Technical Field

The invention relates to a heat-insulation greenhouse in an interlayer greenhouse, and relates to the field of agricultural building facilities.

Background

In the modern agricultural planting process, in order to improve the planting efficiency of some crops, a greenhouse planting technology is invented, and the method is a scientific planting mode.

The existing plastic greenhouse can utilize solar energy, has a certain heat preservation effect, adjusts the temperature and humidity in the greenhouse within a certain range through a rolling film, is a greenhouse with a non-heating single-span arch roof structure and takes a plastic film as a covering material, the light transmittance is generally 60% -75%, in order to ensure the basic balance of the average illumination all day, the planar layout of the greenhouse is mostly in a form of prolonging the north and south, the greenhouse in the prior art is easy to construct, convenient to use and low in investment, and is a simple and easy protected cultivation facility. The semi-arch round type greenhouse is developed quickly in Heilongjiang, Liaoning, Jilin, Shandong and other provinces, the wall is built on the north side, the arch frame is arranged on the south side, the semi-arch round type greenhouse is in a semi-arch round shape, is equivalent to a sunlight greenhouse in Beijing area, has good lighting, heat preservation and wind resistance, is convenient to heat, and can be used for seedling raising, seedling separation or direct cultivation, but the existing greenhouse has the defects that the indoor temperature can not be kept for too long time, and the heat preservation time effect is general.

Disclosure of Invention

The invention aims to provide a heat-insulation greenhouse in an interlayer greenhouse, which can reach 45-55 ℃ at most under the condition of sufficient illumination in the daytime, is higher than the temperature outside the greenhouse by more than 25 ℃, has poor temperature increasing effect on rainy days, and has the lowest temperature inside the greenhouse which is 10-13 ℃ higher than the temperature outside the greenhouse at night. The ground temperature in the shed is stable compared with the air temperature, and is usually 13-23 ℃.

In order to achieve the purpose, the invention adopts the following technical scheme: it contains outer big-arch shelter membrane 1, inlayer big-arch shelter membrane 2, greenhouse skeleton 3, heat preservation interlayer 4, mounting groove 5, and mounting groove 5 sets up in 3 lower floors of greenhouse skeleton, and outer big-arch shelter membrane 1 is connected with 3 upper strata of greenhouse skeleton, and inlayer big-arch shelter membrane 2 is connected with mounting groove 5, and outer big-arch shelter membrane 1, inlayer big-arch shelter membrane 2 connect through greenhouse skeleton 3 and form heat preservation interlayer 4.

Furthermore, the outer layer of the greenhouse film 1 is made of environment-friendly plastic.

Further, the inner layer of the greenhouse film 2 is made of environment-friendly plastic.

Furthermore, the greenhouse framework 3 is made of iron pipes.

Further, the mounting groove 5 is of a dovetail groove structure.

Furthermore, the width of the heat-insulating interlayer 4 is 10 cm-100 cm.

The working principle of the invention is as follows: solar radiation passes through outer big-arch shelter membrane 1 very easily, inlayer big-arch shelter membrane 2, and the plastic film conductivity is very poor, cause the heat to hardly give off through plastic film outwards, this is exactly the effect that thermal-insulated heat preservation 4 plays, because the heat hardly passes through outer big-arch shelter membrane 1, inlayer big-arch shelter membrane 2 outwards runs off, cause the inside upper and lower difference in temperature of big-arch shelter to be unable the expansion, just also make the convection current very little, so can keep warm, add heat preservation interlayer 4 in the big-arch shelter, one deck or multilayer make the heat preservation big-arch shelter when there is not sunshine, night, cloudy day, when sleet al, the falling speed of temperature in the slow down canopy, thereby improve temperature 5 ~ 35 ℃ in the big-arch shelter, reach energy saving and emission reduction's effect.

The design principle and the production principle of the greenhouse are basically the same as the heating process of the atmosphere. Greenhouse greenhouses are almost "transparent" to solar radiation, which can mostly enter. However, greenhouses and glass are not "transparent" to ground long wave radiation, which is less transparent. Therefore, the greenhouse and the greenhouse enable external solar energy to continuously enter the room, indoor heat is rarely dissipated, the temperature is adjusted, and the higher the overall height of the greenhouse is, the better the heat preservation effect is.

After the technical scheme is adopted, the invention has the beneficial effects that: the heat-insulating greenhouse in the interlayer greenhouse has one or more layers of heat-insulating interlayers, so that the internal temperature of the greenhouse can be increased, the temperature reduction speed is reduced, and the heat-insulating time is long.
