Position reporting device

Abstract

To facilitate the early discovery of objects to be searched underwater, such as aircraft, ships, people, and various recorders submerged in water due to an accident. The searched item will also report its own location, making it easier to find. [Solution] Position reporting is done by releasing gas for a long period of time. By releasing gas intermittently, it is possible to track the creation underwater, not just discover it on the surface. It makes it easier to find the released material on the surface. The gas flow generated when bubbles are released is used to create sound underwater. Releasing it for a long period of time makes it easier to detect.

Description

[Technical field]

[0001] The present invention relates to a device for reporting the position of a search object underwater and a search device. [Background technology]

[0002] Many vehicles, such as ships and aircraft, sink in the ocean. Although the number of plane crashes and ship sinkings in which many passengers lose their lives is decreasing, they still occur. Even in cases where the Air Force or Japan Air Self-Defense Force crashes and they are desperate to find the vehicle, they give up after several months of searching. In recent years, the Singapore Airlines accident, in which many passengers went missing, and the crash of the Japan Air Self-Defense Force's F35 are well-known. Recently, a helicopter in Okinawa was finally found after about two weeks of searching, but there were still missing people.

[0003] It is true that radio waves cannot reach underwater, and electrical systems are dangerous to operate. Therefore, searches must rely on sonar to detect sound waves from the surface. However, there are limitations to passively searching for submerged objects by reflecting sound waves.

[0004] In the present invention, rather than being passively searched for using sonar or the like, the object being searched for actively reports its own submerged location, making it easier to find. In addition, it operates reliably without using electricity, and can be used without worrying about the shelf life of the power source. [Prior art documents] [Patent documents]

(Example 4) [Diagram 5] This is one form of position reporting device using an emitter. (Example 5) [Figure 6] This is one form of position reporting device that uses an underwater detector and emitter. (Example 6) [Figure 7] This is one form of emitter. (Example 7) [Figure 8] This form is intended to make it easier to find on the water by emitting light. (Example 8) [Figure 9]This shape is designed to make it easier to find on the water by using reflection. (Example 9) [Figure 10] This is a form in which a substance lighter than water is released along with the release of the substance. (Example 10) [Figure 11] This is the form when the water pressure exceeds the internal air pressure. (Example 11) [Figure 12] This is another example where the water pressure exceeds the internal air pressure. (Example 12) [Figure 13] It produces a sound when the substance is released. (Example 13) [Figure 14] This is a form of emitter using a regulator. (Example 14) [Figure 15] This is one form of position reporting device that increases the internal gas. (Example 15) [Figure 16] The amount of gas released each time is changed depending on the water depth. (Example 16) DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] It releases gas intermittently for a long period of time, causing it to appear on the surface of the water, and also uses the force of the gas release to create sound. Communicate your underwater location. EXAMPLES

[0012] The first embodiment will be described with reference to FIG. Gases at pressures above 1 atmosphere A container (102) for storing (101), an opener (103) for the container, an underwater detector (104) for detecting the presence of the container in water, and Gas under pressure (101) and the underwater detector (104) detects that the device is underwater and opens the opener (103). Release the gas at the pressure The position reporting device (106) reports its position by intermittently releasing the target (101) from the release port (105) for a long period of time and making it appear on the water surface.

[0013] The location reporting device (106) is a device made up of each part as a whole, Gases at pressures above 1 atmosphere A container (102) for storing (101), an opener (103) for the container, an underwater detector (104) for detecting the presence of the container in water, and gasThe discharge port (105) is composed of the entire structure that discharges the discharge gas (101) and is not a single piece of hardware. The discharge port (105) is attached to the opener (103) or is composed of piping connected to the opener (103).

[0014] Intermittent means having intervals such as once per second or once per five minutes. The interval does not have to be constant. It may change every time, or it may change over time. Long-term means a long period of time such as 30 minutes, 10 days, or 3 months, or a period of minutes, hours, days, months, or years. This period should be designed according to the size of the object to be searched and its range of movement. At least, it's not a period that lasts less than five minutes.

