Description

Technical Field

[0001] The utility model belongs to the technical field of fire fighting tools, and in particular relates to a piercing fire extinguishing gun for fire fighting. Background Art

[0002] For fire accidents in confined spaces, conventional water guns cannot inject fire extinguishing agents into the fire point, which makes rescue more difficult, increases time, and affects rescue efficiency. At the same time, there may be dangers such as backdraft and flashover. Once flashover occurs, the fire will enter a stage of rapid development, which will not only seriously damage indoor items, cause damage to buildings or even collapse; it will also pose a serious threat to the officers and soldiers arriving at the fire scene, thereby hindering the firefighting and rescue work. The backdraft phenomenon threatens the safety of personnel, especially the lives of firefighters, due to its suddenness and strong destructiveness. The sudden increase in pressure caused by flashover may cause the collapse of a local enclosed space, and firefighters may also be injured by sudden shock waves, flames and hot smoke.

[0003] In order to reduce the risk of casualties among firefighters, it is necessary to design a piercing fire extinguisher that can make smaller holes in closed doors and walls of burning buildings, use water to cool down and extinguish high-temperature indoor air and objects without destroying ventilation conditions, control the fire outside the enclosed space, avoid backdraft and flashover that may cause harm to rescuers, and reduce the risks to firefighters.

DETAILED DESCRIPTION

[0022] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only some of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0023] Example 1

[0024] like Figures 1 to 5 As shown, this embodiment designs a puncture fire extinguisher for fire fighting, including a puncture tube 2, a puncture head 1, a quick fire switch 5 and a quick connector 6 and other components.

[0025] The puncture tube 2 adopts a metal straight tube structure.

[0026] An impact seat 3 is provided in the middle of the puncture tube 2. The impact seat 3 can be a circular ring structure. When in use, the impact seat 3 is fixed on the puncture tube 2. An impact looper 4 is sleeved on the rear section of the puncture tube 2. The impact looper 4 can slide along the puncture tube 2 to impact the impact seat 3. The impact force applied by the impact looper 4 to the impact seat 3 can be transmitted to the puncture tube 2, and the puncture tube 2 pushes the puncture head 1 to drill through the wall or door panel. The impact looper 4 can be made of copper material, because copper is softer than steel and is not easy to deform the puncture tube 2, thereby protecting the puncture tube 2. The impact stroke of the impact loop 4 sliding along the puncture tube 2 should not be too short, so as to facilitate the impact loop 4 to obtain a faster impact speed and a greater impact force during the impact stroke, so that the puncture head 1 has enough energy to penetrate the wall; on the other hand, the impact stroke of the impact loop 4 should not be too long. When the impact stroke is too long, the overall equipment of the fire-fighting puncture fire extinguishing gun will be too large and difficult to carry, affecting the portability. The impact stroke of the impact loop 4 is generally 30-60cm.

[0027] The impact seat 3 is in a circular ring shape and is sleeved and fixed on the puncture tube 2.

[0028] The rear end of the puncture tube 2 is detachably connected to the rapid fire switch 5. Since the puncture tube 2 is a consumable part, it is designed to be a portable disassembly and replacement structure, which can save costs.

[0029] The puncture head 1 is coaxially fixed to the front end of the puncture tube 2. The puncture head 1 adopts a conical structure and is generally made of carbon steel and hardened to reduce deformation of the puncture head 1 when puncturing a wall or a door panel.

[0030] A water spray hole 21 is provided on the tube wall of the front section of the puncture tube 2, and the rear end of the puncture tube 2 is connected to the quick fire switch 5, and the rear end of the quick fire switch 5 is connected to the fire water pipe through the quick connector 6, so that water, foam fire extinguishing agent or other fire extinguishing liquid can pass through the fire water pipe, the quick connector 6, the quick fire switch 5 and the puncture tube 2 in sequence, and then be sprayed out from the water spray hole 21, so as to perform fire extinguishing operations on the inside of the door panel or the inside of the wall.

