Abstract
Description
Technical Field
[0001] This utility model relates to the field of equipment maintenance, and in particular to a foreign object removal device for the maintenance of power equipment. Background Technology
[0002] With the vigorous development of modern industry, power equipment, as the core of energy transmission and conversion, is crucial for ensuring the normal operation of social production and life.
[0003] Currently, white pollution such as plastic bags can easily drift into substation equipment and affect its normal operation. A search revealed that Chinese Patent Publication No. CN221736021U discloses a foreign object removal device for power equipment maintenance, which includes a horizontal plate, a threaded cylinder fitted and fixed inside the horizontal plate, a screw threadedly engaged in the inner cavity of the threaded cylinder, a rotating shaft fixed to one end of the screw, a hook fixed to the rotating end of the rotating shaft, a crushing tooth one fixed to one side of the inner cavity of the hook, a hydraulic telescopic rod fitted and fixed to the other side of the hook, a movable plate fixed to the telescopic end of the hydraulic telescopic rod, and a crushing tooth two fixed to the surface of the movable plate. The aforementioned application document describes a hook that can conveniently remove foreign objects from gaps in electrical equipment. If the foreign object is stuck in the gap, turning the handle will cause the screw to rotate inside the threaded cylinder. The screw will then move the hook, allowing for a more forceful pull to remove the foreign object from the gap. Furthermore, the movement of the extension end of the hydraulic telescopic rod will move the moving plate to compress the surface of the foreign object. The two crushing teeth can then be used to crush the foreign object by pressing it against each other, thus crushing it before it can be removed.
[0004] While the aforementioned application documents can achieve the effect of removing foreign objects, in actual use, because the crushing teeth are fixed, they can easily push foreign objects to a more distant position when using the equipment, making removal difficult. Therefore, a foreign object removal device for power equipment maintenance is proposed to solve the above problems. Utility Model Content

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.
[0034] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a foreign object removal device for power equipment maintenance, including a mounting frame 1, which is L-shaped. A mounting shell 5 is fixedly connected to the rear end of the mounting frame 1. An electric telescopic rod 6 is fixedly connected to the inner wall of the mounting shell 5. The output shaft of the electric telescopic rod 6 passes through the inner wall of the mounting shell 5 and the inner wall of the mounting frame 1 and is fixedly connected to the rear end of the moving block 4. A clamping piece 7 is fixedly connected to the inner side of the mounting frame 1. The end of the clamping piece 7 away from the mounting frame 1 is set as a pointed tooth. A rotating plate 8 is rotatably connected to the outer wall of the moving block 4. A clamping piece 10 is fixedly connected to the outer wall of the rotating plate 8. The clamping piece 10 matches the clamping piece 7, that is, when the clamping piece 10 is close to the clamping piece 7, the tip of the clamping piece 10 is exactly aligned with the recess of the clamping piece 7.
[0035] Reference Figure 2 - Figure 4The rear end of the mounting bracket 1 is provided with an extension mechanism 2. The extension mechanism 2 includes a fixed shell 21, which is a hollow cylinder. The inner wall of the front end of the fixed shell 21 is provided with a threaded groove. A threaded rod 22 is threadedly connected to the inner wall of the fixed shell 21. The external thread of the threaded rod 22 matches the shape of the threaded groove inside the fixed shell 21. A limiting groove 23 is provided on the inner wall of the threaded rod 22. The limiting groove 23 is shaped like a cylinder and a cuboid. A sliding piece 24 is slidably connected to the inner wall of the limiting groove 23. The shape of the sliding piece 24 matches the shape of the limiting groove 23, and the length of the sliding piece 24 is shorter than the length of the limiting groove 23. A rotating rod 25 is fixedly connected to the rear end of 4. The rotating rod 25 is cylindrical in shape. The outer wall of the rotating rod 25 passes through and is rotatably connected to the inner wall of the fixed shell 21. A control plate 26 is fixedly connected to the rear end of the rotating rod 25. The outer surface of the control plate 26 is provided with anti-slip texture. The anti-slip texture ensures that the operator can rotate the control plate 26 more easily. The front end of the threaded rod 22 is fixedly connected to the rear end of the mounting frame 1. A sliding groove 3 is opened on the right surface of the mounting frame 1. A moving block 4 is slidably connected to the inner wall of the sliding groove 3. The moving block 4 is shaped like a cuboid and a semi-cylinder connected together. The semi-cylinder design ensures that external objects can rotate easily.
