Abstract

The invention relates to precision instrument making. The aim of the invention is to improve the performance of measurements. The device comprises photoelectric sensors 8-11, a control signal generating unit and actuators 31-32. When the object deviates from the horizon plane, electrical signals characterizing this deviation are removed from the photoelectric sensors 8-11. After converting the electrical signals in the control signal generation unit, they arrive at the actuating elements, which bring the object into the horizon plane. 3 il.

The invention relates to precision instrument making and can be used to level objects and stabilize their horizontal position.

The aim of the invention is to improve the performance of measurements.

FIG. 1 shows the device section; in fig. 2 - the same, top view; in fig. 3 - functional device diagram.

The device consists of a housing 1, a rotating disk 2, a groove 3, a ball 4, a gear 5, an electric motor 6, a sensor 7 half-turn of the disk, photoelectric sensors 8-11 in the first, second, third and fourth quadrants, the source 12 of light, bearings 13, the light guide layer 14 in the channel 3. The quadrants are formed by the intersection of a circle, along the perimeter of which photoelectric sensors are placed, with two axes X and L, relative to which the object is horizontalized.

The housing 1 with the electric motor 6 is rigidly fixed on the stabilized object. In turn, on the housing 1, the sensor 7 half-turn of the disk and photoelectric sensors 8-11, which are located around the rotating disk 2, are rigidly fixed. The chute 3 is located in the disk along its diameter. The electric motor 6 provides rotation of the disk 2 with the groove 3 and the ball 4. The rotating disk 2 is fixed in the housing 1 by means of bearings 13, while having one degree of freedom relative to the housing 1. The light source 12 is installed in the center of the top cover of the groove 3 so that the central arrangement of the ball 4, the luminous flux from it had the opportunity to fall on all photoelectric sensors during a half turn of disk 2.

The functional diagram of the device includes photoelectric sensors 8-11, located respectively in the first, second, third and fourth quadrants, counters 15-18, adders 19-22, switches 23 and 24, registers 25 and 26, and code-to-voltage converters 27 and 28 , amplifiers 29 and 30, executive elements 31 and 32, sensor 7 half turn of a disk, delay lines 33 and 34.

The device works as follows.

When the object is horizontal, the ball 4 will be in the center of the groove 3, and thus the path for light to all photoelectric sensors will be free. As a result of the rotation of the disk 2 half a turn, all the photoelectric sensors 8-11 in all four quadrants will be illuminated. As a result, the amplitude of the electrical signal changes at the moment of illumination at their output. These signals arrive at the input of the counters 15-18. In this case, the readings of each cs meter will be the same and equal to the number of photoelectric sensors in each quadrant. Adders 19-22 will also calculate the same number of illuminated photoelectric sensors. Their number will be equal to the number of sensors located in two adjacent quadrants. In each of the subtractors 23 and 24, the subtraction of the readings of the two adders is performed, and therefore, since the readings are the same, the code at the output of the subtractors is zero. Registers 25 and 26 provide reception and storage of digital information removed from outputs of subtractors 23 and 24, cat / era obtained within 1/2 turn of disk 2. The code from the output of registers is zero, therefore, the voltage at the output of the converters is code - voltage Lives are also zero. This suggests that there are no control signals to the actuators.

When the object deviates from the horizon plane, the ball 4 will deviate from the center along the chute 3 and, due to the rotation of the disk 2, the ball will describe closed curves one for 1/2 of the turn of disk 2. Moving along the curve, the ball 4 blocks the light path to the individual photoelectric sensors depending on the direction of deviation of the object from the plane of the horizon. In this case, there will be no illumination of all photoelectric sensors, and consequently, the electrical signals at the outputs of non-illuminated sensors will not change. The readings of counters 15-18 will not be the same, therefore at the output of adders, subtractors and registers information will be different. It characterizes the direction of rotation of the object relative to the plane of the horizon. At the outputs of the code-voltage transducers, control electrical signals are generated, which are amplified in amplifiers 29, 30 and fed to actuators 31 and 32. Actuators apply moments to the object in such a way as to bring it to the horizon plane. Each actuator rotates the object relative to a single stabilization axis.

The sensor 7 half-turn of the disk resets the registers 25 and 26 before the device starts working and before each reception of the new information, which is formed after each half-turn of the disk 2, clocks their operation by means of the same signal passed through the delay line 33. The electrical signal from the output of sensor 7, passing through delay lines 33 and 34, also zeroed the counters 15-18 at the end of each half-turn of disk 2.

The proposed device provides for placing objects in the horizon with the help of hydro-stabilizers of power and indicator types, as well as objects that do not have hydro-stabilizers.
