Description

  The present invention relates to a fire extinguishing apparatus that can be used by a normal person, and more particularly, to a fire extinguishing apparatus suitable for initial fire extinguishing of a short-distance fire.

  In recent years, the occurrence of fires has increased as the city has become overcrowded and housing complexes have increased. Arsons are also on the rise, and suspicious fires in urban areas are also increasing. Such a fire is extinguished by an initial fire extinguishing at the time of the fire and a fire fighting operation by a fire brigade.

  In the initial fire fighting, a fire extinguisher is often used. This is because fire extinguishers must be installed in many houses and apartment buildings. However, the capacity of fire extinguishers is limited, and it is difficult to cope with many fires. In addition, a simple response from a room to a simple fire in the room is possible, but a fire extinguisher is not suitable for a fire from the outside. Fire extinguishers are limited to limited applications, such as fire from kitchen cooking oil.

  Naturally, fire fighting work by the fire brigade is most important in fire fighting. However, in the case of urban fires, it is increasingly difficult for the fire brigade to arrive at the site in a short period of time after a fire, such as traffic congestion, narrow roads, capacity that cannot respond to frequent dispatch requests, etc. It has become. By the time the fire brigade arrives at the scene, the scale of the fire will increase, and fire fighting will take longer, as well as fire damage.

  In addition, fire extinguishing work by fire brigade needs to obtain water for fire extinguishing from fire hydrants, etc., but in urban fires it is difficult to find fire hydrants or fire trucks can hardly enter narrow roads and connect fire hydrants. It may be difficult. In particular, when the fire brigade arrives, the scale of the fire is often large (since it tends to be late due to traffic congestion, road conditions, etc.), many fire hydrants can be secured. Desired. However, it is often difficult to secure a fire hydrant depending on road conditions and the distance and angle of the building. If it takes time to secure a fire hydrant, fire damage will increase.

  Thus, in today's city with many urban fires, it is important to have an initial fire extinguisher that can reduce the size of the fire and extinguish it before the arrival of the fire brigade. This is because the start of fire fighting by the fire brigade tends to be delayed due to problems such as (1) delayed arrival of the fire brigade and (2) difficulty in securing a fire hydrant or the like. On the other hand, if the initial fire extinguishing is sufficient, even if the arrival of the fire brigade is delayed, the scale of the fire can be prevented and the fire damage can be minimized.

  For modern urban fires, the importance of initial fire extinguishing is increasing, but there is a problem that general fire extinguishers cannot handle sufficient initial fire extinguishing. In addition, it is required that ordinary people in the field can be extinguished at the time of a fire rather than fire fighting professionals such as fire brigade members and fire brigade members.

  In such a situation, a technique for discharging water for fire extinguishing with a simple device instead of a fire truck (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3) or a fire extinguisher in which a fire extinguisher is enclosed is proposed. Devices for firing bullets (see, for example, Patent Document 4 and Patent Document 5) have been proposed.

  Patent Documents 1 to 3 disclose a fire extinguishing apparatus that injects water as a fire extinguishing agent. Patent Document 1 discloses a fire extinguishing apparatus that applies an electric field to stored water to form a mist state and sprays it on a fire. The spread of the fire can be suppressed by being in a spray state rather than remaining as water.

  However, the technique of Patent Document 1 has a problem that it is necessary to apply an electric field to the stored water, and the fire extinguishing apparatus becomes large. The procedure of spraying water that has been sprayed by applying an electric field is complicated for ordinary people, and it is difficult to proceed without delay. Of course, it is difficult for a general person who is not a professional firefighter to use the complex fire extinguishing apparatus disclosed in Patent Document 1 because he is mentally panicked or feels frustrated at the time of a fire.

  Moreover, the fire extinguishing apparatus disclosed in Patent Document 1 needs to be connected to a fire hydrant in order to store water in the tank. For this reason, the fire extinguisher of patent document 1 is not suitable for the general person who exists in a fire outbreak site to perform initial fire extinguishing.

  Patent Document 2 discloses a bazooka type fire extinguisher that uses a plastic tank filled with digestive juice as a cartridge. Since it has a bazooka type configuration, it can be used by ordinary people. In this respect, unlike the fire extinguishing apparatus disclosed in Patent Document 1, no large-scale operation is required. Patent Document 3 also discloses a fire extinguishing device similar to Patent Document 2.

  However, since the fire extinguishing apparatus disclosed in Patent Documents 2 and 3 is a bazooka type, it is necessary for the user to hold the apparatus on his / her shoulder, which is a heavy burden. Not suitable for long-term use. It is difficult to install and use it on the road or on the ground because there is a direction adjustment to the fire site to be ejected. Also, if the water in the polytank runs out, it is necessary to supply water to the polytank, and eventually you have to look for fire hydrants and water.

  It is difficult for ordinary people who are not fire fighting professionals such as fire brigade members and fire brigade members to find and secure fire hydrants and waterworks at the fire site, and the fire extinguishing devices disclosed in Patent Documents 2 and 3 can only be used by professionals. There is no problem. Or, the general public has a problem that only the amount of water filled in the plastic tank is used for extinguishing fire.

  Patent Documents 4 and 5 disclose fire extinguishing apparatuses that fire a fire extinguisher in which a fire extinguisher is sealed and land on the fire site to extinguish the fire. Since the fire extinguishing apparatus disclosed in Patent Documents 4 and 5 fires a fire extinguishing bullet as it is, it is necessary to destroy the fire extinguishing bullet at a fire site. The distance relationship and the positional relationship between the fire site and the fire extinguishing device vary depending on the fire situation. For example, when a fire has occurred in a building on the opposite bank such as a wide road or a river, the distance between the fire site and the fire extinguishing device must be long. Conversely, when the fire site is surrounded by buildings, the distance between the fire site and the fire extinguisher must be close.

  The external shape of the fire bomb is often made of resin or the like, but it may or may not break depending on the magnitude of the impact. For this reason, when the fire extinguishing device disclosed in Patent Documents 4 and 5 fires a fire extinguishing bullet, the fire extinguishing bullet does not break even if it hits the fire site, or it breaks before the landing, ensuring that the fire is extinguished. Some problems are not possible. It is difficult for ordinary people to fire a fire bomb to ensure that the fire bomb is destroyed at the fire site.

  Furthermore, in order to reliably destroy the fire extinguishing bullet at the time of landing, it is necessary that the distance between the fire extinguishing device and the fire site is large. Is unsuitable. There is a problem that fire extinguishing is not realized when the fire bomb does not break at the fire site.

  It is assumed that the fire extinguishing apparatus that fires fire extinguishing bullets such as Patent Documents 4 and 5 is used by fire fighting professionals such as fire brigade members and fire brigade members for fire extinguishing work where it is difficult to use a fire engine or the like.

As described above, the conventional fire extinguishing apparatus cannot solve the following problems.
(Problem 1) It is not a fire fighting professional such as a fire brigade member or a fire brigade member, and even a general person in a place where a fire has occurred cannot be handled easily.
(Problem 2) When a fire breaks out, the fire can not be extinguished in response to a short distance or a long distance.
(Problem 3) Fire hydrant and water supply must be secured, and is not suitable for initial fire fighting.
(Problem 4) Early fire extinguishment cannot suppress the expansion of the scale of fire.

