Description

Technical Field

[0001] This utility model belongs to the field of power operation and maintenance technology, and in particular relates to a fault location device for power transmission and transformation lines. Background Technology

[0002] As critical channels for power transmission, the safe and stable operation of power transmission lines directly impacts the reliability of power supply. With the continuous expansion of the power grid coverage, the environment in which power transmission lines operate is becoming increasingly complex, leading to a corresponding increase in the probability of faults. Rapid and accurate fault location and timely repair are core requirements for ensuring the continuous operation of the power system, and power transmission line fault location devices are crucial equipment for achieving this.

[0003] Chinese patent application CN216751124U discloses an installation structure for a transmission line fault location device, including a device housing and angle steel fasteners. The housing is positioned against the angle steel at the required fixing location on the transmission line tower. The side lugs of the housing are secured to the angle steel using symmetrically arranged angle steel fasteners on both sides of the device. This invention offers the following advantages: The fault location device can be securely fixed to the tower angle steel, and installation is simple, requiring only four bolts to attach it to the flat side of the angle steel.

[0004] While the installation structure of the aforementioned equipment can solve the installation problem, in actual operation, it requires on-site personnel to assemble and debug multiple components, which is quite cumbersome. Taking the bolt fixing method as an example, a lot of time needs to be spent finding suitable bolts and aligning the mounting holes, and multiple tools such as wrenches need to be used to tighten them step by step. This not only consumes manpower, but also easily leads to a decrease in installation accuracy due to improper operation. At the same time, it lacks an air intake cleaning function, and the air intake is easily blocked, affecting the heat dissipation effect, which in turn leads to a shortened service life of the internal components of the device due to high temperature.

[0005] To address these issues, we provide a fault location device for power transmission and transformation lines. Utility Model Content

[0006] The purpose of this utility model is to provide a fault location device for power transmission and transformation lines. By combining a rapid positioning mechanism and an air intake cleaning mechanism, it solves the problems of the prior art, which uses bolt fixing, which is labor-intensive, prone to improper operation leading to decreased installation accuracy, and lacks air intake cleaning function.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a fault location device for power transmission and transformation lines, comprising a chassis. A quick positioning mechanism is fixedly connected to the rear end of the chassis, and an air intake cleaning mechanism is provided at the bottom of the chassis. The quick positioning mechanism includes mounting brackets and structural steel. Two mounting brackets are provided, one side of which is fixedly connected to the chassis. The two mounting brackets are positioned on both sides of the structural steel. A connecting plate is fixedly connected to one side of each mounting bracket, and a threaded rod is threaded into the inner cavity of the connecting plate. A movable plate is movably connected to one side of the threaded rod via a bearing. Two clamping rods are fixedly connected to one side of the movable plate. A spring is fixedly connected to one side of each mounting bracket, and one side of the spring is fixedly connected to the movable plate. The top and bottom of the structural steel are provided with clamping holes for use with the clamping rods. The two mounting brackets are symmetrically distributed on both sides of the structural steel, forming a stable clamping space to ensure that the structural steel is firmly clamped and not prone to lateral displacement. The threaded rods are threaded into the connecting plate. The connection method allows the rotating threaded rod to drive the movable plate horizontally via threaded transmission. Two locking rods are arranged vertically, corresponding to locking holes. When the movable plate moves, the locking rods simultaneously insert or retract from the locking holes, enabling rapid locking and unlocking of the device and the steel profile. When the spring between the mounting bracket and the movable plate is in its natural state, it can apply a certain pushing force to the movable plate, keeping the locking rods inserted into the locking holes and enhancing the reliability of the lock. When unlocking is required, rotating the threaded rod in the opposite direction overcomes the spring force, causing the movable plate to move and the locking rods to retract from the locking holes. This significantly improves installation and disassembly efficiency, making it particularly suitable for time-sensitive scenarios such as emergency repairs of power transmission and transformation lines. The multiple locking holes on the steel profile allow the device to be adjusted in position according to actual needs, enhancing installation flexibility. The spring force ensures a tight fit between the locking rods and the locking holes, preventing loosening due to vibration in strong winds or other outdoor environments, thus guaranteeing installation stability.

[0009] The present invention is further configured such that the air intake cleaning mechanism includes an air intake hood, the top of which is connected to the chassis, and sliding grooves are provided at both the front and rear ends of the air intake hood. A movable frame is slidably connected to the surface of the sliding grooves, and a cleaning brush is fixedly connected to one side of the movable frame. An air intake groove is provided at the bottom of the air intake hood, and one side of the cleaning brush contacts the air intake groove. The air intake hood is connected to the chassis to provide a channel for air to enter. The cleaning brush cleans the air intake groove by sliding the movable frame, effectively preventing dust from clogging the air intake groove, ensuring smooth air intake, and completing the cleaning without disassembling the air intake hood, thus reducing the difficulty of maintenance.

