Description

Technical Field

[0001] This invention belongs to the technical field of snow removal equipment for substations, and specifically relates to a snow removal device for high-voltage substations. Background Technology

[0002] When it snows in a substation, snow will accumulate on the main transformer bushings and insulators of low-voltage reactive power equipment. If not cleared in time, this can easily form icicles, causing equipment discharge, tripping, and other accidents. This is especially true in the 110kV reactor bay area of ​​ultra-high voltage substations. If not cleaned promptly, the automatic switching on and off of AVC (Automatic Voltage and Reactive Power Control) can cause the snow to melt and then freeze again, easily forming icicles, causing creepage and seriously affecting the safety of the power grid and equipment.

[0003] In existing technologies, high-voltage substation maintenance personnel use traditional snow removal methods, manually clearing snow by lifting snowplows. This method requires maintenance personnel to hold and swing the snowplows for extended periods, and also necessitates walking back and forth, resulting in high workload, time, and labor costs. The cleared snow falls directly onto the insulator bases or equipment terminals on the substation ground, causing snow accumulation around the equipment and creating a secondary cleaning burden. Furthermore, the cleared snow falling from heights can also land on maintenance personnel, posing a safety hazard and making the method impractical. Summary of the Invention

[0022] Please refer to the following: Figures 1 to 5This invention provides a snow removal device for high-voltage substations. The snow removal device includes a movable support mechanism 10, an adjusting unit 20, a telescopic structure 30, a snow sweeping unit 40, and a guiding mechanism 70. The movable support mechanism 10 has a walking section at its bottom and a horizontally arranged mounting section 15 at its top. One end of the adjusting unit 20 is hinged to the mounting section 15, and the adjusting unit 20 has an extendable adjusting end. One end of the telescopic structure 30 is hinged to the mounting section 15, and the other end is hinged to the adjusting unit 20, for adjusting the tilt angle of the adjusting unit 20. The snow sweeping unit 40 is disposed on the adjusting end and has multiple sweeping positions that can surround insulators. The snow sweeping unit 40 is used to sweep snow through the multiple sweeping positions. The guiding mechanism 70 is disposed on the movable support mechanism 10 and located below the snow sweeping unit 40, for guiding the snow swept down by the snow sweeping unit 40 to the ground.

[0023] In this embodiment, the movable support mechanism 10 has a walking section at the bottom and a horizontally arranged mounting section 15 at the top. One end of the adjustment unit 20 is hinged to the mounting section 15, and the adjustment unit 20 has an extendable adjustment end. One end of the telescopic structure 30 is hinged to the mounting section 15, and the other end is hinged to the adjustment unit 20, used to adjust the tilt angle of the adjustment unit 20. Specifically, the hinge end 14 of the adjustment unit 20 and the mounting section 15 and the hinge end 14 of the telescopic structure 30 and the mounting section 15 are spaced apart. A snow-sweeping unit 40 is disposed on the adjustment end, and the snow-sweeping unit 40 has multiple sweeping positions, each of which can surround the insulator to sweep away the snow accumulated on the insulator. A guide mechanism 70 is disposed on the movable support mechanism 10 and located below the snow-sweeping unit 40, thereby guiding the snow swept down by the snow-sweeping unit 40 to the ground.

[0024] This invention provides a snow removal device for high-voltage substations. Compared with existing technologies, the mobile support mechanism 10 has a horizontally arranged mounting part 15, and an adjustment unit 20 is hinged to the mounting part 15. The adjustment unit 20 has an extendable adjustment end. A snow sweeping unit 40 is disposed on the adjustment end, so the position of the snow sweeping unit 40 can be adjusted by the adjustment unit 20. The bottom of the mobile support mechanism 10 has a walking part, so that the adjustment unit 20 and the snow sweeping unit 40 can be moved by the mobile support mechanism. One end of the telescopic structure 30 is hinged to the mounting part 15, and the other end is hinged to the adjustment unit 20, so that the tilt angle of the adjustment unit 20 can be adjusted by the telescopic structure 30. The adjustment unit 20 moves the snow sweeping unit 40 together, thereby realizing the removal of snow at different heights, avoiding maintenance personnel from holding the pole for a long time to sweep snow, reducing labor intensity, and saving time and effort. The guiding mechanism 70 is mounted on the mobile support mechanism 10 and located below the snow sweeping unit 40. The guiding mechanism 70 guides the snow swept by the snow sweeping unit 40 to the ground, preventing snow from falling directly onto the insulator bases or equipment terminals on the substation ground. This prevents the melting snow from forming a mixture of ice and water that could intrude into equipment gaps, causing short circuits, creepage, and other safety hazards. It also avoids the secondary cleaning burden caused by snow accumulation around the equipment. The mobile support mechanism 10 has a walking section at its bottom, allowing it to move the adjusting unit 20, the telescopic structure 30, and the snow sweeping unit 40 to clear snow from different areas. This reduces the need for maintenance personnel to walk back and forth, lowers workload, improves efficiency, and enhances practicality.

