Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to a foldable photovoltaic bracket that is easy to install and recycle. Background Technology

[0002] In the field of photovoltaic equipment installation, traditional photovoltaic brackets often suffer from complex structures, large size, and time-consuming and labor-intensive installation and recycling processes. Most brackets require multiple people to complete the deployment, and it is difficult to ensure the flatness of the modules during installation, affecting the working efficiency of the photovoltaic modules. At the same time, the recycling process is cumbersome because the components cannot be retracted synchronously, which consumes a lot of manpower and time, hindering the rapid transfer and reuse of photovoltaic equipment and failing to meet the needs of rapid deployment and recycling of photovoltaic brackets in emergency or temporary situations. Summary of the Invention

[0003] This utility model discloses a foldable photovoltaic (PV) bracket, aiming to solve the problems of labor-intensive installation and the need for multiple people to work together in traditional PV brackets. It also addresses the difficulties in ensuring component flatness during installation and the inability to simultaneously fold components during retrieval, thus meeting the needs for rapid deployment and reuse.

[0004] (I) Device Composition

[0005] The foldable photovoltaic support system comprises a support body, photovoltaic modules, connecting and folding components, locking components, and a drive component, as detailed below:

[0006] 1. Support Body: Composed of two rows of columns arranged equidistantly along the longitudinal direction. Each column has self-locking casters symmetrically installed on both sides of its bottom for movement and fixation. One end of each row of columns is equipped with a winch and a handle, while the other end has a fixed wheel.

[0007] 2. Photovoltaic module: It consists of multiple photovoltaic panels. Adjacent photovoltaic panels are connected by a pair of hinges and can be folded up along the folding direction. In the retracted state, it folds into a "W" shape, which effectively saves space.

[0008] 3. Connecting and folding components:

[0009] (1) Steel cable-lightweight guide rail assembly structure: including a steel cable passing through the top of two columns and a lightweight guide rail welded to the lowest folding point of the photovoltaic module, the photovoltaic module can slide into position along the steel cable-lightweight guide rail assembly structure; the lightweight guide rail includes a roller assembly, a roller bracket, and a through hole for fitting a pin. The roller bracket is welded to the lowest folding point of the photovoltaic module, and the roller assembly is mounted on the roller bracket and can slide along the steel cable.

[0010] (2) Telescopic Adjustable Support: Distributed at intervals on the top of the column, the height of the photovoltaic modules can be finely adjusted during installation to ensure the flatness of the modules and thus improve power generation efficiency. The telescopic adjustable support includes a fixed sleeve, a rack, a gear, a connecting shaft, and a handwheel. The rack has a latch that engages with a slot on the fixed sleeve welded to the side of the column, allowing the rack to slide up and down along the slot. Rotating the handwheel drives the gear through the connecting shaft, which in turn drives the rack to slide up and down along the slot of the fixed sleeve, thus enabling the telescopic adjustable support to finely adjust the height of the photovoltaic modules.

[0011] (3) Synchronous column stabilizing hinge mechanism: It is set between adjacent columns, and its specific structure is as follows:

[0012] The synchronous column-stabilizing hinge mechanism consists of hinge arms made of Q235 steel plate with a galvanized surface to enhance rust resistance. This mechanism comprises two hinge arms of matching lengths, cross-hinged by a central pin-sleeve combination to form an "X"-shaped linkage structure.

[0013] A rotating locking pin is provided at the midpoint of the cross hinge joint of the hinge arms. Specifically, the midpoint pin-sleeve assembly includes a midpoint pin and a sleeve. For the two cross hinge arms, one hinge arm has a midpoint pin, and the other hinge arm has a sleeve, allowing the midpoint pin to rotate freely within the sleeve. Simultaneously, the sleeve and the midpoint pin have pre-drilled through holes for mutual engagement. When the synchronous stabilizing hinge mechanism is extended to its working angle, the rotating locking pin can pass through these through holes to fix the angle of the synchronous stabilizing hinge mechanism.

[0014] The hinge arm is hinged to the ear plate on the column in the following way: a through hole matching the pin is provided on the hinge arm and the ear plate. After the pin is passed through the through hole, a pin is inserted to form a stable hinge between the hinge arm and the ear plate.

[0015] Through the above structural design, this synchronous column-stabilizing hinge mechanism not only enables the synchronous sliding of adjacent columns through the traction of the moving rollers and steel cables, but also, when the foldable photovoltaic support is in operation, the hinge angle can be fixed by inserting a rotating locking pin, transforming the "X"-shaped linkage structure into a rigid structure, thus forming a rigid triangular support. Utilizing its rigidity, it can effectively transmit lateral forces, limit the lateral displacement of the columns, and work with the columns to resist lateral loads, ensuring that the columns always maintain a vertically stable state, thus strongly guaranteeing the overall stability of the structure.

