Description
Technical field
What the present invention relates to is special Polyhouse technology, is more particularly the multi-layer heat preserving plastic-steel booth for the industry such as agricultural planting, fishery cultivating layering plastic cover greenhouse membrane structure.
Background technology
Existing cultivation or planting greenhouse are divided into two kinds substantially: one is shed; One is winter brooder.Above-mentioned booth majority is skim structure, also has two-layer film configuration, and its structure fixed single, heat-insulating property is poor.
The basic structure of shed is the arched framework outer cover plastic sheeting that the materials such as, bamboo pole big with cement, iron pipe, bamboo make.This greenhouse structure is simple, and rapid heat dissipation, heat insulation effect is poor.Carry out planting vegetable with this canopy or cultivate impact and the restriction that ginseng abalone shrimp is vulnerable to outside air temperature very much, generally use in season in spring and autumn two.To winter once temperature drops to subzero, this canopy just can not adapt to the growth requirement of vegetables and ginseng abalone shrimp, substantially stops using if do not added other temperature-boosting measure.
The basic structure of winter brooder is: one side is plastic film covering face, and other faces are heat-preserving wall, and usually, heat-preserving wall is that north or north add thing face; Plastic film covering face is towards (i.e. sunny slope) covered with plastic film in the south, woven straw or insulation quilt are added in the outside of plastic sheeting, the heat insulation effect of this green house of vegetables is more better than shed, winter is generally when outdoor night environment temperature reaches subzero 4-8 DEG C, its temperature of shed only can remain on 3-5 DEG C above freezing, and vegetables can only be kept not to be damaged by frost; In the winter of cold, when nighttime temperature is low to moderate subzero more than 10 DEG C, it can not resist the invasion and attack of the outer cold air of canopy.In order to increase the temperature in canopy night, there is increase energising to heat or heat with fire or overlap a hut etc. way again in booth, both the energy was wasted, turn increase unsafe hidden danger, and all there is operation inconvenience, the problems such as cost increases, heat insulation effect difference, existing booth can not meet crops and aquaculture uses Production requirement, and the necessary requirement of growth promoting effects.
Summary of the invention
One is the object of the present invention is to provide to eliminate above-mentioned shortcoming, have rational in infrastructure, skeleton is firm, layered coverage closes, film drawing is convenient, pulling open daytime can sunlight thoroughly, night is closed can be incubated warm, collection printing opacity, ventilate and be incubated the multi-layer heat preserving plastic-steel booth be integrated. especially adopt multilayer tractive plastic film covering, can immediately open or close every layer film voluntarily, form plantation or the cultivation greenhouse of a kind of printing opacity and insulation, i.e. multi-layer heat preserving plastic-steel booth, the sunlight improving plantation or cultivation greenhouse absorbs and temperature maintenance effect, improve the harvest of plantation or cultivation, the structure of this booth was both applicable to shed, also winter brooder and other canopies is applicable to, desirable for planting the special purpose device with the layering closing structure of cultivation greenhouse.

Embodiment: for three-layer thin-film arch form booth:
This novel booth is the green house of vegetables be assemblied to form by plastic material and steel purlin frame.Be made up of parts such as plastic material, steel purlin frame, trapezoidal bracing frame, slide fastener, booth adventitia, booth inner membrance, machine driving.Its inner membrance can be combined into retractable movable film that is two-layer or multilayer as required, and completes folding and unfolding action by machine driving, reaches the effect of resisting cold insulation.
Multi-layer heat preserving plastic-steel booth is: the booth of plastic-steel structure, wherein,
1, steel purlin frame: altogether for two-layer up and down.For strengthening intensity, upper strata by galvanizing band plate through cold rolling one-tenth C or U-shaped steel as Fig. 5, lower floor is galvanizing band plate through cold rolling one-tenth " several " or π shaped steel as Figure 10.
2, plastic material: plastic material be for two-layer insulation film and custom-designed two ends with slideway and side groove, the assembly of middle upper and lower surface band groove, as Fig. 6.
3, bracing frame: be the trapezoidal bracing frame with screw hole.
Assembled: steelframe, plastic material, trapezoidal bracing frame are spliced through screw, be assembled into the Plastic steel framework of booth, bracing frame stands in the middle of steel purlin frame and plastic material and between the twice section bar of skeleton bottom respectively, play to connect and support, upper steel purlin frame through trapezoidal back-up block and middle plastic material, plastic central section bar through trapezoidal bracing frame and bottom plastic section bar, bottom plastic section bar again liner on the steel band being with reinforcing rib, be connected and fixed by screw, be assembled into a complete plastic-steel big-canopy framework.
4, traction belt: adopt the traction belt of band chain bud to be rely on continuously arranged chain tooth to replace pulley, the cloth end of traction belt and the Film laminated of insulation layer, increment seals in the slideway of plastic material, adopt and namely complete the combination with plastic sheeting in this way, thin film insulating layer is well connected with big-canopy framework, is also beneficial to the curling gathering of plastic sheeting.
5, greenhouse film: booth adventitia, for the view picture covered on skeleton fixes film.
The two-layer inner membrance of booth is the plastic sheeting set according to left and right sides skeleton spacing dimension, the two ends, left and right of plastic sheeting and the cloth end compound of slide fastener, article two, draw the slideway that toothed one end seals in plastic material, folding folding and unfolding is carried out by machine driving, it is bent that daytime draws two-layer inner membrance in circle, make the crop in canopy fully absorb photo-thermal, before darkness, two-layer or multilayer inner membrance are launched, play insulation effect.
6, machine driving: the transmission system that this machine driving is made up of film rolling axis, take-up spool, gearbox, motor etc., execution under the regulation and control of gearbox, realizes folding folding and unfolding that is two-layer or multilayer inner thermal insulating layer.
The interior hut of booth of being everlasting in the past, be incubated by this measure, and then improve the temperature of booth, this way can make temperature of shed be kept and improve.But because overlapping a hut in booth again, the covering of bilayer film will make light transmittance be affected, and can affect the irradiation of sunlight by day, and then have impact on soil and crops to the absorption of heat energy.In booth many dresses which floor can the plastic sheeting of movable, folding and unfolding arbitrarily, daytime pulls open daylighting, and make it absorb sunlight and heat energy fully, close shading in the evening, do not make light fall apart outward.Segmented thin films is drawn in daytime, makes many as far as possible some photo-thermal of absorption in canopy, improves the temperature in canopy with this, can decontrol by movable plastic sheeting, close booth before darkness, the heat energy absorbed daytime in canopy is kept preferably.Reach the effect of insulation.Make the plastic sheeting that installs additional can be movable, just must install slideway additional, make the plastic sheeting that installs additional movable in the direction of regulation, employing plastic irregular profile, be convenient to machine-shaping, compensate for effective linking and activity that simple steel frame construction cannot realize plastic sheeting; Simple plastic construction cannot reach again the object of load-bearing, plastic material is designed sliding way, is assembled on steelframe.Both splice mutually, namely add the function of big-canopy framework, realize coordinating of skeleton and film, keep again and add the intensity of big-canopy framework.