[0015] Emitted intermittently gas By tracking the object, the system will reach the object to be found and report its location. Rather than releasing floating objects once, intermittent releases allow tracking, making it easier to find the object. Long-term releases are desirable to make it easier to find objects that are difficult to find.

[0016] All gases are lighter than water, but even if they are not gases, liquids that are lighter than water, such as oils, and compounds of solids that are lighter than water and contain them and have an overall specific gravity of less than 1, can also report their location by emitting them intermittently.

[0017] The emission is not gas. In the case of a solid object, it is difficult to operate it based on the difference in pressure, so it is mainly operated by the buoyancy of the solid object. In that case, the position of the discharge port (105) must be on top. Therefore, a mechanism must be provided to rotate the position reporting device (106) so that the discharge port (105) is always on top. EXAMPLES

[0018] A second embodiment of the underwater detector (104) comprising a diaphragm (108) that is deformed by water pressure will be described with reference to FIG. The water pressure detector (107) detects water pressure and opens and closes the opening device (103) using a diaphragm (108) that deforms, thereby starting the operation of the position reporting device (106). In the figure, the diaphragm (108) is depressed by water pressure, and the opening device (103) is opened through a lever connected to the diaphragm, thereby activating the underwater detector (104). This embodiment can also be realized by using a piston and a cylinder instead of the diaphragm. A typical example of the opener (103) is a valve, but the opener (103) can also be realized by a mechanism other than a valve, such as a simple door. The underwater detector (104) is a water pressure detector. EXAMPLES

[0019] A third embodiment of the underwater detector (104) that is a water submersion detector for detecting water submersion will be described with reference to Fig. 3. The underwater detector (104) is a water submersion detector. The water ingress detector (104) detects when it is underwater by using a substance (110) that changes shape, for example by expanding, when it is submerged in water. When water enters through a hole (109) provided in the underwater detector container (107), the shape-changing substance (110) deforms, and starts the operation of the release device (103) through a connected lever. The release device (103) is composed of a valve or the like. There are many materials for the substance (110) that changes shape, for example by expanding, when it is submerged in water and absorbs water, such as water-soluble polymers. Multiple holes (109) are provided in the underwater detector container (107) at the target position or elsewhere to allow air to escape, making it easier to ingress water. EXAMPLES

[0020] A fourth embodiment of the underwater detector (104) configured as 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 water enters the water detection container (107), the float rises to the surface, moving the lever (112) to which the fulcrum (113) is fixed, thereby opening the release switch (103). The underwater detector container (107) has a plurality of holes (109) at the target position or the like to allow air to escape, making it easier for water to enter.

[0021] The operation of the opener (103) does not depend on the underwater detector (104), but can be manually operated if necessary. EXAMPLES

[0022] The fifth embodiment will be described with reference to FIG. Gases at pressures above 1 atmosphere A container (102) for storing (101), and an opener (103) for said container; The high pressure gas Emit (101) The device has a discharger (201) having an opener (203) and a discharge port (105), and the device uses the pressure and / or buoyancy of the gas (101) to repeatedly open and close the opener (203) of the discharger (201) to discharge the gas (101) at the pressure. The position reporting device (106) reports the position by intermittently releasing the radioactive material from the release port (105) through the emitter (201) for a long period of time and making it appear on the water surface.

[0023] By tracking the substance released intermittently over a long period of time, the location of the object to be found is reported. Instead of releasing floating objects only once, the object can be tracked by releasing it intermittently, making it easier to find the object. at least It is desirable to release the material for several tens of minutes or more, and preferably for a period of days or months.

