Description
Technical field
This utility model relates to regulating and controlling frozen soil engineering temperature field technical field, more particularly, to a kind of for cooling down the cold wind harvester that highway large scale is frozen earth roadbed.
Background technology
Along with developing rapidly of Structure Dynamics In The Qinghai-tibet Region economic society, build Qinghai-Tibet highway and have become as a kind of reality necessity, and included National Highway development plan in.For passing through the highway of In Permafrost Regions of Qinghai-xizang Plateau, owing to width of subgrade is more than 20 meters, and using the black asphalt pavement that heat absorptivity is strong, its frozen soil caloric receptivity that underlies is bigger, and Frozen soil problems and subgrade stability sex chromosome mosaicism are the severeest.For permafrost region highway wide cut roadbed, indiscriminately imitate and be applied to the ventilation shaft of existing railway bed and common road roadbed and will be unable to reach cooling effect, mainly there is a reason in terms of following three: one, hotter air also can be imported roadbed at warm season while cold season imports colder air-flow by ventilation shaft, cause roadbed heat absorption to increase, bottom frozen soil is had a negative impact；Its two, the ventilation of ventilation shaft is greatly limited by meteorological condition and road-trend etc., and such as, when temperature is relatively low, wind speed is less, or wind direction is perpendicular to pipeline wind direction, all will weaken draught capacity and the cooling capacity of ventilation shaft；Its three, after ventilation shaft length is multiplied, natural wind may cannot blow through ventilation shaft because insufficient pressure and pipeline on-way resistance are relatively big, it is impossible to forms forced convection, thus limits its cooling capacity.For this practical problem, at ventilation duct air inlet automatic cold wind harvester can be installed, relatively low at outside air temperature or time ventilation shaft internal-external temperature difference reaches a certain specified conditions, start blower fan, cooler air is imported ventilation shaft；And when outside air temperature is higher, stopping blower fan, in ventilation shaft, airless passes through, and at utmost reduces roadbed heat absorption.Therefore, at utmost strengthening the ventilation shaft aeration-cooling ability more than 20 meters in large scale roadbed, it is necessary to a kind of cold wind harvester that can automatically control according to outside air temperature change and pipe internal-external temperature difference.
Although prior art discloses a kind of cold wind harvester, after being multiplied when ventilation shaft length, difference is there may be between the temperature of the ventilation shaft of zones of different, therefore there is the defect that prohibited data detection is true, thus automatically on/off cold wind harvester can not be carried out according to outside air temperature change and pass internal-external temperature difference exactly.
Utility model content
For the problems referred to above of the prior art, the utility model proposes a kind of can accurately measure pipe internal-external temperature difference for cooling down the cold wind harvester that highway large scale is frozen earth roadbed.
This utility model provides a kind of for cooling down the cold wind harvester that highway large scale is frozen earth roadbed, and wherein, described cold wind harvester includes:
Mainboard, described mainboard is made up of single-chip microcomputer and data conversion module；
Being evenly provided on the temperature detector multiple pipes outside ventilation duct Wai, the outer temperature detector of the plurality of pipe and the first data averaging module connect；
Temperature detector in the multiple pipes being evenly provided in ventilation duct, in the plurality of pipe, temperature detector and the second data averaging module connect；
Wherein, described first data averaging module is connected with the described second the most described data conversion module of data averaging module；
Described single-chip microcomputer accesses inverter, and described inverter connects direct-flow input end mouth and blower fan, and described blower fan is arranged at the ventilation mouth of pipe.
Further, the neighbouring spacing between two outer temperature detectors of pipe is 3-10 rice.
Further, in two neighbouring pipes, the spacing between temperature detector is 3-10 rice.
Compared with prior art, of the present utility model by being respectively provided with multiple temperature detector inside and outside ventilation duct, and calculate the temperature averages inside and outside pipe by the first and second data averaging module respectively, thus the temperature difference inside and outside accurately measure pipe, the most automatically this cold wind harvester of on/off.
