[0043] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0044] As described in the background section, the mainstream monitoring method in the existing technology is to fix the monitoring unit at the cable connection end, such as the joint or terminal. This monitoring method is essentially a point monitoring, which can only obtain the status information of local key points of the cable (such as local temperature and partial discharge).

[0045] For the cable body, which accounts for the majority of the line length, potential issues such as insulation aging, localized damage, and external force damage create monitoring blind spots.

[0046] Furthermore, because the connection points (joints, terminations) are the most structurally complex, have the most concentrated electric fields, and are most dependent on manufacturing processes in a cable line, their failure modes (such as poor contact and sealing failure) differ significantly from the typical failure modes of the cable itself (such as insulation water treeing, mechanical damage, and sheath breakage). Monitoring only the connection points cannot reflect the general aging degree of the insulation or randomly distributed external damage. Local temperature or partial discharge signals are only indirect and localized representations of the cable system's health status. A section of a cable may have serious insulation defects, but as long as these defects do not affect the electrical parameters at the distant connection points, they cannot be detected by the "point monitoring" system.

[0047] This results in an inability to achieve a comprehensive and continuous assessment of the health status of the entire cable line, leading to low monitoring efficiency and insufficient preventative maintenance capabilities.

[0048] In view of this, this application provides a cable monitoring device. The monitoring element can move circumferentially along the mounting frame, allowing it to scan every angular position of the cable circumference. Combined with the axial movement driven by the moving component, this device can perform axial and circumferential coverage scanning of the cable's outer surface, achieving comprehensive inspection and monitoring of the entire distribution cable's outer surface condition, completely eliminating blind spots from fixed-point monitoring. By designing the monitoring component as a circumferential mounting frame and placing it on the moving component, a stable and compact integrated platform is formed. This eliminates the need for a separate, large support structure for each function, helping to control the overall device's size and weight while ensuring functionality. Through the combination of mobile inspection and circumferential scanning, this device can efficiently complete comprehensive inspection of long-distance cables, providing extremely rich and accurate data for cable condition assessment, hazard location, and lifespan prediction.

[0049] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0050] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0051] refer to Figure 1 This application provides a cable monitoring device, including a moving component 100 and a monitoring component 200.

[0052] The movable component 100 is fitted onto the outside of the cable and is used to move relative to the cable.

[0053] The monitoring component 200 includes a mounting frame 210 and a monitoring element 220. The mounting frame 210 is disposed on the movable component 100 and is used to surround the outside of the cable.

[0054] The monitoring element 220 is movable relative to the moving assembly 100 along the circumference of the mounting frame 210, and the monitoring element 220 is used at least to obtain the current status of the cable.

[0055] It is understood that the core function of the moving component 100 is to provide the ability to move along the cable. The moving component 100 does not straddle the cable in a point or line contact manner, but rather surrounds the cable with a ring-shaped structure. This structure increases the contact area with the cable, provides a more stable constraint, and prevents slippage on the cable in the cable monitoring device.

[0056] The monitoring component 200 performs status detection.

[0057] Mounting frame 210 is used to surround the outside of the cable, indicating that mounting frame 210 itself is also a frame structure that surrounds the cable, which provides a stable, cable-surrounding mounting reference for monitoring.

[0058] The monitoring element 220 is not fixed to the mounting frame 210 and can move independently in the circumferential direction around the cable. This enables it to achieve a dynamic scanning capability. That is, while the entire device moves along the axial direction of the cable (driven by the moving component 100), the monitoring element 220 can also move along the circumferential direction of the cable, so that the monitoring element 220 can acquire status information (such as temperature, image, partial discharge signal, etc.) at different positions on the outer surface of the cable in the circumferential direction.

[0059] In this way, the monitoring element 220 can move circumferentially along the mounting frame 210, allowing it to scan every angular position of the cable circumference. Combined with the axial movement driven by the moving component 100, this device can perform axial and circumferential coverage scanning of the cable's outer surface, achieving comprehensive inspection and monitoring of the entire distribution cable's outer surface condition, completely eliminating blind spots from fixed-point monitoring. By designing the monitoring component 200 as a circumferential mounting frame 210 and placing it on the moving component 100, a stable and compact integrated platform is formed. This eliminates the need to design a large support structure for each function, helping to control the overall size and weight of the device while ensuring functionality. Through the combination of mobile inspection and circumferential scanning, this device can efficiently complete comprehensive inspection of long-distance cables, providing extremely rich and accurate data for cable condition assessment, hazard location, and lifespan prediction.

