More particularly, the present invention relates, preferentially, to a remote-controlled buoy for the retrieval of the mooring cable, to be used referring to different types of vessels (e.g. sailing vessels, motor vessels, etc), and preferably for recreational purposes, in a plurality of environments (e.g. seaside, river, lake, etc in which the same is used). The present invention also relates to a process for the retrieval of said mooring cable by means of the buoy itself.
- vessels e.g. sailing vessels, motor vessels, etc
- a plurality of environments e.g. seaside, river, lake, etc in which the same is used.
- the present invention also relates to a process for the retrieval of said mooring cable by means of the buoy itself.
- the present invention also refers to a process for the installation of the buoy, in association with a fixed sinker to indicate that a mooring place for a vessel is free or occupied.
- said recreational boats are moored keeping the stern of the vessel facing towards the berthing place (for example, a dock), and ensuring the bow by means of a cable connected to a submerged catenary.
- said presence of said floating buoy significantly cooperates in facilitating the operator in the retrieval of the cable.
- said method of mooring has different problems, reason for which it is even forbidden in some touristic seaports. These problems are primarily related to the potential risks of tangling up, during mooring, of the cable (which is in fact floating suspended out of the water to effect of said floating buoy) to propellers, rudders or other mechanical parts of the vessel, thereby causing engines deadlock, blocking of rudders or in any case damage to said mechanical parts of said vessel.
- said cable due to the fact that it is suspended in the fluid, and it is therefore susceptible to more or less large fluctuations, may cause similar accidents of tangling up involving other transiting vessels in the immediate nearby.
- the retrieval of the mooring cable takes place only when the concerned vessel is located closed to the dock (or to another docking point), moment in which the retrieval of said cable is ensured manually or by a suitable means provided with at least one end shaped like a hook (for example, a boat hook), said cable is then caused to slide to the bow of the vessel, hoisting and fixing it at the end of said bow.
- said mooring cable when not used, lies on the sea-bed, the same tends to accumulate bodies present on the sea-bed itself, such as algae, barnacles, mud, thus risking to cause more or less deep injuries to the operator during the manual retrieval of said rope.
- the mooring cable once raised, can damage or otherwise consistently dirty the deck or other parts of the vessel.
- Said risk is a particularly consistent in the case in which the operation is handled by an operator alone or in particularly adverse weather conditions. Likewise, in any case the risk remains that said cable gets entangled to the rudder or propeller of the vessel, in particular in correspondence of the steps of departure or mooring, so causing blockage or in any case damages to the same.
- buoys that are able to sink together with the mooring cable which are connected to, to be dragged down to the sea-bed by the weight of said cable, and the same being connected to a catenary, to be later made to come to the surface only when there is a need for the retrieval of the cable for the purpose of docking.

Description
- The present invention relates to a remote-controlled buoy. More particularly, the present invention relates, preferentially, to a remote-controlled buoy for the retrieval of the mooring cable, to be used referring to different types of vessels (e.g. sailing vessels, motor vessels, etc), and preferably for recreational purposes, in a plurality of environments (e.g. seaside, river, lake, etc in which the same is used). The present invention also relates to a process for the retrieval of said mooring cable by means of the buoy itself.
- On the other hand, the present invention also refers to a process for the installation of the buoy, in association with a fixed sinker to indicate that a mooring place for a vessel is free or occupied.
- Usually, said recreational boats are moored keeping the stern of the vessel facing towards the berthing place (for example, a dock), and ensuring the bow by means of a cable connected to a submerged catenary.
- In particular, with reference to said recreational vessels, two different methods of mooring are known.
- First of all, it is known to perform an operation of mooring using a mooring cable connected to a floating buoy, said cable being first hoisted by means of a hook or similar, and subsequently secured to the bow edge of the vessel.
- The presence of said floating buoy significantly cooperates in facilitating the operator in the retrieval of the cable. However, said method of mooring has different problems, reason for which it is even forbidden in some touristic seaports. These problems are primarily related to the potential risks of tangling up, during mooring, of the cable (which is in fact floating suspended out of the water to effect of said floating buoy) to propellers, rudders or other mechanical parts of the vessel, thereby causing engines deadlock, blocking of rudders or in any case damage to said mechanical parts of said vessel. Moreover, in case of unfavourable weather conditions, said cable, due to the fact that it is suspended in the fluid, and it is therefore susceptible to more or less large fluctuations, may cause similar accidents of tangling up involving other transiting vessels in the immediate nearby.
