Description

Technical Field

[0001] This utility model relates to the technical field of power maintenance devices, and in particular to a power equipment fault location device. Background Technology

[0002] As a vital infrastructure of modern society, the stable operation of the power system directly impacts industrial production, commercial activities, and residents' lives. However, due to the long-term influence of complex environmental factors such as wind, rain, lightning, and mechanical stress, power equipment and lines are prone to aging, breakage, and other faults, leading to power outages. Therefore, reconnecting broken power lines is a common task in power maintenance.

[0003] To ensure the stability and convenience of the connection process, Chinese Patent Publication No. CN113075587A discloses a fault location device for power equipment and its usage method, including a mounting plate. A fixing block is welded to the top of the mounting plate. A sliding groove is formed on the top of the mounting plate and is located on one side of the fixing block. A sliding plate is slidably placed inside the sliding groove. A connecting block is fixed to the top of the sliding plate by bolts. A slider is welded to the top of the connecting block. Both the slider and the top of the fixing block are welded with an annular fixing member. A groove is formed on the top of the annular fixing member.

[0004] However, this solution has certain limitations in practical applications: because the two cable segments are fixed by independent top and bottom fixing teeth, the positions of the two cable segments cannot be precisely aligned, which makes the cable splicing process inconvenient and may even require repeated unlocking and adjustment due to misalignment, seriously affecting maintenance efficiency. Utility Model Content

[0005] This invention provides a power equipment fault location device that can accurately locate cables and achieve precise connection, aiming to improve maintenance convenience and efficiency.

[0006] The technical solution is as follows: A fault location device for power equipment includes: a base; mounting seats fixedly connected to the left and right sides of the base; a bidirectional lead screw rotatably connected to the mounting seats, with the threads on both sides of the bidirectional lead screw having opposite directions; a handle fixedly connected to the end of the bidirectional lead screw, the handle being located outside the mounting seats; clamping plates slidably connected to the mounting seats, each mounting seat having two clamping plates slidably connected, the clamping plates being displaced in a back-and-forth direction, the two clamping plates on the same mounting seat respectively engaging with the threads on both sides of the bidirectional lead screw having different directions of rotation; a support plate disposed on the mounting seats, the support plate being disposed on the upper part of the mounting seats; an adjusting screw rotatably connected to the support plate, the adjusting screw being threadedly connected to the mounting seats; and a guide rod fixedly connected to the lower part of the support plate, the guide rod being slidably connected to the mounting seats.

[0007] Optionally, it further includes: a limiting unit disposed on the clamp plate, the limiting units being distributed in an array on the side of the clamp plate that contacts the cable, the limiting unit including: a sleeve fixedly connected to the clamp plate; a push rod slidably connected to the sleeve, the push rod sliding along the axial direction of the sleeve; and a return spring fixedly connected between the push rod and the sleeve.

[0008] Optionally, it also includes: an anti-wear pad fixedly connected to the support plate, the anti-wear pad being disposed on the upper surface of the support plate.

[0009] Optionally, it also includes a corrugated sleeve that is fixedly connected between the support plate and the mounting base.

[0010] Optionally, it also includes: a directional marker fixedly connected to the support plate.

[0011] Optionally, it also includes: a height marking fixedly attached to the clamp.

[0012] The beneficial effects of this utility model are as follows: By using a cable clamp and support plate that can center the cable, this utility model achieves stable fixation of the cable on the mounting base and ensures that the two cable sections are precisely aligned with the center positions of the clamp and mounting base, thus providing a precise docking reference for subsequent connection processes. This utility model uses an array of distributed limiting units, which automatically adjust their contact positions according to the cable's outer diameter. Through multi-point elastic constraints, cable displacement is effectively limited, improving the overall stability of the clamp's fixation of the cable and ensuring precise docking operations. Auxiliary designs such as anti-wear pads, corrugated sheaths, direction markings, and height markings further optimize the safety and ease of operation of this utility model.

