Description

Technical Field

[0001] The invention relates to the field of motors and smoke exhaust, and in particular to an energy-saving automatic smoke exhaust motor. Background Art

[0002] The energy-saving automatic smoke exhaust motor is an innovative smoke exhaust equipment that combines thermal energy conversion technology, energy storage technology and intelligent control technology. The core of this motor is that it can convert the thermal energy in the environment into mechanical energy and store it for use by the smoke exhaust fan when needed. This not only greatly reduces the energy consumption of the smoke exhaust system, but also enables the smoke exhaust system to work normally without relying on external electricity. The energy-saving automatic smoke exhaust motor is also equipped with an intelligent control device, which can automatically adjust the operating state of the smoke exhaust fan according to the ambient smoke concentration. When the smoke concentration reaches a certain level, the control device will automatically start the smoke exhaust fan and use the stored energy to drive its operation; when the smoke concentration decreases, the control device will reduce the operating power of the smoke exhaust fan or stop it accordingly, thereby achieving energy saving and automatic control. In summary, the energy-saving automatic smoke exhaust motor is an efficient, energy-saving and intelligent smoke exhaust equipment, which is of great significance to improving building safety and reducing energy consumption.

[0003] After massive searches, it was found that the prior art publication number is CN106870406A, which discloses a new type of fire-fighting fan. The smoke inlet of the new type of fire-fighting fan can be disassembled, an elbow can be installed, and the smoke pipe can be lengthened (shortened) to meet the installation requirements in different environments. A controller is installed on the base to save space. A motor protection cover is provided on the outside of the motor. This arrangement can prevent the fire-fighting fan from working in a harsh working environment, protect the motor, and greatly improve the service life of the fire-fighting fan. When there is a fire, the alarm will sound an alarm to remind indoor personnel to pay attention to the fire and evacuate in time, and start the fire-fighting fan through intelligent control. The new type of fire-fighting fan is scientifically and reasonably designed, simple in structure, and highly intelligent. It greatly improves the smoke exhaust efficiency of the equipment and solves the problems of the existing fire-fighting fans, which are single in function, cannot be used in different environmental locations, are inconvenient to install, are easily damaged in high temperature environments, need to be started manually, are inefficient, cannot provide early warning, and provide limited favorable conditions for rescue and firefighting.
