Monitoring device with smoke exhaust function for building automation

Abstract

The invention discloses a building automation monitoring device with a smoke discharge function, which comprises a smoke discharge box body, an air guide pipe and a baffle plate structure, outer connecting plates are mounted on two sides of the outside of the smoke discharge box body, electric telescopic rods are arranged at the bottoms of the outer connecting plates, the bottoms of the electric telescopic rods are fixed at the top of a ceiling, and the air guide pipe is arranged on the top of the smoke discharge box body. A smoke exhaust fan is installed on an output shaft of the first driving motor, a bottom net plate is arranged at the bottom of the smoke exhaust box body, the air guide pipe is arranged at the top of the smoke exhaust box body, and the baffle structure is arranged on the side face of the smoke exhaust box body. The monitoring device with the smoke exhaust function for building automation is provided with an outer connecting plate, an electric telescopic rod and a side net plate, the electric telescopic rod drives the smoke exhaust box body to ascend and descend through the outer connecting plate, and then when a smoke sensor detects a smoke signal, the electric telescopic rod shrinks, so that the smoke exhaust box body descends, and the side net plate on the side face of the smoke exhaust box body is exposed; therefore, the smoke suction area is increased, and the smoke exhaust efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of building automation, in particular to a monitoring device with smoke exhaust function for building automation. Background technique [0002] In modern construction projects, fire alarm systems are generally installed, but when a fire really comes, the pervasive smoke is the chief culprit of death. Among the people who died in the fire, the people who died of smoke accounted for The ratio is as high as 80%, so in the early stage of the fire, that is, when the firefighters arrive in the future, an effective smoke exhaust system will greatly increase the survival probability of the victims, so it is necessary to design smoke monitoring and smoke exhaust devices. [0003] However, in the existing smoke monitoring devices, most of them do not have a smoke exhaust component, and only generate an alarm for the smoke. Small, so that the smoke exhaust efficiency is low, so the existing structure needs to be impro...

Problems solved by technology

[0004] The purpose of the present invention is to provide a monitoring device with a smoke exhaust function for building automation, to solve the problem in the above-mentioned background technology that most of the existing smoke monitoring devices do not have a smoke exhaust component, and only produce smoke to the smoke. At the same time, in the existing smoke exhaust structure, most of them are fixedly installed on the ceiling, and the smoke absorption area is small, which makes the smoke exhaust efficiency low.
