[0060] See also Figures 1 to 11 , this embodiment provides a forest fire remote water supply and drainage rescue mother vehicle, including a sub-vehicle 2, a mother vehicle 1 and a portable pump 4;

[0061] A second motor 23 and a second high- and low-pressure fire pump 22 are provided on the second chassis of the sub-vehicle 2. The second motor 23 is in transmission connection with the second high- and low-pressure fire pump 22.

[0062] A power unit, a first high and low pressure fire pump 12, a vehicle motor control cabinet 13, a water pump control cabinet 14 and a winch 15 are provided on the first chassis 11 of the mother vehicle 1. The power unit is used to provide power for the second motor 23, the portable pump 4, the first high and low pressure fire pump 12, the vehicle motor control cabinet 13, the water pump control cabinet 14 and the winch 15. The second high and low pressure fire pump 22 and the portable pump 4 are all electrically driven. The power unit includes a generator 16 for powering the second high and low pressure fire pump 22 and the portable pump 4. The generator 16 is connected to the vehicle motor control cabinet 13 through a cable, and the vehicle motor control cabinet 13 is connected to the water pump control cabinet 14 through a cable. The water pump control cabinet 14 is connected to the second motor 23 and the portable pump 4 respectively through cables, and the winch 15 reels up the cable 27 between the water pump control cabinet 14 and the second motor 23.

[0063] See also Figure 4 The vehicle motor control cabinet 13 serves as the hub of the vehicle's electrical system, receiving the electrical energy output by the fuel generator 16 and distributing it to the various subsystems via cables. The water pump control cabinet 14 controls the operation of each electrically driven pump. It integrates a frequency converter, leakage protection device, relays, and other components, which work together to achieve precise control of the water pump system. For example, the frequency converter can adjust the voltage and frequency of the output power supply based on the internal IGBT's switching, providing the required power voltage according to the actual needs of the motor, thereby achieving energy conservation and speed regulation. When the system detects a leakage or short circuit, the leakage protection device automatically cuts off the circuit to prevent electric shock accidents and ensure the personal safety of the operator.

[0064] By combining the design of the mother vehicle 1 and the sub-vehicle 2, the flexibility of firefighting work in response to different terrain conditions is improved. The mother vehicle 1 can transport the sub-vehicle 2. When a forest fire or other emergency occurs, the mother vehicle 1 will carry the sub-vehicle 2 to the scene and use its powerful power unit to power itself and its ancillary equipment (such as the hand pump 4 and the second motor 23 of the sub-vehicle 2). Once it arrives at the destination, the sub-vehicle 2 can be deployed to a location closer to the fire scene or water source according to actual conditions. The first high and low pressure fire pump 12 and the second high and low pressure fire pump 22 can be switched to a large flow water supply to achieve drainage operations, or switched to a small flow and high head water supply to achieve long-distance and high-altitude water supply in the forest, without the need for additional pressurizing devices to increase pressure, reducing the laying of water pipes. If more flexible operation is required, the hand pump 4 can be used for auxiliary water supply. Throughout the process, the cable is properly managed through the winch 15 to ensure the safety and efficiency of power transmission.

[0065] See also Figure 1 and Figure 2 In this embodiment, there are two options for driving the fire pump of the mother vehicle:

[0066] The first option is to Figure 1 As shown, the first high- and low-pressure fire pumps 12 are electrically driven, powered by a generator 16. The water pump control cabinet 14 is connected to the first motor 18, and the first motor 18 is connected to the first fire pump via cables. In electric drive mode, the generator 16 generates electricity and transmits it to the vehicle motor control cabinet 13 via a cable system. This electricity is then distributed through the water pump control cabinet 14 to the first motor 18, enabling the pumps to operate.

