Abstract

PURPOSE:To safely and quickly remove snow without damaging the surface of a road, by mounting a snow-removing blade, a microwave generator, shields against microwaves, a vertical shaft type rotary brush and an exhaust pipe on a car. CONSTITUTION:While a car body 1 is being moved, snow on a road is removed by a snow-removing blade 14, and microwaves (2450MHz) from a microwave generator 2 are irradiated on the surface of the road through a wave guide 3 and are screened by shields 4, 5, 17. A vertical shaft type rotary brush 8 for cleaning is driven by a brush-driving motor 7 and the road surface covered with microwave-melted ice or snow is cleaned. Furthermore, a high-temperature gas exhausted from an internal combustion engine for traveling the car body 1 and for driving a generator is sprayed on the road surface through an exhaust port 13 and the road surface is allowed to dry.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave type snow removing work vehicle for removing ice and snow on a road surface or a rail.

[0002]

2. Description of the Related Art For snowy roads, frozen roads, etc., as shown in the side view and the plan view of FIG. 4, conventionally, ice and snow on the surface are removed by a Russell car, and chains or studless tires are mounted on the surface. The vehicle is running. In addition, snow removal work is also carried out by spraying snow remover.

[0003]

However, in the snow removal work by the Russell vehicle, there is a risk of slippage when the vehicle is traveling, because an ice layer remains on the road surface. Further, in this type of snow removal work vehicle, since snow is mechanically removed, the road surface is often damaged by the snow removal blade, and thus it is necessary to repair the road after spring. Further, when the road surface condition cannot be seen due to snow or the like, the snow removing vehicle may hit the curb and damage the road surface curb. Further, in the snow removing work using the snow removing agent, since the snow removing agent contains chlorine, there is a problem that the vehicle and surrounding metal are rusted.

The present invention has been proposed in view of the above circumstances, and it is possible to remove snow and icing on a road surface or rail safely, promptly, and save labor and labor without damaging the road surface or rail. It is an object of the present invention to provide a high-performance and economical microwave-powered snow removal work vehicle.

[0005]

To this end, the invention of claim 1 is a snow removing work vehicle traveling on a road surface, which is provided so as to project from a lower portion of the front end of the vehicle body, and the lower end reaches the height close to the road surface over the entire width. A blade for snow removal, a microwave generator of 2450 MHz and a cooling device mounted in the central part of the vehicle body, a power generator and a fuel tank mounted in the central part or the rear part of the vehicle body, and an opening on the lower surface of the vehicle body A waveguide that radiates microwaves oscillated from the microwave generator toward the road surface, and a waveguide that is hung on the lower surface of the vehicle body and surrounds the lower end opening of the waveguide over the entire width of the vehicle body, and the lower end is the road surface. A horizontal rectangular weir frame-shaped microwave shield that reaches nearby, a vertical rotary brush that hangs on the underside of the vehicle body to wipe off ice and snow on the road surface, and the exhaust that is projected below the generator and blows its exhaust to the road surface. Characterized in that comprising an exhaust pipe attached.

According to the invention of claim 2, a microwave generator of 2450 MHz mounted on a vehicle body traveling along a rail and a cooling device for the microwave generator, and an upper microwave opening to a lower surface of a front portion to a central portion of the vehicle body. A waveguide that radiates microwaves oscillated from the generator toward the road surface, and a horizontal pipe that is hung on the lower surface of the vehicle body and surrounds the lower end opening of the waveguide over the entire width of the vehicle body, and the lower end reaches near the rail. It is equipped with a rectangular weir frame-shaped microwave shield and a vertical axis rotating brush that wipes off ice and snow on the same rail that is hung on the lower surface of the vehicle body, and receives power from an overhead wire via a pantograph to run, The microwave generator and the cooling device thereof are operated and the rotary brush is driven.

According to a third aspect of the present invention, in the second aspect, the vehicle is provided with a power generator and a fuel tank, instead of the overhead line and the pantograph, and the vehicle is driven by the electric power generated by the power generator, and at 2450 MHz thereof. The microwave generator and the cooling device thereof are operated and the rotating brush thereof is driven.

[0008]

According to such a configuration, the following operation is performed. (1) The microwave generated by the microwave generator passes through the waveguide and irradiates the road surface from the lower end opening. (2) At that time, the microwave is absorbed by the water (ice, snow) on the road surface, and the temperature of the ice and snow is increased and the snow is melted. Since water has a higher microwave absorption coefficient than objects such as roads and shields, microwaves are absorbed not by the shields or roads but by the water on the road surface. (3) By removing the melted ice and snow with a brush, the road surface is cleaned and snow removal is completed. (4) The power required for microwave generation and brush drive is
It is supplied from a power generator installed on board or externally by a supply mechanism (pantograph etc.) or a storage battery. (5) If the control panel, the auxiliary equipment, the fuel tank, the auxiliary equipment, etc. necessary for the operation of the microwave generator, the power generator, etc. are all mounted on the vehicle, the vehicle can be operated anywhere. (6) When there is a large amount of snow, a snow blade is attached to the front of the vehicle to push away the snow, and then the ice on the road surface is removed. (7) In the case of a power generator using an internal combustion engine, high-temperature (several hundreds of degrees Celsius) exhaust gas is blown onto the road surface to melt ice and snow on the road surface.

(2) Applying heated metal to melt ice and snow,
Compared with the method of spraying a flame, by using the microwave of 2450MHz, it becomes possible to heat rapidly from the inside of the ice and snow regardless of the uneven shape of the ice and snow, the power density is high, and the heating control is electric. Since it is controlled by, it is easy and the entire road surface can be heated uniformly. At this time, snow melting and ice melting caused by blowing a flame under the vehicle pose a safety problem for the vehicle, but in the present invention, microwaves are used and the microwaves are reflected by the metal, so there is no danger. (3) The microwave uses a frequency of about 2450 MHz for industrial use. Microwaves in this wavelength range have a high absorption rate for water, so they are preferentially absorbed by ice and snow, especially water that begins to melt on the surface.
