Description

A remote-controlled water supply and drainage emergency vehicle for forest fire fighting Technical Field

[0001] This utility model relates to the field of emergency rescue equipment technology, and in particular to a remote water supply and drainage emergency rescue vehicle for forest fire fighting. Background Technology

[0002] As one of the most commonly used emergency rescue equipment, drainage trucks are frequently used for tasks such as drainage, flood control, and waterlogging control. They are also used for irrigation in agriculture and urban greening. When in use, drainage trucks use their onboard water supply and drainage devices to drain water from potholes, ditches, and rivers.

[0003] Existing drainage trucks have a large-flow drainage pump, but they have the disadvantage of low head. Without adding other pressurization devices, they cannot deliver the discharged water to distant high-altitude destinations. Their function is relatively simple and they are not suitable for complex emergency rescue environments, such as forest fire fighting. If drainage trucks are to be used for fire fighting, multiple drainage trucks need to be connected in series, which is very inconvenient. Utility Model Content

[0004] Therefore, it is necessary to provide a remote water supply and drainage emergency vehicle for forest fire fighting, which solves the problem that using drainage vehicles for fire fighting requires multiple drainage vehicles to be used in series, which is very inconvenient.

[0005] To achieve the above objectives, this embodiment provides a forest fire-fighting remote water supply and drainage emergency vehicle, including a daughter vehicle, a mother vehicle, and a hand pump;

[0006] The second chassis of the sub-vehicle is equipped with a second motor and a second high- and low-pressure fire pump, and the second motor is connected to the second high- and low-pressure fire pump.

[0012] The rated outlet pressure of the first high- and low-pressure fire pump is above 4 MPa, and the rated flow rate is above 20 L / s; or:

[0013] The rated outlet pressure of the second high- and low-pressure fire pump is greater than or equal to 0.8 MPa.

[0014] Furthermore, the second chassis includes a waterproof compartment and a second walking mechanism;

[0015] The waterproof compartment includes a compartment body and a cover plate. The second high and low pressure fire pump is installed on the waterproof compartment. The compartment body has a cavity. The cover plate is installed on the compartment body and covers the opening of the cavity. A sealing mechanism is provided between the cover plate and the compartment body. The second traveling mechanism is located on the left and right sides of the compartment body.

[0016] The cavity contains a battery and a third motor for driving the second walking mechanism; the battery powers the third motor. Alternatively:

[0017] The second chassis is equipped with a second engine, which is connected to the second walking mechanism via a transmission.

[0018] Furthermore, the second walking mechanism is a tracked walking mechanism, and there are at least two hand pumps.

[0019] Furthermore, the second chassis has at least one partition, which divides the cavity into at least two chambers, with the battery and the third motor located in different chambers. The second high and low pressure fire pump is mounted on the top of the cabin via a pump bracket and spans the cover plate. The second motor is mounted on the top of the cabin via a motor bracket and spans the cover plate.

[0020] Furthermore, the winch is electrically driven, and the generator supplies power to the winch; or:

The mother vehicle can transport the subsidiary vehicle, which will be dispatched to the scene in the event of a forest fire or other emergency, using its powerful motor to power itself and its auxiliary equipment (such as a portable pump and the subsidiary vehicle's second motor). Once at the destination, the subsidiary vehicle can be deployed closer to the fire or water source as needed. The second high- and low-pressure fire pump can be switched to high-flow water supply for drainage operations, or to low-flow, high-lift water supply for long-distance, high-altitude water supply in forests, eliminating the need for additional pressurization devices and reducing the need for pipe laying. For even more flexible operation, a portable pump can be used for auxiliary water supply. Throughout the process, cables are properly managed via winches, ensuring the safety and efficiency of power transmission. Attached Figure Description

[0060] Please refer to Figures 1 to 11. This embodiment provides a forest fire remote water supply and drainage emergency mother vehicle, including a daughter vehicle 2, a mother vehicle 1, and a hand pump 4.

[0061] The second chassis of the sub-vehicle 2 is equipped with a second motor 23 and a second high- and low-pressure fire pump 22, and the second motor 23 is connected to the second high- and low-pressure fire pump 22 in a transmission connection.

[0062] The first chassis 11 of the mother vehicle 1 is equipped with 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. The power unit provides power to the second motor 23, the hand 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 hand pump 4 are both electrically driven. The power unit includes a generator 16 that supplies power to the second high and low pressure fire pump 22 and the hand pump 4. The generator 16 is connected to the vehicle motor control cabinet 13 via a cable. The vehicle motor control cabinet 13 is connected to the water pump control cabinet 14 via a cable. The water pump control cabinet 14 is connected to the second motor 23 and the hand pump 4 via cables. The winch 15 winds up the cable 27 between the water pump control cabinet 14 and the second motor 23.

