Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shore power equipment, in particular to a shore power plugging structure with power-off self-disconnection. Background Art
[0002] Shore power means that a ship berthing at a port shuts down the auxiliary generator on the ship and instead uses the clean energy provided by the port side to supply power to the main on-board systems, which is a mode of drawing electricity from the land power grid.
[0003] In the existing shore power plugging structure, when the shore power is cut off, it is not convenient to lock the wiring terminal, which is likely to cause the wiring terminal to come into contact with the wiring port of the ship again, resulting in safety accidents. Summary of the Utility Model
[0004] The utility model solves the problems in the related technologies and provides a shore power plugging structure with power-off self-disconnection. The sliding rod and the coil body form a magnetic field structure. When the wiring terminal at one end of the sliding rod is disconnected from the wiring port of the ship, the electromagnetic field in the first through hole relative to the coil body disappears, and the other end of the sliding rod is attracted by the magnetic force of the second magnetic ring in the second through hole, driving the coil body to move in the direction relative to the second through hole. The limiting column limits the moved coil body, effectively avoiding the contact between the wiring terminal on the sliding rod and the wiring port of the ship.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions: A shore power plugging structure with power-off self-disconnection includes a fixed base, a support base arranged on the upper end surface of the fixed base, a coil body arranged on the upper end surface of the support base, a wire mounting hole arranged on the coil body for connecting an electric wire, a sliding rod connected to the coil body, and an adjusting component for adjusting the sliding rod. A wiring terminal is arranged at one end of the sliding rod relative to the first through hole.
[0006] The adjusting component includes a first through hole arranged at one end of the support base, a first magnetic ring arranged in the first through hole, a second through hole arranged at the other end of the support base, a second magnetic ring arranged in the second through hole, a limiting column slidably connected to the fixed base, a chute arranged on the fixed base and adapted to the limiting column, and a support spring arranged in the chute for adjusting the limiting column. Positive and negative magnetic blocks are arranged in the first magnetic ring and the second magnetic ring.
[0007] By adopting the above technical solution, the sliding rod and the coil body form a magnetic field structure. When the wiring terminal at one end of the sliding rod is disconnected from the wiring port of the ship, the electromagnetic field in the first through hole relative to the coil body disappears, and the other end of the sliding rod is magnetically adsorbed by the second magnetic ring in the second through hole, driving the coil body to move in the direction relative to the second through hole. The limiting post limits the moved coil body, thus effectively preventing the wiring terminal on the sliding rod from contacting the wiring port of the ship.
[0008] Optionally, one end of the coil body relative to the first through hole is fixedly connected to the sliding rod, and one end of the coil body relative to the second through hole is slidably connected to the sliding rod.
[0009] By adopting the above technical solution, such a design facilitates the coil body to drive the sliding rod to move synchronously when moving horizontally, thus preventing the wiring terminal on the sliding rod from contacting the wiring port of the ship.
[0010] Optionally, the lower end surfaces of the coil body are respectively arranged as inclined surfaces, and the inclined surfaces of the coil body are arranged in opposite mirror images.
[0011] By adopting the above technical solution, such a design facilitates the coil body to slide off the limiting post.
[0012] Optionally, one end of the limiting post relative to the coil body is arranged as a spherical surface, and the outer periphery of the spherical surface is arranged as a smooth arc surface.
[0013] By adopting the above technical solution, it is convenient for the coil body to slide off the limiting post, thereby realizing the limiting function of the limiting post on the coil body.
[0014] Optionally, one end of the support spring is fixedly connected to the bottom end of the inner cavity of the chute, and the other end of the support spring is fixedly connected to the lower end surface of the limiting post.
[0015] By adopting the above technical solution, the support spring facilitates the change of the up and down position of the limiting post, thereby facilitating the coil body to slide above the limiting post, and thus facilitating the limiting post to realize the limiting of the coil body.
[0016] Optionally, it further includes a buffer spring arranged inside the coil body and sleeved on the outer periphery of the sliding rod, and a sliding ring connected to the buffer spring. The sliding ring is slidably connected to the sliding rod, the inner side of the sliding ring is fixedly connected to one end of the buffer spring, and the other end of the buffer spring is fixedly connected to the inner side of one end of the coil body relative to the first through hole.
[0017] By adopting the above technical solution, it is convenient to support both inner ends of the coil body through the buffer spring, thereby effectively ensuring the tension of the coil body at the node, effectively ensuring the stability of the connection between the terminal and the ship interface, and when the power is off, the other end of the sliding rod is magnetically adsorbed by the second magnetic ring in the second through hole, driving the coil body to move in the direction relative to the second through hole, and the limit post limits the moved coil body, thereby effectively preventing the terminal on the sliding rod from contacting the wiring port of the ship.
[0018] Optionally, it further includes a limit retaining ring arranged on the sliding rod, and the outer diameter of the limit retaining ring is larger than the inner diameter of the second through hole.
[0019] By adopting the above technical solution, the design of the limit retaining ring effectively prevents the sliding rod from detaching from the support base, thereby effectively ensuring the safety performance of the present utility model.

In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0031] In the description of the present invention, it should be understood that the orientation terms such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" generally indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description.

[0034] As Figures 1 to 4 shown, a shore power plugging structure with power-off self-disconnection includes a fixed base 1, a support base 2 disposed on the upper end surface of the fixed base 1, a coil body 3 disposed on the upper end surface of the support base 2, a wire mounting hole 31 disposed on the coil body 3 for connecting an electric wire, a sliding rod 6 connected to the coil body 3, and an adjusting assembly for adjusting the sliding rod 6. A wiring terminal is disposed at one end of the sliding rod 6 relative to the first through hole 21.
