Put " and " a kind of 550 isolation earthing switch division instruction devices ", there is provided the solution of division instruction, can not realize at the same time
Remote signal is transmitted and site instructions observation.
The present invention bases oneself upon the demand of combined electrical apparatus and the deficiency of current technology, there is provided a kind of extendible capacity formula earthing switch division
Signal is changed and instruction device, possess it is simple in structure, occupy little space, synchronous transfer remote signal and realize the spy of on-site-inspection
Point, and have the advantages of auxiliary switch dilatation facilitates concurrently.
The content of the invention
It is an object of the present invention to provide one kind be easy to dilatation, it is simple in structure, occupy little space, signal transmission is accurate, conveniently
The signal conversion driving unit of ground observation.
To realize above-mentioned function, it is as follows that the present invention provides a kind of technical solution：
The feature that the present invention is driven is：It is made of auxiliary switch, rocking arm, connecting plate, direction board, observation window, it is simple in structure；There is two-stage
Transmission mechanism is synchronized with the movement, and realizes the signal synchronous transfer of two auxiliary switches；Direction board is direct-connected with transmission mechanism, realizes up and down
Move back and forth；When the observation window reading direction board fixed by position moves to diverse location, direction board and observation window centering area
Domain shows information；By increasing transmission mechanism in relevant position of the present invention and auxiliary switch realizes auxiliary switch dilatation.
Brief description of the drawings
Fig. 1 is drive mechanism schematic diagram of the present invention.
Fig. 2 is site instructions of the present invention and observation schematic diagram.
Fig. 3 is auxiliary switch dilatation schematic diagram of the present invention.
Part is described as follows in attached drawing：1-earthing switch exports connecting rod；2-connecting rod A；3-rocking arm A；4-auxiliary is opened
Close；5-rocking arm B；6-observation window；7-direction board；8-win in succession C.
Embodiment
Embodiment is described below in conjunction with the accompanying drawings.
Rocking arm A and one of auxiliary switch main shaft are direct-connected, and the output connecting rod of connecting plate A and rocking arm A and earthing switch forms
One group of transmission mechanism so that auxiliary switch carries out division signal switching with the movement of earthing switch；Two rocking arm B divide with rocking arm A
Belong to two Different Planes, rocking arm B is direct-connected with two auxiliary switches respectively, and connecting plate B forms one group of transmission mechanism with shaking B, and two shake
Arm B is arranged in parallel so that two auxiliary switches synchronously realize that division signal switches；Direction board is connected with connecting plate B, is carried out with connecting plate B
Pump；Observation window is transparent glass material, is fixed on specific location；When direction board moves to diverse location, it is not
With region and observation window centering, it can observe that the real-time of direction board indicates printed words from observation window.
Earthing switch is from assigning to during conjunction is grounded function, and sequence number 1 exports connecting rod and rotates clockwise, in sequence number 2
Under the drive of connecting rod A, 3 rocking arm A of sequence number is rotated clockwise, and 3 rocking arm A of sequence number and 4 auxiliary switch main shaft of sequence number are direct-connected, band dynamic auxiliary
Switch spindle rotates clockwise；5 rocking arm B of sequence number is rotated clockwise under the promotion of 4 auxiliary switch main axis of sequence number, sequence
Number 5 rocking arm B drive another rocking arm B being arranged in parallel to rotate clockwise by the B that wins in succession of sequence number 8, so as to drive second auxiliary
