JPH0711497U - Buoy - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a buoy that can be automatically turned on by using the buoy expansion when the buoy is designed to automatically expand when floated. . [Structure] In a buoy in which a deployable float supported by a spring on a floating specimen is bound with a water-soluble tape and the float is expanded by melting the tape when dropped in water,
The magnetic sensitive switch embedded in the floating sample body is controlled by a magnet piece attached to the float.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a buoy that floats on the sea and reports its position.

[0002]

[Prior art]

 Conventionally, buoys that emit light waves or radio waves and report their positions are widely used for various purposes and purposes. As such a buoy, in addition to the stationary type, as shown in Japanese Patent Application No. 5-24053 by the present applicant, a floating type is used that drops near the target and reports the position. The present invention relates to this floating buoy, and in the conventional buoy of this type, the power was manually turned on to start the device before the submersion.

[0003]

[Problems to be solved by the device]

 However, since this type of buoy is intended to be quickly thrown into the target from the ship or to be automatically detached from the hull in the event of a disaster, it is not possible to intervene manually. Not desirable.

The present invention has been made in order to solve such a problem, and attempts to automatically turn on the power by utilizing the function that the float of the buoy automatically expands when it is put into the sea. It is a thing.

[0005]

[Means for Solving the Problems]

 The buoy according to the present invention controls a magnetic sensitive switch embedded in a floating specimen body by a magnet piece attached to a deployable float supported by an elastic material.

[0006]

[Action]

 According to the buoy of the present invention, when the magnetic sensitive switch embedded in the floating specimen body is stored, the magnetic sensitive switch is in the [OFF] state due to the magnet piece attached to the closely-attached float, and the float floats when it is put into water. The magnet pieces are peeled off, the magnetic sensitive switch is set to the [contact] state, and the device power is automatically turned on.

【Example】

 An embodiment in which a radar transponder is used as an electronic device for a floating specimen in a buoy according to the present invention will be described below with reference to the drawings. FIG. 1 is an external view of a buoy according to the present invention when stored, and FIG. 2 is an external view of the buoy during operation. In FIG. 1, reference numeral 1 denotes a floating sample body in which a radar transponder is incorporated. Reference numeral 2 denotes a battery case, which has a weight sufficient to supply electric power to the floating specimen 1 and to obtain a stable standing. Reference numeral 3 is a spring attached to the main body, each supporting four floats 4. Reference numeral 5 is a water-soluble tape that binds the float 4 folded along the battery case. A magnetic sensitive switch 6 is embedded in the floating specimen body 1. Reference numeral 7 denotes a magnet piece attached to the float 4, which is attached at a position in close contact with the magnetic sensitive switch 6. For this reason, the magnetic sensitive switch is in the [OFF] state due to the magnetic force of the magnet piece 7, and the operation of the device is stopped. FIG. 2 shows a state in which the water-soluble tape 5 is dissolved in water and the float 4 is expanded by the spring 3. At this time, since the magnet piece 7 is separated from the magnetic sensitive switch 6, the magnetic sensitive switch 6 is in the [contact] state, and power is supplied to the device.

[0008]

[Effect of device]

 As described above, since the power supply of the buoy of the present invention used in an emergency is automatically turned on at the time of landing, the buoy can be operated quickly and reliably.

[Brief description of drawings]

FIG. 1 is a view showing an external appearance of a buoy of the present invention when stored.

FIG. 2 is a diagram showing an external appearance of the buoy of the present invention during operation.