[0010] The present invention is further configured such that mounting holes are provided on both sides of the inner cavity of the steel profile, the locking holes are equidistantly distributed, and one side of the locking rod extends into the inner cavity of the locking hole. The mounting holes facilitate fixing the steel profile to different towers, enhancing the versatility of the device installation. The equidistant distribution of the locking holes facilitates the selection of a suitable installation position according to actual needs.

[0011] The present invention is further configured such that a connecting block is fixedly connected to the top of the chassis, and a protective plate is fixedly connected to the top of the connecting block. The protective plate can effectively block direct sunlight and rain, reduce the excessively high internal temperature of the chassis caused by sun exposure, and prevent direct rainwater splashing from corroding the surface of the chassis and internal components, thereby extending the service life of the device.

[0012] The present invention is further provided that a handwheel is fixedly connected to the top of the threaded rod, and the surface of the handwheel is provided with anti-slip texture. The handwheel facilitates the operator to rotate the threaded rod, thereby improving the efficiency of installation and adjustment.

[0013] The present invention is further configured such that grooves are provided on both sides of the chassis, and heat dissipation slots are provided in the inner cavity of the grooves. Protective covers are fixedly connected to both sides of the chassis. The heat dissipation slots increase the heat dissipation area of ​​the chassis, which is conducive to the dissipation of internal heat. The protective covers further prevent dust from entering the chassis through the heat dissipation slots.

[0014] The present invention is further configured such that one side of the mounting bracket is fixedly connected to the chassis by bolts, and the distance between the mounting brackets is adapted to the width of the steel section, so as to ensure that the steel section can be stably clamped, avoid gaps between the mounting bracket and the steel section that would cause the device to shake, and ensure the stability of the overall structure.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model utilizes two mounting brackets to clamp the steel profile. Rotating the threaded rod moves the movable plate, allowing the clamping rod to insert into or disengage from the clamping hole in the steel profile. Combined with the elastic reset effect of the spring, this enables rapid fixing and separation of the device from the steel profile. The equidistant distribution of the clamping holes allows for flexible adjustment of the device's installation position on the steel profile. Position calibration can be completed without disassembling the overall structure, significantly improving installation and adjustment efficiency. The steel profile can be adapted to different specifications of poles and towers through the mounting holes, enhancing the device's adaptability to different installation scenarios and reducing the need for customized components.

[0017] 2. When the movable frame slides along the slide groove, the cleaning brush cleans the air inlet groove in real time, effectively preventing dust from clogging the air inlet and ensuring air circulation and heat dissipation inside the device. The cleaning process does not require disassembling the air inlet cover and can be completed by pushing the movable frame, which reduces the difficulty of maintenance, avoids downtime caused by cleaning, and ensures the continuous operation of the fault location device.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-5 This utility model is a fault location device for power transmission and transformation lines, including a chassis 1. A quick positioning mechanism 2 is fixedly connected to the rear end of the chassis 1. An air intake and cleaning mechanism 3 is provided at the bottom of the chassis 1. The quick positioning mechanism 2 includes a mounting frame 21 and a steel section 22. There are two mounting frames 21. One side of the mounting frame 21 is fixedly connected to the chassis 1. The two mounting frames 21 are set on both sides of the steel section 22. A connecting plate 23 is fixedly connected to one side of the mounting frame 21. A threaded rod 24 is threadedly connected to the inner cavity of the connecting plate 23. A movable plate 25 is movably connected to one side of the threaded rod 24 through a bearing. A locking rod 26 is fixedly connected to one side of the movable plate 25. There are two locking rods 26. A spring 27 is fixedly connected to one side of the mounting frame 21. One side of the spring 27 is fixedly connected to the movable plate 25. The top and bottom of the steel section 22 are provided with locking holes 28 for use with the locking rods 26.

