Description

Technical Field

[0001] This invention relates to the field of power equipment maintenance technology, specifically to a remote-controlled handheld high-power snow blowing and snow removal device for substation operating insulators. Background Technology

[0002] In the field of power system operation and maintenance, 110kV substation insulators are the core equipment to ensure the electrical insulation and mechanical support of transmission and transformation lines. Winter snow accumulation can lead to a decrease in their insulation performance, an increase in mechanical load, and even flashover accidents. Therefore, snow removal from insulators is a key task for substation operation and maintenance in winter.

[0003] Currently, snow removal technology for insulators in 110kV substations in the industry is mainly based on manual operation. Traditional snow removal methods, such as manual removal with insulator poles and manual removal with simple snow scrapers, have problems such as small removal area per operation, low efficiency, high safety risks, and difficulty in controlling snow removal quality. With the development of smart grids, although efforts have been made to optimize snow removal tools, the limitations of traditional operation modes have not yet been broken, and snow removal efficiency and safety urgently need to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a remote-controlled, handheld, high-power snow blowing and snow removal device for substation operating insulators. The snow removal device consists of five major modules: snow blowing execution, real-time monitoring, remote control, power supply, temperature control, and main control. Its practical application results are significant. Compared with traditional snow removal methods, this device greatly improves snow removal efficiency, reducing the average snow removal time by 74.4%. Operational safety is significantly improved; non-contact snow blowing avoids scratches, and remote operation mitigates electrical risks. It has excellent adaptability and portability, is compatible with existing insulator poles, and can be carried by a single person to substations in different terrains, reducing operation and maintenance costs and minimizing manpower and insulator replacement costs.

[0005] The technical problem solved by this invention is:

[0006] (1) Improve snow removal and ice melting efficiency. By optimizing the single clearing range of snow removal tools, the traditional 3cm clearing range is extended to more than 15cm. The integrated temperature controller realizes automatic ice recognition and melting, significantly shortening the snow removal time to less than 20 minutes and improving work efficiency. The integrated real-time monitoring system shortens the observation distance from the traditional 2.5 meters to less than 0.5 meters. Through high-definition cameras and wireless transmission technology, close-range accurate observation is realized to ensure that there is no snow or ice residue and avoid the reduction of insulation performance or flashover accidents caused by residue.

[0007] (2) Enhance operational safety by adopting a non-contact snow blowing design to avoid mechanical damage to the surface of insulators by traditional metal hooks and scrapers. At the same time, it supports remote operation, allowing maintenance personnel to work at a safe distance, reducing the risk of electric shock and high-altitude work hazards in high-voltage environments.

[0008] (3) Improve the applicability of the device by designing a lightweight and modular structure that is compatible with different types of insulators such as support, suspension and bushing, and is compatible with existing insulating rod interfaces. This ensures that the device can operate stably in low-temperature environments from -15℃ to 6℃. At the same time, the battery life problem is solved by a removable lithium battery, which is convenient for maintenance personnel to carry and operate on site.

[0009] The objective of this invention can be achieved through the following technical solutions:

[0016] The main control module is electrically connected to the snow blowing execution module, temperature control ice melting module, real-time monitoring module, remote control module and power supply module. It is used to receive control signals and sensor data, and execute integrated control logic to coordinate the work of each module.

[0017] As a further aspect of the present invention: the temperature controller is an NTC temperature controller, with a preset heating start threshold of ambient temperature ≤ 0℃ and a heating stop threshold of ambient temperature ≥ 5℃;

[0018] The heating wire has a rated power of 50W and is wound and arranged on the inner wall of the conical snow blowing duct in an area 10cm away from the air outlet.

[0019] As a further aspect of the present invention: the main control module adopts an STM32F103 series central control chip, which has a pre-set 3-level wind speed adjustment program.

[0020] The main control module is also pre-set with temperature control linkage logic. When the temperature control ice melting module detects ice accumulation conditions, it automatically controls the DC brushless duct motor to switch to the highest wind speed and controls it to return to the preset wind speed after the ice melting is completed.

[0021] As a further aspect of the present invention: the power supply module includes a lithium polymer battery with a rated voltage of 12V and a capacity of 15Ah, and the lithium polymer battery is connected to the main body of the device using a snap-fit ​​interface;

[0022] The power supply module also includes a 15A overcurrent protection switch, a 12V / 2A charger, and at least two backup batteries.

[0023] As a further aspect of the present invention: the remote control handle integrates a 2.4-inch LCD display screen and is equipped with a start / stop button, a fan speed adjustment button, a mode switching button, and a temperature control status indicator light.

[0024] As a further aspect of the present invention: the temperature control status indicator light is red to indicate that heating is in progress and green to indicate that heating has stopped;

[0025] The remote control module can receive and display real-time images and temperature data transmitted back by the real-time monitoring module, and its effective communication distance is not less than 10 meters.

