FIG. 1 is a side view of the portable drug release device 1 according to the embodiment of the present invention when it is erected. In FIGS. 1 to 3, some configurations are omitted in order to make the main part easier to see. A drug flow path 3 for delivering the drug is connected to the tank 2 in which the drug for preventing the spread of fire is sealed. The chemical may be used for fire, for example, a chemical for preventing the spread of fire or a chemical for extinguishing a fire. The drug flow path 3 through which the drug passes at the time of release has a drug delivery pipe 31, a hose 32, and a nozzle 33. In FIGS. 1 to 3, a part of the hose 32 and the nozzle 33 and the like are omitted. The delivery insertion tube 311 at the lower part of the drug delivery tube 31 is inserted into the inside from the upper part of the tank 2. A rotary joint 312 is provided on the upper part of the drug delivery pipe 31. The rotating joint 312 has a rotating mechanism 313 that rotates 360 °, for example, composed of a swivel joint or the like. A bent portion 314 is provided on the bent portion 314, and a hose 32 is connected to an outflow connecting portion 315 which is an end portion of the drug delivery pipe 31. A nozzle 33 is attached to the tip of the hose 32. The hose 32 is a shape-retaining hose whose internal insertion hole is not crushed even when an external force is applied. The length of the hose 32 can be set as appropriate, but for example, a hose of about 4 m to 20 m can be used. Long hoses are used in areas where the road width is narrow and it is difficult to transport or move the equipment. In FIG. 1, the configuration of the hose 32 after the middle of the hose 32 and the like is omitted. Further, in the rotation mechanism 313, the inflow connection portion 321 in which the upper and lower pipes can rotate 360 ° and the rotation mechanism 313 have the same axial direction as the drug delivery pipe 31, but the bending portion 314 has an axial direction. It is bent 45 °. Therefore, the outflow connection portion 315 connected to the bending portion 314 is displaced by 45 ° in the axial direction from the drug delivery pipe 31. A hose 32 is connected to the outflow connection portion 315. When the portable drug discharge device 1 is erected, the hose 32 is rotated 45 ° upward by the rotation mechanism 313 in any direction of 360 ° around the axis of the delivery insertion tube 311. It is possible.

A handle 4 is attached to the tank 2 so as to extend diagonally upward. The handle 4 is an upright body, and the arm (lower) 43 and the arm (upper) 42 extend upward at an angle of 45 ° from both sides of the upper part of the tank 2 and are connected to the grip 41. .. The grip portion 41 is provided at a position diagonally upward from the upper end of the drug delivery pipe 31, and connects the arm portion (upper portion) 42 in the lateral direction. A plate 5 is attached to the lower side of the arm (upper part) 42. Further, a wheel 6 is attached to the lower part of the tank via a metal fitting. In FIG. 1, the description of the spokes inside the wheel 6 is omitted. Further, at the lower part of the tank 2, for example, three legs 7 which are erection mechanisms for maintaining the tank 2 in an upright state are provided at equal intervals. When the portable drug release device 1 is in an upright state, the legs 7 are in contact with the ground to support the portable drug release device 1, and at this time, the wheels 6 are not in contact with the ground. When moving, the handle 4 is pulled to the right in FIG. 1, the portable drug discharging device 1 is tilted to bring the wheel 6 into contact with the ground, and the leg 7 is lifted. A pressurized gas container 81 of the pressurized gas supply mechanism 8 is attached to the side portion of the tank 2, and the pressurized gas is supplied from the pressure supply cap 85 to the inside of the tank 2.

