Embodiment Construction

[0017] The safety fence is composed of multiple unit guardrails spliced ​​together. A pressure touch switch is installed between the two unit guardrails that are in contact with each other or a magnetic buckle is installed on the two unit guardrails respectively; it also has a fence disconnection alarm circuit: The positive pole of the 12V battery BT1 is connected in series with the resistor R6 and then connected to the negative pole of the regulator tube D1, the capacitor C2 is connected in parallel with the battery BT1, the positive pole of the electrolytic capacitor C1 is connected to the positive pole of the battery BT1, and the negative pole of the electrolytic capacitor C1 is connected to the negative pole of the battery BT1;

[0018] One end of the resistor R7 is connected to the positive pole of the battery BT1, the other end of the resistor R7 is connected to the base of the composite transistor Q1, the collector of the composite transistor Q1 is connected to the positi...

Abstract

The invention discloses a safety fence for a power maintenance site, which is formed by splicing a plurality of unit protective guards. A pressure-touch switch is arranged between two unit protective guards which are mutually contacted, or the two unit protective guards are respectively provided with a magnetic button. A fence disconnection alarming circuit mainly consists of a voltage-stabilizing circuit (adopting a voltage-stabilizing diode for stabilizing voltage), a triode switch circuit, a power amplifying circuit and an alarming circuit. When the magnetic button or the pressure-touch switch at any protective guard in the fence is switched off, the triode switch circuit is disconnected, and the alarm gives an alarming sound. The safety fence disclosed by the invention has the advantage that the illegal behavior for crossing over safety guards can be effectively prevented, and has the characteristics that the structure is simple and practical and the construction safety can be ensured.

Description

technical field [0001] The invention relates to a safety guardrail for construction, in particular to a guardrail for electric power maintenance construction and having an alarm function. Background technique [0002] The existing guardrail is one of the important means to ensure the safety of the construction site. The traditional guardrail has soft and hard fences, and is made of nylon, ABS, stainless steel, etc. No matter whether it is soft or hard fence, there is no sound or light. Alarm function. In actual work, due to the convenience of the map, the staff often violate the rules and regulations by crossing the safety fence, and sometimes unsafe accidents occur due to personal injury and death due to crossing the safety fence and entering live equipment. Therefore, the existing fence still has safety hazards during actual construction Hidden danger. Contents of the invention [0003] The purpose of the present invention is to provide a safety fence for electric powe...
