Description

  The present invention relates to a snow cover water discharge pipe that discharges water on a roof to prevent snow cover, and a snow cover prevention apparatus using the same.

  The inventor of this application was born and raised in Snow Country (Aizu, Fukushima Prefecture). In the past, there was more than 1 meter of snow every year, and the snow that fell from the roof reached the height of the eaves. Each time, a snow staircase was built to enter and exit the entrance. In recent years, even though it is warming, the current situation is that heavy labor is always imposed on snow and snow on the roof. It was not until this year that I made a vague idea that there was something like a few years ago and made a model etc., and this was the Niigata Chuetsu Earthquake last year. As reported in the reports of heavy snowfall that came after the earthquake disaster, there are many areas in Japan, such as Yamakoshi Village, which suffer from snow accumulation. In so-called snowy countries, especially in rural areas or depopulated areas, all young people go out to the city and only elderly or elderly people have taken over their generations. During the snowfall, it was reported that the snow fell from the roof while it was snowing, broke or injured, and sadly died. This case was devised to eliminate such a matter as much as possible.

By the way, as a conventional technique, for example, there is a “snow removal apparatus” described in Patent Document 1 below. In this method, hot water or well water is jetted from a porous rotating pipe attached to the back of the roof.

  However, the above-described background art rotates a pipe for injecting water, and the structure is complicated and expensive.

  This invention pays attention to this point, and it aims at providing the snow cover prevention apparatus which can prevent snow cover effectively with respect to the whole roof, although it is a simple structure.

  In order to achieve the object, the first invention is a drainage pipe for preventing snow accumulation provided along a roof ridge and provided with a water discharge hole for discharging water on the roof, wherein the water discharge hole is provided. Is formed so as to discharge water substantially upward. According to a second aspect of the present invention, there is provided a snow cover prevention apparatus that uses the water cover for preventing snow cover, comprising a water supply device that supplies water or hot water to the water discharge pipe. One of the main forms is characterized by comprising a water collection mechanism for collecting water or hot water discharged from the water discharge pipe, supplying the water to the water supply device, and reusing it. The above and other objects, features and advantages of the present invention will become apparent from the following detailed description and the accompanying drawings.

  According to the present invention, snow or hot water for preventing snow accumulation is discharged from the water discharge pipe substantially upward, so that it is possible to prevent snow accumulation well on the entire roof.

  Hereinafter, the best mode for carrying out the present invention will be described in detail based on examples.

In this embodiment, the present invention is applied to a gable roof. The plan view of the roof is shown in FIG. In these drawings, drain pipes 14 and 16 are installed in a ridge (top or ridge) 12 of a roof 10. These water discharge pipes 14 and 16 are respectively connected to a water discharge distributor 18 installed near the center of the ridge 12 of the roof 10. The water discharge distributor 18 is constituted by a substantially T-shaped branch pipe, and the water discharge pipes 14 and 16 and the water supply pipe 20 are connected to each other. The water supply pipe 20 is connected to a water supply device 22 by piping.

  On the other hand, the eaves 24 of the roof 10 are provided with rain gutters 26, 28, and water collecting gutters 30, 32, 34, 36 are provided at both ends of the gutters 26, 28, respectively (see FIG. 2). ). These drainage basins 30 to 36 are connected to the drainage basins 46 and 48 through circulation pipes 38, 40, 42 and 44, and the drainage basins 46 and 48 are further connected to the circulation pipes 50 and 52. And is connected to the water supply device 22 through a pipe.

  FIG. 3 (A) shows an example of the water supply device 22. In the figure, the above-described circulation pipes 50 and 52 are connected to a water storage tank 56 through a mud reservoir 54. The water storage tank 56 is provided with a ball tap 58 and a drain 60 for draining water. The ball tap 58 is for adjusting the water level in the tank to be constant. When the water level is lowered, the water is supplied through the water meter 62 and the replenishment water supply pipe 64. . The water discharge side of the water storage tank 56 is connected to a pressurizing pump 68 via a supply pipe 66, and the water output side of the pressurizing pump 68 is connected to the water discharge distributor 18 via the water supply pipe 20 described above.

