Description

Technical Field

[0001] This utility model relates to the field of power supply and distribution equipment technology, and in particular to a power supply and distribution equipment for ships. Background Technology

[0002] Ship power supply and distribution equipment is an important component of the ship's electrical system. It is responsible for distributing the electrical energy generated by the power generation equipment to various electrical devices to ensure the normal operation of the ship.

[0003] Shipboard power supply and distribution equipment mainly includes main switchboards, emergency switchboards, distribution switchboards, and shore power systems. These devices collectively constitute the ship's power network, ensuring a stable power supply and safe operation. According to authorization announcement number "CN207595233U", a shipboard power system is disclosed, applicable to ships. This ship includes uninterruptible power supply (UPS) equipment and electric propulsion. The shipboard power system includes a generator set, lithium battery packs, a switchboard, a battery management module, and a power conversion module. The generator set serves as the primary power source, and the lithium battery pack serves as an auxiliary power source. The lithium battery pack provides power to the ship's UPS equipment. When the battery management module detects insufficient lithium battery power, it controls the switchboard to distribute the power generated by the generator set to charge the lithium battery pack. This embodiment of the shipboard power system provides continuous and stable power to the ship's UPS equipment, thereby reducing the ship's operating costs.

[0004] Currently, when ships are conducting power distribution operations, not only are there main power supply modules to maintain the ship's operation, but also emergency power supply modules for power outages. However, in most cases, the core power modules and emergency power modules are fixed in one area of ​​the ship, making it impossible to flexibly transfer the emergency power modules when local emergency use is needed. At the same time, the emergency power modules not only need to have the ability to distribute power, but also need to have auxiliary power functions to further improve the use of power distribution equipment. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a power supply and distribution equipment for ships.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a power supply and distribution equipment for ships, including a conventional power supply and distribution cabinet, a plate base is fixedly installed on the lower end of one side of the conventional power supply and distribution cabinet, a base is inserted into the plate base, and the plate base and the base are fixedly installed by a threaded knob;

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Reference Figures 1-5A power supply and distribution device for ships includes a conventional power distribution cabinet 1. A plate base 11 is fixedly installed on the lower side of one side of the conventional power distribution cabinet 1. A base 12 is inserted into the plate base 11. The plate base 11 and the base 12 are fixedly installed by a threaded knob 18. An emergency power distribution cabinet 13 is inserted and connected to the plate base 11 through the base 12. This allows the conventional power distribution cabinet 1 to cooperate with the emergency power distribution cabinet 13 for circuit control when the power supply is normal. In the event of a sudden power outage, the emergency power distribution cabinet 13 can replace the conventional power distribution cabinet 1 for power distribution. Furthermore, the plate base 11 and the base 12 can be separated by removing the threaded knob 18, thereby enabling the separation of the conventional power distribution cabinet 1 and the emergency power distribution cabinet 13.

[0029] An emergency power distribution cabinet 13 is fixedly installed on the top of the base 12. A cable routing hole 17 is provided on one side of the emergency power distribution cabinet 13. When the emergency power distribution cabinet 13 is moved to other areas for auxiliary power distribution, the cable routing hole 17 can be used to introduce and lead out the line.

[0030] Bearings 14 are symmetrically distributed and fixed at the lower end of the base 12. A shaft 15 is inserted through the bearing 14 and is interference-fitted. A wheel 16 is mounted at the lower end of the shaft 15. The wheel 16 can roll and move when the emergency power distribution cabinet 13 needs to be moved. The shaft 15 rotates based on the bearing 14, which facilitates the omnidirectional movement of the wheel 16.

[0031] The plate base 11 has a threaded sleeve symmetrically embedded inside, and the surface of the base 12 has a threaded groove corresponding to the position of the threaded sleeve. The threaded knob 18 is threadedly installed with the corresponding threaded sleeve and threaded groove. By separating the threaded knob 18 from the threaded groove and threaded sleeve respectively, the plate base 11 and the base 12 can be disengaged.

[0032] Among them, several winding posts 2 are fixedly distributed on one side of the emergency power supply distribution cabinet 13. The surface of the winding post 2 is covered with a tightening cap 21. The winding post 2 can wind and store the excess length of wire introduced into the cable hole 17. The tightening cap 21 can wrap and tighten the wire wound on the winding post 2.

[0033] The tightening cap 21 has symmetrically distributed notches 22 on its surface. A pull head 23 is fixedly installed at the end of the tightening cap 21 away from the emergency power distribution cabinet 13. At least two notches 22 can ensure the stability of the incoming and outgoing lines when the lines are wound and tightened.

