Abstract
The utility model provides an anti-freezing device for iron tower heat pipes of power transmission-transformation lines. The ground at the root of an iron tower is provided with a gravity heat pipe to an underground heat source, and the upper part of the heat pipe is divided into a plurality of branches which are respectively and closely connected with a main stress rod of the iron tower. The underground heat source can continuously radiate heat to the iron tower along the heat pipe, which can ensure that ice and snow on the iron tower in winter is in a melted state and then ensure the normal operation of the power transmission-transformation lines.
Description
Technical field
The utility model relates to anti-freezing device in iron tower for power transmission and transformation line winter, particularly a kind of can be with attached to the anti-freezing device of the heat pipe of the ice dissolution on the iron tower for power transmission and transformation line.
Background technology
In high voltage power transmission and transforming line steel tower design, iron tower can bear advocates to consider the pulling force of iron tower two ends high voltage power transmission and transforming line and the side force that strong wind blows to iron tower.If consider to be frozen in the external force that causes on the iron tower because of ice and snow, the designed iron tower that goes out is unusual waste material just, and the thickness that ice and snow freezes can not normally estimate, can not guarantee that the bending accident does not appear in iron tower under extreme weather conditions.So, just do not consider that ice and snow is frozen in the power on the iron tower in the high voltage power transmission and transforming line steel tower design at present.But under extreme weather conditions, make ice and snow be frozen on the iron tower as a snow calamity at 2008 beginning of the years, the stressed of iron tower is multiplied, cause the iron tower bending, power transmission and transformation line is broken, and along the line the power failure caused the tremendous economic loss.Therefore seeking a kind of device does not freeze the high voltage power transmission and transforming line steel tower all the year round winter just to seem and is necessary very much.
Summary of the invention
The purpose of this utility model provides a kind of simple underground heat that utilizes and melts the anti-freezing device of heat pipe of ice and snow on the iron tower, thereby guarantees the normal operation in winter of high voltage power transmission and transforming circuit.
The purpose of this utility model is realized by following scheme:
Gravity assisted heat pipe 2 is set to underground thermal source 3 places on iron tower 1 root ground, heat pipe 2 tops closely link to each other with iron tower 1.
The top of above-mentioned gravity assisted heat pipe 2 is divided into a plurality of branches, and the force rod with iron tower 1 closely links to each other respectively.
The utility model is simple, has solved winter ice and snow under extreme weather conditions and has been frozen in a difficult problem that makes the stressed increase of iron tower on the iron tower, causes the iron tower bending.It can make iron tower not influenced by ice and snow, thereby it is stressed to reduce iron tower, improves iron tower useful life, is a kind of effective high voltage iron tower anti-freezing device in winter.
Description of drawings
Accompanying drawing is a facade structures schematic diagram of the present utility model.
Embodiment
Above accompanying drawing is disclosed to be the structure of an embodiment of the present utility model.
Consult accompanying drawing, 1 is iron tower among the figure, and the high voltage power transmission and transforming circuit is used; 2 is gravity assisted heat pipe, adopts the common steel tube manufacturing, sealed at both ends, and inside is for negative pressure and fill working media, and its capacity of heat transmission surpasses existing known metal, and its shape can be made according to the iron tower shape; 3 are the thermal source of below ground, inexhaustible.
Insert heat pipe 2 to thermal source 3 places at iron tower 1 root below ground, heat pipe 2 upper ends are closely linked to each other with the main force rod in iron tower 1 upper end, utilize heat pipe 2 heat conduction fast, conduct uniform characteristics, can rapidly underground heat be taken out the main force rod that reaches iron tower 1, make attached to the knot of the ice on the iron tower 1 and melt.
Be the anti-freezing embodiment of certain iron tower heat pipe below: iron tower is four main force rods; Extremely main force rod top is 30 meters from ground, and it is anti-freezing to design the 15 meters needs in main force rod upper end, gets below ground by exploration and is geothermal heat source 3 for 5 meters, and heat pipe 2 lower ends are designed to 200 millimeters of diameters, and length is 20 meters; The upper end is designed to 50 millimeters of diameters, and length is 15 meters, and quantity is four.The place of 5 meters of below grounds is inserted in gravity assisted heat pipe 2 lower ends, and the upper end closely links to each other with main force rod (as welding).
The insulation measure is taked in gravity assisted heat pipe 2 lower ends, makes heat be delivered to heat pipe 2 upper ends quickly and efficiently, thereby it is hot maximum that iron tower 1 main force rod is got.
If unspecified content is arranged, should be the known technology that maybe should know of professional and technical personnel in more than narrating, do not repeat them here.
Claims (2)
1. an iron tower for power transmission and transformation line heat pipe is prevented freezing device, it is characterized in that: gravity assisted heat pipe (2) to underground thermal source (3) is set on iron tower (1) root ground locates, heat pipe (2) top closely links to each other with iron tower (1).
2. by the anti-freezing device of the described iron tower for power transmission and transformation line heat pipe of claim 1, it is characterized in that: the top of above-mentioned gravity assisted heat pipe (2) is divided into a plurality of branches, and the force rod with iron tower (1) closely links to each other respectively.
