Description

Technical Field

[0001] This utility model relates to the field of de-icing technology, specifically to a de-icing device for power transmission towers. Background Technology

[0002] In recent years, Qingyuan has experienced frequent cold waves, causing severe damage to power transmission lines. From December 16 to 25, 2023, a strong cold wave lasting 10 days led to an average temperature drop of over 14°C across the city, with the lowest temperature at Jinzishan Station in Lianshan reaching -8.5°C, severely impacting industrial and agricultural production and residents' lives. From January 20 to 24, 2024, the average daily temperature dropped by 10-14°C, reaching as low as -5°C in high-altitude mountainous areas, accompanied by freezing rain, sleet, and gusty winds, damaging some power lines. From December 15 to 25 of the same year, temperatures plummeted by 15-17°C, with freezing rain and ice formations in the northern high-altitude mountainous areas. Severe icing occurred on power lines in areas such as Tanling, damaging crossarms, poles, and other facilities. According to the "Southern Power Grid Ice Zone Distribution Map (2024 Edition)," the ice thickness in some high-altitude areas of Qingyuan has reached up to 30mm. The 220kV power transmission towers in mountainous areas are the core structure of the power grid, making de-icing of these towers a key task during cold waves. Inspired by existing technologies, power grid workers have previously installed resonant devices at the base of power towers to address icing. However, in practical applications, the resonance effect of these devices, transmitting upwards from the base of the tower, is not very effective, resulting in minimal ice removal. Furthermore, the resonant devices are easily damaged by the low temperatures and humidity in mountainous areas, requiring frequent maintenance and replacement. Clearly, this approach is unsuitable for de-icing power towers, necessitating the exploration of a new and reliable de-icing method. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a power tower de-icing device, which uses a drone to carry a modified sound wave generator to carry out de-icing operations on power towers, and the de-icing effect is obvious.

[0004] The technical solution of this utility model is as follows: a power tower de-icing device, comprising a drone, a protective frame, a sound wave generator, a battery assembly, and a control assembly. The sound wave generator and the battery assembly are fixedly connected to the lower end of the drone, one in front and one behind. The sound wave generator and the battery assembly are fixedly connected by the protective frame, which covers the outside of the sound wave generator and the battery assembly. The control assembly is fixedly connected to the protective frame between the sound wave generator and the battery assembly. The front end of the drone is equipped with a camera that can rotate up and down. The output end of the sound wave generator is a vibration head, which is fixedly connected to the upper end of the sound wave generator by a bracket. The vibration head extends forward and protrudes from the device. The battery assembly is electrically connected to the drone, the camera, the sound wave generator, and the control assembly respectively. The control assembly is connected to the drone, the camera, and the sound wave generator respectively via signal. The control assembly is equipped with a communication module.

[0005] Furthermore, the front end of the sound wave generator is equipped with an LED light, which is electrically connected to the battery assembly and connected to the control assembly via a signal.

[0006] Furthermore, the drone containing the camera has a baffle on its upper part, with the front end of the baffle extending beyond the camera.

[0009] Furthermore, the airport has two symmetrically hinged outer shells on both sides, and an opening and closing mechanism is provided inside the airport. The two outer shells can be opened or closed through the opening and closing mechanism.

[0010] Furthermore, the airport is equipped with temperature and humidity sensors and air conditioning components. When the two shells enclose the airport, they can form a sealed cavity. The upper end of the airport is equipped with a ventilation opening, and the temperature and humidity sensors and air conditioning components are connected to the cavity through the ventilation opening.

[0011] Furthermore, the airport is provided with a protruding landing platform at the top, with a groove in the middle of the landing platform. The sides of the groove are sloping, and the wireless charging area is located in the middle of the groove. At the bottom of the sloping side, there is a drainage channel that slopes downward and connects to the outer wall of the landing platform.

[0012] Furthermore, each outer corner of the protective frame is provided with a guide wheel, and each inner corner of the groove is provided with a guide groove, allowing the guide wheels to rise and fall within the guide groove.

[0013] Furthermore, the inclined surface is provided with ribs, the upper end of the ribs is flush with the upper end of the landing platform, and the side of the ribs extends in an arc shape to the bottom of the groove.

[0014] Compared with the prior art, the advantages of this utility model are as follows: When the device is used to de-ice power towers, the drone flies to the vicinity of the power tower, starts the sound wave generator and makes the vibrating head vibrate at a certain frequency.