[0025] In some embodiments, please refer to Figures 1 to 3 The adjustment unit 20 includes a transmission belt structure and an adjustment tube 24. One end of the transmission belt structure is hinged to the mounting part 15, and the other end is hinged to the telescopic structure 30. The transmission belt structure has a linear conveying part. The adjustment tube 24 is arranged in the same direction as the linear conveying part, with one end fixedly connected to the linear conveying part and the other end serving as the adjustment end. In this embodiment, one end of the transmission belt structure is hinged to the mounting part 15, and the other end is hinged to the telescopic structure 30, thereby adjusting the tilt angle of the transmission belt structure through the telescopic structure 30. The transmission belt structure has a linear conveying part, and the adjustment tube 24 is arranged in the same direction as the linear conveying part, with one end fixedly connected to the linear conveying part and the other end serving as the adjustment end, thereby adjusting the position of the adjustment tube 24 through the linear conveying part, i.e., the adjustment end moves with the linear conveying part to adjust its position.

[0026] In some embodiments, please refer to Figures 1 to 3The transmission belt structure includes a mounting beam 21, first rollers 22, a conveyor belt 23, and a first drive motor 25. The mounting beam 21 is arranged along the extension direction of the linear conveying section, with one end hinged to the mounting part 15 and the other end hinged to the telescopic structure 30. Two first rollers 22 are provided, rotatably mounted at both ends of the mounting beam 21. The conveyor belt 23 is fitted onto the mounting beam 21 and the two first rollers 22. The conveyor belt 23 constitutes the linear conveying section. The first drive motor 25 is poweredly connected to the first roller 22 closest to the mounting part 15. In this embodiment, the mounting beam 21 is arranged along the extension direction of the linear conveying section, with one end hinged to the mounting part 15 and the other end hinged to the telescopic structure 30, thereby adjusting the tilt angle of the mounting beam 21 via the telescopic structure 30. First rollers 22 are rotatably mounted at both ends of the mounting beam 21, and the conveyor belt 23 is fitted onto the mounting beam 21 and the two first rollers 22. Specifically, the diameter of the first roller 22 is greater than the thickness of the mounting beam 21. The first drive motor 25 is poweredly connected to one of the first rollers 22, so that the first drive motor 25 drives the first roller 22 to rotate, the first roller 22 drives the conveyor belt 23 to rotate, and the conveyor belt 23 can move the adjusting tube 24 to adjust the position of the snow sweeping unit 40.

[0027] In some embodiments, please refer to Figure 3 The regulating pipe 24 is connected to the conveyor belt 23 via a fixing seat 26, and at least one fixing seat 26 is provided. In this embodiment, at least one fixing seat 26 is provided, and each fixing seat 26 is fixedly connected to the conveyor belt 23 and fixedly connected to one end of the regulating pipe 24 near the mounting part 15, so that the regulating pipe 24 is fixedly connected to the conveyor belt 23 via the fixing seat 26, so that the conveyor belt 23 can drive the regulating pipe 24 to move.

[0028] Furthermore, the telescopic structure 30 is a multi-stage hydraulic telescopic rod equipped with a pressure feedback device, improving the adjustment accuracy to ±1cm. The hydraulic system adopts an explosion-proof design to adapt to the high-risk environment of substations.

[0029] In some embodiments, please refer to Figure 1The snow removal device for a high-voltage substation provided in this embodiment of the invention further includes a snow blowing unit 50, which includes a blower 51 and an air outlet 52. The blower 51 is mounted on a movable support mechanism 10, and its outlet is connected to a regulating pipe 24. The air outlet 52 is connected to the extended end of the regulating pipe 24 and is correspondingly arranged with the snow sweeping unit 40. The air outlet 52 is used to blow snow before the snow sweeping unit 40 operates. In this embodiment, the blower 51 is mounted on the movable support mechanism 10, and its outlet is connected to the regulating pipe 24, thereby blowing air into the regulating pipe 24 through the blower 51. The air outlet 52 is connected to the extended end of the regulating pipe 24, and the air outlet 52 directs the air from the regulating pipe 24 for snow blowing. During snow removal, when the snow accumulation is thick, the snow blowing unit 50 blows the snow first, and then the snow sweeping unit 40 sweeps the snow, ensuring effective snow removal.