[0060] Specifically, the monitoring element 220 has multiple components. The monitoring element 220 can be an infrared temperature measurement module: by measuring the temperature distribution on the surface of the cable, it can detect problems such as overheating or local temperature rise in the cable; it can also be a high-frequency current transformer monitoring module: using a high-frequency current transformer to monitor the operating status of the cable; it can also be an infrared thermal imaging detection module: using infrared thermal imaging technology to detect the temperature distribution of the cable; it can also be an ultrasonic detection module: by detecting ultrasonic signals, it can locate internal defects in the cable; it can also be a magnetic induction detection and electric field induction detection module: using changes in magnetic and electric fields to detect the status of the cable.

[0061] During use: The moving component 100 is placed on the power cable to be tested, so that it surrounds the cable. The device is started, and the moving component 100 begins to drive the entire device to move along the cable axis. The monitoring element 220 continuously acquires the cable surface condition information in the direction it faces.

[0062] refer to Figure 2 In some possible implementations, the mounting frame 210 is provided with a plurality of blades 230, which are arranged around the outside of the mounting frame 210, and the mounting frame 210 abuts against the moving component 100 through the plurality of blades 230.

[0063] In some possible implementations, the mounting frame 210 is rotatably disposed inside the movable component 100.

[0064] Multiple blades 230 can rotate about the axis of the mounting frame 210 to drive the mounting frame 210 to rotate relative to the moving component 100.

[0065] It is known that the mounting frame 210 is not fixed to the moving component 100, nor can it only move along the axial direction. Instead, it is connected by a rotating joint of the blade 230, which allows the mounting frame 210 to rotate relative to the moving component 100 about its own axis (which is approximately coincident with the cable axis).

[0066] The blades 230 are protruding structures fixed to or formed on the outer circumference of the mounting frame 210, and there are multiple blades distributed circumferentially. The mounting frame 210 transmits force and motion through the contact between the ends of the blades 230 and the inner surface of the moving assembly 100.

[0067] The blade 230 is not only a static support component but also a dynamic transmission component. By pushing the blade 230, the entire mounting frame 210 is moved relative to the moving component 100. The rotation of the blade 230 is the driving source of the mounting frame 210, and the rotational motion of the blade 230 is converted into torque that drives the entire mounting frame 210 to rotate.

[0068] By uniformly contacting the inner wall of the moving component 100 with the multiple circumferential blades 230, the driving force can be evenly distributed and transmitted along the circumference of the mounting frame 210, making the movement of the mounting frame 210 and its monitoring element 220 lighter and smoother. This achieves the integration of the overall movement function of the moving component 100 and the "fine scanning" function of the monitoring component 200 in the mechanical structure. Since the mounting frame 210 itself does not need to support the bulky axial drive motor and transmission mechanism, the structure of the mounting frame 210 can be designed to be more compact and lightweight, which helps to achieve the miniaturization and multi-functionality of the device. By having multiple blades 230 arranged in a circle and simultaneously contacting the moving component 100, multi-point support and guidance are formed, ensuring the stability of the mounting frame 210 during axial movement, preventing it from swaying or jamming, and ensuring the accuracy and repeatability of the scanning path of the monitoring element 220, thereby improving the quality of the monitoring data.

[0069] In some embodiments, the blade 230 is integrally formed with the mounting frame 210.

[0070] In some possible implementations, the moving component 100 is provided with a mounting groove 101, and the blade 230 is disposed within the mounting groove 101.

[0071] And / or, the moving component 100 is provided with a purge drive 300, which is used to purge the cable and can be reused to drive the blade 230 to move relative to the moving component 100.

[0072] Specifically, the purge drive 300 is located at the bottom of the moving component 100. The purge drive 300 blows air to the blade 230 through the air blowing channel 310 opened in the moving component 100. An air outlet 320 is opened on the mounting frame 210, and the air outlet 320 faces the inside of the monitoring component.

