Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vanishing YukiSo location for melts the snow line of railway.
[0002]
[Prior art]
For example, a sprinkler is often used as a snow removal device. This is done by installing sprinklers at intervals of several meters on header pipes arranged on both sides of railroad tracks, etc., using this sprinkler to sprinkle the water to melt the snow, and the snowmelt water after sprinkling flows into the drainage pit and further circulates. It is pumped to the pit, passed through a dust removal tank and a sedimentation tank, and stored in a water storage tank. The water in this water storage tank is sucked up and sprinkled again by a sprinkler. In this way, the water is circulated and used.
[0003]
However, such a snow melting facility with sprinkler sprinkling sprays water directly into the snow accumulating section, so there is a risk that the snow melting water may penetrate into the soil of the track and soften the ground, and corrosion such as rails, nails, and sleepers will occur. There is a risk of inviting. Furthermore, since the snowmelt water after watering is circulated and used, dust removal equipment is required.
[0004]
In contrast, there is a snow-dissipating heat radiator proposed in Japanese Patent Publication No. 6-76681 as a snow-dissipating panel that does not use water spray. This snow-dissipating heat dissipator has a substantially rectangular flat plate shape, a flat heat dissipating surface is formed on the upper surface, and a flow path through which warm water flows is formed immediately below. This flow path is formed by welding and fixing the upper surface of a thin plate with a groove formed by, for example, pressing a thin steel plate with a lower surface of a thin steel radiator plate. This flow path continues in a zigzag manner with a wide and shallow trapezoidal groove. A hole is opened at the bottom of both ends of the groove, and a hot water supply pipe and a discharge pipe are connected to the hole as a pipe connection port. Since this pipe connection port, hot water supply pipe and discharge pipe are provided on the lower surface of the radiator, the radiator keeps the temperature of the space in which it is installed and there is no fear of being exposed to the outside air. .
[0005]
[Problems to be solved by the invention]
Such a snow squeezing device having a snow squeezing heat radiator is used to melt snow accumulated on a railroad along a passage such as a railway. Before the morning train runs, remove the snow accumulated on the track due to snowfall at night with a Russell car and stack it on the snow-breaking device beside the track, and then flow the hot water through the snow-dissipating heatsink. Will melt on the heat sink.
[0006]
This snow squeezing device is also laid between the up and down lines in the section of the double track, but in that case, it is necessary to have a space between the up and down lines. For example, the snow-breaking device has a width of about 1500 mm.
[0007]
By the way, for maintenance of such a snow extinguishing device, it is necessary to lift the snow-dissipating heatsink and check the hot water supply and drainage piping and the piping of the connection part under it, but the width is 1500 mm In some cases, it weighs 150kg to 240kg, and the operator cannot easily lift the heatsink.
[0008]
In addition, a heat sink is attached to the upper surface of the snow-dissipating heatsink, and the snow piled up or piled up snow is melted on it. It may worsen or cause corrosion of the heat sink. However, since humans sometimes work on the heat sink, it is difficult to prevent the heat sink from being uneven when the width is 1500 mm as described above. Furthermore, since it is common to apply plating or the like to prevent corrosion of the thin steel plate, this plating treatment may cause plating distortion and unevenness.
[0009]
Therefore, in the present invention, a first object of the present invention is to provide a snow-dissipating heat dissipator that does not cause a puddle on the heat dissipating plate on the upper surface. Another object is to provide a snow extinguishing device.
[0010]
[Means for Solving the Problems]
The snow-dissipating heatsink used in the present invention has a heat sink made of a flat plate with a thin upper surface, a plurality of wide and shallow concave portions joined to the lower surface of the heat sink, and a wide width connecting adjacent portions of each row of the concave portions. that Yusuke and grooved plate having a groove portion formed of a shallow recess, and a pipe connection port provided at both ends of the wide, shallow flow path which is formed by a shallow groove in a continuous wide the grooved plate and the heat radiating plate .
[0011]
The snow extinguishing apparatus according to the present invention includes a plurality of snow extinguishing radiators arranged along a railroad line, etc., and the snow extinguishing radiator can be lifted from one end , a supply pipe for a heat medium such as hot water, and It is characterized in that the piping connection port of each snow-dissipating radiator is connected in parallel to the discharge pipe using a flexible pipe . Here, snow melting radiator is of 1 to 5 ° hot plate release is the horizontal, more preferably it is desirable to use those which is provided with a gradient of 1 to 2 °.
