[0028] Specific embodiments of the present invention will now be described with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of the present invention, which may be implemented in various ways.

[0029] The first embodiment of this utility model provides a gas turbine generator set, such as... Figures 1 to 3 As shown, the gas turbine generator set includes a gas turbine transport unit 100 and a generator transport unit 200. The gas turbine transport unit 100 is used to transport the gas turbine 1, and the generator transport unit 200 is used to transport the generator 2. The gas turbine transport unit 100 is equipped with an intake filtration system 3, an exhaust system 4, and a ventilation system 5. The gas turbine transport unit 100 and the generator transport unit 200 are detachably connected so that they can be docked during fracturing operations or disconnected after fracturing operations are completed. In this way, under normal circumstances, the gas turbine 1, generator 2, intake filtration system 3, exhaust system 4, and ventilation system 5 are transported separately, forming different transport units. During fracturing operations, the intake filtration system 3, exhaust system 4, and ventilation system 5 are assembled with the gas turbine 1, and then the gas turbine transport unit 100 and generator transport unit 200 are docked together. After fracturing is completed, the gas turbine transport unit 100 and generator transport unit 200 are disconnected. This method allows for the docking of the gas turbine transport unit 100 and the generator transport unit 200 without the need for additional connectors, enabling convenient on-site assembly and reducing the footprint at the work site.

[0030] Specifically, the air intake filtration system 3 filters and purifies the air from the outside, the exhaust system 4 is used to exhaust the exhaust gas of the gas turbine 1, and at the same time reduces the flow rate and silences the sound, so as to reduce the noise impact on the surrounding environment, and the ventilation system 5 exchanges the hot air in the cabin with the cooler air outside to keep the silencer cabin at a suitable temperature, so as to ensure that the sensors in the cabin can work normally.

[0031] In some embodiments, the gas turbine transport unit 100 includes a first chassis 6, a gas turbine 1, and a power transmission device 8. The gas turbine 1 is mounted on the first chassis 6 and is detachably connected to the input end of the generator 2 via the power transmission device 8. Alternatively, the generator transport unit 200 includes a second chassis 7, a generator 2, and a power transmission device 8. The generator 2 is mounted on the second chassis 7 and is detachably connected to the input end of the gas turbine 1 via the power transmission device 8. The first chassis 6 and the second chassis 7, as transport vehicles, primarily serve to carry the generator and facilitate rapid transfer and movement of the unit. This design allows for improvements in the arrangement of the gas turbine 1, generator 2, and power transmission device 8. A more efficient arrangement of the space occupied by the first chassis 6 and the second chassis 7 reduces the floor space required at the work site.

[0032] Specifically, the power transmission device 8 includes at least one of a first coupling 801, a gearbox 802, and a second coupling 803. However, to shorten the shaft length of the entire generator set, the power transmission device 8 may include only the first coupling 801, only the gearbox 802, or only the second coupling 803.

[0033] The second coupling 803 is disposed at the end of the first chassis vehicle 6 and is supported on the first chassis vehicle 6 by a bracket 804; or the second coupling 803 is disposed at the end of the second chassis vehicle 7 and is supported on the second chassis vehicle 7 by a bracket 804. The following explanation uses the example of the second coupling 803 being mounted on the first chassis 6. One end of the second coupling 803 is connected to the output end of the gearbox 802, and the other end is connected to the input flange of the generator 2. During transportation, the first chassis 6 and the second chassis 7 are transported separately, and the end of the second coupling 803 connected to the generator 2 needs to be disconnected, resulting in suspension. To ensure the safety of the second coupling 803, a bracket 804 is used to support the second coupling 803 on the first chassis 6 or the second chassis 7. This bracket 804 can maintain the original posture of the second coupling 803 and play a protective role during transportation, preventing the second coupling 803 from deviating from its original position or being damaged due to transportation shaking.