  In view of the above problems, the present invention provides a digester that can reliably perform initial fire extinguishing immediately after the occurrence of a fire, even by a general person who is not accustomed to fire fighting work, by using prepared devices and members. The purpose is to do.

  In view of the above problems, the digester of the present invention is connected to a compressed air tank capable of injecting compressed air to be accommodated and compressed air injected from the compressed air tank. A pressurizing unit that applies pressure by compressed air to a fire extinguishing ball enclosing a gas, a guide tube that is connected to the pressurizing unit and that starts moving by receiving pressure from the pressurizing unit, and a guide tube Crushing means capable of crushing the outer shell of the fire-extinguishing ball moving.

  Since the fire extinguishing apparatus of the present invention is a small and simple apparatus, it can be easily held by each tenant of a building or a collective building or jointly. Furthermore, it is easy to hold a large number of fire extinguishing balls filled with a fire extinguishing agent necessary for fire extinguishing. Moreover, since the fire extinguisher of this invention only throws in and puts out a fire extinguishing ball, even a general person can use it easily. In addition, since it is possible to extinguish only with a fireball, there is no need to secure a fire hydrant or water supply.

  Together, the fire extinguishing apparatus of the present invention can perform an initial fire extinguishing at the site where a fire has occurred and immediately after that. The fire extinguishing ball can also be used as a fire extinguisher, so that it is possible to divide water discharge and throwing according to the distance from the fire site, and it is possible to cope with various fires. Furthermore, since the fire extinguisher ball can be used by hand, it can also be used other than the fire extinguishing device. As a result, the motivation to hold many fire extinguishing balls in advance is increased. For this reason, when a fire breaks out, even if a fire hydrant or water supply cannot be secured, there is little shortage of fire extinguishing agent.

  Moreover, since the fire extinguisher of this invention can also be used from the exterior of a fire scene, the danger to users, such as a fire extinguisher, decreases, and the motivation which the general person of a fire scene uses further increases. Also from this point, the initial fire extinguishing is performed quickly and the expansion of the fire scale can be prevented.

  As a result, it can be taken over by the fire brigade in an optimal state.

  (Embodiment 1)

Embodiment 1 will be described.
(Overview)
First, an overall outline of the fire extinguishing apparatus according to Embodiment 1 will be described. FIG. 1 is a schematic diagram of a fire extinguishing apparatus according to Embodiment 1 of the present invention. FIG. 1 shows the fire extinguishing apparatus as viewed from the side. The fire extinguisher 1 performs initial fire extinguishing at a fire site using a fire extinguisher ball containing contents. In addition, although it is suitable for the fire extinguisher 1 to be used for initial fire extinguishing, it is not necessarily limited to initial fire extinguishing. The right range of the present invention is not limited by the state in which the fire extinguishing apparatus 1 is used.

  The fire extinguisher 1 breaks the outer shell of the fireball containing the contents between pressurization and firing, and releases the contents from the tip, or fires the fireball containing the contents as it is from the tip. To do. When the contents have a fire extinguishing function, the fire extinguishing apparatus 1 extinguishes the fire by releasing the contents or firing a fire extinguishing ball.

  The fire extinguisher 1 includes a compressed air tank 2, a pressurizing unit 3, a guide tube 4, and crushing means 9. The compressed air tank 2 can store compressed air and can inject the stored compressed air. The pressurizing unit 3 is connected to the compressed air tank 2 and applies pressure to the fire extinguishing ball 10 by the compressed air injected from the compressed air tank 2. Of course, if a part other than the fire extinguishing ball 10 is installed in the pressurizing unit 3, the pressurizing unit 3 applies pressure to an object other than the fire extinguishing ball 10.

  The guide cylinder 4 is connected to the pressurizing unit 3 and guides the movement (injection) of the fire extinguishing ball 10. That is, the guide cylinder 4 guides the fire-extinguishing ball 10 that starts moving upon receiving pressure from the pressurizing unit 3 toward the tip of the guide cylinder 4. The fire extinguishing ball 10 receives the pressure in the pressurizing unit 3 and moves inside the guide tube 4. The crushing means 9 can crush the outer shell of the fire extinguishing ball 10 that moves along the guide cylinder 4. Since it can be crushed, it is not always crushed, but is crushed as needed (according to the user's settings). There is an injection port 42 at the tip of the guide tube 4, and the tip here refers to a region ahead of the guide tube 4 including the injection port 42. Naturally, when the outer shell of the fire extinguishing ball 10 is destroyed by the crushing means 9, the fire extinguishing ball 10 cannot reach the injection port 42, so the guide cylinder 4 does not necessarily guide the fire extinguishing ball 10 to the injection port 42. It does not mean to guide in the tip direction. When the fire-extinguishing ball 10 is fired as it is, the guide tube 4 guides the fire-extinguishing ball 10 to the injection port 42.

  The guide tube 4 has an installation position 41 and an injection port 42. Each of the installation position 41 and the injection port 42 may be formed by a cylindrical member connected to the guide cylinder 4. The installation position 41 is a position where the fire extinguishing ball 10 is installed, and is a position where the pressurizing unit 3 applies pressure to the fire extinguishing ball 10. In addition, when the fire extinguishing ball 10 is thrown from the throwing section described later, the fire extinguishing ball 10 is installed at the installation position 41.

  In addition, the fire extinguishing apparatus 1 includes a base 6 for moving and installing the fire extinguishing apparatus 1 while supporting the guide tube 4 and other elements. Since the pedestal 6 makes the fire extinguishing apparatus 1 as a whole stand stably, a user who is a general person can easily use the fire extinguishing apparatus 1 standing stably on the pedestal 6. In addition, the pedestal 6 includes wheels, so that the user can easily move the pedestal 6 to an optimum place for extinguishing the fire. In the conventional bazooka type fire extinguishing apparatus, it is necessary for the user to carry and use a heavy apparatus, but the fire extinguishing apparatus 1 according to the first embodiment has less time and effort. Of course, the pedestal 6 may not be equipped with wheels, but may be mounted on a trolley with wheels.

  Moreover, the compressed air tank 2 and the pressurization part 3 may have the connection path 5 for sending in compressed air. The compressed air tank 2 and the pressurizing unit 3 only need to be able to feed compressed air. However, depending on the overall structural characteristics of the fire extinguishing apparatus 1, a communication path 5 may be provided.

  In addition, the fire extinguisher 1 includes an operation dial 11 and an operation button 12. In FIG. 1, the compressed air tank 2 is illustrated as having an operation dial 11 and an operation button 12. However, the compressed air tank 2 may be provided in the guide tube 4 or in an operation console connected by an electric cable. May be.

  The operation dial 11 switches between a discharge mode and a firing mode, which will be described later, adjusts the pressure during firing, and adjusts the firing interval. The user operates the operation dial 11 and performs firing or the like by the operation button 12.

(Fire extinguishing by releasing contents)
Next, fire extinguishing by releasing contents will be described.

  The fire-extinguishing ball 10 moves along the arrow A inside the guide tube 4 when pressure is applied by the pressurizing unit 3. Because it receives the pressure of compressed air, it can move at high speed. When the fire extinguishing ball 10 moves along the guide tube 4, the outer shell thereof is crushed by the crushing means 9. The crushing means 9 is, for example, a protruding member. The fire extinguishing ball 10 moving at high speed in the guide tube 4 comes into contact with the protruding member, and its outer shell is crushed.

