Description

  The present invention relates to a snow melting device that melts snow accumulated on a roof and drops it along an inclined surface of the roof.

  Currently, in snowy regions, snow melting devices that melt the snow on the roof and drop it onto the ground are used. As such a snow melting device, for example, a flat snow melting panel with a built-in heater is laid on the entire roof surface, or as shown in FIG. An apparatus has been proposed in which water vapor or the like is jetted to melt snow, and the melted snow is slid onto the ground and dropped (Patent Document 1, Patent Document 2, etc.).

  If such an apparatus is used, the snow on the roof can be melted by the heat from the snow melting panel or the hot water or water vapor ejected from the hole of the water flow pipe 59, and humans bother to climb on the roof and drop the snow. It is not necessary to perform such work.

  However, even when the snow on the roof is melted using such a snow melting device, the following problems occur.

  That is, in the case where a flat snow melting panel is provided on the entire surface of the roof as in the former case, it is necessary to attach the snow melting panel to the entire surface of the roof, which is not only costly but also takes time to install. End up.

  In addition, in the snow melting apparatus as shown in Patent Document 1 or Patent Document 2 described above, the introduction cost can be greatly reduced. However, in such a snow melting apparatus, hot water or water is not supplied from the hole provided in the water flow pipe 59. Since water vapor is ejected, only the snow near the hole can be melted. On the other hand, when melting snow on the roof using such a device, the pitch of the holes must be shortened to melt the snow as much as possible. If the length is shortened, the pressure of hot water or water vapor ejected from each hole is reduced, and it becomes impossible to melt snow far away.

  Furthermore, in such an apparatus such as Patent Document 1 and Patent Document 2, when hot water or water vapor is jetted downward from a water pipe arranged at the top of the roof, the pressure causes the snow near the lower end of the roof. Can not be melted and the upper snow is blocked by the lower snow that could not be melted, and it becomes impossible to drop the snow by its own weight.

  Therefore, the present invention has been made paying attention to the above-mentioned problem, and it can melt the snow accumulated on the roof as much as possible, and can also remove the snow by its own weight. The purpose is to provide.

  That is, in order to solve the above-mentioned problem, the present invention provides a snow melting device for melting snow accumulated on a roof having an inclined surface, and a water pipe having a hole portion disposed on the roof and for ejecting hot water or water vapor, A plate-like diffusion prevention plate for preventing the vertical diffusion of hot water or water vapor ejected from the hole of the flowing water pipe and diffusing in the left-right direction is provided.

  With this configuration, the diffusion prevention plate can prevent the hot water and water vapor from diffusing in the vertical direction. It can be melted. Further, the snow accumulated on the diffusion prevention plate can be melted by the heat transmitted to the diffusion prevention plate, and the snow on the snow can be dropped.

  In such an invention, the diffusion prevention plate is provided between the upper and lower surfaces of the flowing water pipe.

  In this way, even when hot water or water vapor is ejected to a waved portion such as a roof tile, a diffusion prevention plate is provided on the lower side of the water flow pipe, so the diffusion prevention plate is evenly distributed. Hot water and water vapor can be ejected from the tip portion of the glass.

  Further, the water pipe is arranged along the inclination direction of the roof.

  In this way, since the water pipes are arranged along the inclination direction of the roof (that is, the vertical direction), all the snow accumulated in the vicinity of the diffusion prevention plate can be melted along the vertical direction. The snow can be dropped first from the part.

  In addition, the water flow pipes are provided in the inclination direction of the roof and the left and right direction of the uppermost part of the roof, and hot water or water vapor is ejected along the right and left direction and the inclination direction of the roof.

  If it does in this way, while melting all the snow which piled up on the roof along the inclination direction, the melted snow can also be pushed down by the hot water and water vapor spouted from the upper direction.

  According to the present invention, in a snow melting device for melting snow accumulated on a roof having an inclined surface, a water pipe having a hole portion disposed on the roof and ejecting hot water or water vapor, and a hole portion of the water pipe A plate-shaped diffusion prevention plate is provided to prevent the sprayed hot water or water vapor from diffusing in the vertical direction, so that the diffusion of the hot water and water vapor in the vertical direction is prevented by the diffusion prevention plate. Thus, it is possible to melt the snow entirely by ejecting hot water or water vapor in the left-right direction from the front end of the diffusion prevention plate. Further, the snow accumulated on the diffusion prevention plate can be melted by the heat transmitted to the diffusion prevention plate, and the snow can be dropped.