FIG. 2 is a front view of the portable drug release device 1 according to the embodiment of the present invention when it is erected. Further, FIG. 3 is a top view of the portable drug release device 1 according to the embodiment of the present invention when it is erected. The handle 4 has a grip portion 41 provided horizontally on the upper portion, and two arms portions that are close to the tank 2 and are attached to both sides of the upper portion of the tank 2 and expand laterally and diagonally upward from the portions attached to both sides. It has (bottom) 43. Then, it has two parallel arm portions (upper parts) 42 provided on the grip portion 41 and connected to both ends of the grip portion 41. The grip portion 41 is formed wider than both sides of the tank 2 by extending the two arm portions (lower portion) 43 and connecting them to the two arm portions (upper portion) 42. The height of the position where the arm portion (upper part) 42 and the arm portion (lower part) 43 are connected is slightly lower than the height position where the bent portion 314 is provided. Further, the length of the grip portion 41 is about twice the outer diameter of the tank 2, and is formed to be slightly wider than the width of the two wheels 6. The length of the arm portion (upper part) 42 and the arm portion (lower part) 43 is determined so that the depth of the grip portion 41 is located inside (tank 2 side) from the end portion of the wheel 6 (see FIG. 3). ). Since the length (width) of the grip portion 41 is formed to be wide in this way, it is possible for a plurality of people to hold the grip portion 41 and push or pull the portable drug release device 1 during transportation. Since the length in the depth direction is located inside the wheel 6, the size of the drug release device 1 itself can be made compact. Further, since the two arms (lower) 43 are widened, the installation width of the two arms (upper) 42 is widened, and the radius when the hose 32 is wound around both arms (upper) 42 is increased. Can be made larger. Further, a plate 5 made of a metal plate or the like is installed between the two arms (upper part) 42. On the plate 5, the operational precautions "Please completely release the gas in the container before (re) filling" are displayed so that it can be seen from above, but the two arms (lower part) 43 are widened. Therefore, the width of the plate 5 can be increased. Further, as shown in FIG. 2, the portable drug release device 1 is vertically erected by three legs 7 which are erection mechanisms.

The portable drug release device 1 further includes a pressurized gas supply mechanism 8. By sending the pressurized gas into the tank 2 by the pressurized gas supply mechanism 8, the chemicals filled in the tank 2 are pushed out into the drug flow path 3. The pressurized gas supply mechanism 8 includes a pressurized gas container 81, a pressure regulator 82, a pressure meter 83, a pressure hose 84, and a pressure supply cap 85. The pressurized gas container 81 is filled with pressurized nitrogen gas. The pressurized gas container 81 is attached to the tank 2 via a metal fitting such as a buckle that can be easily attached and detached. The tank 2 of the pressurized gas container 81 is attached to the side where the grip portion 41 of the handle 4 is located, and is provided between the arm portions (upper portion) 42 provided above when viewed in the horizontal direction (FIG. 3). reference). The lower end of the pressurized gas container 81 is provided above the axle of the wheel 6. In FIG. 3, a pressure regulator 82 is connected to the pressurized gas container 81. Two pressure meters 83 are provided next to the pressure regulator 82. The pressure regulator 82 is connected to the pressure supply cap 85 via the pressure hose 84. The nitrogen gas filled in the pressurized gas container 81 is supplied to the inside of the tank 2 from the pressure supply cap 85 via the pressure regulator 82 and the pressure hose 84. The drug in the tank 2 is pushed by the nitrogen gas and is delivered from the drug delivery pipe 31 to the drug flow path 3. For instruments such as the pressure regulator 82 and the pressure meter 83, a mounting base 86 is provided in a space formed by one arm (lower part) 43, a tank 2, and a pressurized gas container 81, and the mounting base 86 is provided. It may be provided on the top. The mounting height of the pressure regulator 82 is determined by the mounting base 86, and the pressure regulator 82 is provided at a position above the tank 2 and slightly below the opening / closing handle 811 of the pressurized gas container 81 ( (See FIG. 5). At this position, the pressure meter 83 and the like can be easily checked even when the hose 32 is wound around the handle 4.

In the portable drug discharge device 1 of the present embodiment, a rotary joint 312 having a rotary mechanism 313 is provided above the drug delivery pipe 31. Therefore, when the hose 32 is routed at a fire site, the hose 32 can be directed in either direction from the upper part of the tank 2 to prevent the hose 32 from twisting. Further, by providing the bent portion 314, it is easy for the rotation mechanism 313 to rotate when the direction of the hose 32 is changed. The hose 32 shown in FIG. 3 can be easily extended in any direction of 360 ° as viewed from the drug delivery pipe 31. Further, since the bent portion 314 faces diagonally upward, the hose 32 faces diagonally upward as shown in FIG. Therefore, when the hose 32 rotates in the direction of the grip portion 41, the hose 32 easily passes over the grip portion 41. In the present embodiment, since the hose 32 is a shape-retaining hose, it has a certain degree of hardness, and the hose 32 is obliquely upward and retains its shape to some extent. Therefore, it is easier to pass over the grip portion 41 of the handle 4. Further, in the present embodiment, the upper end of the outflow connection portion 315 in which the drug delivery pipe 31 is connected to the hose 32 is a position 10 cm below the position of the upper end of the grip portion 41 on the handle 4. Even with such a positional relationship, the hose 32 easily passes over the grip portion 41 during rotation.

