Description

  The present invention relates to an immersion battery that generates power using seawater or fresh water as an electrolyte, and a life lamp apparatus that lights a life-saving indicator lamp by an electromotive force generated by the immersion battery.

  Conventionally, as a life jacket, as shown in FIG. 6, a life jacket equipped with an immersion battery a such as a seawater battery and an indicator light b such as a light bulb or LED has been proposed. The life jacket c is mounted on an airplane, a ship, or the like in preparation for an emergency. When a passenger or an occupant wears the life jacket and landed, the immersion battery a is immersed in water to generate an electromotive force, and the indicator light b is automatically turned on by the electromotive force. The light of the indicator light b is emitted toward the sky or in all directions, thereby providing a clue to know where the victim is.

  Seawater batteries that generate electricity using water as an electrolyte are used for the above-mentioned life-saving indicator lamps, as well as indicator lights such as marine marker lamps and buoyant lamps. This type of seawater battery uses an anode formed using a relatively low ionization metal such as nickel or copper or an alloy thereof, and a relatively high ionization metal such as magnesium, aluminum or zinc or an alloy thereof. (For example, Patent Document 1), and the life-saving indicator lamp is lit and driven by the electromotive force generated in the seawater battery. The marine beacon lamp and the buoy lamp are driven to be lit by DC power supplied from the secondary battery at night after boosting the electromotive force and charging the secondary battery.

JP-A-8-17446

  However, in the seawater battery described above, gas and ions such as oxygen and hydrogen generated during the electrolysis of water adhere to the electrode part (mainly the anode), so the power generation performance is significantly reduced, and the indicator lamp can be reliably used for a long time. It is difficult to light up. In addition, when this type of seawater battery is used as a power source for a life-saving indicator light, an electromotive force cannot be obtained unless the seawater battery is immersed in water. When placed, the indicator light turns off, which may delay the discovery of the victim. Also, when carrying a life-saving indicator light for emergency use such as mountain climbing or mountain skiing, it is not easy to keep the seawater battery immersed in water in an emergency, so this type of seawater battery is suitable for mountain climbing and mountain skiing. It is not suitable as a power source for life-saving indicator lights.

  The present invention has been made paying attention to the above-mentioned problem, and the power generation performance is not deteriorated due to gas or ions generated during the electrolysis of water, and the indicator lamp can be reliably turned on for a long time. An object of the present invention is to provide an immersion battery and a life lamp capable of obtaining an electromotive force and maintaining the display lamp on without being immersed in water at all times.

  An immersion type battery according to the present invention has an anode and a cathode formed using metals or their alloys having different ionization tendencies, and includes an adsorption member for adsorbing gas or ions generated by electrolysis of water. The at least one electrode and the adsorbing member are wrapped with a water-retainable perforated sheet.

  The immersion type battery according to a preferred aspect of the present invention includes a cylindrical case that constitutes the cathode, an electrode rod that constitutes the anode, and a cap that covers both ends of the cylindrical case. The cap is held so as to penetrate the inside. The cylindrical case or cap has a gap or a hole through which water can enter the inside of the cylindrical case. Inside the cylindrical case, a granular adsorption member for adsorbing gas and ions generated by electrolysis of water is filled around the electrode rod, and the adsorption member is formed by a perforated sheet having water retention capacity. Wrapped.

  In the immersion type battery having the above-described configuration, gas and ions generated during electrolysis of water are adsorbed and removed by the adsorbing member, so that power generation performance does not deteriorate and generation of electromotive force can be reliably maintained for a long time. . In addition, the perforated sheet prevents scattering of the adsorbing member and prevents movement of salt generated at the electrode, thereby preventing a decrease in power generation performance and holding water by water retention. Maintain power generation even if not always immersed in water.

