Description

Technical Field

[0001] This utility model relates to the field of emergency rescue equipment technology, and in particular to a rescue power supply vehicle. Background Technology

[0002] The vehicle-mounted gas turbine power supply vehicle is equipped with a generator set powered by a gas turbine. The vehicle boasts advantages such as high power density, small size, light weight, high reliability, simple maintenance, low maintenance cost, outstanding load capacity, high-quality output power, and high mobility. With its good applicability and ability to operate outdoors, it can serve as emergency power supply equipment in fields such as communications, telecommunications, coal mines, oil fields, and nuclear power, playing a particularly important role in power restoration during sudden power outages.

[0003] Existing generator sets and power vehicles all use electric start, which is a single starting method. Once the battery is severely depleted, the generators cannot start. This is especially problematic during field rescue operations, as the inability to connect to the mains power will greatly affect the orderly conduct of rescue operations, impact the timeliness of rescue efforts, and prevent timely power support for rescue equipment and related areas. This could delay rescue opportunities and cause greater losses. Summary of the Invention

[0072] Please see Figures 1 to 5 This embodiment relates to an emergency power supply vehicle, wherein the emergency power supply vehicle in this embodiment is a vehicle-mounted gas turbine power emergency power supply vehicle. The emergency power supply vehicle in this embodiment has a power of up to 2000kW, which can meet the needs of high-power emergency power supply occasions, such as occasions where power supply is damaged due to earthquakes, typhoons, or power grid maintenance.

[0073] The emergency power supply vehicle in this embodiment includes a frame 1, a generator 2, a drive system 3, and a chassis power system 4. The frame 1 serves as the vehicle's framework, the base of the vehicle, supporting and connecting all assemblies to maintain their relatively correct positions and withstand various loads from both inside and outside the vehicle. The frame 1 is the fundamental support structure of the emergency power supply vehicle, providing load-bearing and stability functions. As the load-bearing foundation of the entire emergency power supply vehicle, the frame is made of high-strength metal materials, possessing good rigidity and stability. It supports and secures components such as the generator 2, drive system 3, and chassis power system 4, while also providing the frame structure for the vehicle's movement, ensuring that all components remain relatively stable during vehicle operation and preventing displacement or damage due to bumps, vibrations, or other factors. In this embodiment, the emergency power supply vehicle uses a wheeled chassis as its mobile carrier. The use of a wheeled chassis facilitates movement, transportation, and relocation, improving work efficiency.

[0074] Furthermore, the power generation device 2 is mounted on the vehicle frame 1. The power generation device 2 is the core device for the power supply vehicle to achieve power supply. The power generation device 2 is used to provide power to the emergency equipment (such as lighting) of the emergency power supply vehicle, or to external emergency equipment (such as electricity for daily life in the emergency area); or the power generation device 2 can simultaneously provide power to both the emergency equipment of the emergency power supply vehicle and external emergency equipment to ensure the orderly conduct of emergency operations.

[0075] Furthermore, the drive system 3 is connected to the power generation device 2, and the drive system 3 is used to provide power to the power generation device 2 to start the power generation device 2 and ensure that the power generation device 2 can start smoothly. The chassis power system 4 is connected to the drive system 3, and the chassis power system 4 is used to provide power to the drive system 3 to start the drive system 3.

[0076] Specifically, in this embodiment of the emergency power supply vehicle, during operation, the chassis power system 4 of the emergency power supply vehicle is activated, providing power to the drive system 3 to start the drive system 3. Then, the drive system 3 provides power to the generator 2 to start the generator 2. Finally, the generator 2 generates power to supply power to the emergency equipment on the emergency power supply vehicle and / or external emergency equipment. In this embodiment, the emergency power supply vehicle is powered by the chassis power system 4 to ensure that the generator 2 can start normally and generate electricity during emergency operations. This allows the generator 2 to operate without relying on batteries, ensuring the orderly conduct of emergency operations, improving the timeliness of emergency operations, and reducing losses.

