The environment-friendly, energy-saving and noise-reducing elevator car comprises an elevator car body, sound insulation devices are arranged on the left side and the right side of the elevator car body correspondingly, flow guide plates are arranged on the outer sides of the sound insulation devices, and flow guide covers are arranged at the upper end and the lower end of the elevator car body correspondingly; the guide covers are arranged at the upper end and the lower end of the lift car, the guide plates are arranged on the two sides of the lift car, and the corresponding guide grooves are formed in the guide plates and the guide covers, so that when the lift car runs quickly, the guide grooves are beneficial to reducing vortexes and wind noise and improving the stability of the lift car in the running process; meanwhile, through the arrangement of an upper air inlet, a lower air inlet and a sound insulation ventilator, air is sucked through fast movement of the lift car, electric power is not needed, external air can enter the lift car, and air circulation in the lift car is promoted; in addition, a sound insulation device is arranged between the lift car and the flow guide plate, and the sound insulation effect is further improved.
Description
Technical field [0001] The present invention relates to the field of elevator technologies, and in particular, there is an environmentally friendly energy-saving noise reduction elevator car. Background technique [0002] The elevator runs in the wellway. With the increase in car speed, pneumatic problems such as aerodynamic noise will affect the safety and comfort of the elevator. The elevator noise is mainly caused by air resistance and mechanical vibration. The elevator produces a large wind resistant in the undulating, these resistances and the car have a wind resistance; in addition, due to the sharp increase in air flow rate, the airflow produces greatly separated and discontinuous vortices in the tail of the vanity. Continuous swirls continue to fall off and evolve the pressure in the eddy current field to produce dramatic fluctuations to generate eddy current noise. Many of the noise of the elevator is caused by vibration, which propagates in air, solid medium in the form...