[0012]
[Action]
The snow-dissipating heatsink of the present invention has a thin heat sink made of a thin flat plate on its upper surface with a gradient with respect to the horizontal, 1-5 °, preferably 1-2 °. As a result of plating, water does not collect even if warping or unevenness is generated on the surface due to plating distortion, and there is no risk of corrosion due to water accumulation. At the same time, there is no risk of a decrease in snow melting effect due to accumulated water. Further, since the slope is provided, the melted water is removed without accumulating on the radiator, so that the unmelted snow always comes into contact with the radiator plate and the snow melting effect is enhanced.
[0013]
In addition, regarding the numerical value of the above gradient, if it is an inclination of 1 ° or less, it is not preferable because water still tends to accumulate. On the other hand, if it is 5 ° or more, the gap between the snow-dissipating heat radiators arranged in parallel is widened, and it is not preferable because it becomes slippery when a person gets on. For these reasons, it is usually desirable to set the angle to 1 to 2 °.
[0014]
Moreover, since this heat radiator is arranged in a plurality of rows when arranged along a passage such as a railway, the width of each heat radiator can be reduced. As described above, since the width of the snow-dissipating heat radiator used in the snow extinguishing device can be reduced, warpage and unevenness of the heat-dissipating surface that may occur during manufacturing can be reduced accordingly, and a water pool is generated. The fear can be reduced by adding the above gradient.
[0015]
In addition, since the width can be reduced, the weight per one snow-dissipating heatsink can be reduced by that much, and the snow-dissipating heatsink can be lifted from one end, and its piping connection port Is connected in parallel to the heat medium supply pipe and the discharge pipe using a flexible pipe, so that it becomes easy for an operator to handle the radiator during maintenance.
[0016]
However, on the other hand, if the heat sink for snow extinguishing is divided and made smaller, when a heat medium such as hot water is passed through the heat radiator in turn, the heat medium gradually decreases in temperature and the heat radiator connected to the rear side Although the snow-dissipating effect is inferior, in the present invention, the piping connection ports of the respective snow-dissipating radiators are connected in parallel to the heat medium supply pipe and the exhaust pipe. The temperature can be made substantially uniform.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the snow-dissipating heat radiator and the snow-dissipating device using the same according to the present invention will be described below with reference to FIGS. FIG. 1 is a cross-sectional view showing a state in which a snow removal device using a snow-dissipating heat radiator of the present invention is laid on the side of a passage (track) such as a railway, and FIG. It is a top view which shows the state which arranged the stand, The upper side has shown the figure seen from the lower surface of the heat sink so that the inside can be understood. FIG. 3 is a lower side view of FIG.
[0018]
In FIG. 1, snow removing devices 13 and 14 are laid on both sides of the two tracks 12 and on the center thereof on the road bed 11. These snow-melting devices 13 and 14 comprise a snow-dissipating heat radiator 2 as shown in FIGS. 2 and 3, and the snow-storing devices 13 on both sides of the two tracks 12 are compared to the central one. Since the width is narrow, the right half or left half of the snow-dissipating heat radiator 2 shown in FIGS. 2 and 3 is laid in a line. However, it may be used in two or three rows where the width is wide or other necessary. On the other hand, since the snow-removing device 14 at the center of the two tracks is wide, as shown in FIGS. 2 and 3, the snow-dissipating heat radiator 2 is laid in parallel in two rows. However, in this case as well, it may be used in a wider area or if necessary in more than two rows.
[0019]
Now, the width for installing the snow removing device 14 between the two tracks 12 is normally 1300 mm, about 1500 mm at a wide place, and the side part of the track is about 1200 mm. Here, a snow-dissipating device with a width of 1,500 to 1,300 mm and a length of 5500 mm is used as a snow-dissipating device, and SPHC-P material (thickness 2.3 mm) is used as a heat-dissipating plate. / Sheets. However, as shown in FIGS. 2 and 3, when the width of the radiator is reduced so that the snow-dissipating radiators 2 are arranged in two rows, the weight is about 75 kg / sheet, even if it is a regular length. It becomes. Also, as shown in FIG. 2, if the length is half of the standard length, it becomes 1/4 of 150 kg and is easy to handle.
[0020]
Further, a supply pipe 4 and a discharge pipe 5 for a heat medium such as hot water supplied to the snow-dissipating radiator 2 are laid under the snow-eliminating devices 13 and 14 as shown in FIG. Therefore, during these periodic maintenance inspections and abnormalities, it is necessary to lift the snow-dissipating radiator 2, but at this time, the snow-dissipating radiator 2 opens from both sides as indicated by broken lines in FIG. Therefore, the lifting weight is relatively light, and maintenance of the supply pipe 4 and the discharge pipe 5 can be easily performed. In the figure, 15 is a water supply / drainage pipe, and 16 is a support member when the heat sink is opened.
