Description

Technical Field

[0001] The invention belongs to the technical field of power maintenance and relates to a self-locking maintenance wrist strap and a use method thereof. Background Art

[0002] During power system maintenance work, operators often need to operate in complex, dimly lit, and even confined environments, facing multiple challenges such as electrostatic discharge (ESD) risks, insufficient lighting, cluttered tool cables, and cumbersome maintenance records. In traditional operations, safety protection, localized lighting, tool securing, and data recording often rely on independent equipment. For example, these equipment include anti-static wristbands to release static electricity, handheld or head-mounted lighting devices to provide light, temporary tape or straps to secure test cables, and paper work orders or handheld terminals to record maintenance information. This decentralized equipment combination not only increases the burden on operators, resulting in cumbersome and inefficient operational processes, but also poses safety risks in emergencies due to inconvenient tool access or inadequate lighting.

[0003] Furthermore, existing anti-static wrist straps are limited in functionality, typically providing only simple grounding and discharge capabilities, and are unable to integrate expanded functions such as lighting or data logging. Conventional lighting tools, on the other hand, require handholding, leaving both hands trapped and unable to provide stable, directional light at all times during operations. Tool cable management often relies on makeshift measures, resulting in loose fixings, easy detachment, and cluttered work areas, impacting operational efficiency and safety. Furthermore, maintenance information is still largely recorded on paper, which can lead to data omissions, contamination, or loss, hindering real-time upload and digital management of information. This makes it difficult to meet the high standards of modern power systems for standardized and traceable maintenance operations. Summary of the Invention

For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] The present application will be described in further detail below with reference to the drawings: The first object of the present invention is to provide a self-locking maintenance wrist strap, such as Figure 1 Shown, including: A strip-shaped flexible belt body 1, wherein a flexible metal mesh is embedded in the interior along the length direction; The self-locking component includes a first Velcro hook surface 2 provided at one end of the strip-shaped flexible belt body 1 and a first Velcro loop surface 3 at the other end, wherein the first Velcro hook surface 2 and the first Velcro loop surface 3 cooperate with each other; a conductive contact is provided at the edge of the first Velcro hook surface 2, and a conductive fiber layer is provided at a corresponding position of the first Velcro loop surface 3. When the first Velcro hook surface 2 and the first Velcro loop surface 3 are bonded, the conductive contact contacts the conductive fiber layer and forms a closed electrostatic discharge circuit through the flexible metal mesh; A reflective and luminous module, comprising reflective sheets 4 and luminous sheets 5 alternately arranged on the surface of the strip-shaped flexible belt 1; The probe line fixing unit includes a plurality of groups of Velcro units 6 spaced apart on the strip-shaped flexible belt body 1, wherein the Velcro units include a second Velcro hook surface and a second Velcro loop surface that cooperate with each other; A light control module 7, which is integrated with a light sensor, and the light control module 7 is electrically connected to the light emitting sheet 5; The maintenance recording module includes an NFC tag arranged on the surface of the strip-shaped flexible belt body 1 and a data recording unit electrically connected to the NFC tag; the NFC tag pre-stores the unique identification information of the wristband and can write maintenance data including maintenance start time, equipment number and operation content through an external terminal.

[0026] The flexible metal mesh embedded along the length of the strip-shaped flexible band 1 not only enhances the band's mechanical strength and service life, but also provides a reliable electrical path for static discharge. The self-locking assembly, through the interaction of the Velcro hook and loop surface, enables quick donning and secure locking of the wristband. Conductive contacts are integrated into the hook edge, while a conductive fiber layer is positioned at the corresponding position on the loop surface. This allows the wristband to automatically and seamlessly form a closed static discharge circuit through the flexible metal mesh the moment it is donned and closed. This design can promptly and safely dissipate static charge accumulated on the human body, effectively preventing potential risks associated with static discharge when repairing precision electronic equipment or in flammable and explosive environments, providing crucial active safety protection.

[0027] The light reflection and light emitting module realizes double warning of passive light reflection and active lighting through the alternately arranged light reflection sheet 4 and light emitting sheet 5. The light emitting control module 7 integrated with a light sensor can sense the change of ambient light intensity in real time, automatically drive the light emitting sheet 5 to start under the condition of dim light, and ensure that the operating personnel always maintain high visibility in the night or places with insufficient light, thereby greatly improving the personal safety protection level. The wire exploration fixing unit provides convenient and flexible fixing points for test lead wires, temporary tools and the like through the reasonable distribution of a plurality of magic tape units 6, and helps to keep the operation site clean and orderly, and avoid low efficiency and safety hazards caused by cable entanglement or tool falling.

