Insulation system and working method for greenhouse

Abstract

The invention relates to a thermal-insulation system in a greenhouse and a working method of the system. Greenhouse steel frame rails, thermal-insulation quilts and an information control device are arranged in a greenhouse body; a transmission shaft is arranged at the top ends of the greenhouse steel frame rails, fixed pulleys are arranged at the bottom ends of the greenhouse steel frame rails, movable pulleys are arranged on the rails and fixedly connected with the thermal-insulation quilts, a transverse rod is connected to the tail ends of the thermal-insulation quilts, one end of each transmission rope is connected with the transverse rod, the other end of each transmission rope is wound around the transmission shaft by bypassing the corresponding fixed pulley and then is connected with the transverse rod, the transmission shaft is connected with a motor, and when the transmission shaft rotates to roll up the transmission ropes, the transverse rod is pulled by the transmission ropes so that the thermal-insulation quilts can be opened or closed. According to the internal thermal-insulation system, on the basis of an information control center composed of temperature sensors and integrated control cabinets, temperature can be accurately adjusted, the original mode that temperature is adjusted according to the experience of personnel is changed, and automatic opening and closing are performed through information control; through the internal thermal-insulation system, aging, deviation and light transmittance decrease of a thin film caused by external thermal insulation can be effectively avoided.

Description

technical field [0001] The invention relates to a thermal insulation system in a greenhouse and a working method thereof, belonging to the technical field of agricultural greenhouses. Background technique [0002] At present, the existing thermal insulation methods for cultivation in greenhouse facilities are mainly external covering insulation. The traditional method is to cover the outer surface of the greenhouse with thermal insulation materials. Thermal insulation materials generally include straw thatch, cattail mats, paper quilts and cotton quilts. The material covers the outside of the film of the greenhouse. Their common disadvantages are that they are bulky, labor-intensive and labor-intensive to roll and unwind. After being soaked by rain and snow, it not only increases their own weight, but also reduces the thermal insulation performance, and seriously pollutes the film, which is easy to reduce. Transmittance. [0003] In recent years, greenhouse facilities in so...

AI Technical Summary

Problems solved by technology

[0008] 1) The overall structural design is complex, inconvenient to install and use, and not conducive to later maintenance;

[0009] 2) The cost of greenhouses in the form of internal insulation is high, and it cannot be widely used;

[0010] 3) The structure with internal insulation design occupies the inner space of the greenhouse, which is easy to affect the internal operation of the greenhouse;

[0011] 4) Using the form of internal heat preservation to adjust the internal temperature of the greenhouse relies on personal experience to open and close the inner heat preservation layer. The timing of opening and closing the heat preservation layer is unscientific, and the temperature inside the greenhouse cannot be precisely controlled;
