Problems solved by technology

For medium and low-speed elevators, due to the low speed, there will be no wind noise. This design can meet the requirements, but for high-speed elevators, when the elevator runs at high speed, one of the shortcomings is that the airflow will flow from the ventilation holes. Entering and exiting the car quickly will inevitably cause wind noise, which will affect the comfort of the elevator

Embodiment Construction

[0009] Such as figure 1 Shown, a kind of protective cover device that reduces the wind noise of the front vertical plate of elevator car, comprises the front vertical plate 1 of elevator car, is equipped with ventilating hole 11 on the front vertical plate 1, in the present invention, described front vertical plate The outside of the car of the plate 1 is fixed with an outer cover plate 2 that blocks the area of ​​the ventilation hole 11, and the outer cover plate 2 is provided with an air inlet 21. The outer cover plate 2 is fully sealed except for the upper and lower openings, and at the same time, there is enough space between the front vertical plate 1 and the outer cover plate 2. Due to the shielding of the outer cover plate 2, the air can only flow from the air inlet 21 on the outer cover plate 2. The ventilation holes 11 of the front vertical panel 1 are detoured into without directly generating a strong air flow, thereby reducing the wind noise caused by the ventilatio...

Abstract

The invention discloses a protective cover device for reducing wind noise of a front vertical plate of a car of an elevator. The protective cover device comprises the front vertical plate with the car of the elevator. Vent holes are distributed in the front vertical plate. An outer cover plate used for shielding the areas of the vent holes is fixed to the outer side of the car of the front vertical plate. An air inlet is formed in the outer cover plate. Due to the fact that the outer cover plate is fixed to the outer side of the front vertical plate and the vent holes in the front vertical plate are shielded by the outer cover plate, air can enter the vent holes of the front vertical plate in a detoured manner only through the air inlet in the outer cover plate, no strong air flow can be directly generated, wind noise caused by the vent holes of the front vertical plate is reduced, and the effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a protective cover device capable of reducing wind noise on the front vertical plate of an elevator car. Background technique [0002] For high-speed elevators, especially high-speed elevators with a speed of more than 4 m / s, the elevator shafts are generally fully enclosed or partially enclosed shafts. The elevator runs up and down at high speed in the hoistway, like piston movement, it will inevitably generate strong airflow, the airflow will quickly enter and leave the car from various gaps in the car, causing the air pressure in the car to fluctuate, resulting in wind noise, causing headaches for passengers in the car Tinnitus, a feeling of discomfort. [0003] As we all know, for the elevator car, in order to make the passengers feel comfortable in the car, it must be well ventilated. According to the requirements of the GB7588 elevator standard: the car without holes sho...
