Description

Technical Field

[0001] The utility model relates to the field of brackets, in particular to a photovoltaic bracket with an installation inclination angle on a color steel tile roof. Background Art

[0002] With the deterioration of the ecological environment and the reduction of fossil energy, photovoltaic power generation as a renewable green energy is increasingly widely used. At present, the application of solar photovoltaic panels on the roofs of industrial and commercial plants is very extensive. Most of the roofs of the plants are colored steel tiles, with large areas and large installed capacity. According to the orientation and geographical location of the roof, the appropriate photovoltaic panel inclination is designed to maximize the amount of solar energy received. Therefore, it is necessary to design a reasonable photovoltaic panel inclination according to the orientation and inclination of the colored steel tile roof and the local longitude and latitude to improve the power generation efficiency.

[0003] As the supporting component of photovoltaic panels, the angle of the photovoltaic bracket will directly determine the angle of sunlight irradiating the photovoltaic panels, affecting the working efficiency of the photovoltaic panels. If the supporting scheme and the inclination scheme are not properly selected, water accumulation, dust accumulation and high temperature may have a negative impact on the efficiency of photovoltaic panels. At the same time, color steel tiles may affect the power generation efficiency of photovoltaic modules under high temperatures in summer.

[0004] The prior art "A photovoltaic panel bracket for the shady side of a color steel tile roof" has a notice number of CN210201764U, which discloses a photovoltaic bracket for the shady side of a color steel tile roof, including a front crossbeam, a rear crossbeam, a front L-shaped support, a rear L-shaped support, a front clamp and a rear clamp, wherein the front crossbeam is connected to the horizontal portion of the front L-shaped support, the rear crossbeam is connected to the horizontal portion of the rear L-shaped support, the vertical portion of the front L-shaped support is connected to the front clamp, the vertical portion of the rear L-shaped support is connected to the rear clamp, the front clamp and the rear clamp respectively clamp the corrugations of the color steel tile roof, and the length of the vertical portion of the front L-shaped support is less than the length of the vertical portion of the rear L-shaped support. This technology can make the photovoltaic panel on the shady side form an angle of 6° with the color steel tile roof, so that the photovoltaic panel on the shady side has an inclination angle similar to that of the photovoltaic panel on the sunny side. However, the following problems still exist:

[0005] 1. The connecting bolts on the front (rear) clamps are used to clamp the convex ridges of the color steel tiles on the one hand, and on the other hand, they need to be connected to the L-shaped support. One connecting bolt needs to undertake the fastening work of two key components. Once loosened, it will have a significant impact on both key components.

[0006] 2. When fixing the front (rear) clamp on the color steel corrugated sheet, the L-shaped support must be fixed at the same time. When the angle needs to be fine-tuned during installation, the connecting bolts on the color steel corrugated sheet need to be loosened again. The operation is complicated and not easy to adjust. Utility Model Content

[0007] The utility model provides a photovoltaic bracket with an installation angle on a color steel tile roof, which solves the problem in the prior art that one connecting bolt is responsible for fastening two key components. At the same time, when the front (rear) clamp is fixed on the color steel corrugated tile, the L-shaped support member needs to be fixed at the same time. If the L-shaped support member needs to be fine-tuned when installing the photovoltaic component at a later time, the color steel corrugated tile needs to be loosened and then fine-tuned and fixed together, which is not easy to operate.

[0008] In order to solve the above technical problems, the utility model provides the following technical solutions: a photovoltaic bracket with an installation angle on a color steel tile roof, comprising a vertical head clamp, an aluminum angle and a guide rail, wherein one end of the aluminum angle is connected to the vertical head clamp and the other end is connected to the guide rail; the vertical head clamp has an upper section that is a vertical perforated plate and a lower section that is a clamping part, and the aluminum angle is connected to the vertical perforated plate of the upper section of the vertical head clamp. By providing a vertical middle opening structure on the vertical head clamp, the connection between the vertical head clamp and the aluminum angle and the connection between the vertical head clamp and the color steel corrugated plate are separated to form two separate connection parts, which can be installed or fine-tuned separately without affecting each other.

[0009] As a preferred solution of the photovoltaic bracket with installation angle on the color steel tile roof of the utility model, the vertical head clamp includes a fixed clamp and a movable clamp, the end of the movable clamp is embedded in the fixed clamp and can rotate along the embedding point, and the fixed clamp is connected to the angle aluminum.

[0030] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. Embodiment 1

[0031] Reference Figure 1-4 , this embodiment provides a photovoltaic bracket with an installation angle on a color steel tile roof.

