The regulation device comprises a structural support which is arranged at an air vent of a roof, wherein exhaust outlets are formed on two sides of the structural support symmetrically; and the wind sheltering valve plates capable of regulating the sizes of the exhaust outlets are hinged with two sides of the structural support symmetrically. The regulation device is characterized in that a driving device is arranged in the middle in the structural support, and lead screw driving mechanisms are arranged on two sides of the driving device symmetrically; two output shaft ends of the driving device are coaxially connected with lead screws of the lead screw driving mechanisms respectively; and nuts of the lead screw driving mechanisms are connected with the free ends of the wind sheltering valve plates by connecting rod mechanisms respectively. The regulation device has the advantages that 1, the device is compact in structure, and reliable in operation, and the opening and closing of the wind sheltering valve plates are controlled by the lead screw driving mechanisms, and an out-of-control phenomenon of the wind sheltering valve plates can be avoided, so that the wind sheltering valve plates are stable in opening and closing, high in stability and long in service life; and 2, the wind sheltering valve plates on two sides are driven simultaneously to be opened by two output shafts of the driving device and lead screw driving mechanisms, so that the wind sheltering valve plates are high in synchronism.
Description
Technical field
The utility model relates to a kind of adjusting device, particularly a kind of roof ventilator wind sheltering valve plate adjusting device.
Background technology
The roof ventilator of gravity-flow ventilation is extensively adopted in the design of large scale industry factory building roof ventilation at present.Wherein, the open-close type roof ventilator is to control vent flow through the keying of wind sheltering valve plate to regulate with the insulation of building, and wind sheltering valve plate one end and the ventilator structure of this roof ventilator are hinged, and the other end is realized the control vent flow.The keying of wind sheltering valve plate relies on electronic deceleration device to drive major axis usually and rotates, and relies on the winding and the release that twist in the steel wire rope on the major axis, forms the keying control to the wind sheltering valve plate.This flexible opening-closing control mechanism; Only have unidirectional traction control function, rely on wind sheltering valve plate gravitational orientation when closing, the external force that receives when the wind sheltering valve plate is during greater than himself gravity; Wind sheltering valve plate out-of-control phenomenon will take place, and causes frequent keying of wind sheltering valve plate to cause damage easily.
Summary of the invention
The utility model technical problem to be solved is that a kind of compact conformation, reliable operation will be provided, and the wind sheltering valve plate opens and closes steadily, the roof ventilator wind sheltering valve plate adjusting device of long service life.
The roof ventilator wind sheltering valve plate adjusting device that the utility model relates to; Comprise the structure stand that is installed in the femerell place; Be provided with exhaust outlet in the structure stand bilateral symmetry; Be hinged with the wind sheltering valve plate of scalable exhaust outlet size in the structure stand bilateral symmetry; Its special character is: the middle part is provided with drive unit and is provided with lead-screw drive mechanism in the drive unit bilateral symmetry in structure stand, and two output axle heads of drive unit are connected with the leading screw of lead-screw drive mechanism is coaxial respectively, and the screw of lead-screw drive mechanism is connected with the free end of wind sheltering valve plate through linkage respectively.
Above-mentioned roof ventilator wind sheltering valve plate adjusting device, described drive unit is to be formed by connecting motor and speed reducer.
Above-mentioned roof ventilator wind sheltering valve plate adjusting device; Described linkage is to be contained on the major axis one group and to drive two connecting rods and many groups and carry out two connecting rods and constitute by be installed in major axis, an end fixed card on the structure stand through axle bed; The other end of said driving two connecting rods and the screw of lead-screw drive mechanism are hinged, and the other end of carrying out two connecting rods is hinged with the free end of wind sheltering valve plate respectively.
The utility model has the advantages that: 1, compact conformation, reliable operation, through the switch of lead-screw drive mechanism control wind sheltering valve plate, can avoid wind sheltering valve plate generation out-of-control phenomenon, make the wind sheltering valve plate open and close steadily good stability, long service life.2, the wind sheltering valve plate that drives both sides simultaneously of two output shafts and the lead-screw drive mechanism through drive unit is opened, and wind sheltering valve plate synchronism is good.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation after the wind sheltering valve plate is opened.
Among the figure: motor 1, reductor 2, adapter sleeve 3, leading screw 4, screw 5, bearing 6, structure stand 7 drives two connecting rods 8, deep bead 9, major axis 10 is carried out two connecting rods 11, exhaust outlet 12, wind sheltering valve plate 13, daylighting weather shield 14, end plate 15, collecting gutter 16, axle bed 17.
The specific embodiment
As shown in the figure; This roof ventilator wind sheltering valve plate adjusting device comprises the structure stand 7 that is installed in the femerell place; The middle part is fixed with daylighting weather shield 14 on structure stand 7, and lower edge is fixed with the collecting gutter 16 that colored steel is converted into respectively in the both sides of daylighting weather shield 14.Be symmetrically fixed with arc wind board 9 in structure stand 7 both sides of the edge; Be fixed with end plate 15 respectively at structure stand 7 two ends; Form the exhaust outlet 12 that is symmetrically arranged in structure stand 7 both sides between described deep bead 9 and the daylighting weather shield 14; The upper end symmetry that is positioned at deep bead 9 in structure stand 7 both sides is hinged with the wind sheltering valve plate 13 of scalable exhaust outlet 12 sizes, and wind sheltering valve plate 13 is to be made up of framework and one deck sunlight board that is fixed on the framework outside, to improve the daylighting effect.The middle part is equipped with drive unit in structure stand 7, and drive unit is to be formed by connecting through belt gear motor 1 and double output shaft reductor 2.On structure stand 7, be positioned at the drive unit bilateral symmetry and be provided with lead-screw drive mechanism; Two of said reductor 2 output axle heads respectively with leading screw 4 one ends of lead-screw drive mechanism through 3 coaxial connections of adapter sleeve; On structure stand 7, leading screw 4 rotation directions of two lead-screw drive mechanisms are opposite through bearing 6 and bearing fixing for leading screw 4 other ends of lead-screw drive mechanism.The screw 5 of lead-screw drive mechanism is connected with the free end of wind sheltering valve plate 13 through linkage respectively.Described linkage is to be contained on the major axis 10 one group and to drive two connecting rods 8 and many groups and carry out two connecting rods 11 and constitute by being installed in major axis 10, an end fixed card on the structure stand 7 through axle bed 17 and bearing along structure stand 7 length directions; The other end of said driving two connecting rods 8 and the screw 5 of lead-screw drive mechanism are hinged, and it is hinged with the free end of wind sheltering valve plate 13 respectively along the other end that the length direction of structure stand 7 was uniformly distributed with and carried out two connecting rods 11 that many groups are carried out two connecting rods 11.
