referring to fig. 1-10, the supporting slide seat assembly 6 includes a circular ring seat 6-1, a U-shaped fixed seat 6-2 and a circular sliding groove 6-3; the circular ring seat 6-1 is fixedly connected inside the four U-shaped fixing seats 6-2, the four U-shaped fixing seats 6-2 are fixedly connected at the outer end of the hollow cylinder 1-1 in a surrounding mode, the middle of the U-shaped fixing seat 6-2 is provided with an annular sliding groove 6-3, the two inner sliding blocks 3-8 are connected in the annular sliding groove 6-3 in a sliding fit mode, the two limiting rods 3-9 are attached to the inner wall of the circular ring seat 6-1, and the two sliding sleeves 3-6 are attached to the outer wall of the circular ring seat 6-1, so that the movement of the inner sliding blocks 3-8 is limited. The circular ring seat 6-1 plays a role in guiding and supporting the whole object blocking piece mounting seat 3.
The specific implementation method nine:
in the following, referring to fig. 1-10, the position-limiting plate 5-6 is located at the left end of the sliding block 7-1, and is used for limiting the position of the sliding block 7-1.
The invention relates to a working principle of a centrifugal fire-fighting smoke exhaust fan, which comprises the following steps: when the device is used, the centrifugal fan component 2 is started to exhaust air, the centrifugal fan component 2 drives the four blocking components 5 and the blocking component mounting seat 3 to synchronously rotate through the blocking regulating component 4, when sundries such as cloth, plastic bags and the like are sucked, the sundries can be blocked by the four blocking components 5 in the inclined state, because the four blocking components 5 are in the inclined state, the sundries can be gathered to the inner wall of the shell component 1 under the rotation of the four blocking components 5 and the horizontal wind force of the working air exhaust of the centrifugal fan component 2, the sundries can be separated from the four blocking components 5, the sundries are prevented from being remained on the four blocking components 5 all the time, the normal air exhaust work of the fan is not influenced, the fan can also be protected, the four blocking components 5 are regulated to be positioned in the same vertical plane through the blocking regulating component 4, the sundries gathered at the outer end can fall on the lower end of the shell component 1 under the action of gravity, the lower end of the shell component 1 is opened, and then sundries can be taken out from the lower end of the shell component 1.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and that various changes, modifications, additions and substitutions which are within the spirit and scope of the present invention and which may be made by those skilled in the art are also within the scope of the present invention.
