Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and in particular to a photovoltaic support fixing device. Background Art

[0002] Renewable energy power generation is a national key development project. Carbon reduction in the construction field has become inevitable. We should vigorously develop photovoltaics. Ground photovoltaic parking sheds will be a new type of steel structure building product. It is one of the most effective ways to develop green buildings, effectively reduce building energy consumption, and implement carbon reduction actions.

[0003] One way to connect PV modules to purlins is to arrange PV modules vertically (the length direction of PV modules is perpendicular to the length direction of purlins, which is the front-to-back direction), arrange purlins at the openings on the bottom frame of the modules, and directly connect the module openings with the purlin openings using bolts. The punching method of purlin c can easily reduce the strength of purlin c. In addition, the vertical arrangement method results in the problem that two rows of parking shed modules cannot meet the front-to-back size requirements of parking spaces or the size of a single parking shed with three rows of modules is too large, which cannot plan parking spaces well and saves land, resulting in waste. This requires the carport PV modules to be arranged horizontally (the length direction of PV modules is parallel to the length direction of purlins, which is the left-right direction), see Figure 1 Purlin c is arranged under the long side of the frame of module a. However, in this arrangement, module a and purlin c are connected by pressing sheet b and bolts passing through purlin c and pressing sheet b. Due to the way purlin c is punched, the strength of purlin c is easily reduced. In addition, the width of the purlin flange is limited, and there is a risk of the photovoltaic panel slipping off.

[0004] There is an urgent need for a photovoltaic support fixing device that does not require purlin openings. Utility Model Content

In this way, under the condition of wind suction, the lower bending part of the pressure plate can firmly clamp the photovoltaic module, and form a double fixation of the photovoltaic module with the upper limit part of the support.

[0016] Thereby improving the limiting and fixing effect.

[0023] Further preferably, the support is a middle support for mounting and fixing the photovoltaic assembly located in the middle; the center of the upper limit portion is connected to the center of the lower limit portion through the connecting portion;
