Description

Technical Field

[0001] The present invention specifically relates to an optical fiber amplifier and method, and relates to the technical field of communication accessories. Background Art

[0002] With the rapid development of optical fiber communication technology, optical fiber amplifiers are key signal enhancement devices, and their performance and installation methods are crucial to the stability and efficiency of communication systems. However, existing optical fiber amplifiers have exposed some significant limitations in practical applications. Traditional optical fiber amplifiers often require complex fixtures and a long installation time during installation, which not only increases the difficulty of on-site deployment, reduces installation efficiency and flexibility of use, but also limits the response speed to emergency communication needs, making it difficult to meet the requirements of rapid deployment scenarios;

[0003] In addition, quick and stable installation is the basis for ensuring the long-term reliable operation of the fiber optic amplifier. However, the current installation method often causes problems such as loose fixation and unstable connection, which makes the equipment susceptible to external vibrations during operation, affecting the signal transmission quality and reducing the overall stability and reliability of the system. Especially in complex usage environments, such as earthquakes, bumps or improper human operation layout, the fiber optic amplifier is extremely susceptible to physical damage and affects its normal operation. Therefore, how to design a fiber optic amplifier that is easy to install, flexible to use, stable in structure and has excellent shock absorption, buffering and protection has become a key technical problem that needs to be urgently solved in the current fiber optic communication field.

[0004] In summary, existing fiber optic amplifiers have obvious deficiencies in rapid deployment and installation, ease of use, installation stability, and shock absorption, buffering, and protection. It is urgent to provide a fiber optic amplifier and method to overcome these challenges and promote the development of fiber optic technology in a more efficient, stable, and safer direction. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a fiber amplifier and method to solve the problems mentioned in the above background technology.

[0006] In order to achieve the above object, the present invention is implemented by the following technical solution: an optical fiber amplifier, comprising an amplifier body, a transparent protective cover is hingedly connected to the upper side of the amplifier body, and one end of the transparent protective cover is buckled and connected to the upper side of the amplifier body;

[0007] Two L-shaped card seats are used to relatively press the two sides of the amplifier body, and elastic top plates are arranged on opposite sides of the two L-shaped card seats to adaptively press and fix the two sides of the amplifier body;

[0008] A protection frame, used for mounting the two L-shaped holders, wherein the middle of the protection frame is provided with an adjustment component for adjusting the relative displacement of the L-shaped holders;

[0009] An electromagnetic suction cup is connected to the bottom of the protective frame, a magnet is locked on the upper side of the electromagnetic suction cup, and a metal magnetic block is locked on the upper side of the magnet for supporting the amplifier body. The magnets are magnetically adsorbed to the metal magnetic block and the electromagnetic suction cup respectively and allow the metal magnetic block and the electromagnetic suction cup to synchronously generate a constant magnetic field, and the metal magnetic block is magnetically adsorbed to the bottom of the amplifier body.

[0010] Based on the above technical solution, a battery box and a control switch which are interconnected are embedded and installed on the upper side of the L-shaped card holder, and the control switch is electrically connected to the electromagnetic suction cup.

[0011] Based on the above technical solution, an LED light board is installed on the top of the L-shaped card seat through a damping shaft. The LED light board corresponds to both sides of the transparent protective cover, and the LED light board covers the battery box and the top of the control switch.

[0012] Based on the above technical solution, the adjustment component includes a guide rod, a first screw and a second screw rotatably installed in the middle of the protective frame. The guide rod passes through the metal magnet and the middle of the L-shaped socket. The first screw and the second screw are arranged opposite to each other and are respectively rotatably installed on both sides of the metal magnet to keep the position of the metal magnet unchanged.

[0013] Based on the above technical solution, the first screw and the second screw are provided with a rotating protrusion at one opposite end, and are rotatably clamped on both sides of the metal magnetic block through the rotating protrusion. The other end of the first screw and the second screw is installed with an adjustment knob, and the adjustment knob is arranged on the outside of the protective frame.

[0014] Based on the above technical solution, movable grooves for the elastic top plate to slide and adapt are opened on opposite sides of the two L-shaped sockets, and multiple springs are installed inside the movable grooves, which are elastically connected to the elastic top plate through the springs.

