Description

Technical Field

[0001] This invention belongs to the technical field of power distribution room monitors, specifically a partial discharge monitoring device for cable terminals in power distribution rooms. Background Technology

[0002] A power distribution room is a place for receiving, distributing, controlling, and protecting electrical energy. By using a partial discharge monitor, it is possible to detect whether there is a fault in the insulation of the distribution box, so that it can be prevented in the early stages, rather than waiting until the equipment has problems and heats up before taking remedial action.

[0003] In existing technologies, ultrasonic local sensor monitors are often installed on the outer surface of the distribution cabinet by magnetic adsorption. During remote monitoring, they can only acquire and transmit discharge data from the corresponding set of distribution boxes. If staff need to acquire discharge information from multiple distribution boxes in the power distribution room, multiple monitors need to be purchased according to the number of distribution boxes, which will increase the procurement cost and the subsequent maintenance cost of the equipment. Moreover, if the distribution box heats up too quickly during the monitoring process, causing a fire before the staff arrives at the power distribution room, it will also damage the corresponding monitor, resulting in greater losses. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention to solve its technical problems is: a partial discharge monitoring device for cable terminals in a power distribution room, comprising a power distribution room and further comprising: sliding tracks spaced around the perimeter of the power distribution room;

[0005] A power mechanism is installed above the power distribution room and a scanning mechanism is installed below the power mechanism, wherein the scanning mechanism is engaged with a slide rail;

[0006] The scanning mechanism includes:

[0007] The mounting bracket is located below the power mechanism, the housing is rotatably connected inside the mounting bracket, the adjustment components are symmetrically arranged on the outside of the mounting bracket, and the stabilizing components are arranged on the side of the housing away from the mounting bracket.

[0008] Furthermore, the scanning mechanism also includes:

[0009] A dust cover, which is installed on the outside of the housing and is snapped into the top of the housing;

[0010] The monitor is placed inside the housing. During installation, the dust cover is removed, the monitor is placed inside the housing, and then the dust cover is put back on, causing the housing to move the detection device.

[0011] Furthermore, the power mechanism includes:

[0012] A base plate is installed above the power distribution room, and a support column is provided above the base plate;

[0013] The limiting plate is installed above the support column. Two limiting holes are opened on the upper part of the limiting plate. The number of limiting plates can be selected according to the specifications of the power distribution room, so that large power distribution rooms can continue to be used simply by adding limiting plates and replacing the conveyor belt.

[0014] The active roller is installed inside the limiting hole and is connected to an external power source. The position of the active roller is selected according to the specifications of the power distribution room. Then, the power source is connected to make the active roller drive the conveyor belt to move, thereby moving the monitor to various positions in the power distribution room for scanning and monitoring.

[0015] Furthermore, the power mechanism also includes:

[0016] The limiting roller is installed on the side of the base plate away from the drive roller. The limiting roller is fixed at one end of the power distribution room and cooperates with the drive roller at the end of power distribution rooms of different specifications, so that the conveyor belt can drive the scanning mechanism to multiple positions in the power distribution room for detection.

[0017] A conveyor belt, which is wound around the outside of the limiting roller and the drive roller;

[0018] A moving component, which is mounted outside the conveyor belt.

[0019] Further, the moving component includes:

[0020] A connector, which is mounted on the outside of the conveyor belt;

[0021] A movable rod is inserted inside the connecting seat, and the surface of the movable rod is slidably connected to the inner wall of the connecting seat;

[0022] The extrusion wheel is rotatably connected inside the connecting seat, and the outside of the extrusion wheel is in contact with the surface of the moving rod. The extrusion wheel is made of rubber to increase the friction on the moving rod.

[0023] Furthermore, the moving component also includes:

[0024] The extrusion plate is symmetrically arranged inside the moving rod. The two ends of the extrusion plate are slidably connected to the inner wall of the moving rod, so that the extrusion plate unfolds and approaches the moving rod when it is extruded. The extrusion plate extrudes the connecting seat to stabilize the moving rod on the connecting seat, and avoids the moving rod from swaying left and right when moving, which would cause it to jam up and down.

