Description

Technical Field

[0001] The present invention relates to a device for a search object in water to report its own position and a search device.

Background Art

[0002] There are many vehicles that sink at sea, such as ships and aircraft. Although the number of crashes and ship sinkings in which many passengers lose their lives has been decreasing, they still occur. Also, in the air force and the air self - defense force, even when including cases where they want to search for a crashed aircraft no matter what, if it cannot be found after searching for several months, they will give up. In recent years, accidents such as the Singapore Airlines accident in which many passengers went missing and the crash of the F - 35 of the air self - defense force are well - known. More recently, even the helicopter in Okinawa was searched for about two weeks before it was finally discovered, but there were still missing persons.

[0003] In water, radio waves do not reach, and the operation is risky with an electrical mechanism. Therefore, the search has to rely on sonar - based sound wave search from the sea. However, there is a limit to passively searching for objects submerged in water by the reflection of sound waves.

[0004] In the present invention, instead of being passively searched by sonar or the like, the object to be searched actively reports the position where it is submerged, making it easier to be discovered. Also, it can operate reliably without using electricity and can be used without worrying about the power storage period.

Mode for Carrying Out the Invention

[0011] Releasing the gas intermittently for a long time to appear on the water surface, and using the force during gas release to produce sound, Notify the position in water.

Examples

[0012] Example 1 will be described with reference to FIG. 1. Gas at a pressure exceeding 1 atmosphere (101) A container (102) for storing, an opener (103) of the container, an underwater detector (104) for detecting being in water, and the Gas under pressure (101) A discharge port (105) for discharging, and when the underwater detector (104) detects being in water, the opener (103) Opening, the gas under pressure (101) A position reporting device (106) that intermittently and continuously discharges from the discharge port (105) to the water surface to report the position.

[0013] The position reporting device (106) is a device composed of all parts, Gas at a pressure exceeding 1 atmosphere (101) A container (102) for storing, an opener (103) of the container, an underwater detector (104) for detecting being in water, and the GasIt consists of the overall structure of the discharge port (105) that discharges (101) and is not a single hard entity. Also, the discharge port (105) is attached to the opener (103) or is composed of a connected pipe or the like.

[0014] Intermittently means having intervals such as once per second or once every five minutes. Also, the intervals do not have to be constant. They can change each time or change as time passes. Long term refers to long periods such as 30 minutes, 10 days, 3 months, etc., in units of minutes, hours, days, months, years, etc. It is a period that should be designed according to the size of the object to be searched and the range of action. It is not a period that ends within at least a short 5 minutes.

[0015] Discharged intermittently Gas By reaching the object to be searched that should be discovered by chasing after it, the position is reported. It is not a one-time release of floating objects, but can be chased by intermittent release, which facilitates the discovery of the object to be searched. Long-term release is desirable to make it easier to discover objects to be searched that are difficult to search.

[0016] All gases are lighter than water, but even if it is not a gas, such as an oil-based liquid lighter than water, a substance lighter than water, or a solid composite with an overall specific gravity less than 1 including it, it is also possible to report the position by intermittently discharging it.

[0017] The discharge substance is not a gas In the case of solids, it is difficult to operate due to the pressure difference, so it mainly operates by the buoyancy of the solid. In that case, the position of the discharge port (105) must be made higher. Therefore, it must be equipped with a mechanism such as rotating the position reporting device (106) so that the position of the discharge port (105) is always higher.

Example

[0018] An example of the underwater detector (104) composed of a diaphragm (108) deformed by water pressure will be described with reference to FIG. 2. The water pressure detector (107) uses a diaphragm (108) that deforms by detecting water pressure to open and close the opener (103), starting the operation of the position reporting device (106). In the figure, the diaphragm (108) is depressed by water pressure, and the opener (103) is opened through a lever connected to the diaphragm, activating the underwater detector (104). Instead of the diaphragm, a piston and cylinder can also implement this embodiment. A typical example of the opener (103) is a valve, but the opener (103) can also be implemented by a mechanism other than a valve, such as a simple door. This underwater detector (104) is a water pressure detector.

