Description

[Technical Field]

[0001] This invention relates to a high-viscosity fire extinguishing agent viscosity recovery device that restores the viscosity of a high-viscosity fire extinguishing agent stored in a portable container by applying vibrations to the agent. [Background technology]

[0002] High-viscosity fire extinguishing agents have a high viscosity and can adhere to the surface of an object to form a layer of water, making them highly effective in preventing the spread of fire. A fire extinguishing device using such a high-viscosity fire extinguishing agent is proposed in Patent Document 1, for example.

[0003] In Patent Document 1, in order to solve the problem that a high viscosity fire extinguishing agent has a high viscosity when left at rest, and therefore a larger amount remains in the container after release than other agents, the vibrations of the pump that pumps the high viscosity fire extinguishing agent are transmitted directly or indirectly to the storage container, thereby reducing the viscosity of the high viscosity fire extinguishing agent in the storage container. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2020-151286 Summary of the Invention [Problem to be solved by the invention]

[0005] In Patent Document 1, the vibration of a pump is transmitted to a storage container when a highly viscous fire extinguishing agent is released. The pump is, for example, an air-driven pump, and one that generates large vibrations is preferred, and is attached to each fire extinguishing device. Furthermore, Patent Document 1 targets a stationary fire extinguisher, and focuses on the fact that the viscosity is high when the device is left stationary, and reduces the viscosity in order to improve the discharge efficiency. On the other hand, the present invention is directed to a small portable fire extinguisher, and the focus of the invention is completely different from that of the conventional example, so this point will be explained below.

[0006] High-viscosity fire extinguishing agents are made by mixing inorganic materials with water. If left outdoors in winter, they will freeze. Once frozen, even if they are thawed, their viscosity will fall below the specified level. However, if thawed high-viscosity fire extinguishing agents are subjected to vibration, they will regain their specified viscosity. If the agent is released after being frozen and thawed and its viscosity drops below the specified level, it will not be able to perform its intended function of adhering to the surface of the target object and preventing the spread of fire. Furthermore, the portable small fire extinguisher that is the subject of the present invention does not have a vibrating pump like that in Patent Document 1.

[0007] The present invention has been made to solve such problems, and aims to provide a high-viscosity fire extinguishing agent viscosity recovery device that restores the specified viscosity to a high-viscosity fire extinguishing agent stored in a portable container without an attached pump after it has frozen. [Means for solving the problem]

[0008] (1) The viscosity recovery device for a high-viscosity fire extinguishing agent according to the present invention recovers the viscosity of the high-viscosity fire extinguishing agent stored in a portable container by applying vibration to the high-viscosity fire extinguishing agent, The portable container is characterized in that an oscillator that vibrates when energized is disposed so as to be able to abut against the outer peripheral surface of the portable container and to be detachable.

[0009] (2) In addition, in the device described in (1) above, a cylindrical body into which the portable container is inserted is provided, and the vibrator is provided on the inner circumferential surface of the cylindrical body, The vibrator is characterized in that it is provided so as to abut against the outer peripheral surface of the portable container when the portable container is inserted.

[0010] (3) In addition, in the device described in (1) above, a mounting member is provided that is mounted on the portable container so as to cover a part or all of the circumferential surface of the portable container, and the vibrator is provided on a surface of the mounting member that faces the portable container, The vibrator is characterized in that it is provided so as to abut against the outer peripheral surface of the portable container when the mounting member is mounted on the portable container.

[0011] (4) In addition, in the device described in (1) above, a platform on which the portable container is placed is provided, and the vibrator is provided on the platform, The vibrator is characterized in that it is provided so as to abut against the bottom surface and / or lower portion of the portable container when the portable container is placed on it. [Effects of the Invention]

[0012] In the high-viscosity fire extinguishing agent viscosity recovery device of the present invention, a vibrator that vibrates when electricity is applied is arranged so that it can abut against the outer surface of a portable container in which a high-viscosity fire extinguishing agent is stored and can be attached and detached.By vibrating the portable container with the vibrator, the viscosity of the high-viscosity fire extinguishing agent, which has become less viscous due to freezing, can be restored. Furthermore, since the high-viscosity fire extinguishing agent viscosity recovery device according to the present invention is not attached to a portable container, it does not need to be provided for each portable container used, which is also advantageous in terms of cost. [Brief explanation of the drawings]

[Figure 2] FIG. 10 is an explanatory diagram of a high-viscosity fire extinguishant viscosity recovery device according to a second embodiment. [Figure 3] FIG. 10 is an explanatory diagram of a high-viscosity fire extinguishant viscosity recovery device according to a third embodiment. [Figure 4] FIG. 4 is an explanatory diagram of the high-viscosity fire extinguishant viscosity recovery device shown in FIG. 3 alone. DETAILED DESCRIPTION OF THE INVENTION

[0014] [Embodiment 1] The high-viscosity fire extinguishing agent viscosity recovery device 1 of embodiment 1 restores the viscosity of a high-viscosity fire extinguishing agent stored in a portable container by applying vibrations to the high-viscosity fire extinguishing agent, and has a vibrator 5 that vibrates when electricity is applied and is arranged so that it can abut against the outer surface of the portable container and is detachable.

[0015] Specifically, as shown in FIG. 1, it has a cylindrical body 7 into which the portable container 3 is inserted, and a vibrator 5 is provided on the inner surface of the cylindrical body 7, and the vibrator 5 is arranged to abut against the outer surface of the portable container 3 when the portable container 3 is inserted.

