Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to a prefabricated carbon steel photovoltaic bracket. Background Technology

[0002] Photovoltaic (PV) mounting systems are support structures used to install and fix solar photovoltaic (PV) panels. The ease of installation and the strength of the connections directly affect construction efficiency and operational safety. Existing PV mounting systems are typically assembled from multiple support rods connected by welding or screws. In actual construction, this often results in cumbersome installation steps, numerous fasteners, and low efficiency. Especially in rooftop, sloped, or high-altitude work environments, construction workers need to repeatedly adjust, align, and tighten multiple connectors, increasing labor costs and safety risks. Furthermore, due to differences in component dimensions, tolerances, or frame design, some mounting structures lack adaptability, necessitating temporary modifications, the addition of shims, or repositioning during installation. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the technical problem to be solved by this utility model is to propose an assembled carbon steel photovoltaic bracket, which adopts the following technical solution:

[0004] A prefabricated carbon steel photovoltaic bracket includes several support plates, with fixing components provided at both ends of the support plates;

[0005] The aforementioned fixing assembly includes a base with limiting arms on it, a support plate connected between the two limiting arms, a photovoltaic panel placed on the support plate, and its sides abutting against the limiting arms; it also includes a pressing assembly, the middle of which is rotatably connected to the limiting arms, and both ends of which are respectively provided with a pressing part and a transmission part. The transmission part is rotatably connected to a locking plate, which is detachably fixed to a first position or a second position of the limiting arms. When the locking plate is fixed in the first position, it pushes the transmission part to rotate inward, causing the pressing part to press against the photovoltaic panel. When the locking plate is fixed in the second position, it drives the transmission part to rotate outward, causing the pressing part to separate from the photovoltaic panel.

[0006] As a further improvement, the pressing assembly includes a pressing block and a transmission block, wherein the pressing block, the transmission block and the limiting arm are hinged to each other via the same pivot, the pressing block is provided with the pressing part and the transmission block is provided with the transmission part.

[0007] As a further improvement, the aforementioned transmission block is provided with several limiting protrusions around its hinge hole, and the aforementioned pressure block is provided with several corresponding limiting grooves. The aforementioned pressure block and transmission block can rotate relative to each other, and the angle is fixed by the aforementioned limiting protrusions and limiting grooves to achieve multi-level angle adjustment.

[0008] As a further improvement, the aforementioned pressure block is provided with a mounting groove, the aforementioned transmission block is rotatably connected to the interior of the aforementioned mounting groove, and can move back and forth along the axial direction of the aforementioned pivot. The aforementioned limiting groove is provided on one side of the inner wall of the aforementioned mounting groove, and a spring is fixed on the other side. The aforementioned spring is used to push the aforementioned transmission block, so that the limiting protrusion is inserted into the aforementioned limiting groove.

[0009] As a further improvement, the end of the aforementioned pressure block is bent downwards and fastened to the inside of the frame of the aforementioned photovoltaic panel.

[0010] As a further improvement, the end of the aforementioned transmission block is bent upwards, and the aforementioned locking plate is hinged to the end of the aforementioned transmission block.

[0011] As a further improvement, the aforementioned locking plate is magnetically attached to the first or second position of the aforementioned limiting arm.

[0012] As a further improvement, the aforementioned locking plate is provided with a retaining protrusion, and the aforementioned limiting arm is provided with a retaining groove that cooperates with the aforementioned retaining protrusion at the aforementioned first position and second position.

[0013] Further improvements include a number of longitudinal beams, which are perpendicular to the support plate and arranged parallel to each other at the bottom of the support plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Firstly, this invention uses a support plate to hold the photovoltaic panel. Fixing components on both sides of the support plate secure the two sides of the photovoltaic panel. A pressing component is rotatably connected to a limiting arm in the middle, with a pressing part and a transmission part at each end. A locking plate is rotatably connected to the transmission part and detachably fixed to a first or second position on the limiting arm. The pressing component and the locking plate achieve rapid locking of the photovoltaic panel. During installation, simply place the photovoltaic panel on the support plate and fix the locking plate to the first position; the transmission part then drives the pressing part to press the photovoltaic panel frame. For disassembly, simply reverse the operation of the locking plate to release the pressure. The entire process requires no bolts or special tools, significantly improving installation efficiency and making it suitable for the rapid deployment of large-scale photovoltaic arrays.

