従来の地下埋設物の測定用蓋では、アンテナ部材を設けるために、蓋本体に凹部を形成しなければならない、という課題がある。 The conventional lid for measuring underground buried objects has a problem that a recess must be formed in the lid body in order to provide the antenna member.

本考案の地下埋設物の測定用蓋は、文字および絵柄の少なくとも一方を含む装飾部が底面から突出した装飾凹部、が表面に設けられた蓋本体と、装飾凹部に設けられ、測定器による地下埋設物の測定結果を示す測定信号電波を放射するアンテナ部材と、アンテナ部材が設けられた装飾凹部に充填された樹脂材と、を備えた。 The lid for measuring an underground buried object of the present invention is provided in a lid body having a decorative recess on the surface of which a decorative portion including at least one of a character and a pattern protrudes from the bottom surface, and a lid body provided in the decorative recess, and is underground by a measuring instrument. An antenna member that radiates a measurement signal radio wave indicating a measurement result of a buried object and a resin material filled in a decorative recess provided with the antenna member were provided.

この構成によれば、アンテナ部材の設置箇所として装飾凹部を利用することができる。したがって、アンテナ部材を蓋本体に設けるために装飾凹部とは別の凹部を形成する必要がなく、簡易にアンテナ部材を蓋本体に設けることができる。 According to this configuration, the decorative recess can be used as the installation location of the antenna member. Therefore, it is not necessary to form a recess different from the decorative recess in order to provide the antenna member on the lid body, and the antenna member can be easily provided on the lid body.

地下埋設物測定システムを示す図である。It is a figure which shows the underground buried object measurement system. マンホール蓋を示す図である。It is a figure which shows the manhole cover.

以下、添付の図面を参照して、本考案の一実施形態であるマンホール蓋1およびマンホール蓋1が設置された地下埋設物測定システムSyについて説明する。地下埋設物測定システムSyは、地下埋設物である上水道管7の漏水状態を測定する。 Hereinafter, the manhole cover 1 and the underground buried object measurement system Sy in which the manhole cover 1 is installed will be described with reference to the accompanying drawings. The underground buried object measurement system Sy measures the leak state of the water supply pipe 7 which is an underground buried object.

なお、地下埋設物は、上水道管7に限定されず、例えば、下水道管、ガス管、電力ケーブル、通信ケーブルなどでもよい。地下埋設物測定システムSyは、地下埋設物が下水道管である場合には、通水状態或いは水質を測定し、地下埋設物がガス管である場合には、ガス漏れ状態を測定し、地下埋設物が電力ケーブル或いは通信ケーブルである場合には、漏電状態或いは断線状態を測定する。 The underground buried object is not limited to the water supply pipe 7, and may be, for example, a sewer pipe, a gas pipe, a power cable, a communication cable, or the like. The underground buried object measurement system Sy measures the water flow state or water quality when the underground buried object is a sewer pipe, and measures the gas leak state when the underground buried object is a gas pipe, and underground burial. If the object is a power cable or a communication cable, measure the state of leakage or disconnection.

図1に示すように、地下埋設物測定システムSyは、マンホール蓋1と、測定器3と、記録器5とを備えている。マンホール蓋1は、上水道管7が設けられたマンホール9の地上開口部に設けられている。マンホール蓋1は、特に限定されないが、例えば制水弁蓋である。マンホール蓋1の詳細については、後述する。 As shown in FIG. 1, the underground buried object measuring system Sy includes a manhole cover 1, a measuring instrument 3, and a recorder 5. The manhole cover 1 is provided at the above-ground opening of the manhole 9 in which the water supply pipe 7 is provided. The manhole cover 1 is not particularly limited, but is, for example, a water control valve lid. Details of the manhole cover 1 will be described later.

