Description

Technical Field

[0001] This invention relates to the field of power transmission system technology, specifically to an overhead line de-icing device. Background Technology

[0002] Overhead line de-icing equipment removes ice and snow from overhead lines through current melting, mechanical de-icing, and non-power-out mode de-icing. Among them, DC de-icing converts alternating current into controllable direct current and uses the resistance of the conductor to heat up and melt the ice and snow. It has the advantages of high de-icing efficiency and long radiation line, thereby reducing the gravity load on overhead lines and improving the stability of the power transmission system. Existing de-icing equipment requires being moved to the de-icing station by car, which necessitates prolonged parking. Due to the damp and cold surrounding environment, a thin layer of ice exists on the ground, and water accumulated in the tire treads of the car's rear wheels cannot be drained in time, forming a water film that further reduces traction and increases the risk of slipping. At the same time, the presence of melted snow containing salt on the ground can corrode the insulation layer of the stretched-out electrical wires when they come into contact with it, and moisture can seep into the wires, potentially causing a short circuit to ground. Summary of the Invention

[0003] The technical problem that this solution addresses is: (1) How to solve the problem that due to the relatively humid and cold surrounding environment, there is thin ice on the ground, and the water in the tread grooves of the rear wheels of the car cannot be drained in time, which will form a water film, further reducing grip and increasing the risk of slipping; (2) How to solve the problem that the wires will come into contact with the melted snow containing salt on the ground, which will corrode the wire insulation layer and allow water to seep into the wire, potentially causing a short circuit to ground.

[0004] The objective of this invention can be achieved through the following technical solution: an overhead line de-icing device, comprising a vehicle body, an de-icing device being provided on the top of the vehicle body, the de-icing device being prior art, and an electrical wire being electrically connected to the output end of the de-icing device for melting ice and snow on the surface of the overhead line, a drying mechanism being provided on both the front and rear sides of the vehicle body for preventing the rear wheels of the vehicle from slipping, and a lifting mechanism being provided at the rear of the vehicle body for supporting the wire. The drying mechanism includes a mounting box that is fixedly connected to the vehicle body. A horizontally arranged adjusting cylinder is fixedly installed inside the mounting box, and a drying unit for drying the rear wheels of the vehicle is provided on one side of the mounting box.

[0005] A further technical improvement of the present invention is that: an electric push rod is fixedly installed at one end of the adjusting cylinder, the extended end of the electric push rod movably passes through the adjusting cylinder and is fixedly installed with a piston, and an electric heating rod is fixedly installed on the side of the piston away from the electric push rod.

[0006] A further technical improvement of the present invention is that a blower is fixedly installed on the inner wall of the mounting box below the regulating cylinder, and the output end of the blower is connected to the middle of the regulating cylinder through an air inlet pipe.

[0007] A further technical improvement of the present invention is that: the bottom of the end of the adjusting cylinder away from the electric push rod is connected to a hot air blowing pipe, and the output end of the hot air blowing pipe passes through the mounting box and is positioned between the corresponding rear wheel and the front wheel of the car.

[0008] A further technical improvement of the present invention is that: the drying unit includes a rain cover fixedly connected to the vehicle body, a longitudinally arranged cylinder is fixedly installed on the top of the rain cover, a lifting plate is fixedly connected to the extended end of the cylinder, and a rotating opening is provided on the side wall of the rain cover on one side of the lifting plate.

[0009] A further technical improvement of the present invention is that: a lever is fixedly installed at the extended end of the cylinder, and a U-shaped air blowing pipe is fixedly installed on the lifting plate on the front of the lever, with both output ends of the U-shaped air blowing pipe facing the rear wheel of the car.

[0010] A further technical improvement of the present invention is that: a telescopic hose is movably inserted into the top of the rain cover, the output end of the telescopic hose is connected to the middle of the U-shaped air blowing pipe, and the input end of the telescopic hose movably passes through the mounting box and is connected to the end of the regulating cylinder away from the hot air blowing pipe; by turning on the blower, the generated airflow will be injected into the U-shaped air blowing pipe along the telescopic hose, and then discharged through the two output ends of the U-shaped air blowing pipe to blow air onto the top of the rear wheels of the car, accelerating the drying speed of the top, and at the same time facilitating the flow of water accumulated in the tread grooves of the rear wheels to the ground, preventing the formation of a water film, by controlling the extension end of the cylinder from its shortest extension. At its longest, the lifting plate moves the U-shaped air hose downwards, so that the two output ends of the U-shaped air hose face the area between the rear wheels of the car and the ground, making it easier for the airflow to quickly dry the water between the rear wheels and the ground. Before the car is started, the extension end of the electric push rod is controlled to retract to its shortest position, so that the piston is located between the input end of the telescopic hose and the output end of the air intake pipe. Then the electric heating rod is turned on, so that the airflow is heated by the electric heating rod and blown out along the hot air blowing pipe between the corresponding rear wheels and front wheels of the car, thereby making it easier to melt the ice and snow on the ground, thus ensuring the traction of the rear wheels of the car and avoiding the risk of slipping.

[0011] A further technical improvement of the present invention is that the lifting mechanism includes two support frames, which are located on the front and rear sides of the vehicle body respectively, and the middle part of the support frame is rotatably connected to the vehicle body through a pin. A squeegee brush for cleaning the outer wall of the rear wheel of the vehicle is fixedly installed at one end of the support frame.

