Problems solved by technology

However, adding this device to a highway tunnel that has already been built still requires cutting the road surface to embed the detection device. At the same time, the device can only realize early warning and prompting of icing, and cannot actively remove icing.
[0005] Most of the existing deicing technologies adopt the method of time intervention, that is, the road surface has been covered with ice and snow, and the relevant staff carry equipment to remove ice and snow. Hidden dangers still pose a certain threat to road traffic safety

Embodiment 1

[0025] Such as figure 1 Shown, a kind of road deicing device of expressway tunnel mouth, comprises solar power generation device, remote sensing type traffic weather automatic station 2, active deicing device and central processing unit, described remote sensing type traffic weather automatic station 2 and active deicing device Connect to the CPU.

[0026] The active deicing device includes a pillar 4 and a heating system installed on the pillar 4, the heating system includes an air inlet, a blower, a heater, and an air outlet 3, and the air outlet 3 is arranged on the side of the pillar 4 close to the road. On one side, the air inlet is arranged on the support 4 opposite to the air outlet 3, and the air blower and the heater are arranged in the hollow inside of the support, so that the remote sensing type traffic weather automatic station 2 can detect that there is water and ice on the road surface. 1. When the friction force of the road surface is reduced due to snow, the c...

Embodiment 2

[0038] Such as image 3As shown, the difference between this embodiment and Embodiment 1 is only the active deicing device. The active deicing device of this embodiment includes a pillar 4 and a deicing agent sprayer installed on the pillar 4, and the deicing agent is sprayed The sprinkler includes a nozzle 6 and a deicing agent containing chamber, the nozzle 6 is installed on the side of the pillar 4 close to the road, and the deicing agent accommodating chamber is installed in the hollow interior of the pillar 4 . When the remote sensing detection device detects that there is ice or snow on the road surface, resulting in reduced friction and affecting driving safety, the central processing unit controls the opening of the snow-melting agent sprayer, and timely removes the ice and snow on the road surface by spraying the snow-melting agent on the road surface, so as to avoid Thickening of ice and snow leads to slippery roads and traffic accidents.

Abstract

The invention discloses the technical field of road surface deicing, in particular to an expressway tunnel portal road surface deicing device, which comprises a power supply module, a remote sensing detection device, an active deicing device, an information issuing device and a central processing unit, wherein the remote sensing detection device collects tunnel portal road surface information and sends the information to the central processing unit for analysis and judgment, the opening and closing of the active deicing device are controlled, and the road surface information is displayed through the information issuing device. The expressway tunnel portal road surface deicing device has the advantages of monitoring the situation of the tunnel portal road surface in real time and eliminating the factors that affect the anti-skid performance on the tunnel portal road surface to ensure the safe passage of vehicles.

Description

technical field [0001] The invention relates to the technical field of road surface deicing, in particular to a road surface deicing device at an expressway tunnel entrance. Background technique [0002] With the rapid development of expressways, more and more tunnels are built on expressways. However, the existence of tunnels faces many potential disasters. Ice on the road surface at tunnel entrances is a disaster that often causes traffic accidents. Due to the tunnel's own structure and the flow of hot and cold air continuously driven by passing vehicles, the temperature difference between the inside and outside of the tunnel is generated, and the road surface at the tunnel entrance is very easy to freeze after rain and snowfall. In addition, when the driver enters the tunnel, the large difference in light inside and outside will produce a black hole effect, which cannot quickly respond to the environmental conditions and traffic conditions near the tunnel entrance, which ...
