Description

Technical Field

[0001] This invention relates to the technical field of power line damage detection devices, and more particularly to a power line damage detection device. Background Technology

[0002] Currently, power line damage detection widely adopts visual sensors and infrared sensing equipment to monitor line conditions. By relying on imaging recognition and temperature detection methods, potential line damage hazards such as broken conductor strands, damaged hardware, insulation deterioration, and overheated joints can be identified. This enables large-scale line inspection operations and effectively reduces the operational risks of manual tower climbing inspections.

[0003] However, line inspection sensors are often deployed outdoors at poles, monitoring stations, and other locations, making them highly susceptible to interference from complex and harsh weather conditions, which makes it difficult to guarantee detection stability and accuracy. During heavy rain, snow, or fog, water vapor, snow particles, and fog suspended in the air can obstruct the light path, directly causing blurred images captured by visual sensors, making it impossible to clearly identify minor line damage or component defects. At the same time, drastic changes in ambient temperature and humidity can also interfere with the infrared sensor detection benchmark, causing significant deviations in temperature measurement data, making it difficult to accurately distinguish between normal temperature rise and abnormal overheating due to faults, and easily leading to misdiagnosis of faults.

[0004] When low temperatures and icing occur, the ice layer directly covers and blocks the sensor's detection surface, obstructing the reception of light and heat signals. This causes the sensing equipment to completely lose its detection capability, directly interrupting and rendering line damage detection ineffective. Furthermore, strong winds cause the towers and sensor supports to sway continuously, resulting in severe vibrations of the sensors. This leads to abnormal distortions in the acquired image data, temperature signals, and vibration waveforms, generating numerous invalid and false detection signals. This significantly increases the probability of false alarms and fails to accurately reflect the actual operational damage status of the power lines. Summary of the Invention

[0028] Example 1

[0029] Reference Figures 1-5 The first embodiment of the present invention provides a detection mechanism 100 and a heating mechanism 200, which realize basic detection functions and have waterproof and anti-icing functions.

[0030] The testing mechanism 100 includes a mounting box 101, inside which a detector 110 is installed. A mounting cover 102 is located on the left side of the mounting box 101, and a testing port 103 is opened on the left side of the mounting cover 102. A mating member 104 is fixedly connected to both the front and back of the mounting cover 102. A stud 105 is inserted into the right side of the outer side of the mating member 104. The inner side of the stud 105 is fixedly connected to the surface of the mounting box 101, and a threaded sleeve 106 is threaded onto the outer surface of the stud 105. T-shaped strips are fixedly connected to both the front and back of the detector 110. 108. T-slots 109 are provided on the front and rear sides of the inner wall of the mounting box 101. The surface of the T-slot 108 is slidably connected to the inner wall of the T-slot 109. The heating mechanism 200 includes an electric heating ring 201, which is sleeved on the surface of the detection end of the detector 110. Electric heating rods 202 are fixedly connected to the top and bottom of the electric heating ring 201. The outer side of the electric heating rods 202 is electrically connected to an external power source. A drainage groove 203 is provided at the bottom of the inner wall of the detection port 103. Several drainage grooves 203 are provided and are distributed in an arc shape at equal intervals.

[0031] Specifically, the mounting cover 102 and the mounting box 101 are quickly connected and locked by the stud 105 and the sleeve 106, ensuring good assembly sealing and effectively preventing rainwater and dust from entering the equipment, thus protecting the precision components of the detector 110. The detector 110 is embedded in the mounting box 101 by sliding the T-slot 109 on the inner wall of the mounting box 101 with the T-slot 108, enabling precise alignment and constraining the detector 110 in both the lateral and longitudinal directions, preventing misalignment and loosening during long-term operation, and ensuring that the detection optical path is always aligned with the detection port 103. The electric heating ring 201 is precisely fitted onto the detection imaging end of the detector 110, allowing targeted heating of the lens optical area, abandoning the traditional overall heating method. This not only meets the needs of defogging and de-icing but also avoids unnecessary energy consumption. The array-shaped arc-shaped drainage grooves 203 at the bottom of the detection port 103 can quickly guide water accumulated during rain and snow, as well as melted ice, leaving no water residue and preventing secondary condensation, icing, and fogging from the source.

[0032] Furthermore, after the overall equipment is assembled, the detector 110 performs power line imaging and temperature damage detection through the detection port 103. When there is low temperature, fog, rain, snow, or frost outdoors, the external power supply is turned on, the electric heating rod 202 is energized and heated, and the heat is transferred to the electric heating ring 201. The electric heating ring 201 continuously heats the lens area of ​​the detector 110 at a constant temperature, raising the lens surface temperature to above the dew point temperature, eliminating water mist, frost, and ice on the lens surface in real time, and always keeping the detection light path transparent. The water and meltwater generated during the operation will automatically flow into the arc-shaped drainage groove 203 and be quickly discharged outward along the arc of the groove, continuously ensuring that the detection port 103 is not blocked by water accumulation.