[0021]
Next, the snow-dissipating heat radiator 2 of the present invention will be described with reference to FIGS. FIG. 2 is a plan view of two snow-dissipating heat radiators 2 arranged in succession vertically and horizontally. Since the length of two radiators connected in the length direction is about 5500mm, which is the standard length, one is about 2750mm. In addition, since the width is 1200 to 1500 mm when the two are connected in the width direction, the width is 600 to 750 mm, which is half of that.
[0022]
Here, each of the snow-dissipating heat radiators 2 has a thin heat-radiating plate 21 on its upper surface, and the upper portion of FIG. 2 shows a state where the heat-dissipating device is viewed from the bottom in order to help understanding. That is, a flow path 22 through which a heat medium such as warm water flows is formed immediately below the heat radiating plate 21, and a heat insulating material is stacked below the flow path 22 as necessary to prevent heat radiation from the lower side. It is possible to do so.
[0023]
The flow path 22 is formed on the lower surface of a heat sink 21 obtained by hot-dip galvanizing a rectangular thin plate made of steel, for example, and on the upper surface of a grooved steel plate in which grooves are formed in a rectangular thin plate, for example, a thin steel plate by pressing or the like. It is fixed by welding. As shown in FIG. 2, the groove 22 of the grooved steel plate is composed of a plurality of vertical rows of concave portions 221, and concave portions 222 that connect the respective rows of the concave portions to each other. It reciprocates up and down between the both ends of a grooved steel plate. The cross-sectional shape of the recess is, for example, a trapezoid with a wide width and a shallow depth. And the hole which penetrates a grooved steel plate is opened in the bottom of the both sides of this groove, a short pipe is fixed to the lower surface of the through-hole part of this grooved steel plate by welding, and piping parts, such as a valve, to this short pipe Are connected to the pipe connection ports 23-26.
[0024]
Next, referring to FIG. 3, the snow-dissipating radiator is installed on a panel support plate 31 on the frame 3 to which a supply pipe 4 and a discharge pipe 5 of a heat medium such as hot water are attached. Thus, here, the pipe connection ports 23 and 25 of the radiator 2 are the two lead pipe connection ports 28 and 28 provided in the supply pipe 4, and the pipe connection ports 24 and 26 are the two pipe connections 24 and 26 provided in the discharge pipe 5 . The drawer pipe connection ports 27 and 27 are connected by a flexible pipe 29 made of resin or the like that is curved . As described above, the supply pipe 4 and the discharge pipe 5 of the frame 3 are each provided with a flexible pipe lead-out port for each snow-dissipating radiator 2, and the flexible pipe or the like is used for the inlet and the outlet. Each is connected in parallel. Reference numeral 6 denotes a return pipe collecting pipe for making the pressure loss constant.
[0025]
In the example shown in FIG. 3, the spacer 32 is inserted in the approximate center of the panel support plate 31, and the radiator is provided with a gradient with respect to the horizontal, about 1 to 5 °, in this embodiment about 2 °, Both sides are lowered. Therefore, even if the heat sink on the upper surface of the radiator has a slight warp or unevenness, there is no risk of water accumulation by providing such a gradient.
[0026]
【Example】
In order to see the snow melting effect of the heat sink for snow removal of the present invention, a snow melting experiment was conducted by passing hot water of about 6 ° C. through the heat sink at 20 liters / minute with a snow cover of 20 to 45 cm on the heat sink. Went. As a result, in this example, the snow on the heat sink almost melted in about 1 hour, and the water temperature at the outlet was 2 to 3 ° C. The snowfall during that time was several cm / hour. In addition, the same experiment was conducted with hot water of about 3 ° C., and in this case, the snow melting effect was also observed. Thus, it was confirmed that the snow-dissipating heat radiator of the present invention has a snow-melting effect even in warm water of 10 ° C. or less.
[0027]
【The invention's effect】
Since the heat sink for snow extinguishing of the present invention is inclined with respect to the horizontal of the heat sink, water does not collect even if warpage or unevenness occurs on the heat sink, there is no risk of corrosion due to the water pool, Moreover, there is no possibility that the snow melting effect due to freezing of the accumulated water is reduced. In addition, since it has a slope, it can prevent snow accumulation and has a good snow melting effect.
[0028]
Further, since the radiators are arranged in a plurality of rows along the passage, the width of each radiator can be reduced, so that the unit weight of the radiator is reduced and handling during maintenance is good. Furthermore, since the warm water flow to the snow-dissipating heat radiator is arranged in parallel, the temperature of all the heat radiators can be made substantially uniform, and the snow melting effect is improved.
