Description
Technical field
This utility model relates to hydroelectric power plant's turbine state monitoring technical field, and specifically a kind of hydroelectric power plant guide vanes of water turbine is obstructed monitoring device.
Background technology
Hydraulic power plant is called for short hydroelectric power plant, it is the factory potential energy of water and kinetic energy being converted into electric energy, its basic process of production is: diversion in river eminence or other reservoirs, the pressure or the flow velocity pelton wheel that utilize water rotate, gravitional force and kinetic energy are transformed into mechanical energy, then the hydraulic turbine drives electromotor to rotate, and mechanical energy is become electric energy.Break pin signal indicator is made up of break pin and signal indicator thereof, in guide blade transmitting mechanism for water turbine, connecting plate is connected by break pin with guide vane lever, under normal circumstances, stator break pin in course of action is driven stator to rotate by sufficient intensity, when having foreign body to block when between stator, stator rotates and is obstructed, guide vane teunnion and guide vane lever are the most active, and connecting plate rotates under jaw drives, therefore break pin is produced shearing, when this shearing is more than 1.5 times of normal operating stress, break pin is cut off, this stator departs from and controls, but other stator still can normal rotation, it is to avoid fault spread.
The connected mode that existing hydroelectric power plant break pin monitoring stator is obstructed uses mode in parallel, when there is broken string in break pin loop in parallel, the corresponding break pin information of cutting off can not report host computer, if occurring in that, failing to report phenomenon now occurs that the stator of the hydraulic turbine is obstructed phenomenon, and break pin signal indicator can not will cut off information reporting to host computer；If things go on like this cause stator to wear and tear, the situation that stator is not closed completely occurs, be unfavorable for the safe operation of hydroelectric power plant.
Programmable Logic Controller (Programmable Logic
Controller) being called for short PLC, have programming simple, functional strong advantage, time in hydroelectric power plant's information monitoring, reliability is high, and capacity of resisting disturbance is strong, it is possible to monitor many index simultaneously, and wiring is simple, easy to maintenance.
Summary of the invention
In order to solve the defect that above-mentioned prior art exists, this utility model provides a kind of hydroelectric power plant guide vanes of water turbine and is obstructed monitoring device, it is possible to will cut off information reporting to host computer in time.
The technical solution adopted in the utility model: a kind of hydroelectric power plant guide vanes of water turbine is obstructed monitoring device, this monitoring device includes the power module for power supply, for monitoring break pin signal indicator that stator is obstructed, for monitoring the relay of break pin signal indicator state；The both positive and negative polarity of the both positive and negative polarity contact relay of described power module, the relay coil multiple break pin signal indicatoies of series connection, relay normally open contact K2 connects the input of Programmable Logic Controller through terminal block, the outfan of Programmable Logic Controller connects fiber optical transceiver, and fiber optical transceiver connects host computer by switch.
Preferably, described monitoring device also includes cutting off signal lamp, and the normally closed contact K1 of relay connects and cuts off signal lamp.
Preferably, described Programmable Logic Controller uses SIEMENS S 7-200 PLC.
Preferably, described break pin signal indicator uses ZJX-3A type break pin signal indicator.
Preferably, described power module uses SP-150-24 power supply changeover device.
The beneficial effects of the utility model: by finding in the actual motion of hydroelectric power plant, the stator using this utility model to provide is obstructed after monitoring device, the mode using series connection connects all of break pin signal indicator, water turbine shear pin signal indicator can report the information of cutting off in time, effectively eliminate and fail to report phenomenon, thus alleviate the abrasion of guide vanes of water turbine, reduce the cost of overhaul use of hydroelectric power plant, improve the economic benefit of hydroelectric power plant.This utility model uses host computer monitoring and on-the-spot display lamp monitoring two ways, improves the work efficiency of hydroelectric power plant.
Accompanying drawing explanation
Fig. 1 is structure principle chart of the present utility model；
Fig. 2 is fundamental diagram of the present utility model；
In figure, 1, break pin signal indicator.
Detailed description of the invention
The following is a specific embodiment of the present utility model, be described further in conjunction with accompanying drawing.
As shown in Figure 1, first the power supply terminal row from hydroelectric power plant draws the power supply of a road alternating current 220V, and with circuit tester measure whether be alternating current 220V, alternating current 220V connects a power conversion module and fixes, survey whether its outlet is DC24V, the coil of relay is connected serially in DC24V loop with the break pin signal indicator 1 connected.Second step draws relay normally open k2 contact from relay, and k2 opens into module through what terminal block met PLC, and the module of outputing of PLC connects fiber optical transceiver, and fiber optical transceiver connects switch by optical fiber cable, and switch connects host computer by netting twine.The normally closed k1 contact of the 3rd step relay connects break pin signal indicator 1 display lamp.It should be noted that safe precaution measure in aforesaid operations, wiring process should disconnect alternating current 220V power supply.After aforesaid operations, should test, specific practice is as follows: artificial disconnection break pin signal indicator 1, checks whether host computer reports break pin signal indicator 1 to cut off, and next checks whether break pin signal indicator 1 display lamp is lighted.
Break pin signal indicator 1 being arranged on request on the mechanical arm of stator, its equivalent circuit operation principle schematic diagram is as in figure 2 it is shown, being connected in series of break pin signal indicator 1, and power module realizes alternating current 220V and is converted into direct current 24V；K1 is the normally closed contact of relay, is connected with the display lamp of break pin signal indicator 1；K2 is the normal opened contact of relay, being connected with PLC module, PLC module realizes opening into function, control function, communication function, outputs function, and fiber optical transceiver can realize long-distance transmissions, switch converts optical signal into the signal of telecommunication, and host computer can realize real time monitoring function.When stator is obstructed, the break pin being enclosed within stator mechanical arm is cut off, and corresponding contact disconnects；K2 is become normally opened due to dead electricity from normally closed, meet PLC and open access point, PLC walks the flow process of inside, PLC outputs module and this information is transferred to fiber optical transceiver, fiber optical transceiver transmits information to switch again, switch transmits this information to computer, and computer screen display break pin signal indicator 1 is cut off, such that it is able to monitoring hydraulic turbine card color；K1 is become normally closed due to dead electricity from normally opened, connects break pin signal indicator 1 display lamp, and operations staff can check the information of cutting off now.
