Description

  The present invention relates to a water gun used for water discharge for fire fighting activities, water discharge for threatening or eliminating a mob or a violating ship, and the like.

  In general, as a means for extinguishing fires and intimidating or eliminating a mob or a violent ship, etc., the fire source, the mob or the breached ship are discharged with a water gun. Patent Document 1 proposes a technique for dealing with ship fire extinguishing.

JP 2006-102307 A

  In the technology described above, water discharge is continued until the ship fire is extinguished, and the water discharge is stopped after the fire is extinguished.

  However, if the target of the water discharge is a mob or a suspicious ship, it is effective as an intimidation or exclusion action for the purpose of non-killing. The effect disappears.

  In addition, the above-described threatening effect or exclusion effect is such that the visibility becomes poor due to the discharged water, or discomfort due to getting wet, and the sustainability of the effect after discharging cannot be expected.

  The present invention has been made in view of the above-described conventional technology, and maintains the functions for normal fire extinguishing work, and when used for threats and exclusions, these threats and exclusion effects can be obtained even after water discharge. An object of the present invention is to provide a water cannon that can be maintained as much as possible.

In order to solve the above-described problem, the water spray gun of the present invention is a water spray gun in which pressurized water is injected through a nozzle, and the pressurized water flowing in the pressurized water supply path is supplied to the pressurized water. It is characterized in that it is provided with adjusting agent supply means for supplying a characteristic adjusting agent for changing the characteristics.

  By adopting such a configuration, it is necessary to inject only pressurized water from the water spray gun and perform more effective threats and exclusions during normal fire extinguishing, etc. If there is, the characteristic adjusting agent is supplied to the pressurized water via the characteristic adjusting agent supply means to change the characteristic of the pressurized water and discharge it to the object.

  And by discharging the pressurized water whose characteristics have changed, it is possible to give a sense of incongruity and anxiety that it is not just water to the discharged water side, and it is possible to continue the intimidation and exclusion effect of the water discharge even after the water discharge is stopped it can.

In the present invention, the property adjusting agent is a highly water-absorbing polymer that absorbs the pressurized water to form a water-containing body, so that the pressurized water can reach the target while the pressurized water reaches the object. Since the particulate water-containing body is generated by being absorbed by the water, the generated water-containing body can be dropped onto the object or the vicinity thereof.

Therefore, on the drained side, a tactile or auditory sensation is caused by a visual change due to the presence of solid foreign substances together with water, or a contact pressure with a hydrous material as a solid or a contact sound. A change is felt, and the above-mentioned discomfort and anxiety increase.
This sense of incongruity and anxiety continues until the cause can be understood.

  Here, the above-described contact pressure and contact sound can be adjusted by appropriately setting the physical properties at the time of water absorption of the superabsorbent polymer in consideration of the pressure at the time of water discharge, the injection speed, etc. Can be killed.

Moreover , by using the adhesive agent as the property adjusting agent, tactile discomfort is given to the discharged water side, and the durability of the effect due to adhesion is ensured.

  Here, by mixing the above-mentioned paste and the superabsorbent polymer at the same time, it is possible to give adhesiveness to the produced water-containing body, and therefore, an effect combining both characteristics can be expected.

  For example, when water is discharged to a suspicious ship or the like, it is possible to expect an effect that the visibility can be taken by attaching the hydrated body to the glass surface of the bridge of the suspicious ship.

Furthermore , by using the property modifier as a colorant that colors the pressurized water, clothes and the like can be colored when exposed to water, giving visual and sensory discomfort, and by coloring Discomfort can be continued.

  Further, when threatening or removing a suspicious ship or the like, the bridge glass surface as described above can be colored to be opaque, and the effect of depriving the eye can be obtained.

Furthermore , by making the said characteristic regulator into the fragrance | flavor which gives an odor to the said pressurized water, while being able to give an olfactory discomfort, the odor can be made to adhere with water and the effect can be continued.

On the other hand, the water gun according to the present invention is characterized in that the adjusting agent supply means is detachably provided at the tip of the nozzle.

  By setting it as such a structure, the application to the existing water cannon can be made easy.

Further, the water gun according to the present invention is characterized in that the adjusting agent supply means supplies the characteristic adjusting agent into the pressurized water by utilizing a venturi effect.

  By setting it as such a structure, it can carry out using the negative pressure generate | occur | produced by the pressurized water which discharges | releases the said characteristic regulator, and can simplify the structure of a regulator supply means.

