Description

Detailed Description of the Invention "Industrial Application Field" The present invention is a method for removing snow accumulated on rooftops in areas with heavy snowfall by manually dropping it onto both sides of highways or onto snow removal trucks. This invention relates to a rooftop snow removal device that melts the snow moment by moment immediately after it falls and can automatically remove it in the form of running water without the work requiring a huge amount of labor or the dangers associated with this work.

``Prior art'' In areas with heavy snowfall, if snow falls continuously, it may accumulate on the roofs of buildings and the buildings may not be able to withstand the weight of the snow and may collapse. As time passes, people climb onto the roof and manually remove the snow.

``Problems to be solved by the invention'' It takes a tremendous amount of effort for a person to climb onto the roof and remove snow manually, and in households where there are only women, children, and elderly people who do not have the labor to remove snow themselves, Separately, workers have to pay wages for snow removal, which costs a huge amount of money.Also, workers do not have time to remove snow during the day, so they have to climb high rooftops to remove snow after returning home at night, which is extremely dangerous. It is truly a huge problem in people's lives, with more and more people becoming victims every year.
Moreover, there is no countermeasure against this, and the situation is hopeless.

An object of the present invention is to provide a rooftop snow removal device that can remove the heavy pressure exerted on buildings and the like by snowfall in heavy snowfall areas without requiring any human effort.

``Means for solving the problem'' A hollow body made of a thermally conductive material on the top surface and a non-thermal conductive material or heat insulating material coating on the circumferential side and bottom surface is placed on the rooftop of a building, and the hollow body is A heated fluid injection port is provided at the bottom of the hollow body, and a heated fluid outlet is provided at the top of the hollow body, and heated fluid is supplied from the heated fluid injection port into the hollow body to prevent snow falling onto the top surface of the hollow body from accumulating. The system allows the snow to melt immediately after it falls, allowing it to flow automatically as it falls.

"Embodiments and Effects" The attached drawings show embodiments of the apparatus used in the present invention.
Fig. 1 shows a heating fluid exclusively used for liquids, Fig. 2 shows a heating fluid that can be used for both gas and liquid, and Fig. 3 shows a heating fluid that uses groundwater.

1 is a hollow body, the top plate 2 is made of a known metal plate or plastic plate with heat conductivity and durability, and the four side plates 3 and the bottom plate 4 are made of materials with relatively poor heat conductivity such as wood. It consists of a hexahedron 6 made of material or any durable material with a thermally non-conductive coating. In principle, the hexahedron 6 is hollow and sealed, and when gas is used as the heating fluid, an air vent 5 is opened at the top of the hollow body.
Reference numeral 6 denotes a heating fluid injection port, which is connected to a device (not shown) for heating a fluid such as water by using residual heat from an indoor heating device and turning it into a heated fluid via an inflow pipe 7 or the like. Reference numeral 9 designates a heated fluid outlet opening at the top of the hollow body 1 such as a rooftop ridge. Reference numeral 10 denotes an outflow pipe that connects the outflow port 9 and the heating fluid converting device.

The present invention has the above configuration, and when it snows, heating fluid heated by an indoor heating device or the like is injected into the hollow body 1 from the heating fluid injection port 6 through the inflow pipe 7. In this case, a pump 11 may be interposed in the inflow pipe 7 as necessary. In this way, the hollow body 1 is filled with heating fluid, and the top plate 2 made of a heat conductive material on the top surface of the hollow body 1 is heated. The snow particles falling onto the heated top plate 2 melt when they come into contact with the top plate 2,
It automatically flows down to the sewer system, etc., and does not give the fallen snow a chance to accumulate on the roof, and automatically performs the snow removal function.

As described above, the present invention does not require any human effort and is not dangerous, and there is no risk of requiring some extra heat for room heating in order to carry out the present invention. However, the extra consumption of heating costs is extremely small compared to the cost of human labor. Furthermore, when using groundwater, as shown in Fig. 3, the bottom plate 4 of the hollow body 1 made of styrofoam or the like is brought into contact with the roof 12 without any gaps, and the inflow pipe 7 is drilled underground. The well 13 is extended into the groundwater layer 14 and opened, and a pump 11 is interposed between the pipes 7 and the groundwater is suctioned and injected into the hollow body 1. On the other hand, the outflow pipe 10 opens its tip into the groundwater aquifer 14 in a separate well 15, returns used groundwater underground, prevents the possibility of ground subsidence caused by pumping up groundwater, and solves social problems. Care should be taken not to cause this. In addition, if the calorific value of groundwater alone is insufficient,
It may also be used in combination with the heating device that utilizes the residual heat.

"Effects of the Invention" According to the present invention, as mentioned above, residual heat from indoor heating is used to melt and flow snow immediately after it falls, and a small amount of heating is consumed. However, it has been able to solve the unique problem of snow removal that requires manual labor, which is unique to areas with heavy snowfall, and it has also been able to eliminate the extremely dangerous snow removal work that requires manual labor, and is highly effective. .
