Technical Field
[0001] The present invention relates to the technical field of optical cable fusion splicing, and is an amplifying optical cable fusion splicing protection device. Background Art
[0002] As a core link in the construction and maintenance of optical communication networks, the quality and efficiency of optical cable fusion splicing directly affect the stability, bandwidth capacity, and operation and maintenance costs of communication systems. The signal loss is directly related to the transmission quality. If the single-fusion loss exceeds 0.05 dB, it will cause the attenuation of optical signals. Especially in long-distance backbone networks, the cumulative loss of multiple fusion points may lead to an increase in the bit error rate, video freezing, or even communication interruption.
[0003] In addition, the climate also poses a core challenge to fusion splicing. First, the climate conditions are harsh. In some areas, the winter temperature can reach -30°C, resulting in a decrease in the battery efficiency of the fusion splicer, shrinkage and jamming of mechanical components, and frozen fingers of operators, causing deformation of the fiber stripping and cutting actions. Second, strong wind and sand climates occur frequently. Wind and sand invade the inside of the fusion splicer, contaminating the V-groove and lens, greatly increasing the difficulty of cleaning the fiber end face, and increasing the fusion loss rate. In some areas, there will also be severe weather with instantaneous strong winds. During the operation process, the strong wind blows the unfixed optical fiber or the fusion splicer bracket, resulting in the offset of the fiber core.
[0004] When splicing outdoor optical cables, there are many problems such as dazzling reflection of equipment, difficulty in aligning the too-thin optical fiber, hand shaking at low temperature affecting the operation, cumbersome adjustment of the observation angle, and dust interference on windy days. Therefore, there is an urgent need for an amplifying optical cable fusion splicing protection device to solve the above technical problems. Summary of the Invention
[0005] The present invention provides an amplifying optical cable fusion splicing protection device, which overcomes the above-mentioned deficiencies of the prior art and can effectively solve the problems of dazzling reflection of equipment, difficulty in aligning the too-thin optical fiber, hand shaking at low temperature affecting the operation, cumbersome adjustment of the observation angle, and dust interference on windy days during outdoor optical cable fusion splicing.
[0006] The technical solution of the present invention is realized by the following measures: an amplifying optical cable fusion splicing protection device, including a cover body, a zoom mechanism, an angle adjustment mechanism, and a supplementary light mechanism; Among them, the zoom mechanism is arranged on the top of the cover body and is used for continuously zooming in and magnifying the optical cable fusion splicing part to assist in precise fusion splicing; Among them, the angle adjustment mechanism is arranged on the side of the cover body and below the zoom mechanism and is used for adjusting the tilt angle of the cover body to adapt to different operation perspectives; Among them, the supplementary light mechanism is arranged around the zoom mechanism and is fixedly connected to the zoom mechanism and is used for supplementary lighting in a dark environment and warming up in a cold environment to ensure operation accuracy.
[0007] The following is a further optimization and / or improvement of the above-mentioned technical solution of the invention: The above zoom mechanism may include two groups of plano-convex lenses, which are coaxially arranged along the optical axis direction. The distance between the two groups of plano-convex lenses is adjusted by adjusting the zoom adjustment knob sliding guide rail, so as to achieve continuous zooming.
[0008] The above angle adjustment mechanism may include four controllable angle hinges. The angle adjustment mechanism is connected to the zoom mechanism through the four controllable angle hinges to achieve the adjustment of the tilt angle.
[0009] The above fill light mechanism may include a light source control button and four fill lights. The light source control button is electrically connected to the fill lights and is used to control the switching of the fill lights between the lighting gear and the warming gear.
[0010] The above plano-convex lenses may adopt low-dispersion glass lenses, and the lens surfaces are coated with broadband AR films.
[0011] The above low-dispersion glass lenses may be of FK61 material, and the wavelength range of the broadband AR film is 400 - 1600 nm.
[0012] The above zoom adjustment knob may be connected to the sliding guide rail through screw drive to adjust the distance between the two groups of plano-convex lenses.
[0013] The above four controllable angle hinges may be evenly distributed at the connection part between the angle adjustment mechanism and the zoom mechanism, and the rotation angle range of each hinge is at least 180°.
[0014] The above fill lights may be LED heating linear fill lights.
[0015] The above cover body may adopt transparent acrylic material, with a soft rubber sealing ring at the bottom and coated with an anti-UV coating.
