Description

 The invention relates to instrumentation, and in particular to the creation of rescue equipment on the water, fasteners for lifebuoys, rafts using signal devices.

 Known signal buoy, containing a device for fastening the buoy in the deck of the vessel, the body of the buoy with a signal system in the form of batteries with a signal device in the form of an electric lamp, a beacon and a siren, an energy-saving device made in the form of a circuit breaker, and an energy control device in the form of contacts output buoy body parallel to the chopper.

 The buoy for a long time may be in storage mode on the deck of the vessel, but at the same time it must be operational at any time. During storage, for various reasons, the signal system may fail (battery discharge, contact oxidation, etc.), so the system is regularly checked by closing the contacts brought to the housing to the monitoring system. (U.S. Patent No. 5,066,256; NKI 441/7 of 11/19/91).

 The buoy is stored in the attachment device directly on the deck of the ship and is affected by sea water under various weather conditions. This leads to oxidation of the contacts and distorts the results of the health check. To prevent oxidation, the contacts are protected by various devices and methods.

 A known signal buoy comprising a device for attaching a buoy to a deck, a cord for attaching a buoy to a rescue vehicle, a buoy body with a signal system in the form of batteries electrically connected to a signal device, an energy saving device made in the form of a magnetically controlled contact (reed switch) in the power supply circuit, and installed in the hull of the buoy, as well as a magnet fixed against it, installed in the device for fastening the buoy to the deck, and a device for monitoring energy resources. (US patent N 4099282, NKI 441/16 from 06/11/78).

 In storage mode, a magnet breaks the electrical circuit of the signal system through a magnetically controlled contact. In the case of application, the buoy is removed from the attachment device, the magnetic field on the magnetically controlled contact is terminated, the electrical circuit of the signal system closes and the signal device starts emitting a signal to determine the location of the buoy.

 A known method of controlling buoy energy, comprising periodically turning on the signal system with a magnetically controlled contact by closing the electrical power circuit of the signal device and evaluating the power of the emitted signal.

 The closure of the electrical power circuit is accomplished by closing the contacts output to the buoy body parallel to the breaker based on the magnetically controlled contact. The power of the signal emitted by the signal device determines the state of the power supply system.

 However, the oxidation of contacts does not guarantee the reliability of energy control. Energy control by removing the buoy from the mounting device does not guarantee against unauthorized access.

 In order to simplify the design and increase the reliability of the buoy, a device for fastening the buoy to the deck is installed relative to the buoy body with a gap at the location of a normally closed magnetically controlled contact and a magnet for placing a plate of soft magnetic material in this gap.

 This eliminates the conclusion of additional contacts on the buoy body, thereby increasing its tightness.

 In order to increase the reliability of control of the energy resources of the signal buoy, the power circuit is closed by introducing into the space between the magnet and the magnetically controlled contact of the magnetic screen in the form of plates of soft magnetic material.

 The introduction of a magnetic screen into the gap between the magnetically controlled contact and the magnet closes the magneto-magnetic lines of the magnet on the plastic and closes the contacts directly of the power supply system of the signal system, thereby increasing the reliability of energy control.

 In FIG. 1 and FIG. 2 shows a signal buoy. In FIG. 3 shows an electrical diagram of a signal buoy.

 The buoy consists of a housing 1, power batteries 2, a signal device in the form of an electric lamp 3, a device for mounting the buoy in the form of an arm 4, sequentially included in the power circuit of the signal system 5 of a magnetically controlled contact in the form of a reed switch 6, containing a normally closed contact 7 and a normally open contact 8 , a magnet 9 and a gap 10 for placing a plate of soft magnetic material 11, a cord attaching the buoy to the rescue vehicle 12.

 The influence of the magnetic field of magnet 9 on the magnetically controlled contact 6 leads to the opening of the normally closed contact 7 and the opening of the power circuit of the signal system 5. When a screen in the form of a plate of magnetically soft material 11 is inserted into the gap 10 between the magnetically controlled contact 6 and the magnet 9, the magnetic field closes on the screen 11 and a normally closed contact 7 closes the power supply circuit of the signal system 5. As a result, the signal device in the form of an electric lamp 3 emits a signal corresponding in power to its energy resources, and a buoy rivoditsya operational.
