Description

The invention relates to a boat launching device monitoring arrangement having the features of the preamble of claim 1 and a boat launching device monitoring method having a boat launching device monitoring arrangement.

With regard to the prior art, this is exemplified on the EP 2 817 210 B1 refer to the corresponding launching devices for boats are known by a mothership, such boats, such as dinghy or ready or tender or cruise or lifeboat, deposited by means of a davit crane from the mothership and after use again aboard the mothership be brought.

The US Pat. No. 9,079,640 B1 FIG. 12 depicts a boat launching device monitoring assembly on a lifeboat that may be locatable via at least one or two detachable connections to a parent ship, the links each having a hook pivotally attached thereto. The various sensors are connected to the transmitter and / or controller to give the operator the status of the overall system or individual sensors on the signaling unit during use of the lifeboat.

Furthermore, from the US 4,281,867 a release device is known, which has a hook, which is pivotally mounted below the suspension point of the release device between a pair of plates and has a balanced cam locking structure.

Cruise ships, passenger ships and cargo ships are to be mentioned as mother ships, in which the use of the boat in addition to a pure emergency use as a lifeboat in addition to a transport use as a tender or cruise boat is possible. When used as a tender or cruise dinghy for the carriage of cruise passengers would then take a repeated urination and get back on board, with corresponding problems arise and conditions must be met.

The problems in the prior art are essentially erroneous operations, misjudgments of the current safety situation of the holding or crane assembly, and technical defects that are not recognized.

The triggering systems, in particular the hook arrangements, of suitably equipped boats, such as dinghy or ready or tender or cruise ship or lifeboat, must be able to open in an emergency, especially under load. During suspension and lifting to resume boats for routine maneuvers, such as tenders or maintenance, the function of opening under load may be unintentionally caused due to misuse or technical defects. This usually results in the boat falling down from high altitudes, which is a deadly danger to the crew and must be avoided or avoided.

• - eine unbeabsichtigte, zu frühe Betätigung des Auslösehebels durch menschliches Versagen,
• - ein Anheben bei nicht vollständig geschlossenem Auslösesystem, z.B. wenn der Auslösehebel in halb geöffneter Position ist, was ebenfalls durch menschliches Versagen durch eine Fehleinschätzung geschieht,
• - Fehlfunktionen des Hydrostatik-Schlosses durch eingedrungene Fremdkörper, wie beispielsweise Muscheln oder dergleichen, wobei dieses ein technisches Versagen darstellt,
• - ein Anheben mit nicht korrekt geschlossenem Haken, wobei dies beispielsweise durch Fremdkörper oder fehlende Schmierung im Haken, insbesondere durch mangelnde Wartung oder Fehlbedienung erfolgen könnte,
• - gerissene oder verschlissene Steuerzüge aufgrund technischen Versagens oder mangelnder Wartung
• - verschlissene oder schlecht gewartete Haken, beispielsweise wenn sich eine Kerbe in Haken eingearbeitet hat, kann das Davitauge des Davit-Krans das Boot trotz geöffnetem Auslösesystem anheben, was ebenfalls auf eine mangelnde Wartung zurückzuführen ist.

Examples of causes of these accidents are:

• - inadvertent, too early actuation of the trigger lever by human error,
• a lift when the release system is not fully closed, eg when the release lever is in the half-open position, which is also due to human error due to a misjudgment,
• - Malfunction of the hydrostatic lock due to foreign objects, such as shells or the like, which represents a technical failure,
• a lifting with incorrectly closed hook, which could be done for example by foreign bodies or lack of lubrication in the hook, in particular by lack of maintenance or incorrect operation,
• - Cracked or worn control cables due to technical failure or lack of maintenance
• - worn or poorly serviced hooks, for example, if a notch has worked into hooks, the davit davit's davit can lift the boat despite the tripping system being open, which is also due to a lack of maintenance.

Such accidents are favored by the fact that technical defects are very difficult to detect at the moment of lifting, since many components and system components of the trigger system are not in the field of vision of the helmsman who is inside the boat and presses the release lever, or Davit-Operateurs, who is on the mothership and operates the davit crane.

