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.
本发明公开了一种双模防护系统,属于隔离帐结构及防护技术领域。双模防护系统包括隔离帐、支架、正负压空气净化过滤装置、正负压切换单元,所述支架用于将所述隔离帐撑起,使之与地面或单独形成隔离空间,正负压过滤装置空气净化模块、风机和控制模块,正负压切换单元包括进风风道、出风风道和三通阀门,正负压空气净化过滤装置用于抽气并过滤空气,正负压切换单元可以实现隔离舱内正负压的切换,使得隔离帐内部形成正压或负压隔离防护空间。正负压隔离帐的使用,为人们复产和复工乘坐交通工具提供了安全保障,解决不同使用环境对隔离帐的不同要求,提高了隔离帐的利用率。
