Abstract

PURPOSE:To obviate any collision or stranding accident, etc., from occurring by stopping a ship making an alarm signal outputting means start its alarm signal output when a radar catches an obstacle, and also outputting a stop control signal in the case where the alarm signal has been outputted continuously beyond the specified limit time. CONSTITUTION:When a radar 14 consisting of a radar scanner 12 and a radar image receiver 13 catches an obstacle, an alarm signal outputting means 11 starts the output of an alarm signal (a), and simultaneously sounds a buzzer 15 built-in a radar image receiver 19, calling a steerman's attention to it. When he remains unnoticed, however, and the alarm signal (a) is continuously outputted beyond the specified limit time, a stop control signal (b) is outputted from a control signal outputting means 17, through which a stop operation means 18 comes to operate a linkage mechanism 20 interlocking with a steering clutch 19 of a propeller machine 1 in consequence, thus a ship is made so as to be automatically stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an emergency stop device for a ship, which is used, for example, to ensure safe navigation of a small ship.

[Prior art] According to a survey by the Maritime Accident Inquiry Agency, there are 600 ship collisions every year.
There are as many as 0 vessels, of which approximately 25% are small vessels. The causes of most of these collisions and groundings are non-compliance with navigational regulations and insufficient lookout, both of which are caused by the actions of ship operators.

2. Description of the Related Art Conventionally, in order to avoid ship collisions, ships have been equipped with collision warning devices that sound a buzzer or the like to notify an emergency situation when a radar detects a dangerous obstacle. If the operator notices a warning from a buzzer, etc., checks the navigational status of the other ship, and determines that there is a risk of collision, take avoidance measures or stop the ship.
This is intended to prevent ship collisions.

[Problem to be Solved by the Invention] However, in the case of the above collision warning system, the operator may be asleep or away from the bridge and may not notice the warning, and this human carelessness may cause the operator to fail to notice the warning. Collision accidents may occur because ship operators fail to take measures to avoid collisions.

As countermeasures to this problem, there is a strong demand for measures that acknowledge the inattention of ship operators, as well as thorough confirmation of caution through training, and strengthened management of fatigue and health.

[Means for Solving the Problems] The present invention aims to solve these inconveniences, and its gist is to provide an alarm signal output means that starts outputting an alarm signal when a radar captures an obstacle. , a control signal output means for outputting a ship stop control signal when the alarm signal is continuously output beyond a set limit time, and an interlocking mechanism interlocked with a control clutch of the propulsion machine; An emergency stop device for a ship is characterized in that it comprises a stop actuation means for actuating a linkage mechanism to stop the ship when a control signal is output.

[Function] When the radar captures an obstacle, the alarm signal output means starts outputting an alarm signal, and if the alarm signal continues to be output beyond the set limit time, the control signal output means initiates ship stop control. A signal is output, and when the ship stop control signal is output, the ship stop actuating means causes a linkage mechanism interlocked with the control clutch of the propulsion machine to stop the ship.

[Example] Figs. 1 to 13 show examples of the present invention, Figs. 1 to 9 show the first embodiment, Fig. 10 shows the second embodiment, and the 11th embodiment.
Figures 1 to 13 show the third embodiment.

In the first embodiment shown in FIGS. 1 to 9, 1 is a propulsion machine, which is composed of an engine 2, a clutch 3, a propeller 4, etc., and an engine control handle 5 is provided with a throttle handle 6 and a clutch handle 7. , the throttle handle 6 is connected to the throttle 8 of the engine 2 via a throttle cable 9, and the clutch handle 7 is connected to the clutch 3 via a clutch cable.

Reference numeral 11 denotes an alarm signal output means, which is connected to the radar μ consisting of a radar scanner and a radar receiver, and the range in which the alarm signal is emitted can be arbitrarily set in advance, and it is possible to prevent obstacles within this range. When detected, the system starts outputting an alarm signal a and sounds a buzzer 5 built into the radar receiver to alert the vessel operator.

