The actual pressure is converted to the stop position of pendulum and is shown by the liquid crystal display in 61 outside of outer cover by actual pressure
Come.
In the scene of a fire, due to high temperature, the influence of thick fog etc., it is likely that can not work normally power supply etc., so, according to
The instrument that bad power supply is powered is possible to go wrong；The gyroscope uses mechanical structure, even if after power supply damage, according to
The position of gravity can so be estimated by observing the swing of pendulum, to guarantee that gyroscope insufficiency portion loses, reliably
Property it is high.
Wherein, the axis that the axis and the symmetrical both ends of the interior ring stand 63 that the symmetrical both ends of the outer ring stand 62 are linked to be are linked to be
Line is orthogonal.
Wherein, the axis and the fixing axle 64 that the symmetrical both ends of the interior ring stand 63 are linked to be are orthogonal.
Wherein, the plane where 65 swinging track of pendulum is vertical with the axis of the fixing axle 64, in this way, pendulum 65
Minimum is influenced by fixing axle 64 during swing.
When the pendulum 65 is in the middle position of the guide rail 69, the spring 67 is in nature elongation state, right
The pressure that two pressure sensors 66 between the spring 67 and the pendulum 65 are arranged in is zero.
The outer ring stand is annulus, and outside both ends are symmetrical arranged that there are two protrusions, and the lines of two protrusions are by described outer
The center of circle of ring stand；Circular hole corresponding with two protrusions of the outer ring stand is provided on the outer cover, described in the protrusion insertion
In circular hole, the outer ring stand is rotated around the axis that two circular holes are linked to be.
The interior ring stand is also annulus, outside both ends be symmetrical arranged there are two protrusion, two protrusion lines pass through described in
The center of circle of interior ring stand；Circular hole corresponding with two protrusions of the outer ring stand, the protrusion are provided on the inside of the outer ring stand
It is inserted into the circular hole, the axis that the interior ring stand is linked to be around two circular holes is rotated.
The fixing axle is a straight-bar, and there are two circular holes, the line of the circular hole to pass through described for setting on the inside of the interior ring stand
The center of circle of interior ring stand；The both ends of the straight-bar are inserted into two circular holes of the interior ring stand, so that the fixing axle can be around two
The axis that circular hole is linked to be is rotated.
In this way, pendulum is located at position vertically downward, the outer ring stand, interior ring stand and the fixation in normal place
Axis is remain stationary；After the gyroscope is mobile, the pendulum is no longer at position vertically downward, then under the effect of gravity,
The pendulum can be mobile to the position vertically downward；Since pendulum can only be swung perpendicular to the fixing axle, then
If position vertically downward, not on the motion profile of the pendulum, the pendulum can still be moved to position vertically downward
It is dynamic, it is moved in this way, just will drive and limit the fixing axle of the pendulum motion track；Since the fixing axle is only capable of around described
The axis that two circular holes are linked to be on the inside of interior ring stand is rotated, then the fixing axle will drive the interior ring stand and be moved, directly
Until when the motion profile of the pendulum is moved to by the vertical down position.
It is protrusion in the middle part of the fixing axle, the lobed interior has groove 641, and the groove is columnar hole, axis
It is overlapped with the axis of the fixing axle；Described pendulum one end is T font, and top is horizontal cylinder, and the cylinder is inserted into institute
State in columnar hole, and can the axis in the columnar hole along the columnar hole rotated, in this way, can be to the pendulum
Motion profile is defined, and swings the pendulum around the fixing axle.
The outside of the protrusion is fixed with half circular track 69, and the center of circle of the half circular track is overlapped with the protrusion；
The screen coincident that the motion profile of plane and the pendulum where the half circular track determines, and the half circular track
Arc area passes through the pendulum, so that the motion profile of the pendulum is overlapped with the arc area of the half circular track, this
Sample, the pendulum are swung along the half circular track.
It is arranged on the arc area of the half circular track there are two spring, one end of the spring is separately positioned on described
The both ends of half circular track, the other end of the spring are fixedly connected with the pendulum, in this way, by the half circular track and institute
It states pendulum to connect, when so that the pendulum is static, is located exactly at the midpoint of the half circular track arc area.If (pendulum
When hammering static into shape, the top of the half circular track is simultaneously non-horizontal, and in other words pendulum is not located at the arc area at this time
Midpoint, then the compression situation of two springs is not identical, thus can generate the torsion for rotating the pendulum/half circular track,
Until the upper level of the half circular track, so that pendulum is located at the midpoint of mutual alpha region)
The axis that the fixing axle can be linked to be around two circular holes of the interior ring stand is rotated, so that the semicircle
The axis that guide rail can also be linked to be around two circular holes of the interior ring stand is rotated, and self-position is adjusted.
