Distributed photovoltaic power station roof fire processing system

Abstract

The invention discloses a distributed photovoltaic power station roof fire processing system. The distributed photovoltaic power station roof fire processing system comprises an image type fire detector module, a fire alarm module, a fire blanket protection box module, a power trolley module and a system controller, wherein the image type fire detector module comprises an image type fire detectorfor monitoring the fire condition of a photovoltaic roof; the fire alarm module comprises an audible and visual alarm for giving an alarm when a fire occurs; the fire blanket protection box module comprises a fire blanket laid on the photovoltaic roof when the fire occurs; and the power trolley module comprises a power trolley for pulling the fire blanket to be laid. According to the distributed photovoltaic power station roof fire processing system, the fire extinguishing mode that the power trolley lays the fire blanket is adopted, a fire source is covered to block air, the fire condition can be accurately sensed, fire spreading is effectively prevented, and even fire is safely extinguished; and after the fire blanket is laid, sunlight is shielded, so that direct-current equipment is notelectrified, and the electric shock danger of operation and maintenance personnel is avoided.

[0002] Solar photovoltaic power generation has the advantages of rich resources, cleanness, and no restrictions on the geographical distribution of resources. In recent years, the photovoltaic industry has developed rapidly, and more and more photovoltaic power stations have been built. However, fire problems in photovoltaic power generation systems may cause huge losses to people and property.

[0003] In particular, the fire problem of the distributed roof photovoltaic power generation system combined with the building has the following characteristics compared with other fires: (1) The photovoltaic power station is still charged after being caught on fire, and because the electrical insulation is damaged or the live wire is broken and grounded, in the There will be step voltage and contact voltage within a certain range. If the operation and maintenance personnel do not pay attention when going to the roof to put out the fire, it may cause electric shock accidents; (2) The factory building covers a large area, and the general height is more than 7 meters. The space is large and the air circulation is good. Once a fire breaks out, the fire can spread in any direction, burn violently, and easily generate a strong hot air flow to form a large area of ​​combustion and cause a major accident; (3) The operation and maintenance personnel cannot find the fire on the roof in time, because the roof photovoltaic modules are installed in the open outdoor space The temperature and smoke sensors of the traditional fire monitoring system cannot timely and accurately sense the occurrence of a fire and give an alarm, and the operation and maintenance personnel cannot deal with the fire in time, causing the fire to expand; For unattended power stations, some roof power stations with relatively large capacity have a large number of roofs installed with photovoltaics, and the background monitoring room is also far away from some roofs, so it will take a while for the operation and maintenance personnel to arrive at the scene, thus delaying the fire timely extinguish
