Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, and in particular to an optical fiber signal amplifier. Background Technology

[0002] A high-frequency fiber optic signal amplifier is a device used to amplify incoming signals in a fiber optic system. It can increase the signal strength of low-power optical signals by amplification. High-frequency fiber optic signal amplifiers are mainly used to amplify optical signals in fiber optic communication, thereby improving signal transmission quality and transmission distance.

[0003] A search revealed that prior art CN206181041 U discloses an optical fiber signal amplifier, including a housing. An exhaust grille is fixedly installed in the center of the front of the housing. An optical fiber interface is fixedly installed on the side of the exhaust grille. A slot for the housing is formed on the side of the optical fiber interface away from the exhaust grille. A locking block is movably fitted within the slot, with one end of the locking block located outside the slot. A screen is fixedly installed on the locking block. Side heat dissipation grooves corresponding to the screens are formed on the side of the housing, and an air vent is formed on the side of the top of the housing. This optical fiber signal amplifier improves the heat dissipation of the front of the signal transmitter by setting an exhaust grille, effectively ventilates and dissipates heat on both sides of the signal transmitter through the slot, and effectively dissipates heat on both sides of the top of the signal amplifier through the slot formed by the bottom block and the fixing block, while also preventing dust from entering, thus greatly improving the heat dissipation effect of the signal amplifier.

[0004] The above-mentioned equipment has the following problems when in use: In order to ensure the stable use of the amplifier, it needs to be fixedly installed in the corresponding position to perform the amplification function. However, when the amplifier is not in use, there is no effective protection device for the amplifier, which results in a limited lifespan of the amplifier and increased costs. Utility Model Content

[0005] The purpose of this invention is to provide an optical fiber signal amplifier that addresses the problem that existing optical fiber signal amplifiers lack effective protection when not in use, resulting in limited amplifier lifespan and increased costs.

[0006] To achieve the above objectives, this utility model provides an optical fiber signal amplifier, including a base plate, a protective cover, and an optical fiber signal amplifier body. The protective cover is detachably mounted on the base plate, and a control panel and indicator lights are installed on its front side. The optical fiber signal amplifier body is disposed inside the protective cover, and also includes a lifting mechanism.

[0007] The lifting mechanism includes a lifting plate, a T-shaped threaded sleeve, a mounting bracket, a screw, a reducer, an L-shaped plate, fixed ears, a T-shaped rod, a signal device, and a tilting device. The lifting plate is disposed on the upper side of the base plate and is detachably connected to the main body of the fiber optic signal amplifier. The T-shaped threaded sleeve is fixed on the lifting plate. The mounting bracket is fixedly connected to the base plate and located on the upper side of the lifting plate. The screw is rotatably connected to the base plate and the mounting bracket, and is threadedly engaged with the T-shaped threaded sleeve. The reducer is fixed to the top of the mounting bracket, and its output shaft is connected to the screw via a coupling and has a brake mechanism. The L-shaped plate is mounted on the base plate and close to the lifting plate. The fixed ears are fixedly connected to the protective cover and symmetrically arranged on both sides of the top outlet of the protective cover. The T-shaped rod is threadedly connected to the base plate and slidably connected to the lifting plate. The signal device is electrically connected to the control PLC on the mounting bracket and is disposed on the L-shaped plate. The control PLC is electrically connected to the control panel, the indicator light, and the reducer. The tilting device is disposed between the fixed ears.

[0008] The outer stepped cavity of the ventilation holes on both sides of the protective cover is equipped with a filter screen.

[0009] The signal device includes an upper photoelectric switch and a lower photoelectric switch. The upper photoelectric switch is electrically connected to the control PLC and is installed on the upper side of the L-shaped plate. The lower photoelectric switch is electrically connected to the control PLC and is installed on the lower side of the L-shaped plate.

[0010] The flipping device includes a rotating shaft and a rotating plate. The rotating shaft is rotatably connected to the fixed ears and is located between the fixed ears. The rotating plate is welded to the rotating shaft.

