Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0032] A positive pressure underground work well safety protection work system, including a combined small space work shed 19, a single air circulation system in the positive pressure work well, a non-contact multifunctional explosion-proof, moisture-proof and shadowless lighting system, a toxic and harmful gas monitoring and alarm system, and a work area. Well water collection and utilization system.

[0033] The main frame of the combined small space shed 19 is an assembled cubic frame structure. The top, bottom and four walls of the combined small space shed are respectively composed of separate fire-resistant fabrics. In this way, it can be assembled and disassembled at the work site very conveni...

Abstract

The invention relates to a positive-pressure underground working-well safety protection work system and an arranging method thereof. The system comprises a combination type small-space work shed, a positive-pressure working-well inner-air single circulation system, a multifunctional non-contact anti-explosion and anti-damp shadowless lighting system, a hazardous gas monitoring and alarming system and a working-well inner-accumulated-water collecting and using system. The system comprises the positive-pressure working-well inner-air single circulation system, the hazardous gas monitoring, alarming and exhausting system, the non-contact anti-explosion and anti-damp shadowless lighting system, the working-well inner-accumulated-water collecting and using system and the like so that the work environment of workers in a working well can be guaranteed well, and therefore safety of underground workers is effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of electric power construction, and relates to a work shed used when people work in a confined space, in particular to a positive pressure underground well safety protection work system and a setting method thereof. Background technique [0002] At present, most of the urban public power systems, communication systems, and pipe network systems have basically realized underground deployment. So that creates a lot of facility maintenance worker wells. These working wells belong to the confined working space. The entrance and exit are narrow and the air circulation is not smooth. Due to the decomposition of organic matter in pipelines and industrial wells, a large amount of toxic and harmful gases will be produced, especially in the urban gas supply network and drainage system, which either directly transport flammable gases; or decompose and produce a large amount of toxic gases. harmful gas. Due to the continuous i...
