[0055] Please refer to Figures 1 to 6 , this embodiment provides a forest fire fighting remote water supply and drainage emergency rescue vehicle, including a chassis 1, a fuel generator 2, a hand pump 5, an engine 8, a gearbox 9, and a fire pump 7. The fuel generator 2, the engine 8, the gearbox 9, and the fire pump 7 are spacedly arranged on the chassis 1. The hand pump 5 is provided with a motor 6. The fuel generator 2 is connected to the motor 6 through a cable to supply electrical energy to the motor 6. The engine 8 is provided with a power take-off port 81. The power take-off port 81 is connected to the input end of the gearbox 9 through a transmission shaft 82. The output end of the gearbox 9 is in transmission connection with the fire pump 7. The fire pump 7 is a liquid surface pump.

[0056] The chassis 1, as the basic structure of the entire vehicle, is designed to be strong enough to bear the weight of the on-vehicle equipment, carry and support all other components, and have good ground adaptability to ensure stable driving under various terrain conditions.

[0057] The fuel generator 2 is the core of the power source and can generate sufficient electrical energy to supply the on-vehicle electric components. The fuel of the fuel generator 2 can be diesel or gasoline, and the specific selection depends on actual needs and available resources.

[0058] The fire pump 7 can handle large-flow liquid transportation and can overcome relatively high resistance (i.e., high lift), which means it can transport a large amount of water over a relatively long distance or at a relatively high altitude, which is crucial for quickly clearing a large amount of accumulated water. The fire pump 7 is a liquid surface pump, and the working part is separated from the liquid and located above the liquid surface. The liquid surface pump inputs the liquid into the pump body through a pipeline.

[0059] The hand pump 5 with a built-in motor (i.e., an electric hand pump 5) can provide additional drainage capacity, especially in cases where quick response or local drainage is required. The portability of the hand pump 5 enables it to be quickly deployed after the vehicle arrives at the scene, improving the overall operation efficiency.

[0060] The engine 8 is provided with a power take-off port 81, which is connected to the input end of the gearbox 9 through a transmission shaft 82. The power of the engine 8 is transmitted to the gearbox 9 through the power take-off port 81, and then the fire pump 7 is driven.

[0061] When the forest fire fighting remote water supply and drainage emergency rescue vehicle starts, the engine 8 transmits power to the gearbox 9 through the power take-off port 81. After speed regulation by the gearbox 9, it drives the fire pump 7 to operate. The high and low pressure fire pump 7 can be switched to large flow water supply to achieve drainage operation, or switched to small flow and high lift water supply to achieve long-distance and high altitude water supply in the forest, without the need to add an additional pressurizing device for pressurization, reducing the laying of water pipes. The fuel generator 2 supplies power to the motor of the hand pump 5, enabling it to quickly start working at any location. The hand pump 5 is very flexible and convenient for manual carrying, and is suitable for areas that are difficult for the chassis 1 to reach. The combined use of the fire pump 7 and the hand pump 5 not only improves the drainage speed but also can cope with different types of working environments, greatly enhancing the emergency response ability and work efficiency.

[0062] Please refer to Figure 1 and Figure 2 In this embodiment, the engine 8 itself is installed below the chassis 1, and the power take-off port 81 is located at the upper part of the engine 8. Maintenance personnel can easily access the power take-off port 81 and related connection parts without excessive disassembly of the components at the bottom of the vehicle, and it is also convenient to connect to the adjacent fire pump 7. Among them, the power take-off port 81 is a full power take-off, ensuring strong power output, which can effectively drive the high-power fire pump 7 to meet the drainage requirements of large flow and high lift.

[0063] Please refer to Figure 1 In this embodiment, the rated output power of the engine 8 is above 200KW, the rated power generation power of the fuel generator 2 is above 200KW, the rated power of the fire pump 7 is above 200KW, and the rated power of the hand pump 5 is below 100KW. Preferably, the rated output power of the engine 8 is 300KW, the rated power generation power of the fuel generator 2 is 300KW, the rated power of the fire pump 7 is 220KW, and the rated power of the hand pump 5 is 30KW. Such a configuration ensures that when the fire pump 7 and the hand pump 5 are operating at full load, the fuel generator 2 and the engine 8 can still provide sufficient power, and even have a certain margin to cope with emergencies or future possible power upgrade requirements.

