Description

Technical Field

[0001] This utility model relates to the field of analysis device technology, specifically to an electrical fault analysis device. Background Technology

[0002] In the fault diagnosis system of electrical cabinets such as high and low voltage switchgear and distribution panels, electrical fault analysis devices need to be fixed in the cabinet with multiple bolts to prevent the detection probe from detaching from the tested component due to device displacement, and to ensure the stability of weak electrical signal acquisition. Electrical fault analysis devices are widely used to monitor and diagnose circuit abnormalities, short circuits, overloads and other problems. However, in actual application scenarios, due to the complex operating environment of the equipment, such as high temperature and dust, or due to the need for regular maintenance, fault diagnosis, upgrades and renovations, such devices often need to be frequently disassembled and reinstalled.

[0003] In existing technologies, electrical fault analysis devices mostly use multiple bolts for rigid connection. Although this can ensure high structural strength, it is inconvenient when frequent disassembly and assembly are required. Each maintenance requires the use of tools to loosen and tighten multiple bolts, which takes a long time. If the space inside the electrical cabinet is narrow, the staff may need to crouch or enter the limited work area in an awkward posture, which increases the labor intensity and is prone to misoperation due to obstructed vision. In harsh environments with high temperature, high humidity or dust, it poses a potential threat to the health of personnel. In addition, the lighting conditions in the small space are usually poor, which increases the difficulty of the work.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide an electrical fault analysis device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides an electrical fault analysis device, including a fixed frame and an analysis device body. A fixing component is installed inside the fixed frame. The fixing component includes a fixing plate installed on the inner wall of the fixed frame. Movable blocks are slidably connected to both sides of the top of the fixing plate. A guide post is fixedly connected to the side of each movable block near the top. Sliding blocks are slidably connected to both ends of the guide post. A movable plate is fixedly connected to the bottom of each sliding block. A sliding groove is fixedly connected to the bottom of the movable plate on the side away from the sliding block. A first guide rail is slidably connected to the inner wall of each sliding groove. A through groove is opened at the bottom of the movable block, and the movable block is slidably connected to a second guide rail through the through groove. A support plate is fixedly connected to the outer wall of the movable plate on the side near the sliding block. A driving component is connected to the side of each movable block away from the guide post.

[0007] Furthermore, the drive assembly includes two rotating rods rotatably connected to the inner wall of the fixed frame. A first bevel gear is fixedly connected to one end of each rotating rod. A second bevel gear is meshed with the adjacent side of the two first bevel gears. A linkage rod is fixedly connected to the adjacent side of the two second bevel gears. A third bevel gear is fixedly connected to the other end of each rotating rod. A fourth bevel gear is meshed with the outer wall of one side of the third bevel gear. A threaded rod is fixedly connected to the side of the fourth bevel gear away from the third bevel gear. The outer wall of the threaded rod is threadedly connected to the inner wall of the moving block.

[0008] Furthermore, the inner sides of the four support plates are in contact with the outer wall of the analyzer body near the bottom. The fixing assembly is in contact with the analyzer body through the four support plates. The support plates are made of wear-resistant material, and the outer wall of each support plate is covered with anti-slip texture.

[0009] Furthermore, each second guide rail is perpendicular to the central axis of the fixed plate, and the included angle between the two first guide rails at opposite ends is approximately 120 degrees.

[0010] Furthermore, the linkage rod is rotatably connected to the inner wall of the fixed frame, the rotating rod is rotatably connected to the inner wall of the fixed frame, and the threaded rod is rotatably connected to the inner wall of the fixed frame.

[0011] Furthermore, one of the rotating rods has an extension rod installed at the end away from the third bevel gear, and the end of the extension rod away from the first bevel gear extends out from the inner wall of the fixed frame. A hexagonal block is installed at the end of the extension rod away from the first bevel gear.

[0012] Furthermore, an instrument panel is installed on one side of the top of the analytical device body, and limit stops are installed at both ends of the guide column.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By using the drive component and the fixed component, only the hexagonal block needs to be rotated to drive the support plate to retract or open synchronously through the guide column and the moving plate. In the case of frequent disassembly and maintenance, it is not necessary to remove multiple bolts. The component is driven by rotating only a rotating rod, which shortens the disassembly and assembly time and improves maintenance efficiency.

