（産業上の利用分野）
本発明は液体貯蔵タンク内壁の推積物除去装置
に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for removing deposits from the inner wall of a liquid storage tank.
（従来技術）
液体貯蔵タンク、特にガソリン等の危険物を貯
蔵する地下タンクではタンクに漏洩があつても初
期発見が極めて困難、又は不可能であり、殆どの
場合漏れが拡大した後になつて発見され公害問題
となつている。(Prior art) In liquid storage tanks, especially underground tanks that store hazardous materials such as gasoline, even if there is a leak in the tank, it is extremely difficult or impossible to detect it at the beginning, and in most cases, it is discovered only after the leak has spread. It has become a pollution problem.
このような欠点を除くため従来フアイバースコ
ープでタンク内壁のサビ、スラツヂの状況、水の
有無その他の状況を目視し、写真撮影し、次いで
超音波厚さ計でタンクの板厚を測定することが行
われている。 In order to eliminate these drawbacks, it is conventional to use a fiberscope to visually observe the rust, sludge, presence or absence of water, and other conditions on the tank's inner wall, take photographs, and then measure the tank's thickness using an ultrasonic thickness gauge. It is being done.
然しながらタンクの板厚測定においては板の表
面に通常直径２mm程度の微少な凹凸が形成されて
いて厚さは場所によつて不均一であること、及び
サビ、スラツヂが推積していることの理由で正確
な測定を行うことが出来ず、従つて測定値に信頼
性がない欠点があつた。 However, when measuring tank plate thickness, the surface of the plate usually has minute irregularities of about 2 mm in diameter, and the thickness is uneven depending on the location, and it is estimated that rust and sludge are present. For some reason, accurate measurements could not be taken, and therefore the measured values were unreliable.
サビ、スラツヂの除去はこれをポンプで吸い取

に固着しているものは、ポンプの吸い取りのみで
は除去不可能であり、又回転ワイヤーブラシ等で
削り採る方法では前記板の凹凸のため正確になし
得ないばかりでなくタンク内が濁つてフアイバー
スコープで観察出来なくなる。 Rust and sludge can be removed by sucking it up with a pump, but rust and sludge that are stuck to the board cannot be removed just by sucking it up with a pump, and can be removed by scraping with a rotating wire brush, etc. This method not only cannot be used accurately due to the unevenness of the plate, but also makes the inside of the tank cloudy, making it impossible to observe with a fiberscope.

常時前記ピン６の先端が前記筒状体２の端面から
外方に例えば約15mm突出するようにする。 In the present invention, as shown in FIG. 1 and FIG.
A rotary suction hose 4 connected to a suction device and a rotating device (none of which are shown) is connected to the center opening 1 of the cylindrical body 2 with a height of about 50 mm, and the rotary suction hose 4 is connected to the outer periphery of the cylindrical body 2 in the axial direction. A plurality of holes 5, for example 20, extending into
are arranged concentrically, and a large number of pins 6 with sharp tips, each having a diameter of about 2 mm and a length of about 40 mm, for example, are slidably inserted into the hole 5. A compression spring is inserted between the collar 7 and the base of the hole 5 to restrain the pin 6 so that the tip of the pin 6 always projects outward from the end surface of the cylindrical body 2 by, for example, about 15 mm.
本発明液体貯蔵タンク内壁の推積物除去装置は

る。 Since the apparatus for removing deposits on the inner wall of a liquid storage tank of the present invention has the above-described configuration, when rotation is transmitted to the cylindrical body 2 through the rotary suction hose 4, the pin 6 rotates together with the cylindrical body 2, and this If the tip of the pin 6 is moved through the hose 4 while being pressed against the inner wall of the tank, rust and sludge on the inner wall of the tank can be easily removed by the tip of the pin 6, and the removed rust, Since the sludge is immediately transported to the outside through the opening 1 of the cylindrical body 2 and the rotating suction hose 4, the inside of the tank does not become cloudy, and the pin 6 is moved relative to the cylindrical body 2 according to the unevenness of the inner wall of the tank. Since it moves back and forth against the compression spring 8, it is possible to reliably remove rust and sludge from the entire inner wall of the tank.
尚本発明装置においては回転吸引ホース４の外
周に回転移動伝達用のチユーブを別に設け、これ

移動を伝達するようにしても良い。 In the device of the present invention, a tube for transmitting rotational movement is separately provided on the outer periphery of the rotary suction hose 4, and this tube is fixed to the outer periphery of the cylindrical body 2.
Movement may also be transmitted.
