The part that the cross bar is located at the shift fork axle other end is relative to moving downward.
4. a kind of anti-flooding switchgear as claimed in claim 3, which is characterized in that the mandril is equipped with horizontal for placed shifting fork
The shift fork card slot of the rounded nose of bar, the shift fork card slot are circular trough.
5. a kind of anti-flooding switchgear as described in claim 1, which is characterized in that position switch includes elastic sheet switch electrical part
Divide, elastic slice part and contact head part, the contact head are partly installed in the underface of the elastic slice portions end, the elastic slice
Part extends to the buoy vertical centred position from the transverse slat, touches the contact head timesharing when buoy rises to,
Elastic sheet switch electric part receives signal and is sent in emergency power supply, at this point, emergency power supply opens power supply lifting motor
Power supply moves upwards lifting motor on the rack gear by gear drive, realizes the rising of switchgear entirety；When floating
It floats and is gradually higher than height of water level in uphill process, buoy is separated with the contact head part, and elastic sheet switch electric part receives
Signal is sent to emergency power supply again, and emergency power supply stops power supply, and lifting motor stops working.
6. a kind of anti-flooding switchgear as described in claim 1, which is characterized in that be also provided with and draw on connecting plate described in every group
Air holes.