  If the outer shell of the fire ball 10 is crushed, the contents of the fire ball 10 are discharged. After the pressure is applied to the fire extinguisher ball 10, the outer shell of the fire extinguishing ball 10 is crushed, so that the content to be discharged maintains its momentum, and as shown in FIG. The contents 100 are released. In particular, when released, the contents 100 reach a target fire in a concentrated state while being diffused. The contents contained in the fire extinguishing ball 10 are at least one of a fire extinguisher, a fire extinguishing agent, a sedative, water, a dye, and a pigment. These contents are discharged from the injection port 42 by crushing the fire-extinguishing ball 10, whereby the fire can be extinguished.

  Since the fire extinguishing ball 10 is crushed inside the guide tube 4 and the contents 100 are released to the fire, the fire extinguishing ball 10 does not break when landing, and the effects of the contents 100 such as the extinguishing agent can be obtained. There is no problem. This is because the contents 100 such as a fire extinguisher and water reach a fire in that state and exhibit a fire extinguishing function. In addition, since the contents 100 are discharged by crushing after the fire extinguishing ball 10 moves through the pressurizing unit 3 and the guide cylinder 4, the contents 100 have a sufficient distance, angle, and aiming than normal water discharge. Have the advantage of reaching fire.

  FIG. 2 is an explanatory diagram showing a state in which a fire is extinguished by the release of contents in the first embodiment of the present invention. FIG. 2 shows a state in which a fire is generated in the house 50, and shows a state in which the fire extinguishing apparatus 1 releases the contents 100 with respect to the fire 60 in the house 50. The content 100 discharged from the fire-extinguishing ball 10 is discharged from the injection port 42 of the fire-extinguishing apparatus 1. Since the discharged contents 100 have the momentum of the fire extinguishing ball 10 that moves at high speed, it can reach the fire 60 with a strong momentum. Since the content 100 contains water and a fire extinguisher, the fire 60 can be extinguished. Of course, the contents 100 may be released as it is sprayed in a mist form. In this case, the content 100 is released while diffusing. Depending on the characteristics of the contents 100, the release may be a mist-like spray, a liquid launch, or a powder diffusion.

  Moreover, the fire extinguishing agent, water, etc. are discharge | released toward a fire from the injection port 42 only by throwing in the fire extinguishing ball | bowl 10 one after another. For this reason, it is not necessary to secure a fire hydrant or water supply, and the fire extinguisher 1 can be extinguished only by inserting the fire extinguishing ball 10 prepared in advance. In addition, since the fire extinguisher 1 can discharge the contents 100 with a strong momentum and a correct aim, the user does not need skill, and can also work with a certain distance from the fire 60. Due to this sense of security, fire fighters and ordinary people who are not fire fighters can perform an initial fire fighting operation using the fire extinguisher 1 immediately after a fire occurs. Of course, the fact that there is no need to secure or connect a fire hydrant or water supply can reduce the labor and burden on the user and can also ensure the optimal positional relationship between the fire 60 and the fire extinguisher 1.

  Moreover, since the fire-extinguishing ball 10 can be used as a normal fire-extinguishing bomb or a color ball for crime countermeasures, the motivation to hold the fire-extinguishing ball 10 in various places is high. For this reason, there is a high possibility that the fire extinguishing balls 10 are held in large quantities together with the fire extinguishing apparatus 1, and when the fire extinguishing apparatus 1 is used for extinguishing the fire extinguishing balls 10 that are held in succession. Would be good. This can eliminate work such as securing a fire hydrant and water supply, or drawing water from the water supply into the cartridge.

That is, the fire extinguisher 1 of the first embodiment can provide the following merits.
(1) Even ordinary people can easily operate.
(2) Since there is no need to secure a fire hydrant or water supply, fire extinguishing activities can be started immediately after a fire. The early start of fire extinguishment effectively suppresses the increase in fire scale.
(3) The risk and anxiety that the fire-extinguishing ball 10 is not crushed at the time of landing can be avoided, and the fire can be surely extinguished.
(4) Effective fire extinguishing work after arrival of fire brigades, etc., is effective and reliable by effective initial fire extinguishing by ordinary people at the fire site, and fire damage is suppressed.

  Next, the detail of each part is demonstrated.

(Compressed air tank)
The compressed air tank 2 contains compressed air and injects the compressed air into the pressurizing unit 3 at a predetermined timing. The compressed air is supplied from an air cylinder or supplied by compressing air taken in using a compressor. The compressed air tank 2 stores the compressed air supplied through such a path. The fire extinguisher 1 has an operation button 12 and an operation dial 11 in a casing that is the outer shape thereof, and the user fires the fire extinguishing ball 10 by operating the operation button 12 and the operation dial 11 (contents). In order to release the object 100, the compressed air in the compressed air tank 2 is injected. In addition, operation of the operation button 12 and the operation dial 11 demonstrated here is an example, and what is necessary is just to actually have various examples according to the specification and preparation of the digester 1.

  For example, the operation dial 11 is used to adjust the pressure value of the compressed air. The user can adjust the pressure of the compressed air in the compressed air tank 2 by adjusting the operation dial 11 according to the scale. Further, it is used to adjust the launching and firing angle of the fire extinguishing ball 10. The user uses the operation button 12 to inject the fire ball 10 from the pressure unit 3 to the guide cylinder 4.

  Since the compressed air tank 2 has a structure and a function capable of accommodating compressed air, the compressed air tank 2 has a hollow shape and a structure that can withstand pressure. For example, it is also preferable to be formed of a highly durable material such as a metal or alloy so that it can withstand pressure. As an example, it has the same material and structure as an air cylinder. Moreover, it is suitable to have the shape and magnitude | size match | combined with the shape and magnitude | size of the fire extinguishing apparatus 1 whole, and when the aspect of use is considered, it is suitable to be located behind the fire extinguishing apparatus 1.

  The compressed air tank 2 is also preferably provided with an injection port for injecting compressed air to the pressurizing unit 3. That is, the compressed air tank 2 is provided with an injection port for injecting compressed air that is instantaneously opened and accommodated based on the operation of the operation button 12 by the user (the injection port is not shown). The injection port includes a mechanism that instantaneously opens in conjunction with an operation from the operation button 12 in order to instantaneously inject compressed air and apply sufficient pressure to the fire extinguishing ball 10. Pressure is applied to the fire-extinguishing ball 10 installed in the pressurizing unit 3 by ejecting compressed air from the ejection port.

  Moreover, the compressed air tank 2 and the pressurization part 3 may be directly connected, and may be connected by the connection path 5 as FIG. 1 shows. In the case of direct connection, the compressed air injected from the injection port is directly introduced into the pressurizing unit 3 and injected onto the fire extinguishing ball 10. On the other hand, when connected by the communication path 5, the compressed air injected from the injection port is injected to the fire extinguishing ball 10 through the communication path 5. In either case, the fire extinguishing ball 10 is injected with compressed air and is given pressure by the compressed air. The presence of the communication path 5 has an advantage that the degree of freedom of the installation position of the compressed air tank 2 is increased. Although not shown, a firing valve may exist between the pressurizing unit 3 and the compressed air tank 2, and compressed air may be sent to the pressurizing unit 3 by the action of the firing valve.

