Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically to a de-icing device for high-voltage lines. Background Technology

[0002] High-voltage lines refer to power transmission lines with higher voltage levels, used to transmit electrical energy from power plants to substations or end users. Because high-voltage lines are generally erected at high altitudes, when faced with severe cold weather, the rain and snow that accumulate on the high-voltage lines freeze, which not only greatly increases the weight of the lines and the pressure on the supporting structure, but also affects the insulation performance of the high-voltage lines, causing line damage and dangerous situations. Therefore, high-voltage lines need to be de-iced using equipment in severe cold weather.

[0003] High-voltage line de-icing is a key measure to ensure the safe operation of the power grid. It mainly uses technologies such as robots and drones to deal with extreme weather. In the current technology, for safety and convenience, drones are generally used to knock ice off the high-voltage lines. However, drones need to maintain continuous flight. The reaction force generated by knocking on the high-voltage lines inevitably affects the stability of the drone's flight, making the drone prone to crashing. This not only causes economic losses but also affects the de-icing efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a high-voltage line de-icing device, which solves the problems mentioned in the background.

The box frame is equipped with a wire striking mechanism, which extends out of the box frame and overlaps with the bottom of the high-voltage line body. The hanger is equipped with a locking mechanism, which has a structure extending from the front of the hanger that cooperates with its hook.

[0009] Preferably, the striking rod is provided with a second rod seat, and a fixed shaft is rotatably provided on the second rod seat. A shaft seat is provided at one end of the fixed shaft near the hanger, and the shaft seat is mounted on the hanger.

[0010] Preferably, the frame includes a frame plate with a through slot for the upper structure of the wire striking mechanism to pass through. A cover is installed on the frame plate and covers the through slot.

[0011] Preferably, the limiting mechanism includes a frame mounted on a hanger, a second motor mounted on the frame, a lead screw mounted on the output shaft of the second motor, and a latching seat threaded onto the lead screw.

[0012] Preferably, the side of the buckle seat is provided with a buckle frame, the length of which corresponds to the width of the opening of the hook of the hanging bracket.

The side of the buckle frame is provided with a sliding groove, and the structure of the side of the buckle seat slides with the inner wall of the sliding groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This high-voltage line de-icing device is suspended from the high-voltage line body by a bracket. The mechanical kinetic energy provided by the striking mechanism continuously hammers the high-voltage line body, causing intermittent vibrations. This shakes off the snowflakes and ice cones covering the high-voltage line body, thereby achieving the de-icing effect. It eliminates the need for drones to knock and de-ic, which not only reduces the impact of de-icing on drones but also ensures the continuity of de-icing and improves de-icing efficiency.

[0014] 2. This high-voltage line de-icing device, through the cooperation of a limiting mechanism and a hanging bracket, after the hanging bracket is hooked onto the high-voltage line body, uses the limiting mechanism to seal the opening of the hanging bracket hook, so that the de-icing device is stably suspended on the high-voltage line body, avoiding the device falling due to vibration generated during de-icing, and improving the service life of the de-icing device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-7 A high-voltage line de-icing device includes: a bracket 1, a box frame 2 installed below the bracket 1, and both the bracket 1 and the box frame 2 are made of plates to form a box-type structure. The bracket 1 is processed into a hook shape near the top, and the high-voltage line body 4 is attached to the hook of the bracket 1. A guide frame 5 is installed on the bracket 1, and a suspension mechanism 6 is provided at the top of the hook of the bracket 1. The box frame 2 is equipped with a wire striking mechanism 3. The wire striking mechanism 3 extends out of the box frame 2 and overlaps with the bottom of the high voltage line body 4. A limiting mechanism 7 is installed on the hanger 1. The limiting mechanism 7 is a structure that extends out from the front of the hanger 1 and cooperates with its hook.

[0019] The guide frame 5 is installed at the end of the hook of the hanger 1, and the guide frame 5 is inclined along the direction of the end of the hook of the hanger 1.