If gyroscope position is mobile, the one or more in the outer ring stand, interior ring stand and the fixing axle can be
It is rotated under the direct or indirect effect of pendulum, until the pendulum restores position vertically downward again.
In normal place, pendulum is located at position vertically downward, and pendulum is in the middle position of guide rail at this time, and described
Two springs of pendulum connection are in the state of nature elongation, are separately positioned on what two springs were contacted with the pendulum
The pressure signal of two pressure sensors of one end is also 0, represents spring at this time and has no active force to pendulum.
Subject to the axis of fixing axle, to the other end in terms of one end of axis, the swing of the pendulum and axis are orthogonal；
After the Motions of Gyroscope, the position of the pendulum is constant relative to the position of gyroscope, but its absolute position can become
Change, that is to say that the position of pendulum can leave position vertically downward, at this time, under gravity, pendulum can to vertically to
Under position it is mobile, until the position that pendulum restores vertically downward just stops；In the pendulum process mobile to vertical down position
In, due to the limitation of inherent structure, pendulum can only be swung along the direction perpendicular to fixing axle axis, other can make
The movement that pendulum is finally reached vertical down position is completed by the movement of fixing axle etc.；It is led if position vertically downward is located at
The side in rail middle position, for ease of description, we are referred to as on the left of guide rail, and (it is only an address, and reference, which is left, to be led
A kind of side that the middle position of rail is deviated to both ends, if it is desirable, right side etc. can also be referred to as), then pendulum can be in weight
Under the action of power (the real motion profile of pendulum is very complicated, but herein, we only describe its position relative to fixing axle
Set variation) it moves to the left, at this point, the other end, which is separately fixed at, leads since one end of two springs is fixed on the pendulum
Semicircular two ends of rail, therefore the meeting one end for being fixed on the spring on the pendulum left side is fixed, the other end with pendulum movement
It is inwardly compressed, compressed spring can apply elastic force to the right to pendulum, and the pressure sensor connecting with the spring will receive
It squeezes to generate the pressure signal for being greater than 0, meanwhile, it is fixed on spring meeting one end on the right of pendulum and fixes, the other end is with pendulum
Movement stretch out, the spring after stretching can give pendulum to apply elastic force to the right, the pressure sensor connecting with the spring
It will not be squeezed to which its pressure signal remains as 0；At this point, pendulum will receive the elastic force to the right of two springs, the bullet
Power move it is contrary, pendulum under the action of elastic force, can it is gradually slack-off, stop, finally under the effect of elasticity to the right
Movement；In this way, pendulum will receive the double action of gravity and elastic force, wherein gravity and elastic force can be in certain of bob motion track
Reach balance on a bit, in the left side of the balance, elastic force is greater than gravity, and on the right side of the balance, gravity is greater than elastic force, pendulum meeting
The left and right sides in the position since gravity, elastic force and inertia are waved, and is tapered off in the equilibrium position.This is flat
Weighing apparatus might not be exactly at the position of pendulum vertically downward at position, be only that gravity and elastic force reach at the position of balance,
And with the movement of fixing axle, which can constantly change, and finally, can make the vertical of the equilibrium position and pendulum
Down position is overlapped.In the whole process, the main function of spring is the main force for increasing bob motion, so that pendulum can be with
It is static as early as possible get off (can be slowly static due to resistances such as mechanical frictional force when bob motion, but its static time and
The size of the resistances such as the mechanical friction being subject to has much relations, if resistance is excessive, final resting position and reality are hung down
Straight downward position deviation is very big, if resistance is too small, the time for restoring static then can be very long, and if Motions of Gyroscope
Time interval be less than the time for replying static needs, then may pendulum static can not just get off at all), meanwhile, spring is applied
Add active force that can measure by the pressure sensor of addition, so as to analyze its resting position before static, improves
The speed of judgement.
The foregoing is merely presently preferred embodiments of the present invention, is merely illustrative for the purpose of the present invention, and not restrictive
's.Those skilled in the art understand that in the spirit and scope defined by the claims in the present invention many changes can be carried out to it,
It modifies or even equivalent, but falls in protection scope of the present invention.
