[0034] The vehicle body 100 includes a chassis 110, and a trailer hook 120 is provided at the front end of the chassis 110; the trailer hook 120 is equipped with a hand brake; during driving, the trailer hook 120 can realize the function of synchronous braking and deceleration according to the braking of the vehicle in front, ensuring driving safety, and can also park on a slope. A plurality of tires 130 are symmetrically provided on both sides of the vehicle body 100, and the vehicle body 100 is provided with a fender 140 at a position above the tire 130. An installation area is provided on the vehicle body 100, and a foam ton barrel 150 is installed in the installation area, and the foam ton barrel 150 is provided with a liquid outlet 151; an operating platform 160 is provided at a position in front of the foam ton barrel 150 on the vehicle body 100; the foam ton barrel 150 of the present application can carry more than 3000L of foam liquid. The foam liquid carried in the prior art is limited, generally about 300L to 500L, and rarely meets more than 1000L.

[0035] A water delivery pipe 200 is arranged on the vehicle body 100; a water inlet 210 is provided at one end of the water delivery pipe 200, and the other end is connected to a self-priming foam-water dual-purpose fire monitor 220; a foam outlet 230 and a water outlet 240 are also provided on the water delivery pipe 200, and a proportional mixer 250 is provided at the foam outlet 230; the water delivery pipe 200 is also provided with a first valve 260 for controlling the on-off of the water delivery pipe 200 and the self-priming foam-water dual-purpose fire monitor 220, a second valve 280 for controlling the on-off of the foam outlet 230, and a third valve 290 for controlling the on-off of the water outlet 240; the first valve 260 is a gate valve.

[0036] The foam delivery pipe 300 is connected to the liquid outlet 151 of the foam barrel 150; the foam delivery pipe 300 is connected to the proportioning mixer 250 and the self-priming foam-water dual-purpose fire monitor 220 through a hose; the foam delivery pipe 300 is provided with a fourth control valve 310, a fifth control valve 320 and a sixth control valve 330 for controlling the connection and disconnection of the foam delivery pipe 300 with the liquid outlet 151, the proportioning mixer 250 and the self-priming foam-water dual-purpose fire monitor 220. In other words, the fourth control valve 310 is used to control the connection and disconnection of the foam delivery pipe 300 with the liquid outlet 151; the fifth control valve 320 is used to control the connection and disconnection of the foam delivery pipe 300 with the proportioning mixer 250, and the sixth control valve 330 is used to control the connection and disconnection of the foam delivery pipe 300 with the self-priming foam-water dual-purpose fire monitor 220.

[0037] The application is moved to the target location by a fire truck or a separate tractor. The water inlet 210 is connected to the pressure water supply of a fire hydrant or a fire truck through a water hose. The application has multiple fire extinguishing modes:

[0038] Mode 1: Open the first valve 260 to supply water to the self-priming foam-water dual-purpose fire monitor 220, so that the fire is extinguished by spraying water through the self-priming foam-water dual-purpose fire monitor 220, that is, Class A solid fire is extinguished by water.

[0039] Mode 2: Open the first valve 260, the fourth control valve 310 and the sixth control valve 330. At this time, the self-priming foam-water dual-purpose fire monitor 220 automatically absorbs the foam liquid in the barrel through the Venturi principle. In addition, water enters the self-priming foam-water dual-purpose fire monitor 220 from the water delivery pipe 200, so that the foam liquid and water are mixed to form a foam-water mixed liquid and sprayed through the self-priming foam-water dual-purpose fire monitor 220 to extinguish the fire. Thus, Class B liquid fires can be extinguished.

[0040] Mode 3: Open the third valve 290. At this time, a fire hose needs to be connected to a fire hose gun at the water outlet 240, so that water can be sprayed through the fire hose gun for close-range fire extinguishing or cooling.

[0041] Mode 4: Open the second valve 280 and the fifth control valve 320. At this time, the fire foam gun needs to be connected to the foam outlet 230 through an external fire hose. The proportioning mixer 250 automatically absorbs the foam liquid in the foam barrel 150 through the Venturi principle, mixes water and foam in a specified ratio (for example, 1%, 3%, or 6%), and outputs them to the foam gun, so that the foam-water mixture is sprayed through the fire foam gun to extinguish the residual fire at close range.

[0042] When extinguishing a fire, the self-priming foam-water dual-purpose fire monitor 220 can be operated by a firefighter standing on the operating platform 160, and the spraying direction of the self-priming foam-water dual-purpose fire monitor 220 can be adjusted by rotating it horizontally and at an elevation angle.

[0043] It can be seen that this embodiment can spray water or foam-water mixture, which can not only extinguish Class A solid fires, but also more dangerous Class B liquid fires; it can also be connected to an external fire hose or fire foam gun to extinguish residual fires at close range, thus adapting to various complex fire-fighting environments. In addition, this embodiment adopts a self-priming foam-water dual-purpose fire monitor 220, which is a self-priming structure and can absorb the foam stock solution in the foam barrel 150 by itself without the need for an external power source. This embodiment can be hung on the rear of a fire truck through a trailer hook 120 or mounted through a separate tractor head, and can move quickly.

