Description

Technical Field

[0001] The utility model relates to the technical field of fire trucks, and in particular to a multi-working-mode forest fire truck. Background Art

[0002] As forest areas expand, so too do forest fires. These fires not only kill or injure trees, directly reducing forest area, but also severely damage forest structure and the environment, leading to imbalances in forest ecosystems, a decline in forest biomass, reduced productivity, a decrease in beneficial animals and birds, and even casualties among humans and livestock. High-intensity fires can damage the chemical and physical properties of the soil, reducing its water retention and permeability. This can raise groundwater levels in some forested and low-lying areas, leading to swamping. Furthermore, carbonization and warming of the soil surface accelerate drying in burned areas, leading to the growth of weeds, hindering forest regeneration or causing the replacement of low-value forests resistant to extreme ecological conditions. Current forest fire trucks only have one operating mode and cannot adapt to different firefighting modes. Utility Model Content

[0048] Example, see Figure 1 、 Figure 2 and Figure 3 , which is an embodiment of the present utility model, proposes a multi-working mode forest fire truck, including a chassis 1, a liquid tank 2, a delivery pump 3, a first water outlet joint 4, a first pressure regulating valve 5, a second water outlet joint 6, a first flow regulating valve 7, a reel 8, a fire hose 9, a second pressure regulating valve 10, and a second flow regulating valve 11. The liquid tank 2 is arranged on the chassis 1; the delivery pump 3 is arranged on the chassis 1, and the inlet end of the delivery pump 3 is connected to the liquid tank 2; one end of the first water outlet joint 4 is connected to the outlet end of the delivery pump 3, and the other end of the first water outlet joint 4 is used to be connected to the water hose; the first pressure regulating valve 5 is arranged on the first water outlet joint 4; one end of the second water outlet joint 6 is connected to the outlet end of the delivery pump 3, and the other end of the second water outlet joint 6 is used to be connected to the water hose; the first flow regulating valve 7 is arranged on the second water outlet joint 6; the reel 8 is rotatably arranged on the chassis 1; the fire hose 9 is coiled on the reel 8; the second pressure regulating valve 10 and the second flow regulating valve 11 are connected in series and connected between the inlet end of the fire hose 9 and the outlet end of the delivery pump 3.

[0049] In this embodiment, the chassis 1 is used to carry various equipment and components of the fire truck. The liquid tank 2 is used to store large quantities of fire extinguishing media, such as water, foam mixture, etc., and can hold 4,000 kg of water. The delivery pump 3 is used to transfer the fire extinguishing media from the liquid tank 2 to the first water outlet connector 4, the second water outlet connector 6, and the fire hose 9. The first and second water outlet connectors 4 and 6 are located on both the left and right sides of the chassis 1. Power is transmitted through a drive shaft on the chassis 1 to drive the delivery pump 3. The first and second water outlet connectors 4 and 6 are used to connect the water hoses to the delivery pump 3. The first pressure regulating valve 5 is used to regulate the water pressure in the first water outlet connector 4, thereby regulating the water pressure in the water hose connected to the first water outlet connector 4. The first flow regulating valve 7 is used to regulate the flow in the second water outlet connector 6, thereby regulating the flow in the water hose connected to the second water outlet connector 6. The reel 8 is used to wind and store the fire hose 9, which is used to transport the fire extinguishing media.

By coordinating the first pressure regulating valve 5, the first flow regulating valve 7, the second pressure regulating valve 10, and the second flow regulating valve 11, the first water outlet 4, the second water outlet 6, and the fire hose 9 can achieve different pressures and flow rates, creating three firefighting operating modes. For example, the first water outlet 4 outputs a constant pressure of 1.0 MPa and a flow rate of 42 L / s, suitable for urban firefighting; the second water outlet 6 outputs a constant pressure of 4.5 MPa and a flow rate of 7 L / s, suitable for delivering water to mountaintops or high-rise buildings; and the fire hose 9 outputs a constant pressure of 2.0 MPa and a flow rate of 10 L / s, suitable for situations where the fire hose 9 can be used directly for firefighting. When extinguishing a fire, the user can choose to connect the hose to the first water outlet 4 or the second water outlet 6, or use the fire hose 9 directly, depending on the fire situation. This allows for different operating modes to be selected for different firefighting conditions. This compact and flexible device can be used for both forest fire supply and urban firefighting. The length of the fire hose 9 is preferably 50 meters. It can be used by directly pulling it out without the operator having to combine the water hose and the water gun, thereby ensuring the flow rate and shortening the rescue time.

[0050] Further, if Figure 1 、 Figure 4 、 Figure 5 and Figure 6As shown, the fire monitor 12 is also included. The fire monitor 12 is mounted on the chassis 1, and the inlet end of the fire monitor 12 is connected to the outlet end of the delivery pump 3.

The fire monitor 12 is located above the pump room 13. Placing the delivery pump 3, the first water outlet connector 4, the second water outlet connector 6, the reel 8, the fire hose 9, the second pressure regulating valve 10, and the second flow regulating valve 11 in the pump room 13 can provide protection and make the fire truck more neat and beautiful. The fire monitor 12 is placed above the pump room 13 for convenient use.

[0052] Further, if Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown, the fire truck also includes a cab 14 and warning lights 15. Cab 14 is mounted on chassis 1 and located at the front end of chassis 1, with the liquid tank 2 located behind cab 14. Warning lights 15 are located above cab 14.

Sealing cover 17 is disposed at manhole 16 and is detachably connected to the manhole 16. Firefighters or maintenance personnel can enter and exit the liquid tank 2 through manhole 16 for maintenance or inspection. Sealing cover 17 is used to seal manhole 16, preventing the fire extinguishing medium inside the liquid tank 2 from leaking. Opening sealing cover 17 allows for convenient addition of fire extinguishing medium, such as water or a foam mixture, into the liquid tank 2. The inner diameter of sealing cover 17 is equal to the outer diameter of manhole 16, and sealing cover 17 is buckled onto the periphery of manhole 16 for a more effective seal.

[0054] Further, if Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, it also includes a first support frame 18, a second support frame 19, a connecting plate 20, a positioning rod 21, and a locking block 22. The first support frame 18 is arranged on the manhole 16 and is located on the periphery of one side of the manhole 16; the second support frame 19 is arranged on the manhole 16 and is located on the periphery of the other side of the manhole 16; the connecting plate 20 is arranged on the sealing cover 17, one end of the connecting plate 20 is hinged to the first support frame 18, and the other end surface of the connecting plate 20 has a slot 23; the lower end of the positioning rod 21 is hinged to the second support frame 19, and the upper end of the positioning rod 21 is engaged with the slot 23 after rotation; the locking block 22 and the upper end of the positioning rod 21 are detachably connected, and the lower end surface of the locking block 22 contacts the upper end surface of the connecting plate 20.

[0055] Remove the locking block 22 from the positioning rod 21, rotate the upper end of the positioning rod 21 away from the sealing cover 17, so that the positioning rod 21 is separated from the slot 23 on the connecting plate 20, and lift the end of the sealing cover 17 close to the positioning rod 21 to open the sealing cover 17 for maintenance or adding fire extinguishing medium. Close the sealing cover 17 to ensure that it fits tightly with the manhole 16, then rotate the positioning rod 21 into the slot 23 on the connecting plate 20 so that the positioning rod 21 is engaged with the slot 23, and then install the locking block 22, lock the locking block 22 and the upper end of the positioning rod 21 together, and ensure that the lower end face of the locking block 22 contacts the upper end face of the connecting plate 20 to prevent the positioning rod 21 from slipping out of the slot 23.
