Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a new energy charging pile that is easy to maintain. Background Technology

[0002] As a multidisciplinary field integrating power electronics, intelligent control, communication protocols and energy management, the technology and application of charging piles are constantly evolving.

[0003] With technological advancements, electric boats are becoming increasingly popular due to their advantages such as being pollution-free, having a simple structure, and being reasonably priced. As a result, shore-based charging stations have become essential charging facilities. However, in actual charging processes, boats need to be manually positioned so that the disembarkation area is close to the charging station in order to access the charging gun. This requires a certain level of skill in docking. In addition, to prevent collisions with the shore and to allow for turning space, boats often maintain a certain distance from the shore after docking. This necessitates personnel jumping ashore to retrieve the charging gun and then returning to the boat to reconnect it for charging, which poses a safety risk. Furthermore, charging cables are prone to scraping against the shore or even getting wet during the pulling process, causing wear or damage.

[0004] In summary, this application proposes a new energy charging pile that is easy to maintain, thereby improving the technical problems mentioned above. Summary of the Invention

[0005] To overcome the safety risks associated with the process of charging ships, which requires personnel to jump ashore to retrieve the charging gun and then return to the ship to reconnect it, and the drawbacks of the charging cable being easily scratched by the shore or even submerged in water during the pulling process, causing wear or damage, this invention provides a new energy charging pile that is easy to maintain.

[0006] The technical solution is as follows: a new energy charging pile that is easy to maintain, including a charging pile body; the charging pile body is equipped with a display screen; it also includes a mounting rod; the charging pile body is fixedly connected to two multi-stage electric push rods; the telescopic parts of the two multi-stage electric push rods are jointly fixedly connected to a mounting rod; the charging pile body is connected to a cable; the end of the cable is connected to a charging gun; the mounting rod is fixedly connected to a plug plate for inserting the charging gun; the mounting rod is connected to several fixed pulleys; the mounting rod has several through holes, and each through hole is slidably connected to a movable rod; the upper ends of all movable rods are jointly fixedly connected to a pull rod; each movable rod is fixedly connected to a rotating shaft, and each rotating shaft is rotatably connected to a movable pulley, with the cable wound in a W shape between the fixed pulleys and the movable pulleys.

[0007] Furthermore, the movable rod and the mounting rod are connected by a damped sliding connection.

[0008] Furthermore, it also includes a first limiting plate and a second limiting plate; the mounting rod is connected to the first limiting plate located on the upper side of the fixed pulley; all the movable rod shafts are jointly fixed to a second limiting plate located on the lower side of the movable pulley.

[0009] Furthermore, it also includes push plate one, push plate two, and elastic elements; several elastic elements are fixedly connected to the mounting rod; each elastic element's telescopic part is fixedly connected to a rotating shaft, and a fixed pulley is rotatably connected to the rotating shaft; limiting plate one is fixedly connected to all rotating shafts; the movable rod is configured as an elastic telescopic rod; several push plates one are fixedly connected to the upper side of the mounting rod, the ends of push plates one are configured as wedge-shaped surfaces, and push plates one corresponds to limiting plate one; several push plates two are fixedly connected to the lower side of the mounting rod, the ends of push plates two are configured as wedge-shaped surfaces, and push plates two correspond to limiting plate two.

[0010] Furthermore, it also includes a retaining collar; the mounting rod is fixed to the retaining collar, and the cable passes through the retaining collar.

[0011] Furthermore, it also includes a sliding sleeve; a sliding rod is fixedly connected to the charging pile body, the sliding rod is slidably connected to the sliding sleeve, and the cable passes through the sliding sleeve; a spring is fixedly connected to the sliding sleeve, and the spring is fixedly connected to the charging pile body; a guide ring is fixedly connected to the charging pile body; a traction rope is fixedly connected to the sliding sleeve, and the traction rope passes through the guide ring and is fixedly connected to the installation rod.

[0012] Furthermore, a silicone inner sleeve is provided on the inner side of the sliding sleeve.

