摘要： A sea creature cleaning robot for an intake tunnel for a nuclear power plant includes a frame, cutter assemblies, and walking wheel assemblies; the frame is used for mounting and fixing cutter mounting seats and crawler wheels; the walking wheel assemblies mounted on the frame enable the entire device to normally walk in a tunnel; the cutter assemblies control the height of cutters by means of hydraulic cylinders to make the cutters contact the inner wall of the tunnel, and the hydraulic cylinders drive the saw-toothed cutters to move back and forth to remove sea creatures attached to the inner wall of the tunnel; the cutter assemblies are uniformly distributed on the frame, so as to ensure full coverage of the cleaning range of the cross section of the tunnel. The robot can clean sea creatures in tunnels in place of manual work to significantly improve the cleaning efficiency.

摘要： A motorized apparatus for use in maintaining a pipe includes at least one drive portion including a body assembly, a plurality of leg assemblies coupled circumferentially around the body assembly, a plurality of drive mechanisms coupled to the plurality of leg assemblies, and a drive portion coupling mechanism. The motorized apparatus also includes at least one maintenance portion including a body, at least one maintenance device coupled to the body, and a maintenance portion coupling mechanism configured to engage the drive portion coupling mechanism. The at least one drive portion is releasably coupled to the at least one maintenance portion by engaging the drive portion coupling mechanism with the maintenance portion coupling mechanism. The drive portion coupling mechanism and the maintenance portion coupling mechanism are each configured to engage another coupling mechanism when the drive portion coupling mechanism and the maintenance portion coupling mechanism are uncoupled from each other.

摘要： A system for use in maintaining a pipe having a sidewall is provided. The system includes a motorized apparatus sized to fit within the pipe and configured to travel along the pipe through an interior cavity. The motorized apparatus includes a plurality of leg assemblies each including a first leg portion, a second leg portion, and a joint rotatably coupling the first leg portion to the second leg portion. A drive mechanism coupled to the joint is configured to interact with the sidewall. The system also includes an actuator assembly configured to independently position each leg assembly relative to a body assembly to adjust a radial position of the joint of the associated leg assembly relative to the body assembly. The system also includes a controller configured to send instructions to the actuator assembly based at least in part on at least one of a dimension of the interior cavity and a desired force on the sidewall.

摘要： A motorized apparatus for use in maintaining a pipe having a sidewall is provided. The motorized apparatus includes a body assembly sized to fit within and to travel along an interior cavity of the pipe. The body assembly includes a first end and a second end and extending along a longitudinal axis. The body assembly also includes a plurality of leg assemblies coupled circumferentially around the body assembly. Each leg assembly includes a telescoping portion, a bias member coupled to the telescoping portion, and a drive mechanism configured to interact with the sidewall as the body assembly travels along the pipe. The body assembly also includes at least one sensor configured to collect data associated with a force between the sidewall and the drive mechanism, and an actuator assembly coupled to each leg assembly and configured to independently actuate each the leg assembly.

摘要： The present invention is directed to a method of cleaning and inspection of drilling mud carrying flow lines, each flow line having an inner surface. The method includes affixing a fitting to the flow line, the fitting having a main flow channel and a branch flow channel extending at an angle from said main flow channel. A first end portion of the fitting can have an attachment that enables connection of the fitting to the flow line at one flow line end portion. A second end portion of the fitting can have one or more doors that can be moved between opened and closed positions, the door or doors providing an opening that is not closed when the doors are in the closed position. A suction line can be connected to the branch flow channel. A cleaning tool can be guided first into the fitting and then into the flow line using a fluid carrying cable. The cleaning tool and jetting fluid can be used to clean drilling mud and debris from the inner surface of the flow line. The jetting fluid can be removed via the branch flow channel using the suction line. The cable can extend through the door opening or openings when the door or doors are in the closed position. A camera can be guided into the flow line using a camera cable wherein the camera cable extends through the door opening or openings. The cleaning tool is preferably too small to fit through the door opening.

摘要： A fluid spraying facility including a fluid circulation pipe and a scraper that can circulate in the pipe in order to push back the fluid present in the pipe as it moves forward, the pipe and the scraper each having a circular section, the pipe having an inner diameter, the scraper having an outer diameter, the outer diameter having a first value. A difference between the inner diameter of the pipe and the first outer diameter value of the scraper is greater than or equal to 100 micrometers, preferably greater than or equal to 200 micrometers.

摘要： An apparatus for cleaning waste collection systems of solid materials. The apparatus is capable of cleaning waste systems in two known ways. First, a pumping method uses normal and injected water flow to suspend the solids in a slurry. A submersible pump moves the slurry from a collection point up to a pressurized container where the water content of the slurry is decanted and reused as injection water while the particulate material settles to the bottom of the pressurized container. Second, a vacuum system may be used to move the slurry from the waste system to the waste container. The vacuum system creates a negative pressure differential, causing material to be pulled through a vacuum tube and into the waste container. When the container becomes substantially full of solid particles, it may be emptied at a dumpsite.

摘要： A method for inspecting a nozzle includes producing a jet from the nozzle, moving the nozzle to cause the jet to approach a stylus of a touch probe, generating a contact signal under a force acting on the stylus, and determining that the jet is appropriate in response to a contact signal received first after the jet has an axis at a distance from the stylus that is equal to or less than a first normal distance calculated from a normal jet shape.

摘要： A pipe cleaner M4 tool comprising an elongated body having 30 degrees arch, a first end and a second end. Further, the first end and the second end have respective sharp edges to facilitate scrapping action. In addition, the elongated body is biased towards a curved shape, and facilitates spring like action, when moved in a clogged component, to aid in cleaning. The pipe cleaner tool is made of Polylactic Acid (PLA) material.

摘要： A multidirectional wheel for traversing a surface is provided that includes a magnet and a plurality of rollers disposed around an outer periphery of each of the hubs of the wheels. The rollers are mounted for rotation in a second axial direction that is perpendicular to a first axial direction of the wheel. The rollers are supported by a plurality of magnetically-inducible brackets attached to the hub. The brackets are optimally sized and shaped to reduce the space between the magnetized materials of the wheel and the surface upon which the wheel travels.
