Description
Technical field:
The utility model relates to a kind of dust cover, especially relates to a kind of dust cover of outdoor electric equipment box body.
Background technology:
Outdoor electric equipment box body is cable interface by the below of casing and extraneous electrical link, cable has carried out encapsulation process by fireproof blocking layer to electrical equipment box body when entering electrical equipment box body, simultaneously for dust-proof consideration, electric component box doorjamb has sealing ring usually, makes the environment that electrical equipment box body inside formation one is closed.Electrical equipment box body is often connected with the cable trough of underground, the ambient humidity of underground cable ditch is larger than ground environment, out of doors in running environment, particularly in the northern season in spring and autumn that day and night temperature is larger, the moisture entering electrical equipment box body easily causes condensation or hangs white phenomenon, cause electric insulation to decline, significantly increase the security risk of electric equipment.For addressing this problem, the electrical equipment box body of environment out of doors can arrange air vent hole, being communicated with external world's appropriateness, discharging inner moisture by air vent hole, to prevent condensation or to hang white formation.Especially the sky air exhaustion such as strong wind, airborne dust, rain, snow is unfavorable for the dust-proof of the electrical equipment box body with air vent hole and insulation, further increases the security risk of staff.
Utility model content:
The technical problems to be solved in the utility model is the shortcoming overcoming prior art, provides a kind of dust cover of outdoor electric equipment box body ventilating opening, with solve electrical equipment box body add air vent hole after the problem of dust-proof weak effect.
The utility model is implemented by following technical scheme: a kind of dust cover of outdoor electric equipment box body ventilating opening, and it comprises protective cover, protective cover gasket seal, capping, posting and dust cap; Described protective cover comprises the Qian shape main body that Open Side Down, is provided with baffle plate in described Qian shape main body one side end face, has four screw rods described Qian shape main body opposite side end face is evenly distributed; Described protective cover is fixed on outside the air vent hole of described electrical equipment box body by described screw rod grafting, and described screw tip is through described electrical equipment box body, and it is inner to be placed in described electrical equipment box body; The described protective cover gasket seal corresponding with described protective cover back side shape is provided with between described electrical equipment box body with described protective cover; Described capping comprises capping base plate, and described capping base plate is densely covered with aperture; Be welded with metallic elastic jump ring in described capping base plate both sides, described capping is connected on the inwall at described Qian shape body openings place by described metallic elastic jump ring active card; Described posting is arranged on the described screw rod of described electrical equipment box body interior; In the middle of the plastic plate of described dust cap, have the otch with described vent size position consistency, embedded magnet sheet on the described plastic plate of described otch surrounding, described dust cap is connected on described posting by described flat thin magnet magnetic-adsorption.
Described protective cover gasket seal adopts rubber to make.
Described dust cap is made up of two-layer described plastic plate and the sponge interlayer between it.
Advantage of the present utility model: the capping being installed at protective cover end opening can strengthen dust-proof effect, and the subenvironment formed with the inner space of protective cover carries out first order filtration to dust.Dust cap is connected by flat thin magnet magnetic-adsorption with iron plate posting, makes the mounting or dismounting of dust cap become very convenient.If desired carry out lead-in wire operation, capping and dust cap can be removed, carry out lead-in wire operation by dust cover opening and air vent hole.
Accompanying drawing illustrates:
