DEVICE FOR SIGNALING ON HUMAN IADENING ABOUT A FLOATING OBJECT

The utility model relates to search and rescue equipment in water and can be used to instantly signal an accident when a person falls overboard a floating object.

A device is known by which an alarm can be made about a person being on water. The device includes a base craft, on which there is a ship radio with an omnidirectional antenna mounted on a mast for receiving an alarm from a distressed person, further comprises a small rescue craft with a manual receiver and direction finding device, a manual receiver and direction finding device on the base boat and a radio identifier mounted on the body of a person in distress, while the radio identifier is connected over the air with an omnidirectional antenna and handheld direction finders How on

the base vessel and the small craft, see application RU No. 93007485 of 05/02/93 for class B63C9 / 20.

The disadvantage of this technical solution is its complexity; at the same time, such a complex device as a radio transmitter must be fixed on the human body, requiring a sufficiently powerful power source. Its reliability is very doubtful in view of the possibility of failure of the radio transmitter both during mechanical damage when a person falls overboard and as a result of being in water.

It is also known a signal device containing a personal transmitter that generates infrared radiation arriving at the receiver, which triggers an alarm when signals are not received from the transmitter, see DE 19638017.

The disadvantage of this device is its complexity and high power consumption; in addition, the emitted infrared signal can only be received within line of sight, which reduces the reliability of the device.

Also known is a device for signaling a person falling overboard a floating object, comprising a signaling organ; the device uses a means of generating electromagnetic waves in

as a result of exposure to the piezoelectric material, thereby reducing energy costs, see JP 10105856.

This technical solution is taken as a prototype of this utility model.

It eliminates the need for a battery of electrical power to the device, mounted on the human body and emitting electromagnetic waves.

However, this device is quite complicated, because it requires, as described above analogues, the presence of a transceiver complex; in addition, the reliability of the device is very doubtful, since the respiratory force of a person is used to generate electricity, and when it falls overboard a floating object, various respiratory cycle disorders are possible.

The basis of this utility model is the solution to the problem of increasing the reliability of the device and simplifying its design.

According to a utility model, this problem is solved due to the fact that in the device for signaling a person falling overboard a floating object containing a signaling organ, an electrical circuit connected to the signaling organ is installed around the perimeter of the floating part of the floating object, while a magnetic source is mounted on the human body fields, in particular, a permanent magnet.

The applicant has not identified technical solutions that are identical to the claimed utility model, which allows us to conclude that it meets the criterion of "novelty.

The essence of the utility model is illustrated by drawings, which depict:

in FIG. 1 - floating object, side view;

figure 2 - electrical diagram of the device.

A device for signaling a person falling overboard a floating object 1 includes an electrical circuit 2, which is fortified around the perimeter of its surface part. In a specific example, the electric circuit is closed through an electromagnetic oscillation amplifier 3, from which the signal is supplied to the signaling organ 4; in this example, it is the source of an acoustic alarm. On the human body, in particular, of each crew member and passengers, a magnetic field source is fixed, in particular, a permanent magnet (not shown conditionally not shown in the drawings). Other emergency means may also be included, for example, devices for automatically discharging individual life-saving appliances into the water, in particular, a life buoy with its detection elements, may be activated

When a person equipped with a permanent magnet falls overboard a floating vessel when the magnetic field crosses a permanent

the magnet of the plane of the plane of the electrical circuit 2 in the latter, electromagnetic oscillations are induced, which are amplified by the amplifier 3. From the output of the amplifier 3, the signal is sent to the signaling organ 4, and a siren is turned on, which signals a person falling overboard a floating object. In this case, the alarm is activated earlier than the moment when a person falls into the water, since the electrical circuit 2 is located above the waterline. An individual life-saving tool is thrown overboard, almost synchronously with the fall of a person, so it is in close proximity to the place of the fall.

The device is very simple and reliable in operation, because complex transmitter-receiver system is eliminated; only one element is fixed on the human body - a permanent magnet, which does not require any power and retains its properties in almost any environment.

A device for signaling a person falling overboard a floating object is manufactured in the factory using conventional equipment and known materials, which determines, according to the applicant, his compliance with the criterion of “industrial applicability.