[0012] A further technical improvement of the present invention is that: the ends of the two support frames away from the wiper brush are jointly fixedly installed with support bars for lifting the wire; the ends of the two support frames near the wiper brush respectively movably pass through two rotating openings and are slidably connected to the corresponding two levers; during the simultaneous extension of the extended ends of the two cylinders, the two levers drive the corresponding support frames to rotate, so that the support bars lift the part of the wire in contact with the ground, preventing it from contacting the melted snow containing salt on the ground, thereby preventing the wire insulation layer from being corroded and preventing water from seeping into the wire and causing a short circuit to ground. During the rotation of the two support frames, the two wiper brushes clean the outer wall of the corresponding rear wheel of the car, preventing the attached water from corroding the wheel hub bolts of the rear wheel of the car.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In use, this invention involves turning on a blower, which generates airflow that flows along a telescopic hose into a U-shaped air-blowing pipe. The airflow then exits through the two output ends of the U-shaped air-blowing pipe, blowing air onto the top of the car's rear wheels to accelerate drying. This also facilitates the flow of water accumulated in the tire grooves of the rear wheels to the ground, preventing the formation of a water film. By controlling the extension of the cylinder from its shortest to its longest length, a lifting plate moves the U-shaped air-blowing pipe downwards, directing the two output ends of the U-shaped air-blowing pipe towards the area between the car's rear wheels and the ground. This allows the airflow to dry the water between the rear wheels and the ground more quickly. Before starting the car, the extension of the electric push rod is retracted to its shortest length, positioning the piston between the input end of the telescopic hose and the output end of the air intake pipe. Then, the electric heating rod is activated, heating the airflow before it flows along the hot air blowing pipe between the corresponding rear and front wheels of the car. This helps melt the ice and snow on the ground, ensuring the rear wheels have good grip and preventing the risk of slippage.

[0014] In use, as the protruding ends of the two cylinders extend simultaneously, two levers drive the corresponding support frames to rotate, causing the support bars to lift the part of the wire that is in contact with the ground, preventing it from coming into contact with melted snow containing salt on the ground. This prevents the wire insulation layer from being corroded and prevents water from seeping into the wire and causing a short circuit to ground. During the rotation of the two support frames, two squeegee brushes clean the outer wall of the corresponding rear wheel of the car, preventing the attached water from corroding the wheel hub bolts of the rear wheel.

[0022] Please see Figure 3 and Figure 4 As shown, a blower 44 is fixedly installed on the inner wall of the mounting box 46 below the regulating cylinder 47. The output end of the blower 44 is connected to the middle of the regulating cylinder 47 through the air inlet pipe 43.

[0023] Please see Figure 2 and Figure 3 As shown, the bottom of the adjusting cylinder 47 away from the electric push rod 45 is connected to a hot air blowing pipe 42.

[0025] Please see Figure 5 As shown, a lever 416 is also fixedly installed on the extended end of the cylinder 412. A U-shaped air pipe 417 is fixedly installed on the lifting plate 415 on the front of the lever 416. Both output ends of the U-shaped air pipe 417 are set towards the rear wheel of the car.

[0026] Please see Figure 3 and Figure 5As shown, the top of the aforementioned rain cover 413 is also movably fitted with a telescopic hose 411. The output end of the telescopic hose 411 is connected to the middle of the U-shaped air blowing pipe 417, and the input end of the telescopic hose 411 movably passes through the mounting box 46, and is connected to the end of the regulating cylinder 47 away from the hot air blowing pipe 42.

By controlling the extension end of the cylinder 412 from its shortest extension to its longest extension, the airflow can be controlled to achieve the desired effect. At its longest, the lifting plate 415 drives the U-shaped air pipe 417 downward, so that the two output ends of the U-shaped air pipe 417 face the area between the rear wheels of the car and the ground, making it easier for the airflow to dry the water between the rear wheels of the car and the ground. Before the car is started, the extended end of the electric push rod 45 is controlled to retract to its shortest length, so that the piston 48 is located between the input end of the telescopic hose 411 and the output end of the air intake pipe 43. Then the electric heating rod 49 is turned on, so that the airflow is heated by the electric heating rod 49 and blown out along the hot air blowing pipe 42 between the corresponding rear wheels and front wheels of the car, thereby making it easier to melt the ice and snow on the ground, thus ensuring the traction of the rear wheels of the car and avoiding the risk of slipping.

[0027] Please see Figure 2 and Figure 6 As shown, the lifting mechanism 3 includes two support frames 34, which are located on the front and rear sides of the vehicle body 5 respectively.

[0028] Please see Figure 2 , Figure 5 and Figure 6 As shown, the two support frames 34, located away from the wiper brush 31, are jointly fixedly equipped with support bars 33 for lifting the wire 2. The ends of the two support frames 34 near the wiper brush 31 respectively movably pass through two rotating openings 414 and are slidably connected to the corresponding two levers 416. During the simultaneous extension of the extended ends of the two cylinders 412, the two levers 416 drive the corresponding support frames 34 to rotate, causing the support bars 33 to lift the part of the wire 2 in contact with the ground, preventing it from contacting the melted snow containing salt on the ground, thereby preventing the insulation layer of the wire 2 from being corroded and preventing water from seeping into the interior of the wire 2 and causing a short circuit to ground. During the rotation of the two support frames 34, the two wiper brushes 31 clean the outer wall of the corresponding rear wheel of the car, preventing the attached water from corroding the wheel hub bolts of the rear wheel of the car.

At the same time, it facilitates the flow of water accumulated in the tread grooves of the rear wheels to the ground, preventing the formation of a water film. Then, by controlling the extended end of the cylinder 412 to extend from its shortest to its longest length, the lifting plate 415 drives the U-shaped air blower 417 to move downward, so that the two output ends of the U-shaped air blower 417 face the area between the rear wheels of the vehicle and the ground, making it easier for the blown airflow to dry the rear wheels of the vehicle and the ground more quickly. Before the car body 5 is started, the extended end of the electric push rod 45 is controlled to retract to its shortest length, so that the piston 48 is located between the input end of the telescopic hose 411 and the output end of the intake pipe 43.
