Description

Technical Field

[0001] This utility model relates to the field of cable circulation device technology, and in particular to a light-emitting wireless circulation detector with mechanical adjustment of filter paper. Background Technology

[0002] With the ever-increasing demand for electricity, the reliability and safety of power systems have become paramount. Cables, as a crucial transmission medium in power systems, often bear the burden of transmitting high current and high power; therefore, monitoring the operational status of cables is one of the keys to ensuring the safe and stable operation of power systems. Traditionally, cable condition monitoring devices primarily use current or temperature sensors to acquire cable operating data, which can be remotely monitored and analyzed through a backend system. However, in some special situations, such as when cables are installed at high altitudes, underground, or in inaccessible locations, maintenance personnel often cannot observe the cable's operational status in a timely manner, thus increasing the risk of power system failures.

[0003] Chinese Patent Publication No. CN110954778A discloses a cable circulating current monitoring device, which includes multiple slave node systems deployed on-site to collect cable grounding circulating current status information and convert it into electrical signals, as well as to obtain cable positions and upload the electrical signals and cable positions to a master node system; a master node system for receiving the electrical signals and cable positions of the cable grounding circulating current status information uploaded by the multiple slave node systems, parsing the electrical signals of the cable grounding circulating current status information uploaded by the multiple slave node systems to obtain cable grounding circulating current status data, and sending it to a remote monitoring server; a communication network for data transmission between the master node system and the slave node systems, and between the master node system and the remote monitoring server; and a remote monitoring server for receiving the cable grounding circulating current status data sent by the master node system and remotely monitoring the slave node systems. This enables real-time monitoring of cable circulating current status and ensures the safe operation of the power grid.

[0004] Therefore, existing patents still have the following problems: They cannot be conveniently installed around the cable surface when the cable is already installed. More importantly, traditional cable circulation devices often fail to provide effective status indications when power is depleted or the electrical system malfunctions, preventing maintenance personnel from promptly assessing the cable's actual condition and thus delaying optimal troubleshooting, increasing potential risks to the power system. Utility Model Content

[0005] Therefore, this utility model provides a light-emitting wireless circulation detector with mechanical adjustment of filter paper to overcome the problems of slow fault response and inability to intuitively obtain fault information by the naked eye in the prior art.

[0006] To achieve the above objectives, this utility model provides a light-emitting wireless circulating current detector with mechanically adjustable filter paper, comprising:

[0007] A cable circulating current device is installed around the cable and is used to monitor the circulating current of the cable and output the corresponding current data.

[0008] The C-shaped openable and closable structural frame is mounted on the outside of the cable circulation device via a hinge structure.

[0009] A multi-color flexible LED light-emitting sheet is arranged around the outer wall of the C-shaped openable and closable structural frame and is electrically connected to the cable circulation device to emit light through the cable circulation current stored in the cable circulation device;

[0010] Two filter film rollers are provided, and the two filter film rollers are respectively disposed at the two end positions of the opening of the C-shaped openable and closable structural frame.

[0011] The filter film tape has its two ends respectively wrapped around the two filter film rollers so that the filter film tape is in close contact with the surface of the multicolor LED flexible light-emitting sheet and reflects the light emitted by the multicolor LED flexible light-emitting sheet or reflects sunlight.

[0012] Furthermore, the C-shaped openable and closable structural frame also includes a number of limiting posts disposed on the inner sidewall of the C-shaped openable and closable structural frame, wherein the cable circulation device is provided with a limiting groove on the outside that cooperates with the number of limiting posts, and the limiting posts are disposed inside the limiting groove and engaged with the limiting groove.

[0013] Furthermore, a number of limiting posts disposed on the inner sidewall of the C-shaped openable and closable structural frame are axially symmetrical along the axis of the hinge structure to the axis of the cable.

[0014] Furthermore, it also includes two motors, which are located at both ends of the opening of the C-shaped openable structural frame to drive the filter film roller to rotate, wherein both motors are electrically connected to the control circuit in the cable circulation device.

[0015] Furthermore, the filter film strip is rotatably connected to the filter film roller.

[0016] Furthermore, the filter film strip has multiple colors, wherein the length of each color is the length of the outer circumference of the C-shaped openable and closable structural frame.

[0017] Furthermore, the filter film strip includes at least three colors, which respectively represent "normal", "warning" and "error" states.

[0018] Furthermore, the color of the filter film is red, yellow, or green.

[0019] Furthermore, the cable circulation device has a low-power mode and periodically wakes up to perform status checks and color indicator updates.

[0020] Furthermore, the cable circulation device also includes a light sensor and a current sensor disposed therein. The light sensor is used to monitor the external light intensity, and the current sensor is used to monitor the current data of the cable circulation device.