  In the above-described configuration of the present invention, the “anode” is configured using a metal having a relatively low ionization tendency such as copper, nickel, lead, or an alloy thereof. The “cathode” is made of a metal having a relatively high ionization tendency, such as magnesium, aluminum, or zinc, or an alloy thereof. The “adsorbing member” is preferably granular, and for example, activated carbon or barley stone is used. Furthermore, as the “perforated sheet”, it is desirable to use a nonwoven fabric made of porous fibers, and the performance of the immersion battery is not hindered by having water permeability. In addition, since it has water retention, power generation is maintained even if the immersion battery is not always immersed in water.

  A life lamp device according to the present invention includes any one of the above-described immersion batteries, a display lamp that lights continuously or intermittently, and a lighting circuit that turns on the display lamp by an electromotive force generated by the immersion battery. ing.

  In the above-described configuration of the present invention, various types of “indicator lamp” such as an LED, a light bulb, and a xenon discharge tube can be used. In particular, it is desirable to use an LED that emits light with high luminance. For this purpose, a booster circuit may be provided in the lighting circuit. Further, in addition to the LED that lights continuously, a self-flashing type LED may be used. Furthermore, when a xenon discharge tube is used, a booster circuit that boosts the electromotive force generated by the immersion battery in the lighting circuit, a capacitor that stores the charge by inputting the boosted voltage, and the charge stored in the capacitor every certain time A trigger circuit or the like that discharges the current to the xenon discharge tube is provided.

  According to the present invention, the power generation performance does not deteriorate due to gas or ions generated during the electrolysis of water, and the indicator lamp can be reliably turned on for a long time. Moreover, even if it is not immersed in water at all times, an electromotive force is obtained and the lighting of the indicator lamp is maintained, so even if it is not immersed in water for some reason, the indicator lamp does not turn off and the victim's There is no risk of delaying discovery. It can also be used as an emergency life lamp for mountain climbing and mountain skiing.

The caps 4 and 5 are fitted to both ends thereof so that the cylindrical shape is maintained and the openings at both ends are closed. ing. Note that the cylindrical case 2 does not necessarily have a cylindrical shape. In the structure of this embodiment, since the gap 7 is formed along the side edge of the copper plate, water enters the inside of the cylindrical case 2 through the gap 7. In addition, when the cylindrical case 2 is formed in a continuous form without a gap, a plurality of water passage holes are formed in the caps 4 and 5.

  The electrode rod 3 penetrates the inside of the cylindrical case 2 in the length direction. Both ends of the electrode rod 3 penetrate to the outside of the caps 4 and 5, and the stoppers 6 and 7 are attached to the projected portions to prevent the electrode rod 3 and the caps 4 and 5 from coming off. .

  The cylindrical case 2 is filled with granular activated carbon 8 for adsorbing gas and ions such as oxygen and hydrogen generated by electrolysis of water around the electrode rod 3, and the cylindrical case 2. A nonwoven fabric 9 is provided so as to wrap the activated carbon 8 along the inner circumference. In the figure, reference numerals 10 and 11 denote lead wires connected to the cylindrical case 2 serving as a cathode and the electrode rod 3 serving as an anode, and a lighting circuit 31 of an LED 30 described later is connected to the lead wires 10 and 11. Connected.

The first non-woven fabric 24 wraps the activated carbon 23 integrally, the second non-woven fabric 25 wraps the second electrode plate 22, and the cover 26 made of a synthetic resin film wraps the whole. A water passage portion through which the first and second nonwoven fabrics 24 and 25 are exposed is provided at an appropriate position of the cover 26. In the figure, reference numerals 27 and 28 denote lead wires connected to the first and second electrode plates 21 and 22, respectively.

Power generation can be reliably maintained. In addition, the nonwoven fabrics 9, 24, and 25 prevent the activated carbon 8 and 23 from scattering and also prevent the movement of salts and the like generated at the electrodes, thereby preventing a decrease in power generation performance. Furthermore, since water is held by the water retention property of the nonwoven fabrics 9, 24, 25, power generation is maintained even if the immersion battery 1 is not always immersed in water.
