Multi-layer heat-breaking greenhouse roof structure

This creation relates to a roof structure, especially a multi-layer heat-breaking greenhouse roof structure.

The traditional greenhouse roof structure is generally made of black nylon mesh, single-layer crepe board, metal wave board, etc., so that the plants in the greenhouse can open the black shade net in winter to obtain sunlight and warm the greenhouse; however, the modern climate The greenhouse effect and the average temperature are getting higher and higher, causing the temperature of the greenhouse to overheat, causing the plant to be sultry and high temperature, causing growth obstacles or drying up and causing plant death.

At present, in order to avoid too high temperature in the greenhouse, most of the measures are to add cooling equipment such as air-conditioning, water mist or fans in the greenhouse to keep the indoor temperature suitable for growing. However, the installation of such heat-dissipating equipment in the greenhouse will increase the electricity consumption, which has increased the operating cost of the industry, and although the air-conditioning can keep the indoor temperature down, it will cause the outdoor temperature to rise and become a vicious circle.

Therefore, the purpose of the present invention is to provide a multi-layer heat-breaking greenhouse roof structure, so that the greenhouse roof can have the effect of reducing the indoor temperature.

In order to achieve the above object, the present invention provides a multi-layer heat-insulating greenhouse roof structure, which is a laminate comprising two polyurethane foam metal wave plates and a high-density foam layer; The metal wave plates are stacked, and the high density foam layer is disposed between the two polyurethane foam metal wave plates.

Preferably, the multi-layer heat-breaking greenhouse roof structure further comprises a heat insulation blanket disposed between the high-density foam layer and one of the polyurethane foam metal wave plates.

More preferably, the heat insulating blanket is made of aluminum foil and foam.

Preferably, the multi-layer heat-breaking greenhouse roof structure further comprises a plurality of transparent devices, which are spaced apart from the laminate, and the plurality of transparent devices are respectively protruded from the two polyurethane foam metal waves. Relatively two sides.

More preferably, the multi-layer heat-breaking greenhouse roof structure comprises a light-emitting member, and each of the light-emitting members is respectively disposed in each of the light-transmitting devices.

Preferably, the plurality of light transmitting devices are a plurality of solar light source plant lights.

The multi-layer heat-breaking greenhouse roof structure of the present invention combines the polyurethane foam metal wave board, the high-density foam layer and the polyurethane foam metal wave board in order to block the high temperature of the outside direct sunlight, so that the indoor temperature of the greenhouse is not too hot. In addition, the heat insulation blanket can enhance the heat insulation effect of the multi-layer heat-breaking greenhouse roof structure; and the outdoor sunlight can penetrate into the room from the outside of the roof through the light-transmitting device, so that the indoor light is still sufficient; if the plant lighting conditions are insufficient The light-emitting members in each of the light-transmitting devices can open the illumination chamber. Therefore, the creation of the multi-layer heat-breaking greenhouse roof structure can achieve the effect of reducing the indoor temperature of the greenhouse. In addition, it is also possible to provide a sufficient source of light for plant growth photosynthesis and to achieve a planting target that requires light (radiation) heat.

Referring to FIG. 1 and FIG. 2, the multi-layer heat-breaking greenhouse roof structure 10 of the first preferred embodiment of the present invention comprises a laminate comprising two polyurethane foam metal wave plates 11 and a high density. The foam layer 12; the two polyurethane foam metal wave plates 11 are stacked, and the high-density foam layer 12 is disposed between the two polyurethane foam metal wave plates 11.

Referring to FIG. 3, the second preferred embodiment of the present invention is similar to the first preferred embodiment, except that the multi-layer heat-breaking greenhouse roof structure 10 further includes a heat insulating blanket 13, and the heat insulating blanket 13 It is disposed between the high-density foam layer 12 and one of the polyurethane foamed metal wave plates 11. In the embodiment, the heat-insulating blanket 13 is made of aluminum foil and foam.

Referring to FIG. 4, the third preferred embodiment of the present invention is similar to the first preferred embodiment. The difference is that the multi-layer heat-breaking greenhouse roof structure 10 further includes a plurality of transparent devices 14 and the plurality of transparent devices. The 14 series are interposed between the two polyurethane foamed metal wave plates 11 and the high-density foam layer 12, and the two ends of the plurality of transparent light-transmissive devices 14 respectively protrude from the two polyurethane foamed metal wave plates 11 The light-transmitting device 14 is provided with a light-emitting member 141. In the embodiment, the light-transmitting device 14 is a solar light source plant lamp, which can provide light required by the plant to allow photosynthesis of the plant, and the light-emitting member 14 is LED.

According to a third preferred embodiment of the present invention, in the specific application state, the multi-layer heat-breaking greenhouse roof structure 10 is sequentially from the outdoor to the indoor one of the polyurethane foamed metal wave board 11, the high-density foam layer 12 and the other. The polyurethane foamed metal wave board 11 and the outdoor sunlight can be penetrated from the outside of the roof into the room through the light-transmitting device 14, so that the indoor light is sufficient; if the indoor lighting conditions are insufficient, the light-emitting elements 141 in the light-transmitting devices 14 can be Turn on to provide indoor lighting.

The above description is only a preferred embodiment of the present invention, and does not impose any form limitation on the present invention. Although the present invention has been disclosed above in the preferred embodiment, it is not intended to limit the present creation, and has any technical field. In general, the equivalents of the technical solutions disclosed above may be modified or modified to equivalent variations, without departing from the scope of the present invention. Any simple modification, equivalent change, and modification of the above embodiments in accordance with the technical essence of the present invention are still within the scope of the present technical solution.