[0064] Please refer to Figure 1, in this embodiment, the fire pump 7 is a high-low pressure fire pump 7, and its rated outlet pressure is above 0.8 Mpa (megapascal, pressure unit). The rated outlet pressure can be detected by a pressure sensor. When the fire pump 7 is in the rated power state and the outlet pressure is greater than or equal to 0.8 MPa, it can ensure that the fire pump 7 has a large lift and can perform remote water supply operations. When the fire pump 7 is in the rated state, its rated outlet pressure can be 0.8 MPa, 1.0 MPa, 1.5 MPa, 3.0 MPa, 3.5 MPa, 4.0 MPa, etc., depending on the actual requirements. Taking the rated outlet pressure of the fire pump 7 of 0.8 MPa as an example, in the case of changing the speed or pressure of the fire pump 7 to make the fire pump 7 in a light load state with its outlet pressure less than 0.8 MPa, such a technical solution also belongs to the protection scope of this application.

[0065] In a preferred embodiment, due to the complex terrain and high altitude of the forest, the forest fire area is wide and the performance requirements for the product are high. The forest fire fighting remote water supply and drainage emergency rescue vehicle can meet various scenarios such as forest fire fighting and other emergency rescue. The rated outlet pressure of the high-low pressure fire pump 7 is above 1 Mpa, and the rated flow rate is above 150 L / s (liters per second). By compressing the water medium, an extremely high pressure is formed in the pipeline to overcome the limitations of terrain and distance, and water medium with a flow rate of greater than or equal to 150 L / s can be supplied to the forest land 100 m (meters) high, significantly improving the fire extinguishing efficiency and rescue speed and reducing the losses caused by forest fires.

[0066] Or in another preferred embodiment, the rated outlet pressure of the high-low pressure fire pump 7 is above 4 Mpa, and the rated flow rate is above 20 L / s. Water medium with a flow rate of greater than or equal to 20 L / s can be supplied to the forest land 400 m (meters) high, overcoming the limitations of terrain and distance, significantly improving the fire extinguishing efficiency and rescue speed and reducing the losses caused by forest fires.

[0067] Please refer to Figure 1 and Figure 2 , in this embodiment, the output end of the transmission shaft 82 and the gearbox 9 is directly connected to the pump shaft of the fire pump 7, and the power take-off port 81 and the input end of the gearbox 9 are directly connected, ensuring that the input end of the gearbox 9 can quickly respond to the drive of the engine 8, which helps to improve the overall efficiency and reliability. The direct connection can be a flange connection, a key connection or a coupling connection. The flange connection realizes the connection between shafts by aligning two flange plates and fastening them with bolts. Figure 2The two ends of the transmission shaft 82 are respectively connected to the fire pump 7 and the power take-off port 81 through flange plates 83. Key connection is a method of torque transmission achieved by inserting a key between the shaft and the bush, such as the keyway of the gearbox 9 matching the key of the output shaft of the engine 8, and achieving the rigid connection of the two shafts through the action of the key. A coupling is used to connect the two shafts, allowing a certain degree of offset or vibration while transmitting torque.

[0068] Please refer to Figure 2 , in this embodiment, the engine 8 and the fire pump 7 are located at the front part of the chassis 1, and the engine 8 is located in front of the fire pump 7, which is beneficial to power transmission. Please refer to Figure 1 , the fuel generator 2 is located in the middle or rear part of the chassis 1, behind the fire pump 7, which can balance the front and rear weight distribution of the vehicle and further improve driving stability. The fuel generator 2 is separated from the engine 8 and is away from the area of potential fire sources, reducing the fire risk.

[0069] Please refer to Figure 4 and Figure 5 , in this embodiment, the forest fire remote water supply and drainage emergency vehicle further includes a hoisting device 3 for hoisting. The hoisting device 3 is installed on the chassis 1. The hoisting device 3 can hoist other emergency equipment, such as a small mobile pumping station, a suction pipe (which can be used in combination with the fire pump 7), etc., and can also load and unload other heavy materials on the site.

