hinged to the base, and its hinge axis being capable of reciprocating along the base, a photovoltaic panel being mounted on the folding plate, and the diagonal brace being obliquely hinged between the folding plate and the drive seat, causing the drive seat to drive the folding plate to swing and fold up or retract around the hinge point; The protective assembly includes a guide rail, a protective cover, a guide rod, a traction rope, and a winding reel. The guide rod is fixed vertically to the base, and a guide sleeve is slidably fitted onto the guide rod. The guide rail is located above the folding plate, and both the guide rail and the guide sleeve have their side walls hinged to the guide rail. The front end of the guide rail is hinged to the base. The protective cover is located above the folding plate, and its left and right sides extend into the guide rail and are fixedly connected to the traction rope inside. The output end of the traction rope is wound around the winding reel, which is connected to the hinge shaft of the folding plate via a transmission assembly for unfolding or retracting the protective cover.

[0007] Furthermore, the inner cavity of the guide rail is hollow, and its front end is an arc-shaped transition section. A second guide groove is opened on the base corresponding to the transition section. A slide block is fitted into the second guide groove, and the front end of the slide block is hinged to the transition section of the guide rail.

[0008] Furthermore, the base has a track groove along the front-to-back direction, and a screw is rotatably installed in the track groove. The drive seat is threadedly connected to the screw and adapted to be installed in the track groove; one end of the screw is connected to a folding motor.

[0009] Furthermore, the transmission assembly includes a connecting rod, a rack, a slide rail, and a gear. The two ends of the hinge shaft of the folding plate extend to the outer side of the hinge seat and are rotatably fitted with a connecting rod. The rear side of the connecting rod is fixedly connected to a rack. The slide rail is fixed to the base in a horizontal direction, and the rack is adapted to slide on the slide rail. The winding wheel is rotatably mounted on the base. The central shaft inside the winding wheel extends above the rack and is fixedly fitted with a gear, and the rack meshes with the gear.

[0010] Furthermore, the base has a first guide groove, and the bottom of the hinge seat at the front end of the folding plate is provided with a slider, which is adapted to slide in the first guide groove.

[0011] Furthermore, a retractable cleaning component is installed at the rear end of the protective cover. The cleaning component includes a cleaning brush, an elastic seat, and a fixed seat. The fixed seat is vertically fixed to the rear end connection of the protective cover, the elastic seat is mounted on the fixed seat, and the bottom of the elastic seat is provided with a cleaning brush.

[0012] Furthermore, the base has a waste trough at its front end, which is located on the front side of the hinge seat of the folding plate. When the folding plate is tilted upward and the protective cover is rolled up to the bottom of the base, the cleaning brush can clean the photovoltaic panel from top to bottom, and the accumulated dust after cleaning is collected in the waste trough.

[0013] Furthermore, a storage box is fixed to the bottom of the base, and a storage roller is rotatably installed inside the storage box via a support seat. The roller shaft inside the storage roller is connected to a drive motor, and a material passage hole is provided at the front end of the storage cavity.

[0014] Furthermore, a tensioning wheel is fixed at the rear end of the guide rail at an angle. After the traction rope is led out from the rear end of the guide rail, it passes around the tensioning wheel and then winds around the take-up wheel below the guide rail.

[0015] Furthermore, the base is fixed with a vertical pole, and each vertical pole is equipped with a clamp. The clamp includes two clamping blocks arranged symmetrically. The two clamping blocks are detachably connected by bolts, and the top of the clamping blocks is fixed to the bottom of the vertical pole by a U-shaped seat.

[0016] The beneficial effects of the above technical solution are as follows: The photovoltaic module mounting bracket for corrugated steel tile roofs provided by this invention has a compact and reliable structure. It can simultaneously drive the protective cover to extend and retract, and clean the modules, while the folding plate swings via the drive seat, thus forming a collaborative operation mechanism and effectively reducing the overall complexity and energy consumption of the mounting bracket. In this invention, the protective cover uses flexible, high-strength materials to reduce wind load. Its rigid edge connection and guide rail form an impact-resistant skeleton. Combined with the arc-shaped transition section design of the guide rail, it can form a hard barrier during hail impacts, protecting the photovoltaic panels. Simultaneously, the inclined tensioning wheel design at the rear end of the guide rail effectively solves the problem of sudden force changes caused by instantaneous changes in the length of the traction rope or transmission gaps during the dynamic extension and retraction of the flexible protective cover, effectively extending its service life and ensuring smooth and reliable operation.

