The specific embodiment
below in conjunction with the specific embodiment, be elaborated.
embodiment mono-, as Fig. 1, Fig. 3, shown in Fig. 7, anti-downdraft chimney hood, comprise turning shape cylindrical shell 1, shape cylindrical shell 1 below, turning is for entering mouth 11, the other end is outlet flue 12, also comprise stop sleeve 2, stop sleeve 2 is enclosed within entering in mouth 11 of turning shape cylindrical shell 1, form matched in clearance with turning shape cylindrical shell 1, leave certain gap can so that turning shape cylindrical shell 1 with respect to stop sleeve 2, rotate, the top of stop sleeve 2 is fixed with bar stock 3, adopt bar stock 3 can play due supporting role and can not hinder smoke again, bracing frame 3 is positioned at the place of stop sleeve 2 axis coincidings and is fixed with support bar 4, support bar 4 can not do relative motion for being fastenedly connected with bracing frame 3, bracing frame 3 is horizontal stand, the two ends of horizontal stand are separately fixed on the barrel of stop sleeve 2, the central shaft of horizontal stand overlaps with the central shaft of stop sleeve 2, on the inwall at shape cylindrical shell 1 top, turning, be fixed with arc supporting seat 5, the center of arc supporting seat 5 is provided with bearing bracket stand, on bearing bracket stand, be fixed with bearing 6, the top of support bar 4 is fixed in bearing 6, conveniently make arc supporting seat 5 around the rotation of the axle center of support bar 4, the edge of arc supporting seat 5 is fixed on the inner roof wall of turning shape cylindrical shell 1, adopting arc supporting seat 5 is in order to prevent that the end of support bar from contacting with the inwall of turning shape cylindrical shell 1, avoiding increasing resistance hinders turning shape cylindrical shell 1 to rotate with the wind, and scuffing turning shape cylindrical shell 1 inwall, by this structure, make to form hanging structure between turning shape cylindrical shell 1 and stop sleeve 2, when having wind, turning shape cylindrical shell 1 can rotate flexibly with the wind.
embodiment bis-, as shown in Figure 2, Figure 4 shows, and for the ease of smoke, bracing frame 3 can also be the perpendicular support of arc, the perpendicular support of arc is also strip, and the two ends of the perpendicular support of arc are separately fixed on the barrel of stop sleeve 2, and the central shaft of the perpendicular support of arc overlaps with the central shaft of stop sleeve 2.The perpendicular support of arc, higher than the top of stop sleeve 2, forms the support of an arc, can avoid flue gas to be blocked in the nozzle of stop sleeve 2, and the while has also shortened the length of support bar 4, and convenient turning shape cylindrical shell 1 relatively rotates with bracing frame 3.Adopting the perpendicular support of arc, shortened the length of support bar 4, avoid occurring the long problem that causes stop sleeve 2 to swing of support bar 4, realized better supporting role, make shape sleeve 1 rotation in turning more flexible, is preferred plan.
further, for fixing more firm, bracing frame 3 can be individual for 1-2, symmetrical, forms cross-shaped.
further, turning shape cylindrical shell 1 is positioned at outlet flue 12 tops and is fixed with wind vane 7, can be convenient when having wind under wind action, be that turning shape cylindrical shell 1 rotates.
further, as shown in Figure 5, Figure 6, for the ease of this device is fixed on chimney, the lower sidewalls of stop sleeve 2 is provided with opening 9, if opening 9 can make the below of stop sleeve 2 radially produce certain stroke, on the barrel of opening 9 both sides, along the direction perpendicular to barrel, be fixed with respectively stator 8, two stators 8 fastening by a horizontal level bolt and nut.During installation, can unclamp nut bolt, the below of stop sleeve 2 is enclosed within on chimney, and then nut bolt is tightened.