  The compressed air tank 2 is supplied with compressed air through an air cylinder or a compressor after injection so that the compressed air can be continuously injected into the pressurizing unit 3. The compressed air tank 2 is removable, and it is also preferable that the compressed air tank 2 corresponding to the type of the fire-extinguishing ball 10 to be fired is attached. In addition, the compressed air tank 2 is preferably connected to the pedestal 6 together with the guide tube 4 and the like. This is because the entire fire extinguishing apparatus 1 can be stably operated by being installed by the pedestal 6.

    (Pressure part)

  The pressurizing unit 3 applies pressure by the jetted compressed air to the fire extinguishing ball 10 installed at the installation position 41. Although not shown in the figure, a firing valve is provided between the compressed air tank 2 and the pressurizing unit 3, and one fire extinguishing ball 10 is ejected from the compressed air tank 2 by this firing valve. Only compressed air is introduced into the pressurizing unit 3. For this reason, the compressed air tank 2 accommodates an amount of compressed air corresponding to the injection of one fire extinguishing ball 10. When the compressed air tank 2 discharges one ball of compressed air, the compressed air tank 2 receives a new supply of air and accommodates the compressed air.

  The pressurization unit 3 is connected to the guide cylinder 4 while being connected to the compressed air tank 2, and the fire extinguishing ball 10 is installed at the installation position 41. For this reason, it is preferable that the pressurizing unit 3 has an internal space and has a cylindrical shape in which the fire extinguishing ball 10 can move from the pressurizing unit 3 to the guide tube 4. The pressurizing unit 3 is a cylindrical member connected to the guide cylinder 4, and preferably has a structure that has an inner diameter that is the same as the diameter of the fire-extinguishing ball 10 and is sealed by the fire-extinguishing ball 10.

  The pressurizing unit 3 may further include a charging unit 7 for installing the fire extinguishing ball 10 at the installation position 41.

  FIG. 3 is a schematic diagram of the fire extinguishing apparatus according to Embodiment 1 of the present invention. The fire extinguishing apparatus 1 shown in FIG. 3 includes an insertion unit 7 for installing the fire extinguishing ball 10 at the installation position 41 (for supplying the fire extinguishing ball 10). The user supplies the fire-extinguishing ball 10 (with the contents stored therein) to the installation position 41 through the charging unit 7. The throwing unit 7 has a shutter at a portion connected to the pressurizing unit 3, and the fire-extinguishing ball 10 is thrown into the pressurizing unit 3 from the throwing unit 7 by opening the shutter. At this time, the shutter is opened by recognizing that the fire extinguishing ball has been ejected from the pressurizing unit 3, and the next fire extinguishing ball 10 is thrown into the pressurizing unit 3. Of course, the fire extinguishing ball 10 may be continuously inserted.

  The input unit 7 is connected to the casing of the pressurizing unit 3 and is connected to the internal space of the pressurizing unit 3. For this reason, when the fire extinguishing ball 10 is thrown from the throwing port 71 of the throwing unit 7, the thrown fire ball 10 moves through the internal space of the throwing unit 7 and enters the pressurizing unit 3 and stops at the installation position 41. To do. Since only the single fire extinguishing ball 10 is installed at the installation position 41, the next fire extinguishing ball 10 does not reach the installation position 41 and remains in the throwing unit 7. For example, a connecting portion between the throwing unit 7 and the pressurizing unit 3 includes a door and a shutter that can be opened and closed, and the fire extinguishing ball 10 stays in the throwing unit 7 by the door and the shutter. When the door or shutter is opened, the fire extinguishing ball 10 is supplied from the charging unit 7 to the pressurizing unit 3. That is, one fire extinguishing ball 10 is always supplied to the installation position 41 and installed. When compressed air is jetted by the pressurizing unit 3 and the fire extinguishing ball 10 is fired, the door and shutter of the throwing unit 7 are opened, and the next fire extinguishing ball 10 is supplied to the installation position 41.

  Alternatively, the installation position 41 is provided with a sensor, and when the sensor recognizes that the fire-extinguishing ball 10 is installed at the installation position 41, the pressurizing unit 3 automatically applies pressure to cause the fire-extinguishing ball 10 to move. Injection into the guide tube 4. After the injection, the door and the shutter of the charging unit 7 are opened, and the next fire ball 10 can be supplied.

  The throwing unit 7 may be provided as necessary, and may be configured such that the fire-extinguishing balls 10 are thrown manually one by one from the opening provided in the pressurizing unit 3.

  In order to effectively apply the pressure of the compressed air to be injected to the installed fire extinguishing ball 10, the pressurizing unit 3 has the internal space of the pressurizing unit 3 matched to the shape and size of the fire extinguishing ball 10. It is appropriate to have a shape and size. That is, when the fire-extinguishing ball 10 is spherical, it is preferable that the internal space of the pressurizing unit 3 has a cylindrical shape having a circular cross section. Further, the internal space of the pressurizing unit 3 is substantially equal to the diameter of the fire extinguishing ball 10 so that the injected compressed air does not leak from the periphery of the fire extinguishing ball 10 into the guide tube 4 (however, the fire extinguishing ball 10 is It is also preferable to have a gap that is movable. If it has such a shape and size, the pressurizing unit 3 can effectively apply pressure to the fire-extinguishing ball 10.

  Further, it is also preferable that the inner diameter of the pressurizing unit 3 can be changed in accordance with the change in the size of the fire extinguishing ball 10. For example, a shrink ring or the like is provided on the inner surface, and the inner diameter of the pressure unit 3 is changed in accordance with the shrinkage or expansion of the shrink ring.

In this way, the pressurizing unit 3 effectively applies pressure due to the compressed air to be injected to the fire extinguishing ball 10 installed at the installation position 41.
Here, the installation position 41 is configured so that the fire-extinguishing ball 10 can be stably installed, and the fire-extinguishing ball 10 can be fixed weakly. For example, the installation position 41 is an openable door that is formed integrally with the injection port of the compressed air tank 2, and the fire extinguishing ball 10 is fixed against the injection port. When the compressed air is injected from the compressed air tank 2, the injection port is opened, and the compressed air is injected to the fire extinguishing ball 10 at the moment when the compressed air is opened. As a result, pressure is applied to the fire extinguishing ball 10 and it can move over the guide tube 4. Further, the pressurizing unit 3 may be molded separately from the guide tube 4 or may be molded integrally. In addition, although the pressure unit 3 and the guide tube 4 are described as elements that focus on the function, they do not have to be grasped physically and visually as separate elements.

    (Guide tube)

  Next, the guide tube 4 will be described.

  The guide cylinder 4 moves the fire extinguishing ball 10 started to move by the pressure of the compressed air at the pressurizing unit 3 toward the tip. The guide tube 4 is moved toward the tip, but when the outer shell of the fire extinguishing ball 10 is crushed by the crushing means 9, the fire extinguishing ball is not fired from the injection port 42, as shown in FIGS. , The content 100 is released. Alternatively, when the outer shell of the fire extinguishing ball 10 is not crushed by the crushing means 9, the fire extinguishing ball 10 is fired as it is from the injection port 42. That is, the guide cylinder 4 guides the fire-extinguishing ball 10 toward the tip direction (may be up to the injection port 42 or in front of it).

