Anti-theft alarm device of inspection well cover
The invention discloses an anti-theft alarm device of an inspection well cover. The anti-theft alarm device comprises a magnet detection device and a controller which are installed on a well wall. The magnet detection device comprises a fixing ring and a magnet moving part; the fixing ring is used for fixing the inspection well cover; an insulating fixing buckle is arranged on the inner side of the fixing ring, and a through hole is formed in the insulating fixing buckle; the magnet moving part comprises a plastic cylinder, a round powerful magnet, a bottom conductive block and a metal connecting frame; the round powerful magnet is arranged at the top of the plastic cylinder; the bottom conductive block is arranged at the bottom of the plastic cylinder; the metal connecting frame is arranged at the position, corresponding to the lower portion of the bottom conductive block, of the inner side wall of the fixing ring; the bottom conductive block and the metal connecting frame are electrically connected with the controller; when the inspection well cover is closed, the circular powerful magnet tightly attracts the inspection well cover, the bottom conductive block is lifted, and at the moment, a circuit is in a switched-off state; and when the inspection well cover is lost, the bottom conductive block falls down and contacts with the metal connecting frame to switch on the circuit, a sound-light alarm is triggered, and alarm information is sent remotely.
本发明一种窨井盖的防盗报警装置,包括安装于井壁上的磁铁检测装置和控制器;磁铁检测装置包括固定环磁铁活动件;固定环的固定窨井盖;固定环内侧设有绝缘固定卡扣,绝缘固定卡扣设有通孔;磁铁活动件包括塑料圆柱体、圆形强力磁铁、底部导电块和金属连接框,圆形强力磁铁设置在塑料圆柱体的顶部,底部导电块设置在塑料圆柱体底部,金属连接框设置在固定环的内侧壁对应于底部导电块下方的位置上;底部导电块与金属连接框分别与控制器电连接,当窨井盖盖上时,圆形强力磁铁吸紧窨井盖,底部导电块被抬升,此时电路处于断开状态;当窨井盖缺失时,底部导电块落下,接触金属连接框后接通电路,触发声光报警,并远程发送报警信息。
