[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3A ship energy-saving bulbous bow installation platform includes a frame 1 for placing the bulbous bow, the frame 1 includes cross beams 11 and longitudinal beams 12 that are arranged at intervals and fixedly connected, and the cross beams 11 and the longitudinal beams 12 are fixedly connected to form the frame 1 for placing the bulbous bow, which is convenient for the actual installation of the bulbous bow. The frame also includes guide rails 2 that are spaced apart at the bottom of the cross beams 11 and positioning mechanisms 3 that are spaced apart at the top of the frame 1 for positioning the bulbous bow. The guide rails 2 are arranged corresponding to the position of the ship, so that the position of the frame 1 is arranged corresponding to the position where the bulbous bow is installed on the ship.

[0025] In the specific implementation, the position of the guide rail 2 is set corresponding to the position where the bulbous bow of the ship is installed, that is, the guide rails 2 arranged at intervals are symmetrically arranged at the center of the position where the bulbous bow of the ship is installed, so that the center line of the frame 1 and the center line of the position where the bulbous bow of the ship is installed are on the same vertical line, so that after the bulbous bow is placed on the frame 1 through the positioning mechanism 3, it is convenient to install the bulbous bow on the bow of the ship; When placing the bulbous bow on the top of the frame 1, an external lifting device is usually required for operation. After the bulbous bow is placed on the top of the frame 1, when the frame 1 is moved to the position where the bulbous bow is installed on the ship, the frame 1 is usually pushed along the guide rail 2 by a forklift or the like. This is all existing technology and will not be described in detail here.

[0026] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the positioning mechanism 3 comprises: The positioning assembly 31 is symmetrically arranged with respect to the center point of the frame 1 and is used to position the bulbous bow from both sides of the bulbous bow so that the position of the bulbous bow is arranged correspondingly to the position of the frame 1, and thus to the position of the ship, so as to install the bulbous bow to the bow of the ship. The positioning assembly 31 includes: A base 312 is fixedly arranged on the top of the longitudinal beam 12, and a support plate 311 arranged in an inclined manner is hingedly arranged on the top of the base 312; The positioning seat 313 is movably arranged on the top of the crossbeam 11, and the top of the positioning seat 313 is sleeved with a positioning plate 314 which is symmetrically arranged with respect to the center point of the positioning seat 313, and the top of the positioning plate 314 is hinged to the top of the support plate 311, so that the bulbous bow can be positioned from both sides through the positioning seat 313 and the positioning plate 314, and the positioning plate 314 is supported by the support plate 311.

[0027] The positioning component 31 also includes: The shielding cover 315 is fixedly arranged on the top of the positioning seat 313 and sleeved on the side of the positioning plate 314 away from the support plate 311. The shielding cover 315 and the side of the positioning seat 313 away from the support plate 311 are vertically aligned, and a space for the positioning plate 314 to move vertically is reserved on the inner side of the shielding cover 315, and a space for the support plate 311 to rotate is reserved on the side where the positioning plates 314 are close to each other.

[0028] In a specific implementation, when the bulbous bow is placed on the top of the frame 1 by an external lifting device, the distance between the positioning seats 313 on both sides of the top of the same crossbeam 11 is adjusted by the adjustment component 32 according to the size of the bulbous bow, so that the bulbous bow can be placed on the top of the frame 1 along the space between the positioning seats 313. In the process of placing the bulbous bow, the bulbous bow is positioned from both sides of the bulbous bow by the positioning plate 314 and the positioning seat 313, and the bulbous bow is positioned while limiting the inclination of the bulbous bow, so that the center of the bulbous bow corresponds to the center of the frame 1, so that the center of the bulbous bow corresponds to the center of the position where the bulbous bow is installed on the ship, so that the bulbous bow can be installed on the bow of the ship; When placing the bulbous bow on the top of the frame 1, the spacing between the positioning seats 313 can be made larger than the size of the bulbous bow by adjusting the assembly 32, so that the bulbous bow can enter between the positioning seats 313. As the bulbous bow is continuously lowered, the positioning seats 313 are gradually brought closer to each other to position the bulbous bow. While positioning the bulbous bow by the positioning plate 314, the positioning seat 313 and the shielding cover 315, the positioning plate 314 and the positioning seat 313 are supported by the support plate 311 to improve the stability of the positioning plate 314 and the positioning seat 313, avoid the weight of the bulbous bow and the poor support of the top of the positioning plate 314, etc., which affects the stability of the positioning of the bulbous bow, and improve the stability of the bulbous bow limit. By hingedly setting both ends of the support plate 311, and enabling the positioning plate 314 to move on the top of the positioning seat 313, the inclination angle of the support plate 311 and the position of the positioning plate 314 are adjusted simultaneously during the movement of the positioning seat 313, so as to facilitate practical use; The bottom of the positioning seat 313 is fitted with the side wall of the cross beam 11 by providing the first positioning groove 316 and the second positioning groove 13, so as to limit the movement of the positioning seat 313 on the side wall of the cross beam 11, so as to improve the stability of the vertical installation of the positioning seat 313 and the stability of the positioning of the bulbous bow; By setting the shielding cover 315 and making the shielding cover 315 and the side of the positioning seat 313 away from the support plate 311 vertically aligned, it is avoided that the position of the top of the positioning seat 313 blocks the bulbous bow, thereby avoiding affecting the stability of the positioning of the bulbous bow, and the inner side of the shielding cover 315 is reserved with a space for vertical movement with the positioning plate 314, thereby avoiding affecting the position adjustment of the positioning seat 313, and the side of the positioning plates 314 close to each other is reserved with a space for the support plate 311 to rotate, so that when adjusting the position of the positioning seat 313, the support plate 311 rotates along the space between the positioning plates 314, thereby avoiding affecting the support of the support plate 311 to the positioning plate 314; A groove for fitting the positioning plate 314 is formed on the top of the positioning seat 313, and the depth of the groove is greater than the maximum moving distance of the positioning seat 313, so as to limit the separation of the positioning plate 314 from the positioning seat 313, and facilitate the actual movement and use of the positioning plate 314; The heights of the positioning seat 313, the positioning plate 314, the support plate 311 and the shielding cover 315 can be designed according to the position of the bulbous bow, and are not specifically limited here. After the bulbous bow is positioned, the contact positions of the shielding cover 315, the positioning seat 313 and the bulbous bow can be welded to further improve the stability of the positioning.

[0029] See also Fig. 9 and Fig.10 , the self-locking assembly 317 includes: The mounting frame 3176 is fixedly mounted on the top of the base 312.

A second electromagnet 3178 is sleeved on the inner wall of the first moving groove 3174. The first electromagnet 3177 and the second electromagnet 3178 are close to each other on the same magnetic pole. The first electromagnet 3177, the second electromagnet 3178 and the first moving groove 3174 are all designed in an annular shape so that space is reserved at the center of the top of the fixing seat 3175. The ring 3173 is fixedly disposed on the top of the second electromagnet 3178 and faces the pawl 3172 to adjust the meshing of the ratchet 3171 and the pawl 3172 through the first electromagnet 3177 and the second electromagnet 3178.
