Description

Technical Field

[0001] The utility model relates to the technical field of novel multi-channel high-speed fiber Bragg grating demodulation modules, in particular to a novel multi-channel high-speed fiber Bragg grating demodulation module. Background Art

[0002] The multi-channel high-speed fiber Bragg grating demodulation module is a type of fiber optic sensing. The sensing process based on fiber Bragg grating obtains sensing information by modulating the fiber Bragg wavelength with external physical parameters.

[0003] For example, a multi-channel high-speed fiber Bragg grating demodulation module with the authorization announcement number "CN210862726U" has a data processing module that is electrically connected to the photoelectric receiving module. The data processing module analyzes and processes the electrical signal output by the photoelectric receiving module to calculate the central wavelength value of the fiber Bragg grating sensor to be tested; a signal output module that is electrically connected to the data processing module is used to output the collected data. The advantages of the tunable narrow-band laser light source used are narrow line width and high power, which greatly improves the signal-to-noise ratio of the system. However, in the use of the multi-channel high-speed fiber Bragg grating demodulation module, multiple multi-channel high-speed fiber Bragg grating demodulation modules are sometimes required for use. In order to save space and facilitate operation, they will be overlapped. The multi-channel high-speed fiber Bragg grating demodulation module itself does not support the structure. When overlapping, it will avoid bonding, which affects the normal heat dissipation of multiple multi-channel high-speed fiber Bragg grating demodulation modules. The accumulated heat will affect the inside of the multi-channel high-speed fiber Bragg grating demodulation module, thereby affecting the normal use of the multi-channel high-speed fiber Bragg grating demodulation module and shortening its service life. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A novel multi-channel high-speed fiber Bragg grating demodulation module is designed, comprising a high-speed fiber Bragg grating demodulation module and a notch, wherein the notches are respectively processed on the left and right sides of the top of the high-speed fiber Bragg grating demodulation module, the four corners of the bottom of the high-speed fiber Bragg grating demodulation module are respectively fixed with a base plate, the inner wall of the base plate is connected to a supporting structure, and a plug is inserted on the left side of the front of the high-speed fiber Bragg grating demodulation module.

[0007] Preferably, the supporting structure includes a straight rod and a screw rod, the front and rear sides of the outer wall of the straight rod are respectively rotatably connected to the inner wall of the base plate, the outer side of the straight rod is fixedly connected to the inner side of the screw rod, the outer wall of the screw rod is threadedly connected with a circular ring, and the outer wall of the straight rod is fixedly connected to a straight plate.

[0008] Preferably, the outer wall of the straight plate matches the inner diameter of the slot.

[0009] Preferably, a bent rod is fixedly connected to the front side of the plug.

[0010] Preferably, a front interface of the high-speed fiber Bragg grating demodulation module is plugged with a plurality of round rods.

[0011] Preferably, the front sides of the plurality of round rods are all fixedly connected with a transverse plate.

[0012] The utility model provides a novel multi-channel high-speed fiber Bragg grating demodulation module, which has the following beneficial effects: a circular ring is rotated outward on the outer wall of a screw rod in a supporting structure to separate the circular ring from the outer wall of a bottom plate, and then a straight plate is rotated downward on the inner wall of the bottom plate in cooperation with a straight rod; when the straight plate is rotated to a vertical state, the circular ring is rotated inward on the outer wall of the screw rod to press the inner side of the circular ring against the outer wall of the bottom plate; at this time, the screw rod and the straight rod are positioned, so that the straight plate is fixed in position; then, the outer wall bottom of the straight plate is plugged into the inner wall of a slot at the top of a second high-speed fiber Bragg grating demodulation module to complete overlapping placement, thereby ensuring normal use of the multi-channel high-speed fiber Bragg grating demodulation module and guaranteeing its service life.

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] Embodiment 1:

[0020] See also Figure 1-4In the present embodiment, a novel multi-channel high-speed fiber Bragg grating demodulation module comprises a high-speed fiber Bragg grating demodulation module 1 and a slot 4. The slots 4 are respectively processed on the left and right sides of the top of the high-speed fiber Bragg grating demodulation module 1. How to operate and use the high-speed fiber Bragg grating demodulation module 1 is already a prior art. Without going into too much detail, the model is selected according to the use requirements. The four corners of the bottom of the high-speed fiber Bragg grating demodulation module 1 are respectively fixedly connected with a base plate 3, and the inner wall of the base plate 3 is connected with a supporting structure 2. A plug 5 is inserted on the left side of the front of the high-speed fiber Bragg grating demodulation module 1, and the plug 5 is a rubber block.