[0016] Through the collaborative action of various mechanisms, the present invention has remarkable effects in improving welding accuracy, adapting to complex environments, optimizing the operation experience, etc. The zoom mechanism adopts two groups of plano-convex lenses in cooperation with an adjustment knob and a sliding guide rail to achieve continuous zooming from 5 to 15 times. The low-dispersion glass lens and broadband AR film reduce dispersion and improve light transmittance, making up for the limitations of the operator's naked-eye observation, enabling the operator to clearly observe the welding part and operate precisely, significantly improving the accuracy of optical fiber welding; the adjustment knob driven by screw thread transmission precisely controls the lens spacing to ensure stable zooming and further assist precise operation. The LED heating linear supplementary light of the supplementary light mechanism can switch between the lighting and heating gears. When it is in the lighting gear, it solves the problem of blurred core edges caused by insufficient outdoor light or backlight, ensuring that the core end face is clearly visible; when it is in the heating gear, it generates heat to relieve the stiffness of the operator's hands in winter; the soft rubber seal ring and anti-UV coating at the bottom of the transparent acrylic cover form a sealed windproof structure, which can prevent the wind from blowing the optical fiber or introducing dust, reducing the outdoor operation burden increased by climatic reasons, and enabling the device to work stably in various outdoor complex environments. The angle adjustment mechanism adjusts the tilt angle of the cover through four controllable-angle hinges, providing direct-view and side-view auxiliary perspectives, reducing the visual blind area, and adapting to the observation habits and postures of different operators; moreover, the device can be folded and stored, is light and easy to carry, can adapt to various operation scenarios, and greatly improves the work efficiency of maintenance personnel.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The present invention is not limited by the following embodiments, and the specific implementation manners can be determined according to the technical solutions of the present invention and the actual situation.
[0022] The following further describes the present invention in conjunction with embodiments: Embodiment 1: As shown in the Figure 1 , 2, as shown in FIGS. 3, the amplifying optical cable fusion splicing protection device includes a cover body, a zoom mechanism 4, an angle adjustment mechanism 5 and a supplementary lighting mechanism. Among them, the zoom mechanism 4 is arranged on the top of the cover body and is used for continuously zooming in and magnifying the optical cable fusion splicing part to assist in precise fusion splicing. Among them, the angle adjustment mechanism 5 is arranged on the side of the cover body and below the zoom mechanism 4 and is used for adjusting the tilt angle of the cover body to adapt to different operation perspectives. Among them, the supplementary lighting mechanism is arranged around the zoom mechanism 4 and is fixedly connected to the zoom mechanism 4 and is used for supplementary lighting in a dark environment and heating in a cold environment to ensure operation accuracy. When performing optical cable fusion splicing operations, the operator adjusts the magnification according to actual needs by operating the zoom mechanism 4 so as to clearly observe the fusion splicing part; uses the angle adjustment mechanism 5 to adjust the tilt angle of the cover body to find the best observation perspective; turns on the lighting function of the supplementary lighting mechanism in a dark environment and turns on the heating function in a cold environment. The present invention realizes the assistance for optical cable fusion splicing operations in various environments, improves the precision of fusion splicing, adapts to the operation habits of different operators, improves work efficiency, and reduces the interference of environmental factors on fusion splicing work.
[0023] In an embodiment of the present invention, the cover body is made of transparent acrylic material, with a rubber sealing ring at the bottom and coated with an anti-UV coating. The transparent acrylic material ensures that the operator can observe the internal fusion splicing situation through the cover body; the rubber sealing ring at the bottom fits on the fusion splicer to prevent external dust and air from entering; the anti-UV coating absorbs or reflects ultraviolet rays, reducing the impact of ultraviolet rays on the internal components of the device and the operator. It effectively prevents dust from entering and affecting the fusion splicing quality, and avoids the fusion splicing error caused by the wind blowing the optical fiber; the anti-UV coating protects the device and the operator, extends the service life of the device, and improves the applicability and reliability of the device in outdoor environments. The whole cover body is coated with an anti-UV coating to reduce screen reflection, and is connected to the double-lens group zoom system by four controllable-angle hinges 9. During use, the tilt angle of the protective cover can be adjusted, which is more convenient for maintenance personnel to observe the operation from different angles. Due to the hinge connection, the whole device can be folded and stored, and is light and portable.
