Description
Technical field
The utility model relates to a kind of protective cover of fire manual alarm device, in particular, particularly relates to a kind of protective cover of that the salt fog on warning device and sea, daylight, wind and rain can be kept apart, that offshore oilfield uses fire manual alarm device.
Background technology
The fire manual alarm device that offshore production platform or boats and ships use, under being in the rugged surroundings such as salt fog, daylight, wind and rain for a long time, aging speed is fast, and damage frequency is high, needs regular maintenance or replacing.Fire manual alarm device in a shelf-life usual season is once changed or repairs, and within usual one month that exceeds the shelf-life, once changes or repairs, in order to avoid the safety in production that impact is marine.
Although the cost of fire manual alarm device is not very very high; but this repair frequently and change very loaded down with trivial details; if maintenance or replacing are not in time; just in case when running into fire generation; larger security incident may be caused; therefore need a kind of effective protective device badly, reduce the serviceable life of marine exposed fire manual alarm device, guarantee the normal use of warning device.
Summary of the invention
The utility model, in order to overcome the shortcoming of above-mentioned technical matters, provides a kind of protective cover of fire manual alarm device.
The protective cover of fire manual alarm device of the present utility model, the case lid comprising the inner casing for cavity and casing is sealed, a side of described case lid is arranged on casing rotationally by hinge; Its special feature is: the bottom surface of casing offers the wire hole be convenient to alarm cables and passed, fire manual alarm is arranged in the internal cavities of casing; The side of described box opening is provided with annular ridge, the inside surface of case lid is provided with the annular groove matched with annular ridge; The side of box opening is fixed with the first magnet, case lid is fixed with the second magnet matched with the first magnet; Three sides of described case lid and casing are provided with the transparent glass window being convenient to observe box house situation.
The protective cover of fire manual alarm device of the present utility model, the outside surface of described case lid is fixed with the handle being convenient to case lid to open and close.
The protective cover of fire manual alarm device of the present utility model, described casing is cubic shaped.
The beneficial effects of the utility model are: the protective cover of fire manual alarm device of the present utility model, sets out string holes by the bottom at casing, achieve alarming line and are connected with the fire manual alarm device being arranged in casing through wire hole.By coordinating of the annular ridge on casing and the annular groove on case lid, have effectively achieved the sealing to the fire manual alarm device being arranged in box cavity; By the suction-operated of the first magnet and the second magnet, further increase the sealing of casing and case lid.By offering transparent glass window on casing and case lid, being convenient to personnel's all directions from the outside and observing situation in box cavity, being convenient to check it.
Protective cover of the present utility model; fire manual alarm device is arranged in the internal cavities of casing; seal protection has been carried out to it; avoid under it is in the rugged surroundings such as salt fog, daylight, wind and rain for a long time; reduce aging speed fast; extend serviceable life, the physical property of fire manual alarm also can be avoided simultaneously to collide, achieve its effective protective effect.