[0030] Specifically, the air outlet of the air outlet 52 is elongated to increase the area for blowing snow.

[0031] Furthermore, the snow blowing unit 50 also includes multiple heating tubes, which are evenly arranged in the regulating pipe 24 and located at the end of the regulating pipe 24 near the air outlet 52. The heating tubes heat the air in the regulating pipe 24, thereby using hot air to blow snow and prevent snow from freezing on the insulators of the substation. At the same time, when there are icicles on the insulators, the hot air can also cause the icicles to fall off.

[0032] In some embodiments, please refer to Figures 1 to 3The moving direction of the mobile support mechanism 10 is defined as the first direction, and the horizontal direction perpendicular to the first direction is defined as the second direction. The mobile support mechanism 10 includes a housing 11, a mounting frame 12, a second rotating roller, a track 13, and a second drive motor. The housing 11 has a receiving cavity, and the upper end surface of the housing 11 is the mounting part 15. The mounting part 15 is provided with a hinge end 14. The mounting frame 12 is located at the bottom of the housing 11 and is connected to the housing 11. There are two second rotating rollers, which are spaced apart at the bottom of the housing 11 along the first direction and are rotatably connected to the mounting frame 12. There are two tracks 13, which are both sleeved on the outer periphery of the two second rotating rollers and are spaced apart along the second direction. The second drive motor is located on the mounting frame 12 and is poweredly connected to one of the second rotating rollers. In this embodiment, the upper end surface of the housing 11 is the mounting part 15, and the mounting part 15 is provided with a hinge end 14, thereby connecting the adjustment unit 20 to the hinge end 14. A mounting frame 12 is provided at the bottom of the housing 11, and the mounting frame 12 is connected to the housing 11. Two second rotating rollers are also provided at the bottom of the housing 11, spaced apart along a first direction, and rotatably connected to the mounting frame 12. A second drive motor is mounted on the mounting frame 12 and is poweredly connected to one of the second rotating rollers, thereby driving the second rotating roller to rotate. Two tracks 13 are fitted around the outer periphery of the two second rotating rollers, spaced apart along a second direction, connecting the two second rotating rollers, and thus moving the housing 11 through the two second rotating rollers and the two tracks 13. A thick layer of gravel is laid on the ground under the insulated supports of the substation, making it difficult to move using wheels; therefore, tracks 13 are used to improve the stability of movement.

[0033] Specifically, the hinge end 14 is used for hinged mounting beam 21. The second roller, track 13, and second drive motor constitute the walking unit.

[0034] Furthermore, the mounting part 15 is equipped with a rotating platform, the hinge end 14 is set on the rotating platform, and the telescopic structure 30 is hinged to the rotating platform. The rotating platform is rotatably connected to the mounting part. A third drive motor connected to the rotating platform is provided in the housing 11 to drive the rotating platform to rotate. Thus, during the snow sweeping process, the rotating platform can drive the adjustment unit 20, the telescopic structure 30 and the snow sweeping unit 40 to rotate, so as to achieve the cleaning of different parts of the insulator, avoid moving the moving support mechanism 10 back and forth, make the operation convenient and improve work efficiency.

