Description

Technical Field

[0001] This invention relates to the field of fire rescue, and in particular to a portable water tanker fire truck and its operating method. Background Technology

[0002] Currently, water tanker fire trucks have two core shortcomings in terms of water supply and intake operations and functional adaptability: First, conventional fire trucks have limitations in water access. Besides their own water tanks, these fire trucks primarily rely on municipal fire hydrants or vacuum pumps to draw water from natural sources. However, in older residential areas and suburban industrial parks, they often face problems such as inadequate fire-fighting facilities and insufficient water in fire hydrants. Furthermore, the vacuum pumps themselves have performance limitations, making it impossible to perform large-drop water suction operations, thus limiting water access efficiency. Summary of the Invention

[0003] This invention provides a convenient water tanker fire truck and its operating method, which can solve the problems pointed out in the background art.

[0004] A portable water tanker fire truck includes a control system and a water supply system, wherein the control system includes: A power take-off (PTO), the input of which is connected to the engine, transmission, or vehicle driveshaft; and Hydraulic systems include hydraulic pumps, hydraulic motors, hydraulic lines, hydraulic tanks, and coolers; The power take-off unit has at least two output ends, one of which is connected to the main shaft of the hydraulic pump, and the other is connected to the input shaft of the vehicle fire pump. The water supply system includes a hydraulically powered floating submersible pump and a water supply unit that can be connected to the outlet pipe of the hydraulically powered floating submersible pump. The hydraulic oil tank is connected to the input end of the hydraulic pump. The high-pressure oil output by the hydraulic pump drives the hydraulic power floating submersible pump, which uses a hydraulic motor, through the hydraulic pipeline. The return port of the hydraulic power floating submersible pump is connected to the oil tank through the hydraulic pipeline and the cooler in sequence.

[0005] Preferably, the water supply unit is a water crane.

[0006] Preferably, the water supply unit includes: A bracket, which is mounted on the top or side of the fire truck via a mounting base; and The water distribution pipe is either attached to the outside of the bracket or located inside the bracket. The bracket is hinged to the mounting base, which is rotatably mounted on the fire truck so that the water supply unit can swing left and right and adjust its pitch.

[0007] Preferably, the outlet of the water distribution pipeline is connected to a flexible hose for supplying water to the fire trucks on the side.

[0008] Preferably, the water supply unit is connected to a three-way structure, which has three interfaces: the first interface is used to connect to the water supply belt of the hydraulically powered floating submersible pump, the second interface is connected to the water distribution pipeline, and the third interface is used for pressure relief.

[0009] Preferably, the three-way structure is equipped with three control valves for controlling the opening and closing of the three ports respectively.

[0010] Preferably, the fire truck has a storage compartment on its top for accommodating the fire hose.

[0011] A method for operating a portable water tanker fire truck includes the following steps: S1. Drive the fire truck to the designated fire and rescue location and ensure the vehicle is parked securely; S2. Select the power input method of the power take-off according to the vehicle configuration, and complete the docking of the power take-off with the power source; S3. Take out the hydraulic power floating submersible pump, and connect one end of the hydraulic power floating submersible pump hose to the outlet of the hydraulic power floating submersible pump, and connect the other end to the interface of the three-way structure of the water supply system. S4. Operate the hydraulic hose reel to release the hydraulic oil pipe and deploy the hydraulic power floating submersible pump into natural water sources such as rivers and lakes, ensuring that the hydraulic power floating submersible pump floats stably and that the inlet is completely submerged in the water. S5. The power take-off is activated by the control system, which drives the hydraulic pump spindle to rotate. The hydraulic pump draws hydraulic oil from the hydraulic oil tank through the hydraulic pipeline to establish the system working pressure. The high-pressure oil is delivered to the hydraulic motor of the hydraulic power floating submersible pump through the hydraulic system control, which drives the hydraulic power floating submersible pump to operate and draw water from the water source. S6. Select one of the following operating modes based on the usage scenario. Operation Method 1: Supply water to other fire and rescue vehicles If water hydrant supply is used: directly connect the top inlet of the water tank of other water tanker fire trucks to the water hydrant of this vehicle, open the water hydrant control valve, and replenish the water by the water flow delivered by the hydraulic power floating submersible pump. If a bracket-type water distribution pipeline is used for water supply: remove the hinged bracket from the vehicle compartment, unfold the water distribution pipeline, and connect the hose at the outlet of the water distribution pipeline to the inlet on the top of the water tank of the adjacent water tank fire truck to complete the water supply. Method 2: Directly carry out firefighting operations Connect the water hose of the hydraulic floating submersible pump to the water distributor, and connect the output end of the water distributor to the fire hose, fire nozzle or water cannon respectively. Method 3: Firefighting operations using vehicle-mounted fire pumps. The power take-off unit outputs power to the vehicle fire pump, which draws water from the vehicle's on-board water tank and delivers it to the fire hose or water cannon for firefighting operations. S7, Finishing: Fold the water roc back into its storage compartment; Turn off the power take-off, cut off the power to the hydraulic pump, and stop the operation of the hydraulic system; close all interface control valves.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: In addition to its own water storage tank and vehicle-mounted fire pump for fire fighting, the fire truck proposed in this invention is also equipped with a hydraulically driven floating submersible pump for water intake operations in long-distance scenarios with large elevation differences. The hydraulic pump obtains power through one of the following: shaft take-off, gearbox take-off, or engine take-off, eliminating the need for a separate motor or engine, thus reducing costs. Furthermore, the fire truck of the present invention is also equipped with a folding water crane, which can directly supply water to other fire and rescue vehicles or supply fire hoses, water guns, and water cannons for fire rescue through the water distributor after the hydraulically driven floating submersible pump takes water, thus enriching its functions.