`` is a control signal output means, which includes a timer for measuring the duration of the alarm signal a output from the alarm signal output means 11 and calculation settings for setting the limit time for the alarm signal a to be continuously output. and is configured to output a ship stop control signal (a) if the alarm signal (a) is continuously output beyond a preset limit time.

In this case, a whistle, which is a warning means, is connected to the control signal output means light, and the whistle is sounded in response to the above-mentioned ship stop control signal.

The trout is a ship stop actuating means, which has a linkage mechanism connected to a control clutch 4 provided in the clutch 3 of the propulsion machine plate, and causes the linkage mechanism to stop the ship when the ship stop control signal is output. It is configured to include a control section for operating the device.

In this case, the linkage mechanism is equipped with an electric cylinder n, a connecting fitting, a linking cable, etc., and the piston U of the electric cylinder n is connected to one end of the connecting fitting n, and a long hole is formed in the connecting fitting. The cable core powder a of the interconnection cable is connected to a pin portion slidably fitted into the elongated hole 5.

However, in the case of the lever linkage mechanism, the cable core 10a of the clutch cable stirrup is connected to the steering clutch crane, and as the clutch handle 7 moves, the cable core 1)a moves, moving the steering clutch 4 to the forward position AH1 neutral position. N. When moving to the reverse position AS and switching the clutch 3, the cable core 29a of the connecting cable is also connected to the control clutch 4, so the cable core 2!3a will also move as the control clutch 4 moves. In the normal state shown in FIG. 3, the bottle part is located at the center of the elongated hole 2, and therefore, the control clutch 4 is moved to the forward position AH1, neutral position N, and the cable core 10a.
Even if the cable core ff1a of the linking cable holder is moved by being moved to the retreat position AS, the bin portion only moves left and right in the elongated hole portion, and for example, when moving forward in the normal state, it will be in the state shown in FIG. 6.

When the stop control signal S is output from the control signal output means light and the ship enters an emergency stop state, the electric cylinder in the linkage mechanism operates as shown in Fig. 7, and the piston U pushes the connecting metal catfish to the right in the figure. However, the pin is in the neutral position N at the left edge of Chodai 5.
The control clutch is moved to the neutral position N via the cable core a, the clutch 3 is disengaged, and the connecting fitting is further pushed by the electric cylinder.
As shown in the figure, the bottle part is pushed to the retreat position AS, the control clutch 4 is moved to the retreat position AS via the cable core a, the clutch 3 goes into retreat, and the propeller 4 of the propulsion mechanism 1 rotates in the reverse direction. , the electric cylinder operates in reverse, and the connecting fitting is pulled to the left in the figure by the piston.
As shown in the figure, the pin part is moved to the neutral position N by the right edge of the long six-bar, and the control clutch 4 is moved to the neutral position IfN via the cable core 29a, and the clutch 3 is disengaged, and such a stop operation is performed. will be done.

Since this first embodiment has the above-mentioned configuration, when the radar noise detects an obstacle, the alarm signal output means 11 starts outputting the alarm signal a, and at the same time sounds the buzzer etc. built in the radar receiver n to alert the vessel operator. If the warning signal a continues to be output beyond the set limit time without the vessel operator noticing, a stop control signal is output from the control signal output means light. When this ship stop control signal is output, the ship stop actuating means activates the interlocking gear connected to the control clutch 4 of the propulsion machine 1 to stop the ship, and the whistle, which is the warning means, continues to sound. Even if the ship operator does not notice the warning, the ship can be automatically stopped, collisions, running aground, etc. can be avoided, and navigation safety can be ensured.

In addition, in this case, the means for stopping the ship is activated through the linkage mechanism.
Not only does the steering clutch 4 be moved from the forward position to the neutral position to stop the rotation of the propeller 4, but it is further moved to the reverse position to reverse the rotation of the propeller 4, and the ship is finally brought to the neutral position while the vessel is slightly stopped. Since the stopping operation is performed by moving the ship and disengaging the clutch 3, even if the ship is moving forward at high speed and has a large inertia, it can be stopped in a short distance.Moreover, by controlling the movement of the piston of the electric cylinder, it is possible to stop the ship in a short distance. It is also possible to obtain the clutch status, for example, forward, neutral, reverse with half clutch, neutral, reverse,
A neutral ship stopping operation can be obtained, and overloading of the engine 2 can be prevented.

