Specific implementation mode

[0042] Example 1:

[0043] A self-propelled overhead line de-icing device, as Figure 1 shown, includes:

[0044] The rotating precessing component 1 is a cylindrical structure sleeved outside the transmission wire 5, and the inner side of the cylindrical structure has a meshing component 104 adapted to the stranded wire shape of the transmission wire 5;

[0045] The ice-breaking cone 2 is connected to both ends of the rotating precessing component 1;

[0046] The driving assembly 3 is rotatably connected to the rotating precessing component 1, and drives the rotating precessing component 1 to rotate on the transmission wire 5 through a transmission mechanism;

[0047] The commutation component 4 is slidably connected to the rotating precessing component 1, and changes the rotation direction of the driving assembly 3 and the rotating precessing component 1 by hitting one end of the transmission wire 5 with the top.

[0048] The ice-breaking cones 2 are located at both ends of the device, and the ice-breaking cones 2 at both ends are connected through the cylindrical structure of the rotating precessing component 1. When de-icing, the driving assembly 3 provides driving force for the rotating precessing component 1 to rotate on the transmission wire 5, thereby driving the ice-breaking cones 2 to rotate and de-ice on the transmission wire 5. The commutation component 4 is slidably connected to the rotating precessing component 1, and the top of the commutation component 4 is provided with a structure extending outward, which can collide with the transmission wire 5 when the device reaches one end of the transmission wire 5, so that the driving assembly 3 and the rotating precessing component 1 reverse, and further the device rotates and moves along the transmission wire 5 in the direction of the other end of the transmission wire 5 and de-ices.

[0049] The device uses the ice-breaking cones 2 to rotate on the transmission wire 5 for ice-breaking. The ice-breaking cones 2 can effectively break the hard rime on the transmission wire 5. The ice-breaking cones 2 are located at both ends of the cylindrical structure and can de-ice in both directions, so as to realize repeated moving de-icing;

[0050] Inside the rotary precession component 1, there is an engaging component 104 that can engage with the power transmission wire 5. By making full use of the threads formed by the spiral winding of the steel strands of the power transmission wire 5, it can rotate forward or backward, and movement can be achieved without setting up a driving wheel, driving the ice-breaking cone 2 to rotate and remove ice on the power transmission wire 5.

[0051] The driving component 3 is used to provide power for the rotating component through the transmission mechanism. The driving component 3 can also store electrical energy. When freezing rain comes, the driving motor 304 works, and the device removes ice while moving on the overhead line.

[0052] The commutation component 4 is used to, when the device moves to one end of the power transmission wire 5, collide with the power transmission wire 5 at the top and move in the reverse direction under the action of the driving force, so as to move back and forth on the power transmission wire 5 to remove ice, effectively preventing line icing.

[0053] Preferably, an inclination sensor is further provided on the rotary precession component 1. When the device winds the wire, the inclination sensor triggers the rotary precession component 1 to reverse, and ice breaking is carried out by repeatedly rotating forward and backward.

[0054] An inclination sensor is provided on the rotary precession component 1. The inclination sensor is used to prevent the device from getting stuck during rotation and thus winding the wire. When it is found that the device rotates as a whole by winding, the inclination sensor can trigger the gear to reverse, and ice breaking is achieved by repeatedly rotating forward and backward.

[0055] As Figure 2 shown, the rotary precession component 1 includes:

[0056] A transmission cylinder 101, which is a cylindrical structure with both ends open and is sleeved on the power transmission wire 5;

[0057] A turbine 102, which is sleeved on the power transmission wire 5 and is connected to both ends of the transmission cylinder 101;

[0058] A sleeve 103, with both ends respectively connected to the turbine 102 and the ice-breaking cone 2, and the engaging component 104 is arranged inside the sleeve 103;

[0059] The turbine 102 meshes with the driving component 3.

[0060] The rotary precession component 1 is installed on the power transmission wire 5 as Figure 3 shown. The rotary precession component 1 is a symmetric structure, and both ends of the transmission cylinder 101 are respectively connected to the turbine 102. As Figure 4 shown, the turbine 102 is connected to the ice-breaking cone 2 through the sleeve 103, and the symmetric structure at both ends can perform ice-removing operations in both the forward and reverse directions.

[0061] The driving assembly 3 is meshed with the turbine 102 to drive the device to rotate in a forward or reverse direction to de-ice.

[0062] A latch portion is provided between the sleeve 103 and the turbine 102 .

[0063] The ice-breaking cone 2 and the turbine 102 are connected via a fixed sleeve 103. Figure 5 As shown, a latch portion is provided between the sleeve 103 and the turbine 102, and a fixing block is inserted into the latch portion to prevent the turbine 102 from moving out of place.