[0044] The trailer can be towed by a fire truck or other tractor head, and can be quickly deployed using the onboard water supply system. It moves quickly and can be easily and quickly fine-tuned on site.

[0045] Furthermore, the water delivery pipe 200 is a T-shaped pipe, and the water delivery pipe 200 includes a horizontal first pipe 200a and a second pipe 200b vertically connected to the first pipe 200a, and water inlets 210 are provided at both ends of the first pipe 200a. In this way, when the flow rate of a single water inlet 210 is insufficient, the water inlets 210 at both ends can also be connected to a water hose to supply water. The water inlet pressure gauge 270 (described below) is arranged on the first pipe 200a. The foam outlet 230, the water outlet 240 and the self-priming foam-water dual-purpose fire monitor 220 are arranged on the second pipe 200b.

[0046] Furthermore, the present application also includes a limit assembly 400, which includes a first limit piece 410, two second limit pieces 420 and a third limit piece 430 connected to the vehicle body 100; the first limit piece 410 is set against the front side of the foam ton barrel 150, the two second limit pieces 420 are symmetrically arranged on the left and right sides of the foam ton barrel 150, and the third limit piece 430 is set against the rear side of the foam ton barrel 150; the third limit piece 430 is detachably connected between the two second limit pieces 420. Specifically, the limit assembly 400 in this embodiment can limit the foam ton barrel 150 in the installation area of ​​the vehicle body 100 to prevent the foam ton barrel 150 from shifting back and forth in the vehicle body 100 and causing an accident.

[0047] Furthermore, the end of the second stopper 420 is provided with a first fixing member 421 extending in the width direction of the vehicle body 100, and is fixedly connected to the third stopper 430 by a bolt 422. Specifically, when the foam barrel 150 needs to be replaced, the third stopper 430 can be removed by simply loosening the bolt 422, which is convenient and quick to operate.

[0048] Furthermore, the present application further includes a fixing belt 500, and the foam ton bucket 150 is connected to the vehicle body 100 through the fixing belt 500. Specifically, a hook is provided at the end of the fixing belt 500; through holes are symmetrically provided on the two second stoppers 420, and the hooks of the fixing belt 500 are respectively hooked in the through holes of the two second stoppers 420. In this way, after the foam ton bucket 150 is installed in the installation area, the foam ton bucket 150 is further fixedly connected to the vehicle body 100 through the fixing belt 500, so as to prevent the foam ton bucket 150 from tipping over or shifting during use.

[0049] Furthermore, the installation area is provided with a track extending along the length direction of the vehicle body 100; the bottom of the foam ton barrel 150 is provided with a slide rail that slides with the track. In this way, the track and the slide rail cooperate, making it more convenient and labor-saving to replace and install the foam ton barrel 150.

[0050] Furthermore, a liquid discharge port 340 is provided on the foam delivery pipe 300 , and a valve for controlling the opening and closing of the liquid discharge port 340 is also provided on the foam delivery pipe 300 .

[0051] When the valve is opened, the remaining foam liquid in the foam ton barrel 150 can be emptied. In this way, when replacing the foam ton barrel 150, the valve can be opened to empty the foam ton barrel 150, and then the fixing belt 500 can be untied to move the foam ton barrel 150 backwards and replace it with a new foam ton barrel 150. This facilitates the quick replacement of the foam ton barrel 150, which saves time and effort.

[0052] Furthermore, the present application also includes a water inlet pressure gauge 270 disposed on the water delivery pipe 200. Specifically, the water inlet pressure gauge 270 of this embodiment can monitor the water pressure of the water inlet 210, so that firefighters can know the water pressure in time and perform operations.

[0053] Furthermore, a guide wheel 170 with a folding function is provided near the front end of the vehicle body 100. The guide wheel 170 in this embodiment can assist in controlling the direction of the trailer, so that after arriving at the fire scene, the firefighters can push the trailer to the position closest to the fire point on site.

[0054] Furthermore, the present application also includes a plurality of leveling legs 180 with folding function arranged on both sides of the vehicle body 100. When the present application is moved into place, the leveling legs 180 can be extended to fix the present application to the ground and make the vehicle body 100 in a horizontal state, and then the fire can be extinguished.

[0055] Furthermore, the operating platform 160 is provided with an anti-skid pedal 161 and a handrail 162. Firefighters can stand on the operating platform 160 to extinguish fires, and the anti-skid pedal 161 plays an anti-skid role, and firefighters can hold on to the handrail 162 to maintain balance during the fire extinguishing process.

[0056] Further, a width indicator light 190 is provided at the end of the vehicle body 100. The width indicator light 190 is convenient for playing a warning role when traveling under insufficient light conditions, so as to avoid accidents caused by the inability of the following vehicle to distinguish the size of the trailer.

[0057] Furthermore, lifting rings are provided on both sides of the front and rear ends of the vehicle body 100. The provision of the lifting rings facilitates the trailer to meet the need of lifting to the cargo platform during transportation.

[0058] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods.
