Abstract

A bulb tubular water turbine generator set runner connecting bolt fracture warning device is characterized in that two to three connecting bolt fracture warning devices provided by the invention are installed on a runner main shaft seal base plate opposite to a connecting bolt reference circle, a fracture tube in the warning device penetrates through the runner main shaft seal base plate and is supported by a support tube and a connecting seat of the fracture tube, inner threads are arranged in the support tube and the connecting seat, external threads are arranged at two ends of the fracture tube, a ring groove is arranged at one end of the fracture tube, the end of the fracture tube extends out of the support tube, and the other end of the fracture tube is connected with a control valve and a signal generator. The bulb tubular water turbine generator set runner connecting bolt fracture warning device can send a signal rapidly when a bolt fractures, so that monitoring staff can adopt response measures timely, and an accident is prevented from expanding.

Description

Bulb tubular hydraulic generating set runner coupling bolt breaking alarm device
Technical field
The invention belongs to the bulb tubular hydraulic generating set runner coupling bolt breaking alarm device be applied on hydroelectric power plant's rotary wheel of water turbine.
Background technology
In China, bulb tubular hydraulic generating set gets more and more, because rotary wheel of water turbine and main shaft coupling bolt are subject to the resultant strain power effect of powerful stretching, compression, shearing, twisting resistance simultaneously, easily there is fracture accident, in free state after bolt fracture, the equipment such as maintenance sealing, main shaft seal, interior water guide cone in extruding small space is caused seal break-off by bolt and nut, seal member will occur to leak in a large number after damaging, draining will cause water logging workshop accident not in time, causes larger economic loss.
Guangxi Bai Longtan Installation in Plant 6 bulb tubular hydraulic generating sets, rated speed is 93.8r/min, No. 4 units, in March, 2006 and in October, 2010, bolt fracture leakage accident occur respectively, all can not Timeliness coverage, causes economic loss.Can not Timeliness coverage problem for bolt fracture; applicant studies and has invented a kind of bulb through-flow turbine runner coupling bolt breaking alarm device; after this warning device is installed; signal alarm can be sent in time during bolt fracture; monitoring personnel receives the report for police service after signal and takes the emergency measures such as shutdown in time, avoids break bolt percussion, a large amount of leakage accidents that extrusion damage seal member causes occur.
Summary of the invention
The technical problem to be solved in the present invention is that after bolt fracture, energy and alarm are shut down, and avoids the bulb tubular hydraulic generating set runner coupling bolt breaking alarm device causing unit to leak in a large number because of bad seals.
The present invention solves the problems of the technologies described above with following technical scheme:
Bulb tubular hydraulic generating set runner coupling bolt breaking alarm device of the present invention, on the runner main shaft seal foundation plate relative with coupling bolt calibration garden, is provided with 2 to 3 coupling bolt breaking alarm devices of the present invention; Disrumpent feelings pipe in warning device is through runner main shaft seal foundation plate, supported by the stay pipe of disrumpent feelings pipe and the Connection Block of disrumpent feelings pipe, stay pipe and Connection Block have internal thread, all there is external thread at the two ends of disrumpent feelings pipe, one end that disrumpent feelings pipe stretches out stay pipe is cecum, tube-surface close to end has annular groove, and the other end is connected with by-pass valve control 7 and signal generator 8.
Stay pipe 4 and the Connection Block 6 of runner main shaft seal foundation plate 5 and both sides are welded and fixed.
Use bulb tubular hydraulic generating set runner coupling bolt breaking alarm device of the present invention, when bolt fracture, signal can be sent fast, thus make monitoring personnel take counter-measure in time, avoid fault spread, this device has been applied to Guangxi Bai Longtan power plant 6 units.
Accompanying drawing explanation
Fig. 1 is bulb tubular hydraulic generating set runner coupling bolt breaking alarm device structural representation of the present invention.
In figure; 1-rotating part 2-coupling bolt 3-disrumpent feelings pipe 4-stay pipe 5-runner main shaft seal foundation plate 6-Connection Block 7-by-pass valve control 8-signal generator 9-monitor
Embodiment
Bulb tubular hydraulic generating set runner coupling bolt breaking alarm device of the present invention, position relative with coupling bolt calibration garden on runner main shaft seal foundation plate, is provided with 2 to 3 runner of hydro-generating unit coupling bolt breaking alarm devices of the present invention; The disrumpent feelings pipe 3 of warning device passes perpendicularly through runner main shaft seal foundation plate 5, disrumpent feelings pipe 3 supports by the stay pipe 4 submerged in water with at the Connection Block 6 at generator scene, stay pipe 4 and the Connection Block 6 of runner main shaft seal foundation plate 5 and both sides are welded and fixed, and stay pipe 4 and Connection Block 6 all have internal thread; The two-end part of disrumpent feelings pipe 3 all has one section of external thread matched with the internal thread of stay pipe 4 and Connection Block 6: one end that disrumpent feelings pipe 3 stretches out stay pipe 4 is cecum, tube-surface close to end has 1-2 bar annular groove, and the one end stretching into generator scene is connected with by-pass valve control 7 and signal generator 8.
Before normal production, mix up the gap between disrumpent feelings pipe 3 end face and runner of hydro-generating unit coupling bolt 2, gap width is within the scope of 10mm, and hydrogenerator can enter normal production.
In production run, any one is had to damage fracture in coupling bolt, under the effect of the rotation and vibration of unit, if the bolt head of fracture is longer, screw can be deviate from, after deviating from the gap 10mm that distance is greater than between disrumpent feelings pipe 3 end face and runner of hydro-generating unit coupling bolt 2, the disconnected disrumpent feelings pipe 3 with weak groove will be touched; If the bolt head of fracture is shorter, bolt head can be thrown out of and fly in narrow space civil strike, the disrumpent feelings pipe 3 in the same space will be hit, annular groove due to disrumpent feelings pipe end makes the groove intensity step-down of disrumpent feelings pipe, the very fast brisement of disrumpent feelings pipe, it is on-the-spot that namely outside water flow into generator through disrumpent feelings pipe.If fail Timeliness coverage, the factory building at generator scene will certainly be caused to be soaked, by forced-stopping machine.If but employed bulb tubular hydraulic generating set runner coupling bolt breaking alarm device of the present invention, being located at monitor 9 in Control Room could Timeliness coverage, shuts down process in time, avoids factory building and soaked.