[0015] Based on the above technical solution, an inner slot is opened in the middle of the lower side of the L-shaped card seat, and the inner slot is adapted to the size of the metal magnet, and an iron sheet is provided on the inner side of the inner slot to fit in contact with the surface of the metal magnet. When the two L-shaped card seats are clamped relative to each other, the metal magnet is clamped in the inner slot, and the upper side of the metal magnet is flush with the upper side of the turning horizontal plate of the L-shaped card seat, and the metal magnet is located below the elastic top plate.

[0016] Based on the above technical solution, Z-shaped connecting pieces are installed at the four corners of the protective frame respectively. The bottom surface of the Z-shaped connecting piece is flush with the bottom surface of the electromagnetic suction cup, and the Z-shaped connecting piece is provided with a mounting hole. A sliding groove is provided at the bottom of the protective frame, and the electromagnetic suction cup is slid into one side of the sliding groove and fastened by screws.

[0017] Based on the above technical solution, an iron block is installed at the bottom of the amplifier body, which is magnetically connected to the metal magnetic block. A layer of rubber gasket is compounded on the upper side of the metal magnetic block and the edge of the opposite side of the L-shaped socket.

[0018] Also included is a method for using the optical fiber amplifier:

[0019] When the electromagnetic suction cup is not powered on, the magnetism of the magnet is used to act on the metal magnetic block and the electromagnetic suction cup respectively, and the metal magnetic block and the electromagnetic suction cup synchronously generate a relatively stable weak magnetic field. At this time, the amplifier body can be adsorbed and placed on the metal magnetic block for initial stability, and then the relative displacement of the two L-shaped holders is adjusted by the adjustment component, so that the elastic top plates on the opposite sides of the two L-shaped holders can be elastically pressed against the amplifier body for elastic fixation and buffering. At this time, a strong magnetic field is formed by energizing the electromagnetic suction cup, thereby enhancing the magnetic connection between the magnet and the metal magnetic block, and improving the magnetic connection between the metal magnetic block and the amplifier body. The electromagnetic suction cup after power-on can also be used to quickly adsorb and fix it on an external designated metal workstation.

[0020] By adopting the above technical solution, the present invention has the following advantages:

[0021] The invention has a simple and ingenious structure and is convenient and flexible to use. The optical fiber amplifier uses a unique electromagnetic suction cup design and a magnetic adsorption effect of a metal magnetic block. When the power is not turned on, the magnetism of the magnet can be used to initially stabilize the amplifier body and allow the electromagnetic suction cup to be magnetically attracted to a specified position. Compared with the traditional fixing method, it avoids long-term installation and debugging, and greatly improves the on-site operation efficiency. The strong magnetic field after the electromagnetic suction cup is powered on can significantly enhance the magnetic connection between the metal magnetic block and the amplifier body, ensuring the stability of the equipment in adverse environments such as vibration. That is, the combination of the constant magnetic field of the magnet and the controllable magnetic field of the electromagnetic suction cup can be used to effectively control the size of the adsorption force, which not only ensures the stability of the structure, but also provides flexible operability, and can be used for different complex environments.

[0022] The magnetic connection between the electromagnetic suction cup and the metal magnetic block not only ensures the stable adsorption of the amplifier body, but also can be quickly and strongly adsorbed and fixed on the designated metal workstation, realizing fast and stable positioning and deployment of the equipment, greatly improving work efficiency, especially suitable for emergency communication or rapid response scenarios. At the same time, with the elastic fixation and buffering of the L-shaped card holder and the elastic top plate, it not only improves the stability of the amplifier body installation, but also effectively reduces shock, protects the optical fiber amplifier from physical damage, and extends the service life of the equipment;

[0023] In addition, the adjustment component arranged in the protection frame can flexibly adjust the relative displacement of the two L-shaped holders, so that the optical fiber amplifier can adapt to amplifier bodies of different sizes, thereby improving the versatility and adaptability of the equipment. At the same time, combined with the elastic effect of the elastic top plate, the fixing process has a certain buffering effect, thus avoiding the damage that may be caused by hard contact, and ensuring the stable operation of the optical fiber amplifier in various environments.

