Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic technology, and particularly relates to a photovoltaic roof installation device.

Background Art

[0002] For the existing household photovoltaic roof, a photovoltaic support is installed on the roof, and then a photovoltaic module is installed on the photovoltaic support. For a pitched roof, there are existing solutions for laying photovoltaic modules on the south slope single slope, and there are also solutions for laying photovoltaic modules on both the north and south slopes at the same time. Of course, in order to support the photovoltaic module, a truss structure is also arranged on the roof at the same time, and the truss structure is fixed to the roof. However, the truss structure plus the weight of the photovoltaic module itself is relatively large. For some houses with a relatively long service life, the roof load-bearing capacity is poor, resulting in the inability to install a photovoltaic roof on the existing houses.

Content of the Utility Model

[0003] The utility model provides a truss-crossing-roof photovoltaic power station installation device, which solves the problem that a photovoltaic roof cannot be installed on some houses in the prior art.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: a truss-crossing-roof photovoltaic power station installation device, including a truss component spanning above the roof of a house, columns for supporting the truss component are arranged in front of and behind the house, the truss component is provided with a slope installation surface, and a photovoltaic module is installed on the slope installation surface.

[0005] Preferably, a diagonal brace is arranged between the upper part of the column and the truss component.

[0007] Preferably, the bottom of the column is connected with a ground pile.

[0009] Preferably, the top of the truss component is provided with an upper longitudinal rod, the lower end of the upper longitudinal rod is provided with a cantilever section, the lowermost cross beam is arranged on the cantilever section, and the bottom side of the lowermost photovoltaic module extends to the outside of the cantilever section.

[0010] Preferably, the bottom side frame of the photovoltaic module is provided with a dust and water guiding structure, and the dust and water guiding structure is used to make the dust follow the flowing water and drain away from the surface of the photovoltaic module.

[0011] Preferably, the dust and water guiding structure is a notch arranged on the transverse sides A on both sides of the bottom side frame of the photovoltaic module.

[0012] Preferably, a drainage structure is provided below the photovoltaic assembly, and the drainage structure comprises a transverse water guide groove provided below adjacent positions of two longitudinal rows of photovoltaic assemblies and receiving water flowing down from the bottom side frames of the photovoltaic assembly.

[0013] Preferably, the front side and the rear side of the truss assembly are both provided with oblique extension parts, and the inclination directions of the two oblique extension parts are opposite, and the top of the oblique extension part is provided with a sloped installation surface.

[0014] The utility model adopts the above technical solution and has the following beneficial effects:

[0015] 1. The truss assembly is supported by columns located on the front and rear sides of the house, so it can be installed above the roof, separated from the original house structure, without affecting the original house structure, solving the problem that some houses cannot be installed with photovoltaic roofs due to quality.

[0016] Since the truss assembly spans the house and the ridge, it can be used for houses with high ridges, rather than just ordinary double-slope sloping roofs without ridges.

[0017] Since truss assemblies are used to install photovoltaic modules, the advantage of the truss is that the rods mainly bear tension or pressure, which can give full play to the role of materials, save materials, and reduce the weight of the structure, thus forming a stable support for the photovoltaic modules.

[0018] In addition, when installing the truss assembly, you can first install the columns, then use the columns and lifting devices to lift the truss assembly, and finally install the photovoltaic assembly on the truss assembly, which facilitates the construction.

[0019] Therefore, the overall structure of the device is firm, the construction is convenient, and the performance of the house itself is not affected.

[0020] In addition, since the photovoltaic modules cover the roof and block direct sunlight from the roof, a photovoltaic insulation layer is formed, which not only effectively protects the roof, but also reduces the indoor temperature by 3℃-5℃, effectively alleviating the stuffiness of the house on hot summer days.

[0021] 2. Since an oblique brace is provided between the upper part of the column and the truss assembly, a stable triangular structure is formed between the column, the truss assembly and the oblique brace, and the support for the truss assembly is stable and reliable.

[0022] 3. Since the lower end of the lower longitudinal rod is welded to the oblique mounting plate or fixed with bolts, after the truss assembly is hoisted into place, it is convenient to quickly connect and reliably fix the truss assembly to the column.

[0023] 4. In order to ensure that the columns are fixed reliably, ground piles, such as spiral ground piles, are connected to the bottom of the columns so that the columns can stably support the truss assembly.

[0024] 5. The beam and truss assembly are connected together by welding or bolts, which facilitates the rapid connection and reliable fixation of the beam and truss assembly.

[0025] 6. Since a cantilever section is provided at the lower end of the upper longitudinal rod, the lowest crossbeam is arranged on the cantilever section, and the bottom side of the lowest photovoltaic module extends to the outside of the cantilever section, the area of ​​the photovoltaic module can be increased, the power generation efficiency can be improved, and a shielding structure can be formed in front of and behind the house to block rain and sunlight.

[0026] 7. The bottom side frame of the photovoltaic module is provided with a dust and water guiding structure, which is used to allow dust to be discharged from the surface of the photovoltaic module along with the running water, thus realizing the function of collecting dust at the bottom of the photovoltaic module and discharging it along with rainwater.

[0027] 8. The drainage structure includes a transverse water channel disposed below the adjacent positions of the two longitudinal rows of photovoltaic modules and receiving the water flowing down from the bottom side frames of the photovoltaic modules. Eventually, the dust is discharged along the drainage structure following the flowing water.

[0028] 9. Since the front and rear sides of the truss assembly above the roof are provided with sloped installation surfaces and photovoltaic modules are installed, the number of photovoltaic modules can be doubled compared to the single-slope photovoltaic modules. Under the same power generation efficiency, the power generation can also be doubled.