[0015] 2. The extension rod extends the drive point from inside the fixed frame to outside the electrical cabinet. Operators do not need to crouch inside the narrow cabinet and can complete all operations from outside the cabinet. This avoids the increased labor intensity caused by awkward postures and solves the problem of misoperation caused by obstructed vision and poor lighting inside the cabinet. At the same time, it reduces the time that personnel spend in harsh environments such as high temperature, high humidity and dust, reducing potential threats to their health.

[0022] 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.

[0023] Please see Figures 1-5This utility model provides a technical solution: an electrical fault analysis device, including a fixed frame 1 and an analysis device body 2. A fixing assembly is installed inside the fixed frame 1. The fixing assembly includes a fixing plate 18 installed on the inner wall of the fixed frame 1. Movable blocks 3 are slidably connected to both sides of the top of the fixing plate 18. A guide post 4 is fixedly connected to the side of each movable block 3 near its top. Sliding blocks 5 are slidably connected to both ends of the guide post 4. The guide post 4 transmits the horizontal movement of the movable block 3 to the sliding block 5. The sliding of the sliding block 5 drives the movable plate 6 to move. The guide post 4 is made of rigid material, which can withstand lateral forces during clamping and prevent deformation. A movable plate 6 is fixedly connected to the bottom end of each sliding block 5. A slide groove 7 is fixedly connected to the bottom end of the movable plate 6 away from the sliding block 5. A first guide rail 8 is slidably connected to the inner wall of each slide groove 7. The movable plate 6... The sliding of the sliding block 5 is converted into an oblique movement along the first guide rail 8. The movement trajectory of the moving plate 6 is constrained by the cooperation of the sliding groove 7 and the first guide rail 8. The bottom end of the moving block 3 is provided with a through groove. The moving block 3 is slidably connected to the second guide rail 9 through the through groove. The fixed plate 18 is fixed to the inner wall of the fixed frame 1 to provide a stable installation reference for the second guide rail 9 and the moving block 3. The moving block 3 is slidably connected to the second guide rail 9 through the through groove to realize the horizontal directional movement and prevent the moving block 3 from deviating. The outer wall of the moving plate 6 near the sliding block 5 is fixedly connected with a support plate 17. Each moving block 3 is connected to a drive component on the side away from the guide post 4. The support plate 17 directly abuts against the outer wall of the analyzer body 2, converting the oblique movement of the moving plate 6 into a clamping force on the analyzer body 2, thereby realizing the fixed positioning of the analyzer body 2.

[0024] See Figure 3The drive assembly includes two rotating rods 10 rotatably connected to the inner wall of the fixed frame 1. Each rotating rod 10 has a first bevel gear 11 fixedly connected to one end. The rotating rod 10 is the main shaft; one end receives power from the linkage rod 13 via the first bevel gear 11, and the other end transmits torque to the fourth bevel gear 15 via the third bevel gear 14, achieving horizontal power transmission. Second bevel gears 12 are meshed on adjacent sides of the two first bevel gears 11, and the linkage rod 13 is fixedly connected to adjacent sides of the two second bevel gears 12. The other end of each rotating rod 10 is fixedly connected to the third bevel gear 14, and the fourth bevel gear 15 is meshed on one outer wall of the third bevel gear 14. A threaded rod 16 is fixedly connected to the side of the fourth bevel gear 15 away from the third bevel gear 14. The outer wall of the threaded rod 16 is threadedly connected to the inner wall of the moving block 3. When one of the rotating rods 10 is rotated, the rotating rod 10 rotates around the inner wall of the fixed frame 1. The rotating rod 10 transmits torque to the linkage rod 13 through the meshing of the first bevel gear 11 and the second bevel gear 12 fixed at one end, causing the linkage rod 13 to rotate around its own axis. The second bevel gear 12 at the other end of the linkage rod 13 meshes with the first bevel gear 11 of another rotating rod 10, thereby causing the other rotating rod 10 to rotate. When the two rotating rods 10 rotate, the third bevel gear 14 rotates synchronously with the rotating rods 10. The rotation of the third bevel gear 14 causes the fourth bevel gear 15 to rotate around its own axis, thereby causing the threaded rod 16 fixed to the fourth bevel gear 15 to rotate synchronously along its own axis. Because the threaded rod 16 is threadedly connected to the inner wall of the moving block 3, and the moving block 3 is slidably connected to the second guide rail 9 through the through groove, the rotational motion is converted into the two moving blocks 3 sliding horizontally towards or away from each other along the second guide rail 9. Finally, the fixed component drives the support plate 17 to complete the clamping or releasing of the analysis device body 2.

