Description

Technical Field

[0001] The invention relates to the technical field related to photovoltaic tile components, and in particular to a roof photovoltaic structure. Background Art

[0002] As a low-carbon renewable energy source, the amount of solar energy installed and used is increasing year by year. Nowadays, it is not difficult for us to see neatly installed photovoltaic systems on the ground and on the roofs of various types of buildings. For various types of buildings, installing photovoltaic products with power generation functions can effectively reduce the building's electricity consumption and achieve energy conservation and emission reduction effects, while also bringing economic benefits to building owners. Therefore, it has good promotion value. Most of the existing building photovoltaic systems are installed and renovated on the roof of the building, and the photovoltaic component products themselves will have a certain degree of functional duplication and construction duplication with the tiles and other building materials on the original building roof, and will also affect the aesthetics of the building to a certain extent. Therefore, the use of photovoltaic tile products that can be directly used as building materials has a good prospect.

[0003] General photovoltaic tiles for buildings usually combine base tiles with flat photovoltaic tiles, so that the roof tiles that originally only have sunshade and windproof functions are combined with solar cells to make full use of roof solar energy resources. There are also photovoltaic tiles that are made into a curved surface as a whole, which can be hung on the top of buildings such as pavilions and towers to further improve their aesthetics. For example, the CN212231392U curved photovoltaic module frame and curved photovoltaic module, through the convex parts and concave parts on the first frame and the second frame, can reduce the flatness of the installation surface caused by the curved photovoltaic module. It is required to ensure that two adjacent curved photovoltaic modules can be tightly overlapped together. However, this type of curved photovoltaic tiles still have some problems during use. For example, the fixed overlapped curved photovoltaic tiles cannot be adjusted, and the light-facing surface is limited, which affects the solar energy absorption efficiency. At the same time, external environmental dirt brought by wind and rain is easy to accumulate on the surface of the corrugated photovoltaic tiles, requiring frequent cleaning and maintenance. Due to the light-facing area of ​​the curved photovoltaic tiles themselves, if there is a lack of maintenance and cleaning, the efficiency of the curved photovoltaic tiles used over a long period of time will be greatly reduced. In view of this, in-depth research was conducted on the above-mentioned problems, which led to the creation of this case. Summary of the invention

[0004] The purpose of the present invention is to provide a roof photovoltaic structure to solve the problem mentioned in the above background technology that the curved photovoltaic tiles are limited by their own structure for fixed installation and the light-facing surface is limited, and dirt is easily accumulated on the surface, affecting the long-term operating efficiency.

[0005] To achieve the above object, the present invention provides the following technical solution: a roof photovoltaic structure, comprising:

[0006] The curved photovoltaic tiles are used for evenly laying on the roof of a building, and the curved base tiles are padded under the curved photovoltaic tiles. The curved photovoltaic tiles and the curved base tiles are alternately arranged laterally on the roof surface, and the curved photovoltaic tiles and the curved base tiles form a wavy corrugated structure as a whole;

[0007] A lap joint assembly is used for connecting the curved photovoltaic tile and the curved base tile. The outer frame of the curved photovoltaic tile is provided with a protective frame, and the left and right side ends of the curved base tile are arc-shaped support parts. The lap joint assembly is correspondingly arranged on the left and right side edges of the protective frame and the arc-shaped support part;

[0008] The support assembly is used to flexibly adjust the support of the curved photovoltaic tiles and the curved base tiles. The support assembly is arranged between the bottom of the curved base tiles and the roof of the building, and the left and right ends of the curved base tiles form a movable adjustment structure for the curved photovoltaic tiles on both sides through arc-shaped support parts.

[0009] In some embodiments, the support assembly includes an arched support portion and a fixed beam, wherein the arched support portion is evenly distributed on the upper surface of the fixed beam, the arched support portion is located below the curved photovoltaic tile, and the top curvature of the arched support portion is greater than the top curvature of the curved photovoltaic tile.

[0010] By adopting the above technical solution, the arched support part provides auxiliary support at the gap below the curved photovoltaic tile, and at the same time, the large curvature top provides auxiliary support without affecting the offset angle support adjustment of the curved photovoltaic tile.

[0011] In some embodiments, the fixed cross beam and the bottom end of the curved base tile are movably fitted together, and a worm gear groove is embedded in the bottom end of the curved base tile. At the same time, an adjusting worm is provided at the fixed cross beam corresponding to the worm gear groove at the fitting position of the fixed cross beam and the curved base tile, and the worm gear groove and the adjusting worm constitute a worm gear transmission structure.

[0012] By adopting the above technical solution, the deflection displacement and support angle of the curved base tile can be adjusted through the worm gear tooth groove and the worm gear transmission structure of the adjustable worm, and the support height of the curved photovoltaic tile by the arc-shaped support parts on both sides can be changed, thereby adjusting the support angle of the curved photovoltaic tile, making it convenient to adjust the light-facing surface of the solar panel.

[0013] In some embodiments, a movable shaft is integrally provided inside the fixed crossbeam, and the movable shaft and the adjusting worm are an integrated structure, and the movable shaft and the adjusting worm as a whole form a synchronous drive structure through a single servo motor.

[0014] By adopting the above technical solution, multiple worm gear transmission structures can be directly and synchronously driven through the movable shaft, thereby facilitating synchronous adjustment of the curved photovoltaic tile array.

[0015] In some embodiments, the overlapping component at the curved base tile is a male overlapping portion, and a card joint is protrudingly provided above the male overlapping portion, and the card joint is a "T"-shaped structure;

[0016] The overlapping component at the protective frame is a female overlapping part, and a limited position clamping opening is arranged below the female overlapping part corresponding to the clamping joint.