[0063] Please refer to Figure 4. The vehicle motor control cabinet 13, as the central hub of the main vehicle's electrical system, is responsible for receiving the electrical energy output from the fuel generator 16 and distributing it to various subsystems via cables. The water pump control cabinet 14 controls the operation of each electrically driven pump. It integrates frequency converters, leakage protection devices, relays, etc., working 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 according to the opening and closing of the internal IGBTs, providing the required power voltage according to the actual needs of the motor, thereby achieving energy saving and speed regulation. When the system detects leakage or short circuit, the leakage protection device will automatically cut off the circuit to prevent electric shock accidents and ensure the personal safety of operators.

[0064] By combining the design of the mother vehicle 1 and the daughter vehicle 2, the flexibility of firefighting operations under different terrain conditions is improved. The mother vehicle 1 can transport the daughter vehicle 2. In the event of a forest fire or other emergency, the mother vehicle 1 will carry the daughter vehicle 2 to the scene, using its powerful power unit to power itself and its auxiliary equipment (such as the portable pump 4 and the second motor 23 of the daughter vehicle 2). Once at the destination, the daughter vehicle 2 can be deployed to a location closer to the fire or water source, depending on the actual situation. The first high-low pressure fire pump 12 and the second high-low pressure fire pump 22 can be switched to high-flow water supply for drainage operations, or to low-flow, high-lift water supply for long-distance, high-altitude water supply in forests, without the need for additional pressurization devices, reducing the need for laying water pipes. If more flexible operation is required, the portable pump 4 can be used for auxiliary water supply. Throughout the process, the cable is properly managed through the winch 15, ensuring the safety and efficiency of power transmission.

[0065] Please refer to Figures 1 and 2. In this embodiment, there are two options for the fire pump drive method of the mother vehicle:

[0066] The first option, as shown in Figure 1, is that the first high- and low-pressure fire pump 12 is electrically driven, and the generator 16 supplies power to the first high- and low-pressure fire pump 12. The pump control cabinet 14 is connected to the first motor 18 via cables, and the first motor 18 is drive-connected to the first fire pump. In electric drive mode, the generator 16 generates electrical energy and transmits it to the vehicle motor control cabinet 13 through the cable system. Subsequently, the current is distributed to the first motor 18 through the pump control cabinet 14, enabling the pump to operate.

[0067] The second option, as shown in Figure 2, is a power unit comprising a first engine 17. The first engine 17 has a power take-off port 171, which is mechanically connected to the first high- and low-pressure fire pump 12. Specifically, the power take-off port 171 is connected to the input shaft of the first high- and low-pressure fire pump 12 via a drive shaft 172. The connection can be achieved via a key or a flange. In this way, when the first engine 17 is running, power can be transmitted to the first high- and low-pressure fire pump 12 through the power take-off port 171, thus enabling the pump to operate.

[0068] In this 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 remote power supply and drainage emergency vehicle can meet the needs of various scenarios such as forest fire fighting and other emergency rescue. The parameters of the first high and low pressure fire pump 12 can be selected in two ways:

[0069] The first option is to have a rated outlet pressure of over 1 MPa (megapascal, a unit of pressure) and a rated flow rate of over 150 L / s (liters per second) for the first high and low pressure fire pump 12. By compressing the water medium, it creates extremely high pressure in the pipeline, overcoming the limitations of terrain and distance. It can supply water medium with a flow rate of 150 L / s or more to forest land up to 100 m high, significantly improving 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 4 MPa and the rated flow rate is above 20 L / s. It can supply water medium with a flow rate of 20 L / s or more to forest land up to 400 m high, overcoming the limitations of terrain and distance, significantly improving 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-low pressure fire pump 22 is greater than or equal to 0.8 MPa.

[0072] Please refer to Figures 5 to 8. In this embodiment, the second chassis includes a waterproof compartment 21 and a second traveling mechanism 26. The waterproof compartment 21 includes a body 211 and a cover plate 212. The second high and low pressure fire pump 22 is mounted on the waterproof compartment 21. The body 211 has a cavity inside. The cover plate 212 is mounted on the body 211 and covers the opening of the cavity. A sealing mechanism is provided between the cover plate 212 and the body 211. The second traveling mechanism 26 is located on the left and right sides of the body 211. The second traveling mechanism 26 is a tracked traveling mechanism or a wheeled traveling mechanism. The body 211 is made of high-strength corrosion-resistant material, and an internal cavity is formed to accommodate key electronic components. The cover plate 212 is tightly fitted to the body 211 through a sealing structure to ensure the airtightness of the cavity and prevent moisture from seeping in.

