An electrical cable fault point locating device

Abstract

This utility model proposes a fault location device for electrical cables, comprising: a main base and two detectors symmetrically fixedly installed at the center of its top. The top of the main base has grooves at both ends; a rotating shaft is rotatably connected within the grooves and extends through to the outside of the main base; and a concave wheel fixedly installed on the surface of the rotating shaft. The concave wheel rotates via a drive mechanism located on the main base. An electric push rod drives a U-shaped block at the output end to move downwards, simultaneously causing the upper concave wheel to move downwards and approach the lower concave wheel, bringing it into contact with the top surface of the cable. The upper and lower concave wheels then clamp the electrical cable. The electric push rod moves the upper concave wheel up and down for adjustment, thereby adjusting the distance between the upper and lower concave wheels. This avoids situations where the device cannot adapt to electrical cables of different diameters, effectively improving its adaptability and flexibility.

Description

Technical Field

[0001] This utility model relates to the field of electrical cable fault detection technology, specifically to a device for locating electrical cable fault points. Background Technology

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information, and realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, cables refer to insulated cables, which can be defined as: an assembly consisting of one or more insulated conductors, and their respective possible coverings, overall protective layers, and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] A known authorized patent with application number CN202421251334.1 discloses an optical fiber fault location device. Its background technology addresses the problem that "current optical fiber fault detection equipment cannot guarantee smooth operation when encountering cable surfaces covered with ice due to weather conditions, and high-altitude operations are often affected by wind, causing swaying and affecting the device's effectiveness." To address this problem, the technical solution is as follows: "It includes a base plate, a motor mount fixedly connected to the outer surface of the base plate, a motor fixedly connected to the outer surface of the motor mount, an active rotating shaft fixedly connected to the output end of the motor, and concave grooves on both sides of the base plate. The inner surface of the left concave groove is rotatably connected to the outer surface of the active rotating shaft, and the inner surface of the right concave groove is rotatably connected to a driven rotating shaft."

[0004] However, in implementing the relevant technology, the following problems were found with the above technical solution: When in use, it is inconvenient to adjust the distance between the two concave wheels according to the diameter of the wire and cable. The positions of the upper and lower concave wheels are fixed, making it impossible to clamp and fix wires of different diameters, which can easily reduce the scope of application. In addition, it is inconvenient to quickly remove ice from the wire and cable. The above solution removes ice by blowing hot air on the wire and cable, which takes a certain amount of time to melt the ice, and the speed is slow, which can easily reduce the efficiency of wire and cable inspection. Utility Model Content

[0005] This invention proposes a fault location device for electrical cables, which solves the problems of inconvenience in adjusting the distance between the two concave wheels and inconvenience in quickly removing ice from electrical cables in related technologies.

[0006] The technical solution of this utility model is as follows: a cable fault location device, comprising: a main base and two detectors symmetrically fixedly installed at the top center of the main base, wherein grooves are provided at both ends of the top of the main base; A rotating shaft is rotatably connected within the groove and extends through to the outside of the main body base at one end; A concave wheel is fixedly installed on the surface of the rotating shaft, and the concave wheel rotates through a drive mechanism provided on the main body base; A fixing plate that is fixedly installed in the groove; An electric push rod that is fixedly installed on the top of a fixed plate and whose output end moves through the fixed plate; A U-shaped block fixedly connected to one output end of an electric actuator; Rotate the upper concave wheel that is connected inside the U-shaped block and corresponds to the lower concave wheel; Hot air mechanisms located at both ends of the main base for icing heating cables; And an ice-breaking mechanism installed on the hot air mechanism for removing ice from cables.

[0007] Preferably, the drive mechanism includes pulleys fixedly connected to one end of two rotating shafts, a transmission belt tensioned to the surfaces of the two pulleys, and a motor fixedly mounted on one side of the main body base via a bracket, the output end of the motor being connected to a pulley.

[0008] Preferably, the hot air mechanism includes an inner cavity formed inside both ends of the main body base, ventilation slots formed on both sides of the main body base and connected to the inner cavity, a fan fixedly installed on one side of the inner wall of the inner cavity, a heating wire fixedly installed inside the inner cavity and located in front of the fan, an exhaust shell fixedly installed at both ends of the main body base and connected to the inner cavity, an air outlet formed on both sides of the inner wall of the exhaust shell, and a dustproof net fixedly installed inside the air outlet.