[0016] 4. Locking components: The central cross hinge point of the synchronous column stabilizing hinge mechanism is equipped with a rotating locking pin. After installation, the rotating locking pin is inserted to fix the hinge angle, making it a rigid structure. It also includes a pin. The lightweight guide rail and the column are respectively opened with through holes adapted to the pin for fixing the photovoltaic module after it is in place.

[0017] 5. Drive Components: These include a winch and handle located at the end of the foldable photovoltaic support frame. The end of the steel cable is wound around the winch, and the other end of the cable is fixed to a fixed wheel. When the foldable photovoltaic support frame is retracted, rotating the handle simultaneously retracts the cable, causing the entire frame to fold back into its original position.

[0018] (II) Installation Method

[0019] The installation process is as follows:

[0020] 1. Frame Body Deployment: A single person pulls the starting end of the column, and the moving roller drives the column to move along the installation direction (longitudinal). The synchronous column stabilizing hinge mechanism unfolds synchronously with the column sliding. The two hinge arms rotate relative to each other through the central pin-sleeve combination, driving adjacent columns to maintain equal distance and move smoothly. Until all columns reach the preset baseline position, step on the self-locking device of the moving roller to fix the columns. At this time, insert the rotating locking pin into the mating through hole of the central pin and sleeve to fix the angle of the "X"-shaped linkage structure, turning it into a rigid triangular support to ensure the vertical stability of the columns.

[0021] 2. Unfold the photovoltaic module and slide it along the steel cable to the working position via the roller assembly on the lightweight guide rail.

[0022] 3. Use a pin to pass through the through hole on the lightweight guide rail and the column to lock the lightweight guide rail and the column; at the same time, raise the spaced telescopic fine-adjustment supports to the required height to ensure the flatness of the photovoltaic module.

[0023] 4. Check the levelness of the entire system and the tension of the steel cables; the system installation is now complete.

[0024] The installation method of this foldable photovoltaic (PV) bracket is primarily based on its unique structural design to achieve stable support and efficient operation of the PV modules. After installation, the locked synchronous column-stabilizing hinge mechanism forms a rigid triangular support, working with the columns to resist lateral loads and ensure overall structural stability. When each column reaches the installation baseline position, the moving rollers self-lock, preventing the foldable PV bracket from moving. A through-type steel cable at the top, along with spaced, extendable, fine-tuning supports, works together to ensure the PV modules are flat, thereby guaranteeing their efficient reception of solar energy for power generation. Simultaneously, the robust connections between components can stably withstand the weight of the PV modules and the influence of the external environment, ensuring the normal operation of the entire PV system.

[0025] (III) Recycling Method

[0026] When you need to move or store the stand, simply follow the recycling procedure to fold it up for later use. The recycling procedure is as follows:

[0027] 1. First, pull out the rotating locking pin in the middle of the synchronous stabilizing column hinge mechanism to restore the relative rotation ability between the middle pin and the sleeve, and release the rigid lock of the "X"-shaped linkage structure; at the same time, lower the telescopic fine-adjustment support and pull out the pin of the lightweight guide rail and the column.

[0028] 2. Push the photovoltaic module in the reverse direction. The photovoltaic module slides along the steel cable through the lightweight guide rail and is retracted to the starting end of the column in sequence, so that the photovoltaic module is folded into a "W" shape.

[0029] 3. Loosen the roller self-locking device, turn the handle to drive the winch, and the steel cable drives the synchronous stabilizing hinge mechanism under the action of the winch, so that the foldable photovoltaic bracket is folded and returned to its original position.

[0030] IV. Beneficial Effects

[0031] More efficient installation and retrieval: With the linkage of self-locking moving rollers and synchronous stabilizing hinge mechanism, the operation can be completed by a single person without the need for multiple people to cooperate, which greatly saves manpower and time and is suitable for the rapid deployment needs of emergency or temporary occasions.

[0032] Enhanced structural stability: The synchronous column stabilizing hinge mechanism forms a rigid triangular support through rotating locking pins, which can effectively resist lateral loads, control the lateral displacement of the column and the swaying of the components, and ensure the safety and reliability of the system.

[0033] Superior power generation efficiency: The steel cable and the telescopic micro-adjustable support work together to control the flatness error of the photovoltaic module within a reasonable range, ensuring that the module fully receives light energy and reducing the loss of power generation efficiency caused by insufficient flatness.

[0034] Easier to operate and reuse: The installation and recycling steps are clear, and the operation of the locking pin, latch, and winch is simple and requires no professional tools; after recycling, it folds into a "W" shape, greatly reducing its volume and making it easy to transport and reuse in multiple scenarios.