[0077] Optionally, in some embodiments, such as Figure 3As shown, the chassis power system 4 includes a chassis engine 41 and a power take-off (PTO) 42, and the drive system 3 is a hydraulic drive system 3. The chassis engine 41 is connected to the PTO 42, and the PTO 42 is connected to the first hydraulic pump 32 of the hydraulic drive system 3 via a drive shaft. The first hydraulic pump 32 of the hydraulic drive system 3 is connected to the hydraulic motor 22 of the power generation device 2 via an oil circuit. The chassis engine 41 is the power source for vehicle operation and also one of the power sources for the first hydraulic pump 32 in the drive system 3. The chassis engine 41 generates power by burning fuel, driving the crankshaft to rotate and converting the chemical energy of the fuel into mechanical energy. The power of the chassis engine 41 is transmitted to the first hydraulic pump 32 through the PTO 42, driving the first hydraulic pump 32 to work, thereby providing power to the hydraulic motor 22 and starting the power generation device 2. The PTO 42 is a key component connecting the chassis engine 41 and the first hydraulic pump 32; it is mounted on the output shaft of the chassis engine 41 and is connected to the first hydraulic pump 32 via a drive shaft. The function of the power take-off unit 42 is to extract a portion of the power output from the chassis engine 41 and transmit it to the first hydraulic pump 32, so that the first hydraulic pump 32 can work normally under the drive of the chassis engine 41.

[0078] Optionally, in some embodiments, such as Figure 3 As shown, the power generation device 2 includes a gas turbine assembly 21, a hydraulic motor 22, and a generator assembly 23; the gas turbine assembly 21 is disposed on one side of the generator assembly 23, the hydraulic motor 22 is connected to the gas turbine assembly 21 in a driving connection, and the gas turbine assembly 21 and the generator assembly 23 are connected in a driving connection through a coupling 24.

[0079] Among them, the gas turbine assembly 21 is one of the power sources of the power generation unit 2. The gas turbine assembly 21 generates high-temperature and high-pressure gas by burning fuel (such as natural gas, diesel, etc.), which drives the turbine blades to rotate, thereby converting the chemical energy of the fuel into mechanical energy, and providing rotational power for the generator assembly 23.

[0080] The hydraulic motor 22 is connected to the gas turbine assembly 21 and plays a crucial role in the startup process. The hydraulic motor 22 can convert the pressure energy of hydraulic oil into mechanical energy, and through its connection with the gas turbine assembly 21, it drives the gas turbine crankshaft to rotate, thereby starting the power generation unit 2.

[0081] The generator assembly 23 and the gas turbine assembly 21 are connected by a coupling 24. When the gas turbine assembly 21 is running, it transmits mechanical energy to the generator assembly 23 through the coupling 24. The rotor inside the generator assembly 23 rotates in the stator magnetic field, converting mechanical energy into electrical energy according to the principle of electromagnetic induction, generating a stable alternating current output to provide power for emergency rescue operations.

[0082] Furthermore, the drive system 3 includes a hydraulic oil tank 31 and a first hydraulic pump 32; the hydraulic oil tank 31 and the first hydraulic pump 32 are connected by an oil circuit, the first hydraulic pump 32 is connected by an oil circuit to the hydraulic motor 22, and the hydraulic motor 22 is connected by a return oil circuit to the hydraulic oil tank 31, thereby forming a hydraulic oil circuit, and the chassis power system 4 is connected to the first hydraulic pump 32 for transmission.

[0083] The hydraulic oil tank 31 is the oil storage container for the entire hydraulic system. It is made of high-strength, corrosion-resistant materials and is used to store hydraulic oil. It provides hydraulic oil to the first hydraulic pump 32 and also plays a role in settling impurities and dissipating heat, ensuring the normal operation of the hydraulic system.

[0084] The first hydraulic pump 32 is connected to the power take-off (PTO) 42 of the chassis power system 4 and operates under the drive of the chassis power system 4. The first hydraulic pump 32 draws hydraulic oil from the hydraulic oil tank 31 and pressurizes it, so that the hydraulic oil is delivered to the hydraulic motor 22 through the oil circuit at a certain pressure and flow rate. The function of the first hydraulic pump 32 is to convert the mechanical energy of the chassis engine 41 into the pressure energy of the hydraulic oil, providing a power source for the hydraulic motor 22, thereby starting the generator 2.

[0085] The hydraulic oil tank 31 is connected to the first hydraulic pump 32 via an oil circuit, forming an oil inlet channel for the first hydraulic pump 32, ensuring that the first hydraulic pump 32 can draw hydraulic oil from the hydraulic oil tank 31. The first hydraulic pump 32 is connected to the hydraulic motor 22 via an oil circuit, delivering pressurized hydraulic oil to the hydraulic motor 22 to provide power to the hydraulic motor 22. The hydraulic motor 22 is connected to the hydraulic oil tank 31 via an oil circuit, allowing the hydraulic oil after the hydraulic motor 22 has worked to flow back to the hydraulic oil tank 31, forming a complete hydraulic oil circulation loop.