[0067] The second option is to Figure 2 As shown, the power unit includes a first engine 17, which is provided with a power take-off port 171. The power take-off port 171 is transmission-connected (mechanically connected) to the first high- and low-pressure fire pumps 12. Specifically, the power take-off port 171 is connected to the input shaft of the first high- and low-pressure fire pumps 12 via a transmission shaft 172. The connection method can be a key connection or a flange connection. In this way, when the first engine 17 is running, power can be transmitted to the first high- and low-pressure fire pumps 12 through the power take-off port 171 to realize the operation of the pumps.

[0068] In this embodiment, due to the complex terrain and high altitude of the forest, the forest fire is widespread and the performance requirements of the product are high. The forest fire remote power supply and drainage rescue vehicle can meet various scenarios such as forest fire and other rescue and relief. The parameters of the first high and low pressure fire pump 12 have two options:

[0069] The first option is that the rated outlet pressure of the first high and low pressure fire pump 12 is above 1Mpa (megapascal, unit of pressure), and the rated flow rate is above 150L / s (liters per second). By compressing the water medium, it forms an extremely high pressure in the pipeline, overcoming the limitations of terrain and distance, and can supply a water medium greater than or equal to 150L / s to a forest 100m (meters) high, significantly improving the fire extinguishing efficiency and rescue speed, and reducing the losses caused by forest fires.

[0070] The second option is that the rated outlet pressure of the first high and low pressure fire pump 12 is above 4Mpa, and the rated flow rate is above 20L / s. It can supply water medium at a rate of 20L / s or more to the woodland at a height of 400m (meters), overcoming the limitations of terrain and distance, significantly improving the fire extinguishing efficiency and rescue speed, and reducing the losses caused by forest fires.

[0071] In this embodiment, the rated outlet pressure of the second high- and low-pressure fire pump 22 is greater than or equal to 0.8 MPa.

[0072] See also Figures 5 to 8In this embodiment, the second chassis includes a waterproof cabin 21 and a second running mechanism 26. The waterproof cabin 21 comprises a cabin body 211 and a cover plate 212. The second high- and low-pressure fire pumps 22 are mounted on the waterproof cabin 21. The cabin body 211 defines a cavity. The cover plate 212 is mounted on the cabin body 211 and covers the cavity. A sealing mechanism is provided between the cover plate 212 and the cabin body 211. The second running mechanism 26 is located on both sides of the cabin body 211 and is a tracked or wheeled running mechanism. The cabin body 211 is made of high-strength, corrosion-resistant material and has an internal cavity for accommodating key electronic components. The cover plate 212 is tightly attached to the cabin body 211 via a sealing structure, ensuring the cavity is sealed and preventing moisture from entering.

[0073] In this embodiment, the second chassis is designed with three different power configurations:

[0074] The first power configuration is, Figure 5 and Figure 7 As shown, a battery and a motor for driving the second walking mechanism 26 are provided in the cavity. The battery supplies power to the motor, thereby driving the second walking mechanism 26 to move on the ground.

[0075] The second power configuration is that the second chassis has its own power. A small second engine 17 is provided on the second chassis. The second engine 17 is connected to the second traveling mechanism 26 by transmission, that is, the second engine 17 transmits power to the track wheels or wheels of the second traveling mechanism 26 through mechanical transmission components.

[0076] The third power configuration is that the traveling power of the second chassis comes from the hydraulic station, which drives the hydraulic motor through the hydraulic oil to operate, and then drives the crawler wheels or wheels of the second traveling mechanism 26.

[0077] See also Figure 6 In this embodiment, the water inlet of the second high and low pressure fire pump 22 of the vehicle 2 can be connected to the water suction pipe 25. The water intake distance can be increased by pressurizing the second high and low pressure fire pump 22.

