Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wire deicing device, in particular to a wire deicing device based on high-voltage transmission and transformation project. BACKGROUND

[0002] With the rapid development of social economy, the number and scale of high-voltage transmission and transformation projects are expanding, and gradually becoming the key part of power transmission. However, in recent years, with the frequent occurrence of extreme weather events, the ice disaster risk of high-voltage transmission lines has increased significantly. High-voltage transmission lines are usually located in remote or complex terrain areas, with special geographical location and overhead design, making these lines particularly susceptible to weather conditions. Winter harsh weather, such as low temperature and snow, often leads to rapid ice accumulation on the surface of the line. This ice layer not only increases the weight of the transmission line, but also may cause the wire to sag or even break, causing serious safety hazards.

[0003] The existing Chinese patent with publication number CN117175477B includes a mobile trolley, a lifting column is fixedly connected to the top of the mobile trolley near the central position, a guide plate is fixedly connected to the bottom right side of the C-shaped frame body, a support roller is rotatably connected to the top end of the support rod, a ring-shaped recess is formed in the central position of the outer surface of the support roller, a gear is fixedly connected to the outer surface of the support roller near the left end of the ring-shaped recess, a rolling module is arranged on the top central position of the C-shaped frame body, a ball is rotatably connected to the bottom end of the U-shaped frame, a limiting disc is fixedly connected to the outer surface of the ball near the bottom end of the U-shaped frame, and a pressing plate is fixedly connected to the side surface of the U-shaped frame near the limiting disc.

[0004] The above-mentioned device, when in use, pulls the U-shaped frame downward by the air cylinder, thereby moving the ball downward, and uses the support roller to support the high-voltage transmission wire. At this time, the first gear is driven to rotate by the servo motor, thereby driving the second gear to rotate. At this time, the ball and the support roller are used to extrude the high-voltage transmission wire, thereby crushing the ice layer attached to the surface of the high-voltage transmission wire. However, in actual use, the crushed ice blocks are difficult to completely separate from the wire, causing some small ice blocks to continue to adhere to the surface of the wire due to the residual adhesion force after extrusion, thereby affecting the deicing effect of the wire. Therefore, it is difficult to scrape and clean the ice blocks attached to the surface of the wire.

[0005] Therefore, we propose a wire deicing device based on high-voltage transmission and transformation project. SUMMARY

[0006] The purpose of the present application is to provide a wire deicing device based on high-voltage transmission and transformation project, which has the advantage of scraping and cleaning the ice blocks attached to the surface of the wire, and solves the problems in the background art.

[0008] Preferably, the two sides of the support plate near one end of the weight are symmetrically provided with rotating rods rotating reciprocally towards or away from each other through a pin shaft, the connecting grooves at the ends of the two rotating rods away from the support plate are movably connected with second rollers rolling on the surface of the wire in cooperation with the first roller through a pin shaft, and the opposite surfaces of the two rotating rods are fixedly connected with tension springs guiding the relative reset rotation of the rotating rods.

[0009] Preferably, the sliding grooves of the outer contours of the first roller and the second roller are fixedly connected with a plurality of evenly placed extrusion blocks, the outer contour of one side of the first roller is fixedly connected with a first tooth ring, and the outer contours of one side of the two second rollers are fixedly connected with second tooth rings meshing and transmitting with the first tooth ring.

[0010] Preferably, the eccentric position of the first roller away from the first tooth ring is movably connected with a pull rod pulling the U-shaped frame to move horizontally and reciprocally through a pin shaft, and the side of the U-shaped frame close to the pull rod is fixedly connected with a connecting seat, and the end of the pull rod away from the first roller is movably connected with the pull rod through a pin shaft.

[0011] Preferably, the cleaning mechanism comprises two half-circular rings rotating reciprocally in expansion or combination on the inner wall of the U-shaped frame, the inner walls of the two half-circular rings are movably connected with half-circular housings, the symmetric positions of one end of the two half-circular housings are fixedly connected with scrapers scraping the ice blocks on the surface of the wire, and the outer contours of the corresponding positions of the half-circular housings are fixedly connected with half-tooth rings.

