Description
Technical field
The power system of a kind of ocean range vessel of the utility model, particularly relates to a kind of Ship Steering Autopilot and to meet an urgent need extension and retraction system, for improve the emergency treatment ability of stabilizer, elevator system reliability.
Background technology
Boats and ships ocean navigation cycle of sailing is long, and navigable zone sea situation is severe, and equipment working environment is poor, provides higher requirement to Stability of Ship.Certain ship uses 704 institutes to produce JQ-8 type stabilizer 4, and this type stabilizer hydraulic efficiency pressure system use jury pump is as the method for emergent folding and unfolding.When mair motor fault, by jury pump, stabilizer is regained.But boats and ships are in ocean navigation, main electrical breakdown, a point electronic box dead electricity will cause jury pump, electromagnetic valve to work, and stabilizer cannot be regained.
Stabilizer by artificial mode folding and unfolding stabilizer, does not directly affect the guarantee of ship's navigation and Stability of Ship.So be necessary to study this defect analysis, line correlation of going forward side by side is transformed, and guarantee that boats and ships are normally exercised the function, safety of ship is reliable.
Utility model content
Technical problem to be solved in the utility model provides a kind of Ship Steering Autopilot to meet an urgent need extension and retraction system for above-mentioned prior art, the operation of the return-to-zero up and down of stabilizer, unblock, folding and unfolding fin can be completed under emergency conditions, improve equipment dependability, improve the successful that ocean range vessel is executed the task.
The technical scheme in the invention for solving the above technical problem is: a kind of Ship Steering Autopilot is met an urgent need extension and retraction system, this system comprises controllable capacity pump, servopump, slippage pump and jury pump four pump groups, composition turns fin oil circuit respectively, servo oil circuit, repairing oil circuit and emergent folding and unfolding oil circuit, by three hydraulic rams, fin rotation cylinder respectively, what locking cylinder and folding and unfolding oil cylinder realized corresponding stabilizer turns fin, locking and draw-in and draw-off function, force pump is installed additional in debit's electromagnetic valve entrance position of described emergent folding and unfolding oil circuit, with exporting, the first ball valve and the second ball valve are installed at the export pipeline of described locking cylinder and the import of folding and unfolding oil cylinder respectively.
Compared with prior art, the utility model has the advantage of:
When not changing stabilizer hardware configuration, stabilizer is installed additional to the mode of artificial emergent folding and unfolding, the operation of the return-to-zero up and down of stabilizer, unblock, folding and unfolding fin can be completed under emergency conditions, improve equipment dependability, improve the successful that ocean range vessel is executed the task.
Accompanying drawing explanation
Fig. 1 is hydraulic scheme of the present utility model.
Fig. 2 is control system diagram of circuit of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of Ship Steering Autopilot in the present embodiment is met an urgent need extension and retraction system, this system comprises controllable capacity pump, servopump, slippage pump and jury pump four pump groups, composition turns fin oil circuit, servo oil circuit, repairing oil circuit and emergent folding and unfolding oil circuit respectively, by three hydraulic rams, be fin rotation cylinder respectively, locking cylinder and folding and unfolding oil cylinder realize corresponding stabilizer turn fin, locking and draw-in and draw-off function.
As shown in Figure 2, when ship navigates by water in stormy waves, angular velocity gyro in fin stabilizer, detects ship rolling angular velocity signal, and this signal is electric signal, through a series of process, amplification, the conversion of electric liquid, fin is driven to turn over a corresponding angle, fin produces " lift " under flow action, the corner equal and opposite in direction of port and starboard fin, and direction is contrary, form a moment (balancing torque) contrary with wave moment direction, thus the roll angle of ship is reduced.
In order to realize, to the artificial emergent folding and unfolding of stabilizer, installing force pump additional in debit's electromagnetic valve entrance position of emergent folding and unfolding oil circuit, installing the first ball valve and the second ball valve at the export pipeline of described locking cylinder and the import of folding and unfolding oil cylinder respectively with exporting.Under stabilizer normal operation, the second ball valve is opened, and the first ball valve is closed, and now systemic-function is consistent with before transformation.
Under emergency conditions, when mair motor, jury pump dead electricity, close the second ball valve, open the first ball valve, force pump can be used to complete the operation of the upper and lower return-to-zero of stabilizer, unblock, folding and unfolding fin, elevator system reliability, and specific embodiments is as follows:
1, return-to-zero operation up and down:
Use thimble operation return-to-zero electromagnetic valve, return-to-zero valve core of the electromagnetic valve is moved return-to-zero position up and down, and operation force pump can make the upper and lower return-to-zero of stabilizer.
2, unlocking operation:
Close the second ball valve, open the first ball valve, operation force pump can make locking cylinder action, closes the first ball valve, locking cylinder can be made to remain on released state after locking.
3, folding and unfolding fin operation:
Use thimble operation folding and unfolding electromagnetic valve, make folding and unfolding valve core of the electromagnetic valve to receipts fin, put fin position and move, operation force pump can make stabilizer receive fin, put fin.
In addition to the implementation, the utility model also includes other embodiments, the technical scheme that all employing equivalents or equivalent substitute mode are formed, within the protection domain that all should fall into the utility model claim.
