Abstract

Disclosed in the utility model is an electric meter box comprising a box body and a box cover. A device accommodation cavity for accommodating electric meters is formed by buckling of the box body and the box cover; a fire extinguishing capsule for peripherally encircling the meters and a control switch is arranged in the device accommodation cavity; an object placing opening and wiring holes for passing of connecting wires of the meters are formed in the fire extinguishing capsule; and the space inside the fire extinguishing capsule is filled with a dry type fire extinguishing medium, wherein the fire extinguishing capsule is made of an inflammable material. Because of the dry type fire extinguishing medium, fire extinguishing can be carried out effectively; and the box body, the box cover and elements in the device accommodation cavity can be protected from being polluted, and easy cleaning can be realized. Under the circumstances that the meters and the control switch are encircled by the fire extinguishing capsule, when the meters or the control switch catch fire due to the short circuit; and the flame spreads, and the fire extinguishing capsule burns and is damaged easily because of the used inflammable material. Therefore, the dry type fire extinguishing medium inside the fire extinguishing capsule flows outwardly and then splashes, so that the flame is extinguished.

By adopting technique scheme, fire extinguishing capsule arranges placing port and is convenient for people to pour dry type firing-fighting medium in fire extinguishing capsule, and when wiring hole being set conveniently surrounding ammeter or gauge tap, wiring passes through; Adopt dry type firing-fighting medium effectively to put out a fire, moreover can not pollute the components and parts in casing, case lid and device cavity volume after fire extinguishing, easily cleaning; Fire extinguishing capsule surrounds ammeter and gauge tap, like this when ammeter or gauge tap are caught fire because of short circuit, propagation of flame meeting burns fire extinguishing capsule, fire extinguishing capsule is that inflammable material forms, can be easy to burn and break, thereby flow out the dry type firing-fighting medium in it, thereby dry type firing-fighting medium can splash out and knocks out flame after exposing.

Further improvement as technique scheme: described fire extinguishing capsule is the setting of frame type, the hollow part of this framework is for placing the parcel of ammeter, the other end that described fire extinguishing capsule is provided with wiring hole is fixedly connected with lanyard, and described casing correspondence is provided with for tangling the keeper of lanyard.

Described electronic box body top is fixedly connected with media storage chamber, and described media storage chamber is provided with charging aperture and discharging opening, and described placing port and lanyard are located at the same side of fire extinguishing capsule, and described discharging opening is connected with placing port UNICOM.

Described dry type firing-fighting medium is dry powder or sand.

Described inflammable material is plastic foil.

By adopting technique scheme, the good and components and parts of can not making dirty of the firing-fighting medium extinguishing property of dry type, arrange media storage chamber and provide abundant dry type firing-fighting medium fire extinguishing, reasonable in design for fire extinguishing capsule.

Embodiment

Referring to figs. 1 through Fig. 2, the utility model ammeter box embodiment is described further.

A kind of ammeter box, comprise casing 1 and case lid, described casing 1 and case lid are buckled into the device cavity volume for accommodating ammeter 2, in described device cavity volume, be provided with for circumferentially surrounding the fire extinguishing capsule 3 of ammeter 2 and gauge tap, the wiring hole 32 that described fire extinguishing capsule 3 is provided with placing port 34 and passes for the wiring of ammeter 2, in this fire extinguishing capsule 3, be filled with dry type firing-fighting medium, described fire extinguishing capsule 3 consists of inflammable material; Described dry type firing-fighting medium is dry powder or sand; Described inflammable material is plastic foil.

By adopting technique scheme, fire extinguishing capsule 3 arranges placing port 34 and is convenient for people to pour dry type firing-fighting medium in fire extinguishing capsule 3, and when wiring hole 32 being set conveniently surrounding ammeter 2 or gauge tap, wiring passes through; Adopt dry type firing-fighting medium effectively to put out a fire, moreover can not pollute the components and parts in casing 1, case lid and device cavity volume after fire extinguishing, easily cleaning; Fire extinguishing capsule 3 surrounds ammeter 2 and gauge tap, like this when ammeter 2 or gauge tap are caught fire because of short circuit, propagation of flame meeting burns fire extinguishing capsule 3, fire extinguishing capsule 3 is that inflammable material forms, can be easy to burn and break, thereby flow out the dry type firing-fighting medium in it, thereby dry type firing-fighting medium can splash out and knocks out flame after exposing; Dry powder or sand fire extinguishing are mainly the contacts for isolated air and comburant, thus effectively fire extinguishing; More common and the less expensive of sand, the relative sand of dry powder price is higher, so herein preferably sand as dry type firing-fighting medium, certainly also sand can be replaced with to pure sand as dry type firing-fighting medium; Fire extinguishing capsule 3 adopts plastic foil to make, and the fire extinguishing capsule 3 that loads dry type firing-fighting medium is easily broken, once fire extinguishing capsule 3 is burnt, breaks, and dry type firing-fighting medium is gone out immediately fire extinguishing capsule 3 and stamped out the flames.
