Abstract
Description
Technical Field
[0001] This utility model relates to the field of power grid de-icing technology, specifically to a power grid de-icing device. Background Technology
[0002] With global climate change, the frequency and intensity of extreme weather events have increased, posing new challenges to the safe operation of power grids. Especially in cold regions, transmission lines are prone to icing under severe weather conditions such as blizzards and freezing rain in winter. This icing not only increases the burden on transmission lines, causing towers to tilt or even collapse, but also causes faults such as phase-to-phase short circuits and flashover tripping, seriously affecting the stability and security of the power system.
[0003] Traditional de-icing methods mainly include mechanical de-icing, thermal de-icing, and natural detachment. Mechanical de-icing primarily involves physical removal of ice through manual knocking or the use of specialized equipment. However, this method is inefficient and highly dangerous, especially at high altitudes and in high-wind environments. Thermal de-icing uses electric heating or spraying anti-icing fluid to melt the ice. While effective, it is energy-intensive and poses certain environmental concerns. Natural detachment, on the other hand, is entirely dependent on weather conditions and is highly unpredictable.
[0004] The patent with publication number CN218850348U discloses a de-icing device for power distribution lines, including a housing, a movable wheel fixedly connected to one end of a rotating shaft, a driven gear fixedly connected to the other end of the rotating shaft, a motor fixedly connected to the bottom end of a cover plate, a drive gear fixedly connected to the drive end of the motor, an ice-breaking blade fixedly connected to one end of a support plate, and sliding blocks threadedly connected to both outer walls of the bidirectional threaded rod, with a de-icing blade fixedly connected to one end of each sliding block.
[0005] However, the above-mentioned device has the following problems when in use: This type of cable de-icing device breaks the ice layer by striking the ice-covered area with de-icing blades. After the ice is broken, it falls directly under the force of gravity, which may cause injury or damage to personnel, equipment, or vehicles passing below. Especially when working at heights, the falling ice may have considerable speed and kinetic energy, increasing the potential risk and posing certain safety hazards, making it unsuitable for use.

A fixed platform is fixedly mounted on the body, and two connecting plates are slidably mounted on the platform. Heating semi-rings are fixedly mounted on each connecting plate. A collection mechanism is provided on the body.
[0009] Preferably, a bidirectional threaded rod is rotatably mounted on the fixed platform. Two threaded pairs are installed on the bidirectional threaded rod by threads.

[0015] This invention integrates various mechanical and thermal components to effectively remove ice buildup on power grids. Its beneficial effects are mainly reflected in the following aspects: First, the combination of a telescopic rod with driving and driven wheels allows the device to adapt to cables of different sizes and heights, improving versatility and operational flexibility.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figures 1 to 4 An ice-removing device for power grids includes a body 1, on which a mounting frame 2 is fixedly installed. The body 1 serves as the basic support structure for the entire ice-removing device. The mounting frame 2 is used to install other components and provides a fixed position for the installation of subsequent equipment. The body 1 can be equipped with structures such as an energy storage box, so that the equipment can operate stably.
[0023] Two drive motors 4 are installed on the fixed frame 2. The output end of the shaft of the drive motor 4 passes through the fixed frame 2 and is fixedly installed with a drive wheel 3. The drive motor 4 provides power to the drive wheel 3. The rotation of the drive wheel 3 can drive the ice removal device to move on the power grid, thereby realizing the position movement of the ice removal operation.
[0024] The body 1 is equipped with two telescopic rods 6. The other end of the telescopic rods 6 is fixedly mounted with a mounting plate 5. Two sets of driven wheels 7 are rotatably mounted on the mounting plate 5. The telescopic rods 6 are adjustable in length, thereby changing the position of the mounting plate 5. This allows them to adapt to different sizes of power grid cables, making the ice-clearing device more versatile. In use, the upper and lower ends of the cable are respectively in contact with the driving wheel 3 and the driven wheel 7. The driven wheel 7 can rotate as the driving wheel 3 moves, assisting the ice-clearing device to move smoothly on the power grid, sharing some of the pressure and ensuring smooth movement.
[0025] A fixed platform 12 is fixedly installed on the body 1. Two connecting plates 13 are slidably installed on the fixed platform 12. A heating half-ring 14 is fixedly installed on each of the two connecting plates 13. The fixed platform 12 provides support and guidance for the sliding of the connecting plates 13. The heating half-ring 14 is used to heat and melt the ice on the cable to achieve the ice removal function.
