Description

Technical Field

[0001] The present invention relates to the technical field of roof photovoltaic modules, and in particular to a photovoltaic system and a photovoltaic building that are convenient for disassembly and assembly of photovoltaic tiles. Background Art

[0002] With the increasing use of solar energy, the portable installation and removal of photovoltaic tiles in photovoltaic systems are gaining more and more attention. At present, most photovoltaic tile roof or wall system designs tend to lay solar panels directly on ceramic tiles or other traditional tile materials, or combine solar technology with other tile materials.

[0003] While this installation method achieves the goal of green power generation, it unfortunately often comes at the expense of the building's overall aesthetics. More critically, this integrated design makes it difficult to disassemble and maintain the solar panels individually, adding complexity and cost to future operations and maintenance, while also failing to minimize redundant building materials. Consequently, this integration approach still lacks the flexibility to disassemble the solar components independently, limiting the ease of system upgrades or replacements.

[0004] Patent application number CN201920597546.8 discloses a photovoltaic roofing system comprising a keel and a plurality of photovoltaic tiles mounted on the keel and arranged in a stacked arrangement. Each of the photovoltaic tiles has a slot member mounted on each side of the power generating body. The photovoltaic roofing system also includes an I-shaped slot member disposed between two adjacent photovoltaic tiles, with the adjacent slot members of the two adjacent photovoltaic tiles correspondingly inserted into the two slots of the I-shaped slot member. This patent improves the installation and removal efficiency of the photovoltaic tiles in the photovoltaic roofing system, reduces installation costs, and enhances the waterproofing of the photovoltaic roofing system. However, when a central photovoltaic tile needs to be replaced, the other related photovoltaic tiles in the same column or row must be removed before the replacement tile can be replaced. Therefore, this patent does not fully implement the independent installation and removal of the photovoltaic tiles, nor does it allow for convenient and independent replacement. Furthermore, this patent only uses the I-shaped slots to provide seam waterproofing, which only provides a superficial waterproofing effect and does not consider the impact of water seepage from the seams on the photovoltaic system. Summary of the Invention

[0005] In order to solve at least one of the above technical problems, the present invention proposes a photovoltaic system and photovoltaic building that are easy to disassemble and assemble photovoltaic tiles. It can not only solve the problem of independent and convenient disassembly and assembly of photovoltaic components, but also effectively improve the waterproof effect between photovoltaic components, make full use of the roof space, ensure the beauty of the building, and improve the utilization rate of light energy, effectively saving traditional energy.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. The present invention arranges a number of hook members at intervals on the keel assembly, and under the clamping action of the upper hook member and the hanging action of the lower hook member, the photovoltaic assembly is easy to disassemble and install independently; at the same time, a water guide assembly is arranged between adjacent photovoltaic tiles, so that water that may seep into the gaps between adjacent photovoltaic tiles can be discharged from the water guide assembly, ensuring that the photovoltaic tiles have a waterproof effect in the longitudinal direction; a sealing member is arranged between the hook member and the photovoltaic assembly, and when the photovoltaic assembly is pressed on the sealing member, a good sealing effect is formed between the two, thereby ensuring the lateral waterproof effect of the photovoltaic tiles.

[0035] 3. The present invention provides a sealing structure. When the photovoltaic module is pressed against the D-shaped hollow sealing strip, the entire sealing structure is deformed by the pressure. Under the elastic force of the hollow sealing strip, the multiple reinforcement strips are tightly pushed against the lower surface of the sealing strip, making elastic contact between the multiple reinforcement strips and the photovoltaic module. This creates a multiple seal between the reinforcement strip and the photovoltaic module.

[0036] 4. The present invention utilizes the elastic portion of the upper hook member to compress the upper portion of the photovoltaic tile within it, while cooperating with the suspension member to position and suspend the lower portion of the photovoltaic tile. When the photovoltaic tile is suspended on the hook member, gravity exerts a downward force on the suspension member, further compressing the photovoltaic tile within the clamping space and improving the stability of the photovoltaic tile suspension.