[0032] The photovoltaic bracket with an installation inclination angle on the color steel tile roof includes: a vertical head clamp 1, an angle aluminum 2 and a guide rail 3, wherein the vertical head clamp 1 is used to fix the entire photovoltaic bracket on the color steel corrugated roof 4, the guide rail 3 is used to support and fix the photovoltaic component 5, and the angle aluminum 2 is used to connect the vertical head clamp 1 and the guide rail 3, and different photovoltaic component inclination angles can be achieved by setting angle aluminums of different sizes.

[0033] like Figure 2 As shown, the vertical head clamp 1 may include two clamping plates, and a vertical plate is arranged on one of the clamping plates; the vertical head clamp 1 may also include two clamping plates and one vertical plate, the two clamping plates form a clamping portion, and a vertical plate is connected between the two clamping plates. In this embodiment, the vertical head clamp 1 preferably includes two clamping plates.

[0034] Specifically, the vertical head clamp 1 includes a fixed clamp 11 and a movable clamp 12. The upper end of the movable clamp 12 is embedded in the fixed clamp 11, but the movable clamp 12 cannot be detached from the embedding point, and the movable clamp 12 can rotate along the embedding point to form different angles between the fixed clamp 11 and the movable clamp 12, so that it is convenient to operate when fixing the color steel corrugated board.

[0035] The shape of the lower half of the movable clamping plate 12 is made according to the shape of the color steel corrugated sheet to be installed, and two holes for bolts to pass through are opened on the plate structure of the movable clamping plate 12, which are used to clamp the color steel corrugated sheet by tightening the bolts.

[0036] The fixed splint 11 includes a first section 111 of the fixed splint and a second section 112 of the fixed splint, which are divided from the embedding point of the movable splint 12, wherein the shape of the first section 111 of the fixed splint is made according to the shape of the color-coated steel corrugated sheet to be installed, and the first section 111 of the fixed splint and the movable splint 12 cooperate to form a clamping portion, and holes for bolts to pass through are respectively opened at corresponding positions on the two clamping plates of the clamping portion, and the second section 112 of the fixed splint is a vertical plate-like structure, and an elliptical hole is opened on the plate surface. The purpose of setting the elliptical hole is that when on-site installation is carried out, if the size accuracy of the installation component is not high or the installation position accuracy is not high, the fastener can slide and adjust in the elliptical hole to eliminate installation errors.

[0037] like Figure 3 As shown, the angle aluminum 2 is composed of two plate-like structures perpendicular to each other. The angle aluminum 2 can be formed by welding two plates or integrally formed, and elliptical holes with staggered positions are respectively opened on the two plate-like structures. The vertical surface of the horizontally placed angle aluminum 2 (i.e., two plates of the angle aluminum, one is horizontal and the other is vertical) is connected to the second end 112 of the fixing clamp plate by bolts.

[0038] The guide rail 3 is an H-shaped guide rail 31, and a cavity with a groove is opened at the upper and lower ends of the H-shaped guide rail 31. The bolt cap of the fixing bolt is placed in the cavity. The upper end of the H-shaped guide rail 31 fixes the photovoltaic component 5 through the pressing block 6, and the lower end of the H-shaped guide rail 31 is connected to the horizontally placed angle aluminum 2.

[0039] Furthermore, the inner surface of the clamping part of the vertical head clamp 1 (the surface in contact with the color steel corrugated sheet) is a strong friction surface, and the vertical part of the vertical head clamp 1 (the surface in contact with the angle aluminum) is a strong friction surface, which can be formed by coating a layer of friction enhancer on the surface, grinding with sandpaper, sandblasting, adding rubber pads or adding suction cups, etc. In this way, the friction between the clamping part and the color steel corrugated sheet can be increased, so that the vertical head clamp 1 can be more firmly fixed on the color steel sheet.

[0040] In this embodiment, the vertical head clamp 1, the horizontally placed angle aluminum 2 and the H-shaped guide rail 31 are used in conjunction with each other. When in use, the lower part of the vertical head clamp 1 is first clamped with the color steel corrugated steel sheet by two bolts, and then the vertical surface of the horizontally placed angle aluminum 2 is connected to the second end 112 of the vertical head clamp 1 by bolts, the horizontal surface of the horizontally placed angle aluminum 2 is connected to the lower end surface of the H-shaped guide rail 31 by bolts, and the upper end surface of the H-shaped guide rail 31 is connected to the pressing block 6 by bolts, and the pressing block 6 presses the photovoltaic module 5 to fix the photovoltaic module 5. If it is necessary to adjust the inclination angle of the photovoltaic module 5, the size of the vertical surface of the horizontally placed angle aluminum 2 can be adjusted to achieve a photovoltaic module 5 that is too high or lowered at the end (thereby forming different angles, such as Figure 9-12 ).

