Description

Technical Field

[0001] The utility model belongs to the technical field of municipal road current limiting, and in particular relates to a municipal road current limiting device. Background Art

[0002] Municipal road flow limiters are short-term measures designed to prevent excessive traffic pressure on lines or road networks. They primarily operate by activating valves or other control devices to restrict or prevent additional vehicles from entering. In this way, flow limiters effectively control road traffic flow. Their primary purpose is to manage passenger flow distribution, reduce transportation pressure and accident risks, thereby improving road efficiency and ensuring traffic safety. They are widely used on various municipal roads, particularly in sections with heavy traffic and a high incidence of accidents.

[0003] Chinese Patent Publication No. CN218204048U discloses a municipal road current limiting device, comprising a base plate and a guardrail motor box, a support column mounted above the base plate, a warning light mounted in the middle of the support column, a display screen mounted above the warning light, a solar panel assembly mounted above the display screen, a camera mounted on the right side of the solar panel assembly, a guardrail motor box mounted on the right side of the support column, a bracket mounted inside the guardrail motor box, a motor mounted in the middle of the bracket, a motor connected to a motor drive wheel on the outside of the motor, a drive belt connected to the outside of the motor drive wheel, a rotating shaft mounted above the motor drive wheel, a second protrusion mounted above the rotating shaft, a limit block mounted above the second protrusion, and an electric guardrail mounted on the outside of the rotating shaft. This utility model is equipped with a camera, and when the camera detects a large number of passing vehicles, the motor starts to drive the rotating shaft to lower the electric guardrail to limit the flow of vehicles.

[0004] In actual use of this utility model, the existing municipal road flow limiting device usually uses a guardrail to intercept vehicles, thereby playing a role in flow limiting. However, the length of the guardrail of this utility model is usually fixed, which means that it can only limit the flow of municipal roads with a fixed width. Due to the differences in the widths of different municipal roads, the fixed-length guardrail may not be able to meet the flow limiting requirements of all municipal roads. When it is necessary to limit the flow of municipal roads of other widths, its adaptability is insufficient, and the length of the guardrail needs to be replaced or adjusted, and it may even be necessary to use flow limiting devices of other sizes and specifications, which will make the applicability of the municipal road flow limiting device lacking.
