Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of installation/composite type feed easy to maintenance.
The purpose of utility model can realize through following technical proposal: a kind of composite type feed; Comprise parabolic antenna, pass parabolic antenna and tuner and subreflector fixed thereon; It is characterized in that, between subreflector and tuner, be removably connected with the guide frame that supplies signal to transmit.
Penetrate the signal that comes from satellite and be mapped on the parabolic antenna, signal is mapped on the subreflector through the parabolic antenna reflection, and signal is mapped in the tuner through guide frame again, and tuner becomes intermediate-freuqncy signal with signal transition again.Between subreflector and tuner, be removably connected with guide frame, make installation and maintenance become convenient.
In above-mentioned composite type feed, described guide frame comprises feed pipe and gum cover, and described feed Guan Yiduan is detachably connected on the tuner, and the other end is detachably connected on the gum cover, and above-mentioned subreflector is detachably connected on the other end of gum cover.
In above-mentioned composite type feed; One end of said feed pipe has the shoulder block of protrusion, and the other end offers the groove one that is used to connect gum cover, offers step one and step two on the described gum cover on the madial wall at two ends respectively; Offer the groove two that is used to connect gum cover on the above-mentioned subreflector; Described feed Guan Yiduan is set on the above-mentioned tuner, and gum cover one end is arranged in the groove one of the feed pipe other end, and the step one of gum cover acts in the groove one; The other end of gum cover is arranged in the groove two of subreflector, and the step two of gum cover acts in the groove two.Through such structure, make that gum cover is dismountable to be connected between feed pipe and the subreflector.
In above-mentioned composite type feed, the shoulder block of said feed pipe is through being bolted on the above-mentioned parabolic antenna.
In above-mentioned composite type feed, described gum cover adopts teflon material to process.The gum cover of processing through teflon material has good elasticity, makes things convenient for gum cover to link to each other with subreflector with the feed pipe.
Compared with prior art, this composite type feed is connected feed pipe, gum cover and subreflector on the parabolic antenna through dismountable mode, reasonable in design, install/easy to maintenance, practicality is better.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of feed pipe.
Fig. 3 is the structural representation of gum cover.
Fig. 4 is the structural representation of subreflector.
Among the figure, 1, parabolic antenna; 2, tuner; 3, subreflector; 31, groove two; 4, feed pipe; 41, groove one; 42, shoulder block; 5, gum cover; 51, step one; 52, step two.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1; A kind of composite type feed; Comprise parabolic antenna 1, tuner 2 and subreflector 3, between subreflector 3 and tuner 2, be provided with feed pipe 4 and gum cover 5, described feed pipe 4 one ends are detachably connected on the tuner 2; The other end is detachably connected on the gum cover 5, and above-mentioned subreflector 3 is detachably connected on the other end of gum cover 5.
Extremely shown in Figure 4 like Fig. 2; One end of feed pipe 4 has the shoulder block 42 of protrusion, and the other end offers the groove 1 that is used to connect gum cover 5, offers step 1 and step 2 52 on the described gum cover 5 on the madial wall at two ends respectively; Offer the groove 2 31 that is used to connect gum cover 5 on the above-mentioned subreflector 3; Described feed pipe 4 one ends are set on the above-mentioned tuner 2, and gum cover 5 one ends are arranged in the groove 1 of feed pipe 4 other ends, and the step 1 of gum cover 5 acts in the groove 1; The other end of gum cover 5 is arranged in the groove 2 31 of subreflector 3, and the step 2 52 of gum cover 5 acts in the groove 2 31.Through such structure, make gum cover 5 dismountable being connected between feed pipe 4 and the subreflector 3.
In the present embodiment, the shoulder block 42 of feed pipe 4 is fixed on whole feed pipe 4 on the parabolic antenna 1 through bolt, and what feed pipe 4 can be firm like this links to each other with parabolic antenna 1; Simultaneously; When needs overhaul, also can feed pipe 4 be disassembled from parabolic antenna 1 through turning on bolt.Gum cover 5 adopts teflon material to process; The gum cover of processing through teflon material 5 has good heat endurance, low-friction coefficient, moisture resistance, mar proof, corrosion resistance; Make things convenient for gum cover 5 to link to each other with subreflector 3 with feed pipe 4; Can in the hot environment after parabolic antenna 1 focuses on, use, be not easy to be corroded or to be out of shape.
Penetrate the signal that comes from satellite and be mapped on the parabolic antenna 1, behind parabolic antenna 1 reflected signal, its focus is positioned at subreflector 3 positions; After subreflector 3 reflects signal once more; Get into feed pipe 4,, can part not reflexed to subreflector 3 to the signal of feed pipe 4 anyway again because feed pipe 4 front ends are the feed dish; Subreflector 3 is secondary reflection again, until signal reflex is arrived in the feed pipe 4.The signal that gets in the feed pipe 4 will receive processing signals by feed pipe 4 terminal tuners 2, and tuner 2 becomes intermediate-freuqncy signal with signal transition again.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