In addition, the battery for starting the engine 2 can be used as a power source for the electric cylinder 2, and manual operation using the engine control handle 5 etc. is given priority over the automatic stop operation using the stop operation means. It is assumed that a circuit is incorporated so that when the power is turned off, the electric cylinder automatically operates and is placed in the normal state shown in FIG. 3 above.

The second embodiment shown in FIG. 10 shows a sideways structure of the linkage machine ellipse,
In this case, the structure is such that an air cylinder i is used in place of the electric cylinder 28a in the first embodiment, and the piston 4 of the air cylinder i is connected to the cable cores 2 and 3a of the linking cable device, and the opposite side of the cable core 28a is Connect the end to the steering clutch 4, while stopping the gas cylinder 4,
It is configured by connecting to an electromagnetic switching valve via a pressure reducing valve, throttle valve, etc.

However, in the case of the lever linkage mechanism powder, the cable core 10a of the clutch cable powder is connected to the steering clutch 4, as in the first implementation rod, so as the steering clutch 4 moves, the cable core 10a of the clutch cable powder is connected to the steering clutch 4 via the gable core core a. In this normal state, the solenoid switching valve is located at the center of the oven, so the air inside the air cylinder only goes in and out through the solenoid switching valve, so the piston moves. has no effect.

When the control signal output means ffJ outputs the stop control signal and enters the emergency stop state, the electromagnetic switching valve is activated.
Gas, such as CO2 gas, enters the air cylinder from the gas cylinder 4 through the electromagnetic switching valve field, pushes and pulls the piston area, operates the control clutch 4 through the link cable field, and engages and disengages the clutch 3. will be done.

It is assumed that the electromagnetic switching valve is appropriately controlled so as not to put strain on the engine 2 or the clutch 3.

In addition, in order to give priority to manual operation using the engine control handle 5, etc. over the above-mentioned automatic stop operation using the stop operation means 4, when the power is turned off, the electromagnetic switching valve automatically becomes demagnetized and switches to the oven center. , located in the normal state shown in FIG. 10 above, and can be manually operated.

The third embodiment shown in FIGS. 11 to 13 shows a separate structure that is a modification of the first embodiment. In this case, an electromagnetic solenoid is attached to the connecting fitting, and the plunger 5 of the electromagnetic solenoid is used to control the pin. It is configured so that its movement can be locked.

However, in the normal state, the electromagnetic solenoid winnow is in a non-operating state, and the same operation as shown in Figs. When this happens, the plunger surface of the electromagnetic solenoid winnow protrudes in the forward-moving layer shown in FIG. 6, locking the bin as shown in FIG. 11, and in this state, the ship is stopped in the same way as shown in FIGS. When the air cylinder reversely operates and the connecting fitting is pulled by the piston 4, the air cylinder changes from the state shown in FIG. 11, which corresponds to FIG. 8 of the first embodiment, to the first state.
The state shown in FIG. 3 is reached, and therefore, compared to the first embodiment in which the state changes from the state shown in FIG. 8 to the state shown in FIG.

Note that the alarm signal output means 11 of the above embodiment. Other configurations may be adopted as appropriate for the configurations of the control signal output means U, the ship stop actuating means, and the linkage mechanism 3.

[Effects of the Invention] As described above, in the present invention, when the radar captures an obstacle, the alarm signal output means starts outputting the alarm signal, and the alarm signal continues to be output beyond the set limit time. In this case, the control signal output means outputs a stop control signal, and when this stop control signal is output, the stop actuation means operates the interlocking mechanism linked to the control clutch of the propulsion machine to stop the ship. Even if the ship is not aware of the warning, the ship can be automatically stopped, collisions, running aground, etc. can be avoided, and navigation safety can be ensured.

As described above, the intended purpose can be fully achieved.
