Detailed description of the invention
Also by reference to the accompanying drawings the application is described in further detail below by specific embodiment."front", "rear" described in literary composition, "left", "right", " on ", D score all makes a concession the laying state of ice power hydraulic-driven movable dam control system for reference with having in accompanying drawing.
As shown in Figure 1, the embodiment of the application provides one and has yielding ice power hydraulic-driven movable dam control system, comprises fuel tank 100, in-line 101, return line 102, emergency pressure relief pipeline 103, moves back ice pipeline 104, solenoid operated directional valve 105, pressure sensor 106 and control centre's (not shown).
In-line 101, return line 102, pressure relief pipe 103 and move back ice pipeline 104 and all have one end to be communicated with fuel tank 100, and the other end of three is all connected with the hydraulic jack of hydraulic-driven movable dam 200.Wherein, in-line 101 is for carrying out fuel feeding to each hydraulic jack of hydraulic-driven movable dam 200, and return line 102 falls dam operation for daily oil return, and pressure relief pipe 103 is then for realizing the operation of fast prompt drop dam when there is flood.Move back the ice pressure that ice pipeline 104 is then mainly used in by alleviating the fine setting of dam facing suffered by dam facing.
Below the primary structure alleviating ice pressure is described in detail.Solenoid operated directional valve 105 is arranged on and moves back on ice pipeline 104, for controlling the open and-shut mode moving back ice pipeline 104.Pressure sensor 106 is for monitoring the hydraulic oil pressure in the hydraulic jack of hydraulic-driven movable dam 200, and pressure sensor 106 can adopt pressure switch.When dam facing is subject to ice pressure, hydraulic oil pressure can raise, once hydraulic oil pressure exceedes set upper limit value, pressure switch just can close, and sends pressure monitoring signal to control centre (such as PLC).Control centre can control solenoid operated directional valve 105 and open after receiving the monitor signal of pressure sensor, make to move back ice pipeline and be in channel status, there is the hydraulic oil in cylinder can flow in fuel tank 100 by moving back ice pipeline, thus reduce hydraulic oil pressure and make dam facing hypsokinesis, alleviate ice pressure.When hydraulic oil pressure drops in normal range (NR), pressure switch disconnects, and now control centre then controls solenoid operated directional valve 105 and closes, and cuts off and moves back ice pipeline 104, makes dam facing stop hypsokinesis.
When carrying out the operation reducing ice pressure, the hydraulic oil pressure in hydraulic jack needs to remain in the reasonable scope, if the too fast dam facing attitude that likely causes of pressure release is abnormal.For this reason, be also provided with holding overflow valve 107 moving back on ice pipeline 104 in the present embodiment, now, solenoid operated directional valve 105 is positioned at the downstream of holding overflow valve 107, for controlling the open and-shut mode of the unloading port of holding overflow valve 107.
Holding overflow valve 105 can adjust the oil pressure of hydraulic oil and keep, and when the unloading port of holding overflow valve 105 opens, hydraulic oil can return fuel tank 100 via holding overflow valve 105, thus reduces the hydraulic oil pressure in hydraulic jack.And when hydraulic oil pressure is lower than oil pressure value set by holding overflow valve 105, even if unloading port is in opening, holding overflow valve 105 still can stop hydraulic oil to be discharged, and ensures that oil pressure is in zone of reasonableness with this.
In the present embodiment, move back ice pipeline 104 just for controlling the operation alleviating ice pressure, and dam operation is fallen for daily, then controlled by return line 102.Particularly, return line 102 arranges a hydraulic control one-way valve 108, this hydraulic control one-way valve 108 is in unidirectional cutoff state at ordinary times, stops hydraulic oil to return fuel tank by hydraulic jack.And after applying certain pressure to hydraulic control one-way valve 108, the cut-off state of hydraulic control one-way valve 108 can be changed, thus make hydraulic oil get back in fuel tank 100 by return line 102 smoothly, thus realize falling dam operation.
The Stress control of hydraulic control one-way valve 108 can be realized by reversal valve 109 (as solenoid operated directional valve), reversal valve 109 possesses an oil-in and two oil-outs, wherein, oil-in and an oil-out are communicated with in-line 101, for being the hydraulic jack fuel feeding of hydraulic-driven movable dam 200 normal through in-line 101, another oil-out of reversal valve 109 is then communicated to hydraulic control one-way valve 108.When needing the cut-off state changing hydraulic control one-way valve 108, by reversal valve 109, the hydraulic oil in in-line 101 can be guided to hydraulic control one-way valve 108, for hydraulic control one-way valve 108 pressurizes, thus change the cut-off state of hydraulic control one-way valve 108 pairs of return lines 102.