[0035] In one embodiment, as Figure 3 and Figure 4As shown in the figure, the adjusting component includes a first through hole 21 provided at one end of the support base 2, a first magnetic ring 211 provided in the first through hole 21, a second through hole 22 provided at the other end of the support base 2, a second magnetic ring 221 provided in the second through hole 22, a limit post 51 slidably connected to the fixed base 1, a chute 50 provided on the fixed base 1 and adapted to the limit post 51, and a support spring 52 provided in the chute 50 for adjusting the limit post 51. Positive and negative magnetic blocks are provided in the first magnetic ring 211 and the second magnetic ring 221. In the present utility model, the sliding rod 6 and the coil body 3 form a magnetic field structure. When the wiring terminal at one end of the sliding rod 6 is disconnected from the wiring port of the ship, the electromagnetic field in the first through hole 21 relative to the coil body 3 disappears, and the other end of the sliding rod 6 is magnetically adsorbed by the second magnetic ring 221 in the second through hole 22, driving the coil body 3 to move in the direction relative to the second through hole 22. The limit post 51 limits the moved coil body 3, thereby effectively preventing the wiring terminal on the sliding rod 6 from contacting the wiring port of the ship.
[0036] In one embodiment, as Figure 2 and Figure 4 shown, one end of the coil body 3 relative to the first through hole 21 is fixedly connected to the sliding rod 6, and one end of the coil body 3 relative to the second through hole 22 is slidably connected to the sliding rod 6. Such a design facilitates the coil body 3 to drive the sliding rod 6 to move synchronously when moving horizontally, thereby preventing the wiring terminal on the sliding rod 6 from contacting the wiring port of the ship.
[0037] In one embodiment, as Figure 3 and Figure 4 shown, the lower end surfaces of the coil body 3 are respectively provided as inclined surfaces, and the inclined surfaces of the coil body 3 are arranged in a relative mirror image. Such a design facilitates the coil body 3 to slide off the limit post 51.
[0038] In one embodiment, as Figure 1 and Figure 4 shown, one end of the limit post 51 relative to the coil body 3 is provided as a spherical surface, and the outer periphery of the spherical surface is provided as a smooth arc surface. Such a design facilitates the coil body 3 to slide off the limit post 51, thereby realizing the limiting effect of the limit post 51 on the coil body 3.
[0039] In one embodiment, as Figure 3 and Figure 4 shown, one end of the support spring 52 is fixedly connected to the bottom end of the inner cavity of the chute 50, and the other end of the support spring 52 is fixedly connected to the lower end surface of the limit post 51. The support spring 52 facilitates driving the limit post 51 to change its vertical position, thereby facilitating the coil body 3 to slide above the limit post 51, and thus facilitating the limit post 51 to realize the limiting of the coil body 3.
[0040] In one embodiment, as Figure 3 and Figure 4 shown, in order to ensure the tension of the coil body 3 at the node, it further includes a buffer spring 41 disposed inside the coil body 3 and sleeved on the outer periphery of the sliding rod 6, and a sliding ring 411 connected to the buffer spring 41. The sliding ring 411 is slidably connected to the sliding rod 6, and the inner side of the sliding ring 411 is fixedly connected to one end of the buffer spring 41. The other end of the buffer spring 41 is fixedly connected to the inner side of one end of the coil body 3 relative to the first through hole 21. Such a design facilitates the support of both inner ends of the coil body 3 by the buffer spring 41, thereby effectively ensuring the tension of the coil body 3 at the node, effectively ensuring the stability of the connection between the terminal and the ship interface, and when powered off, the other end of the sliding rod 6 is magnetically adsorbed by the second magnetic ring 221 in the second through hole 22, driving the coil body 3 to move in the direction relative to the second through hole 22, and the limit post 51 limits the moved coil body 3, thereby effectively preventing the terminal on the sliding rod 6 from contacting the wiring port of the ship.
[0041] In one embodiment, as Figure 1 and Figure 3 shown, in order to prevent the end of the sliding rod 6 away from the terminal from detaching from the support base 2, it further includes a limit retaining ring 61 disposed on the sliding rod 6. The outer diameter of the limit retaining ring 61 is greater than the inner diameter of the second through hole 22. The design of the limit retaining ring 61 effectively prevents the sliding rod 6 from detaching from the support base 2, thereby effectively ensuring the safety performance of the present invention.
[0042] In this embodiment, during use, the sliding rod 6 and the coil body 3 form a magnetic field structure. When the terminal at one end of the sliding rod 6 is disconnected from the wiring port of the ship, the electromagnetic field in the first through hole 21 relative to the coil body 3 disappears, and the other end of the sliding rod 6 is magnetically adsorbed by the second magnetic ring 221 in the second through hole 22, driving the coil body 3 to move in the direction relative to the second through hole 22, and the limit post 51 limits the moved coil body 3, thereby effectively preventing the terminal on the sliding rod 6 from contacting the wiring port of the ship.
[0043] The above is the preferred embodiment of the present invention. Those skilled in the art to which the present invention pertains can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the above specific embodiments, and any obvious improvements, substitutions or variations made by those skilled in the art based on the present invention all fall within the protection scope of the present invention.
