Clean heating system for greenhouse

Abstract

The invention relates to the technical field of greenhouse heating, in particular to a clean heating system for a greenhouse. The clean heating system for the greenhouse comprises a base and the greenhouse, and further comprises a controller, a solar heat collector, a heat preservation box, a heating mechanism, a lead-in mechanism and a pushing mechanism, the heating mechanism is arranged at the bottom of the inner side of the greenhouse, and the heating mechanism comprises a support frame and a heat supply assembly, the lead-in mechanism is arranged between the greenhouse and the heat preservation box and comprises an extraction pipe and an energy storage assembly, the pushing mechanism is arranged on the side of the lead-in mechanism and comprises a conveying pipe, a traction assembly and an overturning assembly, the conveying pipe is fixedly arranged on the top of the inner side of the greenhouse, the overturning assembly is arranged on the side of the conveying pipe the traction assembly is arranged between the energy storage assembly and the overturning assembly, and the heat preservation box is electrically connected with the controller. The clean heating system for northern greenhouse is high in speed, good in effect, capable of moistening crops and promoting the growth of the crops, lower in energy consumption and beneficial to reducing the heating cost.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to a clean heating system for greenhouses. Background technique [0002] Greenhouses and seedling sheds are problematic for plant growth or survival due to the cold weather in northern regions. In the past, we basically relied on burning coal, but due to environmental protection requirements, coal is basically banned, and the energy consumption is only electricity or gas. Gas is almost unrealistic, and gas pipelines are difficult to reach farmland. [0003] my country's patent application number: CN201711076778.0; publication date: 20190514 discloses a greenhouse heating device for agricultural planting, including: a heating furnace body, an electric heater, a cold air pipe, a blower, an air outlet pipe, and a temperature sensor; the cold air pipe Set on one side of the heating furnace body, the blower is set on the cold air pipe; the air outlet pipe is set on the upper end of th...

AI Technical Summary

Problems solved by technology

[0006]1. When heating the greenhouse, usually only the leaves of the crops inside can be heated, and the roots buried under the soil can obtain less heating benefits. The speed is slow, which is not conducive to the growth and development of crops. Therefore, the heating effect needs to be improved

[0007]2. Use electric energy to realize heating, which consumes a lot of energy, which is not conducive to reducing heating costs

[0008]3. The heating method is relatively single, and the temperature rise inside the greenhouse is slow, so it is impossible to achieve rapid heating, and the heating efficiency needs to be improved

[0009]4. The heating medium cannot be recycled, which is not conducive to resource saving
