Vegetable greenhouse capable of automatically removing snow and controlling temperature

Abstract

The invention discloses a vegetable greenhouse capable of automatically removing snow and controlling temperature. The greenhouse comprises a main greenhouse body, and the main greenhouse body comprises an inner greenhouse framework and an outer greenhouse framework which are of arc steel frame structures; light-transmission thin film is laid at the inner side of the inner greenhouse framework, heat preservation film is laid at the outer side of the outer greenhouse framework, heat exchange pipes are laid between the inner greenhouse framework and the outer greenhouse framework, and heat dissipation pipes are provided with heat dissipation sheets. The vegetable greenhouse has the following advantages that heat of the heat exchange pipes is subjected to energy exchange with the greenhouse through the heat dissipation sheets, and therefore the temperature of a heat preservation layer of the greenhouse is changed; the vegetable greenhouse has the function of adjusting the temperature, inwinter, the heat dissipation pipes can be connected with an independent heating boiler or an urban heating system, in hot summer, cool water can be introduced into the heat exchange pipes for heat dissipation and cooling according to demands, and therefore the greenhouse is warm in winter and cool in summer.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a vegetable greenhouse capable of automatic snow removal and temperature control. Background technique [0002] Nowadays, with the development of greenhouse planting technology, people can also eat more and more off-season vegetables in the cold winter. Whether it is in the south or north of China, people basically use greenhouses to grow vegetables in winter, especially in the vast northern regions. Due to the cold weather, the insulation effect of vegetable greenhouses is very important. Vegetable greenhouses can not only produce Good economic benefits, but also provide green food in winter. [0003] However, most of the existing vegetable greenhouses are built with arches and plastic films, which have low stability and insufficient ability to resist wind and snow, resulting in higher maintenance costs. Especially in winter when there is heavy snow, if the snow ...

Problems solved by technology

[0003] However, most of the existing vegetable greenhouses are built with arches and plastic films, which have low stability and insufficient wind and snow resistance, resulting in high maintenance costs.

Especially in winter when there is heavy snow, if the snow on the roof of the shed cannot be cleaned in time, it will cause snow accumulation and the collapse of the shed, causing the destruction of vegetables in the shed. Although people are busy cleaning up when it snows, manpower is limited, especially But at night, they often fail to take care of it and cause losses. This is a difficult problem that people are currently facing when growing vegetables in greenhouses.