[0024] The battery box and control switch are integrated on the two L-shaped card holders to realize self-power management, so that the LED light board and the electromagnetic suction cup can operate independently without external power supply. The electrical connection between the two control switches and the electromagnetic suction cup ensures the effective distribution and control of energy. If one of the battery box and the control switch fails, the other card holders can still control the electromagnetic suction cup to ensure the normal operation and safety of the equipment. Of course, users can also choose to activate a single or multiple electromagnetic suction cups as needed, which is very useful when the optical fiber amplifier needs to be adsorbed or released at a specific position. It is easier to maintain and replace batteries or control switches without interrupting the operation of the entire equipment.

[0025] The rotation adjustment setting of the LED light panel not only provides necessary lighting assistance, but also cleverly shields and protects the battery box and control switch, maintaining the overall aesthetics while enhancing practicality.

[0026] The inner slot in the middle of the lower side of the L-shaped card holder is precisely matched to the size of the metal magnetic block, ensuring that the metal magnetic block can be in close contact with the inner slot when it is clamped, forming a stable support structure, ensuring the stability of the placement of the amplifier body, and when the two L-shaped card holders are clamped relative to each other, the metal magnetic block not only supports the amplifier body, but also closely adsorbs with the inner slot iron sheet of the L-shaped card holder through magnetic attraction, further improving the structural stability of the L-shaped card holder, cleverly utilizing the physical properties of magnetic attraction, not only enhancing the supporting effect of the metal magnetic block on the amplifier body, but also increasing the rigidity and external force resistance of the overall structure through adsorption with the L-shaped card holder;

[0027] At the same time, an iron block is installed at the bottom of the amplifier body to form a stable magnetic connection with the metal magnet block to enhance the adsorption force. At the same time, the application of rubber gasket not only improves the friction coefficient of the contact surface to prevent tiny movements, but also plays a shock-absorbing effect, fully protecting the core part of the fiber optic amplifier from external interference.

DETAILED DESCRIPTION

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] like Figure 1-10As shown, the present invention provides a technical solution of an optical fiber amplifier, including an amplifier body 1, a transparent protective cover 2 is hingedly connected to the upper side of the amplifier body 1, and one end of the transparent protective cover 2 is buckled and connected to the upper side of the amplifier body 1 for dust prevention, accidental touch prevention, etc., two L-shaped card seats 4 are used to relatively press the two sides of the amplifier body 1, specifically, the two L-shaped card seats 4 are provided with elastic top plates 41 on the opposite sides to be adaptively pressed and fixed to the two sides of the amplifier body 1, so as to ensure that the equipment is accurately fixed during the installation process, and to avoid loosening or displacement caused by improper installation, and the two L-shaped card seats 4 are provided with movable grooves 42 on the opposite sides for the elastic top plates 41 to adapt and slide, and a plurality of springs 43 are installed inside the movable grooves 42, and the springs 43 and the elastic top plates 41 are elastically fixed. The movable groove 42 provides a sliding space for the elastic top plate 41 to ensure that it can move smoothly under the action of the spring 43. The spring 43 serves as a connecting medium between the elastic top plate 41 and the movable groove 42. Through its telescopic characteristics, it provides a dynamic buffer mechanism for the amplifier body 1. When the elastic top plate 41 is subjected to force, the elastic deformation of the spring 43 can absorb and disperse the impact force, reduce hard contact, and protect the amplifier body 1 from damage while playing a clamping role. The combination of the elastic top plate 41 and the spring 43 not only provides a stable support for the amplifier body 1, but also has a certain degree of flexibility. With the use of the adjustment component 7 of the L-shaped holder 4, it can adapt to different sizes of the amplifier body 1, ensuring the applicability and stability of the installation.

