Abstract
The utility model discloses an automatic antenna protection cover, which comprises a semi-spherical protection cover body and two accommodating grooves, wherein the two accommodating grooves are used for storing the protection cover body, are of arc shapes, and are symmetrically arranged, one end of each accommodating groove is provided with a sensor, and the sensors are electrically connected with the accommodating grooves. The automatic antenna protection cover can automatically sense rainwater or high-temperature weather by the sensors, when rainwater or high-temperature weather is sensed, the protection cover body in the accommodating grooves automatically opens so as to protect an antenna and prevent influence of severe weather such as rainwater, high temperature and the like on an antenna body, and the service life of the antenna is greatly improved.
Description
Technical field
The utility model relates to field of antenna, particularly relates to a kind of self-action antenna shield.
Background technology
Antenna is a kind of converter, and it is transformed into the electromagnetic wave of propagating to the guided wave of transmission above-the-line promotion in unbounded medium (normally free space), perhaps carry out opposite conversion.In wireless device, be used for emission or receive electromagnetic parts.The engineering systems such as radio communication, broadcasting, TV, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, every electromagnetic wave that utilizes comes transmission of information, all relies on antenna to carry out work.In addition, aspect electromagnetic wave transmission energy, the energy emission of non-signal also needs antenna.General antenna all has invertibity, namely both can be used as transmitting antenna with common antenna, also can be used as reception antenna.The same antenna is identical as the fundamental characteristics parameter of emission or reception.The reciprocity theorem of Here it is antenna.
Be used for outdoor antenna, easily be subject to outside adverse circumstances impact, as: sleet, hail, the strong meetings such as sunlight cause long-term impact to exterior aerial, affect radiation characteristic and the circuit characteristic of antenna, the useful life of having reduced antenna.
The utility model content
The technical problem that the utility model mainly solves provide a kind of simple in structure, protection effect good, long service life, can prevent that exterior aerial is subject to the self-action antenna shield of high temperature, rainwater, corrosion.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of self-action antenna shield is provided, comprise the folding and unfolding groove that is hemispheric protective cover body and is used for the retractable protective canopy body, described folding and unfolding groove is two, the folding and unfolding groove is circular arc, two folding and unfolding grooves are symmetrical arranged, and described folding and unfolding groove one end is provided with transducer, and described transducer is electrically connected with the folding and unfolding groove.
In preferred embodiment of the utility model, described transducer is temperature sensor.
In preferred embodiment of the utility model, described transducer is rain sensor.
In preferred embodiment of the utility model, described protective cover body end is provided with sealing ring.
In preferred embodiment of the utility model, described protective cover body is fiberglass.
The beneficial effects of the utility model are: the utility model self-action antenna shield can be responded to rainwater or hot weather automatically by transducer, when sensing rainwater or hot weather, protective cover body in the folding and unfolding groove is opened automatically, thereby antenna is protected, prevent that the bad weathers such as rainwater, high temperature from exerting an influence to antenna body, improved the useful life of antenna greatly.
Description of drawings
Fig. 1 is the perspective view of the utility model self-action antenna shield one preferred embodiment;
Fig. 2 is the vertical view of Fig. 1;
The mark of each parts is as follows in the accompanying drawing: 1, protective cover body, 2, the folding and unfolding groove, 3, transducer, 4, sealing ring.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
See also Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of self-action antenna shield, comprise the folding and unfolding groove 2 that is hemispheric protective cover body 1 and is used for retractable protective canopy body 1, described folding and unfolding groove 2 is two, folding and unfolding groove 2 is circular arc, two folding and unfolding grooves 2 are symmetrical arranged, described folding and unfolding groove 2 one ends are provided with transducer 3, and described transducer 3 is electrically connected with folding and unfolding groove 2.
Described transducer 3 is temperature sensor, and when temperature sensor senses arrived high temperature, protective cover body 1 was opened automatically, can prevent that high temperature from exerting an influence to antenna, and when temperature reduced, protective cover body 1 automatic deploying and retracting was in folding and unfolding groove 2.
Described transducer 3 is rain sensor, and when raining, protective cover body 1 is opened automatically, can prevent that rainwater from exerting an influence to antenna, and in the rain stopping time, protective cover body 1 automatic deploying and retracting is in folding and unfolding groove 2.
Described protective cover body 1 end is provided with sealing ring 4, and when two protective cover body 1 merged, sealing ring 4 can play good sealing effectiveness, prevents that rainwater from entering in the protective cover.
Described protective cover body 1 is fiberglass, and is lightweight, intensity is high, has preferably decay resistance, long service life.
Compared with prior art, the utility model self-action antenna shield can be responded to rainwater or hot weather automatically by transducer 3, when sensing rainwater or hot weather, protective cover body 1 in the folding and unfolding groove 2 is opened automatically, thereby antenna is protected, prevent that the bad weathers such as rainwater, high temperature from exerting an influence to antenna body, improved the useful life of antenna greatly.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
