The present invention relates to marine buoys and, in particular, to an improved submersible mooring buoy.
Mooring systems are common marine floating devices and accessories and are often used to moor a watercraft in circumstances where docks are unavailable and/or the water in proximity of the desired mooring location is too shallow for the watercraft to safely navigate.
A conventional mooring system is shown in
The floating top portion of the mooring buoy and the pickup buoy each advertises the location of valuable items to steal and resell without the perpetrator even having to break and enter. Therefore there is a need for a submersible buoy that may be hidden from sight when not in use, thus protecting it and its components from theft.
In addition to the risk of theft, when used in lakes and other bodies of fresh water in cold weather climates, traditional buoys must be removed from the water before these water bodies freeze, in order to prevent loss or damage. This typically occurs in late fall, when water temperatures begin to dip toward freezing, and early spring, when water temperatures begin to rise above freezing. These removals and placements often require diving to the bottom of the body of water to free the anchor in the fall and to set the anchor in the spring. As this is the case, boat owners often need to pay a diver to perform this task each year. Accordingly, rather than removing and replacing the buoy in the fall and spring, respectively, there is a need for a submersible buoy that may be submerged during winter months and floated to the surface once the body of water is free of ice.
Buoys may also act as obstructions to watercraft. Being able to submerge such buoys so that they are not in the way when not in use is another advantage of a submersible buoy. Finally, buoys often mark the location of lobster traps, crab pots, or other devices for catching seafood. Again, such buoys advertise the location of easily stolen seafood and equipment.
Some attempts have been made to design submersible buoys, but each has substantial drawbacks. U.S. Pat. No. 2,546,956 to Yeomans, for example, discloses a submersible buoy. The submersible buoy disclosed therein will sink with the bleeding of air through an opening or rise with a supply of compressed air. Unfortunately, the compressed air is supplied from shore mounted compressors through hose lines. The buoy must therefore be tethered through hose lines. This makes the apparatus not only unwieldy, but likely traceable or otherwise locationally identifiable even when submerged.
International Application No. PCT/AU98/00227 also discloses a submersible and retrievable buoy. This buoy includes a length of rope wound around a spool-shaped body, with one end of the length affixed to the body and one end affixed to an anchor of sorts, such as a crab pot. A free portion of the rope is tied or otherwise securely fastened to a rope shackle pin. When the body is submerged, the rope shackle pin is retained between jaws disposed on the buoy body. When the body is retrievable at the surface of the water, the rope shackle pin is released from the jaws. The release of the pin from the jaws allows the rope wound around the buoy body to unravel so that the buoy body may float to the surface. The retention of the pin in the jaws does not allow this unraveling so that the rope remains wound around the body and close to the anchor. The buoy includes a signal receiver configured to receive a remotely transmitted signal containing information about when the rope release apparatus is desired to be actuated. The signal can be initiated by either a controller or by a timer. Although this buoy represents a significant improvement over other prior art, it relies upon mechanical components that are prone to malfunctioning and failure, especially in environments in which ice and other contaminants are allowed to build upon the rope.
The present invention is a submersible buoy, an inflation control system for submersible buoys and a submersible buoy kit.
In its most basic form, the submersible buoy comprises a substantially flexible inflatable body defining a space filled with a gas, such as air, at a desired pressure. An inflation control system is disposed within the space within the inflatable body. The inflation control system includes a gas compressor in fluid communication with a pressure vessel, a battery electrically connected to the gas compressor such that the battery powers the gas compressor, and a controller in electronic communication with the gas compressor such that the controller controls the operations of the gas compressor.
