Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) This invention relates to a snow-driving water treatment device that is attached to the intermediate and terminal parts of a snow-driving groove.

(Prior art) As is well known, in areas with heavy winter snowfall, the equipment used to remove snow from roads and other areas to ensure traffic flow includes not only large snow removal machines, but also large snow removal equipment that removes snow from roads, etc. Equipment that uses snow melting nozzles to melt snow while spraying well water or river water, and equipment that uses road heating to melt snow are used, but the operation of these equipment requires a very large amount of money. In contrast, snow removal methods using snow ditches that use irrigation canals that run along the roadside can remove snow all at once with the cooperation of local residents if a sufficient amount of running water can be secured. It is an extremely useful snow removal equipment as it can remove large amounts of snow.

(Problem to be solved by the invention) However, the snow drifting ditch described above is not a device that melts snow into water and flows it away, but is a device that transports snow from upstream to downstream using water as a moving medium. If the relationship between the amount of water in the snow ditch, the flow velocity, and the amount of snow thrown is not maintained above certain conditions, snow masses will accumulate in various places in the snow ditch, forming a dam, and blocking the flow of water. There is a drawback that it overflows onto the road surface. Recently, as a means to solve this problem, attempts have been made to install a rotary snow crushing device with spiral rotating blades in the snow drift groove to forcefully move the snow downstream while crushing it into small pieces. However, the specific gravity of snowflakes abandoned in ditches is much lighter than that of water, and due to the difference in specific gravity, there is a strong tendency for them to be pushed up in the direction of floating on the water surface. Because they had to be moved around a lot and could not fully demonstrate their expected snow-breaking ability, the results were far from practical.

The drifting snow water treatment device according to the present invention was devised in order to deal with the above-mentioned problem, and its purpose is to treat the drifting snow water that flows through the snow ditch in a mixture of snowpack and water. To provide, at low cost, a drifting snow water treatment device having a function of changing the water into almost liquid shearbet shape and discharging it at the middle part or end part of a drifting snow groove.

[Structure of the idea]

(Means for Solving the Problems) The structure of the snow water treatment device according to the present invention to achieve the above object is that one side of the tank body has a snow water inlet connected to a snow groove, and the other side has a snow water inlet for water treatment. The present invention is characterized in that a submersible pump having both the function of sucking and discharging snow water and the function of stirring it is installed inside a treatment tank provided with a water outlet.

(Function) The device of the present invention crushes and melts the snowpack mixed in the water while agitating the drifting snow water introduced into the treatment tank by the suction and discharge action of the submersible pump, and converts this snow water into a shear bed-like fluid. It is transformed into the body and rapidly released from the outlet.

(Example) Hereinafter, the structure and operation of the drifting snow water treatment device according to the present invention will be explained in detail with reference to the drawings of the example. In the case of this embodiment, the tank body 1 of the treatment tank T is formed into a box shape from a material such as reinforced concrete, and its internal volume is determined by the water flow cross-sectional area of the snow groove, the flow rate, the amount of snow thrown, and the installation of the treatment tank T. It is determined according to the conditions such as the position and the number of arrangement, and there is a snow water inlet 3 connected to the snow groove 2 at the top of one side of the tank body 1, and a drainage channel 4 or the snow groove 2 at the top of the other side. Treated water outlet 5 connected to
In addition, manholes 7 and drainage pipe through-holes 8 are provided at important points in the lid 6, and at the bottom of the tank 1, there is an underwater pipe that can pump crushed snow along with water. A pump 9 is installed, and a discharge pipe 10 is provided on the discharge side of the submersible pump 9, which connects to the drainage channel 4 through the drainage pipe through hole 8.
In the middle part of 0, there is a branch pipe 12 with a control valve 11.
is branched and attached at a position lower than the normal water level in the tank body 1.

Since the drifting snow water treatment device of the present invention has the above-mentioned structure, this device can be placed at the middle or end of the snow drifting groove 2 depending on the water flow cross-sectional area and length of the snow drifting groove 2. If the submersible pump 9 is driven while introducing the snow water W ₁ mixed with the snow mass S and water W from the snow drift groove 2 into the processing tank T, from the suction port 9a of the submersible pump 9, Not only water W but also relatively small snowflakes S mixed in the water are sucked in together with the water W, and the snowflakes S are finely crushed in the submersible pump 9 and changed into a shearbet-like form, which is then used as treated water.
_W2 is discharged from the discharge port 9b through the discharge pipe 10 into the discharge passage 4, and a part of it, mainly water W not mixed with snow, is returned to the water inside the tank body 1 from the branch pipe 12.

Therefore, in the case of the device of the present invention, inside the treatment tank T, the returning water vigorously discharged from the branch pipe 12 stirs the drifting snow water _W1 in the tank as shown by the arrow. Since the operation of mixing with the succeeding snow water W ₁ that flows in from the snow drift groove 2 one after another is constantly repeated, large snow masses S float on the surface of the snow water W ₁ that has flowed into the tank. Never stagnate,
Furthermore, if high-temperature well water (13°C), sewage water (20°C), river water (5°C), etc. is used as the water W to be fed to the snow drifting groove 2 as a conveying medium, the flow inside the treatment tank T will be reduced. When the snow water W ₁ is stirred, the snow mass S is melted at the same time, so that the processing capacity can be dramatically improved.

[Effect of idea]

As described above, if the device of the present invention is installed in the middle part of the snow groove or the final treatment part to treat the snow water, the snow water introduced from the snow groove into the treatment tank can be transferred to the submersible pump. It is possible to crush and melt the snowpack mixed in the water while agitating it by suction and discharging action, and change this snowfall water into a shearbed-like fluid that can be rapidly discharged from the outlet, making it possible to remove snow by using a snowflow groove. By maximizing its capabilities, it will make a significant contribution to securing transportation and living space in areas with heavy winter snowfall.
