The magnetic fixing device can be rapidly assembled and disassembled, the workload for assembling and disassembling the firework is reduced, and unsafe factors in the assembly and disassembly process of the firework are reduced.
Description
Technical field
The utility model relates to Cold State Aerodynamic Field Test device, relates in particular to cold smoke flower magnetic force fixed device in a kind of boiler furnace.
Background technology
In " fireworks tracer test " in Cold State Aerodynamic Field Test, by place cold smoke flower at burner nozzle, light simultaneously, by fireworks track, observe pulverized coal flow and enter the trend after burner hearth, cold smoke is spent and must be fixed in advance, and conventional fixing means is to be manually welded and fixed support on burner before adopting test at present, then fireworks is installed in to the mode on support, in addition, adopt in addition artificial colligation fireworks in the mode of the interim shelf pipe of burner nozzle.But, the mode that is manually welded and fixed support needs interim processing fixed support, need be before test the long period be about to begin and be fixed the welding job of support, test complete, also need to spend the long period to remove interim fixed support, the fixed support of an engineering use does not often take next engineering to and uses, and the more material that both consumed by this way, has also spent the longer time.And artificial colligation fireworks make the easy deflection of fireworks angle in the mode of the interim shelf pipe of burner nozzle, affect result of the test; And process of binding also quite wastes time and energy, because staff works on the shelf pipe in burner hearth, increased the unsafe factor in the course of work.
Summary of the invention
Shortcoming for prior art, the purpose of this utility model is to provide cold smoke flower magnetic force fixed device in a kind of boiler furnace, solved that the cold smoke flower that " the fireworks tracer test " in Cold State Aerodynamic Field Test use is wasted time and energy in installing fixation procedure, unsafe problem.
To achieve these goals, the technical solution of the utility model is: cold smoke flower magnetic force fixed device in a kind of boiler furnace, it comprises that one for being adsorbed on magnetic fixing and the clip of spending for clamping cold smoke in boiler furnace, connects by a support between described magnetic fixing and clip.
Preferably, described magnetic fixing comprises a magnetic conduction casing, copper coin is set in described magnetic conduction casing take and separate as two halves, the suction base of the bottom side of described magnetic conduction casing for being made by soft magnetic materials, this suction base place plane and described copper coin place plane are perpendicular, one rotatable magnet is set in described magnetic conduction casing, and described magnet is connected with the turning handle being arranged on outside magnetic conduction casing.
Preferably, described clip comprises two thin alloy-steel sheets, be provided with at an upper portion thereof jockey, in its underpart, be provided with winding device, thin alloy-steel sheet above described winding device is arc-shaped convex, forms a space of taking in cold smoke flower, and the diameter of arc-shaped convex is spent smaller than cold smoke, by winding device, tighten up the thin alloy-steel sheet of described arc-shaped convex, by jockey, be connected with described support.
Preferably, described jockey comprises that two compressing tablets and two screw bolt, utilizes compressing tablet and screw bolt thin alloy-steel sheet and described support are connected into an integral body.
Preferably, in the centre on described two thin alloy-steel sheet tops, be provided with a groove, the position that is adjacent between described two thin alloy-steel sheets takes to be welded to connect.
Compared with prior art, the utility model adopts the magnetic force fixed device of fast mounting-dismounting, reduces the workload of mounting or dismounting fireworks, has reduced the unsafe factor of mounting or dismounting fireworks.

Fig. 2 is magnetic fixing structural representation of the present utility model (attracting state).
Fig. 3 is magnetic fixing structural representation of the present utility model (relieving state).
Fig. 4 is application state schematic diagram of the present utility model.
The specific embodiment
Refer to Fig. 1, Fig. 2 and Fig. 3, in the boiler furnace of the present embodiment, cold smoke flower magnetic force fixed device comprises that one spends 4 clip 2 for the magnetic fixing 1 and being adsorbed in boiler furnace for clamping cold smoke.Magnetic fixing is the device that a dependence magnetic force produces larger absorption affinity, its base 3 can be fixed on to absorption plane (as the upper horizontal plane of burner surrounding steel plate) above or base is taken off from absorption plane, can bear compared with the gentle vertical tension of flood.Magnetic fixing is rectangle, shell 5 is two magnetic conductors, with non-magnetic copper coin 6, separates, and inside is a cylindrical cavity 7, place permanent magnet 8(or the permanent magnetic magnet of a rotatable bar shaped), this permanent magnet or permanent magnetic magnet are N, the S utmost point along diametric(al).The position, bottom side of magnetic fixing is a soft magnetic materials (soft magnetic materials refers under weak magnetic field, a kind of Ferrite Material that easy magnetization also easily demagnetizes).By the outer turning handle being connected with magnet of housing, rotate the magnet of the inside.When the two poles of the earth of magnet (N or S) are above-below direction, when namely the N of magnet or the S utmost point are over against soft magnetic materials base, form the magnetic line of force closed, be just magnetized, in this direction, there is strong magnetic, so can be used in, hold steel surface.And when the two poles of the earth of magnet are during in horizontal direction, and (middle of strip magnet only has minimum magnetic during over against soft magnetic materials base in the middle of NS, can disregard), the magnetic line of force is disconnected by copper coin, soft magnetic materials base can not be magnetized, so now almost there is no magnetic force on base, just can take off from the surface of iron and steel 9 at an easy rate.
Clip is connected for fireworks and holder, by bottom winding device, fireworks is stepped up and adjusts clip and support 10, fireworks firmly can be fixed on to the center of burner nozzle.Clip is high and be comprised of the jockey on the thin alloy-steel sheet of certain toughness, thin alloy-steel sheet top and the winding device of thin alloy-steel sheet bottom by two intensity.Upper connecting connection parts screws bolt by two compressing tablets and two thin alloy-steel sheet and support is fixed into an integral body; In the middle of alloy-steel sheet top, be provided with a groove, make whole clip can regulate upper and lower position, centre is adjacent to position and takes to be welded, bottom dress fireworks two circular arc steel discs more smaller than fireworks diameter, be inserted in the diameter of turning two circular arc steel discs after fireworks by bottom winding device down, utilize the folder power of circular arc steel disc to clamp fireworks, utilize steel disc and fireworks contact area large, the feature that frictional force is large, avoids fireworks radially movable under a wind is moving.The cold smoke flower of test use is generally cylindrical.
Refer to Fig. 4, the utility model is arranged on coal burner 11, can conveniently install and remove, so can reclaim fast, for different engineerings, fixture is recycled, and has saved material consumption.
Although the utility model discloses as above with preferred embodiment, the scope of not implementing in order to limit the utility model.The ordinary person of any this area, within not departing from the scope of utility model, does some improvement, and every equal improvement of doing according to the utility model, should be scope of the present utility model and contain.