[0013] Furthermore, it also includes a limiting sleeve; the charging pile body is fixedly connected to the limiting sleeve, and the cable passes through the limiting sleeve.

[0014] Furthermore, the sleeve rotation connection is reinforced with several retaining rings.

[0015] Furthermore, a sponge pad is provided on the inner side of the limiting sleeve.

[0016] The beneficial effects are as follows: By manually controlling the extension of the installation rod on the ship, the ship can be charged without going ashore, which effectively avoids the need for personnel to go back and forth to and from the shore, reduces safety risks, and effectively improves overall convenience. Furthermore, by pushing and pulling the movable rod and movable pulley, the cable can be quickly released and stored, preventing the cable from being easily scraped against the shore or even submerged in water when it is pulled out or retracted, thus preventing wear or damage.

[0017] By using limiting plates one and two to drive the fixed pulley and movable pulley to move in opposite directions, the elastic element and movable rod contract, causing the wound cable to change from a taut state to a slack state. This prevents the cable from being wound up in a taut state for a long time, which can easily lead to deformation and cracking, reducing the overall service life. Furthermore, by using limiting plates one and two to push the cable section located on the fixed pulley or movable pulley, the cable section is flattened, increasing the cable bending angle and improving the cable's protection.

Figures 1-6 As shown, it includes a charging pile body 1; the charging pile body 1 is equipped with a display screen 1001; It also includes an installation rod 2, a multi-stage electric push rod 21, a cable 3, a charging gun 4, a plug-in plate 5, a fixed pulley 6, a movable rod 7, and a movable pulley 8; the charging pile body 1 is fixedly connected to two multi-stage electric push rods 21; the telescopic parts of the two multi-stage electric push rods 21 are jointly fixedly connected to an installation rod 2; the charging pile body 1 is connected to a cable 3; the end of the cable 3 is connected to a charging gun 4; the installation rod 2 is fixedly connected to a plug-in plate 5, and the plug-in plate 5 is plugged into the charging gun 4; several fixed pulleys 6 are connected to the upper side of the installation rod 2; the installation rod 2 has several through holes, and a movable rod 7 is slidably connected to each through hole; a pull rod 71 is jointly fixedly connected to the upper end of all the movable rods 7; a rotating shaft is fixedly connected to the lower end of each movable rod 7, and a movable pulley 8 is rotatably connected to each rotating shaft, and the cable 3 is wound in a W shape between the fixed pulley 6 and the movable pulley 8.

[0022] The movable rod 7 is connected to the mounting rod 2 by a damped sliding connection. After the movable rod 7 is manually pulled, it can remain stable under the action of friction, preventing the cable 3 from being pulled during charging and affecting the normal charging of the ship.

[0023] It also includes a first limiting plate 101 and a second limiting plate 102; the mounting rod 2 is connected to the first limiting plate 101, and the first limiting plate 101 is located on the upper side of the fixed pulley 6; all the movable rods 7 are fixedly connected to a second limiting plate 102, and the second limiting plate 102 is located on the lower side of the movable pulley 8.

[0024] It also includes a push plate 111, a push plate 112, and an elastic element 113; the mounting rod 2 is fixedly connected to several elastic elements 113, which are configured as elastic telescopic rods; each elastic element 113 has a rotating shaft fixedly connected to its telescopic part, and the fixed pulley 6 is rotatably connected to the rotating shaft, and the limiting plate 101 is fixedly connected to all the rotating shafts; the movable rod 7 is configured as an elastic telescopic rod; several push plates 111 are fixedly connected to the upper side of the mounting rod 2, the ends of push plates 111 are configured as wedge-shaped surfaces, and push plates 111 correspond to limiting plates 101; several push plates 212 are fixedly connected to the lower side of the mounting rod 2, the ends of push plates 212 are configured as wedge-shaped surfaces, and push plates 212 correspond to limiting plates 2102.

