Description

Technical Field

[0001] The utility model relates to the technical field of power systems, in particular to an intelligent wireless fiber detection device. Background Art

[0002] In smart substations, optical cables replace control cables as the main transmission medium for important signals such as secondary system relay protection, computer monitoring, energy metering, and status monitoring. This has made significant contributions to optimizing the number and cost of cables, saving metal materials, and improving the anti-interference performance of signal transmission.

[0003] At present, in the on-site optical cable connection construction of smart substations, the fusion splicing method is usually used to complete the connection of optical cables. The process is complicated and has high requirements on the operating level of personnel, the temperature and cleanliness of the construction environment, etc. In the process of substation construction, the optical fiber core sequence often melts incorrectly when the optical cable is fused, resulting in low fusion quality and uneven fusion quality. In addition, due to the complex construction process and the large number of optical fiber melting points, the problem of optical fiber core number melting errors will also occur. The intelligent wireless optical fiber inspection instrument is used to distinguish between optical cable cores. The module wireless communication uses LORA (Long Range Radio) wireless communication. The wireless remote control controls the laser emission and optical switch switching to select the optical path, distinguish the optical cable path, and then determine the optical cable core, thereby eliminating the optical cable fault, reducing the investment of manpower and material resources, and enhancing the stability of the power grid.

[0004] For example, in the prior art, patent publication CN212363612U discloses an intelligent wireless optical fiber inspection device that distinguishes between cores. The module wireless communication uses LORA (Long Range Radio) wireless communication. A wireless remote control controls laser emission and optical switch switching to select the optical path, distinguish the optical cable path, and then determine the optical cable core, thereby eliminating optical cable faults, reducing manpower and material resources, and enhancing power grid stability.

[0005] The intelligent wireless fiber detector needs to be equipped with 12 FC interface access channels. The FC interface channels are directly opened on the intelligent wireless fiber detector. When the intelligent wireless fiber detector is not in use, dust is likely to fall on the FC interface, affecting the connection between the FC connector on the optical cable and the FC interface. Moreover, when the FC connector on the optical cable is connected to the FC interface, if water is accidentally spilled on the connection between the FC connector and the FC interface, a short circuit or a disconnection may easily occur, which affects the service life of the intelligent wireless fiber detector. Therefore, an intelligent wireless fiber detection device is designed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to solve the problems existing in the above background technology and to propose an intelligent wireless fiber detection device.

[0007] The technical problem to be solved by the present invention is to provide an intelligent wireless fiber inspection device, which solves the problem in the prior art that the FC interface of the intelligent wireless fiber inspection instrument is exposed and easily falls into dust, and when in use, when water is spilled on the connection between the FC connector and the FC interface, it is easy to cause a short circuit or a break, thereby affecting the service life of the intelligent wireless fiber inspection instrument.

[0008] The utility model provides an intelligent wireless fiber inspection device, comprising a wireless remote controller and an intelligent wireless fiber inspection instrument. The intelligent wireless fiber inspection instrument is provided with a remote intelligent trigger type fiber inspection power supply system module, a circuit chip, an LD laser, a wireless communication module, an equipment main control system module, an optical switch, an LED indicator light, and a mechanical optical switch;

[0009] The intelligent wireless fiber detector is provided with multiple FC interfaces at the lower back side. A blocking plate is provided on the back side of the intelligent wireless fiber detector through a hinge rotation. The blocking plate is attached to one side of the intelligent wireless fiber detector and has multiple circular embedded holes.

[0010] Preferably, when the blocking plate is in a vertical state, the FC interface corresponds to the circular embedding hole one by one, and the FC interface is embedded in the embedding hole.

[0011] Preferably, the intelligent wireless fiber detector is equipped with a limit assembly for positioning the blocking plate, and the limit assembly includes a rectangular groove, a slide groove, a guide rod, a guide bar, a toggle block and a socket spring. The rectangular groove is opened at the left end of the surface of the blocking plate facing the intelligent wireless fiber detector, and the slide groove is opened below the left side surface of the intelligent wireless fiber detector. The guide rod is fixedly arranged in the slide groove, and the guide bar is passed through the guide rod. A toggle block is fixedly arranged at the center of the outer surface of the guide bar, and a socket spring is fixedly arranged between the end of the guide bar and the end of the slide groove.

