Operational energy self-sufficient cable-stayed bridge

Abstract

An operational energy self-sufficient cable-stayed bridge comprises a bridge main tower (11), a main beam (12) which is arranged at bilateral sides of the main tower (11), a bridge electricity device (10) and an electric generator device; the wind driven generator device which is integrally arranged inside the main tower (11) and the main beam (12) comprises a wind power generation module, a compressed air power generation module and an electricity detector (9); the output terminal of the wind power generation module is connected with the compressed air power generation module and the electricity detector (9); the compressed air power generation module stores energy of the wind power generation module; the output terminal of the compressed air power generation module is connected with the electricity detector (9); and the output terminal of the electricity detector (9) is connected with the electricity device. According to the operational energy self-sufficient cable-stayed bridge, the integral electric generator device is installed on the cable-stayed bridge, clean energy is utilized to achieve self-sufficient power supply of a bridge device, the existing bridge structure space of the cable-stayed bridge is effectively utilized to install the wind driven generator device, the construction cost of the bridge is saved, and the appearance of the bridge structure is attractive.

Description

technical field [0001] The invention belongs to the field of wind resource utilization, and relates to a bridge design for realizing self-sufficient power supply by using a wind power generating device. Background technique [0002] At present, the power supply sources of electrical equipment mainly include thermal power supply, solar power supply, and wind power supply. The above-mentioned power supply sources often have their own disadvantages in specific use. Taking the power supply of the bridge system as an example, the lighting system and other equipment on the bridge in the past. Electricity is provided by a thermal power generator factory, which is very expensive, and thermal power generation is likely to cause air pollution; if solar panels are used for power supply, due to the current technical level, the cost is also high, and it is not suitable for large-scale promotion and use; When wind energy is converted into battery energy storage, the battery needs to be re...

[0002] At present, the power supply sources of electrical equipment mainly include thermal power supply, solar power supply, and wind power supply. Electricity is provided by a thermal power generator factory, which is very expensive, and thermal power generation is likely to cause air pollution; if solar panels are used for power supply, due to the current technical level, the cost is also very high, and it is not suitable for large-scale promotion and use; If wind energy is converted into battery energy storage, the battery needs to be replaced frequently and can cause environmental pollution; therefore, it is necessary to provide a power generation device that can generate clean energy and has a reasonable cost