[0025] A spring is installed in the middle of the extrusion plate, and the other end of the spring is connected to the outside of the moving rod to generate a supporting force on the extrusion plate, so that the extrusion plate is locked between the connecting seat and the moving rod to form a support.

[0026] Furthermore, the adjustment component includes:

[0027] The rotating rod is rotatably connected to the outside of the mounting bracket. The rotating rod has a built-in drive. By rotating, it drives the limit rod to pull the vertical sensor for adjustment, so that the housing is kept vertically placed. This avoids the monitor tilting due to gaps caused by the movement of the housing up and down, which would cause deviation in scanning detection.

[0028] A limiting rod, one end of which is slidably connected to the inner side of the rotating rod;

[0029] A collar, which is fitted onto the surface of the limiting rod.

[0030] Furthermore, the adjustment component also includes:

[0031] A vertical sensor is rotatably connected to the inside of the mounting bracket, and the outside of the vertical sensor is in contact with the housing.

[0032] A movable block is mounted on the other end of the collar, and the surface of the movable block is slidably connected to the surface of the vertical sensor.

[0033] Furthermore, the stabilizing component includes:

[0034] The locking block is installed on the outside of the housing and engages with the inside of the slide. A certain gap is maintained between the locking block and the slide to allow the locking block to have more room to move up and down in the slide.

[0035] The fixing grooves are symmetrically arranged on the side of the block near the slide rail;

[0036] Telescopic rods are symmetrically arranged on the outside of the locking block.

[0037] Furthermore, the stabilizing component also includes:

[0038] A magnetic block is installed at one end of the telescopic rod;

[0039] The roller is rotatably connected inside the fixed groove. The surface of the roller contacts the surface of the power distribution room. The magnetic strip makes the roller contact the surface of the power distribution room but not completely stick to it, so that the roller can move along the power distribution room, increasing the stability of the equipment and reducing the load on the moving rod.

[0040] Magnetic strips are evenly distributed on the outside of the roller.

[0041] The beneficial effects of this invention are as follows:

[0042] 1. This invention, by setting up a scanning mechanism, allows a stabilizing component to be inserted into the slide rail and adsorbed onto the surface of the power distribution room, moving along the surface of the power distribution room. This enables the monitor inside the housing to scan and monitor the power distribution room from top to bottom, and provides stronger support and stability for the monitor during slow movement, allowing the monitor to move slowly and steadily downwards. An adjustment component adjusts the monitor during the movement, and automatically calibrates when the monitor deviates, ensuring that the monitor remains vertical throughout the movement and avoiding the impact of equipment tilt on the monitoring results.

[0043] 2. This invention, by setting up a moving component, rotates the extrusion wheel to move the moving rod downwards, causing the extrusion plate to be compressed and retracted inside the moving rod. Under the drive of the spring, the extrusion plate generates a relative supporting force with the inside of the connecting seat, so that the moving rod is subjected to multiple forces to achieve vertical placement and balance. This reduces the shaking and jamming caused by fewer support points during movement, ensuring the flexibility of the moving rod while enhancing its stability, and enabling multiple and repeated monitoring scans around the power distribution room.

[0044] 3. This invention incorporates a stabilizing component. Magnetic strips spaced apart on the rollers attract the power distribution room, making the rollers move more smoothly on the room's surface while simultaneously providing attraction, thus increasing the stability and support of the clamping block. This ensures the monitor remains stable and reduces shaking during movement. After reaching the measurement position, a telescopic rod extends, contacting and adsorbing the magnetic block onto the power distribution room's surface. This allows the magnetic block to fix the clamping block to the outside of the power distribution room, enabling the monitor to hang stably on the surface for long-term monitoring data collection. The monitor can be flexibly used at multiple locations within the power distribution room, increasing the utilization rate of individual monitors, reducing the number of monitors deployed, and thus minimizing unnecessary expenses.

[0045] 4. By setting an adjustment component, the vertical sensor can be bound to the monitor inside the housing, controlling the angle of the monitor and preventing it from shifting due to shaking during movement, which would cause it to get stuck in the slide and affect the scanning. At the same time, it also ensures that the monitor always maintains a consistent relative distance from the power distribution room, avoiding the monitoring distance from fluctuating during the scanning process and affecting the judgment of the state inside the power distribution room.

