AI Technical Summary

Technical Problem

Existing rotating roofs are prone to jamming during the process of chasing sunlight, and the stacking of soft films can affect the entry of sunlight, resulting in heat loss and light loss.

Method used

The roof employs multiple parallel double-layer frame rotating roofs, combined with a pull-out compensation mechanism and a guiding mechanism, to ensure that the roof can completely block light and maintain vertical light entry when adjusting the tilt angle. The tilt angle is adjusted using hydraulic or electric actuators, and smooth movement is achieved in conjunction with telescopic rods and support rod assemblies.

Benefits of technology

It achieves full light intake during the light-tracking process, prevents heat loss, avoids jamming and light loss, and has a simple structure, low cost and long service life.

Abstract

The application relates to a multi-span greenhouse rotating roof with a light following function, and relates to the technical field of multi-span greenhouses. The application is used for solving the problems of easy jamming failure of the existing rotating roof and the problem of the stacking of soft films affecting the light entering. The application comprises a plurality of parallel double-skeleton rotating roofs, the front slope surface and the rear slope surface of the double-skeleton rotating roof are vertically arranged, an insertion and extraction compensation mechanism is arranged between the two adjacent double-skeleton rotating roofs, the front end of the insertion and extraction compensation mechanism is inserted into the rear slope surface of the front double-skeleton rotating roof, and the rear end of the insertion and extraction compensation mechanism is inserted into the front slope surface of the rear double-skeleton rotating roof. The application is used for the multi-span greenhouse.
