By implementing the utility model, can obtain following useful technique effect: when this device cleans isolation switch contact, without equipment is stopped, use as a servant, and device has adopted spring and the winding clean cloth outside spring as cleaning part, utilized the characteristic of spring, when cleaning moving contact, spring is to two lateral bends, the elastic force of spring makes clean cloth contact closely with being cleaned, and has strengthened cleaning performance.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the overall structure schematic diagram after the utility model architecture advances;
Fig. 3 is structural representation when cleaning part does not wrap up scouring pad after the utility model architecture advances.
The specific embodiment
Understanding for the ease of those skilled in the art, is further described the utility model below in conjunction with specific embodiment:
As shown in Figure 1, a kind of isolating switch moving contact cleaning device, comprise insulating bar 1, support chip 2, support chip 2 two ends upsides are equipped with cleaning part 3 straight up, cleaning part 3 comprises spring and around the scouring pad on spring, support chip 2 lower ends are connected with insulating bar 1, and spring is hard spring, and the distance between two springs is less than isolating switch moving contact width and can guarantees that spring is after two lateral bends, and the distance of two springs can reach isolating switch moving contact width.By insulating bar 1, control cleaning, without the processing of ascending a height, without equipment is had a power failure, during use, only needing to control the scouring pad of winding in spring outside moves around in isolating switch moving contact both sides, utilize the characteristic of spring, when the scouring pad of winding in spring outside touches isolating switch moving contact front end, because isolating switch moving contact front end has curved portions, curved portions structure and the power inwardly applying mutually combine, make the scouring pad of winding outside spring to bending two ends, further, scouring pad can make scouring pad move in isolating switch moving contact front end curved portions and isolating switch moving contact two ends by spring, and remain with isolating switch moving contact when mobile and be close to, thereby only reaching moves around before and after needing, it is the object that isolating switch moving contact two ends and curved portions are cleaned up capable of washing, improved cleaning performance, and cleaning speed.
Further, as Fig. 2, Fig. 3, of the present utility model optimizing structure, support chip 2 two ends are provided with Elastic Cylindrical liquid storing barrel 5, liquid storing barrel 5 upper ends are provided with liquid storage lid 6, and liquid storage lid 6 is threaded connection with liquid storing barrel 5, and spring winding is in liquid storing barrel 5 outsides, liquid storing barrel 5 lower ends are connected with and are provided with tubule 7, and tubule 7 other ends are located at spring upper end.Open liquid storage lid 6, add cleaning liquid, cover liquid storage lid 6; In use procedure, spring is during to two lateral bends, 5 distortion of elasticity liquid storing barrel, after being extruded, the interior liquid of liquid storing barrel 5 sprays by tubule 7, liquid is distributed in Bai Jiebu by spring, and because tubule 7 is located at liquid storing barrel 5 lower ends, after liquid ejection, liquid storing barrel 5 is returned to after previous status, liquid storing barrel 5 sucks outside air, while guaranteeing liquid storing barrel 5 flexural deformation next time, can also spray liquid, thereby only reach, need in liquid storing barrel 5, pour into liquid, without repeatedly adding liquid to scouring pad, improved operating efficiency.For the ease of device, deposit and carry, there are many insulated connecting rods 101 to be formed by connecting insulating bar 1, insulated connecting rod 101 upper ends are provided with external screw thread, insulated connecting rod 101 lower ends are provided with the internal thread corresponding with external screw thread, support chip 2 middle parts are provided with the internal thread corresponding with external screw thread, while carrying, insulating bar 1 can be taken apart and deposited, and can be by adding or remove the length of insulated connecting rod 101 adjusting insulating bars 1.For the ease of cleaning isolating switch moving contact front end, between two springs, be connected with elastical cloth 8, elastical cloth 8 is provided with many cylindrical scouring pads that vertically arrange, when device moves forward and backward along isolating switch moving contact, scouring pad on winding spring cleans isolating switch moving contact two ends and curved portions, and scouring pad cleans isolating switch moving contact front end on while elastical cloth 8, so only need move forward and backward a kind of operation, can realize isolating switch moving contact is cleaned comprehensively.Further, insulating bar 1 is provided with the link of support chip 2 the U-shaped protection piece 9 that Open Side Down, by protection piece, prevents that on-insulated cleaning fluid or rainwater etc. from flowing through insulating bar electric conduction phenomena occurs.For the clearer situation of seeing isolating switch moving contact of energy when working, support chip middle part is provided with through hole 201, can have better sight line, convenient operation, and can save material.