[0042] In this embodiment, the protection frame 3 is used to install two L-shaped holders 4. An adjustment component 7 for adjusting the relative displacement of the L-shaped holder 4 is provided in the middle of the protection frame 3. The adjustment component 7 includes a guide rod 71, a first screw rod 72 and a second screw rod 73 rotatably installed in the middle of the protection frame 3. The guide rod 71 passes through the metal magnetic block 8 and the middle of the L-shaped holder 4. The guide rod 71 mainly plays the role of guiding and supporting, ensuring the precise positioning of the middle of the L-shaped holder 4 during the adjustment process. The first screw rod 72 and the second screw rod 73 are relatively arranged and rotatably installed on both sides of the metal magnetic block 8, respectively. Through their own rotation, they drive the L-shaped holder 4 matched therewith to move along the axial direction of the guide rod 71, and in this way, the first screw rod 72 and the second screw rod 73 are relatively arranged and rotatably installed on both sides of the metal magnetic block 8, respectively. When the two screws 73 rotate, the position of the metal magnetic block 8 can be kept stable and connected to the amplifier body 1, and the first screw 72 and the second screw 73 are provided with a rotating protrusion 75 at the opposite end, and the rotating protrusion 75 is rotatably clamped on both sides of the metal magnetic block 8 to prevent the first screw 72 and the second screw 73 from easily detaching from the metal magnetic block 8. The other end of the first screw 72 and the second screw 73 is installed with an adjusting knob 74, and the adjusting knob 74 is arranged on the outside of the protective frame 3. The first screw 72 and the second screw 73 are driven to rotate by the two adjusting knobs 74, and the left and right movable displacements of the two L-shaped sockets 4 can be adjusted and controlled respectively, so as to adapt to the close contact with both sides of the amplifier body 1, and the use is simple and flexible.

[0043] The bottom of the protective frame 3 is connected to an electromagnetic suction cup 6, and a magnet 9 is locked on the upper side of the electromagnetic suction cup 6, and a metal magnetic block 8 is locked on the upper side of the magnet 9 for supporting and placing the amplifier body 1. The magnetism of the magnet 9 can be used to initially stabilize the amplifier body 1 and allow the electromagnetic suction cup 6 to be magnetically sucked at a specified position. Compared with the traditional fixing method, it avoids long-term installation and debugging, greatly improves the on-site operation efficiency, and is also convenient for the later debugging of the position of the entire optical fiber amplifier. The magnet 9 is magnetically absorbed by the metal magnetic block 8 and the electromagnetic suction cup 6 respectively, and the metal magnetic block 8 and the electromagnetic suction cup 6 synchronously generate a constant magnetic field. The metal magnetic block 8 is magnetically absorbed by the bottom of the amplifier body 1, and the electromagnetic suction cup 6 after power-on generates a strong magnetic field, which enhances the metal magnetic block 8 and the amplifier body. The magnetic connection of the body 1 ensures the stability of the equipment in adverse environments, that is, it utilizes the combination of the constant magnetic field of the magnet 9 and the controllable magnetic field of the electromagnetic suction cup 6, which can effectively control the size of the adsorption force, which not only ensures the stability of the structure, but also provides flexible operability. It can be adsorbed on a metal workstation that can be magnetized, and realizes fast and stable positioning and deployment of the equipment, greatly improving work efficiency. It is especially suitable for emergency communications or rapid response scenarios, and can be used for different complex environments. While having strong and weak magnetism, it can cooperate with the elastic fixation and buffering of the L-shaped card seat 4 and the elastic top plate 41, thereby improving the stability of the installation of the amplifier body 1, and effectively reducing shock, protecting the optical fiber amplifier from physical damage, and extending the service life of the equipment.

[0044] In the above technical solution, the upper sides of the two L-shaped card holders 4 are embedded with interconnected battery boxes 10 and control switches 11, and the control switch 11 is electrically connected to the electromagnetic suction cup 6. The L-shaped card holder 4 integrates the battery box 10 and the control switch 11 to achieve self-power supply and adapt to the environment without external power supply. The two control switches 11 are electrically connected to the electromagnetic suction cup 6 respectively. If one of the battery boxes 10 and the control switch 11 fails, the other card holders can still control the electromagnetic suction cup 6, ensuring the normal operation and safety of the equipment. Of course, the user can also select a single or multiple control switches 11 to control the electromagnetic suction cup 6 as needed, which is very useful when the optical fiber amplifier needs to be adsorbed or released at a specific position. It is simpler to maintain and replace the battery or control switch 11 without interrupting the operation of the entire device, ensuring the effective distribution and control of energy, and enhancing the stability and safety of the equipment operation.