[0073] It is understood that the mounting groove 101 is a groove or track structure formed on the inner wall of the moving component 100, and its shape is adapted to the contour of the blade 230 and the mounting frame 210. The radial position and movement trajectory of the blade 230 are precisely defined by the mounting groove 101, which ensures that multiple blades 230 can move stably along a preset path and maintain a reliable contact relationship with the inner wall of the moving component 100.

[0074] The airflow generated by the blowing drive 300 (such as a fan or air pump) is not only used to guide the movement of the drive blades 230, but can also directly blow away the cable. The airflow is generated from the bottom of the blowing drive 300, guided to the blades 230 through the blowing channel 310, impacts the blades 230, and uses the kinetic energy of the airflow to drive the blades 230 to rotate, causing the mounting frame 210 to move relative to the moving component 100. The airflow after driving the blades 230 is not directly discharged to the outside, but is guided to the cable surface through the air outlet 320, which can also blow away the cable surface, not only blowing away dust and debris, but also drying the cable surface.

[0075] In this way, the rotation drive function of blade 230 and the cable surface purging function can be realized by a single purging drive component 300. Both functions can be achieved simultaneously with a single power source, simplifying the internal mechanical structure of the moving component 100 and saving space and weight. Using airflow to drive the rotation of blade 230 avoids the wear, vibration and noise that may be caused by gear meshing or friction transmission, making the rotation of mounting frame 210 smoother and quieter, and requiring no lubrication, thus reducing maintenance needs. Directional purging of the bottom of the cable through the air outlet 320 can effectively dry the condensate or slight water film on the cable surface, which not only improves the insulation surface condition of the cable and reduces the risk of flashover caused by surface dirt and moisture, but also provides a drier and cleaner observation surface for monitoring element 220, reducing the interference of water film on temperature measurement and image recognition, thereby improving the accuracy and reliability of monitoring data.

[0076] Usage process:

[0077] After the device is started, the blowing drive 300 located at the bottom of the moving component 100 starts to work, generating an airflow with a certain pressure and flow rate. The airflow is guided to the mounting groove 101 area through the pre-set blowing channel 310 inside the moving component 100 and impacts the blades 230 located in the mounting groove 101. The airflow exerts a force on the blades 230, driving multiple blades 230 to rotate around the axis of the mounting frame 210, causing the mounting frame 210 to rotate relative to the moving component 100.

[0078] The airflow after driving the blade 230 is ejected from the air outlet 320 opened on the mounting frame 210 and directed toward the cable surface inside the monitoring component. This airflow sweeps the cable surface to achieve the effect of drying and cleaning.

[0079] The rotating mounting frame 210 drives the monitoring element 220 to perform a circumferential scan of the cable, while continuous purging provides better cable surface conditions for monitoring. The moving component 100 can simultaneously drive the entire device to move along the cable axis, realizing dynamic monitoring covering the entire cable with surface treatment functions.

[0080] refer to Figure 3 In some possible implementations, the mounting frame 210 includes a first mounting member 211, a second mounting member 212, and an elastic member 213.

[0081] The first mounting component 211 and the second mounting component 212 are disposed inside the movable component 100.

[0082] The elastic element 213 is disposed between the first mounting member 211 and the second mounting member 212, and the elastic element 213 can apply a force to the first mounting member 211 and the second mounting member 212 to bring them closer together.

[0083] In some embodiments, a metal connecting frame 400 for communication transmission and power transmission is fixedly mounted on the outer side of the first mounting member 211 and the second mounting member 212. The metal connecting frame 400 can be used for communication transmission and power transmission of the monitoring element 220.

[0084] The metal connecting frame 400 synchronous first mounting part 211 and second mounting part 212 are also designed as separate units.

[0085] It is understood that the split structure design of the mounting frame 210 consists of a first mounting member 211, a second mounting member 212, and an elastic member 213 connecting them. The first mounting member 211 and the second mounting member 212 are both independently mounted inside the movable assembly 100.

[0086] The elastic element 213 provides a continuous preload that presses the first mounting element 211 and the second mounting element 212 together, ensuring that the two separate components remain a stable integral structure under dynamic working conditions and preventing loosening or misalignment due to vibration or force.

