Abstract
The utility model relates to a shortwave antenna rigid folded oscillator. The shortwave antenna rigid folded oscillator is composed of an installation steel pipe, feed point steel pipes, connecting pipes and dampers. The installation steel pipe and the feed point steel pipes are of the same diameter and are blind-hole pipes. A fixedly connected square groove is fabricated in the middle of the installation steel pipe. Two coaxial feed point steel pipes of the same length are fixedly disposed below the installation steel pipe through the connecting steel pipes. The installation steel pipe and the feed point steel pipes are connected through the connecting steel pipes to form a square framework. Dampers are fixedly disposed in two end sides of the installation steel pipe and two end sides of the two feed point steel pipes. The shortwave antenna rigid folded oscillator is a rigid folded oscillator which is composed of steel pipes and dampers, is fixed to a zero-point position of the folded oscillator by a supporting arm stretches horizontally on a platform. The dampers are packaged in two ends of the steel pipes. The shortwave antenna rigid folded oscillator is simple in supporting structure, firm and durable in structure and convenient to maintain, and can bear relatively high power.
Description
Technical field
The utility model belongs to field of antenna, relates to short-wave antenna oscillator, the rigid folded dipole of especially a kind of short-wave antenna.
Background technology
The cage circle that traditional short-wave antenna oscillator is made up of several copper cash or copper covered steel wire, belongs to flexible body, comprises cage modle oscillator or amounts to type oscillator.Although cage modle or amount to type oscillator processing technology comparative maturity and simple, ease of assembly and setting up, production cost will reduce relatively, and its hang is on supporting construction and to realize the feeding classification impact of multiple pass type antenna very large, and structure is more complicated, and easy care not.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of short-wave antenna rigid folded dipole, and this oscillator supporting construction is simple, and sound construction is durable, is convenient to safeguard, bears power larger.
The purpose of this utility model is achieved through the following technical solutions:
The rigid folded dipole of a kind of short-wave antenna, by being installed, steel pipe, feedback point steel pipe, joint steel pipe and damper form, installation steel pipe and a feedback point steel pipe are same footpath and are blind hole pipe, be shaped with an affixed square groove at the middle part that steel pipe is installed, the below that steel pipe is installed is fixedly mounted with two with long and coaxial feedback point steel pipe by joint steel pipe level, installation steel pipe and a feedback point steel pipe form a quadro frame formula structure by the connection of joint steel pipe, in the two side ends that steel pipe and two feedback steel pipes are installed, are all fixed with a damper.
And described two feedbacks point steel pipe is symmetrical, gap is therebetween feedback point.
And described damper is a stainless steel water tank, in it, be packaged with liquid, each damper all encapsulates damper by capping.
Advantage of the present utility model and good effect are:
1, this folded dipole is rigid folded dipole, is made up of steel pipe and damper, is fixed on the site at zero point of folded dipole by the flat support arm of stretching on platform, two ends encapsulation damper in steel pipe, supporting construction is simple, and sound construction is durable, be convenient to safeguard, bear power larger.
2, this folded dipole is the oscillator of multiple pass type high power short wave rotating antenna, and common antenna can be divided into different formulas, to realize the effect of several slave antennas.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model (broken section);
Fig. 2 is the A portion structure enlarged diagram of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, to the utility model, embodiment further illustrates; Following embodiment is illustrative, is not determinate, can not limit protection range of the present utility model with following embodiment.
The rigid folded dipole of a kind of short-wave antenna, by being installed, steel pipe 1, feedback point steel pipe 4, joint steel pipe 2 and damper 6 form, installation steel pipe and a feedback point steel pipe are same footpath and are blind hole pipe, be shaped with an affixed square groove 3 at the middle part that steel pipe is installed, this affixed square groove is the affixed point with support arm, is also the site at zero point of oscillator; The below that steel pipe is installed is fixedly mounted with two with long and coaxial feedback point steel pipe by joint steel pipe level, steel pipe is installed and is presented some steel pipe to form a quadro frame formula structure by the connection of joint steel pipe.
Two feedback point steel pipes are symmetrical, and gap is therebetween feedback point; In the two side ends that steel pipe and two feedback point steel pipes are installed, be all fixed with a damper, this damper is a stainless steel water tank, is packaged with liquid in it; Each damper all encapsulates damper by capping 5.
