Description

A torque tube with an octagonal cross section

Technical Field

The utility model relates to the technical field of photovoltaic brackets, in particular to a torque tube with an octagonal cross-section.

Background Art

Most of the existing torque tubes are used on photovoltaic brackets to connect photovoltaic panels and rotate the photovoltaic panels to achieve the purpose of adjusting the angle of the photovoltaic panels. The disadvantage of the existing torque tubes is that they cannot be further locked after the torque tubes are rotated and are prone to loosening. A lot of research has been done on this.

For example: the Chinese patent document "A heliostat support with corner braces" with application number CN201910405663.4 includes a column, on which a torque tube for performing sun-chasing action is provided; torque tube end plates are provided on both end faces of the torque tube, the upper end face of the torque tube end plate is provided with an upper chord of a support truss, and the lower end face of the torque tube end plate is provided with a lower chord of a support truss; a number of main purlins are provided on the two support trusses, the length of the main purlins is greater than the distance between the outer end faces of the support trusses, and the main purlins are used to place the mirror; corner braces are provided between a preset number of main purlins and the lower chord. The corner brace can increase the spatial stiffness of the support truss and the main purlin, thereby significantly improving the deformation of the structure under wind load, thereby reducing the wind vibration effect of the mirror and improving the focusing efficiency of the structure.

It can be seen that in the above-mentioned prior art, no locking device is provided in the torque tube, so that the torque tube cannot be locked after driving the photovoltaic panel to rotate to a certain angle, and the stability is poor.
