DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is formed "on" or "under" another element, it can not only be directly formed "on" or "under" another element, but also be indirectly formed "on" or "under" another element through an intermediate element.

[0022] Figure 1 A schematic diagram schematically shows the structure of a gas turbine generator set according to an embodiment of the present invention, Figure 2 A schematic diagram showing a first-view structure of a power generation system compartment according to an embodiment of the present invention, Figure 3 A schematic diagram showing a second perspective view of a power generation platform chamber according to an embodiment of the present invention, Figure 4 The internal equipment distribution diagram of the electrical system warehouse of one embodiment of the present invention is schematically shown as follows: Figure 1-4 As shown, a gas turbine generator set of the present invention comprises: The power generation system compartment 10 and the electrical system compartment 20 are connected by pipelines; The power generation system compartment 10 includes a power generation platform compartment 101, a fan compartment 102 and a control compartment 103, and the power generation platform compartment 101, the fan compartment 102 and the control compartment 103 are separated and arranged; The power generation platform chamber 101 is provided with a power generation device 1011 and a pipeline system 1012. The power generation device 1011 and the pipeline system 1012 are separated by a first support platform 1013. The first support platform 1013 supports the power generation device 1011. The pipeline system 1012 is respectively connected to the power generation device 1011, the electrical system chamber 20 and the fan chamber 102. The fan chamber 102 is used to provide cooling air, and the power generation device 1011 is used to generate electricity. The electrical system compartment 20 includes an electrical equipment compartment 201 and a chiller compartment 202. The electrical equipment compartment 201 and the chiller compartment 202 are separated and connected to the pipeline system 1012 respectively. The chiller compartment 202 is used to provide cooling liquid, and the electrical equipment compartment 201 is used to receive electricity generated by the power generation equipment 1011 and transmit it to the outside. A ventilation structure 30 is provided on the power generation system compartment 10 and the electrical system compartment 20 , and the ventilation structure 30 is used for air flow to dissipate heat from the equipment in the power generation system compartment 10 and the electrical system compartment 20 .

[0023] Specifically, the power generation system compartment 10 is used for power generation, and the electrical system compartment 20 is used for receiving the electricity generated by the power generation system compartment 10 and transmitting it to the outside. The two are connected by pipelines to achieve circulation. By setting up the equipment for power generation and the equipment for power transmission in separate compartments, the problems of crowded equipment layout and messy pipelines when the two are in a single compartment are avoided. The separate compartments make the interior more concise as a whole, making it convenient for personnel to enter the compartment for inspection and maintenance.

[0024] At the same time, the compartment setting can also achieve functional decoupling of the gas turbine generator set. Different numbers of power generation system compartments 10 and different numbers of electrical system compartments 20 can be flexibly combined to achieve different power generation and transformation power effects, thereby realizing the effective expansion of the power generation power of the gas turbine generator set.

[0025] A first supporting platform 1013 is provided in the power generation platform chamber 101. The first supporting platform 1013 separates the power generation equipment 1011 from the pipeline system 1012 so that the complex pipelines and equipment are not stacked together. At the same time, when maintenance personnel inspect the power generation equipment 1011, they can also be supported by the first supporting platform 1013 to provide a standing fulcrum.

[0026] Furthermore, if Figure 2 As shown, the power generation equipment 1011 includes a gas turbine 10111 and a generator 10112. The gas turbine 10111 and the generator 10112 are transmission-connected. The gas turbine 10111 is used to receive fuel and generate power, and the generator 10112 is used to generate power.

[0027] The pipeline system 1012 includes a fuel pipeline 10121, a lubricating oil pipeline 10122, a cooling water pipeline 10123 and a cooling air pipeline 10124; The fuel pipeline 10121 and the lubricating oil pipeline 10122 are connected to the gas turbine 10111, the fuel pipeline 10121 is used to provide fuel, and the lubricating oil pipeline 10122 is used to perform oil cooling on the gas turbine 10111; The cooling air pipeline 10124 and the cooling water pipeline 10123 are connected to the generator 10112 . The cooling air pipeline 10124 is used to perform air cooling on the generator 10112 , and the cooling water pipeline 10123 is used to perform water cooling on the generator 10112 .

[0028] Specifically, Figure 2 As shown, the fan chamber 102 includes a fan 1021 and a second support platform 1022. The fuel pipeline 10121 is connected to the outside through the fan chamber 102. The second support platform 1022 is used to separate the fan 1021 from the fuel pipeline 10121 to avoid the fuel pipeline 10121 and the fan 1021 being arranged in a disorderly manner. The cooling air pipeline 10124 is connected to the outside of the power generation system compartment 10 via the fan 1021, and the fan 1021 is used to deliver cooling air to the generator 10112.