測定器3は、マンホール9に設けられている。マンホール9には、測定器3のほか、弁室11と、弁操作部13とが設けられている。測定器3は、上水道管7の漏水状態を測定する。測定器3は、センサー15と、発信器17とを備えている。センサー15は、弁操作部13に設けられ、上水道管7から伝播してきた振動を検出する。発信器17は、ケーブル19を介して、マンホール蓋1が備えるアンテナ部材21と接続されている。発信器17は、センサー15の検出結果に基づく測定信号を、アンテナ部材21に出力する。 The measuring instrument 3 is provided in the manhole 9. In addition to the measuring instrument 3, the manhole 9 is provided with a valve chamber 11 and a valve operating unit 13. The measuring instrument 3 measures the leak state of the water supply pipe 7. The measuring instrument 3 includes a sensor 15 and a transmitter 17. The sensor 15 is provided in the valve operation unit 13 and detects the vibration propagated from the water supply pipe 7. The transmitter 17 is connected to the antenna member 21 included in the manhole cover 1 via a cable 19. The transmitter 17 outputs a measurement signal based on the detection result of the sensor 15 to the antenna member 21.

アンテナ部材21は、発信器17から受信した測定信号に基づいて、測定器3による上水道管7の測定結果を示す測定信号電波を地表空間に放射する。アンテナ部材21から放射された測定信号電波は、記録器5により受信される。 The antenna member 21 radiates a measurement signal radio wave indicating the measurement result of the water supply pipe 7 by the measuring instrument 3 to the ground surface space based on the measuring signal received from the transmitter 17. The measurement signal radio wave radiated from the antenna member 21 is received by the recorder 5.

記録器5は、アンテナ部材21から受信した測定信号電波に基づいて、測定器3による測定結果を記録する。観測者は、記録器5に記録された測定結果を観測する。なお、記録器5は、車31や人による運搬が可能な可搬式でもよく、電柱33等の支持体に固定された固定式でもよく、通信回線により中継局を介して測定信号電波を受信するネットワーク方式でもよい。 The recorder 5 records the measurement result by the measuring instrument 3 based on the measurement signal radio wave received from the antenna member 21. The observer observes the measurement result recorded in the recorder 5. The recorder 5 may be a portable type that can be carried by a car 31 or a person, or may be a fixed type that is fixed to a support such as a utility pole 33, and receives measurement signal radio waves via a relay station via a communication line. It may be a network method.

図2に基づいて、マンホール蓋1についてさらに説明する。マンホール蓋1は、蓋本体23と、アンテナ部材21と、樹脂材25とを備えている。 The manhole cover 1 will be further described with reference to FIG. The manhole cover 1 includes a lid main body 23, an antenna member 21, and a resin material 25.

蓋本体23は、例えば鋳鉄製であり、円板状に形成されている。蓋本体23の表面には、装飾凹部27が設けられている。装飾凹部27の形状は、特に限定されないが、例えば、長方形、円形、長円形などである。また、装飾凹部27の深さは、特に限定されないが、例えば5mm程度である。 The lid body 23 is made of cast iron, for example, and is formed in a disk shape. A decorative recess 27 is provided on the surface of the lid body 23. The shape of the decorative recess 27 is not particularly limited, but is, for example, a rectangle, a circle, an oval, or the like. The depth of the decorative recess 27 is not particularly limited, but is, for example, about 5 mm.

装飾凹部27の底面からは、装飾部29が突出している。装飾部29は、文字および絵柄の少なくとも一方を含む。図2に示した装飾部29は、文字「制水弁」を含んでいる。なお、文字とは、図2に示した漢字のほか、例えば、平仮名、片仮名、欧文字、数字、記号などを含む概念である。また、絵柄は、その表現対象は特に限定されないが、例えば、動物、植物、自然景観、建造物、装置、キャラクターなどを表現したものである。なお、装飾部29の突出高さは、装飾凹部27の周縁部と面一となる高さでもよく、装飾凹部27の周縁部よりも高くてもよく、装飾凹部27の周縁部よりも低くてもよい。 The decorative portion 29 protrudes from the bottom surface of the decorative recess 27. The decoration unit 29 includes at least one of a character and a pattern. The decorative portion 29 shown in FIG. 2 includes the character “water control valve”. In addition to the Chinese characters shown in FIG. 2, the character is a concept including, for example, hiragana, katakana, European characters, numbers, symbols, and the like. The object of expression of the pattern is not particularly limited, but is, for example, an animal, a plant, a natural landscape, a building, a device, a character, or the like. The protruding height of the decorative recess 29 may be a height that is flush with the peripheral edge of the decorative recess 27, may be higher than the peripheral edge of the decorative recess 27, or may be lower than the peripheral edge of the decorative recess 27. May be good.

