Embodiment
The present invention includes deciliter restrictor bar 16, deciliter restrictor bar 16 described in its structural feature is connected with connecting rod 15, and one end of connecting rod 15 is connected with down-pressed pole assembly 18, and the other end of connecting rod 15 is connected with lifting arm assembly 13.
Described lifting arm assembly 13 comprises horizontal lifting bar 12, is provided with the first fixed rotating shaft 11 in the middle part of horizontal lifting bar 12; One end of horizontal lifting bar 12 is connected by vertical lifting bar 14 connecting rod 15 one end with deciliter restrictor bar 16; The other end of horizontal lifting bar 12 is corresponding with cam 2; Described cam 2 is connected with having the motor storing power spring, and cam 2 surface is provided with spacing 3; Described spacing 3 one end with L shape keeper 4 is corresponding, and the turning point of L shape keeper 4 is provided with positioning rotating shaft 7, and the other end corresponding to L shape keeper 4 is provided with combined floodgate iron core 6; Described horizontal lifting bar 12 is provided with roller 5, roller 5 is provided with curved bar 9, in the middle part of curved bar 9, be provided with separating brake rotating shaft 8; Curved bar 9 one end is provided with draw-in groove corresponding to roller 5, and the other end of curved bar 9 is corresponding with separating brake iron core 10.
Described down-pressed pole assembly 18 comprises with the connected depression bar 17 of connecting rod 15 other end of deciliter restrictor bar 16, and the end of depression bar 17 is arranged on the second fixed rotating shaft 20; In the middle part of depression bar 17, top is provided with thrust spring 19.
Described horizontal lifting bar 12 is provided with pulley 1 corresponding to cam 2.
Embodiment: the length of described horizontal lifting bar 12 is 125mm, the length of vertical lifting bar 14 is 90mm, and the length of deciliter restrictor bar 16 is 115mm, and the length of depression bar 17 is 180mm.
Because the present invention is rational in infrastructure, the overall volume of the side-mounted high-pressure vacuum breaker made according to the technical scheme described in above-described embodiment is: wide 310mm, high 500mm, dark 860mm.
Commercially, not little again than this mechanism so far mechanism.
Below in conjunction with accompanying drawing, one-off process of the present invention is described: as shown in the figure, first, driven by motor cam 2 rotates, and collide in spacing 3 of cam 2 and positioning key one end of L shape, motor is by storing power spring stores energy.
When needing to close a floodgate, combined floodgate iron core 6 moves, promote the other end of L shape keeper 4, it is made to rotate clockwise around positioning rotating shaft 7 turns, L shape keeper 4 is with spacing 3 disengagement of cam 2, the clockwise under influence that cam 2 is storing power spring rotates, and contact with the pulley 1 of horizontal lifting bar 12 left end, the left end of horizontal lifting bar 12 is pressed down, horizontal lifting bar 12 rotates counterclockwise around the first fixed rotating shaft 11, and vertical lifting bar 14 is promoted, vertical lifting bar 14 drives deciliter restrictor bar 16 to rise by connecting rod 15, realizes closing a floodgate; While horizontal lifting bar 12 rotates counterclockwise, the roller 5 that its surface is arranged slips in the draw-in groove of curved bar 9, is fixed, and keeps the state of closing a floodgate.