[0012] Preferably, the rectangular groove matches the guide bar.

[0013] Preferably, when the sleeve spring is in a naturally extended state, the outer end of the guide bar extends out of the slide groove, and the length of the guide bar extending is equal to the thickness of the blocking plate.

[0014] Preferably, the bottom level of the guide bar is equal to the level of the blocking plate when it is in a vertical state.

[0015] Preferably, when the blocking plate is in a horizontal state, the upper surface level of the guide bar is equal to the top water level of the rectangular groove.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

When the intelligent wireless fiber detector is not in use, the blocking plate is rotated to a vertical position, and the blocking plate covers the FC interface on the intelligent wireless fiber detector, and the embedded hole on the blocking plate is sleeved on the FC interface, thereby achieving the effect of protecting the FC interface, preventing dust from falling into the intelligent wireless fiber detector when not in use, and ensuring the electrical connection between the FC connector on the optical cable and the FC interface; when in use, the blocking plate is rotated to a horizontal position, and the blocking plate can block the upper part of the FC connector and the FC interface, preventing water from spilling onto the FC connector and the FC interface, causing a short circuit or open circuit, thereby ensuring the service life of the intelligent wireless fiber detector.

[0018] 2. The utility model provides a limit assembly. When the blocking plate is in a horizontal and vertical state to protect the FC interface, the elastic force of the socket spring causes the guide bar to extend out of the slide slot. At this time, the outer end bottom of the guide bar is attached to the upper surface of the blocking plate, thereby preventing the blocking plate 3 from rotating along the hinge, thereby achieving the effect of positioning the blocking plate in a vertical state. When the FC connector on the optical cable needs to be connected to the FC interface, the guide bar is pushed inward by the toggle block so that the guide bar is completely embedded in the slide slot. At this time, the guide bar releases the positioning of the blocking plate in the vertical state, and the blocking plate is rotated along the hinge so that the blocking plate is in a horizontal state. When the toggle block is released, the rebound force of the socket spring pops out the guide bar, so that the guide bar extends into the rectangular groove on the blocking plate, thereby achieving the effect of positioning the blocking plate in a horizontal state. The operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figures 1-6 As shown, the embodiment of the present invention provides an intelligent wireless fiber inspection device, including a wireless remote control 1 and an intelligent wireless fiber inspection instrument 2. The intelligent wireless fiber inspection instrument 2 is provided with a remote intelligent trigger type fiber inspection power supply system module, a circuit chip, an LD laser, a wireless communication module, a device main control system module, an optical switch, an LED indicator light, and a mechanical optical switch;

[0030] The remote intelligent trigger fiber alignment instrument power supply system module uses a 9V DC power supply. The MP2315GJ power conversion chip converts the 9V voltage into 5V and 2.5V constant-current DC power to power the circuit chip and LD laser respectively. The LD laser uses a 650nm red visible light source or standard light source to emit red visible light signals or invisible standard light signals, and switches working states according to control instructions. The wireless communication module uses the high-performance wireless communication spread spectrum RF chip SX1278, which adopts efficient cyclic interleaved error correction and detection coding, has high anti-interference and sensitivity, a maximum transmission power of 100mw, and a receiving sensitivity as low as -132dB. Under the same power consumption conditions, it can transmit farther than other wireless methods, achieving the combination of low power consumption and long distance, and extending the communication distance by 3-5 times compared with traditional wireless RF communication under the same power consumption.

[0031] The communication data processing module uses the 8L151G low-power single-chip microcomputer chip to convert complex communication data into serial port protocol data. The equipment main control system module uses the STC90C52 single-chip microcomputer chip to effectively realize the intelligent control of wireless communication, optical switch, LD laser, and LED indicator light. The 1-to-N optical switch uses a 1-to-N mechanical optical switch to realize the switching and selection of optical paths. The signal indication module uses a low-power LED indicator to indicate the working status of the equipment and the status of the optical path.