[0017] In this invention, the cleaning brush is elastically pressed against the surface of the photovoltaic panel by a spring assembly, and the bidirectional cleaning stroke covers the entire surface of the photovoltaic panel. Since the protective cover and the folding plate do not remain parallel during synchronous movement, multiple springs in the spring seat of the cleaning component enable the cleaning brush to adapt to the undulations and tilt changes of the panel surface, thereby efficiently removing deposits attached to the photovoltaic panel surface. The waste material after cleaning can also be collected directionally through the waste trough between the folding plate and the guide track to avoid secondary pollution.

[0018] In this invention, the protective cover is rolled up and hidden under the base during storage, and the cleaning brush retracts simultaneously into the gap between the cover and the folding panel, ensuring zero light obstruction and zero wind resistance increase, thus maximizing power generation efficiency. This invention seamlessly integrates extreme weather protection, daily dust cleaning, and folding storage of photovoltaic panels. Through a purely mechanical structure, it achieves functional reuse and energy consumption optimization, significantly improving the survivability of corrugated steel roof photovoltaic systems in harsh environments and their overall life-cycle power generation benefits.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1: This example aims to provide a photovoltaic module installation bracket for corrugated steel roofs. It is primarily used for the active folding and protective storage of photovoltaic modules installed on corrugated steel roofs. Addressing the problem in existing technologies where photovoltaic modules installed on corrugated steel roofs are easily damaged by direct impacts from extreme weather events such as hail, this invention integrates a dynamic storage and protection mechanism. When severe weather such as hail is detected or predicted, the photovoltaic panels can be folded and retracted while a protective cover is placed over the entire photovoltaic panel, forming a protective barrier to prevent damage. When the weather improves, the photovoltaic panels can be safely unfolded and reset to resume power generation, thus significantly improving the safety of photovoltaic modules under extreme weather conditions.

[0022] like Figure 1-6 As shown in the figure, this embodiment provides a photovoltaic module mounting bracket for a color steel tile roof, including a base 1, a protective component 3 and at least one set of folding components 2 disposed on the base 1. A vertical pole is fixed to the bottom of the base 1, and a clamp 4 is fixed to the bottom of each vertical pole. The mounting bracket is fastened to the corrugated surface of the color steel tile by the clamp 4. The clamp in this embodiment includes two symmetrically arranged clamping blocks 41. The bottom of each clamping block 41 has an arc-shaped structure. When the two clamping blocks 41 are joined together by bolts, the bottom of the clamp forms a channel with a cylindrical cross section for fixing and clamping the corrugated surface of the color steel tile. The top of the clamp forms a support platform. A U-shaped seat 42 is detachably fixed to the support platform by bolts. The vertical pole on the base 1 is locked and fixed in the U-shaped seat 42 by bolts, so that the clamp forms a detachable structure, which is convenient for construction.

[0023] like Figure 1-3 As shown, at least one set of folding components 2 is hinged to the base. It should be noted that in this embodiment, at least one set of folding components is set on the base. In actual application, multiple sets can be evenly arranged on the base according to the arrangement of the photovoltaic module array on the corrugated steel roof, so that the protective cover of the protective component 3 can simultaneously cover the multiple sets of folding panels arranged in the row, thus playing a protective role. This embodiment uses one set as an example for introduction.

[0024] In this embodiment, each folding assembly 2 includes a folding plate 25, a drive seat 23, and a diagonal brace 24. A track groove 29 is formed on the base 1 along the front-to-back direction. A screw 22 is rotatably installed inside the track groove 29. The drive seat 23 is threadedly connected to the screw 22 and fitted within the track groove 29. One end of the screw 22 is connected to a folding motor 21, so that when the folding motor 21 operates, it drives the screw 22 to rotate, causing the drive seat 23 to reciprocate back and forth within the track groove 29. Furthermore, the folding motor 21 can be connected to a separate drive source or optionally electrically connected to a photovoltaic module, allowing the photovoltaic module to provide it with power.