  The guide cylinder 4 accelerates the fire extinguishing ball 10 in the process of moving the fire extinguishing ball 10 toward the tip. The fire extinguishing ball 10 is accelerated while moving the guide cylinder 4 as well as the pressure of the compressed air received by the pressurizing unit 3 to increase the speed at the time of firing. This is similar to the acceleration of bullets as they move through the gun barrel.

  Since the guide cylinder 4 guides the fire-extinguishing ball 10, the direction and angle (or reach distance) of the content 100 to be released and the direction and angle (or reach distance) of the fire-extinguishing ball 10 to be fired are determined depending on the direction and angle. Can be determined. For this reason, the guide cylinder 4 can change the angle in the vertical and horizontal directions. In some cases, the length can be expanded and contracted. This is because the reach distance of the contents 100 and the fire-extinguishing ball 10 varies depending on the length of the guide tube 4.

  For example, if the position of the fire 60 is downward with respect to the fire extinguisher 1, the tip of the guide tube 4 is directed downward. If the position of the fire 60 is upward with respect to the fire extinguishing device 1, the tip of the guide tube 4 is directed upward. Adjust to.

  Further, the guide cylinder 4 moves the fire extinguishing ball 10 at a high speed inside the guide cylinder 4 using the pressure of the compressed air applied by the pressurizing unit 3. That is, the fire extinguishing ball 10 is not only given the pressure of the compressed air by the pressurizing unit 3 but also receives the pressure of the compressed air by the guide tube 4. The compressed air injected from the compressed air tank 2 is also transmitted inside the guide tube 4 with the pressurizing unit 3 as a base point. That is, the compressed air plays a role of pushing out the fire extinguishing ball 10 from the pressurizing unit 3 to the guide cylinder 4. As the compressed air pushes the fire-extinguishing ball 10 from the pressurizing unit 3 to the guide cylinder 4, the fire-extinguishing ball 10 receives acceleration in the guide cylinder 4 and increases its speed. As a result, even when the fire extinguishing ball 10 is crushed by the crushing means 9, the content 100 that pops out has a strong momentum and can reach the fire 60 with a sufficient momentum. Of course, even when the fire-extinguishing ball 10 is fired as it is, it can reach the fire 60 with sufficient momentum.

  The guide tube 4 preferably has an internal space in which the fire extinguishing ball 10 can move. In particular, like the pressurizing unit 3, it is preferable to have an internal space corresponding to the shape and size of the fire extinguishing ball 10. For this reason, it is preferable that the guide cylinder 4 has a cylindrical shape, and the cross section of the internal space thereof preferably has a shape and size substantially equal to the shape and size of the fire extinguishing ball 10. Of course, an outer peripheral gap may be provided so that the fire-extinguishing ball 10 can move smoothly. However, it is preferable that the gap is such that the compressed air does not leak from the outer periphery of the fire extinguishing ball 10.

  The guide tube 4 is connected to a pedestal 6, and the guide tube 4 is supported by the pedestal 6. At this time, it is also preferable that an angle adjusting mechanism is provided so that the guide tube 4 can change the angle with respect to the base 6. For example, the angle adjustment mechanism is realized by a screw. The guide tube 4 is made of metal, alloy, resin or the like.

(Crushing means)
The crushing means 9 crushes the outer shell of the fire extinguishing ball 10. The crushing of the outer shell means that the contents 100 accommodated in the fire extinguishing ball 10 can be released from the injection port 42. Since the crushing means 9 has only to crush the outer shell of the fire extinguishing ball 10, the crushing means 9 applies at least one of an electrical impact, a physical impact, and a chemical impact to the fire extinguishing ball 10 that moves on the guide tube 4. Due to these impacts, the crushing means 9 crushes the outer shell of the fire extinguishing ball 10.

  In the electric shock, for example, an electric current or plasma is applied to the moving fire extinguishing ball 10 to crush the outer shell. A physical impact crushes the outer shell by a physical action such as a member or pressure. The chemical impact breaks the outer shell by discharging a solvent that melts the outer shell of the fire extinguishing ball 10. In any of an electric shock, a physical shock, and a chemical shock, the fire ball 10 crushes its outer shell during movement. Therefore, the contents 10 accommodated from the crushed fire ball 10 are As shown in FIG.

  As an example of a physical impact, the crushing means 9 has a protruding member that can come into contact with a fire extinguishing ball 10 that moves on a guide cylinder 4 as shown in FIGS. 1 and 3. The protruding member is made of a hard material such as resin, metal, alloy, or the tip is sharpened or sharpened, so that the protruding member only comes into contact with the moving fire extinguishing ball 10, and the crushing means 9 Can crush the outer shell of the fire extinguishing ball 10.

  FIG. 4 is a perspective view of the protruding member according to Embodiment 1 of the present invention. The protruding member 91 has a shape in which the tip 92 is sharp (sharp). The protruding member 91 is mounted in, for example, a hole 47 provided in the guide cylinder 4. The protruding member 91 can move up and down in the hole 47 as shown by an arrow A. When the protruding member 91 is moving upward through the hole 47, the tip 92 of the protruding member 91 does not reach the inside of the guide tube 4 or does not reach the fire extinguishing ball 10 even if it reaches. On the other hand, when the protruding member 91 moves down the hole 47, the tip 92 contacts the fire extinguishing ball 10 that moves along the arrow B inside the guide tube 4. Since the tip 92 is sharp, the protruding member 91 can crush the fire-extinguishing ball 10.

  By increasing or decreasing the amount of protrusion of the protruding member 91 with respect to the hole 47, crushing of the fire extinguishing ball 10 can be adjusted.

  Moreover, the guide cylinder 4 can change the attachment position of the protrusion member 91 by providing the some hole 47. FIG. In particular, when the protruding member 91 is attached to the hole 47 on the side close to the tip of the guide cylinder 4, when attached to the hole 47 near the center of the guide cylinder 4, when attached to the hole 47 on the near side of the guide cylinder 4, etc. If it divides into two, the position where the protrusion member 91 crushes the fire extinguishing ball | bowl 10 can be switched. For example, the attachment position of the protruding member 91 may be determined according to the case where the content 100 is desired to be more converged and released or the content 100 is desired to be diffused and released.

  Alternatively, the crushing means 9 may use the fact that the pressure applied by the pressurizing unit 3 exceeds the durability of the outer shell of the fire extinguishing ball 10. The pressurizing unit 3 applies pressure and injects the fire extinguishing ball 10 into the guide tube 4. At this time, since the pressurizing unit 3 applies pressure by compressed air, force due to the pressure is applied to the outer shell of the fire extinguishing ball 10. If this force is large, the outer shell may be crushed. Since the outer shell is formed of resin or the like, the outer shell is crushed during movement in the guide tube 4 when a force exceeding durability is applied. As a result, the contents 100 are discharged from the injection port 42 with a high force.

  Specific examples of these crushing means 9 are merely examples, and various members and methods that can crush the outer shell while moving the guide tube 4 are included.