[0035] Better maintenance and economy: The components adopt standardized design and rust prevention treatment, and can be replaced individually, reducing maintenance costs; the use of conventional materials makes the manufacturing cost reasonable and facilitates large-scale promotion.

[0044] The technical solution of this utility model will be described in detail below with reference to specific embodiments. The embodiments are only used to explain this utility model and are not intended to limit the protection scope of this utility model.

[0045] Example:

[0046] This embodiment provides a foldable photovoltaic bracket, which aims to solve the problems of cumbersome installation and recycling, the need for multiple people to cooperate, and the difficulty in ensuring the flatness of components in traditional photovoltaic brackets. It is suitable for emergency power supply, temporary outdoor power generation and other scenarios.

[0047] (I) Device Composition

[0048] (1) Support body

[0049] It consists of two rows of columns 1 arranged longitudinally at equal intervals (each row contains 5 columns, made of Q235 steel, 1.2m high). Each column 1 has symmetrically installed self-locking casters 3 (heavy-duty casters, 100mm diameter) on both sides of its bottom. The self-locking device of the casters 3 adopts a spring-loaded buckle structure, which can be locked by stepping on the pedal. A winch 5 (300mm diameter) and a handle 6 (400mm length) are welded to one end (starting end) of the two columns 1, and a fixed wheel 8 with a diameter of 150mm is fixed to the other end (end end). The central axis of the winch 5 and the fixed wheel 8 are aligned at the same height.

[0050] (2) Photovoltaic modules 7

[0051] The photovoltaic module 7 consists of four monocrystalline silicon photovoltaic panels with a size of 1600mm×900mm. Adjacent photovoltaic panels are connected by a pair of 304 stainless steel hinges and can be folded up along the folding direction (longitudinal direction). In the retracted state, the photovoltaic module 7 is folded into a "W" shape by the hinges, and the overall length is reduced to 1 / 3 of the original length after folding.

[0052] (3) Connecting and folding components

[0053] 1. Steel cable-lightweight guide rail combination structure: The steel cable 4 running through the top of the two columns 1 is a galvanized steel strand with a diameter of 8mm and a breaking tensile strength ≥50kN; the lightweight guide rail 10 is welded to the lowest folding point of the photovoltaic module 7, including a roller assembly 1002 (polyurethane roller, diameter 50mm), a roller bracket 1001, and a through hole (diameter 12mm) for the matching pin. The roller assembly 1002 is mounted on the roller bracket 1001, and the roller bracket 1001 is welded and fixed to the reinforcing rib on the back of the photovoltaic panel, ensuring that the photovoltaic module 7 slides along the steel cable 4 using the lightweight guide rail 10.

[0054] 2. Telescopic Adjustable Support 9: Distributed at intervals on the top of the columns 1 (one set for every two columns), including a fixed sleeve 905 welded to the side of the column 1, a rack 904 (300mm long, 5mm pitch), a gear 903 (2mm module, 20 teeth), a connecting shaft 902 (12mm diameter), and a handwheel 901 (100mm diameter). The rack 904 has a buckle that engages with a groove on the inner wall of the fixed sleeve 905 for guidance; when the handwheel 901 is rotated, the gear 903 drives the rack 904 to slide up and down along the fixed sleeve 905 through meshing, with an adjustment range of 0-200mm and an accuracy of ±1mm.

[0055] 3. Synchronous stabilizing hinge mechanism 2: The synchronous stabilizing hinge mechanism 2 is installed between adjacent columns 1, and its specific structure is as follows:

[0056] The synchronous stabilizing hinge mechanism 2 consists of two hinge arms 201 of suitable length. The hinge arms 201 are made of Q235 steel plate (5mm thick) and galvanized to enhance rust resistance and adapt to humid outdoor environments. The two hinge arms 201 are cross-hinged via a central pin-sleeve assembly 205, forming an "X"-shaped linkage structure. Specifically, the central pin-sleeve assembly 205 includes a central pin 207 (10mm diameter, made of 45# steel) and a sleeve 208 (10.2mm inner diameter, 3mm wall thickness). Of the two cross hinge arms 201, the central pin 207 is welded and fixed to one hinge arm, while the sleeve 208 is welded to the corresponding position on the other hinge arm. The central pin 207 can rotate freely within the sleeve 208 (with a clearance of 0.1-0.2mm), enabling relative rotation of the hinge arms.

[0057] A rotating locking pin 204 (12mm in diameter, 80mm in length, made of 304 stainless steel) is provided at the central cross hinge point. The sleeve 208 and the central pin 207 have coaxial through holes (12.2mm in diameter). When the synchronous stabilizing hinge mechanism 2 is extended to the working angle, the rotating locking pin 204 can pass through the through hole to lock the "X" shaped structure into a rigid state.

