Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicles (UAVs), and in particular to a de-icing device for UAVs used in power transmission lines. Background Technology

[0002] Ice accumulation on power transmission lines significantly increases their weight, causing them to bear additional mechanical loads. This can cause the lines to stretch or even break, placing excessive stress on the power poles and towers, and in severe cases, potentially leading to tower collapse.

[0003] Most existing technologies use mechanical knocking to de-ice transmission lines. This involves using a knocking device suspended under a drone to knock on the ice covering the line. However, this de-icing method is inconvenient to operate. During use, the drone needs to be moved left and right to drive the knocking device to impact the ice covering the line. The entire de-icing process is time-consuming and inefficient. Sometimes, it is even necessary to repeat the process multiple times on the same section of the line to achieve the desired de-icing effect. Utility Model Content

[0013] (3) Beneficial effects

[0014] 1. By adjusting the position of the convex block, the stroke of the sliding block is adjusted, thereby changing the tension of the tension spring, and thus adjusting the striking force of the striking plate on the ice covering the transmission line. This allows the staff to set a suitable striking force according to the thickness of the ice covering the transmission line, thereby reducing the impact of the striking plate on the transmission line.

[0015] 2. The rotation of the arc-shaped strip drives the sliding column to slide upward, causing the hammer spring to store force. After the hammer spring releases its elasticity, it can repeatedly strike the ice on the upper side of the transmission line through the hammer head. While striking the ice on the transmission line, it can also reduce the adhesion between the ice and the transmission line. After the hammer head strikes the ice, the patting plate will strike the ice on the lower side of the transmission line again, which can completely remove the ice on the transmission line and improve the de-icing effect of the de-icing device.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] A type of unmanned aerial vehicle (UAV) de-icing device for power transmission lines, such as Figure 1-7 As shown, the device includes a drone 1, with a camera 101 connected to its end. A hot air chamber 2 is attached to the bottom of the drone 1 via a snap-fit ​​connection. A base plate 3 is fixedly connected to the bottom of the hot air chamber 2 via four support pillars. Two electric telescopic rods 301 are symmetrically fixedly connected to the upper surface of the base plate 3 via supports. A U-shaped frame 308 is fixedly connected to the end of each electric telescopic rod 301. A push block 302 is rotatably connected inside the U-shaped frame 308. The end of the push block 302 away from the electric telescopic rod 301 has an inclined surface. A lower triangular block 307, which is a right triangle, is fixedly connected to the middle of the lower surface of the push block 302. Two rectangular notches are symmetrically formed on the base plate 3. Slide grooves are formed on the opposite sides of the rectangular notches. A convex block 303 is slidably connected inside. The top of the convex block 303 has an inclined surface. A sliding block 304 is slidably connected to the lower side of the push block 302 and in the groove of the rectangular notch of the base plate 3. An upper triangular block 306 is fixedly connected to the upper surface of the sliding block 304. The upper triangular block 306 is also a right triangle. In the initial state, the right angle face of the upper triangular block 306 is in contact with the right angle face of the lower triangular block 307. Two round holes are opened on the other side of the rectangular notch of the base plate 3. A tension spring 305 is fixedly connected between the bottom surface of the round hole and the sliding block 304. Multiple positioning screws 313 are threadedly connected to the lower surface of the base plate 3 and on both sides of its rectangular notch.

[0027] Multiple positioning screws 313 are provided on both sides of the rectangular notch of the base plate 3. The positioning screws 313 are used to fix the position of the convex block 303. When it is necessary to adjust the position of the convex block 303, the positioning screws 313 are loosened outward to release the locking of the convex block 303. The convex block 303 is pushed inward or outward of the rectangular notch of the base plate 3. After the position of the convex block 303 is adjusted, the positioning screws 313 are tightened inward to lock the convex block 303 again. By adjusting the position of the convex block 303, the distance between it and the push block 302 is increased or decreased. In turn, by adjusting the extension length of the electric telescopic rod 301, the extension length of the tension spring 305 is controllable, and the striking force of the striking plate 310 is adjustable.

[0028] The bottom of the sliding block 304 is connected to a connecting post 309, and the end of the connecting post 309 is fixedly connected to a striking plate 310. The side of the striking plate 310 has multiple through holes, and a striking post 311 is slidably connected inside the through holes. A return spring 312 is fixedly connected between the striking post 311 and the striking plate 310.

