Description

The inventive utility model relates to technology, namely, sensors that can determine the angle of inclination of objects, in one or two planes, in discrete mode. The inventive utility model can find application both as an independent product, and as a component in the creation of various systems used in robotics, in security alarms, in instrumentation, in automation means of ensuring safety in transport, in mechanical engineering, metallurgy, in others areas of human activity where it is necessary to determine the maximum angle of inclination of the object.

The closest in principle to the claimed utility model is a two-axis inclination sensor based on measuring the amount of ball movement caused by the sensor tilts relative to the horizon in two coordinates (RF patent 2191988, IPC G01C 9/10, priority from 12.07.2000 g). The sensor contains an electrically conductive ball housed in a sealed enclosure filled with a dielectric fluid, into which two pairs of electrically conductive plates are inserted and an electrically conductive axisymmetric thrust bearing having a concave spherical surface whose radius is larger than the radius of the ball that is mounted on this thrust bearing, and the ball and thrust bearing form the physical pendulum and the ball cover two pairs of electrically conductive plates, symmetry planes that are mutually orthogonal and pass through the axis of symmetry of the thrust bearing, on which The swarm also lies the center of the concave spherical surface of the plates.

The sensor provides continuous measurement of the angle of inclination in the range from 0 to 30 °.

The disadvantages of the known technical solutions are:

- a narrow range of measurement of tilt angles - from 0 to 30 °, due to the radial arrangement of the plates located in the rolling plane of the ball and limiting its course;

- unstable operation and a high probability of false readings when working in vibration. To smooth the vibration, it is proposed to use a damping fluid, however, small gaps between the ball and the plates do not allow stability to be achieved;

- the complexity of the implementation of this device is associated with ensuring high geometric accuracy of the surfaces of the thrust bearing with a concave spherical surface, the surfaces of the plates, the ball and providing the necessary clearance between them, and as a result, the high manufacturing cost.

The task was to develop a sensor for controlling the maximum angle of inclination with small overall dimensions, with stable output characteristics, which does not require additional settings, adjustments during operation, and provides tilt control of objects for various fields of application, including operation in harsh operating conditions.

The problem is solved in that in the sensor of the maximum angle of inclination of the inductive, including the housing with a cover. a chamber, a rolling surface, a rolling body, an active element, the housing is made of dielectric material or non-metal, the rolling surface is aligned with the inner surface of the housing, creating a camera in the housing of the housing, the active element is configured to create a sensitive zone and an output signal, and is an inductor , is located under the rolling surface, and it is possible to adjust the distance between it and the rolling surface, and the distance between the rolling body and the active element is determined T output value. In this case, the rolling body is made either in the form of a ball, or in the form of a cylinder, or in the form of a disk, and it can also be made either of magnetic metal, or of ferromagnetic metal, or of an amorphous metal, the rolling surface is made in the form of either a cone or a surface with a given curve, and to ensure stability during vibration, a damping fluid is placed in a chamber with a rolling body.

The technical effect of the claimed technical solution is to expand the functionality, simplify the design, reduce the cost, since the claimed utility model is built on the principles of using an elementary kinematic scheme, without complex mechanical and electrical components, which does not require expensive technologies and materials to be implemented. The inventive utility model allows you to control the maximum angle of inclination of the object, has reliability in operation, is easily integrated into existing automation systems of technological processes.

The inventive utility model allows you to create devices with low weight, with small overall dimensions, and if necessary, miniature, with stable output characteristics that do not require additional settings, adjustments during operation. This makes it possible to place them in various kinds of protective shells, cases, casing and seal them with compounds, obtaining products with a high degree of protection, up to IP68 according to GOST 14254-96 and above, vandal-resistant, with high performance characteristics, designed to work in harsh operating conditions:

- in conditions of high pressure;

- in the presence of vibration;

- in difficult climatic conditions;

- in aggressive environments;

- in conditions of elevated and lowered temperatures;

- in conditions of strong abrasive and mechanical influences.

 The claimed technical solution is illustrated by drawings.

The figure 1 pos. 1 shows a block diagram of a device for determining the angle of inclination where: 1 is the housing, 2 is the camera, 3 is the rolling surface, 4 is the rolling body, 5 is the active element, 6 is the sensitive area, 7 is the housing cover, 8 - damping fluid.

The claimed utility model works as follows.

An inductive tilt angle sensor monitors a given tilt angle, creating a discrete output signal. In the claimed utility model, in contrast to the prototype, the sensitive area and the varying output signal creates an active element created by an inductor and located below the rolling surface.

In the housing 1 with the cover 7, the rolling surface 3 is made in a certain way, while the rolling surface 3 is aligned with the inner surface of the housing 1, thereby creating a chamber 2 in the body of the housing 1. The housing 1 is made of dielectric material or non-metal. A rolling body 4 is placed on the rolling surface 3, which, under the action of its own gravity, is located at the lowest point - in the initial position. The rolling body can be made in the form of either a ball, or a disk or a cylinder, and the rolling surface can be made in the form of either a cone or a surface with a given curve.

The active element 5, which is an inductor, is installed below the rolling surface 3. The distances between the active element 5 and the rolling surface 3 are adjusted in such a way that ensures the presence of the rolling body 4 in its initial position in the sensitive zone 6. The output signal of the active element at this moment corresponds to the initial position of the rolling body. The camera 2 of the device is closed by a cover 7. To smooth out vibrations during vibration, a damping fluid 8 is poured into the chamber with the rolling body.

The location of the active element below the rolling surface allows you to remove the restriction to the movement of the rolling body 4 on the rolling surface 3 when the body is tilted, which increases the value of the controlled angle to 180 °. The angle α formed by the horizon plane and the rolling plane is equal to the limit angle of inclination for a particular device, and is set for each device individually, depending on the desired value of the controlled angle of inclination, and can be in the range from 0 to 180 °. When the sensor tilts the limit angle of inclination of the inductive figure 1, item 2, the angle a decreases between the rolling surface and the horizontal plane, and when it reaches a negative value, the rolling body 4 begins to move under the action of its own gravity and leaves the sensitive zone 6, which leads to change the value of the output signal of the active element 5, thereby signaling the excess of the allowable angle of inclination.

Changing the appearance of the rolling surface and the shape of the rolling body, the claimed utility model allows you to create a wide range of devices for determining the maximum angle of inclination, differing in characteristics and scope.
