Description

Technical Field

[0001] This invention relates to the field of auxiliary protection technology for laser obstacle removal equipment, and more specifically, to a light shielding and protection device for a laser obstacle removal instrument. Background Technology

[0002] Laser obstacle removal equipment is widely used in scenarios such as power line inspection and outdoor operations, and its supporting shading and protection devices directly affect the safety and convenience of operation. Currently, existing shading and protection devices for laser obstacle removal equipment have many technical defects, making it difficult to meet actual operational needs: Firstly, a single shading structure cannot meet the shading requirements under different working conditions; secondly, traditional shading devices lack expandable sub-plate structures, resulting in a limited shading range and inability to adapt to different working conditions; thirdly, most shading devices are designed with a fixed angle, unable to flexibly adjust the angle according to outdoor operating scenarios, resulting in limited shading effectiveness; and fourthly, although some devices have adjustable structures, their positioning is unstable after adjustment, easily becoming loose and affecting operational safety.

[0003] Meanwhile, existing protective structures are poorly designed, mostly consisting of bolt-fixed covers that are cumbersome to install and remove, and offer limited protection, failing to provide comprehensive protection for core components such as the light-shielding components and hinged structures. Some magnetic protective structures rely on a single magnet for adhesion, resulting in insufficient tightness and susceptibility to detachment due to vibration, leading to poor protective performance. Furthermore, existing light-shielding devices are mostly planar structures that do not match the front contours of laser obstacle removal equipment, and the separate design of the light-shielding and protective components increases the size of the equipment and operational complexity. Existing devices do not adequately consider the complex outdoor environment, resulting in insufficient protective performance and making it easy for light-shielding components and supporting structures to be damaged, thus affecting the equipment's lifespan.

[0004] Based on the shortcomings of the existing technologies, in order to solve the problems of inconvenient adjustment of the shading angle, poor shading effect, poor protection effect, and cumbersome disassembly and assembly, and to meet the outdoor operation needs of laser obstacle removal equipment, it is urgent to develop a flexible, comprehensive, and easy-to-disassemble shading and protection device for laser obstacle removal equipment to make up for the shortcomings of the existing technologies. Summary of the Invention

[0005] In view of this, the present invention proposes a light-shielding and protective device for a laser obstacle clearing instrument, which aims to solve the problems of inconvenient light-shielding angle adjustment, poor light-shielding effect, poor protective effect, and cumbersome disassembly and assembly in the current technology.

The main light-shielding plate is also equipped with left and right side outlets. The outlet contours are adapted to the light-shielding sub-plate for smooth entry, exit and sliding guidance of the light-shielding sub-plate.

[0008] Furthermore, the light-shielding sub-plate is configured in an arc shape, and two light-shielding sub-plates are provided. The light-shielding subplate is slidably disposed on the left and right sides of the light-shielding main plate, forming a complete light-shielding surface with the light-shielding main plate; the light-shielding subplate is slidably engaged with the damping sheet slide rail inside the light-shielding main plate based on the guide rail mating parts on both sides of the light-shielding subplate, and a limiting part is provided at one end of the light-shielding subplate that extends into the light-shielding main plate, and a handle part is provided at the outer end of the light-shielding subplate away from the light-shielding main plate. The handle is designed with a raised structure for finger pulling, making it convenient for operators to quickly pull out the light-shielding sub-panel.

[0009] Furthermore, the angle support assembly includes a gas spring telescopic rod; Two gas spring telescopic rods are provided, and the two gas spring telescopic rods are symmetrically arranged on the left and right sides along the central axis of the base body. Each gas spring telescopic rod can extend and retract axially. The lower end of the gas spring telescopic rod is hinged to the base body, and the upper end is hinged to the bottom of the arc-shaped light-shielding main board. Based on the telescopic movement, the arc-shaped light-shielding main board is driven to rotate around the hinge structure for angle adjustment and positioning.

[0010] Furthermore, the magnetic attraction assembly includes a first annular magnet disposed on the substrate body, and a magnet that... The first annular magnet is attracted to the magnetic attraction component located inside the protective assembly.

[0011] Furthermore, the protective component includes a protective cover, the outline of which is adapted to the outer periphery of the base body near the light-shielding component, the depth of which is adapted to the overall height of the light-shielding component after it is retracted, and the protective cover is tightly attached to the base body based on a magnetic attachment component, completely covering the light-shielding component inside, for dustproof, scratchproof and impact-proof protection of the light-shielding component.