Embodiment

[0019] Example 3 of the underwater detector (104) composed of a water immersion detector that detects water immersion will be described with reference to FIG. 3. This underwater detector (104) is a water immersion detector. The water immersion detector (104) uses a substance (110) whose shape changes, such as expanding when immersed in water, to detect its presence in water. When water enters through a hole (109) provided in the underwater detector container (107) upon immersion, the substance (110) whose shape changes deforms, starting the operation of the opener (103) through a connected lever. The opener (103) is composed of a valve or the like. There are many materials for the substance (110) whose shape changes, such as expanding when immersed in water and containing water, such as water-soluble polymers. A plurality of holes (109) are provided in the underwater detector container (107) at positions of interest and the like to allow air to escape, making it easier to immerse in water.

Embodiment

[0020] Example 4 of the underwater detector (104) composed of a water immersion detector using a float will be described with reference to FIG. 4. This underwater detector (104) is a water immersion detector using a float. When immersed in the water immersion detection container (107), the float rises and moves a crowbar (112) with a fixed fulcrum (113), opening the opener (103). The holes (109) provided in the water detector container (107) are provided in plural at positions such as the target position to allow air to escape, making it easier for water to enter.

[0021] The operation of the opener (103) can be manually operated as necessary regardless of the water detector (104).

Example

[0022] Example 5 will be described with reference to FIG. 5. Gas at a pressure exceeding 1 atmosphere (101) storage container (102), the opener (103) of the container, The gas with high pressure (101) is discharged Having a discharger (201) with an opener (203) and a discharge port (105), and by repeatedly opening and closing the opener (203) of the discharger (201) using the pressure or / and buoyancy of the gas (101), the gas under pressure (101) is A position reporting device (106) that reports the position by intermittently and continuously discharging from the discharge port (105) through the discharger (201) and appearing on the water surface.

[0023] By following the intermittently and continuously discharged substance and reaching the object to be searched that should be discovered, the position is reported. Instead of discharging a one-time floating object, it can be followed by intermittent discharge, making it easier to discover the object to be searched. In order to make it easier to discover an object to be searched that is difficult to search, it is desirable to discharge for a long time, At least It is desirable to discharge for several tens of minutes or more, and it is desirable to discharge on a daily or monthly basis.

[0024] In Example 1 described with reference to FIG. 1, since there is no discharger (201), High-pressure gas In order to continuously discharge (101), the opener (103) of the storage container must be adjusted to discharge little by little, and it is difficult to make it operate stably at any depth. In addition, the opener (103) of the discharger (201) is configured to use a plurality of valves to repeat opening and closing by combining the inflow from the storage container (102) and the discharge from the discharger.

Example

[0025] Example 6 will be described with reference to FIG. 6. Gas at a pressure exceeding 1 atm (101) storage container (102), the opener (103) of the container (102), a water detector (104) for detecting being in water, A discharger (201) having an opener (202) for discharging the gas (101) and a discharge port (105) has, and when the underwater detector (104) detects that it is underwater, the opener (103) of the container (102) Open to Gas (101) By repeating the opening and closing of the opener (202) of the discharger (201) using the pressure or / and buoyancy of the gas, the gas at the pressure (101) intermittently Long term is released to the water surface to report the position, which is a position reporting device.

[0026] The position of the object to be explored underwater to be reported is reported by the gas (101) released to the water surface. Therefore, it is necessary to make the gas (101) on the water surface easy to be discovered. For this purpose, it is important to intermittently emit the gas (101) that reports from underwater to the water surface for a long time. Also, by intermittently emitting the gas (101) to the water surface, the gas (101) can be chased to the release location underwater, and the object being searched for can be discovered. The water surface has both rough wave days and calm days. By releasing for a long time, it will encounter an easy-to-discover day. Note that it is also possible to intermittently release the substance in Example 1, but Example 6 is superior in controlling the water pressure that changes with the water depth and the amount of one-time release required for long-term release.

