[0001] The invention relates to the technical field of electric variable measuring equipment, and in particular to an optical fiber current sensor acquisition device for a distribution network. Background Art

[0002] At present, small power supply equipment has integrated more and more new technologies. For example, switching power supply, hard switch, soft switch, voltage regulation, linear feedback voltage regulation, magnetic amplifier technology, digital control voltage regulation, PWM, SPWM, electromagnetic compatibility, etc. Actual demand directly promotes the continuous development and progress of power supply technology. In order to automatically detect and display current, and have automatic protection functions and more advanced intelligent control when dangerous situations such as overcurrent and overvoltage occur, power supply technology with sensor detection, sensor sampling, and sensor protection has gradually become a trend. Sensors for detecting current or voltage have emerged and are gradually favored by the majority of power supply designers.

[0003] For example, a data acquisition device suitable for a variety of current sensors disclosed in publication number CN111198298A belongs to the field of intelligent substation line detection technology. The data acquisition device includes a Rogowski coil sensor, a low-power coil sensor, a zero-flux current sensor and a data processing module. The data processing module includes a first signal processing unit, a second signal processing unit, a third signal processing unit and a data processing unit. The first signal processing unit, the second signal processing unit and the third signal processing unit are respectively connected to the data processing unit. The data processing unit processes the three received signals and then outputs them, so as to solve the problem of large detection error when detecting the line body in the existing data acquisition device.

[0004] When it is necessary to use an optical fiber current sensor for data collection, a collection device is generally used to perform the collection operation. The currently used collection devices, especially the collection devices using current sensors, will inevitably generate internal heat when collecting data from the current sensors. In addition, the collection devices generate severe heat and are relatively fragile during long-term operation. Excessive temperature, dust adhesion, and moisture will cause damage to the collection device, seriously affecting work efficiency.

The current sensor interface of the collection device is generally not connected to the current sensor line or when it is connected to the line, there will be some gaps.

DETAILED DESCRIPTION

[0074] The embodiment of the present invention provides an optical fiber current sensor acquisition device for a distribution network, which is used to solve the problem that the existing acquisition device is prone to heat up during long-term operation, and when dust enters the inside of the device, it will affect the heat dissipation efficiency of the device, thereby affecting the stability and reliability of the device.

[0075] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0076] See also Figure 1 and Figure 2 The present invention provides an optical fiber current sensor acquisition device for a distribution network, comprising an acquisition device 1, a heat dissipation pipe 4 being fixedly connected to the top inner wall of the acquisition device 1; the acquisition device 1 comprises an acquisition device body 11; acquisition device fixing plates 12 are fixedly connected to the left and right sides of the acquisition device body 11 respectively; the acquisition device fixing plate 12 is connected to a fixed base, and the acquisition device fixing plate 12 is used to fix the acquisition device 1 to the upper end surface of the fixed base; current sensor interfaces 13 are fixedly connected to the left and right sides of the front and rear sides of the acquisition device body 11 respectively.

[0077] In the embodiment of the present invention, when the collection device 1 is connected to the optical fiber current sensor, the line of the optical fiber current sensor can be connected to the collection device 1 through the current sensor interfaces 13 on the left and right sides of the front and rear sides of the collection device body 11. After the connection, the tops on the left and right sides of the front and rear sides of the collection device 1 can be rotated to cover the connection to prevent the connection from being loosened and affecting the collection. At the same time, the connection is covered to prevent dust from entering the interior of the collection device 1 through the current sensor interface 13 to cause damage to the interior of the collection device 1. When the collection device 1 runs for too long and the internal components or boards begin to emit heat due to long-term operation, the top of the heat dissipation pipe 4 is started to open the top front side of the heat dissipation pipe 4. When the inner wall of the heat dissipation pipe 4 is started, the heat inside the collection device 1 is extracted and transported out of the interior of the collection device 1 through the top front side of the heat dissipation pipe 4. When heat dissipation is not required, the heat dissipation port on the top front side of the heat dissipation pipe 4 is covered to prevent dust or water stains from entering the interior of the collection device 1 through the heat dissipation port to damage the collection device 1 and affect the work efficiency.

