Description

Technical Field

[0001] The utility model relates to the technical field of AC / DC integrated shore power piles, and more specifically, to an AC / DC integrated shore power pile. Background Art

[0002] In the existing AC / DC integrated shore power pile technology, cable connection is the key link for the shore power pile to provide power to the ship. However, since the cable needs to withstand long-term use and pulling, if there is no effective fixing measure, the cable may become virtual. Cable virtualization refers to the relative displacement between the internal wire and the insulation layer of the cable after being pulled for a long time, resulting in a decrease in the insulation performance of the cable, and even a short circuit or open circuit. This phenomenon will not only affect the normal power supply of the shore power pile, but may also damage the ship's power system and even cause safety accidents. Utility Model Content

A positioning groove 9 is provided in the top sleeve, and the positioning sleeve 5 is clamped in the positioning groove 9.

[0029] In this embodiment, when the cable needs to be fixed, the cable passes through the bottom sleeve 2 and the fixing sleeve 4, and then the hexagonal wrench is inserted into the hexagonal groove 17, and then the top pipe 7 is driven to rotate along the thread of the fixing sleeve 4. Since the positioning sleeve 5 is inserted into the positioning groove 9, the fixing sleeve 4 is in a fixed state, and then the top pipe 7 is driven to press against the multiple sliders 12, so that the multiple sliders 12 shrink along the shrink sleeve 11 toward the axial direction, so that the multiple top balls 15 press against the side wall of the cable, and the thrust is applied by the spring 13. Because the spring 13 ensures that the cable will not be in a rigidly fixed state when subjected to tension, thereby avoiding damage to the epidermis, thereby ensuring the stability of the fixation. When it needs to be released, the top pipe 7 is released, and the slider 12 is pushed up under the action of multiple return springs 16, thereby releasing the connection with the cable.

[0030] See also Figure 2 and Figure 3 As an implementation method of the synchronization mechanism: the synchronization mechanism includes a telescopic sleeve 18 and a guide strip 19, the telescopic sleeve 18 is slidably connected to the side walls of the rotating sleeve 8 and the fixed sleeve 4, a plurality of guide strips 19 are provided, and the plurality of guide strips 19 are respectively installed on the inner wall of the telescopic sleeve 18, a plurality of guide grooves 20 are equidistantly provided on the side walls of the rotating sleeve 8 and the fixed sleeve 4, the guide strip 19 is slidably connected in the guide groove 20, a push spring 21 is provided on the telescopic sleeve 18, and the push spring 21 is pressed against the connecting sleeve 3.

[0031] More specifically, when it is necessary to rotate the rotating sleeve 8, first push the telescopic sleeve 18 to compress the push spring 21, then release the clamping connection between the guide sleeve and the rotating sleeve 8, then complete the clamping connection of the cable, and then release the telescopic sleeve 18.

[0032] In summary, when the overall device is in use or running: when the cable needs to be fixed, the cable passes through the bottom sleeve 2 and the fixing sleeve 4, and then the hexagonal wrench is inserted into the hexagonal groove 17, and then the top pipe 7 is driven to rotate along the thread of the fixing sleeve 4. Since the positioning sleeve 5 is inserted into the positioning groove 9, the fixing sleeve 4 is in a fixed state, and then the top pipe 7 will be driven to press against multiple sliders 12, so that the multiple sliders 12 shrink along the shrink sleeve 11 toward the axial direction, so that multiple top balls 15 press against the side wall of the cable, and the thrust is applied by the spring 13. Because the spring 13 ensures that the cable will not be in a rigidly fixed state when subjected to tension, thereby avoiding damage to the epidermis, thereby ensuring the stability of the fixation, and when it needs to be released, the top pipe 7 will be released under the action of multiple return springs 16 to push the slider 12 up, thereby releasing the connection with the cable.

[0033] When it is necessary to rotate the rotating sleeve 8, first push the telescopic sleeve 18 to compress the push spring 21, then release the clamping connection between the guide sleeve and the rotating sleeve 8, then complete the clamping connection of the cable, and then loosen the telescopic sleeve 18.
