Space of the prior art inclination detecting device, as utilize the plumb aligner of gravity principle design can measure the inclination angle, but energy measurement vergence direction not are difficult to satisfy actual needs.Though existing gyroscope can be measured inclination angle and vergence direction simultaneously, its production cost height, working service complexity.

The utility model content

The utility model is exactly the space inclination angle detection instrument that a kind of simple in structure, easy to operate, low production cost is provided at the problem that above-mentioned prior art exists, and this space inclination angle detection instrument can be measured inclination angle and vergence direction simultaneously by single reading.

The technical scheme that the utility model provides is: space inclination angle detection instrument, comprise shell, be fixed with index dial on the shell, the index dial center is provided with adjusting knob, the adjusting knob below is hung with horizontal pointer and light-emitting component, and adjusting knob, horizontal pointer and light-emitting component connect by messenger wire.

Above-mentioned shell is rectangular parallelepiped or right cylinder etc.

Above-mentioned index dial is marked with a series of concentric circless, and circumference is marked with the angle value of expression vergence direction, and each concentric circles is marked with the angle value of expression inclination angle size.

Above-mentioned adjusting knob center, pointer center, light-emitting component center are on same pedal line.

The utility model adopts said structure, constitute vertical (if light-emitting component is lighter by adjusting knob, horizontal pointer and light-emitting component, can be at additional mass under the light-emitting component), the light that sends by light-emitting component projects to horizontal pointer on the index dial, according to the projection of pointer on index dial, can measure the inclination angle and the vergence direction of the utility model space inclination angle detection instrument, when the utility model is fixed or during near measurand, then can be measured the inclination angle and the vergence direction of measurand.The utility model is simple in structure, easy to operate, low production cost, by single reading (inclination angle of mark value and vergence direction value on the index dial), can measure inclination angle and vergence direction simultaneously.

Embodiment

Referring to Fig. 2, Fig. 3, the utility model comprises rectangular parallelepiped (or right cylinder) shell 6, is fixed on the translucent index dial 1 on the shell, can be at the adjusting knob 9 of index dial 1 center rotation.Messenger wire 2 upper ends are fixed on the center of adjusting knob 9 and can rotate with adjusting knob 9, and simultaneously, messenger wire 2 can freely swing around the O point.Messenger wire 2 lower ends are passed and are fixed in the tubular shaft 4, and pointer 3 center fixation are on tubular shaft 4, and pointer 3 is vertical with tubular shaft 4.Messenger wire 2 lower ends are divided into four, and four messenger wires pass on the suspension ring 5 equally distributed four apertures respectively and are fixed on the suspension ring 5, and guarantee suspension ring 5 levels, and little electric torch 7 passes suspension ring 5 centers and is suspended on the suspension ring 5.

Index dial 1, adjusting knob 9, messenger wire 2, pointer 3, tubular shaft 4, suspension ring 5 and little electric torch 7 are formed a rotating and projection vertical, and wherein, pointer 3 remains horizontality, and rotation adjusting knob 9 can make pointer 3 rotate in surface level.The light that bulb 8 sends projects to pointer 3 on the index dial 1.When index dial 1 produced the space banking motion, the projection of pointer 3 on index dial 1 changed thereupon.Pointer 3 projections are by index dial 1 center dimidiation: projected length is short is called short projection.Rotation adjusting knob 9 makes pointer 3 short projected lengths the shortest, is called the shortest projection.

Index dial 1 is marked with a series of concentric circless, and circumference evenly is divided into some five equilibriums, and puts on angle value, is called vergence direction 11, and each concentric circles subscript upper angle value is called inclination angle 12.On the index dial 1 the direction of short projection equal the vergence direction of index dial 1.

On the index dial the length of short projection and the relation between the index dial inclination angle as shown in Figure 4, L wherein ₁Be the fulcrum O of messenger wire distance, L to pointer ₂Be the distance of pointer to bulb, 2r is the length of pointer, and α is the inclination angle.The shortest projection of pointer on index dial is divided into R and R ' two parts by index dial central point O, because long projection may exceed index dial, calculates (R is the shortest projection) so get R.Among Fig. 4, can get according to the sine in the trigonometric function:

$R=\frac{({\mathrm{<figure-callout\; id="1"\; label="L"\; filenames="Y20072008423900072.png"\; state="\{\{state\}\}">L</figure-callout>}}_1+L_2)\sin \mathrm{\&theta;}}{\cos (\mathrm{\&theta;}-\mathrm{\&alpha;})},$ $\mathrm{\&theta;}=\arctan \frac{r}{L_1}---\left(1\right)$

The inclination angle changes, and R changes thereupon, and when OE ⊥ AE, the R minimum is designated as R _Min, this moment, corresponding inclination angle was designated as α _MaxAs 0≤α≤α _Max, α is corresponding one by one with R.In the interval [0, α _Max] in evenly get some angles, be designated as 0 respectively, α ₁, α ₂... α _Max, they are brought into (1) formula respectively, can obtain the shortest corresponding projected length, be designated as R respectively ₀, R ₁, R ₂... R _MaxRespectively with R ₀, R ₁, R ₂... R _MaxBe that radius draws concentric circles, and the inclination angle 12 of correspondence is marked on the circular arc, corresponding inclination angle of each concentric circles then, as shown in Figure 3 (0,10,30 etc.).

Plane with 240 ° of 10 ° of vergence directions in measurement inclination angle is an example, and rectangular parallelepiped of the present utility model (or right cylinder) bottom surface is placed in the plane, and pointer 3 remains horizontality, and the light that bulb 8 sends projects to pointer 3 on the index dial 1.Rotation adjusting knob 9 rotates pointer 3 in surface level, the projection of pointer 3 on index dial 1 changes thereupon.The shortest when pointer 3 short projected lengths, adjusting knob 9 promptly stops the rotation.Can read the inclination angle this moment according to the shortest projection indication of pointer on index dial is that 10 °, vergence direction are 240 ° (referring to Fig. 5).
