Description

[Detailed Description of the Invention] The present invention relates to an improvement of the drainage ditch cover installed in snowy regions.

Conventionally, when removing accumulated snow, snow was shoveled, and the snowpack was crushed with a shovel or the like and then discharged into the side ditch.

As a result, ice freezes or snow accumulates on and around the gutter edge, making work difficult, adding the risk of slipping and causing injury, and requiring a lot of work to crush snow packs when shoveling snow. It required a lot of effort.

This invention is intended to solve the above-mentioned drawbacks. First, a lid for drifting snow gutter with a built-in snow breaking net is installed in the gutter, and the snow chunks are fed into the snow breaking net and crushed, thereby effectively discharging the snow into the gutter. It was designed to be released into the river.

An example of implementing the present invention will be explained with reference to the drawings.
As shown in FIG. 3, side plates 1a each having an L-shaped cross section are placed facing each other at both ends in the length direction (bearing bar direction a) of the frame 1, which is formed into a nearly rectangular shape in a plane. , side plates 1b each having a rectangular cross-section are placed and assembled at both ends in the width direction (one direction b of the twist bar) so as to face each other.

Next, an appropriate number of receiving pieces 2 are installed horizontally at required positions on the lower flange edge of the side plate 1a having an L-shaped cross section, and an appropriate number of receiving pieces 2 are installed horizontally at required positions on the lower part of the web of the side plate 1b having a rectangular cross-sectional shape. and the respective receiving pieces 2 are installed parallel to each other.

Subsequently, a side plate 3 having an inverted cross-sectional shape is welded and fixed to the flange upper surface and web of the side plate 1a having an L-shaped cross-section, and a reinforcing material 4 is welded and fixed to the inner edge of the side plate 3 to form a raised member 5. .

This raised member 5 is just one example, and may be formed using square pipes or section steel of various shapes as required.

Next, as shown in FIGS. 1 and 2, on the receiving pieces 2 installed in parallel at the lower part of the inside of the frame 1, a cross-shaped braid was formed into a substantially rectangular frame 6a as shown in FIG. A snow breaking net 7 formed by fixing the net 6b is placed and fixed on the four circumferential receiving pieces 2.

Although an example of a snow breaking net braided in a cross shape has been described, nets of various shapes can be formed depending on the size of the snowpack.

Subsequently, as shown in FIGS. 1 and 2, a grating 9 with pin holes 8 drilled at one end of the side plate is placed on the raised material 5 in the frame 1, and a rectangular shape is formed with the pin hole 8. Cross-sectional side plate 1b
Insert the pin 11 by aligning it with the pin hole 10 carved in the
A grating 9 can be opened and closed with respect to a frame 1.

Further, a retractable handle 12 is attached to a desired position of the bearing bar a of the grating 9.

To explain how to use the snow drifting groove lid constructed as above, when starting snow shoveling work, first pull out the grating handle 12, pull up the grating 9 upward and rotate it to create an inclination of approximately 110°. The door is opened to an angle and held by one end of the side plate 1a.

Next, during this time, if the snowpack is directly thrown into the frame 1 with the door open, the snow breaking net 7 crushes the snowpack and releases it into the side gutter.

When the snow shoveling work is completed, the user holds the grating handle 12 and gradually closes the grating 9 while retracting the grating handle 12.

Since the present invention is a snow-drifting gutter cover with the above-mentioned configuration, it is possible to charge and crush snow masses with a snow-breaking net, and therefore the snow masses can be effectively discharged into the gutter, making snow shoveling work more efficient. In addition, since the work of crushing snowpack can be omitted, frozen areas do not occur on or near the edge of the gutter, and the risk of slipping and injury can be eliminated.

In addition, after the door is closed, the grating has a large opening area so that sewage and rainwater can be discharged, and the bearing bar and twist bar act as anti-slips in any direction, making it safe for walking. It is effective.
