A kind of mechanical fire prevention biological shielding automatic closing cover plate, including support 10, transmission mechanism 20, cover plate 30, counterweight
Block 40 and fuse 50；The transmission mechanism 20 is set over the mount 10, and the cover plate 30, balancing weight 40 are arranged at described
On transmission mechanism 20, and it is connected between the cover plate 30 and balancing weight 40 by transmission mechanism 20, the cover plate 30 passes through
Fuse 50 is locked at the upper end of the support 10.
In order to facilitate assembling transmission mechanism 20, cover plate 30, balancing weight 40 and fuse 50, in the present embodiment, the branch
Frame 10 is the vertical structure of cubic framework.
The transmission mechanism 20 includes being arranged on the cover plate rotate gear 21 of the lower end of support 10, is arranged on the upper end of support 10
Balancing weight rotate gear 22, driving chain 23 and cover plate for connecting cover plate rotate gear 21 and balancing weight rotate gear 22
Cover plate cursor 24 that rotate gear 21 is coaxially disposed and the balancing weight cursor being coaxially disposed with balancing weight rotate gear 22
25。
Preferably, in order that obtaining more steady stress when transmission mechanism 20 works, the cover plate rotate gear 21 of the present embodiment
Number be two, correspondingly, the balancing weight rotate gear 22, the number of driving chain 23 also be two.In addition, the lid
Plate cursor 24 includes two cross bars in above two montants of two montants and connection and centre position, and the balancing weight turns
Swing arm 25 also includes two cross bars in above two montants of two montants and connection and centre position.And, it is preferable that institute
The length of cover plate cursor 24 is stated as the length of the balancing weight cursor 25.
The dorsal part of the cover plate 30 is fixed on the outside of the end of cover plate cursor 24, and the balancing weight 40 is fixed on institute
State the outside of the end of balancing weight cursor 25.In the present embodiment, in order to reduce power when cover plate 30 is lifted, while in fuse 50
Melt the and can of back shroud 30 and enough utilize the gravity fall of itself, it is preferable that keep balancing weight 40 relative to balancing weight rotate gear
22 torque is slightly less than torque of the cover plate 30 relative to cover plate rotate gear 21.
Preferably, the cover plate 30 is bolted on the cover plate cursor 24.Also, the cover plate 30 is band
There is the steel barricade of fireprotection layer.In addition, for more convenient lifting cover plate 30, the dorsal part of the cover plate 30 is provided with draw ring 31.
Specifically, the upper end side of support 10 is provided with the first projection 11, and first through hole is provided with the first projection 11；It is described
The end of cover plate cursor 24 is provided with the second projection 26, and the second through hole is provided with the second projection 26；The cover plate 30 with it is described
First through hole is each passed through by fuse 50 between support 10 and the second through hole fixes locking.In addition, in the present embodiment due to
Cover plate cursor 24 includes two montants, and correspondingly, first projection 11, the number of the second projection 26 are preferably two pieces.
In addition, the fuse 50 is low melting point temperature-conditioned metal pin.Because the weight of cover plate itself is bigger, this implementation
In example, it is preferable that the diameter of the low melting point temperature-conditioned metal pin can meet 800kg to 1200kg cover plate in more than 16mm
The intensity requirement of weight locking, chi that in practice can also be according to the weight of cover plate 30 to low melting point temperature-conditioned metal pin in engineering
The appropriate adjustment of little progress row.

Cover plate 30 and support 10 are locked by warm metal pin.
When the condition of a fire occurs for region, air themperature persistently raises, when environment temperature reaches 75 DEG C, the two of locking cover plate 30
Individual low melting point temperature-conditioned metal pin will melt, the thawing time between 60 seconds to 120 seconds, now, work of the cover plate 30 in deadweight
Fallen automatically with lower, and drive balancing weight 40 to rotate by transmission mechanism 20, building channel or hole are fallen under last cover plate 30
Top and the building channel or hole is completely covered, so as to realize fire prevention isolation effect.
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
To original position, and ressemble two low melting point temperature-conditioned metal pins and cover plate 30 and support 10 are locked.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, mechanical fire prevention biological shielding automatic closing cover plate described in the utility model, sets in core
Apply etc. under the conditions of there is radiation, fireproof, independent of motor or crane operation, but the structure for relying on physical characteristics of materials is set
Meter, cover plate are locked at the top of support by fuse, and when the condition of a fire occurs, air themperature rise causes fuse to melt, cover plate
Hole is closed automatically in the presence of deadweight, so as to realize the effect of fire prevention isolation.In addition, mechanical fire prevention of the present utility model
Biological shielding automatic closing cover plate sets balancing weight by the other end in support, so as to operate lid with the external force of very little
Plate, there is very high flexibility.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.
