Description

Technical Field

[0001] This utility model relates to the field of charging pile monitoring technology, and in particular to a remote fault diagnosis device for shared charging piles based on the Internet of Things. Background Technology

[0002] As an important energy replenishment device for electric vehicles, the operating status of charging stations directly affects the efficiency and safety of electric vehicles. Currently, Chinese patent CN222798563U discloses a mounting bracket, the bottom of which is connected to an adjustment bracket via a drive component one. Inside the adjustment bracket, a camera is connected via a drive component two. The camera contains a video processing module, a data processing module, and a communication module. The existing technical solutions have the following drawbacks: the adjustment angle of the adjustment bracket is limited, and there is no cleaning module. When the camera is dusty, it cannot be cleaned, and when the device is damaged, disassembly is inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a remote fault diagnosis device for shared charging piles based on the Internet of Things, so as to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A remote fault diagnosis device for shared charging stations based on the Internet of Things includes: A clamping module, wherein multiple clamping modules are provided and the multiple clamping modules are symmetrically fixedly installed on the wall; A moving module is located between clamping modules, and its left and right ends are fixedly installed with the clamping modules respectively. The module includes a housing, which is fixedly installed at the bottom of the mobile module. A cleaning module is fixedly installed on the left side of the housing, and a diagnostic module is fixedly installed inside the housing.

[0005] By adopting the above technical solutions, multiple symmetrical clamping modules can provide balanced clamping force from both sides of the wall, facilitating disassembly; the moving module connects the clamping module and the housing, allowing the housing to flexibly adjust its position and angle, overcoming the limitation of traditional adjustment brackets that can only be adjusted within a small range; the housing not only protects the internal diagnostic module from wind, rain, and dust, but its detachable connection with the moving module also facilitates later maintenance, allowing for inspection of internal components simply by removing the housing; while the cleaning module on the left side specifically addresses the problem of traditional cameras easily accumulating dust and being unable to clean themselves, ensuring the accuracy of signal acquisition during fault diagnosis.

[0006] In a further embodiment, the clamping module includes a base plate, a first mounting plate, a first round rod, an eccentric wheel, a second round rod, and pressure blocks. The base plate is fixedly mounted on a wall. The first mounting plate is symmetrically fixedly mounted on the bottom of the base plate. The two ends of the first round rod are rotatably mounted on the first mounting plate. The axis of the first round rod is arranged in the front-rear direction. The two ends of the first round rod extend through the first mounting plate to the opposite sides of the first mounting plate. The eccentric wheel is fixedly mounted on both ends of the first round rod. The second round rod is symmetrically and movably mounted on the top of the base plate. The bottom end of the second round rod extends through the base plate to the eccentric wheel. Pressure blocks are movably mounted on the top of each of the second round rods. A bracket is symmetrically and fixedly mounted on the top of the base plate. The middle section of the pressure block is movably mounted on the bracket. A handle is fixedly mounted on the middle section of the first round rod.

[0007] By adopting the above technical solution, during installation, the base plate is first fixed to the wall. The symmetrical first mounting plate can stably support the first round rod, preventing it from shaking during rotation. Turning the handle will drive the first round rod and the eccentric wheels at both ends to rotate synchronously. When the eccentric wheels rotate, they will push the second round rod upward. The top of the second round rod pushes the pressure block to rotate around the bracket. The pressure block forms a lever structure with the bracket as the fulcrum. With just a slight turn of the handle, the other end of the pressure block can be pressed tightly against the mounting frame of the moving module, realizing the quick fixation of the device. When disassembling, turn the handle in the opposite direction. The eccentric wheels will reset, and the pressure block will naturally loosen after losing its upward force. Without the need for complicated tools, the hassle of unscrewing the fixing bolts one by one during the disassembly of traditional devices is completely solved, greatly improving maintenance efficiency.