[0078] See also Figure 1 The present invention provides an optical fiber current sensor acquisition device for a distribution network, wherein the fixed base includes a mounting seat 2; the mounting seat 2 is movably connected to the bottom of the acquisition device 1; the left and right sides of the acquisition device 1 are movably connected to fixed plates 3; the opposite surfaces of the two fixed plates 3 are fixedly connected to mounting frames 5; the bottoms of the two mounting frames 5 are fixedly connected to the top of the mounting seat 2.

[0079] In the embodiment of the present invention, the collection device 1 is generally installed on a wall or a shelf, and is generally fixed by screws or screw shafts. When the collection device 1 needs to be removed for repair or maintenance, it is not easy to disassemble the collection device 1, and the originally prepared installation slot on the wall or shelf may not be aligned with the position of the connection port provided for the collection device 1. When installation is required, the staff needs to open a new installation slot, which is troublesome. When the collection device 1 needs to be installed and fixed, the mounting seat 2 is first placed at the position where it needs to be installed, and then the front sides of the mounting frames 5 on both sides of the top of the mounting seat 2 are rotated to adjust the position of the inside of the mounting frame 5 to align with the originally opened installation slot, and then the mounting frame 5 is adjusted to align with the originally opened installation slot. With the help of other tools to fix it, after fixing the mounting seat 2, pull the two fixing plates 3 on the opposite sides of the two mounting frames 5 toward one side of the mounting frames 5 to adapt to the width of the two sides of the collection device 1, and then place the collection device 1 on the top of the mounting seat 2, on the opposite sides of the two fixing plates 3, and then pull the tops of the two fixing plates 3 to make the insides of the two fixing plates 3 adapt to the thickness of the two sides of the collection device 1, and then release the two fixing plates 3 to reset and clamp the collection device 1 on its opposite sides. The insides of the two fixing plates 3 are reset to press down the upper sides of the collection device 1 to fix the collection device 1 on the top of the mounting seat 2. When disassembly is required, it is only necessary to manually pull the two fixing plates 3 to release the limit clamping of the collection device 1.

[0080] See also Figure 2 and Figure 3 The present invention provides an optical fiber current sensor acquisition device for a distribution network, wherein a current sensor interface 13 comprises a current sensor block 131; an outer wall of the current sensor block 131 is fixedly connected to an outer protective shell 132; one side of the current sensor block 131 penetrates to a side of the outer protective shell 132 away from a collection device body 11 and is provided with a plurality of interfaces 133; the upper and lower sides of the side of the outer protective shell 132 away from the collection device body 11 are respectively fixedly connected to horizontal plates 134; the left and right sides of the opposite surfaces of the two horizontal plates 134 are respectively fixedly connected to sliding rods 135.

[0081] See also Figure 2 and Figure 3 The inner wall of the upper horizontal plate 134 is slidably connected with a pressure plate 136; the bottom of the pressure plate 136 extends to the bottom of the upper horizontal plate 134 and is provided with a plurality of pressure grooves 139; the left and right sides of the pressure plate 136 are respectively fixedly connected with pressure plate sliders 1310; the inner walls of the two pressure plate sliders 1310 are slidably connected to the outer wall of the slide rod 135.

[0082] See also Figure 2 and Figure 3 A pressure plate transmission block 137 is fixedly connected to one side of the pressure plate 136 close to the outer protective shell 132 ; a screw rod 138 is threadedly connected to the inner wall of the pressure plate transmission block 137 , and the bottom of the screw rod 138 is movably connected to the top of the upper horizontal plate 134 .

