Abstract

PURPOSE:To take in water flowed in from an opening from a frozen surface easily, safely, and rapidly by dropping a weight suspended through a chain to destruct a pipe bottom plate held on the frozen surface by a floating material. CONSTITUTION:A bottom surface is closed by a bottom plate 1, and a hollow body 2 in which a weight 6 is suspended from a weight holder 4 provided at a top cover 7 through a chain is floated on a water surface A-A' by a floating material 3 so that it is kept at that position even if frozen occurs. When water is taken in, a holding wedge 5 is pulled out from a weight holder 4, and the bottom plate 1 is driven out by dropping the weight 6 to fall it to a water bottom. Water under the frozen surface which was enclosed by the bottom plate 1 is risen in the body 2 to water level balanced with the atmospheric pressure. Here the top cover 7 is opened, and a water feed hose end, underwater pump, and the like are inserted from its opening for water intake.

Description

【発明の詳細な説明】 （イ）産業上の利用分野 本発明は結氷した水面から取水を容易に行うための器具
に関するものである。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a device for easily taking water from a frozen water surface.

（ロ）従来の技術 従来結氷面より取水をする場合はハンマー等を使用して
人力で結氷面に打撃を与え氷に穴を開けるか鋸等切削工
具を使用して氷を切断して穴を開けて行うことが一般的
である。(B) Conventional technology Conventionally, when water is taken from the freezing surface, a hammer is used to manually hit the freezing surface to make holes in the ice, or a cutting tool such as a saw is used to cut the ice to make holes. It is common to open it.

（ハ）発明が解決しようとする課題 従来の方法は作業者の落水や作業時の氷の破片の飛散に
よる負傷等の危険が多い。また火災消火用の取水の場合
は取水開始までの時間短縮が大きな課題となる。本発明
は結氷面より取水する場合の労力を低減して、安全性を
向上させ取水開始までの時間を短縮することを目的とす
るものである。(C) Problems to be Solved by the Invention In the conventional methods, there are many risks such as operator's falling of water and injury due to scattering of ice fragments during operation. In the case of water intake for fire extinguishing, shortening the time before starting water intake is a major issue. It is an object of the present invention to reduce the labor required when water is taken from the freezing surface, improve safety, and shorten the time until the start of water intake.

（ニ）課題を解決するための手段 水は摂氏４度で比重が最大になり結氷の始まる摂氏０度
では比重が小さくなるので表面から結氷し順次氷の厚さ
を増すかたちで結氷が進行して行く。この性質を利用し

ことのできる開口部を設け内部に空気等を密封して断熱
性を持たせる。(D) Means for solving the problem The specific gravity of water becomes maximum at 4 degrees Celsius, and the specific gravity becomes small at 0 degrees Celsius where ice begins to form. Go. By utilizing this property, a sealed container such as a pipe is pierced to a position deeper than the ice thickness expected in advance, and it is opened at the part that appears on the ice during freezing and the part where the ice does not freeze when necessary. An opening that can be opened is provided, and air or the like is sealed inside to provide heat insulation.

（ホ）作用 取水が必要になった場合は氷上の部分と結氷しない深さ
の部分の開口部を開いて氷上の開口部からホース端や水
中ポンプ等を挿入して結氷しない深さの開口部から取水
を行う。(E) Action When water needs to be drawn, open the opening on the ice and the portion where the ice does not freeze, and insert a hose end or submersible pump through the opening on the ice to open the ice. Take water from.

う。(F) Description based on Examples An explanation will be given using the ice surface water intake device shown in FIG. 1 as an example. The hollow main body sealed by the bottom plate floats on the water surface (AA ') by the floating material and stays at the same position even when ice forms. If water intake is required, remove the holding wedge from the weight holder and drop the weight. The dropped weight punches out the bottom plate and falls to the bottom of the water. The water below the freezing surface, which was sealed by the destroyed bottom plate, flows into the main body to a water level balanced with atmospheric pressure. Open the top cover and insert the end of the water supply hose or submersible pump from the opening to take water from below the freezing surface.

（ト）発明の効果 この発明に係わる取水器を使用すれば熟達した作業者で
なくても結氷面からの取水を安全かつ迅速に行うことが
できる。(G) Effect of the Invention By using the water intake device according to the present invention, water intake from the freezing surface can be safely and quickly performed even by an unskilled operator.