[0008] In a further embodiment, the moving module includes a mounting frame, a first motor, a second motor, a third motor, a first fixing plate, a second fixing plate, a third fixing plate, and a fourth fixing plate. The left and right ends of the mounting frame are located between the pressure block and the base plate. The first motor is fixedly mounted on the bottom of the mounting frame, and the shaft of the first motor is fixedly mounted on the first fixing plate. The second fixing plate is fixedly mounted on the bottom right end of the first fixing plate. The second motor is fixedly mounted on the bottom right end of the second fixing plate, and the shaft of the second motor extends through the second fixing plate to the left side of the second fixing plate. The third fixing plate is fixedly mounted on the shaft of the second motor. The fourth fixing plate is fixedly mounted on the front left end of the third fixing plate. The third motor is fixedly mounted on the front side of the fourth fixing plate, and the shaft of the third motor extends through the fourth fixing plate to the rear side of the fourth fixing plate. The shaft of the third motor is fixedly mounted on a fixing frame, and the outer shell is fixedly mounted on the top of the fixing frame.

[0009] By adopting the above technical solution, after the mounting bracket is fixed by the clamping module, multi-angle adjustment can be achieved through the cooperation of three motors: the first motor drives the first fixing plate to rotate, which can adjust the angle of the shell in the front and back direction, making it convenient to monitor the components on the front or side of the charging pile; the second motor is mounted on the second fixing plate, and when its shaft drives the third fixing plate to rotate, it can change the angle of the shell in the left and right direction, avoiding blind spots caused by the charging pile structure; the third motor is fixed by the fourth fixing plate, and after starting, it drives the fixing bracket and the shell to finely adjust the pitch angle, ensuring that the diagnostic module can accurately align with the charging pile's connectors, indicator lights and other key parts.

[0010] In a further embodiment, the diagnostic module includes a temperature sensor, a vision sensor, a data acquisition module, and a communication module. The temperature sensor, vision sensor, data acquisition module, and communication module are all fixedly installed on the inner bottom of the housing. An clearance hole is provided on the left side of the housing, and a transparent plate is fixedly installed in the clearance hole.

[0011] By adopting the above technical solutions, the temperature sensor can collect temperature data of the internal circuits and charging modules of the charging pile in real time. Once the temperature exceeds the preset safety threshold, it can immediately trigger an alarm. The vision sensor collects images through the avoidance hole on the left side of the shell. The transparent plate can prevent rain and dust from directly contacting the sensor lens without affecting the image clarity. It can clearly capture whether the charging pile is damaged or whether the charging gun is in place. The data acquisition module integrates and processes the temperature data and image information, and then transmits it to the remote monitoring platform through the communication module. Staff can view the status of the charging pile in real time in the background and realize remote fault diagnosis.

[0012] In a further embodiment, the cleaning module includes a fourth motor, a ball screw, a slide rail, a slider, and a brush. The fourth motor is fixedly installed on the left side of the housing. One end of the ball screw is fixedly installed to the shaft of the fourth motor. The slider is rotatably installed on the other end of the ball screw. The slide rail is fixedly installed on the left side of the housing and is located at the bottom of the clearance hole. One end of the brush is fixedly installed on the bottom of the slider, and the other end of the brush is slidably installed on the slide rail.

[0013] By adopting the above technical solution, when the image clarity acquired by the vision sensor decreases, such as when dust accumulates on the transparent plate, the fourth motor starts, driving the ball screw to rotate, and the slider moves along the screw axis; at the same time, one end of the brush moves with the slider, and the other end slides on the slide rail. The slide rail can limit the movement trajectory of the brush and prevent scratching the transparent plate; the brush can quickly remove dust from the surface of the transparent plate during the movement, eliminating the need for manual climbing for cleaning, solving the problem of decreased monitoring accuracy caused by dust accumulation on the lens in traditional devices, and ensuring long-term stable operation of the diagnostic module.

[0014] In a further embodiment, mounting holes are provided at the adjacent ends of the first mounting plate, and a pin is inserted into the mounting hole to prevent the handle from rotating accidentally.

[0015] By adopting the above technical solution, when the handle is rotated to the position where the pressure block fully presses against the mounting bracket, the pin is inserted into the mounting hole of the first mounting plate. The pin can block the side of the handle to prevent the handle from rotating accidentally due to outdoor wind, vehicle collision or accidental contact by personnel. If the handle is loose, it will cause the mounting bracket to shift, affecting the monitoring angle, or even causing the device to fall off. The design of the pin can effectively avoid such risks and ensure that the clamping module maintains a stable fixing effect for a long time.

