Description
Technical field
This utility model belongs to heliogreenhouse environmental Kuznets Curves field and in particular to a kind of multisection type inside holding for greenhouse
Shading system and the greenhouse containing this inside holding shading system.
Background technology
At present, the major way that heliogreenhouse and plastic greenhouse cultivation Yi Cheng China industrialized agriculture produce, cultivated area and
Yield increases year by year.But affected by heliogreenhouse and hot house self structure, generally existing environment conditioning ability is weaker, all
As: night insulation effect is poor, and daylight is strong, temperature height etc..The appearance of problem above, not only constrain existing heliogreenhouse and
Hot house product quality and the lifting further of yield, also result in the waste of resource simultaneously.How to solve existing greenhouse knot
The night insulation of structure, daytime problem of lowering the temperature is extremely urgent.For this reason, provide a kind of night can reduce inside greenhouse heat scattering and disappearing,
Can reasonably control daytime in entrance greenhouse again and radiate regulator control system, greenhouse energy saving be built very necessary.
Greenhouse film appearance is coated with sunshading and thermal insulating material mostly at present, but the weight capacity in view of greenhouse film, many
The sunshading and thermal insulating material of number greenhouse film appearance is very thin, or even only a limited number of layer, this sunshade allowing for this greenhouse and guarantor
Warm ability is restricted, thus affecting plant growth.Although existing greenhouse adopts internal sunshade heat-insulation system, structure is loaded down with trivial details, raw
Produce high cost, and sunshade curtain only has complete one piece it is impossible to flexibly control indoor temperature and intensity of illumination.
Utility model content
(1) technical problem to be solved
The technical problems to be solved in the utility model is to provide a kind of structure simple, high efficient and reliable, and can flexibly control temperature
Chamber interior temperature and the multisection type inside holding shading system for greenhouse of intensity of illumination；And provide one kind and contain this interior guarantor
The greenhouse of warm shading system.
(2) technical scheme
In order to solve above-mentioned technical problem, this utility model provides a kind of multisection type inside holding sunshade system for greenhouse
System, located inside greenhouse, comprising: sequentially parallel arranged and collectively form described multisection type inside holding shading system sun face
Multistage inside holding ante-venna, for guide the described inside holding ante-venna direction of motion and support described inside holding ante-venna pressure/
Shade supporting wire, for the multiple curtain drawing mechanisms driving described inside holding ante-venna to launch or draw in, one is used for driving described in each
The drive shaft of curtain drawing mechanism work, and a motor driving described drive shaft rotation；Described curtain drawing mechanism includes one and closes
That closes drives wirerope and an angle pulley for changing the described driving wirerope direction of motion, described driving wirerope one ends wound
In described drive shaft, and the relative other end is wound in described angle pulley；Described inside holding ante-venna side is fixed, and relatively
Opposite side as folding and unfolding end respectively with each described drive wirerope is connected, and each described drive wirerope synchronization drive
Under, the folding and unfolding end of described inside holding ante-venna is secured relative to end and is extended or contractile motion, so that this section of described inside holding
Ante-venna is smooth to launch or draws in；Each described driving wirerope synchronous rotary is ordered about in described drive shaft rotation, and then drives each section
Described inside holding ante-venna is smooth successively to launch or draws in successively, thus covering all or part of planting area in described greenhouse.
Multisection type inside holding shading system for greenhouse of the present utility model, compared to external thermal insulation shading system, it can

Description for making the present embodiment inside greenhouse space is more convenient, using rear wall of greenhouse 13 place direction as rear portion,
The direction relative with rear wall of greenhouse 13 is as front portion；Based on this explanation, three sections of inside holding ante-vennas are respectively first from front to back
Inside holding ante-venna 1, the second inside holding ante-venna 2 and the 3rd inside holding ante-venna 3, and each segment length is equal, but with regard to width
Speech: the second inside holding ante-venna 2 ＞ the first inside holding ante-venna 1 ＞ the 3rd inside holding ante-venna 3.
Drive shaft 5 rotation is ordered about each and is driven wirerope 6 synchronous rotary, and then drives above-mentioned three sections of inside holding ante-vennas successively
Smooth launch or draw in successively, thus all or part of planting area in masking greenhouse accordingly.
The fixing end of above-mentioned inside holding ante-venna and each double grooved pulley 10 are both secured to Keelof green house 12；Pressure curtain line 7-
Greenhouse basis 14 is fixed in 1 and shade supporting wire 7-2 equal one end, and the relative other end is fixed on Keelof green house 12；Each commutation is slided
Wheel 11 is both secured to greenhouse basis 14；Drive shaft 5 is fixed on rear wall of greenhouse 13 by itself bearing, and reducing motor 4 is fixed on temperature
Wall 13 behind room.
In work, when needing sunshade, reducing motor 4 rotates forward, and drives drive shaft 5 to rotate, then drive shaft 5 is ordered about
Drive wirerope 6 to rotate, and then, drive itself rotary motion of wirerope 6 to be converted to linear motion, in each double grooved pulley 10
Under guiding, wirerope 6 is driven to pass through respectively to drive section bar 8 and fixation/buffer unit 9 to draw the three, the second and from back to front successively
First inside holding ante-venna synchronizes stretching, when the less 3rd inside holding ante-venna 3 of superposed displacement reaches
During range, limited by the driving section bar 8 being connected with the 3rd inside holding ante-venna 3 and fixation/buffer unit 9 action, now drive
The driving force of dynamic wirerope 6 be enough to overcome itself frictional force with fixation/buffer unit 9, so, top the 3rd inside holding ante-venna
3 stopping actions, and drive wirerope 6 to continue to drive the second inside holding ante-venna 2 at middle part and the first inside holding ante-venna 1 of bottom
Stretch, in the same manner, until the second inside holding ante-venna at the first inside holding ante-venna 1 of bottom and middle part reaches maximum row in succession
Journey, all inside holding ante-vennas are all fully deployed, and system completes to stretch work, and then realizes sunshade and the insulation work(of heliogreenhouse
Energy.When needing printing opacity, reducing motor 4 reversely rotates, and drives drive shaft 5 to reversely rotate, and then makes driving wirerope 6 pass through commutation
Pulley 11 does counter rotational movement, and ibid, the described multisection type inside holding shading system for greenhouse completes inside holding and hides principle
The gathering work of positive curtain, thus reach the purpose increasing intensity of illumination.
Embodiment of the present utility model is given for the sake of example and description, and is not exhaustively or to incite somebody to action
This utility model is limited to disclosed form.Many modifications and variations are aobvious and easy for the ordinary skill in the art
See.Select and description embodiment is in order to principle of the present utility model and practical application are more preferably described, and make this area
Those of ordinary skill is it will be appreciated that this utility model is thus design is suitable to the various embodiments with various modifications of special-purpose.
