Described winding linker 6 is fixed in ring groove 5 by the buckle 7 being arranged at two ends.
Described winding linker 6 upper end has hole 13, and the effect of hole 13 is infused in pipe and gas in vent pipe, and hole 13 is closed by rubber plug 14.
The two ends of described steel ruler 9 are fixed on skeleton 1 by screw 10.
Described ring groove 5 is combined into kidney-shaped structure by straight-line segment and two terminal circle segmental arc.The shape of described winding linker 6 and the mating shapes of ring groove 5.
Described skeleton 1 is rectangular structure, and its length is respectively 250mm, 200mm, 20mm, and four sides are vertical plane.
The left and right sides (i.e. long straight flange side) of described skeleton 1 all has on the other hand 3, grips instrument for operating personnel.Described handle 3 is of a size of 80mm × 40mm × 20mm (long × wide × high), and inner face makes cambered surface, so that grip.Described winding linker 6 is transparent glass tube, here must note, the interior diameter of pipe is unsuitable excessive, otherwise the feature of surface tension of liquid cannot be utilized, at this, interior diameter of pipe is made 5mm, the length of straigh line 100mm of winding linker 6, the external radius of the arc section at two ends is 60mm, inside radius 55mm, be fixed in ring groove 5 reserved on skeleton 1, two ends buckle 7 is fixed, the annulus with opening that buckle 7 is made for plastics, and the pipe diameter of annulus inner ring diameter and winding linker 6 matches, steel ruler with active cursor 11 is fixed on the hanger 15 at the two ends of the vertical central shaft of skeleton, hanger is the square or semicircle of trough of belt, aiming pointer 12 on active cursor 11 and pine also unsuitable tension should not be crossed between pipe face, ensure that it is free to slide at linker tube outer surface, in order to avoid affect measuring accuracy.
Before measurement, the utility model lower end is placed on surface level, during aiming pointer 12 on active cursor 11 is returned, namely pointer is in the position of Lmm, open rubber plug 14, in winding linker 6, inject liquid 8 until liquid level is just in stopping when aiming at pointer 12 position add liquid, then rubber plug 14 is filled in hole 13, close.
The utility model makes full use of law of connected vessels and surface tension of liquid feature, that is:
(1) constancy of volume of liquid in linker.
(2) the intraluminal fluid face of linker both sides is in same level all the time;
(3) liquid surface has tension force, makes to be communicated with radial parallel all the time with pipe of water surface curve in organ pipe.
According to above-mentioned 3 principles, it is as follows that composition graphs 2 and Fig. 3 carry out derivation to the computing formula at inclination angle:
Constancy of volume from liquid in linker:
2π(R
2-R
1)
2H
1＝π(R
2-R
1)
2(H
2+H
3)
Thus obtain:
2H
1＝H
2+H
3
All the time to be in same level from intraluminal fluid face, both sides and liquid has tension force:
So inclination angle theta calculating formula is:
With in above formula:
H
1for initial liquid level (communicating pipe vertically places, and left and right pipe liquid level is equal);
H
2for the left pipe liquid level of winding linker after tilting;
H
3for the right pipe liquid level of winding linker after tilting;
R
1for the inside radius of winding linker circular arc portion;
R
2for the external radius of winding linker circular arc portion.
Application of the present utility model is further illustrated below in conjunction with embodiment.
As shown in Figures 2 to 4, when measuring the inclination angle of vertical plane, by the surface of I-shaped perpendicular measurement plane 4 of the present utility model near tested works 15, after winding linker 6 liang of intraluminal fluid positions are steady, mobile active cursor 11, when aiming pointer 12 just overlaps with the intraluminal fluid face near steel ruler 9 side time, read the reading of steel ruler 9 and the reading of active cursor 11, the two addition is current level H
2, corresponding inclination angle can be calculated thus.Thus draw the surfaces slope of tested works 15.When measuring the irregularity degree of surface level, regulating step before measurement is the same, the utility model is now only needed directly to be positioned on tested surface, equally after water level in 6 liang, winding linker pipe is steady, mobile active cursor 11, when aiming at pointer 12 with time the water surface just overlaps in the pipe of steel ruler 9 side, read the reading of steel ruler 9 and the reading of active cursor 11, the two addition is current level H
2, corresponding irregularity degree can be calculated thus.
Measuring accuracy of the present utility model and resolution mainly decide by liquid level difference, i.e. the liquid level difference of twice measurement more greatly, more obvious, prior art means are more easily differentiated, and its availability is higher.The some numerical results of the present embodiment listed from table 1 is not difficult to find out, during minimum precision 0.1mm corresponding to vernier steel ruler, the minimum angle measurement of the utility model is 0.0955 °, shows that angle measurement accuracy and resolution are very high.Institute's measuring angle increases along with liquid level difference and increases, and shows that measurable angle range is larger.The direction (on the occasion of showing tendency inner side, negative value shows tendency outside) tilted can be judged from the inclination angle calculated, therefore very practical.The utility model is easy to operate, and Computing Principle is simple, and the cost of manufacture of instrument is low, and is convenient to maintaining, is easy to carry about with one, and the scope of application is very wide.
