Description
Technical field
The utility model relates to outdoor base tower thunder-lightning technical field, particularly relates to a kind of outdoor base tower lightning protection structure.
Background technology
Forest fire be a kind of sudden strong, there is wide, destructive large, the natural calamity of disposing difficulty of putting out a fire to save life and property, the feature that forest fire has sudden, randomness, can bring about great losses in the short time, accomplish early discovery, early control, early avoid being of paramount importance link in forest fire prevention and control, therefore how carrying out early warning in early stage, accurately and timely warning for forest fire is problem important and in the urgent need to address in forest fire prevention and control.
And the combustible of forest belongs to solid fuel.Its combustion process is generally divided into preheating, naked light burning and charcoal burning three phases; I.e. warm-up phase: when combustible is heated, temperature rises gradually, large quantity of moisture evaporation and dry, simultaneously occur local heating decomposition, generating portion combustible gas and non-flammable gases.But due to large quantity of moisture evaporation consumption of calorie, temperature rises slowly, and oxidation rate is very slow, only occurs smoldering, can't reach burning-point.Naked light combustion phases: after combustible is smoldered, temperature rises very fast, continue decomposes, volatilize the imflammable gas such as a large amount of carbon monoxide, hydrogen and hydrocarbon, become flammable mixed gas after mixed with air, oxidation, exothermic process are accelerated, are aggravated, after reaching burning-point, fuel gas is lighted immediately, produces carbon dioxide and steam, releases a large amount of light and heat energy.And make neighbouring combustibles temperature increase, cause burning to spread.The charcoal burning stage: when timber completes after naked light burning becomes charcoal, have the burning of flame just to stop, namely proceeding to the charcoal non-flaming combustion stage.Charcoal burning belongs to the red-hot burning of solid, because burning occurs in the surface of solids, therefore is also called surface combustion.Although it does not have flame, but still a small amount of light and heat can be produced.
And be generally adopt the mode that corresponding camera collection image information is set on Ji Ta in the monitoring of existing forest fire protection, therefore, forest fire protection control point is generally all located at mountain top, its Ji Ta requires that the height of camera is generally higher than the woods 10 ~ 20 meters, and shaft tower or Ji Ta adopt the steel tower of 15 meters or 18 meters to make, therefore its Ji Ta is very easily struck by lightning in the application, if and the lightning protection measures of Ji Ta is not in place, be easy to Yin Jita be struck by lightning after breaking out of fire phenomenon, Ji Ta is caused to become the explosive train of fire, this should not occur in whole Forest Fire Prevention System, also should avoid occurring, therefore, lightning-arrest and the ground connection of headend equipment shaft tower or Ji Ta directly affects the safety and reliability of whole system, lightning-arrest huge loss will be brought with ground connection once ignore.Therefore, improving the lightning ability of Ji Ta self further, is one of basic measures realizing forest fire supervision.
