Problems solved by technology

At present, some areas use solar energy or boilers to heat the water temperature, and lay pipes in the cultivation layer to increase the temperature, but these methods have certain defects: solar heating water temperature must be effective in sunny weather, and it has no effect in cloudy, rainy and snowy weather, while cloudy, rainy and snowy weather It is the critical time when it is urgent to increase the ground temperature; boiler heating water temperature must consume a lot of coal or electric energy, which is not conducive to environmental protection
Solar energy or boiler heating water temperature must have circulation systems such as water pumps, which also need to consume electric energy

Embodiment Construction

[0025] This embodiment is to facilitate the understanding of the present invention without limiting the claims and core content of the present invention in any way.

[0026] Examples such as figure 1 and figure 2 As shown, a solar greenhouse that actively utilizes geothermal energy includes a back wall, a gable wall, a cultivation bed 1, a slope at the front foot, a scaffold and a shed film. The cultivation bed 1 is located 0.5-1m below the ground level; the bottom of the cultivation bed 1 is buried There are several tubular conduction parts 3 used to transmit the deep ground temperature to the soil cultivation layer. The tubular conduction parts 3 are vacuum-encapsulated metal cylindrical tubes, 6.5m long and 10cm thick, which contain low-boiling, volatile liquids. One end of part 3 is an evaporation end, and the other end is a condensation end; the tubular conductive part 3 is buried vertically directly below the cultivation ridge 2, the evaporation end of the tubular cond...

Abstract

The invention discloses a terrestrial-heat actively-used solar greenhouse which comprises a rear wall, a gable wall, a cultivation bed, a front footing slope, a greenhouse frame and a greenhouse film. The cultivation bed is lower than the ground plane. A plurality of tubular conduction pieces are embedded in the cultivation bed and vertically embedded right below cultivation ridges. One tubular conduction piece is embedded at the southernmost end of each cultivation ridge, and the other tubular conduction pieces are sequentially and northwards embedded at a 2-m interval. By means of the terrestrial-heat actively-used solar greenhouse, the ground temperature is easily raised, and the low temperature environment in the solar greenhouse in winter and spring with the low temperature is improved.

Description

technical field [0001] The invention relates to a solar greenhouse, in particular to a solar greenhouse that actively utilizes geothermal energy, and belongs to the technical field of vegetable cultivation. Background technique [0002] A solar greenhouse is an agricultural facility that uses solar energy to store and release natural heat. In the low temperature season in winter and spring, low ground temperature is a common defect in traditional solar greenhouses. How to increase the ground temperature is a technical issue that people pay close attention to. At present, some areas use solar energy or boilers to heat the water temperature, and lay pipes in the cultivation layer to increase the temperature, but these methods have certain defects: solar heating water temperature must be effective in sunny weather, and it has no effect in cloudy, rainy and snowy weather, while cloudy, rainy and snowy weather It is the critical time when there is an urgent need to increase the ...
