Abstract

The utility model discloses an agricultural greenhouse lighting device for cultivation, comprising an upper layer plastic film 1 and a lower layer plastic film 1, a mutually parallel compound wire 2 causes the upper plastic film 1 and the lower layer plastic film 1 to be combined into integration along the long direction of the plastic films every distance, and a framework member 3 is penetrated between the upper plastic film 1 and the lower layer plastic film 1. When the utility model is laid, the framework member is unfolded, and the upper plastic film and the lower layer plastic film and are also unfolded and positioned and are separated by air. The utility model has the advantages of good heat insulating effect, no dew, high wind preventing intensity, pressed film saving and convenient use.

Description

The greenhouse lighting device

The utility model relates to agricultural, the used green house of aquaculture field, particularly a kind of greenhouse lighting device.

The greenhouse lighting device all is to constitute so basically at present, on the body of wall of chamber face, take earlier and build frame member, on frame member, lay plastic film then, and then plastics are pushed down with press mold material (as steel pipe, wooden rafter, bamboo bar, film-pressing line etc.), use an inconvenience, two waste the press mold material, and three wind resistances, rain, snow intensity are hanged down bad easily, four the more important thing is, the plastic film internal layer dewfall serious heat-insulating property of dripping is poor.

The purpose of this utility model is to overcome above-mentioned defective, and a kind of press mold material of both having saved is provided, and intensity is high again, can prevent again that plastic film internal layer dewfall from dripping, good heat insulating, greenhouse lighting device easy to use.

Scheme of the present utility model is as follows:

A kind of greenhouse lighting device comprises transparent plastic film 1, and plastic film 1 has two-layer up and down, along its recombination line that is parallel to each other 2 that vertically whenever keeps at a certain distance away, makes upper and lower two layers of plastic thin films 1 integrator.

The spacing of recombination line 2 is more than or equal to 50cm, smaller or equal to 100cm.

Be installed with several frame members 3 in the middle of the upper and lower two layers of plastic thin films 1, its material is steel pipe, bamboo bar and so on.

The utility model has been owing to adopted said structure, and air insulated between the double-layer films can prevent effectively that dewfall from dripping, and has improved heat-insulating property simultaneously; Because frame member is through in it, has both saved the press mold material, has improved bulk strength again, and is also more easy during laying, thereby reached the purpose of this utility model.

Make a more detailed description by embodiment below in conjunction with attached Fig. 1 and 2.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a user mode schematic diagram of the present utility model.

Embodiment:

Present embodiment is so concrete enforcement:

1. two layers of plastic thin films is overlapped up and down, the alignment of four limits is cut out to certain-length according to the green house specification;

2. with heating or stitching devices double-layer films is given compoundly along the every interval 50-100cm of film vertical parallel direction, making up and down, two layers of plastic thin films is integrated;

3. frame member 3 is through between the upper and lower two layers of plastic film according to recombination line 2 spacing distances are close or thin.

4. when laying frame member 3 is deployed in the then upper and lower two layers of plastic thin films of greenhouse roofing, launches thereupon, its interlamellar spacing equals the frame member diameter.

Claims

1. a greenhouse lighting device comprises transparent plastic film (1), and it is two-layer up and down to it is characterized in that plastic film (1) has, and along its recombination line that is parallel to each other (2) that vertically whenever keeps at a certain distance away, makes upper and lower two layers of plastic thin films (1) integrator.

2. greenhouse lighting device according to claim 1, the spacing that it is characterized in that recombination line (2) is more than or equal to 50cm, smaller or equal to 100cm.