[0029] An oil tank 10125 and a heat exchanger 10126 are provided in the pipeline system 1012 at the bottom of the first supporting platform 1013. The lubricating oil pipeline 10122 is a circulating pipeline, one end of which is led out through the oil tank 10125, passes through the heat exchanger 10126, and is connected to the gas turbine 10111, and the other end is led out through the gas turbine 10111 and connected to the oil tank 10125. When the lubricating oil pipeline 10122 is connected to the gas turbine 10111, it is specifically connected to the rotor of the gas turbine 10111 to provide lubricating oil for the rotor bearing of the gas turbine 10111. The rotor bearing is cooled by the lubricating oil, and the heat energy is taken away. Then, the lubricating oil returns to the oil tank 10125. When it flows out again, it first enters the heat exchanger 10126 for cooling, and then enters the gas turbine 10111 to complete the heat exchange, and then returns to the oil tank 10125, thereby realizing the cooling and self-circulation of the gas turbine 10111.

[0030] Similarly, the cooling air duct 10124 is also a circulation duct, one end of which is connected to the outside of the power generation system compartment 10 and connected to the generator 10112 via the fan 1021, and the other end is led out through the generator 10112 and connected to the outside of the power generation system compartment 10; When the cooling air duct 10124 is connected to the generator 10112, specifically to the rotor inside the generator 10112, when the fan 1021 draws air, the cooling air with low external temperature enters the generator 10112 through the cooling air duct 10124 for cooling. The cooling air after heat exchange is discharged from the power generation system compartment 10 through the cooling air duct 10124, completing the cycle and achieving cooling of the generator 10112.

[0031] Furthermore, if Figure 4As shown, a transformer 2011 is arranged in the electrical equipment compartment 201, one end of the transformer 2011 is connected to the pipeline of the power generation equipment 1011, and the other end is connected to the external power supply line; The chiller chamber 202 is connected to the generator 10112 via a cooling water pipeline 10123 .

[0032] Specifically, a chiller 2021 is installed in the chiller compartment 202, and the cooling water pipeline 10123 is also a circulation pipeline, one end of which extends out of the power generation system compartment 10 and enters the electrical system compartment 20 and is connected to the chiller 2021, and the other end is led out from the chiller 2021 and returned to the power generation system compartment 10, and is respectively connected to the heat exchanger 10126 and the generator 10112.

[0033] When one of the cooling water pipes 10123 is connected to the generator 10112, specifically to the outer casing of the generator 10112, the stator in the outer casing is water-cooled, and the cooling water after heat exchange returns to the chiller 2021 and is re-cooled by the chiller 2021 to complete the cycle.

[0034] When another cooling water pipeline 10123 is connected to the heat exchanger 10126, it also completes heat exchange therein and then returns to the chiller 2021 for re-cooling to complete the cycle.

[0035] The transformer 2011 is connected to the generator 1011, and is capable of receiving electricity generated by the generator 10112 and transmitting the electricity to the outside at a specified current and voltage.

[0036] Furthermore, the oil tank 10125 is also connected to a refueling pipe (not shown in the figure), which passes through the fan chamber 102 and specifically passes through the bottom of the second supporting platform 1022 to communicate with the outside of the power generation system chamber 10 to replenish the lubricating oil.

[0037] Furthermore, if Figure 3 As shown, the control chamber 103 includes a control box 1031 , and the control box 1031 is connected to the power generation equipment 1011 via cables to achieve control and monitoring of the power generation equipment 1011 .

[0038] Further, Figure 5 A schematic diagram schematically shows the structure of a first shell according to an embodiment of the present invention, Figure 6 A schematic diagram schematically shows the structure of a rain cover according to a first embodiment of the present invention. Figure 7 A schematic diagram schematically shows the structure of a rain cover according to a second embodiment of the present invention. Figure 8 A schematic diagram schematically shows the structure of the second shell of an embodiment of the present invention, as shown in FIG. Figure 5-8 As shown: The power generation system compartment 10 further includes a first shell 104, and the electrical system compartment 20 further includes a second shell 203. The power generation platform compartment 101, the fan compartment 102 and the control compartment 103 are located in the first shell 104, and the electrical equipment compartment 201 and the chiller compartment 202 are located in the second shell 203; The ventilation structure 30 includes a plurality of first ventilation holes 301, a rain cover 302 and a shutter 303. The first ventilation holes 301 and the rain cover 302 are arranged on the top and side of the first shell 104, and the shutter 303 is arranged on the side of the second shell 203; The rain cover 302 is located outside the first ventilation hole 301, and the rain cover 302 is detachably connected to the first shell 104, and the rain cover 302 covers the plurality of first ventilation holes 301; A vent 3021 is provided on the rain cover 302 , and the vent 3021 is used for air to flow through the first ventilation hole 301 and enter the first shell 104 .

[0039] Specifically, a first ventilation hole 301 is provided on the first shell 104, which is used for air flow in the power generation system compartment 10 to cool down the internal equipment, and a rain cover 302 is provided on the outside of the first ventilation hole 301 to prevent rain or dust from entering the first shell 104 through the first ventilation hole 301 and affecting the internal equipment.