[0024] In the first embodiment described in FIG. 1, since there is no emitter (201), High pressure gas In order to continuously release (101), the release device (103) of the storage container must be adjusted to release it little by little, and it is difficult to make it operate stably at any depth. In addition, the opener (103) of the emitter (201) can be realized by using multiple valves to combine the inflow from the storage container (102) and the release from the emitter, and to repeatedly open and close the valves. EXAMPLES

[0025] The sixth embodiment will be described with reference to FIG. Gases at pressures above 1 atmosphere A container (102) for storing the (101), an opener (103) for the container (102), and an underwater detector (104) for detecting the presence of the container in water. A discharger (201) having an opener (202) and a discharge port (105) for discharging the gas (101)When the underwater detector (104) detects that the container (102) is underwater, the opener (103) of the container (102) is opened. open The above gas (101) The pressure and / or buoyancy of the gas is utilized to repeatedly open and close the opening (202) of the releaser (201), thereby releasing the gas of the pressure. (101), intermittently long term It is a position reporting device that reports its location by being released into the water and emerging above the water.

[0026] A search object underwater that needs to report its position reports its location by releasing gas (101) onto the water surface. For this reason, it is necessary to make the gas (101) on the water surface easy to find. For this reason, it is important to release the gas (101) to be reported from underwater to the surface intermittently for a long period of time. Also, by releasing the gas (101) onto the water surface intermittently, it is possible to track the gas (101) underwater to the point where it was released, and discover the object being searched for. On the water surface, there are days with high waves and days with completely calm seas. By releasing the gas for a long period of time, it will be easier to come across the object on a day when it is easier to find it. Although it is possible to intermittently release a substance in Example 1, Example 6 is superior in terms of controlling the water pressure that changes with water depth and the amount of material released at one time that is required for long-term release. EXAMPLES

[0027] Intermittent use of Figure 7 Gas (101) A seventh embodiment of the emitter (201) will now 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 connecting device (302), and the water stored in the capacity of the emitter container (303) in the emitter (201) is released. gas (101) intermittently discharges the set amount of discharge at one time. If necessary, the opener (301) to the discharger container and the opener (202) from the discharger container can be equipped with a comparison device with the external pressure to ensure that the amount of discharge at one time is the expected amount. If the opener (301) to the discharger container and the opener (202) from the discharger container are valves, the valves have hysteresis between the blow-up pressure and the wipe-down pressure, and this is utilized.

[0028] Next we will discuss the amount of gas to be stored and the period for which the position will be reported. The above gas (101) The gas is compressed and stored in the container (102) that stores the gas. Generally used high pressure gas cylinders are filled with gas at about 150 atmospheres, so it is not difficult to store gas at the same pressure. On the other hand, water pressure is about 1 atmosphere at a depth of 10 m, so this device can operate and release gas even at a depth of about 1000 m underwater. In order to operate at a depth deeper than this, the gas must be (101) There must be increased pressure to preserve it.

[0029] Even when gas is discharged intermittently, if gas bubbles with a diameter of 2 cm are discharged once every 5 minutes for one year in shallow water, the size of the container (102) for storing the gas (101) is about 30 cm cubic, which is a reasonable size to be realized in an airplane or ship.

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

[0031] The above By adding an odor to the gas (101), if someone is present, it will be possible to tell that there is someone or something nearby that needs help. EXAMPLES

[0032] Example 8 will be described with reference to FIG. 8. This position reporting device is characterized in that as the gas (101) is released, a substance (401) lighter than water that reflects light and / or emits luminescence is released, and the gas (101) and / or the substance (401) contain a substance that spontaneously emits light or generates heat when exposed to air.

[0033] Even if the gas (101) is released and appears on the water surface (402), it is often difficult to find the water surface (402). Therefore, a substance (403) that spontaneously combusts in air (404) is used in the gas (101) to make it glow, making it easier to find, especially at night. In many cases, light and heat are emitted when a fire occurs. It is desirable to emit light and heat with as much energy as possible, so by mixing a spontaneously combusting substance (403) with a petroleum-based volatile gas that emits a lot of energy, and designing it so that the spontaneously combusting substance (403) ignites the volatile gas, a large amount of light can be emitted. Light can be easily seen at night, even from a distance, and even if it is small, and heat is also more likely to be picked up by infrared detectors. EXAMPLES

[0034] Example 9 will be described with reference to FIG. Even if a substance lighter than water is released and appears on the water surface (402), it is often difficult to find the water surface (402). For this reason, the substance is mixed with light-reflecting glass or a substance (401) that reacts to light and has a luminescence phenomenon such as fluorescence or phosphorescence, and incorporated into the structure of a solid that is lighter than water. It shines brightly even during the day, and is illuminated with a light at night to make it easier to find.

