Abstract
The utility model relates to a geotherm utilizing device for increasing farmland temperature, which comprises an air inlet pipe and an air outlet pipe, wherein the air inlet pipe and the air outlet pipe extend into an underground thermal layer. The geotherm utilizing device is characterized in that a connecting pipeline or a connecting container for heating air is arranged between the air inlet pipe and the air outlet pipe which extend into the underground thermal layer. The device utilizes chimney effect to extract underground thermal energy for heating air, so that environmental temperature of crops on the earth's surface is increased. In addition, the geotherm utilizing device is not only simple in structure and low in manufacture cost, but also energy-saving, emission-reducing and environment-friendly.
Description
Technical field
The utility model relates to a kind of geothermal utilization device that improves the farmland temperature.
Background technology
China's weather mainly be: complicated and diversified weather helps the growth of various plants and crops, for China provides abundant animal and plant resource; China's monsoon climatic region is vast, summer high temperature, and rain is favourable to growth and the maturation of crops, trees, herbage the hot same period; But going down south owing to cold air in the time of in the winter time, the plant growing and the harvest in a lot of zones are all bad, for the anti-season crops are cultivated in the harvest and the plantation that improve the crops in winter, the greenhouse is praised highly by numerous working people, but because the thermal source problem (normally in the greenhouse, adding equipment such as warming and humidifying machine) in greenhouse, make greenhouse culture expense especially costliness, unfavorable promoting the use of.
Summary of the invention
The purpose of this utility model is to provide a kind of geothermal utilization device that improves the farmland temperature, this device utilizes stack effect to extract underground heat energy, be used to add hot-air, improve the environmental temperature of face of land crops, the utility model is not only simple in structure, low cost of manufacture, and energy-saving and emission-reduction, environmental protection.
Of the present utility model being characterised in that: a kind of geothermal utilization device that improves the farmland temperature, comprise the air inlet pipe and the blast pipe that stretch into underground thermosphere, it is characterized in that: described at underground thermosphere air inlet pipe and blast pipe between be provided with the connecting line that is used for heated air or connect container, the height that the height that described air inlet pipe elevates above the soil elevates above the soil less than blast pipe.
In order to add strong convection, the caliber of above-mentioned air inlet pipe is greater than the caliber of blast pipe, and described connecting line is the spiral connecting line.
In a preferred embodiment, above-mentioned air inlet pipe and blast pipe all are arranged in the greenhouse, and when the temperature in the greenhouse was badly in need of raising suddenly, the pipeline that above-mentioned air inlet pipe elevates above the soil was provided with fan blower, after utilizing fan blower that air is blown to underground heating, be recycled in the greenhouse.
Advantage of the present utility model: the one, this improves geothermal utilization device simple in structure of farmland temperature, and low cost of manufacture helps reducing the fund input of arviculture, improves peasant's income; The 2nd, utilize " stack effect ", that is: the height that elevates above the soil less than blast pipe of the height that elevates above the soil of air inlet pipe, make gas after being heated can free convection to the face of land, need not other equipment and also can realize; The 3rd, when need should be acute the raising greenhouse in temperature the time, can utilize fan blower that air inlet pipe is blown, improve cross-ventilated speed, the fast rise of temperature in the realization greenhouse.