[0029] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[0040] Embodiment 1

[0041] Referring to Figures 1 to 3 As shown, a truss cross-roof photovoltaic power station installation device includes a truss assembly 3 that spans the house 6 and is located above the roof. Columns 4 for supporting the truss assembly are arranged side by side in front of and behind the house 6. The truss assembly 3 is provided with a slope installation surface, and a photovoltaic module 1 is installed on the slope installation surface.

[0042] In the technical solution of this embodiment, the truss assembly is supported by columns arranged on the front and rear sides of the house, so that it can be installed above the roof in an overhead manner, separated from the original house structure, without affecting the original house structure, and solves the problem that some houses cannot install photovoltaic roofs due to quality issues.

[0043] Since the truss assembly spans the house and the ridge, it can be applied to house types with high ridges, rather than just ordinary double-pitched roofs without ridges.

[0044] Since a truss component is used to install a photovoltaic module, the advantage of the truss is that the members mainly bear tension or compression, which can give full play to the role of materials, save materials, and reduce the structural weight. Therefore, a stable support can be formed for the photovoltaic module.

[0045] In addition, when installing the truss component, the column can be installed first, and then the truss component can be hoisted with the help of the column and the hoisting device. Finally, the photovoltaic module is installed on the truss component, which facilitates the construction.

[0046] Therefore, the overall structure of the device is firm, the construction is convenient, and it has no impact on the performance of the house itself.

[0047] In addition, since the photovoltaic module covers the roof and blocks the direct sunlight from hitting the roof, forming a photovoltaic heat insulation layer, it can not only effectively protect the roof surface, but also reduce the indoor temperature by 3°C - 5°C, effectively alleviating the stuffy situation of the house in hot summer days.

[0048] As Figure 2 shown, in order to ensure the stable support of the column for the truss component, a diagonal brace 5 is provided between the upper part of the column 4 and the truss component 3. In this way, a stable triangular structure is formed among the column, the truss component and the diagonal brace, and the support for the truss component is stable and reliable.

[0049] Furthermore, an inclined mounting plate 41 is provided at the upper end of the column 4, and a lower longitudinal bar 31 is provided at the bottom of the truss component 3. The lower end of the lower longitudinal bar is welded or fixed with bolts to the inclined mounting plate. When using a hoisting device to hoist the truss component, after hoisting the truss component in place, it is convenient for the truss component to be quickly connected and reliably fixed to the column.

[0050] To ensure the reliable fixation of the column, a ground pile 42, such as a screw ground pile, is connected to the bottom of the column 4, so that the column can stably support the truss component. Among them, the column can be made of square steel pipe, and the diagonal brace can also be made of square steel pipe, and the two are welded or fixed with bolts.

[0051] Specifically, the photovoltaic module 1 is fixed on the cross beam 2, and common pressing block components can be used, or other structures can also be used. The cross beam 2 and the truss component 3 are connected together by welding or bolts. It is convenient for the cross beam and the truss component to be quickly connected and reliably fixed.

[0052] As Figure 2 shown, an upper longitudinal bar 32 is provided at the top of the truss component 3, and a cantilever section 321 is provided at the lower end of the upper longitudinal bar. The lowermost cross beam is arranged on the cantilever section, and the bottom side of the lowermost photovoltaic module extends to the outside of the cantilever section. In this way, the area of the photovoltaic module can be increased, the power generation efficiency can be improved, and a shielding structure can be formed in front of and behind the house to block rainwater and sunlight.

[0053] Of course, other structures of the truss assembly are the same as those in the prior art and will not be described in detail here.

[0054] It is understandable that, whether it is a double-sided pitched roof structure or a flat roof, Figure 1 As shown, the front and rear sides of the truss assembly 3 can be provided with oblique extensions, and the two oblique extensions have opposite inclination directions. The top of the oblique extension is provided with an inclined mounting surface, and the photovoltaic assembly 1 is mounted. Compared with the photovoltaic assembly with a single slope, the photovoltaic assembly can be doubled, and the power generation can also be doubled under the same power generation efficiency.

[0055] Embodiment 2

[0056] like Figure 4 As shown, the photovoltaic module 1 is a rectangular structure with a frame 11 around it. In this embodiment, the bottom frame of the photovoltaic module 1 is provided with a dust and water guide structure 111. The dust and water guide structure 111 is used to allow dust to be discharged from the surface of the photovoltaic module along with the running water, thereby realizing the function of collecting dust at the bottom of the photovoltaic module and discharging it along with rainwater.

[0057] Specifically, the dust and water guiding structure 111 is a notch provided on the side A 110 on both sides of the bottom frame of the photovoltaic module. Usually, the dust on the surface of the photovoltaic module will be concentrated on the inner side of the bottom frame of the photovoltaic module, and the running water will flow down along the surface of the photovoltaic module and converge to the inner side of the bottom frame of the photovoltaic module. Since there are notches on the side A on both sides of the bottom frame of the photovoltaic module, the running water carries the dust away from the notch, thereby realizing the function of collecting dust at the bottom of the photovoltaic module and draining it with rainwater.

[0058] Referring to the prior art, a drainage structure is provided below the photovoltaic assembly, and the drainage structure includes a transverse water guide groove provided below the adjacent positions of the two longitudinal rows of photovoltaic assemblies and receiving the water flowing down from the bottom side frame of the photovoltaic assembly. A longitudinal water guide groove may also be provided below the adjacent positions of the two transverse rows of photovoltaic assemblies, the longitudinal water guide groove is connected to the transverse water guide groove, and receives the water falling from the transverse water guide groove. Finally, the dust follows the flowing water and is discharged along the drainage structure.

[0059] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