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

[0074] The first power configuration is as shown in Figures 5 and 7, in which a battery and a motor for driving the second walking mechanism 26 are provided in the cavity. The battery powers the motor, thereby driving the second walking mechanism 26 to walk on the ground.

[0075] The second power configuration is that the second chassis is self-powered, and a small second engine 17 is installed on the second chassis. The second engine 17 is connected to the second walking mechanism 26 through a transmission mechanism. That is, the second engine 17 transmits power to the track wheels or wheels of the second walking mechanism 26 through mechanical transmission components.

[0076] The third power configuration is that the second chassis's walking power comes from a hydraulic station, which drives a hydraulic motor through hydraulic oil, thereby driving the track wheels or wheels of the second walking mechanism 26.

[0077] Please refer to Figure 6. In this embodiment, the water inlet of the second high and low pressure fire pump 22 of the sub-vehicle 2 can be connected to a water suction pipe 25. By pressurizing the second high and low pressure fire pump 22, the water intake distance can be increased.

[0078] Referring to Figure 8, in this embodiment, the second chassis has at least one partition 213, which 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 mounted on top of the cabin 211 via a pump bracket 24 and spans across the cover plate 212. The second motor 23 is mounted on top of the cabin 211 via a motor bracket and spans across 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 serves to block water. In addition, the battery and the third motor generate a lot of heat during operation; separating them helps maintain a good operating environment.

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

[0080] In this embodiment, there are at least two hand pumps 4. The hand pumps 4 are typically portable electric water pumps that can be quickly deployed near water sources for pumping operations. Having multiple hand pumps 4 means that water supply operations can be carried out simultaneously in different locations.

[0081] In this embodiment, the winch 15 can employ two different driving methods:

[0082] In the first method, the winch 15 is electrically driven, and the generator 16 supplies power to the winch 15. The winch 15 is driven by a built-in electric motor. The generator 16, as a power source, supplies power to the electric motor through a cable. After receiving power, the electric motor drives the winch 15 to rotate, thereby realizing the winding and unwinding of the cable 27.

[0083] The second method involves hydraulically driven winch 15, with the power unit also including a hydraulic station that provides hydraulic power to winch 15. This hydraulic station consists of a hydraulic pump, oil tank, control valves, etc., and is used to generate and regulate hydraulic pressure. The high-pressure oil generated by the hydraulic station is transported through pipelines to the hydraulic motor, driving it to operate, which in turn drives winch 15 to work.

[0084] Please refer to Figure 9. In this embodiment, the mother vehicle also includes a lifting device 3 for hoisting. The lifting device 3 is mounted on the first chassis 11. The lifting device 3 can lift other emergency equipment, such as small mobile pump stations, water suction pipes 25 (which can be used in conjunction with fire pumps), etc., and can also load and unload other heavy materials on site.

[0085] Please refer to Figure 10. In this embodiment, 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 mounted on a base 313. The lifting assembly 312 is used to control the pitch of the boom 311 on the base 313. The hoisting 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 mounted on the base 313 and connected to the drum 321 to drive the drum 321 to rotate. The end of the boom 311 away from the lifting assembly 312 is provided with a pulley 324 for supporting the traction rope 322.

[0086] The lifting assembly 312 controls the pitch angle of the boom 311 on the first base 313, thereby adjusting the height of the boom 311. This mechanism ensures that the lifting device 3 can cover a wider operating range, meeting lifting needs at both high and low altitudes. The power source (electric motor or hydraulic motor) drives the drum 321 to rotate, causing the traction rope 322 on the drum 321 to wind or unwind accordingly. When the traction rope 322 is wound, the hook 323 rises; when the traction rope 322 is unwinded, the hook 323 descends. By controlling the winding and unwinding of the traction rope 322, the operator can precisely control the position of the hook 323, achieving stable lifting of heavy objects.

[0087] Please refer to 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 wire twisted together. Each steel wire has a high tensile strength, and the combination of multiple strands of steel wire enables the steel wire rope to withstand great tension, making it very suitable for lifting heavy objects.

