Description
本考案は、灯油タンク配管からの灯油の異常流出を監視する装置に関する。The present invention relates to an apparatus for monitoring an abnormal outflow of kerosene from a kerosene tank pipe.
従来、灯油ホームタンクからの灯油の盗難を防止するために、灯油ホームタンクに付設する給油口に盗難防止用のカバーを取り付け施錠する例がある（例えば、特許文献１参照）。Conventionally, in order to prevent kerosene from being stolen from the kerosene home tank, there is an example in which an antitheft cover is attached and locked to an oil supply port attached to the kerosene home tank (see, for example, Patent Document 1).
まずは、灯油ホームタンクからの灯油の盗難について説明する。
特許文献１は、灯油ホームタンク付設の給油口、及び油量計を覆う盗難防止カバーを取り付けホームタンク内の灯油の盗難を阻止しようとするものである。
しかし、現在の灯油ホームタンクからの盗難は、給油口から吸い上げるものではなく、ホームタンク下部の配管をカットし灯油を抜き取る方法で行われている場合もあり、従前の方式では盗難を防止することはできなくなっている。First, the theft of kerosene from the kerosene home tank will be described.
However, theft from the current kerosene home tank is not sucked up from the refueling port, it may be done by cutting the piping under the home tank and extracting kerosene, and the conventional method prevents theft Is no longer possible.
次に天災や、事故等により灯油が漏洩する場合を説明する。一般住宅や小規模建物の建物内部への灯油の供給は、ホームタンクより建物の外壁周囲の地中近くに配管を埋設し、建物内部の暖房機・ボイラーに供給している。使用配管類も頑丈なものではなく、天災や事故等により、給油配管等の劣化破損・切断事故による破損などの異常で油漏れが発生する。土中埋設にある配管等の事故で灯油が漏洩した場合、地中内の漏洩状況を把握することは非常に困難であるし、又建物廻りの配管距離が長いことから、発見するのが容易ではない。しかも発見される時点では、建物の周りでの異常臭気で発覚されることが多い。少量の漏洩事故は発生に気づくこともなく、土壌汚染、水質汚染になっている。又、漏れの量が多い場合は、土壌内での汚染はもとより、地下水まで被害が及んだり、道路側溝を経由し、河川まで灯油が流れだす危険性も考えられる。これらの状況にあって、少量の漏洩事故を防止する適切な技術は見当たらない。
本考案は、上記の状況に鑑み、灯油の盗難などの大量の流出事故の防止はもとより、少量の漏洩事故をも防止する監視装置を提供しようとするものである。Next, a case where kerosene leaks due to a natural disaster or an accident will be described. The supply of kerosene to the interior of ordinary houses and small buildings is buried near the ground around the outer wall of the building from the home tank and supplied to the heater and boiler inside the building. The piping used is not sturdy, and due to natural disasters and accidents, oil leaks occur due to abnormalities such as deterioration of oil supply piping and damage caused by cutting accidents. If kerosene leaks due to an accident in a pipe or the like buried in the soil, it is very difficult to ascertain the leak condition in the ground, and the piping distance around the building is long, making it easy to detect is not. Moreover, at the time of discovery, it is often detected by abnormal odor around the building. A small amount of leakage accidents are not noticed and have caused soil and water pollution. In addition, if the amount of leakage is large, there is a risk that the groundwater will be damaged as well as contamination in the soil, or that kerosene will flow to the river via the road gutter. Under these circumstances, there is no appropriate technology to prevent a small amount of leakage accident.
In view of the above situation, the present invention is intended to provide a monitoring device that prevents a large amount of leakage accidents such as theft of kerosene as well as a small amount of leakage accidents.
前記の課題を解決するため、本考案は、灯油タンク出口近傍の配管に流量計を設け、暖房機に電流感知センサーを設け、前記流量計の電流信号と前記暖房機の電流感知センサー信号の比較により、暖房機不使用時に流量計電流信号が生じた時に、異常時に警報装置を作動することを特徴とする灯油漏洩感知器。In order to solve the above-mentioned problems, the present invention provides a flow meter in the piping near the kerosene tank outlet, a current sensor in the heater, and compares the current signal of the flow meter with the current sensor signal of the heater. The kerosene leak detector is characterized in that, when a flow meter current signal is generated when the heater is not used, an alarm device is activated in the event of an abnormality.
本考案により灯油の盗難、環境汚染対策、土質・水質汚染の防止対策ができる。 The present invention can take measures to prevent kerosene theft, environmental pollution, and soil and water pollution.
以下、本考案の実施の形態を図を用いて詳細に説明する。
図１は、灯油ホームタンク１から建物７の内部に灯油を供給する簡略図である。
灯油は、灯油ホームタンク１から灯油配管４により地中を通り、建物内部の灯油ストーブやボイラーなどの暖房機５に供給される。灯油ホームタンク１の下部に設けられる流出口近傍の配管に灯油の流量計３を設ける。灯油の配管の流れは、流量計の出力信号の電流Ａとして、有線又は無線により受信する。
また、建物内部の暖房機５への電気配線に電流感知センサー８を設ける。暖房機５が運転中の時、暖房機の稼働信号として電流感知センサー８の信号電流Ｂを受信する。本考案は、流量計の出力信号と暖房機の電流感知センサー信号を制御回路側で受信し、両者の比較により、異常を検出する。
灯油配管の途中のどこででも液漏れ、盗難の可能性がある。
暖房機を使用していないとき、すなわち暖房機に電流Ｂが流れていない時に、流量計の電流Ａが感知されるときは、何らかの液漏れが発生している事になり、屋内または屋外に設置された警報装置６が作動する。警報は、ベル、ランプ、音声などとする。
一般家庭の外部設置の４９０Ｌタンクでのタンク・配管・抜き取り事故に使用するほか、環境汚染対策（土質・水質）として、流体を扱う作業工場等での送り側と受け側との異常事故時に非常警報する安全装置として利用することができる。Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

There is a possibility of liquid leakage or theft anywhere in the kerosene piping.
When the heater is not used, that is, when the electric current B is not flowing through the heater, if the current A of the flowmeter is detected, some liquid leakage has occurred and it is installed indoors or outdoors. The
In addition to being used for accidents involving tanks, piping, and extraction with externally installed 490L tanks in general households, as an environmental pollution measure (soil and water quality), it is an emergency when there is an abnormal accident between the sending side and the receiving side in a factory that handles fluids It can be used as a safety device for alarming.
