Description
Technical Field
[0001] The utility model relates to a front box module for a large-flow compressed air foam fire truck, belonging to the technical field of compressed air foam fire trucks. Background Art
[0002] Compressed air foam fire truck refers to a fire truck that uses compressed air foam for fire extinguishing. The fire truck is equipped with a tank and a compressed air foam device, wherein the tank includes a Class A foam tank containing Class A foam, a Class B foam tank containing Class B foam, and a water tank containing pure water; the compressed air foam device includes an air compressor unit, a fire pump, a foam pump unit, a mixer, and an electronic control unit; the air compressor unit includes an air compressor, an air compressor engine, and a fuel tank; the foam pump unit includes a foam pump and a foam pump power unit; the tank, the air compressor unit, the fire pump, the foam pump unit, and the mixer are connected by pipelines; and the electronic control unit is used to control the normal operation of the compressed air foam device. During operation, the water in the water tank enters the mixer through the pipeline under the action of the fire pump, the Class A foam in the Class A foam tank or the Class B foam in the Class B foam tank enters the mixer through the pipeline under the action of the foam pump, and the compressed air generated by the air compressor unit enters the mixer through the pipeline. The water, foam and compressed air are mixed in the mixer to form compressed air foam. The formed compressed air foam is transported to the external injector (foam gun, fire monitor, etc.) and sprayed out through the injector for fire extinguishing.
[0003] The front box module is an important part of the large-flow compressed air foam fire truck. The existing air compressor unit is an integrated setting, that is, the air compressor unit includes an air compressor box, an air compressor, an air compressor engine and a fuel tank. The air compressor, the air compressor engine and the fuel tank are all arranged in the air compressor box, so the fuel tank refueling port is arranged inside the air compressor box (as shown in the attached manual). Figure 7 As shown in the figure), when it is necessary to refuel the oil tank of the air compressor unit in the front box, the firefighters must tilt the cab of the chassis to perform the refueling operation. Tilt-over and retract the cab will delay the firefighting operation time, and after getting on and off the cab, the firefighters are prone to standing unsteadily, which is not only inconvenient for refueling, but also poses a safety hazard. In addition, the front box module of the existing large-flow compressed air foam fire truck is equipped with a maintenance cabin at the front of the front box. When performing routine maintenance, the entire top cover needs to be removed to enter the maintenance cabin of the front box module, and the top cover needs to be reinstalled after the maintenance is completed, which has the defects of being time-consuming and labor-intensive.

[0031] The front box 1 includes a front box frame 11, a closing plate 12 and a skirt plate 13. The chamber 1-1 and the inspection room 1-7 are arranged at the upper part of the front box frame 11, the notch 1-2 and the wheel arch 1-3 are arranged at the lower part of the front box frame 11, the closing plate 12 is arranged on the left and right sides of the inspection room 1-7, and the skirt plate 13 is arranged on the lower peripheral side of the front box frame 11.
[0032] The method of using the front box module in this embodiment is as follows:
[0033] See also Figure 6 As shown, the notches 1-2 on the front and rear sides of the front box 1 are snap-fitted onto the auxiliary beam 4 of the fire truck, and then the air compressor unit 2 is hoisted into the chamber 1-1 through the opening at the top of the front box 1, and then the top cover 1-5 is installed.
[0034] When the oil tank 2-2 of the air compressor unit 2 needs to be refueled, since the refueling port 2-3 is arranged on the left or right side of the air compressor housing 2-1 (the left side is taken as an example in the figure of this embodiment, but it can be the right side), and the refueling port 2-3 is connected to the oil tank refueling port 2-21 in the air compressor housing 2-1 through the oil pipe 2-4 (see Figure 4 As shown in the figure, a hook ladder seat 1-4 for hanging the hook ladder 3 is fixedly arranged on the side of the front box 1 facing the refueling port 2-3. Therefore, the firefighter only needs to connect the hook ladder 3 with the hook ladder seat 1-4 and then climb the hook ladder 3 to refuel the oil tank 2-2 located in the air compressor housing 2-1. There is no need to turn over the cab to enter the front box for refueling. When refueling is completed, the hook ladder 3 is removed and hung on the rear of the fire truck, which has the advantages of convenient refueling and good safety.
