Description

Integrated power generation building material support system and installation method of power generation building material

Technical Field

The present invention relates to the photovoltaic field, and specifically to an integrated power generation building material support system and a power generation building material installation method.

Background Art

With the growing global demand for clean energy, solar photovoltaic power generation technology has developed rapidly. Photovoltaic tiles, as a product that embeds photovoltaic cells into building materials, combine solar power generation with architectural aesthetics and have become an indispensable part of modern architecture. Traditional photovoltaic panels are often independent of buildings, while photovoltaic tiles directly replace traditional roof tiles or building facades, achieving a perfect fusion of energy production and building functions. Building integrated photovoltaics (BIPV) is an emerging design concept in recent years. Its core is to integrate photovoltaic modules as part of the building rather than simply attaching them to the surface of the building. This design can not only generate clean energy, but also improve the appearance, thermal performance and acoustic properties of the building, while reducing building energy consumption and improving energy efficiency.

In the process of photovoltaic building integration installation, the bracket system is more important; however, the traditional bracket system cannot solve the problem of photovoltaic integration into the building. It simply attaches photovoltaics to the outer layer of the building, causing safety hazards. At the same time, the stability and safety of the photovoltaic system depend to a large extent on the design and quality of the bracket system. Traditional bracket systems mostly adopt fixed or adjustable angle designs, but the installation process is complicated. In addition, the installation of traditional bracket systems is complicated. Each photovoltaic module requires a large number of brackets and fasteners, and the number of screws alone is as many as more than 10, making it difficult to install the roof and facade of the building. And if too many screws are used, there will be more leaks, which is more likely to cause water seepage. In addition, if there is a screw hole in the photovoltaic tile, the photovoltaic tile will be damaged around the screw hole, thereby reducing the service life of the photovoltaic tile.

Summary of the invention

Therefore, in order to solve the above-mentioned shortcomings, the present invention provides an integrated power generation building material support system and a power generation building material installation method.

DETAILED DESCRIPTION

Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

As described in the background technology, the support system is more important in the process of photovoltaic building integration installation; however, the traditional support system cannot solve the problem of photovoltaic integration into the building, but simply attaches the photovoltaic to the outer layer of the building, causing safety hazards. At the same time, the stability and safety of the photovoltaic system depend to a large extent on the design and quality of the support system. Traditional support systems mostly adopt fixed or adjustable angle designs, but the installation process is complicated, and often requires working at heights, which poses certain safety risks. In addition, the installation of traditional support systems is complicated. Each photovoltaic module requires a large number of supports and fasteners, and the number of fastening screws alone is as many as more than 10 times, making it difficult to install the roof and facade of the building; and if too many screws are used, there will be more leaks, which will easily cause water seepage. Moreover, if a screw hole appears in the photovoltaic tile, the photovoltaic tile will be damaged around the screw hole, thereby reducing the service life of the photovoltaic tile.

Based on the above reasons, this embodiment provides an integrated power generation building material support system. As shown in FIG. 1 to FIG. 8 , the integrated power generation building material support system includes a support member 100 and a connector 300.

The support member 100 is installed on a working surface (the working surface is the installation surface where the flat photovoltaic tile needs to be installed, such as a roof or a wall) along the longitudinal direction of the flat photovoltaic tile 600. As shown in FIG4 , the support member 100 includes two vertical vertical affixed portions 101, and a horizontal support portion 102 extending along the lateral direction of the flat photovoltaic tile 600 is provided on the outer side of the vertical affixed portions;

A connector 300 is mounted on each of the horizontal supporting parts and is fitted with the vertical fitting part. The connector is provided with a mounting groove 302, which extends along the longitudinal direction of the flat photovoltaic tile. The opening direction of the mounting groove 302 is parallel to the horizontal supporting part.

The bottom of the connector 300 has a contact portion 301 in contact with the horizontal support portion, and there is a gap between the contact portion and the mounting groove 302. The contact portion is plate-shaped. The gap allows the photovoltaic tile to be installed at a distance from the working surface, making it convenient to install the junction box 700 and lead wires at the bottom of the flat photovoltaic tile.

