摘要： PROBLEM TO BE SOLVED: To improve the capacity of the thruster of a cleaning machine and to reduce the capacity and required driving power of a driving electric motor. SOLUTION: The thruster 9 for pressing a wall surface of a water channel cleaning machine having an electrically driven brush 2 for cleaning, electrically driven wheels 3 and the thruster 9 for pressing the wall surface consists of an electric motor 5 for driving rotary vanes 4 and plural swiveling removal plates 8 in a cylindrical casing 7. These swiveling removal plates 8 are fixed onto the circumference between the outer peripheral surface of the motor 5 and the inner peripheral surface of the cylindrical casing 7 and have an inlet angle α with respect to the axial direction of rotation in the inlet of the swiveling removal plates 8. The outlet angle of the rotary vanes 4 is set zero with respect to the axial direction of rotation in the outlet of the swiveling removal plates 8. The shape of the swiveling removal plates 8 between the inlet and outlet of the swiveling removal plates 8 is formed of smoothly continuing curves. The water flow ejected out of the cylindrical casing 7 is composed of only the axial direction component by removing the swiveling direction component of the flow generated by the rotary vanes 4 at the time of passing the swiveling removal plates 8.

摘要： PROBLEM TO BE SOLVED: To effectively utilize waste nitrogen gas generated by an air-separating device. SOLUTION: This power generating system 10 comprises a gas turbine generating device 16 wherein fuel gas generated by a gasifying furnace 12 forms main fuel; an air separating device 18 to generate an oxidant and nitrogen gas; an oxidant booster 22 to boost the oxidant and feed it to the gasifying furnace; and a nitrogen gas booster 24 to boost nitrogen gas and feed it to the gasifying furnace. Surplus nitrogen gas containing waste nitrogen gas generated at the regenerating process of the air separating device 18 is boosted and the boosted waste nitrogen gas is fed to at least either a gland part 22a of the oxidant booster 22 or a gland part 24a of the nitrogen gas booster 24.

摘要： PROBLEM TO BE SOLVED: To enhance the efficiency of a water-wheel by providing, on the upper wall surface inside a housing, a return plate by which the water discharged from Pelton buckets hits the upper wall surface for preventing it from flowing to the central side of the housing, so that it can be prevented that a part of water hitting the inside surface of the housing flows to the central side. SOLUTION: In a vertical shaft Pelton wheel to be installed in a hydraulic power plant or the like, the pressure energy of the water introduced in a casing 1 is converted into velocity energy in a needle valve 2, and the water hits the buckets 3 of the Pelton wheel and provides a rotating torque to the runner. Out of the water left from the Pelton buckets 3, the water discharged upwards flows out along the housing 4; in this case, by providing a return plate 6 to the upper inside surface of the housing 4, part of water flowing on the inner side or the central side is sent back toward the outside by the return plate 6. Thus, the water can be prevented from falling on a runner disc 5, so that the resistance due to this falling water can be eliminated for preventing the reduction in the efficiency of the water-wheel.

摘要： PURPOSE: To save equipment and operating cost significantly by storing a water-tight lid and an arm in a loading part when carrying a pig into a tubular path, then blocking a carrying-in/out port with the water-tight lid at the time of moving the pig back and forth, and suppressing its floatation into the carrying-in/out port, using a guide rail. CONSTITUTION: Two lower lids 6 which open downward and are installed on a pin 5 at the lower part of a sealing member 4 around the ceiling part 4 of a carrying-in/out port 1, are opened downward by their own weight simply by removing a fixing pin 9 on the one end and at the same time, store a pig guide rail 14 which is fastened to the inner side of the lower lids 6 in such a manner that the rail 14 are suspended. Thus a space, into which a pig 09 is carried is secured. After carrying the pig in, a suspended piece 11 is wound up using a suspension wire attached to the suspension piece 11 at the time of opening the lower lids 6. Then the suspension piece is fixed to the ceiling part by the fixing pin 9 and consequently, the guide rail 14 on the inner side spreads in such a manner that it holds the pig 09 by its own weight. Further, if a running water is flown as specified through the tubular path 01, the pig 09 finds its way into the tubular path 01 downstream without being afloat by the pressure of the running water, and the tubular path is cleaned.

摘要： PURPOSE:To clean the interior of a pipe efficiently using an extremely simple and low cost equipment. CONSTITUTION:A propeller 11 which is rotated by a water stream guided by a guide nozzle 8 is provided on the body of a device, then an arm 15 equipped with a brush 14 at the tip is installed on the rotating shaft 11a of the propeller 11 in a freely closing manner, and floating wheels 9, 19 are mounted on the device body. The propeller 11 is rotated by the riding of the device body over a water stream, then the brush 14 comes in contact with the inner surface of a pipe A through the arm 15 to do the cleaning job, and cleaning the intrapipe is performed more efficiently in proportion to a move rapid flow, without requiring a drive mechanism for cleaning. Thus, cleaning the intrapipe efficiently is done with such extremely simple and low cost equipment.
