The shortwave station antenna is an over-water emergency aid station antenna satisfying the demands of intensity and rigidity, and having the advantages of appropriate weight, good dependability, and convenient and easy operation.

Description

The short-wave radio set antenna

Technical field

The utility model relates to a kind of short-wave radio set antenna, especially a kind of folding emergent short-wave radio set antenna waterborne.

Background technology

At present, the foldable antenna formed by high elastic modulus alloy steel pipe, titanium alloy plug, diverter, antenna body of known emergency set antenna waterborne.

In order to overcome existing short-wave radio set antenna, in the shortcoming of the result of use difference of low-frequency range, need increase the length of antenna in using at sea; Wind loading rating when at sea using for improving antenna needs overstriking mast diameter and strengthens its wall thickness; The material that mast adopted in the prior art has the shortcoming of Heavy Weight, and existing collapsible short-wave antenna relies on and is arranged on the elastica connection that respectively saves the mast inner chamber, rely on the elastic force length of run of elastica during use, this is concerning this particular surroundings of offshore applications, and reliability is relatively poor.

In sum, need select a kind of made mast for use with high strength, high rigidity, lightweight, highly reliable characteristics, make it satisfy the requirement that length is longer, diameter is bigger, the bar wall is thicker, weight is lighter, and need make its have folding, launch that motion action is simple, quick, high reliability features, be convenient to marine emergency communication and use.

The utility model content

The purpose of this utility model is to provide and satisfies intensity, rigidity and require, have lightweight, good reliability, emergency set antenna waterborne convenient to operation.

For achieving the above object, the technical scheme that the utility model adopted is:

A kind of short-wave radio set antenna, it comprise n joint mast, run through be arranged on connecting line in the more piece mast inner chamber, an end of connecting line is fixedly coupled the inner chamber end at described mast, at least one joint in the n joint mast has stage clip, stage clip inserts the inner chamber of mast, and one end thereof is fixedlyed connected with the internal chamber wall of mast, and its another end slidably is provided with and fixedlys connected with connecting line, connecting line is the polyamide fibre line, and the material of mast is an aluminium alloy.

Because the employing of technique scheme, the utility model compared with prior art has the following advantages:

Mast adopts aluminium alloy to make, and is satisfying that length is longer, diameter is bigger, in the thicker requirement of bar wall, is not increasing the weight of mast; Cooperate with stage clip to have replaced in the prior art with the polyamide fibre line to rely on elastica self elasticity to finish folding, the open and flat action of 18 joint masts, increased the reliability that antenna uses, also make the control procedure of antenna more quick simultaneously.

Embodiment

Short-wave radio set antenna as shown in Figure 1, it comprise n joint mast 1, run through be arranged on connecting line 2 in n joint mast 1 inner chamber, here, getting n is 18,18 joint masts 1 are divided into 4 antenna sets 4, promptly by the complete radio station antenna that is formed by connecting of the unit shown in the separator bar A-A left part among a plurality of Fig. 1.In this way, 4 groups of antenna sets are linked into an integrated entity, simultaneously, the set-up mode of grouping has been considered the effective interaction length of polyamide fibre line and spring reset power, has guaranteed the useful life of antenna and has launched effect.

In first antenna sets 4, the fixed block 6 that an end of connecting line 2 is fixedly connected by the leading section portion with this joint mast 1 is fixed on the inner chamber end of the first segment mast 1 of this antenna sets 4, be provided with stage clip 3 in the final section mast 1 of this antenna sets 4, one end thereof is fixedlyed connected with the internal chamber wall of mast 1, its another end slidably is provided with and fixedlys connected with connecting line 2, connecting line 2 is the polyamide fibre line, more excellent, be to adopt the less high strength polyamide fibre line of a kind of elastic deformation, the material of mast 1 adopts aluminium alloy.

Fig. 2 and Fig. 3 have provided the set-up mode of stage clip 3 in the final section mast 1 in each antenna sets 4, as shown in Figure 3, a slide block 5 is passed in the end that is arranged on the connecting line 2 in the mast 1, and fixedly connected with it, anti-limited slip block 5 comes off, the setting that offsets of an end of one end of slide block 5 and stage clip 3, under the traction of connecting line 2, slide block 5 is in mast 1 slides within; As shown in Figure 2, another end of stage clip 3 also offsets is provided with a fixed block 6, and fixed block 6 is fixedly connected by the inwall of connector 7 with this joint mast 1, and connecting line 2 passes fixed block 6.

Fig. 3 gives the connected mode between two adjacent antenna sets 4 simultaneously, the end of the final section mast 1 of previous antenna sets 4 is provided with a fixed block 6, fixedly connected with this fixed block 6 in an end that is arranged on the connecting line 2 in the line group one day after 4, in this way, former and later two antenna sets are coupled together.

When antenna is in non-working condition, adopt folding mode to place, 18 joint masts, 1 integrated pencil, at this moment, stage clip 3 is in compressive state, when needs use antenna, only a section of antenna need be dished out, rely on the reset force 18 joint masts 1 of stage clip 3 to launch automatically, join end to end.
