Abstract

The utility model discloses a multi-span plastic greenhouse. The greenhouse is of an internal and external double-layer structure, and ceilings of internal and external layers of the greenhouse as well as a plastic-film layer and a sunshade net of a wall body can be opened or closed as required, so that a cooling mode and a heat-preservation mode can be conveniently and freely switched, and two-way temperature control capability of the greenhouse can be greatly improved. Functions are maximized on the basis of less-increased cost, so that the multi-span plastic greenhouse is enabled to be applicable to climatic features in areas of south China especially in areas of Hunan province, and application time of the greenhouse is increased. Meanwhile, on the basis of characteristics of high maintenance of a land utilization rate, a high indoor operation mechanization degree, low energy consumption per unit area, an even indoor spring sowing environment and the like, and the space, of the internal and external layers, in need of heat preservation and cooling is reduced, so that operating cost is lowered.

Description

A kind of Continuous building type plastic tunnel

Technical field

The utility model relates to a kind of Continuous building type plastic tunnel for vegetable growing.

Background technology

China is vast in territory, and weather is complicated, utilizes plastic tunnel to carry out the facility cultivations of vegetables, flowers etc., to alleviating the disparities between supply and demand in vegetables dull seasons, has played special important function, has the huge economic benefit of significant social benefit and reality.Plastic tunnel makes full use of solar energy, heats up obviously, in the situation that technical measures are complete, can utilize plastic tunnel to cultivate in the northern area of China throughout the year.

But in south China area, particularly Hunan area, the overcast and rainy low temperature of winter-spring season, few sunlight, heats difficulty in plastic tunnel; Summer and autumn are hot and humid and dispel the heat badly, and internal-external temperature difference has a strong impact on plant growth above at 10 ℃.In south, particularly under the special climate condition of Hunan area, plastic tunnel only plays the effect of " spring, the autumn was delayed in advance ", the booth vegetable cultivation phase is short, and the most of the time is idle, and availability is low, applicable surface is little, has even produced the tendentiousness suggestion that Hunan area is not suitable for developing facility cultivation.

Continuous building type plastic tunnel refer to span be two across or two across above plastic tunnel, each across between the plastic tunnel that connects by gutter.Its land utilization rate is high, and office operation mechanization degree is high, and unit are energy resource consumption is few, and Indoor Temperature luminous environment is even.

Summary of the invention

In order to solve above-mentioned drawback, technical problem to be solved in the utility model is that a kind of Continuous building type plastic tunnel for vegetable growing that Hunan area is used that is suitable for is provided.In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is, a kind of Continuous building type plastic tunnel, adopt coating steel pipe fabricated construction, it is characterized in that, described booth is interior outer double-layer structure, and ceiling and the body of wall of its inside and outside layer all arrange respectively frame, support respectively inside and outside two layers of plastic rete; Described inside and outside two layers of plastic rete all adopts can rolling or folding structure, realizes and opening wide completely or sealing; Between the inside and outside ceiling of described booth, device can rolling or folding sunshade net.

The beneficial effects of the utility model are, adopt technique scheme, the ceiling of the inside and outside layer of booth and plastic membranous layer and the sunshade net of body of wall can open wide as required or seal, between radiating mode and insulation pattern, freely switch easily, greatly improved the Double-direction Temperature regulating power of booth.On the basis of less increase cost, realized the maximization of function, make it to be adapted to the climatic characteristic in south China area, particularly Hunan area, improve the applicable time of booth.Meanwhile, keeping its land utilization rate high, on the basis of the feature such as office operation mechanization degree is high, and unit are energy resource consumption is few, and Indoor Temperature luminous environment is even, inside and outside bilayer reduces the space of needs insulation or heat radiation, has reduced operating cost.

As a kind of improvement, the internal layer of described booth arranges some partitions that can rolling rete form, and inner space is divided into the separate unit of some mutual sealings.Can use as required wherein certain separate unit, and all not use whole booth.Further cut operating costs.

Below in conjunction with embodiment, the utility model is described in further detail.

Accompanying drawing explanation

Accompanying drawing is the structural representation of the utility model specific embodiment.

Embodiment

Referring to accompanying drawing, reflect a kind of concrete structure of the present utility model, described Continuous building type plastic tunnel across forming, adopts coating steel pipe fabricated construction by three, booth is interior outer double-layer structure, and the ceiling of outer frame 1 and internal layer frame 2 and body of wall support respectively inside and outside two layers of plastic rete; Described inside and outside two layers of plastic rete all adopts can rolling or folding structure, by film-coiling device 5, is realized and being opened wide completely or sealing; Between the inside and outside ceiling of described booth, device can rolling or folding sunshade net 3.Internal layer frame 2 Nei spaces are provided with the partition can rolling rete forming, and in this example, take column 4 and column 6 is boundary, is respectively equipped with two partitions, and putting down can rolling rete, internal layer frame 2 Nei spaces can be divided into three unit of sealing mutually.

The above-mentioned implementation that the utility model is described is only for the technical solution of the utility model is clearly described, and can not be interpreted as the utility model is made to any restriction.The utility model has known multiple substituting or distortion in the art, not departing under the prerequisite of the utility model essential meaning, all falls into protection domain of the present utility model.

Claims

1. a Continuous building type plastic tunnel, adopts coating steel pipe fabricated construction, it is characterized in that, described booth is interior outer double-layer structure, and ceiling and the body of wall of its inside and outside layer all arrange respectively frame, support respectively inside and outside two layers of plastic rete; Described inside and outside two layers of plastic rete all adopts can rolling or folding structure, realizes and opening wide completely or sealing; Between the inside and outside ceiling of described booth, device can rolling or folding sunshade net.

2. a kind of Continuous building type plastic tunnel as claimed in claim 1, is characterized in that, the internal layer of described booth arranges some partitions that can rolling rete form, and inner space is divided into the separate unit of some mutual sealings.
