Abstract
The utility model relates to a ventilation device widely applied to various greenhouses and breeding houses. The greenhouse ventilation device comprises a plurality of greenhouse frameworks, middle supporting beams, supporting cross beams, two windows, pluggings, a plurality of arc-shaped opening bars, pulleys and pull cords. The middle supporting beams are vertically connected at the top end of each greenhouse framework, the supporting cross beams are vertically connected at the top end of each middle supporting beam, the windows are connected on two sides of the supporting cross beams through hinges, pluggings are arranged on the left side and the right side of the windows respectively, the arc-shaped opening bars are arranged on vertical beams of the windows at equal intervals, a thread-through hole is formed in the top end of each arc-shaped opening bar, the pulley is arranged at a position, close to each arc-shaped opening bar, of each greenhouse framework, and each pull cord with one end connected to the thread-through hole of each arc-shaped opening bar passes each pulley and the other end of the pull cord is connected to a main pull cord. The greenhouse ventilation device is simple in structure, convenient to open, free of waterlogging in rainy days and good in heat insulation.
Description
Technical field
The utility model relates to a kind of ventilation unit that is widely used in various green houses and cultivation colony house.
Background technology
Current green house ventilates and normally adopts the mode that skylight is set in the open top of booth, said method need to increase frame on booth, with a bar volume film, realize closing and opening of skylight simultaneously, the shortcoming of said structure is, edge increase frame due to skylight, so the inner easily ponding of frame cannot be cleared up when rainy, thereby cause roll bar volume film difficulty, cannot realize the unlatching in skylight; In the winter time because ponding freezes, the destruction that also can cause day fenestrated membrane, makes cold air enter booth inside, destroys heat insulation effect in addition.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, and it is convenient to open, and does not have the phenomenon of ponding to occur, the ventilation unit of the green house of high insulating effect when rainy.
The purpose of this utility model is to realize like this, this ventilation unit comprises a plurality of big-canopy frameworks, intermediate supports beam column, supporting traverse, forms, shutoff, arc all-or-nothing piece, pulley and stay cord, described intermediate supports beam column is vertically connected to the top of each big-canopy framework, supporting traverse is vertically connected on the top of every intermediate supports beam column, forms are connected to the both sides of supporting traverse by folding, shutoff is arranged on the left and right sides of two forms, described a plurality of arc all-or-nothing piece is uniform to be disposed on the vertical beam of forms, the top of each arc all-or-nothing piece has through wires hole, near on the big-canopy framework of each arc all-or-nothing piece, be provided with a pulley, stay cord other end after pulley that one end is connected to through wires hole on arc all-or-nothing piece is connected on main stay cord.
The utility model is owing to adopting symmetrically arranged two forms, thus can according to wind direction, open the forms of a side with the wind, when there is no wind, can open the forms of both sides simultaneously, have a kind of simple in structurely, it is convenient to open, when rainy, do not have the phenomenon of ponding to occur, the advantages such as high insulating effect.
Accompanying drawing explanation
Fig. 1 is green house ventilation unit overall structure schematic diagram.
Fig. 2 is that the A of the utility model Fig. 1 is to perspective view.
Fig. 3 is that the B of the utility model Fig. 1 is to perspective view.
Embodiment
By accompanying drawing 1, 2, shown in 3: this ventilation unit comprises a plurality of big-canopy frameworks 1, intermediate supports beam column 2, supporting traverse 3, forms 4, shutoff 5, arc all-or-nothing piece 6, pulley 7, divide stay cord 8 and main stay cord 9, described intermediate supports beam column 2 is vertically connected to the top of each big-canopy framework 1, supporting traverse 3 is vertically connected on the top of every intermediate supports beam column 2, forms 4 are connected to the both sides of supporting traverse 3 by folding, shutoff 5 is arranged on the left and right sides of two forms 4, described a plurality of arc all-or-nothing piece 6 is uniform to be disposed on the vertical beam 11 of forms 4, the top of each arc all-or-nothing piece 6 has through wires hole 9, near on the big-canopy framework 1 of each arc all-or-nothing piece 6, be provided with a pulley 7, one end is connected to minute stay cord 8 other end after pulley 7 of through wires hole 10 on arc all-or-nothing piece 6 and is connected on main stay cord 9.
When booth need to ventilate, as long as two forms 4 main stay cord 9 is below pulled out, thereby uniform each minute stay cord 8 being connected on main stay cord 9 just outwards outwards opened spacing lower each the arc all-or-nothing piece 6 that synchronously pulls at pulley 7 by two forms 4 to big-canopy framework 1; Unclamping 9 two forms 4 of main stay cord closes opposite direction return.
