Description

A kind of anti-freeze bridge
Technical field
The utility model relates to a kind of anti-freeze bridge.
Background technology
Whenever winter is to early spring, China's most area all can occur that pavement of road freezes accumulated snow phenomenon, and easily cause traffic accident, casualties event happens occasionally, and also can cause traffic paralysis time serious, is unfavorable for the construction and development of national economy.Highway bridge is erected in rivers,lakes and seas and between valley, makes the building that traffic etc. can pass through smoothly.Because it is suspended in the air, the speed of cooling is obviously faster than highway pavement, when surface temperature is lower than 0 DEG C, as icing accumulated snow phenomenon can be there is when bridge floor having ponding or snow, especially the bridge floor of the upper and lower gradient is had, as city neutrality is built bridge, crash because icing accumulated snow causes automobile to slip by slope and happen occasionally, that passes through to vehicle safety and have a good transport and communication network is very harmful.
In view of this, Chinese patent 201320098337.1 discloses the highway bridge of the anti-freeze accumulated snow of a kind of New Pre, comprise the electric heater unit be layed in above bridge board, described electric heater unit comprises power supply and multiple heating tube be connected with power supply, and the master switch between power supply and heating tube; Described heating tube comprises heating wire, and the high-temperature insulation material being coated on heating wire periphery is coated on the metal tube outside insulation materials; Be provided with the thermal conductive network of metal wire knitted between heating tube, each heating tube all controls the switch of this heating tube power on circuitry or power-off with one and an earth leakage protective device is connected, and described power supply provides for the solar power system be located on bridge limit.The beneficial effects of the utility model are: environment friendly and pollution-free, performance safety is reliable, simple operation.But mainly there is following problem in it: 1. need to consume a large amount of electric energy, cost is high; 2. need manual control switch, use inconvenience.
Utility model content
Problem to be solved in the utility model is to provide a kind of energy-conservation, cost is low, automaticity is high anti-freeze bridge.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of anti-freeze bridge, comprise bridge body, it is characterized in that: in described bridge body, be equipped with many heat pipes, two terminations of described heat pipe respectively with the first water pipe, second water pipe connects, described first water pipe, second water pipe is connected with the heat interchanger be arranged in geothermal well respectively, described first water pipe is provided with water pump, described bridge body is provided with temperature pick up and control box, relay and pcb board is provided with in described control box, described pcb board is assigned A/D module and single-chip microcomputer, described A/D module respectively with described temperature pick up, single-chip microcomputer connects, described relay respectively with described single-chip microcomputer, water pump is electrically connected, described heat interchanger is built with conductive fluid.
Preferably, above-mentioned anti-freeze bridge, wherein said A/D module adopts HX711AD chip, and described single-chip microcomputer adopts STC89C52RC chip.
Preferably, above-mentioned anti-freeze bridge, wherein said heat interchanger comprises two sinuous coils linked together.
Preferably, above-mentioned anti-freeze bridge, the surface of wherein said first water pipe and the second water pipe is provided with insulation layer, and described insulation layer is prepared from by polyurethane.
Preferably, above-mentioned anti-freeze bridge, wherein said control box is connected with lid.
Technique effect of the present utility model is mainly reflected in: temperature pick up can detect temperature and by signal transmission A/D module, A/D module converts the signal into data signal and passes to single-chip microcomputer, when the temperature detected is lower than zero degrees celsius, Single-chip Controlling cut-off, power supply starts to power to water pump, conductive fluid starts to circulate between heat interchanger and heat pipe, and automaticity is high; By the circulation of conductive fluid, by the heat extraction of underground out, and be transmitted on bridge body, prevent on bridge body and freeze, cost is low, and energy-saving effect is obvious; Heat interchanger comprises two sinuous coils linked together, and design improves heat exchanger effectiveness like this.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the longitudinal sectional view of the bridge body in the utility model;
Fig. 3 is the structural representation of the first water pipe in the utility model;
Fig. 4 is the structural representation of control box of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, do to tell about into a ground to detailed description of the invention of the present utility model, be easier to make the technical solution of the utility model understand and grasp.
As shown in Figure 1,2,3, 4, a kind of anti-freeze bridge, comprise bridge body 1, many heat pipes 2 are equipped with in bridge body 1, two terminations of heat pipe 2 are connected with the first water pipe 3, second water pipe 4 respectively, first water pipe 3, second water pipe 4 is connected with the heat interchanger 6 be arranged in geothermal well 5 respectively, and heat interchanger 6 is arranged in the water of geothermal well 5, and heat interchanger 6 comprises two sinuous coils linked together.First water pipe 3 is provided with water pump 7, bridge body 1 is provided with temperature pick up 8 and control box 9, relay 91 and pcb board 92 is provided with in control box 9, pcb board 92 is assigned A/D module 93 and single-chip microcomputer 94, A/D module 93 is connected with temperature pick up 8, single-chip microcomputer 94 respectively, relay 91 is electrically connected with single-chip microcomputer 94, water pump 7 respectively, and heat interchanger 6 is built with conductive fluid, and conductive fluid is water.