[0021] Compared with the prior art, the beneficial effect of this utility model is that it adds a large area of ​​multi-color filter film, and under strong light or low light conditions at night, the filter film reflects different colors by reflecting the multi-color LED flexible light-emitting sheet or sunlight onto the filter film, so that the filter film can display different color indicators. This ensures that users can accurately see the operating status of the cable no matter what lighting conditions are available. This design significantly improves the adaptability of the system and is suitable for various actual working environments.

[0022] Meanwhile, through periodic wake-up and status checks, energy can be saved and the service life of equipment can be extended while maintaining long-term operation, meeting the energy efficiency requirements of modern equipment. Attached Figure Description

[0032] Please see Figures 1-3 As shown, Figure 1 This is a schematic diagram of the overall structure of the luminescent wireless circulating current detector for mechanically adjusting filter paper according to this utility model. Figure 2 This utility model Figure 1 Enlarged schematic diagram of the structure at point A in the middle. Figure 3 This is a schematic diagram of the hinge structure in the luminescent wireless circulating current detector with mechanically adjustable filter paper described in this utility model.

[0033] This utility model provides a light-emitting wireless circulating current detector for multi-color mechanically adjustable filter paper, comprising:

[0034] Cable circulation device 2 is arranged around cable 1 and is used to monitor the circulating current of cable 1 and output current data;

[0035] The C-shaped openable and closable structural frame 3 is mounted on the outside of the cable circulation device 2 via a hinge structure 7.

[0036] A multi-color LED flexible light-emitting sheet 4 is arranged around the outer wall of the C-shaped openable and closable structural frame 3 and is electrically connected to the cable circulation device 2 so as to emit light through the cable 1 circulation current stored in the cable circulation device 2.

[0037] There are two filter film rollers 6, and the two filter film rollers 6 are respectively located at the two end positions of the opening of the C-shaped openable and closable structural frame 3.

[0038] The filter film strip 5 is respectively wrapped around two filter film rollers 6 at both ends, so that the filter film strip 5 is closely attached to the surface of the multi-color LED flexible light-emitting sheet 4 and reflects the light emitted by the multi-color LED flexible light-emitting sheet 4 or reflects sunlight.

[0039] In this embodiment of the utility model, the C-shaped openable and closable structural frame 3 also includes a plurality of limiting posts 8 disposed on the inner side wall of the C-shaped openable and closable structural frame 3. The cable circulation device 2 is provided with a limiting groove on the outside that cooperates with the plurality of limiting posts 8. The limiting posts 8 are disposed inside the limiting groove and are engaged with the limiting groove. During installation, the C-shaped openable and closable structural frame 3 will rotate to open the opening through the hinge structure 7 and be installed on the outer side wall of the cable circulation device 2 through the opening. At this time, the limiting posts 8 are located inside the limiting groove, and the limiting posts 8 are engaged with the limiting groove, thereby preventing the C-shaped openable and closable structural frame 3 from falling off the cable circulation device 2.

[0040] Specifically, the several limiting posts 8 are axially symmetrical along the axis of the hinge structure 7 to the axis of the cable 1. The axially symmetrical arrangement makes the C-shaped openable and closable structural frame 3 more firmly installed on the outer surface of the cable circulation device 2, avoiding the occurrence of the C-shaped openable and closable structural frame 3 falling off and improving the installation stability of the C-shaped openable and closable structural frame 3.

[0041] Please see Figure 4 This is a schematic diagram of another embodiment of the overall structure of the luminescent wireless circulating current detector with mechanically adjustable filter paper described in this utility model. In another embodiment of this utility model, the limiting post 8 is disposed inside the C-shaped openable and closable structural frame 3 and abuts against the outer wall of the cable circulating device 2. This design greatly improves the stability of the installation of the C-shaped openable and closable structural frame 3 and the cable circulating device 2 when the C-shaped openable and closable structural frame 3 is installed on the cable circulating device 2, while also ensuring the integrity of the outer wall of the cable circulating device 2.

[0042] This embodiment of the utility model also includes two motors, which are located at both ends of the opening of the C-shaped openable and closable structural frame 3 and electrically connected to the control circuit in the cable circulation device 2. Each motor can rotate independently at different directions and speeds. When one motor rotates actively, the other motor rotates passively only by following the rotation of the filter film belt 5, so as to play an auxiliary guiding role in the rotation of the filter film belt 5. When the filter film belt 5 abnormally comes off, the filter film belt 5 can be safely and conservatively recovered by pulling the filter film belt 5 with each filter film roller 6 at different directions and speeds. At the same time, the filter film motor rollers can also drive the filter film to move, thereby enabling the filter film to switch to different colors to adjust the displayed status color and realize instant and intuitive feedback on the status of the cable 1.

