Specific implementation mode
In the following, in conjunction with Fig. 1 to Fig. 6, the invention will be further described.
A kind of log-periodic antenna of Automatic-expanding collection, including the mast 7 of telescopic lifting and shake
Sub- cable 2 is respectively fixed with upper rack posts 1 and lower fulcrum bar 3 in first segment, the third section of mast 7,
On the second section of mast 7 it is fixed there are two the antenna oscillator set line bar I5 of horizontal parallel setting and
Antenna oscillator set line bar II6；Multiple oscillator cables 2 are correspondingly arranged at upper rack posts 1 respectively and antenna shakes
Between subclass line bar I5 and between lower fulcrum bar 3 and antenna oscillator set line bar II6；Oscillator cable 2
Folding and unfolding end by oscillator distributor 4 respectively correspondence be fixed on upper rack posts 1 and lower fulcrum bar 3, it is another
End is separately fixed on antenna oscillator set line bar I5 and antenna oscillator set line bar II6.Described shakes
Sub- distributor 4 is made of shaft 8, wind spring 9, reel 10, and shaft 8 is fixed in 9 one end of wind spring,
The other end is fixed on reel 10；Shaft 8 is fixed on upper rack posts 1 and lower fulcrum bar 3.Described shakes
Sub- cable is formed by 3 layers, and central core is load nonmetallic core 11, and outermost layer is insulating sheath 13,
In middle layer close to 3 one end of upper rack posts 1 or lower fulcrum bar be that non-metallic weaves 14, shake close to antenna
The middle layer of subclass line bar I5 and the one end antenna oscillator set line bar II6 is to weave 12 by metal tape.
Working principle of the invention is as follows：
Power antenna bar 7 is raised section by section.
When 7 first segment of power antenna bar starts to increase (other sections are motionless), uppermost upper branch is driven
Bar 1 increases, while oscillator distributor 4 being driven to increase together, is wrapped on oscillator distributor 4 at this time
Oscillator cable 2, and 2 other end of oscillator cable is fixed on antenna oscillator set line bar I5 and antenna oscillator
Gathering line bar II6, (antenna oscillator set line bar I5 and antenna oscillator set line bar II6 are fixed on electronic day
It is line bar 7, motionless at this time), thus 4 under tension of oscillator distributor and unwrapping wire.When power antenna bar 7
When one section is increased in place, 4 unwrapping wire of oscillator distributor in place, a half above log-periodic antenna at this time
Amount oscillator expands in place.
When power antenna bar 7 second, which saves, to be started to increase (below other sections it is motionless, logarithm period at this time
Antenna the upper surface of has been unfolded general oscillator and has increased), drive antenna oscillator set line bar I5 and antenna
Oscillator set line bar II6 starts to increase, while driving and being fixed on antenna oscillator set line bar I5 and antenna
The oscillator cable 2 of oscillator set line bar II6 increases together.At this time oscillator is wrapped on oscillator distributor 4
Cable 2, and 2 other end of oscillator cable is fixed on (the nethermost lower fulcrum bar 3 of nethermost lower fulcrum bar 3
It is be fixed on the third section of power antenna bar 7, motionless at this time), thus 4 under tension of oscillator distributor and
Unwrapping wire.When power antenna bar 7 second section increase in place when, 4 unwrapping wire of oscillator distributor in place, at this time
Half quantity oscillator expands in place below log-periodic antenna.So entire log-periodic antenna is opened up completely
It opens.When the third section of power antenna bar 7 starts to increase, entire log-periodic antenna starts whole liter
Height, when the whole of power antenna bar 7 increases in place, log-periodic antenna increases in place.
The collection sequence of log-periodic antenna is opposite with expansion sequence.When power antenna bar 7 third section with
Under (including third section) collection in place when, the nethermost lower fulcrum bar 3 of log-periodic antenna reduces in place
(motionless).When the second section of power antenna bar 7 starts to reduce, the oscillator for being fixed on lower fulcrum bar 3 is received
It puts device 4 to start to wind half quantity oscillator cable 2 below log-periodic antenna, when the second pole is reduced to
Half quantity oscillator is collected in place below log-periodic antenna when position.Identical principle, works as power antenna
When the first segment of bar 7 is reduced in place, half quantity oscillator is collected in place above log-periodic antenna, this
When entire log-periodic antenna collection in place.
