Description

Technical Field

[0001] The present invention relates to the technical field of rotor hoisting, and in particular to a rotor hoisting monitoring system for a hydro-turbine generator set. Background Art

[0002] The rotor of a large hydro-turbine generator set is large in size and heavy in weight, and the small gap between the rotor and the stator makes it difficult to hoist the rotor. When hoisting the rotor, two bridge cranes or a single bridge crane with two trolleys are required for joint hoisting, and a special balance beam hoist is used for hoisting. During the hoisting process, there may be a problem of asynchrony between the two bridge cranes or the lifting mechanisms of the two trolleys, causing the level of the balance beam and the rotor to change. The level control on site is mostly based on the experience and skill level of the hoisting commander.

[0034] It can be understood that the control module 1 uses the first monitoring module 2 to collect the first horizontal data of the balance beam, and uses the second monitoring module 3 to collect the second horizontal data of the top of the rotor and the third horizontal data of the bottom of the rotor, and uses the third monitoring module 4 to collect the impact data between the rotor and the stator, and then controls the lifting equipment according to the first horizontal data, the second horizontal data, the third horizontal data and the impact data, so that when the balance beam and the rotor change horizontally, the problem can be discovered in time, and the rotor posture can be automatically corrected, thereby achieving precise alignment of the rotor and the stator, avoiding friction between the rotor and the stator, and ensuring the safe and stable operation of the hydro-turbine generator set.

[0035] It should be noted that the lifting equipment is used to lift the rotor using a balance beam. The specific type of the lifting equipment can be set according to actual needs and is not limited to this. For example, the lifting equipment can be two bridge cranes or a single bridge crane, wherein the single bridge crane uses a double trolley for combined lifting.

[0074] like Figure 4As shown, in some embodiments, the third monitoring module 4 includes: multiple fourth sub-modules, the fourth sub-modules include: a fourth magnetic component 41, a pressure sensor 42, a fourth wireless substation 43 and a fourth battery 44, the pressure sensor 42 is arranged on the fourth magnetic component 41, and the output end of the pressure sensor 42 is connected to the input end of the fourth wireless substation 43, the output end of the fourth wireless substation 43 is wirelessly connected to the input end of the control module 1, and the power supply end of the fourth battery 44 is respectively connected to the power supply end of the pressure sensor 42 and the power supply end of the fourth wireless substation 43; wherein, the fourth magnetic components 41 of the multiple fourth sub-modules are respectively arranged on the side walls of the rotor along the circumference of the rotor, and the multiple pressure sensors 42 are used to detect the pressure at multiple positions between the rotor side wall and the stator side wall, the control module 1 is used to obtain the fourth horizontal deviation value of the rotor according to the multiple pressures, and obtain the fourth adjustment amount of the rotor according to the fourth horizontal deviation value, and control the lifting equipment according to the fourth adjustment amount so that the rotor is installed in the stator in a centered manner.

[0075] It can be understood that since the fourth magnetic attraction component 41 is arranged on the side wall of the rotor and the pressure sensor 42 is arranged on the fourth magnetic attraction component 41, the pressure sensors 42 of multiple fourth sub-modules can detect the pressure at multiple positions between the rotor side wall and the stator side wall, so that the control module 1 can obtain the fourth horizontal deviation value of the rotor according to the multiple pressures, and obtain the fourth adjustment amount of the rotor according to the fourth horizontal deviation value, and then control the lifting equipment according to the fourth adjustment amount to ensure the precise installation of the rotor in the stator.

[0076] The pressure sensor 42 is arranged on the side wall of the rotor by using the fourth magnetic attraction component 41, which can not only ensure the stable measurement of the pressure but also facilitate the disassembly and assembly, making the use of the third monitoring module 4 more convenient.

[0077] Since the output end of the pressure sensor 42 is connected to the input end of the fourth wireless substation 43, and the output end of the fourth wireless substation 43 is wirelessly connected to the input end of the control module 1, the pressure sensor 42 can use the fourth wireless substation 43 to communicate wirelessly with the control module 1, so that the use of the pressure sensor 42 is not restricted by the communication line, thereby making the use of the third monitoring module 4 more convenient.

[0078] Since the power supply end of the fourth battery 44 is respectively connected to the power supply end of the pressure sensor 42 and the power supply end of the fourth wireless substation 43, the fourth battery 44 can supply power to the pressure sensor 42 and the fourth wireless substation 43, thereby ensuring the stable operation of the pressure sensor 42. At the same time, the use of the pressure sensor 42 is not restricted by the power supply line, thereby making the use of the third monitoring module 4 more convenient.

[0079] It should be noted that the third monitoring module 4 is divided into a plurality of fourth sub-modules, so that the installation, use, disassembly and storage of the third monitoring module 4 are more convenient, wherein the number of fourth sub-modules can be set according to actual needs and is not limited thereto.

[0087] At the same time, since the multiple first magnetic poles and the multiple second magnetic poles are distributed at intervals along the circumference of the rotor, and the multiple fourth magnetic suction components 41 are respectively arranged on the side walls of the multiple first magnetic poles, the multiple anti-collision edge strips 45 can be distributed more densely and evenly on the side walls of the rotor, thereby achieving stable anti-collision between the rotor and the stator, while avoiding the reduction of lifting efficiency and increase of cost due to the setting of too many anti-collision edge strips 45.

[0088] Since the pressure sensor 42 is arranged in the anti-collision edge strip 45, the rotor uses the anti-collision edge strip 45 to prevent collision while also arranging and protecting the pressure sensor 42, thereby ensuring stable pressure detection of the pressure sensor 42.

[0089] It should be noted that the first magnetic pole and the second magnetic pole are both magnetic poles of the rotor, and the plurality of fourth magnetic attraction components 41 are respectively arranged on the side walls of the plurality of first magnetic poles, that is, in the circumferential direction of the rotor, an anti-collision edge strip 45 is arranged at every other magnetic pole.
