Dual-mode protection system

Abstract

The invention discloses a dual-mode protection system, and belongs to the technical field of isolation tent structures and protection. The dual-mode protection system comprises an isolation tent, a support, a positive and negative pressure air purification and filtration device, a positive and negative pressure switching unit, a positive and negative pressure air purification module, a fan and a control module, and the support is used for supporting the isolation tent to enable the isolation tent to form an isolation space with the ground or independently. The positive and negative pressure switching unit comprises an air inlet duct, an air outlet duct and a three-way valve, the positive and negative pressure air purifying and filtering device is used for exhausting air and filtering air, and the positive and negative pressure switching unit can realize switching of positive pressure and negative pressure in the isolation cabin, so that a positive pressure or negative pressure isolation protection space is formed in the isolation curtain. By using the positive and negative pressure isolation tent, the safety guarantee is provided for people to take traffic tools for reproducing and reworking, different requirements of different use environments on the isolation tent are met, and the utilization rate of the isolation tent is improved.

Description

technical field [0001] The invention relates to a dual-mode protection system, which belongs to the technical field of isolation protection and is used for establishing a positive pressure protection and negative pressure isolation environment in a specific space. Background technique [0002] In the face of epidemics and periodic outbreaks of viruses or influenza, people often adopt isolation methods to deal with them. After the epidemic eases, if isolation and prevention are not done well, it will often cause a new round of epidemics. During the easing of the epidemic and other mild infectious diseases, people still need to maintain normal production and life as conditions permit. It is difficult for people to resume production and work without taking subways, buses, airplanes and other means of transportation. Such public places It is often a closed space. If the protection is not in place, it is likely to cause a large-scale outbreak of the newly controlled epidemic. The...