[0070] Please refer to Figure 5 , the hoisting device 3 includes a hoisting winch 32 and a boom mechanism 31. The boom mechanism 31 includes a boom 311 and a lifting assembly 312. The boom 311 and the lifting assembly 312 are provided on a base 313. The lifting assembly 312 is used to control the pitching of the boom 311 on the base 313. The hoisting winch 32 includes a power source, a drum 321 and a towing rope 322 wound around the drum 321. A hook 323 is provided at the end of the towing rope 322. The power source and the drum 321 are provided on the base 313, and the power source is connected to the drum 321 for driving the drum 321 to rotate. A pulley 324 for supporting the towing rope 322 is provided at the end of the boom 311 away from the lifting assembly 312.

[0071] The lifting assembly 312 controls the pitching angle of the boom 311 on the base 313 to achieve the height adjustment of the boom 311. This mechanism ensures that the hoisting device 3 can cover a wider operating range, and the hoisting requirements at both high and low positions can be met. The power source (motor or hydraulic motor) drives the drum 321 to rotate, and the towing rope 322 on the drum 321 is wound or released accordingly. When the towing rope 322 is wound, the hook 323 rises; when the towing rope 322 is released, the hook 323 descends. By controlling the retraction and release of the towing rope 322, the operator can precisely control the position of the hook 323 to achieve the stable hoisting of heavy objects.

[0072] Please refer to Figure 5 , in this embodiment, the hoisting device 3 further includes a slewing assembly 314. A base 313 is provided on the slewing assembly 314. The slewing assembly 314 is used to control the slewing of the base 313, the boom 311 and the lifting assembly 312. The slewing assembly can achieve 360-degree free rotation, enabling the base 313, the boom 311 and the lifting assembly 312 to rotate omnidirectionally in the horizontal direction.

[0073] Please refer to Figure 5 , in this embodiment, the slewing assembly 314 includes a slewing bearing, a slewing drive (such as an electric motor or a hydraulic motor) and a speed reducer. The slewing bearing is the core component of the slewing base 313. It can bear the weights of the base 313, the boom 311 and the lifting assembly 312, while ensuring smooth and precise rotational movement. The slewing drive device drives the slewing bearing to rotate through the speed reducer, thereby driving the boom 311 and the lifting assembly 312 mounted thereon to rotate in the horizontal direction.

[0074] Please refer to Figure 5 , in this embodiment, the boom 311 includes a multi-stage telescopic boom 3111 and a linear motion member 3112. The multi-stage telescopic boom 3111 is provided on the base 313 and its length is telescopic. The linear motion member 3112 (the first linear motion member 3112) is provided on the multi-stage telescopic boom 3111 and is used to control the telescoping of the multi-stage telescopic boom 3111. The multi-stage telescopic boom 3111 is formed by mutually sliding and sleeving of multi-stage support arms. The linear motion member 3112 can be a component such as an oil cylinder, a cylinder, or an electric push rod that can be telescoped in a straight line direction. It is arranged along the length direction of the multi-stage telescopic boom 3111 to push the two support arms connected thereto to telescope, realizing the elongation or shortening of the multi-stage telescopic boom 3111.

[0075] Please refer to Figure 5 , in this embodiment, the lifting assembly 312 includes a second linear motion member. The lower end of the multi-stage telescopic boom 3111 is hinged to the base 313 through a lifting bracket. The multi-stage telescopic boom 3111 rotates up and down by virtue of the hinge point. One end of the second linear motion member is hinged to the lifting bracket, and the other end is hinged to the base 313. The second linear motion member can be a component such as an oil cylinder, a cylinder, or an electric push rod that can be telescoped in a straight line direction. Through its own telescoping, the lifting function of the multi-stage telescopic boom 3111 is realized. If the multi-stage telescopic boom 3111 has two telescopic arms, there is one second linear motion member, and one second linear motion member can drive two sections of the arm; if the multi-stage telescopic boom 3111 has three telescopic arms, there are two second linear motion members.

