Abstract

The invention discloses a portable power-free communication manhole efficient ventilation method. The method comprises following steps: opening the communication manhole first before a constructor goes down the manhole for operation; checking whether harmful ingredients are contained in the manhole or not by using a gas detector; using a portable communication manhole efficient ventilator to discharge underground toxic harmful gas; using a toxic harmful gas detector again to make sure it is safe or not; allowing the operator to go down the manhole after safety is determined. The method has high ventilation efficiency and allows the toxic harmful gas to be quickly and forcibly discharged; two optional working modes are provided, and the toxic harmful gas can be automatically discharged using natural wind and also by manual operation.

Description

technical field [0001] The invention relates to a method for forced ventilation of a communication man well, in particular to the rapid forced discharge of poisonous and harmful gases in man wells often encountered in the professional construction of communication lines and pipelines, so as to avoid personal injury accidents. The invention can also be used for fast and forced discharge of poisonous and harmful gases in other small underground tube wells. It belongs to the field of mechanical technology. Background technique [0002] With the advent of the era of big data, the demand for communication network bandwidth has promoted the country's increase in investment in communication infrastructure. In recent years, the amount of communication line engineering has been huge. In the professional construction process of communication lines and pipelines, construction workers often need to go down to the communication wells below the ground for construction work.
