Abstract

PURPOSE:To instantly generate bubbles even in highly pressurized water when the bubble generating device is discharged by disposing elastic bodies having repulsing force as large as it exceeds the water pressure force exerted on the contact surface of the packing between the piling-up layers of the chemical agent forming bodies which react with water to generate gas. CONSTITUTION:Plural chemical agent forming bodies 3 which generates gas by the reaction with water are piled up in a cylindrical vessel 1a. The piled-up state of the plural chemical agent forming bodies is kept by the joining means consisting of an upper pressing plate 15, a lower pressing plate 16, connecting belts 17 and a link 21, and the joining means is released by a safety pin 23. The elastic bodies 7 are disposed between the surfaces of piled-up layers of chemical agent forming bodies 3 to energize in the piling-up direction. As a result, when the bubble generating device is discharged to the outside of discharge cylinder, the device is instantly and surely separated into each vessel to generate bubbles even in highly pressurized water.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a bubble generator, in particular a bubble generating device that stores therein a chemical that generates bubbles when released into water, and quickly generates bubbles under high water pressure. The present invention relates to a device suitable for generating bubbles and an easy-to-operate device for generating bubbles.

[Conventional technology]

As shown in Fig. 9, the bubble generator that generates bubbles when released into water is a device that is opened at one end inside a storage outer cylinder 4G that is cut off from contact with the outside air, and that reacts with water. Chemicals that generate air bubbles (chemical compression molded products) 4
A device is known in which a plurality of containers 44 filled with 3 are stacked and filled.

In this device, when bubble generation is required, the storage barrel 46 is unsealed and the containers 44 are removed one by one and placed into a discharge barrel (not shown). Each time the discharge tube is filled with water, the pressure inside and outside the discharge tube is equalized, and then the compressed medicine body 43 is discharged together with the container 44 to the outside of the discharge tube.

In this case, when the water is filled in the discharge tube, the water and each container 4
The chemicals inside 4 begin to react, leading to the generation of bubbles. Therefore, once water is filled in the discharge tube, bubbles begin to occur, so it is necessary to immediately discharge each container 44 outside the discharge tube after filling with water, and the state in which water is filled inside the discharge tube is required. cannot be maintained. For this reason, only when it becomes necessary to generate a group of bubbles is the operation of filling the discharge tube with water to equalize the water pressure inside and outside the discharge tube, and then discharging each container to the outside of the discharge tube.

On the other hand, in the device (unknown) shown in FIG. 10, cylindrical unit bubble generating containers 1a with both ends open are stacked upwards via a packing 2, and after the bubble generating device is discharged outside the discharge cylinder. Immediately remove the lower presser plate 16 and connecting heel 1-17.
, the link 21 and the like are released, and at the same time the pressure equalizing plug 14 is opened. As a result, the watertightness of each unit bubble generation container 1a is lost, and the chemical compression molded body 3 in each container la reacts with water, resulting in the generation of bubbles.

[Problem to be Solved by the Invention] In the device shown in FIG. 9, each container 44 does not have a watertight structure, so when each container is placed inside the discharge tube and water is filled in the discharge tube, the water will be drained at this point. The chemicals in each container begin to react,
This results in bubble formation. For this reason, it is not possible to hold the bubble generating container 44 with water filled inside the ejection tube, so when bubbles are needed, the ejection tube is filled with water and the water pressure inside and outside the ejection tube is equalized. , requires the operation of ejecting each container to the outside of the ejection tube. Therefore, there is a problem in that it takes a long time from the time when bubble generation becomes necessary until bubble generation occurs.

