Description

本考案は、例えば船舶係留用、観測用、標識用等として使用されるブイに関するものである。 The present invention relates to a buoy used, for example, for mooring a ship, for observation, for signage, and the like.

従来、例えば船舶係留用として使用されるブイは、海底のアンカーにチェーンを介して連結され、海面上または海中に位置するように設置されている（例えば、特許文献１参照。）。このブイは、中空状に形成された浮力体からなり、浮力体はゴム製の部材からなる軟質のものと、ポリエチレンフォームやシンタクチックフォームをウレタンで被覆した硬質のものがあり、何れも内部に空気が封入されている。
特開昭６１−１２９３９２号公報 Conventionally, for example, a buoy used for mooring a ship is connected to an anchor on the seabed via a chain and installed so as to be located on the sea surface or in the sea (see, for example, Patent Document 1). This buoy consists of a buoyant body formed in a hollow shape, and the buoyant body is either a soft one made of a rubber member or a hard one in which polyethylene foam or syntactic foam is coated with urethane. Air is enclosed.
JP 61-129392 A

しかしながら、軟質の浮力体からなるブイは、海中で使用される場合、水深が深くなると水圧の上昇により浮力体が収縮し、これにより浮力体の容積が減少して浮力が低下し、場合によっては海底まで沈むおそれもある。また、深い水深で使用するためには空気圧を高くする必要があるが、この場合は浮力体に耐圧性の高い材料を用いる必要があり、製造コストが高くなるという問題点があった。一方、硬質の浮力体からなるブイは、水圧による変形は少ないが、弾力性に欠ける分、衝突により損傷し易く、シンタクチックフォームを用いたものはコストも高いという問題点があった。 However, when a buoy made of a soft buoyancy body is used in the sea, the buoyancy body contracts due to an increase in water pressure when the water depth increases, thereby reducing the volume of the buoyancy body and lowering the buoyancy. There is also a risk of sinking to the sea floor. Further, in order to use it at a deep water depth, it is necessary to increase the air pressure. In this case, however, it is necessary to use a material having high pressure resistance for the buoyant body, and there is a problem that the manufacturing cost increases. On the other hand, a buoy made of a hard buoyant body has little deformation due to water pressure, but has a problem that it is easily damaged due to a collision because of its lack of elasticity, and a cost using a syntactic foam is high.

本考案は前記問題点に鑑みてなされたものであり、その目的とするところは、水圧に対する強度及び衝突に対する耐久性が高く、しかも低コストで製造することのできるブイを提供することにある。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a buoy that has high strength against water pressure and high durability against collision and can be manufactured at low cost.

本考案は前記目的を達成するために、浮力体を中空状のゴムによって形成してなるブイにおいて、前記浮力体の内部に補強部材を設けるとともに、補強部材を浮力体の内面に沿って形成している。 In order to achieve the above object, the present invention provides a buoy having a buoyant body made of hollow rubber, and a reinforcing member is provided inside the buoyant body, and the reinforcing member is formed along the inner surface of the buoyant body. ing.

これにより、例えば海面上で使用する場合、浮力体は弾力性のあるゴム製であるため、船舶等と衝突しても浮力体が容易に損傷することがない。また、海中で使用する場合は、水深が深くなると浮力体に加わる水圧が上昇するが、浮力体は補強部材によって内面側から補強されているため、水圧が上昇しても容易に収縮することがない。この場合、浮力体は補強部材によって補強されるので、浮力体に耐圧性の高い材料を用いる必要がない。 Thus, for example, when used on the sea surface, the buoyancy body is made of elastic rubber, and therefore the buoyancy body is not easily damaged even when it collides with a ship or the like. In addition, when used in the sea, the water pressure applied to the buoyancy body increases as the water depth increases, but the buoyancy body is reinforced from the inner surface side by the reinforcing member, so it can easily contract even if the water pressure increases. Absent. In this case, since the buoyancy body is reinforced by the reinforcing member, it is not necessary to use a material having high pressure resistance for the buoyancy body.

本考案のブイによれば、例えば海面上で使用する場合、船舶等と衝突しても浮力体が容易に損傷することがないので、衝突に対する耐久性を高めることができる。また、海中で使用する場合は、水深が深くなっても水圧により容易に収縮することがないので、水圧に対する強度を高めることができる。この場合、浮力体は補強部材によって補強されるので、浮力体に耐圧性の高い材料を用いる必要がなく、低コストで製造することができるとともに、浮力体内の空気圧を低くすることができ、高圧による浮力体の破裂を防止することができる。 According to the buoy of the present invention, for example, when used on the sea surface, even if it collides with a ship or the like, the buoyancy body is not easily damaged, so the durability against the collision can be enhanced. In addition, when used in the sea, the strength against water pressure can be increased because the water pressure does not easily shrink even when the water depth increases. In this case, since the buoyancy body is reinforced by the reinforcing member, it is not necessary to use a material having high pressure resistance for the buoyancy body, and the buoyancy body can be manufactured at a low cost, and the air pressure in the buoyancy body can be lowered, It is possible to prevent the buoyancy body from being ruptured.

