Description
Technical field
A kind of scissor-type sunlight ceiling ventilation unit is the utility model is related to, belongs to industrialized agriculture production and Mechanical course
Field, suitable for heliogreenhouse top portion ventilation management.
Background technology
China's facility cultivation area is sure to occupy first place in the world, but compared with developed countries, China's establishment type is simple, facility
Equipment falls behind, it is impossible to meets the needs of facilities environment regulation and control.
Core apparatus of the top portion ventilation mouth of heliogreenhouse as control heliogreenhouse temperature and humidity condition, is limited by heliogreenhouse
Structure limits, and is not improved and developed at all always.Existing complete heliogreenhouse film is generally divided into three bulks, top
One piece is top ventilating opening film, and middle one piece is daylighting and bottom ventilating opening film, and one piece of bottom is fixed film, is referred to as " skirt
Side ".The top ventilating opening opening and closing mode of existing heliogreenhouse mainly has following two modes, and one kind is wound membrane mode, and another kind is
Membrane mode.The plastic sheeting being fixed on pipe is rolled or spread out, realized logical by the rotation of a galvanized pipe by wound membrane mode
The opening and closing in air port, its operating process are carried out outside heliogreenhouse, and the rotation of galvanized pipe is manually or motor is realized；Membrane mode
Plastic sheeting is drawn over to one's side or flattened by array pulley gear, realizes the opening and closing of ventilating opening, its operating process is in heliogreenhouse
Portion is carried out, and the artificial operation successively for carrying out single group pulley gear, or motor carry out the same of array pulley gear by transmission mechanism
Step operation.
The problem of ponding in ventilating opening canopy film all be present in above two ventilation unit.Northern area summer rainfall it is big and compared with
Frequently, and the sunlight ceiling vent position gradient is smaller at present, impeded drainage, in addition the film at ventilating opening lack non-return,
Locking device, plastic sheeting ductility increases under high temperature, in the case of product rain, because Action of Gravity Field bounces back, just logical
Many water bags are formed between tuyere position and two truss, the normal volume for influenceing ventilating opening is put.Serious causes ventilating opening film to break
Split, ponding pours into interior.The coating steel pipe of wound membrane mode aggravates draining difficulty, and membrane mode stress point is excessively concentrated, do not had
The position of pulley gear traction excessively relaxes, and these all aggravate seeping phenomenon.Conventional settling mode is increase rod or steel
Net, but structure is lengthy and jumbled and produces effects general.
The content of the invention
In order to solve the above problems, the utility model provides a kind of scissor-type sunlight ceiling ventilation unit；This practicality
New Energy is realized to position locking, the purpose of simplifying of structure.
A kind of scissor-type sunlight ceiling ventilation unit, including it is fixed support, fork-shearing frame, ventilating opening push-rod electric machine, spacing

Not Kong Zhi fork-shearing frame it is flexible, the base of every push-rod electric machine is fixed on fixed support, and fixed support is fixed on daylight
Behind greenhouse on roofing；Two scissors rods of each fork-shearing frame head end are separately fixed on fixed support, and scissors rod can only be with
For circular-rotation is made in the center of circle and can not move up and down, another scissors rod can only move linearly tie point up and down along fixed support
And circular-rotation can not be done；The scissors rod to move linearly can only be done while be connected with the push rod of ventilating opening push-rod electric machine, divulged information
Under the drive of mouth push-rod electric machine, the flexible of fork-shearing frame is realized；Described film fixing groove is fixed on the scissors rod of fork-shearing frame end
On, for fixing ventilating opening plastic sheeting；Described spacing slide rail is two, and spacing slide rail is fixed on heliogreenhouse internal truss frame
On, the north-south gradient of spacing slide rail is identical with the gradient of fork-shearing frame, both keeping parallelisms；Spacing pulley is movable to be arranged on limit
In the slide rail of position, spacing pulley is connected with film fixing groove.
Plastic sheeting the North at the top portion ventilation mouth of heliogreenhouse is fixed on heliogreenhouse adverse grade outer surface, it is impossible to is moved
Dynamic, its south is fixed in described film fixing groove, is moved with the movement of film fixing groove.When ventilating opening push-rod electric machine
When push rod stretches out upwards, fork-shearing frame elongation is promoted, the film fixing groove for being fixed on fork-shearing frame end is moved southwards along spacing slide rail,
The plastic sheeting being fixed in film fixing groove is driven also to move southwards, one piece plastics film is by north orientation south integrally closed；When logical
When the push rod of air port push-rod electric machine is fully extended, plastic sheeting is flattened completely, and ventilating opening is closed；When the push rod of push-rod electric machine shrinks
When, pull fork-shearing frame to shrink, the film fixing groove for being fixed on fork-shearing frame end is northwards moved, and drive is fixed in film fixing groove
Plastic sheeting also northwards move, one piece plastics film is integrally opened from south to north, and as plastic sheeting collapses, ventilating opening is opened
Open.Spacing pulley in spacing slide rail is connected with film fixing groove, is risen during being moved back and forth in film fixing groove north and south
To booster action, make the motion stabilization of film fixing groove smooth.