[0083] See also Figure 2 and Figure 4 The heat dissipation pipe 4 includes a heat dissipation pipe body 41; the outer wall of the heat dissipation pipe body 41 is fixedly connected to the top inner wall of the collection device body 11; the bottom of the heat dissipation pipe body 41 penetrates to the inner wall of the collection device body 11 and is fixedly connected to a filter screen 44; the inner wall of the heat dissipation pipe body 41 is fixedly connected to an exhaust motor 42, and the output end of the exhaust motor 42 is fixedly connected to an exhaust fan 43; the top of the heat dissipation pipe body 41 penetrates to the outer wall of the collection device body 11 and is fixedly connected to an air outlet 45.

[0084] See also Figure 2 and Figure 4 A transmission groove 48 is provided at the top of the air outlet 45; a partition 49 is fixedly connected to the rear side of the transmission groove 48, and a motor 47 is fixedly connected to the rear side of the partition 49; the output end of the motor 47 passes through the front side of the partition 49 and is fixedly connected to a second screw rod 410; the front side of the second screw rod 410 is movably connected to the front side of the inner wall of the transmission groove 48; the outer wall of the second screw rod 410 is threadedly connected to a rotating rod transmission block 411, and the top of the rotating rod transmission block 411 is rotatably connected to a rotating rod 412; the side of the rotating rod 412 away from the rotating rod transmission block 411 is rotatably connected to a heat dissipation port baffle 413; the left and right sides of the heat dissipation port baffle 413 are respectively slidably connected to side limit blocks 46; the rear sides of the opposite surfaces of the two side limit blocks 46 are fixedly connected to the left and right sides of the air outlet 45.

[0085] In the embodiment of the present invention, in the process of connecting the acquisition device body 11 with the optical fiber current sensor, the line of the optical fiber current sensor needs to be connected through the current sensor interfaces 13 on the left and right sides of the front and rear sides of the acquisition device body 11. After the connection is completed, the pressure plate transmission block 137 is driven by rotating the screw rod 138 to drive the pressure plate 136 to move downward on the inner wall of the upper horizontal plate 134. The pressure groove 139 opened at the bottom of the pressure plate 136 presses the line to the bottom of the pressure plate 136. This not only prevents the loose connection from affecting the accuracy of the collection, but also covers the connection, effectively preventing dust from entering the interior of the acquisition device body 11 through the interface 133, thereby avoiding potential damage to the internal components of the acquisition device body 11 by dust.

[0086] When the collection device body 11 runs for a long time, the internal components or boards may begin to emit heat due to the long-term operation. In order to prevent the internal part of the collection device body 11 from overheating and affecting the working efficiency, the motor 47 is first started to drive the second screw rod 410 to rotate, and the second screw rod 410 drives the rotating rod transmission block 411 to move forward, pushing the rotating rod 412 to push up the heat dissipation port baffle 413, thereby opening the front side of the air outlet 45, and then, the exhaust motor 42 inside the heat pipe body 41 is started to drive the exhaust fan 43 to rotate, extract the hot air inside the collection device body 11, and dissipate it through the front side of the air outlet 45. When heat dissipation is not needed, the heat dissipation port baffle 413 will cover the front side of the air outlet 45 to prevent dust from entering the interior of the collection device body 11 through the front side of the air outlet 45, thereby avoiding potential damage to the collection device body 11 caused by dust.

[0087] In addition, in order to further optimize the heat dissipation effect, the outer wall of the heat dissipation tube body 41 can be designed in the form of heat dissipation fins. The heat dissipation fins can increase the heat dissipation surface area, thereby improving the heat dissipation efficiency. When the heat is conducted from the heat dissipation tube body 41 to the outer wall, the heat dissipation fins can dissipate the heat to the surrounding environment more quickly, and a heat dissipation coating is applied to the outer shell surface of the optical fiber current sensor interface 13. The heat dissipation coating can increase the thermal emissivity of the surface of the object and dissipate the heat in a radiation manner. The heat dissipation coating adopts an aluminum oxide heat dissipation coating, which has good electrical insulation properties and can effectively isolate the optical fiber current sensor interface 13 from other conductive components, prevent electrical interference and short circuits, and improve the measurement accuracy of the optical fiber current sensor.