[0045] Furthermore, it is further provided that an LED light board 5 is installed on the top of the L-shaped card seat 4 through a damping shaft, and the LED light board 5 corresponds to both sides of the transparent protective cover 2, and the LED light board 5 covers the battery box 10 and the control switch 11. The LED light board 5 provides lighting assistance and at the same time plays a role in shielding the battery box 10 and the control switch 11, maintaining the overall beauty and practicality, and the two LED light boards 5 are relatively arranged, and can be rotated to different angles according to the use requirements, which is simple and convenient to use;

[0046] In this embodiment, an inner slot 44 is provided in the middle of the lower side of the L-shaped card seat 4, and the inner slot 44 is adapted to the size of the metal magnetic block 8. When the two L-shaped card seats 4 are clamped relative to each other, the accurate alignment and stable clamping of the metal magnetic block 8 during the equipment assembly process are ensured, thereby improving the structural stability of the L-shaped card seat 4, and making the upper side of the metal magnetic block 8 and the upper side of the turning cross plate of the L-shaped card seat 4 level, which can play a synchronous support effect, and an iron sheet is provided on the inner side of the inner slot 44 to fit and contact with the surface of the metal magnetic block 8. This detail processing, combined with the flat placement of the metal magnetic block 8, not only saves space The metal magnetic block 8 is located below the elastic top plate 41 to avoid mutual influence therewith. When the two L-shaped holders 4 are clamped relative to each other, the metal magnetic block 8 not only supports the amplifier body 1, but also is tightly adsorbed with the inner card slot 44 iron sheet of the L-shaped holder 4 through magnetic attraction, further improving the structural stability of the L-shaped holder 4. The physical properties of the magnetic attraction force are cleverly utilized, which not only enhances the supporting effect of the metal magnetic block 8 on the amplifier body 1, but also increases the rigidity and external force resistance of the overall structure through adsorption with the L-shaped holder 4.

[0047] In this embodiment, the four corners of the protection frame 3 are respectively installed with Z-shaped connecting pieces 31, the bottom surface of the Z-shaped connecting piece 31 is flush with the bottom surface of the electromagnetic suction cup 6, and the Z-shaped connecting piece 31 is provided with a mounting hole, and a sliding slot 32 is provided at the bottom of the protection frame 3. The electromagnetic suction cup 6 is slidably embedded from one side of the sliding slot 32 and fastened by screws. When the electromagnetic suction cup 6 is not powered on, the Z-shaped connecting piece 31 mainly utilizes the constant magnetic field of the magnet 9 to make the electromagnetic suction cup 6 produce a magnetic suction effect. At this time, the electromagnetic suction cup 6 can adjust the magnetically attracted position to facilitate the alignment and locking of the mounting hole of the Z-shaped connecting piece 31;

[0048] In addition, an iron block 12 is installed at the bottom of the amplifier body 1, and the iron block 12 is magnetically connected to the metal magnetic block 8 to form a stable magnetic connection with the metal magnetic block 8 to enhance the adsorption force. At the same time, a layer of rubber gasket is compounded on the upper side of the metal magnetic block 8 and the edge of the opposite side of the L-shaped socket 4. Under the action of the rubber gasket, not only the friction coefficient of the contact surface is improved to prevent small movements, but also the shock-absorbing effect is exerted, thereby fully protecting the core part of the optical fiber amplifier from external interference.

[0049] The present invention also includes a specific method for using the optical fiber amplifier:

