The radio magnetic wave come is penetrated, and microwave receiver is sent to by feeder line.
With the development of microwave communication, the working frequency of microwave communication is higher and higher, and for the weight of microwave telecommunication system
It wants for component part microwave antenna, gain is also higher and higher, and corresponding half-power angle is also smaller and smaller.Under normal circumstances, micro-
When being under pressure, transmission direction can shift wave antenna, but when half-power angle do not have it is small to a certain extent when, have no effect on
The normal operation of microwave communication；And when half-power angle it is small to a certain extent when, the power in transmission direction is made due to offset
It can decay quickly, it is easy to influence the normal operation of microwave communication.And be most susceptible in microwave antenna real work
Pressure just comes from the natural causes such as sleet, and especially accumulated snow influences even more serious for caused by microwave antenna.So working as microwave
The gain of antenna is very high, when half-power angle very little, then needs a kind of equipment to eliminate the natural causes such as accumulated snow for microwave antenna
Influence, but the safeguard of general microwave antenna is the form directlyed adopt in the top fixed baffle of microwave antenna, but
It is that cannot very easily be packed up in the case where weather is good, it is often necessary to manually remove, therefore more time-consuming and laborious.
Therefore be badly in need of it is a kind of can not only play good protection effect for microwave antenna, and more convenient micro- of folding and unfolding
Wave antenna shield.
Utility model content
The purpose of the utility model is to provide a kind of microwave antenna shields, microwave antenna can not only be played very well
Protection effect, and folding and unfolding is more convenient.
The utility model provides the following technical solution:
A kind of microwave antenna shield, including shield body, shield body include being arranged right above microwave antenna
Protective plate, the projection of microwave antenna on the ground are fallen in the range of protective plate projects on the ground, and shield body passes through company
Fitting is fixed on the pole of microwave antenna, and shield body further includes connecting rod, the directive wheel that connecting rod one end is arranged in and position
Electric block above directive wheel, connector include fixed link, the sleeve being set in fixed link and connection sleeve and prevent
The connecting rod of backplate, fixed ring of the protective plate on connecting rod side, the other end and electric block of connecting rod are each attached to
On the pole of microwave antenna, and the lifting rope of electric block passes through directive wheel and is connected with fixed ring.
Preferably, protective plate is hollow heat-conducting plate, and insulated column, the electric heating being wrapped on insulated column are equipped in protective plate
Silk, heating wire are filled with insulator outside, and heating wire and insulator are encapsulated in the hollow cavity of protective plate, the both ends of insulated column
Equipped with insulating end, the binding post of heating wire one end passes through insulating end and is connected with power supply, so that after heating wire is powered, so that
Accelerate accumulated snow and the thawing fallen on protective plate, reduces the weight bearing of protective plate.
Preferably, insulator is magnesia powder.
Preferably, the lower end of fixed link is also connected with the positive stop strip being laterally arranged, and the bottom of protective plate is arranged in positive stop strip,
Allow to prevent that protective plate rotation is excessive.
The beneficial effects of the utility model are: one end of the lifting rope of electric block is in directive wheel by starting electric block
Position-limiting action under, realize protective plate surround fixed link rotation, when snowy day, can by by protective plate transverse gear micro-
The top of wave antenna realizes that one end of protective plate can be promoted by protection for microwave antenna after snow stops, realization for
Protective plate is collected.