[0087] A frame-like structure made of metal material is additionally installed on the outer surface of the first mounting component 211 and the second mounting component 212 to provide a communication transmission channel for the monitoring element 220 and to supply power to the monitoring element 220.

[0088] When the first mounting member 211 and the second mounting member 212 close under the action of the elastic member 213, the various parts of the metal connecting frame 400 also align, forming a complete electrical connection and functional loop. The elastic member 213 also provides a continuous clamping preload to the separate metal connecting frame 400 to ensure that the electrical connection is not interrupted.

[0089] The modular, openable structure formed by the first mounting component 211, the second mounting component 212, and the elastic component 213 allows the entire mounting frame 210 to open like a clamp, facilitating the insertion of cables. Then, under the pre-tightening force of the elastic component 213, it automatically closes and grips the cables, simplifying the installation and disassembly process. Simultaneously, the elastic grip adapts to minor changes in cables of different diameters and buffers vibrations during device movement, ensuring a stable relative position between the mounting frame 210 and the cables. The continuous clamping force provided by the elastic component 213 ensures stable and reliable electrical contact at the mating points of the metal connection frame 400, preventing power outages or communication signal attenuation due to poor contact during device movement and vibration, thus guaranteeing the continuous and stable operation of the monitoring element 220.

[0090] In some possible implementations, there are multiple elastic elements 213, including a first elastic element 2131 and a second elastic element 2132.

[0091] One end of the first mounting member 211 is connected to the second mounting member 212 via the first elastic member 2131, and the other end of the first mounting member 211 is connected to the second mounting member 212 via the second elastic member 2132.

[0092] It is understandable that the first elastic element 2131 and the second elastic element 2132 provide the basis for multi-point elastic connection. The first elastic element 2131 and the second elastic element 2132 are respectively disposed at both ends of the first mounting member 211. This arrangement forms an elastic constraint at least at two points between the first mounting member 211 and the second mounting member 212, so that when the first mounting member 211 and the second mounting member 212 are closed, the elastic preload force at both ends is relatively independent and can be adjusted or designed separately, which helps to establish a more balanced and stable closing pressure distribution between the two.

[0093] In this way, by independently setting the first elastic element 2131 and the second elastic element 2132 at both ends of the first mounting component 211, the closing pre-tightening force between the first mounting component 211 and the second mounting component 212 has at least two clear and symmetrically positioned force application points. This avoids the problem of incomplete closure or uneven pressure at the other end that may be caused by applying force at a single point. It ensures that the first mounting component 211 and the second mounting component 212 can uniformly and stably grip the cable along their entire contact length or contour, improving the overall attachment stability and anti-torsion and anti-sway capabilities of the mounting frame 210 on the cable. The multi-point elastic support can more effectively absorb and disperse the vibration generated during the movement and rotation of the device, protecting precision components such as the monitoring element 220 and the metal connecting frame 400. The symmetrical arrangement of the first elastic element 2131 and the second elastic element 2132 ensures that the elastic resistance to be overcome when opening or closing the mounting frame 210 is balanced at both ends, allowing operators to perform installation and disassembly operations more smoothly and effortlessly.

[0094] refer to Figure 4 In other embodiments, the elastic element 213 is a ring structure, and the outer side of the mounting frame 210 has an elastic element mounting groove. By fitting the elastic element 213 into the elastic element mounting groove, a force is applied to the first mounting member 211 and the second mounting member 212 to bring them closer together.

[0095] In some possible implementations, a fixing groove 201 is provided on the inner side of the mounting frame 210, and the monitoring element 220 is disposed in the fixing groove 201.

[0096] And / or, the mounting frame 210 is provided with a snap-fit ​​connector, and the monitoring element 220 is snap-fitted into the mounting frame 210 via the snap-fit ​​connector.

[0097] It is known that the fixing groove 201 is a groove or cavity formed on the inner surface of the mounting frame 210 facing the cable, the shape of which is adapted to at least a part of the shape of the monitoring element 220 for accommodating and positioning the monitoring element 220.

