A flexible air duct control device that automatically adjusts the ventilation volume

Abstract

The invention proposes a flexible air duct control device that automatically adjusts the ventilation volume, including a static pressure box, a hard pipe interface, a flexible air duct, a snap ring, a spout, a fixed component, a power component and a control mechanism. The flexible air duct is sleeved on the hard pipe interface and locked by a snap ring, and the nozzles are equally spaced on the flexible air duct. The fixed components include lifting rings, round hole sleeves, pulleys and connecting buttons, and the power components include thin steel wire ropes, windshields and driving mechanisms; the lifting rings are suspended under the floor or other components to ensure the straightness of the flexible air duct, and the round hole sleeves are fixed on the flexible The air duct is uniformly biased to one side of the static pressure box and has a certain distance from the nozzle. The pulley is fixed on the upper end of the round hole sleeve, the connecting button is installed on the upper part of the flexible air duct, and one end of the thin steel wire rope is fixed on the windshield through the connecting button. The upper end of the windshield is used to control the windshield, and the other end is connected to the mobile platform in the driving mechanism through a pulley. The windshield is installed on one side inside the spout, and the driving mechanism is controlled by the control mechanism to drive the thin wire rope to pull the windshield. The invention regulates the opening degree of the air outlet of the nozzle by controlling the position of the windshield, so as to achieve the function of automatically adjusting the ventilation volume.

Description

technical field [0001] The invention relates to the field of ventilation equipment, in particular to a flexible air duct control device for automatically adjusting ventilation volume. Background technique [0002] Ventilation is a technology that uses natural or mechanical methods to make the wind pass through without hindrance, and reach the room or sealed environment, so as to create a hygienic, safe and other suitable air environment. [0003] The flexible air duct has the characteristics of uniform and comfortable air supply, no blowing feeling, quiet and silent, light weight, flexible layout, convenient installation and maintenance, etc., and can attach a small amount of air volume to the duct wall through its micro-permeability (5% to 10%) The outer side forms an air film to avoid the possibility of "condensation" in summer conditions, and at the same time adds good insulation performance, which can be used for air supply in specific target areas. It is widely used in...

Problems solved by technology

[0004] However, some ventilation devices on the market are more about adjusting the ventilation speed to a certain extent, and are lacking in the automatic adjustment of the ventilation volume. In some industrial plants, it is difficult to achieve local precise control requirements.