Detailed Implementation

[0015] The following detailed description of a specific embodiment of the present invention is provided in conjunction with the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0016] Example 1 like Figure 1 and Figure 2As shown in the figure, this embodiment proposes a portable water tanker fire truck, including a control system and a water supply system. The control system includes a power take-off 1 and a hydraulic system. The hydraulic system includes a hydraulic pump 2, a hydraulic motor, a hydraulic oil tank, a cooler, and hydraulic pipelines 4. In addition, to facilitate the storage of water hoses, the fire truck in this embodiment has a storage compartment 5 on the top for accommodating water hoses, based on the existing design. In this embodiment, the input end of the power take-off 1 is connected to the engine, gearbox, or vehicle drive shaft. Those skilled in the art can choose according to actual needs, and there is no restriction on which one to use. In addition, this embodiment also includes a vehicle fire pump 15, and the power take-off 1 has at least two output ends, one of which is connected to the main shaft of the hydraulic pump 2, and the other output end is connected to the input shaft of the vehicle fire pump 15. The water supply system includes a hydraulically powered floating submersible pump 3 and a water supply unit that can be connected to the hydraulically powered floating submersible pump 3 via a water pipe. The hydraulic oil tank is connected to the input end of the hydraulic pump 2. The high-pressure oil output by the hydraulic pump 2 drives the hydraulic power floating submersible pump 3 to work through the hydraulic pipeline 4. The return oil port of the hydraulic power floating submersible pump 3 is connected to the oil tank through the hydraulic pipeline 4 and the cooler in sequence to realize hydraulic circulation. In this embodiment, a hydraulic hose reel 7 is installed on the fire truck for winding and unwinding hydraulic hoses. Its power source can be manual, hydraulically driven, or electric motor driven. The hydraulically powered floating submersible pump 3 of this embodiment can meet the water intake needs of natural water sources compared to the vacuum pump in the prior art.

[0017] The water supply unit in this embodiment is mainly used to deliver water extracted by the hydraulically powered floating submersible pump 3 to fire trucks that do not have long-distance pumping capabilities. The water supply unit in this embodiment can be a water crane 6, but other water supply methods are not limited.

[0018] In addition, Figure 1 The locations of the tools or equipment shown, such as hydraulic pump 2, hydraulic hose reel 7, and vehicle-mounted fire pump 15, can be adapted to the actual situation. Furthermore, the location of the water supply unit is not limited to... Figure 1 The position in the middle can also be adopted Figure 2 The position in the middle.

[0019] Example 2 This embodiment proposes a convenient water tanker fire truck based on embodiment one. The water supply unit of this embodiment is different from that of embodiment one. Specifically, the water supply unit of this embodiment includes a bracket 8 and a water distribution pipe 9. Among them, bracket 8 is installed on the top or side of the fire truck via mounting base 14; Among them, the bracket 8 is hinged to the mounting base 14, that is, the bracket 8 can be adjusted up and down, and the mounting base 14 can be rotatably mounted on the fire truck so that the water supply unit can swing left and right and adjust pitch. This embodiment takes the hinged connection to the top of the fire truck as an example, but it is not limited to the top or one side. Those skilled in the art can adapt and choose a suitable location according to the actual situation. The water distribution pipe 9 in this embodiment can at least meet the functions of connecting with the water pipe of the hydraulically powered floating submersible pump 3 and supplying water to the fire truck located on the side. This embodiment proposes the following two types of water distribution pipes 9, but is not limited to the following two types. Those skilled in the art can make adaptive modifications according to the actual situation. Specifically, the water distribution pipe 9 can be a pipe formed inside the support 8 or a water pipe hung outside the support 8; either method is acceptable. To facilitate water supply, the outlet of water distribution pipe 9 is connected to a flexible hose for supplying water to the fire trucks on the side. In addition, the water supply unit is connected to a three-way structure with three interfaces. The first interface is used to connect to the water hose of the hydraulically powered floating submersible pump 3, the second interface is connected to the water distribution pipe 9, and the third interface is used for pressure relief.