[0021] The support structure 2 includes a straight rod 201 and a screw rod 202. The front and rear sides of the outer wall of the straight rod 201 are respectively connected to the inner wall of the bottom plate 3 for rotation. The straight rod 201 is subjected to force to rotate through the bearing on the inner wall of the bottom plate 3. The outer side of the straight rod 201 is fixedly connected to the inner side of the screw rod 202. The outer wall of the screw rod 202 is threadedly connected with a ring 203. The ring 203 is subjected to force to rotate forward and backward through the outer wall of the screw rod 202. The outer wall of the straight rod 201 is fixedly connected with a straight plate 204. The outer wall of the straight plate 204 matches the inner diameter of the slot 4.

[0022] The circular ring 203 is rotated outward on the outer wall of the screw rod 202 in the supporting structure 2 so that the circular ring 203 is separated from the outer wall of the bottom plate 3, and then the straight plate 204 is rotated downward on the inner wall of the bottom plate 3 in cooperation with the straight rod 201. When the straight plate 204 is rotated to a vertical state, the circular ring 203 is rotated inward on the outer wall of the screw rod 202 so that the inner side of the circular ring 203 is pressed against the outer wall of the bottom plate 3. At this time, the screw rod 202 and the straight rod 201 are positioned, so that the straight plate 204 is fixed in position. Then, the bottom of the outer wall of the straight plate 204 is plugged into the inner wall of the slot 4 at the top of the second high-speed fiber Bragg grating demodulation module 1 to complete the overlapping placement, thereby ensuring the normal use of the multi-channel high-speed fiber Bragg grating demodulation module and guaranteeing its service life.

[0023] A bent rod 6 is fixedly connected to the front of the plug 5, and the bent rod 6 is convenient for pulling the plug 5 to move. A plurality of round rods 7 are plugged into the front interface of the high-speed fiber grating demodulation module 1. The round rods 7 are made of rubber. A cross plate 8 is fixedly connected to the front of the plurality of round rods 7, and the cross plate 8 is convenient for pulling the round rods 7 to move.

[0024] Working principle:

[0025] High-speed fiber Bragg grating demodulation modules are placed in an overlapping manner:

[0026] First, the circular ring 203 is rotated outward on the outer wall of the screw rod 202 to separate the circular ring 203 from the outer wall of the bottom plate 3, and then the straight plate 204 is rotated downward on the inner wall of the bottom plate 3 in cooperation with the straight rod 201. When the straight plate 204 is rotated to a vertical state, the circular ring 203 is rotated inward on the outer wall of the screw rod 202 to make the inner side of the circular ring 203 press against the outer wall of the bottom plate 3. At this time, the screw rod 202 and the straight rod 201 are positioned, so that the straight plate 204 is fixed in position. Then, the bottom of the outer wall of the straight plate 204 is plugged into the inner wall of the slot 4 at the top of the second high-speed fiber grating demodulation module 1 to complete the overlapping placement.

[0027] High-speed fiber Bragg grating demodulation module wire connection:

[0028] The handle bend rod 6 is pulled forward, and the plug block 5 is gradually separated from the interface on the front of the high-speed fiber Bragg grating demodulation module 1. Then, the horizontal plate 8 is held and pulled forward, and the multiple round rods 7 are gradually separated from the interface on the front of the high-speed fiber Bragg grating demodulation module 1. Then, the wires are plugged into the corresponding interfaces on the front of the high-speed fiber Bragg grating demodulation module 1. When the multiple wires are plugged into the high-speed fiber Bragg grating demodulation module 1, the multi-channel operation is completed.

[0029] Embodiment 2:

[0030] See also Figure 1-4 In this embodiment, a novel multi-channel high-speed fiber Bragg grating demodulation module further includes fins 9, and the outer walls of the plurality of fins 9 are fixedly connected to the top of the high-speed fiber Bragg grating demodulation module 1.

[0031] Working principle:

[0032] When the high-speed fiber Bragg grating demodulation module 1 is in use, the bottom of the fin 9 fits with the structure of the inner wall of the high-speed fiber Bragg grating demodulation module 1. When heat is generated, the fin 9 can conduct the heat through its own copper material to achieve heat dissipation of the high-speed fiber Bragg grating demodulation module 1.
