Background technique
At present, need maintenance service after wind-driven generator uses or be maintenance, wind wheel need be locked usually during maintenance, otherwise wind wheel rotation meeting damages the maintenance man breaking down, abnormally dangerous.But the wind wheel of wind power generating set lock is to realize lock and move back lock by artificial at present, inconvenient operation, and also usually lock can not be locked or be moved back fully to lock fully because operate miss causes wind wheel, and Security is not high.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of suitable convenience, simple to operate, safe wind-driven generator group wind-wheel locking device.
The utility model is realized by following measure:
A kind of wind-driven generator group wind-wheel locking device of the present utility model, comprise wind wheel lock pin and wind wheel lock collar, described wind wheel lock collar is provided with the hole clipping that slips into or skid off when the wind wheel lock pin advances lock or moves back lock, it is characterized in that: also comprise driving with the wind wheel lock pin being connected and can driving the wind wheel lock pin to advance lock or move back the power plant of lock and be used to control the control gear of power plant.
Above-mentioned control gear is connected with near switch, describedly is used for the position signal of wind wheel lock pin is sent to control gear near switch, can judge accurately whether the wind wheel lock pin puts in place fully, improves Security.
Above-mentioned power plant comprise oil hydraulic cylinder and are communicated with oil hydraulic cylinder and for oil hydraulic cylinder provides the hydraulic station of power, the piston rod of described oil hydraulic cylinder drives and connects the wind wheel lock pin by oil circuit that oil circuit is provided with solenoid valve, and control gear is connected with solenoid valve.
Be easy-to-operat, above-mentioned control gear is provided with into the lock button and moves back the lock button.
The beneficial effects of the utility model are: 1. operation the time only need be pressed button, and the control by control gear just can realize the locking and unlocking, and is simple to operate, the saving manpower.2. judge whether to lock fully or move back fully lock by testing signal, it is more accurate to detect.3. the degree of accuracy that locks and move back lock is higher, safe.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the utility model operation method flow chart.
Among the figure: 1 advances to lock button, and 2 move back the lock button, 3 control gear, and 4 hydraulic stations, 5 near switch sensing point I, and 6 near switch sensing point II, 7 oil hydraulic cylinders, 8 piston rods, 9 wind wheel lock collars, 10 wind wheel lock pins, 11 hole clippings.
Embodiment
As shown in Figure 1, 2, 3, a kind of wind-driven generator group wind-wheel locking device of the present utility model, comprise present already used wind wheel lock pin 10 and wind wheel lock collar 9, wind wheel lock 9 is provided with hole clipping 11, when wind wheel lock pin 10 advances to lock, wind wheel lock pin 10 slips into hole clipping 11, thereby with 9 lockings of wind wheel lock collar, wind wheel can not rotate.When wind wheel lock pin 10 moved back lock, wind wheel lock pin 10 skidded off hole clipping, thereby with 9 releases of wind wheel lock collar, wind wheel recovers to rotate.Wind wheel lock pin 10 drives and connects power plant, and power plant can drive wind wheel lock pin 10 and advance lock or move back lock to the wind wheel lock collar.Power plant are by control gear 3 control operations.Control gear 3 is connected with near switch, is used for the position signal of wind wheel lock pin 10 is sent to control gear near switch.Control gear 3 is provided with into lock button 1 and moves back lock button 2.Power plant can adopt hydraulic power unit, comprise oil hydraulic cylinder 7 and be communicated with and provide the hydraulic station 4 of power by oil circuit with oil hydraulic cylinder 7 for oil hydraulic cylinder 7, the piston rod 8 of oil hydraulic cylinder 7 drives and connects wind wheel lock pin 10, the break-make of control gear 3 control hydraulic stations 4 solenoid valves, hydraulic station 4 was oil hydraulic cylinder 7 fuel feeding, hydraulic station 4 position of rest oil hydraulic cylinders 7 fuel feeding during closed electromagnetic valve when solenoid valve was opened.
Its working principle is:
When advancing to lock button 1 and press, give control gear 3 one signals, control gear 3 is judged the moving direction of wind wheel lock pin 10 according to the current button of pressing, export control command then and drive corresponding solenoid valve to hydraulic system, solenoid valve gets to be opened after electric, the pressure of hydraulic system will enter oil hydraulic cylinder 7 along corresponding oil circuit A, drive wind wheel lock pin 10 to the direction motion that locks or move back lock by piston rod 8, when the state near switch sensing point I 5 is a digital signaling zero, when being digital signal 1 near the state of switch sensing point II 6, expression wind wheel lock has put in place and locking fully fully, this time-control apparatus 3 will stop to 4 drive signals of hydraulic station, the wind wheel lock pin keeps current location, waits for the arrival of next signal.Same reason, when moving back lock button 2 when pressing, control gear 3 can send control signal according to current button signal and drive hydraulic station 4 corresponding solenoid valve and open, thereby oil circuit B is opened, and piston rod 8 is moved back the direction motion of lock to wind wheel lock pin 10.When the state near switch sensing point I 5 is a digital signal 1, when being digital signaling zero near the state of switch sensing point II 6, expression wind wheel lock pin 10 has withdrawed from fully, and this time-control apparatus 3 will stop to 4 drive signals of hydraulic station.The wind wheel lock pin keeps current location, waits for the arrival of next signal.
May further comprise the steps:
A. judge whether the wind wheel lock collar locks, if not, carry out step b; If carry out step c;
B. press into lock button, control gear control power plant promote the wind wheel lock pin and advance lock, and carry out steps d;
C. press and move back the lock button, control gear control power plant promote the wind wheel lock pin and move back lock, and carry out step e;
D. detect the wind wheel lock pin and whether advance lock and put in place fully, if not, then return step b, if control gear cuts out power plant;
E. detect the wind wheel lock pin and whether move back lock and put in place fully, if the result then returns step c, if control gear cuts out power plant for not.
Above-mentioned power plant are hydraulic power unit, and control gear is by the break-make control hydraulic power unit operation of the solenoid valve on the control oil channel.Among steps d and the e, whether use is advanced lock near switch detection wind wheel lock pin or is moved back lock and put in place fully, and digital signal is sent to control gear.
The foregoing description is described to be in order to specify this patent; though describe by specific term in the literary composition; but can not limit the protection domain of this patent with this; being familiar with the personage of this technical field can be after the spirit of understanding this patent and principle change or revises it and reach equivalent purpose; and this equivalence change and modification all should be covered by the claim scope and define in the category.