  Further, when the protruding member 91 is retracted to the extent that it does not reach the outer shell of the fire extinguishing ball 10, the outer shell of the fire extinguishing ball 10 is not crushed, so that the fire extinguisher 1 can fire the fire extinguishing ball 10 as a fire extinguishing bullet. The crushing means 9 can crush the outer shell of the fire extinguishing ball 10 while it is moving, and is not always intended to crush.

  As will be described later, the fire extinguisher 1 optionally includes a discharge mode in which the outer shell of the fire extinguishing ball 10 is crushed and the contents 100 are discharged from the injection port 42, and the fire extinguishing without breaking the outer shell of the fire extinguishing ball 10 The ball 10 is provided so that it can be switched to a launch mode in which the ball 10 is fired from the exit 42 as it is.

  The content 100 is discharged from the injection port 42 by the crushing means 9 when this option is present when the discharge mode is being washed. When this option is not provided in the first place, if the crushing means 9 is ready to crush the outer shell, the content 100 popping out by crushing is discharged from the injection port 42.

  In addition, since it is calculated | required that the content 100 jumps out from the injection port 42 vigorously by crushing the outer shell of the fire extinguishing ball | bowl 10 inside the guide cylinder 4, the crushing means 9 comprised by the protrusion member 91 etc. is guidance. It is preferable that the tube 4 is provided at a position close to the tip side. The speed of the fire-extinguishing ball 10 is accelerated, and the contents 100 (liquid fire extinguishing agent, water, etc.) are vigorously ejected from the injection port 42 by being crushed at the tip side that has just jumped out of the injection port 42 of the guide tube 4. This is because especially if) is released.

  As described above, the fire extinguisher 1 in Embodiment 1 can easily extinguish a fire by crushing the fire extinguishing ball 10 inside the guide tube 4 and releasing the contents 100. In particular, the fire extinguisher 1 is neither large-scale nor complicated, and it is not necessary to hold it, so it is easy for ordinary people at the fire site to use. In addition, since it is not necessary to secure a fire hydrant or water supply, fire extinguishing can be started immediately after a fire occurs. Moreover, since the fire-extinguishing ball | bowl 10 can be used also as a fire extinguishing bullet, it is easy to hold and store. It is also possible to use the fire extinguishing ball 10 owned by a building other than the fire-generating building. Together, ordinary people can immediately enter fire fighting activities, improving the accuracy of initial fire fighting and preventing the spread of fire damage.

  In addition, the fire extinguishing apparatus 1 according to Embodiment 1 is preferably used not only by ordinary people present at the site where a fire has occurred, but also by firefighters and firefighters who have rushed. When it is difficult for a fire brigade rushing for the initial fire fighting to find a fire hydrant, the fire extinguisher 1 is first used to perform the initial fire fighting.

  (Embodiment 2)

  Next, a second embodiment will be described.

  The situation of a fire or fire site where it is suitable to crush the outer shell of the fire ball 10 and release the contents 100, and the situation of a fire or fire site where the fire ball 10 is suitable to be fired and landed There is. For this reason, the fire extinguisher 1 not only assumes that the outer shell of the fire extinguishing ball 10 is crushed as in the first embodiment, but also switches between the release of the contents 100 and the launch of the fire extinguishing ball 10. It is also possible to make it possible. In the second embodiment, switching is performed between a discharge mode in which the outer shell of the fire extinguishing ball 10 is crushed and the contents 100 are released, and a firing mode in which the outer shell of the fire extinguishing ball 10 is fired without being crushed. The fire extinguishing apparatus 1 will be described.

  FIG. 5 is a schematic diagram of a fire extinguishing apparatus according to Embodiment 2 of the present invention. The fire extinguisher 1 includes mode switching means for switching between a discharge mode and a launch mode. As shown in FIG. 5, the content 100 is discharged in the release mode, and the fire extinguishing ball 10 is fired in the launch mode. The switching means is realized by the operation dial 11, and the operation dial 11 switches between the discharge mode and the launch mode. For example, the operation dial 11 includes a mode switching switch, and the fire extinguishing apparatus 1 realizes mode switching by switching the switch.

  For example, when the discharge mode is selected by the mode switching means, the protruding member 91 protrudes from the guide tube 4 to the extent that it can contact the moving fire extinguishing ball 10. Conversely, when the launch mode is selected by the mode switching means, the protruding member 91 moves to a position in the guide tube 4 where it cannot contact the fire extinguishing ball 10. Alternatively, when the crushing means 9 uses the pressure level in the pressurizing unit 3, the pressure in the pressurizing unit 3 is large and the mode is switched when the discharge mode is selected by the mode switching unit. When the firing mode is selected by the means, the pressure at the pressurizing unit is reduced. By such switching, it is determined whether the outer shell of the fire extinguishing ball 10 is crushed or not.

  When the firing mode is selected, the crushing means 9 does not crush the outer shell of the fire extinguishing ball 10, and the fire extinguishing ball 10 is launched as it is from the injection port 42. When the fire-extinguishing ball 10 is fired as it is from the injection port 42, the fire-extinguishing ball 10 reaches the fire site. Due to the impact at the time of landing, the outer shell of the fire extinguishing ball 10 is crushed and the contents 100 accommodated therein can spread and extinguish at the fire site.

  If the fire site is in a state close to the fire extinguishing apparatus 1, even if the fire-extinguishing ball 10 lands, the impact is weak and it may not be crushed. In such a case, as described in the first embodiment, it is preferable that the outer shell of the fire extinguishing ball 10 is crushed in the guide tube 4 and the contents 100 are discharged. In particular, in the case of a short-distance fire, the content is radiated from the beginning rather than spreading the content for the first time at the time of landing, because the fire extinguishing efficiency is higher. This is especially true when the contents are liquid fire extinguishers or water.

  On the other hand, the fire site may be far from the fire extinguishing apparatus 1. This is the case when the location of the fire site or the user is afraid of a fire and cannot get close to the fire site. In such a case, it is better to fire and extinguish the fire-extinguishing ball 10 at a distant fire site than to discharge the contents 100 such as water and fire extinguishing agent from the injection port 42. Corresponding to such a case, the fire extinguisher 1 has an option that allows the fire-extinguishing ball 10 to be fired and landed on the fire site in the launch mode.

  FIG. 6 is an explanatory diagram illustrating fire extinguishing in the firing mode according to Embodiment 2 of the present invention. When the firing mode is selected, the fire extinguisher 1 (injection port 42) fires the fire extinguishing ball 10. The fire extinguisher 1 fires a fire extinguishing ball 10 toward the fire 60 generated in the residence 50. The fire-extinguishing ball 10 lands on the fire 60 and is crushed by the impact. By crushing the fire-extinguishing ball 10, the content 100 spreads around the fire 60 and extinguishes.

  When the fire mode is selected, the fire extinguisher 1 is in a position where the protruding member 91 does not contact the fire extinguishing ball 10 and can fire the fire extinguishing ball 10 as it is. Moreover, the fire extinguishing apparatus 1 adjusts the pressure in the pressurizing unit 3 so that the fire-extinguishing ball 10 is reliably crushed at the time of landing. For example, when exiting the injection port 42, the speed of the fire extinguishing ball 10 is adjusted to become maximum.