アンテナ部材21は、装飾凹部27に設けられている。アンテナ部材21の形状は、装飾凹部27に設置可能であれば、特に限定されるものではない。なお、装飾凹部27の底面には、図示省略したが、アンテナ部材21の給電線を通すための給電穴が設けられている。 The antenna member 21 is provided in the decorative recess 27. The shape of the antenna member 21 is not particularly limited as long as it can be installed in the decorative recess 27. Although not shown, the bottom surface of the decorative recess 27 is provided with a feeding hole for passing the feeding line of the antenna member 21.

また、装飾凹部27には、樹脂材25が充填されている。樹脂材25により、アンテナ部材21の電気的絶縁を確保することができる。樹脂材25としては、例えば、エポキシ樹脂を用いることができる。樹脂材25の表面は、装飾凹部27の周縁部と面一でもよく、装飾凹部27の周縁部に対して突出していてもよく、装飾凹部27の周縁部に対して凹んでいてもよい。 Further, the decorative recess 27 is filled with the resin material 25. The resin material 25 can ensure the electrical insulation of the antenna member 21. As the resin material 25, for example, an epoxy resin can be used. The surface of the resin material 25 may be flush with the peripheral edge of the decorative recess 27, may protrude from the peripheral edge of the decorative recess 27, or may be recessed with respect to the peripheral edge of the decorative recess 27.

マンホール蓋1の製造方法は、特に限定されないが、例えば、アンテナ部材21を備えてはいないが装飾凹部27に樹脂材25が充填された既存のマンホール蓋を用いる場合、装飾凹部27から樹脂材を取り除き、給電穴を穿孔し、アンテナ部材21を装飾凹部27に配置すると共に給電線を配線した後、装飾凹部27に樹脂材25を流し込むことで、製造可能である。もちろん、既存のマンホール蓋を用いるだけでなく、新規のマンホール蓋1にも本実施形態を適用可能である。 The method for manufacturing the manhole lid 1 is not particularly limited. For example, when an existing manhole lid that is not provided with the antenna member 21 but is filled with the resin material 25 in the decorative recess 27 is used, the resin material is formed from the decorative recess 27. It can be manufactured by removing it, drilling a feeding hole, arranging the antenna member 21 in the decorative recess 27, wiring the feeding line, and then pouring the resin material 25 into the decorative recess 27. Of course, the present embodiment can be applied not only to the existing manhole cover but also to the new manhole cover 1.

以上のように、本実施形態のマンホール蓋1によれば、アンテナ部材21の設置箇所として装飾凹部27を利用することができる。したがって、アンテナ部材21を蓋本体23に設けるために装飾凹部27とは別の凹部を形成する必要がなく、簡易にアンテナ部材21を蓋本体23に設けることができる。また、マンホール蓋1の表面においては、アンテナ部材21を設ける前後でほとんど構造に変化がないため、道路上に設置されたマンホール蓋1が、歩行者や車両の通行の妨げとなることを防ぐことができる。 As described above, according to the manhole cover 1 of the present embodiment, the decorative recess 27 can be used as the installation location of the antenna member 21. Therefore, it is not necessary to form a recess different from the decorative recess 27 in order to provide the antenna member 21 in the lid main body 23, and the antenna member 21 can be easily provided in the lid main body 23. Further, since there is almost no change in the structure of the surface of the manhole cover 1 before and after the antenna member 21, the manhole cover 1 installed on the road is prevented from obstructing the passage of pedestrians and vehicles. Can be done.