[0026] As a further aspect of the present invention: the camera in the real-time monitoring module is a 1080P resolution, 120° field of view real-scene camera, and the optical axis of its lens is aligned with the airflow direction of the outlet of the conical snow blowing duct.

[0027] As a further aspect of the present invention: the wireless communication unit is a Bluetooth 5.0 module.

[0028] As a further aspect of the present invention: the detachable connection interface is a threaded interface, used to adapt to an insulating operating rod with a connection length of 3 to 5 meters.

[0030] The beneficial effects of this invention are:

[0031] (1) The device of the present invention can clear an extended range of 17.57cm in a single operation. Combined with three-level wind speed adjustment and automatic temperature control de-icing function, during the test, the average snow removal (including de-icing) time of 110kV substation insulators was reduced to 15.52min, which is 74.4% shorter than the traditional method, greatly improving the snow removal and de-icing efficiency.

[0032] (2) The present invention adopts a non-contact snow blowing design to avoid direct contact between the tool and the insulator, thus eliminating the risk of scratches; the real-time monitoring module shortens the monitoring distance to 0.45m, which is much lower than the traditional 2.5m. Maintenance personnel can operate remotely through the remote control handle without having to get close to the insulator, thus completely avoiding electrical safety risks such as grounding and short circuits; the design of the heating wire ceramic insulation layer and the air duct heat insulation coating prevents the risk of electric shock and burns, significantly improving the safety of operation;

[0033] (3) The present invention uses a real-view camera to transmit images in real time, combined with temperature feedback from the temperature controller, so that maintenance personnel can clearly observe the snow and ice residue, ensuring thorough cleaning. During the test, the snow and ice residue rate of the insulators dropped to below 0.5%, effectively avoiding flashover accidents after snow melting and improving the controllability of snow removal quality.

[0034] (4) The threaded interface at the bottom of the device is compatible with existing 110kV substation insulating rods and is suitable for three types of insulators: post, suspension, and bushing. The device weighs about 2.8kg including the battery. It is equipped with a portable case and a spare battery, and can be carried by a single person to various substation sites. It is suitable for different terrain environments of 32 110kV substations in Shizuishan area, which improves the adaptability and portability of the device. Compared with the traditional manual operation with two people, this device only requires one person to complete snow removal and ice melting, reducing labor costs and reducing the frequency of insulator replacement due to mechanical damage.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1-2 As shown, the present invention is a remote-controlled handheld high-power snow blowing and snow removal device for substation operating insulators, including a snow blowing execution module, a real-time monitoring module, a remote control module, a power supply module, a main control module, and a temperature-controlled ice melting module. The snow blowing execution module, real-time monitoring module, remote control module, power supply module, and temperature-controlled ice melting module are electrically connected to the main control module to receive control signals and sensor data, and execute integrated control logic to coordinate the work of each module.

[0042] The snow blowing actuator module includes a DC brushless ducted motor and a snow blowing duct and air outlet;

[0043] DC brushless ducted motor: The selected model is a high-speed motor suitable for 110kV substation operation. Dimensions are as follows. Figure 3 With a rated power of 300W and a rated speed of 12000r / min, it can generate a strong airflow with a wind speed greater than 10m / s. The motor is fixed in the center of the device housing by bolts, and the motor output shaft is directly connected to the snow blowing duct inlet to ensure lossless airflow transmission.

[0044] Snow blowing duct and outlet: The duct adopts a conical design, with an inlet diameter matching the output end of the DC brushless ducted motor (49mm) and an outlet diameter enlarged to 20cm to achieve airflow diffusion; the outlet edge is rounded to avoid damage to the insulator from sharp structures; a 0.5mm high-temperature resistant epoxy resin heat insulation coating is added to the inner wall of the duct to prevent heat conduction to the device shell; the duct and the device shell are integrally molded, and a threaded interface is set at the bottom of the shell, which can be detachably connected to the commonly used insulating rods in 110kV substations to meet the snow removal needs of insulators of different heights.

[0045] The real-time monitoring module includes a real-view camera and a wireless communication module;

[0046] Real-view camera: A high-definition night vision camera (1080P resolution, 120° field of view) is selected and installed 5cm above the air outlet of the snow blowing duct. The lens is oriented in the same direction as the airflow at the air outlet to ensure that the captured image covers the snow removal area of ​​the insulator. The camera is connected to the STM32 central control chip of the main control module through a ribbon cable to transmit the snow and ice removal images in real time.

[0047] Wireless communication module: It adopts a Bluetooth 5.0 module, which is integrated into the main control module and pairs with the communication module in the remote control handle to transmit the image captured by the camera to the display screen of the remote control handle, so that maintenance personnel can remotely observe the snow removal and ice melting effect.

