Embodiment
Foundation: lay the ground pipeline in grade level, the outer 0.3m profile place of pipeline is provided with the underground placement heat radiation of horizontal bottom barrier wall, underground degree of depth 0.5m is two-layer cement plate therebetween glass fiber thermal insulation board, subterranean pipe line is distributed in the ground pipeline with interior 0.5m zone, 0.3m under imbedding in the canopy, column is connected with the ground transverse tube by connecting foundry goods, and body of wall is clipped in the column both sides.
Body of wall: the body of wall in greenhouse adopts the cotton plate of cement plate compound glass to assemble with the airtight back of aluminium foil interlayer, the hollow distance is greater than column diameter, usually get 25～50 millimeters according to the region heat-insulation layer, the printing opacity body of wall adopts structure as shown in Figure 5, and thickness is identical with other structure walls.
The light transmission in greenhouse: the light transmittance height, the light thermal property in greenhouse is good.The absolute value that the greenhouse light transmittance advances the greenhouse intensity of illumination thoroughly owing to the increase of increase back glazed area still improves, and guarantees the normal growth of crop, and summer can be with condenser mirror as other purposes, and the light transmittance in greenhouse improves more than 50%.
The heat-insulating property in greenhouse: hollow sandwich, the heat-insulating property in raising greenhouse cuts down the consumption of energy, and improves the hothouse production benefit, and the insulation ratio in greenhouse is greater than more than 1.5, and the heat-insulating property in greenhouse will be far superior to other greenhouses.
The coating steel pipe structure is exempted the building lot construction project, improves the durability and the removable construction in greenhouse, improves soil nutrient and imitates late and soil physical property, can realize the processing of brooder land ecology.
The factor that influences the greenhouse durability is except the ageing-resistant performance of greenhouse material, and is also relevant with the bearing capacity of greenhouse agent structure.The durability of light transmissive material shows that also on its light transmittance attenuation degree in time, glass is the minimum light transmissive material of attenuation degree, has improved the life-span except self intensity.
The bearing capacity of design greenhouse agent structure is directly related with the reproduction time limit that strong wind, snow load occur.Pipe steel construction greenhouse service life is more than 30 years, and design wind, snow load adopt met peak loads in 30 years one, in the snow, can utilize Salar light-gathering irradiation and brooder solar heat-preservation to carry out snow melt work behind the snow.
Because the greenhouse operation is in high temperature, high humidity environment for a long time, the surface anticorrosion of member has just become to influence a greenhouse key factor in service life.For the steel construction greenhouse, stressed agent structure generally adopts the heavy wall galvanized pipe, himself resistance to corrosion height, and thickness of coating requires to reach more than the 200 μ m.
Brooder designs according to existing industry standard
JB/T 10286-2001 greenhouse by solar heat structure; JB/T 10292-2001 greenhouse engineering term; JB/T 10294-2001 Wet-curtain temperature reducing device; JB/T 10296-2001 greenhouse electric wiring design specification; JB/T 10297-2001 greenhouse heating systematic design discipline.
Brooder can be done the lucifuge processing or close pipeline summer, and perhaps valve-off also can be used as other purposes with thermal source.
The explanation of printing opacity body of wall implementation:
Rigid trestle can adopt the general method of attachment of steel tubes to manufacture framework, reserves the link with connected component.
Glass, caustic surface, condensing body adopt safety glass, as required to alleviate wall weight, printing opacity is a parameter request, and the magnifying glass condensing body is bonding with transparent colloid, and focal point is according to body of wall size and formal parameter and the different interval branch of absorber form selection.The metal fin tube heat sucker, but can the high-frequency welding fin also extrusion modling behind the suit, tubing is seamless pipe, phosphatization is handled, welding needs the end that be connected with other parts and is connected general valve.Top heat-insulation layer next-door neighbour uptake, metal accumulation of heat part is processed with the moulding that increases area of dissipation, and general preservative treatment is done on the surface.The hot blast input is selected general nonmetallic materials pipe seal sleeve for use, reserves the link that can connect general flexible pipe.
Various parts are assembled successively, and assembling finishes, and the heat sink angle of inclination is according to using local solar radiation angle Selection.
Solar energy is radiated on the heat absorption metal fin pipe and absorption film of optically focused heat absorbing units by condensing glass, 120 ℃ focal point temperature makes the inner heat storage medium vaporization of heat absorption metal fin pipe, the heat storage medium gas that enters heat exchanger in the thermal isolation and heat storage jar and heat storage liquid heat-shift be after liquid back pipe is got back to heat-accumulator tank, but heat absorption and heat-accumulating process can with thermal process also branch adapted heat after the accumulation of heat synchronously.
The explanation of heating implementation;
Note installing the downward-sloping angle of withdrawing fluid.
Send the explanation of fan heater implementation:
Return air link, return air fillter section, air-supply link, powered air-purifying device, hot blast interchanger, hot blast interchanger inlet end, fan supporter, blower fan, fans, hot blast interchanger liquid returning end are installed successively according to order illustrated, fixed support is set up in the outside, air outlet can extend guiding, and filter is convenient to cleaned and changed.
The insulation material implementation explanation of heat-storage heat preservation material:
With connector nonmetal rigid plate and inboard insulation material, forming metal heat accumulation member are coupled together, and set up insulation material in the nonmetal rigid plate outside; Connector is general bolt.
