Description

  The present invention relates to a snow fence that is installed on the side of a road or on the side of a track in order to reduce the amount of snow on the road or the track in winter and to reduce visibility.

  The conventional snow fence is designed to exhibit the maximum effect when wind and snow blows perpendicularly to the snow fence. However, although the snow fence is installed on the windward side of the road where the seasonal wind blows, the road is not always constructed in a direction perpendicular to the wind direction of the seasonal wind. Therefore, the effect is low when wind and snow blows obliquely against the snow fence.

  Therefore, there is known a windbreak plate or the like provided on a snow fence to change the wind direction in a direction perpendicular to the road.

  For example, as shown in Japanese Utility Model Registration No. 3097796, the height of the snow fence is constant at the same height as the height of the snow fence in a certain angular direction including a right angle with respect to the direction in which the snow fence is arranged on the rear side of the snow fence. There is a known thing in which a wind-tuning plate with a width is vertically attached at intervals. According to this device, even if wind and snow blow obliquely to the snow fence, the wind control plate prevents components parallel to the snow fence, so that the effect of the snow fence can be maintained.

  Further, as shown in Utility Model Registration No. 3103653, a plurality of wing-shaped air passage deflecting plates and a support column are provided, and a flow of wind blown from an oblique lateral direction with respect to the air passage deflecting plates is The thing which has the baffle plate which rectifies | straightens toward to at least one of the upper surface or lower surface of an air-path deflecting plate is known. According to this device, it is said that wind and snow (wind and snowstorm) blowing from an oblique lateral direction can be effectively deflected toward the road.

Utility model registration No. 3097796 Utility Model Registration No. 3103653

  In the above-mentioned utility model registration No. 3103653, there is shown a blown-off type object that forms a wall of a snow-proof plate and keeps snow in its shadow without passing wind. In the blowing type, the height of the fence is determined so that the snow accumulated in front of the snow fence does not cross the fence, and there are few problems even if wind snow is deposited obliquely against the snow fence.

  In addition, in the same idea, the snow-breaking fences that blow off the snow by blowing wind on the road surface by installing multiple layers of snow-proofing plates with an angle with respect to the horizontal direction are exactly the same. It is said that the performance of the snow fence can be improved by attaching wind-conditioning plates perpendicular to the snow fence at regular intervals.

  However, in the case of wind blow type, when wind and snow are blown obliquely in a direction that is relatively perpendicular to the snow fence, it can pass through the snow board smoothly, but obliquely from an acute angle of 45 degrees or less from the direction in which the snow fences are lined up. In the case of spraying on the windshield, snow may accumulate on the air conditioning plate before it loses its function.

  Although the above-mentioned utility model registration No. 3103653 is a blow-off type, the current plate is attached to a snow plate (wind path deflection plate), and the current plate is determined from the strength of the snow plate. When it is blown obliquely from an acute angle with respect to the snow fence, it cannot be effectively deflected toward the road.

  Moreover, in the above-mentioned utility model registration No. 3103653, it is shown that the angle of the wind regulation plate can be changed to a constant angle direction, but when the road is bent or at the mountainside If the wind direction is not constant, the angle of blowing against the snow fence will differ depending on the installation location, and the angle of the wind regulation plate cannot be handled in the constant angle direction.

  Further, the wind regulation plate as shown in the above-mentioned utility model registration No. 3103653 has a wind regulation plate of a certain width attached and protruded on the back side which hits the windward side of the snow fence, but the back side of the snow fence becomes agricultural land. In many cases, this may hinder the work during summer farming.

  Therefore, the present invention can change the wind direction in a direction orthogonal to the road even when sprayed obliquely from an acute angle to the snow fence, and in the direction orthogonal to the road even when the wind direction is not constant along the road. The purpose of the present invention is to provide a blow-off type snow fence with a slant wind guide plate that can change the wind direction and does not protrude to the windward side of the snow fence in the summer.

  The blow-off type snow fence with a slant wind guide plate according to claim 1 is a slant wind guide having a constant width in a certain direction with respect to the direction in which the snow fences 10 and 20 are arranged on the rear side of the snow fences 10 and 20 on the windward side 2.