Example

[0027] Using Fig. 7, an example 7 of the emitter (201) that intermittently Gas (101) releases will be described. With the operation of the opener (103), the opener (301) to the emitter container attached to the emitter container (303) of the emitter (201) and the opener (202) from the emitter container are operated like a seesaw by the connector (302), and the Gas (101) stored in the capacity of the emitter container (303) in the emitter (201) is intermittently released in a set one-time release amount. A comparison device with the external pressure can be attached to the opener (301) to the emitter container and the opener (202) from the emitter container as needed so that the one-time release amount becomes the assumed amount. When the opener (301) to the emitter container and the opener (202) from the emitter container are valves, the valves have hysteresis of the blowing-up pressure and the wiping-down pressure, and this is utilized.

[0028] Next, describe the amount of gas to be saved next and the period for continuously reporting the position. The Gas (101) The gas is stored in a compressed state in the container (102) for storing the gas. In a commonly used high-pressure gas cylinder, the gas is filled at about 150 atmospheres, and it is not impossible to store it at the same pressure. On the other hand, since the water pressure is about 1 atmosphere at a depth of 10 m, this device can operate and release gas even at a depth of about 1000 m underwater. In order to operate at a deeper water depth, the pressure for storing the gas (101) must be increased.

[0029] Even when intermittently releasing gas, if bubbles with a diameter of 2 cm are released once every 5 minutes in shallow water for one year, the size of the container (102) for storing the gas (101) is about 30 cm cubed. It can be realized in a reasonable size on an aircraft or a ship.

[0030] On the other hand, when attaching this device to a person, it may be designed in a small shape with a short intermittent period and a shallow water depth.

[0031] The If the gas (101) is scented, when there is a person nearby, it can be known that there is someone or something nearby asking for help.

Example

[0032] Describe Example 8 using Fig. 8 A position reporting device characterized in that a substance (401) lighter than water that reflects light or exhibits a luminescence phenomenon is discharged along with the discharge of the gas (101), and the gas (101) or / and the substance (401) contains a substance that emits natural light or natural heat when it comes into contact with air.

[0033] Even if the gas (101) is released and appears on the water surface (402), the water surface (402) is often wide and difficult to discover. Therefore, a substance (403) that spontaneously ignites (404) in the air is used for the gas (101) to emit light and make it easier to discover especially at night. If it ignites, light and heat are emitted in many phenomena. Since it is desirable to emit light and heat with as much energy as possible, a substance (403) that ignites spontaneously (404) is mixed with a petroleum-based volatile gas that emits a large amount of energy, and it is designed to ignite the volatile gas from the spontaneously ignited substance (403), so that a large amount of light can be emitted. Light is easy to be discovered even from a distance or if it is small at night. The possibility of heat being detected by an infrared detector also increases.

Example

[0034] Example 9 will be described with reference to FIG. 9 Even if a substance lighter than water is released and appears on the water surface (402), the water surface (402) is often difficult to be widely discovered. Therefore, a substance (401) with a luminescence phenomenon such as glass that reflects light or fluorescence or phosphorescence that reacts to light is mixed into the substance and incorporated into a solid structure lighter than water, etc. It sparkles during the day and is easier to discover when illuminated by a light at night.

[0035] Make a solid with a specific gravity less than 1 containing minerals such as sodalite and make it float on water. By including gas in the solid, etc., it is easy to make the specific gravity less than 1. You may make a substance on the particle that is easy to reflect light with a resin lighter than water. It is also possible to put a fluorescent substance such as a seamarker in a capsule and release it on water. The release of such a substance is easy to be discovered even in a short time and is then carried out intermittently Gas (101) can be chased in water and reach the object to be searched.

Example

[0036] Next Figure 10 A position reporting device (106) will be described which is characterized in that at least a solid lighter than water or a liquid lighter than water (1001) is released along with the release of the gas (101) using

[0037] Since it is difficult to control the movement of solids and liquids by pressure, they often need to be operated by buoyancy. Place the center of gravity on the side opposite to the discharge valve so that the discharge valve always faces upward. In this case as well, since it is necessary to consider the up and down orientation of the position reporting device (106), use the mechanism described later.

