Definitions

  • the invention refers to a device for the detection and warning of anchor anchoring of anchored vessels, and a method for said detection and warning.
  • the object of the invention is focused on a device and a method for detecting anchor anchoring by using a series of components that allow constant monitoring, from the right time, of the separation distance. from the anchor to a ballasting device that maintains the reference of the place where the anchor had been left immediately after a successful maneuver of anchorage. If the device detects the event of gagging due to the increase in separation, the device must warn the crew of the vessel in the form of a sign! acoustic, luminous or tactile, taking into account that this warning message must be transported by means that are particularly unavailable to communications and communications facilities such as salt water in motion.
  • the field of application of the present invention focuses on the field of nautical safety devices, mainly for sports or recreational vessels of less than 25 meters in length, whose activities usually include anchoring in areas poorly prepared for it and at risk of garreo.
  • Garreo can be prevented with very large anchors, but the ideal anchor will not always be available. It would therefore be desirable to be able to have a warning system that alerts the crew of the ship when there is garreo, the development of said warning system being the essential objective of the present invention through the procedure and devices proposed herein.
  • the method and device of the invention is based on measuring the distance of the anchor to a fixed point that we will call “reference”.
  • reference When initially depositing the anchor in the bottom, we will declare that the reference and the anchor are in the same place, so the anchor-reference distance is zero.
  • the anchor and the device are in the reference. Yes There is garreo and we declare that the device is not affected by the forces that do move the ship, we know that the anchor will claw and be separated from the reference, but the device will remain in the reference. We will establish a maximum distance of separation of the anchor and the device. When the anchor-device separation exceeds the maximum distance, the device must initiate a process that concludes with the warning to an occupant of the ship to take emergency measures before the garreo. More specifically, the elements of the device and steps of the detection and warning procedure of the garreo proposed by the invention essentially comprise the following:
  • the submersible body of the device Upon reaching the anchoring point, the submersible body of the device becomes firm to the arganum or to the counterattack or cross of! anchor in the area of the device prepared for it (connect). Both are left to the pendulum, with the buoy-orinque of the device and its end already outside the candlestick. The anchor is released and the buoy-cape and cape are left floating.
  • the chain is finished releasing, the system is already deployed on the seabed, which will be armed in a few minutes. At that time, the linear configuration is as follows: ship, chain, anchor, submersible body of the device, cape of orinque and buoy-orinque.
  • the anchor When the submersible body is assembled by timer action, the anchor is attached to the device (weighted) by a short end of a defined distance (2 or 3 meters). Now the ballast is no longer directly attached to the anchor, as it was until the timer produced the release. If the anchor is separated from the ballast by the effect of the garreo! device (which is supposed to cling to the bottom and the sea or the wind do not separate it from its position, as it does with the ship and, therefore, its anchor) there will come a time when the short end is tense, When tense, This end of defined distance will trigger an insurance on the ballast. While submerged while waiting, the ballast is heavy enough to hold a small float at the bottom.
  • This float could go up and down the cape of orinque, since it is shaped like a hoop or toroid and the cape of orinque crosses it.
  • the piping line is not only firm to the ballast, but just after crossing the small float, the cape is once again imprisoned to the same ballast by the insurance, leaving caught in a loop of the cape. This is the way in which the small float is forced to dive with the ballast.
  • the anchor and the ballast must remain attached for the duration of the anchoring operation (the anchor is lowered and the anchor settles), it cannot be allowed in that interval that the short end pulls the insurance. Therefore, at the point of attachment with the anchor and the ballast, a device prepared for it must be placed.
  • This device consists of three parts: the connector that is always attached to the anchor, the release, which is a jaw or closure attached to the ballast, and the timer, which, after 5 to 15 minutes of the anchoring operation, forces the jaw to stop imprisoning the connector, that is, finally the anchor and the ballast cease to have a link that is not the short end.
  • the simplest and cheapest timer can be a tablet of a compound that is diluted in water, such as an effervescent tablet or a salt tablet;
  • the pad must be large and strong enough for the design of the same and the design of the release or jaw to be compatible and the locking mechanism of the connector works well: the jaw maintains a retention position with a spring that forces it to the release position, but the salt pill opposes this movement until it is diluted and stops opposing. Since the step of having the connector locked to released is an internal action of the device, it is possible that the connector seemed at first sight still attached to the ballast while there was no clamping, but as soon as the anchor moved away a little, it would lead to! connector with separating it from the ballast.
