[0027] Example

[0028] Please refer to Figure 1 and Figure 2 , Figure 1 FIG. 1 is a schematic structural diagram of a multi-gun multi-mode fire truck 100 provided in this embodiment at a first viewing angle. Figure 2 Shown is a schematic structural diagram of the multi-gun multi-mode fire truck 100 at a second viewing angle.

[0029] The multi-gun multi-mode fire truck 100 provided in this embodiment includes a vehicle body 110, a water system 120, a compressed air system 130, a foam system 140, a main gun mechanism 150 and a secondary gun mechanism 160. The water system 120, the compressed air system 130, the foam system 140, the main gun mechanism 150 and the secondary gun mechanism 160 are all arranged on the vehicle body 110; the main gun mechanism 150 is respectively connected to the water system 120, the compressed air system 130 and the foam system 140 through pipelines for spraying water and compressed air foam; the secondary gun mechanism 160 is respectively connected to the water system 120 and the foam system 140 through pipelines for spraying water and ordinary foam.

[0030] It can be understood that the ordinary foam referred to in this embodiment is opposite to the compressed air foam, and the ordinary foam refers to the foam output by the foam system 140 and not mixed with compressed air, while the compressed air foam refers to the product of the compressed air output by the compressed air system 130 and the foam output by the foam system 140. In the present application, the main gun mechanism 150 can spray both pure water and compressed air foam, and the secondary gun mechanism 160 can spray both pure water and ordinary foam.

[0031] In this embodiment, the main gun mechanism 150 and the secondary gun mechanism 160 are both arranged on the top of the vehicle body 110, and the connection position between the secondary gun mechanism 160 and the vehicle body 110 is closer to the front of the vehicle body 110 than the connection position between the main gun mechanism 150 and the vehicle body 110.

[0032] In order to obtain a wider spray angle, the main gun mechanism 150 and the secondary gun mechanism 160 are both arranged on the top of the vehicle body 110. And considering that the secondary gun mechanism 160 has a shorter range than the main gun mechanism 150, the secondary gun mechanism 160 is arranged closer to the front of the vehicle.

[0033] The vehicle body 110 includes a chassis, a car body and a sub-beam assembly. The car body and the sub-beam assembly are fixed on the chassis. The water system 120, the compressed air system 130 and the foam system 140 are all arranged on the chassis. The main gun mechanism 150 is arranged on the sub-beam assembly, and the sub-gun mechanism 160 is arranged on the car body.

[0034] It should be noted that, since the main gun mechanism 150 has a complex structure and a large weight, it is installed on the secondary beam assembly of the vehicle body 110 to ensure reliability. The secondary gun mechanism 160 has a relatively simple structure and a small weight, so it can be installed on the top of the vehicle body 110 to meet the force.

[0035] In fact, in other embodiments, the specific locations of the main gun mechanism 150 and the secondary gun mechanism 160 on the vehicle body 110 can be adjusted according to actual application conditions, and the locations of the two can even be interchanged. That is, the locations of the main gun mechanism 150 and the secondary gun mechanism 160 are not limited in this application.

[0036] In this embodiment, the main gun mechanism 150 includes a turntable assembly 151, an arm assembly 152 and a main gun 153. The turntable assembly 151 is arranged on the sub-beam assembly of the vehicle body 110, the arm assembly 152 is arranged on the turntable assembly 151, and is used to rotate in a horizontal plane driven by the turntable assembly 151. The main gun 153 is arranged on the arm assembly 152, and is used to adjust the spatial position driven by the arm assembly 152. The main gun 153 is connected to the water system 120, the compressed air system 130 and the foam system 140 respectively through pipelines.

[0037] In actual application, the turntable assembly 151 drives the cantilever assembly to rotate in the horizontal plane, thereby adjusting the spray angle of the main gun 153 in the horizontal plane. The arm assembly 152 can adjust the spatial position of the main gun 153, which means that the arm assembly 152 can drive the main gun 153 to rotate in the vertical plane to adjust the spray angle of the main gun 153 in the vertical plane, and adjust the distance of the main gun 153 relative to the vehicle body 110 in the vertical direction and the horizontal direction.

[0038] The boom assembly 152 includes a main arm 1521, a folding arm 1522 and a telescopic arm. One end of the main arm 1521 is hinged to the turntable assembly 151, one end of the folding arm 1522 is hinged to one end of the main arm 1521 away from the turntable assembly 151, the telescopic arm is telescopically arranged inside the folding arm 1522, and the telescopic end of the telescopic arm is connected to the main gun 153.