[0016] Secondly, in this invention, the transmission block and the pressure block adopt an adjustment structure with a limiting protrusion and a groove. Multiple angle adjustments between the two can be achieved by pressing and rotating the transmission block. Combined with a spring reset mechanism, during operation, only the spring resistance needs to be overcome to separate the limiting protrusion from the limiting groove to complete the angle adjustment. After releasing the spring, the limiting protrusion re-embeds into the limiting groove for locking. This structure not only adapts to the pressing requirements of photovoltaic panels of different thicknesses but also compensates for slight unevenness of the mounting surface, ensuring uniform pressure distribution and preventing localized stress damage to the components.

[0017] Thirdly, in this invention, the locking plate is fixed to the limiting arm by magnetic attraction, while the retaining protrusion and retaining groove restrict longitudinal sliding, preventing accidental disengagement due to vibration or strong winds. This further enhances the mechanical stability of the locking plate and improves the holding force and reliability in the locked state. The cooperation between the retaining protrusion and the retaining groove only restricts the longitudinal sliding of the locking plate. Users can overcome the retaining cooperation with a slight lateral force to open and close the lock. This is stable and easy to operate, facilitating quick confirmation of the locking status on the construction site and improving work efficiency and safety. Attached Figure Description

[0033] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0034] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. The terms "part," "side," "end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model.

[0035] like Figure 1 and Figure 2 As shown, this application provides a prefabricated carbon steel photovoltaic bracket, including several support plates 1, with fixing components at both ends of the support plates 1. Figures 1-4 As shown, the fixing assembly includes a base 2, on which limit arms 3 are provided. A support plate 1 is connected between the two limit arms 3 to support the photovoltaic panel 100. The two sides of the photovoltaic panel 100 abut against the limit arms 3 to form a preliminary limit. Further, it also includes a pressing assembly for pressing the photovoltaic panel 100. The middle part of the pressing assembly is rotatably connected to the limit arms 3, and both ends are respectively provided with a pressing part and a transmission part. The transmission part is rotatably connected to a locking plate 4. The locking plate 4 is detachably fixedly connected to a first position or a second position of the limit arms 3. When the locking plate 4 is fixed in the first position, it pushes the transmission part to rotate inward, causing the pressing part to press the photovoltaic panel 100. When the locking plate 4 is fixed in the second position, it drives the transmission part to rotate outward, causing the pressing part to separate from the photovoltaic panel 100.

[0036] In one specific embodiment, the limiting arm 3 is perpendicular to the base 2, and the locking plate 4 is parallel to the limiting arm 3 when it is in the first or second position. Figure 3 The locking plate 4 shown is in the first position, that is, the fixing component is in the state of locking the photovoltaic panel 100. In this state, the locking plate 4 and the limiting arm 3 are close together and locked. The locking plate 4 provides a force to the transmission part to prevent it from rotating outward, so that the pressing part firmly presses the edge of the photovoltaic panel 100. When it is necessary to release the photovoltaic panel 100, the locking state between the locking plate 4 and the limiting arm 3 is released, and then the pressing component is rotated outward. The pressing part tilts upward and separates from the photovoltaic panel 100, so the photovoltaic panel 100 can be removed. When rotating, the locking plate 4 and the limiting arm 3 are in the separated state, as shown in the figure. Figure 5As shown in the left half, when rotated to the second position, the locking plate 4 re-fits with the limit arm 3.

[0037] Furthermore, in the above embodiments, preferably, the overall bracket is made of Q355B carbon steel. A magnetic sheet, specifically a neodymium iron boron permanent magnet, is embedded on the side of the locking plate 4 near the limiting arm 3. Q355B carbon steel has good ferromagnetism, enabling it to form a stable magnetic connection with the neodymium iron boron magnet. This allows the locking plate 4 to adhere to the surface of the limiting arm 3 in both the first and second positions. Especially when the locking plate 4 is in the second position, the pressing component is in a normally open state, facilitating the installation of the photovoltaic panel 100. Compared with traditional mechanical fastening methods, the magnetic connection method reduces structural wear and assembly tolerance requirements, improves repeated service life, and allows construction personnel to complete the locking operation with one hand. It combines safety and reliability and is suitable for various installation environments.