  If the fire extinguishing apparatus 1 also has a function of firing the fire extinguishing ball 10 as it is, the motivation for storing the fire extinguishing ball 10 as a fire extinguishing bullet increases. This is because, in some cases, the fire extinguisher 1 can be mainly used to fire a fire extinguishing ball 10 as a fire extinguishing bullet. As a result, a large amount of fire extinguishing balls 10 are stored in buildings, residences, buildings, and the like that can become fire sites, and the degree of achievement of initial fire extinguishing using the fire extinguishing device 1 is further increased.

As described above, the fire extinguisher 1 can realize fire extinguishing in accordance with the fire environment by the mode switching means.
In addition, it is also suitable for the throwing part 7 to be able to throw in a fire extinguishing ball 10 having a diameter larger than the inner diameter obtained in a state where the projecting member 91 projects and a fire extinguishing ball having a diameter smaller than the inner diameter. is there. When the fire extinguishing ball 10 having a diameter larger than the inner diameter is inserted, the outer shell of the fire extinguishing ball 10 that moves along the guide tube 4 is crushed by the protruding member 91. As a result, the content 100 is discharged from the injection port 42. When the fire extinguishing ball 10 having a diameter smaller than the inner diameter is thrown in, the fire extinguishing ball 10 that moves along the guide tube 4 does not come into contact with the protruding member 91, and thus the fire extinguishing ball 10 is launched as it is from the injection port 42. In this case, land on the fire and extinguish it.

  Thus, it is possible to switch between a discharge mode for discharging the contents 100 and a launch mode for firing the fire-extinguishing ball 10 as it is, depending on the diameter of the fire-extinguishing ball 10 to be inserted, without depending on the mode switching means.

  Since the fire extinguishing apparatus 1 according to the second embodiment can switch between the emission mode and the discharge mode, it is possible to perform an optimum fire extinguishing activity according to the environment and situation of the fire or the fire site. Due to such flexibility, the spread of the fire extinguishing apparatus 1 and the fire extinguishing ball 10 is increased, and initial fire extinguishing at a fire site where it is difficult to secure a fire hydrant and water supply becomes easier.

  (Embodiment 3)

Next, Embodiment 3 will be described.
The fire extinguisher 1 in Embodiment 3 has a device for improving the movement of the digestion ball 10 in the guide tube 4 and the release of the contents 100.

(groove)
It is also preferable that the guide tube 4 has a groove on the inner side (inner periphery). The groove diffuses or converges the content 100 that is released when the outer shell of the fire extinguishing ball 10 is crushed. FIG. 7 is an inner surface view of the guide tube in the third embodiment of the present invention. The guide tube 4 has a groove 48 on its inner periphery. Since the groove 48 can be oriented, it guides the content 100 that pops out when the outer shell of the fire extinguishing ball 10 is crushed inside the guide tube 4. As shown in FIG. 7, since the grooves 48 are gathered from the base of the guide tube 4 toward the tip (toward the injection port 42), the contents 100 can be easily converged.

  When the groove 48 converges the content 100, the content 100 discharged from the injection port 42 while maintaining the momentum is discharged in a converged state. For example, in the case of a pinpoint where the fire is very small, the content 100 such as water and extinguishing agent converges and is released, thereby improving the fire extinguishing efficiency.

  In addition, when the groove 48 has a shape that diffuses toward the tip of the guide tube 4, the content 100 that pops out due to the crushing of the fire-extinguishing ball 10 is discharged from the injection port 42 so as to diffuse. The Due to the release of the diffusion, the discharge 100 can be uniformly exposed to a wide range. For example, for a wide fire, it is preferable that the content 100 is diffused and released in this way.

  The shape of the groove 48 is an example, and by having various shapes, convergence and diffusion are realized in the discharge of the content 100. As a result, the contents 100 can be released according to the characteristics of the fire.

  In addition, a slidable cover may be provided on the surface of the groove 48. When the cover moves, the groove 48 is covered or exposed. When this cover covers the groove 48, the groove 48 is not exposed to the inner periphery of the guide tube 4, and the groove 48 does not perform its function. Conversely, when the cover slides to expose the groove 48, the groove 48 can exhibit its function. Since the function of the groove 48 is necessary / unnecessary depending on the characteristics of the fire and the environment of the fire site, it is also preferable that the exposure of the groove 48 is switched by the cover.

  Further, the guide tube 4 may switch between diffusion and convergence by changing the exposed shape of the groove 48 by sliding the cover.

(Air passage)
In addition, the guide tube 4 is preferably provided with an air passage along the moving direction of the fire extinguishing ball 10. The pressurizing unit 3 feeds the compressed air from the compressed air tank 2 to the air passage to make the fire-extinguishing ball 10 move smoothly. FIG. 8 is a side view of the guide tube in the third embodiment of the present invention.

  The guide tube 4 includes an air passage 45. The air passage 45 is formed along the moving direction of the fire extinguishing ball 10 in the guide tube 4. The air passage 45 is a groove-like recess provided in the inner wall of the guide tube 4, and even when the inside of the guide tube 4 is filled with the fire extinguishing ball 10, air can escape through the air passage 45. For this reason, the friction between the fire extinguishing ball 10 and the inner surface of the guide tube 4 is reduced, and the movement of the fire extinguishing ball 10 becomes easy.

  Since the air passage 45 is connected to the guide tube 4, an air flow is generated around the fire ball 10 when the fire ball 10 moves through the guide tube 4. The guide cylinder 4 has an internal space, and the fire extinguishing ball 10 moves in this internal space. At this time, when the fire-extinguishing ball 10 is completely fitted in the internal space (when the diameter of the fire-extinguishing ball 10 is substantially the same as the diameter of the internal space), the stability of the movement of the fire-extinguishing ball 10 in the guide tube 4 is stable. However, the fire-extinguishing ball 10 is difficult to move due to friction with the internal space.

  On the other hand, when the diameter of the internal space of the guide tube 4 is sufficiently larger than the fire extinguishing ball 10, the movement of the fire extinguishing ball 10 is not hindered, but the directionality in the movement of the fire extinguishing ball 10 is not uniform, and the fire extinguishing ball 10 There is a problem that it becomes difficult to control the launch direction.

  Even when the air passage 45 is completely fitted in the guide tube 4, the air passage 45 forms an air passage around the fire extinguishing ball 10, so that friction between the fire extinguishing ball 10 and the inner wall of the guide tube 4 can be reduced. In addition, since the air passage 45 transports compressed air, it helps the movement of the fire-extinguishing ball 10 within the guide tube 4. For this reason, the movement of the fire extinguishing ball 10 is promoted by the air passage 45 while the diameter of the internal space of the guide tube 4 and the diameter of the fire extinguishing ball 10 are substantially the same. As a result, the guide cylinder 4 can accurately control the firing direction while promoting the movement of the fire-extinguishing ball 10.

Note that one or more air passages 45 may be provided inside the guide tube 4.
(attachment)

  It is also preferable that the guide tube 4 further includes an attachment that gives friction to the fire extinguishing ball 10 in the internal space. The fire extinguisher 10 crushes the outer shell of the fire extinguishing ball 10 inside the guide tube 4 and releases the contents 100. As described in the second embodiment, the fire extinguishing ball 10 is fired as it is depending on the characteristics of the fire. Sometimes. In this case, by providing the attachment, the trajectory control of the fire-extinguishing ball 10 to be fired becomes easy.