[0025] The photovoltaic panel 5 is fixedly mounted on the folding plate 25. The front end of the folding plate 25 is hinged to the base 1. The diagonal brace 24 is inclined between the drive seat 23 and the folding plate 25, and both ends of the diagonal brace 24 are hinged to the drive seat 23 and the folding plate 25 respectively. Thus, when the drive seat 23 moves back and forth, the diagonal brace 24 can pull the folding plate 25 to swing upward around the hinge point or fold downward. When multiple sets of folding plates are arranged on the base, the rotating shafts on the front side of the folding plates can be connected together, and the reciprocating motion of multiple sets of folding plates can be driven synchronously by one or two folding motors located at both ends.

[0026] Furthermore, such as Figure 2 and Figure 3 As shown, guide rods 35 are provided vertically on the left and right sides of the folding plate 25. Guide sleeves 36 are slidably fitted on the guide rods 35, and the rear end of the folding plate 25 is hinged to the guide sleeves 36. The hinge seat 26 at the front end of the folding plate 25 can reciprocate on the base 1 when the folding plate 25 swings. In the specific implementation structure, a first guide groove 27 is opened on the base 1. A slider is provided at the bottom of the hinge seat 26 at the front end of the folding plate 25. The slider is adapted to slide in the first guide groove 27. When the folding plate 25 is driven to swing, the hinge shaft 28 on the folding plate 25 rotates, which can drive the hinge seat 26 to slide back and forth along the first guide groove 27.

[0027] like Figure 3 and 4 As shown, the protective component 3 is located on the outside of the folding component 2. When the folding component 2 is pushed outward, the protective cover 32 is simultaneously driven to swing upward, and the protective cover 32 is rolled up from above the folding plate 25 to below the base 1. In the event of severe weather such as strong hail, the protective cover 32 can be covered above the photovoltaic panel 5 by retracting the folding plate 25, thus achieving the effect of protection.

[0028] In the specific implementation structure, the protective component 3 in this embodiment includes a guide rail 31, a protective cover 32, a guide rod 35, a traction rope 8, and a winding wheel 95. The guide rail 31 is located above the folding plate 25, and the guide rod 35 is located on the left and right sides of the guide rail 31 and the folding plate 25. Two guide sleeves 36 are provided vertically at intervals on the guide rod 35. The two guide sleeves 36 are respectively hinged to the folding plate 25 and the guide rail 31, and the upper and lower guide sleeves 36 are fixedly connected together. In this way, when the folding plate 25 swings, the guide rail 31 above it will swing synchronously through the two connected guide sleeves 36.

[0029] Furthermore, the front end of the guide rail 31 is an arc-shaped transition section 39. A second guide groove 37 is opened on the base 1 corresponding to the transition section 39. A slide block 38 is fitted inside the second guide groove 37. The front end of the slide block 38 is hinged to the transition section 39 of the guide rail 31. Thus, when the folding plate 25 drives the guide rail 31 to swing through the guide sleeve 36, the slide block 38 moves back and forth along the second guide groove 37, thereby driving the hinge point of the guide rail 31 to move laterally in the horizontal direction.

[0030] In this embodiment, the inner cavity of the guide track is hollow, and the protective cover 32 is located between the left and right guide tracks 31. The left and right sides of the protective cover 32 extend into the inner cavity of the guide track 31 and are fixedly connected to the traction rope 8 inside it. In this embodiment, the protective cover 32 is made of flexible material, and a rigid connecting part 71 is fixed at the rear edge of the protective cover 32. The rigid connecting part 71 is fixedly connected to the traction rope 8. The front end of the protective cover 32 is fixedly wound onto the collecting roller 342 below the base 1. The roller shaft inside the collecting roller 342 is connected to the drive motor.

[0031] like Figure 5 As shown, the output end of the traction rope 8 extends from the rear end of the guide rail 31, winds around the bottom of the guide rail 31, and is finally fixedly wound onto the take-up reel 95 on the base 1. Additionally, to ensure the accuracy of the traction rope 8's lead-out path, it can also be... Figure 5 A guide ring is fixed below the guide rail 31, so that the end of the traction rope 8, after passing through the guide ring, is wound around the take-up reel 95. The take-up reel 95 is connected to the hinge shaft 28 of the folding plate 25 via the transmission assembly 9, so that when the hinge seat 26 on the folding plate 25 slides laterally in the first guide groove 27, it can synchronously drive the take-up reel 95 to rotate, thereby driving the protective cover 32 to be pulled up to cover or store under the action of the traction rope 8.