DETAILED DESCRIPTION

[0053] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0054] Example 1

[0055] Please refer to Figures 1-10 As shown, a photovoltaic system that facilitates the disassembly and assembly of photovoltaic tiles comprises:

[0056] Photovoltaic module 1, which is used to convert light energy into electrical energy;

[0057] A keel assembly 2, used for fixing the photovoltaic assembly 1;

[0058] A plurality of hook members 3 are used to overlap the photovoltaic modules 1 on the keel modules 2 in a staggered manner by clamping and hanging, so as to realize portable assembly and disassembly of the photovoltaic modules 1. The plurality of hook members 3 are fixed on the keel modules 2 at intervals;

[0059] A water guide assembly 4 is used to drain water leaking between photovoltaic modules 1. Adjacent photovoltaic modules 1 on the same layer are overlapped on the water guide assembly 4.

[0060] The sealing member 5 is sandwiched between the hook member 3 and the photovoltaic module 1 .

[0061] This embodiment arranges a number of hook members 3 at intervals on the keel assembly 2, so that the photovoltaic assembly 1 is easy to disassemble and install under the clamping action of the upper hook member 3 and the hanging action of the lower hook member 3; at the same time, a water guide assembly 4 is provided between adjacent photovoltaic tiles 11, so that water that may seep into the seams between adjacent photovoltaic tiles 11 can be discharged from the water guide assembly 4, ensuring that the photovoltaic tiles 11 have a waterproof effect in the longitudinal direction; a sealing member 5 is provided between the hook member 3 and the photovoltaic assembly 1, and when the photovoltaic assembly 1 is pressed on the sealing member 5, a good sealing effect is formed between the two, thereby ensuring the lateral waterproof effect of the photovoltaic tiles 11.

[0062] It should be noted that, in this embodiment, the staggered overlap of photovoltaic modules 1 can be understood as the upper and lower overlap of adjacent photovoltaic modules 1, that is, the lower part of the upper photovoltaic module 1 overlaps the upper part of the lower photovoltaic module 1; staggered means that at least the joints of the adjacent photovoltaic modules 1 are staggered, such as Figure 2 shown.

[0063] like Figure 14 As shown, in this embodiment, the photovoltaic assembly 1 includes photovoltaic tiles 11, and a plurality of photovoltaic tiles 11 are connected to the inverter via connection terminals 12 and connecting wires 13 provided on the back.

[0064] It should be noted that the photovoltaic tile 11 is primarily comprised of, arranged in order from top to bottom, tempered photovoltaic glass, an upper layer of POE film, a monocrystalline silicon cell, a lower layer of POE film, an isolation insulating layer, and a metal base plate. Obviously, the photovoltaic tile 11 can also have some structural changes as needed. For example, to enhance the color of the photovoltaic tile 11, the tempered photovoltaic glass can be replaced with a colored glass panel; to blend in with the other nine non-power-generating tiles on the slate roof, the tempered photovoltaic glass can also be replaced with slate-like tempered photovoltaic glass. The connection relationship and operating principle of the various components of the photovoltaic module 1 are prior art and will not be elaborated upon in this application.

[0065] Please refer to Figure 3-Figure 6 As shown, the water guide assembly 4 in this embodiment includes a water guide plate 41. A partition plate 42 is vertically provided at the center of the water guide plate 41 along its length direction. A first support plate 43 and a second support plate 44 are provided on both sides of the partition plate 42 in parallel and at intervals. The first support plate 43 and the second support plate 44 are respectively used to support the two ends of adjacent photovoltaic modules 1 that are close to each other.

[0066] A first water guide channel 45 is formed between the first support plate 43 and the partition plate 42, and a second water guide channel 46 is formed between the second support plate 44 and the partition plate 42. A sealing structure 47 is provided between the first water guide channel 45 and the second water guide channel 46 along their length direction; when the photovoltaic module 1 is pressed onto the sealing structure 47, the sealing structure 47 divides the first water guide channel 45 and the second water guide channel 46 into independent and non-interconnected first water guide main channel 451 and first water guide secondary channel 452, as well as second water guide main channel 461 and second water guide secondary channel 462.

