Detailed description of the invention
As shown in Fig. 1 ~ Fig. 4, a kind of Large Hydroelectric Set rotor lifting detecting device, comprises terrain module, commander's control module.Described terrain module comprises stuck-module, sound and light alarm module 3, wireless signal transmitting module 4, trigger module 2; Described sound and light alarm module 3, wireless signal transmitting module 4, trigger module 2 are arranged on stuck-module.Described commander's control module comprises reception of wireless signals module, display module, and reception of wireless signals module connects display module.Between described wireless signal transmitting module 4 and reception of wireless signals module, be connected by Mesh network service.Described stuck-module comprises flat board 41, riser 1, dull and stereotyped 41 are placed on Stator insulation booth by fixing notch 42, riser 1 leans against Stator iron core surface, wireless signal transmitting module 4, sound and light alarm module 3 are installed on riser 1, and wireless signal transmitting module 4, sound and light alarm module 3 are connected with trigger module 2 respectively.Described sound and light alarm module 3 comprises yellow warning light 311, early warning buzzer phone 312, red alarm lamp 321, alarm buzzer 322.Described trigger module 2 comprises rigidity hemisphere 21,21 connection plugs 22 of rigidity hemisphere, on described riser 1, offer jack 24, between described rigidity hemisphere 21 and riser 1, be provided with holddown spring 23, jack 24 tops, below arrange respectively semi-ring 25, lower semi-ring 26, and upper semi-ring 25, lower semi-ring 26 connect respectively sound and light alarm module 3.On described riser 1, offer circular hole 11, wiring groove 12, rigidity hemisphere 21 is positioned at circular hole 11.
Implementation step:
The terrain module of the utility model device is 12 covers, evenly branch is in electrical generator unit stator core surface, out frame around four quadrants has respectively a Si Suo coordination personnel inspection, separately has lifting commander in chief personnel at command set, control bridge machine driver operation.When every arbitrage ground module is used, the fixing notch 42 of stuck-module is placed on generator stator insulator box.Riser 1 leans against Stator iron core surface.In the time that rotor hangs out or hangs in generator unit stator machine hole, there is inevitably slight swing, rotor and stator gap change thereupon.When rotor core is during near stator core, touch the rigidity hemisphere 21 of trigger module 2, rigidity hemisphere 21 can be pressed into, and holddown spring 23 is compacted, drives conductor plug 22 to insert jack 24.When plug 22 inserts the interior 5mm of jack 24 place, can will contact upper semi-ring 25 and contact down semi-ring 26 conductings, thereby connect the early warning part 31 in sound and light alarm module 3, now yellow warning light flicker, early warning buzzer phone ring.In the time that conduction plug 22 inserts the interior 15mm of jack 24 place, can will contact upper semi-ring 25 and contact down semi-ring 26 conductings, thereby connect the warning part 32 in sound and light alarm module 3, now red alarm flicker, alarm buzzer ring.When sound and light alarm module 3 is reported to the police, the flicker of terrain module alarm lamp ring, by wireless signal transmitting module 4, pre-, alerting signal are sent, reception of wireless signals module receives early warning, alerting signal simultaneously, shows the spatial variations amount of rotor particular location by display module.Lifting commander in chief can find in the very first time spatial variations situation of rotor particular location, control bridge machine driver shut-down operation in time, the rope coordination personnel of commander department terrain acknowledgment signal position and the concrete spatiality of rotor, after confirmation, then control bridge machine driver carries out corresponding operating.Now, in whole process, hoisting commanding is active state all the time.
