Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow melting apparatus capable of effectively and efficiently melting snow from which snow has been removed.

[0002]

2. Description of the Related Art In northern countries, the amount of snowfall is large, and if the snow that has accumulated on city streets and roads is left as it is, the traffic function and the like will be paralyzed. For this reason, snow is removed with a large rotary snowplow, and the snow is generally dumped on a large dump truck or the like to rivers flowing in the suburbs.

[0003] However, since such work is usually performed at night, noise problems such as large dump trucks, harmful substances in dumped snow flow out into rivers together with snow melting to cause environmental problems, and dumping places are limited. And
There were various problems such as deterioration of working conditions due to long-distance transportation and the like.

In view of the above problems, the present inventor has disclosed in Japanese Patent Application Laid-Open No. Hei 6-240636 a water reservoir 52 having a drain 51 as shown in FIG. A plurality of heat transfer tubes 53 are connected to each other, and a heating tube 55 provided with a combustion device 54 is provided at an end of the heat transfer tube 53, and snow removed from the city or the like is scattered onto the water storage portion 52 by appropriate means. As a result, the fallen snow is melted by the heat of the heating pipe 55, and
2 discloses a snow melting apparatus 50 configured to melt snow falling in the water storage section 52 with water.

[0005]

However, when the snow melting device 50 is actually operated, a large amount of snow falls, for example, while the combustion device 54 is not operating. Then, a new problem has emerged in that much time and fuel must be devoted to melting the snow, and it takes a long time to restart operation.

The present invention is an improvement of the snow melting apparatus 50 in view of the above problem. Even if a large amount of snow is stacked on a heating tube, the snow melting apparatus 50 can efficiently melt snow in terms of time and fuel consumption. It is an object of the present invention to provide a snow melting apparatus capable of more efficiently melting a large amount of snow.

[0007]

According to a first aspect of the present invention, there is provided a snow melting apparatus having a water reservoir having a drain port.
In the water storage section, heating pipes connected at appropriate density are arranged in parallel over substantially the entire surface of the water storage section, and a combustion device is connected to at least one end of the heating pipe so that combustion gas is injected into the heating pipe. Along with at least one of the other ends as an exhaust port, and once around the one end of the heat generating tube, from the vicinity of the end along the upper side of the heat generating tube in at least one direction, upward at appropriate intervals A water guide pipe provided with the fountain mechanism described above, and a shower mechanism provided on at least one side of the water storage section.

Further, the snow melting apparatus of the present invention can perform a more excellent snow melting process by adding the following configuration.

With respect to the heat pipe, if the heat pipe is disposed at substantially the same height as the drain port, heat can be transmitted to the water in the water storage section most efficiently. In addition, by using a multiple tube in which one or more inner tubes are inserted into one outer tube, the temperature of the gas flowing through the heating tube is less likely to decrease, so that heat can be sufficiently transmitted to the end of the heating tube. Will be able to supply.

With respect to the water pipe, the water enters the outer pipe near the one end of the heat pipe from the water supply source, and is made to circulate along the inner peripheral surface of the outer pipe for an appropriate length. By arranging, the heated water can be spouted from the fountain mechanism, and the snow melting ability of the snow melting device can be further enhanced. Also, if the fountain mechanism of the water pipe is provided so as to fountain upward and obliquely upward on both sides of the pipe, snow accumulated on the heating pipe can be cut into blocks by the oblique fountain from the adjacent water pipe. Therefore, even if a large amount of snow is stacked on the heating tube, the snow melting process can be efficiently performed.

Further, if a peripheral water pipe is arranged along the peripheral wall surface of the water storage section at a position lower than the drain port and the peripheral water pipe and the water pipe are connected, the peripheral water pipe is connected through the water pipe. Since the heated water can be circulated to the outside and the water near the peripheral wall surface of the water storage section can be heated, the snow melting efficiency of the snow melting apparatus can be further improved.

Regarding the shower mechanism, it is preferable that a submersible pump is installed near the combustion device in the water storage section so that the water heated by the combustion device in the water storage section is fountain from the shower mechanism.

In addition, by disposing the rotary discharge mechanism near the drain in the water storage section, even if the snowmelt water in the water storage section is in a sherbet state, it can be forcibly sent to the drain and drained.

[0014]

When the snow is supplied to the water storage section by appropriate means such as scattering or throwing snow, the snow falling on the heat pipe is melted by the heat of the heat pipe and the fountain by the water pipe, and further by the fountain by the shower mechanism. The snowmelt is stored in the water reservoir. On the other hand, snow that has fallen directly into the water storage portion is efficiently melted by the water in the water storage portion, particularly, the water heated by the heating pipe and the surrounding water pipe.

A part of the snow-melting water thus melted and stored in the water storage part is sucked up by the submersible pump installed near the combustion device, and is again fountained into the water storage part from the shower mechanism, and partly drained from the drain port. It is supposed to be.