As shown in the figure, the water discharge pipes 14 and 16 are alternately formed with water discharge holes 15 and 17 facing upward. In the drawing, the outermost building is indicated by a center line LC, and water discharge holes 15 and 17 are formed at positions slightly deviated from the center line LC. The water discharge pipes 14 and 16 are formed of, for example, a resin pipe having an inner diameter of 13 mm. The diameter of the water discharge holes 15 and 17 is set to 2.5 to 3.0 mm, for example, and the interval between the holes 15 and 17 is set to 200 mm, for example. The Of course, you may change suitably according to the amount of snowfall.

  Next, the operation of the first embodiment will be described with reference to FIG. When snowfall is expected, the pressure pump 68 is driven in advance. Then, after the water in the water storage tank 56 is pressurized by the pressurizing pump 68, it is supplied to the water discharge pipes 14 and 16 through the water supply pipe 20 and the water discharge distributor 18. As described above, the water discharge pipes 14 and 16 are provided with the water discharge holes 15 and 17 facing upward. For this reason, as shown to FIG. 5 (A), water discharge is performed toward upper direction. The water falls on the roof 10 and flows on the roof to reach the gutters 26 and 28.

  Here, as shown in FIG. 5B, if water discharge holes 902 and 904 are provided on the side surface of the water discharge pipe 900, the water passes over the vicinity of the roof 10 and falls onto the roof 10. For this reason, snow 906, 908 comes to accumulate in the vicinity of the ridge of the roof 10, and cannot prevent snow accumulation well. However, according to the present embodiment, since water falls as shown in FIG. 5 (A), there is no inconvenience as shown in FIG. 5 (B), and snow is prevented well on the entire roof. Moreover, even if it compares with the prior art which rotates the pipe mentioned above and injects warm water and well water, the same effect can be acquired, without rotating a pipe.

  The water flowing on the roof 10 flows into the rain gutters 26 and 28 and further collected in the water collecting gutters 30 to 36. The water collected in the water collection tanks 30 to 36 is collected in the next water collection tanks 46 and 48 through the circulation pipes 38 to 44, and further sent to the mud reservoir 54 through the circulation pipes 50 and 52. In the mud reservoir 54, the inflowing water is temporarily stored. Thereby, the mud contained in water settles and is removed. The water from which the mud has been removed is sent to the water storage tank 56 where it is stored and reused again.

  In particular, in a cold region, it is preferable to use a water heater combined type water supply device 122 as shown in FIG. As shown in the figure, the water discharge side of the pressurizing pump 68 of the water supply device 122 is connected to the water heater 180 by a supply pipe 179. The water heater 180 is replenished with water through a water meter 62 and a replenishing water supply pipe 164. The hot water discharge side of the water heater 180 is connected to the water discharge distributor 18 through the water supply pipe 20. According to the water supply device 122 having such a configuration, the water stored in the water storage tank 56 is pressurized by the pressurizing pump 68 and then supplied as hot water by the water heater 180 to the discharge pipes 14 and 16. . On the other hand, the tap water supplied from the replenishment water supply pipe 164 is also heated to the water discharge pipes 14 and 16 by the hot water heater 180. Note that this is a direct water supply method to compensate for the insufficient water in the water storage tank 56, but the water in the water storage tank 56 and tap water are used alternately. May be.

  As described above, according to this embodiment, water or warm water falls from the roof ridge and flows on the roof, so that it is possible to obtain a good snow prevention effect on the entire roof while having a simple structure. it can. Furthermore, when the water discharge pipes 14 and 16 and the water distribution / distribution device 18 are worn out or damaged, it is economical because only the relevant part needs to be replaced and the entire part need not be replaced.
