Agricultural greenhouse capable of precisely controlling temperature

Abstract

The invention provides an agricultural greenhouse capable of precisely controlling temperature. A support is installed in a greenhouse body, an air-permeable layer is installed on the lateral wall ofthe greenhouse body, the top of the support is fixedly provided with a main channel, an air inlet channel is inserted into the bottom of the main channel, heating channels are inserted into the two sides of the air inlet channel, and an air valve is arranged on the bottom of the air inlet channel. A box body is put at the bottom of the support, the top of the box body is fixedly provided with a liquid condensing tank, a liquid discharging channel is inserted into the side wall of the liquid condensing tank, and an air discharging channel is inserted into the bottom of the liquid condensing tank. A top cover is installed on the top of the liquid condensing tank, the top of the top cover is connected with a connecting rod, a supporting rod is hinged to one end of the connecting rod, and thetop of the supporting rod is fixedly installed on the bottom of the air valve through a bolt. In the device, evaporative condensation of C4-C6 fractions serves as a controller for controlling the temperature of the greenhouse, labor is saved, and the change of the temperature difference in the greenhouse is smaller.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouses, in particular to an agricultural greenhouse capable of precise temperature control. Background technique [0002] Agricultural greenhouse is a frame-covered structure with excellent thermal insulation performance. It appears that people can enjoy off-season agriculture. Generally, agricultural greenhouses use bamboo or steel structure skeletons, covered with one or more layers of thermal insulation plastic film. , In this way, a greenhouse space is formed, and the outer film can well prevent the loss of carbon dioxide produced by the internal agricultural growth, so that the shed has a good heat preservation effect. In the use of agricultural greenhouses today, the greenhouses are basically in a closed state, which makes the ventilation effect inside the greenhouses extremely poor. If you do not pay attention to controlling the temperature of the greenhouses, the temperature insi...

Problems solved by technology

In the use of agricultural greenhouses today, the greenhouses are basically in a closed state, which makes the ventilation effect inside the greenhouses extremely poor. If you do not pay attention to controlling the temperature of the greenhouses, the temperature inside the greenhouses will be too high, which is not conducive to the growth of agriculture. Traditional manual supervision is inefficient. , there are too many mechanical operations, and with the rise of labor costs, it is no longer suitable for the development of the new era