The above technical features can realize the fast and stable installation of the flat photovoltaic tiles, and the connection with the work surface can be realized through the support members, providing support points for the flat photovoltaic tiles; the connecting members can be first installed on the flat photovoltaic tiles when installing the flat photovoltaic tiles, and the connecting members are combined with the flat photovoltaic tiles in the form of card slots, and the installation is fast and convenient. In order to provide installation stability and sealing, structural adhesive can be applied during the engagement; the flat photovoltaic tiles installed with the connecting members are then installed on the support members. During installation, the connecting members are in contact with the vertical fitting parts and the horizontal supporting parts of the supporting members, and the flat photovoltaic tiles are supported by the horizontal supporting parts, which is also convenient for leveling the flat photovoltaic tiles, and the vertical fitting parts can realize the limiting of the connecting members, and the places where the vertical fitting parts and the horizontal supporting parts contact the connecting members are fixed and sealed by structural adhesive, and the whole In the whole process, the flat photovoltaic tiles and the connectors are fixed by snapping and bonding. No screws are used on the flat photovoltaic tiles, which should not affect any sealing performance of the flat photovoltaic tiles. In particular, no screws or screw holes will appear on the end faces or exposed surfaces, and the service life of the flat photovoltaic tiles will not be reduced due to installation. In addition, the use of connectors and supports is convenient and quick to install, and can avoid the problem of traditional brackets using many screws for installation. Because after installation with screws, screw holes will appear, especially exposed screws, which must be waterproofed. Regardless of whether it is a steel structure or a photovoltaic tile, if a screw hole appears, the steel structure or the photovoltaic tile will seep or be damaged from the screw hole, and will also spread around with the screw hole as the center, thereby reducing the life of the entire power generation building material bracket or photovoltaic tile.

At the same time, in the above-mentioned technical features, the bottom of the connecting member 300 has a contact portion 301 in contact with the horizontal support portion, and the contact portion is plate-shaped; and a rough portion is opened on the contact portion or the horizontal support portion, and the rough portion is formed by a number of convex ridges; wherein the plate-shaped contact portion and the horizontal support portion structure can increase the contact area, improve the support, and also increase the bonding area; after increasing the contact area, even if there is a little water leakage on the upper part, the path of water travel can be extended by the large contact area, thereby improving the water blocking effect and the waterproof effect; and the rough portion is formed by a number of convex ridges, and the direction of the convex ridges extends along the longitudinal direction of the flat photovoltaic tile, such a rough portion can increase the contact area of the structural adhesive and improve the bonding and sealing effects; as mentioned above, even if there is a leakage point on the upper part, a number of convex ridges can improve the water blocking effect, and adjacent convex ridges can also form a longitudinal drainage channel, and can also achieve longitudinal drainage, thereby preventing water from entering the bottom of the photovoltaic tile downward, thereby improving the waterproof effect.

In order to improve the connection stability and sealing between the connecting member and the supporting member, in one embodiment, the contact surfaces of the supporting member 100 and the connecting member 300 are fixed and sealed by bonding. For example, as shown in Figures 12 and 13, the vertical fitting part and the horizontal supporting part are fixed and sealed at the contact points with the connecting member by using structural adhesive 900.

The above-mentioned technical features can solve the problems of sealing stability and connection stability at the existing connection points, and prevent water from entering under the photovoltaic tiles, thereby affecting the wiring and line problems below.

In order to facilitate the lead-out of the wires, in one embodiment, a wire groove 103 with an upper opening is formed in the gap between the two vertical fitting parts 101, and a lead-in hole 105 is opened at the bottom of the wire groove 103. The wire groove can realize side lead-out (i.e., from the side of the photovoltaic tile, and the line can be arranged longitudinally along the photovoltaic tile), and the lead-out hole can realize the lead-out of the photovoltaic tile wire 800 from the bottom into the wire groove to avoid the risk of the wire contacting with water, because if the photovoltaic tile leads out from the top, it is not convenient to waterproof, and it is easy to have leakage points and water seepage.

In order to protect the cable trough and prevent water from entering the cable trough, in one embodiment, a protective cover plate 200 is installed at the open end of the cable trough. The protective cover plate is installed by snapping together, which is quick and convenient, and overcomes the risk of water leakage caused by installation through self-tapping screws.

For example, as shown in Fig. 17, the upper end of the vertical fitting portion 101 has a first protrusion 106, and the lower end surface of the protective cover plate 200 has a second protrusion 202 opposite to the first protrusion 106, and the first protrusion is buckled with the second protrusion. Through the cooperation of the two protrusions, the protective cover plate and the support member can be snapped together, and through the protrusions, an S-shaped contact path can be formed at the contact point to reduce the risk of rainwater entering the cable trough.

Exemplarily, as shown in FIG18, two engaging grooves 201 adapted to the vertical fitting portion are formed on the inner side of the protective cover plate, and the outer side of the vertical fitting portion is engaged with the engaging groove by a serrated portion. The serrated engagement can prevent the protective cover plate from falling off and ensure the stability of the engagement. The serrated engagement can increase the contact area. After increasing the contact area, adding structural adhesive can improve the tightness of the connection. At the same time, multiple S-shaped contact paths can be formed by the serrated engagement to reduce the risk of rainwater entering the cable trough.