[0024] In an embodiment of the present invention, a charging port 6 can also be provided. The four LED heating linear supplementary lights in the supplementary lighting mechanism require power support when working in the lighting gear and the heating gear. After the charging port 6 is connected to an external power source, it can store electrical energy in the built-in battery of the device or directly supply power to the supplementary lights 3, so that the supplementary lights 3 continuously provide stable lighting in a dark environment, ensuring that the operator can clearly observe the optical cable fusion splicing part; in a cold environment, it can also ensure that the supplementary lights 3 are stably switched to the heating gear to assist in keeping the operator's hands warm and avoiding affecting the operation accuracy due to hand hypothermia.
[0025] The device is a foldable "匚"-shaped structure, with a dual-lens group zoom system and four LED heated linear fill lights on the top. The zoom system can adjust the lens spacing by changing the sliding guide rail through the zoom adjustment knob 8 to achieve 5-15 times continuous zoom. The LED heated linear fill lights can be controlled by the light source control button 7, with the first gear for lighting and the second gear for heating. The side is an angle adjustment bracket, which is connected to the dual-lens group zoom system through four controllable angle hinges 9. The tilt angle of the protective cover can be adjusted during use, and it can be folded and stored, making it light and easy to carry.
[0026] When in use, the device can be placed on the fiber splicing machine according to daily operations, and the magnification can be controlled by adjusting the zoom adjustment knob 8. The tilt angle of the protective cover can be adjusted by adjusting the controllable angle hinge 9 to facilitate the operator to align the optical fiber in the fiber splicing machine. At the same time, the device can prevent wind from blowing the optical fiber or introducing dust in an outdoor environment, and can provide supplementary lighting for the operation process in a dark environment. In a cold environment, the LED light source can be adjusted to the 2nd heating gear to assist the operator in keeping his hands warm, thereby alleviating the problem of stiff hands caused by hypothermia and trembling that causes the optical fiber to be unable to be aligned, affecting the operation and maintenance time and efficiency.
[0027] The present invention can significantly improve the efficiency and accuracy of optical fiber fusion splicing. First, visual enhancement. The magnifying glass design adopts a magnifying glass module with an adjustable magnification (such as 5-10 times) to make up for the limitations of the operator's naked eye observation. At the same time, the adjustable angle bracket can provide auxiliary viewing angles for direct and lateral observation, reducing visual blind spots. Second, the LED ring fill light integrates cold and hot light source LED lamps on the edge of the cover to solve the problem of blurred fiber core edges caused by insufficient outdoor light or backlight, ensuring that the fiber core end face is clearly visible. The hot light source LED lamp can generate a certain amount of heat to relieve the stiffness of the operator's hands in winter. Third, the enclosed windproof structure can prevent the wind from blowing the optical fiber or introducing dust, reducing the burden of outdoor operations caused by climate reasons. The present invention can be folded and stored, is light and easy to carry, can adapt to a variety of operating scenarios, and greatly improves the work efficiency of maintenance personnel.
[0028] Embodiment 2: As attached Figure 1 , 2, as shown in FIGS. 3, the zoom mechanism 4 of the amplified optical cable fusion protection device includes two plano-convex lenses. The two plano-convex lenses are coaxially arranged along the optical axis direction. The distance between the two plano-convex lenses is adjusted by a zoom adjustment knob 8 to control a sliding guide rail, so as to achieve continuous zooming. The operator rotates the zoom adjustment knob 8, and the zoom adjustment knob 8 drives the sliding guide rail to move, changing the distance between the two plano-convex lenses, and further changing the refraction path of light, so as to achieve continuous magnification or reduction of the observed object. Compared with the traditional fixed magnification or jump zooming method, continuous zooming can meet more refined observation needs, enabling the operator to flexibly adjust the magnification according to the specific situation of fusion splicing, more accurately observe the fiber butt joint situation, and improve the fusion splicing quality.
[0029] In the embodiment of the present invention, the plano-convex lens adopts a low-dispersion glass lens, and the lens surface is coated with a broadband AR film. The low-dispersion glass lens reduces the refraction difference of different color lights when light passes through the lens, reducing the dispersion phenomenon; the broadband AR film reduces the reflected light on the lens surface, allowing more light to pass through the lens. It improves the clarity and quality of imaging, reduces image blurring and color distortion caused by dispersion, and at the same time increases the light transmittance, making the observed fusion splicing part clearer, which helps to improve the accuracy of fusion splicing operation.
