Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A shore power socket box for docks includes a base 1, with a socket box body 2 fixedly connected to the top of the base 1. Protective cover assemblies 3 are hinged to both sides of the socket box body 2. An automatic power-off protection assembly 4 is fixedly connected to the top of the inner side of the socket box body 2. The automatic power-off protection assembly 4 includes a mounting base 41, with a limit switch body 42 fixedly connected to the bottom of the mounting base 41. A connecting base 43 is fixedly connected to the adjusting end of the limit switch body 42. A trigger rod 44 is bolted to the inner side of the connecting base 43. The rear end of the trigger rod 44... A trigger block 45 is fixedly connected to the top of the mounting base 41, and an insect repellent and protective mechanism 46 is fixedly connected to the top of the mounting base 41 via a connecting rod. The insect repellent and protective mechanism 46 includes a liquid storage box 461, an absorbent sponge 462 is fixedly fixed to the top of the inner side of the liquid storage box 461, an installation shaft 463 is fixedly connected to the bottom of the inner side of the liquid storage box 461, a sealing plate 464 is rotatably connected to the outside of the installation shaft 463, a corrugated elastic element 465 is fixedly connected to one side of the top of the sealing plate 464, and an extrusion element 466 is fixedly connected to the other side of the top of the sealing plate 464.

[0017] As a further implementation of this solution, the protective cover assembly 3 includes a cover plate 31. The outer wall of the cover plate 31 has a movable groove 32. A hinge 33 is fixedly connected to the outer wall of the cover plate 31. An auxiliary plate 34 is hinged to one side of the hinge 33. The position of the auxiliary plate 34 corresponds to the position of the movable groove 32. A cable guide groove 35 is provided on the surface of the auxiliary plate 34. When it is necessary to lay cables, the auxiliary plate 34 can be opened. The cable guide groove 35 on its surface and the movable groove 32 form a continuous cable guiding channel, which facilitates the laying of cables in different directions. This solves the problem of limited space and easy tangling of cables in traditional socket boxes. At the same time, the setting of the hinge 33 ensures the stability and flexibility of the opening and closing of the auxiliary plate 34. As a further implementation of this solution, a gas spring telescopic rod 5 is installed below the automatic power-off protection component 4. The gas spring telescopic rod 5 is rotatably connected to the main body 2 of the electrical socket box. The telescopic end of the gas spring telescopic rod 5 is rotatably connected to the middle of the inner wall of the cover plate 31. When the telescopic end of the gas spring telescopic rod 5 extends, it pushes the cover plate 31 to rise smoothly with a uniform force, avoiding the cover plate 31 from colliding with the main body 2 of the electrical socket box due to excessive opening speed, which may cause damage or safety hazards. When the cover plate 31 is closed, the gas spring telescopic rod 5 can also provide a buffer force to make the cover plate 31 close slowly, which not only reduces the noise when closing, but also prevents the internal electrical components from being impacted by the rapid closing of the cover plate 31, effectively extending the overall service life of the socket box. As a further implementation of this solution, both sides of the electrical socket box body 2 are fixedly connected with perforated junction boxes 6. The outer side of the perforated junction box 6 is inclined, which helps rainwater to flow down the inclined surface and prevents rainwater from accumulating. Both sides of the outer wall of the perforated junction box 6 are provided with wire-passing holes 7 that are connected to the electrical socket box body 2. The position of the wire-passing holes 7 corresponds one-to-one with the position of the wire-fixing groove 35. The cable can be smoothly introduced into the wire-passing hole 7 through the wire-fixing groove 35 and then enter the interior of the electrical socket box body 2, making the cable arrangement more orderly and facilitating later maintenance and repair, and also reducing the safety risks caused by messy cables. As a further implementation of this solution, the inner side of the trigger rod 44 is provided with an anti-slip groove, and the front end of the trigger rod 44 is rotatably connected to a roller 47 through a connecting shaft. The top of the inner side of the cover plate 31 is fixedly connected to a pressure plate 36, which is located in front of the roller 47. The pressure plate 36 and the roller 47 rotate in cooperation, and the pressure plate 36 can drive the roller 47 to rotate more smoothly, thereby accurately controlling the rotation angle of the trigger rod 44 and ensuring that the limit switch body 42 can realize the switching between power off and power on in a timely and accurate manner. As a further implementation of this solution, the sealing plate 464 is located above the trigger block 45, the top of the corrugated elastic element 465 is fixedly connected to the inner wall of the liquid storage box 461, the upper surface of the squeezing element 466 has an arc-shaped structure, the squeezing element 466 is located below the water-absorbing sponge 462, and the bottom end of the liquid storage box 461 is fixedly connected to the injection tube 467. The squeezing element 466, with this configuration, can squeeze the water-absorbing sponge 462 more evenly, so that the insect repellent liquid in the water-absorbing sponge 462 can fully evaporate, improving the insect repellent effect. The injection tube 467 facilitates the replenishment of insect repellent liquid in the liquid storage box 461 by the staff, ensuring that the insect repellent protection mechanism 46 can continue to function.

