Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module support frame technology, and more specifically, to a photovoltaic module support frame suitable for rooftops. Background Technology

[0002] With the increasing global demand for clean energy, solar photovoltaic power generation has been widely used as a sustainable energy utilization method. Among many photovoltaic power generation projects, rooftop photovoltaics has become an important way to popularize solar energy applications due to its advantages such as small footprint and convenient installation. Photovoltaic modules are used to directly convert solar energy into electrical energy to power electrical equipment or transmit electrical energy to the grid. Photovoltaic modules need to be supported by support frames during installation.

[0003] Different types of roofs, such as flat roofs, pitched roofs, and irregular roofs, have different structures and slopes. Most existing photovoltaic module support frames are designed in a single way and can only be applied to specific types of roofs, making it difficult to meet the diverse roof installation needs. For example, when traditional flat roof photovoltaic support frames are installed on pitched roofs, they cannot effectively adapt to the roof slope, which not only makes the installation difficult but also easily leads to unstable installation of photovoltaic modules, affecting power generation efficiency. Therefore, a photovoltaic module support frame suitable for roofs is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a photovoltaic module support frame suitable for rooftops to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic module support frame suitable for rooftops, comprising a support frame and a photovoltaic module disposed on the top of the support frame. The bottom of the support frame is fixedly connected to multiple fixing plates, wherein a threaded rod is disposed between two of the fixing plates, and a timing belt is sleeved on one end of the threaded rod. One end of one of the threaded rods passes through a fixing plate and is fixedly connected to a turntable. Rotating the turntable controls the rotation of the threaded rod through the timing belt, thereby achieving synchronous drive adjustment of the tilt of the support frame.

[0006] A stabilizing slider is sleeved in the middle of the threaded rod. A fixing block is fixedly connected to the bottom of the support frame away from the turntable. The bottom of both the stabilizing slider and the fixing block are rotatably connected to connecting screws. The connecting screw at the bottom of the stabilizing slider is rotatably connected to a telescopic rod. The connecting screw at the bottom of the fixing block is rotatably connected to a short rod. Mounting plates are provided on both sides of the bottom of the support frame. By rotating the threaded rod, the stabilizing slider can be moved to one end of the support frame, thereby adjusting the distance between the top ends of the short rod and the telescopic rod. The mounting plates can fix the bottom positions of the short rod and the telescopic rod, which is convenient for installation and use.

[0007] The mounting plate has symmetrically fixed connecting seats at both ends of its top. A fastening screw is inserted into the middle of the connecting seat. Limiting grooves and wear-resistant grooves are respectively opened at both ends of the connecting seat. A fastening nut is fitted on one end of the fastening screw, and a wear-resistant ring is fixedly connected to one side of the fastening nut. Anti-slip blocks are fixedly connected to the bottom ends of the short rod and the telescopic rod. Through the cooperation of the fastening screw and the anti-slip block, the connecting seat can be easily connected to the short rod and the telescopic rod. The bottom position of the short rod and the telescopic rod is fixed by the connecting seat. The screw head of the fastening screw is located inside the limiting groove, and the wear-resistant ring is tightly fitted with the inner cavity of the wear-resistant groove, so that the anti-slip block is squeezed by the connecting seat. This can fix the angle position of one end of the short rod and the telescopic rod, and improve the support stability of the support frame.

[0008] Preferably, the fixing block is disposed on one side of the threaded rod, and the fixing block corresponds to the threaded rod. Synchronous pulleys are symmetrically disposed at both ends of the synchronous belt, and the synchronous pulleys are fixedly sleeved on one end of the threaded rod, so that the short rod and the telescopic rod correspond one-to-one. At the same time, the rotation of the threaded rod controls the synchronous pulley to drive the synchronous belt to rotate, so that the two threaded rods can rotate simultaneously.

[0009] Preferably, the cross-sectional shape of the fixed block and the stabilizing slider is set to "U" shape. The multiple connecting screws, short rods and telescopic rods are all connected by threads. The telescopic rod is provided with a pin in the middle to fix the telescopic rod's extension length. The connection between the connecting screws, short rods and telescopic rods by threads facilitates connection and disassembly, and is convenient for combination and use. The length of the telescopic rod is fixed by the pin, which facilitates adjustment of the telescopic rod's length, thereby adapting to roof installation in different locations.

[0010] Preferably, the cross-sectional shape of the connecting seat is set to "U" shape, the connecting seat corresponds one-to-one with the anti-slip block, and the anti-slip block telescopic rod is set in the middle of the connecting seat. By cooperating with the anti-slip block, it is convenient to connect one end of the short rod and the telescopic rod to the connecting seat, and the angle of the short rod and the telescopic rod can be fixed by squeezing the anti-slip block through the connecting seat.

[0011] Preferably, the fastening screw passes through the middle of the anti-slip block, and the screw head at one end of the fastening screw is set inside the limiting groove and is adapted to the limiting groove. The anti-slip block is connected to the telescopic rod by the fastening screw, and the fastening screw is fixed by the limiting groove to prevent the fastening screw from rotating.

[0012] Preferably, the wear-resistant ring is disposed on the side of the connecting seat near the wear-resistant groove. The wear-resistant ring is adapted to the wear-resistant groove and is disposed inside the wear-resistant groove. By rotating the fastening nut, the connecting seat is squeezed and fixed by the connecting seat.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model first fixes the bottom positions of the telescopic rod and the short rod by the mounting plate. By adjusting the tilt angle of the short rod, the distance between the mounting plate at the bottom of the short rod and one end of the support frame can be adjusted. By adjusting the length and tilt angle of the telescopic rod, the distance between the mounting plate at the bottom of the telescopic rod and one end of the support frame can also be adjusted. This makes it convenient to install and use on roofs with different slopes. Furthermore, by rotating the turntable to adjust the position of the stabilizing slider, the position of the top of the telescopic rod at the bottom of the threaded rod can be adjusted, which facilitates the adjustment of the tilt angle of the support frame. This improves the practicality of the installation and makes it easy to adapt to various roof installations.

[0015] 2. This utility model also facilitates the connection between the anti-sliding block and the connecting seat by setting a fastening screw that passes through the second anti-sliding block of the connecting seat. The fastening screw is fixed by the cooperation between the screw head at one end of the fastening screw and the limiting groove.
