Anti-drowning benchmarking system

Abstract

The invention discloses a drowning-proof mark post system, and belongs to the field of safety facility appliances, which can play a strong caution role. The drowning-proof mark post system includes acentral mark pole, lateral mark poles, and flexible shafts; the central mark pole and the lateral mark poles are tubular, sliding ways are arranged on tubular walls of the central mark pole and the lateral mark poles, floaters and sliding signs are arranged outside the tubular walls; the sliding signs pass through the sliding ways arranged on the tubular walls via sliding bars on circular inner walls thereof and stretch into tubular cavities of the central mark pole and the lateral mark poles; upper baffle plates, lower baffle plates, core rods, and bevel gear groups are arranged on inner walls of the tubular cavities of the central mark pole and the lateral mark poles; hollow ends of the sliding bars are jointed to grooves of the core rods; an outer end of one flexible shaft is connectedto the core rod in the center of the corresponding lateral mark pole, and an inner end of the flexible shaft is connected to a corresponding bevel gear. The drowning-proof mark post system is suitablefor drowning-proof caution regions in rivers and lakes.

Description

technical field [0001] The present invention relates to personal safety facilities, and specifically refers to an anti-drowning benchmarking system arranged on a river bank. Background technique [0002] Water conservancy management departments often set up water level elevation devices such as benchmarks on rivers and lakes to facilitate people to observe and understand water level changes, or to remind people to pay attention to safety and prevent drowning hazards. For example, for a river, the deeper place is the main channel of the river, that is, the middle line between the two banks of the river. This place is the deepest part of a certain section of the river, and such places are often far away from the shore. Here, the benchmark that can accurately mark the water level and depth will be difficult to see the marked value because the distance is too far. Consequences create a psychological impact that deters people from taking dangerous actions in the water. Content...
