[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model is a kind of electric ship power supply equipment with replaceable power, including an electric ship power supply equipment body 1, a plurality of battery replacement compartments 2 are arranged inside the electric ship power supply equipment body 1, a battery pack is arranged inside the battery replacement compartment 2, a plurality of support plates 9 are symmetrically arranged on both sides of the electric ship power supply equipment body 1, and a limit assembly is arranged on the support plate 9, and the limit assembly includes a push rod 5, a bent rod 7, a driving block 8, a base 15 and a plug rod 13, the push rod 5 passes through the electric ship power supply equipment body 1, and the inner end of the push rod 5 is provided with a The positioning plate 3 is used to limit the battery pack. A positioning ring 6 is fixedly arranged at the outer end of the push rod 5. One end of the bent rod 7 is rotatably connected to the positioning ring 6. A driving shaft 11 is fixedly arranged at the front end of the driving block 8. The driving shaft 11 is rotatably connected to the other end of the bent rod 7. A fixed shaft 10 fixed to the upper end of the support plate 9 is rotatably arranged at the rear end of the driving block 8. A toggle rod 14 is fixedly arranged on one side of the driving block 8. The base 15 is fixed on one side of the fixed shaft 10. The insertion rod 13 passes through the toggle rod 14 and is inserted into the interior of the base 15.

[0024] In this structure, the size of the battery swap compartment 2 is larger than the size of the battery pack, so that the battery pack can be easily placed in the battery swap compartment 2, and the battery pack will not bump into the main body 1 of the electric ship power supply equipment during placement, so that the battery pack itself is not easily damaged, which can increase the service life of the battery pack and avoid waste of resources;

[0025] When the battery pack needs to be removed, open the door panel on the main body 1 of the electric boat power supply equipment, and then pull out the battery pack in the battery replacement compartment 2;

[0026] After the battery pack is placed inside the battery swap compartment 2, by toggling the toggle rods 14 on both sides of the battery swap compartment 2, the drive block 8 can be rotated around the fixed axis 10, and the bent rod 7 can push the push rod 5 to move through the positioning ring 6, so that the two positioning plates 3 can limit the battery pack in the battery swap compartment 2, and the battery pack can be docked with the designated charging equipment in the battery swap compartment 2. The charging equipment here is similar to the charging equipment in the battery swap cabinet on the market, so there is no need to make too much description about the designated charging equipment in the battery swap compartment 2 here, which can make the battery pack easy to assemble in the battery swap compartment 2.
