Abstract
The utility model relates to an air defense warning device, which consists of a casing body, a wind wheel, a permanent-magnet direct current motor, and a transformer rectifier. A sound barrier plate is arranged on the upper surface of the casing body, a wind column is arranged on the lower surface of the sound barrier plate, and the wind wheel is arranged in the wind column. The utility model is characterized in that the permanent-magnet direct current motor arranged at the middle part of the casing body and the wind wheel are coaxial, the transformer rectifier is arranged in the bottom seat of the casing body, and the alternating current input connector of a junction box arranged on the casing body is directly connected with the middle line of the permanent-magnet direct current motor. The utility model has the advantages that the volume is small, the weight is light, the installation and the maintenance are easy, the service life is long, the utility model is anti-destroying and anti-interference, the sound has the terror feeling greatly, the shaking power is strong, the performance is good, and the multiple warnings can be realized under the power turn-off condition during the war.
Description
Technical field
The utility model relates to a kind of air defence warning device.
Technical background
Existing air defence warning device mainly contains two kinds of motor siren and electroacoustic warning horns.What motor siren used is three-phase alternating current, and what the small part use was also arranged is single-phase alternating current, but this warning horn sound pressure level is low, weak effect.The fatal shortcoming of warning horn of using three-phase or single-phase alternating current is can't implement to report to the police when cutting off the power supply wartime, does not meet the modern war characteristics.
Summary of the invention
The purpose of this utility model is to provide a kind of two kinds of power supplys of AC and DC that are applicable to, adapts to the wide air defence warning device of occasion.
The purpose of this utility model is achieved in that a kind of antiaircraft alarm, by housing, wind wheel, permanent magnet direct current motor, vertoro is formed, be provided with sound baffle above the housing, below sound baffle, be provided with air duct, wind wheel is located in the air duct, it is characterized in that: the permanent magnet direct current motor that is located at the housing middle part is coaxial with wind wheel, vertoro is located in the base of housing, the alternating current input adapter that is located at the terminal box on the housing is connected with the permanent magnet direct current motor circuit by vertoro, and the direct current input adapter of terminal box directly is connected with the permanent magnet direct current motor circuit.
The utlity model has following advantage: little, in light weight, the easy installation and maintenance of volume, long service life, anti-ruin, anti-interference, the sound has feeling of terror, impact is strong, performance is good, wartime following of alternating current powering-off state can realize repeatedly reporting to the police.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail: sound baffle 1, wind wheel 2, air duct 3, permanent magnet direct current motor 4, vertoro 5, terminal box 6, base 7, housing 8.As shown in the figure, a kind of antiaircraft alarm, by housing 8, wind wheel 2, permanent magnet direct current motor 4, vertoro 5 is formed, be provided with sound baffle 1 above the housing 8, below sound baffle 1, be provided with air duct 3, wind wheel 2 is located in the air duct 3, it is characterized in that: the permanent magnet direct current motor 4 that is located at housing 8 middle parts is coaxial with wind wheel 2, vertoro 5 is located in the base 7 of housing 8, the alternating current input adapter that is located at the terminal box 6 on the housing 8 is connected with permanent magnet direct current motor 4 circuits by vertoro 5, and the direct current input adapter of terminal box 6 directly is connected with permanent magnet direct current motor 4 circuits.External communication electricity or direct current are imported by terminal box, if direct current is then directly supplied with permanent magnet direct current motor work; If alternating current then is rectified into 48 volts of direct currents by vertoro, supply with permanent magnet direct current motor work.Permanent magnet direct current motor and wind wheel are coaxial, when high speed rotating that it changes with per minute 6500 to 7000, drive wind wheel and sound the alarm by the pronunciation window on the air duct.Air duct, permanent magnet direct current motor shell, base link to each other with screw.Outside direct current 48 overhead accumulator power supplys and 220 volts of power supplys of external communication can not be powered simultaneously.
