Sectional rolling curtain type internal heat preservation device for solar greenhouse

Abstract

The invention relates to a sectional rolling curtain type internal heat preservation device for solar greenhouse.The sectional rolling curtain type internal heat preservation device includes a motor Iand a motor II.When a curtain is unrolled, the motor I drives a rope-coilling shaft to rotate through the transmission of a motor main belt I; a traction rope is twined on the rope-coiling shaft; thetraction rope pulls a heat preservation quilt II and a heat preservation quilt III twined on an upper scroll so that the heat preservation quilt II and the heat preservation quilt III spread; the spreading of the heat preservation quilt II and the heat preservation quilt III spread drives the upper scroll to rotate; the rotation of the rope-coilling shaft and the upper scroll are driven through aside main belt, and a side scroll I and a side scroll II are respectively driven to rotate; a heat preservation quilt I and a heat preservation quilt IV twined on the side scroll I and the side scroll II are gradually spread; when the heat preservation quilt I, the heat preservation quilt II, the heat preservation quilt III and the heat preservation quilt IV are completely spread, the curtain isunrolled; when the curtain is unrolled, the motor II is started and the motor I is turned off.The device provided by the invention has the advantages of reducing influence of external factors such asthe environment, reducing the load of an active shaft of traditional internal heat preservation quilts through dividing a heat preservation quilt into four parts, improving retracting and releasing efficiency, being good in transmitting capability of a power device and realizing synchronous transmission.

Description

technical field [0001] The invention relates to a heat preservation device for a solar greenhouse, in particular to a segmented rolling curtain type inner heat preservation retractable device for a solar greenhouse. Background technique [0002] At present, the heat preservation of solar greenhouses is generally carried out by external soft covering materials. When sunlight is required, the covering materials are rolled or unfolded through the roller shutter device. The biggest disadvantage of the external heat preservation quilt is that it is poor in water resistance and difficult to replace. It is not easy to maintain, and at the same time, in rainy and snowy weather, the rain or snow load outside the outer covering material will hinder the retraction of the insulation quilt, increase the resistance, the insulation quilt cannot be rolled up, and the sunlight cannot shine on the inside of the greenhouse, which affects the growth of plants in the greenhouse. At present, the ...

AI Technical Summary

Problems solved by technology

The currently developed internal thermal insulation device overcomes the defects of the traditional external thermal insulation quilt to a certain extent, but due to the limited space in the greenhouse, manual operation is not easy, so a power device with good transmission performance is urgently needed to complete the work of rolling and spreading the curtain.