[0035] For example, you can create a solid containing minerals such as sodalite with a specific gravity less than 1, and make it float on water. It is easy to make the specific gravity less than 1 by including gas in the solid. You can also create a granular material out of resin that is lighter than water and easily reflects light. Fluorescent materials such as sea markers can be encapsulated and released on the surface of the water. Such releases are easily detectable for short periods of time, then are intermittent. gas The (101) emission can be followed underwater to reach the searched object. EXAMPLES

[0036] next Figure 10 In the present embodiment, a position reporting device (106) is described that is characterized in that it releases at least a solid or a liquid (1001) lighter than water when the gas (101) is released.

[0037] Since it is difficult to control the movement of solids and liquids by pressure, it is necessary to operate them by buoyancy. The center of gravity should be placed on the opposite side of the release valve so that the release valve always faces upward. In this case, the up-down orientation of the position reporting device (106) must also be taken into consideration, so a mechanism described later is used.

[0038] Or gas (101) The gas is introduced into the flow path of (101) The gas is sucked out by the pressure of the flow path and mixed with the gas (101) and released. A solid could be incorporated into the capsule as a curtain, designed to open when the capsule is on water, and released early to open the curtain, making it easier to spot with a light-reflecting material. The surface area of ​​the curtain could be made large, making it easier to spot. Instead of a curtain, you can also use a liquid such as a sea marker. The substance continues to be released intermittently thereafter, making it easier to find the searched item.

[0039] In addition to the above-mentioned substances that enhance visibility by light, substances that attract fish, such as blood components or substances that smell like food, can be emitted, which attract fish and make it easier to find them by fish detection, etc.

[0040] The gas (101) must be stored at a suitable pressure, and the pressure must be such that the gas can operate within the applicable range of water pressure. If the pressure of the gas (101) is higher than the water pressure, the position reporting device (106) can be configured to operate regardless of the upside-down orientation. It is also possible to provide a discharge port from another container for solids or liquids at the pressure of the gas (101) in the flow path that discharges the gas (101) by pressure difference, and discharge the solids or liquids mixed with the gas (701). EXAMPLES

[0041] Example 11 will be described with reference to FIG. The position reporting device (106) is a position reporting device that can rotate or move freely and has a position control mechanism (501) so that the outlet is always at the top. When the pressure in the water becomes higher than the pressure of the gas in the container (102), the attitude control mechanism (501) pours water into the container (102) from the bottom opposite the upward-facing outlet, thereby making the pressure in the container (102) and each part the same as the water pressure or making the difference in water pressure equal to or lower than the initial pressure resistance of the container (102), thereby preventing damage to the container and each part and allowing it to continue operating by the buoyancy of the gas.

[0042] The position reporting device (106) is placed in a container forming a freely rotatable position controller (501), and the center of gravity (503) of the position reporting device (106) and the position reporting device are aligned so that the discharge port (105) of the position reporting device (106) is at the top. The center of buoyancy (503) when completely submerged is positioned on the opposite side of the rotation axis (502), and the discharge port (105) is positioned on the side of the center of buoyancy (503) when viewed from the rotation axis (502). In addition, rotation is not two-dimensional but three-dimensional, with two-axis support so that it can rotate in any direction.