In order to improve the connection stability and waterproofness, the outer surface of the horizontal support part 102 and the vertical fitting part 101 has a rough part, which fits the connecting piece, and the rough part is formed by a rough surface or a plurality of strip grooves. Such a rough part can increase the contact area of the structural adhesive and improve the bonding and sealing effect; as mentioned above, even if there is water leakage on the top, the plurality of convex ridges can improve the water blocking effect, and the adjacent convex ridges can form a longitudinal drainage channel, and can also achieve longitudinal drainage, thereby preventing water from entering the bottom of the photovoltaic tile downward, thereby improving the waterproof effect.

In order to better install the support member, in one embodiment, as shown in FIG. 13 , the support member 101 is fixed to the purlin of the working surface by fasteners.

When installing support members on an old roof, in order to reduce damage to the roof, as shown in Figures 2 and 12, the support member 101 is supported on the working surface by a π-shaped support block 400 at the bottom, the support member 100 is connected to the π-shaped support block by fasteners, and the π-shaped support block is connected to the working surface by fasteners; exemplarily, the fasteners are self-tapping screws.

In order to better drive the self-tapping screws into the support member, in one embodiment, a fastener positioning portion 104 is provided on the inner side surface of the vertical fitting portion 101 and/or the bottom surface of the wire groove. The fastener positioning portion is formed by two parallel ridges, and the purpose is to reduce the deviation of the self-tapping screw when the self-tapping screw is driven in.

In order to improve the support of the flat photovoltaic tile, as shown in FIG. 1 and FIG. 16, in one embodiment, the integrated power generation building material support system further includes a transverse support block 500, which is supported on the transverse end surface of the flat photovoltaic tile and connected to the horizontal support portion of the support member. As shown in FIG. 16, adjacent flat photovoltaic tiles can be supported by two transverse support blocks, and the two adjacent transverse support blocks are arranged back to back and fixed by structural adhesive 900 between the contacts. The upper end surface of the transverse support block is not higher than the upper surface of the flat photovoltaic tile (as shown in FIG. 20). The transverse support block can solve the problem of the power generation building material support being higher than the glass surface under the premise of improving the support strength, and solves the problem of dust accumulation at the connection between power generation building materials (as shown in FIG. 19, in order to ensure the support strength, the upper end surface of the traditional support block is higher than the upper surface of the photovoltaic panel, and a lot of dust 901 is easily accumulated in places with height differences); thereby forming the rainwater self-cleaning function of the roof.

In another embodiment, a method for installing power generation building materials is provided, which is installed by using the integrated power generation building material support system. The installation method includes:

The support member is directly installed on a working surface by means of fasteners (self-tapping screws) or by means of π-shaped support blocks; the working surface is a roof or a wall;

Adjust the horizontality of the support according to the roof inclination or the direction of water flow on the roof;

Installing connectors and/or lateral support blocks on the flat photovoltaic tiles, wherein the flat photovoltaic tiles are installed in the installation grooves by snap-fitting and filled with sealant;

Installing the flat photovoltaic tile with the connector on the support, wherein the vertical fitting portion and the horizontal supporting portion of the connector are in contact with the connector, and the contact surface is fixed by a sealant;

Lead the wires of the junction box on the lower end of the flat photovoltaic tile into the wire slot from the lead hole, and connect the positive and negative lines;

Close the upper cover of the wire slot and install the protective cover by snapping it in place.

A bridge is installed on the working surface to span the flat-panel photovoltaics.

For example, when installing the bracket system on a new building structure (instead of installing color steel tiles and other building roofing materials), the support is fixed vertically to the building roof purlin and fastened with stainless steel self-tapping screws or screws. The spacing between adjacent support members is calculated in advance, and the spacing is equal to the width required for the flat photovoltaic tile to be fixed with the connector.

For example, when installing a bracket system on the roof of an old building, it is necessary to calculate in advance the distance between adjacent supports. The distance is equal to the width required for fixing the flat photovoltaic tiles with connectors, and π-shaped support blocks are installed in advance below the distance between the supports.

Measure the roof level again, select π-shaped support blocks of different models and sizes on the roof according to the level difference, fix the π-shaped support blocks to the roof, and basically keep the raised part of the π-shaped support blocks and the raised part of the original tiles on the roof in the same plane, and the error should not exceed 3cm.

When the place where the π-shaped support block needs to be installed conflicts with the original roof bulge, a widened π-shaped support block can be used.

The fixed support piece is installed on the π-shaped support block and fastened with stainless steel self-tapping screws or screws.

Whether it is a new building structure or an old building rooftop installation of flat photovoltaic tiles, the installation method of flat photovoltaic tiles is the same, as follows:

Installation method 1: Install the left and right sides of a row of flat photovoltaic tiles in the installation groove of the connector in turn, fix them with sealant, install horizontal support blocks on the upper and lower adjacent edges of two adjacent flat photovoltaic tiles, and fill them with sealant. Fix the left and right horizontal support blocks of the installed row of flat photovoltaic tiles on the two support pieces respectively with structural silicone.

