Description
Technical Field
The invention relates to the technical field of roof photovoltaic modules, in particular to a photovoltaic system and a photovoltaic building convenient for dismounting and mounting photovoltaic tiles.
Background
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.
The patent application number is CN201920597546.8, a photovoltaic roofing system is disclosed, which comprises a keel and a plurality of photovoltaic tiles which are arranged on the keel, are vertically lapped and assembled left and right, and a clamping groove piece is respectively clamped at the left side and the right side of a power generation body of the photovoltaic tile; the photovoltaic roofing system further comprises: the H-shaped slot pieces are arranged between the left photovoltaic tile and the right photovoltaic tile, and the two clamping slot pieces which are close to each other of the left photovoltaic tile and the right photovoltaic tile are correspondingly inserted into the two slots of the H-shaped slot pieces. 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. However, when the photovoltaic tile at the center needs to be replaced, the photovoltaic tile to be replaced still needs to be replaced after the other related photovoltaic tiles in the same column or row are removed. Therefore, the independent disassembly and assembly of the photovoltaic tiles are not completely realized, and the convenient and independent replacement is not realized. 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.
