Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1a to 2d, the present application discloses a linked opening vehicle-mounted fire extinguishing apparatus, which includes a housing 30, a storage tank 31 for storing fire extinguishing medium, a spray gun 32 for spraying fire extinguishing medium, and a delivery assembly 33 connecting the storage tank 31 and the spray gun 32 are disposed on the housing 30;

the conveying assembly 33 comprises a connecting hose 331 for connecting the storage tank 31 and the spray gun 32 and a rotary table 332 for accommodating the connecting hose 331, wherein the rotary table 332 comprises a bracket 333 for fixing, an accommodating disc 334 rotatably mounted on the bracket 333 and a first locking mechanism 335 arranged on the bracket 333 for limiting the accommodating disc 334 to rotate relative to the bracket 333; a second locking mechanism 336 for controlling the opening or closing of the storage tank 31 is arranged between the storage tank 31 and the connecting hose 331;

the vehicle-mounted fire extinguishing apparatus further comprises a trigger assembly 34 linked with the first locking mechanism 335 and/or the second locking mechanism 336, the trigger assembly 34 is arranged as follows:

the spray gun 32 is detachably accommodated on a gun holder (not shown), and the trigger assembly 34 is arranged on the spray gun 32 and triggers when the spray gun 32 is far away from the gun holder; and/or

The in-vehicle fire extinguishing apparatus further includes a shield cover 301 for closing the housing 30, and the trigger assembly 34 is provided on the shield cover 301 and is triggered when the shield cover 301 is away from the housing 30.

The case 30 in the present embodiment has various forms, such as a closed box structure, for protecting various parts; for example, a semi-open type frame structure is favorable for taking and placing each part and connecting and arranging pipelines; such as a fully open support platform structure, etc. Thus, the term "disposed on the housing" as used herein is to be understood to refer to a broad relationship of connection, not a specific spatial relationship. For example, in some embodiments, the storage tank 31 includes a reservoir 311 and a gas bottle 312, and may be disposed outside the housing 30 when the reservoir 311 is bulky. The specific spatial relationship can be adjusted as required according to actual conditions.

The first locking mechanism 335 locks the rotating disc 332, and when the first locking mechanism 335 is locked, the rotating accommodating disc 334 cannot rotate relative to the bracket 333, so that the connecting hose 331 cannot be released, and the stability of accommodating the connecting hose 331 in a vehicle-mounted bumping environment is ensured. Accordingly, the second locking mechanism 336 provides for closure of the storage tank 31 without loss of the fire extinguishing medium in a vehicle-mounted bumpy environment. When the spray gun 32 is moved away from the gun holder and/or the shielding cover 301 is opened relative to the housing 30 by the trigger assembly 34, the first locking mechanism 335 and the second locking mechanism 336 are unlocked accordingly, so that the fire extinguishing apparatus mounted on the vehicle in the present application is enabled. The gun clip can be designed into a U-shaped clip holder fixed on the shell 30 and used for clamping the tubular part of the spray gun, and the design can give consideration to the stable effect during fixation and the convenient effect during separation.

The technical scheme who discloses this application is seen in the synthesis through the setting and the linkage of trigger component 34, first locking mechanical system 335 and second locking mechanical system 336, has solved the loaded down with trivial details problem of extinguishing device operating procedure among the prior art, has improved the work efficiency of putting out a fire when guaranteeing the stability of on-vehicle abominable operating mode down each part, and quick response has positive meaning in the operation of putting out a fire.

In the arrangement of the first locking mechanism 335, referring to an embodiment, the first locking mechanism 335 includes:

a lock hole 3351 provided in the accommodating tray 334 and opened toward the holder 333;

the lock pin 3352 is movably arranged on the bracket 333 in a penetrating way, and the lock pin 3352 has a locking state of being clamped with the lock hole 3351 and a releasing state of being separated from the lock hole 3351;

trigger assembly 34 is used to hold lock pin 3352 in the unlocked state.

The different positions of the locking pin 3352 enable locking and unlocking of the receiving tray 334 relative to the bracket 333. In one embodiment, lock pin 3352 is provided with a resilient member (not shown) that maintains itself in a locked position, which maintains the stability of first locking mechanism 335 in an on-board environment. The action of trigger assembly 34 drives locking pin 3352 against the force of the resilient member to effect release. In the illustrated details, the direction of movement of lock pin 3352 is maintained perpendicular to the direction of rotation of housing tray 334 to achieve maximum locking torque of lock pin 3352 to avoid accidental unlocking.