[0035] In some embodiments, please refer to Figure 5The guiding mechanism 70 includes a first connecting rod 71, a second connecting rod 72, a guide housing 73, a first conduit 74, a second conduit 75, and a mounting plate 76. One end of the first connecting rod 71 is hinged to the adjusting pipe 24, and the other end is hinged to one end of the second connecting rod 72. The other end of the second connecting rod 72 is connected to the guide housing 73. The guide housing 73 has a conical guide groove. The opening of the conical guide groove near the snow sweeping unit 40 is the first guide opening, and the opening of the conical guide groove away from the snow sweeping unit 40 is the second guide opening. The diameter of the first guide opening is larger than the diameter of the second guide opening. When the snow sweeping unit 40 sweeps the snow on the insulators, the fallen snow will fall into the conical guide groove of the guide housing 73, preventing the snow from falling directly onto the insulator base or equipment terminals on the substation ground. This prevents the snow from melting and forming an ice-water mixture that intrudes into the equipment gaps, causing short circuits, creepage, and other safety hazards. It also avoids the secondary cleaning burden caused by snow accumulation around the equipment. An auxiliary connecting rod 77 is provided at the first guide port, and the other end of the second connecting rod 72 is connected to the auxiliary connecting rod 77. The guide housing 73 is located below the snow sweeping unit 40, and the snow swept by the snow sweeping unit 40 falls into the guide housing 73. The upper end of the first conduit 74 is fixedly connected to the guide housing 73. The first conduit 74 has a first guide channel that communicates with the second guide port, and the first conduit 74 is a flexible tube. The lower end of the second conduit 75 is fixedly connected to the first conduit 74. The second conduit 75 has a second guide channel that communicates with the first guide channel. The guide housing 73 is hinged to the adjusting tube 24 via the first connecting rod 71 and the second connecting rod 72, and the first conduit 74 is also a flexible tube. When the adjusting unit 20 drives the snow sweeping unit 40 to adjust its height and tilt angle, the guide housing 73 can move synchronously with the snow sweeping unit 40, always maintaining its collection position below it. Simultaneously, the flexible first guide tube 74 can flexibly adapt to the displacement and angle changes of the adjusting tube 24, preventing breakage or detachment due to device posture adjustments, ensuring the continuity and stability of the entire guiding process and not affecting the normal operating stroke of the snow removal device. The mounting plate 76 is horizontally set and connected to the housing 11. The second guide tube 75 is fixedly connected to the mounting plate 76 and is set vertically. Specifically, a counterweight is provided at the second guide opening of the guide housing 73 to keep the guide housing 73 in a vertical state. The counterweight at the second guide port of the guide housing 73 can keep the guide housing 73 in a vertical position at all times. Even when the device moves or the adjustment unit 20 tilts, the guide housing 73 can be prevented from flipping or shifting. This ensures that the first guide port is always facing the cleaning area of ​​the snow sweeping unit 40, maximizing the coverage and reliability of snow collection and preventing snow leakage due to the tilt of the guide housing 73.

[0036] Furthermore, when the regulating pipe 24 moves the snow sweeping unit 40 upward, the guide housing 73 moves along with the regulating pipe 24, and the guide housing 73 is always located below the snow sweeping unit 40. At this time, the length of the first conduit 74 is sufficient to connect the guide housing 73 and the second conduit 75.

[0037] This application provides a snow removal device for a high-voltage substation, which further includes a first water pipe, a second water pipe 80, and a nozzle 90. The first water pipe is a flexible pipe and is arranged along the extension direction of the regulating pipe 24. One end of the second water pipe 80 is connected to the side of the first water pipe near the snow removal unit 40, and the other end of the second water pipe 80 extends to a first guide port. The nozzle 90 is located at the extension end of the second water pipe 80. Water is sprayed into the guide housing 73 through the first water pipe, the second water pipe 80, and the nozzle 90 to melt the snow that falls into the guide housing 73 into water, so that it can be discharged through the first conduit 74 and the second conduit 75, avoiding the accumulation of snow in the first conduit 74 and the second conduit 75. The end of the second conduit 75 away from the first conduit is rotatably connected to the regulating pipe. The regulating pipe is arranged at an angle to the second conduit, and the angle between the regulating pipe and the second conduit is an obtuse angle, so that water can be directed to a designated area by rotating the regulating pipe. The second guide port of the guide housing 73 connects to the flexible first conduit 74, which in turn connects to the vertically fixed second conduit 75, forming a complete flow channel. Sweeped snow can be directly transported to a designated area (such as the water / snow storage area next to the housing 11) through this channel. With the matching first and second water pipes 80 and nozzles 90, the snow can be atomized and melted into water before being discharged. This solves the problem of solid snow clogging the conduits and allows for centralized collection or discharge of melted snow water, preventing water from spreading and maintaining the cleanliness and dryness of the substation operating area. Specifically, a water storage tank is installed in the housing 11, and the other end of the first water pipe is located in the water storage tank. A high-pressure jet pump introduces water from the storage tank into the first water pipe. The nozzle 90 is an atomizing nozzle, which sprays water onto the snow in the guide housing 73 to melt it into water. The high-pressure jet pump is electrically connected to the controller. The guiding mechanism 70 works in conjunction with the atomizing nozzle 90, high-pressure jet pump, and other snow-melting components. The atomizing nozzle 90 sprays water onto the snow inside the guiding housing 73, causing it to quickly melt into liquid water. The fluidity of liquid water is far superior to that of solid snow, allowing it to flow smoothly through the guide channel and effectively preventing solid snow from clumping and clogging in the conical groove or conduit. This ensures the long-term stable operation of the guiding mechanism and reduces the additional workload of manually clearing the conduit.

