Abstract

PROBLEM TO BE SOLVED: To provide a snow-removing device which is operated to efficiently remove the snow on a beam when the snowfall is on the predetermined level. SOLUTION: An electric-driven fan 1 is fitted on the beam B with an air blowing direction toward the extending direction of the beam B. A snowfall sensor for detecting the snowfall per unit time and a temperature sensor 3 for detecting the outside temperature are fitted in the vicinity of the beam B. Detection signals from the snowfall sensor 2 and the temperature sensor 3 are received by a control device 4, and if the snowfall over the preset value and the outside temperature below the preset value are detected, the fan 1 is operated, and the snow on the beam B is blown and removed by the air.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow removing device for preventing snow on a beam erected so as to cross over a railway line in order to support a train line.

[0002]

2. Description of the Related Art When snow accumulated on a beam of a railway line falls onto a train passing below, there is a risk that driving will be hindered. 2. Description of the Related Art Conventionally, as a measure for removing snow accumulated on a beam, a paint that hardly adheres to snow is applied, or a roof-like inclined plate, on which snow easily slides, is provided.

[0003]

The above-mentioned conventional snow removal measures by painting are susceptible to the beam shape, snow quality, temperature and the like, so that a sufficient effect cannot be expected. The sloping plate may cause snow accumulated on the sloping plate to fall at a time, and still affect the running of the train. Accordingly, it is an object of the present invention to provide a snow removing device that operates when a predetermined amount of snow falls and efficiently removes snow on a beam.

[0004]

According to the present invention, in order to solve the above-mentioned problems, an electric fan 1 arranged on a beam B with a blowing direction directed to an extension direction of the beam B,
A snowfall sensor 2 for detecting the amount of snowfall per unit time;
A temperature sensor 3 for detecting an outside air temperature, a control device 4 for receiving a detection signal from the snowfall amount sensor 2 and the temperature sensor 3 and operating the fan 1 when detecting a snowfall amount equal to or more than a set value and an outside air temperature equal to or less than the set value. And a snow removing device for a railroad track beam is configured to blow off and remove snow accumulated on the beam B by the wind power of the fan 1.

[0005]

Embodiments of the present invention will be described with reference to the drawings. 1 is a front view of the snow removing device, FIG. 2 is a side view of the snow removing device, and FIG. 3 is an explanatory diagram of the snow removing device.

In FIGS. 1 and 2, a beam B horizontally traversing over a railway line is supported by a column P. Mounted on the beam B is an electric fan 1 having a capacity to generate a wind force sufficient to blow off the snow on the beam. One or more fans 1 are arranged with the air blowing direction directed to the extension direction of the beam B according to the length of the beam B. When mounting a plurality of fans, it is convenient not to make adjacent fans face each other. Note that the fan 1 can be swung as necessary.

[0007] A snowfall sensor 2, a temperature sensor 3, and a control device 4 are mounted on the pillar P. As shown in FIG. 3, the snowfall sensor 2 optically detects the snowfall per unit time (the number of raindrops) and sends a detection signal to the control device 4. The temperature sensor 3 detects the temperature of the outside air and sends a detection signal to the control device 4. The control device 4 receives the detection signals from the snowfall amount sensor 2 and the temperature sensor 3 and receives a snowfall amount equal to or more than a set value and an outside air temperature equal to or less than the set value, for example, a snowfall count of 60/2 min. Is detected, the fan 1 is operated. 5 is a temperature controller. The fan 1 starts and stops repeatedly according to snowfall.

Accordingly, the snow removing device starts and stops the fan 1 at appropriate times, blows off the snow falling on the beam B, and prevents snow accumulation.

[0009]

As described above, according to the present invention, the electric fan 1 disposed on the beam B with the air blowing direction directed in the extension direction of the beam B, and the snowfall detecting the amount of snowfall per unit time The fan 1 operates when it receives the detection signals from the quantity sensor 2, the temperature sensor 3 for detecting the outside air temperature, the snowfall amount sensor 2 and the temperature sensor 3, and detects the amount of snowfall above the set value and the outside air temperature below the set value. And a control device 4 for removing the snow accumulated on the beam B by the wind force of the fan 1 so as to blow off and remove the snow accumulated on the beam B; And the safety of train operation can be ensured.
