Safety protection and antitheft limiting emergency stop device of roller blind of greenhouse

Abstract

The invention belongs to an automatic control system, and particularly relates to a safety protection and antitheft limiting emergency stop device of a roller blind of a greenhouse. The safety protection and antitheft limiting emergency stop device of the roller blind of the greenhouse comprises a greenhouse wall (9), a greenhouse surface (10), a reel roller blind (8), a roller blind rope (7), roller blind shafts (11) and greenhouse upright shafts (2), wherein a frame-shaped antitheft device shell (6) is fixedly arranged at the edge of the top of the greenhouse surface (10); a bolt (6-1) is arranged on a right border of the antitheft device shell (6); a microswitch (6-2) is arranged on a border of the bottom of the bolt (6-1); an antitheft device shell door (4) is movably arranged on the front surface of the antitheft device shell (6); a limiting device (5) is arranged in the antitheft device shell (6); and a protection device (3) is arranged on the roller blind shaft (11) on the right side of each greenhouse upright column (2). By the safety protection and antitheft limiting emergency stop device of the roller blind of the greenhouse, safety of an operator can be guaranteed well; by the limiting module, the safety protection and antitheft limiting emergency stop device is easy and convenient to operate; and the whole device is simple in structure, easy to mount and convenient to operate, and is safe and reliable.

Description

technical field [0001] The invention belongs to an automatic control system, and in particular relates to an emergency stop device for safety protection, anti-theft, limit and emergency stop of roller blinds in greenhouses. Background technique [0002] There are many greenhouses in our country, and more than 90% of the roller shutter systems are rear-mounted pull-up systems. Because of their low cost and easy installation, they are widely used in my country, and their disadvantages are increasingly revealed. Its biggest disadvantage is its poor safety. Since the rear pull-up roller blind machine adopts a roller-rolled rope-type roller blind, the roller and rope are exposed outside, and the operator is often involved in the rope and roller, causing casualties. A devastating blow to rural households; secondly, if the operator is slightly negligent when setting the curtain, it may cause the roller blind machine to run overtravel and disrupt the rotation of the rope on the drum...
