Description

Profile installation accessories and photovoltaic module frame

technical field

The utility model mainly relates to installation accessories of photovoltaic components, in particular to a profile installation component and a frame of photovoltaic components.

Background technique

Profiles are objects with certain geometric shapes made of materials with certain strength and toughness through rolling, extrusion, casting and other processes. Due to the limitation of the manufacturing process, the cross-sectional shape of a profile is generally fixed, and its shape and thickness are uniform on each cross-section in the length direction. When selecting profiles, generally according to the actual installation requirements, select profiles that match in terms of shape, material, mechanical properties, etc. However, in the practical application scenarios of photovoltaic module frame profiles after installation, the applied loads at different positions of the profiles are not the same, which leads to deformation or even tearing easily at the local positions where the stress of the profile is high. In order to avoid such deformation Or tearing, in the prior art, the design of strengthening the overall profile is generally adopted, such as the overall thickening of the profile, which results in a waste of resources to a certain extent.

Profiles can be used to form various frames, assembled on the four sides of the outer side of the component, and play the role of supporting, fixing and protecting the corresponding workpiece.

As a specific application scenario, the solar photovoltaic module is to fix the laminate including the solar cell through the photovoltaic module frame. The function of the module frame is to enhance the mechanical strength of the module, seal the edges of the laminate and fix the laminate to the support, thereby forming a solar photovoltaic module, referred to as a photovoltaic module or module. Therefore, the strength of the module frame directly determines the overall strength of the photovoltaic module.

The main body of the existing photovoltaic module frame is generally made of aluminum alloy profiles, which are integrally formed by extrusion. Due to the aforementioned reasons, the same type of frame profile has a uniform cross-sectional shape and thickness, and the long and short sides of the component frame may be different, but the long side and the long side, and the short side and the short side are unified. In most cases, the long and short sides are also unified. This results in that when designing the strength of the frame of the component, it is necessary to design according to the place with the greatest stress, so that the frame as a whole meets the strength requirements of the place with the greatest force, resulting in redundancy in the strength of other parts of the frame, and ultimately resulting in a waste of cost.

Figure 1 shows a cross-sectional view of a profile, and Figures 2 and 3 show schematic diagrams of the profile used for assembling photovoltaic modules. As shown in the figure, the profile 11 has A side, B1 side, B2 side, C side and D side. A slot 12 for carrying the photovoltaic cells 20 is formed between the A surface and the D surface, and a cavity 13 is formed between the B1 surface, the B2 surface, and the C surface and the D surface; the C1 surface is located at the bottom of the cavity 13 in the C surface. The C1 faces inward and extends to form the C2 surface, and the C surface is the contact surface that contacts the photovoltaic support 30 when the photovoltaic module composed of the photovoltaic cell 20 and the module frame is installed. Generally speaking, there are bolt holes 14 on the C2 side, which can be used to fit the fasteners (not shown) to install the photovoltaic module on the bracket 30. In more cases, the pressing blocks 40 and B1 are used on the A side and the B1 side. Fasteners mount the photovoltaic modules on the bracket 30 . From the cost structure of the existing profiles, the B1, B2 and C2 surfaces constitute the main part of the raw material cost of the profiles.

FIG. 3 shows a schematic diagram of a purlin of a photovoltaic module mounted on a photovoltaic support. As shown in FIG. 3 , when the photovoltaic module is installed, the long-side profiles 11 of the module frame 10 are vertically installed with the purlins 31 of the bracket 30 . The width of the purlins 31 is generally 40-60 mm, and the positions of the two purlins 31 are generally in the region of 1/8 to 1/4 of the long side of the module. When the photovoltaic module is stressed, the stress of the module frame is the largest in this area (that is, the position where the module frame and the purlin contact and its vicinity), but the stress on the other parts of the module frame is relatively small. In the prior art, when designing the frame, the mechanical properties of the frame are designed with reference to the part with the largest stress, so that corresponding load redundancy is formed in the part with less stress.

In addition, in the bolt hole installation method in the prior art, the installation position is generally located on the inner extending surface (ie, the C2 surface) of the bottom of the frame. Due to the need to reduce the cost of photovoltaic modules in recent years, the wall thickness and width of the C2 surface have been reduced as much as possible, which leads to a reduction in the strength of the module mounting surface, and the bolt holes are often deformed or pulled through to fail. This technical problem can be solved by increasing the thickness of the bottom of the frame or widening the bottom of the frame. However, under the existing frame structure of the module, it is necessary to uniformly strengthen all the longitudinal directions of the long sides or at least widen the C2 surface, which will lead to a significant increase in cost and a large economic burden.

In addition, the inventors of the present application found that when a plurality of component frames are continuously installed on the bracket, many pressing blocks 40 and fasteners need to be used to install the component frames on the bracket 30, which leads to longer installation time.

After the photovoltaic module is installed on the frame of the photovoltaic module, it can be installed on the bracket as a whole, and fixed by the pressing piece and the bracket to form a photovoltaic system.

The photovoltaic module frame of the foregoing embodiments adopts the profile mounting accessories, which can enhance the mechanical performance of the module frame part, and this part constitutes the contact surface between the module frame and the installation station, and bears the greatest force. Therefore, when designing, it is only necessary to make the strength of this part of the component frame meet the maximum strength requirement, and the rest of the component frame can only meet the smaller strength requirements. In this way, the thickness of the main structure of the component frame can be reduced, and the cost of raw materials can be saved. On the other hand, the bottom of the profile can be opened, and at the same time, there is no mounting edge (C2 edge) on the profile, which further saves raw materials and reduces costs. In addition, since most areas on the profile do not have mounting edges, the shielding of the module frame on the back of the photovoltaic module can be reduced, the power on the back of the double-sided double-glass module can be effectively increased, and the double-sided ratio of the module can be increased, thereby improving the overall photovoltaic system. The power generation can reduce the cost of electricity; it can also make the light reception of each battery on the back more uniform, and the reliability performance is better. Profile mounting accessories form part of the profile height, which further saves the raw material of the profile.

In the photovoltaic module frame provided by the foregoing embodiments, since the length of the profile mounting accessories is smaller than that of the profile, and the height of the profile is smaller than the height of the profile, a hollow structure is formed at the bottom of the profile, and the bottom of the installed photovoltaic module has better air circulation and air circulation. Convective space. This can reduce the temperature of the photovoltaic modules in operation, and improve the working efficiency and service life of the photovoltaic modules.