[0048] The power supply module includes a high-capacity lithium battery, a charger, and a backup battery;

[0049] The high-capacity lithium battery uses a 12V / 15Ah lithium polymer battery, which has the capacity to meet 25 minutes of continuous snow removal. The battery is installed at the rear of the device housing via a snap-on interface, allowing for quick disassembly and replacement. A 15A overcurrent protection switch is connected in series between the battery and the main control module to prevent short circuits from damaging components.

[0050] Charger and spare battery: The charger outputs 12V / 2A and takes 1.5 hours to fully charge one battery; the spare battery has the same specifications as the main battery and comes with two batteries to ensure long-term operation; the charger and spare battery are stored in a dedicated portable case for easy carrying by maintenance personnel.

[0051] The main control module includes an STM32 central control chip and a power display unit;

[0052] The STM32 central control chip, model STM32F103, integrates data processing, motor control, camera signal conversion, and temperature control logic processing functions. The chip connects via wires to a DC brushless ducted motor (controlling speed and start / stop), a real-view camera (receiving image signals), a wireless communication module (transmitting images and control commands), a power display unit (displaying real-time battery charge), and a temperature-controlled ice-melting module (controlling the heating element's on / off state). The chip's program has three preset fan speeds: low (6 m / s), medium (10 m / s), and high (14 m / s) to adapt to different snow thicknesses. It also incorporates temperature control linkage logic, automatically switching to the high fan speed when ice is detected and reverting to the medium speed after ice melting is complete.

[0053] Battery power display unit: It adopts an LED digital tube display screen, which is installed on the side of the device casing and connected to the STM32 central control chip through wires. It displays the remaining battery power in real time. When the power is lower than 10%, it will automatically flash an alarm to remind you to replace the spare battery.

[0054] The remote control module includes a remote control handle and a command transmission mechanism;

[0055] Remote control handle: Dimensions 15cm×8cm×5cm, weight approximately 200g, easy to operate with one hand. The front of the handle features a 2.4-inch LCD screen that can receive and display live camera footage and real-time temperature. Four buttons are located on the side: "Start / Stop" (controls motor start / stop), "Fan Speed ​​+" (increases fan speed), "Fan Speed ​​-" (decreases fan speed), and "Mode Switch" (switch between automatic and manual temperature control modes; manual mode is for emergency use only). The handle has a built-in rechargeable lithium battery with an 8-hour battery life. A "Temperature Control Mode Indicator" is located on the front; red indicates heating is in progress, and green indicates heating is stopped.

[0056] Command transmission mechanism: The remote control handle is paired with the wireless communication module of the main control module via Bluetooth. After the button is pressed, the command is transmitted to the STM32 central control chip in the form of digital signal. After the chip analyzes the command, it controls the DC brushless ducted motor to adjust the speed or the working status of the temperature control ice melting module. At the same time, the camera image and temperature data are transmitted back to the handle display screen to realize the "operation-observation-feedback" closed loop.

[0057] The temperature-controlled ice-melting module includes a temperature controller and a heating wire assembly;

[0058] The temperature controller uses an NTC thermistor, model DS18B20, with a measurement range of -55℃ to 125℃ and an accuracy of ±0.5℃. The temperature sensor probe is installed 5cm inside the air outlet of the snow blowing duct to detect the surface temperature feedback of the insulator in real time (the temperature signal reflected after the airflow contacts the insulator). It is connected to the STM32 central control chip via a wire. The preset ice melting trigger threshold is as follows: when the detected temperature is ≤0℃, it is determined that ice accumulation exists and the heating function is triggered; when the temperature is ≥5℃, it is determined that the ice accumulation has melted and the heating is stopped.

[0059] The heating wire assembly uses a 50W nickel-chromium alloy heating wire, which is spirally wound around the inner wall of the snow blowing duct in an area 10cm from the air outlet. The two ends of the heating wire are connected to the power output of the main control module through high-temperature resistant wires, and the STM32 central control chip controls the on and off according to the temperature controller signal. The heating wire is wrapped with a ceramic insulation layer to avoid short circuit with the metal material of the air duct, and to prevent the heating wire from overheating and damaging the air duct.

[0060] In a specific embodiment:

[0061] Installing a DC brushless ducted motor: A specific size has been selected, such as... Figure 2 The DC brushless ducted motor shown has the characteristics of high speed and large air volume, which is the key to generating strong wind to blow away snow. The motor is firmly installed in the predetermined air duct start end inside the device housing to ensure that it is precisely connected with the subsequent conical snow blowing air duct, thus forming the power core of the snow blowing execution module.

