An intelligent safety fence device for a substation

Abstract

The invention discloses an intelligent safety fence device for a substation, which is characterized in that it includes two support rods (7), a retractable rope (11), etc., and an infrared signal emission and image recording synthesis unit (8) includes a first lithium battery (8-8), PCB board (8-5), infrared transmitting circuit (8-7), first power supply terminal (8-9), probe (8-4), etc., PCB board (8-5) is equipped with There are crystal oscillator circuit (8-1), central integrated intelligent module (8-2), video storage unit (8-3), USB interface (8-6); infrared signal receiving and voice alarm synthesis unit (9) includes the second Lithium battery (9-9), second PCB board (9-2), infrared signal receiving tube (9-1), second power supply terminal (9-8), position adjustment stepper motor (9-6), alarm The recording player (9-7), the second lithium battery (9-9), and the second PCB board (9-2) are provided with an infrared signal decoder (9-3) and a signal demodulation control circuit (9-4 ), infrared signal receiving tube angle adaptive closed-loop adjustment mechanism (9-5), the present invention effectively prevents accidents; ensures that the device always works reliably, effectively avoids false alarms; and checks the isolation effect in real time.

Description

Technical field: [0001] The invention relates to an intelligent safety fence device for a substation, which belongs to the field of substation operation inspection of a power system. Background technique: [0002] The safety fence is a commonly used device in the work of enclosure, isolation, shielding, etc. It is mainly used in the maintenance of electrical equipment in power plants and substations, electrical experiments, power distribution maintenance, etc., and is the most commonly used in substation operation maintenance tests. One of the tools. Common fences mainly include fiberglass fences, insulated telescopic fences, safety fences, safety flag fences and the latest electronic safety fences. The hidden dangers and deficiencies of the conventional fences currently used on the job site mainly include: 1) Lack of effective warnings and reminders. In the case of a large number of workers on the job site, frequent access, and weak monitoring forces, it is impossible for ...

Problems solved by technology

The hidden dangers and deficiencies of the conventional fences currently used on the job site mainly include: 1) Lack of effective warnings and reminders. In the case of a large number of workers on the job site, frequent access, and weak monitoring forces, it is impossible for the staff to enter the live equipment area without authorization. 2) The fence is not strong enough and is easily damaged. The current general method of winding the rope around the fixed bracket is prone to loosening and tripping of the fence when it is affected by external forces, causing damage to live equipment. isolation failure

Since the latest electronic fence cannot well solve the problem of precise alignment of the transceiver device under the influence of external force, it is prone to false alarms caused by interruption of signal reception

Safety fences play an irreplaceable and important role in the field of power system substation inspection, but the existing safety fences cannot fully meet the requirements of on-site work for relevant safety measures, and there are many hidden dangers