[0033] It should be noted that the electric heating ring 201 adopts a localized focused heating design, which only acts on the optical detection area of ​​the detector 110. It will not cause thermal damage to components with poor high-temperature resistance, such as the internal circuit board and sensor chip of the detector 110, thus ensuring higher equipment operating safety. Compared with a straight drainage structure, the arc-shaped equidistant drainage channels 203 have a faster drainage flow rate and no dead corners for water accumulation, making them suitable for large water volume conditions such as heavy rain and ice melting. The T-shaped sliding assembly structure is easy to disassemble and assemble, and the detector 110 can be repaired and replaced without disassembling the entire device, greatly reducing the difficulty of operation and maintenance.

[0034] Example 2

[0035] Reference Figures 1-5 In the second embodiment of the present invention, a shock-absorbing mechanism 300 and a heat dissipation mechanism 400 are provided to achieve detection accuracy in strong wind environments and simultaneously improve heat dissipation effect.

[0036] The shock absorption mechanism 300 includes two airbags 301. The outer side of each airbag 301 is fixedly connected to the inner wall of the mounting box 101. The airbags 301 are located at the top and bottom of the detector 110. Thermally conductive copper rods 302 are provided on the front and rear sides of the interior of each airbag 301. The left side of each thermally conductive copper rod 302 extends through to the left side of the airbag 301. The left side of the inner side of each thermally conductive copper rod 302 is fixedly connected to the surface of the electric heating rod 202. A heat insulation sleeve 107 is fitted on the left side of the surface of each thermally conductive copper rod 302 to reduce heat loss during transfer. A copper mesh 304 is provided inside each airbag 301. The surface of the copper mesh 304 is fixedly connected to the inner side of the thermally conductive copper rods 302. The thermally conductive copper rods 302 are used to transfer heat from the electric heating rod 202 to the interior of the airbag 301 for heating. The copper mesh 304 is used to increase the heating area of ​​the air inside the airbag 301. A one-way air intake valve 303 is fixedly connected to the left side of the outer side of the airbag 301. The outer side of the one-way air intake valve 303 extends to the top and bottom of the mounting box 101. The heat dissipation mechanism 400 includes a heat exhaust groove 401, which is opened at the top right side of the mounting box 101. An air inlet groove 402 is opened at the bottom right side of the mounting box 101. Several air inlet grooves 402 are opened and are evenly distributed. Three pressure relief valves 403 are provided on the left side of the heat exhaust groove 401. The top and bottom of the pressure relief valves 403 are connected to conduits 404. The other end of the conduits 404 is connected to the airbag 301. The pressure relief valves 403 are adjustable. The heat exhaust groove 401 and the air inlet groove 402 cooperate to form air convection heat dissipation.

[0037] Specifically, the excess heat generated by the electric heating rod 202 is utilized for secondary heat utilization. The heat is directed into the airbag 301 via a heat-conducting copper rod 302 with a heat-insulating sleeve 107. The heat-insulating sleeve 107 effectively reduces heat loss along the transmission path, ensuring efficient heat utilization. The copper mesh 304 inside the airbag 301 significantly increases the heat-receiving contact area, allowing the air inside the airbag 301 to heat up more evenly and faster, ensuring rapid and stable expansion of the airbag 301. The upper and lower sets of airbags 301 symmetrically clamp the detector 110, forming a flexible buffer support structure that can counteract equipment vibration caused by strong winds and tower vibrations. The system addresses issues such as blurred images and data distortion caused by vibration. The one-way air inlet valve 303 automatically replenishes air when the air pressure in the airbag 301 is insufficient, maintaining the basic expansion reference amount of the airbag 301. At the same time, it can prevent external moisture and dust from entering the airbag 301. The adjustable pressure relief valve 403 can flexibly set the pressure relief threshold according to outdoor temperature and wind conditions. After the airbag 301 is over-pressurized and discharged, the airflow is introduced into the cavity of the mounting box 101. Together with the bottom air inlet slot 402 and the top heat exhaust slot 401, a stable bottom-up air convection is formed, which can quickly remove the residual heat and redundant heating heat of the equipment, and avoid the damage of precision components caused by high temperature accumulation inside the equipment.

[0038] Furthermore, while the heating mechanism 200 is working to defrost and defog, the residual heat generated by the electric heating rod 202 is rapidly conducted to the interior of the airbag 301 via the heat-conducting copper rod 302. The copper mesh 304 conducts heat throughout, causing the air inside the airbag 301 to rapidly expand. The expanded airbag 301 tightly adheres to the inner wall of the mounting box 101 and the outer wall of the detector 110, forming a flexible, all-around clamping and limiting effect on the detector 110, effectively reducing equipment displacement and vibration caused by strong outdoor winds, light wind vibrations of the lines, and tower swaying. As the heat conduction continues, the air pressure inside the airbag 301 continuously increases. When the air pressure reaches a certain level... When the pressure relief valve 403 reaches the preset threshold, it automatically opens, and the high-pressure gas inside the airbag 301 is discharged into the internal cavity of the mounting box 101 through the conduit 404. The high-pressure hot gas inside the cavity is quickly discharged from the top heat exhaust groove 401, while the ambient cold air is automatically replenished into the cavity from the bottom air inlet groove 402, forming a continuous air convection heat dissipation, which removes the heat accumulated inside the equipment in real time. When the air pressure of the airbag 301 is depressurized to the safety threshold, the pressure relief valve 403 automatically closes, and the airbag 301 remains in a stable inflated state to continuously reinforce the detector 110.

