Description

Technical Field

[0001] This utility model relates to the field of switchgear mechanical fault detection technology, and in particular to a switchgear mechanical fault detection device. Background Technology

[0002] As the core equipment for power distribution and control, the stable operation of the internal mechanical components of switchgear directly determines the safety and reliability of the entire power system. A switchgear mechanical fault detection device is a type of intelligent monitoring equipment specifically designed for medium and high voltage switchgear. Its core function is to integrate multiple types of sensors, data processing units, and linkage modules to collect the operating status parameters of key mechanical components of the switchgear in real time, and combine them with algorithms to analyze and identify mechanical anomalies. Ultimately, it can achieve fault warning, location, and data feedback, thereby avoiding safety accidents such as power outages and equipment burnout caused by mechanical faults and ensuring the reliable operation of the power system.

[0003] Traditional switchgear mechanical fault detection devices continuously collect mechanical fault signals by fixing detection sensors inside the cabinet. However, the sensor fixing structure has poor flexibility, often using rigid bolt connections or custom brackets. This makes it impossible to flexibly adjust the sensor detection direction according to the installation position, height, and angle of different mechanical components inside the switchgear, resulting in blind spots in some concealed areas and making it difficult to comprehensively capture fault signals. Utility Model Content

[0004] The purpose of this invention is to provide a switchgear mechanical fault detection device to solve the problem that existing switchgear mechanical fault detection devices are not easy to adjust.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a switch cabinet mechanical fault detection device, including a cabinet body;

[0006] A cabinet door is installed on one side of the cabinet. A magnetic base is installed inside the cabinet. An adjustment structure is fixed on one side of the magnetic base. The adjustment structure includes a hinge base fixed to one side of the magnetic base. A connecting block is installed inside the hinge base. A hinge shaft is fixed on both sides of the connecting block. Locking nuts are installed on the outer sides of the hinge shafts on both sides of the hinge base. A rotating groove is provided on one side of the connecting block. A rotating shaft is installed inside the rotating groove. A rotating block is fixed on the outer side of the rotating shaft. A movable groove is provided on the top side of the rotating groove inside the connecting block. A threaded rod is installed on the top side of the connecting block. A pressing block is movably connected to the bottom end of the threaded rod inside the movable groove.

[0007] One end of the rotating shaft is fixed to a fixing structure, and a detection sensor is installed inside the fixing structure.

[0008] Preferably, the cabinet body and cabinet door are made of stainless steel, and the magnetic base is made of high-magnetic neodymium iron boron material.

[0009] Preferably, the connecting block and the hinge seat are hinged together by a hinge shaft, the locking nut is threaded to the hinge shaft, the rotating shaft and the connecting block are rotatably connected by a rotating groove, and the rotating groove is in communication with the interior of the movable groove.

[0010] With the above structure, the locking nut and the hinge shaft are threaded together during use. After the vertical angle is adjusted to the correct position, the operator can tighten the locking nut clockwise so that the inner wall of the nut fits tightly against the outer side of the hinge seat. The vertical angle of the connecting block is firmly locked by the preload of the thread and the friction between the nut and the hinge seat.

[0011] Preferably, the threaded rod is threadedly connected to the connecting block, the outer side of the rotating block is provided with anti-slip texture, the bottom side of the pressing block is fixed with a rubber pad, and the bottom side of the pressing block abuts against the outer side of the rotating block.

[0012] With the above structure, the anti-slip texture on the outside of the rotating block increases its surface roughness and improves the static friction coefficient when in contact with the pressing block. The anti-slip texture can be effectively embedded in the rubber pad on the bottom side of the pressing block to counteract the sliding tendency caused by vibration, ensuring that the rotating block always remains in a fixed state, thereby maintaining the stability of the horizontal angle of the detection sensor.

