[0052] For a better understanding of the technical solution of the present invention, the present invention will be described in detail below with reference to the drawings.

[0053] The present invention provides a positioning device for a marine mooring seat, which includes a transverse positioning member 1, a longitudinal positioning member 2, and a horizontal arc member 3. The transverse positioning member 1 is vertically arranged (that is, the plate surface of the transverse positioning member 1 is perpendicular to the horizontal plane). The longitudinal positioning member 2 is vertically arranged on one side surface of the transverse positioning member 1. The horizontal arc member 3 is arranged on both sides of the longitudinal positioning member 2 and is respectively connected to the transverse positioning member 1 and the longitudinal positioning member 2. A first groove 4 is formed at the top of the transverse positioning member 1, and a second groove 5 is formed at the top of the longitudinal positioning member 2. The groove depth of the first groove 4 is equal to the groove depth of the second groove 5.

[0054] Preferably, the longitudinal positioning member 2 is vertically fixed at the center of one side surface of the transverse positioning member 1.

[0055] When the positioning device for the marine mooring seat is fixed on the deck to assist in installing the mooring seat 9, the first groove 4 on the transverse positioning member 1 should be able to cover the mooring seat installation hole 8 formed on the deck, and the second groove 5 on the longitudinal positioning member 2 should be able to cover half of the aperture of the mooring seat installation hole 8 formed on the deck.

[0056] In this embodiment, both the transverse positioning member 1 and the longitudinal positioning member 2 are selected as flat plates. Of course, in other embodiments, the transverse positioning member 1 and the longitudinal positioning member 2 can also be designed into other shapes or structures. However, regardless of the shape or structure, the groove depth of the first groove 4 on the transverse positioning member 1 should be equal to the groove depth of the second groove 5 on the longitudinal positioning member 2.

[0057] The specific designed depths of the first groove 4 and the second groove 5 should be designed according to the installation requirements of the mooring base. In this embodiment, since the mooring base needs to protrude 3 mm from the bottom of the deck after installation, therefore, the groove depths of the first groove 4 and the second groove 5 are both designed to be 3 mm.

[0058] The horizontal arc member 3 can be set as an arc-shaped round bar or an arc-shaped plate (quarter circle plate). The horizontal arc member 3 is used to connect the transverse positioning member 1 and the longitudinal positioning member 2 to improve the structural stability of the entire marine mooring base positioning device. The horizontal arc member 3 is perpendicular to the transverse positioning member 1 and the longitudinal positioning member 2.

[0059] The present invention also provides a method for positioning and installing a marine mooring base, which specifically includes the following steps:

[0070] Preferably, the mooring pedestal installation hole 8 is a special-shaped hole, and its hole wall includes a vertical surface extending downward from the deck top surface and an inclined surface connected to the vertical surface and inclined downward toward the hole center. The groove width of the first groove 4 of the mooring pedestal positioning device is greater than the lower hole diameter of the mooring pedestal installation hole 8, and the groove width of the second groove 5 is greater than the lower hole radius of the mooring pedestal installation hole 8.

[0071] The mooring pedestal installation hole 8 can also be opened as a common round hole.

[0072] S4. Fix the above-mentioned mooring pedestal positioning device from below the deck at the position where the mooring pedestal installation hole 8 is opened on the lower surface of the deck.

[0073] After the mooring pedestal positioning device is installed, the first groove 4 on its transverse positioning member 1 should cover the mooring pedestal installation hole 8, and at the same time, the second groove 5 on its longitudinal positioning member 2 should cover half of the hole diameter of the mooring pedestal installation hole 8.

[0074] S5. Place the mooring pedestal 9 into the mooring pedestal installation hole 8 from above the deck, and make the bottom of the mooring pedestal sit on the bottom of the first groove 4 and the second groove 5 (that is, make the base of the mooring pedestal abut against the bottom of the first groove 4 and the second groove 5).

[0075] S6. Weld and fix the mooring base 9 and the deck 7 into one body, and remove the mooring base positioning device after welding.

[0076] So far, the installation of the mooring base 9 is completed. Then, install other components on the deck to form a deck section. After lifting the deck section off the deck jig 6, grind off the laying pads 6-4 on the deck.

[0077] It should be clear that the described embodiments are only part of the embodiments of the present invention, rather than all embodiments.
