Description

Multi-span greenhouse interior insulation system

technical field

The utility model relates to a multi-span greenhouse, in particular to an inner heat preservation system for a multi-span greenhouse.

Background technique

The multi-span greenhouse is an agricultural facility widely used in northern my country. It is of great significance to the development of modern agriculture. It has become an important scientific and technological project for the development of high-efficiency agriculture in rural areas of our country and the realization of agricultural industrialization. Due to the unique climate and environment in the northern region, coupled with factors such as energy shortages, energy conservation and heat preservation of multi-span greenhouses and reduction of operating costs have become the primary issues restricting the use of multi-span greenhouses for winter production in northern regions. The previous multi-span greenhouse did not install an internal insulation system, resulting in a large amount of heat loss. On the one hand, it will cause a large increase in the operating cost of the multi-span greenhouse. On the other hand, the temperature of the multi-span greenhouse will be low, affecting product quality and causing huge economic losses. The application of the thermal insulation system in the multi-span greenhouse of the utility model makes the above-mentioned problems well solved.

Utility model content

The purpose of the utility model is to provide an inner heat preservation system for improving the heat preservation and utilization efficiency of multi-span greenhouses.

In order to achieve the above object, the technical solution adopted by the utility model is:

An internal thermal insulation system for multi-span greenhouses, comprising a space formed by the steel frame of multi-span greenhouses and the greenhouse surface, and also including plastic films, support curtain lines, and dew-collecting grooves, and the support curtain lines are arranged vertically and horizontally in the space Inside, the dew-collecting groove is embedded in the steel frame of the multi-span greenhouse, and the plastic film is placed on the supporting curtain line and supported by the supporting curtain line.

In order to control the opening and closing of the plastic film, it can be opened during the day and closed at night to form a closed space to achieve the purpose of heat preservation. The heat preservation system in the multi-span greenhouse is also provided with a film roll device.

The utility model has the advantages that: the utility model combines other devices of the greenhouse to improve the thermal insulation of the greenhouse, increase the temperature of the greenhouse by 3-5 degrees, save considerable heating costs, and improve economic benefits.

Description of drawings

Figure 1 is a schematic diagram of the overall structure of the utility model.

Detailed ways

The utility model is described in detail below in conjunction with accompanying drawings. As shown in FIG. Groove 3 is embedded on the steel frame 5 of multi-span greenhouse, and plastic film 1 is placed on the support curtain line 2, is held up by support curtain line 2, so just forms a closed space inside the greenhouse.

In order to control the opening and closing of the plastic film, it can be opened during the day and closed at night to form a closed space to achieve the purpose of heat preservation. The heat preservation system in the solar greenhouse is also provided with a film rolling device 4 .

The plastic film can adopt domestic high light transmittance, high-quality film.

Common products can be used for the film roll and the curtain line.

Claims (2)
