Abstract
The utility model relates to a kind of multi-functional confined space ventilation wind system, comprise top cover, fan main body and air-supply arrangement, fan main body is the cylinder barrel shaped structure vertically arranged, a top cover is coaxially fixed with in fan main body upper end, coaxially be shaped with a blower fan preformed hole in the middle part of top cover, on the top cover of this blower fan preformed hole periphery, radial equipartition is hinged with multiple exhaust door; Be sealed and installed with an air-supply arrangement in fan main body lower end, air-supply arrangement passes to work bottom.The utility model underground work well exhaust ventilation system, in conjunction with work well feature, produces exhaust ventilation system targetedly, solves the problem that construction is sluggish in air circulation in work well, and when effectively avoiding operation in work well, poisonous gas causes infringement to workmen.
Description
Technical field
The utility model belongs to power engineering, relates to the confined space operations such as the interior construction of underground work well, especially a kind of multi-functional confined space ventilation wind system.
Background technology
Power engineering, especially cable work construction often need to fulfil assignment in the work well of underground.Construct for a long time in limited space, have high risks to workmen's health, and there is huge hidden danger.In order to reduce hidden danger, harm reduction, need solve the exhaust ventilation problem of the underground confined space.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of design science, rational in infrastructure, easy to use, economical and practical multi-functional confined space ventilation wind system.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of multi-functional confined space ventilation wind system, it is characterized in that: comprise top cover, fan main body and air-supply arrangement, fan main body is the cylinder barrel shaped structure vertically arranged, a top cover is coaxially fixed with in fan main body upper end, coaxially be shaped with a blower fan preformed hole in the middle part of top cover, on the top cover of this blower fan preformed hole periphery, radial equipartition is hinged with multiple exhaust door; Be sealed and installed with an air-supply arrangement in fan main body lower end, air-supply arrangement passes to work bottom.
And air-supply arrangement adopts stuffy cloth to make, air-supply arrangement top establishes sealing buckle to be fixedly connected on fan main body lower end.
And exhaust door airtight lock is on top cover, and exhaust door is selected to open according to construction environment.
Advantage of the present utility model and good effect are:
The utility model underground work well exhaust ventilation system, in conjunction with work well feature, produces exhaust ventilation system targetedly, solves the problem that construction is sluggish in air circulation in work well, and when effectively avoiding operation in work well, poisonous gas causes infringement to workmen.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the upward view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of multi-functional confined space ventilation wind system, comprise top cover 1, fan main body 4 and air-supply arrangement 6, fan main body is the cylinder barrel shaped structure vertically arranged, a top cover is coaxially fixed with in fan main body upper end, this cap structure is see accompanying drawing 1, and be coaxially shaped with one in the middle part of top cover for installing the blower fan preformed hole 3 of blower fan, on the top cover of this blower fan preformed hole periphery, radial equipartition is hinged with multiple exhaust door 2, exhaust door is salable to be locked on top cover, and exhaust door is selected to open according to construction environment;
An air-supply arrangement 6 is sealed and installed with in fan main body lower end, air-supply arrangement passes to work bottom, because the most toxic gas density ratio air qualities in work well are large, so need the air-out of blower fan to deliver to work bottom (if having water in well, then need to deliver to the water surface), effectively could discharge toxic gases such as carbon dioxide.The air-supply arrangement of the present embodiment adopts stuffy cloth to make, and both sides establish folding device to be convenient to preserve, and air-supply arrangement top establishes sealing buckle 5 to be fixedly connected on fan main body lower end.
When exhaust system is applied to single pithead work well, open exhaust door, solve the problem that single well head installs blower fan air draft nowhere; When exhaust system is applied to double-wellhead work well, a well head can be installed blower fan and locked exhaust door, another well head is used for air draft, effectively can strengthen work well inner air flow like this.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
