Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, the present embodiment provides a smoke-proof reverse flow device, which includes an annular base frame 1, a bracket 2, a rain and snow cover 3, a balancing pole 4, a wind-force guide rudder 5, and a wind deflector 6.

Annular base frame 1 includes an annular circle and fixes the cross skeleton in the annular circle, four extreme points of cross skeleton all with annular circle fixed connection, preferably welded connection. The center of the cross-shaped framework is positioned at the position of the circle center of the annular ring. In use, the annular base frame 1 is fixedly mounted on top of a flue.

The bottom of support 2 with annular base frame fixed connection, the top with rain and snow keeps off lid 3 fixed connection, specifically can carry out fixed connection through the screw. For convenience in installation, the support 2 is a stepped shaft, the bottom of the stepped shaft is vertically fixed at the center of the cross-shaped framework, the top of the stepped shaft is in threaded connection with the rain and snow cover 3, and the diameter of the bottom of the stepped shaft is larger than that of the top of the stepped shaft.

The balance bar 4 is provided with a through hole, the support 2 penetrates through the through hole, and the balance bar 4 rotates around the support 2. The through hole on the balancing pole 4 is matched with the stepped shaft, so that the wind shield 6 can rotate under the action of small ground wind, and the wind shielding reliability of the device is improved.

The wind power steering rudder 5 is fixedly arranged at one end of the balance rod 4, the wind shield 6 is fixedly arranged at the other end of the balance rod 2 along the vertical direction, the wind shield 6 is arranged to be an arc-shaped baffle, the arc-shaped baffle is concentric with the annular ring, and the bottom of the arc-shaped baffle extends to the annular ring. In order to further improve the effect of the smoke and dust refluence of smoke and dust prevention inverter avoids wind to follow the bottom of curved deep bead 6 blows over, influences the effect that blocks of deep bead 6 to and avoid influencing the guide effect of wind-force steering rudder because deep bead 6 sets up too high, will the base of deep bead 6 sets up to be less than the bottom surface of annular base frame 1, wind-force steering rudder 5 is higher than the 6 topside of deep bead is preferred to be with the top of deep bead 6 with balancing pole 4 carries out fixed connection. Wherein the wind deflector 6, the wind-guiding rudder 5 and the balancing bar 4 are preferably connected by welding.

The working principle of the smoke-proof reverse flow device is as follows: when wind blows along the direction parallel to the balancing rod 4, the wind shield is perpendicular to the wind direction, the wind is blocked by the wind shield 6, and the smoke dust is prevented from flowing backwards by wind force; when wind blows along the direction vertical to the wind balance bar 4, the direction of the wind is indicated by F in fig. 1, the direction of the wind is indicated by W, the wind pushes the wind-guiding rudder 5 and the balance bar 4 to rotate, and when the balance bar 4 rotates to be consistent with the wind direction, the wind is blocked out by the wind deflector 6 vertical to the wind direction; when wind blows along a certain angle inclined to the balance bar 4, the wind can be decomposed into horizontal wind parallel to the balance bar 4 and vertical wind perpendicular to the balance bar 4, the wind perpendicular to the balance bar 4 pushes the wind guide rudder 5 and the balance bar 4 to rotate, and when the balance bar 4 rotates to be consistent with the wind direction, the wind deflector 6 blocks the wind out perpendicular to the wind direction. Therefore the utility model provides a smoke protection and dust inverter passes through the effect of wind-force direction rudder 5 and the rotation of balancing pole 4 can make the direction of balancing pole 4 and wind remain parallel throughout to the purpose that the realization kept out the wind. Meanwhile, the rain and snow blocking cover 3 is arranged at the top of the bracket 5, so that smoke in the flue is not affected by external climate change, and the smoke exhaust channel of the farmhouse range is smooth.

The utility model provides a smoke and dust protection current inverter through fixing annular base frame 1 at the top of flue, through the setting of balancing pole 4 and fix respectively the wind-force direction rudder 5 and the setting of deep bead 6 at 4 both ends of balancing pole, balancing pole 4 can rotate around the support, and rotate in a flexible way to make balancing pole 4 remain unanimous with the wind direction all the time, wind-force blocks the outside at deep bead 6 all the time, thereby realizes avoiding the problem of the smoke and dust refluence that the wind arouses.

The above description of the present invention does not limit the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the scope of the claims of the present invention.