[0088] It is worth mentioning that, by providing the collection device body 11, the air outlet 45, the pressure plate 136, and the heat dissipation port baffle 413, when the collection device body 11 is connected to the optical fiber current sensor, the pressure plate 136 moves downward and presses the line to the bottom of the pressure plate 136 through the pressure groove 139 opened at the bottom of the pressure plate 136, so as to prevent the connection from loosening and affecting the collection and cover the connection at the same time. When the collection device body 11 runs for too long, the internal components or electric boards begin to emit heat due to long-term operation. In order to prevent the internal overheating of the collection device body 11 from affecting the working efficiency, the starter motor 47 drives the heat dissipation port baffle 413 to push up and dissipate through the front side of the air outlet 45. When heat dissipation is not required, the heat dissipation port baffle 413 covers the front side of the air outlet 45 to prevent dust from entering the interior of the collection device body 11, thereby solving the problem that the collection device 1 generates severe heat and is relatively fragile during long-term operation. Excessive temperature, dust adhesion, moisture, etc. will cause damage to the collection device 1, seriously affecting work efficiency. In general, dust basically enters the interior of the collection device 1 through the current sensor interface 13. The current sensor interface 13 of the collection device 1 is generally not connected to the current sensor line or when it is connected to the line, there will be some gaps. Dust can easily enter the interior of the collection device 1 from the interface 133, causing damage.

[0090] See also Figure 1 and Figure 7 The fixed plate 3 includes a rotating shaft 31; one side of the rotating shaft 31 is fixedly connected to the outer wall of the side frame 51; the inner wall of the rotating shaft 31 is rotatably connected to two second rotating rods 32; the two second rotating rods 32 are rotatably connected to the sides away from the rotating shaft 31 with sliders 34; the opposite sides of the two second rotating rods 32 are fixedly connected to springs 33; the outer walls of the two sliders 34 are slidably connected to slide plates 35; the side of the slide plate 35 away from the rotating shaft 31 is fixedly connected to a limiting plate 36.

[0091] See also Figure 1 , Figure 7and Figure 8 The limit plate 36 includes a limit plate shell 361; the inner wall of the limit plate shell 361 is slidably connected to a fixed pressure plate 364; the bottom of the fixed pressure plate 364 is movably connected to the top of the collection device fixed plate 12; the top of the fixed pressure plate 364 is fixedly connected to a plurality of spring pull rods 362; the tops of the plurality of spring pull rods 362 penetrate to the outer wall of the limit plate shell 361 and are fixedly connected to a pull handle 363.

[0092] It is worth mentioning that the spring pull rod 362 and the limit plate housing 361 are both made of high-strength spring steel, which can withstand greater tension or pressure loads. They not only have good elasticity and durability, but also can provide a certain pre-tightening force when fixed, ensuring the firmness of the acquisition device body 11 on the mounting seat 2, and improving the firmness and stability of the connection.

[0093] It is worth mentioning that a micro magnetic field generator is provided on the limit plate housing 361, and an annular magnetic lubricating oil groove is provided at the position where each spring pull rod 362 passes through the limit plate housing 361. Under the action of the micro magnetic field generator, the lubricating oil forms a more uniform lubricating film under the action of the magnetic field, which can reduce the friction coefficient, make the spring pull rod 362 more smoothly retract and retract, and reduce energy loss; at the same time, the lubricating oil film can absorb and disperse the tiny protrusions on the metal surface, prevent direct collision of the metal surface, significantly reduce wear, thereby avoiding the occurrence of metal adhesion and biting, and solving the technical problem of avoiding component jamming.

[0094] It should be noted that the magnetic lubricating oil can also absorb metal debris or other impurities to prevent them from entering the lubricating oil tank, thereby keeping the space between the spring pull rod 362 and the limiting plate housing 361 clean.