[0012] Furthermore, the inner surface of the light-shielding motherboard is set as a matte light-absorbing surface to absorb strong light.

[0013] Furthermore, the gas spring telescopic rod is a pre-charged sealed structure, filled with high-pressure inert gas, requiring no additional inflation, and is used for the self-locking position of the main light-shielding plate from 0-90°.

[0018] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] In some embodiments of this application, a light-shielding and protective device for a laser obstacle clearing instrument is provided, including: a base body 100, a light-shielding component, an angle support component, a magnetic component, and a protective component; The base body 100 is used to be fixedly connected to the main unit of the laser obstacle removal device; The light-shielding component is rotatably connected to the base body 100 based on a hinge structure, and the angle support component is connected to the base body 100 and the light-shielding component respectively, and is used for angle adjustment and positioning. The magnetic suction component is disposed on the side of the base body 100 near the light-shielding component, and the magnetic suction component is detachably connected to the protective component; The protective component is used to protect the light-shielding component and the angle support component, and can also provide auxiliary protection for the end of the laser obstacle clearing device main unit that is close to the light-shielding component.

[0020] Specifically, the light-shielding assembly is based on a synergistic design of adjustable angle and expandable range, including a main light-shielding plate 200, a secondary light-shielding plate 210, and matching connecting and guiding structures. These components work together to achieve flexible light shading. The light-shielding assembly consists of the main light-shielding plate 200 and the secondary light-shielding plate 210. The main light-shielding plate 200 is designed with an arc-shaped structure to fit the front contour of the laser obstacle clearing device, ensuring a high degree of fit with the equipment and no light leakage during shading. The main light-shielding plate 200 is rotatably connected to the base body 100 based on a hinge structure. The hinge structure is specifically configured as a hinge shaft 220, which is horizontally fixedly installed at one end of the base body 100 near the main light-shielding plate 200. The rear end of the main light-shielding plate 200 forms a rotatable engagement with the hinge shaft 220. Through the fixed support of the hinge shaft 220, the main light-shielding plate 200 can flexibly rotate around the hinge shaft 220, thereby achieving different angle adjustments to adapt to the needs of blocking laser reflection light from different directions during outdoor operations. To enable flexible extension and retraction of the light-shielding sub-plate 210, two sets of damping plate slide rails 230 are fixedly installed inside the light-shielding main plate 200. The two sets of damping plate slide rails 230 are respectively installed at the front and rear ends inside the light-shielding main plate 200, forming a symmetrical and stable sliding guide structure. At the same time, outlets 240 are provided on the left and right sides of the light-shielding main plate 200. The outline of the outlets 240 is adapted to the shape of the light-shielding sub-plate 210. Through the guiding action of the damping plate slide rails 230, combined with the limiting guidance of the outlets 240, the light-shielding sub-plate 210 can smoothly move in and out along the slide rails, realizing flexible expansion of the light-shielding range. The damping plates can also provide a certain damping force to prevent the light-shielding sub-plate 210 from getting stuck or sliding randomly during the sliding process, ensuring that the adjustment process is stable and controllable.

[0021] Understandably, the arc-shaped light-shielding main board 200 is height-matched to the front contour of the laser obstacle clearing device, effectively reducing light leakage and improving the basic light-shielding effect. Simultaneously, it is rotatably connected to the base body 100 via the hinge shaft 220, allowing for flexible adjustment of the light-shielding main board 200's rotation angle to adapt to different laser reflection directions in various operating scenarios, preventing strong light from interfering with the operator's vision from different angles and ensuring operational safety. The two sets of damping slide rails 230 not only provide stable sliding guidance for the light-shielding sub-plate 210, ensuring smooth and unobstructed movement, but also achieve temporary positioning of the light-shielding sub-plate 210 after extension and retraction through damping force, preventing displacement of the light-shielding sub-plate 210 due to equipment vibration during operation. The light-shielding sub-plate 210 can flexibly expand its light-shielding range by extending and retracting left and right. Without increasing the overall size of the device, the light-shielding width can be flexibly adjusted according to light intensity and operating range, solving the problem of fixed light-shielding range and poor adaptability of traditional single light-shielding plates, and significantly improving the ability to block strong light reflected from different angles and intensities. The overall structure is compact and easy to operate. Angle adjustment and range expansion can be completed without complicated operations, making it suitable for complex outdoor operating environments of laser obstacle clearing devices. At the same time, the components are closely matched, with strong stability, and can operate stably for a long time, improving the practicality and service life of the device.

