Description

Technical Field

[0001] The invention relates to the technical field of water-based photovoltaic installation, and in particular to a novel water-based photovoltaic system. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. Photovoltaic power generation has a wide range of applications. It can generate electricity as long as there is light. It has good development prospects because of its high safety performance, green environmental protection, and no geographical restrictions. Photovoltaic power generation occupies a huge area due to its low capacity distribution density. Floating water photovoltaics are floating photovoltaic power stations built on the water surface of ponds, small lakes, reservoirs, and reservoirs to solve the problem of large land occupation of traditional photovoltaic power generation.

[0003] Floating photovoltaic power plants usually rely on floats to provide buoyancy, and the floats can be used as walkways for photovoltaic power plants to facilitate inspection and maintenance. The existing floating photovoltaic system mainly consists of a main float and an aisle float. The main float is used to install legs and photovoltaic modules, and the aisle float is spliced ​​around the main float to provide sufficient buoyancy, as well as space for workers to stand and walk during inspection and maintenance. In other words, when there are wind and waves, the force of the floating photovoltaic system is mainly concentrated on the connection between the floats. In order to ensure sufficient buoyancy, the floats are usually made of lightweight plastic materials, which are not as strong as metal materials that can withstand repeated impacts. Therefore, the existing floating photovoltaic system cannot meet the strength requirements of windy and wave-prone areas. The connection of the floats is often damaged, and the floats need to be frequently inspected and replaced, which has high maintenance costs. Summary of the invention

[0061] The first support inclined surface 321 is provided with a first slot 322 for the bolt or nut to fit in, and is used to limit the bolt or nut. When locking, just put the cap of the bolt (or nut) into the first slot 322, and then relatively twist the nut (or bolt).

[0062] The bottom end of the support bracket 32 ​​is provided with first horizontal extensions 323 on both sides thereof. The first horizontal extensions 323 are provided with first through holes 324 for passing bolts to lock the bottom end of the support bracket 32 ​​on the connecting beam 2 .

Then one or more splicing brackets 44 can realize the distance adjustment between the top bracket 42 and the bottom bracket 43, that is, the height of the rear support assembly 4 is adjusted, which is convenient for adapting to the photovoltaic components 1 with different tilt angle requirements; considering that the tilt angle requirements of the photovoltaic components 1 set in different longitudes and latitudes are different, the height of the rear support assembly 4 may need to be adjusted, and the manufacturer only needs to produce 3 parts (top bracket 42, bottom bracket 43, splicing bracket 44) to meet the use requirements of photovoltaic bracket support assemblies of different heights in different regions.

[0068] The above-mentioned rear support assembly 4 splits the existing integrated structure of the rod support into multiple parts in terms of structural design, and the various parts are locked by bolts.