[0009] Preferably, the ice-breaking mechanism includes a mounting plate fixedly installed on the top of the exhaust housing, an electric push rod II fixedly installed on the top of the mounting plate and whose output end moves through the mounting plate, a rectangular block fixedly connected to the output end of the electric push rod II, and a striking component disposed within the rectangular block for striking the ice.

[0010] The striking component includes a movable block that is slidably engaged within a rectangular block, a spring that is fixedly installed on the top of the movable block and connected at one end to the rectangular block, a second motor that is fixedly installed on one side of the movable block and whose output end moves through the movable block, and an eccentric cam that is fixedly connected to the output end of the second motor.

[0011] Preferably, the detector is equipped with a marking mechanism for recording fault points.

[0012] The marking mechanism includes a mounting bracket fixedly installed on top of a detector, and marking components mounted on the mounting bracket.

[0013] The working principle and beneficial effects of this utility model are as follows: The electric push rod moves the U-shaped block at the output end downwards, which in turn moves the upper concave wheel downwards towards the lower concave wheel, bringing the upper concave wheel into contact with the top of the cable surface. The upper and lower concave wheels then clamp the cable. The electric push rod moves the upper concave wheel up and down to adjust the distance between the upper and lower concave wheels. This allows for the adjustment of the appropriate spacing for cables of different diameters, avoiding the situation where a fixed spacing between the upper and lower concave wheels cannot accommodate cables of different diameters. This effectively improves the adaptability and flexibility of use.

[0014] The electric push rod 2 drives the rectangular block to rise and fall to adjust its position. Then, the motor 2 drives the eccentric cam to rotate and intermittently tap the cable to remove the heated ice. At the same time, the spring provides elastic cushioning to prevent damage to the cable. This, together with the hot air mechanism, can quickly remove the ice and avoid the slow melting of ice affecting the detection speed, thus effectively improving the efficiency of cable and wire inspection.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1

[0019] Please see Figure 1 - Figure 5 The present invention provides a cable fault location device, comprising: a main base 1 and two detectors 2 symmetrically fixedly installed at the top center of the main base 1, wherein grooves are provided at both ends of the top of the main base 1. A rotating shaft is rotatably connected within the groove and extends through to the outside of the main body base 1 at one end; The concave wheel 3 is fixedly installed on the surface of the rotating shaft, and the concave wheel 3 rotates through the drive mechanism provided on the main body base 1; A fixing plate 4 is fixedly installed in the groove; An electric push rod 5 is fixedly installed on the top of the fixed plate 4 and its output end moves through the fixed plate 4; U-shaped block 6 is fixedly connected to the output end of electric actuator 5; Rotary connection to the U-shaped block 6 and corresponding to the lower concave wheel 3, wherein the surfaces of both the upper concave wheel 7 and the lower concave wheel 3 have rubber anti-slip protrusions; Hot air mechanisms for icing heating cables are located at both ends of the main base 1; And an ice-breaking mechanism installed on the hot air mechanism for removing ice from cables.

[0020] The technical solution provided in this embodiment is as follows: In use, the cable is placed on the concave wheel 3 through the notch on one side of the fixed plate 4, and the U-shaped block 6 at the output end is moved down by the electric push rod 5. At the same time, the upper concave wheel 7 is moved down and close to the lower concave wheel 3 by the U-shaped block 6, so that the upper concave wheel 7 contacts the top of the cable surface. Thus, the upper concave wheel 7 and the lower concave wheel 3 cooperate to clamp the cable. Therefore, the electric push rod 5 drives the upper concave wheel 7 to move up and down to adjust the distance between the upper concave wheel 7 and the lower concave wheel 3. This allows for the adjustment of the appropriate distance for cables of different diameters, avoiding the situation where the fixed distance between the upper concave wheel 7 and the lower concave wheel 3 cannot adapt to cables of different diameters. This effectively improves the adaptability and flexibility of use. After the cable is clamped, the lower concave wheel 3 is driven to rotate by the drive mechanism, and the upper concave wheel 7 is rotated by friction, thereby causing the device to move. During the movement, the detector 2 detects the cable and locates the faulty cable. At the same time, the data is transmitted to the back-end equipment in real time by the controller, thereby achieving the purpose of detecting and locating the cable fault point.

