Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a foldable photovoltaic power generation support system for concrete roofs. Background Technology

[0002] Photovoltaic power generation, as a clean and low-carbon energy source, is widely used in distributed rooftop scenarios. Although traditional fixed rooftop photovoltaic (PV) brackets have a simple structure, they have revealed several limitations in actual long-term operation: First, the efficiency of transportation, warehousing, and on-site assembly is low, components are scattered, alignment is complex, manual procedures are complicated, and installation and maintenance costs are high; Second, they lack adaptability to sites and environments. In extreme weather conditions such as strong winds, typhoons, heavy rain, snow, or sandstorms, it is difficult to effectively protect the wind-exposed surfaces of the modules in a timely manner. The glass surfaces and frames of the modules are easily impacted or squeezed by snow accumulation, leading to hot spots, microcracks, and power output reduction; Third, many fixed brackets lack array-level coordinated movement and locking designs, making it difficult to quickly retract and restore the modules, affecting the availability and operation and maintenance safety of the power station.

[0003] To this end, this application designs a foldable photovoltaic power generation support system for use on concrete roofs. Through the combination of rolling guidance, hinge linkage and limit locking, it realizes the rapid folding / unfolding of multiple components and mutual shielding of panels, while taking into account lightweight and engineering feasibility. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model proposes a foldable photovoltaic power generation support system for concrete roofs.

[0005] A foldable photovoltaic power generation support system for concrete roofs, for installation on concrete roofs, includes a concrete counterweight, U-shaped columns, horizontal U-shaped rods, front and rear U-shaped purlins, and at least one rolling module consisting of photovoltaic modules and inclined rolling U-shaped rods, characterized in that: The two ends of the inclined rolling U-shaped rod are respectively provided with a front circular roller and a rear circular roller, which are guided and cooperate with the front U-shaped purlin and the rear U-shaped purlin, so that the rolling module can be folded and unfolded relative to the purlin along its length direction; adjacent rolling modules are rotatably connected by hinge-type connectors, and the rolling module is provided with a limiting pin for limiting its working position and folding position.

[0006] Furthermore, in order to better realize this utility model, the concrete counterweight, the horizontal U-shaped rod and the U-shaped column are connected by triangular connectors and bolts to form a support frame, and the front U-shaped purlin and the rear U-shaped purlin are fixed on the support frame.

[0007] Furthermore, in order to better realize this utility model, the front circular roller is rolled in the inner cavity of the front U-shaped purlin, and the rear circular roller is rolled in the inner cavity of the rear U-shaped purlin to support and guide the oblique rolling U-shaped rod and the photovoltaic module it carries.

[0008] Furthermore, in order to better realize this utility model, the hinge-type connecting parts are set into three sets between two adjacent sets of rolling modules, and are arranged alternately in the forward and reverse positions along the component column direction to limit the torsional offset of the component column during the folding process.

[0009] Furthermore, in order to better realize this utility model, the limiting pin is a removable limiting pin, the end of the inclined rolling U-shaped rod is fixed to a round shaft and is provided with a limiting hole for inserting the limiting pin, and the limiting pin is inserted into the corresponding limiting hole in the working position and the folded position to achieve positioning and locking.

[0010] Furthermore, in order to better realize this utility model, the end of the rolling module cooperates with the fixed inclined rolling rod. When folding, the end module is pushed to the predetermined position along the direction of the fixed inclined rolling rod and the limiting pin is inserted to realize folding and locking. When unfolding and restoring, the limiting pin is pulled out and pulled in the opposite direction until the array is flattened and then reset and locked.

[0011] The beneficial effects of this utility model are as follows: 1. The bracket system can be quickly folded and unfolded through mechanisms such as round rollers, hinged connectors, and rotating shafts, reducing on-site installation time and workload, and further reducing costs.

[0012] 2. While ensuring structural strength, use lightweight materials such as aluminum alloy to reduce the volume and weight after folding.

[0013] 3. The foldable photovoltaic support system design allows the photovoltaic panels to be folded and retracted before strong winds, typhoons, heavy rain, snow, and sandstorms arrive, reducing the risk of damage and surface contamination to the photovoltaic modules and extending their service life.

[0014] 4. The system design takes into account the installation angle of the bracket system, so that the tilt angle of the system can maximize the reception of effective light. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Figures 1-5 In a specific embodiment of this utility model, a concrete counterweight 1 is arranged on a concrete roof. A U-shaped column 2 is fixed to the counterweight 1 using triangular connectors 4 and bolts. A horizontal U-shaped rod 3 is connected to the U-shaped column 2 to form a support frame. Front U-shaped purlins 5 and rear U-shaped purlins 6 are respectively fixed to the frame and arranged relative to each other to form a predetermined installation angle. The photovoltaic module 10 is fixed to the inclined rolling U-shaped rod 7 via end pressure blocks 11. Front circular rollers 8 and rear circular rollers 9 are sequentially assembled on the round shafts fixed at both ends of the inclined rolling U-shaped rod 7. The front circular roller 8 is placed into the inner cavity of the front U-shaped purlin 5, and the rear circular roller 9 is placed into the inner cavity of the rear U-shaped purlin 6, so that the rolling module forms a rolling guide support.

[0020] When at least two sets of rolling modules exist, three sets of hinged connectors 12 are installed between adjacent sets of modules, and are arranged alternately in positive and negative orientations along the component column direction to limit lateral twisting and misalignment during folding and ensure coordinated rolling of the modules in the purlin direction. Limiting holes are reserved on the round shafts at the ends of each module, and limiting pins 13 are inserted to lock the working position.

[0021] Folding: Pull out the limiting pins 13 at the ends of each module, and push the end rolling module along the direction of the fixed inclined rolling rod 14 from the end of the array, so that it drives the adjacent modules to roll and fold in sequence; when the end module reaches the predetermined folding position, insert the limiting pins 13 into the corresponding limiting holes to lock the folding.

[0022] Restoration: Pull out the limiting pin 13 at the folded position of the end module, pull the end module in the opposite direction to the folding, so that each module rolls out along the U-shaped purlin until the array is flattened; then insert the limiting pin 13 into the limiting hole at the working position to lock the operating condition.

[0023] The U-shaped column 2, U-shaped purlin, horizontal U-shaped rod 3, triangular connector 4, hinged connector 12, and end pressure block 11 are made of aluminum alloy or other lightweight materials to reduce weight and improve corrosion resistance. The rollers can use wear-resistant coatings or stainless steel bearing structures to reduce rolling resistance and increase lifespan. In the folded state, the light-receiving surfaces of the photovoltaic modules 10 mutually shield each other, reducing wind load and impact from external objects.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
