Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The fire extinguisher training device according to the present invention relates to a fire extinguisher training device capable of injecting water by the same operation as the fire extinguisher and practicing how to use the fire extinguisher and refilling the water. It is a thing.

[0002]

[Prior art]

 In the event of a fire, a fire extinguisher is commonly used as an initial fire extinguisher. However, since this fire extinguisher is rarely used except when a fire occurs, it is the actual situation that a person who has no experience of using it should use it for the first time when a fire occurs. For this reason, when the fire extinguisher is actually used in an emergency situation, it may not be possible to operate it smoothly, miss the chance of initial fire extinguishment, and cause a catastrophe.

Therefore, it is desirable to be able to easily carry out training for actually using the fire extinguisher, but in the actual fire extinguisher, the fire extinguishing agent cannot be easily refilled once used, and replacement is expensive. It will be Therefore, there was a need for a device for training the use of a fire extinguisher, that is, an inexpensive fire extinguisher training device capable of easily refilling the content liquid. Therefore, there has been proposed a fire extinguisher training device that has a structure in which water that can be easily obtained is used as a content and can be refilled, and that can spray water as the content by the same operation as a fire extinguisher. It was

FIG. 4 shows a conventional configuration example of such a fire extinguisher training apparatus. As shown in the figure, the fire extinguisher training device 10 has a bottomed cylindrical body 12, and side walls thereof are provided with an injection hole 12a for injecting water and compressed air and an injection pipe 14. . The inside of the cylindrical main body 12 has a simple hollow structure, and water can be injected from the injection pipe 14. Furthermore, compressed air can be injected as a drive source for making it possible to inject the water to the outside by the same operation as a fire extinguisher.

An upper lever 16 and a lower lever 18 are provided on the upper portion of the cylindrical body 12, and in a normal state, the safety pin 20 cannot operate them. An air pressure display meter 22 for displaying the air pressure inside the cylindrical main body 12 is provided at the upper position. The display surface 22a of the air pressure indicator meter 22 is formed to be substantially vertical to the vertical axis direction of the tubular body 12 when the tubular body 12 is installed with the bottom portion 12b facing down. . Further, a hose 24, which is an internal water injection passage, and a nozzle 26 provided at the tip of the hose 24 are attached to an upper position of the cylindrical main body 12.

The compressed air after the water injection is injected from the injection pipe 14, and the air pressure is adjusted so that the pressure inside the cylindrical main body 12 is about 8 atm. When the internal filling work is completed in this way, the safety pin 20 is removed, and the upper lever 16 is gripped so as to rotate in the direction of arrow 100 to open the valve of the valve opening / closing mechanism 30, and the hose 24 is opened by compressed air. Water can be vigorously sent to the nozzles 26 to inject water. In this way, water can be jetted by the same operation as a normal fire extinguisher, and easy fire extinguisher use training is possible. With such a fire extinguisher training device, water can be refilled repeatedly, so it is possible to practice using a fire extinguisher repeatedly without having to replace the entire device.

[0007]

[Problems to be solved by the device]

 In the fire extinguisher training device 10 as described above, the filling space 200 of compressed air must be properly secured in order to obtain a sufficient pressure for injecting water. For that purpose, it is necessary to set the appropriate amount of water to fill. However, providing the cylindrical body 12 itself with a scale structure that allows the amount of water to be seen from the outside complicates the configuration of the apparatus, complicates the manufacturing process, and increases the cost.

Therefore, the injection pipe 14 is provided so that the amount of water can be set based on the position of the injection pipe 14. However, when the fire extinguisher training device 10 having the above-described conventional injection pipe 14 is used, it is very difficult to pour water in a normal state in which the bottom portion 12b of the tubular body 12 is set up. Therefore, as shown in FIG. 5, the cylindrical main body 12 is laid down so that the injection pipe 14 is directed upward, and water is injected into the inside by using the funnel 28 or the like.

Then, water is injected to an appropriate position shown by a broken line X in FIG. 4, but the adjustment of the water amount is extremely troublesome. That is, as described above, the funnel 28 is used to inject water while the tubular main body 12 as shown in FIG. 5 is laid down. If it is too small, it is necessary to lay it down again to inject water, and if it is too much, it is necessary to perform the operation of draining water from the injection pipe 14. This is because if the amount is too small, the air pressure becomes insufficient, and if the amount is too large, the injection pipe 14 is blocked when the compressed air is injected with the tubular body 12 standing. This is to prevent it.

Further, after the injection of water is completed, compressed air is injected, but in this case, it is necessary to inject the compressed air while monitoring the internal air pressure until an appropriate pressure is reached. Therefore, the operation is performed while confirming the internal pressure while looking at the display surface 22a of the air pressure display meter 22. However, since the display surface 22a is formed in a substantially vertical state as described above, there is a problem in that the display is very difficult to see when performing an air injection operation with an air injection device for a bicycle. Therefore, it is necessary to interrupt the air injecting operation and confirm the display surface 22a, or perform an air injecting operation while another person confirms the display surface 22a.

The present invention has been made to solve the inconvenience of the conventional fire extinguisher training device, and its object is to inject an appropriate amount of water or to inject internal air pressure during air injection. (EN) Provided is a fire extinguisher training device in which the visual recognition of the fire extinguisher is made easy by making it extremely easy with a simple structure.