Detailed Implementation

[0056] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0057] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: a partial discharge monitoring device for cable terminals in a power distribution room, which is described below.

[0058] Including power distribution room 1, and also including: sliding tracks 2 spaced around the power distribution room 1;

[0059] The power mechanism 3 is installed above the power distribution room 1 and the scanning mechanism 4 is installed below the power mechanism 3. The scanning mechanism 4 is engaged with the slide rail 2.

[0060] During installation, the power mechanism 3 is installed on the top of the power distribution room 1 according to its needs. The power mechanism 3 drives the scanning mechanism 4 to move to the slide rails 2 on each surface of the power distribution room 1. The scanning mechanism 4 enters the slide rails 2 and scans the power distribution room 1 from top to bottom. The partial discharge monitor 406 inside the scanning mechanism 4 performs a full scan of the power distribution room 1. When multiple power distribution rooms 1 need to be monitored, the power mechanism 3 can be laid on top of all power distribution rooms 1 to drive the scanning mechanism 4 to the position that needs to be monitored, thus reducing the number of partial discharge monitors 406.

[0061] Scanning mechanism 4 includes:

[0062] The mounting bracket 401 is located below the power mechanism 3, the housing 403 is rotatably connected inside the mounting bracket 401, the adjustment component 402 is symmetrically arranged on the outside of the mounting bracket 401, and the stabilizing component 404 is arranged on the side of the housing 403 away from the mounting bracket 401.

[0063] Scanning mechanism 4 also includes:

[0064] Dust cover 405 is installed on the outside of housing 403 and is snapped into the top of housing 403;

[0065] Monitor 406 is placed inside housing 403. During installation, remove dust cover 405, place monitor 406 inside housing 403, and then put dust cover 405 back on, so that housing 403 moves the detection equipment.

[0066] After the scanning mechanism 4 is driven by the power mechanism 3 to be inserted into the slide rail 2, the stabilizing component 404 is inserted into the slide rail 2 and adsorbed onto the surface of the power distribution room 1. It moves along the surface of the power distribution room 1, so that the monitor 406 inside the housing 403 scans and monitors the power distribution room 1 from top to bottom. It also provides stronger support and stability for the monitor 406 during slow movement, so that the monitor 406 can move down slowly and steadily. The adjusting component 402 adjusts the monitor 406 during the movement. When the monitor 406 deviates, it automatically calibrates, so that the monitor 406 always remains vertical during the movement, avoiding the monitoring results being affected by the tilt of the equipment.

[0067] The power mechanism 3 includes:

[0068] The base plate 301 is installed above the power distribution room 1, and a support column 302 is provided above the base plate 301.

[0069] Limiting plate 303 is installed above support column 302. Two limiting holes 304 are opened on the upper part of limiting plate 303. The number of limiting plates 303 can be selected according to the specifications of power distribution room 1, so that large power distribution room 1 can continue to be used simply by adding limiting plates 303 and replacing conveyor belt 308.

[0070] The active roller 305 is installed inside the limiting hole 304. The active roller 305 is connected to an external power source. The position of the active roller 305 is selected according to the specifications of the power distribution room 1. Then, the power source is connected to make the active roller 305 drive the conveyor belt 308 to move, thereby moving the monitor 406 to various positions in the power distribution room 1 for scanning and monitoring.

[0071] The power mechanism 3 also includes:

[0072] The limiting roller 306 is installed on the side of the base plate 301 away from the active roller 305. The limiting roller 306 is fixed at one end of the power distribution room 1 and cooperates with the active roller 305 at the ends of power distribution rooms 1 of different specifications, so that the conveyor belt 308 can drive the scanning mechanism 4 to multiple positions in the power distribution room 1 for detection.

[0073] The conveyor belt 308 is wound around the outside of the limiting roller 306 and the drive roller 305;

[0074] The moving component 307 is mounted outside the conveyor belt 308.

[0075] During installation, the number of limiting plates 303 is determined by the length of the power distribution room 1. Then, the limiting plates 303 are installed on the support column 302, so that the limiting plates 303 fix the drive roller 305 to the other two corners of the power distribution room 1. Then, the conveyor belt 308 is wrapped around the drive roller 305 and the limiting roller 306, and all the limiting plates 303 are covered, so that the conveyor belt 308 can move between the limiting plates 303 and the base plate 301. This allows for quick and easy installation of power distribution rooms 1 of different specifications.