[0050] In the present invention, when the electromagnetic suction cup 6 is not powered, the magnetism of the magnet 9 is used to act on the metal magnetic block 8 and the electromagnetic suction cup 6 respectively, and the metal magnetic block 8 and the electromagnetic suction cup 6 synchronously generate a relatively stable weak magnetic field. At this time, the amplifier body 1 can be adsorbed and placed on the metal magnetic block 8 for preliminary stabilization, and then the adjustment knobs 74 of the two adjustment components 7 are rotated respectively, so that the first screw rod 72 and the second screw rod 73 respectively thread-drive the two L-shaped holders 4 to move relative to each other along the guide rod 71, so that the elastic top plates 41 on the opposite sides of the two L-shaped holders 4 can be elastically pressed against the amplifier body 1 by the action of the spring 43 to fix it, and the lower side horizontal plate of the L-shaped holder 4 is also located at the lower side of the amplifier body 1 at this time. Together with the metal magnetic block 8, the elastic top plate 41 slides along the inner side of the movable groove 42. The elastic fixation has a certain buffering and shock-absorbing effect. Of course, in this process, the L-shaped holder 4 can also be continuously displaced relatively according to the use requirements until the rubber gasket on the opposite side edge of the L-shaped holder 4 is pressed against the amplifier body 1, so that the amplifier body 1 is clamped and fixed for the second time, thereby greatly improving its stability. At this time, the entire optical fiber amplifier can be placed in an external position that can be magnetically attracted, and the relatively stable magnetic field of the magnet 9 is used to act on the unpowered electromagnetic suction cup 6, so that the electromagnetic suction cup 6 can be temporarily adsorbed and installed at the specified position. At this time, the magnetic force can move the entire optical fiber amplifier for adjustment. The position of the joint is convenient for the later alignment of the mounting hole of the Z-shaped connecting piece 31 and the screw fastening installation, so that the L-shaped holder 4 and the two L-shaped holders 4 can fix and support the amplifier body 1; then, by opening the LED light board 5 of one or two L-shaped holders 4, the control switch 11 is exposed, and the opening and closing of the LED light board 5 are controlled as needed, and the rotation angle of the LED light board 5 is adjusted to facilitate the lighting of the amplifier body 1 in an environment with low brightness. The buttons of the control panel on the upper side of the amplifier body 1 and the control switch 11 of the L-shaped holder 4 are controlled by the control switch 11 to form a strong magnetic field, thereby enhancing the magnetic field of the magnet 9 and the metal magnetic block 8. The electromagnetic suction cup 6 after being energized can be used to quickly absorb and fix it on the external designated metal workstation, greatly improving the flexibility, convenience and stability of its installation; at the same time, when the electromagnetic suction cup 6 is energized, the inner card slot 44 contacts the outer side of the metal magnetic block 8 after the two L-shaped card seats 4 are relatively displaced, so that the metal magnetic block 8 can synchronize with the iron sheet inside the magnetic inner card slot 44, thereby improving the stability of the L-shaped card seat 4 and preventing it from moving. When operating the buttons on the control panel on the upper side of the amplifier body 1, it is only necessary to open the transparent protective cover 2 connected by the rotating buckle, and the transparent protective cover 2 plays a role in dust and touch protection.

The optical fiber amplifier according to claim 1, characterized in that: The four corners of the protection frame (3) are respectively provided with Z-shaped connecting pieces (31), the bottom surface of the Z-shaped connecting piece (31) is flush with the bottom surface of the electromagnetic suction cup (6), and the Z-shaped connecting piece (31) is provided with a mounting hole. The bottom of the protection frame (3) is provided with a sliding slot (32), and the electromagnetic suction cup (6) is slidably embedded in one side of the sliding slot (32) and is fastened by screws.

9. The optical fiber amplifier according to claim 1, characterized in that: An iron block (12) is installed at the bottom of the amplifier body (1), and the iron block (12) is magnetically connected to the metal magnetic block (8). The upper side of the metal magnetic block (8) and the edge of the opposite side of the L-shaped card seat (4) are both compounded with a layer of rubber gasket.

10. A method for using an optical fiber amplifier according to any one of claims 1 to 9, characterized in that: When the electromagnetic suction cup (6) is not powered, the magnetism of the magnet (9) is used to act on the metal magnetic block (8) and the electromagnetic suction cup (6) respectively, so that the metal magnetic block (8) and the electromagnetic suction cup (6) synchronously generate a relatively stable weak magnetic field. At this time, the amplifier body (1) can be adsorbed and placed on the metal magnetic block (8) to be initially stabilized. Then, the relative displacement of the two L-shaped holders (4) is adjusted by the adjustment component (7), so that the elastic top plates (41) on the opposite sides of the two L-shaped holders (4) can be elastically pressed against the amplifier body (1) for elastic fixation and buffering. At this time, a strong magnetic field is formed by the power supply of the electromagnetic suction cup (6), thereby enhancing the magnetic connection effect of the magnet (9) and the metal magnetic block (8), improving the magnetic connection between the metal magnetic block (8) and the amplifier body (1), and the electromagnetic suction cup (6) after power supply can be used to quickly adsorb and fix it on an external designated metal workstation.
