The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1 and 2, an interlock apparatus for an earthing switch and a cabinet door comprises: an operating member 100, the operating member 100 being used to turn and trigger the grounding switch, the operating member 100 being provided with a driving portion; locking mechanism, locking mechanism include locking piece 200, and the one end butt of locking piece 200 is in drive part, and the other end of locking piece 200 can be towards the locking hole 300 on the cabinet door, and under the rotation of operating parts 100, drive part drive locking piece 200 combines together with locking hole 300 with locking cabinet door or phase separation in order to unblock cabinet door.
The interlock of earthing switch and cabinet door of above structure, when the cabinet door is closed the back and need be to equipment circular telegram, rotate operating parts 100 and trigger earthing switch to make earthing switch separating brake, at this moment, the drive division is followed operating parts 100 and is rotated in step, and then drives the locking mechanism motion, so that locking piece 200 removes and is close to the cabinet door, and locking hole 300 on final locking piece 200 and the cabinet door cooperatees in order to hinder opening of cabinet door, thereby guarantees the safe operation of equipment. Similarly, when equipment need overhaul, with earthing switch operating axis switching power take off earthing switch to make earthing switch combined floodgate, at this moment, driving piece drive link mechanism resets, and then drives locking piece 200 and locking hole 300 phase separation so that the cabinet door can be opened again, thereby guarantees maintainer's safety. The interlocking device of above structure, simple structure is compact, and spare part is few, and is with low costs, and only need carry out independent control to operating parts 100, can carry out the switching of locking and unblock state to the cabinet door, convenient operation, and the interlocking is reliable.
Particularly, the cabinet door is cable chamber door, and wherein, the top of cable chamber door is provided with the flat board that parallels with the top cap of cable chamber, and locking hole 300 runs through top cap and flat board, only needs locking piece 200 to wear to locate locking hole 300 promptly, alright make cable chamber door unable rotation open.
Referring to fig. 1 and 2, in some embodiments of the present invention, the operation element 100 is a shaft, the driving portion is a cam 110 protruding and extending along the outer circumference of the shaft, the locking mechanism further includes a mounting member 210 and an elastic member 220, the locking member 200 is movably disposed on the mounting member 210, one end of the locking member 200 abuts against the cam 110, one end of the elastic member 220 is connected to the mounting member 210, and the other end of the elastic member 220 is connected to the locking member 200. Specifically, when the operating element 100 rotates to the ground switch to open, the cam 110 pushes the locking member 200 to move toward a side close to the locking hole 300, so that the locking member 200 is inserted into the locking hole 300 to lock the cabinet door, and meanwhile, the locking member 200 stretches the elastic member 220; when the operating element 100 rotates to the ground switch to be switched on, the elastic element 220 drives the locking element 200 to reset by the elastic acting force of the elastic element, so that the locking element 200 is separated from the locking hole 300, and the cabinet door is unlocked. The elastic member 220 facilitates the locking member 200 to be always abutted against the cam 110, and the movement is reliable and stable. It is understood that the cam 110 may be a disc cam 110, and the disc cam 110 is a disc member rotating around a fixed axis and having a varying radial direction, and has a simple structure and is convenient to operate.
Referring to fig. 1 to 3, in some embodiments of the present invention, the locking member 200 includes a plate portion 201, one of the plate portion 201 and the mounting member 210 is provided with a guide channel 202 extending from the operating member 100 toward the locking hole 300, and the other is provided with a limit shaft portion 211 capable of sliding back and forth in the guide channel 202. Wherein, guide channel 202 cooperatees with spacing axial region 211, is favorable to improving the stationarity of the removal of lock piece 200. It is understood that the guiding channel 202 can be an elongated through slot adapted to the limiting shaft portion 211, and the width diameter of the elongated through slot is slightly larger than or equal to the diameter of the limiting shaft portion 211, so as to facilitate the limiting of the locking member 200 and improve the smoothness of the movement of the locking member 200.
Referring to fig. 1 and 2, in some embodiments of the present invention, two limiting shaft portions 211 are provided, and the two limiting shaft portions 211 are distributed in a direction from the operation member 100 to the locking hole 300. Two spacing axial region 211's setting for improve the stationarity and the straightness that lock piece 200 removed, reduce the positional deviation who removes. It is understood that the distance between the two stopper shaft portions 211 and the two ends of the guide passage 202 is greater than the distance between the lock member 200 and the lock hole 300, so that the moving stroke of the lock member 200 can be satisfied.
