Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-extinguishing device. Background Art

[0002] At present, with the popularization of new energy vehicles, more and more electric vehicles are running on the road. Because the batteries of electric vehicles are arranged in a centralized manner and the battery compartment has high energy, once a fire occurs in an electric vehicle, the entire vehicle can be scrapped in a short time. Moreover, the batteries of most electric vehicles are installed at the bottom of the vehicle body.

[0003] Existing firefighting equipment can extend under an electric vehicle to spray water, but due to its fixed length, it cannot be applied to electric vehicles with varying underbody areas. The water spray range cannot fully cover the underbody of some large electric vehicles, making firefighting ineffective, and some flames remain unextinguished. Furthermore, excessive length of firefighting equipment is inconvenient to transport, so it cannot be increased based on the vehicle's underbody area. Utility Model Content

[0004] The purpose of the utility model is to provide a fire extinguishing device which can solve the problems that the existing fire fighting equipment has a small application range and is inconvenient to transport.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A fire extinguishing device includes a first delivery pipe, a second delivery pipe, and multiple nozzles arranged on the first delivery pipe and the second delivery pipe. The first delivery pipe and the second delivery pipe are both U-shaped pipes. A caster and a fire joint are provided in the middle of the first delivery pipe. The middle and both sides of the second delivery pipe are also provided with at least one caster. The two ends of the first delivery pipe are connected to the two ends of the second delivery pipe by a flexible joint. The first delivery pipe and the second delivery pipe can be folded and unfolded by rotating the first delivery pipe.

[0007] Preferably, a branch pipe is provided in the middle of the second delivery pipe, and a plurality of nozzles are also provided on the branch pipe.

[0008] Preferably, a mounting seat is fixedly provided in the middle of the first conveying tube, and a handrail is rotatably connected to the mounting seat, and the handrail is rotated to achieve folding and unfolding of the handrail and the first conveying tube.

[0009] Preferably, the acute angle between the nozzle and the horizontal plane is 30°-75°.

[0010] The utility model solves the problem of insufficient length of existing fire extinguishing equipment by providing a first delivery pipe and a second delivery pipe. At the same time, by providing a flexible joint, the first delivery pipe and the second delivery pipe can be folded, so that the length of the fire extinguishing device can be adjusted and the folding structure is convenient for transportation.

[0015] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0016] The following describes the embodiments of the present disclosure through specific concrete examples, and those skilled in the art can easily understand the advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0017] Example 1

[0018] The present invention solves the problem of insufficient length of existing fire-fighting equipment by providing a first delivery pipe 1 and a second delivery pipe 2. Furthermore, by providing a flexible joint 3, the first delivery pipe 1 and the second delivery pipe 2 can be folded, so that the length of the fire-fighting device can be adjusted and the folding structure is convenient for transportation.

[0019] like Figure 1As shown, a fire extinguishing device includes a first delivery pipe 1, a second delivery pipe 2, and a plurality of nozzles 6 arranged on the first delivery pipe 1 and the second delivery pipe 2. The first delivery pipe 1 and the second delivery pipe 2 are both U-shaped pipes; a caster 4 and a fire connector 5 are provided in the middle of the first delivery pipe 1; at least one caster 4 is also provided in the middle and on both sides of the second delivery pipe 2; the two ends of the first delivery pipe 1 are connected to the two ends of the second delivery pipe 2 by a flexible joint 3, and the first delivery pipe 1 and the second delivery pipe 2 can be folded and unfolded by rotating the first delivery pipe 1.

[0020] Furthermore, a branch pipe 201 is provided in the middle of the second delivery pipe 2 , and a plurality of nozzles 6 are also provided on the branch pipe 201 .

[0021] Furthermore, a mounting seat 8 is fixedly provided in the middle of the first conveying pipe 1 , and an armrest 7 is rotatably connected to the mounting seat 8 . The armrest 7 is rotated to achieve folding and unfolding of the armrest 7 and the first conveying pipe 1 .

[0022] Furthermore, the acute angle between the nozzle 6 and the horizontal plane is 30°-75°. According to the optimal angle range obtained according to the height of the vehicle chassis, the spray angle and range of the nozzle 6 are limited, thereby effectively extinguishing the fire on the bottom of the burning vehicle.

[0023] Working principle:

[0024] During transportation, the fire extinguishing device is in a folded state. Figure 2 After being transported to the accident site, the first delivery tube 1 and the handrail 7 are rotated to release the folded state of the first delivery tube 1, the second delivery tube 2 and the handrail 7. Figure 1 As shown, the firefighter connects the water pipe on the fire truck to the fire connector 5 of the fire extinguishing device, then holds the handrail 7 and pushes the fire extinguishing device quickly toward the bottom of the burning vehicle, and then quickly evacuates the scene. The high-pressure water flow ejected by the nozzle 6 extinguishes the fire at the bottom of the burning vehicle.