On the other hand, the apparatus shown in FIG. 10 has a structure that maintains the watertightness of the bubble generating container in the discharge cylinder in order to solve the above-mentioned problems. As a result, water is kept in the discharge cylinder, and when bubbles are needed, the bubble generator can be discharged outside the discharge cylinder and bubble generation can be started. Furthermore, if airtightness is maintained under high water pressure, when the bubble generator is discharged outside the discharge tube, it will be difficult to separate each container unit due to the high water pressure. Therefore, when the bubble generator is discharged to the outside of the discharge tube, the fastening device consisting of the lower presser plate 16, the connecting heald 17, the link 21, etc. is released, and at the same time the pressure equalizing plug 14 is opened, and the high water pressure outside is released. Water flows into the bubble generator from the bubble generator, and the internal and external pressures are balanced and each container unit is separated with a small force. Here, −1−M under high water pressure as shown in No. 11M.
When the pressure equalizing tap 14 is opened and water flows into the container while water pressure is acting between the 12th
[The state shown in P+ is reached, and the internal and external water pressures 24 try to balance. Since the packing 2 is interposed on each container joint surface, the load 25 due to the water pressure corresponding to the contact area of the packing 2 remains unbalanced in the direction of the connection of each container layer. Therefore, a force sufficient to overcome this remaining small force is required to separate each container. In the bubble generator shown in Figure 10, the pressure generated by the chemical reaction within each container joint surface is expected to provide the force that overcomes the unbalanced load and separates each container. There is.

However, in this case, there are problems in that it takes time for the pressure to rise, and there is also a possibility that the internal pressure does not rise due to debris escaping from the pressure equalizing plug 14, resulting in a lack of reliability.

In addition, as shown in the figure, when water enters the joint surfaces of each container, the internal and external pressures try to balance, but the joint surfaces of each container are in a close contact state due to compression due to high water pressure. , water cannot flow in smoothly. Therefore, there is a problem in that it takes time to balance the internal and external pressures after the pressure equalizing frame is released. Conventionally, as a bubble generator, a plurality of chemicals (hereinafter also referred to as chemicals) are stacked in a container through a partition plate, the lid of the container is opened at the required depth of the sea, and the chemicals are released into the sea. and? hr1
There is a type of device that generates gas such as hydrogen gas by reaction with '.

However, with this device, it is necessary to open the lid of the drug container before use, which poses a problem in terms of operation.

A first object of the present invention is to provide a bubble generator that can instantly and reliably separate each container unit even under high water pressure and generate bubbles when the bubble generator is discharged outside the discharge cylinder. There is a particular thing.

A second object of the present invention is to provide a bubble generator that opens the container by the impact force when the bubble generator collides with the sea surface, thereby eliminating the inconvenience of manually opening the container.

[Means to solve the problem]

The first object is achieved by disposing an elastic body having a repulsive force sufficient to overcome the water pressure of the packing contact area between the laminated chemical molded bodies that react with water to generate gas.

The second purpose mentioned above is to provide a bubble generator with an elastic body that compresses when it collides with the sea surface etc. in a bubble generator equipped with a container divided into two or more parts, and to create a bubble generator with a member having this elastic body and each splittable container. This is achieved by providing a member etc. that engages with the container.

[Effect]

When the bubble generator is discharged outside the discharge cylinder under high pressure water, water flows from the outside under high water pressure into the bubble generator by the fastening means and release means, causing water to flow between the laminated surfaces of the chemical molded body. Water gets in.

In this case, the restoring force of the elastic body compressed and disposed within each container joint surface overcomes the water pressure corresponding to the contact area of the sealing packing, and each container is separated reliably and quickly. In this manner, even when the bubble generator is discharged under high water pressure, there is no time delay and the bubble generator is reliably separated into each unit bubble generating container. Therefore, the first objective of [2] is achieved.Next, when the bubble generator is put on the sea surface, the compressive action of the elastic body connects the container divided into multiple parts and the fastening member such as the camp. When the engagement is released, the container separates into multiple parts, the chemical is dispersed in the seawater, and bubbles are generated. Therefore, the second objective is achieved.

At this time, if a depth adjustment weight is installed in the chemical, the separated chemical molded bodies will settle to the required depth, and if a buoyancy regulator is contained in the chemical molded body, the bubble group will be caused to settle at a predetermined depth. Form.

It can be sealed via the A cylindrical protrusion 12 is formed in the center of the lower part of the lower cover 10, and a through hole 13 bored in the thickness direction is provided adjacent to the protrusion 12.
A pressure equalizing plug 14 is fitted into this through hole 13 .

