As solar energy is increasingly used, portable installation and disassembly of photovoltaic tiles in photovoltaic systems is becoming more and more important. Because of the current design of most photovoltaic tile roofing or wall systems, solar panels are intended to be laid directly on ceramic tiles or other conventional tiles or to combine solar technology with the manufacture of tiles of other materials.
The above-described installation naturally achieves the goal of green power generation, but unfortunately it tends to be at the expense of the overall aesthetics of the building. More importantly, the integrated design makes the solar module difficult to disassemble and maintain independently, adds complexity and cost burden to future operation and maintenance work in an intangible way, and fails to reduce the redundant use of building materials to the maximum extent. Therefore, this integration still fails to provide flexibility in the independent disassembly of the solar energy sections, limiting the ease of system upgrades or replacement.

This patent has improved photovoltaic roofing system's photovoltaic tile's dismouting efficiency, reduces installation cost to improve photovoltaic roofing system's water-proof effects.

Meanwhile, the waterproof effect of the joints is achieved only through the I-shaped slots, the waterproof effect of the joints can only achieve the waterproof effect of the surfaces, and the influence of joint water seepage on the photovoltaic system is not considered.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example 1
Referring to fig. 1-10, a photovoltaic system for facilitating disassembly and assembly of a photovoltaic tile includes:
A photovoltaic module 1 for converting light energy into electrical energy;
a keel assembly 2 for securing the photovoltaic module 1;
The plurality of hook pieces 3 are used for overlapping the photovoltaic module 1 on the keel module 2 in a staggered manner through clamping and hanging effects, so that the photovoltaic module 1 can be conveniently disassembled and assembled, and the plurality of hook pieces 3 are fixed on the keel module 2 at intervals;
the water guide component 4 is used for discharging water leaked between the photovoltaic components 1, and adjacent photovoltaic components 1 positioned on the same layer are lapped on the water guide component 4;
and the sealing piece 5 is clamped between the hook piece 3 and the photovoltaic module 1.
In the embodiment, the plurality of hook pieces 3 are arranged on the keel assembly 2 at intervals, so that the photovoltaic assembly 1 is convenient to detach and install under the clamping action of the upper hook pieces 3 and the hanging action of the lower hook pieces 3; meanwhile, the water guide assembly 4 is arranged between the adjacent photovoltaic tiles 11, so that water possibly penetrating into the joint between the adjacent photovoltaic tiles 11 can be discharged from the water guide assembly 4, and the longitudinal waterproof effect of the photovoltaic tiles 11 is ensured; the sealing piece 5 is arranged between the hook piece 3 and the photovoltaic module 1, and when the photovoltaic module 1 is pressed on the sealing piece 5, a good sealing effect is formed between the hook piece 3 and the photovoltaic module 1, so that the transverse waterproof effect of the photovoltaic tile 11 is ensured.
It should be noted that, in the embodiment, the staggered lap joint of the photovoltaic modules 1 may be understood as the up-down lap joint of the adjacent photovoltaic modules 1, that is, the lower part of the upper photovoltaic module 1 is lapped on the upper part of the lower photovoltaic module 1; by staggered, it is meant that at least the seams of adjacent layers of photovoltaic modules 1 are staggered with respect to each other, as shown in fig. 2.
As shown in fig. 14, the photovoltaic module 1 in this embodiment includes photovoltaic tiles 11, and a plurality of photovoltaic tiles 11 are connected to an inverter through connection terminals 12 and connection wires 13 provided on the back surface.
It should be noted that, the photovoltaic tile 11 mainly includes toughened photovoltaic glass, an upper layer POE film, a monocrystalline silicon cell, a lower layer POE film, an isolation insulating layer and a metal bottom plate which are sequentially arranged from top to bottom. It is obvious that the photovoltaic tile 11 can also be replaced with a partial structure according to the implementation needs. For example, to increase the colority of the photovoltaic tile 11, the tempered photovoltaic glass may be replaced with a colored glass plate; in order to integrate with other non-power-generation tiles 9 of the slate tile roof, the toughened photovoltaic glass can be replaced by slate-like toughened photovoltaic glass. The connection relation and the working principle of each part of the photovoltaic module 1 belong to the prior art, and the application is not repeated here.
