Long-distance transmission device for fire alarm

Abstract

The invention relates to the technical field of fire fighting, and discloses a long-distance transmission device for fire alarm, which comprises a lower box body, an upper box body is arranged at the top of the hollow part of the lower box body, a partition plate is fixedly connected to the inner wall of the joint of the lower box body and the upper box body, and a suction pump is fixedly mounted at the center of the top of the partition plate. A smoke alarm is fixedly installed in the center of the top of the upper box body, and air suction holes distributed in an annular array mode are formed in the annular outer wall of the top of the upper box body. According to the long-distance transmission device for fire alarm, the lower box body moves directionally in a shopping mall, the suction pump sucks air in the shopping mall into a cavity of the lower box body through an air suction pipe, a suction cover and an air suction hole, a smoke alarm detects the air, and a data transmission device feeds back detected signals to a background to achieve the purpose of long-distance transmission of the fire alarm. According to the invention, the long-distance transmission efficiency of the fire alarm in the shopping mall is improved, and the purpose of detecting the fire alarm in the shopping mall in real time for 24 hours is achieved.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a long-distance transmission device for fire alarm. Background technique [0002] Multi-station fixed-point fire prevention and alarm devices are often used in large shopping malls. When the detection device detects a fire, the transmission device will transmit the dangerous model to the background for corresponding processing. The fire alarm long-distance transmission device of the prior art is generally fixedly installed on the roof of each floor of the shopping mall, which cannot perform directional mobile monitoring, and the fire alarm device of the prior art has a single function and cannot filter the detected air , humidification, etc., so it cannot keep up with the needs of contemporary social development. Therefore, in view of the above problems, it is urgent to propose a long-distance transmission device for fire alarm. Contents of the invention [0003] (1) ...