[0034] An air intake structure 101, such as an air intake connector, is provided at the top of one end of the gas turbine 1. The gas turbine 1 is connected to the output end of the air intake filtration system 3 through the air intake connector. The air intake connector is an air intake elbow that bends from the gas turbine 1 toward the air intake filtration system 3. The air intake connector introduces clean air generated after filtration from the air intake filtration system 3 into the gas turbine 1 to ensure that the gas turbine 1 can draw in sufficient air to mix with fuel and generate more heat energy. The air intake elbow not only has the function of changing the direction of airflow, but also has the function of stabilizing the flow. At the same time, since the gas turbine 1 has strict requirements for the uniformity of combustion air in the same rotation section, in order to ensure that the air distribution at the inlet of the gas turbine 1 is uniform, the airflow entering the gas turbine 1 must undergo a certain buffering process and the airflow field must be stabilized before entering the gas turbine 1 to ensure the uniformity of combustion, thereby ensuring the stability and safety of the components of the gas turbine 1.

[0035] The other end of the gas turbine 1 is provided with an exhaust structure 102, for example, the exhaust structure 102 is an exhaust elbow, one end of which is connected to the exhaust port of the gas turbine 1, and the other end is set vertically upward and connected to the exhaust system 4, so as to convert the exhaust gas flow generated by the combustion of the gas turbine 1 from the axial direction to the vertical direction, so as to avoid the airflow affecting the downstream power output.

[0036] The first chassis vehicle 6 and the second chassis vehicle 7 are also equipped with a lubrication system 9, which is mainly responsible for lubricating and cooling various rotating parts on the vehicle to reduce wear, including but not limited to the gas turbine 1, gearbox 802 and other components.

[0037] The gas turbine generator set also includes low-voltage power supply equipment for supplying power to auxiliary equipment. This low-voltage power supply equipment is installed on at least one of the gas turbine transport unit 1 and the generator transport unit 2. The generator transport unit 2 includes medium-voltage power supply equipment for supplying power to power-consuming units. In this embodiment, the medium-voltage power supply equipment is integrated on the generator 2 vehicle, and the low-voltage auxiliary power supply on the gas turbine vehicle directly comes from the generator vehicle or the gas turbine vehicle, improving the reliability and convenience of the gas turbine control system. Here, "power-consuming units" refers to power-consuming equipment, such as fracturing equipment, cementing equipment, data centers, drilling equipment, etc.

[0038] The gas turbine transport unit 100 includes a first chassis 6 and a gas turbine compartment 10 disposed on the first chassis 6. A gas turbine 1 is housed within the gas turbine compartment 10. At least a portion of the air intake filtration system 3, the exhaust system 4, and the ventilation system 5 are located on the top of the gas turbine compartment 10, forming a double-layered arrangement on the first chassis 6, thus making efficient use of the space within the first chassis 6. The air intake filtration system 3 is connected to the air intake of the gas turbine 1, the air outlet of the gas turbine 1 is connected to the exhaust system 4, one end of the ventilation system 5 is connected to the gas turbine compartment 10, and the other end of the ventilation system 5 is connected to the atmosphere.

[0039] Specifically, a control room 11 is provided on the first chassis vehicle 6. The control room 11 is mainly used to house various electrical cabinets, serving as a control room to facilitate internal operation by personnel, while also providing various forms of protection for the electrical cabinets. At least a portion of the air intake filtration system 3 is located on the top of the control room 11. For example, the end of the air intake filtration system 3 is suspended, which can shorten the length of the first chassis vehicle 6 required for application.

[0040] The intake filtration system 3 includes an intake filtration device that filters and blocks larger impurities in the external air, allowing clean air to enter the gas turbine 1 through the airflow channel. Noise is generated during the rapid airflow process. To reduce the impact on the surrounding environment and personnel, an intake silencer is installed to reduce the noise generated by the airflow.

[0041] The ventilation system 5 includes a ventilation filtration device, which is connected to the gas turbine compartment 10 via a fan and a ventilation silencer. The ventilation filtration device and the intake filtration device are arranged sequentially along the height of the first chassis vehicle 6, forming a vertical spatial arrangement that makes efficient use of space.

[0042] The generator transport unit 200 includes a second chassis 7 and an electrical compartment 12 and a generator compartment 13 disposed on the second chassis 7. The generator 2 is disposed in the generator compartment 13, and the medium-voltage power supply equipment is disposed in the electrical compartment. The generator compartment 13 mainly serves to protect the generator 2 body or its external output according to the cooling and protection requirements of the generator 2. The electrical compartment 12 mainly serves to protect the cabinets inside the compartment and ensure the cleanliness of the interior, thereby ensuring the stable operation of the electrical components.