Referring to fig. 3-6, the water guiding assembly 4 in this embodiment includes a water guiding plate 41, a partition plate 42 is vertically disposed in the center of the water guiding plate 41 along the length direction thereof, a first support plate 43 and a second support plate 44 are disposed in parallel on two sides of the partition plate 42 at intervals, and the first support plate 43 and the second support plate 44 are respectively used for supporting two ends of adjacent photovoltaic modules 1 close to each other;
A first water guide channel 45 is formed between the first support plate 43 and the partition plate 42, a second water guide channel 46 is formed between the second support plate 44 and the partition plate 42, and a sealing structure 47 is arranged between the first water guide channel 45 and the second water guide channel 46 along the length direction; when the photovoltaic module 1 is pressed on the sealing structure 47, the sealing structure 47 divides the first water guiding channel 45 and the second water guiding channel 46 into a first water guiding main channel 451 and a first water guiding sub channel 452, and a second water guiding main channel 461 and a second water guiding sub channel 462, which are independent and not communicated with each other, respectively.
The water guide plate 41 is an aluminum alloy plate with two middle horizontal sides bent upward, and the photovoltaic tiles 11 are respectively overlapped on two sides of the partition plate 42, i.e. the upper parts of the first water guide channel 45 and the second water guide channel 46. In general, rain water may penetrate from the seams of adjacent photovoltaic tiles 11 into the first water guiding main channels 451 and/or the second water guiding main channels 461 located on both sides of the separation plate 42. Due to the sealing structure 47, mutually independent spaces are formed between the first water guiding main channel 451 and the second water guiding sub-channel 462 and between the second water guiding main channel 461 and the second water guiding sub-channel 462, so that rainwater can only be discharged along the inclined first water guiding main channel 451 and/or second water guiding main channel 461, thereby ensuring the longitudinal waterproof effect of the photovoltaic tile 11.
In view of the extreme situation that the first water guiding main channel 451 and/or the second water guiding main channel 461 is blocked or excessively large in water, and at the same time, when the sealing structure 47 is partly damaged for water penetration, part of the rain water that passes over the sealing structure 47 from the first water guiding main channel 451 and/or the second water guiding main channel 461 can still be discharged from the channel 452 and/or the second water guiding main channel 462 through the inclined first water guiding. Thus, the sealing structure 47 has double water-blocking effect, and the longitudinal water-blocking effect of the photovoltaic tile 11 is improved.
Referring to fig. 6, in order to improve the sealing performance of the sealing structure 47, in this embodiment, the sealing structure 47 includes a D-shaped hollow sealing strip 471, a horizontal portion of the D-shaped hollow sealing strip 471 is fixed to the upper surface of the water guiding plate 41, and a plurality of elastic reinforcing strips 472 for enhancing the sealing performance with the photovoltaic module 1 are disposed along the length direction of the outer periphery of the arc portion of the D-shaped hollow sealing strip 471.
Specifically, when the photovoltaic module 1 is pressed on the D-shaped hollow sealing strip 471, the sealing structure 47 is deformed by the pressure, and under the elastic force of the hollow sealing strip, the plurality of reinforcing strips 472 are pushed to the lower surface of the sealing strip, so that the plurality of reinforcing strips 472 are in elastic contact with the photovoltaic module 1. Elastic contact is understood here to mean contact with a pressure such that a multiple seal is formed between the reinforcing strip 472 and the photovoltaic module 1. The sealing structure 47 in this embodiment is made of rubber.
Referring to fig. 4 and 5, the partition plate 42 is higher than the first support plate 43 and the second support plate 44 with the same height, and when the photovoltaic module 1 is pressed on the sealing structure 47, the upper surface of the partition plate is flush with the upper surface of the partition plate 42.