[0038] Furthermore, such as Figure 5 As shown, the locking plate 4 is provided with a retaining protrusion 41, and the limiting arm 3 is provided with a retaining groove 31 at the first and second positions to cooperate with the retaining protrusion 41. The cooperation between the retaining protrusion 41 and the retaining groove 31 further enhances the mechanical stability of the locking plate 4 and improves the holding force and reliability in the locked state. The cooperation between the retaining protrusion 41 and the retaining groove 31 only restricts the longitudinal sliding of the locking plate 4. The user can overcome the retaining cooperation by applying a slight lateral force to achieve opening and closing, which is stable and easy to operate. This facilitates quick confirmation of the locked state at the construction site, improving work efficiency and safety.

[0039] like Figure 6 As shown, the pressing assembly specifically includes a pressing block 5 and a transmission block 6, as follows: Figures 3-5 As shown, the pressure block 5, the transmission block 6, and the limiting arm 3 are hinged to each other via the same pivot. The pressure block 5 is used to press the photovoltaic panel 100 and is provided with the aforementioned pressing part. The transmission block 6 is hinged to the locking plate 4 and is provided with the aforementioned transmission part.

[0040] In the above embodiment, the end of the pressure block 5 is bent downwards and fastened to the inner side of the frame of the photovoltaic panel 100. The end of the transmission block 6 is bent upwards, and the locking plate 4 is hinged to the end of the transmission block 6. When the locking plate 4 is in the first position, the upwardly bent transmission block 6 and the locking plate 4 together form a part that facilitates the application of force. Applying a lateral force to this part can disengage the locking plate 4 from the limiting arm 3. Correspondingly, in the above embodiment, the size of the retaining groove 31 is slightly larger than that of the retaining protrusion 41. When force is applied to the transmission block 6, the locking plate 4 tilts, and the slightly larger size of the retaining groove 31 is used to make way for the retaining protrusion 41, making the disengagement operation smoother.

[0041] Furthermore, the transmission block 6 is provided with several limiting protrusions 61 around its hinge hole, and the pressure block 5 is provided with several corresponding limiting grooves 51. The pressure block 5 and the transmission block 6 can rotate relative to each other, and the angle is fixed by the limiting protrusions 61 and the limiting grooves 51, realizing multi-level angle adjustment. This structure can pre-set the relative angle between the pressure block 5 and the transmission block 6 according to the thickness of the photovoltaic module frame, so that it fits the edge of the module precisely under pressure, avoiding unstable clamping or damage to the module due to over-pressure or under-pressure. On the other hand, the above structure can also adapt to situations where there are local undulations or incomplete flatness on the module mounting surface, and has better adaptability and pressure buffering capacity, which helps to extend the life of the photovoltaic panel and improve the long-term stability of the system.

[0042] like Figure 6 and Figure 7 As shown, preferably, the pressure block 5 is provided with a mounting groove 52, and the transmission block 6 is rotatably connected to the inside of the mounting groove 52. The size of the mounting groove 52 is slightly larger than the thickness of the transmission block 6, so that the transmission block 6 can move back and forth along the axial direction of the pivot. A limiting groove 51 is provided on one side of the inner wall of the mounting groove 52, and a spring 53 is fixed on the other side. The spring 53 is used to push the transmission block 6, so that the limiting protrusion 61 is inserted into the limiting groove 51. Figure 7 As shown, during use, the construction worker only needs to apply a slight external force to overcome the elasticity of the spring 53, pushing the transmission block 6 away from the limiting groove 51 along the pivot direction, causing the limiting protrusion 61 to temporarily disengage from its positioning. Then, the relative angle between the pressure block 5 and the transmission block 6 is adjusted. After adjustment, the worker releases the hand, and under the elastic force of the spring 53, the transmission block 6 automatically returns to its original position, and the limiting protrusion 61 re-inserts into the groove, achieving angle fixation. The entire process can be completed with one hand without the aid of tools, making it suitable for rapid on-site adjustments and the differentiated assembly needs of multiple batches of photovoltaic modules. In addition, the spring 53 return mechanism can effectively prevent the pressure block 5 from loosening due to vibration during operation, improving clamping stability, reducing maintenance frequency, and making it suitable for long-term outdoor use. It balances structural reliability and ease of operation, possessing excellent engineering adaptability.

[0043] As a preferred option, such as Figure 2 As shown, to further improve the stability of the support structure, several longitudinal beams 7 are also included. These longitudinal beams 7 are perpendicular to the support plate 1 and are arranged parallel to each other at the bottom of the support plate 1. Through the supporting cooperation between the longitudinal beams 7 and the support plate 1, a grid-like support structure is formed, which provides stronger structural support when supporting the weight of the photovoltaic panel 100 and coping with wind loads.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
