Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of cable fault detection, and more specifically, to a detection device for cable fault detection. Background Technology

[0002] In the fields of power distribution and communication networks, cable fault detection is a crucial link in ensuring the stable operation of lines. When cables experience faults such as short circuits, open circuits, or insulation aging, detection devices (such as time domain reflectometers and step voltage detectors) are needed to locate the fault point for rapid repair and restoration of power or communication. Cables are often laid along roads, green belts, hillsides, and other complex terrains, requiring detection operations to be carried out on uneven ground. However, traditional cable fault detection devices have significant drawbacks, including poor adaptability to ground flatness and inability to provide stable support on sloping surfaces, severely impacting detection accuracy and operational safety. Traditional detection devices often use fixed flat-bottomed supports or simple tripod structures, which are only suitable for level ground. When operating on sloping surfaces, the supports are prone to tilting and shifting: at best, this causes the detection device to deviate from the cable route, resulting in inaccurate signal reception and fault location errors of 1-3 meters, requiring repeated testing; at worst, it can cause the device to tip over, damaging the detection host and even posing a safety hazard of injury to operators.

[0003] Therefore, developing a cable fault detection device that can adapt to sloping roads and has stable support function has become an urgent need for the industry to improve fault location efficiency and operational safety. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a detection device for cable fault detection, which solves the technical problem that traditional cable fault detection devices in the prior art have poor adaptability to ground flatness and cannot provide stable support when there is a slope on the road surface.

[0005] According to one aspect, at least one embodiment of this disclosure provides a detection device for cable fault detection, comprising: A base and an operating device body, wherein the operating device body is mounted on the base; A movable support assembly, wherein the movable support assembly is disposed on the base; The device includes a support frame and a detection component. The support frame is fixed on the base, the main body of the operating instrument is mounted on the support frame, and the detection component is disposed inside the base. The detection component includes a bottom groove, which is formed at the bottom of the base. A threaded groove is formed at the top of the base and is connected to the inside of the bottom groove. A drill bit is provided inside the bottom groove, and an inner cavity is formed inside the drill bit. A sound collector is provided in the inner cavity.

[0006] As a further technical solution, an outer groove is formed around the side surface of the drill bit, and several openings are formed around the inner surface of the outer groove. A barrier net is wrapped inside the outer groove, and a fixing bracket is fitted at both ends of the barrier net.

[0007] As a further technical solution, a rotating seat is rotatably connected to the bottom of the inner cavity, the lower end of the sound collector is inserted into the rotating seat, and a stud is connected to the upper end of the drill bit, which is connected to the threaded groove by a threaded engagement.

[0008] As a further technical solution, the stud has an elongated cavity, through which the connecting wire of the sound collector extends to the outside, and a pair of handles are provided at the upper end of the stud.

[0009] As a further technical solution, the movable support assembly includes a pair of pedals, each with an insertion rod at both ends of its bottom. The insertion rods are movably fitted into the base, and the bottom of the base has several grooves in which movable wheels are installed.

[0022] like Figures 1-4 As shown, a cable fault detection device according to an embodiment of the present disclosure is illustrated, comprising: The base 1 and the main body 2 of the operator device are mounted on the base 1. A movable support assembly 5 is disposed on the base 1; The bracket 3 and the detection component 4 are provided. The bracket 3 is fixed on the base 1, the main body 2 of the operating instrument is installed on the bracket 3, and the detection component 4 is disposed inside the base 1. The detection component 4 includes a bottom groove 4-1, which is formed at the bottom of the base 1. A threaded groove 4-2 is formed at the top of the base 1, and the threaded groove 4-2 communicates with the interior of the bottom groove 4-1. A drill bit 4-3 is installed inside the bottom groove 4-1, and an inner cavity 4-4 is formed inside the drill bit 4-3. A sound collector 4-5 is installed in the inner cavity 4-4. An outer groove 4-6 is formed around the side surface of the drill bit 4-3, and several openings 4-7 are formed around the inner surface of the outer groove 4-6. A barrier net 4 is wrapped inside the outer groove 4-6. -8, both ends of the barrier net 4-8 are fitted with fixed brackets 4-9, the bottom of the inner cavity 4-4 is rotatably connected to a rotating seat 4-10, the lower end of the sound collector 4-5 is inserted into the rotating seat 4-10, the upper end of the drill bit 4-3 is connected to a stud 4-11, the stud 4-11 is connected to the threaded groove 4-2 by threaded engagement, the stud 4-11 has an elongated cavity 4-12, the connecting line of the sound collector 4-5 passes through the elongated cavity 4-12 and extends to the outside, and a pair of handles 4-13 are provided at the upper end of the stud 4-11.

