Intelligent portable safety fence

Abstract

The invention relates to an intelligent portable safety fence which comprises a plurality of stand columns connected through extensible belts. The extensible belts are wound in the stand columns, extend out when being pulled and automatically rewinds into the stand columns when not pulled. The intelligent portable safety fence is characterized in that the stand columns are provided with pyroelectric sensors and alarms, the pyroelectric sensors are provided with switches and electrically connected with the alarms, and the pyroelectric sensors are used for receiving and magnifying infrared radiation generated by movement of people and driving the alarms to send alarming signals. The intelligent portable safety fence is simple in structure, has the functions of automatically detecting mistaken intrusion of people, alarming in advance, striking warning marks and the like, can protect absolute security of people and equipment in high-voltage testing sites and can improve safety of the high-voltage testing sites.

Description

technical field [0001] The invention relates to a fence, in particular to an intelligent portable safety fence used in a high-voltage test site to ensure the safety of personnel and equipment. Background technique [0002] On-site electrical tests are mostly high-voltage tests, and the test voltage is often greater than 10kV, of which the main transformer withstand voltage test voltage is above 80kV (110kV main transformer). The electrical test needs to ensure the absolute safety of personnel and equipment, which puts forward extremely high requirements for the safety measures of the test. The safety fence has played a great role in ensuring the safety of personnel and equipment. At present, the fence used in the high-voltage test site is already portable, and also has some functions such as effectively preventing people from accidentally intruding into the test area, but generally does not have automatic detection. Functions such as intrusion of personnel by mistake, early...

The safety fence has played a great role in ensuring the safety of personnel and equipment. At present, the fence used in the high-voltage test site is already portable, and also has some functions such as effectively preventing people from accidentally intruding into the test area, but generally does not have automatic detection. Functions such as false intrusion of test personnel, early warning, and eye-catching warning signs

Functions such as automatic detection of intrusion by on-site security fences, early warning, and eye-catching warning signs have very important practical significance. Generally, one person monitors, and the rest of the personnel operate the instrument and record data, and most of the test site personnel are complicated, and the safety awareness of various personnel is different, and the danger of the high-voltage test is unclear. Monitoring blind spots greatly reduces the safety of personnel and equipment
