The operation principle of the fire equipment for automatically controlling closing of the explanation present invention below：
In normal conditions, cover plate 30 is in an open position, i.e., will by electric pushrod 50 perpendicular to 90 ° of ground of installation
Cover plate 30 is locked with support 10.
When the condition of a fire occurs for region, air themperature rise, when environment temperature reaches a certain temperature value, temperature sensor 51 will
Detect that the induced signal of the temperature value is sent to controller 52, now controller 52 is according to the actuated signal control electric pushrod
The body of rod at 50 both ends, which is shunk back, to be come, so that cover plate 30 falls automatically in the presence of deadweight, and passes through the band of transmission mechanism 20
Dynamic balancing weight 40 rotates, and falls on the top of building channel or hole under last cover plate 30 and the building channel or hole is completely covered
Hole, so as to realize the effect of fire prevention isolation.
After having handled the condition of a fire and having ensured safety, technical staff is lifted cover plate 30 by the draw ring 31 on cover plate 30 again
Control electric pushrod 50 that cover plate 30 and support 10 are locked to original position, and again through controller 52.Wherein, by
Balancing weight 40 is provided with the opposite side in support 10, and balancing weight 40 is smaller relative to the torque of balancing weight rotate gear 22
Torque in cover plate 30 relative to cover plate rotate gear 21, therefore it may only be necessary to which the external force of very little can operate the lifting of cover plate 10.
Compared with prior art, the fire equipment of the present invention for automatically controlling closing, when the condition of a fire occurs, Air Temperature
Degree rise, detect the temperature of environment by temperature sensor and send induced signal to controller, controller and believed according to sensing
Number the flexible of electric pushrod is controlled, so as to control the whereabouts of cover plate to close hole, realize the effect of fire prevention isolation.In addition, this
The fire equipment for automatically controlling closing of invention sets balancing weight by the other end in support, so as to use the external force of very little
To lift cover plate, there is very high flexibility.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Can not therefore it be construed as limiting the scope of the patent.It should be pointed out that come for one of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.