[0076] In use, the transmission roller drives the moving component 307 to move around the power distribution room 1 and stops after reaching the designated position. Then the moving component 307 drives the scanning mechanism 4 downward, so that the scanning mechanism 4 can scan and monitor from top to bottom. This avoids the situation where the monitor 406 placed in a fixed position cannot completely cover the monitoring points required by the power distribution room 1, which would require the installation of more monitors 406 and increase the monitoring cost.

[0077] Example 2, please refer to Figures 1-9 The present invention provides a technical solution: based on embodiment 1, the moving component 307 includes:

[0078] Connector 3071 is installed on the outside of conveyor belt 308;

[0079] The movable rod 3073 is inserted inside the connecting seat 3071, and the surface of the movable rod 3073 is slidably connected to the inner wall of the connecting seat 3071.

[0080] The extrusion roller 3072 is rotatably connected inside the connecting seat 3071. The outer surface of the extrusion roller 3072 is in contact with the surface of the moving rod 3073. The extrusion roller 3072 is made of rubber to increase the friction on the moving rod 3073.

[0081] The mobile component 307 also includes:

[0082] The extrusion plate 3074 is symmetrically arranged inside the moving rod 3073. The two ends of the extrusion plate 3074 are slidably connected to the inner wall of the moving rod 3073, so that the extrusion plate 3074 unfolds and approaches the moving rod 3073 when it is extruded. The extrusion plate 3074 extrudes the connecting seat 3071 to stabilize the moving rod 3073 on the connecting seat 3071, and avoids the moving rod 3073 from swaying left and right when moving, which would cause it to jam when moving up and down.

[0083] Spring 3075 is installed in the middle of extrusion plate 3074. The other end of spring 3075 is connected to the outside of moving rod 3073, which generates a supporting force on extrusion plate 3074, so that extrusion plate 3074 is locked between connecting seat 3071 and moving rod 3073 to form support.

[0084] After moving to the designated position, the compression wheel 3072 rotates, moving the moving rod 3073 downwards. This causes the compression plate 3074 to be compressed and retracted inside the moving rod 3073. Under the drive of the spring 3075, the compression plate 3074 generates a relative supporting force with the interior of the connecting seat 3071, allowing the moving rod 3073 to be placed vertically and balanced by multiple forces. This reduces the shaking and jamming caused by fewer support points during movement, ensuring the flexibility of the moving rod 3073 while enhancing its stability, and enabling multiple and repeated monitoring scans around the power distribution room 1.

[0085] Adjustment component 402 includes:

[0086] Rotating rod 4021 is rotatably connected to the outside of mounting bracket 401. Rotating rod 4021 has a built-in drive. By rotating, it drives limit rod 4022 to pull vertical sensor 4025 for adjustment, so that housing 403 is kept vertically placed. This prevents the monitor 406 from tilting due to gaps caused by the movement of housing 403 when it is moved up and down, thus avoiding deviation in scanning detection.

[0087] Limiting rod 4022, one end of which is slidably connected to the inner side of rotating rod 4021;

[0088] The collar 4023 is fitted onto the surface of the limit rod 4022.

[0089] Adjustment component 402 also includes:

[0090] Vertical sensor 4025 is rotatably connected to the inner side of mounting bracket 401. The outer side of vertical sensor 4025 is in contact with housing 403. The upper part of vertical sensor 4025 is movably connected to the inside of mounting bracket 401, and can slide along mounting bracket 401 and rotate freely.

[0091] Movable block 4024 is installed at the other end of collar 4023, and the surface of movable block 4024 is slidably connected to the surface of vertical sensor 4025.

[0092] During use, if the housing 403 tilts, it will cause the vertical sensor 4025 to rotate, causing the moving block 4024 and the collar 4023 to deviate from the limiting rod 4022, thereby triggering the rotating rod 4021 to rotate, which will drive the limiting rod 4022 to return the vertical sensor 4025 to its original position. The vertical sensor 4025 can be bound to the monitor 406 inside the housing 403 to control the angle of the monitor 406, preventing the monitor 406 from deviating due to shaking during movement and causing jamming in the slide 2, thus affecting the scanning. At the same time, it also ensures that the monitor 406 always maintains a consistent relative distance from the power distribution room 1, preventing the monitor 406 from fluctuating in distance during the scanning process and affecting the judgment of the status inside the power distribution room 1.

