Description
Technical field
The invention belongs to fire-fighting equipment technical field, particularly a kind of Full-automatic fireproof door closer.
Background technology
Current structural fire protection fire escape labeled door, major function plays the isolation condition of a fire and personnel escape's effect.Labeled door is opened towards passageway for fire apparatus, and with automatically replying function, people is easy to from residential community or commercial area just can run to passageway for fire apparatus, and door can be closed automatically, stops pyrotechnics to enter, for escape personnel wins more chances for survival.And the emergent control when daily management of labeled door and breaking out of fire has just become the problem of necessary solution.Current main following technology is main:
One, electromagnetism door-inhale: what this equipment used is electromagnetic principle, be the new product of ability Development and Production recent years, the electromagnet be made up of electromagnetic coil and suction disc form.When pushing, door-inhale is lived location by electromagnetism door-inhale automatically, and without the need to manually, during fire, power-off release, closes under fireproof door closer effect automatically.Cut off power supply during breaking out of fire to realize automatically closing.But this product no signal feedback function, directly uses fire-fighting loop power supply, take fire-fighting power supply capacity, and is in large power-consumption standby state all the year round, because function too simply there is no failure protection function, once coil occurs that short trouble also can cause hidden fire-fighting danger.
Two, magnetictrip: this is the primary product of producing the earliest, is made up of main body and snap close.At ordinary times without the need to electricity consumption, open the door when locating and want manually electromagnetic releaser to be inserted in dropout, during fire, power transmission release, closes under the effect of labeled door hydraulic door-closer automatically.Labeled door is closed under common door closer effect.Automatically reseting when reusing, need hand-reset.Because its internal mechanical structure is many, the yielding or jam such as plectrum, connecting rod, snap close and quality problems often occur, and also power transmission is closed the door and is not met fire protection rule, gradually by market.
Three, electromagnetic door closer: this device is also the electric-controlled mechanical door closer comparatively early occurred, is made up of main body and connecting rod.Its inside is electromagnetic valve and brute spring, Compress Spring when pushing by electromagnetic valve locking, during power transmission, electromagnetic valve release is closed by the rebounce power of spring, does not have pooling feature, can not speed governing, impact and can rebound behind the door, therefore can not be called door closer, also not meet GA93-2004 " fireproof door closer " requirement, also fire protection cannot be passed through by GA93-2004 " fireproof door closer " at present, and fault rate is high, easily hurt sb.'s feelings during installation, easily thrust at closing time.
Four, common door closer: be applied to movable labeled door, is made up of at any time to push main body and connecting rod and all will cuts out at once, and routine use is frequent, and access times are limited, more can not link with fire fighting system without feedback signal.
In sum, current labeled door controls product and is still in the junior stage, function is perfect not to the utmost, always there are more such-and-such problems, and mostly need to take fire-fighting power supply capacity, the fault of any node all likely causes overcurrent or the short circuit of fire-fighting power supply, whole fire fighting system seriously can be caused to paralyse, form huge hidden danger to the prevention and control of the condition of a fire.Not a kind of product can not take into account all problems, and current product is also just in order to cater to fire codes and forced application, and reliability is not high is greatest problem place.
Summary of the invention
The object of the invention is to provide a kind of safe, practical, highly reliable, full automatic fire-proof door closer, meets the need of market with this.This kind of fire-proof door closer with MPC fire-fighting controller for signal processing apparatus, with fire-proof door closer unit for executing agency, by cable, the same smoke detector of MPC fire-fighting controller, alarm switch and fire-proof door closer unit are connected, wireless transmission and receiving device is provided with in MPC fire-fighting controller, effective interlock of same Fire Net can be realized, and can with allly on the market often opening, normally closed and free labeled door is compatible, the fire fighting system that can be applicable to various large, medium and small type generally uses.
Accompanying drawing 1 is this invention mounting structure schematic diagram, as seen from the figure, the Full-automatic fireproof door closer of this invention is primarily of MPC fire-fighting controller (1), fire-proof door closer unit (2), pivoted arm (3) and relevant cables composition, wherein MPC fire-fighting controller is by the same smoke detector of distinct interface, alarm switch and fire-proof door closer unit are connected, during installation, fire-proof door closer unit (2) is fixed on the upper door frame (4) of labeled door (5), one end of pivoted arm (3) is connected with fire-proof door closer unit (2) and controls domination by it, the other end is then fixed on labeled door (5).
Designed fire-proof door closer unit (2) as shown in Figure 2, primarily of reduction box (6), output shaft (7), bevel gear (8), casing (9), the planetary reducing motor (10) of electric brush type and installing plate (11) composition, wherein the component such as planetary reducing motor (10) are installed in casing (9), planetary reducing motor (10) is connected on output shaft (7) by bevel gear (8), after the square spigot output reducer casing (6) of output shaft (7), with connecting together with the pivoted arm (3) with square hole, the other end of pivoted arm (3) is connected by screw on labeled door (5) door body, whole fire-proof door closer unit (2) is arranged on the upper door frame (4) of labeled door (5) by the installing plate (11) of two ends symmetry.Labeled door (5) door body as shown in Figure 3, is in opening at ordinary times, when the central processing unit in MPC fire-fighting controller (1) detects that the fire alarm rear drive planetary reducing motor (10) of extraneous input drives output shaft (7) to rotate, drive pivoted arm (3) that door is closed to position as shown in Figure 4, automatically stop after the position sensor that after closedown puts in place, planetary reducing motor (10) is inner detects door-closing in-place signal, fire alarm is removed rear planetary reducing motor and is driven output shaft (7), by pivoted arm (3), labeled door (5) door body is opened 90 ° when labeled door unlatching puts in place, the position sensor of planetary reducing motor inside detects that enabling puts in place after signal and rotates and will automatically stop.
During work, after MPC fire-fighting controller (1) receives the warning message sent by smoke detector, alarm switch or wireless network, instruction is sent to fire-proof door closer unit (2) by cable, make it start and drive pivoted arm (3) to tighten up, labeled door (5) is pulled to operate and labeled door closedown the most at last, thus reaching fire prevention isolation, mitigation keeps away the object of cigarette.