[0012]

[Means for Solving the Problems]

 In order to achieve the above object, a fire extinguisher training apparatus according to claim 1 is configured such that a bottomed cylindrical main body that can be sealed and a side wall of the cylindrical main body are formed at a predetermined position so as to inject water and compressed air therein. Possible injection holes, water injection mechanism that injects water injected into the tubular body to the outside by the pressure of the compressed air also injected, and air pressure inside the tubular body attached to the tubular body is displayed. In a fire extinguisher training device equipped with an air pressure display meter for external display on the surface, a tube portion protruding outward from the side wall of the tubular body is provided in the injection hole, and the shape of the tube portion is With the bottom of the tubular body installed downward, first, the tubular body is projected almost at right angles to the vertical axis direction and bent upward at an intermediate position to open the tip opening upward. It is characterized by

Further, in the fire extinguisher training apparatus according to a second aspect, the display surface is provided so that the pneumatic pressure display meter can be easily visually recognized from above in a state where the pneumatic pressure display meter is installed with a bottom portion of the tubular main body facing downward. It is characterized in that it is provided so as to be inclined upward by a predetermined angle with respect to the vertical axis direction of the cylindrical main body.

[0014]

[Action]

 According to the fire extinguisher training apparatus according to the above-mentioned claim 1, the tubular main body for injecting water and air is installed with the bottom portion downward, that is, the tip opening of the pipe portion is directed upward in a standing state. It is bent and formed. Therefore, it is possible to easily inject water with the tubular body upright, and when water is being injected from the pipe part using a funnel, etc., when the amount of water has increased to an appropriate amount. The position of the water surface can be easily confirmed from the tip opening of the pipe. Therefore, the water injection operation can be performed with the tubular main body kept upright, and the appropriate amount of water can be visually confirmed to complete the injection work. Therefore, it is possible to eliminate the troublesome work of repeating the operation of laying down or standing up the tubular body as in the conventional example.

Further, according to the fire extinguisher training apparatus according to the second aspect, when the compressed air is injected after the water injection work is completed, the display surface of the air pressure display meter is inclined and slightly upward. The air injection operator can easily visually check the display surface while performing the air injection work. That is, when the worker is performing the air injection operation while standing up, the display surface of the air pressure display can be seen almost from the front while standing up. This eliminates the need to interrupt the air injecting operation using the air injecting device for the bicycle and confirm the display, or to perform the injecting operation by multiple workers.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic side view of a fire extinguisher training apparatus according to an embodiment. In the figure, elements similar to the conventional elements shown in FIG. 4 are designated by the same reference numerals.

As shown in the figure, an opening 12a is formed in the side wall of the cylindrical main body 12, and a tube portion 32 protruding outward from the opening 12a is provided. As for the shape of this tube portion, first, a first protruding portion 32a is provided in a direction substantially perpendicular to the vertical axis direction (side wall surface direction) of the cylindrical main body 12, and the upright portion 32b is bent upward at an intermediate position thereof. It is provided. Therefore, the shape as a whole is bent upward by approximately 90 degrees. In the figure, a plug 34 used at the time of injecting air and a cap 36 of the plug thereof are attached to the tip end opening 32c of the pipe portion 32.

The operation of injecting water into the tubular body 12 is performed with the plug 34 removed. FIG. 2 is an explanatory diagram showing the water injection state. As shown in the drawing, the funnel 28 is inserted into the tip end opening 32c of the pipe portion 32 which is opened upward, and water is injected. In this case, the cylindrical main body 12 is in an upright state, and the water surface position can be visually confirmed from the tip opening 32c when the water amount reaches an appropriate position during water injection. This operation can, of course, be performed by removing the funnel 28, but it is also possible to confirm the operation through the gap while the funnel 28 is in use. Since the position of the broken line X is the most suitable for the amount of water as described in the conventional example, after confirming the water surface, an appropriate amount of water can be discarded from the tip opening 32c to set an appropriate water level if necessary. As described above, in the present embodiment, the water injection work can be performed while the cylindrical main body 12 is kept upright, and a substantially appropriate amount of water can be set by one operation.

Next, FIG. 3 is a schematic front view of the fire extinguisher training apparatus according to the embodiment. An air pressure display meter 22 is provided at the upper position of the fire extinguisher training device 10 as in the conventional case, but the characteristic feature of the present invention is that the display surface 22a is inclined. is there. In this embodiment, the inclination angle α is set to 62 ° with respect to the vertical direction.

As a result, after the injection of the appropriate amount of water is completed by the above operation, the air injection plug 34 is attached to the tip opening 32c of the pipe portion 32 to perform the air injection operation. At that time, the worker usually uses a bicycle air injection device or the like to perform the work in a standing state. Therefore, the display surface 22a of the air pressure display meter 22 faces in a direction substantially facing the line of sight of the operator who is performing the air injection operation. Therefore, the worker can easily perform the air injection work while checking the display surface 22a without changing the viewpoint while standing.

After the injection of appropriate water and the injection of appropriate air are completed in this way, the plug 36 is covered with the cap 36, and the preparation work of the fire extinguisher training apparatus is completed. According to the above-described embodiment, the work at the preparatory stage of the fire extinguisher training apparatus 10 becomes extremely smooth, and it becomes possible to more appropriately set the water injection amount and the air pressure.

It should be noted that the present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope of the gist of the invention. For example, the length and diameter of the pipe portion 32 can be variously set according to the size of the fire extinguisher. Further, the inclination angle of the display surface 22a of the air pressure display meter 22 can be variously set according to the height of the fire extinguisher training device 10, and the angle can be arbitrarily adjusted within a predetermined inclination angle range. It is also possible to adopt a configuration that allows it.

 As described above, according to the fire extinguisher training apparatus according to the present invention, the apparatus preparation process can be performed extremely smoothly and appropriately. That is, according to the fire extinguisher training device according to claim 1, it is possible to easily and appropriately inject an appropriate amount of water into the main body, and according to the fire extinguisher training device according to claim 2, It becomes possible to carry out the injection operation of the smoother. This will improve the usability of the fire extinguisher training device and contribute to its spread.
