Technical Field

[0001] This utility model belongs to the technical field of greenhouse roller shutter structure, specifically a roller shutter structure for greenhouses. Background Technology

[0002] A greenhouse roller shutter structure is a common device used to roll up the insulation layer of a greenhouse. In winter, especially after rain or snow, the insulation structure absorbs rainwater, and when the temperature drops below zero, it freezes. If the roller shutter structure is used at this time, the ice crystals may damage the plastic greenhouse. To avoid this situation, this application proposes a greenhouse roller shutter structure. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a greenhouse roller shutter structure, which effectively solves the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a greenhouse roller shutter structure, including an insulation pad and a roller shutter shaft. The insulation pad has a heat-conducting structure inside, and there are multiple heat-conducting structures arranged parallel to each other inside the insulation pad. One end of the heat-conducting structure extends outside the insulation pad, and all heat-conducting structures are connected to a connecting line, which can be wound around the roller shutter shaft.

[0005] Preferably, a protrusion is fixedly connected to the roller shutter shaft, and the connecting wire is wound around the protrusion.

[0006] Preferably, the distance between adjacent heat-conducting structures is 30-50 cm.

[0007] Preferably, the heat-conducting structure includes a heating layer, a heat-conducting enhancement layer, a waterproof layer, and a flexible protective layer arranged sequentially from the inside out.

[0008] Preferably, the heating layer is electrically heated and its material is nickel-chromium alloy; the thermally conductive reinforcing layer is made of thermoplastic polyurethane; the waterproof layer is made of polyurethane film; and the flexible protective layer is made of silicone layer or nylon coating layer.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] When ice forms on the insulation pad, in order to prevent the ice fragments from damaging the plastic greenhouse, the heat-conducting structure is connected to the external circuit, which causes the heat-conducting structure to heat up and melt the ice fragments on the insulation pad. The evenly distributed heat-conducting structure can heat the entire insulation pad. Attached Figure Description