[0022] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0023] like Figure 1-5As shown, a power tower de-icing device includes a drone 6, a protective frame 15, a sound wave generator 12, a battery assembly 10, and a control assembly 11. The sound wave generator 12 and the battery assembly 10 are fixedly connected to the lower end of the drone 6, one in front of the other. The sound wave generator 12 and the battery assembly 10 are fixedly connected by the protective frame 15, which covers the sound wave generator 12 and the battery assembly 10, providing impact protection for the device. The control assembly 11 is fixedly connected to the protective frame 15 between the sound wave generator 12 and the battery assembly 10. The drone 6 has a camera 7 that can rotate up and down at its front end, allowing real-time monitoring of the situation in front of the drone 6. The output end of the sound wave generator 12 is a vibrating head. 14. The vibrating head 14 is fixedly connected to the upper end of the sound wave generator 12 via the bracket 13. The vibrating head 14 extends forward and protrudes from the device, and can come into contact with the ice layer of the power tower. The vibrating head 14 can adopt a knife-shaped structure. The vibrating head 14 has a ceramic insulation layer inside, which are all conventional technical means that can effectively avoid the impact of the power tower. The battery component 10 is electrically connected to the drone 6, camera 7, sound wave generator 12 and control component 11 respectively. The control component 11 is connected to the drone 6, camera 7 and sound wave generator 12 via signal. The control component 11 has a communication module. The power grid control console can operate the drone 6, camera 7 and sound wave generator 12 through the communication module. In terms of the hardware used in this device, the drone 6 is a DJI industrial-grade quadcopter drone 6, which can carry an additional 8KG of weight. All four rotors are surrounded by the frame, effectively preventing rotor damage and crashes caused by accidental contact with power lines during operation. The sound wave generator 12, based on the principle of the Quen resonance de-icing device, uses a Shengdao Xinghe megaphone, weighing approximately 2KG. It replaces the loudspeaker with a low-frequency transducer, capable of generating sound waves with a sound pressure level of 115dB and a frequency of 50-500Hz, matching the ice layer's breaking resonance frequency range of 20-200Hz, with a maximum ice-breaking thickness of 100mm, without damaging the metal structure of the power tower. The battery assembly 10 is assembled from multiple battery modules, weighing approximately 2KG. The sound wave generator 12 has a relatively uniform weight, providing balance for the device. The control component 11 is located between the sound wave generator 12 and the battery component 10, ensuring that the center of gravity of the device is in the center, avoiding instability of the drone 6 due to uneven weight distribution. The overall weight of the control component 11 and the protective frame 15 does not exceed 1KG, and the overall load of the drone 6 does not exceed 5KG, which is within a safe range. When the device is used to de-ice power towers, the drone 6 flies to the vicinity of the power tower, activates the sound wave generator 12, and enables the vibrating head 14 to generate a certain frequency of vibration. Under the real-time transmission of the camera 7, the power grid control console controls the drone 6 to fly close to the power tower, and the vibrating head 14 comes into contact with the ice layer, causing the ice layer to resonate and break.

[0024] In the above embodiment, the front end of the sound wave generator 12 is equipped with an LED light 1201, which is electrically connected to the battery assembly 10 and signal-connected to the control assembly 11. During periods of low nighttime temperatures, icing of power towers is frequent. The LED light 1201 can be used by this device for nighttime de-icing operations, ensuring that the icing of power towers can be dealt with in a timely and effective manner. The upper end of the drone 6, where the camera 7 is located, is equipped with a baffle 8. The front end of the baffle 8 extends beyond the camera 7. When this device is performing de-icing operations, ice chips may fall from the top of the power tower. The baffle 8 can effectively shield the camera 7, preventing damage to the camera 7 and thus preventing the device from losing real-time images. The sound wave generator 12 and the battery assembly 10 are both fixedly connected to the lower end of the drone 6 by a hanging ring 9. The hanging ring 9 is long and narrow, and the inner side of the hanging ring 9 is covered with a shock-absorbing pad, which can filter the vibration generated by the vibrating head 14, preventing the drone 6 from being disturbed by vibration and causing damage to its internal components or premature loss of flight stability.

[0025] This device also includes an airport 1, with a wireless charging area 402 at its upper end. A transmitting module is located within the wireless charging area 402, and a receiving module is located within the control component 11. The receiving module is electrically connected to the battery component 10. The drone 6 can land on the airport 1, and the control component 11 can approach the wireless charging area 402. The transmitting module can charge the battery component 10 through the receiving module. The transmitting module includes hardware such as a power adapter, microcontroller chip, inverter drive circuit, communication demodulation circuit, planar coil, and high-frequency capacitor, all of which are existing technologies. The receiving module also includes hardware such as a planar coil, high-frequency capacitor, rectifier bridge, filter capacitor, receiving chip, voltage regulator, or converter, all of which are also existing technologies. Two shells 3 are symmetrically hinged on both sides of the airport 1. An opening and closing mechanism 2 is located inside the airport 1. The opening and closing mechanism 2 is conventional existing technology. The two shells 3 can open or close the airport 1 through the opening and closing mechanism 2. When open, the drone 6 can take off and land; when closed, it can prevent sun and rain exposure, avoiding rapid aging of the equipment. Especially in rainy weather, the two shells 3 can effectively prevent rainwater from entering the wireless charging area 402, ensuring charging safety. Airport 1 is equipped with a temperature and humidity sensor and an air conditioning unit. When the two outer shells 3 close Airport 1, a sealed cavity is formed. A vent 101 is located at the top of Airport 1, through which the temperature and humidity sensor and air conditioning unit communicate with the cavity. The air conditioning unit is a conventional, existing technology that provides drying and insulation for the sealed cavity. After the drone 6 lands on Airport 1 and the two outer shells 3 close, the drying and heating functions of the air conditioning unit ensure that there is no moisture at the top of the wireless charging area 402, which could affect charging safety. It also provides insulation for the battery assembly 10, preventing damage from prolonged exposure to the low temperatures of the mountainous environment. In areas with frequent cold and humid weather, if the temperature and humidity sensor detects excessively low temperatures or excessively high humidity, the air conditioning unit can be automatically activated via a pre-set program to create a dry and warm environment for the sealed cavity.

