Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to an "X"-shaped steel pile foundation connection device. Background Art

[0002] At present, there are too many connection device accessories for fixing the longitudinal beam of photovoltaic panels on the existing "J" steel pile foundation. The position where the longitudinal beam connects to the "J" steel needs to install the base 1 first and then install the bottom plane 2 of the locking base, and finally lock the bottom plane on the "J" steel pile foundation. The whole installation process is too cumbersome, and the bolts and accessories used are also relatively large, which consumes a lot of installation labor time cost and material cost. Figure 1 As shown. In addition, the current method of fixing the connection device on the back of the "J" steel pile foundation requires the bolt to pass through the internal space of the "J" steel pile foundation to lock the connection device. The internal space of the "J" steel pile foundation is relatively small, and it is difficult for the installer's hands and installation tools to reach inside. In addition, the device for fixing the support pipe on the previous "J" steel pile foundation is not restricted in the left and right directions. Over time, it is easy to cause the photovoltaic bracket to rotate left and right, making the photovoltaic bracket unstable, such as Figure 2 shown. Utility Model Content