[0029] A U-shaped frame 401 is fixedly connected to the bottom of the base plate 3. A hammer motor 402 is fixedly connected to the inner side of the U-shaped frame 401. The output shaft of the hammer motor 402 passes through the U-shaped frame 401 and is fixedly connected to the end of a rotating shaft 407. An arc-shaped strip 408 is fixedly connected to the outer arc-shaped side of the rotating shaft 407. A hammer spring 404 is fixedly connected to the bottom surface of the U-shaped frame 401 and to the outside of the rotating shaft 407. A hammer sleeve 405 is fixedly connected to one end of the hammer spring 404. A sliding column 409 is fixedly connected to the inner side of the hammer sleeve 405. A hammer head 406 is fixedly connected to the end of the hammer sleeve 405. A protective sleeve 403 is fixedly connected to the bottom of the base plate 3 and to the outside of the hammer spring 404.

[0030] The bottom of the hot air chamber 2 is symmetrically connected to two hot air pipes 201. The ends of the hot air pipes 201 are connected to arc-shaped hot air heads 202. Multiple hot air outlets 203 are opened on the arc-shaped inner side of the arc-shaped hot air head 202.

[0031] When de-icing power transmission lines, the drone 1 is controlled to fly above the power transmission line and observe the icing situation through the camera 101. The drone 1 is then controlled to position the arc-shaped hot air head 202 above the power transmission line. At this time, the hot air chamber 2 is turned on, and the hot air chamber 2 generates hot air, which is then transferred to the arc-shaped hot air head 202 through the hot air pipe 201. The hot air is then sprayed out through the hot air nozzle 203 of the arc-shaped hot air head 202 to preheat the icy power transmission line, which can reduce the adhesion of ice on the power transmission line to a certain extent.

[0032] When de-icing of the power transmission line is required, two electric telescopic rods 301 are activated. The telescopic ends of the electric telescopic rods 301 drive the push block 302 to slide outwards from the base plate 3 via the U-shaped frame 308. The push block 302 pushes the upper triangular block 306 and the sliding block 304 to slide outwards from the base plate 3 simultaneously via the lower triangular block 307 at its bottom, stretching the tension spring 305. When the inclined surface at the end of the push block 302 contacts the inclined surface at the end of the convex block 303, under the action of the inclined surface of the convex block 303, the push block 302 moves along the inclined surface of the convex block 303. The sliding block 302 slides upwards along the pivot at the other end within the U-shaped frame 308, causing the lower triangular block 307 to disengage from the right-angled surface of the upper triangular block 306. Under the action of the tension spring 305, the sliding block 304 quickly resets. The reset of the sliding block 304 drives the striking plate 310 to strike the ice on the transmission line through the connecting column 309. With the setting of the reset spring 312 on the striking plate 310, it can buffer backwards after the striking column 311 strikes the ice, which can moderately reduce the impact force of the striking plate 310 on the transmission line.

[0033] When the sliding block 304 is reset, the electric telescopic rod 301 retracts and resets. When the electric telescopic rod 301 is reset, it drives the lower triangular block 307 and the pushing block 302 to reset simultaneously through the C-shaped frame 308. When the lower triangular block 307 is reset, its inclined surface contacts the inclined surface of the upper triangular block 306, causing the pushing block 302 to rotate upward within the C-shaped frame 308. This causes the lower triangular block 307 to slide past the upper triangular block 306, so that the two right-angled surfaces of the upper triangular block 306 and the lower triangular block 307 are facing each other again.

[0034] When there is a lot of ice buildup on the upper side of the transmission line, the hammering motor 402 is activated. The hammering motor 402 drives the rotating shaft 407 to rotate via the output shaft. The rotation of the rotating shaft 407 causes the arc-shaped strip 408 to rotate. When the arc-shaped strip 408 rotates, the upper surface of the bottom of the arc-shaped strip 408 contacts the sliding column 409 and pushes the sliding column 409 to slide upward along the arc-shaped strip 408. At the same time, the upward sliding of the sliding column 409 drives the hammering sleeve 405 and the hammering head 406 to move upward synchronously and impact the hammering head. The hammer spring 404 is compressed. As the rotating shaft 407 rotates, the sliding column 409 moves upward along the arc strip 408. When the arc strip 408 reaches the top of the arc strip 408, the arc strip 408 and the sliding column 409 disengage. At this time, the hammer spring 404 resets and moves downward to push the hammer sleeve 405 and the hammer head 406 downward instantly, so that the hammer head 406 strikes the ice on the upper side of the power transmission line. The drone 1 is controlled to move along the power transmission line to strike the ice on its upper side.