[0034] The tightening cap 21 has an elastic clip 24 fixedly installed on its inner side, and the winding post 2 has a slot 25 at its end. The elastic clip 24 and the slot 25 are interlocked and fixed. The shape of the elastic clip 24 and the inner shape of the slot 25 are both regular hexagons, and the elastic clip 24 is made of rubber material. By cooperating with the slot 25, the tightening cap 21 and the winding post 2 can be stably assembled.

[0035] An insulating base 3 is fixedly installed on the upper end of the emergency power distribution cabinet 13. The insulating base 3 is made of high-strength plastic material. A storage battery 31 is inserted inside the insulating base 3. The insulating base 3 can insulate the storage battery 31 from the shell of the emergency power distribution cabinet 13. The storage battery 31 can provide the required power when auxiliary power supply or temporary power is needed.

[0036] The emergency power distribution cabinet 13 has positioning sleeves 32 fixedly installed on both sides of the upper end of the shell by brackets. Positioning pins 33 are slidably connected inside the positioning sleeves 32. Springs 34 are wound around the surface of the positioning pins 33. The two ends of the springs 34 are fixedly installed to the end of the positioning pins 33 and the end face of the positioning sleeves 32, respectively. The positioning pins 33 are of the hand-pulled type and can be inserted and connected to the positioning seats 35 through the positioning pins 33. Thus, the emergency power distribution cabinet 13 can be fixed to the insulating seats 3 from both sides.

[0037] The insulating base 3 has a positioning seat 35 fixedly installed on its side wall. The end of the positioning pin 33 away from the spring 34 slides into the interior of the positioning seat 35. When the insulating base 3 needs to be installed, it is placed on the emergency power distribution cabinet 13 and the two positioning pins 33 are pulled outward so that the emergency power distribution cabinet 13 can be connected with the insulating base 3. When the position of the positioning pin 33 corresponds to the position of the positioning seat 35, the positioning pin 33 can be inserted into the interior of the positioning seat 35 by the reset effect of the spring 34, thereby fixing the insulating base 3 to the emergency power distribution cabinet 13.

[0038] In practice

[0039] In this solution, a plate base 11 is fixedly installed on the lower side of the conventional power distribution cabinet 1. A base 12 is inserted inside the plate base 11. The base 12 is fixedly connected to the plate base 11 by a threaded knob 18. The threaded knob 18 passes through the threaded sleeve of the plate base 11 and the threaded groove of the base 12 to achieve a tight fit between the two. When the conventional power distribution cabinet 1 is supplying power normally, the emergency power distribution cabinet 13 connects to the plate base 11 through the base 12 to form a complete power supply system, ensuring stable circuit control. In case of a sudden power outage, the emergency power distribution cabinet 13 can immediately take over the power supply task to ensure uninterrupted power supply. When it is necessary to separate the two, simply remove the threaded knob 18 to detach the plate base 11 from the base 12, and the emergency power distribution cabinet 13 can be moved out for easy maintenance or redeployment.

[0040] The emergency power distribution cabinet 13 has bearings 14 symmetrically installed at the lower end of the base 12. The bearings 14 have an interference fit with a shaft 15. The lower end of the shaft 15 is equipped with wheels 16, which allows the emergency power distribution cabinet 13 to move freely. The wheels 16 achieve omnidirectional rotation based on the bearings 14, which facilitates rapid transfer to different areas. The cable routing hole 17 is opened on one side of the emergency power distribution cabinet 13 for introducing and leading out power lines. The winding post 2 is fixed on the side of the emergency power distribution cabinet 13 for storing excess wires. The tightening cap 21 covers the winding post 2 and fixes the inlet and outlet positions through the notch 22. The pull head 23 facilitates the installation and removal of the tightening cap 21. The elastic clip 24 engages with the slot 25 at the end of the winding post 2 to ensure that the tightening cap 21 is stable.

[0041] An insulating base 3 made of high-strength plastic is fixed to the upper end of the emergency power distribution cabinet 13 for installing the battery 31, preventing the battery 31 from directly contacting the cabinet and causing a short circuit. The positioning sleeve 32 is fixed to both sides of the housing of the emergency power distribution cabinet 13 by a bracket, and the positioning pin 33 is slidably connected inside. The spring 34 connects the positioning pin 33 and the positioning sleeve 32 to provide a reset elastic force. The positioning seat 35 is fixed to the side wall of the insulating base 3. When the insulating base 3 is placed in place, the positioning pin 33 is pulled outward, aligned with the positioning seat 35, and then released. The spring 34 pushes the positioning pin 33 to insert into the positioning seat 35, realizing the quick locking of the insulating base 3.