[0095] The annular magnetic lubricating oil groove surrounds the outside of the spring pull rod 362 to ensure that the magnetic lubricating oil can be evenly distributed on the contact surface between the spring pull rod 362 and the limit plate housing 361. The width of the annular magnetic lubricating oil groove should be slightly larger than the diameter of the spring pull rod 362 to ensure that the magnetic lubricating oil can fully cover the surface of the spring pull rod 362. The depth of the annular magnetic lubricating oil groove can be designed to be 0.5mm to 1mm according to the lubrication requirements, which can accommodate enough lubricating oil without causing leakage due to excessive oil.

[0096] In the embodiment of the present invention, when it is necessary to install the collection device 1, first rotate the front end of the side frames 51 on both sides of the mounting seat 2 to drive the bidirectional screw rod 52 on the inner wall of the side frame 51 to rotate. After the bidirectional screw rod 52 rotates, the connecting block transmission block 53 drives the connecting block rotating block 54 to move to align with the mounting groove opened on the wall panel or the iron frame. If the mounting groove is set on the side wall, it can be directly installed through the fixing groove 57 opened by the connecting block 56 with the help of other tools. If the mounting groove is opened on the bottom plate, rotate the limit rotating plate 55 to one side. After the limit rotating plate 55 rotates, the limit on the connecting block 56 is released, and the connecting block 56 can be rotated to be parallel to the bottom plate and fixed by other tools.

[0097] After the mounting seat 2 is fixed by the side frames 51 on both sides, the limit plates 36 on the opposite sides of the two side frames 51 are pulled toward the side frames 51, and the limit plates 36 pull the pressing slider 34 to drive the two springs 33 to rotate and pull the slider 34 on the opposite side to adapt to the width of the collection device body 11, and at the same time, pull the handle 363 on the top of the limit plate 36 to drive the fixed pressure plate 364 inside the limit plate shell 361 to pull upward to adapt to the thickness of the collection device fixed plate 12, and then release the limit plate shell 361, the limit plate shell 361 is reset through the slider 34 to push and squeeze the two sides of the collection device body 11, and at the same time, release the handle 363, the spring pull rod 362 resets the fixed pressure plate 364 to press the collection device fixed plate 12 downward, and fix the collection device body 11 on the top of the mounting seat 2.

[0098] The design of the optical fiber current sensor acquisition device fully considers the convenience and stability of on-site installation. Its unique bidirectional screw rod 52 and connecting block transmission block 53 structure enable the device to be quickly aligned and installed in different installation slots, and can achieve accurate installation on both the side wall and the bottom plate. In addition, the design of the limit rotating plate 55 not only ensures the freedom of the connecting block 56 during the installation process, but also ensures the stability and reliability of the connecting block 56 after the installation is completed.

[0099] In practical applications, the installation process of the device does not require complicated tools, which greatly reduces the time and labor intensity required for on-site installation. The installation of the entire optical fiber current sensor collection device for the distribution network can be completed through simple rotation and pulling operations, which not only improves work efficiency, but also reduces the risk of equipment failure caused by improper installation. In addition, the combined design of the spring pull rod 362 and the fixed pressure plate 364 ensures the firmness of the collection device body 11 on the mounting base 2, and can maintain a stable working state even in harsh operating environments;

[0100] In summary, the optical fiber current sensor acquisition device for distribution network not only reflects innovation in structural design, but also demonstrates extremely high practical value in practical applications. Its simple and quick installation method and stable and reliable structural design provide an efficient and stable solution for current monitoring in distribution networks.

