The invention discloses an audible and visual alarm device for an elevator. The device comprises a fireproof cover of a transparent structure, a mounting opening is formed in the outer wall of the topof the fireproof cover, a heat preservation pipe of a transparent structure is sleeved with the inner wall of the mounting opening, the bottom end of the heat preservation pipe is welded to the innerwall of the bottom of the fireproof cover, the outer wall of the top end of the heat preservation pipe is sleeved with a mounting ring, a smoke sensor and an audible and visual alarm are sequentiallyand fixedly connected to the inner walls, located on the two sides of the heat preservation pipe, of the top of the fireproof cover, the inner wall of the lower portion of the heat preservation pipeis sleeved with a mounting plate, a camera is connected to the outer wall of the bottom of the mounting plate through bolts, and a controller, an execution element and a circuit breaker are sequentially connected to the outer wall of the top of the mounting plate. According to the audible and visual alarm device, the smoke sensor and the audible and visual alarm can be prevented from being burnt out by fire, meanwhile, the work of the smoke sensor is not hindered, and heat generated during the operation of the camera can be dissipated, so that the service life of the camera is prolonged, powerfailure can be timely achieved, the safety is improved, and meanwhile, the loss can be reduced.
本发明公开了一种电梯用声光报警装置,包括透明结构的防火罩,所述防火罩顶部外壁上开有安装口,且安装口内壁上套接有透明结构的保温管,所述保温管底端焊接于防火罩底部内壁上,所述保温管顶端外壁上套接有安装环,所述防火罩顶部位于保温管两侧的内壁上依次固定连接有烟雾传感器和声光报警器,所述保温管下部内壁上套接有安装板,且安装板底部外壁上通过螺栓连接有摄像头,所述安装板顶部外壁上依次连接有控制器、执行元件和断电器。本发明能够防止烟雾传感器和声光报警器被火烧坏同时不会妨碍烟雾传感器工作,能够将摄像头运行时产生的热量散发出去,提高了摄像头的使用寿命,能够及时的断电,提高了安全性的同时能够降低损失。