[0064] Preferably, the engagement member 104 is a rotary precession column with rifling-shaped threads on the inner side, the rifling-shaped threads correspond to the strands of the power transmission wire 5, and forward or backward displacement is formed by rotating in forward and reverse directions.

[0065] The engaging component 104 is arranged on the inner side of the sleeve 103 and is in contact with the power transmission line 5. The engaging component 104 is provided with a rifling-shaped thread inside, which makes full use of the winding direction of the steel strand. The forward or backward displacement can be formed by rotating the precession column in the forward and reverse directions. This ingenious design does not require a driving wheel, and reasonably utilizes the characteristics of the guide rail, that is, the overhead power transmission line 5, to realize the movement of the device.

[0066] Preferably, ice-breaking teeth 201 are evenly distributed on the outer side of the ice-breaking cone 2.

[0067] Preferably, the ice-breaking teeth 201 are wedge-shaped ridge structures.

[0068] The ice breaker cone 2 is a cone structure, and the tip of the cone structure contacts the ice on the power transmission line 5. When working, the ice on the power transmission line 5 is broken by rotation. The surface of the cone structure is an inclined surface. During the de-icing process, the ice on the power transmission line 5 slides along the inclined surface of the cone structure, which plays a role in suppressing the accumulation of ice on the power transmission line 5. At the same time, the ice breaker cone 2 removes ice by rotation. The ice breaker cone 2 can adapt to ice of different shapes during the rotation process, increasing the adaptability of the ice breaker cone 2 during the ice breaking process. During the rotation process, the crushed ice can fall during the flipping process, thereby suppressing the occurrence of ice crawling.

[0069] The wedge-shaped prism structure of the ice-breaking teeth 201 helps the ice-breaking cone 2 to break ice on the power transmission line 5. When breaking ice, the wedge-shaped prism structure can easily crush ice columns during rotation, and the wedge-shaped prisms are not prone to jamming during the de-icing process. At the same time, the ice-breaking teeth 201 are arranged on the surface of the cone structure to reduce the contact area between the ice-breaking cone 2 and the ice during the ice-breaking process, reduce the ice formation area of ​​the cone structure, and thus reduce the adhesion area of ​​ice on the ice-breaking cone 2, thereby reducing the adverse effects of ice accumulation on the ice-breaking cone 2 and ensuring the normal use of the ice-breaking cone 2 during the ice-breaking process.

[0070] Preferably, a heating element is provided on the inner side of the ice-breaking cone 2.

[0071] The icebreaker cone 2 can be heated during the movement to prevent ice from adhering to the gears and causing jamming, thereby improving the de-icing efficiency. Furthermore, a vibration motor is provided inside the icebreaker cone 2, which can generate vibration while rotating, thereby better preventing ice from adhering and suppressing jamming.

[0074] A first worm 302 connected to both ends of the transmission shaft 301 and meshing with the turbine 102;

[0075] The second worm 303 is located in the middle section of the transmission shaft 301 and is meshedly connected to the driving motor 304 .

[0076] The transmission shaft 301 is used to connect the first worm 302 and the second worm 303 , and the transmission shaft 301 is connected to the reversing component 4 , and is supported by the reversing component 4 to mesh with the driving assembly 33 .

[0078] The second worm 303 is located in the middle of the transmission shaft 301 and meshes with the drive motor 304. The drive motor 304 controls the rotation of the second worm 303. The second worm 303 drives the transmission shaft 301 to rotate, thereby driving the first worms 302 at both ends of the transmission shaft 301 to rotate. The first worm 302 meshes with the turbine 102. The rotation of the turbine 102 drives the icebreaker 2 to rotate on the power transmission line 5 to remove ice.

[0079] The first worm 302 on the transmission shaft 301 is respectively connected to two turbines 102 before and after the transmission cylinder 101. When the first worm 302 is displaced, it drives the first worm 302 to engage with different turbines 102, and the device can automatically move forward and backward under the condition that the motor rotation direction remains unchanged.

[0080] Preferably, the driving component 3 obtains electric energy from the overhead line by means of coil CT energy extraction.

[0081] The driving component 3 obtains electric energy from the overhead transmission wire 5 by means of coil CT energy extraction and stores it in the battery. When freezing rain comes, the driving motor 304 works, and the device de-ices while moving on the overhead line.

[0082] As Figure 8 shown, the commutation component 4 includes:

[0086] The lever 401 is located at the top. The first support ring 402 and the second support ring 403 are sequentially connected to the lever 401.

The first support ring 402 and the second support ring 403 respectively install the transmission cylinder 101 and the transmission shaft 301 at intervals to maintain a certain distance, so that the first worm 302 on the transmission shaft 301 engages with the turbine 102.