Schematic diagram of a conventional snow melting device

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, the snow melting device 1 in this embodiment is detachably mounted on a roof 9 having an inclined surface, and includes a heating device 2 that heats water and its heating. A flowing water pipe 5 that guides hot water or water vapor heated by the device 2 to the roof 9 side, and a hole 6 (see FIG. 3) provided intermittently in the flowing water pipe 5 attached on the roof 9. Characteristically, the diffusion prevention plate 8 is attached so as to be sandwiched above and below the water flow pipe 5. And by attaching diffusion prevention board 8 up and down in this way, the hot water and water vapor which diffused radially from hole 6 are disperse | distributed by the diffusion prevention board 8 in the left-right direction, and it is made to eject uniformly from the front-end | tip part. It is a thing. Hereinafter, the snow melting apparatus 1 in this Embodiment is demonstrated in detail.

  First, as shown in FIG. 2, the heating device 2 includes an oil tank 3 that stores oil 31 and a heater 4 that is provided inside the oil tank 3. A flowing water pipe 5 connected to a household water pipe is passed through the oil tank 3, and the oil 31 is heated to a high temperature by the heater 4, and the water in the flowing water pipe 5 is indirectly heated by the heat. I am doing so. When the water in the water pipe 5 is heated by the oil tank 3, the water pipe 5 is formed thin and meandered in the oil 31 so that the water is heated to hot water or steam as efficiently as possible. Keep it like that. Here, in the case where the water in the water flow pipe 5 is heated, in this embodiment, the water is heated to a high temperature until it becomes water vapor, expanded to about 1700 times, and the water vapor is discharged. However, it may be discharged in the state of hot water.

  On the other hand, the flowing water pipe 5 is configured so that water passed from a household water pipe can be guided to the oil tank 3 and heated there to guide water vapor to the upper side of the roof 9. About the part to the roof 9 in this water pipe 5, the heat retention member is wound so that the heated water vapor may not be cooled by outside air, or the water pipe 5 itself is made of a heat insulating material. Like that. Further, the flowing water pipe 5 provided on the roof 9 is attached along the vertical direction which is the inclination direction of the roof 9. At this time, in the case where the roof 9 is made of the tile 91 and there are irregularities, the water pipe 5 is positioned above the convex portion so that the water vapor is ejected far away. Keep it. When the water pipe 5 is attached to the roof 9, the upper end of the roof 9 is fixed with a fixture 7 or the like at the uppermost part of the roof 9 so that the water pipe 5 is not dropped from the roof 9.

  As shown in FIG. 3 and FIG. 4, holes 6 for ejecting water vapor and the like are intermittently provided on both the left and right side surfaces of the water flow pipe 5 provided on the roof 9, and the water vapor is generated therefrom. Is ejected at high pressure. In general, when water vapor is ejected at a high pressure, water vapor is diffused radially from the hole 6 (that is, in the vertical and horizontal directions), and only snow located in the vicinity of the hole 6 can be melted. . Therefore, the plate-like diffusion prevention plate 8 is attached to the water flow pipe 5 so that snow other than the vicinity of the hole 6 and snow far from the hole 6 can be melted.

  This diffusion prevention plate 8 is attached so as to sandwich the upper and lower sides of the water flow pipe 5, and prevents the water vapor ejected from the hole 6 from diffusing in the vertical direction, thereby diffusing the water vapor in the horizontal direction accordingly. And ejected from the gap at the tip. When this diffusion prevention plate 8 is attached to the water flow pipe 5, a concave portion 81 is provided in the center of the plate-like member, and the water flow pipe 5 is welded thereto, and the plate-shaped umbrella portions 82 are positioned on the left and right sides of the water flow pipe 5. I will let you. If the tip 83 of the umbrella part 82 is extremely larger than the diameter of the flowing water pipe 5, the water vapor ejected from the hole 6 cannot be diffused in the lateral direction. The gap width is set so that water vapor can be ejected. If it does in this way, about the water vapor diffused up and down and right and left from the hole 6, the upper and lower diffusion prevention plates 8 can prevent the vertical diffusion, and the water vapor can be ejected in the left and right direction, and the lower layer portion of the snow is made flat Can be melted. At this time, if the diffusion prevention plate 8 is made of a metal having high thermal conductivity, the diffusion prevention plate 8 can be heated, and the snow accumulated thereon can be melted. In addition, since the diffusion prevention plate 8 is provided in the vertical direction along the inclination direction, the snow in that portion can be slid from the diffusion prevention plate 8 and dropped.

