Cleaning and heating system for northern greenhouses

Abstract

The invention belongs to the technical field of heating, and particularly relates to a cleaning and heating system for northern greenhouses. The cleaning and heating system comprises a plurality of planting frames arranged in reserved soil pits of the greenhouses, planting pits are arranged in the planting frames, track grooves and movable awnings are arranged on the planting frames, the movable awnings movably cover the planting pits through the track grooves, a water tank is arranged below the planting pits, the bottom of the water tank slightly inclines towards one end, the same heating system is arranged outside the multiple planting frames, and the heating system supplies heat in a fuel combustion mode and is in communication with the water tank and the movable awnings. The system has the advantages that the system can be suitable for planting in greenhouses with various areas, and especially for heating of greenhouses with ultra-large areas, and temperature regulation and control can be rapidly carried out while energy can be effectively saved.

Description

technical field [0001] The invention belongs to the technical field of heating, and in particular relates to a clean heating system for northern greenhouses. Background technique [0002] With the emergence of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan and European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results; fruit tree production is used to cultivate grapes, strawberries, watermelons, melons, peaches and citrus, etc.; forestry production. It is used for raising seedlings of forest trees, cultivating ornamental trees, etc.; it is used for raising silkworms and chickens in the breeding industry. [0003] The main function of the greenhouse is to adjust the temperature to cope with different climates, so that it can be adjusted to a suitable environment for a long time in many unsuitable c...

AI Technical Summary

Problems solved by technology

[0003] The main function of the greenhouse is to adjust the temperature to cope with different climates, so that it can be adjusted to a suitable environment for a long time in many unsuitable climates, especially in the areas where the climate is too cold in the north. As the temperature increases, the temperature regulation effect will gradually decrease, especially at night without light, the heat preservation effect will also gradually decrease, and at the same time, a lot of energy will be wasted when the area is too large for heating.