Detailed Implementation

[0018] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0019] Example: A fault location device for power equipment, see reference. Figures 1-3 The system includes: a base 1; mounting seats 2 fixedly installed on the left and right sides of the base 1; a bidirectional lead screw 3 rotatably installed inside the mounting seats 2, with the threads on both sides of the bidirectional lead screw 3 having opposite directions; a handle 4 fixedly installed at the end of the bidirectional lead screw 3, the handle 4 being located outside the mounting seats 2; a clamping plate 5 slidably installed on the mounting seats 2, with two clamping plates 5 slidably installed on each mounting seat 2, the clamping plates 5 moving in a back-and-forth direction, and the two clamping plates 5 on the same mounting seat 2 respectively engaging with the threads on both sides of the bidirectional lead screw 3 with different directions; a support plate 6 set on the mounting seats 2, the support plate 6 being located at the upper part of the mounting seats 2; an adjusting screw 7 rotatably installed on the support plate 6, the adjusting screw 7 being threadedly installed with the mounting seats 2; and a guide rod 8 fixedly installed at the lower part of the support plate 6, the guide rod 8 being slidably installed with the mounting seats 2, the adjusting screw 7 cooperating with the guide rod 8 to achieve vertical displacement of the support plate 6.

[0020] Place the two cable segments to be connected on the mounting bases 2 on both sides. First, adjust the height of the support plates 6 on both sides by rotating the adjusting screw 7 so that when the cable is placed on the support plate 6, the center line of the cable is aligned with the center of the clamping plate 5. Then, use the handle 4 to rotate the double-acting screw 3 to control the two clamping plates 5 to move synchronously towards the center and firmly clamp the cable. At this time, the device not only achieves stable fixation of the cable on the mounting base 2, but also ensures that the two cable segments are accurately aligned with the center position of the clamping plate 5 and the mounting base 2, thereby providing a precise docking reference for subsequent connection processes.

[0021] See Figure 1 and Figure 4 It also includes: a limiting unit disposed on the clamping plate 5, the limiting unit being used to adapt to the cable shape structure to enhance the clamping stability of the clamping plate 5, the limiting unit being distributed in an array on the side of the clamping plate 5 in contact with the cable, the limiting unit including: a sleeve 9 fixedly mounted on the clamping plate 5; a push rod 10 slidably mounted on the sleeve 9, the push rod 10 sliding along the axial direction of the sleeve 9; and a return spring 11 fixedly mounted between the push rod 10 and the sleeve 9.

[0022] When the clamping plate 5 moves to clamp the cable, the limiting unit will first contact the cable. During this process, under the pressure of contact with the cable, the push rod 10 will retract along the inner cavity of the sleeve 9 and compress the return spring 11 until the clamping plate 5 completes the final clamping. Therefore, the limiting unit can dynamically adjust the contact position according to the outer diameter of the cable, and effectively limit the cable displacement through multi-point elastic constraints, thereby improving the overall fixing stability of the cable by the clamping plate 5 and providing a guarantee for subsequent precise docking operations.

[0023] See Figure 1 and Figure 2 It also includes: an anti-wear pad 12 fixedly installed on the support plate 6, the anti-wear pad 12 being disposed on the upper surface of the support plate 6 to reduce contact wear with the cable and ensure the integrity of the cable surface; a corrugated sheath 13 fixedly installed between the support plate 6 and the mounting base 2, the corrugated sheath 13 being used to prevent foreign objects from entering the space below the support plate 6 and ensuring the safety of the support plate 6 in use; a direction mark 14 fixedly installed on the support plate 6, the direction mark 14 clearly indicating the rotation direction of the adjusting screw 7 to facilitate the adjustment operation of the support plate 6; and a height mark 15 fixedly installed on the clamping plate 5, the height mark 15 visually displaying the height position of the support plate 6, making the centering positioning of the cable more convenient; both the direction mark 14 and the height mark 15 are used to improve the operational convenience of this device.
