Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a snow melting device installed in a running waterway such as a side gutter. This relates to snow melting equipment.

[Prior Art] As a conventional snow melting device of this kind, for example, the Jikkyo 2-2
A technique disclosed in Japanese Patent No. 7023 is known. As shown in FIG. 6, this conventional device has a pair of partition walls 22 erected inside a flow channel 21, and each partition wall 22 extends the flow channel 21.
is divided into a main waterway 23 and a bypass waterway 24,
A plurality of water holes 25 are formed in the partition wall 22 at right angles to the water flow direction, and the water in the bypass waterway 24 is guided to the main waterway 23 through each water flow hole 25, and the snow S in the main waterway 23 is removed by the flowing water. is configured to melt.

In addition to the above-mentioned publication, the technique of forming a main waterway and a bypass waterway by providing a partition wall in a running waterway is disclosed in Japanese Utility Model Publication No. 64-46.
It is also disclosed in Japanese Utility Model Publication No. 2, Japanese Utility Model Publication No. 60-19192, and Japanese Utility Model Publication No. 60-19193.

[Problems to be Solved by the Invention] However, according to the conventional snow melting device, the water passage hole 25 is simply formed in the partition wall 22, and the direction of the water passage hole 25 is perpendicular to the water flow direction. Bypass waterway 2
There was a problem in that the force of the water flowing from the main waterway 23 through the water holes 25 was weak, and a sufficient snow melting effect could not be expected.

Further, since the partition wall 22 is a simple flat plate, its section modulus is small, and its strength is further reduced by the water passage holes 25, so it is easily deformed by the pressure of snow S, etc., and its durability is uncertain. To prevent this, it was necessary to form the partition wall 22 with a thick and heavy metal plate.

Furthermore, the upper end and the lower end of the partition wall 22 are connected to the flow channels 2 and 2, respectively.
Since the bulkhead 22 was fixed to the side wall 26 and bottom wall 27 of the bulkhead 1 with bolts 28, etc., once the bulkhead 22 was fixed, it could not be removed, and it remained attached even in spring, summer, and autumn when there is no snowfall. Ta. Therefore, dust may adhere to this partition wall 22, and rats may breed in the bypass water #I24.
There was a possibility that the flowing water capacity of flowing water #I21 would be reduced.

Therefore, the first object of the present invention is to increase the force of the water flowing from the bypass waterway to the main waterway to melt snow efficiently, and to increase the section modulus of the snow melting device so that it can be made thinner and lighter. The object of the present invention is to provide a snow melting device that can be made of a material.

Furthermore, the second object of the present invention is to allow the garbage to be stored in the waterway only during the winter season when there is snowfall, and to be easily removed during the spring, summer, and autumn seasons when there is no snowfall, thereby preventing the adhesion of debris. To provide a snow melting device that can prevent the breeding of rats, a decrease in the water flow capacity of a waterway, etc.

[Means for Solving the Problems] In order to solve the above problems, first of all, the snow melting device according to claim 1 has a partition wall erected opposite the inner surface of the side wall of the flow channel,
The partition wall forms a main channel and a bypass channel in the flow channel, and the partition wall is provided with a plurality of communication holes that communicate the main channel and the bypass channel, and a guide piece that protrudes from the communication hole toward the bypass channel side. The guide piece is configured to blow water from the bypass waterway into the main waterway through the communication hole.

Next, the snow melting device according to a second aspect of the present invention is configured such that the upper end of the partition wall is removably hooked to the upper end of the side wall.

Here, the above-mentioned "flow channel" is not limited to only side ditches, but also includes irrigation channels laid in fields, and the present invention can be applied to any of them.

The "bulkhead" is erected so as to face the inner surface of one or both side walls of the waterway at a predetermined interval and substantially parallel to it, and divides the waterway into two or three parts to the left and right, and separates the main waterway from the main waterway. A bypass waterway is formed.

Preferably, the partition wall is formed with a closed top surface so that snow thrown into the flow channel does not enter the bypass channel.

The "guide piece" projects obliquely or curvedly from the downstream edge of the communication hole toward the bypass waterway. When the partition wall is formed from a steel plate, the guide piece is cut and bent at a predetermined acute angle using a press at the same time as the communicating hole is bored.

[Function] According to the snow melting device according to claim 1, since the guide piece is provided in the communication hole of the partition wall so as to protrude toward the bypass waterway side, a part of the water flowing through the bypass waterway collides with the guide piece and flows toward the communication hole side. After being forcibly changed direction, it is forcefully blown out into the main waterway through the communication hole. Therefore, the energized water flow efficiently melts the snow in the main channel, and the sliding resistance between the snow surface and the partition wall is reduced. As a result, the snow is carried smoothly by the running water of the main waterway, and the stagnation in the waterway is quickly resolved.

In addition, the section modulus of the bulkhead increases due to the presence of the guide piece protruding toward the bypass waterway side, which increases the strength of the bulkhead and prevents it from deforming even when subjected to pressure from snow, etc., and improves durability. do. Furthermore, the partition wall can be formed of a material that is thinner and lighter than before.

Furthermore, according to the snow melting device according to claim 2, since the upper end of the partition wall is removably hooked to the upper end of the side wall, the partition wall can be attached to the flow channel only in winter when there is snowfall. , and can be easily removed in the spring, summer, and fall seasons when there is no snowfall. As a result, snow can be melted in winter, and other problems can be prevented, such as the adhesion of dirt to the snow melting device, the breeding of rats in the bypass waterway, and a decrease in the water flow capacity of the waterway.

[Example] Hereinafter, an example in which the present invention is embodied in a gutter snow melting device will be described with reference to the drawings.

As shown in FIG. 1, the side gutter 1 constituting the flow channel in this embodiment is constructed of an inverted U with an open bottom made of reinforced concrete from a pair of left and right side walls 2 and a connecting beam 3 connecting the upper ends of each side wall 2. It is shaped like a letter. An opening 4 is provided on the upper surface of the side gutter 1 adjacent to the connecting beam 3, and snow can be thrown into the side gutter 1 through this opening 4, but this opening 4 is not shown. It may be covered with a lid block, grating, etc. When constructing gutter 1, leave the bottom open or fill it with gravel, etc. so that some of the rainwater or melted snow can penetrate into the ground. Also, by post-casting concrete on the bottom, soil contamination by domestic or industrial wastewater can be prevented.

The snow melting device 5 of this embodiment is mounted inside one side wall 2 of the side gutter 1. The snow melting device 5 consists of a partition wall 6 formed from a steel plate and having a vertically elongated U-shape in cross section, with a hanging piece 7 on the upper part and an abutting piece 8 on the lower part. And interval! i! 6 removably hooks the hooking piece 7 to the upper end step of the side wall 2 and its edge 9, and abuts the abutting piece 8 against the inner surface of the lower part of the side wall 2, whereby a predetermined position is applied to the inner surface of the side wall 2. They are erected to face each other substantially parallel to each other at intervals. In this state, the water flow space of the side gutter 1 is divided into two left and right by the partition wall 6, and a wide main channel 10 and a narrow bypass water #111 are formed in the side gutter 1. In order to prevent snow thrown into the side gutter 1 from entering the bypass waterway 11, the partition wall 6 is formed with a closed top surface as described above. In FIG. 1, reference numeral 12 denotes a notch provided in the upper part of the partition wall 6 at a position corresponding to the connecting beam 3.

As shown in FIGS. 1 and 2, the upright portion of the partition wall 6 includes