[0040] like Figure 6 As shown, when the rain cover 302 covers the first ventilation holes 301 on the top of the first shell 104, the overall area of ​​the rain cover 302 is larger than the area surrounded by the plurality of first ventilation holes 301, and at the same time, the bottom of the rain cover 302 is connected to the first shell 104, so that the rain cover 302 can completely cover the first ventilation holes 301 to prevent rain or dust from entering the first shell 104; At the same time, in order to ensure ventilation, a vent 3021 is set at the bottom of the rain cover 302 and on the part beyond the first ventilation hole 301. The vent 3021 connects the outside of the rain cover 302 with the internal space. In this way, when the rain cover 302 covers the first ventilation hole 301, ventilation inside the first shell 104 can still be achieved through the vent 3021.

[0041] like Figure 7 As shown, when the rain cover 302 covers the first ventilation hole 301 on the side of the first shell 104, the top and both sides of the rain cover 302 are connected to the first shell 104, so that the top and both sides of the first ventilation hole 301 are completely sealed, preventing dust or rainwater from entering the first shell 104 through the first ventilation hole 301; A vent 3021 is provided at the bottom of the rain cover 302, and air flow in the first shell 104 is achieved through the vent 3021. At the same time, the vent 3021 is provided at the bottom. When dust or rainwater passes through the rain cover 302, it will directly slide down from the side and will no longer move up through the vent 3021 and enter the first shell 104 through the first ventilation hole 301, thereby achieving dust and rain protection.

[0042] And as Figure 8 As shown, a shutter 303 is provided on the side of the second shell 203 , and the opening on the shutter 303 can also achieve rain and dust protection without affecting air circulation, thereby effectively achieving air flow inside the second shell 203 .

[0043] In addition, a sliding door (not shown in the figure) is provided on the side wall of the second shell 203 , and the shutter 303 is provided on the sliding door, so that personnel can enter the second shell 203 for inspection and examination by opening the sliding door.

[0044] Furthermore, a flip door 1041 is provided on the side wall of the first shell 104 facing the power generation equipment 1011, and the top of the flip door 1041 is rotatably connected to the first shell 104. The flip door 1041 is used to open the power generation platform chamber 101 for maintenance personnel to enter for inspection and maintenance; A human-machine interface 1042 is provided on the side wall of the first shell 104 around the flip door 1041. The human-machine interface 1042 is connected to the control box 1031 by pipeline. The human-machine interface 1042 can display the operation status of the internal power generation equipment 1011 and can control the flip door 1041 to flip and open and close.

[0045] A swing door 1043 is provided on a side wall of the first shell 104 opposite to the flip door 1041 . The swing door 1043 is used to open the control compartment 103 , so that maintenance personnel can enter the control compartment 103 .

[0046] Further, Fig. 9 A schematic diagram of the structure of a chassis according to an embodiment of the present invention is shown as follows: Fig. 9 As shown: A chassis 40 is provided at the bottom of the first shell 104 and the second shell 203, respectively. The chassis 40 is provided with a drainage hole 401 and a pipeline channel 402. The pipelines connecting the power generation system compartment 10 and the electrical system compartment 20 pass through the pipeline channel 402. This can avoid that pipelines of various devices are extended from the first shell 104 at different positions to be connected with the electrical system compartment 20. The pipelines are constrained and passed through the pipeline channel 402, which can further avoid pipeline clutter.

[0047] The chassis 40 is welded by a plurality of profiles and plates, and legs are provided at the four corners of the bottom to support the ground, so that the first shell 104 and the second shell 203 are raised as a whole to avoid being soaked in water, and shock absorption can also be achieved. A panel is connected between each two legs, and the bottom space of the chassis 40 can be sealed by the panel setting; The drainage holes 401 on the chassis 40 can drain the accumulated water at the bottom of the power generation system compartment 10 to prevent the equipment from being soaked in water.

[0048] A crossbeam is provided at the bottom of the chassis 40, and the first supporting platform 1013 is supported on the crossbeam through pillars, and the first supporting platform 1013 supports the power generation equipment 1011. When the power generation equipment 1011 is running, the fixed connection between the pillar and the crossbeam has better shock absorption than the planar fixed connection between the pillar and the chassis 40.

[0049] In addition, cylinders (not shown in the figure) for assisting lifting are provided on both sides of the chassis 40. The cylinders are movably connected to the chassis 40, so that the chassis 40 can be pulled out when in use and pushed in to be stored when not in use.

[0050] Furthermore, the power generation platform chamber 101, the fan chamber 102 and the control chamber 103 are separated by a first partition (not shown in the figure). The first partition and the first shell 104 are made of heat-insulating and noise-reducing materials, which can effectively reduce the pollution of the internal equipment to the surrounding environment.

[0051] In summary, through the arrangement of the present invention, by arranging equipment with different functions in different compartments and arranging equipment and pipelines in different zones, it is possible to effectively avoid crowded arrangement between multiple equipment and messy distribution of pipelines, and to reasonably utilize the compartment space, which is convenient for use and maintenance by personnel; At the same time, the compartment setting can also achieve functional decoupling of the gas turbine generator set. Different numbers of power generation system compartments 10 and different numbers of electrical system compartments 20 can be flexibly combined to achieve different power generation and transformation power effects, thereby realizing effective expansion of the power generation power of the gas turbine generator set.
