Abstract
The utility model discloses a thermal probe for pipelines, which is formed by a condensation section and an evaporation section. The condensation section is arranged in the atmosphere and the evaporation section is arranged in the frozen soil. The evaporation section is formed by two semicircular pipe bodies. Both the two semicircular pipe bodies of the evaporation section are connected with the lower end of the condensation section so as to form a ring. The center line of the ring coincides with the center line of the pipeline. The thermal probe is simple in structure. When the thermal probe is in use, the ring of the evaporation section of the thermal probe is first sleeved onto the pipeline and then is buried in the frozen soil. The heat in the frozen soil surrounding the pipeline is absorbed by the evaporation section and then is transmitted to the condensation section. Finally, the heat is emitted to the atmosphere. Therefore, the thermal stability of the frozen soil surrounding the pipeline is ensured. The thermal probe is suitable for all kinds of pipelines buried in frozen soil.
Description
Technical field the utility model relates to a kind of hot pin, the hot pin that especially uses in pipeline foundation.
Background technology is many places in the world, pass the gas pipeline in frozen soil location, all can more or less be subjected to the adverse effect of frozen soil.Frozen soil freezed just as ice in dead season, along with the reduction volume of temperature expands, built the frozen soil extruding that the pipeline in the frozen soil will " be got fat " in; To summer, the frozen soil volume-diminished of thawing, pipeline can become flexible again, tilt.The freezing and melt repeatedly alternately of frozen soil occurs, and will the safety of pipeline, railway, highway be threatened.
Hot pin is centreless gravity type heat pipe or thermal siphon again, is made up of the steel pipe of a sealing, and the inside is filled with liquid nitrogen or other working medium, and radiator shutter is equipped with on the top of steel pipe, is referred to as condensation segment, places atmosphere; The bottom of steel pipe is imbedded in the ground ever-frozen ground, is called evaporator section.When having the temperature difference, the heat absorption of the liquid nitrogen of evaporator section flashes to gas, and the pipe internal pore rises to condensation segment in draught head effect lower edge, is condensed into liquid, and under action of gravity, flows down along tube wall.Circulation is transferred to the heat in the stratum in the atmosphere and so forth, thereby the ground temperature of reduction ever-frozen ground melts to prevent ever-frozen ground, thereby reaches the purpose of stable pipeline, railway, highway foundation.
It is circular that the cross section of pipeline is generally.Pipeline is imbedded in the frozen soil usually, exists than big difference with the structure of railway, highway foundation.Therefore, the hot pin that uses on railway, the highway foundation is used on the pipeline foundation, does not reach desirable heat absorption and radiating effect.
Chinese patent CN201443035U number disclosed " the high asphalt road of a kind of road surface heat stability intensity " patent (application number: 200920016848.8), be on the roadbed of asphalt road, to be provided with hot pin, this hot pin evaporator section is positioned at the pitch roadbed, and center line and horizontal direction are 5 °～8 ° angle of slope, and this hot pin condensation segment then is positioned at pitch roadbed lateral surface.Chinese patent CN2846509 number disclosed " protection bar low temperature hot-bar " patent (application number: 200520145957.1), being located at the condensation segment that the low temperature hot-bar in frozen earth roadbed bassets bends to horizontal direction, become the special-shaped hot pin about 5 °-15 ° with horizontal sextant angle, this height and the corresponding low temperature hot-bar sweep of guardrail height, its end links to each other with adjacent low temperature hot-bar by connector.The weak point of these two patents is: improve adapting to different applied environments though can structurally do some, but still can not directly be applied on the pipeline foundation.
The summary of the invention the purpose of this utility model is exactly that a kind of hot pin that is used for pipeline will be provided, and makes the safety that hot pin more can the service conduit basis.
In order to achieve the above object, a kind of hot pin that is used for pipeline that the utility model provides is made of condensation segment and evaporator section, and wherein, condensation segment places atmosphere, and evaporator section places frozen soil; Evaporator section is made up of two semicircular bodys; Two semicircle bodys of evaporator section be connected the lower end of condensation segment jointly and form circular, the center line of annulus and the central lines of pipeline.When the utility model uses, the annulus of hot pin evaporator section is enclosed within imbeds again on the pipeline in the frozen soil earlier, evaporator section is transferred to condensation segment after with the heat absorption in the frozen soil around the pipeline, is dispersed in the atmosphere again, guarantees the thermally-stabilised of frozen soil around the pipeline.
A kind of hot pin that is used for pipeline that the utility model provides has positive effect: evaporator section is made up of two semicircular bodys, two semicircle bodys of evaporator section are connected the lower end of condensation segment jointly and form circular, the center line of annulus and the central lines of pipeline, simple in structure; First annulus with the hot pin evaporator section is enclosed within on the pipeline and imbeds in the frozen soil again during use, evaporator section is transferred to condensation segment after with the heat absorption in the frozen soil around the pipeline, be dispersed into again in the atmosphere, guarantee the thermally-stabilised of frozen soil around the pipeline, be applicable to that all imbed the pipeline in the frozen soil.
Description of drawings the utility model will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:
Accompanying drawing 1 expression schematic diagram of the present utility model.
Structure shown in the accompanying drawing 1 comprises: condensation segment 1, evaporator section 2, pipeline 3, frozen soil 4.
A kind of hot pin that is used for pipeline that specific embodiment the utility model provides is made of condensation segment 1 and evaporator section 2, and wherein, condensation segment 1 places atmosphere, and evaporator section 2 places frozen soil 4; Evaporator section 2 is made up of two semicircular bodys; Two semicircle bodys of evaporator section 2 be connected the lower end of condensation segment 1 jointly and form circular, the central lines of the center line of annulus and pipeline 3.When the utility model uses, the annulus of hot pin evaporator section 2 is enclosed within imbeds again on the pipeline 3 in the frozen soil 4 earlier, evaporator section 2 is transferred to condensation segment 1 after with the heat absorption in the frozen soil 4 around the pipeline 3, is dispersed in the atmosphere again, guarantees the thermally-stabilised of frozen soil 4 around the pipeline 3.
The utility model protection domain relates to all changes form recited above.
