Description

Technical fields:

[0001] This utility model relates to the field of photovoltaic support structure, and in particular to a novel openable bearing seat structure for use in photovoltaic tracking systems. Background technology:

[0002] As labor costs gradually rise, the market has placed higher demands on the ease of installation and disassembly. Currently, the industry mostly adopts integrated bearing housing solutions for the connection between the column and the spindle. The disadvantages are that the spindle is difficult to install and disassemble, and it is extremely inconvenient if the support collapses or maintenance is required.

[0003] In addition, photovoltaic tracking brackets are now widely used in desert areas, and the friction surface between the bearing housing and the bearing is the part most affected by sand and dust. If sand and dust continue to invade and cannot be effectively discharged, it will inevitably increase the wear of the bearing and reduce its service life. Most existing traditional bearing housing structures adopt an integrated round tube welding scheme, which is difficult to install and disassemble, and has no sand discharge function, making it easy for sand and gravel to invade, leading to accelerated bearing wear. Utility Model Content:

[0004] To address the aforementioned problems in the prior art, this utility model provides a novel openable bearing seat structure for photovoltaic tracking systems that is simple in structure, easy to install and disassemble, and capable of sand removal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel hinged bearing housing structure for use in photovoltaic tracking systems includes a hinged bearing housing and a double-flange bearing that cooperate with each other; wherein, the hinged bearing housing is installed on the top surface of the column assembly, the main shaft passes through the hinged bearing housing, and the double-flange bearings are installed on both sides of the hinged bearing housing.

[0007] Furthermore, the retractable bearing housing is a retractable cast bearing housing, including a cast base, a cast bearing cover, a pin, and fastening bolts that cooperate with each other; wherein, the cast base is fixed on the top surface of the column assembly, the cast bearing cover is snapped on top of the cast base, one end is hinged by the pin, and the other end is locked and fixed by the fastening bolts.

[0008] Furthermore, the hinged bearing housing is a hinged sheet metal bearing housing, including a sheet metal base, a sheet metal bearing cover, a second pin, and a third pin that cooperate with each other; wherein, the sheet metal base is fixed on the top surface of the column assembly, the sheet metal bearing cover is snapped on the top of the sheet metal base, one end is hinged by the second pin, and the other end is locked and fixed by the third pin.

[0009] Furthermore, chamfered sand discharge grooves are formed on both sides of the cast bearing cap.

[0010] Furthermore, sand discharge channels are respectively opened in the inner cavity of the sheet metal base and on the top surface of the sheet metal bearing cover.

[0011] Furthermore, the column assembly includes mutually cooperating columns and column connectors, with the column connectors fixed to the top surface of the columns and connected to the hinged bearing housing.

[0012] By adopting the above technical solution, the bearing housing of this utility model adopts an openable structure and is closed with a pin. During installation and disassembly, the main shaft can be installed and disassembled by removing the external pin, which significantly improves the installation efficiency compared with the one-piece bearing.

[0013] The bearing housing of this utility model has a guide groove formed on the side by reinforcing ribs or bending, so that sand and gravel can be left from the side. The bottom of the sheet metal design has a groove for sand discharge. Attached image description:

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0020] Figure 1-4 The image shown is an embodiment of this utility model.

[0021] A novel hinged bearing housing structure for photovoltaic tracking systems includes a hinged bearing housing 1 and a double-flange bearing 2 that cooperate with each other. The hinged bearing housing 1 is installed on the top surface of the column assembly 3, the main shaft 4 passes through the hinged bearing housing 1, and the double-flange bearing 2 is installed on both sides of the hinged bearing housing 1. The column assembly 3 includes a column 31 and a column connector 32 that cooperate with each other. The column connector 32 is fixed to the top surface of the column 1 and is connected and cooperated with the hinged bearing housing 1.

[0022] In a specific embodiment, the hinged bearing housing 1 can be a hinged cast bearing housing 11, including a cast base 111, a cast bearing cover 112, a pin 113, and a fastening bolt 114 that cooperate with each other; wherein, the cast base 111 is fixed on the top surface of the column connector 32, the cast bearing cover 112 is fastened to the cast base 111, one end is hinged by the pin 113, and the other end is locked and fixed by the fastening bolt 114; the cast bearing cover 112 forms chamfered sand discharge grooves 115 on both sides.