[0028] Specifically: Two mounting brackets 21 are symmetrically distributed on both sides of the steel profile 22, forming a stable clamping space to ensure that the steel profile 22 can be firmly clamped and is not prone to lateral displacement. The threaded connection between the threaded rod 24 and the connecting plate 23 allows the movable plate 25 to move horizontally through the threaded transmission when the threaded rod 24 is rotated. Two locking rods 26 are distributed vertically and correspond to the locking holes 28. When the movable plate 25 moves, the locking rods 26 simultaneously insert or exit the locking holes 28, realizing the rapid locking and unlocking of the device and the steel profile 22. When the spring 27 between the mounting bracket 21 and the movable plate 25 is in its natural state, it can apply a certain pushing force to the movable plate 25 to keep the locking rods 26 in place. The device is held in the position of the insertion hole 28, which enhances the reliability of the locking. When unlocking is required, the threaded rod 24 is rotated in the opposite direction to overcome the elastic force of the spring 27, which drives the movable plate 25 to move, causing the locking rod 26 to disengage from the locking hole 28. This greatly improves the efficiency of installation and disassembly, and is especially suitable for scenarios with high time requirements, such as emergency repair of power transmission and transformation line faults. The multiple locking holes 28 on the steel profile 22 allow the device to be adjusted on the steel profile 22 according to actual needs, which enhances the flexibility of the device installation. The elastic force of the spring 27 ensures the tight fit between the locking rod 26 and the locking hole 28, preventing the device from loosening due to vibration in environments such as strong winds in the field, and ensuring the stability of the installation.

[0029] Example 2

[0030] Please see Figure 1-5 Based on Embodiment 1, the air intake cleaning mechanism 3 includes an air intake hood 31. The top of the air intake hood 31 is connected to the chassis 1. Slide grooves 32 are provided at both the front and rear ends of the air intake hood 31. A movable frame 33 is slidably connected to the surface of the slide grooves 32. A cleaning brush 34 is fixedly connected to one side of the movable frame 33. An air intake groove 35 is provided at the bottom of the air intake hood 31. One side of the cleaning brush 34 contacts the air intake groove 35. Mounting holes 4 are provided on both sides of the inner cavity of the steel profile 22. The locking holes 28 are equidistantly distributed. One side of 26 extends into the inner cavity of the card hole 28. A connecting block is fixedly connected to the top of the chassis 1, and a protective plate 5 is fixedly connected to the top of the connecting block. A handwheel 6 is fixedly connected to the top of the threaded rod 24. The surface of the handwheel 6 is provided with anti-slip texture. Grooves 7 are provided on both sides of the chassis 1. Heat dissipation slots 8 are provided in the inner cavity of the grooves 7. Protective covers 9 are fixedly connected to both sides of the chassis 1. One side of the mounting bracket 21 is fixedly connected to the chassis 1 by bolts. The distance between the mounting brackets 21 is adapted to the width of the steel profile 22.

[0031] Specifically: the air intake shroud 31 connects to the chassis 1 to provide a channel for air intake. The cleaning brush 34 cleans the air intake slot 35 via the sliding frame 33, effectively preventing dust from clogging the air intake slot 35 and ensuring smooth air intake. Cleaning can be completed without disassembling the air intake shroud 31, reducing maintenance difficulty. The mounting holes 4 facilitate fixing the steel profile 22 to different towers, enhancing the versatility of the device installation. The equally spaced locking holes 28 allow for selection of suitable installation positions according to actual needs. The protective plate 5 effectively blocks direct sunlight and rain, reducing the internal temperature of the chassis 1 caused by sun exposure. Excessive heat and direct rain splashing can corrode the surface and internal components of the chassis 1, extending the service life of the device. The handwheel 6 allows operators to easily rotate the threaded rod 24, improving the efficiency of installation and adjustment. The heat dissipation slot 8 increases the heat dissipation area of ​​the chassis 1, which is conducive to the dissipation of internal heat. The protective cover 9 further prevents dust from entering the chassis 1 through the heat dissipation slot 8. The distance between the mounting brackets 21 is adapted to the width of the steel profile 22, ensuring that the steel profile 22 can be stably clamped and avoiding gaps between the mounting brackets 21 and the steel profile 22 that could cause the device to shake, thus ensuring the stability of the overall structure.

[0032] The working principle of this utility model is as follows: the steel profile 22 is fixed on the tower of the power transmission line through the mounting hole 4, and two mounting brackets 21 are clamped on both sides of the steel profile 22. The operator turns the handwheel 6, and the handwheel 6 drives the movable plate 25 to move horizontally through the threaded rod 24. The locking rod 26 moves synchronously with the movable plate 25. When the locking rod 26 is aligned with the locking holes 28 at the top and bottom of the steel profile 22, the device is quickly locked to the steel profile 22. The whole process does not require disassembling a large number of parts, which can meet the needs of rapid installation in emergency scenarios such as fault repair.

[0033] When dust accumulates on the surface of the air intake slot 35, the operator pushes the moving frame 33 to slide along the slide 32. The moving frame 33 drives the cleaning brush 34 to move synchronously. The cleaning brush 34 contacts the surface of the air intake slot 35 and cleans it. The cleaning can be completed without disassembling the air intake cover 31, thus maintaining the heat dissipation effect.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