[0039] It should be noted that the airbag 301 is made of highly elastic and weather-resistant material. The flexible clamping and fixing method will not rigidly compress the detector 110 housing and internal components, eliminating the risk of mechanical damage and making it suitable for long-term outdoor reciprocating vibration conditions. The pressure relief valve 403 has an adjustable threshold. In low-temperature winters, the pressure relief threshold can be increased to maintain sufficient air pressure in the airbag 301 to ensure a reinforced and shock-absorbing effect. In high-temperature summers, the threshold can be decreased to improve exhaust heat dissipation efficiency, making it suitable for different working conditions in all seasons. The one-way air intake valve 303 allows air to enter in only one direction and seals in the reverse direction, ensuring that the airbag 301 is sealed and clean throughout the process, preventing dust and water from entering the airbag 301, which can lead to aging failure and expansion jamming. The waste heat reuse structure does not require additional heating equipment to drive the airbag 301, resulting in low energy consumption and high integration.

[0040] The remaining structure is the same as that in Example 1.

[0041] Example 3

[0042] Reference Figures 1-5 This is the third embodiment of the present invention, which differs from the second embodiment in that it provides a power line damage detection device.

[0043] During normal operation, the detector 110 continuously performs damage detection operations such as appearance and temperature checks on power lines through the detection port 103 on the left side of the mounting cover 102. The limiting cooperation between the T-shaped strip 108 and the T-shaped groove 109 ensures that the detector 110 has a precise detection position without deviation or shaking, guaranteeing basic detection accuracy. In foggy, rainy, or low-temperature weather conditions, the equipment activates the heating mechanism 200, and the electric heating ring 201 continuously heats the detection lens of the detector 110 at a constant temperature, preventing lens condensation, icing, and frosting. The arc-shaped drainage groove 203 of the measuring port 103 quickly drains away accumulated water and melt water, keeping the detection optical path unobstructed. The excess heat generated by the electric heating rod 202 is directionally conducted to the interior of the upper and lower airbags 301 through the heat-conducting copper rod 302 with heat insulation sleeve 107. Combined with the all-area heat conduction effect of the copper mesh 304, the airbags 301 expand rapidly and evenly, flexibly and tightly fixing the detector 110, offsetting the equipment vibration caused by strong outdoor winds and tower vibrations, and completely solving the problems of image blurring, detection data distortion, false alarms and missed alarms caused by vibration.

[0044] During the continuous heating and expansion of the airbag 301, the internal air pressure increases in real time. When the air pressure exceeds the preset operating threshold of the pressure relief valve 403, the adjustable pressure relief valve 403 automatically opens to release pressure. The high-pressure gas inside the airbag 301 is introduced into the cavity of the mounting box 101. Utilizing the principle of hot air rising, the high-pressure hot gas is discharged from the top heat exhaust groove 401, while the low-temperature outside air is continuously replenished from the bottom air inlet groove 402, forming a stable convection heat dissipation channel. This simultaneously removes the heat generated by the detector 110 and the redundant heat from the heating mechanism 200, preventing the internal heat accumulation from damaging the electronic components. After the pressure is released, the pressure relief valve 403 automatically closes, and the airbag 301 maintains a constant air pressure and expansion state, continuously maintaining the reinforcement and shock absorption effect on the detector 110. If the airbag 301 is slightly under-pressurized due to long-term static storage, the one-way air inlet valve 303 can automatically replenish air to ensure that the airbag 301 is always in an effective working state.

[0045] Through the integrated linkage design of heating for defogging and de-icing, residual heat airbag 301 adaptive reinforcement, and overpressure convection heat dissipation, there is no need for multiple independent control structures. It can adapt to various complex outdoor working conditions such as high temperature, low temperature, rain, snow, strong wind, and icing, ensuring that the detector 110 works stably and accurately around the clock, and greatly reducing the equipment failure rate and maintenance costs.

[0046] In summary, during the testing process using the testing mechanism 100, the heating mechanism 200 first melts the ice on the surface of the testing end and prevents water vapor condensation from affecting the imaging. When the heating mechanism 200 is in use, the shock-absorbing mechanism 300 is activated simultaneously to expand, which can effectively buffer the vibration caused by strong winds and avoid affecting the testing effect of the testing mechanism 100. At the same time, when the internal air pressure of the shock-absorbing mechanism 300 is too high, it can be discharged through the heat dissipation mechanism 400 and promote the circulation and cooling of the surrounding air of the testing mechanism 100.