[0038] Or a gas (101) in the flow path of the gas (101) is sucked out by the pressure of the flow path of the gas and mixed into the gas (101) and discharged. Design the capsule so that it opens on the water surface with the solid incorporated as a curtain in the capsule. Initially discharge it so that the curtain opens and is made easy to discover with a substance that reflects light. Since the area of the curtain can be large, it is easy to be discovered. Instead of the curtain, a liquid such as a seam marker may be put in. After that, intermittently discharging substances also facilitates the discovery of the object to be searched for.

[0039] In addition to the substance that enhances visibility by light, for example, by discharging components such as blood where fish gather or substances with the smell of bait, fish gather, and discovery is facilitated by fish school detection.

[0040] The gas (101) is stored at an appropriate pressure, and that pressure needs to be the pressure that operates at the water pressure within the applicable range. When the pressure of the gas (101) is higher than the water pressure, a device that operates regardless of the up and down orientation of the position reporting device (106) can be configured. It is also possible to provide an outlet from another container for solids or liquids at the pressure of the gas (101) in the flow path for discharging the gas (101) by a pressure difference and mix it into the gas (701) and discharge it.

Example

[0041] Describe Example 11 using Figure 11 The position reporting device (106) Is free to rotate or move and has a position control mechanism (501) such that the discharge port is always upward. When the pressure in the water is higher than the pressure of the gas in the container (102), water is introduced into the container (102) from the lower side opposite to the upward-facing discharge port by the attitude control mechanism (501) so that the pressure of the container (102) and each part is the same as the water pressure or the pressure difference of the water pressure is below the initial pressure resistance of the container (102), thereby avoiding the destruction of the container and each part, and further continuing the operation by the buoyancy of the gas.

[0042] Place the position reporting device (106) in a container forming a position controller (501) that can rotate freely, and place the center of gravity (503) of the position reporting device (106) and the position reporting device so that the discharge port (105) of the position reporting device faces upward.The center of buoyancy (503) when fully submerged is made to come to the opposite side across the rotation axis (502), and further the discharge port (105) is made to come to the side of the center of buoyancy (503) as seen from the rotation axis (502). Also, the rotation is not two-dimensional but three-dimensional, and a two-axis correspondence or the like is provided so that it can rotate in any direction.

[0043] When it operates by buoyancy rather than pressure, the path of the gas (101) or a substance lighter than water that is released so that the position reporting device (106) operates must be designed so that it always goes upward toward the discharge port (105).

Embodiment

[0044] Embodiment 12 will be described with reference to FIG. 12. The position reporting device (106) is a position reporting device (106) that can move freely and has a mechanism for controlling the position so that the discharge port (105) is always upward, and can be connected to the object to be searched (507) by a cable (508). The center of gravity (403) of the position reporting device (106) is made to be on the side opposite to the discharge port (105) with respect to the center of buoyancy (504) when the entire position reporting device is submerged so that the discharge port (105) of the position reporting device (106) comes upward.

[0045] Object to be searched (507) When the overall specific gravity of is less than 1, the connection by the cable (508) is With respect to the center of buoyancy (504) connected to the center of gravity (503) side, Object to be searched (507) When the overall specific gravity of is greater than 1, the connection position (405) by the cable is connected to the discharge port (105) side. Also, with the operation of the underwater detector (104), the fixation between the position reporting device (106) and the object to be searched (507) is released so that it can move freely in water.

[0046] When the pressure of the gas (101) exceeding 1 atm is greater than the pressure of the external water pressure, it operates regardless of the up and down directions. However, when the external water pressure is greater than the pressure of the gas exceeding 1 atm, it is necessary to rotate or the like so that the discharge port (105) faces upward considering the up and down directions of the container. Gas This is because it has the property of going upward in water.

[0047] External Water pressure The In the storage container (102) The If the pressure is greater than the pressure of the gas (101), add water little by little from the outside to the container (102) to The pressure inside the container (102) can be increased and maintained below the breaking pressure resistance of the container (102). For this purpose, it is necessary to provide a special water depth (water pressure) detector and a circuit that allows water to enter the inside of the container (102) from the outside. Even in this case, the circuit is provided with a valve that allows water to enter only the inside.