[0022] Specifically, the light-shielding sub-plate 210 adopts an arc-shaped structure design, consistent with the arc-shaped contour of the light-shielding main plate 200, ensuring that the two can form a complete and seamless light-shielding surface after being put together, preventing light from leaking from gaps and ensuring the light-shielding effect. Two light-shielding sub-plates 210 are provided, which are slidably installed on the left and right sides of the light-shielding main plate 200 respectively. The light-shielding sub-plate 210 has a guide rail mating part 250 integrally formed on both sides. The guide rail mating part 250 forms a precise sliding engagement with the damping plate slide rail 230 preset inside the light-shielding main plate 200. Through the close sliding of the guide rail mating part 250 and the damping plate slide rail 230, the light-shielding sub-plate 210 can flexibly extend and retract along the length direction of the light-shielding main plate 200. To prevent the secondary light-shielding plate 210 from completely detaching from the main light-shielding plate 200 during extension and retraction, a limiting part 260 is provided at the end of the secondary light-shielding plate 210 that extends into the main light-shielding plate 200. The limiting part 260 forms a limiting engagement with the end of the internal slide rail of the main light-shielding plate 200, limiting the maximum extension distance of the secondary light-shielding plate 210. At the same time, a handle part 270 is provided at the outer end of the secondary light-shielding plate 210 away from the main light-shielding plate 200. The handle part 270 is designed as a raised structure that is easy to pull with fingers. The raised structure increases the grip strength of the hand, making it convenient for the operator to manually and quickly pull out the secondary light-shielding plate 210, realizing the rapid adjustment of the light-shielding range. The overall structure works together to balance the flexibility of extension and retraction with the ease of operation.

[0023] Understandably, the arc-shaped light-shielding sub-plate 210 perfectly matches the curvature of the light-shielding main plate 200. The two sub-plates are installed on the left and right sides of the main plate respectively. After extension and retraction, they form a complete and seamless light-shielding surface with the main plate, effectively preventing light leakage and significantly improving the overall light-shielding effect. This solves the problem of large gaps and poor light-shielding effect in traditional light-shielding sub-plates 210 and main plates. The precise fit between the guide rail mating part 250 and the damping plate slide rail 230 ensures smooth and uninterrupted sliding of the light-shielding sub-plate 210. Simultaneously, the damping plate provides stable damping force, making the extension and retraction of the light-shielding sub-plate 210 smooth and allowing for temporary positioning at any extension or retraction position, preventing displacement of the sub-plate due to equipment vibration during operation. The limiting part 260 effectively prevents the light-shielding sub-plate 210 from detaching from the main plate, ensuring structural stability and operational safety, and preventing component damage. The 270 handle features a raised, finger-operated structure designed for easy, ergonomic movement. Operators can quickly and conveniently pull out the sub-plate without additional tools, significantly improving operational efficiency and meeting the convenience requirements of complex outdoor operations. The overall structure is rationally and compactly designed, flexibly expanding the shading range without increasing the overall size of the device. This adapts to the lighting requirements of different work scenarios, enhancing the device's practicality and ease of operation, and extending the lifespan of components.

[0024] Specifically, the gas spring telescopic rod 300 in the angle support assembly, as the core structure for achieving angle adjustment and stable support of the shading assembly, utilizes the elastic extension and contraction characteristics of the gas spring and a symmetrical force design, combined with a hinged connection, to achieve angle adjustment and reliable positioning of the shading assembly. The angle support assembly includes two gas spring telescopic rods 300, arranged symmetrically along the central axis of the base body 100 to ensure balanced force and avoid structural tilting caused by unilateral force. The gas spring telescopic rod 300 adopts a pre-pressurized sealed structure, eliminating the need for additional inflation. It is pre-filled with high-pressure gas, utilizing the compressibility and elastic restoring ability of the gas to achieve telescopic movement. The lower end of the gas spring telescopic rod 300 is rotatably connected to the base body 100 via a hinged seat, while the upper end is also hinged to the bottom of the arc-shaped shading main plate 200 via a hinged structure, forming a two-way hinged connection. When the angle of the light-shielding component needs to be adjusted, the gas spring telescopic rod 300 can extend and retract axially. This extension and retraction causes the arc-shaped light-shielding main plate 200 to rotate around its hinge point with the base body 100, thereby adjusting the tilt angle of the light-shielding component. Utilizing the elastic potential energy of the gas spring to provide stable support, and through its own locking characteristics, it can be positioned at any location after extension and retraction without the need for additional fixing structures. This ensures that the light-shielding component remains stable at different angles, meeting the light-shielding requirements of different operating scenarios. It achieves integrated angle adjustment and positioning, and the overall structure works in synergy with the base body 100 and the light-shielding component to ensure the stability of the device's operation.