[0043] If it operates by buoyancy rather than pressure, it must be designed so that the path of the gas (101) or any substance lighter than water released to operate the position reporting device (106) is always upward toward the release port (105). EXAMPLES

[0044] The twelfth embodiment will be described with reference to FIG. The position reporting device (106) is a position reporting device (106) that is freely movable and has a mechanism that can control its position so that the discharge port (105) is always at the top, and is connected to the searched object (507) by a cable (508). The center of gravity (403) of the position reporting device (106) is set to be on the opposite side of 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) is located at the top.

[0045] Searched Items(507) If the total specific gravity of is less than 1, the connection by cable (508) is With respect to the center of buoyancy (504) Connected to the center of gravity (503) side, Searched Items(507) If the total specific gravity is greater than 1, the cable connection point (405) is connected to the outlet (105) side. In addition, in response to the operation of the underwater detector (104), the position reporting device (106) and the searched object (507) are released from their fixed positions, allowing them to move freely underwater.

[0046] If the pressure of the gas (101) exceeding 1 atmosphere is greater than the external water pressure, it will work regardless of the up and down orientation. However, if the external water pressure is greater than the gas pressure exceeding 1 atmosphere, it is necessary to take into account the up and down orientation of the container and rotate it so that the outlet (105) faces upwards. gas This is because water has the tendency to move upwards.

[0047] External Water pressure The above In the storage container (102) The above 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 vessel (102) can be increased and maintained below the vessel's (102) burst pressure. 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] Or, simply provide a check valve, and when the outside pressure becomes higher than the pressure of the gas inside (101), the valve opens and allows water to flow in. This inflow increases the pressure inside the container (102), reducing the pressure difference between the inside and outside, and preventing damage. This method makes it possible to create a device that can operate at any depth and at any pressure, regardless of the pressure resistance of the vessel.

[0049] When the device operates only on the pressure with the pressure difference reduced, the period during which gas can be released becomes shorter as the water depth increases. This is because the pressure inside the container (102) increases when water is taken into the container (102) from the outside, and the amount of gas released at one time increases even with the same volume of gas. Also, if the air bubbles themselves are not large enough, they will lose buoyancy.

[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 a gas storage vessel (102) that stores the gas (101), and the gas is decompressed to a pressure higher than the water pressure through a storage vessel opener (103) and a regulator (701) and stored in the emitter vessel (303). The gas is then intermittently discharged by an opener (202) from the emitter vessel (303) attached to the emitter (201). The above The position reporting device (106) is characterized by emitting gas (101).

[0053] The internal pressure of the discharge container (303) of this discharger (201) can be designed by the regulator (701) to be higher than the external water depth pressure, so that the position reporting device (106) can operate without utilizing the buoyancy of the gas (101) and regardless of its vertical position. In addition, the regulator (701) and the releaser (202) from the releaser container (303) can be linked together by the connector (302) to allow for timing of intermittent release. The amount of each release can also be controlled by designing the capacity of the releaser container (303).

[0054] Gas (101) It is easy to make a device that operates on pressure difference rather than buoyancy, as shown in Figure 14. In the fourteenth embodiment, the difference in pressure due to depth can be absorbed, but the amount of gas released increases as the pressure increases, i.e., the depth increases. Therefore, the capacity of the releaser container (303) should be smaller the deeper it is. To achieve this, it is recommended that the capacity of the container (303) be made smaller by using a spring and a piston, or by being crushed by water pressure. However, the capacity of the container (303) can be reduced only until the size of the air bubbles reaches about several tens of microns, and if the size of the air bubbles is smaller than that, there is a risk that the air bubbles will not float due to buoyancy.

[0055] Also, the regulator (701) must be connected to the outside because it must detect the external water pressure. Although FIG. 14 shows a symbol for one valve, the regulator (701) may be composed of multiple valves. EXAMPLES

[0056] A fifteenth embodiment will be described with reference to FIG. The position reporting device (106) is a position reporting device characterized in that when the amount of gas (101) in the storage container (102) storing the gas (101) becomes low, gas (803), (804), (805) is generated by a reaction of a solid (801) and / or a liquid (802) separately stored in the storage container (102), thereby increasing the amount of gas (101) in the storage container (102).

