Description

Technical Field

[0001] The utility model relates to a photovoltaic system damper installation structure, belonging to the technical field of photovoltaic systems. Background Art

[0002] As an important component of the photovoltaic tracking system, the damper is mainly used to prevent the impact of excessive wind on the overall structure. When subjected to strong winds, the damper consumes wind energy to protect the overall tracking bracket.

[0003] As described in the Chinese utility model patent with application number 2021216794603, most of the existing dampers are set as a single and inclined installation on a single column. For this structure, there is only a short effective lever arm, and the rotational resistance torque is small. The damping effect of the damper cannot be fully exerted, resulting in the photovoltaic bracket having less than ideal stability when resisting strong winds. At the same time, the single damper structure cannot provide good support for the main beam, and long-term use may easily cause deformation of the main beam or failure of the damper.

[0004] In order to solve the above problems, this application proposes a photovoltaic system damper installation structure. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a photovoltaic system damper installation structure, which has the advantages of convenient installation, easy adjustment, and good wind resistance, and can effectively solve the problems in the background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A photovoltaic system damper mounting structure includes a column and a main beam, wherein a first damper and a second damper are symmetrically installed between the column and the main beam, an upper connecting seat for mounting the first damper and the second damper is fixedly installed on the main beam, and a lower connecting seat for mounting the first damper and the second damper is symmetrically fixedly connected at the lower position of the column, the upper connecting seat is fixedly connected by a transverse connecting piece and a lower clamp, and the transverse connecting piece is fixedly combined by a transverse U-shaped rod and an upper clamp. When the first damper and the second damper are installed, the upper clamp and the lower clamp are fixedly connected to the main beam, and the upper and lower ends of the first damper and the second damper are respectively connected to the transverse U-shaped rod and the lower connecting seat.

[0008] As a further improvement of the present invention, the lower connecting seat is configured to be integrally stamped or integrally cast, and the lower connecting seat is formed by a fixed combination of a column connecting plate and a triangular support member.

[0009] As a further improvement of the present invention, a conical support member is fixedly connected to one end of the triangular support member away from the column connecting plate.

[0010] As a further improvement of the present invention, the column connecting plate is fixedly connected to the column by bolts, and the column is provided with several groups of bolt holes in the vertical direction. The installation position of the first damper and the second damper is adjusted by installing the column connecting plate to the bolt holes at different positions on the column.

[0011] As a further improvement of the present invention, connecting ear plates are provided at both ends of the transverse U-shaped rod, and avoidance grooves are provided near the connecting ear plates.

[0012] As a further improvement of the present invention, the width of the upper clamp in the horizontal direction is greater than the width of the transverse U-shaped rod.

[0013] As a further improvement of the present invention, a horizontal plate is fixedly connected to both the upper and lower clamps, and a reinforcing rib plate is fixedly connected to the horizontal plate on the lower clamp and the outer side of the lower clamp.

[0014] The beneficial effects of the utility model are: a photovoltaic system damper installation structure, in which the damper is installed through an upper and lower adjustable structure, which is convenient for adjustment and installation. When the main beam tracks the sun and rotates, the damper on one side of the column is compressed while the damper on the other side is extended. When the entire photovoltaic tracking system is subjected to a large wind force and produces vibrations, the first damper and the second damper move in opposite directions at the same time, thereby better consuming wind energy and protecting the entire photovoltaic tracking bracket. Compared with the common inclined-installed single damper structure in the prior art, the force arms of the first damper and the second damper are longer, and the first damper and the second damper on both sides form a balanced structure, which is better able to resist strong winds. The dampers installed on both sides can better balance the wind force, and smaller dampers can be selected with almost no increase in cost. BRIEF DESCRIPTION OF THE DRAWINGS