[0032] A plurality of FC interfaces 201 are provided on the lower back of the intelligent wireless fiber detector 2 . A blocking plate 3 is provided on the back of the intelligent wireless fiber detector 2 via a hinge. The blocking plate 3 is attached to one side of the intelligent wireless fiber detector 2 and has a plurality of circular embedding holes 301 .

[0033] In this embodiment, when the blocking plate 3 is in a vertical state, the FC interface 201 corresponds to the circular embedding hole 301 one by one, and the FC interface 201 is embedded in the embedding hole 301 .

[0034] By providing the blocking plate 3, when the intelligent wireless fiber detector 2 is not in use, the blocking plate 3 is rotated to a vertical position, the blocking plate 3 covers the FC interface 201 on the intelligent wireless fiber detector 2, and the embedded hole 301 on the blocking plate 3 is sleeved on the FC interface 201, thereby achieving the effect of protecting the FC interface 201, preventing dust from falling into the intelligent wireless fiber detector 2 when not in use, and ensuring the electrical connection between the FC connector on the optical cable and the FC interface 201; when in use, the blocking plate 3 is rotated to a horizontal position, the blocking plate 3 can block the FC connector and the top of the FC interface 201, preventing water from spilling onto the FC connector and the FC interface 201 and causing a short circuit or open circuit, thereby ensuring the service life of the intelligent wireless fiber detector 2.

[0035] In this embodiment, the intelligent wireless fiber detector 2 is equipped with a limit assembly for positioning the blocking plate 3. The limit assembly includes a rectangular groove 302, a slide 4, a guide rod 5, a guide bar 6, a toggle block 601 and a socket spring 7. The rectangular groove 302 is opened at the left end of the surface of the blocking plate 3 facing the intelligent wireless fiber detector 2. The slide 4 is opened below the left surface of the intelligent wireless fiber detector 2. The guide rod 5 is fixedly arranged in the slide 4. The guide bar 6 is penetrated by the guide rod 5. The toggle block 601 is fixedly arranged in the center of the outer surface of the guide bar 6. The socket spring 7 is fixedly arranged between the end of the guide bar 6 and the end of the slide 4.

[0036] In this embodiment, the rectangular groove 302 matches the guide bar 6 .

[0037] In this embodiment, when the sleeve spring 7 is in a naturally extended state, the outer end of the guide bar 6 extends out of the slide groove 4 , and the extended length of the guide bar 6 is equal to the thickness of the blocking plate 3 .

[0038] In this embodiment, the bottom horizontal height of the guide bar 6 is equal to the horizontal height of the blocking plate 3 when it is in a vertical state, so that the guide bar 6 can easily limit the vertical state of the blocking plate 3.

[0039] In this embodiment, when the blocking plate 3 is in a horizontal state, the upper surface level of the guide bar 6 is equal to the top water level of the rectangular groove 302 , so that the guide bar 6 can limit the horizontal state of the blocking plate 3 .

[0040] By setting a limit assembly, when the blocking plate 3 is in a horizontal and vertical state to protect the FC interface 201, the elastic force of the socket spring 7 causes the guide bar 6 to extend out of the slide groove 4. At this time, the outer end bottom of the guide bar 6 is attached to the upper surface of the blocking plate 3, thereby preventing the blocking plate 3 from rotating along the hinge, thereby achieving the effect of positioning the blocking plate 3 in the vertical state. When the FC connector on the optical cable needs to be connected to the FC interface 201, the guide bar 6 is pushed inward by the toggle block 601 so that the guide bar 6 is completely embedded in the slide groove 4. At this time, the guide bar 6 releases the positioning of the blocking plate 3 in the vertical state, and the blocking plate 3 is rotated along the hinge so that the blocking plate 3 is in a horizontal state. The toggle block 601 is released, and the rebound force of the socket spring 7 pops out the guide bar 6, so that the guide bar 6 extends into the rectangular groove 302 on the blocking plate 3, thereby achieving the effect of positioning the blocking plate 3 in the horizontal state. The operation is simple and convenient.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