[0023] In some examples, in order to effectively capture and transmit the sound of cable faults under the soil, adapt to the needs of cable detection at different depths, and ensure the accuracy of fault location, a detection component 4 is designed. This component includes a bottom groove 4-1 at the bottom of the base 1 to provide storage space for the drill bit 4-3 and prevent damage to the drill bit 4-3 when not in the detection state; the threaded groove 4-2 at the top of the base 1 is connected to the bottom groove 4-1, and the stud 4-11 at the upper end of the drill bit 4-3 is connected to the threaded groove 4-2 through threaded engagement. The operator can rotate the pair of handles 4-13 at the upper end of the stud 4-11 to drive the stud 4-11 to move vertically up and down along the threaded groove 4-2, thereby driving the drill bit 4-3 to drill into or out of the soil. The drilling depth is precisely controlled through threaded transmission, which is suitable for cable detection scenarios at different burial depths.

[0024] The inner cavity 4-4 inside the drill bit 4-3 provides installation space for the sound acquisition device 4-5. The sound acquisition device 4-5 can capture abnormal vibrations or sound signals generated when the cable is faulty, providing data support for fault location. The rotating seat 4-10 at the bottom of the inner cavity 4-4 is rotatably connected by a bearing. The lower end of the sound acquisition device 4-5 is inserted into the rotating seat 4-10, allowing the sound acquisition device 4-5 to rotate around the rotating seat 4-10. This facilitates the adjustment of the acquisition angle, ensuring that the acquisition device can be accurately aligned with the cable direction and improving the sensitivity of sound signal acquisition.

[0025] A barrier net 4-8 is wrapped inside the outer groove 4-6 around the side surface of the drill bit 4-3. The barrier net 4-8 is fixed inside the outer groove 4-6 by the fixing brackets 4-9 at both ends. It can prevent sand, gravel and impurities in the soil from entering the inner cavity 4-4, and prevent impurities from abrading the sound collector 4-5 or blocking the opening 4-7. Several openings 4-7 are evenly distributed on the inner surface of the outer groove 4-6, which can allow the sound signal of cable fault to pass through the openings 4-7 and be transmitted to the sound collector 4-5 in the inner cavity 4-4, which not only ensures smooth sound transmission, but also plays a protective role.

[0026] The long cavity 4-12 inside the stud 4-11 provides a passage for the connecting wire of the sound acquisition device 4-5. The connecting wire extends through the long cavity 4-12 to the outside and connects to the main body 2 of the operator, so that the acquired sound signal can be transmitted to the main body 2 of the operator for analysis and processing. The sealed design of the long cavity 4-12 can prevent rainwater and mud from entering and damaging the connecting wire, and ensure stable signal transmission.

[0027] During operation, rotating handle 4-13 drives drill bit 4-3 to drill into the soil near the cable; adjusting the angle of sound collector 4-5, the fault sound is captured through port 4-7; the signal is transmitted to the main body 2 of the operating instrument via the connecting cable; after detection, rotating handle 4-13 in the opposite direction retracts drill bit 4-3. Controllable drilling allows for depth adjustment, the barrier net 4-8 and port 4-7 work together for protection and sound transmission, and the rotating base 4-10 enhances the flexibility of data acquisition. All components work together to complete the sound detection of cable faults in the soil, providing reliable data for fault location.

[0028] like Figures 1-4 As shown in the figure, the mobile support assembly 5 in this embodiment includes a pair of pedals 5-1. Each pedal 5-1 has an insertion rod 5-2 at both ends of its bottom. The insertion rod 5-2 is movably fitted into the base 1. The bottom of the base 1 has several grooves 5-3, and a moving wheel 5-4 is installed in each groove 5-3.

[0029] In some examples, in order to achieve flexible movement of the detection device and stable support during detection, avoid displacement of the base 1 during detection that affects detection accuracy, and adapt to the detection needs of complex outdoor terrain, a mobile support component 5 is designed. This component includes a mobile wheel 5-4 installed in the groove 5-3 at the bottom of the base 1. The wheel 5-4 is made of wear-resistant and non-slip material, which allows the entire device to be moved easily by pushing the base 1 without manual handling, reducing the labor intensity of operators. It is especially suitable for scenarios where multiple detection points need to be moved in a large area. The mobile wheel 5-4 can be equipped with a brake function, which can be used to initially fix the device when it is temporarily stopped to prevent it from sliding.