[0062] Installing the STM32 central control chip: The STM32F103 series chip is used as the core of the main control module. The central control chip is soldered to the corresponding position on the custom-designed PCB circuit board. Then, through programming and debugging, the control program is written into the chip. The program integrates the adjustment logic of 3 wind speeds (6m / s, 10m / s, 14m / s), temperature control linkage logic, and subsequent fault self-diagnosis function, realizing intelligent management and data calculation and analysis of all functions of the device.

[0063] Installing a lithium battery: A power supply module was installed on the completed PCB circuit board. This module is based on a lithium polymer battery with a rated voltage of 12V and a capacity of 15Ah. It is connected to the circuit board through a snap-on interface and provides stable power to the entire device. This design ensures the portability of the device and meets the battery life requirements for continuous operation.

[0064] Housing Design: The housing was designed to integrate all electronic modules and mechanical components, taking into account their dimensions and layout. The design fully considers heat dissipation, insulation safety, and ergonomics for handheld operation. All installed modules, including the snow-blowing module, main control module, and power supply module, are assembled within the housing according to their designed positions, forming a complete integrated handheld device. A standard threaded interface is provided at the bottom of the device.

[0065] Single-shot snow removal range test verification: To verify the snow-blowing performance of the device, a test was conducted, the test method as follows: Figure 4 As shown: Place the anemometer 0.5 meters directly in front of the air outlet of the snow blowing device and move it horizontally. Measure the coverage area where the wind speed is continuously greater than 10 m / s. This area is the effective clearing range of the device in a single operation.

[0066] Test results confirmed that at this distance, the device can generate and maintain sufficient wind force to effectively clear snow from the covered area, providing key operating parameters for on-site operations.

[0067] Further: Design for real-time monitoring systems:

[0068] Install a real-view camera: Install a 1080P resolution, 120° field of view real-view camera module in the corresponding position on the front PCB board of the device. During installation, precisely calibrate the optical axis of the lens to ensure that its orientation is strictly consistent with the airflow direction of the conical snow blowing duct outlet, so as to ensure that the image seen by the operator on the remote control screen is the target area affected by the airflow;

[0069] Installation and debugging of the communication module: The Bluetooth 5.0 module is selected as the wireless communication unit and integrated with the camera onto the PCB board. By debugging the communication module, a stable and low-latency data connection can be established between it and the remote control, which is used to transmit high-definition video images and status data such as temperature.

[0070] Monitoring Distance Verification: Considering the safety requirements of live insulator operation in substations, a safety distance of no less than 0.3 meters was determined between the device and the live insulator. Furthermore, based on the aforementioned wind speed test results, the device maintains excellent snow-blowing performance while meeting the safety distance requirement at a distance of 0.5 meters. Therefore, the effective observation and operation distance of the real-time monitoring system was set to 0.3 to 0.5 meters. Within this distance range (especially at a close distance of 0.45 meters), the camera can provide clear observation images, assisting operators in performing precise and safe remote control operations.

[0071] The core of this invention lies in the collaborative design of snow blowing and temperature-controlled ice melting: a 49mm diameter DC brushless ducted motor and a 20cm conical air outlet generate a strong airflow of ≥10m / s. Combined with a temperature controller and a 50W nickel-chromium alloy heating wire, it achieves a single-pass clearing range of 17.57cm while automatically completing a closed-loop control of "heating and melting ice at ≤0℃ and stopping heating at ≥5℃", solving the problems of small range and lack of ice melting ability of traditional tools.

[0072] Multi-module linkage control technology: The STM32F103 central control chip integrates motor speed regulation, camera signal processing, Bluetooth 5.0 wireless communication, power monitoring and temperature control logic functions to realize the linkage of "wind speed switching - image transmission - temperature feedback - power warning" and improve the intelligence level of the device;

[0073] Integrated safety protection design: The inner wall of the air duct has a 0.5mm high-temperature resistant epoxy resin heat insulation coating + heating wire ceramic insulation layer to prevent heat conduction and electrical short circuits; a 15A overcurrent protection switch ensures power supply safety, and together with contactless operation and remote control, it comprehensively avoids equipment damage and personnel safety risks.

[0074] Compatibility and battery life optimization: The threaded interface at the bottom of the device is compatible with existing 3-5m insulating poles and is compatible with three types of insulators: post, suspension, and bushing; the design of 12V / 15Ah snap-on lithium battery + 2 spare batteries can meet the requirement of 25 minutes of snow removal and ice melting on a single charge, solving the battery life anxiety of outdoor operations;

[0075] Close-range monitoring and feedback mechanism: 1080P real-view camera + Bluetooth 5.0 transmission enables close-range observation at 0.45m. Combined with temperature display and indicator light feedback on the remote control handle, it ensures that the quality of snow and ice removal is controllable.

[0076] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