[0101] It is worth mentioning that, by providing the mounting seat 2, the limiting plate 36 and the side frame 51, when the collection device 1 needs to be installed, first rotate the front end of the side frames 51 on both sides of the mounting seat 2, and the connecting block transmission block 53 drives the connecting block rotating block 54 to move and align with the mounting grooves opened on the wall panel or the iron frame, and directly install it with the help of other tools, and the limiting plate 36 pulls and presses the sliding block 34 to drive the two springs 33 to rotate and pull the sliding block 34 on the opposite side to adapt to the width of the collection device body 11, and then the collection device body 11 is placed on the opposite sides of the two limiting plates 36 and then released to clamp it, and at the same time pull The movable limit plate 36 adapts to the thickness of the collection device fixing plate 12, and then the reset fixing pressure plate 364 is loosened to press the collection device fixing plate 12 downward, which solves the problem that the collection device 1 is generally installed on a wall or a shelf, and the collection device 1 is generally fixed by screws or screw shafts. When the collection device 1 needs to be removed for repair or maintenance, it is not easy to disassemble the collection device 1, and the installation groove originally prepared on the wall or the shelf may not be aligned with the connection port position of the collection device 1. When installation is required, the staff needs to open a new installation groove, which is troublesome.

[0102] Working principle of the present invention:

[0103] When the acquisition device body 11 is connected to the optical fiber current sensor, the line of the optical fiber current sensor can be connected to the acquisition device 1 through the current sensor interfaces 13 on the left and right sides of the front and rear sides of the acquisition device body 11. After the connection, the screw rod 138 is rotated to drive the pressure plate transmission block 137 to drive the pressure plate 136 to move downward on the inner wall of the upper horizontal plate 134, and the line is pressed to the bottom of the pressure plate 136 through the pressure groove 139 opened at the bottom of the pressure plate 136 to prevent the connection from loosening and affecting the acquisition. At the same time, the connection is covered to prevent dust from entering the interior of the acquisition device body 11 through the interface 133 to cause damage to the interior of the acquisition device body 11. When the acquisition device body 11 runs for too long, the internal components or circuit boards will be damaged due to long-term operation. When the heat starts to be emitted, in order to prevent the inside of the collection device body 11 from overheating and affecting the working efficiency, the motor 47 is first started to drive the second screw rod 410 to rotate, and the second screw rod 410 drives the rotating rod transmission block 411 to move forward to push the rotating rod 412 to push up the heat dissipation port baffle 413 to open the front side of the air outlet 45, and then the exhaust motor 42 inside the heat pipe body 41 is started to drive the exhaust fan 43 to rotate to extract the hot air inside the collection device body 11 and emit it through the front side of the air outlet 45. When heat dissipation is not needed, the heat dissipation port baffle 413 covers the front side of the air outlet 45 to prevent dust from entering the inside of the collection device body 11 through the front side of the air outlet 45 and causing damage to the collection device body 11;

[0104] When it is necessary to install the collection device 1, first rotate the front end of the side frames 51 on both sides of the mounting seat 2 to drive the bidirectional screw rod 52 on the inner wall of the side frame 51 to rotate. After the bidirectional screw rod 52 rotates, the connecting block transmission block 53 drives the connecting block rotating block 54 to move to align with the mounting groove opened on the wall panel or the iron frame. If the mounting groove is set on the side wall, it can be directly installed with the help of other tools through the fixing groove 57 opened by the connecting block 56. If the mounting groove is set on the bottom plate, rotate the limit rotating plate 55 to one side. After the limit rotating plate 55 is rotated, the limit on the connecting block 56 is released, and the connecting block 56 can be rotated to be parallel to the bottom plate and fixed by other tools. After the mounting seat 2 is fixed by the side frames 51 on both sides, pull the two The limit plate 36 on the opposite side of the side frame 51 is pulled toward the side frame 51, and the limit plate 36 pulls and presses the sliding block 34 to drive the two springs 33 to rotate and pull the sliding block 34 on the opposite side to adapt to the width of the collection device body 11. At the same time, the handle 363 on the top of the limit plate 36 is pulled to drive the fixed pressure plate 364 inside the limit plate shell 361 to pull upward to adapt to the thickness of the collection device fixed plate 12. Then, the limit plate shell 361 is released, and the limit plate shell 361 is reset through the sliding block 34 to push and squeeze the two sides of the collection device body 11. At the same time, the handle 363 is released, and the spring pull rod 362 resets the fixed pressure plate 364 to press the collection device fixed plate 12 downward to fix the collection device body 11 on the top of the mounting seat 2.