  • the main advantages provided by the proposed device are that it prevents an unattended boat that has anchored under certain conditions suffer damage from being dragged if the conditions change and / or the anchoring maneuver has not been performed to withstand the sea conditions. It is common for all occupants of the ship to sleep without a guard while anchored (more if sailing alone). It is therefore advantageous a device that warns if there is garreo.
  • the alternative solution to this device is GPS.
  • the anchorage point is marked on the GPS and programmed to warn of excessive separation.
  • the operating base of this system has a small error and, in addition, configurable (shortening the short firing end), and does not cause false alarms, unless a fish or shellfish drags the short firing end, something unlikely.
  • the ballasted device is of a size manageable by a person and built to withstand the conditions of use (salt water, dragging along the seabed), so a simple construction is key.
  • Other devices are based on complex electronics. This device does not use electronics in its submerged part and uses simple electronics widely tested in the waterproof non-submersible part. It consumes little battery, since the emission of the warning would be of low power and the detection of the passive transponder the messenger requires pulses of discovery of low power.
  • a version with lower battery consumption is one in which the messenger carries a magnet and, a! reaching the buoy, the magnet acts on a magnetic switch inside the buoy; in this case, no battery would be spent on the discovery pulses of the passive transponder, but the warning transmission could fail if the float does not touch the buoy right in the area prepared for it.
  • the device is not affected by borneo; seen on the ground, a ship that drifts describes circumferences around the anchor.
  • the orinque end of the device remains close to the anchor, so it is more unlikely that the borneo causes interference with it, since, seen in plan, both the submersible and the floating part of the device occupy the center of the circumference.
  • the warning is recommended to be low power VHF and virtually all ships have a receiver for this, the warning can be received in a limited but wide area.
  • the device has the advantage of warning not only to the occupant of the ship that cracks, but to those who are nearby (if they have tuned the radio properly) and that they could be damaged by boarding a windward ship that has lost anchor lift.
  • the buoy attached to the ballast shows where the anchor is with a small error; Therefore, it has the function of orinque, which betrays the position of the anchor and the chain, highly recommended and useful in anchorages to prevent two ships from laying their anchors one on top of the other given that the patterns see the buoy and modify their maneuver .
  • the use of orinque is not encouraged enough and although it is constantly recommended from nautical manuals and official instances, it is not customary yet to use it.
  • the described device for the detection and warning of anchor anchoring of anchored vessels, and procedure for said detection and warning therefore, represent an innovation of structural and constitutive characteristics unknown until now for this purpose, reasons that together with its practical utility, the provide sufficient grounds to obtain the privilege of exclusivity that is requested.
  • Figure number 1 Shows a schematic elevational view of an example of the device for detecting and warning of anchor anchoring of anchored vessels, object of the invention, represented once incorporated into the anchor of a anchored ship, showing in it the main parts and elements that comprise as well as the disposition of the same.

  • the device (1) in question comprises the following basic elements:
  • said elements are defined grouped in; a main body (CP), formed by the set of elements: safe (6), release (5), timer (4) and ballast (7); in a submersible body (CS), formed by the set of elements; main body (CP), trigger (3), connector (2) and messenger (9); and in a repeater (R) formed by the elements: sensor (11) and alarm (12) incorporated in the station (3) with all of which, the "maximum distance" will be the allowed separation between anchor (15) and main body (CP), defined by the manufacturer or the employer, from which we declare that there is garreo.
  • the connector (2) is the link between the submersible body and the anchor of the boat. It can be attached to the anchor at any point, even in the chain, but it is advisable to hook it or knot it to the anchor cross or to the counterattack.
  • the connector is integral with the anchor, so when the anchor moves away from the reference, the connector will move away with it.
  • the connector is related to the main body in two ways: by the trigger and the safety, on the one hand, and by the timer, on the other.
  • the trigger (3) is an element that measures the distance between the connector (2) (which is always attached to the anchor) and the main body. When the connector and the main body are separated more than the maximum distance, the trigger is in charge of acting on the safety and moving from the "armed" situation to the "triggered” situation.
  • the trigger (3) can be manufactured in many ways, from a laser system, Near Fiefd Communicaiion, magnetic, radio, etc., although, preferably, it consists of a simple end or steel cable with measure equal to the maximum distance.
  • the insurance (6) is the device that initiates the warning process through a step that is the "trigger", and by which the messenger starts its function from inactive to active, that is, the device goes from armed to trigger situation, which triggers the messaging event.
