Abstract
The invention relates to a plant ventilation device with opening and closing functions, which consists of rib plates, water tanks, outer arc plates, flashing plates, rain sheltering plates, valve plates, connecting rods, a drag link, a speed reduction system and a motor, wherein the two rib plates are vertically and fixedly arranged on the water tanks; openings are reserved on the middle parts of the inner sides of the rib plates; the outer arc plates are arranged along the outside edges of the rib plates; the flashing plates are connected with the lower parts of the outer arc plates, and are arranged outside the water tanks; the two rain sheltering plates are erected on the openings on the middle parts of the rib plates to form a herringbone; the two valve plates are positioned under the rain sheltering plates; one end of the connecting rod is connected with the corresponding valve plate, and the other end of the connecting rod is connected with the horizontally arranged drag link; and the tail end of the drag link is connected with the motor by the speed reduction system. Compared with the prior art, the ventilation device has a secure structure, high wind resistance and high ventilation performance, is applied to cities suffering from more intensive wind, such as cities by the sea and the like, and can conveniently adjust the temperature of a plant by the valve plates with the opening and closing functions.
Description
Technical field
The present invention relates to a kind of ventilation unit, especially relate to a kind of plant ventilation device with keying function.
Background technology
The principle that the hot pressing of air and blast are formed:
Hot pressing: after the air heats in factory building, volumetric expansion, unit weight diminishes, make the air inside and outside factory building form gravitational difference, outdoor air just enters indoor from the bottom of factory building, and indoor air is from the position discharge chamber of upper opening, circulation like this, reaches the object of ventilation.
Blast: when air-flow blows to the wall in house, change the flow direction of air-flow, make the pressure increase of windward side, produces malleation; The current path of the top in house narrows, and flow velocity strengthens, and produces negative pressure; The back side of factory building, air-flow forms vortex, and air thins out, and produces negative pressure.Therefore, establish air inlet at the zone of positive pressure of factory building, negative pressuren zone establishes exhaust outlet, and air just enters indoor from air inlet, and indoor gas drains into outdoor from exhaust outlet, reaches the object of ventilation.
The ventilation of factory building divides force ventilation and gravity-flow ventilation two kinds: force ventilation is power drive with mechanical ventilation equipment, makes air flow and ventilate.Gravity-flow ventilation is the natural flow utilizing the hot pressing of air and the effect of blast and form air, thus reaches the object of ventilation, without the need to power, pollution-free, environmental protection, energy-conservation.Domestic roofing ventilation unit development in recent years is very fast, but substantially continue to use the mentality of designing in rectangular ventilation skylight, only change the shape of outer arc, do not do substantial change, wind resistance is not strong, existing ventilation unit has stronger wind resistance, but cannot equip valve plate, uncontrollable adjustment factory building temperature.
Summary of the invention
Object of the present invention is exactly that having of providing a kind of wind resistance good opens and closes the plant ventilation device of function in order to overcome defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A kind of have the plant ventilation device opening and closing function, it is characterized in that, this ventilation unit is by gusset, tank, outer arc plate, flashing plate, weather shield, valve plate, connecting rod, Drag link, deceleration system and motor composition, described gusset has two pieces, vertical setting is also fixedly located on tank, middle part inside this gusset offers opening, described outer arc plate is arranged along the edge in the outside of gusset, described flashing plate is connected with the bottom of outer arc plate, be arranged on the outside of tank, described weather shield has two pieces, be located on the opening in the middle part of gusset in " people " shaped frame, described valve plate has two pieces, be positioned at immediately below weather shield, one end of described connecting rod is connected on valve plate, the other end is connected with Drag link, this Drag link is in being horizontally disposed with, the end of Drag link is connected with motor by deceleration system.
The shape of described outer arc plate is identical with the shape outside gusset.
Be the ramp shaped that inclination angle is 20 ° in the middle part of described flashing plate, for deriving the rainwater that outer arc plate edge leaks down.
The open and close under the drive of motor of described valve plate, during unlatching, valve plate is vertical state, and during closedown, valve plate is level.
Compared with prior art, the present invention is firm in structure, and wind resistance is good, and wind resistance higher grade, is applicable to the larger city of the wind-force such as seashore and uses.In addition, the valve plate of installation can be opened and close, thus the convenient temperature regulating factory building, performance of ventilating is excellent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the valve plate opening of this ventilation unit;
Fig. 2 is the structural representation of the valve plate closed condition of this ventilation unit.
1 be gusset, 2 be tank in figure, 3 be outer arc plate, 4 be flashing plate, 5 be weather shield, 6 be valve plate, 7 be connecting rod, 8 be Drag link, 9 deceleration systems, 10 are for motor.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
