Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air bubble generating device, and in particular, stores therein a chemical which generates air bubbles when released into water, and rapidly stores the bubbles under high water pressure. The present invention relates to a device suitable for generating air bubbles and a device which is easy to generate air bubbles.

[Conventional technology]

As shown in FIG. 9, an air bubble generating device that generates a group of air bubbles when released into water has an open end inside a storage outer cylinder 46 that is cut off from contact with the outside air and reacts with water. (Bubble compression) 43
There is known an apparatus in which a plurality of containers 44 each of which is filled with a plurality of are stacked and filled.

In this device, when it is necessary to generate air bubbles, the storage outer tube 46 is opened, the containers 44 are taken out one by one, and put into a discharge tube (not shown). Then, after the pressure inside and outside the discharge cylinder is equalized by filling the inside of the discharge cylinder, the chemical compression molded body 43 together with the container 44 is discharged outside the discharge cylinder. In this case, when the water is filled in the discharge cylinder, the water and the chemical in each container 44 start reacting, and bubbles are generated. Therefore, once water is filled in the discharge cylinder, air bubbles start to be generated. Therefore, it is necessary to immediately discharge each container 44 to the outside of the discharge cylinder after the water is filled. Can not be maintained. For this reason, an operation of discharging water into the discharge cylinder, equalizing the water pressure inside and outside the discharge cylinder, and then discharging each container to the outside of the discharge cylinder is performed only when it is necessary to generate the bubble group.

On the other hand, in the device (unknown) shown in FIG. 10, cylindrical unit bubble generating containers 1a having both ends opened are stacked upward via packing 2, and after the bubble generating device is discharged outside the discharge cylinder. Immediately, lower holding plate 16, connecting belt 17, link
The fastening device including 21 and the like is released, and at the same time, the pressure equalizing plug 14 is opened. As a result, the water tightness of each unit bubble generating container 1a is lost, and the chemical compression molded body 3 in each container 1a reacts with water to generate bubbles.

[Problems to be solved by the invention]

In the apparatus shown in FIG. 9, since each container 44 does not have a water-tight structure, each container is placed in the discharge cylinder, and when water is filled in the discharge cylinder, the water and the chemicals in each container react at this point. Begins to form bubbles. For this reason, since the bubble generation container 44 cannot be held in a state in which water is filled in the discharge cylinder, water is first filled in the discharge cylinder when air bubbles are needed, and after equalizing the water pressure inside and outside the discharge cylinder. In addition, an operation of discharging each container to the outside of the discharge cylinder is required. Therefore, there is a problem that it takes a long time from the time when the generation of bubbles is required to the time when the generation of bubbles occurs.

On the other hand, the device shown in FIG. 10 has a structure for maintaining the watertightness of the bubble generating container in the discharge cylinder in order to solve the above problem. As a result, the water can be held in a state in which the water is filled in the discharge cylinder, and when the air bubbles are needed, the air bubble generator is immediately discharged to the outside of the discharge cylinder to start generating the air bubbles. In addition, when the airtightness is maintained at a high water pressure, when the bubble generating device is discharged outside the discharge cylinder, it is difficult to separate each container unit due to the high water pressure. Therefore, when the bubble generator is released outside the discharge cylinder, the lower holding plate 16, the connecting belt
At the same time as the fastening device including the link 17 and the link 21 is released, the pressure equalizing plug 14 is opened, and water flows from the outside of the high water pressure toward the inside of the bubble generator, and the inside and outside pressures are balanced, and each container unit is It is separated by a small force. Here, as shown in FIG. 11, when the equalizing plug 14 is opened and water flows into the container in a state where the water pressure is acting between the upper lid 8 and the lower lid 10 under a high water pressure, FIG. The state shown in
The water pressure 24 inside and outside tries to balance. Since the packing 2 is interposed between the joint surfaces of the containers, the load 25 due to the water pressure corresponding to the contact area of the packing 2 remains in the direction of the connection of the containers without being balanced. Therefore, a force is needed to overcome this remaining small force for each container separation. In the bubble generating device shown in FIG. 10, the force that overcomes the unbalanced remaining load and causes each container to be separated is expected from the pressure generated by the chemical reaction in the coupling surface of each container. However, in this case, there is a problem that time is required until the pressure rises, and there is also a possibility that the gas escapes from the equalizing plug 14 and the internal pressure does not rise, resulting in poor reliability.

Also, as shown in the figure, when water infiltrates into each container coupling surface, the internal and external pressures are to balance,
The water cannot be smoothly flowed in because the respective container connecting surfaces are in close contact due to the compression by the high water pressure. Therefore, there is a problem in that it takes time to release the pressure equalizing plug and balance the internal and external pressures. Conventionally,
As an air bubble generator, a plurality of medicines (hereinafter, also referred to as medicines) are stacked in a container through a partition plate, the container is opened in the sea at a required depth, and the medicine is released into the sea. There is an apparatus of a type that generates a gas such as hydrogen gas by a reaction.

However, in this device, it is necessary to open the lid of the medicine container at the time of use, and there is a problem in operation and the like.

A first object of the present invention is to provide an air bubble generating device capable of instantaneously and surely separating each container unit even under a high water pressure when the air bubble generating device is discharged out of the discharge cylinder, and leading to the generation of air bubbles. It is in.

A second object of the present invention is to provide an air bubble generating device which releases the container by an impact force at the time of collision with the sea surface or the like, thereby eliminating the inconvenience of manually opening the container.

[Means for solving the problem]

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

The second object is to provide an air bubble generator having at least two or more divided containers with an elastic body that compresses at the time of collision with a sea surface or the like, and a member having the elastic body and each of the dividable containers. This is achieved by providing a member or the like that engages with.

[Action]

When the bubble generator is released outside the discharge cylinder under high-pressure water,
Water flows in from the outside under high water pressure toward the inside of the bubble generator by the fastening means and the releasing means, and water intrudes between the lamination surfaces of the chemical molded products.

In this case, the restoring force of the elastic body compressed and arranged in the joint surface of each container is superior to the water pressure corresponding to the contact area of the seal packing for sealing, and each container is separated reliably and quickly. In this way, even if the bubble generator is released under high water pressure, there is no time delay and the bubbles are reliably separated into the unit bubble generating containers. Therefore, the above first object is achieved. Next, when the bubble generator is put on the sea surface, the engagement between the container divided into a plurality of parts and the fastening member such as the cap due to the compressive action of the elastic body. Once released, the container separates into multiple pieces, the chemicals disperse in the seawater, and bubbles form. Therefore, the second
Is achieved.

At this time, if a depth adjusting weight is installed in the medicine, the separated medicine molded bodies settle down to the required depth, and if a buoyancy adjusting agent is contained in the medicine molded body, the bubbles can be formed at a predetermined depth. Form.
