Description
Technical field
The utility model is related to fire-fighting equipment field, is specifically related to a kind of fire control smoke exhausting cap.
Background technology
Smoke exhaust fan is applied to ventilation or the high-temperature smoke dischargings such as skyscraper, hypogee and tunnel, drying room.Disappear
The requirement of smoke controlling blower fan can be continuously run under the high temperature conditions, be the indispensable facility of preferable fire-fighting.Smoke on abutment wall
Machine, its air outlet and ft connection, the air inlet of traditional abutment wall smoke exhaust fan are easily accessible rainwater, cause inside smoke exhaust fan
Damage by Short Circuit, and because insect is easily accessible blower interior, cause impeller operation to have some setbacks, electrical short-circuit is caused, therefore, generally existing
Smoke exhaust fan air outlet installs rain cover additional, but rain cover can increase resistance, reduces air output, influences smoke discharging effect.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of fire control smoke exhausting cap, effectively can prevent rainwater from entering inlet air
Inside machine, it is to avoid cause electrical short-circuit to damage, rainhat falls automatically during smoke evacuation, increases capacity, reduces resistance.
In order to solve the above technical problems, the technical solution adopted in the utility model is as follows：A kind of fire control smoke exhausting cap, its feature
It is：Including body, rain cover and switching device, air inlet and gas outlet, the rain cover and sheet are offered on the body
The gas outlet connection of body, the rain cover is provided with downward opening exhaust outlet, and bottom and the body of the rain cover are hinged, institute
State pedestal, the fixture block above pedestal, thermoinduction glass marble and connecting rope that switching device includes being fixed on rain cover, institute
State inner body wall and be positioned over provided with blind hole, the fixture block is placed in placement blind hole, the thermoinduction glass marble upper and lower ends difference
Abut pedestal and fixture block, the two ends difference connecting rain-proof cover and fixture block of the connecting rope.
Further, the pedestal is provided with the tapped through hole and screw cooperated, and tapped through hole is with placing in blind hole
Lower correspondence, the bottom of the thermoinduction glass marble abuts screw head.
Further, it is in spherical in needle-like, bottom at the top of the thermoinduction glass marble.
Further, the fixture block is provided with shrinkage pool, the top insertion shrinkage pool of the thermoinduction glass marble.
Further, the rain cover is hemispherical, and exhaust outlet is located at rain cover the latter half.
Seen from the above description, the fire control smoke exhausting cap that the utility model is provided effectively can prevent rainwater from entering smoke discharging pipe
It is internal, it is to avoid to cause motor and electrical short-circuit in smoke discharging pipe to damage, rainhat falls automatically during smoke evacuation, increase row
Tolerance, reduces resistance, improves flue gas velocity.
Brief description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model fire control smoke exhausting cap.
Fig. 2 is the schematic cross-sectional view of the use state of the utility model fire control smoke exhausting cap.
Fig. 3 is the structural representation of the use state of the utility model fire control smoke exhausting cap.
Embodiment
Below by way of embodiment, the utility model will be further described.
As depicted in figs. 1 and 2, fire control smoke exhausting cap described in the utility model, including body 1, rain cover 2 and switch dress
Put, air inlet and gas outlet are offered on body 1, rain cover 2 is connected with the gas outlet of body 1, and rain cover 2 is hemispherical, prevent
The latter half of canopy 2 is provided with downward opening exhaust outlet 21, and bottom and the body 1 of rain cover 2 are hinged, and switching device includes fixing
In the pedestal 31 on rain cover 2, fixture block 32, thermoinduction glass marble 33 and connecting rope 34 positioned at the top of pedestal 31, the inwall of body 1
Provided with the placement blind hole 11 that Open Side Down, under the support of thermoinduction glass marble 33, the insertion of fixture block 32 is placed in blind hole 11, connecting rope
34 two ends difference connecting rain-proof cover 2 and fixture block 32, the upper and lower ends of thermoinduction glass marble 33 abut pedestal 31 and fixture block 32 respectively,
Pedestal 31 is provided with the tapped through hole and screw 311 cooperated, and placement blind hole 11 is corresponding with above and below tapped through hole, thermoinduction
The bottom of glass marble 33 abuts the top of screw 311, and because the insertion of fixture block 32 is placed in blind hole 11, rain cover 2 is led in connecting rope 34
Leave behind the gas outlet of laminating body 1, the top of thermoinduction glass marble 33 is in needle-like, bottom in spherical, and thermoinduction glass marble 33 is built-in
There is expansion working solution, explosion temperature is 70-80 degrees Celsius, fixture block 32 is provided with shrinkage pool, the top of thermoinduction glass marble 33 is embedded in
In shrinkage pool.
As shown in Figures 2 and 3, this fire control smoke exhausting cap is placed at the air outlet of the wind pipe of smoke exhaust fan,
Rain cover 2 is located on the outside of metope, and under non-State of alarm, smoke exhaust fan is used as draught fan, and gas is via body 1
Outdoor is discharged to rain cover 2；When running into fire, smoke exhaust fan extracts high-temperature flue gas out outdoor, and the temperature of general flue gas can
The explosion of thermoinduction glass marble 33 is made with the working solution expansion being up in 200 degrees Celsius, thermoinduction glass marble 33, fixture block 32 falls,
Now the connecting rope 34 on rain cover 2 loses traction force, in the case where deadweight and wind-force drive, downwardly turns over and departs from going out for body 1
Gas port, thus wind resistance can be reduced out, increase fume emission efficiency.
Some embodiments of the present utility model are above are only, but design concept of the present utility model is not limited to
This, all changes for carrying out unsubstantiality to the utility model using this design all should belong to infringement the utility model protection domain
Behavior.
