Description
Technical Field
The invention relates to the field of photovoltaic panel fire extinguishing equipment, in particular to an explosion-proof fire-fighting reconnaissance robot applicable to a photovoltaic power station.
Background
Photovoltaic panels, also known as solar panels, are the most important components in solar power generation systems. Photovoltaic panels are typically composed of a plurality of solar cells, other components of the solar panel including connectors, wires, panel holders, inverters, and the like. The inverter converts the direct current into alternating current so that the solar panel can provide electrical energy for home or business use.
When two contacts connected in the photovoltaic panel are electrified and separated, as long as the voltage in a circuit is more than 10-20V and the current is more than 80-100mA, an electric arc can possibly appear between a movable contact and a static contact, the phenomenon becomes direct current arc discharge, the damage of the direct current arc discharge is very large, the temperature of a conductor contact can be rapidly increased, and surrounding devices are carbonized at high temperature, a light person fuses a safety device and a cable, and a heavy person burns out components and equipment, so that fire is caused. In addition, after the photovoltaic panel is used for a long time, part of the battery pieces can be shielded by shadows and dust accumulation, and the local temperature of the photovoltaic module is increased due to different shielding degrees, pollution of bird droppings and the like, so that fire accidents are induced. In the event of a fire, the fire is likely to be very violent and difficult to control.

The robot integrates various technologies such as sensor technology, control technology, artificial intelligence and the like, and has the functions of autonomous navigation, fire source identification, fire extinguishment and the like. Fire-fighting robots in the prior art usually use water cannons to spray water mist or other fire extinguishing agents to extinguish fire, but fire of photovoltaic power stations is not generally recommended to directly use common water mist spray heads to extinguish fire, because photovoltaic materials are very sensitive to water, and once the photovoltaic materials are corroded by water, damage or short circuit of a battery plate can be caused, so that the power generation efficiency of the photovoltaic plate is affected and even the photovoltaic plate is disabled. In addition, water may also cause oxidation reactions on the panel surface, further damaging the panel. The fire blanket can be rapidly covered on the photovoltaic panel to isolate the contact between air and flame, so that the effect of rapidly extinguishing fire is achieved. In addition, after the fine water mist is sprayed into a fire scene, the fine water mist is quickly evaporated to form steam, and a barrier is formed around the combustion object together with high-pressure nitrogen to block the suction of fresh air, so that the flame is choked.
