The base 14 is a housing in which a circuit board is disposed, and the photoelectric switch 3 is mounted on the circuit board and electrically connected to a circuit on the circuit board.

Referring to fig. 8 in combination with fig. 2 to 7, the driving member 121 has a rotating end, and a fitting head 1211 is disposed on the rotating end, and the fitting head 1211 acts on the moving device 13, that is, the fitting head 1211 acts on the first pushing end 1311 of the first moving rod 131 and the second pushing end 1321 of the second moving rod 132, so as to realize the movement of the moving device 13.

In the present embodiment, the base 14 is fixed on the side plate 11, but if the base 14 is eliminated, the first and second photoelectric switches 31 and 32 may be installed in other manners, for example, the first and second photoelectric switches 31 and 32 are directly installed on the side plate 11 or installed at other reasonable positions of the circuit breaker.

It has been mentioned above that the driving member 121 can be fixed to the rotating shaft 12 in an indirect manner, such as fixing a swing arm to the rotating shaft 12 and fixing the driving member 121 to the swing arm, in addition to being fixed to the rotating shaft 12 directly, and this arrangement can also meet the actual motion requirement, i.e. the requirement that the driving member 121 swings around the rotating shaft 12.

Preferably, a groove is formed on the photoelectric switch 3, and the first light-shielding sheet 1314 is substantially a protrusion protruding out of the sheet shape to cooperate with the photoelectric switch 3, that is, the first light-shielding sheet 1314 protrudes into the groove on the photoelectric switch 3, so that when the first light-shielding sheet 1314 moves, the first light-shielding sheet 1314 shields or releases the shielding of the photoelectric switch 3, thereby realizing the signal conversion of the photoelectric switch 3. Since the second light-shielding sheet 1324 functions in the same way as the first light-shielding sheet 1314, it is not described again.

The working process of the circuit breaker opening and closing in-place signal acquisition device in the embodiment is as follows: in the opening process, as shown in fig. 3 and 4, the driving element 121 swings to a side close to the operating mechanism 1, that is, when the opening is in place, the engaging head 1211 of the driving element 121 contacts the second pushing end 1321, and pushes the second pushing end 1321 to move until swinging to the position where the opening is in place. The second shade 1324 on the second moving bar 132 moves along with the second moving bar 132. When the switch-off in-place position is reached, the second light-shielding sheet 1324 shields the second photoelectric switch 32, and the second photoelectric switch 32 outputs a switch-off in-place position signal. Due to the traction of the elastic member 133 or other elastic members on the second moving rod 132, when the driving member 121 collides with the second pushing end 1321, the second pushing end 1321 is always in contact with the driving member 121, so that the measured brake-opening position signal does not generate deviation.

Similarly, in the closing process, as shown in fig. 5 and 6, when the driving element 121 swings away from the operating mechanism 1, that is, when the closing is to the position, the engaging head 1211 of the driving element 121 contacts the first pushing end 1311, and pushes the first pushing end 1311 to move until the driving element swings to the position where the closing is to the position. The first shutter 1314 on the first moving rod 131 follows the first moving rod 131. When the switch-on position is reached, the first shutter 1314 blocks the first photoelectric switch 31, and the first photoelectric switch 31 outputs a switch-on position signal. Due to the traction of the elastic member 133 or other elastic members on the first moving rod 131, when the driving member 121 collides with the first pushing end 1311, the first pushing end 1311 is always in contact with the driving member 121, so that the measured signal of the switch-on position does not deviate.

The first photoelectric switch 31 and the second photoelectric switch 32 are two independent photoelectric switches, each having a groove in the middle, when the light shielding plate moves into the groove, the light shielding plate triggers the photoelectric switch, the photoelectric switch outputs a low level signal, and when the light shielding plate leaves the groove, the photoelectric switch outputs a high level signal.

In the above embodiments, the situation that the photoelectric switch 3 is turned from conduction to non-conduction when reaching the closing in-place position or the opening in-place position is adopted, that is, after reaching the in-place position, the photoelectric switch outputs a low level signal. Based on the technical content provided by the utility model, the ordinary technical staff in this field can clearly understand, if adopt when combined floodgate position in place or separating brake position in place, photoelectric switch 3 becomes to switch on by not switching on, after targetting in place promptly, photoelectric switch 3 output a high level signal, and this kind of setting belongs to simple transform, should belong to the utility model discloses a protection scope.

To sum up, the technical solution provided by the present invention remedies the defects in the prior art, successfully completes the invention task, and faithfully embodies the technical effects mentioned in the above technical effect column by the applicant.