[0026] The main body 1 is equipped with a collection mechanism, which is used to collect the melted ice water after heating, so as to prevent the ice water from dripping randomly and affecting the environment or equipment below.
[0027] A bidirectional threaded rod 17 is rotatably mounted on the fixed platform 12. Two threaded pairs 18 are threadedly mounted on the bidirectional threaded rod 17. The two threaded pairs 18 are fixedly connected to the corresponding connecting plates 13. The two connecting plates 13 are located in different thread directions of the bidirectional threaded rod 17.
[0028] When the bidirectional threaded rod 17 is rotated, the two connecting plates 13 will move towards or away from each other because they are in different thread directions, thereby adjusting the opening and closing of the two heating half rings 14, making it easier to place the equipment on the cable or remove it from the cable.
[0029] A drive gear 19 is fixedly installed on the bidirectional threaded rod 17, a connecting block 16 is fixedly installed on the mounting plate 5, and a toothed plate 15 is fixedly installed on the connecting block 16. The toothed plate 15 and the drive gear 19 are meshed.
[0030] When the telescopic rod 6 extends or retracts, causing the mounting plate 5 to move, the toothed plate 15 will move accordingly. Through meshing with the drive gear 19, it will drive the bidirectional threaded rod 17 to rotate, thereby automatically adjusting the opening and closing of the two heating half-rings 14, realizing automated operation and facilitating direct operation.
[0031] The two heating half-rings 14 are installed in a staggered manner. The staggered installation of the heating half-rings 14 can more comprehensively heat cables of different diameters, avoid heating dead spots, and improve the use effect.
[0032] The collection mechanism includes a collection box 8, which is fixedly installed on the body 1. A drain pipe 10 is embedded in the collection box 8, and a control valve 11 is provided on the drain pipe 10. The collection box 8 is used to collect melted ice water, and the drain pipe 10 facilitates the discharge of water from the collection box 8. The control valve 11 can control the timing and flow rate of the drainage.
[0033] Both heating half-rings 14 are located directly above the collection box 8, and the inside of the collection box 8 is equipped with a constant temperature plate 9. The ice water that melts directly above the heating half-rings 14 can drip directly into the collection box 8. The constant temperature plate 9 can maintain the water temperature inside the collection box 8 and prevent the water from freezing again and clogging components such as the drain pipe 10. Since the installation of the constant temperature plate 9 and the circuit are existing technologies, they will not be described in detail here.
[0034] The working process of this utility model is as follows: In the initial state, the telescopic rod 6 is in the retracted state, which drives the mounting plate 5 to move. The toothed plate 15, which is fixed to the connecting block 16 on the mounting plate 5, also moves accordingly. Since the toothed plate 15 meshes with the drive gear 19, it will drive the bidirectional threaded rod 17 to rotate. Because the two connecting plates 13 are located in different thread directions of the bidirectional threaded rod 17, the two connecting plates 13 move in opposite directions, so that the two heating half rings 14 open. At this time, the ice-clearing device can be placed on the cable. The cable is located between the drive wheel 3 and the driven wheel 7, and it is necessary to make the cable between the two heating half rings 14.
[0035] Adjusting the extension of the telescopic rod 6 changes the position of the mounting plate 5, making the driven wheel 7 fit tightly with the cable to accommodate different sizes of power grid cables. At the same time, the extension of the telescopic rod 6 drives the mounting plate 5 to move, and the toothed plate 15 moves in the opposite direction. It then drives the bidirectional threaded rod 17 to rotate in the opposite direction through meshing with the drive gear 19, causing the two connecting plates 13 to move towards each other. The two heating half-rings 14 close and wrap around the cable.
[0036] The drive motor 4 is started, providing power to the drive wheel 3. The drive wheel 3 rotates, causing the ice-removing device to move along the power grid. The driven wheel 7 rotates along with the drive wheel 3, assisting the ice-removing device to move smoothly. During the movement, the heating half-ring 14 heats and melts the ice on the cable, thus achieving the ice-removing function.
[0037] The melted ice water drips from the cable. Since both heating half-rings 14 are directly above the collection box 8, the ice water drips directly into the collection box 8. The constant temperature plate 9 inside the collection box 8 maintains the water temperature and prevents the water from freezing again. When drainage is required, the control valve 11 on the drain pipe 10 is opened to drain the water from the collection box 8.
[0038] After use, adjust the telescopic rod 6 to retract, which will open the two heating half-rings 14. Then, remove the ice removal device from the cable.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
