Flexible support distributed photovoltaic power generation system for sewage plant

Abstract

The invention discloses a flexible support distributed photovoltaic power generation system for a sewage plant, and the system is characterized in that a corrosion-resistant large-span flexible support is composed of corrosion-resistant rigid support assemblies at two sides and a corrosion-resistant flexible inhaul cable assembly which is transversely arranged at the top of the corrosion-resistant rigid support assemblies, and the corrosion-resistant flexible inhaul cable assembly forms a horizontal support network; the photovoltaic power generation assembly is fixed on a corrosion-resistant flexible inhaul cable assembly and is laid on a horizontal supporting network formed by the corrosion-resistant flexible inhaul cable assembly; a safety net is arranged below the photovoltaic power generation assembly; the cleaning equipment is laid on the corrosion-resistant flexible inhaul cable assembly and can clean the corrosion-resistant flexible inhaul cable assembly and the photovoltaic power generation assembly. Due to the fact that the corrosion-resistant large-span flexible support is adopted in the system, when the system is applied to the upper space of a sewage treatment plant, the corrosion-resistant effect is good, safety is high, and the support assembly and the photovoltaic power generation assembly can be conveniently cleaned in cooperation with cleaning equipment.

Description

technical field [0001] The invention relates to the field of distributed photovoltaic power generation and sewage treatment, in particular to a flexible support photovoltaic power generation system for sewage treatment plants. Background technique [0002] Distributed photovoltaic power generation refers to a distributed power generation system that uses photovoltaic modules to directly convert solar energy into electrical energy. Its principle is to install solar photovoltaic panels in places with good lighting conditions, and the direct current generated by the panels is converted into alternating current by a grid-connected inverter, and then supplied to the load inside the building. Distributed photovoltaic power generation is generally constructed near the user's site, and the operation mode is mainly based on the user's self-consumption and surplus power grid. [0003] Distributed photovoltaic power generation equipment includes photovoltaic cell components, photovolt...

AI Technical Summary

Problems solved by technology

[0008] (1) The laying and construction of the long-span tank of the sewage treatment plant is relatively difficult: the secondary sedimentation tank of the sewage treatment plant has a large diameter, few supports, and high technical difficulty; Many pipelines, high obstacles, difficult construction, etc.

[0009] (2) The investment is higher than that of the ground power station: because the sewage plant needs to be laid overhead in order to avoid the original facilities, the construction cost is higher than that of the ground power station

[0010] (3) Not conducive to operation and equipment maintenance: the photovoltaic equipment installed in the upper space is likely to cause interference to operation and equipment maintenance, resulting in inconvenience for sewage plant operators

[0011] (4) The flexible support is susceptible to water vapor corrosion in the sewage plant, accelerating its stress corrosion, etc.

[0012] (5) Because of the large span, the tensile force received is large. After a few years, it is easy to form increased stress, resulting in safety accidents such as pillar collapse and chain detachment.

[0013] (6) The position of the flexible support is high, it is difficult to clean, and the sediment is likely to cause a decrease in power generation. At present, automatic cleaning facilities are not suitable for photovoltaics in sewage plants. Regular manual cleaning is generally used, which requires a large amount of maintenance, high cost, and unsafe personnel.

[0014] (7) Safety risk: The photovoltaic panels assumed at high altitude are generally more than 2m long and 1m wide, and the objects are large. Once they fall, there is a risk of hurting people and damaging equipment