In the arrangement of the second locking mechanism 336, referring to an embodiment, the second locking mechanism 336 is a valve disposed between the storage tank 31 and the connection hose 331.

The valve has good sealing performance. For better linkage with the trigger assembly 34, reference may be made to a rocker arm 3361 in the manner shown in the drawings. In the details of the arrangement of the storage tank 31, referring to an embodiment, the storage tank 31 includes:

a liquid storage container 311 for storing a liquid fire extinguishing medium;

a gas cylinder 312 for storing gaseous extinguishing medium;

the second locking mechanism 336 is provided at least between the gas cylinder 312 and the connection hose 331.

In use of the fire suppression apparatus, the gas cylinder 312 is typically the source of pressure and therefore has a high sealing requirement. In some embodiments, the reservoir 311 and the gas cylinder 312 are each provided with a valve. Further, in the case of a fire caused by combustible materials such as gasoline, a foaming agent is required to perform a fire extinguishing operation. Therefore, in one embodiment, the storage tank 31 further comprises a foam tank 313, and a controllable valve is arranged between the foam tank 313 and the connection hose 331. The controllable valve may be the second locking mechanism 336 described above, or may be a separate valve.

The first and

second locking mechanisms

335 and 336 require unlocking by the trigger assembly 34. Referring to one embodiment, the trigger assembly 34 includes

An active end 341 fixed to the spray gun 32 and/or the shield cover 301;

a passive end 342 secured to the first locking mechanism 335 and/or the second locking mechanism 336;

and a flexible connecting member 343 forcedly connected between the active end 341 and the passive end 342.

The flexible connecting member 343 is used for transmitting the torque received by the active end 341 to the passive end 342, thereby achieving the unlocking action of the first locking mechanism 335 and/or the second locking mechanism 336. The provision of the flexible connector 343 has the advantage of ease of deployment, but is prone to jamming. Thus, referring to one embodiment, the trigger assembly 34 further includes a plurality of guides 344, the guides 344 being used to guide the force path of the flexible linkage 343.

The guide 344 is in principle required to enable the reversal of the flexible connection 343, which can be achieved by means of rollers provided on the housing 30 or on the screening cover 301. The flexible connecting member 343 may be a flexible metal or fiber rope.

When the active end 341 is disposed on the shielding cover 301, the opening range of the shielding cover 301 is small, and the opening range can be overcome by the elasticity of the flexible member or the limiting mechanism. When the active end 341 is disposed on the lance 32, the flexible linkage 343 may affect the movement of the lance 32. Referring to an embodiment, the trigger assembly 34 further includes a disconnecting assembly 345 disposed on the flexible link, the disconnecting assembly 345 for disconnecting the flexible link 343 in a predetermined case.

The release assembly 345 overcomes the above-described problems to ensure that the spray gun 32 can be used to unlock the first locking mechanism 335 and/or the second locking mechanism 336, but does not interfere with the free movement of the spray gun 32 after the unlocking action is completed.

The predetermined condition for the detachment of the detachment assembly 345 may be that the flexible connector 343 is disconnected when the detachment assembly 345 is subjected to a pulling or pushing force greater than a predetermined value. For example, the decoupling assembly 345 may be implemented by providing a stress-weakening of the flexible connector 343, such as a location on the flexible connector that is susceptible to breakage, but this design may increase the maintenance cost of the fire suppression apparatus. Also referring to an embodiment, the separating assembly 345 includes:

a first separation joint 3451 integrally formed in a cylindrical shape with one end open and the other end closed, the closed end of the first separation joint 3451 being used for connecting the flexible connecting member 343, and the inside of the first separation joint 3451 being a fitting area 3452;

the second separation joint 3453 has one end for connecting the flexible connecting member 343 and the other end detachably connected to the first separation joint 3451 through the fitting area 3452.

When the first and

second separation joints

3451 and 3453 are connected, they are substantially of a unitary structure and function as the flexible connection member 343. The flexible connecting piece 343 is used for transmitting torque, when the two are separated through the matching area 3452, disconnection of the flexible connecting piece 343 is realized, reconnection of the flexible connecting piece 343 can be conveniently realized after use is finished, and maintenance cost is reduced.