[0078] See also Figure 8 In this embodiment, at least one partition 213 is provided in the second chassis. The at least one partition 213 divides the cavity into at least two chambers. The battery and the third motor are located in different chambers. The second high and low pressure fire pump 22 is provided on the top of the cabin 211 through the pump bracket 24 and spans the cover plate 212. The second motor 23 is provided on the top of the cabin 211 through the motor bracket and spans the cover plate 212. The partition 213 and the cabin 211 are connected by welding, bolting or other reliable fixing methods to ensure their stability and sealing. The partition 213 will play a water-blocking role. In addition, the battery and the third motor will generate a lot of heat when working. Separating the two can maintain a good operating environment.

[0079] In this embodiment, there are two partitions 213 in the second chassis, which divide the cavity into a first chamber 2111, a second chamber 2112, and a third chamber 2113. The battery is arranged in the first chamber 2111, the controller is arranged in the second chamber 2112, and the third motor is arranged in the third chamber 2113. The cover 212 includes a first cover 2121 corresponding to the first chamber 2111, a second cover 2122 corresponding to the second chamber 2112, and a third cover 2123 corresponding to the third chamber 2113.

[0080] In this embodiment, there are at least two portable pumps 4. The portable pumps 4 are usually portable electric water pumps that can be quickly deployed near a water source to perform water pumping operations. Having multiple portable pumps 4 means that water supply operations can be performed simultaneously at different locations.

[0081] In this embodiment, the winch 15 can be driven in two different ways:

[0082] The first method involves electrically driving the winch 15, powered by a generator 16. The winch 15 is driven by a built-in electric motor. The generator 16, acting as a power source, supplies power to the motor via a cable. The motor, receiving power, rotates the winch 15, thereby retracting and extending the cable 27.

[0083] The second method is that the winch 15 is hydraulically driven, and the power unit also includes a hydraulic station, which provides hydraulic power for the winch 15. The hydraulic station consists of a hydraulic oil pump, an oil tank, a control valve, etc., and is used to generate and regulate hydraulic pressure. The high-pressure oil generated by the hydraulic station is transported to the hydraulic motor through a pipeline, driving it to operate, and then driving the winch 15 to work.

[0084] See also Figure 9 In this embodiment, the mother vehicle also includes a lifting device 3 for lifting. The lifting device 3 is arranged on the first chassis 11. The lifting device 3 can lift other rescue equipment, such as a small mobile pump station, a suction pipe 25 (which can be used in conjunction with a fire pump), etc., and can also load and unload other heavy materials on site.

[0085] See also Figure 10In this embodiment, the lifting device 3 includes a lifting 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 the base 313. The lifting assembly 312 is used to control the pitch of the boom 311 on the base 313. The lifting winch 32 includes a power source, a drum 321 and a traction rope 322 wound on the drum 321. The end of the traction rope 322 is provided with a hook 323. The power source and the drum 321 are provided on the base 313. The power source is connected to the drum 321 and is used to drive the drum 321 to rotate. A pulley 324 for supporting the traction rope 322 is provided at the end of the boom 311 away from the lifting assembly 312.

[0086] The lifting assembly 312 controls the pitch angle of the boom 311 on the first base 313 to achieve height adjustment of the boom 311. This mechanism ensures that the lifting device 3 can cover a wider operating range and can meet the lifting needs of both high and low places. The power source (motor or hydraulic motor) drives the drum 321 to rotate, and the traction rope 322 on the drum 321 is wound or released accordingly. When the traction rope 322 is wound, the hook 323 rises; when the traction rope 322 is released, the hook 323 drops. By controlling the retraction and release of the traction rope 322, the operator can accurately control the position of the hook 323 to achieve stable lifting of heavy objects.

[0087] See also Figure 10 In this embodiment, the traction rope 322 is usually made of steel wire rope as the preferred material. The steel wire rope is made of multiple strands of steel wires. Each steel wire itself has a high tensile strength, and the combination of multiple strands of steel wires enables the steel wire rope to withstand great tension, which is very suitable for lifting heavy objects.