  According to the present invention, there is provided a water gun capable of maintaining these threats and exclusion effects as much as possible even after water discharge when used for threats and exclusion while maintaining functions for normal fire fighting work. Can be provided.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a ship equipped with a water cannon. A water cannon 2 is installed at the tip of the ship indicated by reference numeral 1, and a regulator supply means according to this embodiment to be described later is provided at the tip of the water cannon 2. 3 is mounted.

  As shown in FIG. 2, the adjusting agent supply means 3 is attached to the tip of the barrel 2a of the water discharge gun 2, and uses an annular protrusion 2b provided on the outer periphery of the tip of the barrel 2a. Installed.

  That is, the adjusting agent supply means 3 includes a cylindrical base portion 3a fitted to the tip of the barrel 2a, a cylindrical clamp portion 3b in which the base portion 3a is installed and screwed, and the clamp portion. A cylindrical mixing portion 3c fitted to 3b, a tank 4 storing a property adjusting agent supplied to the mixing portion 3c, a supply pipe 5 communicating the tank 4 and the mixing portion 3c, This is basically constituted by a pressurized pump 6 that supplies compressed air to the tank 4 and sends the characteristic adjusting agent in the tank 4 to the supply pipe 5.

  Describing these details, the base 3a is fitted on the barrel 2a, and is engaged with and disengaged from the annular projection 2b formed on the barrel 2a. 7 is constituted by a fixing screw 8 which is screwed into one end portion of the clamp portion 3b and clamps and fixes the engaging member 7 between the clamp portion 3b.

  The engaging member 7 includes a fixing ring 7a sandwiched between the clamp portion 3b and the fixing screw 8, and an engaging piece 7b protruding from the fixing ring 7a in the axial direction.

  In the present embodiment, the engagement pieces 7b are provided at four positions with an interval of 90 degrees around the axis of the fixing ring 7a (two positions are shown in the figure), and the respective tip portions are provided. Due to its elasticity, the tip part is directed outward with the connection part with the fixing ring 7a as the center.

  When the engagement pieces 7b are positioned outward, an inscribed circle formed by connecting the inner surfaces of the engagement pieces 7b has an outer diameter of the annular protrusion 2b of the barrel 2a. Is also set to be large.

  A positioning groove 7c is formed on the outer peripheral portion of the fixing ring 7a so as to open toward the side opposite to the side on which the fixing screw 8 is brought into contact, corresponding to the engagement pieces 7b.

  The clamp part 3b is provided with a positioning projection 9 to be engaged with the positioning groove 7c of the engagement member 7 fitted inside the clamp part 3b. 3b and the engaging member 7 are positioned in the axial direction and around the axial line.

  And the through-hole 10 is formed in the four places which set the space | interval of 90 degree | times around the axis line in the axial direction approximate middle part of this clamp part 3b.

  Bearings 11 are integrally provided on the outer surface of the clamp part 3b corresponding to the through holes 10, and a support shaft 12 is provided on each bearing 11 along a direction perpendicular to the axis of the clamp part 3b. It is attached.

  A clamp lever 13 that presses the distal end portion of each locking piece 7b of the engagement member 7 inwardly is attached to the support shaft 12 in a rotatable manner.

  The clamp lever 13 is positioned in the through hole 10 and is pressed against the engaging piece 7b from the outside. The operation portion 13b is positioned on the opposite side and protrudes outward from the clamp portion 3b.

  The clamp lever 13 is bent so that the pressing portion 13a and the operating portion 13b are at a predetermined angle, and the operating portion 13b is formed longer than the pressing portion 13a.

  The clamp lever 13 is positioned opposite to the engagement piece 7b of the engagement member 7 by the engagement of the positioning groove 7c of the engagement member 7 and the positioning protrusion 9 of the clamp portion 3b. ing.

  Further, the clamp lever 13 has its pressing portion 13a outwardly disengaging the engaging piece 7b of the engaging member 7 in a state where the operation portion 13b is positioned at a position substantially parallel to the axis of the clamp portion 3b. The tip of the engaging piece 7b is pushed inward.

  Thus, in a state where the tip of the engaging piece 7b is pushed inward, the tip of the engaging piece 7b is engaged with the annular protrusion 2b of the barrel 2a from the barrel 2a side. Thus, the base portion 3a, the clamp portion 3b, and the mixing portion 3c attached to the clamp portion 3b are fixed to the distal end portion of the barrel 2a.