[0036] Reference Figure 5 - Figure 7 The interior of the movable block 4 and the interior of the rotating plate 8 are jointly provided with a rotating mechanism 9. The rotating mechanism 9 includes a fixed rod 91, which is cylindrical in shape and located at the center of the semi-cylindrical region of the movable block 4. The outer wall of the fixed rod 91 passes through and is fixedly connected to the inner wall of the movable block 4. The outer wall of the fixed rod 91 also passes through and is rotatably connected to the inner wall of the rotating plate 8. The inner wall of the rotating plate 8 and the outer wall of the fixed rod 91 are elastically connected by a torsion spring 92. One end of the torsion spring 92 is fixedly connected to the inner wall of the rotating plate 8, and the other end is fixedly connected to the outer wall of the fixed rod 91. When the torsion spring 92 is not under stress, the rotation... The sliding direction of plate 8 and moving block 4 is perpendicular. The inner wall of rotating plate 8 has a cylindrical groove. Torsion spring 92 is set in the area where the cylindrical groove is located. The inner wall of moving block 4 has a pressure chamber 93. The inner wall of pressure chamber 93 is piston-connected to pressure block 94. The rear end of pressure block 94 is elastically connected to the inner wall of pressure chamber 93 by spring 95. One end of spring 95 is fixedly connected to the rear end of pressure block 94, and the other end of spring 95 is fixedly connected to the inner wall of pressure chamber 93. The inner wall of pressure chamber 93 is piston-connected to insertion block 96. The inner wall of rotating plate 8 has insertion hole 97. The shape of insertion hole 97 matches the shape of insertion block 96.
[0037] Reference Figure 5 - Figure 7The rotating mechanism 9 also includes a sliding groove 98. A second insert 99 is slidably connected to the inner wall of the sliding groove 98. The angle between the line connecting the center of the first insert 96 and the center of the fixed rod 91 and the line connecting the center of the second insert 99 and the center of the fixed rod 91 is 90 degrees. One end of the second insert 99 near the middle of the moving block 4 is elastically connected to the inner wall of the sliding groove 98 by a second spring 910. One end of the second spring 910 is fixedly connected to the end of the second insert 99 near the middle of the moving block 4, and the other end of the second spring 910 is fixedly connected to the inner wall of the sliding groove 98. A lever 911 is fixedly connected to the outer wall of the second insert 99. The lever 911 does not extend beyond the inner area of the sliding groove 98.
[0038] Working principle: When in use, the operator first starts the electric telescopic rod 6, which pushes the moving block 4 to the front. Then, the operator presses the two levers 911 in the direction of mutual approach, so that the levers 911 drive the plug block 99 to move away from the socket 97.
[0039] During the process of insert block 2 99 leaving socket 97, the operator rotates the rotating plate 8 by 90 degrees, so that the rotating plate 8 is parallel to the fixed shell 21. Since the moving block 4 is at the foremost position at this time, the pressure block 94 is under compression. Therefore, the pressure block 94 enters more of the internal area of the pressure chamber 93. Before the rotating plate 8 rotates, insert block 1 96 can generate an outward force due to the high air pressure inside the pressure chamber 93. Therefore, when the rotating plate 8 rotates, so that socket 97 is outside it, insert block 1 96 can enter the interior of socket 97 under pressure, thus enabling the rotating plate 8 to reach a fixed state.
[0040] At this time, the staff adjusts the total length between the mounting bracket 1 and the control plate 26 according to the required extension length. When extension is required, the staff rotates the control plate 26 while manually fixing the fixing shell 21. This causes the control plate 26 to rotate the rotating rod 25, which in turn causes the rotating rod 25 to rotate the sliding plate 24. As the sliding plate 24 rotates, it contacts the inner wall of the limiting groove 23, causing the threaded rod 22 to rotate. This causes the threaded rod 22 to move towards the front end during rotation, thereby achieving the effect of adjusting the total length.
[0041] After adjusting the length, the staff will insert the equipment into the area where the foreign object needs to be removed. When the clamping plate 2 10 is at the rear end of the foreign object, the staff will activate the electric telescopic rod 6, so that its output shaft will drive the moving block 4 to move backward.
[0042] When the moving block 4 moves to a point where it no longer contacts the inner wall of the front end of the slide groove 3, the pressure block 94 moves forward under the elastic force of the spring 95, thereby causing the insertion block 96 to reset under the action of air pressure. Therefore, at this time, the insertion block 96 leaves the insertion hole 97, releasing the limiting position of the rotating plate 8 and the moving block 4.
[0043] At this time, the rotating plate 8 rotates under the drive of the torsion spring 92. When the second insertion block 99 and the insertion hole 97 are in the matching position, the second insertion block 99 enters the interior of the insertion hole 97 under the elastic force of the second spring 910, so that the rotating plate 8 can be kept perpendicular to the fixed shell 21.
[0044] As the moving block 4 continues to move forward, it drives the rotating plate 8 and clamping plate 10 to move forward, thereby clamping the foreign object between clamping plate 7 and clamping plate 10. At this time, the staff can take out the equipment to remove the foreign object.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