[0098] The snap-fit ​​component (not shown in the figure) is an independent mechanical structure (such as a snap-fit, spring, or hook) mounted on the mounting frame 210. The monitoring element 220 has a corresponding mating structure (such as a slot or flange). Through the snap-fit ​​engagement between the two, the monitoring element 220 can be quickly installed and locked on the mounting frame 210 without the need for screws or other fasteners.

[0099] It should be noted that the installation methods of the fixing slot 201 and the snap-fit ​​connector are not mutually exclusive, but can be used individually or in combination. For example, positioning and limiting can be achieved solely through the fixing slot 201; quick mounting can be achieved solely through the snap-fit ​​connector; or the monitoring element 220 can be pre-positioned within the fixing slot 201 and then finally locked in place using the snap-fit ​​connector, combining the advantages of both methods.

[0100] The fixing slot 201 provides a precise mechanical positioning reference for the monitoring element 220. Embedding the monitoring element 220 into the fixing slot 201 allows for strict control of its radial distance, observation angle, and circumferential position relative to the mounting frame 210 (and thus relative to the cable), ensuring the accuracy and comparability of the monitoring data. At the same time, the slot structure effectively prevents the monitoring element 220 from shifting or loosening during device movement and rotation.

[0101] The snap-fit ​​design provides a quick installation and removal method with no or only simple tools, making it easy to install, replace or upgrade the monitoring element 220, improving the maintainability and task flexibility of the device and reducing downtime.

[0102] In some possible implementations, the moving component 100 includes a body 110 and a moving element 120.

[0103] The main body 110 is arranged around the periphery of the cable, and the movable part 120 is arranged inside the main body 110. The movable part 120 is used to abut against the cable to drive the main body 110 to move relative to the cable.

[0104] It is understood that the main body 110 is a frame, shell, or ring structure that can surround the cable. It is the main supporting skeleton and functional integration platform of the mobile component 100. Components such as the mounting frame 210 and the purging drive unit 300 are all located on or inside the main body 110.

[0105] The movable component 120 is installed on the side of the main body 110 facing the cable. The movable component 120 is an actuating component that directly contacts the cable surface and generates driving force. Through the contact and interaction (such as friction drive) between the movable component 120 and the cable surface, the generated driving force is ultimately transmitted to the main body 110, thereby driving the entire movable assembly 100 and the monitoring assembly 200 it carries to move along the cable.

[0106] The balanced, large-area drive contact provided by the moving part 120 ensures that the driving force is efficiently and smoothly transmitted to the cable, reducing energy loss caused by slippage and idling, and improving travel efficiency.

[0107] In some possible implementations, the main body 110 includes a first support 111 and a second support 112 connected to each other.

[0108] The first bracket 111 is disposed above the second bracket 112, and a connecting structure 500 is provided between the first bracket 111 and the second bracket 112. The first bracket 111 and the second bracket 112 are fixed or released through the connecting structure 500.

[0109] It is understood that the first bracket 111 and the second bracket 112 together form the main body 110 frame surrounding the cable. In the working posture of the device, the first bracket 111 is located in the area above the cable, while the second bracket 112 is located in the area below or to the side of the cable. The main body 110 surrounds the cable in a vertically aligned or vertically combined manner.

[0110] The main body 110 has two operable states. In the fixed state, the first bracket 111 and the second bracket 112 are locked by the connecting structure 500, so that the first bracket 111 and the second bracket 112 are firmly connected together to form a stable ring-shaped main body. In the released state, the connecting structure 500 releases the locking of the first bracket 111 and the second bracket 112, allowing the two to separate or open relative to each other.

[0111] Specifically, the mating points of the first mounting member 211 and the second mounting member correspond to the mating points of the first bracket 111 and the second bracket 112, so that the first mounting member 211 and the second mounting member can open and close together with the first bracket 111 and the second bracket 112.

[0112] By incorporating a releasable connection structure 500, the first bracket 111 and the second bracket 112 can be separated. This allows operators to first place the first bracket 111 above the cable, then close the second bracket 112 from below or the side of the cable, and finally secure them together using the connection structure. This easily completes the installation of the main body 110 onto the cable without the need for complex threading from the cable end. The disassembly process is the reverse, simplifying installation and disassembly operations and improving work efficiency and safety. The separable design of the first bracket 111 and the second bracket 112 reduces the longitudinal space requirements around the cable during installation. When the cable is close to the cable tray base plate, roof, or under other obstacles, the closing sequence and angle of the first bracket 111 and the second bracket 112 can be flexibly adjusted to avoid obstacles and complete the installation.