In terms of controlling the separating moment, in an embodiment, the second separating joint 3453 is provided with a matching ring groove 3454, the inner sidewall of the matching region 3452 is provided with a radially protruding matching ring rib 3456, the sidewall of the matching ring groove 3454 is provided with a guiding inclined plane 3455, and the matching ring rib 3456 is a flexible member.

The slope of the guiding ramp 3455 controls the separation moment between the two components, and the height of the ring rib 3456 also controls the above function. As mentioned above, the flexible part of the engaging rib 3456 can be understood as the engaging rib 3456 made of rubber, plastic or other easily deformable materials, and can also be understood as the engaging rib 3456 made of metal material with low height.

The preset condition for the separation of the separation assembly 345 may also be that the flexible connector 343 is disconnected when the separation assembly 345 interacts with a component. Referring to the embodiment shown in fig. 2c, the first separation joint 3451 is actually composed of a first part and a second part, wherein the main mating area 3452 is provided by the first part and the second part is arranged over the first part. In this embodiment, the mating ring rib 3456 releases the second separation joint 3453 by deforming or moving itself, and the deformation or movement of the mating ring rib 3456 is restricted by the second member, and only when the second member is close to the first member, the groove inside the second member is aligned with the mating ring rib 3456, thereby releasing the deformation or movement stroke of the mating ring rib 3456. The advantage of this embodiment is that the first and

second disconnect joints

3451 and 3453 can be better connected to ensure that the disconnect assembly 345 does not separate before the release action is completed during use.

At the same time, the second component can also provide a trigger condition for the release action of the release assembly 345. This trigger condition enables better control of the state of the flexible linkage 343. Referring to an embodiment, the separating assembly 345 further includes a separating baffle 3457, a separating hole (not shown) is formed inside the separating baffle 3457, the flexible connecting member 343 is inserted into the separating hole, and the diameter of the separating hole is larger than the outer diameter of the second separating joint 3453 and smaller than the outer diameter of the first separating joint 3451.

The separation damper 3457 acts on the second member through the outer edge of the separation hole, thereby satisfying the trigger condition of the unlocking action of the separation assembly 345, and achieving the separation of the first separation joint 3451 and the second separation joint 3453. By precise force application with a matched size, the separation operation of the separation assembly 345 can be realized better, more accurately and more quickly. Meanwhile, when the separating assembly 345 separates, the flexible connecting member 343 may be subjected to a large stress, and the arrangement of the embodiment can release the stress concentration on the separating assembly 345, but not on other parts, thereby improving the stability of the separating action.

The effects of the fire extinguishing apparatus of the present application will be exemplarily shown below. For example, a fire extinguishing apparatus equipped with the gas cylinder 312 and the liquid storage container 311 becomes a gas-liquid two-phase fire extinguishing apparatus. The preset liquid storage container 311 is stored with 50 liters of water agent, wherein the water agent can be mixed with foaming agent, the air cylinder 312 is stored with compressed air with pressure of more than 25MPa, the operation can be carried out for about 2 minutes, the fire extinguishing effect can be equivalent to that of a 2000 liter common water gun, particularly, the water tank and the like are well cooled, the oil tank is effectively protected from explosion, and the water tank is well extinguished on the leaked gasoline and diesel fire after the foam is added. The passenger car with the fire can win precious escape time for most passengers due to timely fire extinguishing, and the fire can be extinguished in the initial three minutes under the common condition.

More importantly, when the rotary disc 332 is provided with the connecting hose 331 with the length of more than 30 meters, the spray gun 32 can realize the water mist range with the length of more than 10 meters under the pressure driving of the gas cylinder 312, and can meet the fire point of any part of the vehicle and rescue the fire point of other vehicles with the length of 40 meters nearby. On the basis, by improving the assembling quantity of the fire extinguishing devices in the application, the fire fighting truck which flows in a high-speed whole network is basically formed according to the vehicle density of the highway in China at present, and the truck always arrives at the site in a few minutes in case of fire, so that precious time is won for rescue.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features. When technical features in different embodiments are represented in the same drawing, it can be seen that the drawing also discloses a combination of the embodiments concerned.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
