Two sets of support structures are installed symmetrically along the slope of the sloping roof. The ends of the two sets of support structures are fixedly connected to form a top fulcrum. At least two sets of support structures are fixed to match the support structures. In the structure, there are several adjusting pin holes on both sides, the front end of the fixed frame is connected with the front end of the cross-shaped support frame, and the back end of the support frame. The support ring is supported on the connecting convex ring. Support structure design customization (slightly) To sum up, under the current social background, the application of solar energy resources has become more and more extensive, and the development and utilization of solar energy has gradually become a challenge. The installation of solar photovoltaic power generation bracket components and electrical appliances is a hot spot that the society attaches great importance to. The pile foundation is connected with the photovoltaic bracket. There are roughly two types of welding and bolting. With the vigorous development of photovoltaics, the land available for photovoltaic construction is becoming more and more scarce, and photovoltaic power stations are gradually developing towards tidal flats, river banks, water surfaces, and mountains. Among the internal ground photovoltaic projects, the proportion of photovoltaic power stations built on river banks is increasing year by year. How to reduce the cost of the photovoltaic module bracket of the photovoltaic power station on the ground riverbank has become an urgent problem to be solved. 2 Investigation of the status quo The upper structure of the photovoltaic support must meet the requirements of strength, coordination and rigidity. In the installation of solar photovoltaic power generation bracket components, the upper structure of the photovoltaic bracket directly affects the pressure state of each member in the bracket structure, and ultimately determines the cross-sectional model of each member, and the weight of each member determines the weight of the upper structure of the photovoltaic bracket.
The two ends of the photovoltaic bracket are respectively fixedly connected with the front and rear positioning clamps. The angle between the inclined rod and the horizontal plane is equal to the inclination angle of the photovoltaic support. The front positioning clamp is composed of a vertical plate, a horizontal plate, a positioning plate, a positioning column, and a vertical plate. , And can hold the sand and dust on the solar panel with good fixing performance, which is specially used in desert windy areas. The purpose of the utility model is to provide a solar photovoltaic support vertical plate whose length direction is parallel to the front pillar of the photovoltaic support. The worm gear is mounted on a rotating shaft, the rotating shaft passes through the housing, the top and bottom of the rotating shaft are connected with a rotating plate, and the rotating plate is connected with a photovoltaic mounting plate. The utility model aims at the problem of not needing to adjust the height and angle in real time in the existing photovoltaic panel support. Solar photovoltaic power generation bracket assembly electrical installation, proposed an improvement plan, the use of cylinder, motor, worm gear, worm drive system to drive the photovoltaic panel to keep rotating, so that the photovoltaic panel's sunshine, increase the working power of the photovoltaic panel. The photovoltaic panel mounting frame includes photovoltaic panels, short poles, long poles, and a triangular support frame connecting the short poles and the long poles. The upper end of the short pole is hinged with a U-shaped clamp block, and the top of the long pole is fixed with an L-shaped clamp. A photovoltaic panel is sandwiched between the U-shaped clamping block and the L-shaped clamping block, and a buffer pad is installed between the bottom surface of the photovoltaic panel and the triangular support frame. Solar photovoltaic power generation bracket components are installed in electrical appliances, and the cushions are respectively sponge layer, partition plate, spring and fixed plate from top to bottom. The setting of the U-shaped clamping block and the L-shaped clamping block can quickly and firmly clamp and install the photovoltaic panel.
Photovoltaic bracket is installed at the end of the adjusting frame and the adjusting groove on the fixing frame is fixed by bolts, the end of the fixing frame is provided with a stabilizer, and the upper surface of the four ends of the cross-shaped support frame is provided with four limits. The positioning device, the fixed frame and the supporting frame, and the horizontal plates are all rectangular plates, the supporting frame and the adjusting frame are connected by a rotating mechanism, and the bracket unit includes the utility model for easy installation. Improve bearing capacity. The spiral steel pile foundation can have a larger cross-sectional size, which greatly increases the basic lateral resistance and end resistance of the pile, and effectively improves the foundation's bearing capacity and anti-settlement ability. Multiple anti-corrosion measures. Increase the concrete strength level (above C40), increase the thickness of the protective layer (not less than 40mm), and add a composite anti-corrosion and rust inhibitor (required to have anti-corrosion effects on corrosive media such as chloride ions and sulfate ions). The electrical installation of solar photovoltaic power generation bracket components, the surface of the piles are coated with epoxy asphalt (or polyurethane asphalt) coating (thickness is more than 500m) and other multiple anti-corrosion measures to improve the structure's anti-corrosion performance and durability. Piling method. There are three common pile driving methods: static pressure pile driving, vibration pile driving, and hammer driving pile driving. The prefabricated pile and the photovoltaic support need to be embedded with steel plates (or embedded bolts) on the top of the pile. The method of hammering the pile is easy to damage the embedded steel plates (or embedded bolts) on the top of the pile, and it is difficult to guarantee the construction accuracy, so it is not recommended to choose .
The upper surface of the fixing frame is equipped with an adjusting groove. The photovoltaic frame includes a fixing frame, which is characterized in that the civilian flat-top-mounted adjustable photovoltaic frame has a huge advantage of being adjustable compared with the traditional parallel fixing frame, and The traditional weight-increasing device is removed, the load is reduced, the cost is reduced, and it is more suitable for civil installation. It is characterized in that it includes a plurality of uprights and at least two sets of support units. The month-on-month reduction in the installation cost of photovoltaic panels has effectively improved the omnidirectional rigidity of the bracket, and the appearance is neat and beautiful. Give full play to the exposure of double-sided photovoltaic modules. The photovoltaic module installation frame includes an aluminum alloy base plate and an aluminum alloy main frame, the aluminum alloy main frame body is in a horizontal U shape, and a clamping groove is formed between the lower frame of the aluminum alloy main frame and the two side frames, An adapter piece is arranged vertically below the lower frame of the aluminum alloy main frame, and the adapter piece includes an adapter shaft and a second adapter shaft.
