[0031] Embodiment

[0032] Such as Figure 1 And Figure 2As shown in the figure, an emergency power supply vehicle with a gas turbine type proposed by the utility model includes a Class II chassis vehicle 1. An installation base 2 is installed on the longitudinal beam of the Class II chassis vehicle 1. The installation base 2 includes a first chassis 21 fixedly installed on the longitudinal beam of the Class II chassis vehicle 1. The first chassis 21, as the load-bearing member of the entire unit, is fixed on the longitudinal beam at the tail of the Class II chassis vehicle 1, and its strength is improved by welding. A second chassis 22 is arranged above the first chassis 21. Multiple shock absorbers 23 are arranged on the side of the second chassis 22. The second chassis 22 is installed on the top of the first chassis 21 through the shock absorbers 23, preventing excessive vibration generated during vehicle driving from being transmitted to the generator set 4, effectively protecting the structure of the generator set 4, and at the same time facilitating the rapid disassembly of the generator set 4. A silent box 3 is installed on the installation base 2. Sound-absorbing cotton can be arranged on the inner wall of the silent box 3 to prevent the noise generated during power generation inside the silent box 3 from spreading out and affecting the surrounding environment. A fuel tank is suspended and installed on one side beam of the Class II chassis vehicle 1, and the fuel tank is communicated with the gas turbine 41.

[0033] Specifically, the above power supply vehicle includes a generator set 4 installed on the installation base 2, and the generator set 4 is used for power generation. The generator set 4 includes two gas turbines 41. After inhaling air, the gas turbines 41 compress the air to a high-pressure state. After mixing with fuel (such as natural gas or aviation kerosene), the mixture enters the combustion chamber and is ignited. The generated high-temperature gas drives the turbine blades to rotate through the turbine, thereby generating mechanical energy. One end of the two gas turbines 41 is jointly connected to a gearbox 42. The gearbox 42 concentrates the mechanical energy generated by the two gas turbines 41 together, and at the same time increases the rotation speed of the rotating shaft through gear transmission. The side of the gearbox 42 away from the gas turbine 41 is connected to a coupling 43. The gearbox 42 is connected to a high-voltage generator 44 through the coupling 43. The high-voltage generator 44 is used to convert mechanical energy into electrical energy and output the electric quantity through a cable. The gearbox 42, the coupling 43, and the high-voltage generator 44 are all fixedly arranged on the top of the second chassis 22, which is convenient for disassembly and maintenance.

[0034] Furthermore, multiple support components 5 are installed at the bottom of the gas turbine 41. The support components 5 are fixedly connected to the top of the second chassis 22. The support components 5 are used to fix the position of the gas turbine 41 and ensure the stable position of the gas turbine 41 during operation. A fuel and lubricating oil system 6 is also arranged outside the gas turbine 41. The fuel and lubricating oil system 6 is installed on the top of the second chassis 22. The fuel and lubricating oil system 6 is used to reduce the friction and temperature during the operation of the gas turbine 41 and ensure the efficient and stable operation of the gas turbine 41.

[0035] Furthermore, the above power vehicle further includes a ventilation component 7 disposed in the soundproof box 3. The ventilation component 7 is used for ventilation and sound attenuation. The ventilation component 7 includes an intake silencing system 71 and an intake system 72 installed on the top of the soundproof box 3. The intake silencing system 71 is connected to the intake system 72 through an air duct, and the intake system 72 is communicated with the intake duct of the gas turbine 41. External air enters the gas turbine 41 after passing through the intake silencing system 71 and the intake system 72 in sequence, effectively removing the noise generated during the intake process. An exhaust box 73 communicated with the exhaust port of the gas turbine 41 is provided. The gas generated after the gas turbine 41 operates is discharged into the exhaust box 73. An exhaust silencing system 74 is installed on the top wall of the exhaust box 73. The gas in the exhaust box 73 is discharged from the top after passing through the exhaust silencing system 74, and the exhaust silencing system 74 removes the noise generated when the high-speed gas is discharged.

[0036] Finally, the above power vehicle further includes an electrical control system 8 installed on the mounting base 2. The electrical control system 8 is used to control the overall operation of the power vehicle. All the above electrical components are electrically connected to the electrical control system 8 to achieve automatic control. A plurality of skirt plates 9 are installed at the bottom of the first chassis 21. The skirt plates 9 are used for decoration to improve the aesthetic degree of the power vehicle.

[0037] In this embodiment, during operation, the two gas turbines 41 are started synchronously, and external air is inhaled through the intake system 72 and the intake silencing system 71. When the air passes through the intake silencing system 71, the noise generated by the air flow is eliminated. Then the air enters the gas turbine 41. At the same time, the gas turbine 41 extracts fuel from the fuel tank, ignites it, and generates mechanical energy. The mechanical energy is transmitted to the high-voltage generator 44 through the gearbox 42 and the coupling 43 for power generation, and the obtained electric energy is transmitted through the cable. At the same time, the noise generated when the gas turbine 41 operates is isolated inside by the soundproof box 3 to prevent noise pollution. At the same time, the waste gas generated when the gas turbine 41 operates enters the exhaust box 73 and is discharged from the top after being filtered by the exhaust silencing system 74, preventing the noise caused by the high-speed air flow. Therefore, the noise generated by this power vehicle during power generation is small, has little impact on the surrounding environment, and is convenient to use in cities and sensitive areas. At the same time, the detachable manner of the first chassis 21 and the second chassis 22 simplifies the maintenance process, reduces the operation cost, improves the economy of this power vehicle, and is convenient to attract more organizations to adopt.

[0038] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