[0032] like Figure 5 and 6As shown in the specific implementation structure, in this embodiment, the transmission component 9 includes a connecting rod 91, a rack 92, a slide rail 93, and a gear 94. The two ends of the hinge shaft 28 of the folding plate 25 extend to the outer side of the hinge seat 26 and are rotatably fitted with the connecting rod 91. The rack 92 is fixedly connected to the rear side of the connecting rod 91. The slide rail 93 is fixed on the base 1 in the horizontal direction. The rack 92 is adapted to be fitted on the slide rail 93 below. When the hinge seat 26 moves back and forth along the first guide groove 27, the connecting rod 91 and the rack 92 are synchronously driven to move back and forth along the extension direction of the slide rail 93 through the hinge shaft 28. The take-up reel 95 is rotatably mounted on the base 1. The central shaft inside the take-up reel 95 extends above the rack 92 and is fixedly fitted with a gear 94. The rack 92 meshes with the gear 94. Thus, when the rack 92 is driven to move linearly, the meshing of the rack 92 and the gear 94 synchronously drives the gear 94 to rotate, thereby causing the take-up reel 95 to rotate, thereby driving the traction rope 8 to loosen or wind, and thus achieving control of the protective cover 32.

[0033] like Figure 5 As shown, a storage box 34 is provided below the base 1. A storage roller 342 is rotatably mounted inside the storage box 34 via a support base 341. The roller shaft inside the storage roller 342 is connected to a drive motor (not shown in the figure) to control the forward winding or reverse unwinding operation of the storage roller. A material passage hole is provided at the front end of the storage box 34 for the protective cover 32 to enter and exit. Furthermore, a guide roller 33 is also provided at the front end of the base 1. This guide roller 33 is a non-powered roller. The protective cover 32 passes through the transition section 39 at the bottom of the guide rail 31 and enters the storage box 34 via the guide roller 33 to be stored.

[0034] In this invention, when the photovoltaic panel 5 needs to be covered and protected, the storage roller 342 is driven to rotate. Simultaneously, under the action of the drive seat 23, the diagonal support rod 24 drives the folding plate 25 to tilt downwards and retract. During this process, the hinge seat 26 at its front end moves forward. Through the fitting of the rack 92 and gear 94, the winding wheel 95 is driven to rotate, so that the traction is wound around the winding wheel 95. This, in turn, pulls the protective cover 32 upwards along the guide track 31 via the traction rope 8 until it completely covers the photovoltaic panel 5. Conversely, when the folding plate 25 is raised, the storage roller 342 is driven to rotate in the opposite direction. Simultaneously, under the action of the transmission component 9, the traction rope 8 is released until the protective cover 32 moves downwards to a position below the photovoltaic panel 5. It is important to note that during the linkage process, the winding rotation of the storage roller 342 and the winding rotation of the winding wheel 95 must be matched to avoid interference during use.

[0035] Working principle explanation: The photovoltaic module mounting bracket for color steel tile roofs provided in this embodiment is actually installed on the color steel tile roof using clamps. On the one hand, in normal power generation, the diagonal brace 24 supports the folding plate 25 to an inclined angle, causing the folding plate 25 to drive the photovoltaic panel 5 to unfold, so that the photovoltaic panel 5 can fully receive sunlight. At this time, the protective cover 32 is located below the guide rail 31, and the storage roller 342 under the base 1 stores the protective cover 32. On the other hand, in extreme weather conditions, the protective mechanism is activated. The folding motor 21 drives the screw 22 to rotate, and the drive seat 23 moves backward along the track groove 29. The diagonal brace 24 pulls the folding plate 25 to swing downward around the front hinge point, so that the photovoltaic panel 5 reaches the maximum folding angle and completes the folding and storage. When folding downward, the hinge seat 26 at its front end moves forward along the first guide groove 27. The hinge shaft 28 rotates, the connecting rod 91 drives the rack 92 to move horizontally on the slide rail 93, the rack 92 drives the gear 94 to rotate, and drives the winding wheel 95 to tighten the traction rope 8. The traction rope 8 pulls the rigid connecting part 71 of the protective cover 32 through the inner cavity of the guide rail 31, so that it unfolds from the bottom of the base 1 along the guide rail 31. At the same time, the storage roller 342 is driven by the drive motor to release the protective cover 32. The protective cover 32 completely covers the folded photovoltaic panel 5 through the guide roller 33 and the arc transition section 39 at the front end of the guide rail 31, forming a continuous and taut flexible protective barrier. The impact force of the hail is absorbed by the protective cover 32 and the guide rail 31 together, and the photovoltaic panel 5 is not directly impacted. The guide rail 31 swings down synchronously with the folded plate 25 under the drive of the guide sleeve 36. The slide seat 38 at its front end slides along the second guide groove 37 to ensure that the protective cover 32 covers the trajectory accurately. Once the weather improves, the folding motor 21 reverses, the drive seat 23 moves forward to push the diagonal brace 24 to lift the folding plate 25, and the folding plate 25, through the guide sleeve 36, synchronously drives the guide rail 31 to lift upward to the standby position, thereby resetting the photovoltaic panel 5 to the power generation angle. The hinge seat 26 moves backward to drive the rack 92 to retract, the gear 94 reverses to cause the winding wheel 95 to release the traction rope 8, and the drive motor synchronously drives the storage roller 342 to reverse, retracting the protective cover 32 from the surface of the photovoltaic panel 5 downward into the storage box 34.

