Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary devices for ship water intake, and particularly relates to an auxiliary device for accurately positioning ship water intake. Background Art

[0002] As is well known, during the ship water intake process, a ship chock is usually used. The ship chock can firmly support the ship, enabling the ship to form a support in the water or leave the water surface by a certain height. It can provide stable support, ensuring that the ship does not shake or tilt, and guaranteeing the safe progress of the corresponding operations on the ship.

[0003] After retrieval, the invention patent with the Chinese patent publication number CN112357011A discloses a ship launching skid for shipbuilding, which is generally described as including a base plate. On the upper part of the base plate, vertical side plates are fixedly welded on both the left and right sides. In the middle of the opposite sides of the two side plates, chutes are opened along their lengths. In the middle of the two side plates, a moving groove communicating with the chutes is opened along their lengths. On the outer sides of the upper parts of the two side plates, the lower part of the protective plate is movably hinged through a third pin shaft. When in use, when ensuring that the airbag column rolls under the pressure of the hull, the airbag column can slide in the chutes and the moving groove through the cooperation of the concave support arm, the connecting rod, and the roller, ensuring smooth movement following the movement of the bed body. At the same time, we also retrieved the invention patent with the Chinese patent publication number CN117227935A, which discloses a shore connection structure for a transverse wedge ship chock, which is generally described as including a connecting rod, a baffle, a shore connection member, a wedge ship chock connection member, a gasket, a fastening nut, and a shore connection member seat. There are several shore connection member seats, and they are arranged along the edge of the shore close to the ship chock. The shore connection member seats are cast in the shore concrete structure, and the upper surface of the shore connection member seats is flush with the shore. There is a concave opening inside the shore connection member seats. The shore connection member is fixed on the shore connection member seats. Both sides of the shore connection member are steel structures. A semicircular hole is opened on the shore side where the shore connection member is fixed. The wedge ship chock connection member corresponds to the shore connection member, and the wedge ship chock connection member is fixed on the wedge ship chock. The wedge ship chock connection member and the shore connection member are a support structure for supporting and positioning the connecting rod. When in use, the ship chock is rigidly connected to the shore, providing a fixed ship chock surface when the ship is on the ship chock through the ship moving system.

[0004] Although the above-mentioned ship launching skid for shipbuilding can realize the auxiliary launching of the ship, it is difficult to be applicable to ship water intake, and its functionality needs to be further enriched. The above-mentioned shore connection structure for a transverse wedge ship chock only provides a shore connection structure matching the transverse wedge ship chock. Although it can be used for the connection of the transverse wedge ship chock to the shore, its coverage of the content of the transverse wedge ship chock is less, and the introduction of the corresponding positioning structure between the transverse wedge ship chock and the ship is also relatively lacking, and its practicability needs to be further strengthened.

[0039] The pressure sensor 31 in this embodiment is equipped with a central control unit and a current controller, and the central control unit and the current controller are electrically connected to each other. The current controller is electrically connected to the external lead wire 24. The pressure sensor 31, the central control unit, and the current controller are all conventional devices well-known to those skilled in the art and purchased on the market. In the present invention, we only use them and do not improve their structures and functions. Their setting methods, installation methods, and electrical connection methods can be debugged and operated by those skilled in the art as long as they follow the requirements of their user manuals, and will not be elaborated here.

[0040] In summary, the working principle of the auxiliary device for accurately positioning the ship during water intake is as follows: during use, first, the auxiliary device for accurately positioning the ship during water intake is installed in a supporting manner at the use position. During the installation process, the slope installation surface 42 should be sorted out first, and then the track 41 should be installed relative to the slope installation surface 42. The traveling wheels 4 are installed to support the track 41, and finally, the wedge-shaped ship frame connector 1 is installed corresponding to the traction device. Through the operation of the traction device, the wedge-shaped ship frame 3 can move uphill or downhill relative to the track 41. The traction device can adopt the solution in the invention patent with the publication number of CN117227935A mentioned in the background technology, or other suitable solutions. After the overall installation of the auxiliary device for accurately positioning the ship during water intake is completed in terms of structure, the power supplies of the pressure sensor 31, the central control unit, and the current controller are turned on, and the vertical rod 7 is rotated relative to the horizontal adjustment rod 6 to be erected by rotating the drive shaft 15. At this time, the state is as shown in the appendix Figure 1 As shown. Select a sufficient number of the auxiliary devices for accurately positioning the ship during water intake according to the specific length of the ship. Considering the specific situation of the ship, the application quantity of the magnet adsorption positioning structure can be adjusted adaptively. As shown in the appendix Figure 12 Figure 8 shows a schematic diagram of the layout and installation of four wedge-shaped ship frame bodies supporting two magnet adsorption positioning structures. When the ship takes in water, first, the traction device is used to control the wedge-shaped ship frame 3 to move downhill along the track 41, so that the wedge-shaped ship frame 3 sinks into the water and has a sufficient depth in the water, and this depth should be greater than the draft depth of the ship. Then, the ship to be taken in water is driven to directly above the wedge-shaped ship frame 3. Next, the relative position between the wedge-shaped ship frame 3 and the ship is finely adjusted to make the permanent magnet 33 approach the ship until the permanent magnet 33 magnetically adsorbs on the ship. The power supply of the spiral wire 23 in the electromagnet is turned on to make the magnetic field generated by the electromagnet act on the ship. The positioning pin 26 that forms the relative limit between the vertical rod 7 and the lifting frame 20 is pulled out. Then, the reading of the pressure sensor 31 is detected, and the relationship between the strength change of the current controlled by the corresponding current controller is set according to the change range of the reading of the pressure sensor 31.

