Description

Technical Field

[0001] The utility model belongs to the technical field related to gas turbines, and in particular relates to a safe and efficient gas turbine power generation device. Background Art

[0002] A gas turbine is an internal combustion power machine that uses a continuously flowing gas as a working fluid to drive the impeller to rotate at high speed, converting the energy of the fuel into useful work. It is a rotating impeller heat engine. The working process of a gas turbine is that the compressor (i.e., the compressor) continuously inhales air from the atmosphere and compresses it; the compressed air enters the combustion chamber, mixes with the injected fuel and burns to become high-temperature combustion gas, which then flows into the gas turbine to expand and work, driving the turbine impeller to rotate with the compressor impeller; the working capacity of the heated high-temperature combustion gas is significantly improved, so while the gas turbine drives the compressor, there is still surplus work as the output mechanical work of the gas turbine. When the gas turbine is started from a standstill, it needs to be driven by a starter to rotate, and the starter is disconnected after it is accelerated to be able to run independently. When the power generated by the gas turbine is used for power generation, an external power generation device is required to perform power generation operations, but it still has the following disadvantages in actual use:

[0003] When the gas turbine generator is working, it generates electricity by connecting the gas turbine to an external generator. During the operation of the generator, the generator is directly connected with a coupling. When installing, it needs to be aligned, which is troublesome and inconvenient to install.

[0004] When a gas turbine power generation device is in operation, if a generator included in the power generation device fails during operation and needs to be disassembled for maintenance, the generator needs to be moved on the installation table away from the gas turbine before the lifting operation can be performed. During operation, it is inconvenient to disassemble it in a vertical direction using a crane. Utility Model Content

[0005] The purpose of the utility model is to provide a safe and efficient gas turbine power generation device. By arranging a fixing plate, an external fixing plate and a generator, the problems of inconvenience in installing the gas turbine power generation device between the gas turbine when working and inconvenience in directly disassembling the generator by vertical lifting are solved.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a safe and efficient gas turbine power generation device, comprising a fixed disk one, an external fixed disk and a generator, wherein an input shaft is fixed to the output end of the generator, an external fixed disk is fixed to the end of the input shaft away from the generator, a hexagonal socket is provided on the circumferential side of the external fixed disk, a fixed disk two is fixed to the center of an end face of the external fixed disk away from the input shaft, movable plug posts are symmetrically fixed to the end of the fixed disk two away from the external fixed disk, connecting posts are movably connected to the outer sides of the movable plug posts, and a fixed disk one is fixed to the end of the connecting post away from the fixed disk two. When working, the connecting post is connected to it through the fixed disk one, and the movable plug post is connected to it through the external fixed disk. The connecting post and the movable plug post are movably connected to each other, and when the gas turbine main body is working, the external fixed disk is driven to rotate, and the generator is driven to rotate.

[0008] Furthermore, a gas turbine body is arranged on a side of the fixing plate 1 away from the fixing plate 2, two supporting seats 1 are fixed on the circumference of the gas turbine body, and the gas turbine body is supported on the ground by supporting steps 1.

[0009] Furthermore, an output shaft is fixed to the output end of the gas turbine body, and one end of the output shaft away from the gas turbine body is fixed to a fixed disk 1, and the power generated by the gas turbine body is transmitted to the fixed disk 1 through the heat pump and the shaft.

[0010] Furthermore, a clamping groove is radially provided on the peripheral side of the connecting column, and the clamping groove integrally penetrates the connecting column in the horizontal direction, and the connecting column is movably connected to the movable plug-in column through the clamping groove.

[0011] Furthermore, the upper outer side of the generator is fixedly connected with a wiring assembly, and the two movable plug posts are movably connected in the clamping groove, and the generator is powered by the wiring assembly.

[0012] Furthermore, a support base 2 is fixed to the outer side of the generator, and mounting ears are fixed at the four corners of the outer side of the support base 2. The generator is supported on the ground through the support base 2 and is installed on the ground through the mounting ears.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem of inconvenient installation between the gas turbine power generation device and the gas turbine when working by arranging a fixing plate 1, an external fixing plate and a generator. The gas turbine main body is installed on the workbench through a supporting seat 1, and then the installation position of the generator is determined, and the two movable plug posts on the fixing plate 2 are aligned with the clamping grooves on the connecting column. After the movable plug posts are clamped into the clamping grooves, the generator is put down and the installation ears are aligned with the installation structure. When installing on the installation structure, the distance between the generator and the gas turbine main body can be slightly changed without affecting the working effect, so that the installation is more convenient and efficient.

[0015] The utility model solves the problem that it is inconvenient to directly disassemble the generator of the gas turbine power generation device by vertical lifting when the gas turbine power generation device is working by arranging a fixing plate, an external fixing plate and a generator. When the generator needs to be replaced, a hexagonal wrench is inserted into the hexagonal socket on the external fixing plate, and then the external fixing plate is rotated until the clamping groove on the connecting column is aligned with the generator. When the generator needs to be replaced, the output angle is moved, and the generator is vertically lifted by the lifting equipment, and the generator can be moved away, so that the gas turbine power generation device can be directly vertically transported by the crane when it is working, and the operation is more convenient and efficient.
