Description

The invention relates to a control and measuring technique, to chesnosgi, to devices for measuring the angles of inclination of structures or soil under the influence of disturbances caused by an explosion or ground.

years old

It is known that at earth mts and explosions, the ground and the coils sunk in it (marrying the transition in aviation, which can occur during a comparative period of time. One of the parameters of that movement is the angle of inclination of the soil or construction For the measurement of the angles of the wafer are widely used on the base of the vertical plumb line.

There are well-known hydrophometer tiltmeters consisting of a body filled with liquid, in the lower part of which there are built-in viewing pins on two opposite sides, and in the uppermost one there is a tic toe. On the tomb float and arrow are placed. A double-sided scale is installed inside the case, which is viewed through the sight glasses. The housing is mounted on a square with a right angle.

In this triborina OLYA, of increased resolution, the float is reinforced, on the lower part of the t-shirt, a gravity center that is located below the fulcrum. The resolution of the device's cnocofeocTb can be controlled by moving the float on the tandem and by collecting the spring stiffness. The value of ein from the vertical or horizontal is apreaeoing put on a scale visually, by applying a selection to the vertical or horizontal angle: coal or a plane with an alternative plane.

This procedure does not allow for remote removal in the forma- tion, which is a distraction from the factories in explosions, especially in the gland of the soil massif.

A device is known for you at the angle of inclination under conditions of pressure and ample overload, which includes a body, a float completely immersed in a liquid, a suspension of the float, and a system for distractioning the mold. The float is made into a clear hollow xjus, the top of which is connected to the base of the body with the help of a two-stage charvier, and in the upper part of the yspen is a cross, the rods of 113 ferromagnetic material enter into the axial orifices of the coils of the chi duo transducer. Device high threshold sensitivity

The closest in terms of technical dryness and constructive implementation to the proposed invention is a device for determining the angle of inclination of an object in two mutually perpendicular planes xd in which the tandem suspension is made on a hinged cross, and the arrows are rigidly fixed at their ends are ferromagnetic cores of transducers of the overtarget, and their inductance coils are spaced directly on the tandem to measure the angle of inclination of one component and at the hinge pillars Ah, the crosspieces of the cross are used to measure the angle of inclination of the other component h.

However, the threshold sensitivity of the known device when measuring small angles is also insufficient.

The aim of the invention is to increase the threshold sensitivity of the device.

This goal is achieved by the fact that in a device for determining the angle of inclination of an object in two mutually piped cool planes containing a fully immersed in liquid and suspended freely at the hinge of the bottom plate, in the lower part of which are placed ferromagnetic sertechnikn, interacting with angle converters tilting into an electric signal, a tambourine with an abgen toroidal float, the horizontal axis of symmetry of which is aligned with the axis of the tandem suspension, and rigidly locked on it.

With such an execution of the tiller by the time of the suspended tiller, which has tended to maintain its vertical position when the object is tilted, a moment of a toroidal float rigidly fixed on it, tends to maintain its horizontal position, is added. These; moments operate in the same direction and increase the threshold sensitivity of the sensor. The overall dimensions of the sensor P {81 do not increase.

FIG. 1 shows the sensor,. view; in utr, 2, section A-A in FIG. one; FIG. 3 is a section BB in FIG. one.

The device contains chic 1, pop-up on a hinged cross 2, which is an axis perpendicular to the axis, which provides information on angles and direction of inclination in the entire range of measurements 2, The disadvantage of this device is 5. with the fact that it does not possess enough

the rotation of the tandem, eeshreshyun in the bearings of the uprights 3, belonging to the intermediate shell 4, resting on the annular protrusion of the housing 5. In the lower part of the tambour is fixed the crosspiece 6c by ferromagnetic cores 7, located in two mutually perpendicular planes and interacting with inductors 8 , fixed in the bottom of the bachyka 4. Between the core and the inner pysyurity of the coil, forming a transducer of the angle of inclination into an electrical signal, there is a gap equal to the course of the trough of this radius naklova maximum predetermined angle. In the connection from the coils, there is a plug S 9, the internal volume of the gun is closed with a sucker nut 10. The tor4l1alvy float 11 is fixed on. 12, in accordance with the speech of oam oovvesa ma taik.

The device works Next

; When the structure is inclined, which is caused by an explosion or an earthquake, the body of the device attached to it also tilts by the same angle and

The tilting plane is deflected and the scaffold. Cores fixed in the lower part of the MVT (a, measure their location relative to their coils, and the electrical signal received at the output of the coils,

10 connected in pairs according to a differential scheme is proportional to the core mixing, and, therefore, to the angle of inclination. It should be noted that the inductance of the coils, in which the cores are mixed with across the axis of the coils, is practically not replaced by clogs, and the signal on these coils is not recorded. A similar picture is observed in the plane perpendicular to the one described.