The body of the submersible buoy is manufactured from a flexible material, such as vinyl. The body is similar in all respects to inflatable buoys sold by manufacturers such as Taylor Made, Gladiator, Turtlepac, and others. The body may be of any size or shape, although a substantially spherical buoy having a twenty inch diameter is preferred. The preferred buoy is not perfectly spherical because it includes at least a mooring end for attaching a line to the buoy, that includes attachment means such as a loop, and may include some flattened areas, such as an attachment panel, which a true sphere would not include. The pressure vessel in fluid communication with the gas compressor of the inflation control system is preferably integrated into the gas compressor and is capable of generating approximately 40 PSI of suction pressure. The pressure vessel may be, for example, a pneumatic cylinder. The gas compressor is operable to compress the gas from the space into the pressure vessel when the buoy is to be submerged and to release gas from the pressure vessel when the buoy is to be returned to the surface. The space within the body of the buoy is a closed system and, by compressing gas into the pressure vessel, the pressure exerted by the gas on the inside walls of the body is decreased, causing the buoy to lose buoyancy and sink. Releasing that same gas causes the pressure exerted by the gas on the inside walls of the body to increase, causing the buoy to gain buoyancy and rise to the surface. The operation of the buoy is therefore founded on the displacement of air volume, which changes the density of the space within the body of the buoy. When the preferred buoy is fully buoyant, the space is filled with air. When the preferred buoy is fully submerged, almost all of the air is drawn into the pressure vessel so that the volume of air remaining is very low.
The battery powers both the release of gas from the pressure vessel of the gas compressor into the space and the compression of the gas from the space by the gas compressor into the pressure vessel. Preferred embodiments of the buoy include a photovoltaic panel or cell disposed on the outside of the body that feeds energy into the battery, or other electrical storage device, when the buoy is floating and exposed to sunlight. Alternatively, in some embodiments, at least the exposed end of the body is transparent or translucent and the photovoltaic panel or cell is disposed within the space. The light is able to come through the body to supply the photovoltaic panel. This embodiment may be preferable so as to protect the photovoltaic panel from the elements. Such embodiments where at least the exposed end of the body is transparent or translucent may also include an indicator light that is visible from outside of the body of the buoy. This indicator light may act as a beacon to aid in locating the buoy at night.
In some embodiments, the body of the submersible buoy also includes an attachment panel for attaching the inflation control system to the buoy within the space. This panel must be airtight and watertight sealable, even considering that the buoy will deform as gas is removed from the space and stored within the pressure vessel and again as the gas is released back in to the space.
It is preferred that the controller be remotely operable by a remote control. The remote control may be a dedicated handheld device that is software programmed for communication with the controller. Alternatively, the remote control may be another device, such as a phone or computer, where software has been downloaded onto the device so that it may act in the capacity of a remote control for this purpose.
In some embodiments, however, the controller may also or instead be controllable by a user interface disposed on the body and/or on the controller itself. The user interface may be included on the attachment panel, for example. It is preferred that the controller include GPS capabilities so that the location of the buoy may be determined even when the buoy is submerged. Alternatively, the buoy may include a GPS-capable device separate from the controller.
In its most basic form, the submersible buoy kit of the present invention includes the submersible buoy of the present invention, an anchor, and a flexible line connecting the buoy and the anchor. The flexible line may be any rope, chain, or line commonly used for such purposes in the art. The anchor may be any heavy device that is attachable to the flexible line and will remain relatively stationary when settled on the seabed. The kit may also include a seafood trap attachable to the buoy, the anchor, or the flexible line. The seafood trap may be a lobster pot, a crab pot, a fish net or trap, or any other type of trap commonly used in the art of catching and trapping seafood.
The submersible buoy kit may also include a dedicated handheld remote control. Alternatively, the submersible buoy kit may include downloadable software that, when in installed on a data processing device, such as a phone or computer, will cause that device to act as a remote control for the controller of the submersible buoy. This downloadable software may be made available in the kit in a physical form, such as a CD, or may be downloadable from the internet.
These aspects of the present invention are not meant to be exclusive and other features, aspects, and advantages of the present invention will be readily apparent to those of ordinary skill in the art when read in conjunction with the following description and accompanying drawings.
Referring first to
Body 12 is a manufactured from a flexible material, such as vinyl. Body 12 is shown with a traditional round buoy shape, but it is understood that the shape of body 12 may be any shape. In addition, body 12 may be constructed of any materials commonly used in the art of buoy manufacturing, such as vinyl, plastic, or rubber. Importantly, the material out of which buoy 10 is constructed should be able to withstand the deformation that may occur when gas is removed from space 17 into the pressure vessel 23 of the gas compressor 22. Although the body 12 may be of any size or shape, a substantially spherical buoy 10 having a diameter of between eight and thirty six inches is preferred.
