[0031] A fire extinguishing device for a rescue vehicle according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0032] Reference Figure 1 , the utility model aims to provide an embodiment of a fire extinguishing device for an emergency rescue vehicle.

[0033] In this embodiment, an emergency rescue vehicle mainly includes a vehicle body and a fire extinguishing device.

[0034] A fire extinguishing device for a rescue vehicle according to an embodiment of the present invention includes a lifting body, a connecting pipe 140 , a water hose 170 and a fire extinguishing gun 190 .

[0035] The lifting body includes a first folding arm 260 and a second folding arm 270 hinged to the first folding arm 260 . The second folding arm 270 is connected to the telescopic arm 100 .

[0036] It should be noted that, referring to Figure 1 and Figure 2 The first folding arm 260 has a first hydraulic rod, which is used to drive the second folding arm 270 to rise or fold. The second folding arm 270 has a second hydraulic rod, which is used to drive the telescopic arm 100 to rise or fold. The first folding arm 260 and the second folding arm 270 are both existing technologies and will not be repeated here.

[0037] Therefore, when the first folding arm 260 and the second folding arm 270 are folded, the lifting body occupies less space, so that the rescue vehicle can travel in a narrow road environment. At the same time, during fire extinguishing operations, the first folding arm 260 and the second folding arm 270 adjust the height position of the connecting pipe 140, which can change the height direction of the fire extinguisher 190, and can carry out targeted fire extinguishing operations.

[0038] Specifically, the telescopic arm 100 includes an outer tube 110 , a middle tube 120 and an inner tube 130 that are slidably connected. The middle tube 120 can extend from the inside of the outer tube 110 , and the inner tube 130 can extend from the inside of the middle tube 120 .

[0039] Therefore, the outer tube 110, the middle tube 120 and the inner tube 130 of the telescopic arm 100 slide relative to each other to change the length of the telescopic arm 100 itself, and the connecting tube 140 can follow the movement of the inner tube 130, so that the lifting body lifts the connecting tube 140 through the telescopic arm 100, and the connecting tube 140 is used to extinguish fires in low-rise buildings through the fire extinguishing gun 190.

[0040] Furthermore, the lifting body also includes a rotating platform 280, and the rotating platform 280 is connected to the first folding arm 260. The specific structure of the rotating platform is the existing technology and will not be repeated here.

[0041] Therefore, the rotating platform 280 can drive the first folding arm 260 to rotate horizontally, thereby making it possible to change the horizontal direction of the fire extinguishing gun 190 and perform targeted fire extinguishing operations.

[0042] Among them, the connecting pipe 140 is arranged inside the inner pipe 130, and the connecting pipe 140 extends along the length direction of the inner pipe 130. When the telescopic arm 100 is lifted, the lower end of the connecting pipe 140 is the first interface 150, and the upper end of the connecting pipe 140 is the second interface 160.

[0043] In some embodiments of the present invention, the connecting pipe 140 is made of stainless steel. Therefore, stainless steel is not easy to rust and is lightweight, which can reduce the weight borne by the telescopic arm 100 .

[0044] In some embodiments of the present invention, the length of the connecting tube 140 is smaller than the length of the inner tube 130, thereby avoiding interference between the connecting tube 140 and the outside, facilitating the lifting body to perform other functional operations, and enabling the lifting body to realize the function of lifting heavy objects.

[0045] In some embodiments of the present invention, a first fixing frame 200 is respectively provided at both ends of the connecting tube 140, and the upper and lower sides of the first fixing frame 200 respectively have a first vertical plate portion 210 and a second vertical plate portion 220, the first vertical plate portion 210 abuts against the upper side surface inside the inner tube 130, and the second vertical plate portion 220 abuts against the lower side surface inside the inner tube 130.

[0046] Therefore, when the connecting tube 140 is installed, the connecting tube 140 passes through the inner tube 130, and the first vertical plate portion 210 and the second vertical plate portion 220 respectively abut against the upper and lower sides of the inner tube 130. The first fixing frame 200 can lift the connecting tube 140 to ensure that the connecting tube 140 is close to the center position of the inner tube 130, thereby improving the stability of the telescopic arm 100 during movement.

[0047] In some specific embodiments of the present invention, refer to Figure 5 The first fixing frame 200 has an annular plate 250 , and the annular plate 250 is adapted to the outer surface of the connecting pipe 140 .

[0048] It should be noted that the annular plate 250 is welded to the outer surface of the connecting pipe 140 , so that the first fixing frame 200 is firmly installed on the connecting pipe 140 .

[0049] In some specific embodiments of the present invention, refer to Figure 5 There are two second vertical plate portions 220 , and the two second vertical plate portions 220 are arranged opposite to each other.

[0050] Therefore, when the connecting pipe 140 is installed, the connecting pipe 140 passes through the inner pipe 130 , and the second vertical plate portion 220 supports the connecting pipe 140 to prevent the connecting pipe 140 from rotating, making it easier to install and fix the connecting pipe 140 .

[0051] In a further embodiment of the present invention, a lifting ear 230 is provided on the inner side of the inner tube 130, and the lifting ear 230 is located between the two second vertical plate portions 220. A pin hole and a pin 240 inserted into the pin hole are provided between the lifting ear 230 and the second vertical plate portions 220, thereby making the installation structure of the connecting tube 140 simple and easy to install.

[0052] Among them, the water hose 170 is used to transport high-pressure fire extinguishing liquid, refer to Figure 3 and Figure 4 The water outlet end of the water hose 170 is provided with a first joint 180 , and the first joint 180 is connected to the first interface 150 .

[0053] Among them, the fire extinguisher 190 is used to output high-pressure fire extinguishing liquid, refer to Figure 3 and Figure 4 The water inlet end of the fire extinguisher 190 is provided with a second connector 290 , and the second connector 290 is connected to the second interface 160 .

[0054] In some embodiments of the present invention, the first connector 180 and the second connector 290 are both quick-press connectors. The specific structure of the quick-press connector is prior art and will not be described in detail herein.

[0055] Therefore, during the fire extinguishing operation, the water hose 170 is connected to the first socket through the quick-pressing connector, so that the water hose 170 is connected to the connecting pipe 140, and the fire extinguishing gun 190 is connected to the second socket through the quick-pressing connector, so that the fire extinguishing gun 190 is connected to the connecting pipe 140. When the fire extinguishing is completed, the water hose 170 and the fire extinguishing gun 190 can also be removed, thereby greatly improving the disassembly and assembly efficiency of the fire extinguishing device.

[0056] The working principle of a fire extinguishing device of an emergency rescue vehicle of the present invention is as follows: during fire extinguishing operations, the first folding arm 260 and the second folding arm 270 adjust the height position of the connecting pipe 140, which can change the height direction of the fire extinguishing gun 190. The rotating platform 280 can drive the first folding arm 260 to rotate horizontally, so that the horizontal direction of the fire extinguishing gun 190 can be changed, and the fire extinguishing operation can be carried out in a targeted manner. The outer tube 110, the middle tube 120 and the inner tube 130 of the telescopic arm 100 of the lifting body slide relative to each other to change the length of the telescopic arm 100 itself. The connecting pipe 140 can follow the movement of the inner tube 130, so that the lifting body lifts the connecting pipe 140 close to the fire source through the telescopic arm 100. The water hose 170 can transport high-pressure liquid to the connecting pipe 140, and the connecting pipe 140 outputs high-pressure liquid through the fire extinguishing gun 190, thereby enabling fire extinguishing work on low-rise buildings.