[0058] The end of the hinge arm 201 is hinged to the ear plate 203 (8mm thick, Q235 steel) on the column 1. Specifically, both the end of the hinge arm 201 and the ear plate 203 have through holes (8.2mm in diameter) for the fitting pin 202 (8mm in diameter, 45# steel). After the pin 202 passes through the through hole, its end is inserted into a pin 206 (3mm in diameter, 20mm in length). The pin 206 and the radial hole of the pin 202 are interference-fitted to prevent the pin 202 from moving axially and to ensure the stability of the hinge structure.

[0059] (4) Locking components

[0060] 1. A rotating locking pin 204 is provided at the middle hinge intersection of the synchronous stabilizing column hinge mechanism 2. After insertion, it can lock the angle of the "X" shaped structure (locking range 60°-120°);

[0061] 2. A through hole (12mm in diameter) is made at the corresponding position of the lightweight guide rail 10 and the column 1. A 10mm diameter and 100mm long pin 11 is used to insert the pin to achieve rigid fixation between the photovoltaic module 7 and the column 1.

[0062] (5) Drive components

[0063] The end winch 5 is connected to the end of the steel cable 4 (the other end of the steel cable 4 is fixed to the end fixed wheel 8). The transmission ratio of the winch 5 is 1:10. When the handle 6 is turned, the entire cable can be pulled together by the steel cable 4. A single turn of the handle 6 can retract the steel cable by 150mm.

[0064] (II) Installation Process

[0065] 1. When a single person pulls the starting end of column 1, the moving roller 3 drives column 1 to move longitudinally, and the synchronous column stabilizing hinge mechanism 2 slides and unfolds with column 1. At this time, the hinge arm 201 achieves relative rotation through the cooperation of the central pin 207 and the sleeve 208, ensuring that the adjacent columns 1 maintain a uniform distance during the movement. When all columns 1 reach the preset baseline position (distance error ≤ 5mm), the self-locking pedal of the moving roller 3 is stepped on to fix the column 1.

[0066] Subsequently, the rotating locking pin 204 (made of 304 stainless steel) is inserted into the through hole of the central pin 207 and the sleeve 208 (fitting clearance 0.1-0.2mm) to ensure that the exposed length of the locking pin end is ≥15mm, so that the "X" shaped structure is locked as a rigid triangular support, ensuring the overall stability of the column.

[0067] 2. Photovoltaic module deployment

[0068] Unfold the "W"-shaped photovoltaic module 7 and slide it along the steel cable 4 to the working position via the roller assembly 1002 of the lightweight guide rail 10, so that the surface of the photovoltaic panel faces due south (tilt angle 30°). Insert the pin 11 into the through hole between the lightweight guide rail 10 and the column 1 to fix the photovoltaic module 7 laterally.

[0069] 3. Flatness adjustment

[0070] Rotate the handwheel 901 of the retractable fine-tuning support 9 to adjust the height of the photovoltaic module 7 by raising and lowering it via the rack 904. Use a level (accuracy 0.02mm / m) to check the surface of the photovoltaic panel to ensure that the overall flatness error is ≤3mm.

[0071] 4. System check

[0072] Check the tension of the steel cable 4 and the locking status of each rotating locking pin 204 and the latch 11. After confirming that there is no looseness, the installation is complete.

[0073] (III) Recycling Method

[0074] 1. Unlock parts

[0075] Rotate the rotating locking pin 204 of the synchronous stabilizer hinge mechanism 2: completely pull the locking pin out of the through hole between the central pin 207 and the sleeve 208, so that the hinge arm 201 can rotate freely around the central pin 207; at the same time, rotate the handwheel 901 of the telescopic fine-tuning support 9 to lower the rack 904 to the lowest position (retract into the fixed sleeve 905).

[0076] 2. Photovoltaic modules with 7 folds

[0077] The photovoltaic module 7 is pushed in the opposite direction, causing the lightweight guide rail 10 to slide along the steel cable 4 and fold into a "W" shape through the hinge, and then close to the vicinity of the starting end column 1.

[0078] 3. The main support structure is retracted.

[0079] Release the self-locking device of the moving roller 3, turn the handle 6 of the winch 5, and the steel cable 4 will retract under the action of the winch 5. The synchronous column stabilizing hinge mechanism 2 will drive the column 1 to slide synchronously towards the starting end until the adjacent columns 1 are brought together. Then push the whole thing to the storage position.

[0080] This embodiment, through the above-described structural and operational design, enables a single person to complete installation or retrieval within 30 minutes, controls the flatness error of the photovoltaic modules within 3mm, and minimizes the lateral displacement of the support column when resisting lateral loads, thus meeting the efficient deployment requirements for emergency and temporary scenarios.

[0081] This embodiment is only a preferred embodiment of the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
