Abstract
The utility model discloses a cable work well ventilation detecting system which comprises a mine gas isolating device, an air supplying and inducing system, an illuminating system, a harmful gas monitoring and alarming system, a work environment safety monitoring system and a power supply system. The air supplying and inducing system is arranged on the upper portion of the mine gas isolating device, the work environment safety monitoring system is arranged inside the mine gas isolating device, the harmful gas monitoring and alarming system is arranged on the air supplying and inducing system, and the harmful gas monitoring and alarming system and the work environment safety monitoring system are electrically connected with the power supply system. According to the cable work well ventilation detecting system, work space and other space of a work well are isolated, automatic ventilation and intelligent gas composition monitoring can be achieved, and safe and innocuous air space is formed in the work space. The cable work well ventilation detecting system has the advantages of being simple in structure, convenient to mount, capable of being folded integrally, convenient to carry and transport, and capable of improving the reliability and the safety of a work environment.
Description
Technical field
The utility model relates to the auxiliary equipment of a kind of cable work well underground work, particularly a kind of cable work well ventilation detection system.
Background technology
The cable shaft operation belongs to Working in confined space, imports and exports narrow and smallly, and atmosphere draught-free or circulation are not smooth, and working space is narrow, improper ventilation and the easy place of initiation potential event.Due to organic decomposition reaction in water accumulation of pipeline, can produce a large amount of toxic and harmfuls, common are the toxic and harmfuls such as hydrogen sulfide, carbon monoxide, methane, anoxia asphyxia, this class pernicious gas is colourless, poor heat stability, the solubility with pressure decreased in water reduce, and volatility strengthens.Be difficult for finding in the construction operation process, once occur that poisoning symptom is often to the stage that can't save oneself, therefore, must and have gained some understanding to the harm of human body to its characteristic, just can accomplish good prevention.
At present, the cable work well is to adopt the axial flow ventilating fan, before going into the well, the staff covers the well head exhaust, stop air draft after a period of time, remove ventilating fan, staff's work of going into the well, but can pump in advance wind like this, can not pump wind in work, harmful working region that is diffused into of other parts in work in the work well, harm underground work personnel.Get angry during the narrow and small pyrocondensation joint of work well area and produce a large amount of hot gas in addition, consume a large amount of oxygen, the operating personnel is easily caused to anoxic.And existing gas controlling device is that single aspect accomplishes that gas detects, can not combine with the exhaust spacer assembly, be difficult to underground work personnel underground work and improve safe and reliable working environment.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of situation of testing environment, and the cable work well ventilation detection system of safe working environment is provided.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of cable work well ventilation detection system, comprise the mine gas spacer assembly, send induced draught system, illuminator, the monitoring harmful gases warning system, working environment safety monitoring system and electric power system, the described induced draught system that send is arranged at described mine gas spacer assembly top, described working environment safety monitoring system is arranged at described mine gas spacer assembly inside, described monitoring harmful gases warning system is arranged at described sending on induced draught system, described monitoring harmful gases warning system and described working environment safety monitoring system are electrically connected to described electric power system.
The cable work well ventilation detection system that the utility model provides, other spaces of isolation working space and work well, automatic ventilation and intellectual monitoring gas componant, form safe nontoxic air space at operation interval, have simple in structurely, easy for installation, integral body can be drawn in, be convenient to the carrying transportation, can improve the reliability and safety of working environment.
The accompanying drawing explanation
The schematic diagram of the cable work well ventilation detection system that Fig. 1 provides for the utility model;
The structural representation of the cable work well ventilation detection system that Fig. 2 provides for the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of cable work well ventilation detection system of the present utility model, comprise mine gas spacer assembly 1, send induced draught system 2, illuminator 3, monitoring harmful gases warning system 4, working environment safety monitoring system 5 and electric power system 6, the described induced draught system 2 that send is arranged at described mine gas spacer assembly 1 top, described working environment safety monitoring system 5 is arranged at described mine gas spacer assembly 1 inside, described monitoring harmful gases warning system 4 is arranged at described sending on induced draught system 2, described monitoring harmful gases warning system 4 and described working environment safety monitoring system 5 are electrically connected to described electric power system 6.
The specific works mode of the cable work well ventilation detection system that the utility model provides is as follows:
Mine gas spacer assembly 1 is opened in work well inside, and will send induced draught system 2, illuminator 3, monitoring harmful gases warning system 4, working environment safety monitoring system 5 etc. to be connected unlatching with electric power system 6, the staff goes into the well and carries out work afterwards, after end-of-job, at aboveground recovery said apparatus, get final product.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but within this embodiment is included in scope of the present utility model.
