Abstract
The utility model relates to the technical field of the special component or part of the hydraulic turbine of a high-speed liquid impact vane and is applied to judge whether a snipping pin is snipped or not. The utility model consists of a down-lead and a signal body and is characterized in that the signal body consists of a laser emitter (3) which is placed at the upper part inside the cavity of the snipping pin (1) and a laser receiver (7) which is placed at lower part inside the same cavity. The utility model solves the problem that the former announciator can not be repeatedly used. The utility model has the advantages of long service life and low manufacturing cost.
Description
Affiliated technical field
The utility model relates to water turbine special-purpose member or the part technical field that high-speed liquid impacts blade, is applied to the judgement whether break pin is cut off.
Background technique
Water turbine in hydro-electric power generating equipment is fixed by break pin with the connecting rod that links to each other with generator shaft by the blade connecting rod of high speed water jet impact.When the foreign material that come with stream caused blade rotation to be obstructed, break pin can be cut off, and two connecting rods are separated, and finished the effect of protection equipment.Produce this phenomenon other control task afterwards in order to finish, people insert one and cut off advertiser in the cavity of the y direction of break pin, it is made up of lead-in wire and signal body, the signal body is the hollow ceramic pipe of two ends sealing, and the cavity left and right side of pipe is coated with a silver powder lines of thin layers road symmetrically.Article two, the lower end of circuit is connected and conducting with silver powder thin layer on the bottom surface, and upper tip is connected with two signal leads respectively.During use, cut off in two signal lead Access Control circuits of advertiser, operating current flows out from a signal lead inflow and from another signal lead.When break pin fractureed, the signal body of cutting off advertiser was also fractureed, thereby operating current also interrupts, and control wiring just begins to respond the control of having set.This deficiency of cutting off advertiser is that whole signal body also breaks, and can not use repeatedly when cutting off the phenomenon generation.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of repeatedly used advertiser of cutting off that is applied to break pin is provided.
The purpose of this utility model can reach like this: a profit is applied to the advertiser of cutting off of break pin, form by lead-in wire and signal body, it is characterized in that the signal body is made up of top generating laser that is positioned at the break pin cavity and the laser pickoff that is positioned at same cavity bottom; Transmitter is made up of the circuit that solid luminescence device and current-limiting resistance are in series; This circuit is packaged into cylindrical that the solid luminescence device exposes with the engineering plastics injection molding, and the required DC electrical source the two poles of the earth of circuit are received the outside with line as lead-in wire; Receiver is by the corresponding photosensitive device of LED light emitting deivce that is adopted with transmitter and amplifier, sample resistance, divider resistance forming circuit; In this circuit photosensitive device with connect after sample resistance is connected and DC electrical source the two poles of the earth between, connect after the two divider resistances series connection and DC electrical source the two poles of the earth between, the potential point of sample resistance and the potential point of divider resistance link to each other with backward end with the end in the same way of the input end of operational amplifier respectively; Entire circuit is packaged into cylindrical that photosensitive device exposes with the engineering plastics injection molding, and the required DC electrical source the two poles of the earth of circuit are received the outside with the output line of line and operational amplifier as lead-in wire.
Transmitter and receiver use in opposite directions, are positioned at the two ends of break pin cylindrical cavity jointly.The solid luminescence device is meant the Semiconductor Lasers emission tube, infrared emission tube or other LED emission tubes etc.; Photosensitive device is meant photoresistor, photodiode, phototransistor, photovoltaic cell etc.
The utility model has following advantage compared to existing technology:
1, stable performance, durable in use;
2, operating cost is low, and easy maintenance is promoted easily.
Description of drawings
Fig. 1 is a mounting structure schematic representation of the present utility model.
1 is that break pin 3 is that transmitter 5 is that connecting rod A 7 is that receiver 9 is connecting rod B among the figure
Fig. 2 is the built-in circuti diagram of transmitter 3.
R1 is a light emitting diode solid luminescence device for current-limiting resistance D1
Fig. 3 is the built-in circuti diagram of receiver 7.
D2 for photosensitive device diode, R2 corresponding to Fig. 2 solid luminescence device be that sample resistance R3, R4 are operational amplifier for divider resistance A1
Embodiment
The new shape of this practicality is further described below in conjunction with accompanying drawing.Connecting rod A (5) in the hydro-electric power generating equipment is connected by break pin (1) with connecting rod B (9).Break pin (1) is a hollow steel pipe, is carved with easy mark of break at the middle part.Break pin in the reality (1) is sent out when dirt is cut off phenomenon and is always broken apart along this trace.Transmitter of the present utility model (3) and receiver (7) just are inserted in the cavity from the two ends of break pin (1) respectively.So the engineering plastics shell of transmitter (1) and receiver (7) is when injection molding, its pipe external diameter is cavity very little smaller therewith usually, and internal diameter then is advisable can include corresponding circuit board having built-in in.During encapsulation, epoxy resin is injected in the engineering plastics shell pipe, the power supply of circuit is drawn from an end of pipe with the output line of line and circuit, the other end then exposes solid luminescence device or photosensitive device.When making built-in circuit, as an embodiment, the parameter of each element is: the R1=360 Ω D1 of Fig. 2 is TLN225 infrared diode or TOLD9231M laser diode, and Vin is 1KHZ pulse amplitude 5V; The D2 of Fig. 3 is that TORU31 photodiode or TPS708 photodiode R2 are 20K Ω, and R3=R4=10K Ω, A1 are LM358, and VCC is direct current+5V.During installation, can be with boring one circular groove on break pin (1) the two-port inwall, at the mid-elasticity of groove " O " shape seal ring, and then transmitter (3) and receiver (7) inserted.
During work, transmitter (3) D1 that is positioned at break pin (1) cavity sends ray, and this ray is by Fig. 3 photosensitive device D2 response of corresponding receiver (7), and amplifier A1 exports the V0 value.After break pin (1) fracture, both dislocation of transmitter (3) and receiver (7), thus losing the ray contact, this moment, A1 output was different from the value of V0, and the variation of this value flows to other control circuit by the output pin of receiver.When changing break pin (1), receiver (7) and transmitter (3) can be taken off from the break pin (1) of damage and load onto use again.
Claims (1)
1, a kind of advertiser of cutting off that is applied to break pin is made up of lead-in wire and signal body, it is characterized in that the signal body is made up of top generating laser (3) that is positioned at break pin (1) cavity and the laser pickoff (7) that is positioned at same cavity bottom.