[0038] In some embodiments, please refer to Figure 4The snow removal unit 40 includes a drive structure, a plate 42, and a cleaning structure. The drive structure is fixedly connected to the adjustment end. The plate 42 is poweredly connected to the drive structure. Multiple cleaning structures are provided, each arranged annularly around the central axis of the plate 42. Each cleaning structure represents a cleaning position. In this embodiment, the drive structure is fixedly connected to the adjustment end, and the plate 42 is poweredly connected to the drive structure, thereby driving the plate 42 to rotate. Multiple cleaning structures are provided, each arranged annularly around the central axis of the plate 42, so that the plate 42 drives each cleaning structure to rotate, forming a suitable angle for snow removal.

[0039] In some embodiments, please refer to Figure 4 Each cleaning structure includes a cleaning brush 43 and a pneumatic motor 44. The cleaning brush 43 is rotatably connected to the plate 42. The pneumatic motor 44 is mounted on the plate 42 and is powered by the cleaning brush 43. A pressure sensor is provided between the cleaning brush 43 and the plate 42. In this embodiment, the cleaning brush 43 is rotatably connected to the plate 42, and the pneumatic motor 44 is powered by the cleaning brush 43, thereby driving the cleaning brush 43 to rotate and clean snow. The pneumatic motor 44 can easily control the rotation force, ensuring that the plate 42 is not damaged. The pneumatic motor 44 can prevent the plate 42 from becoming electrified, ensuring safety. If a common motor is used for ground power supply, it is impossible to guarantee safe insulation between the cleaning structure and the high-voltage electrified support; using lithium batteries or other rechargeable batteries is neither safe nor can it guarantee battery life. A pressure sensor is used to monitor the contact pressure between the cleaning brush 43 and the insulator. Based on the contact pressure measured by the pressure sensor, the cleaning angle of the cleaning brush 43 and the distance between the cleaning brush 43 and the insulator can be adjusted in a timely manner to ensure the cleaning effect. Specifically, a matching controller is also provided, which is electrically connected to the pressure sensor, thereby enabling adaptive adjustment of the contact pressure.

[0040] Furthermore, the multi-stage hydraulic telescopic rod is electrically connected to the controller, and a pressure feedback device is provided on the multi-stage hydraulic telescopic rod. The pressure feedback device is electrically connected to the controller, thereby enabling precise adjustment of the tilt angle and telescopic stroke of the adjustment unit.

[0041] Specifically, the snow removal device for a high-voltage substation provided in this application embodiment also includes a high-pressure air pump 60, which is connected to a pneumatic motor 44 and is used to provide power to the pneumatic motor 44.

[0042] In some embodiments, please refer to Figure 4The drive structure includes a geared motor 41, a sensor, and a controller. The geared motor 41 is electrically connected to the plate 42, and the sensor is used to detect the angle of the plate 42. The controller is electrically connected to the geared motor 41 and the sensor. In this embodiment, the sensor detects the angle between the plate 42 and the ground. When the angle of the plate 42 changes, the sensor transmits a signal to the controller, which then controls the working state of the geared motor 41 (start or stop) to ensure that the plate 42 remains perpendicular to the ground.

[0043] In some embodiments, the snow removal unit 40 further includes a camera, which is mounted on the plate to monitor the cleaning progress. The camera is electrically connected to the controller. In this embodiment, the camera is mounted on the plate to monitor the cleaning progress at any time, ensuring that the snow is completely removed and guaranteeing the cleaning effect.

[0044] In some embodiments, the sensor is a six-axis gyroscope. A six-axis gyroscope is a motion sensor that integrates a three-axis gyroscope and a three-axis accelerometer, and can simultaneously measure the angular velocity and linear acceleration of an object. It is widely used in attitude control and motion tracking.

[0045] Specifically, the controller uses a microcontroller (using an STM32F407 chip, which is existing technology). It acquires images via a camera, performs image resolution and display, thereby positioning the sweeping brush 43, determining the sweeping location, and allowing real-time monitoring of the sweeping status, enabling automatic sweeping. It also prevents the sweeping brush 43 from colliding with surrounding equipment, improving safety. Using data measured by a six-axis gyroscope sensor, the board 42 is adjusted to be perpendicular to the ground, thus adjusting the angle of the sweeping brush 43, ensuring that each brush surrounds the insulator for snow sweeping.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