It will be appreciated that, in order to provide a good seal between the separator 42 and the photovoltaic tiles 11 on both sides, waterproof sealing strips may be attached to both sides of the separator 42. Under the extrusion of photovoltaic tiles 11 on two sides, the waterproof sealing strip has better waterproof performance between the partition plate 42 and the photovoltaic tiles 11, and rainwater is prevented from entering from seams. Thereby further improving the longitudinal waterproof effect of the photovoltaic tile 11. Considering that the waterproof sealing strip needs to be exposed to sunlight, in this embodiment, the waterproof sealing strip may be made of silicone rubber. The silicone rubber has excellent high temperature resistance and weather resistance, is suitable for sealing the photovoltaic tile 11 exposed to strong sunlight for a long time, and can effectively prevent moisture invasion and maintain long-term stable performance.
Further, the upper parts of the first support plate 43 and the second support plate 44 in this embodiment may be provided with sealing strips for improving the sealing property with the photovoltaic module 1.
Referring to fig. 7, in order to improve the waterproof performance of the photovoltaic tile 11 in the lateral direction, the sealing member 5 in this embodiment is a sealing rubber strip, and the sealing rubber strip is disposed on the upper surface of the upper portion of the photovoltaic tile 11.
Specifically, when the adjacent photovoltaic tiles 11 overlap each other, the pressure of the upper photovoltaic tile 11 is set at the upper portion of the lower photovoltaic tile 11, so that the pressure is applied to the sealing rubber strip located at the upper portion of the lower photovoltaic tile 11, and the sealing rubber strip is elastically contacted with the lower surface of the lower portion of the photovoltaic tile 11. At this time, a good sealing effect is formed between the sealing rubber strip and the upper layer photovoltaic tile 11, and the photovoltaic tile 11 can be effectively prevented from entering into the transverse rainwater, so that the transverse waterproof effect of the photovoltaic tile 11 is ensured.
Referring to fig. 8, 9 and 10, in this embodiment, the hanger 3 includes a hanging portion 31 and a supporting portion 32, a clamping space 33 for accommodating the photovoltaic module 1 is formed between the hanging portion 31 and the supporting portion 32, a mounting hole 321 for fixing with the keel assembly 2 is formed at the upper portion of the supporting portion 32, a through hole 311 concentric with the mounting hole 321 and having a diameter larger than that of the mounting hole 321 is formed in the hanging portion 31, and a fastener for fitting the mounting tool in the mounting hole 321 is formed in the through hole 311;
The lower part of the supporting part 32 is provided with an elastic part 34 for providing elastic support to the photovoltaic module 1, the lower part of the hanging part 31 is provided with a bending part 35, and the bending part 35 and the hanging part 31 form a hanging space 36 for hanging the photovoltaic module 1 at a side far from the supporting part 32.
Specifically, the hook member 3 in the above embodiment is generally U-shaped, and the hanging portion 31 and the supporting portion 32 are respectively two parallel sides of the U-shape. The clamping space 33 is used for pressing the upper part of the photovoltaic tile 11 positioned in the clamping space through the elastic part 34 of the upper layer hook piece 3 and limiting and hanging the lower part of the photovoltaic tile 11 in cooperation with the hanging part 31. It will be appreciated that when the photovoltaic tile 11 is suspended on the hanger 3, it will exert a downward force on the suspension portion 31 due to gravity, thereby further compacting the photovoltaic tile 11 located in the clamping space 33, improving the stability of the suspension of the photovoltaic tile 11.
Referring to fig. 1 and 2, the keel assembly 2 in this embodiment includes a plurality of transverse keels 21 arranged in parallel at intervals for fixing the hook members 3, and a plurality of longitudinal keels 22 arranged in parallel with each other are vertically fixed at intervals at the lower part of the transverse keels 21.
