Description

A waterproof photovoltaic carport

Technical Field

The utility model relates to the technical field of photovoltaic carport installation, in particular to a waterproof photovoltaic carport.

Background Art

Photovoltaic carports, as a new type of power generation, are the future development trend. It is mainly composed of a bracket system, a battery module array, a lighting and control inverter system, a charging device system, and a lightning protection and grounding system. The bracket system mainly includes supporting columns, inclined beams fixed between the supporting columns, purlins connected to the inclined beams for supporting the solar cell module array, and fasteners for fixing the battery module array. Under each carport, there is a junction box, where the solar panels on the top of the carport collect the absorbed electricity, and then transmit it to the inverter to convert direct current into alternating current, which can be transmitted to the power grid to complete the power generation. How to provide a new waterproof structure that meets the development trend of photovoltaic building integration while strengthening the waterproof performance should be the focus of technical personnel in this field.

There are two main types of waterproof structures currently, both of which have defects.

The first is waterproofing on the board, which is sealed with adhesive strips and glue or waterproof cover plates. Both adhesive strips and glue joint treatment require glue and adhesive strips, which have high construction requirements. If the contact is not properly handled, there is a risk of water leakage and the construction is troublesome and slow. The waterproof cover plate has high requirements for steel structure construction. There may be height differences between photovoltaic modules. The waterproof cover plate has poor contact with the module, which may cause water leakage.

The second is under-board waterproofing, where the photovoltaic modules are installed on the water channel through the cross arm. The installation of the water channel is troublesome and expensive. The water channel is directly fixed on the purlin with self-tapping screws. This method has strict construction requirements. Once fixed, it is difficult to adjust the position of the M water channel.

Moreover, both waterproof structures are not suitable for installation sites with relatively high wind speeds.
