Description
Technical Field
The utility model relates to a wind generating set location fire control extinguishing device.
Background
Wind energy is used as clean energy and plays a very important role in global energy structure adjustment and transformation. China is rich in wind energy resources, the wind power industry develops at a high speed for many years, and the installed capacity leaps the first in the world. At present, the installed capacity of wind turbine generators in China is still in a continuous and rapid growth stage. However, as the capacity of a single machine of the wind turbine generator is larger and the operation time is longer, various accidents are more and more, wherein the fire accidents of the wind turbine generator occupy a large proportion and the loss is great. Wind farms are often built in remote areas and once a fire occurs, it is difficult for a fire engine to reach the site in a timely manner. In addition, the wind turbine generator is often installed at an altitude several tens of meters or even hundreds of meters away from the ground, so that fire is generated, and the effect of extinguishing fire on the ground is difficult to take. Therefore, the reliability of the fire-fighting system of the wind turbine generator is very important.
The research on the structure of the wind turbine generator mainly causes the factors of lubricating oil leakage friction heat generation such as a main shaft and a gear box, heat generation of a brake system, cable overcurrent, operation failure of electrical equipment, failure of power transformation equipment, lightning stroke, extreme weather conditions and the like. In addition, the conditions of wind turbine fire and the like caused by operation errors of unit maintainers accidentally exist. At present, fire extinguishers are also placed in the engine room of the wind turbine generator in China, but the safety of the wind turbine generator cannot be completely guaranteed. Firstly, the unit has no automatic fire-fighting equipment, can not find out early fire, can not extinguish fire early and can not control the fire. Secondly, rescue personnel cannot arrive at the scene in time after the fire disaster occurs, and even if the rescue fire extinguishing equipment arrives at the scene, the rescue fire extinguishing equipment cannot be used for the fire disaster. Therefore, the enhancement of the fire safety protection of the wind turbine generator is not slow at all.
A large amount of combustible and inflammable materials are used in the wind turbine generator, such as: sound insulation foam polluted by oil stain sediment is arranged in the cabin; the plastic cabin cover is made of glass reinforced thermosetting plastic, glass fiber reinforced plastic and glass fiber reinforced plastic; oil stains exist in the hydraulic system; gear box oils and other lubricating oils. These flammable materials not only are potential hazards of fire but also accelerate the spread of fire, leading to a rapid expansion of accidents. Hydraulic oil leakage of the hydraulic station and other reasons cause fire.
The electrical control system of the wind turbine generator is in an independent operation state. The wind turbine generator has long running time, electrical elements and cables are aged in different degrees, and the abrasion of mechanical parts is in an uncontrollable state outside a maintenance period. If the equipment is worn out of the normal working range, abnormal wear can be caused, and high temperature and friction sparks are generated. The poor ventilation of unit control cabinet leads to electrical components overheated and causes the conflagration. The contact resistance of the electrical loop of the unit is increased, and the internal short circuit and other reasons cause fire.
The main parts of the wind turbine generator are all at 60m high altitude, most of the geographical positions are located at the top of a mountain or a place with higher altitude, and the wind turbine generator is easy to be struck by lightning. The inside enclosure space that is of wind turbine generator system, if high temperature phenomenon appears, the heat is difficult for giving off. Especially when lightning strike happens, a large number of metal parts and grease are easy to burn in the sealed high-temperature unit to cause fire.
At present, many domestic wind power manufacturers clearly know that the fire risk is high, but the development policy of the domestic wind power industry is forced, and an effective fire fighting system cannot be adopted under the condition of low-price malignant competition of the market. Therefore, the fire-fighting equipment of the wind turbine generator is that a plurality of portable fire extinguishers are respectively arranged inside the tower base and the cabin. Due to the reason, the wind turbine generator generates fire under the unmanned condition, and the fire source and the fire development cannot be effectively restrained in the early stage of the fire, so that serious production accidents are finally caused.