[0025] It also includes a fixing collar 114; the mounting rod 2 is fixedly connected to the fixing collar 114, and the cable 3 passes through the fixing collar 114. The cable 3 is fixed by the fixing collar 114. The part of the cable 3 located on the left side of the fixing collar 114 is used for manual pulling out for charging, and the part of the cable 3 located on the right side is used for moving the mounting rod 2 to pull out.

[0026] It also includes a sliding sleeve 201, a spring 202, a traction rope 203, and a guide ring 204; the charging pile body 1 is fixedly connected to a sliding rod, the sliding rod is slidably connected to the sliding sleeve 201, and the cable 3 passes through the sliding sleeve 201; the sliding sleeve 201 is fixedly connected to the spring 202, and the spring 202 is fixedly connected to the charging pile body 1; the charging pile body 1 is fixedly connected to the guide ring 204; the sliding sleeve 201 is fixedly connected to the traction rope 203, and the traction rope 203 passes through the guide ring 204 and is fixedly connected to the mounting rod 2.

[0027] The inner side of the sliding sleeve 201 is provided with a silicone inner sleeve to protect the cable 3 that passes through it.

[0028] by Figure 1Taking a perspective example, the charging pile body 1 is installed on the foundation 100, with water in front of the foundation 100. The display screen 1001 of the charging pile body 1 displays a QR code. When a ship needs charging, it is manually moored in front of the foundation 100, maintaining a distance of 50cm-100cm. Then, the operator uses a mobile phone on the ship to scan the QR code on the display screen 1001, which redirects to the mini-program of the charging pile body 1. The mini-program controls the multi-stage electric push rod 21 to move the mounting rod 2, the plug-in plate 5, and other connected parts forward until the mounting rod 2 moves above the ship. Then, the operator removes the charging gun 4 plugged into the plug-in plate 5 and pulls the pull rod 71, which moves the movable rod 7 and the movable pulley 8 upward, releasing the cable 3 between the fixed pulley 6 and the movable pulley 8. This allows for manual movement of the charging gun 4 to the ship's charging area for charging. After charging is complete, the operator first pushes the pull rod 71, movable rod 7, and movable pulley 8 downwards. The movable pulley 8 then rewinds the pulled-out cable 3 between the fixed pulley 6 and the movable pulley 8. The charging gun 4 is then inserted back onto the plug plate 5, and the installation rod 2 is moved back to its original position via a mini-program. In this way, by manually controlling the extension of the installation rod 2 on the ship, the operator can charge the ship without going ashore, effectively avoiding the need for personnel to repeatedly go ashore and back, reducing safety risks, and significantly improving overall convenience. By pushing and pulling the movable rod 7 and movable pulley 8, the cable 3 can be quickly released and retracted, preventing it from scraping against the shore or getting wet when pulled out or retracted, thus preventing wear or damage.

[0029] When cable 3 is wound between fixed pulley 6 and movable pulley 8, the cable 3 is restricted by the limiting plate 101 on the upper side of fixed pulley 6 and the limiting plate 202 on the lower side of movable pulley 8 to prevent cable 3 from shifting during the pulling out and retraction process, which would affect subsequent use; and the cable 3 is pulled up and released by the limiting plate 202 and movable pulley 8, so that the user can pull out cable 3 for charging; at the same time, movable rod 7 is connected to mounting rod 2 by damping sliding. After movable rod 7 is pushed or pulled, it can remain stable under the action of friction, preventing the cable 3 from being pulled during charging, which would affect the normal charging of the ship, and maintaining stability when not in use.

