Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, in particular to a fire fighting water gun for extinguishing electric vehicles. Background Art

[0002] At present, there are three main ways to deal with new energy electric vehicle fires: 1. Use water guns to put out the fire directly; 2. Use foam to put out the fire; 3. Break the vehicle chassis to put out the fire. Methods 1 and 2 cannot effectively control the vehicle chassis battery fire. Once the vehicle battery catches fire, the entire vehicle will burn out; Method 3 has safety hazards and is prone to explosion accidents.

[0003] The batteries of new energy electric vehicles are usually installed on the chassis. They react violently in fires and release a lot of smoke and heat. Immediately cooling them with a large amount of water is the key to fighting electric vehicle fires. The water guns of daily firefighters cannot directly cool them down. Even if the water guns are placed under the chassis of the vehicle, only part of the area is cooled down, and the battery pack cannot be fully covered. The effect is not obvious, and a large amount of water is required. When cooling the batteries, firefighters must advance to a very close distance from the accident vehicle and use a prone position to shoot water to hit the batteries, but this puts firefighters in a dangerous situation. Utility Model Content

[0004] In order to solve the technical problems mentioned in the background technology, the utility model provides a fire hose for extinguishing electric vehicles.

[0005] The utility model adopts the following technical solution: a fire water gun for extinguishing electric vehicles, comprising a gun barrel;

[0006] An extension water pipe is disposed at the end of the first end of the gun barrel;

[0007] The liquid outlet of the extended water pipe is vertically upward;

[0008] The extended water pipe is connected to a multifunctional nozzle;

[0009] The multifunctional nozzle is movably connected to the liquid outlet of the extension water pipe through a rotating joint;

[0010] A quick connector is provided at the second end of the gun barrel;

[0011] A ball valve is arranged at one end of the gun barrel close to the quick connector, and the ball valve is in an open and closed state;

[0012] A small movable pulley is provided at one end of the gun barrel close to the extended water pipe;

[0013] The movable small pulleys are symmetrically arranged on both sides of the gun barrel;

[0014] The movable small pulley is connected to the end of the gun barrel through a folding connection piece;

[0015] The folding connecting member comprises a first connecting rod connected to the gun barrel, a second connecting rod hinged to the first connecting rod, and a spiral tube locking cover sleeved on the first connecting rod and the second connecting rod and threadedly connected to the two;

[0016] When the spiral tube locking cover is completely rotated onto the second connecting rod, the second connecting rod can be horizontally rotated 90° toward the side close to the gun barrel with the hinge point as the center of the circle.

[0017] Furthermore, a filter screen is arranged inside the quick connector.

[0018] Furthermore, a sealing ring is provided at the connection between the quick connector and the gun barrel.

[0019] Furthermore, a support frame is arranged at one end of the gun barrel close to the quick connector; the support frame is designed to be narrow at the top and wide at the bottom.

DETAILED DESCRIPTION

[0026] In order to facilitate those skilled in the art to understand the technical solution of the utility model, further description is now made with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model.

[0027] In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, it is apparent that one or more embodiments may be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0028] like Figure 1 As shown, it is a schematic diagram of the overall structure of the fire water gun for electric vehicles of the utility model, including a gun barrel 1, an extension water pipe 2 is arranged at the end of the first end of the gun barrel 1, and the liquid outlet of the extension water pipe 2 is vertically upward, so that the whole is L-shaped. A multifunctional nozzle 3 is connected to the extension water pipe 2, and the multifunctional nozzle 3 is movably connected to the liquid outlet of the extension water pipe 2 through a rotating joint 4. In this embodiment, the multifunctional nozzle 3 is made of alloy aluminum, high temperature resistant, and has functions such as direct current, spray, and self-defense water curtain. It has strong mobility, its working pressure is 0.3 to 0.8 MPa, the direct current range is 36 meters to 42 meters, and the working flow rate is 2 to 8 liters per second. A quick connector 5 is arranged at the end of the second end of the gun barrel 1, and a ball valve 6 is arranged at one end of the gun barrel 1 close to the quick connector 5, and the ball valve 6 is in an open and closed state. A movable small pulley 7 is arranged at one end of the gun barrel 1 close to the extension water pipe 2, and the movable small pulley 7 is symmetrically arranged on both sides of the gun barrel 1, and the movable small pulley 7 is connected to the end of the gun barrel 1 through a folding connector. The movable small pulley 7 facilitates pushing the gun barrel to the bottom of the vehicle chassis, and the movable small pulley 7 is connected to the end of the gun barrel 1 through a folding connector, which is convenient for opening and retracting.

[0029] In this embodiment, the folding connecting member includes a first connecting rod 8 connected to the gun barrel 1, a second connecting rod 9 hinged to the first connecting rod 8, and a coil locking cover 10 sleeved on the first connecting rod 8 and the second connecting rod 9 and threadedly connected to the two. When the coil locking cover 10 is sleeved on the first connecting rod 8 and the second connecting rod 9, the second connecting rod 9 is opened, and the moving small pulley 7 is pushed to run. When the coil locking cover 10 is completely rotated to the second connecting rod 9, the second connecting rod 9 can be horizontally rotated 90° toward the side close to the gun barrel 1 with the hinge point as the center of the circle, and parallel to the gun barrel 1.
