Saving greenhouse

 

(57) Abstract:

The invention relates to a device for crop production in greenhouses. The rotary plate made of a transparent material that transmits ultraviolet radiation and resistant to the effects of precipitation, and in the upper part of the greenhouse directly below the deflection plates of the roof at its parts installed drums with a driving mechanism and a wound on them opaque and reflective film element and the ability to scroll from one drum to another. This provides an optimal microclimate at any time of the year, improving the reliability of resource-saving greenhouses, reducing its cost and operating costs. 1 Il.

The invention relates to a device for crop production in greenhouses.

Known devices closest to the technical essence is energy-efficient greenhouse containing the Foundation, base, stand, farm, film element, the roof and side walls in the form of a set of rotating plates, the actuator opening / closing roof (see nab the/P> The disadvantage of this greenhouse is the presence of a complex automated system for tracking the position of the sun, including sensors, actuators, power supply system. This reduces the reliability of the system increases its cost increases operating costs.

The objective of the invention is to improve the reliability of resource-saving greenhouses, reducing its cost and operating costs.

The above technical result is achieved in that the rotary plate made of a transparent material that transmits ultraviolet radiation and resistant to the effects of precipitation, and in the upper part of the greenhouse directly below the deflection plates of the roof at its parts installed drums with a driving mechanism and a wound on them opaque and reflective film element and the ability to scroll from one drum to another.

The invention is illustrated by the drawing, which shows a General view of resource-saving greenhouses.

Saving greenhouse consists of a film of item 1, roof 2, side walls 3, the rotary plate 4, the actuator 5 opening and closing the roof and resistant to the effects of precipitation, and in the upper part of the greenhouse directly below the deflection plates of the roof 2 in the extreme parts installed drums 6 with a drive mechanism 7 and is wound on them opaque and reflective film element and the ability to scroll from one drum to another. In the inner space of the greenhouse is placed lamp 8.

Saving greenhouse works as follows.

The first mode. The rotary plate 4 closes the roof 2, and opaque and reflective film element 1 is located under the rotary plate 4.

The second mode. The rotary plate 4 open the roof 2, and opaque and reflective film element 1 is rolled on the reel 6.

The third mode. The rotary plate 4 closes the roof 2, and opaque and reflective film element 1 is rolled on the reel 6.

The fourth mode. The rotary plate 4 open the roof 2, and opaque and reflective film element 1 is located under the rotary plates 2.

All modes can be obtained by means of the actuator 5 and the drive mechanism 7.

The first mode is used when neobhodimymi cold at night time.

The second mode is used when it is necessary to use natural radiation heat fluxes and precipitation, while saving resources for their artificial receipt. Used in the daytime during the warmer months.

The third mode is used when it is necessary to avoid overheating of plants and "dump" the excess heat, and when the weather is unfavorable for plants, for example, are plentiful rains and there is a danger of waterlogging of the soil.

The fourth mode is used when it is necessary to avoid overheating of the plants, but it is necessary to limit the duration of day length and excess natural radiation, such as sowing of radish, some types of flowers, etc.

Thus, the proposed resource-saving greenhouse to the maximum extent allows to save resources, using natural factors (irrigation, artificial and natural warmth), and at the same time to provide the best mode for normal development of plants. In the warmer months we offer a greenhouse retains all the advantages of open ground and all the benefits of a protected ground under adverse climatic characteristics and weather conditions.

Resursele set the rotary plate, the actuator opening and closing of the roof, characterized in that the rotary plate made of a transparent material that transmits ultraviolet radiation and resistant to the effects of precipitation, and in the upper part of the greenhouse directly below the deflection plates of the roof at its parts installed drums with a driving mechanism and a wound on them opaque and reflective film element and the ability to scroll from one drum to another.