[0067] It should be noted that the above-mentioned water guide plate 41 is an aluminum alloy plate with both sides bent upward in the middle horizontally. Since the photovoltaic tiles 11 are respectively overlapped on both sides of the partition plate 42, that is, the upper part of the first water guide channel 45 and the second water guide channel 46. Generally speaking, rainwater may seep into the joints of adjacent photovoltaic tiles 11 and enter the first water guide main channel 451 and / or the second water guide main channel 461 located on both sides of the partition plate 42. Due to the presence of the sealing structure 47, independent spaces are formed between the first water guide main channel 451 and the second water guide secondary channel 462, as well as between the second water guide main channel 461 and the second water guide secondary channel 462. Therefore, rainwater can only be discharged along the inclined first water guide main channel 451 and / or the second water guide main channel 461, thereby ensuring the longitudinal waterproof effect of the photovoltaic tiles 11.

[0068] Considering the extreme case where the first water-guiding main channel 451 and / or the second water-guiding main channel 461 is blocked or the water volume is too large, and at the same time, the sealing structure 47 is partially damaged and leaking, some rainwater that flows through 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 through the inclined first water-guiding channel 452 and / or the second water-guiding channel 462. This makes the sealing structure 47 have a double water-blocking effect, thereby improving the waterproof effect of the photovoltaic tile 11 in the longitudinal direction.

[0069] Please refer to Figure 6 In order to improve the sealing performance of the sealing structure 47, the sealing structure 47 in this embodiment includes a D-shaped hollow sealing strip 471. The horizontal portion of the D-shaped hollow sealing strip 471 is fixed to the upper surface of the water guide plate 41. The outer periphery of the arc-shaped portion of the D-shaped hollow sealing strip 471 is provided along its length direction with a plurality of elastic reinforcement strips 472 for enhancing the sealing between the photovoltaic module 1.

[0070] Specifically, when the photovoltaic module 1 is pressed against the D-shaped hollow sealing strip 471, the entire sealing structure 47 is deformed by the pressure. Under the elastic force of the hollow sealing strip, the multiple reinforcement strips 472 are tightly pushed against the lower surface of the sealing strip, so that the multiple reinforcement strips 472 are in elastic contact with the photovoltaic module 1. The elastic contact here should be understood as contact with a certain pressure, thereby forming a multiple seal between the reinforcement strips 472 and the photovoltaic module 1. In this embodiment, the sealing structure 47 is made of rubber.

[0071] Please refer to Figure 4 and Figure 5 As shown, the height of the partition plate 42 is higher than the first support plate 43 and the second support plate 44 of the same height. When the photovoltaic component 1 is pressed on the sealing structure 47, its upper surface is flush with the upper surface of the partition plate 42.

[0072] It is understandable that in order to ensure good sealing between the partition plate 42 and the photovoltaic tiles 11 on both sides, waterproof sealing strips can be pasted on both sides of the partition plate 42. Under the squeezing of the photovoltaic tiles 11 on both sides, the waterproof sealing strip can have good waterproof performance between the partition plate 42 and the photovoltaic tiles 11, preventing rainwater from entering through the joints. Thereby further improving the longitudinal waterproof effect of the photovoltaic tiles 11. Taking into account that the waterproof sealing strip needs to be exposed to sunlight, the waterproof sealing strip can be made of silicone rubber in this embodiment. Silicone rubber has excellent high temperature resistance and weather resistance, and is suitable for sealing photovoltaic tiles 11 that are exposed to strong sunlight for a long time. It can effectively prevent moisture intrusion and maintain long-term stable performance.

[0073] Furthermore, in this embodiment, sealing strips for improving the sealing between the first support plate 43 and the second support plate 44 may also be provided on the upper portions thereof to improve the sealing between the first support plate 43 and the second support plate 44 and the photovoltaic module 1 .

[0074] Please refer to Figure 7 As shown, in order to improve the waterproof performance of the photovoltaic tile 11 in the horizontal direction, the sealing member 5 in this embodiment is a sealing rubber strip, which is arranged on the upper surface of the upper part of the photovoltaic tile 11.

[0075] Specifically, when adjacent layers of photovoltaic tiles 11 overlap, the upper layer of photovoltaic tiles 11 presses against the upper portion of the lower layer, applying pressure to the rubber sealing strip located above the lower layer. This elastically contacts the lower surface of the lower portion of the photovoltaic tiles 11, creating a strong seal between the rubber sealing strip and the upper layer of photovoltaic tiles 11. This effectively prevents rainwater from entering the lateral direction of the photovoltaic tiles 11, ensuring the lateral waterproofing of the photovoltaic tiles 11.

