Description
Technical field
The utility model relates to the deicing device of railway tunnel, is specially a kind for the treatment of technology for tunnel seepage closed drain Intelligent electric heating deicing device.
Background technology
Existing Railway Line Tunnel Water Leakage is a ubiquitous tunnel defect,, wherein in operation, there is water burst in various degree, leak, emit water, drip, seep water, 1/3 left and right that accounts for total the number in system-wide tunnel of the phenomenon such as wet water in approximately 50000 of the existing railway tunnel of China.Percolating water can cause the destruction of tunnel lining structure, affects the stable and safety in tunnel, can cause again the tunnel basic harm influence driving of rising soil simultaneously.In winter tunnel, during mercury dropped to 0 ℃ left and right, icing phenomenon mostly occurs in the location that leaks.Have freeze after sealed the eye that leaks, freeze and continue development, fouling of clearance gauge impact driving.Serious meeting causes contact net to connect electricity, and ice overflows rail, and sidewall is invaded limit, to traffic safety, brings great harm.Tunnel Water Leakage, the regulation of freezing are also a general character difficult problem in the world, and technician has carried out a large amount of research and innovations both at home and abroad.My section mostly is over the years to adopt sets up lining cutting draining undercut processing abutment wall and arch ring percolating water, after processing percolating water, be faced with a new problem, after the Seepage water of winter severe cold area, lining cutting draining multigelation causes closed drain frost fracture, draining undercut frost heave shortcake splits the situation that peeling comes off, make it not bring into play due effect, and greatly increased workload and the work difficulty of tunnel maintenance.The more important thing is, also can destroy durability and the safety of tunnel structure, seriously jeopardize traffic safety.Current domestic trial adopts underground heat deicing device many, but implantation depth more shallow (3,4 meters of left and right under rail) in construction destroys tunnel invert simultaneously, likely causes that underground water pours in railway roadbed, causes new Disease in Tunnel Base.
Summary of the invention
The utility model, in order to solve the problem of the draining undercut ice-melt in winter of railway tunnel, provides a kind for the treatment of technology for tunnel seepage closed drain Intelligent electric-heating deicing device.
The utility model is to adopt following technical scheme to realize:
A kind for the treatment of technology for tunnel seepage closed drain Intelligent electric-heating deicing device, comprise a central intelligent temperature controller, the input of described central intelligent temperature controller is connected with temperature pick up, and the output of central intelligent temperature controller is connected with several temperature selflimiting electric tracing bands.
Central authorities' intelligent temperature control equipment can be bought in market, it is main ingredient, showing on the basis of control instrument, adopting eight micro computers is acp chip, four demonstrations, and adopt Anti-Jamming Technique, have that precision is high, reliability is strong, shock resistance is strong, easy for installation, clear reading, no parallax, can distant surveillance etc. feature, and there is the set-up function of upper lower limit value, can realize the automatic control of temperature.
Temperature selflimiting electric tracing band can be bought in market, is heater block, conducting polymer and two parallel metal wire and insulating layer, consists of.Be characterized in that conducting polymer has very high resistance positive temperature coefficient characteristic, and parallel with one another; Can be with the automatic regulation output power of the variations in temperature that is heated system.After ribbon heater switches on power, electric current forms loop through conductive material to another core by single line core.Electric energy heats up conductive material, and its resistance increases immediately, and after core band temperature rises to certain value, resistance is large, and to the degree of almost blocking electric current, its temperature no longer raises, and meanwhile conduct heat to the lower system that is heated of temperature in ribbon heater.
Temperature pick up can be experienced temperature and convert the sensor of usable output signal to.When forming a loop by two kinds of different conductors and semiconductor A and B, when its two ends interconnect, as long as the temperature at two node places is different, one end temperature is T, be called working end or hot junction, other end temperature is TO, is called free end (also claiming reference edge) or cold junction, in loop, just have electric current to produce, the electromotive force existing in loop is called thermo-electromotive force.Two kinds of different conductors or semi-conductive combination are called thermocouple.The thermoelectrical potential EAB (T, T0) of thermocouple is synthetic by contact potential and thermoelectric force.Contact potential refers to the electromotive force that two kinds of different conductors or semiconductor produce in contact position, this electromotive force and two kinds of conductors or semi-conductive character and relevant in the temperature of contact point.
During work, the draining undercut that temperature selflimiting electric tracing band is wrapped in to railway tunnel is outside.As shown in Figure 2, the signal of telecommunication of being sent here by temperature pick up carries out after cold junction auto-compensation in measuring bridge road, sending into amplifier amplifies signal, signal after amplification converts frequency to and sends into single-chip microcomputer through A/D, through signal digital, processes, and a railway digital shows, another road receives regulating networks signal, the control signal of needs and duty indication are exported in the comparison operation of stipulating simultaneously, and then the heating of controlling electric-heating belt whether.
In order to guarantee the smooth and easy operation of tunnel electro-heat deicing apparatus, during installation, should require to select suitable setting height(from bottom) position in conjunction with actual conditions according to the gauge in tunnel, and main device is carried out to waterproofing protection processing.After entering winter, open to guarantee that Tunnel Water Leakage draining undercut do not freeze, administrative staff should have the duty of periodic checkout gear, and close this device after finishing in the winter time, and dedusting and electric circuit inspection are carried out in inside, prevent from that electric equipment is aging to occur short circuit.
