Specific embodiment
Further describe technical scheme below in conjunction with the accompanying drawings, but claimed scope is not limited to institute
State.
As shown in figure 1, a kind of winding connected vessels type inclinometer of the present invention, including skeleton 1, in the middle of described skeleton 1
Part is set to kidney-shaped hollow out 2, is located at and is further opened with cannelure 5 outside hollow out 2, be provided with described cannelure 5 on skeleton 1
Contain the winding linker 6 of liquid 8, described skeleton 1 side is provided with handle 3, and opposite side is provided with I shape measurement plane 4,
Measurement plane 4 adopts I-shape construction one side bending resistance shear resistance strong, good stability, is on the other hand conducive to the present invention to extend
Fast Installation during range is fixed, and described winding linker 6 side is provided with steel ruler 9, and the scale of steel ruler 9 be divided into symmetrical above and below
Two parts, described steel ruler 9 is additionally provided with active cursor 11, described active cursor 11 is provided with aiming pointer 12.Logical
Cross active cursor 11 to support the use to survey reading data with steel ruler 9., up to 0.1mm, described aiming pointer is carefully straight and stable, very for precision
Difficulty occurs bending and deformation.Original state aims at pointer 12 position and is in steel ruler 9 middle, and initial reading is Lmm, and wherein, L is permissible
Produce corresponding range according to different demands, but be to ensure that certainty of measurement with vernier after supporting for the steel ruler is constant, will
On vernier the length of every 1cm with 1mm differed between 1cm length on steel ruler achieve that certainty of measurement is 0.1mm.Described liquid 8
There is good mobility, cold and hot stability and nontoxic non-corrosiveness.This liquid can using transformer oil, hydraulic oil etc. thoroughly
Bright, not volatile, good fluidity, the not-easy-to-freeze liquid being not easy to evaporate, should not be using the cold and hot stability such as water, ethanol difference
Liquid.When using it is stipulated that steel ruler 9 is its positive direction straight down.
Described winding linker 6 is fixed in cannelure 5 by being arranged at the buckle 7 at two ends.
Described winding linker 6 upper end has hole 13, and the effect of hole 13 is toward gas in transfusion in pipe and discharge pipe, and
Hole 13 is closed by rubber stopper 14.
The two ends of described steel ruler 9 are fixed on skeleton 1 by screw 10.
Described cannelure 5 is combined into kidney-shaped structure by straightway and two ends arc section.The shape of described winding linker 6
Mating shapes with cannelure 5.
Described skeleton 1 is rectangular structure, and its length is respectively 250mm, 200mm, 20mm, and four sides are
Vertical.
The left and right sides (i.e. long straight flange side) of described skeleton 1 all has one to handle 3, grips instrument for operator.Described handle 3
Size be 80mm × 40mm × 20mm (length × width × height), inner face makes cambered surface, in order to grip.Described winding linker 6
For transparent glass tube, here necessarily it should be noted that the interior diameter of pipe is unsuitable excessive, the spy of surface tension of liquid otherwise cannot be utilized
Point, the interior diameter of pipe is made 5mm, the length of straigh line 100mm of winding linker 6, the outer radius of the arc section at two ends by here
For 60mm, inside radius 55mm, it is fixed in reserved cannelure 5 on skeleton 1, two ends are fixing with buckle 7, buckle 7 is to mould
Expect the annulus with opening made, and annulus inner ring diameter is matched with the pipe diameter of winding linker 6, will be with activity trip
On the hanger 15 at two ends that the steel ruler of mark 11 is fixed on the vertical central shaft of skeleton, hanger is the square or semicircle of trough of belt, lives
Between aiming pointer 12 on dynamic vernier 11 and pipe face should not excessively pine also unsuitable tension it is ensured that its in linker tube outer surface freely
Slide, in order to avoid impact certainty of measurement.
Before measurement, lower end of the present invention is placed on horizontal plane, during the aiming pointer 12 on active cursor 11 is returned, i.e. pointer
It is in the position of Lmm, opens rubber stopper 14, injection liquid 8 is until liquid level is just at aiming pointer 12 into winding linker 6
Stop liquid feeding body during position, then rubber stopper 14 is filled in hole 13, closed.
The present invention makes full use of law of connected vessels and surface tension of liquid feature, that is,：
(1) in linker liquid constancy of volume.
(2) the intraluminal fluid face of linker both sides is in same level all the time；
(3) liquid surface there is tension force so that in linker pipe water surface curve radial parallel with pipe all the time.
According to above-mentioned 3 principles, in conjunction with Fig. 2 and Fig. 3, the computing formula at inclination angle is carried out with derivation as follows：
Constancy of volume from liquid in linker：
2π(R2-R1)2H1=π (R2-R1)2(H2+H3)
Thus obtaining：
2H1=H2+H3
All the time it is in same level from both sides intraluminal fluid face and liquid has tension force：
So inclination angle theta calculating formula is：
In above formula：
H1For initial liquid level (communicating pipe vertically places, and left and right pipe liquid level is equal)；
H2Left pipe liquid level for winding linker after tilting；
H3Right pipe liquid level for winding linker after tilting；
R1Inside radius for winding linker circular arc portion；
R2Outer radius for winding linker circular arc portion.
Further illustrate the application of the present invention with reference to embodiment.
As shown in Figures 2 to 4, when measuring the inclination angle of vertical, by the I-shaped perpendicular measurement plane 4 of the present invention against quilt
The surface of geodesic structure thing 15, after 6 liang of intraluminal fluid positions of winding linker are steady, mobile active cursor 11, when aim at pointer 12 with
When the intraluminal fluid face of close steel ruler 9 side just overlaps, read the reading of steel ruler 9 and the reading of active cursor 11, the two
It is added as current level H2, thus can calculate corresponding inclination angle.Thus drawing the surfaces slope of tested works 15.When
During the irregularity degree of measurement horizontal plane, the regulating step before measurement ibid, now only needs to be placed directly in the present invention tested
On face, equally after in 6 liang of pipes of winding linker, water level is steady, mobile active cursor 11, when aiming pointer 12 and close steel ruler 9
When the water surface just overlaps in the pipe of side, read the reading of steel ruler 9 and the reading of active cursor 11, the two is added as works as
Front water level H2, thus can calculate corresponding irregularity degree.
The certainty of measurement of the present invention and resolution mainly to be determined by liquid level difference, the liquid level difference measuring twice is bigger,
More obvious, prior art means are more easily differentiated, and its availability is higher.The part of the present embodiment listed from table 1 calculates
Result is not difficult to find out, corresponding to vernier steel ruler minimum precision 0.1mm when, the present invention minimum angle measurement be 0.0955 °, show angle measurement
Precision and resolution are very high.Institute's measuring angle increases with liquid level difference and increases, and shows that measurable angle range is larger.Can from the inclination angle calculating
To judge the direction (on the occasion of showing that, inside tendency, negative value shows outside tendency) tilting, therefore very useful.The present invention operates
Convenient, Computing Principle is simple, the low manufacture cost of instrument, and is easy to maintaining it is easy to carry, and the scope of application is very wide.