[0011] The lifting mechanism further includes a cooling fan and a protective net. The cooling fan is electrically connected to the control PLC and is located outside the heat dissipation cavity of the reducer opened on the protective cover. The protective net is fixed to the housing of the cooling fan.

[0012] This utility model discloses a fiber optic signal amplifier. When the fiber optic signal amplifier is not in use, the control panel first controls the reducer to rotate the screw. After the screw rotates, the lifting plate descends with the help of the T-shaped rod, thereby storing the fiber optic signal amplifier body inside the protective cover. Furthermore, the fixing lugs engage to flip the flipping device, sealing the cavity at the top of the protective cover from which the fiber optic signal amplifier body protrudes. This provides good protection for the fiber optic signal amplifier body when not in use, thus solving the problem that existing fiber optic signal amplifiers do not have an effective protection device when not in use, resulting in a limited lifespan and increased costs.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Example 1:

[0020] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the fiber optic signal amplifier. Figure 2This is a structural schematic diagram of the lifting plate 106. This utility model provides a fiber optic signal amplifier, including a base plate 101, a protective cover 102, a fiber optic signal amplifier body 103, a control panel 104, indicator lights 105, and a lifting mechanism. The lifting mechanism includes a lifting plate 106, a T-shaped threaded sleeve 107, a mounting bracket 108, a screw 109, a reducer 110, an L-shaped plate 111, a fixing ear 112, a T-shaped rod 113, a signal device, and a flipping device. The signal device includes an upper photoelectric switch 115 and a lower photoelectric switch 116. The flipping device includes a rotating shaft 117 and a rotating plate 118. This solution solves the problem that existing fiber optic signal amplifiers lack effective protection when not in use, leading to limited amplifier lifespan and increased costs. It is understood that the aforementioned solution provides good protection for the fiber optic signal amplifier body 103 when not in use.

[0021] In this embodiment, the protective cover 102 is detachably mounted on the base plate 101, and a control panel 104 and indicator lights 105 are installed on its front side. The fiber optic signal amplifier body 103 is disposed inside the protective cover 102. The protective cover 102 is fixed by bolts, and a through hole for cable entry and exit is provided on its left side. The control panel 104 is provided with corresponding control buttons. There are two indicator lights 105, the left one indicating the upward limit position detection switch signal of the lifting plate 106, and the right one indicating the downward limit position detection switch signal of the lifting plate 106.

[0022] The lifting plate 106 is disposed on the upper side of the base plate 101 and is detachably connected to the fiber optic signal amplifier body 103. The T-shaped threaded sleeve 107 is fixed on the lifting plate 106. The mounting bracket 108 is fixedly connected to the base plate 101 and located on the upper side of the lifting plate 106. The screw 109 is rotatably connected to the base plate 101 and the mounting bracket 108, and is threadedly engaged with the T-shaped threaded sleeve 107. The reducer 110 is fixed to the top of the mounting bracket 108, and its output shaft is connected to the screw 109 via a coupling and has a brake mechanism. The L-shaped... Plate 111 is mounted on the base plate 101 and close to the lifting plate 106. The fixing ears 112 are fixedly connected to the protective cover 102 and are symmetrically arranged on both sides of the top outlet of the protective cover 102. The T-shaped rod 113 is threadedly connected to the base plate 101 and slidably connected to the lifting plate 106. The signal device is electrically connected to the control PLC 114 on the mounting bracket 108 and is arranged on the L-shaped plate 111. The control PLC 114 is electrically connected to the control panel 104, the indicator light 105 and the reducer 110 respectively. The flipping device is arranged between the fixing ears 112. The T-shaped threaded sleeve 107 is fixed by bolts. The bottom of the screw 109 is mounted on a detachable bearing seat on the base plate 101 via a rotating bearing, and the top is mounted on the mounting bracket 108 via a rotating bearing. The mounting bracket 108 is fixed by bolts. The housing of the fiber optic signal amplifier body 103 is fixed by bolts arranged from bottom to top. The fiber optic signal amplifier body 103 can directly adopt existing technology, such as the device disclosed in CN222128455U. The reducer 110 is model 5GU-90K, which is fixed by bolts. The device is fixed and equipped with a brake mechanism for easy shaft locking when stopping. Its output shaft is connected to the screw 109 via a coupling. The L-shaped plate 111 is fixed with bolts. The external threaded end of the bottom of the T-shaped rod 113 is directly fitted with the threaded hole on the base plate 101. The lifting plate 106 is provided with a sliding hole that mates with the T-shaped rod 113. The signal device is used for limit position detection when the lifting plate 106 moves vertically. The flipping device is used for sealing the cavity protruding from the fiber optic signal amplifier body 103 located on the top of the protective cover 102.