[0016] <Portable container> The portable container 3 has the shape of a small fire extinguisher and can be carried around by a person. The portable container 3 is provided with a hose 9 for spraying the highly viscous fire extinguishing agent contained therein, a lever 11 to be gripped by hand when spraying the highly viscous fire extinguishing agent contained therein, and the like.

[0017] <High viscosity fire extinguishing agent> As the high-viscosity fire extinguishing agent, a high-viscosity liquid having thixotropy (the property of changing from a gel to a sol when stirred or shaken) is used. For example, such a high-viscosity liquid can be prepared by adding additives containing minerals containing colloidal hydrous silicate that impart thixotropy to water or compounds made of such silicate.

[0018] <Cylindrical body> The cylindrical body 7 has a bottomed cylindrical shape with an opening 13 at the top, through which the portable container 3 can be inserted. As shown in FIG. 1, a plurality of vibrators 5 are provided on the inner peripheral surface of the cylindrical body 7, and each vibrator 5 is attached so as to abut against the inserted portable container 3 and transmit vibrations.

[0019] Since it is preferable that the vibrator 5 is pressed against the outer peripheral surface of the inserted portable container 3, the cylindrical body 7 may be provided, for example, with a vertically extending slit in part of the peripheral surface, and an elastic member such as rubber may be provided to bias the space between the slits in a direction to narrow the slit. In this way, by inserting the portable container 3 against the biasing force of the elastic member, when the insertion is complete, the cylindrical body 7 is biased in a direction that reduces the inner diameter of the entire body, and the vibrator 5 can be pressed against the outer circumferential surface of the portable container 3. This allows vibration to be transmitted more effectively.

[0020] <Vibrator> The vibrator 5 is not particularly limited in its form as long as it can transmit a predetermined vibration to the portable container 3, and examples thereof include one using an eccentric motor (ERM) or the like. The vibrator 5 vibrates when electricity is applied, but a switch for applying electricity may be provided on the cylindrical body 7. For example, if a switch is provided on the inside of the bottom of the cylindrical body 7 and the bottom of the portable container 3 activates the switch when the portable container 3 is inserted into the cylindrical body 7, vibration can be started simply by inserting the portable container 3. Also, it is preferable to set the switch to OFF when the portable container 3 is lifted and the bottom moves away from the switch, as this eliminates the need to turn the switch on and off.

[0021] According to the viscosity recovery device 1 for a high-viscosity fire extinguishant as described above, the viscosity of the portable container 3, whose viscosity has decreased due to freezing, can be restored by inserting the portable container 3 into the cylindrical body 7 and applying vibrations thereto using the vibrator 5. In the case of Patent Document 1, since a pump attached to the storage container is used, it cannot be used with a storage container that does not have a pump attached. In contrast to this, the high-viscosity fire extinguishant viscosity recovery device 1 of this embodiment can be used with a single unit for a plurality of small fire extinguishers that do not have pumps attached.

[0022] Alternatively, the high-viscosity fire extinguishing agent viscosity recovery device 1 may be provided for each portable container 3, and the portable container 3 may be stored with the device inserted.

[0023] [Embodiment 2] 2, the high-viscosity fire extinguishing agent viscosity recovery device 15 according to the second embodiment has a mounting member 17 that is mounted on the portable container 3 so as to cover part of the circumferential surface of the portable container 3 (in the example of FIG. 2, half of the side surface of the portable container 3), and a plurality of vibrators 5 are provided on the surface of the mounting member 17 that faces the portable container 3. The vibrators 5 are provided so as to abut against the outer circumferential surface of the portable container 3 when the mounting member 17 is mounted on the portable container 3.

[0024] As shown in Figure 2, the mounting member 17 has a height approximately equal to that of the portable container 3, has a front opening 19 on the front side, and is configured so that the portable container 3 can be mounted in this front opening 19.

[0025] According to this embodiment, the attaching operation is easier than the inserting operation, and therefore the highly viscous fire extinguishing agent can be attached efficiently and the viscosity of the agent can be restored before extinguishing the fire.

[0026] It is also possible to provide a switch that activates the vibrator 5 when the attachment member 17 is attached and stops the vibrator 5 when the attachment member 17 is removed. In addition, a high-viscosity fire extinguishing agent viscosity recovery device 15 may be provided for each portable container 3 and stored while attached to the portable container 3. In this case, a manual switch for activating and deactivating the vibrator 5 may be provided.

[0027] [Embodiment 3] 3, a high-viscosity fire extinguishing agent viscosity recovery device 21 according to the third embodiment has a mounting table 23 on which a portable container 3 is placed, and a plurality of vibrators 5 are provided on the mounting table 23. The vibrators 5 are provided so as to come into contact with the bottom surface and / or lower part of the portable container 3 when the portable container 3 is placed on it.

[0028] As shown in Figure 4, the mounting table 23 has a recess 25 in which the lower part, including the bottom part, of the portable container 3 can be placed, and by placing the portable container 3 in the recess 25, the vibrator 5 comes into contact with the bottom part of the portable container 3.

[0029] According to this embodiment, the portable container 3 is simply placed on the table 23, making it easier to handle. A switch may be provided so that the vibrator 5 operates when the portable container 3 is placed on the mounting table 23 and stops when the portable container 3 is removed from the mounting table 23. Moreover, the mounting table 23 may be used as a storage table, in which case a separate manual switch may be provided. [Explanation of symbols]
