Устройство содержит корпус 1, в котором подвешен маятник 2 с возможностью свободного отклонения в взаимно перпендикулярных направлениях,а в нижней своей части имеет в качест- 15 ве графитационной массы П-?образный 'ферритовый сердечник 3, на одном стержне которого закреплена'вторичная обмотка 4. Каркас 5 с обмоткой возбуждения 6 крепится к корпусу 1 20 устройства. Вторичная обмотка 4 и обмотка возбуждения 6 являются элементами автогенератора /, сигнал с которого поступает на индикатор 8. Каркас 5 обмотки возбуждения 6 выпол-25 нен таким образом, что второй стержень П-образного сердечника 3 может свободно перемещаться в взаимно перпендикулярных направлениях внутри каркаса 5. 30The device comprises a housing 1, in which a pendulum 2 is suspended with the possibility of free deflection in mutually perpendicular directions, and in its lower part has a graphitic mass of a U-shaped 'ferrite core 3, on which one secondary winding 4 is fixed Frame 5 with field winding 6 is attached to the housing 1 20 of the device.

Устройство работает следующим образом.The device operates as follows.

При наклоне объекта, а, следовательно, и устройства, закрепленного на нем, в плоскости измерения маятник стремится сохранить свое вертикальное положение под действием гравитационной массы, а закрепленный на корпусе 1 каркас 5 с обмоткой возбуждения 6 перемещается относительно П-образного сердечника 3, изменяя как величину индуктивной обмотки 6, так и коэффициент трансформации между ними. А так как обмотки 4 и 6 являются элементами автогенератора 7, то на его выходе появляется напряжение и частота, пропорциональные углу наклона объекта.When the object, and, consequently, the device mounted on it, is tilted in the measurement plane, the pendulum tends to maintain its vertical position under the influence of the gravitational mass, and the frame 5 mounted on the housing 1 with the excitation winding 6 moves relative to the U-shaped core 3, changing how the magnitude of the inductive winding 6, and the transformation coefficient between them. And since the windings 4 and 6 are elements of the oscillator 7, then voltage and frequency proportional to the angle of the object appear at its output.

Неровность поверхности объекта или его конусность не влияют на точность измерения, так как каркас 5 свободно перемещается относительно стержня П-образного сердечника 3 в взаимно перпендикулярных направлениях.Roughness of the surface of the object or its conicity does not affect the measurement accuracy, since the frame 5 moves freely relative to the rod of the U-shaped core 3 in mutually perpendicular directions.

Включение обмоток 4 и 6 в схему автогенератора позволяет значительно снизить потребляемую мощность от источника питания и, тем самым, применить автономный источник питания, например, от элементов 373, что позволяет производить определение углов отклонения от вертикали различных объектов в полевых условиях.The inclusion of windings 4 and 6 in the circuit of the oscillator can significantly reduce the power consumption from the power source and, thereby, apply an autonomous power source, for example, from elements 373, which allows the determination of the angles of deviation from the vertical of various objects in the field.

Claims

The invention relates to a measuring technique, in particular, to devices for determining the angle of inclination of an object relative to a horizon or vertical. There are known devices for determining the angle of inclination of an object, which contain an indicator made of ferromagnetic material and interacts with an inductance coil mounted on a housing connected to the oscillator Cl. Devices are known for determining the angle of inclination of objects containing a skeleton, a thumbnail in the form of a segment of a ring ferrite with a winding of excitation and secondary windings t2. The disadvantages of such a device are low sensitivity. Especially, this factor affects the measurement of the angle of inclination of an object having a lateral surface not perpendicular to the horizontal (for example, a conical one). It is necessary to use an external generator, therefore, the power consumption increases. The closest to the proposed technical essence and the achieved result is a device for determining the angle of deviation from the vertical, comprising a housing, a tang with a magnetic pipe, an auto-generator with an excitation winding and a secondary winding, a suspension system of the tandem, and an HS indicator. consumed energy. This goal is achieved by the fact that in a device for determining the angle of deflection of objects from the vertical, comprising a housing, a tandem with a magnetic core, an auto-generator with an excitation winding and a secondary winding, a free suspension system of the master and an indicator, the secondary winding of the auto-generator is placed on one of the magnetic core bars, having a 39 U-shaped, and the winding of the excitation is placed on the frame, mounted on the device, with the possibility of free movement of the rod of the U-shaped magnetic circuit and the secondary quipment in mutually perpendicular planes. FIG. 1 shows a device, a general view, in FIG. 2 - frame, general view. The device includes a housing 1 in which a tandem 2 is suspended with the possibility of free deflection in mutually perpendicular directions, and in its lower part has a ferrite core 3 on a single rod of which the secondary winding is fixed as a graphitic mass P. Frame 5 with the field winding 6 is attached to the housing 1 of the device. The secondary winding k and the excitation winding 6 are elements of the oscillator J, the signal from which is supplied to the indicator 8. The frame 5 of the excitation winding 6 is designed so that the second rod of the U-shaped core 3 can freely move in mutually perpendicular directions inside the frame 5. The device operates as follows. When the object is tilted, and, consequently, the device attached to it, in the plane of measurement, the bowner tends to maintain its vertical position under the action of the gravitational mass, and the frame 5 fixed to the housing 1 with the excitation winding 6 moves relative to the U-shaped core 3, changing both the magnitude of the inductive winding 6, and the transformation ratio between them. And since 6 and are the elements of the auto-oscillator 7, a voltage and frequency proportional to the angle of inclination of the object appear at its output. 1 Unevenness of the surface of the object or its taper does not affect the measurement accuracy, since the frame 5 freely moves relative to the rod of the U-shaped core 3 in mutually perpendicular directions. The inclusion of windings 4 and 6 in the circuit of the auto-generator allows to significantly reduce power consumption from the power source and, thus, use an autonomous power source, for example, from elements 373, which allows defining the angles of deviations from the vertical of various objects in field conditions. x Apparatus of the Invention A device for determining the angle of deviation of an object from a vertical, comprising a housing, a master with a magnetic core, an auto generator with an excitation winding and a secondary winding, a free suspension system of the master and an indicator, characterized in that, in order to increase the sensitivity and decrease power consumption, the secondary the autogenerator winding is placed on one IU of magnetic cores having a U-shape, and the field winding is placed on a frame fixed on the device body with the possibility free movement of the rod U-shaped magnetic circuit and the secondary winding in mutually perpendicular planes.
