Preferably, the latching electromagnet DST includes magnet exciting coil and latching electromagnet locking bar.
Preferably, the side of the lower valve mechanism and upper valve mechanism is provided with safety warning or safety alarming and identifying.
A kind of present invention valve mechanism locking system of design, maintenance position can be drawn out in switching on/off handcart, when bus or When circuit has electricity, the corresponding valve mechanism of automatic locking, with ensure staff when switch gear room works cannot artificially or due to Touch unlatching valve baffle plate by mistake, it is ensured that the safety and reliability of work, so as to improve the essential safety of switch cubicle, by electrically, Electromagnetism and mechanical latching function, effectively prevent artificial or open valve baffle plate generation accident of human electric shock due to touching by mistake.
Brief description of the drawings
Fig. 1 is a kind of structural representation of valve mechanism locking system proposed by the present invention;
Fig. 2 is a kind of logical circuitry of valve mechanism locking system proposed by the present invention.
In figure:1 handcart track, 2 times valve mechanisms, valve mechanism on 3,4 times valve mechanism locking holes, valve mechanism on 5 Locking hole, 6 roller switches.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.
Reference picture 1-2, a kind of valve mechanism locking system, including handcart track 1, lower valve mechanism 2, upper valve mechanism 3, Lower valve mechanism locking hole 4, upper valve mechanism locking hole 5 and roller switch 6, the side of the handcart track 1 is provided with roller Switch 6, the side of the handcart track 1 is provided with lower valve mechanism 2 and upper valve mechanism 3, and lower valve mechanism 2 is located at upper work The top of door mechanism 3, the upper valve mechanism 3 is provided with valve mechanism locking hole 5, and the lower valve mechanism 2 is provided with down Locking electricity is mounted in the hole of valve mechanism locking hole 4, the upper valve mechanism locking hole 5 and lower valve mechanism locking hole 4 Magnet DST, the rolling switch 6 is provided with rolling switch auxiliary contact H1, the other end of the rolling switch auxiliary contact H1 It is electrically connected with the other end of bus and circuit charged display device H2, the bus and circuit charged display device H2 auxiliary contacts Being electrically connected with latching electromagnet DST, the latching electromagnet DST includes magnet exciting coil and latching electromagnet locking bar, the lower work The side of door mechanism 2 and upper valve mechanism 3 is provided with safety warning or safety alarming and identifying.
In the present invention, one latching electromagnet DST is respectively installed in the outside of upper and lower valve mechanism, is passed using its locking bar and valve The cooperation of motivation structure, realizes the mechanical locking of valve mechanism, and the track side surfaces in switch gear room install a roller with auxiliary contact Switch 6, the chassis vehicle with wheelbarrow switch coordinates, and controls cut-offfing for its auxiliary contact, electrical control:Bus and circuit is powered aobvious The normally opened auxiliary contact of showing device H2 is respectively connected to corresponding latching electromagnet wire loop, while being connect in corresponding control loop Enter the normally closed auxiliary contact of roller switch 6, to control the break-make of latching electromagnet coil DST, in order to not influence switching on/off handcart Normal operating and prevent latching electromagnet coil it is long-term it is powered burn out, when wheelbarrow switch is exited to maintenance position, using roller The normally closed auxiliary contact of switch 6 connects electric loop, and locking valve mechanism, when wheelbarrow switch is pushed into testing position, is utilized The normally closed auxiliary contact of roller switch disconnects electric loop, releases the locking to valve mechanism.Set at lockable mechanism obvious Safety warning, alarming sign, on the upper and lower valve baffle plate in switch gear room spraying " bus is powered, forbid open!", " circuit is powered, Forbid opening!" and " powered " and " forbidding " icon, improve security.
