Abstract
The utility model relates to a kind of instrument, particularly a kind of instrument of charged for replacement smoke sensing device.Be made up of card column, plane seat, expansion link and card column groove, it is characterized in that: plane seat has angle become three card column grooves of 120 degree, three card columns are vertically fixed on the top of three card column groove inner plane seats respectively, and card column can change position in card column groove, expansion link is vertically fixed on the below of plane seat.Owing to adopting technique scheme, the advantage that the utility model has and good effect are: structure is simple, easy to use.
Description
Technical field
The utility model relates to a kind of instrument, particularly a kind of instrument of charged for replacement smoke sensing device.
Background technology
At present, the heart that transformer station runs as power supply enterprise, once breaking out of fire accident, its consequence is by hardly imaginable, and the fire protection alarm system of unattended substation is the important system guaranteeing that substation safety runs.And as the terminal device smoke sensing device of fire alarm system, once break down as do not changed in time, can not sense electrical equipment fire occur before sign, operations staff just by fire incident elimination in bud, thus can not expand accident.Smoke sensing device due to transformer station is installed in the top of charging equipment, and after breaking down, not only replacing construction is long, and brings unsafe hidden danger to staff.
Summary of the invention
Technical problem to be solved in the utility model is: the instrument providing a kind of charged for replacement smoke sensing device, can make staff stand on ground, as long as expansion link is stretched out suitable length, just can change smoke sensing device.The utility model solves the technical scheme that its technical problem adopts: the utility model is made up of card column, plane seat, expansion link and card column groove, it is characterized in that: plane seat has angle become three card column grooves of 120 degree, three card columns are vertically fixed on the top of three card column groove inner plane seats respectively, and card column can change position in card column groove, expansion link is vertically fixed on the below of plane seat.Plane seat and expansion link insulating materials manufacture.
Owing to adopting technique scheme, the advantage that the utility model has and good effect are: structure is simple, easy to use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Figure of description 1 is structural representation of the present utility model.
1. card column 2. plane seat 3. expansion link 4. card column grooves in figure.
Detailed description of the invention
In Figure of description, plane seat (2) there is angle become three card column grooves (4) of 120 degree, three card columns (1) are vertically fixed on the top of three card column grooves (4) inner plane seat (2) respectively, and card column (1) can change position in card column groove (4), expansion link (3) is vertically fixed on the below of plane seat (2).
Operation principle of the present utility model is: when using the utility model, the radius of three the interior card column of card column grooves (4) (1) is regulated according to the inductor of different model, expansion link (3) is stretched out suitable length, three card columns (1) are made to insert in smoke sensing device shell, rotate expansion link (3), just can change smoke sensing device easily.
Claims (1)
