Detailed Description

the invention is further described with reference to the drawings and the detailed description.

As shown in fig. 1 to 6, the utility model comprises a correcting plate, a base 5, a shell 1, a column 3, a motor 2 and a cylinder 4.

The edge of the base 5 is provided with three upright post holes 7, the positions of the upright post holes 7 on the lower surface of the base 5 are respectively fixedly provided with a cylinder 4, and the central hole of the cylinder 4 has the same shape as the upright post holes 7 to form an integral through hole. The upright post holes 7 are respectively provided with an upright post 3. The upright post 3 is of a quadrangular prism structure, and the upright post hole 7 is a quadrangular hole body matched with the upright post 3, so that the upright post 3 can move up and down freely and cannot rotate. A motor 2 is fixedly arranged at each upright post hole 7 on the upper surface of the base 5, and an output shaft 6 of the motor 2 is a threaded rod and is positioned in the upright post hole 7. The axis of the upright post 3 is provided with a threaded hole 8 matched with the output shaft 6 of the motor, and the lower half part of the output shaft 6 of the motor is positioned in the threaded hole 8. The starting motor 2 can drive the upright post 3 to move up and down, so that the levelness of the base 5 can be adjusted.

The shell 1 is fixed on the upper surface of the base 5, one side wall of the shell 1 is a correction plate, and the correction plate is perpendicular to the base 5. The weight 10, the rope 9, the mirror 11 and the photosensitive sensor 12 are arranged in the shell 1. The upper end of the rope 9 is fixed on the upper wall of the shell 1, and the heavy hammer 10 is fixed on the lower end of the rope 9. The weight 10 is provided with a laser, a mirror 11 is obliquely arranged below the laser, and a series of photosensitive sensors 12 are arranged beside the mirror 11. Laser light emitted by the laser is reflected by a mirror 11 and then projected onto a photosensitive sensor 12. In the optimization scheme, the mirror 11 is a convex mirror, laser irradiates on the convex mirror, the position irradiated by the laser changes when the base 5 inclines, the convex mirror has a divergence effect, and when the position irradiated by the laser slightly changes, the reflection angle of the laser greatly changes under the divergence effect of the convex mirror, so that the change of light can be detected, namely, the change of the angle of the base 5 can be accurately detected. The photosensitive sensors 12 include 7 groups, which are arranged as shown in fig. 5, wherein a group of sensors 12 is located at the center, and b-g groups of sensors 12 are uniformly distributed on the periphery of the group of sensors 12. When the base 5 is in a horizontal state, the reflected laser light is irradiated on the a-group sensor 12; when the base 5 is inclined, the laser irradiates on other groups of sensors 12; the system is thus able to detect the condition of the base 5 and thus control the rotation of the corresponding motor 2, adjusting the extension of the upright 3 until the base 5 is adjusted to the horizontal condition.

In the optimization scheme, in order to prevent interference caused by other photosensitive sensors 12 after laser light is subjected to a series of diffuse reflection in the shell 1, the inner wall of the shell 1 is coated with black, so that light rays after diffuse reflection can be absorbed. In order to prevent the housing 1 of the weight 10 from swinging for a long time, a transparent liquid can be injected into the housing 1, the liquid does not affect the transmission of the laser, and the mechanical energy of the weight 10 can be consumed by friction resistance when the weight moves, so that the weight is prevented from swinging for a long time.

The utility model discloses the circuit connection relation is as shown in fig. 6, b ~ g group sensor in, motor 2 is controlled jointly to two sets of relative sensors, wherein driving motor 2 corotation behind 12 sensitization of a set of sensor, driving motor 2 reversal behind another group's sensor sensitization, the function of the automatic level correction of base 5 has been realized through the motion of these six group sensors 12 common control motor 2. The group a sensors 12 are connected with the indicating lamps, when the group a sensors sense light, the base 5 is in a horizontal state, the indicating lamps are turned on to remind relevant personnel that the base 5 has completed the automatic leveling process, and the correction plate is located on a vertical plane.

It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