[0026] The airport 1 has a raised landing platform 4 at its upper end. The landing platform 4 has a groove 401 in the middle. The side of the groove 401 is a slope 404. The wireless charging area 402 is located in the middle of the groove 401. The bottom of the slope 404 has a downward-sloping drainage ditch 403 that connects to the outer wall of the landing platform 4. The groove 401 can provide landing space for the drone 6. The drainage ditch 403 can drain water from the wireless charging area 402, preventing rainwater from accumulating in the groove 401 during heavy rain and providing favorable conditions for drying the air conditioning components. At the same time, when the drone 6 takes off and lands, the drainage ditch 403 can also serve as a ventilation channel, effectively avoiding airflow turbulence and helping to improve the stability of the drone 6 during takeoff and landing. The outer corners of the protective frame 15 are equipped with guide wheels 16, and the inner corners of the groove 401 are equipped with guide grooves 405. The guide wheels 16 can be raised and lowered in the guide grooves 405. When the drone 6 lands, with the assistance of GPS positioning and camera 7, the drone 6 may still deviate from the area of ​​the groove 401 or the wireless charging area 402. When the drone 6 lands, the guide wheels 16 can roll along the inclined surface 404, which plays a corrective role during the slow descent of the drone 6, gradually correcting the drone 6 to the center of the groove 401, ensuring that the drone 6 lands smoothly. After the drone 6 finally lands on the upper part of the wireless charging area 402, the heightening effect of the guide wheels 16 creates a certain gap between the control component 11 and the wireless charging area 402, providing favorable conditions for the air conditioning component to dry. The wireless charging function will be activated only after a certain period of drying. Ribs 5 are provided on the inclined surface 404. The upper end face of the ribs 5 is flush with the upper end face of the landing platform 4. The side of the ribs 5 extends in an arc shape to the bottom of the groove 401. The ribs 5 can provide guidance for the outer frame 15 of the sound wave generator 12 and the battery assembly 10, so that the frame 15 can slide down along the ribs 5, further improving the stability of the UAV 6 when landing.

[0027] Description of the working principle of this utility model:

[0028] This device is installed at a communication base station in a mountainous area, using the base station's power to supply power to the device's airport 1. Simultaneously, the base station provides good communication conditions, ensuring the flight signal safety of the drone 6. In mountainous areas encountering cold weather or when the weather station issues an icing warning, the power grid system can determine the degree of power transmission efficiency loss between power towers. When power towers are severely iced, the transmission loss can reach up to 20%. When the transmission loss exceeds 2%, the outer shell 3 on both sides of airport 1 is opened via the power grid control console, and the drone 6 is launched for inspection. After the drone 6 arrives at the power tower, the real-time video transmitted by the camera 7 shows whether the power tower is iced. If obvious icing is found, the sound wave generator 12 can be remotely activated, controlling the drone 6 to slowly approach the power tower. The vibrating head 14 then contacts the ice layer, causing the ice to resonate and break apart, achieving... De-icing effect: During de-icing operations, the work should be carried out from top to bottom on the outside of the power tower to avoid ice debris falling from above the work area and hitting the drone. Since the power tower has a trapezoidal structure, the ice layer on the inside of the tower is more easily removed during resonant de-icing on the outside. Field investigations show that this device can remove nearly 80% of the ice on the outside of the power tower and up to 65% on the inside. Calculations show that under severe icing conditions on power towers, the power grid transmission efficiency can be restored from 82% to 93.5%, saving a significant amount of electrical energy and ensuring grid safety.

[0029] It should be noted that during the inspection and de-icing operation of the UAV 6, if the battery pack 10's power drops to the warning line, the sound wave generator 12 will immediately stop operating, and the UAV 6 will automatically return to base, ensuring that the UAV 6 has enough range to return to airport 1 and guaranteeing the safe use of this device.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