  • the funding maneuver is usually not immediate. After depositing the anchor in the bottom and having released chain, a time is left for the anchor to find the place where it sits better, even help with the engine reversed for it. Therefore, the connector (2) must not be released from the main body immediately to allow for a distance of separation by garrea, but this event (positioning) must last for a while until said separation takes place (armed).
  • the mission of the liberator (5) is to disconnect the connector (2) of the main body after a reasonable time regulated by the timer (4) from the deployment event (lowering of the device next to the anchor), after the positioning event (settlement of the anchor) until the arming event. In summary, the liberator maintains the connector and main body supportive until the timer tells the liberator to disengage the connector and allow separation distance between the anchor and the main body.
  • the time defined for the timer (4) depends on the manufacturer or the pattern, and a reasonable interval can range from five minutes to one hour.
  • the timer could be an electrical or mechanical device with a configurable interval. However, this is considered too complex and easily deteriorated or failed. Therefore, the preferred timer device is based on the dissolution rate of a solid in water or soluble element (8), and takes the form of a basic mechanical element with a spring, and which holds the connector firmly to the main body until its stroke is no longer limited by the soluble element (8) that is diluted.
  • the ballast (7) is a simple ballast container that should help the submersible body to drag all its components to the bottom next to the anchor and should help the main body to maintain the position on the reference as best as possible. It can be manufactured with some projection that helps to have traction on the bottom and thus better fulfill its function.
  • the messenger (9) is the physical signal that, moving with the carrier as a means or guide, carries the signal, code, stimulus or action that will be amplified or transformed by the repeater so that the warning reaches the end user properly.
  • the transport activity of! messenger originates from the activation of the insurance and its transition from armed to triggered mode.
  • the messenger (9) is a sonar pulse and the carrier (10) the water or that the messenger is a radio wave optimized for a carrier that is water; however, these are expensive options and their underwater accommodation would lead to early deterioration. Therefore, it is estimated that the simplest way to manufacture the device with great durability and low cost is for the messenger (9) to be a float that travels by floating along a line linked to a buoy, float or plow in the surface, out that would be the carrier.
  • the float must have a warning means for the repeater, which could be the float's own blow with the buoy or, better, a magnet on the float that acts on the buoy; however, preferably, the warning means integrated in the float will be a passive transponder calibrated to less than one meter, which will receive discovery sweeps from the sensor.
  • the sensor (11) of the repeater has the mission of sending the information of the messenger (9) to the end user. It is assumed that the way of transporting information from the messenger is designed to do it underwater. The user will be out of! water, so a transformation of the physical form in which the warning message travels is advisable, since the ways of transporting messages under water, in general, are not suitable for propagation in air, and vice versa.
  • the mission of the sensor in the repeater is to capture the arrival of the messenger.
  • radio waves as a messenger and water as a carrier
  • the preferred implementation does not use complicated submersible radio systems that would hinder the design and have maintenance and durability problems, and use a simple float and a rope, the repeater's mission is to detect the near presence of the messenger, at least between 1cm and 100cm.
  • the preferred implementation of the sensor is a radio module that emits discovery pulses at regular intervals (from home 1 second to every 30 seconds, depending on the decision of the ship's pattern or the manufacturer) to detect the possible presence of! passive transponder installed in the messenger.
  • the installation of a magnet in the float is contemplated, when approaching the station (13) it would activate the sensor (11), in this case a magnetic switch.
  • the sensor detects the presence within a meter of the messenger by impact, magnetism or radio, the alarm will be activated.
  • the alarm (12) is the device that sends the warning triggered by a garret to the end user, and it can be an acoustic, luminous, tactile or electromagnetic warning.
  • the ideal form of reception is through a speaker close to the user.
  • An additional device could be manufactured for this, but it would increase the system costs. Therefore, and since almost all ships have an FM radio and / or VHF installed or can carry a portable VHF, the preferred solution to send the notice to the user is the use of an FM or VHF transmission whose content is selectable by the pattern or the manufacturer (strident sounds, the letter "Y” in morse beeps, which means "I am humming", humming, etc.).
  • the alarm be a simple FM or VHF transmitter (it should hardly have a channel selector, a band selector, a warning sound selector, an emission power selector and a test of drums). It is recommended that the maximum alarm emission power be selectable from 0.1W to 0.9W.
  • the end user would tune his VHF on a channel equal to that of the alarm and if the sensor triggers the warning by the alarm, the warning would sound on the radio of the end user.