[0020] The three-way structure is equipped with three control valves for controlling the opening and closing of the three ports respectively: control valve 10, control valve 21, and control valve 32.

[0021] Example 3 This embodiment proposes a convenient method for operating a water tanker fire truck, which specifically includes the following steps: S1. Drive the fire truck to the designated fire and rescue location and ensure the vehicle is parked securely; S2. Select the power input method of the power take-off according to the vehicle configuration, and complete the docking of the power take-off with the power source; S3. Take out the hydraulic power floating submersible pump, and connect one end of the hydraulic power floating submersible pump hose to the outlet of the hydraulic power floating submersible pump, and connect the other end to the interface of the three-way structure of the water supply system. S4. Operate the hydraulic hose reel to release the hydraulic oil pipe and deploy the hydraulic power floating submersible pump into natural water sources such as rivers and lakes, ensuring that the hydraulic power floating submersible pump floats stably and that the inlet is completely submerged in the water. S5. The power take-off is activated by the control system, which drives the hydraulic pump spindle to rotate. The hydraulic pump draws hydraulic oil from the hydraulic oil tank through the hydraulic pipeline to establish the system working pressure. The high-pressure oil is delivered to the hydraulic motor of the hydraulic power floating submersible pump through the hydraulic system control, which drives the hydraulic power floating submersible pump to operate and draw water from the water source. S6. Select one of the following operating modes based on the usage scenario. Operation Method 1: Supply water to other fire and rescue vehicles If water hydrant supply is used: directly connect the top inlet of the water tank of other water tanker fire trucks to the water hydrant of this vehicle, open the water hydrant control valve, and replenish the water by the water flow delivered by the hydraulic power floating submersible pump. If a bracket-type water distribution pipeline is used for water supply: remove the hinged bracket from the vehicle compartment, unfold the water distribution pipeline, and connect the hose at the outlet of the water distribution pipeline to the inlet on the top of the water tank of the adjacent water tank fire truck to complete the water supply. Method 2: Directly carry out firefighting operations Connect the water hose of the hydraulically powered floating submersible pump to the water distributor, and connect the output end of the water distributor to the fire hose, water gun or water cannon respectively. Method 3: Firefighting operations using vehicle-mounted fire pumps. The power take-off unit outputs power to the vehicle fire pump, which draws water from the vehicle's on-board water tank and delivers it to the fire hose or water cannon for firefighting operations. S7, Finishing: Fold the water roc back into its storage compartment; Turn off the power take-off, cut off the power to the hydraulic pump, and stop the operation of the hydraulic system; close all interface control valves.

[0022] Example 4 like Figure 5 As shown, this embodiment proposes a portable water tanker fire truck based on embodiment one or embodiment two. Its water supply unit includes a bracket 8 and a water distribution pipe 16. The bracket 8 is installed on the top or side of the fire truck through the mounting seat 14 so that the water supply unit can swing left and right and adjust pitch. Specifically, the mounting base 14 is rotatably connected to the water pipe 17 of the three-way structure. The water pipe of the three-way structure is vertical, so the mounting base 14 and the bracket 8 can swing left and right in the horizontal direction. The mounting base 14 has a horizontal branch pipe 16, and the bracket 8 is rotatably set on the branch pipe 16. The bracket 8 can rotate about the central axis of the branch pipe 16, thereby realizing the adjustment of the pitch angle. The three-way water pipe 17 has a rotary sealing joint connected to the mounting base 14. The mounting base 14 is laterally connected to the branch pipe 16. The bracket 8 has a rotary sealing joint connected to the branch pipe 16. This allows for angle adjustment while preventing water leakage. In other embodiments, to prevent the position of the water supply unit from changing due to external forces when supplying water to other fire trucks, movable parts are provided on the top of the mounting base 14 and one side of the bracket 8. The mounting base 14 and bracket 8 are each provided with a through groove that mates with the movable parts. A sealing ring is provided on the portion of the movable part located within the through groove. Additionally, baffles that are fixedly connected to the fire trucks are provided at the positions corresponding to the two movable parts. During water supply, the pressure inside the mounting base 14 and bracket 8 increases, and the water flow direction is towards the two movable parts, causing the movable parts to move outwards and abut against the baffles. The opposing sides of the baffles and movable parts are rough surfaces, thereby increasing the resistance to rotation of the mounting base 14 and bracket 8. This prevents the water supply unit from changing position due to external forces during water supply, thus ensuring it can properly supply water to other fire trucks. After water supply is completed, pressure is released through one of the valves in the three-way structure, and the movable parts reset. If they cannot reset automatically, they can be manually pressed to reset, allowing the bracket 8 to be folded and the overall height reduced.
