Method and device for regulating air pressure in an ultra-high-speed elevator shaft

Abstract

The present application discloses a method for adjusting the air pressure in the shaft of an ultra-high-speed elevator, which uses a forced ventilation pressure regulating device to adjust the air pressure in the shaft. Adjust the parameters to control the flow and airflow direction of the forced ventilation pressure regulating device, and adjust the air pressure in the shaft. The application also discloses an ultra-high-speed elevator hoistway air pressure regulating device, including a controller, a hoistway air pressure monitoring device, and a forced ventilation pressure regulating device; Parameters to control the forced ventilation pressure regulating device to adjust the air pressure in the well by sending air to the well or extracting air. The application can save the building opening cost, adapt to the actual situation of the building and seasonal changes, improve the noise and air pressure of the car, and improve the phenomenon of insufficient self-closing force of the landing door.

Description

technical field [0001] The present application relates to the field of air pressure regulation of ultra-high-speed elevator shafts, and in particular, to a method and device for air pressure regulation of ultra-high-speed elevator shafts. Background technique [0002] At present, in the field of ultra-high-speed elevator technology, the problems such as poor car comfort and insufficient self-closing force of the landing door caused by the wind pressure in the hoistway are all solved by opening a fixed area of ​​ventilation holes in the hoistway, such as figure 1 shown. Major elevator manufacturers will calculate the area of ​​hoistway vents according to their own calculation formulas, including hoistway plunger ratio and elevator speed. [0003] Taking an elevator manufacturer as an example, the size and position of the vent opening are briefly described as follows: when the speed is 4m / s≤ν≤6m / s, opening the vent can effectively reduce the noise in the car and improve the r...

Problems solved by technology

[0004] Problems and disadvantages of the prior art: due to the fixed area of ​​the vent, the temperature and humidity in the well vary in different seasons, resulting in obvious differences in the effect of the vent due to seasonal changes, which affects the comfort of the ride; in addition, the calculation formula of the well vent The vent area shown can only be used as a reference. Due to the influence of the building environment, the actual on-site effect is uncertain. If the ventilation area of ​​the hoistway is too small, it will affect the comfort in the car and the noise outside the hall. It will be more difficult to rectify the building body again. ; Due to the limitation of the building body, if the ventilation openings with a total area of ​​sufficient area are set according to the design requirements of the elevator manufacturer, the construction cost will be increased

However, the adjustment of the size of the vent area is passive and lagging behind the adjustment of the hoistway air pressure; the effect of reducing the noise in the car is also limited. When the opening area reaches a certain size, the opening area becomes larger, and the noise value in the car does not will continue to get smaller, and the effect of reducing car shaking will no longer increase

In addition, this invention does not solve the problem of increased construction costs caused by opening large-area vents, and the difficulty of rectification in the later stage
