本発明は走行式汚物吸引装置に係り、特に水が封入され
たタンク底面を走行し、タンク底面の堆積物をタンク外
に排出する走行式汚物吸引装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a traveling filth suction device, and more particularly to a traveling filth suction device that travels on the bottom of a tank filled with water and discharges deposits on the bottom of the tank to the outside of the tank.
原子力発電所等に於いては、水が封入されたタンク底部
に堆積した放射性汚染物質は外部に取出す必要がある。In nuclear power plants and the like, radioactive contaminants deposited at the bottom of tanks containing water must be taken out.
このようなタンク底部に堆積した汚染物質は、吸込ポン
プを備えた汚物吸引装置をタンク底面を走行させ、吸込
ポンプによって放射性汚染物質を吸引すると共にタンク
外部に排出するようにしている。To deal with such contaminants deposited at the bottom of the tank, a filth suction device equipped with a suction pump is run along the bottom of the tank, and the suction pump sucks up the radioactive contaminants and discharges them to the outside of the tank.

た。Conventionally, a traveling type filth suction device has been proposed that uses an electric motor as the drive source, but if such an electric motor is used as the drive source, the filth suction device itself will have electrical instrumentation parts. is enclosed in a sealed box to prevent water and electrical leakage. Therefore, such a conventional filth suction device has a disadvantage in that a weight is provided to cancel the buoyancy of the closed box when traveling underwater, making it inconvenient for transportation, maintenance, and inspection in a narrow space.

機構が複雑となる欠点があった。In order to eliminate the drawbacks of the conventional traveling filth suction device using an electric motor as a drive source, a traveling filth suction device driven by an air drive source has been proposed. However, the conventional waste suction device driven by an air drive source is configured as a four-wheel drive type with a pair of front wheels at the front and a pair of rear wheels at the rear, and is driven by the rear wheels while being steered by the front wheels. However, the drawback was that the drive and steering operation mechanisms were complicated.