[0013] Preferably, the fixing structure includes a support base fixed to one end of the rotating shaft. A placement plate is fixed to the bottom of the support base. A sliding groove is provided inside the placement plate. A bidirectional lead screw is installed inside the support base at the bottom of the placement plate. Movable plates are installed on both sides of the outside of the bidirectional lead screw. A sliding plate is fixed to the top of the movable plate inside the sliding groove. A clamping plate is fixed to the top of the sliding plate. A guide rod is fixed to one side of the clamping plate. Guide grooves are provided on both sides of the support base outside the guide rod. A spring is installed on the outside of the guide rod on one side of the clamping plate. A handle is fixed to one end of the bidirectional lead screw on one side of the support base.

[0014] Preferably, the movable plates are symmetrically distributed on the outside of the bidirectional lead screw, and the movable plates are threadedly connected to both sides of the outside of the bidirectional lead screw. The sliding plate and the placement plate are slidably connected by a sliding groove.

[0015] With the above structure, the skateboard and the placement board are slidably connected via a groove during use. The groove's shape provides a clear constraint on the skateboard's movement trajectory. When the moving board drives the skateboard, the skateboard can only move in a straight line along the length of the groove and cannot deviate to either side perpendicular to the clamping direction.

[0016] Preferably, a rubber pad is fixed on one side of the clamping plate, the guide rod and the support seat are slidably connected by a guide groove, and the clamping plate and the support seat are telescopically connected by a spring.

[0017] With the above structure, the cooperation between the guide rod and the guide groove can share the radial force generated during clamping. When the clamping plate applies clamping force to the sensor, part of the force will be transmitted to the support through the guide rod, avoiding the concentration of all force at the threaded connection between the bidirectional lead screw and the moving plate, reducing thread wear, preventing the lead screw from bending and deforming due to long-term uneven stress, extending the overall service life of the fixed structure, and reducing maintenance frequency and cost.

[0018] The advantages of the switchgear mechanical fault detection device provided by this utility model are as follows:

[0019] With an adjustable structure and a dual adjustment mechanism of hinge and rotation, the detection angle can be precisely controlled in multiple dimensions. In the vertical direction, the vertical angle between the detection sensor and the component to be detected inside the cabinet can be flexibly adjusted to meet the detection needs of mechanical components at different heights and installation angles within the switch cabinet. In the horizontal direction, the rotating shaft drives the rotating block to rotate, allowing for 360° adjustment of the sensor's horizontal orientation, ensuring accurate capture of fault signals from cabinet corners and concealed mechanical connections.

[0020] With a fixed structure, when the clamping plates on both sides are driven to move towards each other by a bidirectional screw, the spring between the clamping plate and the support will generate elastic buffer force. Together with the rubber pad on one side of the clamping plate, the sensor is stably clamped through the thread transmission of the bidirectional screw, preventing the sensor from slipping or shifting during the detection process. It also avoids the squeezing damage to the sensor caused by traditional rigid clamping, thus extending the service life of the sensor. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 The present invention provides a switch cabinet mechanical fault detection device, which includes a cabinet body 1.

[0029] Reference Figures 1-4 As shown, a cabinet door 2 is installed on one side of the cabinet body 1, and a magnetic base 3 is installed inside the cabinet body 1. The cabinet body 1 and the cabinet door 2 are made of stainless steel, and the magnetic base 3 is made of high-magnetic neodymium iron boron material. An adjustment structure 4 is fixed on one side of the magnetic base 3. The adjustment structure 4 includes a hinge seat 401 fixed to one side of the magnetic base 3. A connecting block 402 is installed inside the hinge seat 401. Hinges 403 are fixed on both sides of the connecting block 402. Locking nuts 404 are installed on the outer sides of the hinges 403 on both sides of the hinge seat 401. A rotating groove 405 is provided on one side of the connecting block 402. A rotating shaft 406 is installed inside the rotating groove 405. A rotating block 407 is fixed on the outer side of the rotating shaft 406. The connecting block 402 rotates inside the rotating groove 405. A movable groove 408 is provided on the top side of the groove 405. A threaded rod 409 is installed on the top side of the connecting block 402. A pressing block 410 is movably connected to the bottom end of the threaded rod 409 inside the movable groove 408. The connecting block 402 and the hinge seat 401 are hinged together by the hinge shaft 403. The locking nut 404 is threadedly connected to the hinge shaft 403. The rotating shaft 406 and the connecting block 402 are rotatably connected by the rotating groove 405. The rotating groove 405 is connected to the interior of the movable groove 408. The threaded rod 409 is threadedly connected to the connecting block 402. The outer side of the rotating block 407 is provided with anti-slip texture. A rubber pad is fixed on the bottom side of the pressing block 410. The bottom side of the pressing block 410 abuts against the outer side of the rotating block 407.