[0025] Understandably, the gas spring telescopic rod 300, as the core component of the angle support assembly, offers significant advantages in its design, effectively solving the problems of poor stability and inconvenient adjustment inherent in traditional support structures. Firstly, the two symmetrically arranged gas spring telescopic rods 300, distributed symmetrically along the central axis of the main body 100, provide uniform support to the arc-shaped light-shielding main plate 200, preventing tilting and loosening of the light-shielding plate due to unilateral force, ensuring the installation stability of the light-shielding assembly. Simultaneously, the symmetrical design ensures balanced force distribution on the light-shielding assembly, preventing structural deformation caused by uneven force and improving the overall durability of the device. Secondly, the gas spring telescopic rod 300 adopts a pre-pressurized sealed structure, requiring no additional inflation or maintenance, making operation convenient and the telescopic process smooth. It allows for continuous adjustment of the light-shielding assembly angle, adapting to different operational scenarios and solving the problems of cumbersome operation and inaccurate positioning associated with traditional angle adjustment structures. Furthermore, the gas spring telescopic rod 300 features a reliable self-locking function, ensuring stable positioning after extension and retraction without the need for an additional locking mechanism. This simplifies the structural design and prevents loosening after adjustment, guaranteeing the stability of the shading component during operation. Its hinged connection also ensures flexible angle adjustment, allowing for precise adjustment of the shading component's tilt angle according to actual operational needs. This achieves comprehensive shading while reducing operational difficulty, adapting to complex outdoor working environments, and minimizing maintenance costs. This further enhances the practicality and reliability of the entire device, providing strong protection for operational safety.

[0026] Specifically, the magnetic attraction component, based on the physical property of magnets attracting opposite poles and combined with a precise matching design, enables a quick and detachable connection between the protective component and the base body 100, while ensuring the stability of the connection. The magnetic attraction component mainly consists of two parts: a first annular magnet 400 and a magnetic coupling component, which work together to achieve the attraction and fixation function. The first annular magnet 400 is fixedly installed on the side of the base body 100 near the light-shielding component, its installation position matching the coverage area of ​​the protective component, ensuring precise correspondence with the magnetic coupling component inside the protective component. The magnetic coupling component is fixedly set inside the protective component, its position and size perfectly corresponding to the first annular magnet 400, forming a precise attraction fit. Utilizing the physical property of magnets attracting opposite poles, the first annular magnet 400 and the magnetic coupling component attract each other, thereby achieving a detachable connection between the protective component and the base body 100. The annular structure design ensures that the attraction force is evenly distributed across the entire connection surface, avoiding the problem of loose attraction caused by uneven local force, while ensuring precise fit between the protective component and the base body 100 without misalignment. This structural design allows for the rapid installation and removal of protective components without the need for additional fixing parts, balancing connection stability and ease of operation, and is highly compatible with the overall protection and operational requirements of the device.