[0113] In some possible implementations, the movable member 120 is disposed on the surface of the first bracket 111 facing the second bracket 112, and the movable member 120 is used to abut against the top surface of the cable.

[0114] And / or, the moving part 120 is configured as a tracked moving part 120, and the moving direction of the tracked moving part 120 is set parallel to the axis of the mounting frame 210.

[0115] It is known that when the device is installed on the cable, the movable part 120 located at this position contacts the upper part (top surface) of the cable and provides driving force.

[0116] refer to Figure 5 Specifically, the moving part 120 includes a fixed frame 121, a drive roller 122 and a track 123. Multiple drive rollers 122 are arranged in the mounting frame, and the track 123 is sleeved on the drive rollers 122. The drive rollers 122 have toothed grooves on both sides, and the inner ends of the track 123 have teeth that cooperate with the toothed grooves.

[0117] Furthermore, the two ends of the fixing bracket 121 are mounted in the groove formed by the first bracket 111 via elastic mounting posts 124.

[0118] Furthermore, the outer diameter of the drive roller 122 gradually decreases from both sides towards the center, and the track 123 is elastic.

[0119] It is known that the entire tracked moving part 120 can be elastically pressed down by the flexible mounting post 124, adapting to changes in cable diameter.

[0120] The concave arc-shaped drive roller 122 is combined with the elastic track 123. When the track 123 is squeezed, the track 123 will simultaneously conform to the concave arc surface of the drive roller 122 and the cylindrical surface of the cable, so that the working section of the track 123 is deformed into a contact area that matches the curved surface of the cable, realizing a large-area strip contact, which provides reliable adhesion and traction for the moving part 120 to avoid slippage and improve the conveying and walking efficiency.

[0121] The toothed grooves on both sides of the drive roller 122 mesh with the teeth at both ends of the inner side of the track 123, ensuring the direct transmission of driving force from the drive roller 122 to the track 123. This effectively prevents the track 123 from sliding sideways or deviating during operation, and ensures the straightness and stability of the travel direction.

[0122] The flexible mounting posts 124 form a multi-level elastic buffer system, which can effectively absorb the impact and vibration generated when the equipment starts and stops, as well as when crossing small protrusions on the cable surface. This not only protects the transmission components of the tracked moving part 120 itself and extends its service life, but also reduces the instantaneous impact force on the cable sheath, achieves more flexible contact, and avoids wear on the cable surface.

[0123] During use, when the device is installed on the cable, the track 123 is pressed against the top surface of the cable. The elastic track 123 deforms, and its inner side is attached to the concave arc surface of the drive roller 122, while its outer side is tightly attached to the cylindrical top surface of the cable, forming a contact area.

[0124] The drive motor drives the drive roller 122 to rotate. Through the meshing of the tooth grooves and teeth, the drive roller 122 drives the track 123 to rotate. The static friction between the track 123 and the cable surface propels the entire moving assembly 100 to move along the cable axis.

[0125] During the movement, when encountering changes in cable diameter or uneven surfaces, the elastic mounting column 124 deforms, causing the fixed frame 121 to float relative to the first support 111. At the same time, the track 123 itself also undergoes adaptive deformation, always maintaining good contact and stable pressure with the cable surface, and buffering vibration.

[0126] In some embodiments, a wireless communication module 600 is provided on the top of the first bracket 111. The wireless communication module 600 can send the data collected by the monitoring element to the control terminal, thereby improving the monitoring response efficiency.

[0127] In some embodiments, a power supply module 700 is installed at the bottom of the second bracket 112, the functional module being used to provide power for the operation of the cable monitoring device.

[0128] The power supply module 700 is equipped with heat dissipation fins at the air inlet end of the blow-drive component 300. When the blow-drive component 300 rotates at high speed, the air drawn in from both sides will draw away the heat from the heat dissipation fins, thereby reducing the heat of the power supply module 700 and improving the stability of the battery in the power supply module 700.
