Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow melting device which melts snow between railroad tracks.

[0002]

2. Description of the Related Art Conventionally, various snow melting apparatuses have been proposed for melting snow in the vicinity of a branch point (point) of a railway.

However, even with the snow melting apparatuses proposed so far, it is the current situation that good snow melting cannot be expected with respect to the snow carried by the front end of the train in an integrated manner.

[0004] For example, the snow-melting devices up to now have only melted snow in the vicinity of the branch, and not in a certain range before and after the branch. Therefore, when a train or a snow removing train runs on the track, the snow is not melted before and after the branch. There has been a problem that front ends of trains and snow-pulling trains collect and carry snow and new snowfall, and the snow is carried to a branching part and becomes so-called compacted snow, which disables the operation of the branching part. Since the inoperability of the bifurcation leads to a major accident, it is desired to solve this point.

SUMMARY OF THE INVENTION The present invention has a technical object to provide a snow melting apparatus which solves the above problems.

[0006]

The gist of the present invention will be described with reference to the accompanying drawings.

A track 1 installed on the left and right at predetermined intervals
A snow melting device that melts snow between 1 and a hollow body 4 of a desired length is formed in the vicinity of a branching portion 3 where the orbit 1 and 1 branch off. The heat source 6 is laid in the horizontal direction in an inclined state in the left-right direction, the heat source 6 is provided on the lower side of the hollow body 4 having the height, and the heat medium 7 which becomes a liquid at room temperature and becomes a gas when heated is enclosed in the hollow body 4. The present invention relates to a snow melting device.

[0008]

The lower side of the hollow body 4 is heated by the heat of the heat source 6,
The heat medium 7 stored on the low side of the hollow body 4 is vaporized by the heat and moves to the high side of the hollow body 4, and in the moving process, the heat medium 7 radiates heat to the snow on the hollow body 4. The snow accumulated on the hollow body 4 is melted, and conversely, the heat medium 7 is deprived of heat, condensed and liquefied, and is refluxed to the lower side of the hollow body 4, and this heat transfer cycle is repeated.

Therefore, even if a train or a snow removal train carries snow by its front end, there is no snow in front of the branching portion 3 due to the snow-melting action of the hollow body 4, so the carried snow is a hollow body without this snow. 4 and thus no snow is carried on the branch 3.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show one embodiment of the present invention.
This will be described below.

The drawing shows a case in which a plurality of rectangular hollow bodies 4 each having a length of 2 m and a width of 80 cm are fixedly fastened to a sleeper 9 by fasteners 8 at three places 20 m before the branch portion 3. Is shown. In addition, it is desirable to provide a snow melting device (not shown) at the branch portion 3.

The hollow body 4 has a structure in which compartments 5 are arranged side by side with a partition plate 10 at intervals of approximately 10 cm, and each compartment 5 is filled with a low pressure CFC gas as a heat medium 7. The heat medium 7 is not limited to chlorofluorocarbon gas, and any type of heat medium may be used as long as it can perform a heat exchange action. In addition, a small hole 11 is provided near the high side of the partition plate 10.
The small holes 11 keep the internal pressure of each compartment 5 uniform. Reference numeral 12 is a CFC inlet.

As shown in the figure, the hollow body 4 has a structure in which the interior of the hollow body 4 is partitioned by a partition plate 10 so that the compartments 5 are arranged side by side. You may form the hollow body 4 which arranged 5 in parallel.

Further, hot water is used as the heat source 6, and the hot water sent from the hot water supply unit 13 (boiler) is a main water supply pipe.
The water is sent by 14 and is introduced into the heat dissipation pipe 16 penetrating the inside of the hollow body 4 on the lower side through the branch pipe 15, and the return water pipe 17 is sent from the heat dissipation pipe 16 through the branch pipe 18, and this pipe is repeated. , At the end, since the branch pipe 18, the return water pipe 17, and the water supply main pipe 14 are connected to the return water main pipe 19, the used hot water that has been radiated is returned to the return water main pipe 19 and returned to the hot water supply unit 13. ..
As described above, the drawing employs the hot water circulation type heat source 6 that reheats and reuses used hot water. The heat source 6 is provided with a control unit for adjusting the amount of heat supplied.

The heat source 6 may have a structure in which a heating wire (heater) is simply arranged inside the lower side of the hollow body 4 without providing the various pipes shown in the drawing.

Reference numeral 2 is a connecting joint, 20 is a holding plate provided with an inclined surface for preventing snow carried by the front end of the train from entering the lower surface of the hollow body 4, and 21 is a heat insulating material.

Since the present embodiment has the above structure, the branch portion 3
Since snow in the vicinity of is evenly melted, for example, even if a train or a snow removal train runs and carries snow at its front end, between the tracks 1 and 1 about 20 m before the junction 3, Since the snow is melted by the hollow body 4, therefore, only snow is brought into the hollow body 4 having no snow, and the snow is not brought into the branch portion 3. Therefore, even if the train passes through the branch portion 3, The accumulation of snow on the bifurcation 3 is reliably prevented, and the bifurcation 3
The inoperable state of does not occur.

Further, the hollow body 4 of the snow melting device functions as a so-called heat pipe, and therefore, the heat pipe has the advantage that heat loss can be reduced by reducing loss of heat released to the outside.

Further, since the hollow body 4 used in this snow melting apparatus is partitioned by a plurality of compartments 5, as compared with the case where the chlorofluorocarbon gas is enclosed in a simple hollow box without the compartments 5,
In each of the compartments 5 in the hollow body 4, the chlorofluorocarbon gas is uniformly vaporized and liquefied and refluxed. Therefore, the heat medium 7 that is uniform as a whole of the hollow body 4 uniformly radiates heat to the snow on the hollow body 4. Therefore, uniform snow melting can be performed on the entire surface of the hollow body, and the internal pressure in each compartment 5 can be kept as uniform as possible by the small holes 11 of the partition plate 10 forming the compartments 5. Snow melting by the body 4 is performed uniformly.

The partition plate 10 forming the compartment 5 is
When the internal pressure of CFC gas is applied, it also serves to reinforce the hollow body 4 and imparts durability to the hollow body 4, so that it exhibits an excellent effect.

As described above, the present invention provides a snow melting device capable of reliably preventing snow accumulation on the branch portion of the track and reliably preventing the inoperability of the branch portion.