[0027] Understandably, the magnetic attachment system specifically addresses the technical pain points of existing protective structures, such as cumbersome assembly and disassembly, loose adhesion, and inaccurate positioning. Specifically: First, it employs a structure where a first annular magnet 400 and a corresponding magnetic attachment component engage. Utilizing the attraction between opposite poles of magnets, it achieves a quick and detachable connection between the protective component and the base body 100. Operators can easily install and remove the protective component without any tools, significantly improving operational convenience and meeting the rapid protection needs of complex outdoor work scenarios. Second, the annular structure design ensures that the attraction force is evenly distributed across the entire connection surface. Compared to traditional single-magnet attachment, this effectively avoids problems such as loosening or misalignment caused by uneven local force, ensuring a tight connection between the protective component and the base body 100. This prevents the component from detaching due to vibration or collisions during outdoor operations, thus guaranteeing the protective effect. Furthermore, the precise alignment of the first annular magnet 400 with the magnetic coupling component guides the protective assembly for rapid positioning and installation, preventing issues such as inadequate protection and component wear caused by misalignment. This also simplifies the structural design, eliminating the need for additional bolts, clips, or other fixing components, reducing the number of parts and lowering manufacturing costs. The overall structure is simple, reliable, and highly stable, enabling both rapid assembly and disassembly of the protective components while ensuring secure connections. This effectively protects core components such as the light-shielding assembly and angle support assembly, extending the overall service life of the device and enhancing its practicality and promotional value.

[0028] Specifically, the protective component, based on structural adaptation and magnetic fixing design, revolves around the structural design, adaptability, and fixing method of the protective cover 500 to achieve comprehensive and reliable protection for the light-shielding component. The core component of the protective component is the protective cover 500. The outline of the protective cover 500 is precisely designed to perfectly fit the outer periphery of the base body 100 near the light-shielding component, ensuring no gaps when the protective cover 500 and the base body 100 are in contact, preventing external impurities from entering through gaps. The depth of the protective cover 500 is precisely calculated to match the overall height of the light-shielding component after retraction, fully accommodating the light-shielding component in its retracted state, achieving complete coverage. The fixing method of the protective cover 500 relies on the magnetic component; through the magnetic attraction of the component, the protective cover 500 is tightly attracted and fixed to the base body 100. By utilizing the attraction between opposite poles of the first annular magnet 400 and the magnetic coupling component in the magnetic suction assembly, the protective cover 500 is quickly fixed. At the same time, by adapting the contour and depth of the protective cover 500 to the base body 100, it is ensured that the protective cover 500 can accurately cover the light-shielding assembly, completely enclosing the light-shielding assembly inside, isolating it from external dust, debris, and external interference such as collisions and scratches. This achieves dustproof, scratch-proof, and impact-proof protection for the light-shielding assembly. Working together with the magnetic suction assembly and the light-shielding assembly, it forms a complete protective system, ensuring the structural integrity of the light-shielding assembly in the non-working state.

[0029] Understandably, the protective components specifically address the technical pain points of existing protective structures, such as poor adaptability, incomplete protection, and inconvenient assembly and disassembly. Specifically: First, the outline of the protective cover 500 precisely matches the outer perimeter of the base body 100, and its depth matches the overall height of the retracted light-shielding component. This ensures the light-shielding component is completely enclosed, eliminating blind spots and effectively isolating dust, sand, and other impurities in the outdoor working environment. This prevents dust accumulation on the surface of the light-shielding component from affecting its light-shielding effect, while also resisting damage from external scratches and collisions, achieving comprehensive protection. Second, the protective cover 500 is tightly attached to the base body 100 using a magnetic attachment, eliminating the need for bolts, clips, or other additional fixing components. Operators can quickly install and remove the protective cover 500, making operation convenient and efficient, adapting to the rapid protection needs of complex outdoor working scenarios. Furthermore, the tight attachment method ensures that the protective cover 500 will not fall off due to vibration or collision during equipment transportation, storage, or movement, guaranteeing the reliability of the protection and preventing damage to the light-shielding component due to protection failure. The overall structure is reasonably designed and highly adaptable. It can achieve comprehensive protection without complicated operation, which not only protects the structural integrity of the shading components and extends their service life, but also improves the ease of operation and practicality of the entire device and reduces maintenance costs.

[0030] Specifically, the matte light-absorbing surface on the inner side of the light-shielding mainboard 200 is designed based on the physical properties of light reflection and absorption, combined with the operational requirements of the laser obstacle removal device, to achieve strong light absorption through a specific surface structure design. The inner side of the light-shielding mainboard 200 is processed using a special process to form a matte light-absorbing surface. Unlike ordinary smooth surfaces, the matte light-absorbing surface exhibits a finely textured surface with no specular reflection, specifically designed to absorb the strong light generated during laser obstacle removal operations. When the laser obstacle removal device is working, it emits a high-intensity laser, which produces strong reflected and scattered light after illuminating obstacles. This light shines onto the inner side of the light-shielding mainboard 200. Due to the rough surface structure of the matte light-absorbing surface, specular reflection does not occur after the light is irradiated; instead, multiple diffuse reflections occur within the gaps in the surface texture. During this process, the energy of the light is gradually absorbed, thereby significantly reducing the intensity of the reflected light and minimizing the leakage of strong light outwards. This design works in conjunction with the arc-shaped structure of the light-shielding main board 200 and the telescopic function of the light-shielding sub-board 210 to ensure that the matte light-absorbing surface can fully cover the area illuminated by light, absorb strong light to the maximum extent, and avoid strong light interfering with the operator. At the same time, it fits the overall light-shielding logic of the light-shielding component, achieving dual protection of "blocking + absorption" to ensure work safety.

