Description

Technical Field

[0001] The utility model belongs to the technical field of road supporting engineering, and in particular relates to a device for identifying and processing icing on a bridge pavement. Background Art

[0002] Meteorological disasters are a major cause of traffic accidents, especially in winter, when freezing roads can easily lead to major accidents. Unlike solid foundations on ground roads, bridges are mostly suspended overhead structures. Without the ground's heat, the heat quickly dissipates once temperatures drop, causing ice to form. Therefore, in cold or snowy weather, ordinary roads, due to their higher surface temperatures, remain frozen, while bridge pavement, at its lower surface temperature, freezes, posing a serious threat to traffic safety.

[0003] At present, when dealing with the problem of bridge icing, the identification, prevention and treatment of bridge icing is generally carried out through manual inspections, spraying deicing agents with engineering vehicles or mechanical deicing. However, there are the following shortcomings: (1) Due to the busy traffic on the bridge section, manual inspections in low temperature and severe weather conditions themselves have certain safety risks; in addition, manual inspections are also inefficient and cannot predict the time when the bridge will freeze, which will delay the opportunity to prevent bridge icing; at the same time, when dealing with sudden severe weather, manual inspections are difficult to achieve real-time monitoring and timely treatment. (2) Using engineering vehicles to spray deicing agents or mechanical deicing is not only inefficient, but also causes traffic obstruction on busy bridge sections. In addition, it is also impossible to deal with sudden ice and snow or sudden drops in temperature in a timely manner. Utility Model Content

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] A bridge road surface icing identification and treatment device, please refer to Figures 1 to 5 , which includes: a temperature and humidity sensor 1 pre-buried in the bridge deck, an ice-melting agent storage tank 2 arranged near the bridge, an ice-melting agent delivery pipe 3 arranged on the dividing strip 14 along the bridge direction and connected to the ice-melting agent storage tank 2, atomizing nozzles 4 evenly arranged on both sides of the dividing strip 14 along the bridge direction for spraying ice-melting agent on the bridge deck on both sides of the dividing strip 14, a delivery pump 5 for pumping the ice-melting agent in the ice-melting agent storage tank 2 to the ice-melting nozzle 4 through the ice-melting agent delivery pipe 3, a working bracket 6 evenly arranged on the dividing strip 14 along the bridge direction at certain intervals, a bridge deck camera 7 arranged at the end of the working bracket 6 for photographing and obtaining bridge deck image information, an infrared ice sensor 8 arranged at the end of the working bracket 6 for monitoring and obtaining bridge deck ice thickness information, and an administrator terminal communicatively connected to the temperature and humidity sensor 1, the bridge deck camera 7 and the ice sensor 8; the administrator terminal is not shown in the figure; in the above structure, the temperature and humidity sensor 1 can be There are multiple bridge cameras 7, which are evenly distributed on the bridge deck along the bridge direction. The temperature and humidity sensors can collect temperature and humidity data of the bridge in real time and transmit them to the administrator terminal. The bridge deck camera 7 is a 3-5 million pixel high-definition camera used for road monitoring. The number and spacing of the bridge deck cameras 7 should be sufficient to ensure that the captured images can cover all sections of the bridge. The bridge deck image information captured by the bridge deck cameras 7 can be sent to the administrator terminal in real time. When the infrared ice sensor 8 is working, since the absorption coefficients of infrared light in ice and water are different, and the infrared reflection coefficients of ice surfaces of different thicknesses are also different, the infrared ice sensor 8 transmits and receives infrared rays to the bridge deck, analyzes the absorption coefficients of infrared light of different wavelengths to determine whether the medium it passes through is ice or water, and then irradiates the ice surface with infrared light of the same wavelength. The ice thickness information can be obtained through the infrared reflection coefficient of the ice surface.

[0025] The working principle or usage method of the present invention is as follows: the temperature and humidity sensor collects the real-time temperature and humidity data of the bridge and transmits it to the administrator terminal. The administrator can view the data through the administrator terminal. When the real-time temperature and humidity data of the bridge reaches the temperature and humidity warning value, the administrator can turn on the delivery pump 5 to pump the ice melting agent stored in the ice melting agent storage tank 2 to the atomizing nozzle 4 through the ice melting agent delivery pipe 3, and then spray the ice melting agent on the bridge surface to prevent the bridge surface from icing in advance; in actual application, the administrator can understand the future weather conditions through weather forecast information. When approaching ice and snow weather or weather with a sudden drop in temperature, the administrator should pay attention to the real-time temperature and humidity data of the bridge obtained by the administrator terminal in time, so as to check the equipment in advance, and turn on the delivery pump 5 at the appropriate time to spray the ice melting agent on the bridge surface through the atomizing nozzle 4 to prevent the bridge surface from icing in advance; in addition, the administrator can The terminal has built-in program software that compares the real-time temperature and humidity of the bridge received with the temperature and humidity warning values. If the real-time temperature and humidity data reaches the temperature and humidity warning values, an alarm message is issued to remind the management personnel, or an instruction is issued to automatically control the start of the delivery pump 5, and spray the ice melting agent on the bridge deck through the atomizing nozzle 4 to prevent the bridge deck from icing in advance; after the ice melting agent is sprayed on the bridge deck to prevent icing, the bridge deck camera 7 can capture and obtain image information of the bridge deck, and the infrared ice sensor 8 can be used to monitor the ice thickness of the bridge deck. The bridge deck image information and ice thickness information will be transmitted to the administrator terminal in real time. The management personnel can view the bridge deck image information and ice thickness information through the administrator terminal to judge the effect of preventing the bridge deck from icing, and take corresponding subsequent deicing measures in a targeted manner, such as continuing to spray the deicing agent through the atomizing nozzle, or using mechanical deicing.

Based on the above arrangement, in spring or summer when the temperature is high and the bridge deck does not freeze, the switches of the solenoid valves 12 at different positions can be reasonably controlled to directly deliver clean water in the tap water network to the water pipe 11 and the de-icing agent delivery pipe 3 in sequence, and finally to be sprayed out through the atomizing nozzle 4 to achieve daily cleaning of the bridge deck. In addition, when it is necessary to pump clean water into the de-icing agent storage tank 2 to prepare liquid de-icing agent, the clean water can also be directly delivered to the de-icing agent storage tank 2 through the water pipe 11.
