Abstract

PURPOSE:To improve the snow melting faculty by suppressing the exfoliation between one side of a heat pipe and a heat radiation panel due to vibration by forming an accommodating groove which accommodates a part on the other side of a heat pipe formed on the heat radiation panel, in thermal contact with the heat radiation panel and supports said part in vibrationproof manners. CONSTITUTION:One edge side 9a of a heat pipe 9 is heated by the heat in the soil 2, and the working fluid in the heat pipe 9 is vaporized, and transferred to the other side 9b of the heat pipe 9. Since the temperature of a heat radiation panel 10 arranged in a snow storage groove 7 is lower than that of the soil 2, the vapor of the working fluid is condensed and liquefied, and liberates the condensation latent heat into the hat radiation panel 10. Further, the heat radiation panel 10 is heated by the condensation latent heat, and the temperature is raised, and the liquefied working fluid is returned to one side 9a of the heat pipe 9. Through the natural repetition of the above-described operations, snow 8 is melting-processed, and the heat transmission area is increased by an accommodation groove 11 between the other side 9b of the heat pipe 9 and the heat radiation panel 10, and the snow melting faculty is improved drastically.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a snow melting device that melts snow that has been removed by a train on an elevated track and accumulated in a snow storage groove, thereby smoothing the running of the train. .

[Conventional technology]

For example, a conventional snow melting device is disclosed in Japanese Utility Model Application Publication No. 56-68017, and this device is used to melt snow accumulated in a snow storage groove installed next to an elevated track of an elevated bridge. 5 and 6, FIG. 5 is a vertical cross-sectional view, and FIG.
The figures each show a cross-sectional view, and in each of these figures (
1) is a pier whose foundation is buried in soil (2), (8)
is a viaduct provided on the upper part of the pier (1), and has a viaduct side wall (3a) and a viaduct floor (3b). (4)
is an elevated train track laid on the viaduct floor (3b), and consists of sleepers (5) and rails (6). (
7) is an elevated track (4) snow storage grooves installed parallel to the side;
(8) is the snow that was removed by the train and accumulated in the snow storage ditch (7), (9) is - Case (9a) is buried in the soil (2), and the other side (9b) is the snow storage on the viaduct (3) This is a heat pipe that is buried in the lower part of the bottom of the groove (7) and has a working fluid such as water or ammonia sealed inside.

Next, the operation will be explained. When it snows in the winter, it is necessary to remove the snow that has accumulated on the train tracks to ensure smooth running of the train. If the track is installed on the viaduct (8), it is difficult to remove snow from the viaduct (8) due to the side walls (3a) of the viaduct.
Snow storage groove (7) parallel to the elevated track (4) on the viaduct floor (3b)
), the removed snow (8) is accumulated and stored in this snow storage groove (γ), and this snow (8) is transferred to a heat pipe (9).
) is melted by the heat transport effect. That is, when the temperature on the other side (9b) of the heat pipe (9) becomes lower than the temperature on one side (9a) of the heat pipe (9), heat transport occurs. For example, in snowy conditions, the temperature inside the snow storage groove (γ) is about 00C. On the other hand, the temperature in the soil (2) is on average 13 to 158°C even in winter when using the underground method at -glOm.
It is about 0. The heat in this soil (2) heats one side (9a) of the heat pipe (9), causing the heat pipe (9) to heat up.
The working fluid in ) is vaporized, removes the amount of heat in the soil (2) as latent heat of vaporization, and moves through the heat pipe (9) to the other side (9b) of the heat pipe (9).

The steam of the working fluid that has moved to the other side (9b) of the heat pipe (9) is condensed and liquefied because the temperature on the snow storage groove (γ) side is lower than that on the soil (2) side, and condenses on the snow storage groove (7n side). Releases latent heat.The liquefied working fluid flows along the inner wall surface of the heat pipe (9) and flows back to one side (9a) of the heat pipe (9).By naturally repeating the above operation, the soil +21 can transport heat to the snow storage groove (7) side and heat the inside of the snow storage groove (7) to 0°C or higher,
The snow (8) accumulated in the snow storage groove (γ) is being melted.

[Problem to be solved by the invention]

However, in the conventional device described above, since the viaduct (8) is vibrated by the train running on the elevated track (4), the other side (9b) of the heat pipe (9) is in the concrete deep below the bottom of the snow storage groove (A). It was necessary to bury it in the ground, making the burying work extremely troublesome. In addition, snow storage ditch (
γ) The other side (9b) of the heat pipe (9) is placed at a far distance from the bottom of the snow storage groove (A).
This was done through thick concrete, resulting in poor heat transfer efficiency and poor snow melting performance. As a result, load response was poor, and snow melting performance could not be demonstrated promptly when required.

This invention was made in order to solve the above-mentioned problems, and an object thereof is to obtain a snow melting device with high snow melting performance.

[Means to solve the problem]

The snow melting device according to the present invention includes a snow storage groove for storing snow removed by trains on the elevated track in an elevated track tank of an elevated bridge, and electricity is distributed to the other side of the heat pipe within the storage groove. A heat dissipation panel is provided on which the lightning is deposited, and an accommodation groove is formed on the heat dissipation panel to house a part of the other side of the heat pipe in thermal contact with the heat dissipation panel for seismic support. .