  FIG. 9 is a side view of a guide tube provided with an attachment according to Embodiment 3 of the present invention. FIG. 10 is a front view of a guide tube provided with an attachment according to Embodiment 3 of the present invention. In any of the drawings, the guide tube 4 includes an attachment 8 that gives friction to the fire extinguishing ball 10 inside thereof. The attachment 8 comes into contact with the surface of the fire-extinguishing ball 10 moving on the guide cylinder 4 and gives friction to the fire-extinguishing ball 10. Due to this friction, the fire extinguishing ball 10 is appropriately rotated, and the fire extinguishing ball 10 accurately reaches the target landing position.

  When the spherical fire extinguishing ball 10 is launched and thrown, if it has no rotation at all, it will be dragged by gravity and falls downward. On the other hand, when the fire-extinguishing ball 10 is rotating, it has resistance to gravity and air resistance, so that the fire-extinguishing ball 10 can easily reach the target landing position without falling down.

  The attachment 8 includes a friction body 83 that can contact the surface of the fire extinguishing ball 10, and convex portions 84 and 85 that contact the surface of the fire extinguishing ball 10 provided on the surface of the friction body 83 at at least two places. The shape and structure of the convex portions 84 and 85 are as shown in FIG. Further, the attachment 8 is attached to the internal space of the guide tube 4 by an attachment 81.

  The attachment 8 causes the fire extinguishing ball 10 to rotate by bringing the extinguishing ball 10 into contact with the surface by the friction body 83 and the convex portions 84 and 85. This will be described with reference to FIG. The fire-extinguishing ball 10 starts moving by receiving the pressure of compressed air by the pressurizing unit 3 (not shown). The fire extinguishing ball 10 that has started this movement enters the inside of the guide tube 4. The fire extinguishing ball 10 at this position is shown as a fire extinguishing ball 10F in FIG. The fire-extinguishing ball 10 advances inside the guide tube 4 by the initial speed and the continued pressure of compressed air.

  The fire extinguishing ball 10 that has advanced inside the guide tube 4 eventually approaches the injection port 42. An attachment 8 is provided in front of the injection port 42. The fire extinguishing ball 10 is in contact with at least a part of the friction body 83 and the convex portions 84 and 85 of the attachment 8. The position of the fire extinguishing ball 10 at this time is shown as a fire extinguishing ball 10G. The fire-extinguishing ball 10 receives friction by coming into contact with the friction body 83 and the like, and the fire-extinguishing ball 10 is ejected from the injection port 42 while rotating by the friction. As a result, the fire-extinguishing ball 10 can reach the landing position while rotating. The fire-extinguishing ball 10 is thrown while rotating, so that it is not easily affected by air resistance or gravity, and the fire-extinguishing device 1 can easily reach the target position. This is similar to a baseball that flies straight while rotating.

  Each of the two convex portions 84 and 85 preferably has a contact surface along the moving direction of the fire extinguishing ball 10. In addition, each of the two convex portions 84 and the convex portions 85 is preferably substantially parallel. By having such a structure, the convex portions 84 and 85 can give the fire extinguishing ball 10 rotation in a predetermined direction. For example, when the attachment 8 is attached to the upper part of the guide tube 4, the convex portions 84 and 85 can give a vertical rotation to the fire extinguishing ball 10. Since the vertical rotation has a resistance against gravity and air resistance, the fire-extinguishing ball 10 is less likely to fall and can reach the target landing position accurately.

  Further, when the attachment 8 is attached to either the left or right of the guide tube 4, the fire-extinguishing ball 10 is laterally rotated. By this horizontal rotation, the fire-extinguishing ball 10 can reach the landing position while curving.

  For example, in a state where there is an obstacle in which the position where the fire extinguishing device 1 can be installed and the landing position cannot be connected straight, it is also appropriate to throw the fire extinguishing ball 10 by such a curve. For example, even when there is a building or a parked car in front of the fire site, the fire-extinguishing ball 10 can reach the landing position while avoiding these obstacles.

  Further, the number of rotations and the amount of rotation of the fire extinguishing ball 10 are determined by the frictional force applied by the attachment 8. This frictional force is determined by the amount of contact between the friction body 83 and the convex portions 84 and 85 and the fire extinguishing ball 10. This contact amount is determined by how much force (distance) the friction body 83 is pressed against the fire extinguishing ball 10. For this reason, it is also preferable that the attachment 8 further includes an adjustment member 82 that allows the friction body 83 to move up and down with respect to the fire extinguishing ball 10 (with respect to the internal space of the guide tube 4).

  FIG. 10 shows the attachment 8 including the adjustment member 82.

  The adjustment member 82 protrudes to the outside of the guide tube 4, and the attachment 8 is installed inside the guide tube 4 via the attachment 81. The adjustment member 82 can be rotated by a screw, and the attachment 81 is moved back and forth by this rotation to move the friction body 83 up and down. When the friction body 83 enters deeper into the internal space of the guide tube 4, the friction body 83 comes into stronger contact with the fire-extinguishing ball 10, so that strong friction is applied to the fire-extinguishing ball 10. Due to this strong friction, the fire-extinguishing ball 10 can be rotated at a higher rotational speed. The greater the number of revolutions, the stronger the angle in straight throwing and curves.

  On the other hand, when the friction body 83 moves in the direction away from the fire extinguishing ball 10 in the internal space of the guide tube 4, the friction body 83 gives a weak friction force to the fire extinguishing ball 10. As a result of the weak frictional force, the number of revolutions of the fire extinguishing ball 10 is reduced.

  By the adjustment member 82 that moves the friction body 83 up and down, the attachment 8 can adjust the frictional force applied to the fire-extinguishing ball 10 and can adjust the rotation speed of the fire-extinguishing ball 10.

  The friction body 83 has a predetermined width and length, and has a base material serving as a substrate and a contact surface that comes into contact with the surface of the fire extinguishing ball 10. The base material is formed of a metal, resin, or alloy that is connected to the fixture 81. The contact surface is made of a material such as rubber or felt, or an absorbent synthetic material such as neoprene sponge. Moreover, the convex part 84 and 85 can be formed in the contact surface affixed on the surface of this base material because a part of base material rises. As a result, the friction body 83 has an integral configuration with the convex portions 84 and 85, and the attachment 8 can apply friction to the fire extinguishing ball 10 by this integral configuration.

  Only one of the convex portions 84 and 85 may be provided. A plurality of attachments 8 may be attached to the guide tube 4.

  As described above, when the guide tube 4 includes the attachment, the fire extinguisher 1 can give an appropriate rotation to the fire extinguishing ball 10, and the fire extinguishing ball 10 is accurately thrown at a target landing position. As a result, the fire-extinguishing ball 10 containing the contents necessary for extinguishing and calming down such as fire and terrorism can be appropriately launched to the target landing position.

  As described above, by providing the attachment, the firing of the fire-extinguishing ball 10 in the firing mode is sufficiently controlled.

  In addition, the usage method which uses the fire extinguishing apparatus 1 is also contained in this invention.