[0020] That is, by installing the guide frame 5 to extend the hook of the bracket 1, it is convenient to use a drone to hang the bracket 1 on the high-voltage line body 4 when carrying out high-altitude de-icing, without having to spend time calibrating the drone's hovering position.

[0021] The suspension mechanism 6 includes a mounting base 61 installed on the top of the bracket 1, and a lifting ring 62 is provided on the mounting base 61, which is suspended on the drone.

[0022] That is, by setting a suspension mechanism 6 on the hanger 1, the drone can contact the de-icing device at intervals. During the de-icing process, the suspension mechanism 6 is used as a shock absorber to weaken the vibration force transmitted from the de-icing device to the drone, thereby improving the safety of the drone when it is transporting the de-icing device.

[0023] The wire striking mechanism 3 includes a reduction gearbox 31 mounted on the housing frame 2. A first motor 32 is provided at the bottom of the reduction gearbox 31. A crank 33 is mounted on the output shaft of the reduction gearbox 31. A spring 34 is sleeved on the journal of the crank 33. The end of the spring 34 away from the journal of the crank 33 is connected to a first rod seat 35. A striking rod 36 is provided inside the first rod seat 35. One end of the striking rod 36 passes through the housing frame 2 and is connected to a hammer for cooperating with the high-voltage line body 4.

[0024] The striking rod 36 is provided with a second rod seat 37, and a fixed shaft 38 is rotatably provided on the second rod seat 37. A shaft seat 39 is provided at one end of the fixed shaft 38 near the hanger 1, and the shaft seat 39 is installed on the hanger 1.

[0025] That is, by using the second rod seat 37 of the striking rod 36 to apply a fixed force to its central position, the striking rod 36 becomes a lever-like structure. Then, one end of the striking rod 36 is connected to the crank 33 by a spring 34. As the first motor 32 controls the operation of the reduction gearbox 31, the crank 33 continuously uses the spring 34 to pull the striking rod 36 to swing, which works in conjunction with the hammer at the other end of the striking rod 36 to intermittently hammer the high-voltage line body 4 to achieve the effect of de-icing.

[0026] The frame 2 includes a frame plate 21, on which a through groove 22 is provided for the upper structure of the wire striking mechanism 3 to pass through. A cover 23 is installed on the frame plate 21 and covers the through groove 22.

[0027] That is, by opening a through slot 22 in the shelf plate 21, the striking bar 36 extending from the box frame 2 to the outside through the through slot 22 has sufficient swing space. At the same time, the top of the through slot 22 is covered by the cover 23 to prevent falling ice or snowflakes from falling into the box frame 2 during the de-icing process.

[0028] The limiting mechanism 7 includes a frame 71 mounted on the hanger 1, a second motor 72 mounted on the frame 71, a lead screw 73 mounted on the output shaft of the second motor 72, and a latch seat 77 threaded onto the lead screw 73.

[0029] The buckle seat 77 has a buckle frame 74 on its side. The length of the buckle frame 74 corresponds to the width of the hook opening of the hanger 1. The buckle frame 74 has two sets of swing shafts 75. The swing shaft 75 located in the middle of the buckle frame 74 is mounted on the hanger 1 through a rotating shaft. The buckle frame 74 has a sliding groove 76 on its side. The structure of the buckle seat 77 slides against the inner wall of the sliding groove 76.

[0030] That is, such as Figure 7 As shown, the end of the hook frame 74 located in the slide groove 76 is arc-shaped. When the de-icing device is hooked onto the high-voltage line body 4, the hook of the hook frame 1 can be fully opened. After the loading is completed, the second motor 72 controls the hook seat 77 to descend, so that the hook frame 74 swings under the action of the central swing shaft 75, sealing the hook opening of the hook frame 1 and ensuring that the de-icing device is stably hooked onto the high-voltage line body 4.

[0031] 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.