[0039] The arm assembly 152 also includes a main arm driving component 1523, a folding arm driving component 1524 and a telescopic driving component. The main arm driving component 1523 is respectively connected to the turntable assembly 151 and the main arm 1521, and is used to drive the main arm 1521 to rotate in a vertical plane relative to the turntable assembly 151; the folding arm driving component 1524 is respectively connected to the main arm 1521 and the folding arm 1522, and is used to drive the folding arm 1522 to rotate in a vertical plane relative to the main arm 1521; the telescopic driving component is respectively connected to the folding arm 1522 and the telescopic arm, and is used to drive the telescopic arm to slide relative to the folding arm 1522.

[0040] In this embodiment, the main arm driving member 1523, the folding arm driving member 1524 and the telescopic driving member are all oil cylinders, the fixed end of the main arm driving member 1523 is rotatably mounted on the turntable assembly 151, the telescopic end of the main arm driving member 1523 is rotatably connected to the main arm 1521, and the main arm driving member 1523 is in a vertical plane. When the active driving member is running, its telescopic end drives the main arm 1521 to rotate in the vertical plane relative to the turntable assembly 151, that is, adjusts the angle between the main arm 1521 and the horizontal plane.

[0041] The fixed end of the folding arm driving member 1524 is rotatably mounted on the main arm 1521, and its telescopic end is rotatably connected to the folding arm 1522, and the folding arm driving member 1524 is in a vertical plane. When the folding arm driving member 1524 is in operation, its telescopic end drives the folding arm 1522 to rotate in the vertical plane relative to the main arm 1521, that is, adjusts the angle between the folding arm 1522 and the main arm 1521.

[0042] The fixed end of the telescopic driving member is fixed on the folding arm 1522, and the telescopic end is connected to the telescopic arm, and the telescopic direction of the telescopic end of the telescopic driving member is the same as the extension direction of the folding arm 1522 and the telescopic arm. When the telescopic driving member is in operation, the telescopic arm is pushed out or pulled back along the folding arm 1522, that is, the length of the telescopic arm extending out of the folding arm 1522 is adjusted.

[0043] The secondary gun mechanism 160 includes a rotating seat 161 and a secondary gun 162. The rotating seat 161 is arranged on the carriage of the vehicle body 110. One end of the secondary gun 162 is connected to the rotating seat 161. The rotating seat 161 is used to drive the secondary gun 162 to rotate in a horizontal plane. The secondary gun 162 is respectively connected to the water system 120 and the foam system 140 through pipelines.

[0044] It can be understood that the rotating seat 161 drives the secondary gun 162 to rotate in the horizontal plane, that is, adjusts the spray angle of the secondary gun 162 in the horizontal plane. In this embodiment, the secondary gun mechanism 160 also includes a pitch drive member 163, which is connected to the rotating seat 161 and the secondary gun 162 respectively, and is used to drive the secondary gun 162 to rotate in the vertical plane relative to the rotating seat 161 to adjust the spray angle of the secondary gun 162 in the vertical plane.

[0045] In this embodiment, in the horizontal direction, the secondary gun mechanism 160 is located on one side of the main gun mechanism 150 , and a limiting bracket 111 is also provided on the top of the vehicle body 110 , and the limiting bracket 111 is used to stop the secondary gun mechanism 160 from rotating to collide with the main gun mechanism 150 .

[0046] It can be understood that the limiting bracket 111 is located on the horizontal rotation path of the secondary gun 162 and between the secondary gun 162 and the main gun mechanism 150. In the process of the secondary gun 162 being driven by the rotating seat 161 to rotate in the horizontal plane, when the secondary gun 162 rotates to abut against the limiting bracket 111, the limiting bracket 111 can prevent the secondary gun 162 from further rotating, thereby preventing the secondary gun 162 from colliding with the main gun mechanism 150.

[0047] In consideration of the protection of the secondary gun 162 , in this embodiment, the limiting bracket 111 is a rubber frame. When the secondary gun 162 rotates to abut against the rubber frame, the rubber frame can deform to absorb the kinetic energy of the secondary gun 162 to prevent the secondary gun 162 from being damaged.

[0048] In addition, in order to ensure that the vehicle body 110 is in a stable state during the spraying fire extinguishing process, the multi-gun multi-mode fire truck 100 provided in this embodiment also includes a leg support mechanism 170, which is arranged on the vehicle body 110. The leg support mechanism 170 is used to support the vehicle body 110 against the ground when the vehicle body 110 is in a parked state, so as to keep the vehicle body 110 stable.

[0049] In summary, in actual applications, the fire cannon provided in this embodiment, the main gun mechanism 150 and the secondary gun mechanism 160 can work together or selectively according to the actual scenario, is rich in functions, and can achieve higher fire extinguishing efficiency.

[0050] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
