[0003] The behavior of crossing the warning zone without permission is a personal safety risk. Due to the randomness and uncertainty of the behavior of people crossing the warning zone, each illegal crossing behavior may not be immediately discovered and warned, resulting in omissions in safety production
Due to the large power production operation area and visual barriers between areas, the on-site safety management personnel cannot fully control the illegal crossing of the warning zone, nor can they follow up and stop the illegal crossing behavior in time
Due to the repeated use of safety fences in the power system, the space angle between the location of use and the fence is constantly changing, and the construction site changes in a wide range, which limits the development of electronic and information technology for safety fences.

The invention relates to a compound safety enclosing rod device with a position alarm function. The compound safety enclosing rod device comprises warning tapes; the warning tapes enclose a closed plane figure; one enclosing rod is arranged between the A end of one warning tape and the B end of an adjacent warning tape; the enclosing rod comprises a base and an upright column; the upright column is sleeved with a tape storage box, a lower rotation body and an upper rotation body; the lower part of the upper rotation body is provided with an infrared ray through-beam receiving module; and the upper part of the lower rotation body is provided with an infrared ray through-beam transmitting module. The compound safety enclosing rod device of the invention has the advantages of compact structure, advanced design, safety, reliability, easiness in implementation and low cost. The compound safety enclosing rod device is convenient to adjust emission directions so as to better receive signals. With the compound safety enclosing rod device adopted, the problems of repeated use, constant position change and difficult matching of safety enclosing rods in a power system can be solved.
Description
technical field [0001] The invention relates to a composite safety fence device with a position alarm function, which belongs to the field of electric power application. Background technique [0002] The safety fence currently used is composed of a base, a column, and a cassette warning belt, and is mainly used for electrical equipment maintenance, electrical testing, and power distribution maintenance in power plants, substations, and power distribution construction operations. The power maintenance site is usually used in conjunction with multiple safety fences, and the safety fences are connected together through the warning belt to form an effective isolation area. The safety fence is used to isolate high-voltage live parts, separate operating areas, standardize the scope of activities of operators, isolate irrelevant social personnel and vehicles from entering, control potential high-voltage electric shock risks, and ensure the safety of operators and social personnel. ...
