[0029] Please refer to Figure 1 In one embodiment of the present invention, a method for simulating the disassembly and assembly of equipment is provided. The method is applied to a steam turbine of a thermal power unit. The steam turbine of the thermal power unit includes multiple components. The method includes:

[0030] S10: Obtaining a disassembly and assembly simulation mode of a steam turbine of a thermal power unit selected by a user, wherein the disassembly and assembly simulation mode includes at least one of a disassembly mode and a reassembly mode. The disassembly mode is a mode of disassembling the steam turbine of a thermal power unit into multiple components, and the reassembly mode is a mode of assembling multiple components into a steam turbine of a thermal power unit.

[0031] In some embodiments, a steam turbine of a thermal power unit is a rotating machine that uses steam as power and converts the thermal energy of steam into mechanical work. It is the most widely used prime mover in modern thermal power plants. The steam turbine of a thermal power unit includes components such as a main shaft, an impeller, moving blades, a coupling, a steam inlet part, a cylinder, a partition, a stationary blade grid, a steam seal and a bearing.

[0032] In some embodiments, the steam turbine of the thermal power unit is a 1000MW steam turbine of the thermal power unit.

[0033] S20: Acquire a plurality of pre-built equipment disassembly and assembly animations, each of which is bound to at least one disassembly and assembly step of a preset steam turbine of a thermal power unit.

[0034] In some embodiments, the disassembly and assembly steps are set according to the disassembly and assembly manual of the steam turbine of the thermal power unit. For example, the steam turbine of the thermal power unit includes at least a high-pressure cylinder, and the high-pressure cylinder includes at least a bearing cover hexagonal bolt and a bearing cover. The disassembly and assembly steps are to first remove the bearing cover hexagonal bolt of the high-pressure cylinder, and then remove the bearing cover of the high-pressure cylinder.

[0035] In some embodiments, a method for constructing a device disassembly and assembly animation, such as Figure 2 As shown, including:

[0036] S200: constructing a three-dimensional model of a steam turbine of a thermal power unit, wherein the three-dimensional model includes a plurality of first model nodes, and each first model node corresponds to a disassembly and assembly step.

[0037] In some embodiments, the cylinders in the steam turbine of the thermal power unit include at least a high-pressure cylinder and a low-pressure cylinder, and a pressure cover of the high-pressure cylinder, an upper end cover of the low-pressure cylinder, etc. are all built into three-dimensional models at the component level.

[0038] In some embodiments, Unity (a real-time 3D interactive content creation and operation platform) is used to develop a three-dimensional visualization platform for disassembly and assembly of a steam turbine in a thermal power unit. The three-dimensional visualization platform is a three-dimensional scene constructed based on the operating room on the main plant floor of a thermal power plant. The light source and the camera position for observing the disassembly and assembly process can be set according to actual needs.

[0039] In some embodiments, the steam turbine of the thermal power unit is modeled at a ratio of 1:1, and the modeling tool solidworks can be used to generate an stp model. The modeling depth of the steam turbine of the thermal power unit reaches LOD400, and all parts including bolts must be modeled so that the constructed three-dimensional model has a complete expression; the constructed three-dimensional model is loaded onto a three-dimensional visualization platform developed using Unity, and corresponding interactions for disassembly and assembly simulation are developed, so that each component of the three-dimensional model can be disassembled and assembled according to the designed logic and sequence for simulation interaction.

[0040] S201: After binding each first model node with the corresponding assembly and disassembly step, each device assembly and disassembly animation is obtained.

[0041] In some embodiments, each device disassembly and assembly animation is obtained by binding each first model node with the corresponding disassembly and assembly step based on 3d Max (a 3D modeling, rendering and production software). Other existing 3D modeling, rendering and production software may also be used, which is not limited in this article.

[0042] In some embodiments, the disassembly and assembly step includes a disassembly step and a reassembly step. For the same component, the disassembly step and the reassembly step are different. For example, in the disassembly and assembly step, the main shaft must be lifted out after the upper static blades are removed, and in the reassembly step, the main shaft must be installed after the lower static blades are reassembled.

[0043] In some embodiments, a method for constructing a device disassembly and assembly animation, such as Figure 3 As shown, it also includes:

[0044] S210: Obtain a disassembly and assembly viewing angle corresponding to each disassembly and assembly step, through which the device disassembly and assembly animation corresponding to the disassembly and assembly step can be viewed from different visual angles and / or visual distances.

[0045] In some embodiments, the disassembly and assembly viewing angle can be set according to the disassembly and assembly manual of the thermal power unit steam turbine, and can also be set according to the user's disassembly and assembly experience. Usually, the disassembly and assembly viewing angle is set on the side of the thermal power unit steam turbine as a whole according to the user's habits, and the center of the disassembly and assembly viewing angle is placed on the position of the intermediate pressure cylinder; in some specific cases, for example: when reinstalling the rotor in the high-pressure cylinder of the thermal power unit steam turbine, the disassembly and assembly viewing angle is set above the thermal power unit steam turbine, and the center of the viewing angle is placed on the high-pressure cylinder rotor of the steam turbine.

[0046] S211: Binding each device disassembly and assembly animation to the disassembly and assembly viewing angle, so that the device disassembly and assembly animation can be played at different visual angles and / or visual distances according to the disassembly and assembly viewing angle.

[0049] In some embodiments, the disassembly mode and the reassembly mode differ only in the order in which the multiple device disassembly and assembly animations are played, for example, the order in which the multiple device disassembly and assembly animations are played in the reassembly mode is the reverse order of the order in which the multiple device disassembly and assembly animations are played in the disassembly mode.

[0056] S33: When the disassembly mode is manual disassembly, the device disassembly animation is played according to the user instruction, and the user instruction at least includes a selection instruction of the second model node, and the second model node is a model node actually selected by the user based on the three-dimensional model.

[0057] In some embodiments, when the disassembly mode is manual disassembly, the user manually selects the three-dimensional model of the steam turbine of the thermal power unit to start playing the equipment disassembly animation. If the name of the second model node selected by the user based on the three-dimensional model completely matches the name of the first model node bound to one of the disassembly steps, the equipment disassembly animation corresponding to the disassembly step will be played.
