Greenhouse provided with solar heating system

Abstract

The invention discloses a greenhouse provided with a solar heating system. The greenhouse provided with the solar heating system comprises a greenhouse body and the solar heating system, wherein the solar heating system comprises a coiled pipe which is buried in the ground in the greenhouse body and used for heating soil in the greenhouse body, a first water tank which is connected to the coiled pipe, an irrigating pipeline which is arranged on the ground in the greenhouse and used for irrigating, a second water tank which is connected to the irrigating pipeline, a heating water tank and a vacuum pipe solar heat collector; water in the coiled pipe is treated as a heat transfer medium; the first water tank is connected to the heating water tank through a first valve; the second water tank is connected to the heating water tank through a second valve; the heating water tank is connected to the vacuum pipe solar heat collector. According to the greenhouse adopting the abovementioned structure, the solar energy is utilized for heating water, and the heat is transferred to the soil through the coiled pipe, and warm water is provided for irrigating, so that proper growing temperature is provided to vegetable, and the energy is saved; the problem of the temperature for the growth of fruits and vegetable in winter can be solved without other heat sources such as a furnace; and the output of vegetable is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a greenhouse equipped with a solar heating system. Background technique [0002] Greenhouses are an important part of agricultural facilities. Using greenhouses to cultivate crops (such as vegetables) can promote their early maturity and enrich their yields, and extend the supply period of vegetables. It is an effective way to expand vegetable production and achieve annual supply. In most parts of our country, the winter is severe and long. In winter and spring, when crops cannot grow, it is mainly due to the cold climate and insufficient sunlight in winter, which greatly restricts the production of protected horticulture. At present, the room temperature in the greenhouse is heated by sunlight, and then the heat is supplemented by heat sources such as stoves or radiators to heat the interior of the greenhouse. The soil temperature in the greenhouse is indirectly...