[0030] In the embodiment of the present invention, the low-dispersion glass lens is made of FK61 material, and the wavelength range of the broadband AR film is 400 - 1600 nm. The low-dispersion glass lens made of FK61 material has specific optical properties, effectively suppressing dispersion in a relatively wide wavelength range; the broadband AR film with a wavelength range of 400 - 1600 nm specifically reduces the reflection of light in this wavelength band. Further optimizing the optical performance of the lens, within the common optical communication wavelength band, it minimizes the influence of dispersion and reflection, ensuring that a clear and real image can be obtained even at high magnification, improving the observation effect and fusion splicing accuracy. The zoom mechanism 4 adopts two plano-convex lenses (diameter 50 mm), and the distance between the lenses is adjusted by adjusting the sliding guide rail with a knob to achieve 5 - 15 times continuous zooming, which is more adaptable to complex observation needs than the traditional multi-lens rotation switching. At the same time, considering that there may be direct sunlight reflection during outdoor work, an achromatic design and anti-reflection treatment are performed on this system. FK61 low-dispersion glass lenses are used to reduce the dispersion phenomenon at high magnification, and the lens surface is coated with a broadband AR film (400 - 1600 nm), and the light transmittance can reach more than 98%.
[0031] In the embodiment of the present invention, the zoom adjustment knob 8 is connected to the sliding guide rail through a threaded transmission to adjust the spacing between the two sets of plano-convex lenses. When the operator turns the adjustment knob, the threads on the knob cooperate with the threads on the sliding guide rail to convert the rotary motion of the knob into the linear motion of the sliding guide rail, thereby achieving precise adjustment of the spacing between the two sets of plano-convex lenses. The threaded transmission has the characteristics of high transmission accuracy and good stability, and can achieve fine adjustment of the lens spacing, ensure the stability and accuracy of the zoom process, and provide reliable guarantee for precise observation.
[0032] Embodiment 3: As attached Figure 1 , 2 As shown in Figure 3, the angle adjustment mechanism 5 of the magnified optical cable fusion protection device includes four controllable angle hinges 9, and the angle adjustment mechanism 5 is connected to the zoom mechanism 4 through the four controllable angle hinges 9 to adjust the tilt angle. The operator manually moves the angle adjustment mechanism 5, and the controllable angle hinge 9 rotates accordingly, driving the entire angle adjustment mechanism 5 and the cover body to change the tilt angle around the rotating axis of the hinge, thereby changing the viewing angle. It is convenient for operators to observe the fusion part from different angles, avoid operating errors caused by limited viewing angles, improve the convenience and flexibility of operation, and adapt to various complex operating environments.
[0033] In the embodiment of the present invention, four controllable angle hinges 9 are evenly distributed at the connection between the angle adjustment mechanism 5 and the zoom mechanism 4, and the rotation angle range of each hinge is at least 180°. Since the four hinges are evenly distributed, when adjusting the angle, each hinge rotates synchronously or asynchronously to jointly change the tilt angle of the angle adjustment mechanism 5, and the 180° rotation range provides a larger adjustment space. The even distribution ensures the stability and balance of the angle adjustment, and the large angle rotation range allows the operator to adjust the observation angle more freely, meeting the observation needs in various complex operation scenarios.
[0034] Embodiment 4: As attached Figure 1 , 2 As shown in Figure 3, the fill light mechanism of the amplified optical cable welding protection device includes a light source control button 7 and four fill light lamps 3. The light source control button 7 is electrically connected to the fill light lamps 3 to control the fill light lamps 3 to switch between the lighting gear and the heating gear. When the light source control button 7 is pressed to switch to the lighting gear, the circuit is connected, and the fill light lamps 3 emit light at a specific power to provide lighting light; when switching to the heating gear, the power of the fill light lamps 3 increases to generate more heat. Sufficient lighting is provided in dark environments to ensure that the operator can clearly see the welding part; in cold environments, the operator's hands are kept warm to prevent the welding accuracy from being affected by cold and trembling hands, thereby improving the applicability of the device in different environments.
[0035] In the embodiment of the present invention, the fill light 3 is an LED heating linear fill light. The LED heating linear fill light utilizes the LED light-emitting principle. In the lighting mode, the LED emits light at a low power to provide illumination; in the heating mode, the current is increased to make the LED generate more heat to achieve the heating function. Compared with the ordinary fill light 3, the LED heating linear fill light has a more integrated function, which can not only meet the lighting requirements but also assist in heating in a cold environment, simplifies the device structure, and improves the practicability and functionality of the device.
[0036] The above technical features constitute the embodiment of the present invention, which has strong adaptability and implementation effects. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