  Further, when the contact position between the distal end portion of the pressing portion 13a and the engagement piece 7b is positioned beyond the support shaft 12 to which the clamp lever 13 is mounted, the pressing portion 13a is The clamp lever 13 is urged to be held at the clamp position by the elastic force of the joining piece 7b, whereby the clamp lever 13 is held at the fixed position.

  The mixing portion 3c is integrated with the clamp portion 3b by means such as press-fitting, and the end portion inserted into the clamp portion 3b is attached to the barrel 2a while being attached to the barrel 2a. A packing 14 is mounted that contacts the tip and seals the contact in a liquid-tight manner.

  Further, the inner surface of the mixing portion 3c is formed such that a substantially intermediate portion in the axial direction has a smaller diameter than the other end portions, thereby forming a diaphragm A.

A through hole 15 for communicating the inside and outside is formed in the minimum diameter portion, and the supply pipe 5 is connected to an outer end portion of the through hole 15.
Accordingly, when pressurized water is flowed from the water discharge gun 2 into the mixing portion 3c, a pressure effect is generated in the portion of the throttle A and in the through hole 15 due to the venturi action, and the supply pipe is caused by the negative pressure at that time. 5, the property adjusting agent in the tank 4 is drawn into the mixing unit 3c, and the property adjusting agent is mixed with the water flowing in the mixing unit 3c.

Mixing of such a property adjusting agent into the water flowing in the mixing unit 3 c is promoted by increasing the internal pressure of the tank 4 by the pressurizing pump 6 connected to the tank 4.
However, the assistance by the pressurizing pump 6 is arbitrary and can be appropriately selected depending on the type of the property adjusting agent to be mixed.

  In the present embodiment configured as described above, the selected property adjusting agent is stored in the tank, and the adjusting agent supply device 3 is attached to the tip of the water discharge gun 2 as necessary to discharge water. By starting the process, the characteristic adjusting agent in the tank 4 can be discharged while being mixed with water in the mixing unit 3c.

  And by making the said characteristic regulator into the super absorbent polymer which absorbs the said pressurized water and forms a hydrated body, a granular hydrated body can be produced | generated and it can drop to the target object or its vicinity.

  As a result, a visual change due to the presence of solid foreign substances together with water on the discharged water side, or a tactile or auditory sound due to the generation of contact pressure or contact sound with the water-containing body as a solid matter. Changes can be made, and a sense of incongruity and anxiety can be increased.

  Further, by using the adhesive as a property adjusting agent, it is possible to give tactile discomfort to the discharged water side and to maintain the discomfort by adhesion.

  For example, at the time of water discharge to a suspicious ship or the like, it is possible to expect an effect that the visibility can be taken by attaching the hydrated body to the glass surface of the bridge of the suspicious ship.

  Furthermore, by using the property modifier as a colorant that colors the pressurized water, clothes and the like can be colored when exposed to water, giving visual and sensory discomfort, and by coloring Discomfort can be continued.

  Further, when threatening or removing a suspicious ship or the like, the bridge glass surface as described above can be colored to be opaque, and the effect of depriving the eye can be obtained.

  Furthermore, by making the said characteristic regulator into the fragrance | flavor which gives an odor to the said pressurized water, while being able to give an olfactory discomfort, the odor can be made to adhere with water and the effect can be continued.

  On the other hand, when it is not necessary to use the above-described property adjusting agent or when the property adjusting agent supplying means 3 needs to be inspected and maintained, as shown in FIG. After turning 13b away from the clamp 3b, these can be removed from the water cannon 2.

That is, by the rotation of the clamp lever 13 described above, the pressing force to the engaging piece 7b by the pressing portion 13a is released, and accordingly, each engaging piece 7b is separated from the distal end portion of the barrel 2a. Thus, the engagement between each engagement piece 7b and the annular projection 2b at the tip of the barrel 2a is released.
In this state, the adjustment agent supply means 3 can be removed from the water gun 2 by pulling out the adjustment agent supply means 3.

On the other hand, the property adjusting agent can be appropriately selected and variously changed, but a plurality of these can be used simultaneously.
For example, by mixing the above-mentioned paste and the superabsorbent polymer at the same time, it is possible to give the produced water-containing body tackiness and produce an effect of combining the characteristics of both.

  As described above, when a plurality of property adjusting agents are used at the same time, as shown in FIG. 5, a plurality of through holes 15 are formed in the mixing portion 3c, and the supply pipe 5 and the respective through holes 15 are formed. Tanks 4 are connected, and different characteristic modifiers are stored in these tanks 4.