[0076] Preferably, the first linear motion member 3112 and the second linear motion member adopt electric cylinders, and their power is provided by a fuel-powered generator.

[0077] In some embodiments, the lifting assembly 312 rotates the multi-stage telescopic arm 3111 around the hinge point between the multi-stage telescopic arm 3111 and the base 313 by means of a motor.

[0078] In this embodiment, the hoisting winch 32 is an electric winch, that is, the power source is a motor. The fuel generator 2 is connected to the power source through a cable to supply electrical energy to the motor. As the main power source of the forest fire fighting remote water supply and drainage emergency vehicle, the electrical energy generated by the fuel generator 2 is transmitted to the power source in the form of a motor through a cable, and the power source drives the reel 321 to rotate, thereby realizing the retraction and release of the towing line.

[0079] Please refer to Figure 5 , in this embodiment, the towing rope 322 usually uses steel wire rope as the preferred material. The steel wire rope is made by twisting multiple strands of steel wires. Each steel wire itself has a very high tensile strength, and the combination of multiple strands of steel wires enables the steel wire rope to withstand extremely large tensile forces, making it very suitable for hoisting heavy objects.

[0080] Please refer to Figure 1 and Figure 4 , in this embodiment, the forest fire fighting remote water supply and drainage emergency vehicle further includes a carriage 4, and the carriage 4 is arranged on the chassis 1 to cover the fuel generator 2 and the fire pump 7. The carriage 4 provides a closed environment to protect the fuel generator 2 and the fire pump 7 from the influence of external environmental factors (such as rain, snow, dust, foreign objects, etc.). The door of the carriage 4 can be opened and closed, which is convenient for the maintenance and inspection of the equipment.

[0081] In this embodiment, there are two situations for the setting of the hoisting device 3. One is that the hoisting device 3 is arranged on the carriage 4. Specifically, the base 313 of the hoisting device 3 can be installed on the top of the carriage 4, making use of the structure of the carriage 4 as the support of the hoisting device 3, reducing the occupation of the space of the chassis 1. The structure is as shown in Figure 1 and Figure 4 . The other is that the base 313 of the hoisting device 3 is arranged on the chassis 1, and the carriage 4 should be provided with a reserved space for the boom of the hoisting device 3 to extend, ensuring that the boom of the hoisting device 3 can extend freely without being hindered by the structure of the carriage 4.

[0082] In this embodiment, the carriage 4 is detachably connected to the hand pump 5, and the hand pump 5 can be hung on the wall of the carriage 4 during non-operation periods. The detachable connection can be a snap connection or a strap connection. When the hand pump 5 needs to be used, the operator only needs to untie the strap or loosen the aviation buckle, and then can easily take out the hand pump 5 from the carriage 4 and bring it to the operation site, greatly enhancing the portability and flexibility of the hand pump 5.

[0083] Please refer to Figure 6, in this embodiment, expansion boxes 10 are provided on both sides of the carriage 4. The expansion boxes 10 can be used to place various devices. The devices can be stored in the expansion boxes 10. When these devices are needed, the expansion boxes 10 can be pulled out from the body of the box or the doors of the expansion boxes 10 can be opened, and the devices can be taken out from the expansion boxes 10, which is convenient for the storage of each device and improves the space utilization rate inside the carriage 4. The structure of the expansion box 10 can refer to the patent with the application number 202221742598.8.

[0084] Please refer to Figure 3 , in this embodiment, the forest fire fighting remote water supply and drainage emergency vehicle further includes a vehicle motor control cabinet 11 and a water pump control cabinet 12. The fuel generator is connected to the motor control cabinet through a cable. The vehicle motor control cabinet 11 is connected to the water pump control cabinet 12 through a cable. The water pump control cabinet 12 is connected to the motor 6 and the hand pump 5 through a cable.

[0085] The vehicle motor control cabinet 11 serves as the center of the electrical system of the forest fire fighting remote water supply and drainage emergency vehicle, responsible for receiving the electric energy output by the fuel generator and distributing it to each subsystem through a cable.