[0021] Furthermore, the drive mechanism includes pulleys 8 fixedly connected to one end of two rotating shafts, a transmission belt 9 tensioned and connected to the surfaces of the two pulleys 8, and a motor 10 fixedly mounted on one side of the main body base 1 via a bracket. The output end of the motor 10 is connected to a pulley 8.

[0022] Specifically, when the upper concave wheel 7 moves down and the lower concave wheel 3 clamps the cable, the motor 10 drives one pulley 8 to rotate, and under the action of the transmission belt 9, it drives another pulley 8 to rotate synchronously, so that the two lower concave wheels 3 rotate synchronously. This, in conjunction with the rotation of the upper concave wheel 7, causes the device to move along the surface of the cable, so as to detect the movement of the cable.

[0023] Furthermore, the hot air mechanism includes an inner cavity opened inside both ends of the main body base 1, ventilation slots opened on both sides of the main body base 1 and connected to the inner cavity, a fan 11 fixedly installed on one side of the inner wall of the inner cavity, a heating wire 12 fixedly installed inside the inner cavity and located in front of the fan 11, an exhaust shell 13 fixedly installed at both ends of the main body base 1 and connected to the inner cavity, an air outlet opened on both sides of the inner wall of the exhaust shell 13, and a dustproof net 14 fixedly installed in the air outlet.

[0024] Specifically, the fan 11, in conjunction with the ventilation slot, blows air into the exhaust casing 13, and the air blown out by the fan 11 is heated by the heating wire 12. This allows the hot air to be blown onto the cable through the air outlet, which facilitates the heating of the ice on the cable surface, melting and loosening the ice for easy removal, thus ensuring the mobility of the device.

[0025] Furthermore, the ice-breaking mechanism includes a mounting plate 15 fixedly installed on the top of the exhaust housing 13, an electric push rod 16 fixedly installed on the top of the mounting plate 15 and whose output end moves through the mounting plate 15, a rectangular block 17 fixedly connected to the output end of the electric push rod 16, and a striking component disposed in the rectangular block 17 for striking the ice.

[0026] The striking component includes a movable block 18 that is slidably engaged within a rectangular block 17, a spring 19 that is fixedly mounted on the top of the movable block 18 and connected at one end to the rectangular block 17, a motor 20 that is fixedly mounted on one side of the movable block 18 and whose output end moves through the movable block 18, and an eccentric cam 21 that is fixedly connected to the output end of the motor 20.

[0027] Specifically, when removing ice from the cable, the electric push rod 16 moves the rectangular block 17 down to a suitable position. When the hot air mechanism heats the ice on the cable, the motor 20 drives the eccentric cam 21 to rotate. The eccentric action of the eccentric cam 21 intermittently taps the cable to remove the heated ice. At the same time, during the tapping, the eccentric cam 21 can drive the movable block 18 to move upward within the rectangular block 17 and compress the spring 19, allowing the spring 19 to provide elastic buffering and prevent damage to the cable. This, combined with the hot air mechanism, can quickly remove the ice, avoiding the slow melting of ice from affecting the detection speed and effectively improving the efficiency of cable inspection. Example 2

[0028] Based on Example 1, in this example: the detector 2 is equipped with a marking mechanism for recording fault points.

[0029] The marking mechanism includes a mounting bracket 22 fixedly mounted on the top of a detector 2, and a marking component 23 mounted on the mounting bracket 22. The marking component 23 consists of an electric actuator or cylinder mounted on the mounting bracket 22 and a pigment box connected to the output end of the electric actuator. This is prior art disclosed in the art, and for details, please refer to the authorized utility model with publication number CN213122242U.

[0030] The technical solution provided in this embodiment is as follows: when a fault is detected at a certain location of the cable, the marking component 23 marks the location so that subsequent maintenance personnel can repair it.

[0031] It should be noted that a controller is installed on one side of the main base 1 to receive signals from the backend equipment, facilitating the control of the electrical components on this device and transmitting detection data to the backend equipment. Furthermore, a battery is installed inside the main base 1 to power the electrical components on this device, ensuring its operation. This is prior art disclosed in this field and will not be described in detail here.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
