Description
Technical field
This utility model relates to discharging rod technical field, especially relates to a kind of safeguard protection discharging rod that can eliminate Vortex Shedding.
Background technology
Single tube class communication tower discharging rod is made in top frequently with the common mode welded all, does not take strengthening measure, and when top diameter is bigger, discharging rod diameter can differ greatly with tower body diameter, thus the rigidity of structure can reduce suddenly much at discharging rod.Owing to ordinary lightning rod uses round steel pipe, its cross section is the least, so wind load is by the formation vortex that can be intertwined behind cross section, vortex can be formed under wind effect and come off, constantly Vortex Shedding can make discharging rod rolling move up, and rocks owing to little wind may result in discharging rod, so its slosh frequency can bear the round number of times of Fatigue Load far beyond steel in this single-pipe tower uses life cycle, extremely it is easily caused unexpected fracture to drop and hurt sb.'s feelings, there is potential safety hazard.
Summary of the invention
This utility model mainly solves discharging rod in prior art and, without strengthening measure, easily forms Vortex Shedding and discharging rod is rocked, cause the problem that discharging rod fracture is dropped, it is provided that a kind of safeguard protection discharging rod that can eliminate Vortex Shedding.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals: a kind of safeguard protection discharging rod that can eliminate Vortex Shedding, discharging rod is arranged on tower body top, the outer wall of discharging rod is provided with wrapping wire, discharging rod top it is fixed in the middle part of described wrapping wire, the two end portions of wrapping wire is spirally wound on the outer wall of discharging rod, it is fixed with ring flange in the inner chamber bottom of discharging rod, the first taper fastener it is provided with on ring flange, safety rope one end is fixed on taper fastener, safety rope passes downwards ring flange, described tower body inwall is fixed with installation flat board, it is provided with the second taper fastener on flat board installing, the safety rope other end is fixed on the second taper fastener through installation flat board from the bottom to top.This utility model is spiral winding wrapping wire on discharging rod outer wall, when wind blows on discharging rod along front, wind can be along the downward transmission of spiral wrapping wire, avoid the Vortex Shedding forming rule at discharging rod pipe rear portion, the oscillation crosswise that Vortex Shedding brings can be avoided further, thus significantly reduce discharging rod rock amplitude, improve the resisting fatigue degree of discharging rod, prevent discharging rod breaking releasing.Additionally this utility model increases safety rope bottom discharging rod, and discharging rod is connected by safety rope with tower body, has both met when discharging rod is installed and has been installed separately, and the fracture suddenly that can prevent from again discharging rod after permanent use causing due to fatigue rupture is dropped.Safety rope two ends are separately fixed on the first taper fastener and the second taper fastener, and the first taper fastener is stuck on ring flange, and the second taper fastener is stuck on installation flat board, and the first taper fastener and the second taper fastener are not fixing dead, more convenient installation and removal.
As a kind of preferred version, the two end portions of wrapping wire along contrary direction of rotation spiral cross winding on the outer wall of discharging rod.When wind blows on discharging rod along front, wind can be along the downward transmission of spiral wrapping wire, wrapping wire makes the wind of both sides form the wind direction that intersection is downward after by discharging rod, avoid the Vortex Shedding forming rule at discharging rod pipe rear portion, the oscillation crosswise that Vortex Shedding brings can be avoided further, thus significantly reduce discharging rod rock amplitude, improve the resisting fatigue degree of discharging rod, prevent discharging rod breaking releasing.
As a kind of preferred version, the two end portions of wrapping wire is wrapped on the outer wall of discharging rod along identical direction of rotation Double helix.This programme wrapping wire uses the double-spiral structure of identical direction of rotation, wind can be more smoothly to underdrive along spiral wrapping wire, avoid the Vortex Shedding forming rule at discharging rod pipe rear portion, the oscillation crosswise that Vortex Shedding brings can be avoided further, thus significantly reduce discharging rod rock amplitude, improve the resisting fatigue degree of discharging rod, prevent discharging rod breaking releasing.
As a kind of preferred version, being provided with perforation on the top of discharging rod, described wrapping wire is through perforation.Wrapping wire is through perforation, and wrapping wire two ends are wrapped on discharging rod outer wall with helical structure again, and this makes wrapping wire just can easily be fixed on discharging rod without welding.
As a kind of preferred version, being provided with the helicla flute of correspondence on discharging rod outer surface, described wrapping wire is close to helicla flute and is wound.It is more tight that this programme makes wrapping wire and air terminal surface be affixed, and reduces gap, and the wind so making front blow over does not passes through the space between wrapping wire and air terminal surface and forms Vortex Shedding at discharging rod rear portion.
As a kind of preferred version, being provided with a pair in discharging rod lower external face both sides and fix ear, the two ends of described wrapping wire are fixed on fixing ear after being wound to discharging rod bottom.Wrapping wire termination is bundled on fixing ear so that wrapping wire is without being subjected to, and installing/dismounting is convenient.
As a kind of preferred version, it is connected between tower body top with discharging rod lower surface and has some ribs, ribs is even spaced around discharging rod and arranges, ribs is long strip-board shape, ribs one end and air terminal surface are affixed fixing, the other end is affixed fixing with tower body top, is formed with space in place of discharging rod with tower body roof intersection.Discharging rod is installed and is played reinforcement fastening effect by this programme ribs so that discharging rod is less susceptible to crooked or falls down, and reserves space between ribs and tower body surface, discharging rod simultaneously so that wind energy more smoothly passes over ribs.
As a kind of preferred version, it is provided with cone tank on described ring flange surface, through hole it is provided with in cone tank, first taper fastener is arranged on cone tank, described safety rope safety rope passes downwardly through through hole and passes ring flange, is provided with cone tank installing, is provided with through hole in cone tank on planar surface, second taper fastener is arranged on cone tank, and the described safety rope other end is fixed on the second taper fastener through through hole from the bottom to top.
Therefore, the utility model has the advantages that: on discharging rod outer wall, spiral winding has wrapping wire, when wind blows on discharging rod along front, wind can be along the downward transmission of spiral wrapping wire, avoid the Vortex Shedding forming rule at discharging rod pipe rear portion, can avoid the oscillation crosswise that Vortex Shedding brings further, thus significantly reduce discharging rod rock amplitude, improve the resisting fatigue degree degree of discharging rod, prevent discharging rod breaking releasing.Attachment security rope between discharging rod and tower body, the fracture suddenly preventing from discharging rod after permanent use causing due to fatigue rupture is dropped and is injured people by a crashing object or smash article.