  Moreover, about this water flow pipe 5, you may make it attach not only in the up-down direction of the roof 9, but in the left-right direction along the uppermost part of the roof 9, as shown in FIG. Similarly, when attaching to the uppermost part, the hole 6 is provided toward the lower side of the roof 9 and the diffusion preventing plate 8 is provided so as to sandwich the upper and lower sides of the water pipe 5. In this embodiment and the like as well, components having the same reference numerals as those in FIG. 1 and the like have the same configuration, and a diffusion prevention plate 8 is also attached to the water pipe 5 provided at the uppermost portion of the roof 9. Shall.

  If it does in this way, while being able to melt the snow along the inclination direction of the roof 9 with the flowing water pipe 5 attached to the inclination direction, it pushes snow downward with the flowing water pipe 5 provided in the left-right direction of the uppermost part. Can do. In this case, particularly in the region surrounded by the right and left water pipes 5 and the uppermost water pipe 5 provided in the inclined direction, the snow can be melted from above and in the left and right directions, so that the snow can be more easily dropped. be able to.

  In addition, when water vapor is ejected from the side surface of the water pipe 5 in this way, the snow can be melted at the lowermost part of the snow, but the snow accumulated on the upper layer side cannot be melted, Therefore, there is a possibility that snow cannot be dropped due to the frozen part. Therefore, as shown in FIGS. 6 and 7, a hole 6 is also provided in the upper surface portion of the water pipe 5 provided along the inclination direction, and water vapor or the like is directed upward (from the direction of snow lamination) therefrom. Can be made to erupt. In this way, the snow can be cut not only by the lowermost layer of the snow but also by the water vapor spouted upward, making it easier to drop the snow. Even in this case, if the diffusion prevention plate 8 is provided so as to sandwich the hole 6 provided in the upper part, the snow can be cut more linearly. Similarly, in the case where the hole 6 is formed in the upper part of the water pipe 5, the diffusion prevention plate 8 is attached so as to sandwich the hole 6 so that the water vapor is ejected in a planar shape. To do.

  Thus, according to the above embodiment, in the snow melting apparatus 1 for melting snow accumulated on the roof 9 having an inclined surface, the water pipe having the hole 6 that is disposed on the roof 9 and ejects hot water or water vapor. 5 and a plate-like diffusion prevention plate 8 for preventing the vertical diffusion of hot water or water vapor ejected from the hole 6 of the water flow pipe 5 are provided. The diffusion of the water vapor in the vertical direction can be prevented, and the snow can be melted entirely by ejecting hot water or water vapor in a flat shape from the tip of the diffusion preventing plate 8. Also, the snow piled on the diffusion prevention plate 8 can be melted by the heat of the diffusion prevention plate 8 and dropped.

  Further, since the diffusion prevention plates 8 are provided above and below so as to sandwich the flowing water pipe 5, even when hot water or water vapor is ejected to the undulated portion such as the roof tile 91, it is provided so as to be sandwiched up and down. By the diffusion preventing plate 8 thus formed, hot water and water vapor can be ejected uniformly from the tip portion of the diffusion preventing plate 8.

  Furthermore, since the water flow pipe 5 is arranged along the inclination direction of the roof 9, the snow accumulated in the vicinity of the diffusion prevention plate 8 can be melted in all directions, and the snow falls from that part first. To be able to. In addition, along with the fall, the adjacent snow can be taken along and the snow in other parts can be dropped at the same time, so that more snow can be dropped.

  In addition, if the flowing water pipes 5 are provided in the inclination direction of the roof 9 and the uppermost part of the roof 9 and hot water or water vapor is ejected along the horizontal direction and the inclination direction of the roof 9, A part of the accumulated snow can be melted in the vertical direction, and the melted snow can be swept downward by hot water or water vapor ejected from above.

  In addition, this invention is not limited to the said embodiment, It can implement in a various aspect.

  For example, in the above embodiment, water is heated to be jetted as hot water or water vapor, but any water containing water may be used, for example, as a freezing point depressant, For example, calcium chloride or the like may be included. Moreover, in the said embodiment, although water vapor was ejected, you may make it eject hot water.

  Moreover, in the said embodiment, although the plate shape which pinches | interposes the upper and lower sides of the water flow pipe 5 was used as the diffusion prevention board 8, it provided so that it might protrude from the upper and lower sides of the hole 6 of the water flow pipe 5. You may do it.

  Furthermore, in the said embodiment, although hot water and water vapor | steam were ejected from the flowing water pipe 5, when the ejection is stopped for a fixed time or more, the water inside may freeze and block the hole 6 etc. There is sex. For this reason, a heater may be wound around the flowing water pipe 5, and the heater may be heated for a certain time before the ejection.

  In the above embodiment, the upper and lower diffusion prevention plates 8 are provided, but only the upper diffusion prevention plate 8 may be provided.
