Abstract
Description
Technical Field
[0001] This invention relates to an all-terrain vehicle, and more specifically, an all-terrain multi-functional fire and rescue vehicle. Background Technology
[0002] Fire and rescue vehicles are indispensable equipment in firefighting and rescue operations. Given my country's current development, fire problems are becoming increasingly complex and diverse. Firefighting and rescue operations are no longer limited to urban areas; complex terrains such as mountains and deserts also need to be considered. Traditional fire trucks are mostly modified from ordinary commercial chassis, which are generally adequate for tasks on flat ground. However, their ground clearance, mobility, and environmental adaptability are insufficient to meet the challenges of various terrains.
[0003] Discussions on the overall layout of fire trucks should be based on the location of the fire pump, classifying them into four types: front-mounted, center-mounted, rear-mounted, and side-mounted. Vehicles with a center-mounted fire pump offer advantages such as shorter transmission distance, higher efficiency, and more even axle load distribution. Rear-mounted fire trucks place the pump at the rear, facilitating maintenance and allowing for a smaller pump drive shaft angle. However, currently, various fire trucks generally suffer from exposed equipment, inadequate protection, unreasonable power distribution, and insufficient heat dissipation during prolonged high-load operation. Summary of the Invention

Detailed Implementation
[0017] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0018] like Figures 1 to 3 As shown, the all-terrain multi-functional fire and rescue vehicle includes a powertrain 1, which is connected to a front clutch unit 2 via a first coupling 11. The front clutch unit 2 is connected to a water pump 4. The powertrain 1 is connected to a rear clutch unit 3 via a second coupling 12. The rear clutch unit 3 is connected to a rear axle 5, which drives a pair of rear wheels 13.
[0019] This all-terrain multi-functional fire and rescue vehicle also includes a foot-operated accelerator (8) and a manual accelerator (9).
[0020] The all-terrain multi-functional fire and rescue vehicle can be in driving mode or working mode. When the all-terrain multi-functional fire and rescue vehicle is in driving mode, the foot accelerator 8 controls the output power of the powertrain 1. When the all-terrain multi-functional fire and rescue vehicle is in working mode, the manual accelerator 9 controls the output power of the powertrain 1.
[0021] It should be noted that the manual throttle 9 is located on the dashboard for easy operation.
[0022] The powertrain 1 is provided with a cooling water inlet pipe 14 and a cooling water outlet pipe 15. A main water tank 6 and an auxiliary water tank 7 are provided between the cooling water inlet pipe 14 and the cooling water outlet pipe 15. The main water tank 6 and the auxiliary water tank 7 are connected in series. A first fan 61 is provided on one side of the main water tank 6, and a second fan 71 is provided on one side of the auxiliary water tank 7.
[0023] It should be noted that both the main water tank 6 and the auxiliary water tank 7 are equipped with temperature sensors. This will be explained in more detail later.
[0024] like Figure 4 As shown, the front clutch unit 2 is an electronically controlled clutch.
[0025] The front clutch unit 2 includes a front clutch housing 21, which contains a front clutch input shaft 211, a first switching disk 22, and a second switching disk 23. The front clutch housing 21 is equipped with a solenoid valve 2 and a shift fork 25. The solenoid valve 2 drives the shift fork 25, causing the first switching disk 22 to engage or disengage from the second switching disk 23.
[0026] like Figure 5 As shown, the rear clutch unit 3 is equipped with a manual clutch lever 31. By manually shifting the manual clutch lever 31, the user can prevent power from being transmitted to the rear axle 5.
[0027] The all-terrain multi-functional fire and rescue vehicle includes a frame 100, on which a seat 101 is mounted, and a water pump 4 is located below the seat 101.
[0028] The water pump 4 has a water inlet 41 and a water outlet 42 on its outer side. The frame 100 has a fastening window 102 on its outer side, and a detachable fastening plate 103 on the fastening window 102. The fastening plate 103 faces the water inlet 41 and the water outlet 42. When the fire-fighting function is required, the fastening plate 103 can be quickly removed, which takes into account both concealment and ease of use.
[0029] The following describes the working method of this all-terrain multi-functional fire and rescue vehicle.
[0030] like Figure 6 As shown, if it is in driving mode, the main control unit switches the power control mode to foot accelerator 8. At the same time, the solenoid valve 2 is energized, and the first switching plate 22 is disengaged from the second switching plate 23. As a result, the power of the water pump 4 is cut off and it cannot be used. At this time, it can be driven normally.
[0031] To enter work mode, follow these steps: (1) Switch the vehicle to working mode by using the in-vehicle buttons located on the dashboard; (2) Manually operate the manual clutch lever 31 to cut off the driving force. At this time, the foot accelerator 8 will automatically become ineffective. (3) Shift the vehicle into L gear; (4) Remove the left-side buckle plate 103 and assemble the connecting water pipe; (5) Control the water pump flow rate by using the hand throttle 9 to complete the fire extinguishing work.
[0032] The rear clutch unit 3 ensures that, in operating mode, the engine's full actual power can directly drive the water pump, without wasting power due to driving transmission, and also prevents the vehicle from suddenly starting during firefighting operations, thus contributing to operational safety.
[0033] When the vehicle is to operate under high load for extended periods, both the main water tank 6 and the auxiliary water tank 7 operate simultaneously. This results in a large heat dissipation area and high cooling efficiency. To maintain electrical balance at low vehicle speeds, the system is specifically designed to activate the first fan 61 at approximately 87°C, and the second fan 71 only activates when the temperature reaches 90°C and the speed reaches 2500 rpm. The advantage of the dual-tank system is that it overcomes the space limitations of a single radiator, significantly increasing the total heat dissipation area without substantially increasing the size of individual radiators, thus ensuring the fire-fighting equipment's ability to operate continuously for extended periods. Furthermore, through flexible valve control, the system can adaptively adjust to different operating conditions, balancing economy and reliability.
[0034] This all-terrain multi-functional fire and rescue vehicle has a reasonable structure and good protective performance through the fully concealed arrangement of fire-fighting equipment. It can drive normally at the highest speed in driving mode and can also make full use of the water pump performance in working mode, and has the ability to carry out fire-fighting operations for a long time.
[0035] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
