technical field

The invention relates to the field of photovoltaic module installation components, in particular to a slope roof waterproof photovoltaic module installation device.

Background technique

The use of buildings to build photovoltaic power generation systems is an important form of solar photoelectric conversion and utilization (building integrated photovoltaics), which can be divided into two categories: one is attached to the built roof (BAPV), and the other is Simultaneous design, simultaneous construction and installation (BIPV) with the building.

Attaching and installing photovoltaic power generation systems on buildings requires different installation methods due to different roof forms. Common installation methods include the method of connecting the main structure of the roof, the method of fixing with special fixtures, and the method of two-component adhesive bonding, etc. . It is necessary to drill holes in the completed roof during installation, which will damage the waterproof layer or roof material of the roof to a certain extent. In order to avoid water leakage during future use, the roof must be waterproofed. In addition, there is a small space on the back of the module for the attached installation, which is not conducive to the heat dissipation of the module, which will lead to a decrease in the output power of the system, aggravate the attenuation and aging of the module, and increase the risk of safe operation of the system.

To build a photovoltaic power generation system on an existing roof, in order to solve the problem of roof waterproofing, the installation method has the following technologies: Concrete flat roofs often use concrete briquettes to fix the photovoltaic system bracket; color steel tile roofs often use metal clamps to fix the bracket; Drill holes to fix brackets, etc., usually with waterproof bolt caps on the top of the bolts or use sealant at the drilled holes to improve waterproofness.

For example: In the Chinese invention patent application document with the application number 201110093218.2 and the name "A Waterproof Frame for Solar Cell Modules", a waterproof frame is disclosed. The waterproof frame is made of bending thin iron sheets. , The iron sheet may be blown away, the air flow on the back of the module is poor, which is not conducive to the heat dissipation of the module, and the waterproof effect and safety are poor, and the consumables are large and the structure is complicated, which is not easy to promote.

In addition, the patent number is 201220511424.0, and the Chinese utility model patent document named "Leakage-proof Frame Assembly for Photovoltaic Modules" discloses a leak-proof frame assembly. The frame assembly has good waterproof performance and can be installed on a sloped roof (BIPV). But its structure is complex, the increase of frame consumables is large, there are many parts, the installation process is complicated, the original production process needs to be changed during production, and the applicability and popularization are poor.

In addition, in the Chinese invention patent document No. 200910095312.4, titled "Automatic Drainage Fully Sealed Photovoltaic Building-Integrated Roof", a photovoltaic building-integrated roof is disclosed, which is suitable for dual-wave modules. Rainwater is collected and drained by adding "U"-shaped trough plates between adjacent components. The trough plates have poor flow of rainwater and a small amount of drainage. When the rainfall is large, there is still a problem of water leakage; and it takes up a lot of space. The installation area of the photovoltaic module is increased; there are many components, the installation process is complicated, and the manufacturing cost is high.

In addition, how to use the aluminum frame components of the current photovoltaic modules to design and construct BIPV power generation systems on south-facing roofs such as warehouses, factory buildings, facility agriculture, and livestock houses, and to solve the problem of water leakage on the photovoltaic array surface, the existing technology still needs to be improved.