[0031] When the fire-fighting piercing fire extinguishing gun in this embodiment is used:

[0032] The DN65 model quick connector 6 is connected to the fire hose. When there is a fire source in a closed warehouse or a dead corner of a house, it is determined whether it is necessary to use other tools to pre-drill a hole according to the scene. If not, the front end of the puncture tube 2 of the puncture fire extinguisher can be directly aimed at the wall; during the puncture process, the firefighters use the impact loop 4 to assist in puncturing the wall, and after puncture, water or other liquids or foam fire extinguishing agents are injected into the wall through the water gun switch. In the later structure, the puncture head 1 is penetrated into the wall or door panel by the impact of the impact loop 4, so that water is then sprayed through the water spray hole 21 to achieve fire fighting in the confined space; when in use, it can not only drill through the wall and door panel to extinguish the fire in the confined space, but also directly penetrate the cotton stack, haystack, wood stack, grain stack, paper stack and other solid smoldering materials to extinguish the fire, thereby improving the fire fighting efficiency and the safety of firefighters. During the use of the piercing fire extinguisher, the piercing fire extinguisher in this embodiment is effective in extinguishing fires in enclosed spaces and stacks and dealing with smoldering fires. It is suitable for preventing flashovers and backdrafts in enclosed indoor fires where burning materials are close to doors and in multi-story or higher buildings.

[0033] One or more anti-skid grooves 22 are arranged on the tube wall at the front end of the puncture tube 2, and the anti-skid grooves 22 are annular grooves.

[0034] The rapid fire switch 5 includes a valve seat 53, a ball valve 56 and an operating handle 51; the ball valve 56 is rotatably arranged in the valve seat 53, and the operating handle 51 is U-shaped and fixed relative to the ball valve 56; when the operating handle 51 is rotated, the switch action of the ball valve 56 can be controlled. A front adapter 52 is arranged at the water outlet of the valve seat 53, and the front end of the front adapter 52 is provided with an internal thread and is threadedly connected to the rear end of the puncture tube 2; a valve rear connector 59 is arranged at the rear end of the valve rear connector 59, and a rear adapter 54 is arranged at the rear end of the valve rear connector 59, and a reducer 55 is connected to the rear end of the reducer 55, and a quick connector 6 is connected to the rear end of the reducer 55; a holding handle 57 is arranged at the lower part of the valve seat 53, and the holding handle 57 is connected to the valve seat 53 through a fixing screw 58.

[0035] Example 2

[0036] like Figure 3 and Figure 4 As shown, based on the structure of Example 1, this embodiment designs a triangular bracket that can be used with a fire-fighting piercing fire extinguishing gun.

[0037] The triangular bracket in this embodiment is used to support the puncture tube 2, and includes an outer sleeve 7, a telescopic foot rod 8, a foot pad 9, a lower seat plate 10, an upper seat plate 11, a ball head connector and a rotating mounting seat 13 and other components.

[0038] Three rotating mounting seats 13 are fixed to the lower surface of the lower seat plate 10 and are respectively connected to the three outer sleeves 7. A limit baffle 131 is provided on one side of the rotating mounting seat 13. When the outer sleeve 7 rotates outward and abuts against the limit baffle 131, the rotation position of the outer sleeve 7 can be limited. The outer sleeve 7 can be a square tube. The outer sleeve 7 can be rotated and unfolded in different directions relative to the lower seat plate 10.

[0039] A telescopic foot rod 8 is arranged in each outer sleeve 7, and the lower end of the telescopic foot rod 8 extends out from the lower end of the outer sleeve 7. A plurality of pin holes are arranged on the side walls of the outer sleeve 7 and the telescopic foot rod 8, and the outer sleeve 7 and the telescopic foot rod 8 can be fixed by a pin passing through the two.

[0040] The lower end of the telescopic foot rod 8 is rotatably connected to a foot 9; the lower surface of the foot 9 is flat, so that it is convenient to fit on the ground.

[0041] The upper seat plate 11 is connected to the upper side of the lower seat plate 10 through a ball joint connector, so that the upper seat plate 11 can pitch and rotate relative to the lower seat plate 10. A plurality of mounting holes are provided on the upper seat plate 11, and the puncture tube 2 of the fire-fighting puncture extinguishing gun is fixed to the upper seat plate 11 through parts such as a clamp.

[0042] When the fire-fighting piercing fire extinguisher pierces into a wall or door panel, the piercing fire extinguisher can be fixed by a triangular bracket, thereby achieving long-term fire extinguishing.

[0043] Example 3

[0044] like Figure 5 As shown, this embodiment designs a packaging box, which includes a lower box body 14, an upper cover body 15 and a sponge mold 16. The sponge mold 16 is provided with two grooves for respectively placing a tripod bracket and a fire-fighting piercing fire extinguishing gun.

[0045] The upper cover 15 is covered on the upper part of the lower box body 14, and a fastener can be provided at the connection between the lower box body 14 and the upper cover 15 to achieve relative fixation of the lower box body 14 and the upper cover 15.
