Embodiment
See accompanying drawing 1-7, rotor drum-type scarer of the present utility model, comprises cylinder 1, multiple rotor 2, spindle unit 3 and two supports 4 at the most;
Described cylinder 1, is combined into drum apparatus with described rotor 2, can rotate around described spindle unit 3, can cover the suspension insulator dish footpath of corresponding voltage grade circuit comprehensively.
Described rotor 2, the outer peripheral face being distributed in cylinder 1 symmetrically stretches out along cylinder 1 outer peripheral face; When rotor is subject to external force or wind-force operation, drives rotary drum, birds cannot be stopped, thus reach effect on driving birds.
Described spindle unit 3, described spindle unit 3 is arranged with described cylinder 1 is concentric, and can be flexibly connected around the mode of the axis rotation of described spindle unit 3 with cylinder 1 between spindle unit 3 with described cylinder 1;
Described support 4, is firmly connected with spindle unit 3, supports whole scarer, and is fixed on the tower material of cross arm of tower side.
During concrete enforcement, a major axis can be selected through the center of cylinder for spindle unit and described cylinder is stretched out at two ends; Two ends and the cantilever tip of spindle unit are fixedly connected.Coupling part smooth enough between spindle unit and described cylinder, frictional force is little, thus ensures the flexible rotating of drum apparatus.The two ends of spindle unit are fixedly connected with support and are supported by support, jointly play a supporting role.
Drum diameter and length directly determine to drive bird coverage, depend on electric transmission line isolator sheet diameter corresponding to 35kV-220kV grade, the diameter that group member has added up 220kV electric transmission line isolator sheet is about 255-280mm, by site inspection, drum length is 300mm, diameter is that 80mm coverage is better.
Rotor drum-type scarer of the present utility model, the External Force Acting be subject to or wind-force effect define its dynamical system of rotating.Under having wind state, once be subject to wind-force effect, scarer will rotate, and rotating speed varies in size along with wind-force and changes, and birds just cannot be close; Under windless condition, once be subject to External Force Acting (birds, branch etc.), rotary blade just drives a dress scarer to rotate instantaneously, the foreign matter such as birds or branch cannot be stopped stop, thus reach effect on driving birds, and can not birds be injured, serve anti-bird and the double action of protecting bird.
Described support 4 comprises the body of rod 5, and one end of the described body of rod 5 is provided with sleeve 6, and the other end of the described body of rod 5 is provided with as U-shaped connecting portion 7.
Described sleeve is for holding the end of described spindle unit, so that support cylinder and rotor.Described U-shaped connecting portion is provided with perforation 10, so that be fixed on the tower material of cross arm of tower side by support by bolt.During concrete enforcement, according to tower equipment structure on cross-arm, adopt that mechanical strength is high, band steel that compressive property is good development special stand, support adopts vertical structure, and solid and reliable, effectively can be connected with spindle unit, flexible rotation, it is convenient to install, and it is wide to drive bird area coverage.
Described spindle unit 3 comprises axis body 8 and bearing 9; Described bearing 9 is sheathed on described axis body 8, and the outer peripheral face of described bearing 9 matches with the inner peripheral surface of described cylinder 1, realizes relatively rotating between described axis body 8 and described cylinder 1 by described bearing 9; The two ends of axis body 8 are individually fixed in the top of two supports 4.During concrete enforcement, the two ends of axis body are inserted in the sleeve of described cantilever tip, and bearing has two at least.
Spindle unit comprises axis body and bearing, adopts sealing holoaxial type.Axis body adopts stainless steel material, and the diameter of axis body depends on the internal diameter size of bearing have certain nargin between the two, ensures flexibility rotatably.Adopt the mode of interference fit to coordinate between the periphery of bearing and the inner peripheral surface of described cylinder, make cylinder can around the axis rotation of described bearing.Bearing end 15mm is respectively stretched out on axis body both sides and support is connected and fixed.
The radial direction of described rotor 2 and described cylinder 1 or tangential between angle be 45 °.
During concrete enforcement, rotor is rectangle steel disc.Rotary blade number depends on cylindrical barrel symmetry, drives bird coverage, drum apparatus flexibility of revolution.Sheet number is few, and adjacent two panels space is comparatively large, once weeds or branch fall into, device easily blocks, and affects the effect on driving birds of package unit; Sheet number is more, drum apparatus heavier mass, and the frictional force that bearing bears can increase, and rotate effect is thereupon undesirable.By considering, rotary blade number is 6, is evenly distributed on cylinder, and angle 45 ° formed by rotor and cylinder tangent plane is best, and rotor width is the same with radius roller, to ensure to play rotor effect to greatest extent.
Rotor drum-type scarer of the present utility model is a kind of flexible rotation, broad covered area, installs, dismantles convenient, solid and reliable, meet anticorrosion and New-type bird repeller that is environmental requirement.Support is used for scarer to be fixed on above overhead line structures suspension insulator.Scarer above complete covering suspension insulator, can be able to rotate when there being wind, and birds time calm, once be parked on scarer and start to rotate, make birds stop, thus reach effect on driving birds.This device can effectively prevent birds to nest directly over suspension insulator and the phenomenon of frequent activities, stops the generation of the tripping fault caused because of bird pest.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