[0012] Preferably, the U-shaped frame is provided with a limiting groove on the position corresponding to the half-toothed ring, the inner wall of the limiting groove is movably connected with a toothed plate which moves up and down reciprocally, and the toothed plate is engaged with the teeth on the half-toothed ring, the track rod is fixedly connected with an inclined plate through an external support, the inclined plate is provided with an inclined through slot which drives the toothed plate to move up and down reciprocally, the inner wall of the inclined through slot is movably connected with a sliding block, and one end of the sliding block is fixedly connected with the toothed plate.

[0013] Preferably, the U-shaped frame is provided with a knocking mechanism which knocks the surface of the wire, the knocking mechanism comprises a fixed block which is fixedly connected with one side of the U-shaped frame away from the connecting seat, the fixed block is penetrated and movably connected with a moving rod which moves horizontally reciprocally, one end of the moving rod away from the track rod is fixedly connected with a knocking block which knocks the surface of the wire, and the opposite surface of the knocking block and the fixed block is fixedly connected with a spring which drives the knocking block to move back.

[0014] Preferably, one end of the moving rod away from the knocking block penetrates the inner wall of the track rod and is fixedly connected with a cylindrical block, and the moving rod is movably connected with the track rod, and the track rod is fixedly connected with a plurality of protrusions which are evenly arranged on one side away from the U-shaped frame.

[0015] Compared with the prior art, the present application has the following advantages: By driving the first roller to rotate on the surface of the wire in the counterclockwise direction by the motor, and by engaging the teeth on the first tooth ring and the second tooth ring, the second roller is driven to rotate in the clockwise direction by the first tooth ring, so that the first roller and the second roller move on the wire in the direction away from the track rod, and the extrusion blocks arranged on the first roller and the second roller are accompanied by the rolling movement of the first roller and the extrusion blocks on the wire, so that the extrusion blocks can extrude and break the ice layer on the surface of the wire, and part of the broken ice is separated from the wire, which facilitates the subsequent cleaning of the ice attached to the surface of the wire.

[0016] Second, the tie rod on the first roller and the connecting seat on the U-shaped frame, with one end of the tie rod positioned off-center on the first roller, allows the tie rod to pull the U-shaped frame horizontally back and forth along the inner wall of the track rod under the action of the first roller. This allows the slider to pull the toothed plate up and down and back and forth along the inner wall of the support groove under the action of the inclined plate. As a result, the semi-gear ring drives the semi-circular shell to reciprocate and rotate along the inner wall of the semi-circular ring under the action of the toothed plate. The scraper on the semi-circular shell, which is in contact with the surface of the wire, rotates synchronously with the semi-circular shell and scrapes away the ice adhering to the surface of the wire. With the horizontal reciprocating movement of the U-shaped frame, the scraper can reciprocate and clean the ice adhering to the wire, thus improving the de-icing effect on the wire.

[0017] Third, as the U-shaped frame moves horizontally back and forth, the track rod moves synchronously back and forth along the inner wall of the track rod under the action of the U-shaped frame. Through the cylindrical block set on the moving rod and the protrusion set on the track rod, when the cylindrical block moves and contacts the protrusion, the cylindrical block pulls the moving rod and the striking block away from the conductor under the action of the protrusion. At this time, the spring is compressed and contracted under the action of the striking block. When the cylindrical block moves and disengages from the protrusion, the striking block can move quickly towards the conductor under the action of the spring force, so that the striking block strikes the conductor, and the conductor vibrates under the striking of the striking block, which promotes the removal of ice slag attached to the surface of the conductor under the action of vibration.

[0018] The combined use of the above structures solves the problem that, in actual use, the broken ice blocks are difficult to completely detach from the wires, causing some smaller ice blocks to continue to adhere to the wire surface due to residual adhesion after compression, affecting the de-icing effect of the wires and making it difficult to scrape and clean the ice blocks attached to the wire surface.
