Intrinsically safe anti-explosion tension electronic fence

Abstract

The invention provides an intrinsically safe anti-explosion tension electronic fence which is characterized in that a control rod is vertically installed on a base through a fixing piece, a force bearing rod is vertically installed on the base through a support, a plurality of transversely-arranged alloy wires are arranged between the control rod and the force bearing rod, one end of each alloy wire is connected with the force bearing rod and the other end of each alloy wire is connected with the control rod through a tension spring, wire clamps are arranged on the alloy wires, a middle column is arranged between the control rod and the force bearing rod and installed on the base, the alloy wires penetrate through the middle column, and a warning board is hung on the alloy wire located at the uppermost end. And a tension detector and a safety barrier circuit are arranged in the control rod. According to the invention, the safety barrier circuit is built in the product, so that additional signal isolation is avoided when the product is used, the cost input during installation is reduced, and the safety and stability of the product when the product is used in a special environment are improved.

Description

technical field [0001] The invention relates to the technical field of electronic fences, in particular to an intrinsically safe explosion-proof tension electronic fence. Background technique [0002] In order to use the existing tension electronic fence in an environment with explosion-proof requirements such as flammable and explosive, it is necessary to add an external safety barrier module outside the equipment body, and add an explosion-proof junction box in the safe area to connect the safety barrier to the equipment. The construction and installation are very complicated. cumbersome. [0003] At the same time, the safety barriers on the market basically only provide one of the two functions of signal and signal isolation, and the power supply of equipment needs to add a safety power supply. Moreover, when detecting the tension of the alloy rope of the tension electronic fence, the alarm detector produces false alarm results due to poor environmental adaptation. Con...