The tightening device includes an upper presser plate 15, a lower presser plate 16, and a heald 17 connecting these. Four fixing devices 18 are provided on the upper holding plate 15 at radially symmetrical positions from the center of the disc, each of which is fixed to one end of the heel I.17.

The lower presser plate 16 has a cylindrical portion formed from a disc-shaped center, and a protrusion 1 formed on the lower lid 10 at one end of the cylindrical portion.

A safety pin 23 having a circular hole in the center is installed between them, and the adjustment screw 19 can be adjusted through this circular hole.

Next, the operation of the bubble generator configured as described above will be explained.

The bubble generator in the state shown in FIG. 1 is housed in a cylindrical chamber for several days, and the safety bin 23 is removed at the preparatory stage when bubble generation is required. At this time, the link 21 tries to spread in the radial direction of the bubble generator due to the bow tension exerted by the connecting heald 17, but the rollers 22 are locked to the inner wall of the discharge cylinder, and the watertightness of the bubble generator is maintained. . In this state, fill the discharge cylinder with water and hold it. When the bubble generator is released out of the discharge cylinder at the time when it becomes necessary to generate bubbles, the link 2 expands in the radial direction of the bubble generator and is removed from the lower presser plate 16 together with the connecting belt 17.

At this time, the lower presser plate 16 is detached from the lower cover 10 by the repulsive force of the coil spring 20, and in conjunction with this, the pressure equalizing plug 1
4 is removed from the lower cover 10. In this state, water flows in from the through hole 13 formed in the lower lid 10, passes through the through hole 5 formed in the chemical compression molded body 3, and the through hole 6 formed in the disc 4, and passes through each bubble generating container la. Reach within.

As shown in FIG. 2, the disc 4 in contact with the chemical compression molded product 3 has unevenness carved on the front surface, so that the chemical compression molded product 3 and the disc 4 can be easily bonded together under high-pressure water regardless of whether they are in close contact with each other. Water quickly enters between the two.

This uneven surface may have grooves formed in addition to normal unevenness, and the height of the unevenness is 2 mm or less, preferably 1 mm.
m Todo good. In this state, as shown in FIG.
When the external pressure 24 is balanced, the force that connects each container 1a becomes the water pressure corresponding to the contact area between the pankin 2 and the container 1a. The compressive load 25 is set so that the repulsive force of the coil springs 7 installed in a compressed state within the disc 4 is greater than the repulsive force of the coil springs 7, so that the pressure between each chemical compression molded body 3 and the disc 4 is separation occurs quickly and reliably. This...
When each bubble-generating container unit is separated in this manner, bubbles are generated vigorously from both open end surfaces of the container, and a group of bubbles is immediately formed.

FIG. 5 is a sectional view of a main part showing a second embodiment of the present invention.

In this bubble generator, a dish-shaped spring 28 made of an elastic body is installed in place of the disc 4 containing the coil spring 7 shown in FIG.

■Since the n-shaped spring 28 occupies a smaller volume than the disk 4 containing the coil spring 7, a larger amount of chemicals can be stored in a container with the same volume, so the formation of bubble groups is more reliable. becomes.

FIG. 6 is a sectional view of a main part showing a third embodiment of the present invention.

In this bubble generator, a powdered or lumpy drug 3 is stored in a layer between the disc 4 and the drug compression molded body, and the water that enters through the through holes 5 and 6 acts as a drug crystal. The drug quickly penetrates into the layer 28 and reaches the inside of the compression molded body 3. Therefore, in this bubble generator, the mounting process can be omitted without making the disc 4-1- uneven as shown in FIG.
Equipment installation is simplified.

7(A,) is a schematic side configuration diagram showing a fourth embodiment of the present invention, FIG. 7(B) is a plan view of FIG. 7(A), and FIG. 7(C) is a schematic side view of the fourth embodiment of the present invention. 1(A) is a sectional view showing the operating state of FIG. 1(A).