[0031] Understandably, the matte light-absorbing surface on the inner side of the light-shielding mainboard 200 precisely addresses the technical pain point of existing light-shielding devices that can only block strong light but cannot effectively absorb it, leading to reflected light interfering with operation. Specifically: First, the matte light-absorbing surface efficiently absorbs the strong light generated during laser operations. Through its rough surface texture, it achieves multiple diffuse reflections and energy absorption of the light, significantly reducing the intensity of reflected light. This prevents strong light from reflecting from the inner side of the light-shielding mainboard 200 into the operator's field of vision, effectively protecting the operator's eyes and preventing eye damage from strong light. Simultaneously, it reduces strong light interference, improves visual clarity during operation, and ensures the accuracy of laser obstacle removal operations. Second, the matte light-absorbing surface eliminates the need for additional light-absorbing components; the light-absorbing function is achieved solely through surface treatment. This simplifies the structural design of the light-shielding mainboard 200, reduces manufacturing costs, and does not affect the overall strength and lifespan of the light-shielding mainboard 200. Furthermore, the matte light-absorbing surface has excellent wear resistance and stain resistance, making it suitable for complex outdoor operating environments. It is not easily affected by dust or minor scratches, ensuring long-term stable absorption of strong light. Compared to ordinary smooth-surfaced light shields, it has better light absorption and stronger protection, further improving the light shielding performance of the entire light shielding component, providing reliable safety for outdoor laser obstacle removal operations, and enhancing the practicality and reliability of the device.

[0032] Specifically, the gas spring telescopic rod 300 utilizes the sealed energy storage characteristics and force balance principle of high-pressure inert gas, combined with a pre-charged sealing structure design, to achieve stable self-locking positioning of the main light-shielding plate from 0-90°. The gas spring telescopic rod 300 employs a pre-charged sealing structure, providing excellent overall sealing performance and effectively preventing internal gas leakage. It is pre-filled with high-pressure inert gas, which is chemically stable, leak-proof, and unaffected by temperature, allowing for long-term stable operation without additional refilling. The high-pressure inert gas generates stable gas pressure within the sealed cavity, interacting with the piston structure inside the gas spring telescopic rod 300 to form an adjustable elastic support force. When adjusting the angle of the main light-shielding plate, the gas spring telescopic rod 300 extends and retracts axially as the plate rotates. This changes the gas pressure within the cavity. Once the target angle is reached, the gas pressure balances with the gravity of the main light-shielding plate and the force at the hinge point, achieving self-locking positioning. Meanwhile, by precisely designing the stroke and force parameters of the gas spring, the self-locking positioning range is controlled within 0-90°, adapting to the angle adjustment requirements of the main light-shielding plate. It works in conjunction with the hinge structure of the main light-shielding plate and the base body 100 to ensure that the main light-shielding plate can be stably fixed at any adjustment angle, providing reliable support for shading operations.