4 to 6 are photographs of the stored state in which the hose 32 is supported in FIGS. 1 to 3. The portable drug release device 1 of the present embodiment can support the hose 32 by winding the hose 32 around the handle 4 at the time of storage. In FIGS. 4 to 6, the hose 32 is wound around and supported by the two arms (upper part) 42. Since the distance from the tank 2 is widened by the two arms (lower part) 43, the space between the two arms (upper part) 42 is wide. Therefore, a sufficient radius can be obtained for winding the hose 32. Further, a plate 5 for fixing the nozzle 33 is attached between the two arm portions (upper portion) 42 so as to be separated from the grip portion 41. Then, as shown in FIGS. 2 and 3, precautions for using the portable drug release device 1 are described on the upper surface of the plate 5. Further, the nozzle 33 can be locked to the plate 5, and the nozzle 33 is locked to the plate 5 as shown in FIG. 5 during storage and transportation of supporting the hose 32. Since the plate 5 has two arms (lower part) 43 and the width of the two arms (upper part) 42 is widened, there is a wide place to describe the precautions, and there is a place to lock the nozzle lever 331. Wide and easy to lock.

Here, the handle 4 will be further described. The handle 4 is connected to the grip portion 41 and becomes an arm portion (upper portion) 42 which becomes a wide widening portion 42A as shown in FIG. 2, and an arm which is connected to the tank 2 side and becomes a narrow narrow portion 43A. It is provided with a portion (lower part) 43. The widening portion 42A mainly functions as a hose support portion for supporting the hose 32, and can be wound three times or more depending on the length of the hose. Even when the hose 32 is wound, the two arms (upper part) 42 are in a parallel positional relationship, so that when it is necessary to release the drug, the hose 32 can be pulled out from the widening portion 42A and removed. It is easy and the removed hose 32 can be placed on the ground in place. Since the handle 4 is inclined, it is difficult to remove all of the hose 32 from the handle 4 if the hose length is long due to the weight of the hose 32 when the portable drug discharge device 1 is erected. However, if the handle 4 is pulled downward so that the handle 4 is tilted in the horizontal direction, the hose 32 can be easily removed from the arm (upper part) 42 of the handle 4, which is a hose support portion. is there. At this time, since the hose 32 is also heavy, it is easy to tilt the handle 4 (tank 2). When transporting the portable drug discharging device 1, the handle 4 is tilted, but the hose 32 does not fall from the handle 4 unless it is tilted below the horizontal direction. Even when the tank 2 is erected, the hose 32 wound around the arm (upper part) 42 of the handle 4 does not slide down toward the arm (lower part) 43 in the downward direction. This is because the base end of the hose 32 is connected to the outflow connection portion 315 in addition to the frictional force between the arm portion (upper portion) 42 and the hose 32. The upper end of the outflow connection portion 315 to which the hose 32 and the drug delivery pipe 31 are connected is 10 cm below the position of the upper end of the grip portion 41 on the handle 4, and the difference from the height of the grip portion 41 is too large. The absence acts to prevent the hose 32 from slipping off.

Further, by providing the drug delivery pipe 31 upright in the tank 2 and using the rotation mechanism 313 and the bending portion 314, the outflow connection portion 315 can be directed toward the grip portion 41, and thus the base of the hose 32. It becomes easy to wind the end side around the widening portion 42A. The hose 32 is basically wound and supported by using the widening portion 42A. This is because when the hose 32 is wound only around the widening portion 42A, the hose 32 does not hang on the narrowing portion 43A, so that instruments such as a pressure meter 83 provided between the arms (lower part) 43 which is the narrowing portion are used. This is because it is easy to check and the inspection work of the tank 2 can be performed with the hose 32 hung without removing the hose 32 from the handle 4.

FIG. 7 shows the nozzle 33 of the portable drug discharging device 1 according to the embodiment of the present invention. The tip end side of the nozzle 33 is a discharge port 333, and the hose connection portion 334 at the base is connected to the hose 32. The nozzle 33 has a nozzle lever 331, and the nozzle valve 332 provided in the nozzle 33 can be opened and closed by rotating the nozzle lever 331. The position of the nozzle lever 331 in FIG. 7 is a state in which the nozzle valve 332 is closed. Then, by turning the nozzle lever 331 toward the hose connecting portion 334 in the direction of the arrow in FIG. 7, the nozzle valve 332 can be gradually opened. The opening of the nozzle valve 332 is maximized when the nozzle lever 331 faces the direction of the hose connection portion 334 and coincides with the axial direction of the nozzle 33. In the closed state of FIG. 7, the nozzle lever 331 does not rotate in the opposite direction of the arrow due to the stopper (not shown). The plate 5 is described with precautions, and the nozzle 33 can be locked by the nozzle lever 331. In FIG. 5, the nozzle 33 is locked by hanging the nozzle lever 331 on the plate 5 with the nozzle valve 332 open. The nozzle lever 331 is engaged with the plate 5 regardless of whether the nozzle valve 332 is open as shown in FIG. 5 or closed as shown in FIG. 7 during storage for supporting the hose 32 and during transportation of the portable drug discharge device 1. Can be stopped. Further, the arm portion (upper part) 42 and the arm portion (lower part) 43 of the handle 4 extend obliquely upward from the tank 2. Therefore, even if the hose 32 slides down in the direction of the tank 2, it does not hang on the drug delivery pipe 31 protruding above the tank 2 and slide forward beyond the tank 2.