In this bubble generator, a cylindrical drug 31 that reacts with water to generate gas is passed through a partition device 32 into a container 3 with a semicircular cross section.
It has a structure in which a plurality of layers (six in the figure) are stacked within a 3.34-meter radius. One longitudinal end of each of the containers 33 and 34 is pivotally connected to a lid 35 via a hinge 36, respectively.

At the other end of the container 33, 34 in the longitudinal direction, there is a container camp 3.
7 is installed, and a hinge 38 pivotally attached to the side surface of the container cap 37 is locked to a locking tool provided on the container 3334, so that the container cap 37 and the containers 33 and 34 can be attached and detached. is engaged with. The inner space of the container cap 37 houses the nose 39 and the drug holding member 40, and is safely connected between the through hole provided in the container cap 37 and the through hole provided in the drug holding member 40. A pin 41 is inserted.

Each drug in FIG. 7 is formed into a cylindrical shape as shown in No. 8, and a buoyancy adjusting agent 42 is contained inside the drug, and a depth adjusting weight 43 is buried in the bottom.

Next, the operation of the fourth embodiment will be explained.

The bubble generator shown in FIG. 7 (Δ) is thrown into the sea from the ship after the safety pin 41 is removed to release the safety mechanism. At this time, since the container camp 37 acts as a weight, it falls in the state shown in FIG. 7(A) and collides with the sea surface.

Due to the impact of the device falling onto the sea surface, the hinges 39 of the container 33.3 contracted and became damaged as shown in Figure 7(C).
/I is released from the locking state with respect to the tool, and the repulsive force of the spring 39 causes the container cap 37 to close to the containers 33, 3.
Leave from 4. As a result, as shown by the imaginary line in FIG. 7(A), the container 33 has a semicircular cross section. ．． 34 are separated from each other, and the drugs 31 are individually released into the sea.

The medicine 31 released into the sea sinks while generating bubbles in the sea due to the depth adjustment weight 43 embedded in the medicine. Then, the drug 31 is dissolved at a preset depth,
Depth adjustment weight 4 (3 naturally separates from the drug 31 and falls off,
Bubbles are generated at this depth. When a group of bubbles is generated, the bubbles adhere to the surface of the drug 31 and the drug 31 tends to float. However, since the buoyancy adjusting agent 42 is preliminarily incorporated into the drug almost uniformly so as to balance the buoyancy, it is possible to form a group of bubbles at the target depth.

By adjusting the shape and weight of the depth adjustment weight 43 as shown in the figure, the sedimentation speed and sedimentation depth of the drug 31 can be controlled. In addition, depending on the selection of the buoyancy adjusting agent 42 and the amount of the buoyancy adjusting agent 42 contained in the agent 31, the buoyancy of the agent 31 when bubbles are generated can be adjusted to positive, negative, or neutral l depending on the purpose of use and the situation. ! It can be adjusted to N force.

Furthermore, since the container cap 37 is automatically separated and released from the containers 33 and 34 due to the impact of the fall, it is possible to omit the manual work of opening the container camp. Alternatively, the bubble generator shown in FIG. 7(A) may be attached to a remote drop device and dropped to a distant target point on the sea surface.

〔Effect of the invention〕

- As explained above, according to the bubble generator according to claim (1), even when the bubble generator is discharged into water under high pressure, the airtightness of each unit bubble generator can be quickly and reliably released. This can lead to the formation of bubble groups. Therefore, there is an effect of shortening the time from the time when bubbles are required until the generation of a group of bubbles. Furthermore, there is an effect that bubble groups can be reliably generated even under high water pressure.

Further, according to the bubble generating device according to claim (6), when the bubble generating device is thrown into the sea surface from, for example, a ship, the container is separated by the impact force at the time of collision with the sea surface, and a plurality of drug molded bodies are separated. Spread. Therefore, the work of manually opening the container camp etc. is omitted. Furthermore, if the drug contains an adjustment weight and a buoyancy adjustment +4, it is possible to maintain the dispersed drug molded body in water at a standard depth of 1'' and generate bubbles there.