[0033] Understandably, the gas spring telescopic rod 300 employs a pre-charged sealed structure and is filled with high-pressure inert gas, precisely addressing the technical pain points of existing gas spring telescopic rods 300, such as the need for regular inflation, cumbersome maintenance, unstable positioning, and unsuitable angle range. Specifically: First, the pre-charged sealed structure combined with high-pressure inert gas eliminates the need for additional inflation, significantly reducing maintenance costs and operational complexity. This makes it suitable for the complex outdoor operating environment of laser obstacle clearing devices, allowing operators to achieve long-term stable use without carrying inflation equipment. Second, the chemically stable nature of inert gas is minimally affected by outdoor temperature, humidity, and other environmental factors. The sealed structure effectively prevents gas leakage, ensuring the long-term stability of the gas spring telescopic rod 300's telescopic and self-locking performance. This prevents the main light-blocking plate from loosening or failing to position due to gas leakage, ensuring operational safety. Furthermore, the precisely designed 0-90° self-locking positioning range perfectly adapts to the angle adjustment requirements of the main light-blocking plate. It allows for flexible adjustment of the main light-blocking plate to a suitable angle and stable self-locking based on the direction of sunlight during outdoor operations, eliminating the need for additional locking mechanisms and simplifying the operation process. Meanwhile, the elastic support force provided by the high-pressure inert gas is uniform and stable, which can effectively buffer the impact force of the main light shield's flipping, reduce component wear, extend the service life of the gas spring telescopic rod 300 and the main light shield, and further improve the reliability and practicality of the entire angle support assembly.

[0034] Specifically, the magnetic attraction component, based on the physical property of opposite poles of magnets attracting each other, combined with the uniform force design of the ring structure, achieves a tight attraction and fixation between the protective cover 500 and the base body 100. The magnetic attraction component is a second ring magnet 410, fixedly installed inside the protective assembly. Its installation position and size completely correspond to the first ring magnet 400 on the base body 100, and the two are arranged with opposite poles corresponding to each other; that is, the N pole of the first ring magnet 400 corresponds to the S pole of the second ring magnet 410, and vice versa. This is specifically designed to achieve a tight attraction between the protective cover 500 and the base body 100. According to the physical law of opposite poles attracting each other, the first ring magnet 400 and the second ring magnet 410, with their opposite poles, will generate a stable attractive force. The ring structure design ensures that the attractive force is evenly distributed across the entire attraction surface, avoiding gaps caused by uneven local force and ensuring a comprehensive and balanced attraction force. Meanwhile, the second annular magnet 410 precisely corresponds to the first annular magnet 400, which can guide the protective cover 500 to be quickly positioned and installed, so that the protective cover 500 fits tightly with the base body 100. Combined with the contour adaptation design of the protective cover 500, the stability of the attraction is further improved, and the protective cover 500 is reliably fixed, providing comprehensive protection for the light-shielding component and forming a collaborative working system with the overall magnetic attraction component and protective component.

[0035] Understandably, the magnetic mate employs a second annular magnet 410 with opposite poles to the first annular magnet 400. This specifically addresses the technical pain points of existing magnetic structures, such as loose engagement, inaccurate positioning, and easy detachment. Specifically: First, the first and second annular magnets 410 with opposite poles generate a stable and strong attraction force. Compared to magnets with the same poles or a single magnet, the engagement is more secure, effectively preventing the protective cover 500 from falling off due to vibration or collision during outdoor operations, ensuring the reliability of the protection and ensuring that the shading component is always in an effective protective state. Second, the annular structure distributes the attraction force evenly across the entire engagement surface, avoiding gaps caused by insufficient local attraction force. This ensures a tight fit between the protective cover 500 and the base body 100, preventing dust and debris from entering through gaps, further improving dustproof and scratch-proof protection. Furthermore, the second annular magnet 410 precisely corresponds to the first annular magnet 400, guiding the protective cover 500 to quick positioning and installation. This avoids problems such as inadequate protection and component wear caused by misalignment. Simultaneously, no additional fixing tools are required, allowing operators to quickly install and remove the protective cover 500, improving operational convenience. The overall structural design is simple and reliable, requiring no complex processing techniques, reducing manufacturing costs. The annular magnets are highly stable and have a long service life, making them suitable for complex outdoor operating environments. This further enhances the practicality and reliability of the entire magnetic and protective assembly, providing robust protection for the core components of the device.

