Description
Technical field
The present invention relates to a kind of fireproof covering, more particularly to a kind of fireproof covering of vibrating sensor.
Background technology
Vibration measuring point in the experiment of engine high mould, fire trial are located at the vibration measuring point near engine afterbody, between level
Vibration measuring point during separation test near first class engine afterbody and in two level enging cabin, is all easily arrived by baked wheaten cake, is caused
Make that test data is imperfect or reliability is low, it is necessary to carry out flameproof protection；Measuring point in stage separation test two level enging cabin, by
In influence docking need first by sensor with test cable connect, and in cabin narrow space, it is necessary to after first flameproof protection again on
Stage body enters line sensor stickup.
Existing vibrating sensor flameproof protection method is to use fire prevention alkali-free cloth along sensor and its cable joint outer layer
Layer winding, until sensor, sensor and cable connection are all surrounded by alkali-free cloth.Existing sensor fire prevention wrapping method exists
Sensor is easily set to be loosened with test cable connection in winding process；During stage separation test, sensor and test cable must
It must in advance link together, and be wound and protected with alkali-free cloth, sensor taping process, test cable fixation procedure, cable and nothing
Phase mutual friction between alkali cloth, easily make sensor with being loosened at test cable connection, alkali-free cloth winding.
The content of the invention
The technical problem to be solved in the present invention is a kind of fireproof covering of vibrating sensor, is not limited with solving to realize by space
The problem of making and not influenceing the flameproof protection of sensor and the vibrating sensor of cable connector connection status.
For technical problem existing for solution, the technical solution adopted by the present invention is：A kind of fireproof covering of vibrating sensor, bag
Include body, running-on and set bottom, described body is folded in half into bilayer by the square alkali-free cloth of a block length along two long sides, by rectangle without
The flanging and its opposite side that alkali cloth doubling obtains are fixed together, and make bottomless, uncovered a cylindrical shape, and fixed part uses
Fire-proof belt is pasted one week, to strengthen the flameproof effect of the part of gluing mistake；The cylinder that described set opening's edge body is made
Upper brim edge is abreast folded down inside cylinder, and the edge portions suitable for reading of folding and cylinder inwall is closely solid
It is fixed, cylinder upper brim is penetrated a root long degree in pipeline more than cylinder girth suitable for reading, quality along a circular pipe is formed
Soft wiring, by pulling wiring to control the size of running-on；Described set bottom is consistent with the way of running-on, and carries out vibration biography
During sensor flameproof protection, the wiring at control set bottom will be according to the vibrating sensor and mass being fixed on solid propellant rocket
Volume size is shunk, and vibrating sensor and its mass is in the alkali-free cloth protection of opposing seal, no
Can shrink tightly influences very much the connection status of vibrating sensor and cable connector.
Beneficial effect
Vibrating sensor fireproof covering of the present invention tries primarily directed to the high mould experiment of solid propellant rocket, ground experiment etc.
The flameproof protection of vibrating sensor when testing project, disclosure satisfy that the flameproof protection of different measurement direction vibrating sensors, avoid by
Sensor and test cable connection loose phenomenon are caused along sensor, cable winds in flameproof fabric, do not limited by operating space,
Original cable connector connection status, easily and efficiently sensor flameproof protection will not be changed.Shorten the test period, improve experiment
Reliability.
Brief description of the drawings：
Fig. 1 is a kind of vibrating sensor fireproof covering profile；
Fig. 2 is that a kind of vibrating sensor fireproof covering deploys plane structure chart along butt joint edge；
In figure：1 is body, and 2 be running-on, and 3 be set bottom, and 4 be butt joint edge, and 5 be wiring, and 6 be vibrating sensor, and 7 be to cut open side.
Embodiment：
The present invention is further elaborated on reference to specific embodiment.
A kind of vibrating sensor fireproof covering of the present invention, including body 1, running-on 2, set bottom 3.
Body 1 is to be folded in half into bilayer along two long sides by the square alkali-free cloth of a block length, and such flameproof effect is more preferable, and body is not
Gap occurs.Flanging that rectangle alkali-free cloth doubling is obtained and its opposite side stretch out 1cm, as butt joint edge 4, with 502
It is glued together, make bottomless, uncovered a cylindrical shape.Then docking rim portion reuses fire-proof belt and pasted one week,
To strengthen the flameproof effect of butt joint edge adhesive portion.
Running-on 2 is that the upper brim edge for the cylinder made along body 1 is abreast folded down 1cm inside cylinder, and
Folded portion is closely pasted along part wide edge 0.5cm and cylinder inwall with 502 glue, makes cylinder upper brim along formation
One circular pipe.A root long degree is penetrated in pipeline more than cylinder girth 1cm suitable for reading, the wiring 5 of soft texture, passes through pulling
Wiring 5 can control the size of running-on 2.When carrying out vibrating sensor flameproof protection, by vibrating sensor and its cable connections
Divide after being all inserted in protective case, the wiring of running-on is tensed until running-on does not have gap, and fixes, as shown in figure 1, making vibration
Sensor and its junction portion are in the alkali-free cloth protection of opposing seal.
It is substantially coincident to cover the way at bottom 3 and running-on 2, the special place of emphasizing is to cover to penetrate a root long degree in bottom 3 more than circle
Mouth girth 2cm wiring under cylinder, when carrying out vibrating sensor flameproof protection, the wiring of control set bottom size will pass according to vibration
The mass volume size of sensor is shunk, and makes mass and its does not have gap, finally to make vibration with engine fixed position
Sensor and its mass will be in the alkali-free cloth protection of opposing seal, and can not shrink too tight influence vibrating sensor with
The connection status of cable connector.
Alkali-free cloth size selection gist of preventing fires is determined according to the size of vibrating sensor 6 and the direction of test to be protected
's.For example, conventional one direction vibrating sensor 6 adds quality block length 4cm, girth 4cm, when making its fireproof covering, running-on makes
1cm is needed, set bottom, which makes, needs 1 cm, and vibrating sensor 6 needs 2cm with cable butted part, and body makes butt joint edge or so
Both sides respectively need 1cm, from alkali-free cloth size are 12 × 8cm for this, along long side doubling after size be changed into 6 × 8cm, be fabricated to circle
The high 6cm of cylinder fireproof covering, the long 5cm of base circumference.
The making of body can be folded in half into bilayer along two long sides by the square alkali-free cloth of a block length, by rectangle alkali-free cloth
Together with the flanging that doubling obtains and its opposite side protective wire linear slit, then with fire-proof belt it will sew bonding partially one week.
When running-on and set bottom make the pipeline of tying line, 502 glue can also be changed to fire prevention silk thread sewing.
The vibrating sensor fireproof covering of the present invention, applied to the high mould experiment of Multiple Type engine, fire trial, level
Between vibrating sensor flameproof protection in separation test, flameproof effect is good, not only shortens experiment time, more improves test data
Reliability.