[0048] Alternatively, a check valve is simply provided, and if the external pressure increases above the pressure of the internal gas (101), the valve opens and water flows into the inside. Due to this inflow, the pressure inside the container (102) increases, the pressure difference between the inside and outside decreases, and damage does not occur. With this method, a device that operates regardless of the pressure resistance of the container can be made in the deep sea with any water pressure.

[0049] When operating only with the pressure at which the pressure difference has decreased, the period during which gas can be released becomes shorter as the water depth increases. This is because when water is taken into the container (102) from the outside, the pressure inside the container (102) increases, and even for the same volume of gas, the amount released in one time increases. Also, if the bubbles themselves are not of a certain size, buoyancy is lost.

[0050] In the initial stage of operation of this device, the gas (101) By emitting the signal at short intervals and lengthening the intervals as time passes, the signal can be easily detected and can be detected even over a long period of time. EXAMPLES

[0051] Example 13 will be described with reference to FIG. 13. The position notification device (106) is characterized by emitting a sound in response to the opening and closing operations of the opener (301) to the emitter container (303) attached to the emitter container (303) in the emitter (201) and the opener (202) from the emitter container (303). The opener (301) to the emitter container (393) and the opener (202) from the emitter container (303) repeatedly open and close like a seesaw via the connecting tool (302). A hammer (601) is attached to this connecting tool (302) and is struck from the inside or outside of the emitter container (303) at a part that is efficient for producing sound, such as a metal part. Alternatively, the hammer (601) is struck against the flow path. the gas (101) It moves by striking parts of the container and produces sound. EXAMPLES

[0052] Example 14 will be described with reference to FIG. 14. The emitter (201) is depressurized to a high pressure against the water pressure from the container (102) that stores the gas (101), through the opener (103) of the storage container and further through the regulator (701), and stored in the emitter container (303). The emitter (202) attached to the emitter (201) intermittently the releases the gas (101), which is a feature of the position reporting device (106).

[0053] Since the internal pressure of the discharge container (303) of this emitter (201) can be designed to be higher than the pressure of the external water depth by the regulator (701), the position reporting device (106) can operate without using the buoyancy of the gas (101) and regardless of the vertical positional relationship. Also, the regulator (701) and the emitter (202) from the emitter container (303) are made to cooperate with each other by the connector (302) so that the timing of intermittent discharge can be achieved. By designing the capacity of the emitter container (303), the discharge amount per time can also be controlled.

[0054] with the gas (101) As shown in FIG. 14, it is easy to make a device that operates based on a pressure difference rather than buoyancy. In Example 14, the difference in pressure due to depth can be absorbed, but the amount of gas released increases as the pressure increases, that is, the deeper the depth. Therefore, the capacity of the emitter container (303) should be smaller the deeper it is. For this purpose, it is advisable to make the capacity of the container (303) decrease by being crushed by a spring and a piston or by water pressure. However, the capacity of the container (303) can only be reduced to a bubble size of about several tens of microns, and if it becomes smaller than that, there is a risk of not floating due to buoyancy.

[0055] Also, since the regulator (701) must detect the external water pressure, it must be connected to the outside. In FIG. 14, it is shown by the symbol of one valve, but the regulator (701) may be composed of a plurality of valves.

Example

[0056] Example 15 will be described with reference to FIG. 15. When the amount of the gas (101) in the storage container (102) that stores the gas (101) decreases, the position reporting device (106) generates gases (803), (804), and (805) by the reaction of a solid (801) and / or a liquid (802) separately stored in the storage container (102) to increase the amount of the gas (101) in the storage container (102).

[0057] For gas generation, there are gases (803) generated from a solid and a liquid, gases (804) generated from two or more solids (801), gases (805) generated from two or more liquids (802), and gases (804) and (805) generated from one solid (801) or one liquid (802). For example, if a fuse is attached to gunpowder and it is struck, gas is generated from one solid (801).

