The elliptic smoke exhaust pipeline is adopted, the attitude angle of the elliptic smoke exhaust pipeline can be adjusted through the gear mechanism through the gear transmission system, so that the short axis of the elliptic smoke exhaust pipeline faces the wind, the adverse effect of the strong wind weather on the smoke exhaust pipeline is reduced as much as possible, and the adverse effects of collapse and the like caused by failure of the smoke exhaust pipeline due to insufficient strength or fatigue are further reduced.
Description
Technical Field
The utility model relates to a smoke exhaust system for a large building in a polar region, in particular to an elliptical smoke exhaust pipeline with a rotatable attitude angle.
Background
In a large building smoke exhaust system in an polar region, a smoke exhaust pipeline at the top of a building protrudes out of the surface of the building, and the smoke exhaust pipeline can fail due to insufficient strength or fatigue even collapse and other adverse effects under the long-term influence of strong wind in the polar region. At present, the section of a smoke exhaust pipeline is circular or rectangular, the wind load of the smoke exhaust pipeline with the rectangular section under the strong wind condition is relatively large and is not suitable for polar regions, the wind load of the smoke exhaust pipeline with the circular section under the strong wind condition is relatively small, but the wind load of the smoke exhaust pipeline with the circular section under various wind directions is basically the same, and the influence on the smoke exhaust pipeline under the strong wind weather of the polar regions cannot be reduced to the maximum extent.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides an oval smoke exhaust duct with an adjustable posture. The device can ensure that the elliptical smoke exhaust pipeline adjusts the attitude angle through the gear mechanism, and the short shaft faces the wind, thereby reducing the adverse effect of the windy weather of the polar region on the smoke exhaust pipeline as much as possible.
In order to realize the purpose, the utility model adopts the technical scheme that:
an oval smoke exhaust pipeline with rotatable attitude angles comprises a driven gear, wherein the lower part of the driven gear is inserted into a mounting hole of a building roof, a shaft sleeve is sleeved at the end part of the mounting hole of the building roof, the shaft sleeve is in clearance fit with the bottom wall of the building roof, four driving gears are uniformly distributed along the circumferential direction of the driven gear and are meshed with the driven gear, gear shafts of the four driving gears are respectively fixed on the building roof through gear bearings, the gear shaft of one driving gear is fixedly connected with a rotating shaft of a servo motor arranged along the vertical direction, the rest three driving gears are used as auxiliary driving wheels, the servo motor is fixed on the inner wall of the building roof, a wind direction sensor and a wind speed sensor are respectively arranged at the top of the oval smoke exhaust pipeline, and the wind direction sensor and the wind speed sensor are respectively connected with a signal input end of an industrial personal computer through control lines, and the signal output end of the industrial personal computer is connected with the servo motor through a control line.
The utility model is applied to a smoke exhaust system of a large building in an arctic region, and automatically adjusts the posture of the elliptical pipeline by detecting the wind speed and the wind direction of the region, so that the short shaft is in the windward direction, and the adverse effect of the arctic gale weather on the smoke exhaust pipeline is reduced as much as possible.

Detailed Description
The utility model is described in detail below with reference to the figures and specific embodiments.
As shown in the attached drawing, an elliptical smoke exhaust pipeline with rotatable attitude angle comprises a driven gear 2 welded on the lower part of the outer wall of an elliptical smoke exhaust pipeline 1 in an annular sleeve manner, the lower part of the driven gear 2 is inserted into a mounting hole of a building roof 8, a rotating bearing is preferably arranged in the mounting hole, the lower part of the driven gear 2 penetrates through the rotating bearing, a shaft sleeve 10 is sleeved on the end part of the mounting hole penetrating through the building roof 8, the shaft sleeve 10 is in clearance fit with the bottom wall of the building roof 8, four driving gears 3 uniformly distributed along the circumferential direction of the driven gear 2 are meshed with the driven gear 2, gear shafts of the four driving gears 3 are respectively fixed on the building roof 8 through gear bearings 11, a gear shaft of one driving gear 3 is fixedly connected with a rotating shaft of a servo motor 4 arranged along the vertical direction, and the other three driving gears 3 are used as auxiliary driving wheels, servo motor 4 fix on the inner wall of building roof 8, preferably, be provided with a apron 5 above each driving gear 3, the one end of apron 5 pass through the bolt fastening on the outer wall of building roof 8, cover the top of driving gear 3.
A wind direction sensor 6 and a wind speed sensor 7 are respectively arranged on the top of the oval smoke exhaust pipe 1. The wind direction sensor 6 and the wind speed sensor 7 are respectively connected with a signal input end of an industrial personal computer 9 through control lines, and a signal output end of the industrial personal computer 9 is connected with the servo motor 4 through the control lines.
The working principle of the device is as follows:
when the regional wind speed and the wind direction change, the wind direction sensor 6 and the wind speed sensor 7 output signals to the control industrial personal computer 9. After the industrial personal computer 9 receives the signal, control servo motor 4 and pass through motor rotation axis and drive driving gear 3 and rotate around self axis, and driving gear 3 drives driven gear 2 through gear engagement and rotates, and driven gear 2 is rotatory in-process and drives three auxiliary drive wheel and rotate, and driven gear 2 is rotatory simultaneously and drives the rotation of the oval exhaust pipe 1 that welds on it, makes the minor axis of oval exhaust pipe 1 all the time windward, has realized the rotation of oval exhaust pipe gesture angle promptly.
