Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, specifically to a heat-insulating structure for the root of a greenhouse. Background Technology

[0002] Greenhouses are widely used for the cultivation or seedling raising of vegetables, flowers, trees and other plants because they have the advantages of regulating environmental conditions such as temperature, humidity and light, and can withstand natural disasters such as wind, rain, hail and frost, thus meeting the diverse needs of the market.

[0003] Greenhouses mainly include plastic greenhouses and glass greenhouses. Except for their lower cost, plastic greenhouses are far inferior to glass greenhouses in other aspects. The smooth surface of glass results in low light scattering and more uniform light distribution inside, reducing uneven growth of crops caused by light differences.

[0004] Glass greenhouses are further divided into ordinary glass greenhouses and double-glazed greenhouses. The heat transfer coefficient of double-glazed glass is as low as 2.0-3.0 W / (m²・K), which is lower than the heat transfer coefficient of single-glazed glass of 5.0 W / (m²・K). In winter, it can reduce heat loss and lower heating energy consumption. In summer, with the help of external shading systems (shading rate of 70%-80%) and ventilation equipment, the indoor temperature can be effectively controlled and high temperature stress can be avoided.

[0005] However, common greenhouse insulation measures mainly focus on the top and sides of the greenhouse structure. While these measures can reduce heat loss from the greenhouse to the outside to some extent, insufficient attention is paid to the insulation of the area where the roots of the greenhouse are in contact with the ground. The roots of the greenhouse are usually directly connected to the outside soil, and the low temperature of the soil will continuously carry away heat from the greenhouse through heat conduction, forming a thermal bridge effect. This heat loss is particularly pronounced at night when the outside temperature is low, causing the temperature inside the greenhouse to drop rapidly. This necessitates frequent operation of heating equipment to maintain the temperature, which not only increases production costs but may also adversely affect crop growth due to large temperature fluctuations. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model designs a root insulation structure for greenhouses, comprising: a support platform, a greenhouse steel structure, thermally broken glass, insulation components, and a cushion layer; the greenhouse steel structure is installed on the support platform; the thermally broken glass is installed on the greenhouse steel structure; the support platform is located within the soil layer; the cushion layer is located above the support platform and is connected to the soil layer; the insulation components are arranged around the outside of the support platform and between the thermally broken glass and the support platform.

[0007] Preferably, the insulation component includes: a first insulation component and a second insulation component; the first insulation component is disposed on the outer side of the foundation; the second insulation component is disposed between the thermally broken glass and the foundation.

[0008] Preferably, the second insulation component includes: a first insulation layer and a second insulation layer; the first insulation layer is disposed between the heat-insulating glass and the support platform, with its top attached to the greenhouse steel structure and its bottom attached to the support platform; there are two second insulation layers, which are respectively disposed on both sides of the first insulation layer and connected to the padding layer.

[0009] Preferably, a sealing element is provided between the heat-insulating glass and the second insulation layer.

[0010] Preferably, the pier includes: a pier body, a reinforcing cage, and embedded bolts; both the reinforcing cage and the embedded bolts are pre-installed inside the pier body, wherein the embedded bolts extend to the outside of the pier body; the greenhouse steel structure is installed on the pier body via the embedded bolts.

[0011] Preferably, the foundation also includes: a post-cast foundation; the greenhouse steel structure is installed on the foundation body with adjustable height via pre-embedded bolts; the post-cast foundation is cast between the greenhouse steel structure and the foundation body.

[0012] Preferably, the greenhouse steel structure includes: steel structural columns and steel structural beams; the steel structural columns are installed on the support platform; the top of the insulation component, which is set between the thermally broken glass and the support platform, is attached to the steel structural beams.

[0013] Compared with the closest existing technology, the beneficial effects of this utility model are as follows: 1. By setting up insulation components, the first insulation component surrounds the outside of the support platform and the second insulation component fills the gap between the heat-insulating glass and the support platform, a closed insulation barrier is built between the root of the greenhouse and the external soil, directly cutting off the heat conduction path between the inside and outside of the greenhouse, eliminating the thermal bridge effect at the root of the traditional greenhouse. Compared with greenhouses without root insulation, the heat loss rate in the root area is reduced by more than 60%, reducing heat loss in the greenhouse from the source.

[0014] 2. The second insulation component of this utility model is designed as a layered structure consisting of a first insulation layer and a second insulation layer set on both sides of the first insulation layer. The second insulation component forms a composite insulation system. When the outside temperature is low at night, it can effectively block the heat leakage from the greenhouse through the roots, reduce the use of heating equipment, and significantly reduce energy consumption.

[0015] 3. The post-cast support structure of this utility model allows the greenhouse steel structure to be installed on the support body with adjustable height via pre-embedded bolts. The post-cast support structure is then cast between the greenhouse steel structure and the support body. The post-cast support structure also ensures the stability of the greenhouse steel structure and makes the installation accuracy controllable. It breaks through the rigidity limitations of traditional fixed connections, avoids hidden dangers such as greenhouse film tearing and stress concentration caused by structural misalignment, and greatly improves assembly accuracy.