- On the other hand, it is also known to make the docking of the vessel by connecting the catenary to one end of a sufficiently long mooring cable, connecting the other end of the same to the quay, so that said cable, when not in use, will deposit in a natural way on the sea-bed, largely avoiding the risk of tangling up of the same with respect to mechanical parts of surrounding vessels.
- In fact, in these cases, the retrieval of the mooring cable takes place only when the concerned vessel is located closed to the dock (or to another docking point), moment in which the retrieval of said cable is ensured manually or by a suitable means provided with at least one end shaped like a hook (for example, a boat hook), said cable is then caused to slide to the bow of the vessel, hoisting and fixing it at the end of said bow.
- However, even with reference to the foregoing method of docking, certain critical profiles are detected.
- In fact, since said mooring cable, when not used, lies on the sea-bed, the same tends to accumulate bodies present on the sea-bed itself, such as algae, barnacles, mud, thus risking to cause more or less deep injuries to the operator during the manual retrieval of said rope.
- For the same reasons, the mooring cable, once raised, can damage or otherwise consistently dirty the deck or other parts of the vessel.
- On the other hand, in the case of an operation which requires essentially long time, there is a significant increase in the risks of collision with other eventual vessels in the nearby, at least until the moment in which said cable is not properly fixed to the bow of the watercraft.
- Said risk is a particularly consistent in the case in which the operation is handled by an operator alone or in particularly adverse weather conditions. Likewise, in any case the risk remains that said cable gets entangled to the rudder or propeller of the vessel, in particular in correspondence of the steps of departure or mooring, so causing blockage or in any case damages to the same.
- A partial solution to the foregoing inconvenient has been provided through the use of buoys that are able to sink together with the mooring cable which are connected to, to be dragged down to the sea-bed by the weight of said cable, and the same being connected to a catenary, to be later made to come to the surface only when there is a need for the retrieval of the cable for the purpose of docking.
- A buoy of this type is disclosed, by way of example, in document No.
FR 2,109,096 A5 Figure 1 herewith attached. - As it can be seen from the above mentioned
Figure 1 of the drawing, the return of said buoy to the surface, after transmission of a specific control signal (for example, by a ultrasonic transmitting/receiving system), is made possible thanks to the fact that said buoy includes in its inner part compressed-air means that allow its return to the surface, with consequent dragging to the surface of the mooring cable which can then be retrieved by the operator to achieve the docking. Buoys presenting structural and functional features similar to the above stated, or systems including the same buoys, are also disclosed in the documents No.DE 3432868 (Figure 2 ) andEP 0502219 A1 (Figure 3 ). - In addition, the document No.
DE 20 2012 007 062 U1 discloses a buoy having compressed-air means to allow to the relative return to the surface, with consequent dragging of the mooring cable, as well as a mechanical system controlling an inflating pump station , placed in water. - An example of realization of the object of
DE 20 2012 007 062 U1 is provided in the functional diagram shown inFigure 4 , herewith attached. Further devices and advantageous systems for the retrieval of a mooring cable of a vessel are, for example, described in the documents No.WO/2009/004446 A2 , No.WO/2008/029198 A2 , No.EP 1314641 A2 ,US 1220825 andDE 3432868 A1 , of prior art. - However, it can be noted that said known buoys still have several inconvenient.
- First of all, since said known buoys have a structure comprising compressed air means in order to make its return to the surface possible, following to a specific command (for example imparted by means of ultrasonic transmitting/receiving systems) it is required that the operator cyclically provides to refill said foresaid compressed air means.
- This inevitably determines, further than being an increase of the operator charges, the need to promptly have, in case of need, suitable means (e.g., a pump), to do said refilling operations.
- At the same time, it is evident that said refilling operations may be especially complex for the operator if done in emergency situations, in low light conditions or in unfavourable weather conditions.
- Moreover, it will be noted as said known buoys mostly require, for their installation, the presence of permanent installations on the quay, with consequences in terms of relatively consistent dimensions and difficulty in case of displacement to docking the place.