[0076] Please refer to Figure 8 、 Figure 9 and Figure 10As shown, in this embodiment, the hook member 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 is provided on the upper portion of the supporting portion 32 for facilitating fixation with the keel assembly 2. The hanging portion 31 is provided with a through hole 311 that is concentric with the mounting hole 321 and has a diameter larger than that of the mounting hole 321. The through hole 311 facilitates installation of an installation tool in a fastener that cooperates with the mounting hole 321.

[0077] The lower part of the support part 32 is located in the clamping space 33 and is provided with an elastic part 34 for providing elastic support to the photovoltaic component 1. The lower part of the hanging part 31 is provided with a bending part 35. The bending part 35 and the side of the hanging part 31 away from the support part 32 form a hanging space 36 for hanging the photovoltaic component 1.

[0078] 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. The function of the clamping space 33 is to compress the upper portion of the photovoltaic tile 11 located therein through the elastic portion 34 of the upper hook member 3, and to cooperate with the hanging portion 31 to limit and suspend the lower portion of the photovoltaic tile 11. It is understandable that when the photovoltaic tile 11 is hung on the hook member 3, due to the effect of gravity, it will exert a downward force on the hanging portion 31, thereby further compressing the photovoltaic tile 11 located in the clamping space 33, thereby improving the stability of the suspension of the photovoltaic tile 11.

[0079] Please refer to Figure 1 and Figure 2 As shown, the keel assembly 2 in this embodiment includes a plurality of transverse keels 21 arranged in parallel at intervals for fixing the hook member 3 , and a plurality of longitudinal keels 22 parallel to each other are fixed vertically at intervals on the lower part of the transverse keels 21 .

[0080] Specifically, the transverse keels 21 and longitudinal keels 22 are both constructed from square stainless steel tubes. To extend the service life of the transverse keels 21 and longitudinal keels 22, the stainless steel tubes can be galvanized or spray-coated to enhance their corrosion and weather resistance. Furthermore, a sunscreen coating can be applied to the stainless steel surface to effectively resist oxidation caused by ultraviolet rays and high temperatures, thereby extending the service life of the keel assembly 2.

[0081] Example 2

[0082] Please refer to Figure 11 As shown, a method for installing a photovoltaic system that facilitates the disassembly and assembly of photovoltaic tiles includes the following steps:

[0083] S1, determine the installation position of the angle bracket 6 according to the length of the transverse keel 21 and the longitudinal keel 22 to be fixed, and fix the angle bracket 6 to the structural layer 8 of the building through the expansion bolt 7.

[0084] It should be noted that the installation position of the angle brackets 6 is determined by the length of the transverse keels 21, and the longitudinal spacing between the upper and lower angle brackets 6 is determined by the length of the longitudinal keels 22. To enhance the overall strength of the keel assembly 2, each longitudinal keel 22 is fixed to the structural layer 8 via expansion bolts 7.

[0085] S2, fix the angle bracket 6 to the longitudinal keel 22 by welding or detachable fastening means, and level them; wherein the fastening means can be bolt fixing.

[0086] It is understood that the purpose of installing and leveling the longitudinal keel 22 is to improve its own flatness, thereby ensuring that the transverse keel 21 installed thereon also has good flatness, thereby improving the overall stability and support capacity of the keel assembly 2. This not only facilitates the installation of the photovoltaic module 1, but also ensures that the installed photovoltaic module 1 is highly flat and free of unevenness. The specific leveling method can be achieved by using a wire.

[0087] S3, according to the effective width of the photovoltaic tile 11, the hook members 3 are fixed on the transverse keel 21 at intervals to ensure that each photovoltaic tile 11 has at least two sets of hook members 3 in the upper and lower parts within its length range.

[0088] Specifically, in this embodiment, four hook members 3 are evenly spaced along the length direction of each photovoltaic tile 11 .

[0089] S4, install the water guide components 4 on the transverse keels 21 at intervals according to the effective length of the photovoltaic tiles 11;

[0090] S5, installing the photovoltaic tile 11: inserting the upper portion of the photovoltaic tile 11 fixed with the sealing rubber strip into the clamping space 33 of the hook member 3 and pushing the photovoltaic tile 11 to hang its lower portion into the bending portion 35.

[0091] It should be noted that the sealing rubber strip in this embodiment can be pre-glued to the upper portion of the photovoltaic tile 11 and then pushed together into the clamping space 33. To facilitate removal and installation of the photovoltaic tile 11, the distance between the top of the clamping space 33 of the upper hook member 3 and the bottom of the hanging space 36 of the lower hook member 3 should be no less than the sum of the width of the photovoltaic tile 11 and the depth of the bent portion 35.

[0092] S6 , repeat step S5 to install the photovoltaic tiles 11 , and overlap adjacent photovoltaic tiles 11 on both sides of the partition plate 42 of the water guide assembly 4 .

[0093] Please refer to Figure 12As shown, when the photovoltaic tile 11 is damaged or needs to be replaced for other reasons, the disassembly process is roughly as follows: push the photovoltaic tile 11 into the clamping space 33 of the upper hook member 3 until the lower part of the photovoltaic tile 11 is completely separated from the bending part 35, lift the lower part of the photovoltaic tile 11 upward to separate it from the hanging space 36, and pull the photovoltaic tile 11 toward the lower hook member 3 to easily remove the photovoltaic tile 11.

[0094] It should be noted that Figure 11 and Figure 12 The figures in the figure are the installation or disassembly sequence from top to bottom.

[0095] Example 3

[0096] Please refer to Figure 13 As shown, a photovoltaic building includes the photovoltaic system of Example 1. Specifically, the photovoltaic system is fixed to the roof of the photovoltaic building on the sunny side using the installation method of Example 2. Traditional non-power-generating tiles 9 are still used on the shady side of the photovoltaic building or in locations with low sunlight exposure. Of course, the photovoltaic system in this application can also be fixed directly or indirectly to the wall of the photovoltaic building through other structures.

[0097] It should be noted that when the width of the sunny roof is an integral multiple of the photovoltaic tiles, the roof is paved with photovoltaic tiles; that is, only the photovoltaic tiles 11 are hung on the keel assembly.

[0098] When the width of the sunny roof is not an integral multiple of the photovoltaic tiles 11 , the roof is made of photovoltaic tiles 11 in combination with non-power-generating metal tiles 10 that are easy to cut to adapt to the roof width.

[0099] Specifically, if Figure 13 Because the roof is shaped like a triangle, parallelogram, or trapezoid, when the roof width is not an integer multiple of the PV tiles 11, first, the shape of the keel assembly must be adjusted to the roof dimensions to accommodate the shape. Secondly, the corners of the roof must be filled by cutting non-power-generating metal tiles 10 on at least one side of the roof and then hanging them from the transverse keels 21 using hooks 3. At this point, the keel assembly 1 of the photovoltaic system is covered with PV tiles 11 and non-power-generating metal tiles 10.

[0100] At the same time, considering the heat dissipation of the photovoltaic system, a fascia board with ventilation effect is used at the eaves in this embodiment. Specifically, the fascia board can be a metal plate with a plurality of ventilation holes or fence-like gaps.

[0101] In addition, please refer to Figure 15As shown, the photovoltaic system in this application can be connected to an energy storage device via an inverter to store the electrical energy converted from sunlight for use at night. Of course, the inverter can also be connected to the power grid or user loads. Furthermore, it can be linked to a smart management platform through network control to achieve intelligent control and monitoring.

[0102] The present invention arranges a number of hooks 3 at intervals on the keel assembly 2. The upper hooks 3 clamp and the lower hooks 3 suspend, making it easy to independently disassemble and install the photovoltaic modules 1. Furthermore, a water guide assembly 4 is provided between adjacent photovoltaic tiles 11, allowing water that may seep into the seams between adjacent photovoltaic tiles 11 to drain through the water guide assembly 4, ensuring a waterproof effect in the longitudinal direction of the photovoltaic tiles 11. This also fully utilizes roof space, ensuring the building's aesthetics while also improving the utilization rate of solar energy and effectively conserving traditional energy.

[0103] The above is a specific implementation of the embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of this application.