[0036] Specifically, the mounting holes on the base body 100 are based on the mechanical fixing principle of bolt fastening, combined with a uniform force distribution design, to achieve a reliable connection between the base body 100 and the laser obstacle removal device host, providing a stable installation foundation for the entire light-shielding and protection device. At the rear end of the base body 100, several mounting holes are evenly distributed. The number, diameter, and spacing of these holes have been precisely calculated to perfectly match the pre-reserved installation positions on the laser obstacle removal device host, specifically designed for fixing the base body 100 to the laser obstacle removal device host using bolts. The core technical principle is as follows: the bolts pass through the mounting holes on the base body 100, forming a threaded engagement with the threaded holes on the laser obstacle removal device host. The tightening force of the threaded connection firmly fixes the base body 100 to the host. The evenly distributed design of the mounting holes ensures that the tightening force of the bolts is evenly distributed across the entire connection surface at the rear end of the base body 100, avoiding loosening or deformation of the base body due to localized force concentration, thus ensuring the stability of the connection. Meanwhile, the even distribution of mounting holes enables precise positioning of the base body 100 and the main unit, avoiding device offset caused by misalignment during installation, ensuring that subsequent components such as the light-shielding component and angle support component can accurately cooperate with the main unit, guaranteeing the normal operation of the entire device, and adapting to the use needs of laser obstacle clearing devices in complex outdoor operations.

[0037] Understandably, the evenly distributed mounting holes on the base body 100 precisely address the technical pain points of existing bases, such as insecure fixing, inaccurate positioning, and inconvenient assembly and disassembly. Specifically: First, the evenly distributed mounting holes at the rear end of the base body 100 ensure uniform bolt tightening force, effectively preventing deformation and loosening of the base body 100 due to localized stress concentration. This ensures a secure connection between the base body 100 and the laser obstacle clearing device host, maintaining stability even under vibration and collision conditions during outdoor operations. This provides a reliable installation foundation for the entire shading and protection device, guaranteeing the coordinated operation of all components. Second, the precise matching of the number and diameter of the mounting holes with the host's reserved positions guides the rapid positioning and installation of the base body 100, preventing device misalignment and ensuring that the shading components, protection components, and other parts accurately correspond to the host's operating position, improving the shading and protection effect. Furthermore, the device is secured by bolts passing through mounting holes, allowing for convenient assembly and disassembly. Operators can quickly install and remove the main body 100 using standard tools, facilitating maintenance, repair, and replacement, and meeting the convenience requirements of complex outdoor operations. The overall structural design is simple and reasonable, requiring no complex processing techniques, reducing manufacturing costs. The evenly distributed mounting holes offer strong adaptability, enabling compatibility with different models of laser obstacle clearing devices, further enhancing the device's versatility, practicality, and reliability.

[0038] In a specific embodiment of this application, the above steps are implemented in the following ways: In scenarios such as power line inspection and outdoor laser obstacle removal, after arriving at the work site with the laser obstacle removal device, the operator first uses bolts to precisely fix the base body 100 to the laser obstacle removal device host through the evenly distributed mounting holes at the rear end of the base body 100. This ensures that the device is firmly installed and accurately positioned, providing a stable foundation for the subsequent implementation of light-shielding and protection functions. Then, according to the angle and intensity of the laser reflected light at the site and the operational requirements, the operator manually flips the arc-shaped light-shielding main plate 200. Utilizing the telescopic characteristics of the two symmetrically arranged pre-charged sealed gas spring telescopic rods 300, the operator drives the light-shielding main plate 200 to rotate around the hinge shaft 220, adjusting it to a suitable light-shielding angle within the range of 0-90°. The high-pressure inert gas inside the gas spring telescopic rods 300 achieves self-locking, ensuring that the light-shielding main plate 200 is stable and does not loosen. Next, the operator uses their fingers to pull the protruding handle 270 at the outer end of the light-shielding sub-plate 210 to pull out both sides. The arc-shaped light-shielding sub-plate 210 allows it to slide smoothly along the damping plate slide rail 230 inside the light-shielding main plate 200 via the guide rail mating parts 250 on both sides until it forms a complete light-shielding surface with the light-shielding main plate 200, adapting to different light-shielding needs on site. At the same time, the matte light-absorbing surface on the inner side of the light-shielding main plate 200 efficiently absorbs the strong light generated by laser operation, avoiding light reflection that interferes with the working field of vision. After the operation is completed, the operator pushes the light-shielding sub-plate 210 back into the light-shielding main plate 200, flips the light-shielding main plate 200 to the retracted state, and then the protective cover 500 is attracted by the second annular magnet 410 on the inner side and the opposite pole of the first annular magnet 400 on the base body 100, so that the protective cover 500 fits tightly against the base body 100, completely covering the light-shielding component inside, achieving dustproof, scratch-proof, and impact-proof protection for the light-shielding component. The entire scene is easy to operate, adaptable to complex outdoor working environments, and fully realizes all the functions of this device.