- Moreover, the disposition of said fixed installations necessarily requires the implementation of a plurality of essentially complex operations, further requiring the intervention of experienced divers for the installation of submerged components (in particular at the sea-bed level) of the same installation.
- Likewise, any subsequent maintenance interventions on said installations are often complex and with essentially high costs, since they necessarily require the intervention of specialized operators.
- In addition, said known buoys have an essentially complex structure, so difficult in maintenance, difficult to be reproduced on an industrial scale, and having essentially high costs.
- On the other hand, document No.
US 5,007,029 discloses a device for the retrieval of an object lying on the sea-bed (an embodiment schematically illustrated inFigures 5A and5B herewith attached), in which said apparatus includes a buoy, essentially cylindrical, and connected to said object which, in response to an appropriate remotely imparted signal, returns to the surface for hydrostatic thrust, while the unwinding of a belt or the like, connected to the same, takes place (Figure 5A ), until the point in which, by floating on the water surface, the axis of said buoy is in an essentially horizontal position (Figure 5B ); at this point, it is possible to proceed with the retrieval of the object, lying on the sea-bed, by means of winding said belt on the outer surface of said buoy, which performs a function of a non-motorized winder shaft with horizontal axis. - In light of the foregoing, it will be noted that the operations of retrieval of said object lying on the sea-bed, by means of the apparatus disclosed in
US 5,007,029 are essentially complex for the operator. - On the other hand, said device could hardly be conveniently used for the recovery of a mooring cable of a vessel.
- The present invention, starting from the notion the foregoing inconvenient, aims to provide a remedy to the same.
- An object of this invention according to
claim 1 is to provide a remote-controlled buoy, which allows the operator to perform the above said operations of retrieval of the mooring cable, in a safe and easy way even in case he is operating alone and/or in adverse weather conditions and/or in cramped conditions. - In addition, it is an object of the present invention to provide a buoy as mentioned which does not require, for its use, the previous disposition of fixed installations and that, consequently, can be used in different berth conditions (e.g., among fixed or variable pillars, floating pontoons or the like), and thus not only in the case of docking with respect to a quay, or that can be easily transported and relocated.
- It is also an object of the present invention to provide a buoy as indicated which does not require the operator to cyclically perform refilling operations of the same for its operation, so greatly facilitating the same operator, in particular when he has to operate alone and/or in adverse weather conditions and/or in cramped conditions.
- Furthermore, it is an object of the present invention to provide a buoy as specified, which has an essentially simple structure, easy in maintenance, easily reproducible on an industrial scale and with essentially low cost.
- Moreover, it is an object of the present invention to provide a simple and safe procedure for the retrieval of said mooring cable, by means of the buoy as said.
- On the other hand, it is an object of the present invention to provide a procedure for the use of the above specified buoy, in association with a fixed sinker, to indicate that a mooring place for a vessel is free or occupied.
- In the perspective of such aims, the present invention provides a remote-controlled buoy, the essential characteristic of which is the subject of the main claim, while further advantageous characteristics of the invention are described in the
dependent claims 2 to 8. - The
independent claim 9 relates to a procedure for the retrieval of a mooring cable for a vessel by means of said buoy. On the other hand, theindependent claim 10 refers to a procedure for the use of the buoy, in association with a fixed sinker, to indicate that a mooring place for a vessel is free or occupied. - The above claims are to be considered as fully reported here. More particularly, according to the present invention, said remote-controlled buoy including a main body for protection and buoyancy, a rope provided at one end with dismountable connecting means and, at the other end, connected to a winding device, provided on the inside of said main body, is characterized in that it comprises:
- a rotating shaft of said winding device, which is connected to said other end of said rope and cinematically connected to motor means to be rotated;
- automatic stoppage means for said motor means with rope wound on said shaft, so as to prevent, in the rest position, the rotation of said shaft in the direction of unwinding of said rope;
- remote-control means for said motor means that, in an operating position determined by said remote-control means, rotate in the direction of unwinding of said rope.
- The present invention will result with more evidence, by means of the detailed description that follows, with reference to the attached drawing, having exemplary and not limiting character, in which:
