Abstract
The utility model discloses an air exhausting and interchanging device of a cable well detection system. The air exhausting and interchanging device of the cable well detection system comprises an isolating tent. An air supply opening and an air outlet are formed in the upper surface of the isolating tent. The air exhausting and interchanging device of the cable well detection system further comprises an air supply device and an air inducing device which are respectively arranged on the isolating tent. The air supply device and the air supply opening are connected through an air supply pipe. The air inducing device is connected with the air outlet through an air inducing pipe. The exhausting and interchanging device of the cable well detection system guarantees the normal values of oxygen and the temperature in a well, improves the reliability and the safety of the working environment due to the arrangement of the air supply device and the air inducing device, and is easy to operate and convenient to use.
Description
Technical field
The utility model relates to a kind of Gong Jing security fields, particularly a kind of cable work well detection system exhaust ventilation device.
Background technology
The cable shaft operation belongs to Working in confined space, and so-called confined space refers to imports and exports narrow and small, atmosphere draught-free or circulation is 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.Existing cable work well array wind is to adopt the axial flow ventilating fan, before going into the well, the staff covers the well head exhaust, after a period of time, stop air draft, remove ventilating fan, staff's work of going into the well, but can pump in advance wind like this, in work, can not pump wind, 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.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of cable work well detection system exhaust ventilation device that can guarantee work personnel in the pit safety.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of cable work well detection system exhaust ventilation device, comprise that the described isolation tent of isolation tent upper surface is provided with air outlet and air outlet, also comprise the air-supply arrangement and the blower unit that are arranged at respectively on the isolation tent, described air-supply arrangement is connected by ajutage with described air outlet, and described blower unit is connected by induced duct with described air outlet.
This device also comprises for described air-supply arrangement is propped up to support overhead, and described support is arranged on described isolation tent, under described air-supply arrangement.
The height of described support is 500mm.
Between described air-supply arrangement and described blower unit, distance is more than or equal to 1000mm.
The cable work well detection system exhaust ventilation device that the utility model provides, by air-supply arrangement and blower unit are set, guarantee the normal value of the inner oxygen of work well and temperature, improves the reliability and safety of working environment, and is simple to operate, easy to use.
The accompanying drawing explanation
The structural representation of the cable work well detection system exhaust ventilation device that Fig. 1 provides for the utility model;
The rearview of the cable work well detection system exhaust ventilation device 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 detection system exhaust ventilation device that the utility model provides, comprise that described isolation tent 1 upper surface of isolation tent 1 is provided with air outlet 2 and air outlet 3, also comprise the air-supply arrangement 4 and the blower unit 5 that are arranged at respectively on isolation tent 1, described air-supply arrangement 4 is connected by ventilation duct 6 with described air outlet 2, and described blower unit 5 is connected by ventilation duct 7 with described air outlet 3.
This device also comprises for by 4 supports 8 overhead of described air-supply arrangement, and described support 8 is arranged on described isolation tent 1, described air-supply arrangement 4 times.
The height of described support 8 is 500mm.
Between described air-supply arrangement 4 and described blower unit 5, distance is more than or equal to 1000mm.
The concrete using method of a kind of cable work well detection system exhaust ventilation device that the utility model provides is as follows:
To isolate tent and send into work well inside, and open air-supply arrangement and blower unit, by after the gas displacement out of work down-hole section, the workman goes into the well the isolation tent is installed, and starts working; After end-of-job, the workman will isolate tent and tidy up rear upper well, close air-supply arrangement and blower unit, end operation.
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.
