Novel solar greenhouse internal heat preservation device

Abstract

The invention relates to a novel solar greenhouse internal heat preservation device which comprises a greenhouse, a horizontal heat preservation quilt, a side heat preservation quilt, a plurality of heat preservation quilt supporting devices and a driving device, wherein each heat preservation quilt supporting device comprises a cableway fixing device, a heat preservation quilt supporting cableway and a driven shaft; the driving device comprises a horizontal heat preservation quilt driving shaft, a horizontal heat preservation quilt driving motor, a side heat preservation quilt driving shaft, a side heat preservation quilt driving motor and a motor sliding way; and the solar greenhouse inner heat preservation device is further provided with a control system. According to the device, two sets of heat preservation quilts are synchronously retracted, released and stretched through winding of different combinations of multiple steel wire ropes and different winding directions of the steel wire ropes on different transmission shafts. During working, the motors are controlled to rotate cooperatively through buttons, a power shaft achieves the heat preservation function in the sunlight greenhouse through rolling of a reel, the whole working process is efficient and simple, and operation by people is facilitated.

Description

technical field [0001] The invention relates to the technical field of retractable heat preservation quilts for solar greenhouses, in particular to a novel heat preservation device for solar greenhouses. Background technique [0002] The thermal insulation system of the solar greenhouse can be divided into two parts: the thermal insulation enclosure structure and the thermal insulation quilt. Among them, the insulation quilt plays an important role in reducing the heat transfer inside and outside the greenhouse and increasing the temperature in the greenhouse. [0003] At present, there are many types of internal heat preservation devices on the market. However, the current manufacturing technology of the inner heat preservation device is not yet mature, and the inner heat preservation device often has many defects. Danger. Moreover, due to the uneven force on the reel, after a period of use, the reel will be tilted and needs to be adjusted frequently, and it will be repl...

AI Technical Summary

Problems solved by technology

[0004]Aiming at the problems existing in the northern asymmetrical solar greenhouse thermal insulation device, instead of the traditional external thermal insulation method, a thermal insulation quilt is designed from the inside and can be freely retracted. The heat preservation device is placed to solve the problem of the heavy burden on the greenhouse caused by the long-term exposure of the traditional heat preservation to the outside, soaked in rainwater and sun exposure, and the service life of the heat preservation is seriously shortened. The way of heat preservation from the inside can effectively solve such problems, so we design a The new thermal insulation device in the solar greenhouse will play a very important role in the development of the greenhouse in northern my country