It is an object of the present invention to provide a boat launching device monitoring arrangement and a boat launching device monitoring method with a boat launching device monitoring arrangement that cope with accidents and dangerous situations when launching and lifting or resuming boats can be effectively prevented.

Decisive condition in this boat launching device monitoring arrangement and the associated method is that all functions can be bridged at any time in an emergency by the intervention of humans and thus in dangerous situations, a release of the boat from the mothership is possible.

This object is achieved with a boat launching device monitoring arrangement according to the main claim and a boat launching device monitoring method with a boat launching device monitoring arrangement according to the independent claim.

The boat launch monitoring arrangement is located on a dinghy or ready or tender or cruise tender or lifeboat. This boat can be arranged on a mothership via at least one or two detachable connections, so that this is left by disconnecting the detachable and also connectable connection / connections from the mothership to the water and / or staggered again by connecting the detachable connection / connections on board of the mothership can be obtained. In this case, this releasing and / or connecting the detachable connection / connections of a arranged within the boat control unit via a trigger lever mechanically, electrically and / or hydraulically. The releasable connection comprises a hook system having a pivotable hook and a pawl or latch and release bolt. For the at least one or two detachable connections a sensor system is provided on the boat side, wherein at least each releasable connection two sensors are provided on the detachable connection and the sensors can detect at least the position, position and / or state of the hook and the pawl or locking and release bolts , Further, in this regard, at least one sensor is provided on the control unit arranged inside the boat, wherein the sensor can detect at least the position, position and / or state of the release lever. The at least three, with a detachable connection, or five, with two detachable connections, sensors are connected to an evaluation electronics and / or control device, wherein the evaluation electronics and / or control device interrogates the sensors. Furthermore, the evaluation electronics and / or control device is connected to at least one signaling unit, so that the status of the entire system or of the individual sensors on the signaling unit can be signaled to at least one operator.

The implementation for the detection takes place with the aid of a monitoring or monitoring system designed according to the invention, in which case accidents are precluded by early checking, recognition and signaling of operating errors and technical errors on or of the triggering system.

The condition or position of the triggering system is monitored by electronic or mechanical sensors. An electronic evaluation unit converts the sensor signals, for example, into light signals on a light signal signaling unit, which clearly indicates to the helmsman, who is in the boat and operates the release lever, and the davit operator, who operates the davit crane on the mother ship, that the Trigger system of releasable connections is in a safe or unsafe position.

The helmsman and davit operator can thus stop lifting the boat and detect and prevent a dangerous situation if the monitoring system indicates an unsafe condition.

Furthermore, the signaling unit can also be designed as a monitor or display or also be part of the driver's cab and its display system.

• - beim Aussetzten des Bootes: der Steuermann betritt das Boot in der Stauposition und schaltet das Überwachungssystem an. Wenn das System eine sichere Stellung anzeigt, wird mit dem Aussetzvorgang begonnen. Falls das System eine unsichere Stellung anzeigt, wird der Aussetzvorgang nicht eingeleitet und eine Fehlersuche durchgeführt,
• - Anheben des Bootes: das Boot schwimmt neben dem Mutterschiff, so dass die Davit-Langaugen in den vorderen und hinteren Haken eingehakt werden, wobei im Anschluss das Boot ca. 1m angehoben wird. Nun schwimmt das Boot nicht mehr und das Hydrostatik-Schloss schließt. In dieser Position oder auch bereits früher, nämlich bereits beim Beginn des Verbindungsvorganges zur Hakenverbindung, wird das Überwachungssystem angeschaltet. Ca. 1 m über der Wasseroberfläche, wobei das Hydrostatikschloss geschlossen sein muss, wird der Systemzustand sowohl von dem Steuermann als auch von dem Davit-Operateur abgelesen. Wenn das System eine sichere Stellung anzeigt, wird der Anhebevorgang weiter fortgeführt. Für den Fall, dass das System eine unsichere Stellung anzeigt, wird der Anhebevorgang nicht fortgeführt, sondern mit der Fehlersuche begonnen und die Fehlerursache gesucht. Durch eine optische Anzeige auf dem Bootsdach sieht auch der Davit-Operateur sofort, dass er den Davit-Kran in diesem Fall nicht weiter ansteuern darf, um das Schiff an Bord des Mutterschiffes zu bringen.