[0041] Furthermore, the uphill movement of the wedge frame 3 relative to the track 41 is achieved through the operation of the traction equipment. During this process, due to the magnetic attraction of the electromagnet on the ship, the ship can follow the movement of the wedge frame 3, and because the magnetic attraction of the electromagnet on the ship only provides auxiliary positioning for the ship, and cannot simply rely on the magnetism of the electromagnet to support the overall gravity of the ship, so when the wooden block 47 that rises synchronously with the wedge frame 3 has not yet provided auxiliary support for the bottom of the ship, the electromagnet will accompany the ship to form a relative stillness, and the lifting frame 20 will form a relative height reduction relative to the vertical pole 7, that is, the electromagnet can only assist the ship to form a horizontal movement along with the wedge frame 3, while the vertical movement will Compensation is formed by the relative sliding between the lifting frame 20 and the vertical pole 7. During this process, due to the action of the electromagnet, the relative fit between the lifting frame 20 and the ship is maintained until the wooden block 47 fully supports the ship. During the process of the wooden block 47 coming into contact with the bottom of the ship until the full support, since the wedge frame 3 is constantly moving along the track 41, and the ship will enter the state of being supported by the wedge frame 3 from floating on the water surface, the structure formed by the vertical pole 7 and the horizontal adjustment rod 6 will form an auxiliary limit for the ship. During this process, the electromagnet will adjust the magnetic strength according to the state of the ship. When the ship tilts away from the vertical pole 7, the magnetic attraction between the permanent magnet 33 and the ship will pass through the protective box 34, the connecting ball 36 and the spherical sleeve 35. The transmission makes the outrigger 28 have a movement tendency to be pulled out of the outer opening slot 29, thereby reducing the pressure of the outrigger 28 on the pressure sensor 31. According to the pressure reduction value of the pressure sensor 31, the central control machine identifies it and controls the current in the spiral wire 23 to increase through the current controller, thereby achieving the purpose of strengthening the electromagnetic magnetic field, so as to increase the magnetic attraction of the electromagnet on the ship, thereby achieving the purpose of overcoming the ship's tilting away from the vertical pole 7, and after the ship is no longer tilted, the value of the pressure sensor 31 will return to the original value, and the current connected to the corresponding electromagnet will also be restored, so as to improve the safety and energy saving effect. After the ship is launched and the ship is supported by external auxiliary equipment, it is necessary to control the permanent magnet 33 relative to When the ship is separated, first cut off the control power of the pressure sensor 31, the central control machine and the current controller, rotate the drive shaft 15, and under the cooperation of the driving bevel gear 16 and the driven bevel gear ring 17, the rotating drive shaft 15 will form a rotational drive for the threaded rod 11. Since the threaded rod 11 and the telescopic cylinder 9 have a relative threaded connection relationship, the rotating threaded rod 11 will cause the overall length of the threaded rod 11 and the telescopic cylinder 9 to form a corresponding change, and then achieve the rotational drive of the vertical rod 7 relative to the transverse adjustment rod 6, control the rotation direction of the threaded rod 11, and increase the overall length of the threaded rod 11 and the telescopic cylinder 9, so as to achieve the rotational fall of the vertical rod 7 relative to the transverse adjustment rod 6, so as to promote the permanent magnet 33 to move away from the ship.Facilitate the overcoming and invalidation of the relative magnetic force between the permanent magnet 33 and the ship.

[0042] Furthermore, taking an 80-meter barge as an example, the specific parameter standards of the auxiliary device for accurately positioning the ship upstream in actual use are as follows: 6 wedge-shaped ship frames 3 and 3 magnet adsorption positioning structures are used. Among the 6 wedge-shaped ship frames 3, magnet adsorption positioning structures are arranged on every other wedge-shaped ship frame 3. The corresponding relationship between the wedge-shaped ship frame 3 and the transverse adjustment rod 6 and the ship's molded breadth is: 1 / 2 the length of the wedge-shaped ship frame 3 + the extended length of the transverse adjustment rod 6 = 1 / 2 the ship's molded breadth. The length of the vertical rod 7 is 1m - 1.5m, and the maximum attraction of a single electromagnet is 2T.

[0043] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