[0025] See Figure 1 , Figure 2 The inner sides of the four support plates 17 are in contact with the outer wall of the analyzer body 2 near the bottom. The fixing component is in contact with the analyzer body 2 through the four support plates 17. The four support plates 17 are symmetrically distributed and move synchronously, forming an encircling contact from the four directions of the bottom of the analyzer body 2, which improves the overturning resistance of the analyzer body 2, avoids the body from shaking or displacement due to excessive force at a single point, ensures the relative position stability of the detection probe and the measured component, and ensures the continuity of fault signal acquisition.

[0026] See Figure 1 , Figure 2The support plate 17 is made of wear-resistant material. The outer wall of each support plate 17 is covered with anti-slip texture. The wear-resistant material can reduce surface wear after long-term use, reduce the decrease in clamping accuracy caused by deformation and thinning of the support plate 17, extend the overall service life of the component, ensure the positioning accuracy of the analysis device body 2, and provide a stable physical reference for fault detection signal acquisition. At the same time, the grid anti-slip texture can increase the friction coefficient between the support plate 17 and the outer wall of the analysis device body 2, and prevent the analysis device body 2 from loosening and shifting due to external force.

[0027] See Figure 5 Each second guide rail 9 is perpendicular to the central axis of the fixed plate 18. The perpendicularity between the second guide rail 9 and the central axis of the fixed plate 18 can strictly constrain the movement direction of the moving block 3 and prevent the moving block 3 from deviating from its trajectory when sliding. The included angle between the two first guide rails 8 and one end is about 120 degrees, so that the corresponding moving plate 6 is brought together along an oblique trajectory that is wider on the outside and narrower on the inside. The spacing between the force points is uniform, avoiding local stress concentration, effectively protecting the outer shell of the main body from being deformed by pressure, and extending the service life of the equipment.

[0028] See Figure 1 One of the rotating rods 10 has an extension rod installed at the end away from the third bevel gear 14. The end of the extension rod away from the first bevel gear 11 extends out from the inner wall of the fixed frame 1. A hexagonal block is installed at the end of the extension rod away from the first bevel gear 11. The extension rod extends the hexagonal block from the inside of the fixed frame 1 to the outside, so that the operating point is freed from the narrow space inside the electrical cabinet. The operator does not need to bend over or reach into the cabinet to operate, avoiding the hand from hitting the live parts or cables inside the cabinet. At the same time, it solves the problem that the narrow space inside the frame makes it impossible for the tool to exert force, improving the convenience and safety of operation.

[0029] Working principle: The hexagonal block drives one of the rotating rods 10 to rotate around the inner wall of the fixed frame 1. The rotating rod 10 transmits torque to the linkage rod 13 through the meshing of the first bevel gear 11 and the second bevel gear 12. The linkage rod 13 then drives the other rotating rod 10 to rotate synchronously through the meshing of the second bevel gear 12 on the other side. When the two rotating rods 10 rotate, they drive the threaded rod 16 to rotate. The threaded rod 16 is connected to the moving block 3 by a thread, which converts the rotational motion into the moving block 3 sliding horizontally along the second guide rail 9 in opposite directions or in opposite directions. When the moving block 3 slides, it pushes the moving plate 6 to move obliquely along the first guide rail 8. The moving plate 6 synchronously drives the support plate 17 with anti-slip texture to close or open. The four symmetrically distributed support plates 17 abut against the outer wall of the bottom end of the analysis device body 2, realizing the stable clamping or release of the body, ensuring the positioning accuracy and signal acquisition continuity during fault detection.

[0030] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