[0093] Stable component 404 includes:

[0094] The locking block 4041 is installed on the outside of the housing 403. The outside of the locking block 4041 is engaged with the inside of the slide 2. A certain gap is maintained between the locking block 4041 and the slide 2, so that the locking block 4041 has more room to move up and down in the slide 2, making it easier to move up and down more smoothly.

[0095] The fixing groove 4042 is symmetrically arranged on the side of the locking block 4041 near the slide 2;

[0096] Telescopic rod 4043 is symmetrically arranged on the outside of the locking block 4041.

[0097] The stabilizing component 404 also includes:

[0098] Magnetic block 4044 is installed at one end of telescopic rod 4043;

[0099] Roller 4045 is rotatably connected inside the fixed groove 4042. The surface of roller 4045 is in contact with the surface of the power distribution room 1. The magnetic strip 4046 is set so that roller 4045 is in contact with the surface of the power distribution room 1 but not completely attracted, so that roller 4045 can move in close contact with the power distribution room 1, increasing the stability of the equipment and reducing the load on the moving rod 3073.

[0100] Magnetic strip 4046 is evenly distributed on the outside of roller 4045.

[0101] The monitor 406 has two scanning states. The first state is that it moves slowly up and down along the slide 2 under the drive of the moving component 307. At this time, the roller 4045 is attracted to the power distribution room 1, and the magnetic strips 4046 set at intervals on the roller 4045 are attracted to the power distribution room 1, making the movement of the roller 4045 on the surface of the power distribution room 1 smoother. At the same time, it also has a certain attraction, thereby increasing the stability and support of the card block 4041, so that the monitor 406 remains stable and reduces shaking during the movement.

[0102] After moving to the measurement position, the telescopic rod 4043 extends, bringing the magnetic block 4044 into contact with and adsorbing it onto the surface of the power distribution room 1. This allows the magnetic block 4044 to fix the clip 4041 to the outside of the power distribution room 1, enabling the monitor 406 to be stably hung on the surface of the power distribution room 1 for long-term monitoring data collection. This allows the monitor 406 to flexibly monitor multiple locations in the power distribution room 1, improving the utilization rate of a single monitor 406, reducing the number of monitors 406 deployed, and thus reducing unnecessary expenses.

[0103] The specific workflow is as follows:

[0104] During installation, the number of limit plates 303 is determined by the length of the power distribution room 1. Then, the limit plates 303 are installed on the support column 302, so that the limit plates 303 fix the drive roller 305 to the other two corners of the power distribution room 1. Then, the conveyor belt 308 is wrapped around the drive roller 305 and the limit roller 306, and all the limit plates 303 are covered, so that the conveyor belt 308 moves between the limit plates 303 and the base plate 301.

[0105] In use, the transmission roller drives the moving component 307 to move around the power distribution room 1 and stops after reaching the designated position. Then the moving component 307 drives the scanning mechanism 4 downward, so that the scanning mechanism 4 scans and monitors from top to bottom. This avoids the situation where the monitor 406 placed in a fixed position cannot completely cover the monitoring points required by the power distribution room 1, which would require the installation of more monitors 406 and increase monitoring costs.

[0106] After the scanning mechanism 4 is driven by the power mechanism 3 to be inserted into the slide rail 2, the stabilizing component 404 is inserted into the slide rail 2 and adsorbed onto the surface of the power distribution room 1. It moves along the surface of the power distribution room 1, so that the monitor 406 inside the housing 403 scans and monitors the power distribution room 1 from top to bottom. It also provides stronger support and stability for the monitor 406 during slow movement, so that the monitor 406 can move down slowly and steadily. The adjusting component 402 adjusts the monitor 406 during the movement. When the monitor 406 deviates, it automatically calibrates, so that the monitor 406 always remains vertical during the movement, avoiding the monitoring results being affected by the tilt of the equipment.

[0107] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