[0086] Specifically, in this embodiment of the emergency power supply vehicle, during operation, the chassis power system 4 of the emergency power supply vehicle is started. The power of the chassis engine 41 is transmitted to the first hydraulic pump 32 through the power take-off 42. The first hydraulic pump 32 draws hydraulic oil from the hydraulic oil tank 31 and pressurizes it, so that the hydraulic oil is delivered to the hydraulic motor 22 through the oil circuit at a certain pressure and flow rate. The function of the first hydraulic pump 32 is to convert the mechanical energy of the chassis engine 41 into the pressure energy of the hydraulic oil, providing a power source for the hydraulic motor 22, thereby starting the generator 2. Finally, the generator 2 performs power generation to provide power to the emergency equipment of the emergency power supply vehicle and / or external emergency equipment. In this embodiment, the emergency power supply vehicle is powered by the chassis power system 4 to ensure that the generator 2 can start normally and generate electricity during emergency operations, so that the generator 2 can start without relying on the battery, ensuring the orderly progress of emergency operations, improving the timeliness of emergency operations, and reducing losses.

[0087] Specifically, in this embodiment, such as Figures 1 to 5 As shown, the emergency power supply vehicle also includes an electric starting mechanism 5; the drive system 3 includes a hydraulic oil tank 31, a first hydraulic pump 32, a second hydraulic pump 33, and a first reversing valve 34; the hydraulic oil tank 31 is connected to the first hydraulic pump 32 via an oil circuit, the first hydraulic pump 32 is connected to the hydraulic motor 22 via an oil circuit, the hydraulic motor 22 is connected to the hydraulic oil tank 31 via an oil circuit, and the power take-off 42 of the chassis power system 4 is connected to the first hydraulic pump 32 via a transmission connection; the hydraulic oil tank 31 and the second hydraulic pump 33 are connected via a transmission connection. The second hydraulic pump 33 is connected to the hydraulic motor 22 via an oil circuit. A first directional valve 34 is located on the oil circuit between the hydraulic motor 22 and the first hydraulic pump 32 and the second hydraulic pump 33. The first directional valve 34 controls the flow of hydraulic oil from the first hydraulic pump 32 or the second hydraulic pump 33 to the hydraulic motor 22. Specifically, when the generator 2 is driven by the chassis power system 4, the first directional valve 34 controls the flow of hydraulic oil from the first hydraulic pump 32 to the hydraulic motor 22 to drive the hydraulic motor 22. When the generator 2 is driven by the electric starting mechanism 5, the first directional valve 34 controls the flow of hydraulic oil from the second hydraulic pump 33 to the hydraulic motor 22 to drive the hydraulic motor 22. The electric starting mechanism 5 is drively connected to the second hydraulic pump 33. In this embodiment, the first directional valve 34 is a solenoid directional valve.

[0088] The hydraulic oil tank 31 is the oil storage container for the entire hydraulic system. It is made of high-strength, corrosion-resistant materials and is used to store hydraulic oil. It provides hydraulic oil for the first hydraulic pump 32 and the second hydraulic pump 33, and also plays a role in settling impurities and dissipating heat to ensure the normal operation of the hydraulic system.

[0089] The first hydraulic pump 32 is connected to the power take-off (PTO) 42 of the chassis power system 4 and operates under the drive of the chassis power system 4. The first hydraulic pump 32 draws hydraulic oil from the hydraulic oil tank 31 and pressurizes it, so that the hydraulic oil is delivered to the hydraulic motor 22 through the oil circuit at a certain pressure and flow rate. The function of the first hydraulic pump 32 is to convert the mechanical energy of the chassis engine 41 into the pressure energy of the hydraulic oil, providing a power source for the hydraulic motor 22, thereby starting the generator 2.

[0090] The second hydraulic pump 33 is connected to the electric starting mechanism 5. When the chassis power system 4 cannot work or needs to be started silently, the electric starting mechanism 5 can drive the second hydraulic pump 33 to work. The second hydraulic pump 33 also draws out and pressurizes the hydraulic oil in the hydraulic oil tank 31 to provide power to the hydraulic motor 22, thereby starting the generator 2.

[0091] The first directional valve 34 is located in the oil circuit between the hydraulic motor 22 and the first hydraulic pump 32 and the second hydraulic pump 33. Its main function is to control the flow direction of hydraulic oil. By switching the working state of the first directional valve 34, the hydraulic oil can be selected to flow from the first hydraulic pump 32 or the second hydraulic pump 33 to the hydraulic motor 22, thereby realizing the switching between chassis power drive start and electric drive start modes to meet the start requirements in different scenarios.

