Description
Technical field
The utility model relates to mining equipment technical field, specifically, particularly relates to a kind of methane detection alarming instrument housing.
Background technology
Methane detection alarming instrument is a kind of equipment detecting methane concentration, is mainly used for mine and other can produce the place of methane.This inflammable and explosive gas of methane certainly leads in all process of coal mining, inevitable, once methane concentration exceeds standard very easily accidents caused, very large hazard to person is produced to the workman worked in mine, due to the gas that methane is a kind of colorless and odorless, so just can only be detected by sensitive reliable detecting instrument, therefore the safety in utilization of methane detection alarming instrument is quite important.
Existing methane detection alarming instrument housing is closed housing, and heat dispersion is poor, does not have cover plate outside battery, and battery easily makes moist.
Summary of the invention
In order to solve the problem, the utility model provides a kind of methane detection alarming instrument housing, and housing side is provided with heat dissipation channel can form convection current, and left by heat in time, housing is also furnished with cover plate, prevents battery from making moist.
The utility model is achieved through the following technical solutions:
A kind of methane detection alarming instrument housing, comprise the outer cover body be made up of upper casing 1 and lower casing 2, described outer cover body upper end is provided with valve 6, described upper casing 1 surface is provided with display 3 and operation interface 4, described outer cover body side is provided with heat dissipation channel, described heat dissipation channel comprises some flabellums 7, and described lower casing 2 is also provided with cover plate 5.
Described upper casing 1 and lower casing 2 are described outer cover body by cross recessed countersunk head sscrew 8 split that interfixes.
Described outer cover body is provided with fixed orifice 9, and described flabellum 7 two ends are provided with stationary shaft 10, and described stationary shaft 10 is rotatably fixed in described fixed orifice 9.
Compared with prior art, the beneficial effects of the utility model are:
The utility model structure is simple, novel, and the side of housing is provided with heat dissipation channel, can form the heat that cross-ventilation leaves in housing in time; Heat dissipation channel is made up of some flabellums, flabellum is rotatably fixed on outer cover body side, when needs dispel the heat, flabellum is inclined, the heat dissipation channel of both sides can form cross-ventilation, and during without the need to dispelling the heat, flabellum turns to vertical state and forms lid, closure casing body, prevents the foreign material such as steam grieshoch from entering; Enclosure body is also provided with cover plate, battery can be protected to prevent from making moist.
Accompanying drawing explanation
Fig. 1 is Facad structure schematic diagram of the present utility model;
Fig. 2 is the rear view of the utility model Fig. 1;
Fig. 3 is side structure schematic diagram of the present utility model;
Fig. 4 is the details enlarged drawing at the utility model Fig. 3 A place.
In Fig. 1: 1, upper casing; 2, lower casing; 3, display; 4, operation interface; 5, cover plate; 6, valve; 7, flabellum; 8, cross recessed countersunk head sscrew; 9, fixed orifice; 10, stationary shaft.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
A kind of methane detection alarming instrument housing, comprise the outer cover body be made up of upper casing 1 and lower casing 2, described outer cover body upper end is provided with valve 6, described upper casing 1 surface is provided with display 3 and operation interface 4, described outer cover body side is provided with heat dissipation channel, described heat dissipation channel comprises some flabellums 7, and described lower casing 2 is also provided with cover plate 5.
Described upper casing 1 and lower casing 2 are described outer cover body by cross recessed countersunk head sscrew 8 split that interfixes.
Described outer cover body is provided with fixed orifice 9, and described flabellum 7 two ends are provided with stationary shaft 10, and described stationary shaft 10 is rotatably fixed in described fixed orifice 9.
As depicted in figs. 1 and 2, a kind of methane detection alarming instrument housing, comprise the outer cover body of upper casing 1 and lower casing 2 composition, upper casing 1 and lower casing 2 are described outer cover body by cross recessed countersunk head sscrew 8 split that interfixes, outer cover body upper end is provided with valve 6, upper casing 1 surface is provided with display 3 and operation interface 4, and lower casing 2 is also provided with cover plate 5; As shown in Figure 3, outer cover body side is provided with heat dissipation channel, and described heat dissipation channel comprises some flabellums 7, and outer cover body side is provided with fixed orifice 9, and flabellum 7 two ends are provided with stationary shaft 10, and stationary shaft 10 is rotatably fixed in fixed orifice 9.When methane detection alarming instrument starts, flabellum 7 turns to skewed, and the heat dissipation channel of two sides forms cross-ventilation, and leave heat in time; When methane detection alarming instrument does not work, flabellum 7 turns to vertical position and forms lid, can closure casing body, prevents the foreign material such as steam grieshoch from entering; Lower casing 2 is also provided with cover plate 5, and battery can be protected to prevent from making moist.
The utility model structure is simple, novel, and the side of housing is provided with heat dissipation channel, can form the heat that cross-ventilation leaves in housing in time; Heat dissipation channel is made up of some flabellums, flabellum is rotatably fixed on outer cover body side, when needs dispel the heat, flabellum is inclined, the heat dissipation channel of both sides can form cross-ventilation, and during without the need to dispelling the heat, flabellum turns to vertical state and forms lid, closure casing body, prevents the foreign material such as steam grieshoch from entering; Enclosure body is also provided with cover plate, battery can be protected to prevent from making moist.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