[0041] In the present embodiment, the color steel corrugated sheet and the angle aluminum 2 are fixed by different fasteners. The two fixations are independent of each other, the structure is more stable, and when the two need to be adjusted, they can be adjusted separately without affecting each other. Embodiment 2

[0042] Reference Figure 5-8 As shown, this embodiment is based on the first embodiment, but is different from the first embodiment in that: this embodiment uses a vertical head clamp 1, a vertically placed angle aluminum 2 (that is, the two plates of the angle aluminum are vertical) and a Y-shaped guide rail 32 to cooperate with each other, and the purpose of the clamp, the angle aluminum and the guide rail is the same as that of the first embodiment, the difference is that the angle aluminum is fixed and placed in a different way, and the guide rail structure is different.

[0043] Specifically, the Y-shaped guide rail 32 includes a first section 321 and a second section 322. The first section 321 is slotted to form a hollow inner cavity. The transverse dimension of the slot is based on the passage of the fixing bolt, and the transverse dimension of the slot is smaller than the same-direction dimension of the inner cavity. The hollow inner cavity is used to place the fastening bolt caps of the connecting block 6. The second section 322 is a longitudinal strip plate structure, and a plurality of elliptical holes are opened in the plate structure along the longitudinal direction. The length of the Y-shaped guide rail 32 is set in combination with the photovoltaic panel laying area.

[0044] The second section 112 of the fixed clamp of the vertical head clamp 1 is connected to one of the plates of the vertically placed angle aluminum 2 by bolts. The bolts pass through the holes on the two plates and are then tightened by nuts. The other plate of the angle aluminum 2 is connected to the second section 322 of the Y-shaped guide rail 32, also using bolts.

[0045] When the inclination angle of the photovoltaic panel needs to be adjusted, the size of the angle aluminum 2 in the eave photovoltaic bracket A-1 and the ridge photovoltaic bracket A-2 can be adjusted to meet the needs of different inclination angles, such as Fig.13 The vertical length of the angle aluminum 2 is increased as shown.

[0046] like Fig. 9As shown in the simplified schematic diagram, when the inclination angle of the photovoltaic module needs to be the same as the inclination angle of the color steel tile roof, the angle aluminum 2 in the eaves photovoltaic bracket A-1 and the ridge photovoltaic bracket A-2 can use the same size, and the photovoltaic bracket can use a combination of a vertical head clamp 1, a horizontally placed angle aluminum 2 and an H-shaped guide rail 31 used in conjunction with each other, or a vertical head clamp 1, a vertically placed angle aluminum 2 and a Y-shaped guide rail 32 used in conjunction with each other.

[0047] like Fig.10 As shown in the simplified schematic diagram, when the inclination angle of the photovoltaic module needs to be larger than the inclination angle of the color steel tile roof, the photovoltaic panel bracket preferably uses: a vertical head clamp 1, a vertically placed angle aluminum 2 and a Y-shaped guide rail 32 that are used in combination with each other. The vertical dimension of the angle aluminum 2 in the eaves photovoltaic bracket A-1 is smaller than the vertical dimension of the angle aluminum 2 in the ridge photovoltaic bracket A-2. The specific dimension needs to be calculated based on factors such as the longitude and latitude of the local geographical location and the orientation of the roof. After calculating the required dimension, it is only necessary to adjust the vertical dimension of the angle aluminum 2. Other components are universal, which reduces the construction requirements for on-site construction masters and improves the construction progress.

[0048] like Fig.11 As shown in the simplified schematic diagram, when the inclination angle of the color steel tile roof is large, but the inclination angle required by the photovoltaic component is small, the photovoltaic panel bracket is preferably used: a vertical head clamp 1, a vertically placed angle aluminum 2 and a Y-shaped guide rail 32 are used in combination with each other, and the vertical dimension of the angle aluminum 2 in the eaves photovoltaic bracket A-1 is larger than the vertical dimension of the angle aluminum 2 in the ridge photovoltaic bracket A-2. The specific dimensions are determined as described above.

[0049] like Fig.12 As shown in the simplified schematic diagram, when the inclination angle of the color steel tile roof is different from the inclination direction required by the photovoltaic component, the photovoltaic panel bracket preferably adopts: the vertical head clamp 1, the vertically placed angle aluminum 2 and the Y-shaped guide rail 32 are used in combination with each other, and the size of the angle aluminum 2 in the eave photovoltaic bracket A-1 is adjusted to be larger than the vertical size of the angle aluminum 2 in the ridge photovoltaic bracket A-2.

[0050] When the cutting precision of the angle aluminum is not very high, the vertical height can be fine-tuned by forming an angle between the angle aluminum 2 and the vertical head fixture 1 to achieve fine-tuning of the tilt angle of the photovoltaic module. Fig.14 shown.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