[0018] Work process: When installing or maintaining cables in the socket box, first open the protective cover assembly 3 on both sides of the base 1, pull the cover plate 31, and extend the telescopic end of the gas spring telescopic rod 5 to provide support for the cover plate 31 so that it can be opened smoothly. The pressure plate 36 on the top inner side of the cover plate 31 rotates with the cover plate 31. Because the pressure plate 36 is in rotational cooperation with the roller 47 in the automatic power-off protection assembly 4, the pressure plate 36 no longer applies pressure to the roller 47 after rotating. At this time, the adjusting end of the limit switch body 42 drives the connecting seat 43 to rotate and reset. The trigger rod 44, which is fixed to the inner side of the connecting seat 43 by bolts, is adjusted to a horizontal state. The trigger block 45 at the top of the rear end of the trigger rod 44 no longer applies pressure to one end of the sealing plate 464 in the insect repellent protection mechanism 46. After the pressure of the trigger block 45 disappears, the corrugated elastic element 465 on one side of the top of the sealing plate 464 causes the sealing plate 464 to rotate around the mounting shaft 463 and tilt towards the water-absorbing sponge 462. The squeezing element 466 on the other side of the top of the sealing plate 464 squeezes the water-absorbing sponge 462, accelerating the release of the insect repellent odor that has been injected into the liquid storage box 461 through the injection tube 467. The odor is released through the opening and closing of the sealing plate 464, reducing the accumulation of mosquitoes around the automatic power-off protection component 4 and avoiding affecting the normal rotation of the connecting seat 43. After the cover plate 31 is opened and the trigger rod 44 is horizontal, the automatic power-off protection component 4 completes the power-off, and personnel can safely carry out cable installation and maintenance. The auxiliary plate 34 of the protective cover component 3 can be opened and rotated. Its surface fixed groove 35 cooperates with the movable groove 32 on the outer wall of the cover plate 31, which facilitates the flexible arrangement of cables. The cable can be easily inserted into the interior of the electrical socket box body 2 through the wire hole 7 opened in the junction box with holes. After the operation is completed, the protective cover assembly 3 is closed. The cover plate 31 closes slowly with the assistance of the gas spring telescopic rod 5. The pressure plate 36 gradually applies pressure to the roller 47. The roller 47 drives the trigger rod 44 to rotate. The trigger rod 44 drives the limit switch body 42 to move through the connecting seat 43, restoring power. At the same time, the trigger block 45 applies pressure to one end of the sealing plate 464 again. The sealing plate 464 returns to its initial state and stops squeezing the water-absorbing sponge 462. At this time, the sealing plate 464 is in a horizontal closed state, reducing the emission of insect repellent odor and effectively improving the service life of the insect repellent protection mechanism 46.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
