The height of the guide frame 6 is larger than the water level drop so as to meet the working condition under the condition of large water level difference. The guide frame 6 is vertically arranged, the top elevation of the guide frame 6 is higher than the highest water level 6m, and the bottom elevation is lower than the lowest water level 1m, so that the requirement of the working range of the high-water-level-difference lower junction box platform 5 can be met. The cable drum 2 is a variable frequency cable drum 2 capable of accurately measuring the length of an output cable, the cable drum 2 is arranged on one side of the top of the tying pier 1, and the central elevation of the drum of the cable drum 2 is higher than the top elevation of the guide frame 6 by 1-2 m. The water level meter 7 is arranged at the top of the berth 1 and far away from the berth side, so that disturbance of the ship to the water surface is avoided as much as possible, the measurement accuracy is improved, the accurate measurement range of the water level meter 7 is 1-50 m, and the water level fluctuation range is larger than. The travel switch 8 adopts mechanical touch type, and the travel switch 8 is used for limiting the ascending of the electric box receiving platform 5 and initializing, namely resetting, the position of the electric box receiving platform 5. The electric box receiving platform 5 is arranged on the side edge of the berth 1 and can move up and down along the guide frame 6, and is used for bearing the electric box receiving 3 and supplying power receiving operation and passing for a shipman, and the electric box receiving platform 5 is used for bearing the electric box receiving 3 and supplying power receiving operation and passing for the shipman. The accurate measurement range of the radar range finder 9 is 0.1-50 m. The electric box 3 can move up and down along with the electric box platform 5 so as to conveniently supply power for ships at different water levels. The lifting winch 4 is used to lift and lower the trolley platform 5.
The controller 10 is arranged in the rear side management room, can systematically receive signals of the water level gauge 7, the travel switch 8 and the radar range finder 9, performs operation processing, and sends out instructions to control the cable drum 2 and the lifting winch 4 to work according to processing results.
The invention also provides a control method of the real-time matching system for the positions of the vertical shore power connection box and the power receiving ship, which comprises the following steps:
in the initial state, the electric box platform 5 is arranged at the top of the guide frame 6 and is contacted with the travel switch 8, and the lifting winch 4 and the cable drum 2 are in the initial state of zero setting, namely the height of the electric box platform 5 is The hoisting winch 4 and the cable drum 2 travel a distance s=0.
After the power receiving ship 11 is parked, a shipman applies for power consumption through the mobile phone app and reports ship information, and after the controller 10 receives a signal and is confirmed by a management party, the shore power system starts to work.
The controller 10 measures water level data according to the water level gauge 7And calculating the ship dry height h reported by the power receiving ship 11 to obtain the distance S required to descend by the power receiving box platform 5.
Wherein:
note that: epsilon 3 is the safety distance threshold (initial value of 0.3m, which can be determined according to practical test).
The controller 10 synchronously sends signals to the hoisting winch 4 and the cable drum 2 according to the calculation result, on one hand, the cable drum 2 is controlled to release the cable, and on the other hand, the hoisting winch 4 is controlled to release the steel wire rope, the speed Vtd of the two is consistent, the travel Std is the same, and the cable receiving platform 5 descends to the calculated distance S.
When descending, in order to avoid that the ship dry side height data is reported by mistake or the deviation is too large, the electric box platform 5 is submerged due to too much descending distance, the radar range finder 9 at the bottom of the electric box platform 5 can measure the distance L in real time and feed back to the controller 10, and the controller 10 calculates the height of the electric box platform 5 in real time according to the feedback information on one handOn the other hand, the elevation of the power receiving box platform 5 is calculated according to the descending distance StdAnd compared with the difference of the two, the accuracy of the descending distance is ensured, and on the other hand, the fact that the electric box receiving platform 5 cannot be immersed in water is ensured.
The specific algorithm for ensuring that the downstream distance Std is accurate is as follows:
when dH > epsilon 1, the actual speed and the design speed of Vtd are larger, the descending is excessive, and the value of Vtd should be reduced;
when dH < -epsilon 1, the actual speed and the design speed of Vtd are smaller, the downlink is smaller, and the value of Vtd should be increased;
When dH epsilon (-epsilon 1, epsilon 1), the downlink distance error is smaller, the actual speed basically accords with the design speed, and the Vtd value is not adjusted.
The specific algorithm for ensuring that the lug boss 5 is not immersed in water is as follows:
when L > epsilon 2, the electric box platform 5 has enough safety distance from the water surface, and continues to run;
when L is less than or equal to epsilon 2, the electric box platform 5 is too close to the water surface, and the electric box platform 5 stops descending.
Wherein, epsilon 1 and epsilon 2 are thresholds, the initial threshold value is 0.5, and the initial threshold value can be determined according to actual tests.
When the power receiving platform runs to a proper height, a shipman of the power receiving ship 11 drags the power receiving cable to the power receiving box platform 5, and the shipman gets power for the ship after docking with the power receiving box 3, and leaves the power receiving box platform 5 after power getting operation. At this time, the radar range finder 9 measures a distance l=l0 from the water surface.
In use, when the water level in the water areaWhen the ship rises, the ship rises along with the rising of the water level, the radar range finder 9 below the power receiving box platform 5 detects that the distance L from the water surface is smaller, the measured value is L1, when the variation range dL=L0-L1 exceeds the threshold epsilon 3, the controller 10 synchronously sends signals to the lifting winch 4 and the cable drum 2, on one hand, the cable drum 2 is controlled to recover the cable, on the other hand, the lifting winch 4 is controlled to control the steel wire rope to retract, the speed and the travel of the two are consistent, and the power receiving box platform 5 rises to the required height Su.
Su＝dL
Similarly, when the water level drops, the controller 10 controls the cable drum 2 and the lifting winch 4 to work, so that the height of the power receiving box platform 5 is always matched with the height of the power receiving ship 11.
When the power receiving ship 11 finishes using electricity, a shipman breaks away the power receiving cable from the power receiving box 3, the cable drags to be separated from the power receiving box platform 5, after the safety is confirmed by a rear management personnel, the controller 10 controls the cable drum 2 and the lifting winch 4 to work, the power receiving box platform 5 is lifted to the top of the guide frame 6, when the power receiving box platform 5 touches the travel switch 8, the operation is stopped, and the lifting winch 4 and the cable drum 2 are initialized, namely, the height reset value of the power receiving box platform 5 isThe hoisting winch 4 and the cable drum 2 travel distance reset to s=0.
The embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many forms may be made by those having ordinary skill in the art without departing from the spirit of the present invention and the scope of the claims, which are to be protected by the present invention.