Although not shown, the nozzle 33 may be provided with a rotary joint. By providing the rotary joint on the nozzle 33 side, it is possible to rotate the direction of the nozzle 33 in an easy-to-use state without twisting the hose 32. The nozzle lever 331 of FIG. 7 is provided with a semicircular plate-shaped indicator 335. The indicator 335 is illustrated with an arrow indicating the direction in which the nozzle lever 331 is rotated, and is rotated together with the nozzle lever 331 to indicate the degree of opening of the nozzle valve 332. The indicator 335 is illustrated with an arrow indicating a state in which the drug flows when the axial directions of the nozzle lever 331 and the nozzle 33 coincide with each other. The semi-circular indicator 335 has protrusions formed at the tip of the indicator 335 at the three corresponding positions of drug release (strong), drug release (weak), and drug stop, making it easy to understand the turning condition at a glance. There is.

When using the portable drug release device 1, normally, the portable drug release device 1 can be erected and stored by supporting the hose 32 in the state shown in FIGS. 4 to 6. At this time, since the nozzle lever 331 protrudes from the main body of the nozzle 33 regardless of whether the nozzle valve 332 is in the open position as shown in FIG. 5 or in the closed position as shown in FIG. 7, it can be locked to the plate 5. it can. Then, in the event of a fire, pull the handle 4 while supporting the hose 32 in the state shown in FIGS. 4 to 6 to tilt the portable chemical release device 1, and use the wheels 6 to move to the fire site or the site where the chemical should be released. Can be done. The nozzle lever 331 is hung on the plate 5 even during movement, and the hose 32 does not come loose due to vibration or the like.

<Modification example>
In the above embodiment, the bent portions 314 intersect at 45 ° in the axial direction, but if the bent portions 314 are bent diagonally upward at the intersection of 20 to 70 °, the hose 32 has an effect of avoiding the grip portion 41 during handling. .. Even if the hose 32 is attached coaxially with the drug delivery pipe 31 without providing the bent portion 314, the twist of the hose 32 is eliminated by the rotating mechanism 313. Further, the bent portion 314 has an effect that the hose 32 can be easily handled even if the hose 32 is bent sideways at an intersection of 70 ° or more such as 90 °.

In the present embodiment, the upper end of the outflow connection portion 315 is a position 10 cm below the position of the upper end of the handle 4. However, not limited to this, if the upper end of the outflow connection portion 315 has a height within 15 cm above and below the position of the upper end of the handle 4, the hose 32 is unlikely to interfere with the handle 4 during rotation. Further, in the present embodiment, the handle 4 is attached so as to extend diagonally upward from the tank 2, but it may be attached in the lateral direction or the upward direction.

Further, although the two arm portions (upper part) 42 of the present embodiment are parallel to each other, even if the two arm portions (lower part) 43 closer to the portion attached to the tank 2 are spread upward at a looser angle. Often, the space between the arm (upper part) 42 and the arm (lower part) 43 may be straight without bending. Further, a protruding portion from upward to outward may be provided in the vicinity of the connecting portion between the arm portion (upper portion) 42 and the arm portion (lower portion) 43 to serve as a stopper for the hose 32. By providing the protruding portion, it is possible to prevent the hose 32 wound around the arm portion (upper portion) 42 from slipping down in the direction of the tank 2. Further, since the protruding portion serves as a stopper even when the hose 32 is stored, it is easy to wind the hose 32 around the arm portion (upper portion) 42.

Although precautions are described on the plate 5 of the present embodiment, other items may or may not be described. Further, in the present embodiment, the plate 5 is used as a means for fixing the nozzle 33 by hanging the nozzle 33, but the shape and position of the means for fixing the nozzle are not limited. For example, a tubular holder for accommodating the nozzle may be provided in the tank or the gas pressure vessel, or a holder having a mechanism capable of holding the nozzle may be provided in the handle or the arm.