[0030] The angle between the connecting block 402 and the hinge seat 401 can be changed by rotating the connecting block 402. After adjusting to the target angle, tighten the locking nut 404 on the outside of the hinge shaft 403. The friction between the nut and the hinge seat 401 locks the hinge angle, preventing angle deviation during detection. Also, by rotating the support seat 501, the rotating shaft 406 is driven to rotate around its own axis, thereby adjusting the horizontal angle of the detection sensor 6 and aligning mechanical parts in different positions. When the horizontal angle is adjusted to the correct position, rotate the threaded rod 409. The threaded rod 409 moves downward along the movable groove 408 under the action of the thread, and the pressing block 410 at its bottom end descends accordingly. Since the bottom side of the pressing block 410 is fixed with a rubber pad, the friction with the outside of the rotating block 407 is increased. When the pressing block 410 and the rotating block 407 are in close contact, the rotation of the rotating shaft 406 is locked, ensuring the stability of the sensor position during detection and avoiding detection deviation due to vibration.

[0031] Reference Figures 2-5 As shown, a fixing structure 5 is fixed to one end of the rotating shaft 406. The fixing structure 5 includes a support base 501 fixed to one end of the rotating shaft 406. A placement plate 502 is fixed to the bottom end of the support base 501. A sliding groove 503 is provided inside the placement plate 502. A double-acting screw 504 is installed inside the support base 501 at the bottom end of the placement plate 502. Movable plates 505 are installed on both sides of the double-acting screw 504. A sliding plate 506 is fixed to the top of the movable plate 505 inside the sliding groove 503. A clamping plate 507 is fixed to the top of the sliding plate 506. A guide rod 508 is fixed to one side of the clamping plate 507. Guide grooves are provided on both sides of the support base 501 outside the guide rod 508. 509. A spring 510 is installed on the outside of the guide rod 508 on one side of the clamping plate 507. A handle 511 is fixed at one end of the double-acting screw 504 on one side of the support base 501. The moving plates 505 are symmetrically distributed on the outside of the double-acting screw 504. The moving plates 505 are threaded to both sides of the outside of the double-acting screw 504. The slide plate 506 and the placement plate 502 are slidably connected through the slide groove 503. A rubber pad is fixed on one side of the clamping plate 507. The guide rod 508 and the support base 501 are slidably connected through the guide groove 509. The clamping plate 507 and the support base 501 are telescopically connected through the spring 510. A detection sensor 6 is installed inside the fixed structure 5.

[0032] The detection sensor 6 is placed on the placement plate 502. When the handle 511 is turned to drive the bidirectional lead screw 504 to rotate, the two moving plates 505 on both sides move in opposite directions along the thread direction of the lead screw, thereby causing the slide plate 506 fixed at the top of the moving plate 505 to slide along the slide groove 503 on the placement plate 502. The clamping plate 507 fixed at the top of the slide plate 506 moves with the slide plate 506. When the clamping plates 507 on both sides approach the sensor, the guide rod 508 on one side of the clamping plate 507 slides along the guide grooves 509 on both sides of the support base 501 to ensure that the clamping plate 507 moves smoothly. At the same time, the clamping plate 507 and the support base 501 form a telescopic structure through the spring 510. The elastic force of the spring 510 can make the clamping plate 507 apply a uniform clamping force to the sensor, which can avoid damaging the sensor by clamping too tightly, and also prevent the sensor from shifting due to clamping too loosely. Finally, the detection sensor 6 is stably fixed and aligned with the area to be detected.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