図１は本考案の一実施形態を示すブイの一部断面側面図である。 FIG. 1 is a partial sectional side view of a buoy showing an embodiment of the present invention.

このブイは、中空状に形成された浮力体１と、浮力体１の内部に設けられた補強部材２とからなり、アンカーチェーン３を介して海底のアンカー４に連結され、例えば船舶や洋上基地等の浮体式構造物の係留用に使用されるものである。 This buoy includes a buoyancy body 1 formed in a hollow shape and a reinforcing member 2 provided inside the buoyancy body 1, and is connected to an anchor 4 on the seabed via an anchor chain 3, for example, a ship or an offshore base It is used for mooring floating structures such as.

浮力体１は縦長の長円形に形成され、繊維で補強されたゴム製の部材からなる。浮力体１は内部に空気が封入されるとともに、上端に船舶側のチェーン（図示せず）と連結するための連結部１ａを有し、下端にはアンカーチェーン３に連結される連結部１ｂが設けられている。 The buoyancy body 1 is formed of a rubber member formed in a vertically long oval shape and reinforced with fibers. The buoyancy body 1 is filled with air and has a connecting portion 1a for connecting to a ship side chain (not shown) at the upper end, and a connecting portion 1b connected to the anchor chain 3 at the lower end. Is provided.

補強部材２はゴムチューブ等の可撓性の管状部材からなり、浮力体１の内面に沿って螺旋状に形成されている。補強部材２は両端を閉塞するとともに、その内部には空気が充填され、空気の圧力によって補強部材２が浮力体１の内面に押圧されるようになっている。また、補強部材２の一端には浮力体１の外部から空気を充填するためのホース２ａが接続され、ホース２ａは図示しないバルブによって開閉するようになっている。 The reinforcing member 2 is made of a flexible tubular member such as a rubber tube, and is formed in a spiral shape along the inner surface of the buoyancy body 1. The reinforcing member 2 is closed at both ends, and the inside thereof is filled with air, and the reinforcing member 2 is pressed against the inner surface of the buoyant body 1 by the pressure of the air. In addition, a hose 2a for filling air from the outside of the buoyancy body 1 is connected to one end of the reinforcing member 2, and the hose 2a is opened and closed by a valve (not shown).

以上のように構成されたブイは、浮力体１をアンカーチェーン３に連結され、海面上または海中に位置するように設置される。このブイを海面上で使用する場合、浮力体１は弾力性のあるゴム製であるため、船舶等と衝突しても浮力体１が容易に損傷することがない。また、海中で使用する場合は、水深が深くなると浮力体１に加わる水圧が上昇するが、浮力体１は補強部材２によって内面側から補強されているため、水圧が上昇しても容易に収縮することがない。 The buoy configured as described above is installed so that the buoyancy body 1 is connected to the anchor chain 3 and located on the sea surface or in the sea. When this buoy is used on the sea surface, the buoyancy body 1 is made of elastic rubber, so that the buoyancy body 1 is not easily damaged even if it collides with a ship or the like. Further, when used in the sea, the water pressure applied to the buoyancy body 1 increases as the water depth increases. However, since the buoyancy body 1 is reinforced from the inner surface side by the reinforcing member 2, it easily contracts even when the water pressure increases. There is nothing to do.

このように、本実施形態のブイによれば、浮力体１をゴムによって形成するとともに、浮力体１の内部に補強部材２を設け、補強部材２を浮力体１の内面に沿って形成したので、海面上で使用する場合、船舶等と衝突しても浮力体１が容易に損傷することがなく、衝突に対する耐久性を高めることができる。また、海中で使用する場合は、水深が深くなっても水圧により容易に収縮することがなく、水圧に対する強度を高めることができる。この場合、浮力体１は補強部材２によって補強されるので、浮力体１に耐圧性の高い材料を用いる必要がなく、低コストで製造することができるとともに、浮力体１内の空気圧を低くすることができ、高圧による浮力体１の破裂を防止することができる。 Thus, according to the buoy of the present embodiment, the buoyancy body 1 is formed of rubber, the reinforcement member 2 is provided inside the buoyancy body 1, and the reinforcement member 2 is formed along the inner surface of the buoyancy body 1. When used on the sea surface, the buoyancy body 1 is not easily damaged even if it collides with a ship or the like, and durability against the collision can be enhanced. Moreover, when used in the sea, even if the water depth becomes deep, it does not easily contract due to water pressure, and the strength against water pressure can be increased. In this case, since the buoyancy body 1 is reinforced by the reinforcing member 2, it is not necessary to use a material having high pressure resistance for the buoyancy body 1, it can be manufactured at low cost, and the air pressure in the buoyancy body 1 is lowered. And rupture of the buoyancy body 1 due to high pressure can be prevented.

