Abstract

The invention relates to intelligent visibility detection equipment for traffic safety monitoring of tunnels. The intelligent visibility detection equipment comprises a telescopic mechanism, an emitter, a receiver and two movable mechanisms, wherein each movable mechanism comprises a movable platform, a lifting mechanism, a lifting platform and a drying mechanism, the lifting mechanism comprises afixed block, a movable block, a driving unit and a telescopic frame, and the drying mechanism comprises a direction adjusting mechanism, a spraying head, an air guide pipe and a drying box. Accordingto the intelligent visibility detection equipment for the traffic safety monitoring of the tunnels, the distance between the two movable platforms is changed by virtue of the telescopic mechanism, the height positions of the lifting platforms are changed by virtue of the lifting mechanisms, and the emitter and the receiver can be subjected to visibility detection at different positions, so that the detection range of the equipment is substantially increased; and furthermore, hot air is conveyed by virtue of the drying boxes, the angles of the spray heads are adjusted by virtue of the direction adjusting mechanisms, and water mist on mirror surfaces of the emitter and the receiver is evaporated, so that the visibility in the tunnels can be accurately detected by virtue of the equipment incloudy and rainy weather.

Description

technical field

[0001] The invention relates to the field of tunnel monitoring equipment, in particular to an intelligent visibility detection equipment used for tunnel traffic safety monitoring. Background technique

[0002] Visibility, also known as visibility, refers to the maximum distance at which an observer can clearly see an object under normal vision, and is usually equivalent to the "sight distance". Visibility is widely used in surface road tunnels. If the visibility is too low, the driver will easily make mistakes in judging the obstacles and pedestrians ahead, which will affect the intuitive feeling of orientation, positioning, confirmation of distance and speed feeling during driving in the tunnel. In road tunnels, visibility is the main factor that must be considered in normal operation and in fire accidents. At present, people usually use CO / VI detectors to detect the visibility inside the tunnel.

[0003] However, because the existing visibility detection...

Embodiment Construction

[0027] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0028] Such as Figure 1-Figure 4 As shown, an intelligent visibility detection device for tunnel traffic safety monitoring includes a telescopic mechanism, a transmitter 1, a receiver 2, two slide rails 3 and two moving mechanisms, the vertical section of the slide rail 3 The shape of the U-shaped section is U-shaped, and the opening of the U-shaped section is upward. The telescopic mechanism is located between two slide rails 3, and the two moving mechanisms are respectively arranged on both sides of the telescopic mechanism. Among the two moving mechanisms, one of them moves The mechanism corresponds to the transmitter 1, and the other moving mechanism cor...
