Description

[Detailed explanation of the invention] (Field of industrial application) This invention aims to melt the snow that has accumulated on the road by dumping it into a gutter.

(Prior art and problems) Conventionally, this type of snow melting device installed a perforated plate between the side walls of a gutter, and used it to remove snow accumulated on the upper side of the perforated plate and to stagnate water flowing below the perforated plate. There are types that are designed to melt the snow by using the gutter, and those that are devised to prevent large snow from falling to the bottom of the gutter by installing a protrusion in the middle of the side wall of the gutter to prevent snow from getting caught inside the gutter. There is.

However, the former type with perforated plates has the disadvantage that if the flow rate is small, the snow on the perforated plates cannot be melted, and the snow on the upstream side is particularly difficult to melt. In addition, the latter type of protrusion is not satisfactory because there is a risk that falling snow, dirt, etc. may get caught in the snow particles protruding from the bottom, causing running water to overflow from within the gutter.

(Means for solving the problem) This project was researched to solve the above-mentioned drawbacks of the snow melting device, and it is designed to constantly melt snow even with a small amount of running water, and also to prevent falling snow from getting caught. This is to prevent water from overflowing from inside the trench.

To describe the present invention in detail with reference to the illustrated embodiment, a surveying trench 1 is divided to the left and right from the bottom 3 of the surveying trench 1 by a sectioning body 2 installed along the flowing water direction, and the outside of the sectioning section 2 is covered with snow. The snow basin section 4 is defined as the water flow section 5, and the inside of the section body 2 is defined as the water flow section 5.The section section 2 consists of section sections 6, 6', etc. made of dogleg-shaped concrete plates, etc. It is installed with a water flow interval 7 between it and the water flow part 5, and the water flow interval 7 is set to prevent large snowflakes from falling into the water flow part 5, and is usually preferably about 10 cm.

The protrusions 8 provided at the lower ends of the section pieces 6, 6'... are fitted into the recesses 9 provided at the center of the bottom 3 of the measuring groove 1,
The upper part of each section piece 6, 6'... is the side wall 1 of the survey groove 1.
Tighten the bolt 12 to the nut 11 buried in the hole.

The shape of the section pieces 6, 6', . . . may be flat as shown in FIG. 3, or may be in an inverted U-shape or an inverted V-shape as shown in FIG. 4. Further, the water passage interval 7 may be partitioned by providing projections or the like at partial positions.

(Function) The present invention is implemented as described above, and its function will be explained as follows: The snow discarded in the survey trench 1 is packed on the outside of the section body 2, and at the same time it is gradually melted by the water flowing inside. The water that stagnated in the snow storage section 4 moves to the water flow section 5 inside the section body 2 through the water flow interval 7 and flows, and the snowpack that has fallen from the water flow interval 7 of the section field 2 flows through the water flow section 7. It flows through part 5.

(Effects) As mentioned above, this plan divides the field to the left and right from the bottom using a field structure with survey ditches installed along the direction of water flow, and the outside of the field field is used as a snow catchment area, and the inside of the field field is used for water flow. Water flow intervals were provided between the sections that make up the section so that the snow basin and water flow section communicate with each other, so even if the amount of water flowing in the gutter is small, the snow in the snow basin will not flow into the gutter. The snow that is in contact with the bottom is always gradually melted, and as the amount of water increases, the stagnant water in the snow pool moves through the water flow interval to the water flow part, and the water in this water flow part flows into the snow pool. It moves and constantly melts snow, accelerates the snow melting action, and is easy to install and remove, and can also be easily installed in an existing gutter.

Claims (1)

[Scope of utility model registration request] The field is divided from the bottom to the left and right by a field body with measuring grooves installed along the direction of water flow, with the outside of the field being a snow collection part and the inside of the field being a water flow part, forming a field body. A snow melting device is provided with a water flow interval between the sections so that the snow accumulation part and the water flow part communicate with each other.
