Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic, and particularly relates to a photovoltaic bracket for photovoltaic projects. Background Art

[0002] At present, large-scale ground photovoltaic power stations and rooftop photovoltaic power generation models are basically adopted both at home and abroad. There is almost no use of water surface resources for photovoltaic power generation. The only design is to build a floating platform with almost no gaps composed of several small floating bodies on the water surface, and the photovoltaic panels are directly laid on the floating platform or a metal bracket is built on the floating platform for installing the photovoltaic panels.

[0003] For example, the Chinese patent with the publication number CN210123952U discloses an aquatic photovoltaic bracket, including buoys and vertical support rods; three adjacent buoys are surrounded by a first framework to form an equilateral triangle shape. A bearing component is installed inside the first framework through a second framework. A guide sleeve installed at the center of the bearing component is inserted with a vertical support rod, and the threaded layer at the root of the vertical support rod is screwed with the inner threaded pipe wall inside the guide sleeve. This technical solution adopts a "complementary" splicing method to interlock every three adjacent buoys through the framework, and at the same time, a top plate for bearing is assembled at the center of the interlock of each group of buoys. The front and back "complementary" assembly method greatly reduces the installation space and simplifies the disassembly and assembly processes of the later staff. When the floating barrels are affected by wind and waves, they will float up and down. Through such a connection method, multiple groups of photovoltaic panels are rigidly connected together, and they will break later under the action of bending and swinging after long-term use. In view of this, we propose a photovoltaic bracket for photovoltaic projects. Summary of the Utility Model

[0031] In this embodiment, through such a setting, the cable 4 can be fixed through the anchor point, and further the device can move within a small range.

[0032] Based on the above structure,

[0033] In one embodiment,

[0034] The torsion spring sleeve 14 includes a housing 141. A central shaft 142 is rotatably connected to the middle of the housing 141. A winding wheel 143 is fixedly sleeved on the outer surface of the central shaft 142. The towing rope 13 is sleeved on the outer surface of the winding wheel 143.
