Abstract
The invention discloses an automatic energy compensation type single pendulum device. A hollow slide is embedded to a certain position of a screw rod through a screw; the upper end of the screw rod is a free end, while the lower end is coaxial with a step motor; a drive control module is connected with the step motor through a swing sensor; when a pendulum mass swings to a maximum displacement position, the swing sensor triggers the drive control module to drive the step motor to rotate so as to drive the slider to slowly descend and then quickly ascend; and when the pendulum mass swings to a maximum displacement position on the other side, the swing sensor triggers the same action once again, so the single pendulum is driven to swing for a long time. The drive control module comprises a power source, a controller and a driver; and the rotating speed and rotor angle of the step motor are controlled by pulse frequency and pulse number, so the upper limit position and the lower limit position of the slider are kept unchanged, the process of slow descent and quick ascent is realized, and the energy loss of the single pendulum in the swing process is effectively compensated. The device has a simple structure and stable performance, and is convenient to use.

Embodiment
Below in conjunction with accompanying drawing, introduce embodiment of the present invention in detail.
Shown in Fig. 1-2, the present invention includes single pendulum system 5 and drive control module, oscillation gauge 7 is set in single pendulum system 5.Wherein, drive control module comprises power supply 1, controller 2 and driver 3; Power supply 1 links through controller 2 and driver 3, and drive control module links through oscillation gauge in datawire 4 and the single pendulum system 57 and stepper motor 15; The upper end of single pendulum system 5 is poles 6, and pole 6 is propped or hung, and pole 6 links with pendulum mass 9 through two one metal wires 8.
Like Fig. 3 and shown in Figure 4; Screw rod 11 is coaxial with stepper motor 15, is carved with helical groove 12 on the screw rod 11, and screw rod 11 passes hollow slide block 13; Hollow slide block 13 centers are equipped with screw 14, and the interior part at hollow slide block 13 of its screw 14 places in the helical groove 12 of screw rod 11.The upper end of link 16 and equalizer bar 10 are fixing; Lower end and stepper motor 15 shells are fixed, and its hollow core slide block 13 is an elliptical cylinder-shape, and itself and 16 of links leave the gap; And the distance of hollow slide block 13 and link 16 is less than the length of its major semi axis; Thereby guarantee that hollow slide block 13 can not rotate, and can only move up and down when screw rod 11 rotations.
As shown in Figure 5, power supply 1 is the DC electrical source that the 220V Ac is transformed into 24V, and driver 3 model 2024B2, its pin B15 and B16 are received the output terminal of power supply 1 by two leads; Controller 2 model C NC, it directly is connected with the 220V ac power supply, and its pin CP0, DIR0 and OPTO link to each other with the pin B07-B09 of driver 3 respectively; The pin OUT1 of controller 2 links to each other with oscillation gauge 7 with wire 8 respectively with GND, and two parallel wires 8 link to each other at equalizer bar 10 places, when oscillation gauge 7 contacts with wire 8, promptly connect circuit; The pin B11-B14 of driver 3 links to each other with stepper motor 15 through datawire 4.
The working principle of single pendulum system is: energized 1, depart from pendulum mass 9 about 10 degree of equilibrium position, after the relieving; When putting to maximum displacement place, wire 8 contacts with oscillation gauge 7, thus the conducting drive control module; Controller 2 makes driver 3 order about stepper motor 15 and is rotated counterclockwise (seeing from the top down); Slowly descend thereby drive hollow slide block 13, move certain displacement after, controller 2 controlling and driving devices 3 order about stepper motor 15 turn clockwise (seeing from the top down); Thereby drive hollow slide block 13 fast rise, at this moment pendulum mass 9 does not also arrive another side maximum displacement place; When pendulum mass 9 to opposite side maximum displacement place wire 8 contacts with oscillation gauge 7; Trigger controller 2 controlling and driving devices 3 and order about stepper motor 15 counterclockwise or turn clockwise (seeing from the top down); Thereby driving slide block slowly descends; Fast rise triggers pendulum mass 9 at every turn and can obtain certain energy subsequently, thereby realizes swing for a long time.