[0017] In some embodiments, the lower end of the clamping joint is threadedly connected with a mounting bolt, and a movable through groove is provided on the surface of the male overlap portion corresponding to the position of the mounting bolt;

[0018] The mounting bolt passes through the movable through slot, and the clamping joint and the mounting bolt as a whole form a movable mounting adjustment structure at the movable through slot.

[0019] By adopting the above technical solution, the card joint can be adjusted within a certain range of installation activities through the installation structure of the mounting bolt and the movable through groove, so that sufficient activity space is reserved when the curved photovoltaic tile and the curved base tile are deflected and adjusted.

[0020] In some embodiments, elastic convex edges are provided on both sides of the limit snap-in, and the elastic convex edges are arc-shaped structures bent toward the inside of the limit snap-in, and the maximum gap of the limit snap-in is smaller than the maximum width of the clamping joint.

[0021] By adopting the above technical solution, when the clamping joint is overlapped at the limiting clamping mouth, the elastic convex edge can be squeezed and obliquely inserted into the limiting clamping mouth, and the narrow limiting clamping mouth cooperates with the elastic convex edge to effectively prevent the clamping joint from falling out.

[0022] In some embodiments, the roof photovoltaic structure further includes a cleaning pipe assembly, which is used for cleaning the surface of the curved photovoltaic tiles and the curved base tiles and for pressing down the curved base tiles for auxiliary limiting. The middle part of the bottom surface of the curved base tile is an arc-shaped guide groove, and the cleaning pipe assembly is attached to the surface of the arc-shaped guide groove, and the head and tail ends of the cleaning pipe assembly are fixed to the main hoop of the building roof;

[0023] The curved base tile as a whole forms a fitting deflection structure between the cleaning tube assembly and the supporting assembly.

[0024] In some embodiments, a fitting wiper is fixed to the lower surface of the cleaning tube assembly, and the fitting wiper is movably fitted to the upper surface of the arc-shaped guide groove.

[0025] By adopting the above technical solution, during the use of the device, the fitting wiper strip is movably fitted with the arc-shaped guide groove, so that when the curved base tile is movably adjusted, the fitting wiper strip can simultaneously wipe the bottom of the arc-shaped guide groove, effectively reducing the accumulation of dirt.

[0026] In some embodiments, cleaning nozzles are symmetrically arranged on the left and right sides of the cleaning tube assembly, and the cleaning nozzles are evenly distributed above the sides of the cleaning tube assembly, and the openings of the cleaning nozzles face the top of the curved photovoltaic tile.

[0027] By adopting the above technical solution, cleaning water can be connected to the cleaning pipe assembly, and the surface of the curved photovoltaic tiles can be sprayed and rinsed through the cleaning spray holes. While spraying, the curved photovoltaic tiles can be synchronously deflected to improve the cleaning effect over a large area.

[0028] In some embodiments, a permanent magnet is embedded in the upper surface of the support assembly, and an adsorption magnetic ring is sleeved on the surface of the cleaning tube assembly. The permanent magnet and the adsorption magnetic ring correspond to each other in upper and lower positions and are magnetically attracted to each other.

[0029] By adopting the above technical solution, further magnetic adsorption by permanent magnets and adsorption magnetic rings can facilitate the fitting of the wiper strip to the arc guide groove, and can also maintain the meshing state of the worm gear groove and the adjustment worm, thereby maintaining the stability of the overall structure.

[0030] Compared with the prior art, the beneficial effects of the present invention are: the roof photovoltaic structure facilitates the stable overlapping and laying of photovoltaic tiles, and can be used in conjunction with the movable overlapping structure for flexible support adjustment and cleaning and maintenance, thereby improving the working efficiency of photovoltaic tiles and facilitating long-term use. The technical details of the stable connection, efficient cleaning and flexible deflection support of the curved photovoltaic tiles together constitute its unique advantages. The specific structural advantages include:

[0031] 1. By utilizing the deflection support of the curved base tile's own arc-shaped structure, the overlapped components on both sides maintain the stable connection of the curved photovoltaic tile, thereby flexibly supporting and adjusting the curved photovoltaic tile. In combination with the worm gear grooves and the worm adjustment structure embedded in the curved base tile, it is convenient to adjust the sun-facing side and improve the operation efficiency.

[0032] 2. A cleaning pipe assembly is provided for use with curved photovoltaic tiles and curved base tiles. On the one hand, the cleaning pipe assembly fixes the curved base tiles. At the same time, the cleaning pipe assembly can wipe the arc-shaped guide grooves that are more likely to accumulate dirt by cooperating with the deflection of the curved base tiles through the fitting wiper strip. At the same time, the cleaning pipe assembly can also cooperate with the cleaning spray hole to spray and flush the curved photovoltaic tiles synchronously to carry out large-scale cleaning, which is convenient for equipment maintenance and long-term use;

[0033] 3. Flexible and stable overlap is achieved through the matching structure of the male overlap part and the female overlap part. The "T"-shaped card joint is not easy to fall out with the elastic convex edge. At the same time, the reserved activity space of the movable groove at the male overlap part and the activity margin brought by the elastic convex edge can also facilitate the flexible deflection of the curved photovoltaic tiles and the curved base tiles, while maintaining a stable connection.

[0034] These innovative designs not only improve the energy conversion efficiency and service life of photovoltaic tiles, but also provide new ideas for the integrated development of green buildings and renewable energy. BRIEF DESCRIPTION OF THE DRAWINGS