[0057] There are several types of gas generation: gas generated from a solid and a liquid (803), gas generated from two or more solids (801) together (804), gas generated from two or more liquids (802) together (805), and gas generated from a single solid (801) or a single liquid (802) (804) (805). For example, if you attach a fuse to gunpowder and strike it, gas will be generated from a single solid (801).

[0058] Liquid-liquid, solid-solid, and liquid-solid reactions require a substance that can react to produce a gas without the presence of air or the oxygen in air. For example, gunpowder produces gas from solids alone, without oxygen. This mechanism may be any one of a reaction between solids (801), a reaction between liquids (802), or a reaction between a solid (801) and a liquid (802), and a combination that generates a larger amount of gas is preferable. In the figure, a solid (801) and a liquid (802) are shown as a single circle, but when reacting two solids (801) together or two liquids (802) together, there are often multiple types of solids (801) or liquids (802) involved. However, if a substance is simply one type of solid (801) or liquid (802), it only needs to be stimulated to react to the stimulus. Gunpowder is a good example.

[0059] If the external water pressure becomes higher than the pressure of the gas (101) inside the storage container (102) of the position reporting device (106), the pressure of the gas (701) inside the storage container (102) can be made equal to the external water pressure by pouring water into the container without causing the storage container (102) to break down. This mechanism works even in deep water. Therefore, the pressure resistance of the storage container (102) only needs to be designed so that it can withstand the initial pressure of the gas (701).

[0060] The easiest way to fill the storage container (102) with water is to attach a one-way valve from outside to inside to the side that is lowered by attitude control. When the outside pressure becomes higher than the inside pressure, the valve automatically opens and water enters 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 poured into the storage container (102) from the outside to make the pressure of the gas (701) inside the storage container (102) the same as the outside. Then, 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 are 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 necessary and the initial design is sufficient. In this way, a position reporting device (106) that can operate at any depth in the sea is realized.

[0063] Alternatively, when the gas pressure inside the storage container (102) becomes close to the pressure of the water outside, it is possible to make the internal pressure higher than the external pressure by reacting solids (801) and liquids (802), or two or more types of solids (801) or liquids (802), or solids (801) and liquids (802) together to generate gases (803), (804), and (805) without adding water from the outside. In this case, the internal pressure can be increased to the pressure resistance of the container, and it can continue to operate at any depth in the sea as originally designed.

[0064] The trigger for the reaction is external water pressure, so a mechanism is required to detect this water pressure and mix the stored solid (801) and stored liquid (802) into one. Various methods are possible, such as a partition that is destroyed by water pressure. Another method is to have a trigger pulled by water pressure to ignite explosives. EXAMPLES

[0065] The sixteenth embodiment will be described with reference to FIG. The position reporting device is characterized in that the amount of gas (903) released each time is increased or decreased depending on the water depth. To achieve this, the openers connected to the emitter container (303) are a volume-adjusting opener (901) to the emitter container and a volume-adjusting opener (902) from the emitter container, which adjust the amount of discharge. Alternatively, the volume of the discharge vessel (302) can be changed by water pressure using a spring-loaded piston or the like.

[0066] As the water pressure increases, the bubbles become smaller. If they become too small, they will dissolve in the water and will not float to the surface. The bubbles must be at least several tens of microns in size. For example, a bubble with a diameter of 2 cm at the surface (1 atmosphere) will be at 500 atmospheres at a depth of 5,000 m underwater, and its diameter will be 40 microns. This is slightly too small when considering the volume of gas that can dissolve in water according to Henry's law. If it goes deeper than this, the bubbles may be too small to float to the surface.

[0067] On the other hand, when the water pressure increases, it is necessary to change the size of the bubbles depending on the water depth, for example by making the bubbles smaller so that the amount of gas released at one time is as constant as possible. As the bubbles rise, the water pressure decreases and they become larger. [Explanation of symbols]
