Abstract

The utility model discloses a solar multi-span greenhouse, which is integrally characterized in that more than two units form a group of multi-span structures, the multi-span structures form a uniform stepped shape of one unit higher than another unit, a group of arch frames is arranged above each unit, two ends of each arch frame are fixed on a cross beam, wherein the lighting angle alpha is over 40 degrees and the greenhouse is 30-100cm lower than the ground. The solar multi-span greenhouse belongs to a large scale greenhouse without warming up, which can be applied to not only seeding culture and production of vegetables but also seeding culture and production of macrophyte such as flowers and fruit trees, and even high fruit trees can be planted in the greenhouse. The utility model is adaptable to meeting requirements of vast rural areas and enterprises and public institutions.

Description

Solar energy connects strides the greenhouse

Technical field

The utility model relates to a kind of greenhouse, refers in particular to be used for north cold area, and the solar energy that need not any warming-up device connects strides the greenhouse.

Background technology

Produce thermophily plants such as vegetables, flowers, fruit tree in the winter of northern area cold, large greenhouse, the homemade greenhouse of existing import all need increase the warming-up device oil firing or burn coal can make plant growing, and this had both wasted the energy, had destroyed environment again.Even like this, also be inadequate growth, do not reach production effect, let alone benefit.Do not have a kind of greenhouse to utilize solar energy just can produce winter fully, and to summer, the overheated problem of large greenhouse can't resolve again.Want to solve neither consumes energy, can make plant again, obtain higher benefit, at first will on the Rational structure in design greenhouse, start with at cold normal growth in winter.Have only greenhouse structure reasonable, could save the energy, improved the economic benefit at user and plantation family, also played the good action of preserving the ecological environment simultaneously.

The utility model content

Technical problem to be solved in the utility model provides a kind of solar energy and even strides the greenhouse, this use is even striden the greenhouse at the solar energy of north cold area, be a kind ofly can fully absorb and utilize solar energy in the winter time, the large-scale straddle type energy saving greenhouse that connects of normal growth thermophily plant.

Technical problem to be solved in the utility model realizes by following scheme: solar energy connects strides the greenhouse, the construction orientation sits in the north facing the south, to the west 7 ℃-8 ℃, it is characterized in that: integral body is that a group of two above unit formations is even striden structure, connect and to stride structure and form a unit to be higher than a unit stepped uniformly, one group of arched frame is established in each top, unit, the two ends of arched frame are fixed on the crossbeam, the crossbeam below is by one group of they sup-port, body of wall by upright brick one-tenth 2 skies to 8 skies, 24cm-100cm is thick, the thick styrofoam of body of wall external pasting 5cm-25cm, and lighting angle α is more than 40 °, body of wall height 2m-9.2m, the high 3.6m-10.8m of ridge, unit span 6m-16m, the greenhouse is lower than ground degree of depth 30cm---100cm.

The utility model also comprises following scheme: cover tar sheathing paper quilt and rainproof cotton-wadded quilt on the greenhouse, and be equipped with the electric rolling machine, door, window are housed on the east in greenhouse, the Xi Qiang.

This solar energy connects strides removable single seat greenhouse, two seated greenhouses, the three seated greenhouses of being split into, greenhouse ..., its performance is the same all to be the greenhouse of full solar energy.This greenhouse can be according to northern China physioclimate characteristics and user's productivity requirement, is designed to the performance that different tactic patterns and different greenhouse angles improve the greenhouse in different areas, makes it to reach reasonable use solar energy.

The utlity model has following advantage: one, daylighting in winter is good, because greenhouse lighting angle α in the south is more than 40 °, can make full use of solar energy in the winter time, can make full use of direct sunlight, can make full use of scattered light again.In Winter Solstice--in-the Spring Equinox, the above light of 75%---95% enters the greenhouse, and illumination has been got well, and has also just saved the energy, has protected ecotope.Two, this greenhouse is designed to 24cm---100cm with body of wall, and 2 skies come anti-freezing and heat-insulating to 8 skies in the styrofoam that the body of wall back thick magnesite of subsides 5cm---25cm is made, and the greenhouse wall insulation performance of this spline structure is fine.The winter protection ditch be provided in a side of the greenhouse in the south with brick one-tenth 24cm wide * wallette that 50cm is dark, the wall styrofoam of buried depth 50cm, thick 5cm outward gets final product.The styrofoam of greenhouse thing gable buried depth 50cm, thick 5cm is antifreeze.Three. adopt 3 meters far away wide row space cultivation mode, be equipped with electric roller blind system, it is more simple and convenient to operate, the various vegetables of planting, ventilation and penetrating light is very good, and plant is also just long good.Four, steel roof truss adopts welding antirust paint or two kinds of methods of zinc-plated assembled to design, and both beautiful and practical, the design in whole greenhouse is equal to general greenhouse or is lower than the cost in general greenhouse.

Even stride the greenhouse adopts 7 ° of-8 ° of angles to the west, the daylighting face that sits in the north facing the south to solar energy.Span and height are decided with the user, and body of wall is designed to different thickness with the weather conditions of each department.Lighting angle designs with the geographical position of each department, the difference of weather conditions.Past daylighting angle is generally 23.5 °, and now improving minimum is 40 °, could guarantee entering of illumination heat energy like this, guarantees the needs that produce winter.This solar energy connects that to stride that the greenhouse takes apart be exactly the greenhouse of single seat, and performance all is the same, is more suitable in present stage the using and develop of peasant household, and can both allow plant normal growth in winter.The greenhouse is obducent, and to be improved to a kind of be that brown paper, interior outsourcing one deck plastic foil come rain and snow, another kind be the cotton curtain made of waterproof cloth, in add one deck every freezing foam and one deck waterproof plastic film forms, play heat insulation effect rainproof, snow defence better.

Solar energy connects strides the test of greenhouse by for many years, has overcome all difficulties, now ripe.In the northern area of China the coldest time-30 in winter ℃--in the time of 40 ℃, the indoor temperature fine day can reach more than 30 ℃; Cloudy day reaches more than 20 ℃, remains on night more than 10 ℃.According to plantation plant different cultivars needs, the available morning and evening that puts curtain is adjusted temperature.This solar energy connects strides the greenhouse and belongs to a kind of large greenhouse that need not to heat, and it not only is used for grow seedlings of vegetable and production, can be used for also simultaneously that flowers, fruit tree etc. are macrophytic grows seedlings and produce, and tall and big fruit tree all can be planted in interior.

Description of drawings
