Description
Technical Field
[0001] The present invention relates to the fields of electric motors and smoke exhaust, and particularly to an energy-saving automatic smoke exhaust motor. Background Art
[0002] The energy-saving automatic smoke exhaust motor is an innovative smoke exhaust device that combines heat energy conversion technology, energy storage technology, and intelligent control technology. The core of this motor lies in its ability to convert the heat 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 operate normally without relying on external power. The energy-saving automatic smoke exhaust motor is also equipped with an intelligent control device that 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 drive its operation using the stored energy; when the smoke concentration decreases, the control device will correspondingly reduce the operating power of the smoke exhaust fan or stop its operation, thus achieving energy conservation and automatic control. In summary, the energy-saving automatic smoke exhaust motor is an efficient, energy-saving, and intelligent smoke exhaust device, which is of great significance for improving building safety and reducing energy consumption.
[0003] After a large amount of retrieval, it is found that the prior art publication number is CN106870406A, which discloses a new type of fire-fighting fan. For this new type of fire-fighting fan, the smoke inlet can be disassembled, an elbow can be installed, and the lengthening (shortening) smoke exhaust pipe can meet the installation in different environments. A controller is installed on the base, saving space. A motor protection cover is provided outside the motor, so that the fire-fighting fan can be prevented from working in a harsh working environment, protecting the motor and greatly improving the service life of the fire-fighting fan. When there is a fire, the alarm will sound an alarm to remind the indoor personnel to pay attention to the fire and evacuate and withdraw in time. And the fire-fighting fan is started to work through intelligent control. This new type of fire-fighting fan is scientifically and reasonably designed, has a simple structure, and a high degree of intelligence, greatly improving the smoke exhaust efficiency of the equipment, and solving the problems in the existing fire-fighting fans, such as single function, inability to meet the use in different environmental positions, inconvenient installation, easy damage in high-temperature environments, manual start required, low efficiency, inability to give early warning, and limited favorable conditions provided in rescue and fire-fighting.

The control circuit 9 determines whether to start the exhaust fan according to the received smoke concentration signal:
[0041] If it is necessary to start the exhaust fan 5, the control circuit 9 will control the energy storage device 3 to release the stored energy and supply it to the exhaust fan 5. The fan blade 10 is connected to the energy storage device 3 through the drive shaft 11 and uses the energy provided by the energy storage device 3 to exhaust smoke under the control of the control device 4, so that the energy-saving automatic exhaust motor of the present invention can drive the exhaust fan 5 to exhaust smoke by using the thermal energy in the environment without relying on external power, thus achieving the purpose of energy conservation and automatic smoke exhaust.
