The construction of supporting charging infrastructure is also proceeding rapidly. Charging stations are ubiquitous, found in bustling city streets, shopping mall parking lots, newly built residential areas, and industrial parks. As the primary link between the charging station and the power source, the precision and safety of the charging cable's installation directly impact the efficient and stable operation of the entire charging system. This has created an urgent need for precise positioning devices embedded in the charging cables.

[0003] Common charging cable positioning devices mostly rely on electromagnetic induction or ultrasonic detection. Electromagnetic induction devices determine the location of the charging cable by emitting electromagnetic signals of a specific frequency and observing changes in the magnetic field around it; ultrasonic detection utilizes the propagation characteristics of ultrasonic waves in different media, calculating the orientation information of the charging cable by emitting and receiving ultrasonic pulses.

[0004] In existing technologies, some automatic marking devices use a simple mechanical stamping method, which not only makes it difficult to accurately control the marking depth, but also easily damages other underground pipelines. Therefore, a precise positioning device for embedding charging cables is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a precise positioning device for embedding charging cables, which aims to improve the problem that some existing devices cannot automatically mark the location.

[0009] As a further description of the above technical solution: the buffer assembly includes a buffer spring, the buffer spring is sleeved on the outside of the marker post, and the upper and lower ends of the buffer spring are fixed to the outside of the marker post and the inside of the slide bar;

[0010] As a further description of the above technical solution: the outer side of the marking post is slidably connected to the inner side of the bottom of the slide bar;

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the cylinder pushes the column to slide smoothly along the slide bar, which drives the roller, the fixing plate and the marking column to move down synchronously, thereby realizing the accurate marking of the charging cable position. This automated method ensures the uniformity and repeatability of the marking action and improves the accuracy of the marking. At the same time, it also effectively avoids the errors and deviations that may occur in the manual marking process, and improves the overall work efficiency and quality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] Reference Figures 1 to 3 An embodiment of this utility model provides a charging cable embedding precision positioning device, including a main body 1. The main body 1 carries key components such as a display component and a detection mechanism. A display component for display is fixedly connected to the top of the main body 1, and a detection mechanism is provided at the bottom of the main body 1. A connecting ring 11 is fixedly connected to the outside of the detection mechanism, and a marking positioning mechanism is provided outside the connecting ring 11. The connecting ring 11 is used to connect the positioning mechanism and the detection mechanism.

[0025] The marking and positioning mechanism includes two protective shells 7, which resist external interference and damage. The two protective shells 7 are fixedly connected to both sides of the connecting ring 11. The inside of the protective shell 7 is fixedly connected to a slide bar 17. The outside of the slide bar 17 is slidably connected to a pushing component, which provides a smooth sliding track for the pushing component and guides the pushing component to move accurately along a predetermined trajectory. The outside of the pushing component is rotatably connected to a roller 14. A protruding shaft is provided in the middle of the roller 14. The roller 14 is used to accurately transmit power to the marking post 12. The outside of the protruding shaft of the roller 14 is rotatably connected to two fixing plates 15, which are used to support the rotation of the roller 14. The bottom of the fixing plate 15 is fixedly connected to the marking post 12. The marking post 12 leaves a lasting mark on the location of the underground charging line with a clear mark, which is convenient for subsequent construction and maintenance. The outside of the marking post 12 is provided with a buffer component.

[0026] The pushing assembly includes a pushing column 13, the top of which is provided with a sliding groove. The top sliding groove of the pushing column 13 is slidably connected to the outside of the slide bar 17. The pushing column 13 moves stably along the slide bar 17 under the drive of the cylinder 8. The cylinder 8 is fixedly connected inside the protective shell 7. The cylinder 8 pushes the pushing column 13. The driving end of the cylinder 8 is fixedly connected to the outside of the pushing column 13. The buffer assembly includes a buffer spring 16, which is sleeved on the outside of the marking column 12. The upper and lower ends of the buffer spring 16 are fixed to the outside of the marking column 12 and the inside of the slide bar 17. The outside of the marking column 12 is slidably connected to the bottom inner side of the slide bar 17.

[0027] Reference Figure 1 , Figure 2 and Figure 4The detection mechanism includes a connecting column 5, which ensures stable transmission of the detection signal. The top of the connecting column 5 is fixedly connected to the bottom of the main body 1. An adjustment component for adjustment is fixedly connected to the bottom of the connecting column 5. A probe 10 is fixedly connected to the outside of the adjustment component. The adjustment component includes a telescopic rod 6, the top of which is fixedly connected to the bottom of the connecting column 5. A connecting block 9 is fixedly connected to the bottom of the telescopic rod 6. The connecting block 9 allows the probe 10 to rotate freely within a certain range, thereby capturing weak signals from the charging cable from multiple angles and improving detection accuracy. The probe 10, with its sensitive sensing performance, penetrates deep underground to accurately perceive the electromagnetic field around the charging cable. A shaft is set in the middle of the connecting block 9. The external rotation of the shaft inside the connecting block 9 is connected to the outside of the probe 10. The telescopic rod 6 can be adjusted according to the complexity of the underground environment and the pre-buried location of the charging cable. The device is designed to meet practical needs such as depth, allowing for flexible extension and retraction to change its length and precisely adjust the height of the probe 10. The display component includes a touchscreen 3, which provides a clear and intuitive visual interface to display key information such as the detected charging cable position and depth in real time, facilitating quick understanding of the situation by the operator. The bottom of the touchscreen 3 is fixedly connected to the top of the main body 1. A protective frame 2 is fixedly connected to the outside of the main body 1 to prevent damage to the main body 1 and the touchscreen 3 from external collisions, ensuring normal operation of the device. An indicator light 19 is fixedly connected to the outside of the touchscreen 3, as well as a rotating shaft 18. The rotating shaft 18 allows for flexible adjustment of the touchscreen 3's angle when the operator holds and rotates it using a rotating handle 4. The rotating handle 4 is rotatably connected inside the rotating shaft 18. The indicator light 19 illuminates when the charging cable position is detected.

[0028] Working principle: By gripping and rotating the handshake 4, the operator can easily adjust the display touchscreen 3 to a suitable viewing angle using the rotation function of the rotating shaft 18. The indicator light 19 on the outside of the display touchscreen 3 shows the correctness of the detection position. When the main body 1 is in motion, the display touchscreen 3 lights up. The protective frame 2 prevents the main body 1 from being damaged by collisions during use. The telescopic rod 6 below the connecting column 5 can be adjusted in length according to actual needs, thereby changing the height of the probe 10. The shaft inside the connecting block 9 allows the probe 10 to rotate, thus adjusting the detection angle of the probe 10.

[0029] Once the exact location of the charging cable is detected, the operator can issue a command via the touchscreen 3 to push the push column 13 through the cylinder 8 inside the protective casing 7. The groove on the top of the push column 13 slides outside the slide bar 17, causing the push column 13 to slide along the slide bar 17. As the push column 13 slides, it drives the roller 14 to move. During the movement of the roller 14, the protruding shaft in the middle drives the fixing plate 15, causing the marking column 12 below the fixing plate 15 to move downward. The marking column 12 is inserted into the ground to mark the location of the charging cable. During the insertion of the marking column 12, the buffer spring 16 reduces the impact force on the marking column 12 when it is inserted into the ground, preventing damage to the marking column 12 and making the marking process more stable.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