[0043] In this embodiment of the present invention, the filter film strip 5 is rotatably connected to the filter film roller 6. Specifically, the filter film strip 5 is snapped onto the filter film roller 6. However, it is worth noting that the filter film strip 5 in this invention can also be connected by having its entire end wrapped around the filter film roller 6. The connection method includes, but is not limited to, adhesive connection, nail connection, etc. This application does not make specific limitations on this. However, in this embodiment, the filter film roller 6 can be driven by a motor to rotate the filter film on the surface of the multi-color LED flexible light-emitting sheet 4, so that the light film strip can reflect the specific color light based on the actual current information of the cable 1, thereby ensuring that the color indication is consistent with the actual state of the cable 1 and improving the accuracy and response speed of the system.

[0044] In this embodiment, the filter film strip 5 has multiple colors, and the length of each color is the same as the length of the outer circumference of the C-shaped openable and closable structural frame 3. By using a filter film of the same length as the outer circumference of the C-shaped openable and closable structural frame 3, a single color in the filter film can completely cover the outer side of the C-shaped openable and closable structural frame 3, avoiding information loss or blurring due to insufficient indicator area and improving the indication effect.

[0045] Specifically, the filter film strip 5 includes at least three colors, which represent "normal", "warning", and "error" states respectively. The colors of the filter film strip 5 are red, yellow, and green, representing "normal", "warning", and "error" states respectively. For example, the filter film strip 5 has three colors: "red, yellow, and green", where "normal" is "green", "warning" is "yellow", and "error" is "red". This design ensures the comprehensiveness of color indication. In this embodiment, the system automatically selects an appropriate color to display according to the operating status of the cable 1. Through the color change, the user can clearly identify the operating status of the cable 1, enhancing the operability of the device and the user experience.

[0046] In this embodiment of the invention, to save power of the cable circulation device 2, the cable circulation device 2 will operate in a low-power mode. That is, the internal MCU unit in the cable circulation device 2 will enter a low-power sleep state and will be woken up by the RTC unit in the internal cable circulation device at regular intervals. This effectively reduces the energy consumption of the device, extends the battery life, and maintains the status update and indication functions of the device, ensuring that the device is always in the optimal state during long-term operation and avoiding potential problems caused by local errors.

[0047] In this embodiment of the invention, the cable circulation device 2 further includes a light sensor and a current sensor disposed therein. The light sensor is used to monitor the external light intensity, and the current sensor is used to monitor the current data of the cable circulation device 2. The current sensor is embedded to monitor the current data and reflects the real-time operating status of the cable 1 based on the data from the current sensor.

[0048] Specifically, the cable circulation device 2 is also equipped with a light sensor to detect the brightness of ambient light.

[0049] When the intensity of sunlight during the day is greater than the luminous intensity of the multi-color LED flexible light-emitting sheet 4, the strong sunlight can be reflected by the filter film strip 5 to reflect the color corresponding to the filter film strip 5, so that the color indication can be observed by the outside world even during the day when the light is strong. At night, the light emitted by the multi-color LED flexible light-emitting sheet 4 can pass through the "filter film strip 5" to the outside world, so that the color indication can be observed by the outside world even at night. Moreover, at the last moment before the planned power of the cable circulation device 2 is exhausted, the filter film strip 5 can still be rotated to the appropriate indication position by the filter film roller 6 so that the indication status can continue after the electrical part of the device fails.

[0050] The following is a general description of specific embodiments of this utility model:

[0051] In use, the C-shaped openable and closable structural frame 3 is tightly fitted with the cable circulation device 2. At the same time, a multi-color LED flexible light-emitting sheet 4 of various colors is installed on the outside of the C-shaped openable and closable structural frame 3 to emit light through the current in the cable circulation device 2 and display status information. In addition, two filter film rollers 6 are assembled at both ends of the C-shaped openable and closable structural frame 3. These two rollers are respectively connected to the filter film belt 5. By rolling the filter film belt 5, the color display is adjusted so that different cable 1 statuses can be indicated by different colors.

[0052] The filter film strip 5 includes multiple colors, such as "green," "yellow," and "red," representing "normal," "warning," and "error" states, respectively. The filter film strip 5 displays different colors by rotating the filter film roller 6. In strong daylight, the filter film strip 5 reflects sunlight, ensuring clear color indication; at night, the LED light-emitting sheet emits the corresponding color light, ensuring intuitive viewing of the device status even in low-light environments.

[0053] In addition, this invention employs a light sensor to automatically adjust the brightness of the multi-color LED flexible light-emitting sheet 4 to adapt to different lighting conditions. When the sunlight is strong during the day, the light sensor can detect and adjust the brightness of the LED accordingly to prevent the battery from being consumed too quickly; while in low-light environments, the system will provide sufficient brightness through the LED light-emitting sheet so that even in the absence of light, the user can see the status of the indicator.

[0054] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
