Safety alarm fence

Abstract

The invention belongs to the field of power equipment testing or power equipment maintenance auxiliary application equipment and relates to a safety alarm fence which comprises pillars and warning tapes arranged between the pillars. The bottom ends of the pillars are provided with bases. Two ends of the warning tapes are fixed to sliding chutes of pillar outer walls through sliding rods, and two sides of each pillar are provided with sliding chutes. The front panels of the pillars are provided with switches 1, infrared probes and alarms, the switches 1, the infrared probes and the alarms are connected to control units which are connected to power supply devices. Each of the power supply devices comprises a storage battery and a solar panel, the storage battery is arranged in a pillar, thesolar panel is arranged at the top end of the pillar and is connected to a photovoltaic controller through a wire, and the photovoltaic controller is connected to the storage battery through a wire. The safety alarm fence is reasonable in structure design, boundary-crossing personnel can be timely detected and alarm is emitted timely to prompt the staff, and the solar power is used, which is environment-friendly and convenient.

Description

technical field [0001] The invention relates to a safety alarm fence, which belongs to the field of electric equipment test or auxiliary application equipment for electric equipment maintenance. Background technique [0002] At present, there are two types of safety fences commonly used in power systems. One is composed of simple safety warning tapes. It is used to simply surround the equipment test area or maintenance site. It is easy to carry, but because it is relatively light and soft, It is easy to be damaged and lost; the other is relatively complicated, consisting of a safety warning belt, a supporting main steel pipe and a base. Heavy and inconvenient to carry and transport. These two commonly used safety fences are only used to prevent people from crossing over and have a simple warning function. In many cases, the fences are useless, and illegal operations across the warning line occur from time to time. Especially during on-site testing of high-voltage equipment...

[0002] At present, there are two types of safety fences commonly used in power systems. One is composed of simple safety warning tapes. It is used to simply surround the equipment test area or maintenance site. It is easy to carry, but because it is relatively light and soft, It is easy to be damaged and lost; the other is relatively complicated, consisting of a safety warning belt, a supporting main steel pipe and a base. Bulky, inconvenient to carry and carry

These two commonly used safety fences are only used to prevent people from crossing and have a simple warning function. In many cases, the fence is useless, and illegal operations across the warning line occur from time to time.

Especially in the on-site test of high-voltage equipment or the maintenance of high-voltage equipment, because the on-site personnel are not optimistic about the "tiger's mouth", other workers enter the site, and accidentally touch live equipment, which may easily cause electric shock accidents