[0036] The photovoltaic module mounting bracket for corrugated steel tile roofs provided by this invention achieves synchronized folding and protection through mechanical linkage, enabling rapid response under extreme weather conditions, preventing direct impact of strong hail on photovoltaic panels, significantly reducing the cost of replacing photovoltaic panels due to extreme weather, and effectively protecting the photovoltaic system on corrugated steel tile roofs under extreme weather conditions.

[0037] Example 2 is based on Example 1. The similarities between this example and Example 1 will not be repeated. The difference is that a cleaning component 7 is installed at the rear end of the protective cover 32 in this example.

[0038] like Figure 7As shown, in this embodiment, the cleaning component 7 includes a cleaning brush 74, an elastic seat 73, and a fixed seat 72. The rear end of the protective cover 32 is a rigid connecting part 71, and the bottom of the connecting part 71 is vertically fixed to the fixed seat 72. The elastic seat 73 is mounted on the fixed seat 72. The inner cavity of the elastic seat 73 is hollow, and multiple sets of springs 75 are evenly distributed in its inner cavity. The bottom of each set of springs 75 is fixedly connected to a docking plate, and the bottom of the docking plate is fixed to the cleaning brush 74. Thus, under the action of the springs 75, the cleaning brush 74 can elastically extend and retract. With this configuration in this embodiment, when the protective cover 32 is pulled up from bottom to top until the rear end of the guide rail 31 fully covers the photovoltaic panel, the cleaning brush simultaneously cleans the surface of the photovoltaic panel from bottom to top. When the protective cover is retracted downwards, the cleaning brush simultaneously drives the cleaning brush to clean the surface of the photovoltaic panel from top to bottom again, thereby achieving the cleaning of dust accumulation on the surface of the photovoltaic panel.

[0039] Furthermore, when the protective cover 32 is pulled to the lower end of the guide rail 31, the cleaning brush 74 is located between the folding plate 25 and the protective cover 32. Therefore, in practical applications, a waste trough can be opened at the front end of the base 1, between the folding plate 25 and the guide rail 31, so that the dust on the photovoltaic panel 5 can be swept into the waste trough for collection.

[0040] Example 3, based on Examples 1 and 2, retains the similarities but differs in that, in practical application, to prevent the traction rope 8 from momentarily slackening or tightening during the swinging of the folding plate 25 and thus damaging the flexible material protective cover 32, a tensioning wheel is fixed at an angle at the rear end of the guide rail 31. Figure 8 As shown, the traction rope 8 extends from the rear end of the guide rail 31, passes around the tension wheel, and then winds around the take-up wheel 95 below the guide rail 31. Alternatively, in practical applications, the guide roller 33 can be replaced with a tension wheel, and the protective cover 32 can extend from below the guide rail 31, pass around the tension wheel on the front side of the base 1, and be stored in the storage box 34 to solve this problem.

[0041] This embodiment effectively solves the problem of sudden force changes caused by instantaneous changes in the length of the traction rope or transmission gaps during the dynamic extension and retraction of the flexible protective cover. It greatly reduces the risk of tearing and damage to the protective cover, significantly extends its service life, and ensures smooth and reliable operation.

[0042] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. The basic concept of the present invention lies in achieving simultaneous protection and cleaning of photovoltaic panels through a mechanical coupling method of folding plates linked to the protective cover. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
