Abstract
The utility model belongs to a lifesaving appliance used when a swimmer is drowned or in danger to need rescue of others in the process of swimming. The device for calling help in swimming is composed of a control device and a floating mark indicating device. The control device and the floating mark indicating device are connected into integration by the sucking of a permanent magnet. When the warning isn't needed, a control circuit doesn't work and the warning signal isn't sent out. When the swimmer goes into water, the device for calling help in swimming is worn on the head like wearing a swimming hat. When the swimmer is drowned and in danger to need rescue of others, the swimmer only needs to pick off the floating mark indicating device by hand and the floating mark indicating device can float on the water. Then the floating mark indicating device ticks the warning signal and simultaneously sends out the red blinking light to indicate to the position of the target needing rescue of others.
Description
The utility model belongs to the swimmer to be taken place to drown or get into danger when needing others to rescue in swimming, can send a kind of lifesaving appliance (hereinafter to be referred as rescue beacon) that ensures life security of light and audible alarm.
Up to the present, people also do not have a kind of portable automatic calling for help device in when swimming, in case take place when drowned or in danger, majority are often dead owing to can not get in time rescuing.According to incompletely statistics, annual the swimming season reaches more than hundreds of people because of the untimely and dead number of drowned rescue in China.
The purpose of this utility model provides a kind ofly when drowned or in danger, can send the lifesaving appliance of alerting signal automatically in swimming.Rescue beacon is formed (seeing accompanying drawing 1) by controller and buoy indicating device two parts.The swimmer is worn over rescue beacon on the head as wearing bathing cap when descending water, and at ordinary times, controller and buoy indicating device connect as one by the suction of permanent magnet.When generation is drowned or in danger, the swimmer only needs the buoy indicating device on the head is taken, and the buoy indicating device will swim on the water surface, send " drip ..., drip ... " sound report to the police, send red blinking light simultaneously, the position at target place is rescued in indication.People can rescue in time according to alarm sound of being heard and the indicating target of seeing, ensure the swimming purpose of safety thereby reached.
Controller is a leak free oblong box body.In controller inside control circuit, power supply and permanent magnet are housed, wherein control circuit is used for the control warning and sends light; Power supply is used to provide the energy of control circuit; Permanent magnet is used for being connected and controlling with the buoy indicating device break-make of reed switch contact.
Buoy indicating device (1) is the red transparent spheroid of a garden shape, and wherein the sealing of the spheroid first half is so that floating.Two 2.5 volts bulb (2) is equipped with in the inside, makes luminous indication usefulness, the top dress piezoelectric ceramic piece (3) of spheroid, and the ceramic plate top is for being total to toot chamber (4), to enlarge the loudness of sound.Magnet (6) adhesive on long by 30 * wide 15 millimeters armature (5) and the controller is installed by cylinder at the lower part of spheroid.In remaining space of lower part spheroid, the be intertwined and connected flex lead of buoy indicating device, about 1 meter of the length of flex lead.
In the junction of controller (7) and buoy indicating device (1), registration mast and knock hole (8) are housed respectively, match with permanent magnet on armature on the assurance buoy indicating device and the controller, reach enough the suction-combining forces.
Control circuit is formed (seeing accompanying drawing 2) by five parts.(1) automatic switching circuit is made up of dry-reed tube GK and permanent magnet, and dry-reed tube places the below of permanent magnet, makes the contacting of dry-reed tube by permanent magnet magnetic force; (2) free running multivibrator is made up of BG1,2, R1～R4, C2～C3; (3) amplifier section is made up of BG3, R5; (4) audio alarm circuit is made up of BG4, R6～R7, C5, coil L1, L2, L3 and piezoelectric ceramic piece; (5) filter circuit is made up of R8, C1, C6.
When not needing to report to the police; the permanent magnet on the buoy indicating device controlled device holds firmly, this moment the permanent magnet magnetic force line mainly by the armature on the buoy indicating device, more weak magnetic line of force can not make dry-reed tube GK contacting; so entire circuit do not work, consumed power not yet.
When needs are reported to the police; the buoy indicating device is taken; armature is also taken off with the buoy indicating device; at this moment the magnetic line of force of magnet will mainly pass through dry-reed tube, the contact adhesive in the dry-reed tube is connected, control circuit commences work without delay; astable circuit promptly produces the oscillator signal in about two weeks of per second; BG3 also is in conducting repeatedly, carries the state that ends, and is installed in the indicator lamp in the buoy indicating device, and is glittering immediately by the connection meeting of flex lead.In the circuit energized, the audio frequency oscillator of being made up of BG4 and voltage transformer B also sends audio voltage, drives piezoelectric ceramic piece and sends alarm sound.Because the variation voltage of astable circuit, deliver to the base stage of BG4 through R6, C4, so the tone of controlled audio frequency oscillator is also along with the change of generating period.
In a single day the buoy indicating device is taken, alarm sound will continue after the drowning person is rescued, buoy indicating device and controller to be reconnected incessantly.If the drowning person is not rescued always, till alarm sound will last till always that the power supply in the controller exhausts.
This rescue beacon basic mechanical design feature:
15～20 meters of warning efficient ranges
Stream time 2 hours
Weight 230 grams
Claims (3)
1, a kind of swimming rescue beacon in danger that can send the sound and light alarm signal, it is characterized in that forming by buoy indicating device and controller two parts, armature and permanent magnet are housed respectively on buoy indicating device and controller, both rely on armature to be connected with permanent magnet, utilize the clutch of armature and permanent magnet simultaneously, control makes contacting or disconnection in the dry-reed tube by the magnetic-field intensity of dry-reed tube, realizes automatic switch.
2, swimming according to claim 1 rescue beacon in danger, it is characterized in that the buoy indicating device is a leak free cavity, signal lamp and the light of being made up of piezoelectric ceramic piece, acoustic alarm device are equipped with in inside, when its with after controller separates, can swim on the water surface all the time.
3, swimming according to claim 1 rescue beacon in danger is characterized in that controller is the leak free inner chamber that control circuit, magnet, dry-reed tube and battery are equipped with in a inside.
