摘要:
A bilge management and control system for a vessel having a full port through-transom threaded pipe fitting located near the lowest point of the interior of a vessel and ending in a flange mounted against the exterior transom wall, with the means for sealing the interior area of the transom from both sides, with hose barb to male plug adapters (or garden hose adapters) and/or solid threaded plugs threaded into one or both ends of the threaded through-transom pipe, at the entry point and at the exit terminus, such that substances may be prevented from entering a bilge, may be introduced into a bilge and/or forward compartments of a vessel, retained and controlled within a bilge and/or forward compartments of a vessel, or directed out of a bilge and/or forward compartments of a vessel by gravity flow, differential pressure or other mechanical means when the solid threaded plugs at one or both ends are removed or back-threaded to unseal the pipe wall's opposing ingress and egress portholes, if they are present, thus allowing ultimate management and control of the contents of a bilge.

A bilge drainage system for a boat having a through-transom drainage passageway has a through-transom pipe connected to an externally-mounted flange and connected internally to a manually or electronically operated stopcock located near the bottom of the bilge such that the stopcock may be opened, and bilge water drained to the sea, when the boat is traveling through the water on a plane.

An automatically sealing boat draining device to be mounted in a hole passing through the transom of a boat, includes: a cylindrical housing with a drain hole; a ball valve assembly mounted within and removable from the drain hole; and a plug for sealing the drain hole. The ball valve assembly includes a ball, a sealing ball seat component, and a flow through ball seat component that are held within the drain hole by a retaining ring. A flow of water from the outer end toward the inner end of the drain hole causes the ball to seat in the sealing seat component and seal the drain hole. A flow of water from the inner end toward the outer end of the drain hole causes the ball to seat in the ball flow though seat component and permit the flow of water through the drain hole.

Remote-controlled equipment (1) with the ability to move through the inside of a pipeline or other confined cylindrical volumes, pulling an umbilical (10) and carrying accessories. It consists basically of a body (2) and a through-bar (8) which are equipped with heads (3, 4, 5). Said heads are able to be fixed to the inner wall of the pipeline or released therefrom alternately by means of manual or automatic commands. The vehicle (1) has various safety devices to prevent it becoming caught inside the pipeline in abnormal situations. The invention (1) makes it possible to take tools or materials to a remote point inside the pipeline in order to carry out diverse operations.

A method and apparatus is disclosed for permitting the passage of conduits through the hull of a boat without the creation of additional holes. A conduit-accommodating passageway is defined through the boat's scupper which bypasses the check valve that is associated with the scupper to prevent backflow. An annular body having a radially-extending conduit-accommodating passage communicating between its O.D. and its I.D. is positioned with respect to the scupper so that the fluid passing through the scupper and check valve passes through the generally annular body's I.D. while conduit passing through the radially-extending passage passes through the scupper but bypasses the check valve.
摘要:
A drain plug system for a boat which has a sleeve in the drain opening and an expandable drain plug to be disposed in the sleeve. A retainer is connected to the drain plug. The retainer is disposed within the sleeve and has ends which engage the inner side of the sleeve when the drain plug is contracted so that the drain plug is prevented from being lost.

A manifold system for supplying water to two or more consumer devices on a marine vessel having a primary consumer and one or more secondary consumers has a primary conduit connectable to the primary consumer, the conduit having an interior cross-sectional area determined by water requirements of the primary consumer. A manifold has a threaded inlet fitting, a primary outlet fitting dimensioned to be connectable to the conduit, and a plurality of secondary outlet fittings connectable to secondary conduits for secondary consumers. The inlet and secondary outlet fittings of the manifold have cross-sectional areas determined by dimensions of the primary outlet fitting. A strainer has an inlet connected to a through-hull fitting for receiving and straining incoming raw water and an outlet having a threaded connector for attachment to the manifold inlet fitting, the strainer having a flow capacity determined by the diameter of the strainer outlet. The cross-sectional area of the manifold inlet is larger than the combined cross-sectional areas of the primary outlet fitting and the secondary outlet fittings and is determined by the cross-sectional area of the primary outlet fitting.

Several embodiments of bilge devices for small watercraft that permit the use of small capacity bilge pumps and which ensure that the bilge pumps will not run dry during abrupt maneuvers are disclosed. This result is obtained by using a trap-like device that permits water to accumulate from the bilge but which restricts the escape of the water during abrupt maneuvers
摘要:
A universal marine bilge pump mounting system releasably securable either between spaced parallel stringers or between an inner surface of the hull and a higher support surface spaced above the bilge. A base plate is adapted in size to supportively receive the bilge pump and float switch. An upright support member is connected to, and upwardly extends from, the base plate. A bilge surface engaging member of adjustable overall length includes a contact member connected at a distal end thereof. A proximal end of the bilge surface engaging member is releasably connectable in a first use mode to the upright support member. Two bilge surface engaging members are releasably connectable in a second use mode to, and extending in either direction from, the upper end of the upright support members whereby the base plate is supportable above or against the hull inner surface.
摘要:
The present invention is a drain plug apparatus designed and configured to remain in the drain hole of a conventional pleasure water vessel, regardless of whether the vessel is in or out of the water. This drain plug apparatus includes a body assembly having at least two chambers. One chamber will house a shut-off valve for enabling the boater to open or close the drain plug apparatus. This will render water to escape or prevent entrance to the boat, respectively. A safety assembly is included in the second and each subsequent chamber. The safety assembly will prevent water passage into the water vessel should the user forget to close the drain plug assembly, prior to placing the boat in water.