[0092] Specifically, in this embodiment, such as Figures 1 to 5 As shown, during emergency rescue operations, the electric starting mechanism 5 is activated, which drives the second hydraulic pump 33 to work and switches the first reversing valve 34, allowing hydraulic oil to flow from the second hydraulic pump 33 to the hydraulic motor 22. The second hydraulic pump 33 extracts and pressurizes the hydraulic oil from the hydraulic oil tank 31, so that the hydraulic oil is delivered to the hydraulic motor 22 through the oil circuit at a certain pressure and flow rate. The function of the second hydraulic pump 33 is to convert the mechanical energy of the chassis engine 41 into the pressure energy of the hydraulic oil, providing a power source for the hydraulic motor 22, thereby starting the generator 2. Finally, the generator 2 performs power generation to provide power to the emergency rescue equipment of the emergency power vehicle or / and external emergency rescue equipment. When the electric starting mechanism 5 is depleted (battery 51 is depleted) and there is no external mains power, the chassis power system 4 of the emergency power supply vehicle is started. The power of the chassis engine 41 is transmitted to the first hydraulic pump 32 through the power take-off 42, and the first reversing valve 34 is switched, so that the hydraulic oil flows from the first hydraulic pump 32 to the hydraulic motor 22. The first hydraulic pump 32 draws out the hydraulic oil from the hydraulic oil tank 31 and pressurizes it, so that the hydraulic oil is delivered to the hydraulic motor 22 through the oil circuit at a certain pressure and flow rate. The function of the first hydraulic pump 32 is to convert the mechanical energy of the chassis engine 41 into the pressure energy of the hydraulic oil, providing a power source for the hydraulic motor 22, thereby starting the generator 2. Finally, the generator 2 performs power generation to provide power to the emergency equipment of the emergency power supply vehicle and / or external emergency equipment.

[0093] This embodiment of the emergency power supply vehicle is equipped with two starting methods for the generator 2: a chassis power system 4 and an electric starting mechanism 5. When the electric starting mechanism 5 is severely unable to start electrically, the first hydraulic pump 32 can be driven by the chassis power system 4, and the generator 2 can be started using the hydraulic drive system 3. When the chassis power system 4 fails or silent starting is required (such as at night to avoid noise interference during emergency rescue), the second hydraulic pump 33 can be started by powering the electric starting mechanism 5. The two starting methods are mutually redundant, avoiding the limitations of a single starting method, greatly improving the reliability of the emergency power supply vehicle in various complex environments, ensuring timely starting during emergency rescue, providing power support for rescue operations, ensuring the orderly conduct of rescue operations, improving the timeliness of rescue, and reducing losses.

[0094] Optionally, in some embodiments, such as Figure 4 and Figure 5 As shown, the electric starting mechanism 5 includes a motor 52 and a battery 51. The battery 51 is electrically connected to the motor 52, providing power to the motor 52 to start it. The motor 52 is connected to the second hydraulic pump 33 via a drive shaft to start the second hydraulic pump 33. Alternatively, in other embodiments, the electric starting mechanism 5 includes a motor 52 connected to the second hydraulic pump 33 to start it, and the motor 52 is electrically connected to an external power source to start itself.

[0095] Traditional power vehicles rely on onboard batteries to directly start generators. When the battery is depleted (e.g., capacity drops by 30%-50% in low temperatures) or fails due to aging, the starting success rate drops drastically. This embodiment uses a chassis engine 41 to drive a first hydraulic pump 32, switching a first directional valve 34 to allow hydraulic oil to flow from the pump to the hydraulic motor 22, converting mechanical energy into hydraulic energy. The hydraulic motor 22 then starts the gas turbine, eliminating reliance on battery power. Even when the battery is low (e.g., SOC < 40%), for example, after 72 hours of continuous field operation, even if the battery 51 is deeply discharged, the chassis engine 41 can still successfully start the generator 2, ensuring uninterrupted emergency power supply.

[0096] In this embodiment, the emergency power supply vehicle is equipped with two starting methods for the generator 2: a chassis power system 4 and an electric starting mechanism 5. When the on-board battery 51 is severely depleted and cannot be started electrically, the first hydraulic pump 32 can be driven by the chassis engine 41 to start the generator 2 using the hydraulic drive system 3. When the chassis engine 41 fails or requires silent starting (such as at night to avoid noise interference), the battery 51 can supply power to the electric motor 52 to drive the second hydraulic pump 33 to start the generator. The two starting methods are mutually redundant, avoiding the limitations of a single starting method, greatly improving the reliability of the power supply vehicle in various complex environments, ensuring timely starting during emergency rescue, providing power support for rescue operations, ensuring the orderly conduct of rescue operations, improving the timeliness of rescue, and reducing losses.