[0028] In addition, the wristband of the present application integrates a maintenance record module, the NFC tag serves as a data carrier, pre-stores a unique identity, and can write maintenance task information (such as equipment number, operation content, start time, etc.) conveniently by using a smart phone or other external terminal. The operating personnel can use the smart phone or other mobile terminal with NFC function carried on the body to conveniently read the task information. The data recording unit electrically connected with the NFC tag can accurately and automatically record the operation time, and write the key data back to the NFC tag after the operation is completed, so as to record the operation process information completely. This not only replaces the paper records which are easy to lose or damage, realizes the digital traceability and management of the maintenance process, but also provides a solid data foundation for subsequent data analysis, work time statistics and safety production responsibility identification, and effectively promotes the standardization and informatization construction of the maintenance operation.

[0029] Exemplarily, the strip-shaped flexible band body 1 is made of a glass fiber reinforced silicone composite material. The material system realizes excellent comprehensive performance by compounding high-strength glass fiber with a flexible silicone rubber matrix. It has a wide temperature resistance range and can work stably at an extreme low temperature of-40℃ and a high temperature of 180℃ for a long time, effectively avoiding the defects of traditional high polymer materials, such as brittle cracking at low temperature and softening deformation at high temperature, and ensuring the dimensional stability and functional reliability of the wristband in various harsh climates and industrial environments. In addition, in order to further improve the durability of the band body, a high-performance wear-resistant layer is uniformly coated on the outer surface thereof. The wear-resistant layer can be selected from a polyurethane coating, a hydrogenated nitrile rubber coating or other polymer coatings with similar excellent performance. This protective film can significantly enhance the ability of the band body surface to resist physical friction, mechanical scratching and chemical medium corrosion such as oil stains and common solvents in daily operation, thereby greatly delaying the wear and aging process of the material and prolonging the effective service life of the product.

[0030] The first magic tape hook surface 2 is made of nylon, and the first magic tape hair surface 3 is made of polyester fiber. The nylon material gives the hook surface excellent strength, wear resistance and repeated tearing durability, ensuring that the lock can still maintain reliable hooking force after long-term use. The hair surface made of polyester fiber material provides a soft and high-density velvet structure, which not only forms a uniform and firm adhesion with the nylon hook surface, but also has excellent anti-aging and weather resistance, and can resist the influence of common moisture, oil stains and dust environment.

[0031] The second magic tape hook surface and its corresponding second magic tape hair surface in the magic tape unit 6 are arranged on the surface of the strip-shaped flexible band 1 in a stacked manner, and an elastic spacing layer is provided between the second magic tape hook surface and the second magic tape hair surface. The elastic spacing layer provides a stable pre-opened structure for the magic tape unit 6 in a natural state, so that the operator can easily and quickly place the probe wire into the fixed position by touch even when wearing thick gloves or having poor visibility, greatly simplifying the operation process; at the same time, it can effectively avoid accidental adhesion of the magic tape hook surface and the hair surface in the non-use state.

[0032] The light-emitting sheet 5 includes a flexible circuit board as a carrier and a plurality of light-emitting devices arranged in an array on the flexible circuit board. The flexible circuit board is fixedly arranged on the surface of the strip-shaped flexible band 1 in a manner of adhesion, and is reliably electrically connected with the light-emitting control module 7 through internal wiring. The flexible circuit board perfectly fits the bending and deformation of the wristband during wearing and using due to its excellent flexible characteristics, thereby ensuring that the entire light-emitting unit will not be broken, disconnected or degraded in performance even under harsh use conditions such as frequent bending, winding or twisting, greatly guaranteeing the long-term stability and reliability of the lighting function. In terms of power supply, a micro battery integrated in the light-emitting control module 7 or an external power supply interface provides electric energy, which is output to the flexible circuit board through the light-emitting control module 7, and then drives the light-emitting devices on the flexible circuit board to emit light. Preferably, the light-emitting devices are high-brightness and low-power glass microsphere packaged LEDs, which not only emit light uniformly and softly with a wide illumination range, but also have a solid structure and are resistant to impact and vibration, making them very suitable for use in complex activity environments such as industrial maintenance.

[0033] The surfaces of the reflective sheet 4 and the light-emitting sheet 5 are provided with a transparent wear-resistant protective layer, which can effectively isolate dust, oil stains, moisture and chemical substances from penetrating into the interior and affecting the optical performance or causing a short circuit. At the same time, its solid and wear-resistant surface characteristics can resist frequent friction and scratching with equipment, tools and rough surfaces during maintenance, avoiding the reflective microbeads in the reflective sheet 4 from falling off or the light-emitting sheet 5 from being scratched, thereby maintaining the high-brightness reflective effect and clear illumination light pattern for a long time.

