The invention discloses a top exhaust device for a fabricated elevator. The device comprises a fixed base and a fixed shell, wherein four through holes are symmetrically formed in the upper surface ofthe fixed base, a concave groove is integrally formed in the front surface of the fixed base, and a rectangular groove is integrally formed in the front portion of the upper surface of the fixed base. Through mutual cooperation of an infrared sensor, an LED lamp body and a photoresistor, when the pedestrian volume is large, the infrared sensor detects a large amount of heat radiation, and signaloutput to the LED lamp body is increased, so that the power of the LED lamp body is increased, the brightness of the LED lamp body is higher, the resistance is automatically adjusted to become smallerafter the brightness is received by the photoresistor, the output power of the motor for an exhaust fan becomes higher, and the high-power exhaust requirement under the condition that the pedestrianvolume is large is met; when the pedestrian volume is small, the output power of the motor for the exhaust fan becomes lower; and when no person exists, the infrared sensor cannot detect the heat radiation, so that the motor stops running, and the corresponding requirement for saving resources is met.
本发明公开了一种用于装配式电梯的顶部排风装置,包括固定基座和固定壳体,所述固定基座的上表面对称开设有四个通孔,所述固定基座的前表面一体成型有凹合槽,所述固定基座的上表面前部一体成型有矩槽;通过红外传感器、LED灯体和光敏电阻的互相配合,当人流量较多时,红外传感器检测到大量热辐射,加大对LED灯体的信号输出,使得LED灯体的功率变大,亮度更高,亮度被光敏电阻接收后则电阻自动调节变小,使得电机对排气扇的输出功率变得更大,满足人流量较多的情况下的大功率排气需求;而当人流量较小,则电机对排气扇的输出功率变得更小;而当没有人时,红外传感器无法检测到热辐射,则使得电机暂停运行,达到相应节省资源的需求。