[0058] For the reaction between liquids, solids, and a liquid and a solid, substances that react to generate gas even in the absence of the presence of gas, particularly air or oxygen in the air, are required. For example, gunpowder generates gas from only solids without oxygen. This mechanism may be any one of the reactions between solids (801), the reactions between liquids (802), and the reaction between a solid (801) and a liquid (802), and a combination that generates more gas is desirable. In the figure, the solid (801) and the liquid (802) are shown as one circle, but when reacting between solids (801) or between liquids (802), there are often a plurality of types of solids (801) or liquids (802). However, even with just one type of solid (801) and liquid (802), it is only necessary to give a stimulus to substances that react upon stimulation. Gunpowder and the like are good examples.

[0059] When the external water pressure becomes higher than the pressure of the gas (101) inside the storage container (102) of the position reporting device (106), water can be put into the container to make the pressure of the gas (701) inside the storage container (102) the same as the external water pressure without causing the destruction of the storage container (102). This mechanism works no matter how deep the water is. Therefore, the pressure resistance of the storage container (102) only needs to be designed to withstand the initial gas (701) pressure.

[0060] It is easy to install a one-way valve from the outside to the inside in the downward direction by attitude control to put water inside the storage container (102). When the external pressure becomes higher than the internal pressure, the valve will automatically open to allow water to enter the inside of the storage container (102).

[0061] If the external water pressure approaches or exceeds the pressure of the gas (101) inside the storage container (102), water is introduced from outside the storage container (102) to make the pressure of the internal gas (701) the same as the outside. Moreover, by generating gas (701) inside the storage container (102), gas (1004) generated from the solid and liquid, gas (1005) generated from the solid, and gas (1006) generated from the liquid can be obtained, and the pressure of the gas (101) inside the storage container (102) can be made higher than the external water pressure again.

[0062] Even in this case, the pressure resistance of the storage container (102) is only the difference between the external water pressure and the internal gas (101), so a large pressure resistance is not required and the initial design is sufficient. In this way, a position reporting device (106) that operates in any deep sea is realized.

[0063] Alternatively, when the pressure of the gas inside the storage container (102) and the external water pressure are close, it is also possible to react solids (801), liquids (802), and two or more types of each of the solids (801) or liquids (802) with each other, or the solid (801) and the liquid (802) without putting in external water to generate gases (803)(804)(805) to always keep the internal pressure higher than the outside. In this case, the internal pressure can be increased up to the pressure resistance of the container, and the operation can continue in any deep sea with the initial design operation.

[0064] Since the trigger for the reaction is the external water pressure, a mechanism is required to detect this water pressure and mix the stored solid (801) and the stored liquid (802) together. Various methods can be considered, such as a partition that is broken by water pressure. Alternatively, there are also methods such as pulling a trigger by water pressure to ignite gunpowder.

Example

[0065] Example 16 will be described with reference to FIG. 16. The position reporting device is characterized in that the amount of gas (903) released each time is increased or decreased according to the water depth. To achieve this, an opener connected to the emitter container (303) is used as a capacity adjustment opener (901) to the emitter container and a capacity adjustment opener (902) from the emitter container to adjust the discharge amount. Alternatively, it can be implemented by changing the capacity of the discharge container (302) with a piston with a spring or the like according to the water pressure.

[0066] When the water pressure increases, the bubbles become smaller. If they become too small, they will dissolve in the water and not float up. Bubbles must be at least several tens of microns or more. For example, a bubble with a diameter of 2 cm on the water surface (1 atm) will have a pressure of 500 atm and a diameter of 40 microns in water at a depth of 5000 m. Considering the volume of gas dissolved in water according to Henry's law, it is slightly too small. Deeper than this, the bubbles may be too small to float.

[0067] On the other hand, when the water pressure increases, it is necessary to change the size of the bubbles according to the water depth, such as making the bubbles smaller and making the amount of gas released at one time as the same as possible. As the bubbles rise, the water pressure decreases and the size becomes larger.