[0030] The insert rod 5-2, which is movable within the base 1, penetrates vertically through the base 1 and is fixedly connected at both ends of the bottom of the pedal 5-1. The pedal 5-1 is horizontally positioned, making it easy for the operator to apply downward pressure by stepping on it. The lower end of the insert rod 5-2 is pointed, allowing it to be inserted into the soil when the pedal 5-1 is stepped on, thus forming a vertical fixation on the base 1 and enhancing the stability of the connection between the base 1 and the ground. The movable fitting structure of the insert rod 5-2 and the base 1 allows the insert rod 5-2 to move vertically along the base 1 as the pedal 5-1 is raised and lowered, adapting to soil layers of different hardness. When the device needs to be moved during operation, the insertion rod 5-2 is retracted into the base 1, and the device is pushed to the target detection point using the moving wheels 5-4. Upon reaching the detection point, the operator steps on the pedal 5-1 to insert the insertion rod 5-2 into the soil layer, simultaneously braking the moving wheels 5-4 to secure it. After detection, the pedal 5-1 is pulled upwards to remove the insertion rod 5-2 from the soil layer, allowing the device to continue moving. The moving wheels 5-4 ensure easy movement, while the insertion rod 5-2 and pedal 5-1 work together to achieve stable fixation. All components work together to support the detection device, ensuring that the base 1 remains fixed to the ground during detection, providing a stable foundation for accurate detection and preventing the drill bit 4-3 from deviating from the target cable or the sound collector 4-5 from its position due to base 1 displacement, which would affect the detection results.

[0031] For example, such as Figure 1 As shown, the surface of the pedal 5-1 has a wavy anti-slip structure, and the lower end of the insertion rod 5-2 has a tapered structure.

[0032] In some examples, the surface of the pedal 5-1 has a wavy, anti-slip structure. This design increases the contact friction between the foot and the pedal 5-1 through the wavy protrusions, effectively preventing the operator's foot from slipping even in outdoor rainy or muddy conditions, ensuring that the downward pressure is stably transmitted to the insertion rod 5-2. The lower end of the insertion rod 5-2 has a conical structure. The conical tip can significantly reduce the resistance when inserting into the soil layer, allowing for easy penetration of both soft soil and soil layers containing a small amount of sand and gravel. At the same time, the contact area between the conical structure and the soil increases with the insertion depth, further improving the stability of the base 1 and preventing the base 1 from shifting due to ground vibration or external force during the detection process, ensuring the accurate correspondence between the drill bit 4-3 and the cable detection position.

[0033] For example, such as Figure 2 As shown, a drill bit holder 6 is provided on the lower end face of the drill bit 4-3.

[0034] In some examples, the drill bit holder 6, located on the lower end face of the drill head 4-3, is made of high-strength alloy material. The holder is radially distributed and can cut and break up the soil layer as the drill head 4-3 rotates and moves downwards. When facing soil layers containing gravel and hard lumps, the drill bit holder 6 can quickly remove obstacles, preventing direct pressure deformation of the lower end face of the drill head 4-3, while reducing the physical exertion of the operator in turning the handle 4-13 and improving drilling efficiency. Furthermore, the cutting action of the holder allows the drill head 4-3 to form a regular drilling channel, preventing soil collapse and blockage of the drilling path, ensuring that the drill head 4-3 can smoothly penetrate to the cable burial depth, and providing a stable soil environment for the sound acquisition device 4-5 to capture fault signals.

[0035] For example, such as Figure 1 As shown, the surface of the handle 4-13 has a frosted, non-slip structure.

[0036] In some examples, the handle 4-13 has a frosted, non-slip surface. This textured surface increases grip friction, allowing operators to maintain a firm grip even with sweaty or muddy hands, preventing slippage that could lead to hand injuries or inaccurate drilling depth control. The frosted surface also improves grip comfort, reducing hand abrasion and fatigue from prolonged use of the handle 4-13. This is especially important in exploration operations requiring multiple depth adjustments, ensuring consistent and stable force application, precise control of the stud 4-11's lifting speed, and ensuring the drill bit 4-3 penetrates the soil to the preset depth. This prevents operational errors from causing deviations in the detection position and affecting fault location accuracy.

[0037] In practical use: Push the base 1 to move the detection device to the suspected cable fault area via the bottom moving wheels 5-4. Step on the pedal 5-1 of the moving support assembly 5 to insert the conical insertion rod 5-2 into the soil layer and fix the position of the base 1. Rotate the handle 4-13 on the stud 4-11 of the detection assembly 4 to drive the drill bit 4-3 down along the bottom groove 4-1 using the threaded engagement. The drill bit holder 6 cuts the soil layer until the drill bit 4-3 reaches near the cable burial depth. Adjust the rotating seat 4-10 inside the inner cavity 4-4 so that the sound collector 4-5 is aligned with the cable direction. The blocking net 4-8 filters sand and gravel impurities, and the cable fault sound is transmitted to the inner cavity 4-4 through the opening 4-7 and collected. The sound signal is transmitted to the main body 2 of the operating instrument through the connecting wire in the long cavity 4-12. The operator analyzes the signal to locate the fault point through the operating instrument. After the exploration is completed, turn the handle 4-13 in the opposite direction to retract the drill bit 4-3, pull up the pedal 5-1 to pull out the insertion rod 5-2, and push the device to the next exploration point. It is adaptable to complex terrain throughout the process to ensure stable and accurate exploration.
