After turning off the float sensor 14, the alarms 15A, 15B, 16, 17, and 23 continue to issue the alarm for a predetermined time (for example 60 seconds). After turning off the float sensor 14, a drainage pump 13 continues to be turned on for a predetermined time (for example, 9 minutes).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inundation warning device for small boats.

[0002]

2. Description of the Related Art Conventionally, a float sensor, an alarm, a bilge pump, and a control device for detecting an inundation state are provided in a boat of a small boat.
The control device turns on an alarm and issues an alarm, and turns on a bilge pump to discharge water in the boat outboard.

In addition, when the float sensor is turned off, the control device turns off the alarm and stops the alarm, and turns off the bilge pump to stop.

[0004]

However, the float sensor may repeatedly turn on and off momentarily even in a state where the water is not inundated due to vibrations of the hull, etc., so that the alarm intermittently issues an alarm each time. And the bilge pump starts and stops intermittently.

[0005] When the float sensor is at the last inundation level to determine whether or not the float sensor is turned on, if the float sensor is turned on for a certain period of time due to rocking of the hull, and the float sensor is turned off immediately after issuing an alarm, the occupant will be instructed. There was a problem that the alarm was stopped before judging what the alarm generated by the alarm was.

Further, since the bilge pump is usually provided at the bottom of the ship, if the float sensor is provided at a higher position than the bilge pump, even if the float sensor does not detect inundation and is turned off, the bilge pump remains at the bottom of the ship. There was a problem that a large amount of bilge water still remained.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional problems, and provides an inundation alarm system for a small boat, which prevents an erroneous alarm, and checks an inundation point and improves the reliability of drainage. The purpose is to do so.

[0008]

In order to solve the above-mentioned problems, the present invention is provided with a float sensor, an alarm device, and a control device for detecting a state of inundation in a ship, wherein the alarm device comprises:
It is an object of the present invention to provide an inundation warning device for small boats, characterized in that when the detection of inundation by turning on the float sensor continues for a certain period of time, the control device is turned on to issue an alarm.

According to the present invention, when the detection of inundation by turning on the float sensor is continued for a predetermined time (for example, 3 seconds), the alarm device issues an alarm. Even if it is repeatedly turned on and off, the problem that the alarm device issues an intermittent alarm and the drainage pump and the bilge pump do not start and stop intermittently can be eliminated, and a false alarm can be prevented.

According to a second aspect of the present invention, after the float sensor is turned off, the control device controls the alarm device to be continuously turned on for a certain period of time.
Since the alarm is activated for a certain period of time (for example, 60 seconds), even if the float sensor is turned off immediately after the alarm is issued due to the swaying of the hull, the alarm is issued before judging what kind of alarm is. This eliminates the problem that the vehicle stops, and allows the user to check the flooded area by listening to the alarm.

According to a third aspect of the present invention, there is provided a drain pump which is turned on almost simultaneously with turning on the alarm and discharges the water in the boat out of the boat. The drain pump is turned on by the control device after the float sensor is turned off. If the float sensor is controlled to be continuously turned on, the drain pump will be continuously turned on for a fixed time (for example, 9 minutes) after the float sensor is turned off. However, the problem that a large amount of bilge water still remains at the bottom of the ship is eliminated, and drainage can be reliably performed to a state close to the sky.

According to a fourth aspect of the present invention, a wireless transmitter is provided in the control device, and is controlled so as to transmit an alarm signal to a predetermined wireless receiver when an alarm device is turned on and / or when a drain pump is turned on. Then, an alarm is transmitted from a radio transmitter on the ship to a predetermined radio receiver (for example, a mobile phone owned by the owner or the manager of the marina), and it is possible to know the abnormality of the ship even if the user is away.

The warning device (15A, 15B, 16, 17, 23) intermittently warns even if the float sensor 14 repeatedly turns on and off momentarily due to vibration of the hull 4 or the like. Or the drain pump 13 is started and stopped intermittently, so that a false alarm can be prevented.

After the float sensor 14 is turned off, the alarms (15A, 15A, 15A, 15
B, 16, 17, and 23) will give an alarm. If the float sensor 14 is at the last inundation level to determine whether or not the float sensor 14 will be turned on, the float sensor 14 is turned on for a predetermined time due to the swing of the hull 4 or the like. Even if the float sensor 14 is turned off after the alarm is issued, the problem that the alarm is stopped before judging what kind of alarm is eliminated,
You will be able to check the flooded area by listening to the alarm.

Further, after the float sensor 14 is turned off,
Since the drain pump 13 is turned on continuously for a certain period of time (for example, 9 minutes), even if the float sensor 14 does not detect inundation and turns off, a large amount of bilge water still remains at the bottom of the ship. Disappears, and the water can be reliably drained to a state close to the sky.

Further, from the onboard radio transmitter 23,
For example, an alarm is transmitted to a mobile phone (wireless receiver) 24 owned by the owner or the manager of the marina, so that an abnormality of the small boat 1 can be known even when the user is away.