[0030] Considering that after charging, the cable 3 is retracted back between the fixed pulley 6 and the movable pulley 8 by moving the movable rod 7, the cable 3 is retracted in a taut state. Over time, this can easily lead to deformation and cracking of the cable 3, reducing its service life. Furthermore, the cable 3 passes over the fixed pulley 6 or the movable pulley 8 at a narrow, acute angle, making the portion of the cable 3 on the fixed pulley 6 or the movable pulley 8 more prone to deformation and cracking. Therefore, after charging is complete and the cable 3 is manually retracted between the fixed pulley 6 and the movable pulley 8, the mounting rod 2 is moved back to its original position. During the resetting process, when the first limiting plate 101 and the second limiting plate 102 contact the first pushing plate 111 and the second pushing plate 112 respectively, as the mounting rod 2 continues to reset, the cable 3 is moved back to its original position by moving the mounting rod 2. Under the action of the wedge-shaped surface at the end of push plate 111 and push plate 112, push plate 111 and push plate 112 push the limiting plate 101 and limiting plate 102 to move towards each other. The limiting plate 101 and limiting plate 102 respectively drive the fixed pulley 6 and the movable pulley 8 to move towards each other. The elastic element 113 and the movable rod 7 contract, so that the wound cable 3 changes from a taut state to a slack state, thereby avoiding the cable 3 from being pulled up in a taut state for a long time, which is prone to deformation and cracking, reducing the overall service life. And by pushing the cable 3 located on the fixed pulley 6 or the movable pulley 8 through the opposing limiting plate 101 and limiting plate 102, the part of the cable 3 is flattened, increasing the bending angle of the cable 3 and improving the protection of the cable 3.

[0031] Furthermore, cable 3 is fixed by the fixing collar 114 on the mounting rod 2, dividing cable 3 into two sections. During the forward movement of the mounting rod 2, the mounting rod 2 pulls the traction rope 203, which pulls the sliding sleeve 201 to move upward along the slide bar on the charging pile body 1. The spring 202 contracts, and the sliding sleeve 201 drives the cable 3 section on the right side of the fixing collar 114 to move upward, so that the mounting rod 2 can drive the cable 3 section on the left side of the fixing collar 114 to move forward. After charging is completed, when the mounting rod 2 resets, it stops pulling the traction rope 203, the spring 202 rebounds and resets, and drives the sliding sleeve 201 to move downward and reset. The sliding sleeve 201 moves the cable 3 section on the right side of the fixing collar 114 downward again. At this time, the sliding sleeve 201 restricts the cable 3 section to prevent it from twisting or shifting during the reset process, or even scraping against the charging pile body 1, causing wear on the cable 3.

[0032] Example 2: Based on Example 1, referring to... Figures 1-6 As shown, it also includes a limiting sleeve 205; the charging pile body 1 is bolted to the limiting sleeve 205, and the cable 3 passes through the limiting sleeve 205. The limiting sleeve 205 restricts and fixes the connection between the cable 3 and the charging pile body 1, preventing the cable 3 from being reset during the movement and reset of the mounting rod 2, which would cause the connection between the cable 3 and the charging pile body 1 to be twisted, resulting in the cable 3 and the charging pile body 1 becoming loose.

[0033] The sleeve 205 is connected to several retaining rings 20501, which restrict and fix the connection between the cable 3 and the charging pile body 1. During subsequent maintenance, the retaining rings 20501 can be rotated to release the fixation, thus facilitating maintenance.

[0034] A sponge pad is provided on the inner side of the limiting sleeve 205 to protect the cable 3 when it is fixed.

[0035] Based on the above embodiment 1, when the installation rod 2 moves, it will pull the cable 3 segment on the right side of the fixing sleeve 114 to move together. The movement of the cable 3 can easily cause pulling on the connection between the cable 3 and the charging pile body 1, resulting in loosening of the connection between the cable 3 and the charging pile body 1. Therefore, a limiting sleeve 205 is also provided. The limiting sleeve 205 restricts and fixes the connection between the cable 3 and the charging pile body 1, thereby avoiding pulling on the connection between the cable 3 and the charging pile body 1 when the cable 3 is moved, which would cause it to loosen. The limiting sleeve 205 and the sliding sleeve 201 cooperate with each other to restrict the cable 3 around the charging pile body 1, preventing the cable 3 from protruding outward and affecting the surrounding personnel. When the cable 3 is replaced or maintained in the future, the fixing of the cable 3 can be released by rotating the retaining ring 20501 of the limiting sleeve 205 to connect the hole, so as to facilitate manual maintenance of the cable 3.

[0036] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
