Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example Please see Figures 1-4 This utility model provides a telescopic marine charging pile, including a charging pile host 10, a fixing frame 20, a front guide assembly 30 and a front telescopic protective assembly 40.

[0019] The front guide component 30 is supported by the fixed frame 20 and works in conjunction with the front telescopic protective component 40 to limit the charging wire in the charging pile host 10. The limit stretching method plays a certain protective role.

[0020] A base 110 is fixedly mounted on the bottom of the charging pile host 10. The front guide assembly 30 includes a rear guide cylinder 310, a lower pressure roller 330, and an upper pressure roller 360. A fixing frame 20 connects the rear guide cylinder 310 and the base 110. The rear guide cylinder 310 has a lower opening 320 and an upper opening 350 at its bottom and top, respectively. The lower pressure roller 330 is rotatably mounted inside the lower opening 320 and is fixedly connected to the rear guide cylinder 310 via a lower bracket 340. The upper pressure roller 360 is rotatably mounted inside the upper opening 350 and is connected to the rear guide cylinder 310 via an upper elastic connecting part 370. The front telescopic protective assembly 40 includes a front guide ring 410 and a side elastic connecting part 420. The side elastic connecting parts 420 are located on both sides of the front guide ring 410 and are connected to the front guide ring 410 and the rear guide cylinder 310. The rear guide cylinder 310 and the front guide ring 410 are coaxially arranged.

[0021] The charging cable in the charging pile main unit 10 passes through the rear guide cylinder 310 and the second guide port 430. The second guide port 430 is located at the front end of the rear guide cylinder 310. The charging cable passing through the rear guide cylinder 310 is clamped by the lower pressure wheel 330 and the upper pressure wheel 360. This design allows the charging cable along the rear guide cylinder 310 and the front guide ring 410 to be easily stretched or retracted. When the charging head at the end of the charging cable is charging the ship, even if the charging cable is pulled by the tension on both sides of the front guide ring 410, the charging cable will cause the front guide ring 410 to shift to a certain lateral position, so that the front guide ring 410 and the rear guide cylinder 310 can easily clamp the charging cable, preventing the ship from further pulling the charging cable, and providing good protection for the connection between the charging cable and the charging pile main unit 10.

[0022] In the above specific embodiment, the side elastic connection portion 420 includes a connecting frame 421 and a second buffer 422. One end of the second buffer 422 is connected to the outer wall of the rear guide cylinder 310, and both ends of the connecting frame 421 are respectively connected to the other end of the second buffer 422 and the outer wall of the front guide ring 410. When the front guide ring 410 is pulled and deviates by the charging cable, the second buffer 422 in the side elastic connection portion 420 is compressed to provide a buffering protection function, and at the same time, the deviated front guide ring 410 and the rear guide cylinder 310 clamp the charging cable.

[0023] Furthermore, both ends of the front guide ring 410 are provided with a second guide port 430 with an arc-shaped structure. The second guide port 430 reduces the friction between the charging cable and the front guide ring 410.

[0024] Specifically, the upper elastic connection 370 includes an upper bracket 371, a fixing plate 372, and a first buffer 373. The upper bracket 371 is rotatably mounted on the upper pressure roller 360. The fixing plate 372 is fixed to the top of the upper bracket 371. The first buffer 373 connects the rear guide cylinder 310 and the fixing plate 372. Both ends of the rear guide cylinder 310 are provided with arc-shaped first guide openings 380. The first guide openings 380 are provided to reduce the friction between the charging cable and the interior of the rear guide cylinder 310.

[0025] In the specific configuration, both the lower pressure roller 330 and the upper pressure roller 360 are provided with annular guide grooves 390 on the outer ring of the middle part. This configuration helps to reduce the friction between the lower pressure roller 330, the upper pressure roller 360 and the charging cable, and at the same time plays a certain guiding role.

[0026] Furthermore, the fixing frame 20 includes a support 210 and a column 220. The bottom end of the support 210 is fixedly connected to the column 220, and the top end of the support 210 is fixedly connected to the rear guide cylinder 310. Mounting holes are provided on both the column 220 and the base 110.

[0027] It should be noted that the specific model and specifications of the charging pile host 10 need to be determined based on the actual specifications of the device. The specific selection and calculation method adopts existing technology in this field, and therefore will not be described in detail. The power supply and principle of the charging pile host 10 are clear to those skilled in the art, and will not be described in detail here.

[0028] The working principle of this retractable marine charging pile is as follows: During use, the charging cable in the charging pile main unit 10 passes through the rear guide cylinder 310 and the second guide port 430. The second guide port 430 is located at the front end of the rear guide cylinder 310. The charging cable passing through the rear guide cylinder 310 is clamped by the lower pressure wheel 330 and the upper pressure wheel 360. This design allows the charging cable along the rear guide cylinder 310 and the front guide ring 410 to be easily stretched or retracted. When the charging head at the end of the charging cable is charging the ship, even if the charging cable is pulled by the pulling force on both sides of the front guide ring 410, the charging cable will cause the front guide ring 410 to shift to a certain lateral position, so that the front guide ring 410 and the rear guide cylinder 310 can easily clamp the charging cable, preventing the ship from further pulling the charging cable, and providing good protection for the connection between the charging cable and the charging pile main unit 10.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
