If this manual no DL window changes pneumatic mode into, then can realize controlling the switching of shutter, thereby can address the above problem with automatic mode.Yet, " dead ship " state because boats and ships exist in standard, (that is: the state of non-compressed air on the ship), in case meet dead ship state, pneumatic mode can't be opened shutter automatically.And just because of adopted automated manner, the craft that manual work tends to ignore shutter is opened, and when meeting " dead ship " state, almost unavoidable meeting is broken down, and produces dangerous.And " dead ship " state of boats and ships is by chance multiple under the out-of-work state of main generator, adopts this mode to have more serious potential safety hazard.Therefore according to the requirement of standard, the shutter of emergency power generation chamber does not normally allow to adopt this pneumatic shutter.
Summary of the invention
The utility model is intended to overcome above-mentioned defective, even provide a kind ofly when not having compressed air (i.e. " dead ship " state) aboard ship, still can reliably guarantee the emergent opening and closing structure of opening automatically of sending out the shutter of unit room.
The opening and closing structure of the described Emergency Generator shutter of the utility model; Comprise cylinder; Cylinder is up and down two cavity-upper cavities and lower chamber by piston, in the said lower chamber spring is housed, and the two ends of spring are against respectively on the bottom surface of piston bottom surface and cylinder body; Said upper cavity is provided with overhanging tracheae, and electromagnetic valve is installed on the tracheae, can control tracheae and Compressed Gas or atmosphere through electromagnetic valve; The top of piston also connects piston rod, links to each other with the transmission slide fastener of driven shutter blade rotation through piston rod again.
The opening and closing structure of the described Emergency Generator shutter of the utility model; When emergent motor does not start; The solenoid control tracheae communicates with Compressed Gas, and the upper cavity of cylinder charges into Compressed Gas and is high voltage state, and the spring in the cavity is the compression shape; Piston, piston rod and transmission slide fastener are in the position of below, and shutter is closed condition.When the emergency generator emergency start, electromagnetic valve can be controlled tracheae and atmosphere, the upper cavity decompression, and the recoil of spring in the lower chamber promotes to move on the piston, drives transmission slide fastener one the same moving through piston rod, and shutter is opened.Its conducting state through the solenoid control tracheae can realize the operation of the switching of shutter automatically, when emergency generator is promptly launched, can in time open shutter, has avoided opening overtime even forgetting and open the security risk that is caused because of shutter.Simultaneously; Opening of its shutter is that the elastic force through spring promotes under the upper cavity decompression; Even when not having " dead ship " state of Compressed Gas aboard ship, it can normally open shutter equally, avoided under " dead ship " state; The conventional pneumatic shutter danger that shutter can't be opened when emergency generator starts has further improved security performance.
