Abstract
The present invention relates to an automatic actuating mechanism for a fire-extinguishing and smoke-exhausting valve, which is arranged in a smoke-exhausting and fire-extinguishing valve body of a ventilation system for high buildings, large ships, nuclear power plants, etc. in order to turn on and off a smoke-exhausting and fire-extinguishing valve body. A transmission mechanism is fixed to an output gear having a circular arc through hole groove and an output movable wheel having a clearance fit surface fixed with a movable wheel pin via an output shaft, and the movable wheel pin on the output movable wheel is inserted in the circular arc through hole groove of the output gear to form a sliding fit with the output gear. The output gear is engaged with a gear on a gearset which is engaged with a gear on a motor shaft, and the output movable wheel is engaged with a segment gear fixed to a main shaft. The automatic actuating mechanism using full gear transmission solves the problem that the main shaft can not bounce back in an operating and restoring process, all gears can not be tightly engaged, and automatic actuating mechanism invention having the advantages of little resistance of transmission and restoration, rapid action, short restoring time, stable performance, safe and reliable use, compact structure, less parts, large direct driving torque force and favorable sealing property can be particularly used for ships having the requirements of water prevention.
Description
Technical field
The present invention relates to a kind of being installed in the smoke evacuation of ventilating systems such as skyscraper, large ship, nuclear power station, the valve body of preventing fires, be used for smoke evacuation, fire prevention valve body are opened, closed the device of use, fire and smoke exhaust valve fully-automatic actuating mechanism.
Background technology
The patent No. 00246855.7 " the fire resisting damper executing agency of automatically discharging fume " is though the executing agency that also provides a kind of energy full automatic working exhaust opening to open and close, but it has adopted the transmission mechanism of rod-pulling type, by upper gear of motor shaft by the engagement that cogs of gear train and controller shaft, and the axle on the gear with pull bar by being connected with rotating shaft that main shaft is gone up in flakes, driving main shaft again rotates, the part of intermediate link is more, volume is bigger, there are geneogenous defective and weak point, as the valve body frequent starting and starting torque is very big, will make pull bar, fatiguability damages in flakes, causes distortion, even fracture, especially be installed in the executing agency on the large ship, boats and ships navigate by water in wind and waves, and suffered vibrations are bigger, there is unsafe hidden danger in the easier stressed fracture of pull bar, because of adopting the rod-pulling type structure, need pull bar is installed on base plate in addition, be difficult to hermetically sealed, so this mechanism also can't use having on the boats and ships of waterproof requirement, its scope of application is restricted has certain limitation.
Summary of the invention
Technical problem to be solved by this invention is: a kind of fire and smoke exhaust fully-automatic actuating mechanism is provided, be full-closed structure, and compact conformation, volume are little, good seal performance, the scope of application are wide, and have that torsion is big, actuation time weak point, stable performance, easy to use and reliable characteristics.
The present invention addresses the above problem the technical scheme that is adopted: fire and smoke exhaust valve fully-automatic actuating mechanism is by the heat detector in the case, band pushes away circle, the push button shaft of stage clip, be fixed on the installing plate rocker axle and be with roller, the rocker of fine motion dead man respectively be fixed on the fork axle, fork on the electromagnet and the cam that is fixed on the main shaft cooperate, be connected with handle on the main shaft, disc spring, be fixed with miniature cam on the output shaft, and electric elements, microswitch is fixed on the installing plate, with lead be connected with terminal box and upper gear of motor shaft through transmission mechanism be connected with main shaft constitute, also be fixed with base plate on the described installing plate, described transmission mechanism is by fixing on the output shaft, on the output gear of circular arc through-hole groove is arranged and is fixed with the output driving wheel of driving wheel pin above the matched in clearance, and in the circular arc through-hole groove on the insertion of the driving wheel pin on the output driving wheel output gear, be slidingly matched with it, output gear and with upper gear of motor shaft meshed gears group engagement, the output driving wheel constitutes with the sector gear engagement that is fixed on the main shaft.
Compared with prior art, the invention has the advantages that: because of this transmission mechanism all adopts gear drive, intermediate links such as pull bar transmission have been cancelled, directly driving main shaft by the gears engaged sector gear rotates, and the problem that main shaft can't resilience when having solved the all-gear drive mechanism action, so its more compact structure, part is few, volume is little, because of directly so transmission torsion is big, reset, actuation time is short and stable performance, and overcome the birth defects that pull bar is yielding, rupture, eliminated hidden danger.Adopted totally enclosed structure, good seal performance can be installed and used having on the boats and ships of waterproof requirement, the scope of application is wide, has adopted floating-point formula mounting means again, can regulate automatically among a small circle, remedy because of installation brings the influence of moving to carrying out, thus safe in utilization, reliable.
