It provides power to various onboard equipment and is equipped with the necessary electronic control and protection devices to ensure proper operation. The box typically consists of load switches and fuses, and can handle four to ten loads. It is located near the loads and easily accessible for maintenance.

[0003] Chinese utility model patent publication number CN219305187U discloses a ship electrical box fixing bracket, comprising a fixing base, the surface of which contacts the electrical box body, the outer surface of which is fixedly connected to an insert, the fixing base being provided with a disassembly mechanism, and the fixing base being fixedly connected to a heat conducting base. A fixing base with mounting ears is provided, and a limiting sleeve is provided on the fixing base so that the electrical box body can be placed into the limiting sleeve. Inserts are provided on both sides of the electrical box body, and then a disassembly mechanism is provided on the fixing base. The disassembly mechanism contains a spring-retractable latch that can be inserted into the insert. By controlling the clutch between the latch and the insert, the electrical box body can be disassembled and assembled, eliminating the need for frequent disassembly of bolts, which is more convenient. Furthermore, a lever is provided on the latch, and a limiting plug is provided on the lever to limit the latch.

[0004] The above-mentioned ship electrical box fixing bracket facilitates the fixing and disassembly of the electrical box through the disassembly and assembly mechanism, but it will cause floating instability during the navigation of the ship.

[0030] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 4The utility model provides a technical solution: a limiting support device for an electrical box, comprising a base 1, a thrust spherical roller bearing 2 fixedly mounted on the base 1 at a central position on one side close to the electrical box, a connecting column 21 welded on the central position on one side of the electrical box close to the thrust spherical roller bearing 2 and fixedly connected to the inner ring of the thrust spherical roller bearing 2, and a shock absorbing assembly 3 and a displacement assembly 4 arranged at the four corners of the base 1 close to the electrical box, wherein the side of the base 1 has an ear piece 11.

[0032] Among them, the shock absorbing assembly 3 includes an air spring shock absorber 31 fixedly mounted on the base 1 and a contact plate 32 welded on the electrical box at a position above the air spring shock absorber 31 , and one end of the air spring shock absorber 31 close to the contact plate 32 contacts the contact plate 32 .

[0033] When in use, the device and the electrical box are laid down on a flat surface, and the thrust spherical roller bearing 2 on the base 1 is aligned with the center of the bottom of the electrical box. Then, the connecting column 21 fixedly connected to the inner ring of the thrust spherical roller bearing 2 is welded to the center of the bottom of the electrical box. After that, the displacement assembly 4 is installed at the four corners of the electrical box, and then the electrical box and the base 1 are lifted up. Finally, the base 1 is fixed to the designated position on the ship through the ear piece 11 using an expansion bolt or a stud bolt. When the ship is sailing, the floating of the ship drives the base 1 to shake, and the thrust spherical roller bearing 2 is tilted. The tilted end of the base 1 drives the air spring shock absorber 31 to approach the electrical box. When it contacts the contact plate 32, it is squeezed and generates damping to offset the stress. Then, it separates from the contact plate 32 as it shakes, and the shaking base 1 drives other air spring shock absorbers 31 to contact the corresponding contact plate 32, thereby absorbing the shaking during the operation of the ship in repeated cycles, reducing the amplitude of the electrical box, and protecting the electrical box.

[0034] It should be noted that the air spring shock absorber 31 is a rubber air spring of model 2B9-220, which is more suitable for the working environment of a ship due to its long service life, good cold resistance, excellent air tightness, waterproofness, and electrical insulation.

[0035] Furthermore, the displacement assembly 4 includes a ball head rolling groove 41 fixedly mounted on the base 1 at a corresponding corner position close to one side of the electrical box, a telescopic member 42 rotatably connected to the end of the ball head rolling groove 41 away from the base 1, and a flange seat 43 fixedly connected to the electrical box near the ball head rolling groove 41 and connected to the end of the telescopic member 42 away from the ball head rolling groove 41; as the base 1 shakes, the ball head rolling groove 41 shakes, causing the telescopic member 42 to displace, connecting the electrical box to prevent the electrical box from detaching from the base 1, and absorbing the shaking during the operation of the ship through the displacement of the telescopic member 42, thereby limiting the electrical box.

[0036] Furthermore, the telescopic member 42 includes a ball head 423 rotatably mounted on the ball head rolling groove 41, a movable rod 422 fixedly connected to the end of the ball head 423 away from the ball head rolling groove 41, a telescopic sleeve 421 sleeved on the end of the movable rod 422 away from the ball head 423, and a flange 424 fixedly connected to the end of the telescopic sleeve 421 away from the movable rod 422, wherein the telescopic sleeve 421 is slidably connected to the movable rod 422, and the through-hole position corresponding to the flange 424 on the flange seat 43 is provided with a fixing bolt 431, a hexagonal nut 432 is screwed on the fixing bolt 431; it is installed through the flange plate 424 on the telescopic sleeve 421 and the flange seat 43 on the electrical box and locked with the hexagonal nut 432. When the telescopic member 42 is pressurized by the base 1, since the telescopic member 42 is fixedly installed on the electrical box and movably connected to the base 1 through the ball head 423, when the base 1 shakes, a relative displacement occurs between it and the electrical box, driving the movable rod 422 to tilt through the ball head 423 and slide and retract with the telescopic sleeve 421.

[0037] In addition, there is a buffer spring inside the telescopic sleeve 421, and the two ends of the buffer spring are fixedly connected to the movable rod 422 and the telescopic sleeve 421 respectively; when the movable rod 422 and the telescopic sleeve 421 slide and contract, the buffer spring will be squeezed to absorb the stress caused by the shaking of the base 1, and provide damping to enable the base 1 to quickly reset, thereby further improving the stability of the electrical box during ship operation and providing protection.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
