Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic panels, in particular to a photovoltaic power generation floor tile for cultural tourism landscape. Background Art

[0002] With the continuous improvement of environmental protection awareness, more and more cities have begun to pay attention to green environmental protection construction. Against this background, photovoltaic landscape came into being. Photovoltaic landscape is a green and environmentally friendly product that integrates landscape and photovoltaic power generation. Among them, photovoltaic floor tiles are mainly composed of anti-slip tempered thickened power generation glass and controllers, and can be used in various places such as pedestrian walkways, scenic spots, parks, communities, industrial parks, etc. The surface of photovoltaic floor tiles is anti-slip, and has the characteristics of safety, reliability, strong power generation capacity, and convenient installation. Since photovoltaic floor tiles can directly convert light energy into electrical energy through solar energy, they can provide lighting, smart bus stops, electronic display screens, scenic off-grid lighting, 5G base stations, electric vehicle charging devices and other application scenarios for places in the application. Moreover, if sensors are installed, photovoltaic floor tiles can also monitor ground subsidence, water accumulation and other conditions, with better data collection capabilities, providing more convenience for urban management and citizens' travel.

[0003] An existing photovoltaic power generation floor tile has a glass panel on the top surface of the battery cell, which is bonded and connected to the battery cell through an EVA film layer, and a back panel wrapped on the bottom surface, which double-sidedly protects the battery cell for normal operation.

[0004] The above-mentioned existing technical solutions have the following defects: the top wall of the battery cell generally adopts a single-layer glass panel in consideration of the light transmittance and hardness requirements; photovoltaic floor tiles are often stepped on by pedestrians, and the single-layer glass panel is easily broken when colliding with hard objects such as gravel, mud and sand particles; and because the battery cells are generally made of monocrystalline silicon or polycrystalline silicon, which are relatively brittle, the battery cells can be easily damaged when the single-layer glass panel breaks, and its structural strength needs to be improved. Utility Model Content

[0005] The purpose of the utility model is to provide a photovoltaic power generation floor tile for cultural tourism landscape.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The invention comprises a rectangular shell, wherein a battery slot is provided on the top wall of the shell, a plurality of battery cells are embedded in the battery slot, a bottom plate is provided on the bottom wall of the battery cells, a sealing adhesive layer is provided on one side of the bottom plate close to the battery slot, an EVA adhesive film layer is provided on the battery cells, a junction box electrically connected to the battery cells is fixedly provided on the top wall of the shell, a receiving plate is extended on the edge of the shell, a rectangular composite glass panel is provided on the receiving plate, the composite glass panel covers the battery cells in the battery slot, the composite glass panel comprises a bottom plate tempered glass, the bottom plate tempered glass is bonded to the receiving plate, the top wall of the bottom plate tempered glass is covered with a convex tempered glass with the convex surface facing outward, and a sticky transparent adhesive layer is sandwiched between the convex tempered glass and the bottom plate tempered glass.

[0008] By adopting the above technical scheme, the composite glass panel adopts a double-layer laminated glass design with good structural strength, the bottom tempered glass adopts a flat structure and a layer of sticky transparent adhesive layer is sandwiched between the convex tempered glass, and the outermost convex tempered glass is also provided with anti-slip texture. Even if the glass is broken, the fragments will be stuck to the sticky transparent adhesive layer, which can prevent the convex tempered glass from breaking and splashing to injure people. The bottom tempered glass can effectively isolate the surface glass fragments from invading, effectively preventing the fragments from piercing or penetrating the battery cell, and has a good protective effect. The convex tempered glass has a convex surface facing outward, and the curved convex surface can effectively disperse the surface load compared to the flat surface, avoiding load concentration and damage to the convex tempered glass, and effectively improving the structural strength. At the same time, the structure of the convex mirror has a good light gathering effect. Since the area of ​​the composite glass panel is larger than the battery cell, it can gather light on a large scale to shine on the battery cell, thereby increasing the power generation capacity of the battery cell.

[0009] Furthermore, the shell is made of aluminum alloy or steel, and the sticky transparent adhesive layer is EVA film or PVB film.

[0010] By adopting the above technical solution, the aluminum alloy and steel shell have good structural strength, ensuring that the equipment is not easily deformed. The EVA film or PVB film has good adhesion and strong light transmittance, ensuring the transmittance of light.

[0011] Furthermore, an elastic rubber layer that wraps the composite glass panel is extended from the outer edge of the receiving plate, and the elastic rubber layer is sequentially provided with a first horizontal plane, a first vertical plane, a second horizontal plane and a second vertical plane along the periphery, and the outer walls of the first horizontal plane and the first vertical plane are fixedly provided with rubber convex strips along the length direction, and the second horizontal plane and the second vertical plane are provided with mating grooves that match the rubber convex strips.

[0012] By adopting the above technical solution, the setting of the elastic rubber layer has a good buffering effect, and it can adaptively deform elastically when photovoltaic modules are installed in batches, thereby avoiding rigid collision of fragile corners of adjacent composite glass panels and causing damage to the panels. The rubber convex strips cooperate with the fitting grooves, and the adjacent composite glass panels are closely close. The concave and convex structures are nested to make the panels firmly combined, thereby avoiding misalignment of the composite glass panels and affecting the lighting effect.

[0013] Furthermore, drainage grooves are formed through four ends of the elastic rubber layer near four corners of the composite glass panel.

[0014] By adopting the above technical solution, the setting of the drainage groove has a good drainage effect, which effectively prevents water from accumulating on the surface of the composite glass panel and ensures that the convex tempered glass continues to maintain the focusing effect.

[0015] Furthermore, a plurality of partitions are arranged between the battery sheets, and the partitions are fixedly arranged on the bottom wall of the battery slot to contact the composite glass panel.

[0016] By adopting the above technical solution, the setting of the partition further improves the supporting effect of the shell on the composite glass panel, prevents the composite glass panel from excessively squeezing the battery cell and causing internal damage, and makes the load transfer more uniform and reasonable.

[0017] In summary, the beneficial technical effects of the utility model are:

[0018] 1. The bottom tempered glass, convex tempered glass and sticky transparent adhesive layer are used to effectively isolate the surface glass fragments from invading, effectively preventing the fragments from piercing or penetrating the battery cells and greatly improving the panel structure strength;

[0019] 2. The convex tempered glass with the convex surface facing outward is used, which can gather light over a large area and shine it on the battery cell, thereby increasing the power generation efficiency of the battery cell;

[0020] 3. The elastic rubber layer, rubber convex and fitting groove are used to prevent the fragile corners of adjacent composite glass panels from rigid collision and damage to the panels, and to prevent the composite glass panels from being misaligned and affecting the lighting efficiency.