[0088] Please refer to Figure 10. In this embodiment, the boom 311 includes a multi-stage telescopic boom 3111 and a linear motion component 3112. The multi-stage telescopic boom 3111 is mounted on the base 313 and its length is telescopic. The linear motion component 3112 (i.e., the first linear motion component 3112) is mounted on the multi-stage telescopic boom 3111 and is used to control the extension and retraction of the multi-stage telescopic boom 3111. The multi-stage telescopic boom 3111 is formed by multiple stages of outriggers slidingly connected to each other. The linear motion component 3112 can be a component that can extend and retract in a straight line, such as a hydraulic cylinder, pneumatic cylinder, or electric actuator. It is arranged along the length direction of the multi-stage telescopic boom 3111 and pushes the two outriggers connected to it to extend and retract, thereby realizing the extension or retraction of the multi-stage telescopic boom 3111.

[0089] In this embodiment, the lifting assembly 312 includes a second linear motion component. 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 via the hinge point. One end of the second linear motion component is hinged to the lifting bracket, and the other end is hinged to the base 313. The second linear motion component can be a component that can extend and retract in a linear direction, such as a hydraulic cylinder, pneumatic cylinder, or electric actuator, and 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 telescopic arms, there is one second linear motion component, and one second linear motion component can drive two arm sections; if the multi-stage telescopic arm 3111 has three telescopic arms, there are two second linear motion components.

[0090] Referring to Figures 1 and 2, in this embodiment, the mother car 1 also includes a carriage 19, which is mounted on the first chassis 11 and shelters the generator 16, the second high- and low-pressure fire pumps 22, the daughter car 2, etc. The carriage 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, foreign objects, etc.). The doors of the carriage 19 can be opened and closed for easy maintenance and inspection of the equipment.

[0091] In this embodiment, the hoisting device 3 is configured in two ways. First, as shown in Figures 1 and 2, the hoisting device 3 is mounted on the carriage 19. Specifically, the base 313 of the hoisting device 3 can be installed on the top of the carriage 19, utilizing the structure of the carriage 19 as a support for the hoisting device 3, thus reducing the space occupied by the first chassis 11. The structure is shown in Figures 1 and 3. Second, as shown in Figure 9, the base 313 of the hoisting device 3 is mounted on the first chassis 11. The carriage 19 must have reserved space to facilitate the extension of the boom of the hoisting device 3, ensuring that the boom of the hoisting device 3 can extend freely without being obstructed by the structure of the carriage 19.

[0092] In this embodiment, the carriage 19 and the hand pump 4 are detachably connected, and the hand pump 4 can be hung on the wall of the carriage 19 during non-operational periods. The detachable connection can be a snap-on connection or a strap connection. When the hand pump 4 needs to be used, the operator only needs to untie the strap or loosen the aviation buckle to easily take the hand pump 4 out of the carriage 19 and take it to the work site, which greatly enhances the portability and flexibility of the hand pump 4.

[0093] Please refer to Figure 11. In this embodiment, the carriage 19 is provided with expansion boxes 191 on both sides. The expansion boxes 191 can be used to store various devices. The devices can be stored in the expansion boxes 191. When these devices are needed, the expansion boxes 191 can be pulled out from the main body of the carriage or the door of the expansion boxes 191 can be opened and the devices can be taken out from the expansion boxes 191, which facilitates the storage of various devices and improves the space utilization rate inside the carriage 19.

[0094] Referring to Figure 4, in this embodiment, the vehicle motor control cabinet 13 also has the functions of mains power input and generator output. The mains power input function allows the forest fire remote power supply and drainage emergency vehicle to directly obtain power from the mains in an environment with grid power supply, and provide power to the electrical equipment in the vehicle through the conversion and distribution of the vehicle motor control cabinet 13. The generator output function means that the vehicle motor control cabinet 13 can provide the power generated by the on-board generator 16 to external equipment or other vehicles through a dedicated output interface, and even provide power to the community, thus possessing better emergency response capabilities.

[0095] Please refer to Figure 1. In this embodiment, the first chassis 11 has a first walking mechanism, which is preferably a wheeled walking mechanism.

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

[0097] The first high-low pressure fire pump 12 and the second high-low pressure fire pump 22 can be switched to high flow water supply for flood drainage operations, or to low flow high head water supply for long-distance, high-altitude water supply in forests. No additional pressurization device is needed, reducing the need for laying water pipes. The portable pump 4 is very flexible and easy to carry manually, suitable for areas that are difficult for the chassis to reach. The combined use of the fire pumps and the portable pump 4 not only improves the drainage speed, but also can cope with different types of working environments, greatly improving emergency response capabilities and work efficiency.