[Effect]

In the snow melting device of the present invention, heat is efficiently transferred to the heat dissipation panel from the other side of the heat pipe housed in the accommodation groove formed in the heat dissipation panel and disposed in the storage groove, and snow accumulated on the heat dissipation panel is removed. Thaw promptly. Moreover, the other side of the heat pipe is seismically supported by the heat dissipation panel by the accommodation groove, and separation of the other side of the heat pipe and the heat dissipation panel due to vibrations caused by trains running on the elevated track is prevented.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In Figures 1 to 3, (1) is a bridge pier, (8) is an elevated bridge, (3b) is an elevated bridge floor, (4) is an elevated track, (6) is a sleeper, (6) is a rail, (7) is a snow storage groove, (8) is snow, (9) is a heat pipe, and the other side (9b) is arranged in the snow storage groove (7). α (to) is a heat dissipation panel installed in the snow storage groove (γ), and snow is accumulated on this heat dissipation panel αO). συ is formed on the heat dissipation panel αO) and on the other side of the heat pipe (9) (
9b) is housed in thermal contact with the heat dissipation panel α0 for seismic support, and increases the heat transfer area between the other side (9b) of the heat pipe (9) and the heat dissipation panel α0. This improves snow melting performance and prevents the other side (9b) of the heat pipe (9) from peeling off from the heat dissipation panel (toward) due to vibrations caused by trains running on the elevated track (4).

Next, the operation will be explained. When it snows in winter, snow accumulates on the elevated train tracks (4) and on the heat dissipation panels α arranged in the snow storage grooves (γ). The snow on the elevated track (4) is removed by the rotary car or the lead train (not shown) running on the rail I6) and deposited on the heat dissipation panel α in the snow storage groove (7). 2) One side (9a) of the heat pipe (9) is heated by the heat inside, and the working fluid inside the heat pipe (9) is vaporized and released into the soil (
The heat pipe (9) disposed in the lightning storage groove (A) passes through the heat pipe (9) and absorbs the heat amount of 2) as evaporative latent heat.
) to the other side (9b). The steam of the working fluid that has moved to the other side (9b) of the heat pipe (9) flows into the snow storage groove (γ
Since the temperature of the heat dissipation panel αQ disposed in the lightning storage groove (γ) is lower than that of the soil (2), the heat dissipation panel αQ condenses and liquefies and releases condensed latent heat to the heat dissipation panel α [ disposed within the lightning storage groove (γ). This condensed latent heat heats the heat dissipation panel and raises its temperature. The liquefied working fluid flows along the inner wall surface of the heat pipe (9) and returns to one end (9a) of the heat pipe (9). By repeating the above operations naturally, soil (2
) was efficiently transported to the heat dissipation panel through the heat pipe (9), and the heat dissipation panel α was heated to 0°C or higher, and deposited on the heat dissipation panel αQ in the snow storage groove (γ). Melt the snow (8). Moreover, the heat transfer area between the other side (9b) of the heat pipe (9) and the heat dissipation panel αC is increased by the accommodation groove aυ, and the snow melting performance thereof can be significantly improved.

Furthermore, when a train runs on the elevated track (4), the elevated track (
8) vibrates, but the other side (9b) of the heat pipe (9)
) was seismically supported by the accommodation groove 0υ formed in the heat dissipation panel αQ, so that the other side of the heat pipe (91
b) is prevented from peeling off from the heat dissipation panel, and stable snow melting performance against vibrations can be exhibited.

In addition, as shown in Fig. 4, an accommodation groove αυ is formed on the upper side of the heat dissipation panel (to), and a heat pipe (9) is placed in the accommodation groove αυ.
It is also possible to adopt a structure in which the other side (9b) is arranged, and the same effect as in the above embodiment can be obtained.

As described above, the other side of the heat pipe is not buried in the concrete of the viaduct, but is placed in the lightning storage trench, which simplifies the heat pipe installation work and allows indirect melting through the concrete. Instead, the melting process is performed directly on the heat dissipation panel, resulting in extremely high snow melting performance. As a result, load responsiveness is improved and snow melting performance can be quickly and adequately demonstrated when necessary.

Of course, one side of the heat pipe may be directly or indirectly connected to hot water.

〔Effect of the invention〕

As explained above, this invention increases the heat transfer area between the other side of the heat pipe arranged in the snow storage groove and the heat radiation panel, so that heat can be efficiently transferred from the other side of the heat pipe to the heat radiation panel. Therefore, the snow accumulated on the heat dissipation panel can be directly melted, and a snow melting device with high snow melting performance and quick response can be obtained. In general, by earthquake-proofing the other side of the heat pipe in a storage groove formed in the heat dissipation panel, it is possible to prevent the other side of the heat pipe from separating from the heat dissipation panel due to vibrations caused by trains running on elevated tracks. , it can demonstrate stable snow melting performance against vibrations.