In-line 101 can drive oil pump 111 from the oil pumping of fuel tank 100 inside by motor 110, and when hydraulic oil pressure reaches prescribed limit, pressure switch closes, and control centre controls motor 110 and reversal valve 109 fuel cut-off.In order to prevent oil pressure too high, can also an overflow valve 112 being set on in-line 101, unnecessary hydraulic oil is turned back in fuel tank 100 along overflow valve 112.In addition, can also be filtered by the mode arranging strainer 113 near one end of fuel tank 100 at in-line 101.
When hydraulic-driven movable dam promptly must fall dam because of reasons such as floods, needs can make hydraulic-driven movable dam 200 decline fast to carry out flood discharge, and be no matter return line 102 or move back running of hydraulic power oil requirement when ice pipeline 104 all cannot bear fast prompt drop dam, in the control system of the hydraulic-driven movable dam 200 therefore provided at the present embodiment, also specialized designs has emergency pressure relief pipeline 103, and is provided with emergency pressure relief valve 114 on emergency pressure relief pipeline 103.When there is flood, the hydraulic oil in hydraulic jack can be made to return in fuel tank 100 quickly through emergency pressure relief pipeline 103 by opening emergency pressure relief valve 114, thus the hydraulic oil pressure in hydraulic jack is reduced rapidly, reaching the object on fast prompt drop dam.In order to prevent hydraulic oil from flowing back to hydraulic jack from emergency pressure relief pipeline 103 is reverse, emergency pressure relief line check valve 115 can also be set on emergency pressure relief pipeline 103 unidirectional cutoff is carried out to emergent pressure relief pipe 103.
For different functions, there is some difference in the design standard meeting of oil pipe line, but, if every bar oil pipe line is built all separately, not only can increase design-build cost, also can increase volume and the complex structure degree of system, difficulty is manufactured to associated construction process.Consider return line 102 and move back ice pipeline 104 and be middle low flow velocity designing requirement, therefore in order to simplify structure as far as possible, return line 102 and the structure of moving back ice pipeline 104 have carried out integrating simplifying by the present embodiment.Particularly, draw a total oil return pipe 116 by fuel tank 100, return line 102 and the tail end moving back ice pipeline 104 are all connected on total oil return pipe 116.Shorten return line 102 like this and move back the length of the independent setting unit of ice pipeline 104, simplify oil pipe line structure.Now, a return filter 117 can also be set on total oil return pipe 116 to via return line 102 and move back the hydraulic oil that ice pipeline 104 returns and unify to filter.
In the present embodiment, in-line 101, return line 102, pressure relief pipe 103 and move back ice pipeline 104 and all need to be communicated with the hydraulic jack of hydraulic-driven movable dam 200, if be communicated with all separately, also certainly will can increase the complex structure degree of hydraulic jack.Therefore in order to simplify pipeline structure, a unified transfer pipeline 118 can be set, in-line 101, return line 102, pressure relief pipe 103 and move back ice pipeline 104 and be all connected with transfer pipeline 118, and then be connected with hydraulic jack by transfer pipeline 118 is unified.Because transfer pipeline 118 both can fuel feeding, again for oil return, therefore in order to prevent hydraulic oil from directly turning back in in-line 101 by transfer pipeline 118, in-line 101 also needing, and an in-line one way valve 119 is set and had carried out unidirectional cutoff.
In the present embodiment, if there is multiple dam facing, in order to realize the independent control to each dam facing, in-line 101, return line 102, pressure relief pipe 103 and move back ice pipeline 104 house steward all can be set and many arms carry out independent control to each dam facing respectively, and each dam facing also should be equipped with corresponding solenoid operated directional valve 105, pressure sensor 106, holding overflow valve 107, hydraulic control one-way valve 108, reversal valve 109 etc., and concrete set-up mode repeats no more.
What the present embodiment provided have makes a concession ice power hydraulic-driven movable dam control system and achieves the static ice pressure automatically reducing dam facing and bear, and slows down the object that movable dam overall structure is destroyed because of ice.Without the need to optional equipment deicing facility, also personnel need not carry out icebreaking service, reduce labour intensity, improve safety, also possess the features such as structure is simple, energy consumption is extremely low, easy to operate, long service life, environmental protection simultaneously.
The foregoing is only the preferred embodiment of the application, be not limited to the application, for a person skilled in the art, the application can have various modifications and variations.Within all spirit in the application and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in the application.
