本発明は汚染された水底の汚泥、例えば原子炉
設備のプール底の放射性汚泥の吸引除去に使用す
る自走水底クリーナーに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a self-propelled underwater bottom cleaner used for suctioning and removing contaminated sludge from the bottom of a water body, such as radioactive sludge from the bottom of a pool in a nuclear reactor facility.
従来の水底クリーナーは液に接する回転部の軸
封の完全化が難しかつたので、内部に空気ボンベ
を装着し、汚染水の浸入を遮断する方法をとつて
いた。 In conventional underwater bottom cleaners, it was difficult to completely seal the shaft of the rotating part that came into contact with the liquid, so an air cylinder was installed inside to prevent the ingress of contaminated water.
又複雑な外形をもち車載機器類はそのまゝ汚染
水に接液するか、又は機器要部のみ大きな空気溜
カバーを以て覆う等の試みがなされていた。この
為、作業終了後の機器除染は困難をきわめ、又大
きな空気溜は不均衡な浮力を生ずるので、車体の
不安定化や駆動牽引力の不足を招く原因となつて
いた。 In addition, attempts have been made to either expose in-vehicle equipment that has a complicated external shape to contaminated water, or to cover only the main parts of the equipment with large air reservoir covers. For this reason, decontamination of equipment after work is extremely difficult, and large air pockets create unbalanced buoyancy, leading to instability of the vehicle body and lack of driving traction force.
本発明は上述した従来技術の欠点を解決すべく
発明されたもので、添付図面を参照して実施例に
ついて説明する。 The present invention was invented to solve the above-mentioned drawbacks of the prior art, and embodiments thereof will be described with reference to the accompanying drawings.
１は例えばステンレス板にて形成された車体を
構成するための箱体である。箱体１には駆動車輪
８が左右にとりつけられている。９はかじ取車輪
で、箱体の底部に設けられている。１０は箱体１
の進行方向前後にとりつけられた汚泥の吸引ノズ
ルで、下端に掻き板がとりつけられ、水底の汚泥
をかき寄せ易くなつている。 Reference numeral 1 denotes a box body made of, for example, a stainless steel plate for constructing a vehicle body. Driving wheels 8 are attached to the left and right sides of the box body 1. 9 is a steering wheel, which is provided at the bottom of the box body. 10 is box body 1
A sludge suction nozzle is attached to the front and back of the water in the direction of movement, and a scraping plate is attached to the bottom end to make it easier to scrape up sludge from the bottom of the water.
箱体１の内部には駆動モータ３、かじ取モータ
４、かじ取モータ４とかじ取車輪９を連結するリ
ンク機構６、ポンプ５、吸引ノズル１０，１０に
通ずる配管７が内蔵され、かつ箱体１の内部には
清水２が充満されている。 A drive motor 3, a steering motor 4, a link mechanism 6 connecting the steering motor 4 and the steering wheels 9, a pump 5, and piping 7 leading to suction nozzles 10, 10 are built into the box 1. The inside of the body 1 is filled with fresh water 2.
１１は排泥ホースで、ポンプ５で吸引した汚泥
はこの排泥ホース１１を介し外部に排出される。
１２は給水ならびに駆動モータ３、ポンプ５駆動
用の圧縮空気供給用のホース群である。なお１３
は水面である。 Reference numeral 11 denotes a sludge discharge hose, and the sludge sucked by the pump 5 is discharged to the outside through this sludge discharge hose 11.
Reference numeral 12 denotes a group of hoses for supplying water and compressed air for driving the drive motor 3 and pump 5. Note 13
is the water surface.
以上の構成であるから、汚泥排出に際しては、
外部からの圧縮空気で駆動モータ３を起動してポ
ンプ５を作動し、排泥ホース１１から水底の汚泥
を排出するが、箱体１内には常時水封用の静水圧
以上の圧力を有する清水２が満されているので、
車載機器が汚染されることがない。 With the above configuration, when discharging sludge,
The drive motor 3 is started with compressed air from the outside to operate the pump 5, and the sludge at the bottom of the water is discharged from the sludge discharge hose 11, but the pressure inside the box body 1 is always higher than the hydrostatic pressure for water sealing. Since Shimizu 2 is filled,
In-vehicle equipment will not be contaminated.
又駆動部は外部から供給される圧縮空気により
駆動され、その空気圧が箱体外の水圧より大であ
るので、軸封部から内部への浸水がない。 Further, the drive section is driven by compressed air supplied from the outside, and since the air pressure is greater than the water pressure outside the box, there is no possibility of water seeping into the interior from the shaft seal.
車体を形成する箱体１の外板を平滑なステンレ
ス製で構成するならば、ステンレス壁の除染が容
易である。 If the outer panel of the box 1 forming the vehicle body is made of smooth stainless steel, the stainless steel walls can be easily decontaminated.
従来のごとく、軸封のための空気ボンベ、車載
機器類の覆いのための空気溜等を用いないので、
浮力が生ぜず、車体はきわめて安定し、走行時に
おけるけん引力を十二分にとることができる。 Unlike conventional models, air cylinders for shaft sealing and air reservoirs for covering onboard equipment are not used, so
There is no buoyancy, the vehicle body is extremely stable, and it can provide more than enough traction when driving.
