Description
Technical field
The utility model relates to a kind of lightning proof, relates in particular to a kind of device of ancient and well-known trees lightning protection.
Background technology
Lightning Disaster is one of ten the Nature disasters of generally acknowledging in the world.May examine on the spot and sample analysis the disaster field of thunderbolt ancient and well-known trees by more than ten years, experimental study shows: thunderbolt is to cause ancient and well-known trees " bald ", " slightly withered ", " tree crown is withered ", and limb comes off, the immediate cause of the fission of tree body or damage.When the limb of its fracture is fallen, all can cause damage to pedestrian and heritage buildings.When the thunderbolt ancient and well-known trees, easily produce the secondary disasters such as side is launch aed surprise attack, earth potential counterattack public safety is caused serious threat.
The lightning protection of ancient and well-known trees is different from general changeless buildings or structures.Ancient and well-known trees are the plants with life attribute.Its body, branch bar all have variable at three dimensions in time.
Ancient and well-known trees grow in temple, scenic spot, house and field mostly, its lightning protection will consider that not only direct lightning strike is to the harm of ancient and well-known trees, should consider that simultaneously the secondary disasters such as in the lightning discharge process, the side that produces is launch aed surprise attack, earth potential counterattack are to the harm of pedestrian and public safety.
Its weak point of lightning protection device of using at present is: lightning rod adopts the all-metal body, without the independent support bar, Heavy Weight, its fixed form adopts circular wire metal wire, and contact area is little, disposable directly being fixed on the tree bar, not flexible surplus, degree of tightness is non-adjustable, and easily to the cortical layers of ancient and well-known trees and tough matter section injury, Inspection and maintenance is inconvenient.Next is drainage thread naked sheath, and due to the kelvin effect of electric current, lightning current easily produces creeping discharge, has reduced lightning protection function.Particularly in existing lightning protection device, do not consider the protection of the secondary disaster that produces in the lightning discharge process, the thunder and lightning pin all is not set in lightning protection device counts device, breaking of contact, warning mark and safety barrier, cause the lightning protection device afunction, stay thunder calamity hidden danger.
The utility model content
For the deficiencies in the prior art part, the utility model provides a kind of ancient and well-known trees lightning protection device.
These ancient and well-known trees lightning protection device is by lightning rod, support bar, anchor ear, drainage thread, breaking of contact, thunder-and-lightning counter, and warning mark, safety barrier and earth electrode consist of.
Lightning rod adopts the column type metal material, processes helical form cone along cylindroid through milling at needle point, and adds dish type most advanced and sophisticated, forms the multiple spot discharge tip.
The lightning rod support bar adopts the cast light weight insulating material to process, and has the characteristics anti-aging, anticorrosion, that wind loading rating is strong.
The lightning rod support bar uses the concertina type anchor ear, and its liner adopts sheet metal, and contact area is large, and overcoat adopts tool composite material springy to make.
Drainage thread adopts the multicore metal wire rod of tape insulation layer, have anti-aging, dielectric strength is high, the characteristics that conduct electricity very well.
This device adopts thunder-and-lightning counter, monitors, records the ruuning situation of lightning protection device, dynamically observes the lightning discharge situation.
Safety signs adopts triangle, black surround frame, the yellow end, is printed on thunder and lightning sign and Chinese and English caveat.
Safety barrier adopts timber or the stone material of non-metallic material.Being no less than the horizontal range of 3 meters apart from tree body edge, highly be not less than 0.8 meter, establish safety barrier.
This lightning protection device is connected with the lightning rod screw in the middle of drainage thread is passed support bar, lightning rod is connected with bracing stick joint, after lightning-arrest needle body and support bar connect, with the concertina type anchor ear, itself and ancient and well-known trees mobile jib are fixed, the drainage thread of support bar lower end is connected with screw with the breaking of contact upper end, the breaking of contact lower end is connected with screw with grounding lead streamline upper end, and grounding lead streamline lower end is connected band steel with earth electrode welds with thermofussion welding, earth electrode be connected the band steel electric welding and connect.From ancient and well-known trees peripheries 3 meters, the safety barrier of high 0.8 meter is being set, and at the other thunder-and-lightning counter of installing of drainage thread at 2.5 meters overhead, at 3 meters overhead, warning mark is being set simultaneously.
Advantage of the present utility model and effect:
Be that by the lightning rod of lightning protection device, the tip connects the sudden strain of a muscle thunder and lightning when the thunderbolt ancient and well-known trees; utilize drainage thread with lightning current, guide to earth electrode, thunder energy consumes and releases; the protection ancient and well-known trees through thunder-and-lightning counter, are recorded number of lightning strokes; and by warning mark and safety barrier; the caution pedestrian away from the deathtrap, plays and informs warning function; reduce the thunderbolt secondary disaster, the protection public safety.The thunderbolt ancient and well-known trees can effectively be defendd and reduce to this lightning protection device, growth, the survival of protection ancient and well-known trees.Effectively reduce simultaneously the thunderbolt secondary disaster to the harm of public safety.The fixed form of lightning rod adopts the concertina type anchor ear, is ductile.Lightning protection device has that volume is little, lightweight, easy installation and removal, passive work, reliability is high and the characteristics such as highly versatile.Be applicable to the lightning protection of individual plant, many strains ancient and well-known trees.This device is equally applicable to the lightning protection of tall and big trees.