Installation method 2: Install the left and right sides of a flat photovoltaic tile in the slots of the connector in turn and fix them with sealant; install horizontal support blocks on the upper and lower sides respectively and fix them with sealant. Fix the left and right horizontal support blocks of multiple flat photovoltaic tiles on the two support pieces in turn with structural silicone.

According to the position of the junction box of the flat-plate photovoltaic tile, a hole is opened at the bottom of the wire groove of the support. The hole diameter is large enough to pass the MC4 head. The positive and negative MC4 heads of the flat-plate photovoltaic tile and the positive and negative DC lines are inserted into the profile groove through the hole in the middle part of the support, and connected to the DC line through the MC4 head in the groove.

Place the protective cover on the wire duct of the support to complete the installation.

Optionally, if there is a need to enhance the structural strength and pull-out resistance, nails can be driven obliquely into the support wire trough to fix the connector to enhance the connection strength.

Optionally, the supporting corridor panels can be mounted on the supports during installation and maintenance without stepping on the flat photovoltaic tiles.

Optionally, flat photovoltaic tiles can be selected in different sizes according to the actual area of the roof, or the same general size can be used for a large area, and when the remaining width or length at the edge of the roof is insufficient, another suitable small-sized flat photovoltaic tile can be installed to achieve maximum area utilization of photovoltaic power generation.

Optionally, the flat photovoltaic tiles can also be installed on the wall through the power generation building material support system shown, and the flat photovoltaic tiles can be used as photovoltaic wall panels.

The present invention integrates photovoltaic tiles with buildings, which not only provides clean energy, but also improves the exterior design of the building, making it more modern and environmentally friendly. By improving the power generation building material support system, the installation cost and time are reduced. The innovative installation method and modular design (such as support parts and connectors) greatly simplify the construction process, reduce labor requirements, reduce installation costs, and shorten the project completion cycle.

Exemplarily, the flat photovoltaic tile is rectangular, with a length and width limited to 30cm-300cm. The flat photovoltaic tile is composed of: a surface light-transmitting material, an upper hot-melt adhesive material, a solar cell power generation layer, a lower hot-melt adhesive material, and a reinforcing support layer from top to bottom.

The surface light-transmitting material is one or more materials selected from photovoltaic glass, photovoltaic soft glass, glazed colored glass, ETFE composite film, PET composite film, PVDF composite film, etc., which can receive sunlight, transmit light, and protect the internal solar cells.

The upper hot melt adhesive material is one or more of EVA (ethylene-vinyl acetate copolymer), POE (Polyolefin Elastomer), PVB (polyvinyl butyral), and silica gel, and is used to protect the solar cell circuit and bond the light-transmitting layer to the battery cell.

The solar cell power generation layer is one or more of a single crystal solar cell, a polycrystalline silicon solar cell, a cadmium telluride solar cell, and a perovskite solar cell, and adopts a series-parallel circuit to realize the orderly formation and output of photovoltaic current and voltage.

The lower hot melt adhesive material is EVA (ethylene-vinyl acetate copolymer), POE (Polyolefin Elastomer), PVB (polyvinyl butyral), one or more of the silicone rubbers, used to protect the solar cell circuit and bond the insulating protective layer.

The reinforced support layer is made of 0.25-2.5 thick metal plates, such as galvanized steel plates, aluminum plates, aluminum alloy plates, titanium alloy plates, and a pre-composite insulating layer on the surface layer, which is used as a photovoltaic tile on the surface layer of a lightweight roof. Or a 2-10mm composite plate with high strength and insulation and weather resistance, such as basalt plates, fire-resistant plates, tiles, cement plates, terrazzo plates, artificial plates, composite honeycomb plates, etc., is used as a walkable load-bearing roof photovoltaic tile.

The reinforcing support layer has two openings, and a junction box is bonded below the openings. The positive and negative electrodes of the solar cell power generation layer are led out from the openings and welded to the DC line in the junction box. The other end of the DC line is connected to an MC4 terminal. (That is, one photovoltaic tile has 1 positive junction box, 1 positive DC line, 1 positive MC4 terminal and 1 negative junction box, 1 negative DC line, and 1 negative MC4 terminal).

The above flat photovoltaic tile design can more efficiently convert solar energy into electrical energy, increase energy output, and reduce energy loss. Enhance the aesthetics and functionality of the building. The integration of photovoltaic tiles with the building not only provides clean energy, but also improves the exterior design of the building, making it more modern and environmentally friendly.
