Abstract
The invention relates to a roof-windowing single-span plastic greenhouse, belonging to the technical field of plastic greenhouses. The roof-windowing single-span plastic greenhouse is characterized in that one long arch bar and one short arch bar are connected through a connecting piece to form a single arch frame, and the long arch bar and the short arch bar which are arranged at the two sides of the single arch frame and are different in length form a vertical roof ventilating window on the top of the single arch frame; the single arch frames are longitudinally connected on the top of the long arch bars by virtue of a main longitudinal rod to form a main arch frame of the greenhouse; a plastic film is covered on the main arch frame to form the plastic greenhouse; and side ventilating windows are arranged at the two sides of the lower part of the greenhouse. In the roof-windowing single-span plastic greenhouse, the vertical roof ventilating window is arranged on the top of the greenhouse and is matched with the side ventilating windows at the lower part so as to form better hot pressure ventilation effect, thus natural ventilation also can be realized only by utilizing hot pressure even under the windless external condition. In routine production, as the hot pressure ventilation capability is increased, the natural ventilation property of the single-span greenhouse is obviously improved under the combined action of wind pressure and the hot pressure so that the temperature in the greenhouse can not be too high, thus meeting the requirement for crop growth.
Description
Technical field
The invention belongs to the plastic tunnel technical field, be specially single plastic tunnel of top window type.
Background technology
At present, single conventional booth ventilating system is to adopt the form of position vent window at the bottom of the both sides, does not have vent window usually at the top of booth.
Common gravity-flow ventilation is a principle of utilizing blast and hot pressing, because conventional single booth only has vent window in the both sides of low level, the driving force of its gravity-flow ventilation mainly relies on extraneous blast.Because the top does not have vent window, the heat in the booth is easy to accumulate in the booth top, causes temperature of shed high, produces summer such as difficulty etc.

Embodiment
Figure is described further the present invention below in conjunction with the explanation width of cloth.
As shown in the figure; Long arch bar 1, short arch bar 3 connect and compose single Pin bow member through connector 2; Not isometric long arch bar 1, the short arch bar 3 in both sides forms vertical top vent window 16 at its top; Each single Pin bow member vertically connects and composes booth main body bow member through main vertical pole 10 at long arch bar 1 top; Covered with plastic film constitutes plastic tunnel on the booth main body bow member, and both sides, booth bottom are provided with side vent window 17.Vertical top vent window 16 is owing to adopt vertical the setting, can also prevent that rainwater etc. from leaking into booth.Described connector 2 is a vault Y type joint sleeve, is made up of long sleeve pipe 2a, short sleeve 2b and triangle connecting plate 2c welding, and long arch bar 1 passes long sleeve pipe 2a, and short arch bar 3 is pegged graft with short sleeve 2b and cooperated.The dihedral weld seam is adopted in the welding of connector 2, and triangle connecting plate 2c mainly works the effect that is connected of strengthening long sleeve pipe 2a and short sleeve 2b; Through increasing triangle connecting plate 2c, can play the growth fusion length simultaneously, reduce the leg size of angle welding; Avoid the burn-through phenomenon is appearred in the booth thin-wall pipes in carrying out welding process; After connector 2 integral solder are accomplished, carry out galvanizing by dipping again, guarantee its durable years.
The arch bar top ends of long arch bar 1 is connected through roof window vertical rod 9 and short arch bar 3, and roof window vertical rod 9 front sides are provided with retaining film bar 12, and retaining film bar 12 bottoms are connected with short arch bar 3.Cover a monoblock film in long arch bar 1 and the roof window vertical rod 9; Its vertical top vent window 16 adopts volume films mode of windowing; The end of volume film window is provided with film rolling rob 13; Film rolling rob 13 connects and cooperates with roof window vertical rod 9, retaining film bar 12 retainings; The inboard of its volume film is blocked by roof window vertical rod 9, and the outside of volume film is by retaining film bar 12, when roof window is closed; Film rolling rob 13 is clamped by roof window vertical rod 9 and retaining film bar 12, guarantees the sealing of roof window.
Roof window vertical rod 9 bottoms of each single Pin bow member vertically are provided with draw-in groove 14.The windowing of the plane that each short arch bar 3 the constitutes vertical top of formation vent window 16 between last draw-in groove 14 and main vertical pole 10.Last draw-in groove 14 is used for fixing the film that short arch bar 3 coverings come up, and with the volume film window of vertical top vent window 16 certain registration is arranged.Each single Pin bow member vertically connects at short arch bar 3 tops through inferior vertical pole 8.Main vertical pole 10 tops of each single Pin bow member vertically are provided with top draw-in groove 11.Long arch bar 1 is that a monoblock film covers with the volume film window of vertical top vent window 16, and film is fixing by the top draw-in groove on the main vertical pole 10 11, the vertical top of the sagging covering of unnecessary film vent window 16.Long arch bar 1 bottom vertically is provided with right draw-in groove 6, and short arch bar 3 bottoms vertically are provided with left draw-in groove 5.Long arch bar 1 bottom vertically is provided with right pull bar 7, and short arch bar 3 bottoms vertically are provided with left lever 4.The film-pressing line 15 of setting and its compression fit on main vertical pole 10 and the plastic film, film-pressing line 15 two ends are fixedly connected with ground, both sides grasp, and the greenhouse film film-pressing line 15 after the tension presses on main vertical pole 10 and the greenhouse film.Main vertical pole 10 is because of bearing the pressure that film-pressing line 15 brings, and time vertical pole 8, left lever 4, right pull bar 7 materials want big relatively.
Through vertical top vent window 16 is set at the booth top; Match with the side vent window 17 of bottom; Form the supporting vent window of height; Because booth has greenhouse effect, the temperature in its canopy is higher than outside the canopy, and the air that extraneous greenhouse is low is come in from low level side vent window 17; Vertical top vent window 16 is gone out from the top; Form hot pressing preferably and ventilate,, also can realize gravity-flow ventilation even under the calm state in the external world, only utilize hot pressing.In daily production, owing to increased the hot pressing draught capacity, under both common superpositions of blast hot pressing, significantly improved the gravity-flow ventilation performance of single booth, temperature of shed can be not too high, satisfies the plant growth requirement.When vent window 16 is opened with side vent window 17 on vertical top, rely on the hot pressing blast to ventilate ventilation volume 2 minutes 1 time; Wind loading rating is greater than 25 meter per seconds (wind carries greater than 0.4 kN/m2); Snow load is compared with the common booth of same specification greater than 0.2 kN/m2, and the cost increase is lower than 35%.