[0034] In addition, the light-emitting control module 7 is also integrated with a motion sensor. After the integration of the motion sensor, the light-emitting control module 7 realizes the leap from simple light control to intelligent sensing. The sensor can accurately detect the motion state of the wristband. When it is identified that the wearer is in long-term static state, the lighting brightness can be automatically reduced or the sleep state can be entered, thereby reducing the energy consumption. Once the limb activity is detected, the full brightness lighting is immediately restored to ensure seamless connection of work. The energy waste caused by the non-operation period such as rest and standby can be effectively avoided, and the battery endurance time is significantly prolonged.

[0035] Embodiment The embodiment provides a self-locking maintenance wristband, which comprises: A strip-shaped flexible band body 1 is integrally formed by glass fiber reinforced silicone, has a thickness of 2 mm, a length that can be adapted to different wrist circumferences in a range of 30 to 40 cm, and a uniform width of 5 cm. The band body can maintain structural stability and flexibility in an extreme temperature range of -40 DEG C to 180 DEG C, and the surface is compounded with a polyurethane wear-resistant coating (hardness HRC30), which significantly improves the anti-scratching and corrosion resistance.

[0036] A self-locking assembly comprises magic tape structures arranged at two ends of the strip-shaped flexible band body 1. One end is a first magic tape hook surface 2 (area 10 cm 2 ) made of nylon, and the other end is a first magic tape hair surface 3 (area 15 cm 2 ) made of polyester fiber. After the first magic tape hook surface 2 and the first magic tape hair surface 3 are attached to each other, a maximum adhesion of not less than 10 N can be provided, and the gap around the band body after locking is not more than 1 mm, thereby ensuring reliable fastening and dust prevention.

[0037] A reflective light-emitting module comprises reflective sheets 4 and light-emitting sheets 5 alternately arranged on the surface of the strip-shaped flexible band body 1. The whole has an IP67 protection level, can effectively prevent dust from entering and be affected by temporary immersion, and ensure continuous and stable work in harsh environments such as humidity and dust.

[0038] A lead fixing unit comprises a plurality of magic tape units 6 spaced apart on the strip-shaped flexible band body 1. The magic tape unit comprises a second magic tape hook surface and a second magic tape hair surface that cooperate with each other. After being attached, a closed fixed ring is formed, which can be adapted to a lead with a diameter of 3 to 6 mm, and the adhesion of a single group is not less than 4 N.

[0039] A light-emitting control module 7 is integrated with a light sensor with a range of 0 to 2000 lux and is powered by a CR2032 battery. The light-emitting sheet 5 can be intelligently controlled according to the ambient brightness: it is automatically turned on when the ambient brightness is lower than 50 lux, and it is turned off when the ambient brightness is higher than 200 lux, thereby realizing energy-saving automatic lighting.

[0040] The maintenance recording module includes an NFC tag arranged on the surface of the strip-shaped flexible belt body 1 and a data recording unit electrically connected to the NFC tag; the NFC tag pre-stores the unique identification information of the wristband and can write maintenance data including maintenance start time, equipment number and operation content through an external terminal.

[0041] A second object of the present invention is to provide a method for using a self-locking maintenance wrist strap, comprising the following steps: First, wrap the strip-shaped flexible belt 1 around the operator's wrist, and adhere the first Velcro hook surface 2 and the first Velcro loop surface 3 at both ends to each other (overlapping area ≥ 8cm 2 ) for fast wearing and firm locking, and ensures reliable contact between the conductive contacts and the conductive fiber layer, establishing an electrostatic discharge path; then, various probe wires that need to be temporarily fixed can be placed directly on the surface of the wristband, and the Velcro unit 6 on its surface is used to adhere and fix them, so that the probe wires can be easily fixed and quickly taken out; during this process, the light-emitting control module 7 on the wristband continuously and intelligently senses the ambient light intensity through the light sensor, and automatically activates the light-emitting sheet 5 to provide local lighting when in a dimly lit or nighttime working environment. In addition, manual control can also be performed by short-pressing the button on the light-emitting control module 7 to switch the brightness level. After the operation is completed, untie the first Velcro hook surface 2 and the first Velcro fleece surface 3, and store the strip-shaped flexible belt body 1 in a dry place after winding it.

[0042] During operation, the maintenance data is recorded by the data recording unit and stored in the NFC tag; the maintenance data including the maintenance start time, equipment number and operation content in the NFC tag is read or written by the external terminal.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