また、補強部材２を可撓性の管状部材によって形成し、その内部に空気を封入することにより、補強部材２に浮力体１の内面への押圧力を付与するようにしたので、補強部材２をゴムチューブ等の安価な材料によって低コストに形成することができるとともに、補強部材２内の空気圧によって浮力体１を確実に補強することができる。 Further, since the reinforcing member 2 is formed of a flexible tubular member and air is enclosed therein, the pressing force to the inner surface of the buoyant body 1 is applied to the reinforcing member 2. Can be formed at low cost by an inexpensive material such as a rubber tube, and the buoyancy body 1 can be reliably reinforced by the air pressure in the reinforcing member 2.

この場合、補強部材２を螺旋状に形成したので、補強部材２を浮力体１の内面に沿うように連続して形成することができ、部品点数を少なくすることができる。 In this case, since the reinforcing member 2 is formed in a spiral shape, the reinforcing member 2 can be continuously formed along the inner surface of the buoyancy body 1 and the number of parts can be reduced.

尚、前記実施形態では、補強部材２内に充填される流体として空気を用いたものを示したが、窒素等の気体や水等の液体を充填するようにしてもよい。また、前記実施形態では、補強部材２を管状部材によって形成し、内部に流体を充填するようにしたものを示したが、補強部材２を管状でない無垢のゴム製部材または鋼製部材によって螺旋状に形成するようにしてもよい。 In the above-described embodiment, air is used as the fluid filled in the reinforcing member 2, but a gas such as nitrogen or a liquid such as water may be filled. Moreover, in the said embodiment, although the reinforcement member 2 was formed by the tubular member and filled with the fluid inside, the reinforcement member 2 was spirally formed by a solid rubber member or steel member that is not tubular. You may make it form in.

図２は本考案の他の実施形態を示すブイの一部断面側面図であり、前記実施形態と同等の構成部分には同一の符号を付して示す。 FIG. 2 is a partial cross-sectional side view of a buoy showing another embodiment of the present invention, and the same reference numerals are given to the same components as those in the above embodiment.

本実施形態のブイは、前記螺旋状の補強部材２に代えて、浮力体１の内面に沿って形成された複数のリング状の補強部材５を有し、各補強部材５を浮力体１内に互いに上下方向に間隔をおいて配置したものである。この場合、各補強部材５には管状でない無垢のゴム製部材または鋼製部材が用いられる。 The buoy of the present embodiment has a plurality of ring-shaped reinforcing members 5 formed along the inner surface of the buoyancy body 1 in place of the helical reinforcement member 2, and each reinforcement member 5 is placed inside the buoyancy body 1. Are arranged at intervals in the vertical direction. In this case, each reinforcing member 5 is a solid rubber member or steel member that is not tubular.

本実施形態によれば、浮力体１の内面に沿って形成された複数の補強部材５によってゴム製の浮力体１を補強するようにしたので、前記実施形態と同様、水圧に対する強度及び衝突に対する耐久性を高めることができるとともに、低コストで製造することができる。 According to the present embodiment, since the rubber buoyancy body 1 is reinforced by the plurality of reinforcing members 5 formed along the inner surface of the buoyancy body 1, the strength against water pressure and the collision are the same as in the previous embodiment. The durability can be increased and the manufacturing can be performed at low cost.

また、本実施形態では、各補強部材５をリング状に形成して浮力体１内の複数箇所に設けたので、浮力体１の大きさや仕様に応じた数の補強部材５を用いることができ、部品の共通化を図ることができる。 Moreover, in this embodiment, since each reinforcement member 5 was formed in the ring shape and provided in the several places in the buoyancy body 1, the number of reinforcement members 5 according to the magnitude | size and specification of the buoyancy body 1 can be used. The parts can be shared.

尚、本実施形態では、各補強部材５を管状でない無垢のリング状部材によって形成したものを示したが、前記実施形態のように各補強部材５を管状の部材によって形成し、内部に気体や液体等の流体を充填するようにしてもよい。 In the present embodiment, each reinforcing member 5 is formed of a solid ring-shaped member that is not tubular. However, as in the above-described embodiment, each reinforcing member 5 is formed by a tubular member, and gas or You may make it fill with fluids, such as a liquid.