[0023] Secondly, filters are installed in the stepped cavities on the outer sides of the ventilation holes on both sides of the protective cover 102. This structure helps to reduce the entry of external dust when the working components inside the protective cover 102 dissipate heat.

[0024] Then, the upper photoelectric switch 115 is electrically connected to the control PLC 114 and installed on the upper side of the L-shaped plate 111; the lower photoelectric switch 116 is electrically connected to the control PLC 114 and installed on the lower side of the L-shaped plate 111. Both the upper photoelectric switch 115 and the lower photoelectric switch 116 are model CDJ10-I 2A12AN, and are respectively installed on the L-shaped plate 111 using their own threaded tabs.

[0025] Finally, the rotating shaft 117 is rotatably connected to the fixed ear 112 and is located between the fixed ears 112; the rotating plate 118 is welded to the rotating shaft 117. The fixed ear 112 is directly provided with rotating holes that mate with the stepped portions on both sides of the rotating shaft 117. The fixed ear 112 is fixed to the protective cover 102 by bolts arranged from the inside to the outside. The rotating plate 118 is welded to the rotating shaft 117. The rotating plate 118 has symmetrical lifting grooves on both sides to facilitate its operation when flipped. At the same time, the lifting grooves are used to reduce weight. The rotating plate 118 can abut against the protective cover 102.

[0026] When using this invention to address the problem that existing fiber optic signal amplifiers lack effective protection when not in use, leading to limited amplifier lifespan and increased costs, the fiber optic signal amplifier body 103, when not in use, firstly, through the control panel 104, controls the reducer 110 to rotate the screw 109. After the screw 109 rotates, the lifting plate 106 descends with the cooperation of the T-shaped rod 113, thereby allowing the fiber optic signal amplifier body 103 to be housed within the protective cover 102. Furthermore, the flipping device is flipped by the cooperation of the fixing lug 112. The cavity at the top of the protective cover 102 through which the fiber optic signal amplifier body 103 protrudes is sealed, thereby providing good protection for the fiber optic signal amplifier body 103 when not in use. When the lower photoelectric switch 116 detects the signal of the lifting plate 106 during descent, the lifting plate 106 descends to its limit position, and the fiber optic signal amplifier body 103 is completely retracted. The indicator light 105 on the right side will then be powered on and raised. This solves the problem that existing fiber optic signal amplifiers do not have an effective protection device when not in use, resulting in a limited lifespan of the amplifier and increased costs.

[0027] Example 2:

[0028] like Figure 3 As shown, where Figure 3 This is a schematic diagram of the overall structure of the fiber optic signal amplifier. Based on the first embodiment, this utility model provides a fiber optic signal amplifier, and the lifting mechanism further includes a cooling fan 201 and a protective net 202.

[0029] The cooling fan 201 is electrically connected to the control PLC 114 and is located outside the heat dissipation cavity of the reducer 110 opened on the protective cover 102; the protective net 202 is fixed to the housing of the cooling fan 201. A ventilation cavity is provided on the protective cover 102 directly above the reducer 110. The housing of the cooling fan 201 is fixed with bolts and contains a micro motor and fan. The protective net 202 adopts a filter structure for ventilation and dust prevention.

[0030] In this embodiment, by providing the cooling fan 201 and the protective net 202, the cooling of the drive motor of the reducer 110 can be coordinated when the reducer 110 is working, which is beneficial to its stable operation.