[0016] In summary, this utility model has the following beneficial effects: 1. When the handle is rotated to the position where the pressure block fully presses against the mounting bracket, the pin is inserted into the mounting hole of the first mounting plate. The pin can block the side of the handle to prevent the handle from turning accidentally due to outdoor wind, vehicle collision or accidental contact by personnel. If the handle is loose, it will cause the mounting bracket to shift, affecting the monitoring angle, or even causing the device to fall off. The design of the pin can effectively avoid such risks and ensure that the clamping module maintains a stable fixing effect for a long time. Attached Figure Description

[0024] The diagnostic module 5 includes a temperature sensor, a vision sensor, a data acquisition module, and a communication module. The temperature sensor, vision sensor, data acquisition module, and communication module are all fixedly installed at the bottom inner end of the housing 3. An clearance hole is provided on the left side of the housing 3, and a transparent plate is fixedly installed inside the clearance hole.

[0025] The cleaning module 4 includes a fourth motor 41, a ball screw 42, a slide rail 43, a slider 44, and a brush 45. The fourth motor 41 is fixedly installed on the left side of the housing 3. One end of the ball screw 42 is fixedly installed on the shaft of the fourth motor 41. The slider 44 is rotatably installed on the other end of the ball screw 42. The slide rail 43 is fixedly installed on the left side of the housing 3 and is located at the bottom of the clearance hole. One end of the brush 45 is fixedly installed on the bottom of the slider 44, and the other end of the brush 45 is slidably installed on the slide rail 43. Mounting holes are provided at the adjacent ends of the first mounting plate 12. A pin 7 passes through the mounting hole and is used to prevent the handle from rotating accidentally.

[0026] The specific implementation process is as follows: First, fix the base plate 11 of the clamping module 1 to the wall next to the charging pile. The first mounting plate 12, which is symmetrical front and back, firmly supports the first round rod 13. Then, turn the handle to drive the first round rod 13 and the eccentric wheels 14 at both ends to rotate. The eccentric wheels 14 push the second round rod 15 upward. The second round rod 15 pushes the pressure block 16 to rotate around the bracket 6. This lever structure saves effort. With a gentle turn of the handle, the pressure block 16 can press the mounting bracket 21 of the moving module 2 tightly. Finally, insert the pin 7 into the mounting hole of the first mounting plate 12 to prevent the handle from coming loose due to strong winds or accidental collisions. The entire installation does not require complicated tools and can be completed in ten minutes.

[0027] After installation, first adjust the angle of the moving module 2: Start the first motor 22 to rotate the first fixing plate 25, adjusting the outer shell 3 to a position that covers the front or side of the charging pile; then turn on the second motor 23 to rotate the third fixing plate 27 to adjust its left and right angles, avoiding obstruction by the charging pile outer shell 3; finally, use the third motor 24 to fine-tune the pitch angle of the fixing frame until the diagnostic module 5 inside the outer shell 3 is aligned with the charging connector, indicator lights, and line interfaces of the charging pile, ensuring no blind spots in monitoring. The temperature sensor monitors the temperature of the internal circuitry and charging module of the charging pile in real time, triggering an alarm signal if the temperature exceeds the safe value; the vision sensor takes pictures of the appearance and operating status of the charging pile through the transparent plate on the left side of the outer shell 3, such as whether the charging gun is back in place and whether the outer shell 3 is damaged. These images and temperature data are integrated by the data acquisition module and then transmitted to the remote monitoring platform through the communication module. Staff can check the status of each charging pile at any time in the background without having to conduct daily on-site inspections.

[0028] If the backend detects that the image transmitted by the visual sensor has become blurry, it remotely starts the cleaning module 4. The fourth motor 41 starts to turn, which drives the ball screw 42 to turn. The slider 44 moves along the screw, and one end of the brush 45 moves with the slider 44, while the other end slides on the slide rail 43 to clean the dust on the transparent plate.

[0029] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0030] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