Mooring end 13 is preferably a reinforced molded end unit manufactured of a material that will withstand the forces exerted on the buoy 10 by the mooring line (shown in
Exposed end 15 is disposed at the opposite end from the mooring end 13 and will be exposed above the surface of the water when buoy 10 is fully inflated. In the embodiment of
Inflation control system 11 controls the pressure of the gas within space 17 defined by the body 12. The inflation control system 11 includes a gas compressor 22 in fluid communication with a pressure vessel 23. Gas compressor 22 preferably also includes an integral gas valve 27 (see
The gas compressor 22 is operable to compress gas from the space 17 into the pressure vessel 23 when the buoy 10 is to be submerged and to release gas from the pressure vessel 23 when the buoy 10 is to be released to the surface. This latter function of releasing gas from pressure vessel 23 is achieved through opening valve 27, which is controlled by controller 26. The space 17 within body 12 of the buoy 10 is a closed system and, by compressing gas into the pressure vessel 23, the pressure exerted by the gas on the inside walls of the body 12 is decreased, causing the buoy 10 to lose buoyancy and sink. Releasing that same gas causes the pressure exerted by the gas on the inside walls of the body 12 to increase, causing the buoy to gain buoyancy and rise to the surface.
As shown in
The user interface 28 is in electronic communication with controller 26 and provides a user with the capability to program controller 26 from the outside of buoy 10, as explained in more detail below. In the embodiment shown, controller 26 may be programmed from the outside of buoy 10 through user interface 28 disposed on body 12. As discussed herein, it is understood that “inflation/deflation” means the release of compressed air from pressure vessel 23 (shown in
The most simple version of user interface 28 will include controls to inflate or deflate buoy 10, i.e. to release air from pressure vessel 23 or suck air into pressure vessel 23, respectively. More advanced versions of user interface 28 may also include controls for additional programming beyond inflation and/or deflation of buoy 10, such as for the functions as described above. User interface 28 may also include an indication of the location of buoy 10 if controller 26 includes GPS capabilities, an indication of depth of buoy 10, and other controls, settings, or views.
In other embodiments, the user interface 28 is included directly on controller 26, which is programmed to the user's specifications at the factory or through other art recognized means. In other embodiments, a user interface 28 is included both on body 12, as shown, and directly on controller 26, and either may be used for such programming. As such, although controller 26 is depicted within buoy 10 in
In the preferred embodiment, which may or may not also include such a user interface 28 or user interfaces, controller 26 is remotely operable. This remote operation may be through any type of commonly used remote control. The remote control may be a dedicated handheld device that is software programmed in advance for communication with the controller. The remote control may also be another device, such as a smart phone, that is software programmed with software that allows the phone to act as a remote control so that it may control and communicate with controller 26 without a physical tether through wireless technology, such as that marketed under the trademark BLUETOOTH. It is preferable that this communication be capable even when buoy 10 is submersed. The operation of controller 26 may be in real time or preset. It is preferable that controller 26 include GPS capabilities so that the location of buoy 10 may be determined even when buoy 10 is submerged. Alternatively, the buoy 10 may include a GPS-capable device separate from the controller 26.

In the embodiment of
Temperature sensor 37 is shown at mooring end 13. Temperature sensor 37 may be a thermocouple, or any other art recognized device that is capable of measuring the water temperature. Temperature sensor 37 is in electronic communication with controller 26 and provides water temperature information to controller 26. Buoy 10 may be programmed to inflate or deflate depending on the temperature of the water. I.e. in late fall, temperature sensor 37 may detect temperatures nearing freezing, which may cause controller 26 to instruct gas compressor 22 to suck air from space 17 into pressure vessel 23 so that buoy 10 sinks. Alternatively, in the spring, temperature sensor 37 may detect rising temperatures until the water temperature is above freezing, which may cause controller 26 to instruct gas compressor 22 to release air from pressure vessel 23 into space 17 so that buoy 10 rises. Temperature sensor 37 may be any commonly used in the art. One of ordinary skill in the art will recognize that temperature sensor 37 may be disposed differently upon body 12, while maintaining its functionality of water temperature measurement. Any of such embodiments are considered a part of the present invention.
Although the present invention has been described in considerable detail with reference to certain preferred versions thereof, other versions would be readily apparent to those of ordinary skill in the art. Therefore, the spirit and scope of the description should not be limited to the description of the preferred versions contained herein.
