Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Example 1

Referring to fig. 1 and 2, a fire engineering is with auxiliary device that discharges fume, includes smoke exhaust pipe 1, still includes:

the rotary smoke guide mechanism is arranged on the smoke exhaust pipeline 1 and comprises a smoke guide pipe 2 and a plurality of first rotary sealing rings 3, the smoke guide pipe 2 is sleeved on the smoke exhaust pipeline 1, the smoke guide pipe 2 is of an L-shaped structure, rainwater can be prevented from entering the smoke exhaust pipeline 1 from the smoke guide pipe 2 by utilizing the smoke guide pipe 2 of the L-shaped structure, drying in the smoke exhaust pipeline 1 is further ensured, the situation that water is accumulated in the smoke exhaust pipeline 1 is avoided, and the first rotary sealing rings 3 are arranged on the smoke guide pipe 2 and the smoke exhaust pipeline 1 together; a plurality of first rotary seal ring 3 can enough be with leading the tobacco pipe 2 spacing on exhaust pipe 1, when guaranteeing that the leakproofness is good between leading tobacco pipe 2 and the exhaust pipe 1, can also not influence and lead the rotation of tobacco pipe 2 on exhaust pipe 1.

The driving mechanism is fixed on the smoke guide pipe 2. When the driving mechanism drives the smoke guide pipe 2 to rotate, when the smoke discharge direction of the smoke guide pipe 2 rotates to the designated direction, the driving mechanism stops working, and the driving mechanism has a self-locking function, so that the smoke discharge direction of the smoke guide pipe 2 is prevented from changing again under the action of wind power.

This fire engineering is with auxiliary device that discharges fume when using, actuating mechanism fixes at the roof, when needs change the orientation of discharging fume, actuating mechanism starts, under actuating mechanism's drive, again because discharge flue 1 and lead and be equipped with a plurality of first rotary seal 3 between tobacco pipe 2 jointly, under the assistance of a plurality of first rotary seal 3, can enough ensure that discharge flue 1 and the junction of leading tobacco pipe 2 can not have revealing of smog, can also not influence actuating mechanism and drive and lead tobacco pipe 2 and rotate on discharge flue 1, and then can change the orientation of discharging fume on leading tobacco pipe 2, and then can avoid leading the condition that the orientation of discharging fume on tobacco pipe 2 is just facing wind.

Example 2

On the basis of embodiment 1, although the smoke guide pipe 2 is sleeved on the smoke exhaust pipe 1, generally, rainwater does not enter the smoke guide pipe 2 to corrode the first rotary sealing ring 3, but when heavy rainstorm occurs, rainwater cannot enter the smoke guide pipe 2 to corrode the first rotary sealing ring 3, and the service life of the first rotary sealing ring 3 is reduced, referring to fig. 1-3, the utility model is different from embodiment 1 in that the utility model further comprises a waterproof mechanism, and the waterproof mechanism is fixed on the smoke guide pipe 2. The waterproof mechanism comprises a first protective cover 8, a reinforcing component and a third protective cover 13, the first protective cover 8 and the third protective cover 13 are sleeved and fixed on the smoke guide pipe 2, and the reinforcing component is fixed on the first protective cover 8. One end of the first protective cover 8, which is far away from the smoke guide pipe 2, is sleeved on the smoke exhaust pipeline 1, and the gap between the smoke exhaust pipeline 1 and the first protective cover 8 is very small, but the smoke exhaust pipeline 1 cannot influence the rotation of the first protective cover 8 along with the smoke guide pipe 2.

Example 3

On the basis of embodiment 2, since the first protection cover 8 is only fixed on the smoke guide pipe 2, the firmness degree between the first protection cover 8 and the smoke guide pipe 2 is low, referring to fig. 1-3, another preferred embodiment of the present invention is different from embodiment 1 in that the reinforcing assembly comprises a plurality of reinforcing frames 9 and bearings 10, the bearings 10 are sleeved and fixed on the smoke exhaust pipe 1, one end of each reinforcing frame 9 is fixed on the bearing 10 at equal intervals, and the other end of each reinforcing frame 9 is fixed on the first protection cover 8 at equal intervals. The arrangement of the bearing 10 can not only enable the reinforcing frames 9 to rotate along with the smoke guide pipe 2, but also prevent the smoke exhaust pipeline 1 from influencing the rotation of the reinforcing frames 9.

Example 4

On the basis of the embodiment 1, referring to fig. 1 and 2, as another preferred embodiment of the present invention, the difference from the embodiment 1 is that the driving mechanism includes a motor 7, a rotating shaft 6, a first gear 4 and a second gear 5, the motor 7 has a self-locking function, and the motor 7 is fixed on the roof of one side of the smoke exhaust pipeline 1, one end of the rotating shaft 6 is fixed on the top end of the output shaft of the motor 7, the other end is fixed on the second gear 5, the first gear 4 is fixed on the smoke guide pipe 2 inside the third protecting cover 13 in a sleeving manner, and the first gear 4 and the second gear 5 are engaged with each other; the third prevention cover 13 is used for shielding the first gear 4 and the second gear 5 from rainwater, so that the first gear 4 and the second gear 5 are prevented from being corroded by rainwater;

because motor 7 has one section distance apart from second gear 5, third protection casing 13 can not be fine shelters from the rainwater for motor 7, the cover is equipped with second protection casing 11 on the axis of rotation 6, be equipped with second rotary seal 12 between second protection casing 11 and the axis of rotation 6 jointly, 11 sealed roofs of fixing in exhaust pipe 1 one side of second protection casing, and second protection casing 11 covers motor 7 inside, second rotary seal 12's setting, can enough let motor 7 normal drive axis of rotation 6 rotate, can also ensure the leakproofness between axis of rotation 6 and the second protection casing 11.

The motor 7 drives the second gear 5 to rotate through the rotating shaft 6, the second gear 5 drives the first gear 4 to rotate, the first gear 4 drives the smoke guide pipe 2 to rotate on the smoke exhaust pipeline 1, the orientation of a smoke exhaust port of the smoke guide pipe 2 can be changed, and the motor 7 is controlled by the remote control switch to ensure that the motor 7 is normally opened in case of fire.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
