Abstract

PURPOSE:To easily ensure a snow melted surface by combining a hard board having a heat insulating material stuck onto the lower surface and double heat passages reversed in the circulating direction of a heat medium formed therein as a unit, and removably and attachably constituting a snow melting panel. CONSTITUTION:A hard board 101 has a heat insulating material 101 stuck onto the lower surface and double heat passages 103, 104 reversed in the circulating direction of a heat medium formed therein, and a snow melting panel 100 is formed thereby. The panel 100 is connected to a heat source 200 such as a boiler through both pipeline systems 300 of a heat supply system 301 and a heat return system 302. In winter, the panels 100 are laid on a necessary part such as a garden with the heat insulating surface 102 down to form an entrance passage, and the heat source 200 is driven, and the heat medium is circulated so as to be supplied to one of the passages 103, 104 and returned from the other. Thus, the snow on the panel can be effectively melted.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a snow removal device that creates a road surface by laying an appropriate number of snow removal panels in order to secure an access road to a garden of a private residence or the like in winter.

[Conventional technology]

Conventionally, when removing snow that has accumulated on the road surface, -C,
Methods are used to heat these parts using electric heaters buried in them, or to run hot water over them.

[Problem to be solved by the invention]

However, the above-mentioned method using an electric heater consumes a lot of electricity, is bulky, and is uneconomical. In addition, the heater is buried in road concrete, etc., which requires large-scale equipment and cannot be easily removed. There were also problems. On the other hand, methods using hot water require a large amount of water;
In addition, it is necessary to heat this water appropriately, and the treatment of both supply water and snow melting water that is generated in large quantities becomes a problem, making it unsuitable for securing access roads to private residences etc. was there. The present invention has been made in view of such conventional circumstances.

[Means to solve the problem]

The characteristic feature of the present invention is that a heat insulating material is attached to the lower surface of a hard board, and two electric heating passages are formed in the hard board in which the circulation direction of the heat medium is opposite to each other.
A snow-blowing panel in which the hard boards are appropriately combined as a unit and removably laid in a snow-blowing area, a heat source supplying a heat medium to the snow-blowing panel, and a pipe connected between the heat source and the snow-blowing panel. The snow removal equipment is equipped with both a heat supply system and a heat return piping system.

[Effect]

Therefore, in the present invention, by laying an appropriate number of hard board snow removal panels in the garden of a private residence, for example, in winter, the snow on the snow removal panels is removed, and a snow removal road surface can be easily secured. Ru.

【Example】

FIGS. 1(A) to 1(C) show several embodiments of the snow removing device according to the present invention. In the case of FIG. 1(A), a plurality of snow removing panels 100 are laid in a vertically long line, and in FIG. 1(B), a plurality of snow removing panels 100 are bent vertically (hook shape). Figure 1 (C) shows the case in which five snow removal panels 1 were installed.
This is a case where 00 is laid relatively medium wide, and in both cases,
It is formed as an access road to the gardens of private residences during the winter. As shown in FIG. 2, this snow-blowing baffle 100 is made up of a hard board 101 such as a concrete board, and a heat insulating material 102 such as a foamed hard resin attached to the bottom surface of the hard board 101. These snow removal panels 100 and a heat source 200 such as a boiler are formed with double heat passages 103 and 104 in which the heating medium circulates in opposite directions.
means both piping systems 3 of the heat supply system 301 and the heat return system 302.
It is connected by 00. One specific example is as shown in FIG. 3, for example, protruding connection parts 103a and 104a are formed on the snow removal panel 100 side by slightly protruding a part of the dual heat passage 103104, and on the other hand, A T-shaped connecting pipe part 303 is attached to the piping system 300 side, and these two parts are butted together via a connecting part 304 such as a rubber pipe, and the outer periphery is tightened with a mounting fitting 305 or the like. On the other hand, the connections between the snow removal panels 100 are as shown in FIG.
A relay connection part 306 such as a rubber pipe is fitted into the protruding connection parts 103a and 104a of 104, and its outer periphery is tightened with a fitting 305 or the like. Therefore, in the case of the snow removal device of the present invention, a plurality of the snow removal panels 100 are installed with the insulation material 1 in a necessary place such as a garden in winter.
Lay it with the 02 side facing down, and first create the desired approach path. This installation can be done simply and easily using the parts 303, 304, 306 and the mounting fittings 306 in a removable manner. After completing the installation in this manner, the boiler of the heat source 200 may be driven. Then, hot water is supplied to the heat supply system 301
The return water is supplied to one of the dual heat passages 103, 104 of the snow removal panel 100 from the piping system 300 of the heat return system 302, and the return water is returned to the heat source 200 and circulated through the piping system 300 of the heat return system 302. Therefore, the snow on the snow removal panel 100 is effectively removed. Here, the hard board 101 of the snow removal panel 100 has a heat storage function, and the heat insulating material 102 prevents conduction of heat to the ground side, so that an extremely good snow removal effect can be obtained. Moreover, since the hard board 10I of this snow-blowing puddle 100 has sufficient strength, it can withstand not only the traffic of people but also the running of automobiles and the like. The fifth example shows still another embodiment of the snow removal device according to the present invention. This is a case where the heat source is a heat exchanger that uses geothermal heat, and as shown in FIG. It is formed from a processed copper pipe, and the copper pipe portion is buried underground, for example, at a depth of about 4 to 5 meters. In order to prevent each copper tube from moving, it is preferable to fix each steel tube with a holder plate 403. In the case of this heat exchanger 400, underground 4 to 5
The depth of about 1.5 m is always 11-12° even in winter.
Since the snow melting panel 100 is kept at a temperature of around 100°C, heat can be emitted from the 100 parts of the snow removal panel and the snow can be sufficiently extinguished. It is heated. In the case of this heat exchanger 400, unlike a boiler, it does not have a pump function itself, so a pump 500 is installed in a part of the piping system 300. The overall function is shown in Figures 1 (A) to (C) above.
).

【Effect of the invention】

As is clear from the above description, the snow removal device according to the present invention provides the following excellent effects. (1) Since the snow-blowing panels can be easily installed and removed, it is possible to easily secure a snow-blowing road surface of an appropriate shape, for example, as an access road into the garden of a private residence only during the winter. (2) The hard board of this snow removal panel has heat storage properties.
Also, when installing, the insulation part should be on the ground side.
It has good thermal efficiency and provides an extremely good snow-melting effect. (3) Furthermore, in the dual heat passages and piping systems of the snow removal panel, two systems in which the heating medium circulates in opposite directions are used, ensuring uniform heat generation in the heat generating area. (4) Furthermore, since only snow melting water is generated, there is little risk that the original function of the road surface will be impaired. (5) In the case of geothermal use, a significant reduction in energy consumption can be expected.
