上拉式卷帘是最早使用的一种卷帘方式,但因实际使用中存在较大安全隐患而逐渐减少应用。为此,从安全防护角度出发,设计了一种全防护型的上拉式卷帘系统,包括研制适合温室使用的限位装置,提出并设计了应急、维修模式和自诊断装置等。经过现场测试,该系统能够有效杜绝安全事故发生,保证卷帘系统的稳定性和可靠性,具有推广和应用价值。
Pull-up roller shutter is the earliest use of a shutter method, but due to the actual use of a greater security risk and gradually reduce the application. Therefore, from the point of view of safety protection, an all-protection pull-up roller shutter system is designed, which includes the development of limit device suitable for greenhouse application, the design of emergency and maintenance mode and self-diagnosis device. After field test, the system can effectively prevent the occurrence of safety accidents and ensure the stability and reliability of the roller shutter system, which has the promotion and application value.
