A cleaning swab device and method for cleaning a fluid coupling or connector. The device includes a generally elongate cylindrical tubular swab body, and a channel formed at an end thereof to define at least one cleaning finger for insertion into a housing and/or port of the connector to remove residual fluids, clean and disinfect the connector. The cleaning device optionally further includes a guide stem or plunger configured to extend through the tubular body of the swab, having a plug at one end for sealing debris out of a lumen of the connector during cleaning.

Inertial particle separators having an axially translating or a deformable poppet component are described. The poppet component axially translates to accommodate a wide range of flowrates through the inertial particle separator. In some arrangements, the poppet component is biased by a spring towards a closed or restricted position. The variable flowrate and constriction provided by the poppet maintains a substantially constant pressure drop and separation efficiency during operation across a wide range of flowrates through the separators.

Rotary devices and methods of use thereof are disclosed. The rotary devices may be configured as cleaning apparatuses. A cleaning apparatus may include an elongated tube member with an attachment end portion, a holding end portion, an internal cavity, and a helical slot. The cleaning apparatus may also include a handle with a following pin, the tube member extending through the handle with the following pin extending through helical slot. The cleaning apparatus may further include a guide element, a stop member, a first resilient biasing element of a first stiffness and a second resilient biasing element of a second stiffness positioned within the internal cavity. Longitudinal translation of the handle along the tube member from the holding end portion to the attachment end portion rotates the tube member about the longitudinal axis and resiliently deforms the first and second resiliently deforms the biasing elements.

A fluid flow actuated tool including a housing, a tool and an actuating mechanism. The housing includes a housing interior. The housing interior receives a flow of fluid. The actuating mechanism includes a fluid wheel structure. The fluid wheel structure is connected to the tool. At least a portion of the fluid wheel structure is arranged in the flow of fluid for rotating the fluid wheel structure. The tool is actuated based on rotation of the fluid wheel structure.

A tank cleaning system for cleaning a space. The tank cleaning system can include a trailer having a support base transportable by a vehicle, and an arm movably mounted to the support base for movement relative to the support base. The arm can be operable to extend into the space to perform a cleaning operation inside the space.

There is provided a conduit cleaner including an elongate body. The cleaner includes at least one vane coupled to and extending radially outwards from a longitudinal axis of the elongate body. The at least one vane has a distal end portion shaped to abut against and clean an inner surface of a conduit. According to a second aspect, there is provided a conduit cleaner including an elongate body. The cleaner includes a plurality of turbines rotatably coupled to the elongate body. Each turbine includes at least one vane extending outwards from a longitudinal axis of the elongate body. The vanes have distal end portions shaped to abut against and clean an inner surface of the conduit.

A washing brush to wash a container having a long length. The washing brush includes a handle part, a shaft part connected to the handle part, a sliding part configured to slide along the shaft part, a strip part coupled to the lower end part of the shaft part and lower part of the sliding part, a brush part attached to the outside of the strip part; and a position adjusting part configured to adjust a relative position of the shaft part. The sliding part is pressed to spread the strip part and the spread can be varied by the position adjusting part by adjusting the relative position of the sliding part with respect to the shaft part. A washing brush is provided that can simply and quickly wash a cylindrical container by allowing a washing part to be spread according to the shape of a container.

Inertial particle separators having an axially translating or a deformable poppet component are described. The poppet component axially translates to accommodate a wide range of flowrates through the inertial particle separator. In some arrangements, the poppet component is biased by a spring towards a closed or restricted position. The variable flowrate and constriction provided by the poppet maintains a substantially constant pressure drop and separation efficiency during operation across a wide range of flowrates through the separators.

The weighted deformable cleaning device includes an outer sack sized to receive a weighted sack. The outer sack has an abrasive surface. The weighted sack contains a bead composition having a combination of weighted beads and cushion beads. The weighted beads are made a non-reactive heavy material and are preferably spherical in shape. The cushion beads are smaller in size than the weighted beads and are made from a lightweight material. The number of cushion beads in the weighted sack exceeds the number of the weighted beads such that the cushion beads have a higher volumetric weight in the weighted sack compared to the weighted beads.

The weighted deformable cleaning device deforms to pass through narrow openings of a container, such as a bottle. The added mass from the weighted sack allows for increased frictional cleaning forces when the container is agitated, thereby increasing the cleaning efficiency of the device.

This application provides an intelligent robot for cleaning and mending a net cage and a method of using the intelligent robot, including: a control system, a main body, an attraction module, a motion module, a cleaning module and a mending module. The main body includes a streamlined pressure casing, and a drive mechanism and a water ballast tank which are located in the pressure casing. The attraction module includes electromagnets which are symmetrically provided at a bottom of the pressure casing. The motion module includes first and second motion mechanisms which are symmetrically provided at opposite sides of the pressure casing. A traveling path of the first motion mechanisms is perpendicular to a traveling path of the second motion mechanisms. The intelligent robot achieves cleaning and mending for both sides of the net cage, and is simple to operate, safe, high-efficient, economical and convenient.
