Description
Technical field
The utility model relates to the highway safety running technology field of safeguarding.What be particularly related to is the technology of removing road surface accumulated snow.
Background technology
Road surface accumulated snow serious threat traffic safety.Particularly at bridge, these key positions of tunnel exit, road surface accumulated snow can cause serious consequence.
Traditional snow melt mode is to adopt inorganic salts Snow Agent or organic slat solution to be sprinkling upon on the accumulated snow mode that makes it to generate salting liquid with accumulated snow reaction, the freezing point that reduces accumulated snow to melt accumulated snow; The equipment that perhaps adopts warm water to spray carries out snow melt to be handled.There are a lot of problems in these traditional snow melt modes, and the salting liquid that the inorganic salts Snow Agent generates has corrosiveness to reinforcing bar, surrounding building, the network of underground circuit of bridge, and destroy the salt balance in the soil, cause certain pollution; The snow melt of organic salt Snow Agent is effective, but cost is very high, is applied to the urgent snow removing of airfield runway usually; Warm water spray appliance later stage curing requirements height is easily crossed in temperature and is formed secondary when low and freeze, and influences road.All traditional snow melt modes all are a kind of passive modes, need a large amount of manpower and materials to carry out construction operation, and cost is very high.
The utility model content
The purpose of this utility model is in order to overcome traditional road snow melt mode above shortcomings, and the underground heat that utilizes that a kind of environmentally safe is provided, can monitors the accumulated snow situation at any time and in time eliminates accumulated snow comes the device of melting road surface accumulated snow.
The geothermal pavement snow melting device of realizing the utility model purpose by U-shaped heat removing tube group, road surface heating tube, be connected the circulating water pump between U-shaped heat removing tube group and the road surface heating tube, the controller that is connected with circulating water pump is formed with the pavement behavior probe that is connected with controller.During use the road surface heat-generating pipe is embedded under the supercrust, U-shaped heat removing tube group is embedded in underground, utilizes underground heat heating heat removing tube group; The pavement behavior probe with the control road surface whether the situation of ponding or accumulated snow react to controller.When there are ponding or accumulated snow in the road surface, controller starts circulating water pump work, recirculated water in the pipeline obtains heat when being embedded in the underground U-shaped heat removing tube group that has been heated and becomes hot water, this flow of hot water route face heating tube, thereby the ponding that heat delivery is prevented the road surface to the road surface freezes, or makes the snow melting on road surface become aqueous water to flow away.When surface gathered water or the elimination of accumulated snow phenomenon, controller is the circulating water pump outage, and circulating water pump quits work.Controller can be arranged on monitoring scene, road surface together with other parts, also can be designed as remote controllers.
Consider that U-shaped heat removing tube group is embedded in the difficulty of the underground degree of depth and this situation whether underground heat can satisfy instructions for use, the one heat exchange unit that is controlled by controller can be set in the circulation line between described U-shaped heat removing tube group and the road surface heating tube, in advancing of heat exchange unit, be provided with the electromagnetic valve that is controlled by controller between the outlet pipeline, and advancing at the heat exchange unit, the water temperature probe that is connected in controller is set on the outlet pipeline. the heat exchange unit can adopt the heating equipment of compressor one class of similar air-conditioning. during operation, by water temperature probe the temperature conditions of the recirculated water in the pipeline is sent to controller, if temperature is not enough, controller then starts the work of heat exchange unit, close simultaneously and be connected in advancing of heat exchange unit, the electromagnetic valve of outlet pipeline, the recirculated water that comes from the underground heat removing tube group then is transported in the heat exchange pump assembly, if make snow melting become aqueous water to flow away to the road surface heat delivery by being transported to the road surface heating tube after the heating of heat exchange pump assembly. the temperature of recirculated water is enough, controller then cuts out the heat exchange unit, open simultaneously and be connected in advancing of heat exchange unit, the electromagnetic valve of outlet pipeline, coming from recirculated water in the underground heat removing tube group then directly is transported in the heating tube of road surface through electromagnetic valve without the heat exchange unit and finishes snow melt. and the benefit of doing like this is to make full use of underground heat, saves energy. for the full liquid that guarantees recirculated water effectively circulates, on the inlet pipeline of described circulation line and outlet pipeline, a circulating water pump can be set all and the side connects a constant pressure tank, advancing of road surface heating tube, delivery port joins with a water knockout drum and circulation line respectively, the advancing of U-shaped heat removing tube group, delivery port joins with a water collector and circulation line respectively.
When cold district uses this device, frozen for preventing recirculated water, can in recirculated water, add anti-icing fluid.
Compare with aforementioned prior art, the beneficial effects of the utility model are: become passive snow melt and be active monitoring, can prevent timely and effectively that the water route face from freezing and the formation of accumulated snow.Heat-obtaining on the spot, consume fuel is not energy-efficient; Do not have any pollution, the feature of environmental protection is good; Controllability is strong, and stable and reliable operation is safe; Initial investment is less, and operating cost is low, and the life-span is long, need not manually guard good economy performance.Be particularly suitable for the bridge of outlying mountain area, the road surface use of these key positions of tunnel exit.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