[0088] See also Figure 10 In this embodiment, the arm 311 includes a multi-stage telescopic arm 3111 and a linear motion member 3112. The multi-stage telescopic arm 3111 is mounted on a base 313 and is extendable in length. The linear motion member 3112 (i.e., the first linear motion member 3112) is mounted on the multi-stage telescopic arm 3111 and is used to control the extension and retraction of the multi-stage telescopic arm 3111. The multi-stage telescopic arm 3111 is formed by slidingly connecting multiple arms. The linear motion member 3112 can be a linearly extendable component such as an oil cylinder, an air cylinder, or an electric push rod. It is arranged along the length of the multi-stage telescopic arm 3111 and pushes the two connected arms to extend and retract, thereby extending or shortening the multi-stage telescopic arm 3111.

[0089] In this embodiment, the lifting assembly 312 includes a second linear motion member. The lower end of the multi-stage telescopic arm 3111 is hinged to the base 313 via a lifting bracket. The multi-stage telescopic arm 3111 rotates up and down at 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 that can be telescopic in a linear direction, such as an oil cylinder, a pneumatic cylinder, or an electric push rod. This second linear motion member achieves the lifting function of the multi-stage telescopic arm 3111 through its own extension and retraction. If the multi-stage telescopic arm 3111 has two stages of telescopic arms, there is only one second linear motion member, and one second linear motion member can drive both arms. If the multi-stage telescopic arm 3111 has three stages of telescopic arms, there are two second linear motion members.

[0090] See also Figure 1 and Figure 2 In this embodiment, the mother vehicle 1 further includes a compartment 19, which is mounted on the first chassis 11 and houses the generator 16, the second high- and low-pressure fire pumps 22, the sub-vehicle 2, and the like. The compartment 19 provides a closed environment, protecting the generator 16 and the second high- and low-pressure fire pumps 22 from external environmental factors (such as rain, snow, dust, and foreign matter). The compartment 19 has an openable and closable door, facilitating equipment maintenance and inspection.

[0091] In this embodiment, there are two situations for the installation of the hoisting device 3. Figure 1 and Figure 2 As shown, the hoisting device 3 is provided on the carriage 19. Specifically, the base 313 of the hoisting device 3 can be installed on the top of the carriage 19, using the structure of the carriage 19 as the support of the hoisting device 3, reducing the space occupied by the first chassis 11. Figure 1 、 Figure 3 As shown. Figure 9 As shown, the base 313 of the lifting device 3 is arranged on the first chassis 11, and the carriage 19 should be provided with a reserved space for the lifting arm of the lifting device 3 to extend, ensuring that the lifting arm of the lifting device 3 can extend freely without being hindered by the structure of the carriage 19.

[0094] See also Figure 4 In this embodiment, the vehicle motor control cabinet 13 also features both mains power input and power generation output. The mains power input function allows forest fire remote power supply and drainage rescue vehicles to directly draw power from the mains in an environment with grid power. Through conversion and distribution by the vehicle motor control cabinet 13, the power is then supplied to the vehicle's electrical equipment. The power generation output function allows the vehicle motor control cabinet 13 to transmit power generated by the onboard generator 16 to external devices or other vehicles through a dedicated output interface, even providing power to residential communities, providing enhanced emergency response capabilities.

[0095] See also Figure 1 In this embodiment, the first chassis 11 has a first traveling mechanism, which is preferably a wheeled traveling mechanism.

[0096] The above technical solution has the following beneficial effects:

[0097] The first high and low pressure fire pump 12 and the second high and low pressure fire pump 22 can be switched to high flow water supply to realize drainage operations, or switched to low flow and high lift water supply to realize long-distance and high-altitude water supply in forests. There is no need to add additional pressure boosting devices to increase pressure, which reduces the laying of water pipes. The portable pump 4 is very flexible and easy to carry manually. It is suitable for areas that are difficult to reach with the chassis. The combined use of the fire pump and the portable pump 4 not only improves the drainage speed, but also can cope with different types of working environments, greatly improving the emergency response capability and work efficiency.