Specifically, the transverse keels 21 and the longitudinal keels 22 are square stainless steel pipes. To enhance the service life of the transverse keels 21 and the longitudinal keels 22, the stainless steel tube may be galvanized or sprayed to enhance its corrosion resistance and weather resistance. Meanwhile, a sun-proof layer can be coated on the surface of the stainless steel for sun-proof treatment, so that oxidation reaction caused by ultraviolet rays and high temperature can be effectively resisted, and the service life of the keel assembly 2 is prolonged.

The mounting position of the corner brace 6 needs to determine the lateral distance between the corner brace 6 according to the length of the lateral keel 21, and determine the longitudinal distance between the upper and lower corner brace 6 according to the length of the longitudinal keel 22. To enhance the overall securement of the keel assembly 2, each longitudinal keel 22 is secured to the structural layer 8 by expansion bolts 7 at the corner bracket 6.
S2, fixing the corner bracket 6 and the longitudinal keel 22 in a welding or detachable fastening mode, and leveling; the fastening mode can be bolt fastening.
It will be appreciated that the purpose of the longitudinal runners 22 being installed and leveled is to enhance their flatness, thereby ensuring that the transverse runners 21 installed thereon have a better flatness, enhancing the overall stability and support capacity of the runner assembly 2. So, not only be convenient for the installation of photovoltaic module 1, can guarantee moreover that the roughness of photovoltaic module 1 after the installation is high, the phenomenon of unevenness can not appear.

When the width of the roof of the sunny side roof is an integral multiple of the photovoltaic tile, the photovoltaic tile is paved on the roof; i.e. only the photovoltaic tiles 11 are suspended from the keel assembly.
When the width of the roof of the sunny side roof is not an integral multiple of the photovoltaic tile 11, the photovoltaic tile 11 is matched with the non-power generation metal tile 10 which is convenient to cut, so that the width of the roof is adapted.
Specifically, as in the roof of fig. 13, there are triangles, parallelograms and trapezoids due to the roof. When the width of the roof is not an integer multiple of the photovoltaic tiles 11, first, the shape of the keel assembly needs to be adjusted according to the size of the roof to adapt to the shape of the roof. Secondly, the corner of the roof needs to be filled by cutting the non-power-generating metal tiles 10 on at least one side of the roof, and the roof is hung on the transverse keels 21 through the hook pieces 3. At this time, the keel assembly 1 of the photovoltaic system is laid with the photovoltaic tiles 11 and the non-power generating metal tiles 10.
Meanwhile, considering the heat dissipation of the photovoltaic system, the cornice with ventilation effect is adopted at the cornice in the embodiment. In particular, the cornice may be a metal plate with a number of vents or barrier-type slits.
In addition, referring to fig. 15, the photovoltaic system of the present application may be connected to an energy storage device through an inverter, so as to store the electric energy converted from the light energy, which is convenient for use at night. Of course, the inverter may also be connected to the grid or to the consumer load. Meanwhile, intelligent control and monitoring can be realized through the association of network control and an intelligent management platform.
According to the photovoltaic module, the plurality of hook pieces 3 are arranged on the keel assembly 2 at intervals, and the photovoltaic assembly 1 is convenient to independently detach and install under the clamping action of the upper hook pieces 3 and the hanging action of the lower hook pieces 3; meanwhile, the water guide assembly 4 is arranged between the adjacent photovoltaic tiles 11, so that water possibly penetrating into the joint between the adjacent photovoltaic tiles 11 can be discharged from the water guide assembly 4, and the longitudinal waterproof effect of the photovoltaic tiles 11 is ensured. Meanwhile, the roof space is fully utilized, the aesthetic degree of the building is guaranteed, the utilization rate of light energy is improved, and the traditional energy is effectively saved.
While the foregoing is directed to embodiments of the present application, it will be appreciated by those skilled in the art that various modifications and changes can be made without departing from the principles of the present application, and such modifications and changes should be considered as being within the scope of the present application.
