Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The device for sending the separating and combining position signal of the isolating switch is characterized in that a mechanism output shaft 2 is arranged on a bottom plate 7, one end of the mechanism output shaft 2 is connected with a power mechanism, a gear A4 is arranged at the other end of the mechanism output shaft through the bottom plate 7, the gear A4 is meshed with a gear B3, the axle center of the gear B3 is connected with a cam 5, and a dial 6 is arranged on the cam 5; the base plate 7 is provided with two groups of micro-switch groups, each group of micro-switch groups comprises two micro-switches 9, the micro-switches 9 correspond to the peripheral positions of the cams 5, and the rotating positions of the cams 5 are detected.
The bottom plate 7 is provided with a gear support shaft 1, and the gear support shaft 1 is parallel to the axis of the mechanism output shaft 2. The end part of the gear support shaft 1 is sleeved with a bearing 8, and the periphery of the gear B3 is embedded in a groove at the periphery of the bearing 8. Thereby, the supporting force is provided to the gear B3 by the gear supporting shaft 1.
The periphery of the cam 5 is of an upper-lower two-layer structure, and the heights of a group of two microswitches 9 respectively correspond to the heights of the cams 5 at the positions to be detected. The micro switch groups are symmetrically arranged on two sides of the circumference of the cam disc in a group of every 2.
The specific use is as follows:
the motor receives electricity and drives the mechanism output shaft 2 to rotate through a transmission link, and the cam 5 is driven to rotate in a certain angle direction through the meshing of the gear A4 and the gear B3. The cam 5 is constructed as shown in fig. 5 and 6, and has two grooves formed on the outer circumference thereof, and the left and right sides are formed by a height difference. The horizontal positions of the two groups of micro switches 9 correspond to the positions of the two grooves of the cam 5, and the height position of each micro switch corresponds to the height position of the outer circumference of the cam 5 to be detected. When the cam 5 rotates a certain angle and the outer edge of the cam 5 touches the micro switch, the position state of the isolating switch is sent when the micro switch is at the opening/closing position of the isolating station, which represents that the isolating side body contact is in position. When the micro switch at the opening/closing position of the grounding station is contacted, the position state of the grounding switch is sent to represent that the grounding side body contact is opened and closed in place.
