Abstract
Description
Technical Field
[0001] The invention relates to the technical field of power transmission line fire extinguishing, and in particular to a high-pressure fine water mist turbofan device for power transmission line fire extinguishing. Background Art
[0002] Transmission lines are an important part of the power system. Once a fire occurs, it may cause power supply interruption, affecting the normal operation of society and residents' lives. Therefore, timely and effective fire-fighting measures are essential to ensure the continuity and stability of power supply. Transmission lines usually pass through natural environments such as forests and grasslands. Fires not only threaten power facilities, but also may destroy ecological balance and natural resources. Fires may cause power grid failures and affect the reliability and stability of the power grid. Through effective fire-fighting technology, the impact of fires on the power grid can be reduced to ensure the safe operation of the power grid. With the development of technology, the application of high-pressure fine water mist fire extinguishing systems has made transmission line fire extinguishing more efficient and environmentally friendly.
[0003] The high-pressure water mist fire extinguishing system uses a high-pressure pump to atomize water into fine droplets, achieving rapid fire extinguishing while reducing water damage. It has significant environmental and economic advantages. Since the fire extinguishing medium used is only water, it is harmless to the environment and human health, avoiding the emission of harmful chemicals and potential health risks. At the same time, it saves a lot of water resources in the fire extinguishing process, which meets the requirements of modern society for energy conservation and sustainable development.
[0004] Traditional fire response measures are often passive, that is, they are only initiated when a fire has occurred or is about to occur. This means that after a fire occurs, the time required to control and extinguish the fire may cause the fire to spread and cause more serious losses. At the same time, most turbofan devices are single fixed fire extinguishing devices and cannot be adjusted in time according to the fire situation. Summary of the invention