In principle, two scenarios are possible, namely:

• - when the boat is dropped: the helmsman enters the boat in the stowed position and switches on the monitoring system. When the system indicates a safe position, the suspension process begins. If the system indicates an unsafe position, the suspend operation will not be initiated and troubleshooting will be performed.
• - Lifting the boat: the boat floats next to the mothership, so that the davit long eyes are hooked in the front and rear hooks, after which the boat is raised about 1m. Now the boat no longer floats and the hydrostatic lock closes. In this position or even earlier, namely already at the beginning of the connection process to the hook connection, the monitoring system is turned on. Approximately 1 m above the water surface, with the hydrostatic lock being closed, the system status is read by both the helmsman and the davit operator. If the system indicates a safe position, the lifting process continues. In case the system indicates an unsafe position, the lifting operation does not become continued, but started with troubleshooting and searched for the cause of the error. With a visual display on the boat's roof, the davit operator immediately sees that he can not continue to drive the davit crane in order to bring the ship aboard the mothership.

For the sake of completeness, it should be pointed out at this point that a release lever is of course also to be understood as meaning a switch which is actuated if it is at least an electrical system for releasing the detachable connection.

• - elektronisch induktive oder mechanische Messung der Stellung einzelner Komponenten, insbesondere der Sperrklinke, des Haupthakens, des Auslösebolzens, des Auslösehebels sowie des Hydrostatik-Schlosses des Auslösesystems;
• - elektronische Verarbeitung der Messung und automatische Klassifizierung in „sicher“ oder „unsicher“;
• - Darstellung des „sicher“ oder „unsicher“ Zustandes auf einem Display, beispielsweise eines zwei oder drei LEDs aufweisenden Paneels im Boots-Cockpit für den Bediener des Auslösesystems und auf dem Bootsdach, nämlich in Form von wenigstens einer, bevorzugt zwei, besonders bevorzugt drei Dachlaternen, bevorzugt ebenfalls als LED, für den Bediener des Davits-Kran, der das Boot anheben oder absenken soll;
• - Ein-/ Ausschaltfunktion, damit Indikator-Laternen auf Bootsdach nicht mit Navigationslaternen verwechselt werden können.

Further elementary and optional functions of the boat launch facility monitoring arrangement and the boat launch facility monitoring process for a boat launch facility monitoring arrangement may be, in particular:

• - electronically inductive or mechanical measurement of the position of individual components, in particular the pawl, the main hook, the release bolt, the release lever and the hydrostatic lock of the release system;
• - electronic processing of measurement and automatic classification into "safe" or "uncertain";
• Representation of the "safe" or "unsafe" state on a display, for example, a two or three LEDs panel in the boat cockpit for the operator of the triggering system and on the boat roof, namely in the form of at least one, preferably two, more preferably three Roof lanterns, preferably also as LED, for the operator of the davit crane, who should lift or lower the boat;
• - On / Off function, so that indicator lanterns on the boat roof can not be confused with navigation lanterns.

According to the invention, exactly two detachable connections are provided on the dinghy or ready or tender or cruise ship or lifeboat, each detachable connection having exactly three sensors. These three sensors are each arranged on a main hook, a release bolt and a pawl, so that at least their position and / or position, namely open, closed and / or locked, is detected.

The releasable connection may have an additional hook lock, wherein a third sensor is provided on the releasable connection, so that the position, position and / or state of the hook and the pawl or latch and the release bolt can be detected.

In addition, a hydrostatic lock can be provided inside the boat as a barrier for the control unit, so that a release in functional hydrostatic lock is only possible with proper contact of the boat with the water, and wherein at least one sensor on the arranged inside the boat control unit or is provided on the hydrostatic lock, so that the sensor can detect the position and / or position of the hydrostatic lock. In this way, a further safety aspect is given in addition, which allows an absolute release of the detachable connection only with sufficient water contact.

The sensors can be designed as proximity switches or mechanical pressure switches.

The signaling unit may be an optical and / or acoustic indoor display and / or an optical and / or acoustic outdoor display, comprising at least one, two or three state lights, wherein at least the states of the overall system "secured" and "unsecured" or individual signaling signals or can be signaled.
