Description

A kind of novel double-layer roofing greenhouse by solar heat
Technical field
The utility model relates to a kind of double-deck roofing greenhouse by solar heat, is applicable to vegetables, flowers, fruit tree etc. that horticultural crop needs controllable environment, anniversary and expert system.
Background technology
Greenhouse by solar heat is the greenhouse structure of China's independent research, there is construction cost low, the features such as good energy-conserving effect, end 2013, China's industrialized agriculture area has reached 3,500,000 hectares, wherein greenhouse by solar heat reaches 880,000 hectares, account for 25% of the facility gross area, rise in fossil energy price, under the background that environmental protection is increasingly strict, greenhouse by solar heat has become China's facilities horticulture Breakthrough in Industry resource bottleneck restriction, keep the important means of the permanently effective supply of agricultural product in winter, wideling popularize and popularizing along with various places vegetable basket project, the construction of greenhouse by solar heat will reach unprecedented scale.
But the subject matter that the greenhouse by solar heat of current China exists is that 1. winter, heat storing and heat preserving performance had much room for improvement.The cladding material mainly individual layer plastic sheeting for farm use of greenhouse by solar heat, thermal insulation quilt or straw screen or mat become the Main Means of night insulation.Thermal insulation quilt or straw screen or mat directly overlay on canopy film by rolling and spreading mechanism, and the overlap joint due to thermal insulation quilt mostly is rope setting fastening, easily occur the situation that overlap joint is not tight; Thermal insulation quilt mostly is felt or lightweight foam material in addition, and night, strong wind easily blew afloat the thermal insulation quilt covered on canopy film, causes indoor heat more lost, reduces the heat insulation effect of thermal insulation quilt.2. existing greenhouse by solar heat is mainly used in winter production, owing to not possessing the facilities such as sunshading and temperature reducing, the crop Long summer cultivation of non-refractory becomes a difficult problem for puzzlement peasant household, " can only stop canopy " at the high temperature season in 7 to August, efficiency utilization greenhouse by solar heat carries out the anniversary or expert system becomes problem anxious to be resolved.3. existing greenhouse by solar heat top ventilating opening mostly is and manually takes off seam, and the weather of blowing and raining can not use; Many insulation in winter by or straw screen or mat cover, also use inconvenience when needing hydrofuge take a breath, need improvement.
Utility model content
The utility model is exactly for the deficiencies in the prior art, a kind of novel double-layer roofing greenhouse by solar heat of proposition, improves greenhouse heat-insulating property in winter, from strong wind, sleety weather on the impact of thermal insulation quilt; Be furnished with external sunshade system simultaneously, can indoor illumination be regulated, avoid crop to be subject to the impact of Exposure to Sunlight high temperature, realize more summer production.
The novel described a kind of novel double-layer roofing greenhouse by solar heat main body of this use comprises heat storing and heat preserving body of wall and Keelof green house two parts, described heat storing and heat preserving body of wall is structurally in east-west, long 60 to 80 meters of thing, north and south span 8 to 10 meters, ridge is high 4 to 5 meters, north, in the east long-pending west are heat storing and heat preserving body of wall, and greenhouse Nan Qiang rises and is more than or equal to 0.100 meter; Described north wall and Nan Qiang top are provided with embedded iron, are spaced apart 0.5 to 2 meters between embedded iron; Outside described southern wall, 0.2 to 0.8 meter of arranges the stake of concrete isolated footing, and stake top, described concrete isolated footing is provided with embedded iron, the absolute altitude of described concrete isolated footing stake embedded iron and spacing and Nan Qiang push up the absolute altitude of embedded iron and spacing identical;
Described Keelof green house is divided into two-layer up and down, and wherein lower floor is main body steelframe, and upper strata is canopy film steelframe; Described main body steelframe welds with Nan Qiang and north wall embedded iron respectively; Described main body steelframe is welded with near 0.5 to 1 meter of of north wall one end and vertically connects steel beam column; One end of described canopy film steelframe is welded on the vertical connection steel beam column of main body steelframe, and one end is welded in the stake of concrete isolated footing;
Described main body steelframe is provided with internal layer electric rolling successively and puts canopy film and electric rolling puts thermal insulation quilt; Described canopy film steelframe is provided with anterior volume film vent window is installed, and canopy film steelframe on outer canopy film is installed successively and electric rolling puts sunshade net; Be provided with internal layer volume film vent window inside the vertical connection steel beam column of described main body steelframe, outside is provided with outer volume by vent window, and described internal layer volume film vent window and outer volume can be adjustable at 0 to 1.0 meter by the opening degree of vent window.
Further, described lower layer main body steelframe is welding arch truss, and upper strata canopy film steelframe is arch steel pipe, the spacing of upper strata and lower floor's steelframe 0.4 ~ 0.5 meter.
Further, front portion volume film vent window 5 window be arranged on canopy film steelframe can be adjustable in 0 ~ 1.5 meter.
Compared with existing heliogreenhouse shed, the beneficial effects of the utility model are:
1, double-deck canopy film greenhouse by solar heat, more traditional greenhouse by solar heat is compared, at night insulation Be very effective cold season.Due to double-deck canopy film and between more stable air layer, such that greenhouse airtight performance improves, heat transfer coefficient reduces, reduce the conducting power of heat, decrease scattering and disappearing of indoor heat.Duplicature covers greenhouse by solar heat nocturnal temperature higher than traditional greenhouse by solar heat, amplitude 1 ~ 14 DEG C.
2, double-deck canopy film greenhouse by solar heat can be opened or delays and cover thermal insulation quilt by more traditional greenhouse by solar heat in advance.If tradition greenhouse by solar heat open thermal insulation quilt too early, outdoor temperature is lower, monofilm insulation poor, easily cause indoor temperature sharply to decline, be down to crop temperature required below, generation freeze injury; Due to double-deck canopy film high insulating effect, between more stable air layer can play again the cushioning effect of cooling, thermal insulation quilt can be opened in advance 0.5 ~ 1.0 hour by more traditional greenhouse by solar heat, delay and cover thermal insulation quilt 0.5 ~ 1.0 hour, extend the indoor crops photosynthetic time, promote plant growth.On the daytime of illumination abundance, internal layer canopy film scrolls up, and near the daylighting of outer canopy film, the energy obtaining sunshine to greatest extent carries out accumulation of heat.
3, electric rolling is put under thermal insulation quilt is arranged on outer canopy film, can avoid the destruction of the diastrous weather such as strong wind, sleet, extend the service life of thermal insulation quilt.Due in the every material of greenhouse by solar heat, thermal insulation quilt investment cost is higher, and service life extends, and reduces loss, uses manpower and material resources sparingly.
4, upper strata canopy film steelframe is provided with electric rolling and puts sunshade net, when summer, illumination was strong, starts electric rolling and put Shading net covering on outer canopy film, regulate indoor illumination, avoid crop to burn, reduce temperature of shed.
5, top is provided with vertical skin volume by vent window and internal layer volume film vent window, and window is positioned at greenhouse peak, is conducive to realizing Ventilation to greatest extent.During closedown, inside and outside bilayer covers, high insulating effect; Open when rolling, window height 0 ~ 1.0 meter is adjustable, and more traditional greenhouse by solar heat ventilation effect is better, can not facilitate conditioning chamber humidity and gas concentration lwevel, be beneficial to plant growth by weather effect.
